MUTE•When the voltage level of the mute pin is above 2V , the mute circuit is activated so that the output circuit will be muted.•When the mute pin #9 is open or the voltage of the mute pin #9 is below 0.5V , the mute circuit is deactivated and the output circuit operates normally.•When the mute circuit is activated, the voltage level of output pins becomes 1/2V CC (approximately).2. TSD (THERMAL SHUTDOWN)•If the chip temperature rises above 175°C, then the TSD (Thermal shutdown) circuit is activated and the output circuit is muted.•The V REF BG is the output voltage of the band-gap-referenced bias in circuit and acts as the input voltage of the TSD circuit.•The base-emitter voltage of the TR,Q11 is designed to turn-on at 460mA.V BE = V REF BG × R12 / (R11 + R12)=460mV•When the chip temperature rises up to 175°C, the turn-on voltage of the Q11 drops down to 460mV . (Hysteresis: 25°C) and Q11 turns on so the output circuit is muted.Pin #9Mute circuit High Turn-on Low Turn-off OpenTurn-off9Output driver biasV REF BGR11R12Q11Output driver biasKA3012D3. DRIVER•The gain of pre-op. Amplifier can be changed by manipulating amp input resistor or feedback resistor.•The voltage, V REF , is the reference voltage given by the bias voltage of the pin #6.•The level shift produces the current due to the difference between the pre amp output signal and the arbitrary reference (bias) signal. (The current produced as +∆I and −∆I is fed into the driver buffer. (CH1/CH4) The current produced as +2∆I and −2∆I is fed into the driver buffer. (CH2/CH3)•Driver buffer drives the power TR of the output stage according to the state of the input signal.•The output stage is the BTL driver and the motor is rotating in forward direction by operating TR Q1 and TR Q4.On the other hand, if TR Q2 and TR Q3 is operating, the motor is rotating in reverse direction.•When the output voltage of Pre-Amp (Pin 3, 12, 18, 25) is below the V REF , then the direction of the motor is in forward.•When the output voltage of Pre-Amp (Pin 3, 12, 18, 25) is above the V REF , then the direction of the motor in reverse.•The gain (A V ) of the drive circuit is as follows.4.

光盘驱动器
光盘驱动器在介绍光盘驱动器之前，有必要先了解一下光盘的概念。
光盘光盘作为软盘的替代者，不仅存储容量大、稳定性好，而且不易损坏，便于携带。
光盘可分为CD 、DVD 以及蓝光盘。
CD ：在CD 格式中，人们熟悉的一个或许是音乐CD ，CD 英文全称为Compact Disc,它的直径是12cm ，是使用聚碳酸酯透明树脂制作的存储盘，盘面内部有很薄的铝板，数据就存储在这个地方。
CD 的两面有很多螺旋型的细槽，这些槽叫做pit ，没有槽的平面部分叫做land ，数据通过pit 和land 重复存储，CD 可以分为存有数据的部分、开始记录数据的部分和结束部分，具体可分为如图所示的5个部分。
1中孔：用来固定盘面，以及用于旋转的孔，直径为15mm 。
2固定区域：用来固定中孔和数据区域的部分，直径为30mm 。
3：开始区域：记录CD 上存储的数据地址的区域，也叫做Lead-InArea 。
相当于音乐CD 上面记录音乐地址和各个曲目的演奏时间，相当于书的目录，若这个部分受损，不仅不能读入CD 中的数据，还不能识别CD ，直径为46~50 mm 。
4程序区域：若是音乐CD ，此处是存储音乐数据的地方，若是视频CD ，这里存储动态影像，若是程序CD ，则存储安装文件等数据，直径为50~116mm 。
5结束区域：实际数据的结束区域到CD 的边缘有0.5mm 的距离，这个区域也叫做Lead Out Area 。
CD 大致可以分为四种，出厂时就存储好数据的CD 、可以用CD-RW 驱动器等刻录设备记录数据的CD-R 、CD-RW 和可以存储电影等大量数据的DVD 。
各种CD 的特点 名称特点 工厂CD 工厂CD 是由基盘、反射层、保护层、和印刷层组成，通过激光束照射以后的反射光线读取数据。
CD-R CD-R 只可以存储一次数据，由4~5层组成。
CD-R 的最底层是聚碳酸脂，上面有凹槽。
这些凹槽会防止CD-RW 刻录机的激光头将发出的激光发射到错误的地方。

