The higher 1°C accuracy offered allows systems designers to safely reduce temperature guardbanding and increase system performance.The device can measure the temperature of a microprocessor using a diode-connected NPN or PNP transistor, which may be provided on-chip or can be a low-cost discrete device such as the 2N3906. A novel measurement technique cancels out the absolute value of the transistor’s base emitter voltage, so that no calibration is required. The second measurement channel mea-sures the output of an on-chip temperature sensor, to monitor the temperature of the device and its environment.The ADM1032 communicates over a two-wire serial interface compatible with System Management Bus (SMBus) standards.Under and over temperature limits can be programmed into the device over the serial bus, and an ALERT output signals when the on-chip or remote temperature measurement is out of range.This output can be used as an interrupt, or as an SMBus alert.The THERM output is a comparator output that allows CPU clock throttling or on/off control of a cooling fan.ADM1032–SPECIFICATIONS(T A = T MIN to T MAX, V DD = V MIN to V MAX, unless otherwise noted.)Parameter Min Typ Max Unit Test Conditions/CommentsPOWER SUPPLYSupply Voltage, V DD 3.0 3.30 5.5VAverage Operating Supply Current, I CC170215µA0.0625 Conversions/Sec Rate15.510µA Standby ModeUndervoltage Lockout Threshold 2.35 2.55 2.8V V DD Input, Disables ADC, Rising Edge Power-On Reset Threshold1 2.4VTEMPERATURE-TO-DIGITAL CONVERTERLocal Sensor Accuracy±1±3°C0 ≤ T A≤ 100°C, V CC = 3 V to 3.6 V Resolution1°CRemote Diode Sensor Accuracy±1°C60°C ≤ T D≤ 100°C, V CC = 3 V to 3.6 V±3°C0°C ≤ T D≤ 120°CResolution0.125°CRemote Sensor Source Current230µA High Level, Note 213µA Low Level, Note 2Conversion Time35.7142.8ms From Stop Bit to Conversion Complete(Both Channels) One-Shot Mode withAveraging Switched On5.722.8ms One-Shot Mode with Averaging Off(i.e., Conversion Rate = 32 or 64Conversions per Second)OPEN-DRAIN DIGITAL OUTPUTS(THERM, ALERT)Output Low Voltage, V OL0.4V I OUT = –6.0 mA2High Level Output Leakage Current, I OH0.11µA V OUT = V DD2SMBus INTERFACE2Logic Input High Voltage, V IH 2.1V V DD = 3 V to 5.5 VSCLK, SDATALogic Input Low Voltage, V IL0.8V V DD = 3 V to 5.5 VHysteresis500mVSCLK, SDATASMBus Output Low Sink Current6mA SDATA Forced to 0.6 VALERT Output Low Sink Current1mA ALERT Forced to 0.4 VLogic Input Current, I IH, I IL–1+1µASMBus Input Capacitance, SCLK, SDATA5pFSMBus Clock Frequency100kHzSMBus Timeout2564ms Note 3SMBus Clock Low Time, t LOW 4.7µs t LOW between 10% PointsSMBus Clock High Time, t HIGH4µs t HIGH between 90% PointsSMBus Start Condition Setup Time, t SU:STA 4.7µsSMBus Start Condition Hold Time, t HD:STA4µs Time from 10% of SDATA to 90%of SCLKSMBus Stop Condition Setup Time, t SU:STO4µs Time from 90% of SCLK to 10%of SDATASMBus Data Valid to SCLK Rising Edge250ns Time for 10% or 90% of SDATA to Time, t SU:DAT10% of SCLKSMBus Data Hold Time, t HD:DAT300µsSMBus Bus Free Time, t BUF 4.7µs Between Start/Stop ConditionSCLK Falling Edge to SDATA1µs Master Clocking in DataValid Time, t VD,DATSCLK, SDATA Rise Time, t R1µsSCLK, SDATA Fall Time, t F300nsNOTES1See Table VI for information on other conversion rates.2Guaranteed by Design, not production tested.3The SMBus timeout is a programmable feature.

When the ADM1032 is operating normally, the on-board A-to-D converter operates in a free-running mode. The analog input multiplexer alternately selects either the on-chip temperature sensor to measure its local tem-perature, or the remote temperature sensor. These signals are digitized by the ADC and the results stored in the Local and Remote Temperature Value Registers.The measurement results are compared with local and remote,high, low and THERM temperature limits, stored in nine on-chip registers. Out-of-limit comparisons generate flags that are stored in the Status Register, and one or more out-of limit results will cause the ALERT output to pull low. Exceeding THERM temperature limits cause the THERM output to assert low.The limit registers can be programmed, and the device con-trolled and configured, via the serial System Management Bus (SMBus). The contents of any register can also be read back via the SMBus.Control and configuration functions consist of:•Switching the device between normal operation and standby mode.•Masking or enabling the ALERT output.•Selecting the conversion rate.MEASUREMENT METHODA simple method of measuring temperature is to exploit the negative temperature coefficient of a diode, or the base-emitter voltage of a transistor, operated at constant current. Unfortu-nately, this technique requires calibration to null out the effect of the absolute value of V BE , which varies from device to device.The technique used in the ADM1032 is to measure the change in V BE when the device is operated at two different currents.This is given by:where:K is Boltzmann’s constant (1.38 × 10–23).q is charge on the electron (1.6 × 10–19 Coulombs).T is absolute temperature in Kelvins.N is ratio of the two currents.n f is the ideality factor of the thermal diode.The ADM1032 is trimmed for an ideality factor of 1.008.Figure 2 shows the input signal conditioning used to measure the output of an external temperature sensor. This figure shows the external sensor as a substrate transistor, provided for tem-perature monitoring on some microprocessors, but it could equally well be a discrete transistor. If a discrete transistor is used, the collector will not be grounded, and should be linked to the base. To prevent ground noise interfering with the measure-ment, the more negative terminal of the sensor is not referenced to ground, but is biased above ground by an internal diode at the D– input. If the sensor is operating in a noisy environment,C1 may optionally be added as a noise filter. Its value is typi-cally 2200 pF, but should be no more than 3000 pF. See the section on Layout Considerations for more information on C1.To measure ∆V BE , the sensor is switched between operating cur-rents of I and N × I. The resulting waveform is passed through a 65 kHz low-pass filter to remove noise, thence to a chopper-stabilized amplifier that performs the functions of amplification and rectification of the waveform to produce a dc voltage pro-portional to ∆V BE . This voltage is measured by the ADC to give a temperature output in two’s complement format. To further reduce the effects of noise, digital filtering is performed by aver-aging the results of 16 measurement cycles.Signal conditioning and measurement of the internal tempera-ture sensor is performed in a similar manner.TEMPERATURE DATA FORMATOne LSB of the ADC corresponds to 0.125°C, so the ADC canmeasure from 0°C to 127.875°C. The temperature data format is shown in Tables I and II.The results of the local and remote temperature measurements are stored in the Local and Remote Temperature Value Registers,and are compared with limits programmed into the Local and Remote High and Low Limit Registers.Table I.Temperature Data Format (Local Temperature and Remote Temperature High Byte)Temperature Digital Output 0°C 000000001°C 0000000110°C 0000101025°C 0001100150°C 0011001075°C 010********°C 01100100125°C 01111101127°C01111111REMOTE SENSING V OUT+TO ADC V OUT –C1 = 2.2nF TYPICAL, 3nF MAX.Figure 2.Input Signal Conditioning∆V n KT q In N BE f =()×()ADM1032–6–Status RegisterBit 7 of the Status Register indicates that the ADC is busy con-verting when it is high. Bits 6 to 3, 1, and 0 are flags that indicate the results of the limit comparisons. Bit 2 is set when the remote sensor is open circuit.If the local and/or remote temperature measurement is above the corresponding high temperature limit, or below or equal to, the corresponding low temperature limit, one or more of these flags will be set. These five flags (Bits 6 to 2) NOR’d together, so that if any of them is high, the ALERT interrupt latch will be set and the ALERT output will go low. Reading the Status Register will clear the five flag bits, provided the error conditions that caused the flags to be set have gone away. While a limit comparator is tripped due to a value register containing an out-of-limit measure-ment, or the sensor is open circuit, the corresponding flag bit cannot be reset. A flag bit can only be reset if the corresponding value register contains an in-limit measurement or the sensor is good. The ALERT interrupt latch is not reset by reading the Status Register, but will be reset when the ALERT output has been serviced by the master reading the device address, provided the error condition has gone away and the Status Register flag bits have been reset.When Flags 1 and 0 are set, the THERM output goes low to indicate that the temperature measurements are outside the programmed limits. THERM output does not need to be reset, unlike the ALERT output. Once the measurements are within the limits, the corresponding Status register bits are reset and the THERM output goes high.Table IV.

Configuration RegisterTwo bits of the Configuration Register are used. If Bit 6 is 0, which is the power-on default, the device is in operating mode with the ADC converting. If Bit 6 is set to 1, the device is in standby mode and the ADC does not convert. The SMBus does, however, remain active in Standby Mode so values can be read from or written to the SMBus. The ALERT and THERM O/Ps are also active in Standby Mode.Bit 7 of the configuration register is used to mask the alert output. If Bit 7 is 0, which is the power-on default, the output is enabled. If Bit 7 is set to 1, the output is disabled.Table II.Extended Temperature Resolution (RemoteTemperature Low Byte)Extended Remote TemperatureResolution Low Byte0.000°C000000000.125°C001000000.250°C010000000.375°C011000000.500°C100000000.625°C101000000.750°C110000000.875°C11100000ADM1032 REGISTERSThe ADM1032 contains registers that are used to store theresults of remote and local temperature measurements, high andlow temperature limits, and to configure and control the device.A description of these registers follows, and further details aregiven in Tables III to VII.Address Pointer RegisterThe Address Pointer Register itself does not have, or require, anaddress, as it is the register to which the first data byte of everyWrite operation is written automatically. This data byte is anaddress pointer that sets up one of the other registers for thesecond byte of the Write operation, or for a subsequent readoperation.The power-on default value of the Address Pointer Register is00h, so if a read operation is performed immediately after power-on without first writing to the Address Pointer, the value of thelocal temperature will be returned, since its register address is 00h.Value RegistersThe ADM1032 has three registers to store the results of Localand Remote temperature measurements. These registers arewritten to by the ADC only and can be read over the SMBus.Offset RegisterSeries resistance on the D+ and D– lines in processor packagesand clock noise can introduce offset errors into the remote tem-perature measurement. To achieve the specified accuracy onthis channel these offsets must be removed.The offset value is stored as an 11-bit, two’s complement valuein registers 11h (high byte) and 12h (low byte, left justified).The value of the offset is negative if the MSB of register 11h is 1and it is positive if the MSB of register 12h is 0. The value isadded to the measured value of remote temperature.The offset register powers up with a default value of 0°C, andwill have no effect if nothing is written to them.Table III.Sample Offset Register CodesOffset Value11h12h–4°C1111110000000000–1°C1111111100000000–0.125°C1111 1111111000000°C0000000000000000+0.125°C0000000000100000+1°C0000000100000000+4°C0000010000000000REV. 0REV. 0ADM1032–7–Consecutive ALERT RegisterThis value written to this register determines how many out-of-limit measurements must occur before an ALERT is generated.The default value is that one out-of-limit measurement gener-ates an ALERT . The max value that can be chosen is 4. The purpose of this register is to allow the user to perform some filter-ing of the output. This is particularly useful at the faster two conversion rates where no averaging takes place.Table VII.Number of “Out-of-Limit”Register Value Measurements Required yxxx 000x 1yxxx 001x 2yxxx 011x 3yxxx 111x4NOTESx = Don’t care bit.y = SMBus timeout bit. Default = 0. See SMBus section for more information.SERIAL BUS INTERFACEControl of the ADM1032 is carried out via the serial bus. The ADM1032 is connected to this bus as a slave device, under the control of a master device.There is a programmable SMBus timeout. When this is enabled the SMBus will timeout after typically 25 ms of no activity. How-ever, this feature is not enabled by default. To enable it, set Bit 7of the Consecutive Alert Register (Addr = 22h).The ADM1032 supports Packet Error Checking (PEC) and its use is optional. It is triggered by supplying the extra clock for the PEC byte. The PEC byte is calculated using CRC-8. The Frame Check Sequence (FCS) conforms to CRC-8 by the polynomial:C (x ) = x 8 + x 2 + x 1 + 1Consult SMBus 1.1 specification for more information ().ADDRESSING THE DEVICEIn general, every SMBus device has a 7-bit device address (except for some devices that have extended, 10-bit addresses). When the master device sends a device address over the bus, the slave device with that address will respond. The ADM1032 is avail-able with one device address, which is Hex 4C (1001 100).The serial bus protocol operates as follows:1.The master initiates data transfer by establishing a START condition, defined as a high-to-low transition on the serial data line SDATA, while the serial clock line SCLK remains high. This indicates that an address/data stream will follow.All slave peripherals connected to the serial bus respond to the START condition, and shift in the next eight bits, con-sisting of a 7-bit address (MSB first) plus an R/W bit, which determines the direction of the data transfer, i.e., whether data will be written to or read from the slave device.The peripheral whose address corresponds to the transmitted address responds by pulling the data line low during the low period before the ninth clock pulse, known as the Acknowl-edge Bit. All other devices on the bus now remain idle while the selected device waits for data to be read from or written Table V. Configuration Register Bit AssignmentsPower-On Bit Name FunctionDefault 7MASK10 = ALERT Enabled 01 = ALERT Masked 6RUN/STOP0 = Run 01 = Standby 5–0ReservedConversion Rate RegisterThe lowest four bits of this register are used to program the conversion rate by dividing the internal oscillator clock by 1, 2,4, 8, 16, 32, 64, 128, 256, 512, or 1024 to give conversion times from 15.5 ms (code 0Ah) to 16 seconds (code 00h). This register can be written to and read back over the SMBus. The higher four bits of this register are unused and must be set to zero. Use of slower conversion times greatly reduces the device power consumption, as shown in Table VI.Table VI.Conversion Rate Register CodesAverage Supply Current Data Conversion/sec mA Typ at V DD = 5.5 V 00h 0.06250.1701h 0.1250.2002h 0.250.2103h 0.50.2404h 10.2905h 20.4006h 40.6107h 8 1.108h 16 1.909h 320.730Ah641.230B to FFhReservedLimit RegistersThe ADM1032 has nine Limit Registers to store local and remote,high, low, and THERM temperature limits. These registers can be written to and read back over the SMBus.The high limit registers perform a > comparison while the low limit registers perform a < comparison. For example, if the high limit register is programmed with 80°C, then measuring 81o C will result in an alarm condition. If the Low Limit Register is programmed with 0°C, measuring 0°C or lower will result in Alarm condition. Exceeding either the Local or Remote THERM limit asserts THERM low. A default hysteresis value of 10°C is provided, which applies to both channels. This hysteresis may be reprogrammed to any value after power up (Reg 0x21h).One-Shot RegisterThe One-Shot Register is used to initiate a single conversion and comparison cycle when the ADM1032 is in standby mode,after which the device returns to standby. This is not a data register as such, and it is the write operation that causes the one-shot conversion. The data written to this address is irrel-evant and is not stored. The conversion time on a single shot is 96 ms when the conversion rate is 16 conversions per second or less. At 32 conversions per second the conversion time is 15.3 ms.This is because averaging is disabled at the faster conversion rates (32 and 64 conversions per second).REV. 0ADM1032–8–to it. If the R/W bit is a 0, the master will write to the slave device. If the R/W bit is a 1, the master will read from the slave device.2.Data is sent over the serial bus in sequences of nine clock pulses, eight bits of data followed by an Acknowledge Bit from the slave device. Transitions on the data line must occur during the low period of the clock signal and remain stable during the high period, as a low-to-high transition when the clock is high may be interpreted as a STOP signal.The number of data bytes that can be transmitted over the serial bus in a single Read or Write operation is limited only by what the master and slave devices can handle.3.When all data bytes have been read or written, stop condi-tions are established. In Write mode, the master will pull the data line high during the tenth clock pulse to assert a STOP condition. In Read mode, the master device will override the acknowledge bit by pulling the data line high during the low period before the ninth clock pulse. This is known as No Acknowledge. The master will then take the data line low during the low period before the tenth clock pulse, then high during the tenth clock pulse to assert a STOP condition.Any number of bytes of data may be transferred over the serial bus in one operation, but it is not possible to mix read and write in one operation because the type of operation is determined at the beginning and cannot subsequently be changed without starting a new operation.In the case of the ADM1032, write operations contain either one or two bytes, while read operations contain one byte, and per-form the following functions:To write data to one of the device data registers or read data from it, the Address Pointer Register must be set so that the correct data register is addressed, then data can be written into that register or read from it. The first byte of a write operation always contains a valid address that is stored in the Address Pointer Register. If data is to be written to the device, the write operation contains a second data byte that is written to the register selected by the address pointer register.This is illustrated in Figure 3a. The device address is sent over the bus followed by R/W set to 0. This is followed by two data bytes. The first data byte is the address of the internal data register to be written to, which is stored in the Address Pointer Register. The second data byte is the data to be written to the internal data register.When reading data from a register there are two possibilities:1.If the ADM1032’s Address Pointer Register value is unknown or not the desired value, it is first necessary to set it to the correct value before data can be read from the desired data register. This is done by performing a write to the ADM1032as before, but only the data byte containing the register read address is sent, as data is not to be written to the register.This is shown in Figure 3b.A read operation is then performed consisting of the serial bus address, R/W bit set to 1, followed by the data byte read from the data register. This is shown in Figure 3c.2.If the Address Pointer Register is known to be already at the desired address, data can be read from the corresponding data register without first writing to the Address Pointer Register and Figure 3b can be omitted.Table VIII.List of ADM1032 RegistersRead Address (Hex)Write Address (Hex)NamePower-On Default Not Applicable Not Applicable Address PointerUndefined00Not Applicable Local Temperature Value0000 0000 (00h)01Not Applicable External Temperature Value High Byte 0000 0000 (00h)02Not Applicable StatusUndefined0309Configuration 0000 0000 (00h)040A Conversion Rate0000 1000 (08h)050B Local Temperature High Limit 0101 0101 (55h) (85°C)060C Local Temperature Low Limit0000 0000 (00h) (0°C)070D External Temperature High Limit High Byte 0101 0101 (55h) (85°C)080E External Temperature Low Limit High Byte 0000 0000 (00h) (0°C)Not Applicable 0FOne-Shot10Not Applicable External Temperature Value Low Byte 0000 00001111External Temperature Offset High Byte 0000 00001212External Temperature Offset Low Byte0000 00001313External Temperature High Limit Low Byte 0000 00001414External Temperature Low Limit Low Byte 0000 00001919External THERM Limit 0101 0101 (55h) (85°C)2020Local THERM Limit 0101 0101 (55h) (85°C)2121THERM Hysteresis 0000 1010 (0Ah) (10°C)2222Consecutive ALERT 0000 0001 (01h)FE Not Applicable Manufacturer ID 0100 0001 (41h)FFNot ApplicableDie Revision CodeUndefinedWriting to address 0F causes the ADM1032 to perform a single measurement.

非倒转视频服务器提供了非常灵活的I/O模块来连接用户的安防设备,如传感器,报警器,灯光或门锁.通用I/O模块共有6个管脚.这些管脚可按它们的功能分成两种类别,分别是:RS485和数字输入输出.如果联接到串口上的设备是RS485接口的话,请接脚5和6.在配置页将接口转换成RS485,云台控制命令可直接通过脚5和6发送.如果距离太远导致无法正常工作,可外接电源拉高RS485信号.视频服务器提供1个数字输入和1个继电器出.脚1到脚2可用来联接外部传感器,它们的电压状态可按照配置页上的编程脚本来监控.继电器开头可以用来找开和关闭外接设备.3.2.4 状态指示灯当视频服务器启动时,系统将进行自检,检查系统的各个硬件.当接通电源时,电源指示灯下面的状态指示灯都会一个接一个地闪动,直到自检过程结束.如果有模块不正常,状态指示灯会按照附录A中的列表指示错误.如果自检通过,状态指示灯会关闭一段时间,然后按如下表显示.网络接口取决于所连接的UTP网线,调制解调器或串口连接线.如果交换机和视频服务器的连接良好的话,视频服务器会选择以太网接口.如果找不到以太网接口,而连接的调制解调器工作正常的话,网络接口会选择成调制解调器的PPP连接.如果上面的两种接口都找不到的话,视频服务器会试图用串口的PPP连接.网络接口条件LED1(心跳)

恢复按钮盒子上隐藏着一个用来恢复出厂设定值的按钮.当系统安装和工作不正常时,用包装中所带的小棍并按如下步骤操作来将系统恢复到原来的设置.用小棍伸进小孔按住恢复按钮.拔下和插上电源插头使系统重启.按住恢复按钮时,系统将会进行两次自检,而平时是一次自检,这可以从闪动的状态指示灯看出来.当摄像服务器的状态指示灯第二次闪动时,松开小棍.系统此时就会恢复出厂设定值.3.2.6 电源变压器将视频服务器联接到电源变压器的插孔上.当安装视频服务器时,开电是最后一个动作.第四章如何安装为方便的安装到各种环境下,视频服务器自动检测联接的接口,并按照最好的条件配置自已.也就是说,用户无需关心所联接摄像头是N制的还是PA L制的;所联接的网络是以太网还是MODEM,以太网的速度是10M或100M.如果联接的可调摄像头在支持列表中,用户无需复杂的配置就能即插即用.视频服务器支持以太网和调制解调器.以太网可以提供高带宽并得到最好的性能,同时拨号网络在通常的INTERNET应用是最常见的.参考相关的章节来询求你的网络环境的安装.如果两种环境都可用的话,推荐使用以太网,而且它也会被优先选用.从一种网络环境转移到另一种网络环境会清除前一种网络环境的设置.在下面的章节中,"用户"指可以使用视频服务器的人,"管理员"指除了能使用视频服务器外,而且还有root密码,能对它进行配置.管理员应该仔细阅读本手册,特别在安装过程中. 8北京华青紫博科技有限公司第五章以太网环境5.1 硬件安装在安装网络服务器之前,记下包装上的序列号以便将来使用.5.1.1 如何联接联接前关掉所有的周边设备.按照如下的步骤联接相关的设备.注意在联接好所有的设备之前不要插电源插头.5.1.2 开机请确保所有的电缆联执接正确和牢固,打开摄像头,传感器,报警设备然后将插头接到电源插座上.在自检完成并正常后,摄像服务器准备好进行软件配置. 这时,网络速度和视频调制模示是自动检测的.如果检测的视频调制模式不正确, 管理员可以在配置页改变设定.参见配置章.先将电源变压器的插头连接到视频服务器上,再插电源插头,这会减少电涌事故. 9北京华青紫博科技有限公司5.2 软件配置5.2.1使用安装软件为了远程配置摄像服务器,管理员应该记住新的视频服务器的序列号,并用它们做为身份认证和初始密码.当安装好视频服务器后,在PC上运行安装程序来定位刚安装的视频服务器.视频服务器也支持非WINDOWS下的手动安装模式.手动步骤以后讨论.当自检完成后,视频服务器会自动检测网络环境并自动配置.如果在网上有DHCP服务器的话,安装程序会得到给定的信息并显示序列号和每个视频服务器的IP地址.如果没有DHCP服务器的话,前一个IP地址会被显示.在这种情况下,新设备会显示0.0.0.0.当安装了多个设备后,程序将会显示多个设备.管理员可以点击"ASSIGNED"栏为"NO"的设备来进行配置.在当前IP地址栏显示的IP地址只是作为管理员的参考.如果管理员想用另外一个IP地址的话,直接修改下面的编辑框输入新的IP地址.如果想固定要机的IP地址的话,选择"无论何时系统启动时都使用此IP地址"来跳过进一步的设置,否则设备启动时都需要进行配置. 10北京华青紫博科技有限公司当IP和选项都输入完成后,点击"Set IP Address".弹出信息对话框通知管理员IP 地址是否合法.如果IP地址没有被其它网络设备使用的话,安装程序将继续.否则将弹出另外一个信息窗口显示IP地址冲突.在这种情况下,管理员应该咨询网络管理员来得到一个合法的IP地址.在显示成功设置IP后,管理员应该记住所设置的IP以便用户使用. 11北京华青紫博科技有限公司当点击了确定后,"设置"栏将会显示为"Y es".管理员可以直接点击"Link to selected camera"来用默认的浏览器连接指定的摄像机.当选择了"无论何时系统启动时都使用此IP地址"后,弹出对话框询问"服务器FTP端口"和"Root密码",这是因为它们被改变成了其它的数值.如果设定值丢失,恢复出厂设定并重新运行安装程序来安装.一旦安装结束后,管理员应该按照"第一次安装视频服务器"章来进行必要的检查和配置.有经验的管理员可以用定制的config.ini文件通过FTP来进行快速的设置.详细的步骤可以在"通过FTP快速配置"章找到. 12北京华青紫博科技有限公司如果想要用一个容易记住的名字来连接视频服务器的话,管理员可以在网络的名称服务器上配置一下.下面是一个例子:管理员已经设置视频服务器了一个固定的IP,而且想通过名字而不是难记的IP来连接它,管理员应该在DHCP服务器上为此视频服务器预留IP,并在域名服务器上将名称指定为对应的IP.当安装视频服务器时,设置它的IP为预留的IP.这样安装完成后就能用给定的名字来连接视频服务器了.5.2.2 用已有的程序来进行手动设定对应用环境是MA C,Linux,Unix或其它一些操作系统的环境下,我们还没有提供安装程序,一些常用的网络应用程序例如ARP和PING可以用来安装视频服务器.请先确认ARP和PING命令存在.首先,键入命令:arp -s "给定的IP地址" "网卡地址"这就在系统的名称表中增加了一项.网卡地址是指视频服务器的序列号,用如下的格式输入:uu-vv-ww-xx-yy-zz或uu:vv:ww:xx:yy:zz,选择哪种输入方式取决于操作系统.当名称项加入后,输入命令:ping "给定的IP地址"如果命令有回应的话,则IP地址设置成功,并可以用它来访问视频服务器.最开始的几个PING的反应会失败,因为此时视频服务器在进行自动配置.由于ARP和PING命令的语法取决于操作系统,所以请参考它们的帮助手册.5.3 第一次访问视频服务器当第一次连接到视频服务器时,管理员应该检查在系统配置页的安全和网络设定.为了防止非法使用,视频服务器提供两种权限,而且在访问前均需要用户名和密码.标准级别是用户模式,由20个用户权限组成.每个用户都能访问视频服务器,除了系统配置.这二十个用户权限也由管理员维护.最高的级别是ROOT模式,仅开放给管理员来做初始化,系统配置,用户管理和软件升级.管理员的用户由系统内定为"root".当连接上视频服务器后,用户将被提示来输入用户名和密码.与视频服务器的序列号相同的root密码将用来作系统的安装动作.管理员应该在做完初始化安装动作后立即修改密码以确保安全.新的root密码应该记好,因为没有办法获取或修复它.当改变完密码后,浏览器会弹出密码窗口要求用户再次输入新的密码.另一个重要的部分是网络设定.上面的软件配置使通过本地网络来访问视频服务器变得很容易.然而,管理员应该检查在系统配置页的网络配置,看看它是否符合已有的网络环境.安全和容易的方法是把它与已有的PC或工作站上的网络配置进行对比.前面章节中的软件安装只设置主机的IP地址和默认子网掩码为255.255.255.0.管理员应该按照本地网络来修改这个默认的子网掩码.如果需要的话,管理员也应该输入默认网关,主次DNS服务器. 13北京华青紫博科技有限公司默认状态下,视频服务器会在每次重启后要求管理员重新进行安装.如果网络设定确实不用每次重启后都改变的话,将此项安装选项失效.这样做会在下次视频服务器启动时跳过安装过程,直接使用前次的配置.如果使能此项安装选项,视频服务器会在下次启动时执行安装步骤.配置的详细描述在"如何使用"章.为了方便起见,相关图片也包含在内.第六章调制解调器环境6.1 硬件安装在安装视频服务器前,管理员应该记住包装上的序列号,因为它是最初的密码.为了使用拨号网络,网卡的接口应该断开,因为网卡是最优先的接口.当加电后,视频服务器会检测是否有外接的调制解调器连接在com口.当检测到有调制解调器后,芯跳指示灯会周期性地闪动.如果没有检测到调制解调器,视频服务器会默认为连接着串口连接线,并进行系统配置工作.此时电源指示灯下的两个指示灯都会点亮直到串口连接上.如果用户配置过远程拨号服务器或有ISP服务的帐号,视频服务器可以配置以在特定的条件下拨入到服务器.否则它会等待用户的呼叫来建立网络连接以提供服务.在下面的叙述中,拨入连接指视频服务器等待用户的拨入来建立点到点的连接.拨出连接指视频服务器拨出到另一个拨号网络服务器或任一ISP,要求点到点的连接.6.1.1 电缆连接关掉所有的周边设备的电源,然后将它们连接到视频服务器上.按照如下的顺序连接周边设备.注意在所有的周边设备连接好前,不要插上电源插头.没有 14北京华青紫博科技有限公司网卡第一次访问视频服务器时,管理员可以用随机携带的直接串口连接线直接连接到COM上.用直接串口连接线连接也是很方便的,它不需要调制解调器也不需要网卡.当输入必要的参数后,视频服务器就能用调制解调器来拨入到internet.6.1.2 接通电源在接通电源前,请确认所有的连线均连接牢固.打开摄像头,传感器和报警设备,最后将摄像服务器的插头插到接线板上.由于当系统重启时要进行所有的硬件检测,视频服务器应该在所有的周边设备打开前打开.先将电源变压器的插头连接到视频服务器上,再插电源插头,这会减少电涌事故.6.2 软件配置初次使用时,用户应该将产品自带的串口直连线连接到视频服务器的COM口和计算机的任一COM上.6.2.1

mAZL10355Data Sheet2.0 Functional DescriptionA functional block diagram of the ZL10355 OFDM demodulator is shown in Figure 3. This accepts an IF analog signal and delivers a stream of demodulated soft decision data to the on-chip Viterbi decoder. Clock, timing and frequency synchronization operations are all digital and there are no analog control loops except the AGC. The frequency capture range is large enough for all practical applications. This demodulator has novel algorithms to combat impulse noise as well as co-channel and adjacent channel interference. If the modulation is hierarchical, the OFDM outputs both high and low priority data streams. Only one of these streams is FEC-decoded, but the FEC can be switched from one stream to another with minimal interruption to the transport stream.Figure 3 - OFDM Demodulator DiagramThe FEC module shown in Figure 4 consists of a concatenated convolutional (Viterbi) and Reed-Solomon decoder separated by a depth-12 convolutional de-interleaver. The Viterbi decoder operates on 5-bit soft decisions to provide the best performance over a wide range of channel conditions. The trace-back depth of 128 ensures minimum loss of performance due to inevitable survivor truncation, especially at high code rates. Both the Viterbi and Reed-Solomon decoders are equipped with bit-error monitors. The former provides the bit error rate (BER) at the OFDM output. The latter is the more useful measure as it gives the Viterbi output BER. The error collecting intervals of these are programmable over a very wide range.ZL10355Data SheetFigure 4 - FEC Block DiagramThe FSM controller shown in Figure 3 controls both the demodulator and the FEC. It also drives the 2-wire bus to the tuner. The controller facilitates the automated search of all parameters or any sub-set of parameters of the received signal. It can also be used to scan any defined frequency range searching for OFDM channels. This mechanism provides the fast channel scan and acquisition performance, whilst requiring minimal software overhead in the host driver.The algorithms and architectures used in the ZL10355 have been optimized to minimize power consumption.2.1 Analog-to-Digital ConverterThe ZL10355 has a high performance 10-bit analog-to-digital converter (ADC) which can sample a 6, 7 or 8MHz bandwidth OFDM signal, with its spectrum centred at:•36.17MHz IF•43.75MHz IF•5-10MHz near-zero IFAn on-chip programmable phase locked loop (PLL) is used to generate the ADC sampling clock. The PLL is highly programmable allowing a wide choice of sampling frequencies to suit any IF frequency, and all signal bandwidths.2.2 Automatic Gain ControlAn AGC module compares the absolute value of the digitized signal with a programmable reference. The error signal is filtered and is used to control the gain of the amplifier. A sigma-delta modulated output is provided, which has to be RC low-pass filtered to obtain the voltage to control the amplifier.The programmable AGC reference has been optimized. A large value for the reference leads to excessive ADC clipping and a small value results in excessive quantization noise. Hence the optimum value has been determined assuming the input signal amplitude to be Gaussian distributed. The latter is justified by applying the central limit theorem in statistics to the OFDM signal, which consists of a large number of randomly modulated carriers. This reference or target value may have to be lowered slightly for some applications. Slope control bits have been provided for the AGCs and these have to be set correctly depending on the gain-versus-voltage slope of the gain control amplifiers.ZL10355Data SheetThe bandwidth of the AGC is set to a large value for quick acquisition then reduced to a small value for tracking. The AGC is free running during OFDM channel changes and locks to the new channel while the tuner lock is being established. This is one of the features of ZL10355 used to minimize acquisition time. A robust AGC lock mechanism is provided and the other parts of the ZL10355 begin to acquire only after the AGC has locked.2.3 IF to Baseband ConversionSampling a 36.17MHz IF signal at 45MHz results in a spectrally inverted OFDM signal centred at approximately8.9MHz. The first step of the demodulation process is to convert this signal to a complex (in-phase and quadrature) signal in baseband. A correction for spectral inversion is implemented during this conversion process. Note also that the ZL10355 has control mechanisms to search automatically for an unknown spectral inversion status.2.4 Adjacent Channel FilteringAdjacent channels, in particular the Nicam digital sound signal associated with analog channels, are filtered prior to the FFT.2.5 Interpolation and Clock SynchronizationZL10355 uses digital timing recovery and this eliminates the need for an external VCXO. The ADC samples the signal at a fixed rate, for example, 45.056MHz. Conversion of the 45.056MHz signal to the OFDM sample rate is achieved using the time-varying interpolator. The OFDM sample rate is 64/7MHz for 8MHz and this is scaled by factors 6/8 and 7/8 for 6 and 7MHz channel bandwidths. The nominal ratio of the ADC to OFDM sample rate is programmed in a ZL10355 register (defaults are for 45MHz sampling and 8MHz OFDM). The clock recovery phase locked loop in the ZL10355 compensates for inaccuracies in this ratio due to uncertainties of the frequency of the sampling clock.2.6 Carrier Frequency SynchronizationThere can be frequency offsets in the signal at the input to OFDM, partly due to tuner step size and partly due to broadcast frequency shifts, typically 1/6MHz. These are tracked out digitally, up to 1MHz in 2K and 8K modes, without the need for an analog frequency control (AFC) loop.The default frequency capture range has been set to ±286kHz in the 2K and 8K mode. However, these values can be increased, if necessary, by programming an on-chip register (see 7.4.1). It is recommended that a larger capture range be used for channel scan in order to find channels with broadcast frequency shifts, without having to adjust the tuner. After the OFDM module has locked (the AFC will have been previously disabled), the frequency offset can be read from an on-chip register.2.7 Symbol Timing SynchronizationThis module computes the optimum sample position to trigger the FFT in order to eliminate or minimize inter-symbol interference in the presence of multi-path distortion. Furthermore, this trigger point is continuously updated to dynamically adapt to time-variations in the transmission channel.2.8 Fast Fourier TransformThe FFT module uses the trigger information from the timing synchronization module to set the start point for an FFT. It then uses either a 2K or 8K FFT to transform the data from the time domain to the frequency domain. An extremely hardware-efficient and highly accurate algorithm has been used for this purpose.ZL10355Data Sheet 2.9 Common Phase Error CorrectionThis module subtracts the common phase offset from all the carriers of the OFDM signal to minimize the effect of the tuner phase noise on system performance.2.10 Channel EqualizationThis consists of two parts. The first part involves estimating the channel frequency response from pilot information. Efficient algorithms have been used to track time-varying channels with a minimum of hardware.The second part involves applying a correction to the data carriers based on the estimated frequency response of the channel. This module also generates dynamic channel state information (CSI) for every carrier in every symbol.2.11 Impulse FilteringZL10355 contains several mechanisms to reduce the impact of impulse noise on system performance.2.12 Transmission Parameter Signalling (TPS)An OFDM frame consists of 68 symbols and a superframe is made up of four such frames. There is a set of TPS carriers in every symbol and all these carry one bit of TPS. These bits, when combined, include information about the transmission mode, guard ratio, constellation, hierarchy and code rate, as defined in ETS 300 744. In addition, the first eight bits of the cell identifier are contained in even frames and the second eight bits of the cell identifier are in odd frames. The TPS module extracts all the TPS data, and presents these to the host processor in a structured manner.2.13 De-MapperThis module generates soft decisions for demodulated bits using the channel-equalized in-phase and quadrature components of the data carriers as well as per-carrier channel state information (CSI). The de-mapping algorithm depends on the constellation (QPSK, 16QAM or 64QAM) and the hierarchy (α=0, 1, 2 or 4). Soft decisions for both low- and high-priority data streams are generated.2.14 Symbol and Bit De-InterleavingThe OFDM transmitter interleaves the bits within each carrier and also the carriers within each symbol. The de-interleaver modules consist largely of memory to invert these interleaving functions and present the soft decisions to the FEC in the original order.ZL10355Data Sheet2.15 Viterbi DecoderThe Viterbi decoder accepts the soft decision data from the OFDM demodulator and outputs a decoded bit-stream. The decoder does the de-puncturing of the input data for all code rates other than 1/2. It then evaluates the branch metrics and passes these to a 64-state path-metric updating unit, which in turn outputs a 64-bit word to the survivor memory. The Viterbi decoded bits are obtained by tracing back the survivor paths in this memory. A trace-back depth of 128 is used to minimize any loss in performance, especially at high code rates.The decoder re-encodes the decoded bits and compares these with received data (delayed) to compute bit errors at its input, on the assumption that the Viterbi output BER is significantly lower than its input BER.2.16 MPEG Frame AlignerThe Viterbi decoded bit stream is aligned into 204-byte frames. A robust synchronization algorithm is used to ensure correct lock and to prevent loss of lock due to noise impulses.2.17 De-interleaverErrors at the Viterbi output occur in bursts and the function of the de-interleaver is to spread these errors over a number of 204-byte frames to give the Reed-Solomon decoder a better chance of correcting these. The de-interleaver is a memory unit which implements the inverse of the convolutional interleaving function introduced by the transmitter.2.18 Reed-Solomon DecoderEvery 188-byte transport packet is encoded by the transmitter into a 204-byte frame, using a truncated version of a systematic (255,239) Reed-Solomon code. The corresponding (204,188) Reed-Solomon decoder is capable of correcting up to eight byte errors in a 204-byte frame. It may also detect frames with more than eight byte errors. In addition to efficiently performing this decoding function, the Reed-Solomon decoder in ZL10355 keeps a count of the number of bit errors corrected over a programmable period and the number of uncorrectable blocks. This information can be used to compute the post-Viterbi BER.2.19 De-scramblerThe de-scrambler de-randomizes the Reed-Solomon decoded data by generating the exclusive-OR of this with a pseudo-random bit sequence (PRBS). This outputs 188-byte MPEG transport packets. The TEI bit of the packet header may be set if required to indicate uncorrectable packets.2.20 MPEG Transport InterfaceMPEG data can be output in parallel or serial mode. The output clock frequency is automatically chosen to present the MPEG data as uniformly spaced as possible to the transport processor. This frequency depends on the guard ratio, constellation, hierarchy and code rate. There is also an option for the data to be extracted from the ZL10355 with a clock provided by the user.ZL10355Data Sheet 3.0 Interfaces3.1 2-Wire Bus3.1.1 HostThe primary 2-wire bus serial interface uses pins:•DATA1 (pin 5) serial data, the most significant bit is sent first.•CLK1 (pin 4) serial clock.The 2-wire bus address is determined by applying VDD or VSS to the SADD[4:0] pins.In TNIM evaluation applications, the 2-wire bus address is 0001 111 R/W with the pins connected as follows: ADDR[7]ADDR[6]ADDR[5]ADDR[4]ADDR[3]ADDR[2]ADDR[1]Not programmable SADD[1]SADD[0]VSS VSS VSS VDD VDD VDD VDDWhen the ZL10355 is powered up, the RESET pin9 should be held low for at least 50ms after VDD has reached normal operation levels. As the RESET pin goes high, the logic levels on SADD[4:0] are latched as the 2-wire bus address. ADDR[0] is the R/W bit.The circuit works as a slave transmitter with the lsb set high or as a slave receiver with the lsb set low. In receive mode, the first data byte is written to the RADD virtual register, which forms the register sub-address. The RADD register takes an 8-bit value that determines which of 256 possible register addresses is written to by the following byte. Not all addresses are valid and many are reserved registers that must not be changed from their default values. Multiple byte reads or writes will auto-increment the value in RADD, but care should be taken not to access the reserved registers accidentally.Following a valid chip address, the 2-wire bus STOP command resets the RADD register to 00. If the chip address is not recognized, the ZL10355 will ignore all activity until a valid chip address is received. The 2-wire bus START command does NOT reset the RADD register to 00. This allows a combined 2-wire bus message, to point to a particular read register with a write command, followed immediately with a read data command. If required, this could next be followed with a write command to continue from the latest address. RADD would not be sent in this case. Finally, a STOP command should be sent to free the bus.When the 2-wire bus is addressed (after a recognized STOP command) with the read bit set, the first byte read out is the contents of register 00.3.1.2 TunerThe ZL10355 has a General Purpose Port that can be configured to provide a secondary 2-wire bus. See register GPP_CTL address 0x8C.Master control mode is selected by setting register SCAN_CTL (0x62) [b3]=1.The allocation of the pins is: GPP0 pin 35=CLK2, GPP1 pin 36=DATA2.。

国内外压敏电阻型号及参数

国内外压敏电阻型号及参数压敏电阻220V电压的电路国内型号：MYG14K471（对应的国外型号：US 470NR-14D）MYG05K471（对应的国外型号：US 470NR-5D）22V左右的电路国内型号：MYG14K470（对应的国外型号：US 470NR-14D）MYG05K470（对应的国外型号：US 470NR-5D）。

压敏电阻型号及参数压敏电阻压敏电阻“压敏电阻"是中国大陆的名词，意思是在一定电流电压范围内电阻值随电压而变，或者是说"电阻值对电压敏感"的阻器。

英文名称叫“Voltage Dependent Resistor”简写为“VDR”, 或者叫做“Varistor"。

压敏电阻器的电阻体材料是半导体，所以它是半导体电阻器的一个品种。

现在大量使用的"氧化锌"（ZnO）压敏电阻器，它的主体材料有二价元素（Zn）和六价元素氧（O）所构成。

所以从材料的角度来看，氧化锌压敏电阻器是一种“Ⅱ-Ⅵ族氧化物半导体”。

在中国台湾，压敏电阻器称为"突波吸收器",有时也称为“电冲击（浪涌）抑制器（吸收器）”。

目录[]1、压敏电阻电路的“安全阀”作用2、压敏电阻的应用类型3、保护用压敏电阻的基本性能4. 压敏电阻的基本参数1、压敏电阻电路的“安全阀”作用2、压敏电阻的应用类型3、保护用压敏电阻的基本性能4. 压敏电阻的基本参数1、压敏电阻电路的“安全阀”作用压敏电阻有什么用？压敏电阻的最大特点是当加在它上面的电压低于它的阀值" UN"时，流过它的电流极小，相当于一只关死的阀门，当电压超过UN时，流过它的电流激增，相当于阀门打开。

利用这一功能，可以抑制电路中经常出现的异常过电压，保护电路免受过电压的损害。

2、压敏电阻的应用类型不同的使用场合，应用压敏电阻的目的，作用在压敏电阻上的电压/电流应力并不相同，因而对压敏电阻的要求也不相同，注意区分这种差异，对于正确使用是十分重要的。