March 2006 Rev 11/99STTH3012Ultrafast recovery - 1200 V diodeMain product characteristicsFeatures and benefits■Ultrafast, soft recovery■Very low conduction and switching losses ■High frequency and/or high pulsed current operation■High reverse voltage capability ■High junction temperatureDescriptionThe high quality design of this diode has produced a device with low leakage current,regularly reproducible characteristics and intrinsic ruggedness. These characteristics make it ideal for heavy duty applications that demand long term reliability.Such demanding applications include industrial power supplies, motor control, and similarmission-critical systems that require rectification and freewheeling. These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications.The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.Order codesI F(AV)30 A V RRM 1200 V T j 175° C V F (typ) 1.30 V t rr (typ)57 nsPart Number Marking STTH3012D STTH3012D STTH3012WSTTH3012WCharacteristics STTH30122/91 CharacteristicsTo evaluate the conduction losses use the following equation: P = 1.60 x I F(AV) + 0.012 I F 2(RMS)Table 1.Absolute ratings (limiting values at 25° C, unless otherwise specified)Symbol ParameterValue Unit V RRM Repetitive peak reverse voltage 1200V I F(RMS)RMS forward current50A I F(AV)Average forward current, δ = 0.5T c = 105° C30A I FRM Repetitive peak forward currentt p = 5 µs, F = 5 kHz square300A I FSM Surge non repetitive forward current t p = 10 ms Sinusoidal 210A T stg Storage temperature range-65 to + 175°C T jMaximum operating junction temperature175°CTable 2.Thermal parametersSymbol ParameterValue Unit R th(j-c)Junction to case0.95°C/WTable 3.Static electrical characteristicsSymbol ParameterTest conditionsMin.TypMax.Unit I R (1)Reverse leakage currentT j = 25° C V R = V RRM20µAT j = 125° C 15150V F (2)Forward voltage dropT j = 25° C I F = 25 A2.1V T j = 125° C1.25 1.9T j = 150° C 1.201.8T j = 25° C I F = 30 A2.25T j = 125° C 1.35 2.05T j = 150° C1.301.951.Pulse test: t p = 5 ms, δ < 2 %2.Pulse test: t p = 380 µs, δ < 2 %STTH3012Characteristics3/9Table 4.Dynamic characteristicsSymbolParameterTest conditionsMin.TypMax.Unitt rrReverse recovery timeI F = 1 A, dI F /dt = -50 A/µs, V R = 30 V , T j = 25° C 115nsI F = 1 A, dI F /dt = -100 A/µs,V R = 30 V , T j = 25° C 5780I RM Reverse recovery current I F = 30 A, dI F /dt = -200 A/µs,V R = 600 V , T j = 125° C 2535A S Softness factor I F = 30 A, dI F /dt = -200 A/µs,V R = 600 V , T j = 125° C 1.5t fr Forward recovery time I F = 30 A dI F /dt = 100 A/µs V FR = 1.5 x V Fmax , T j = 25° C 550ns V FPForward recovery voltageI F = 30 A, dI F /dt = 100 A/µs,T j = 25° C6VFigure 1.Conduction losses versusFigure 2.Forward voltage drop versusCharacteristicsSTTH30124/9Figure 3.Relative variation of thermal impedance junction to caseFigure 4.Peak reverse recovery current versus dI F /dt (typical values)Figure 5.Reverse recovery time versusFigure 6.Reverse recovery charges versusFigure 7.Softness factor versus dI F /dt (typical values)Figure 8.Relative variations of dynamic parameters versus junctionSTTH3012Characteristics5/9Figure 9.Transient peak forward voltageFigure 10.Forward recovery time versus dI F /dtFigure 11.Junction capacitance versusreverse voltage applied (typicalPackage information STTH30126/92 Package informationEpoxy meets UL94, V0Cooling method: by conduction (C)Recommended torque value: 0.55 Nm (TO-220AC)Recommended torque value: 0.80 Nm (DO-247)Maximum torque value: 0.7 Nm (TO-220AC)Maximum torque value: 1.0 Nm (DO-247)STTH3012Package informationIn order to meet environmental requirements, ST offers these devices in ECOPACK®packages.

METTLER TOLEDO 腾达芯片科技 - 腾达芯片科技产品介绍说明书
METTLER TOLEDO is well established in the brewing industry, providing analytical inline instruments used by brewers around the world to help establish more cost-effective and reliable process automation. Previously our customers have been able to select systems for continuous measurement of dissolved oxygen, pH and conduc-tivity. However, we are pleased to announce the release of a new turbidity line with specific advantages for brewing – accompanied of course by the same high standard of application and service support that master brewers and quality assurance managers appreciate from a competent partner. What is turbidity?Turbidity is basically cloudiness in a liquid, which in wort or beer is caused by the presence of undissolved particles such as yeast, proteins or diatomaceous earth.These particles scatter the incident light and consequently lead to a milky or even opaque appearance of the liquid. The principle of light scattering is used in inline turbidimeters to measure the concentration of the undissolved particles:the higher the particle concentration the higher the scattered light intensity. The information on particle concentration is directly used to control individual process steps.What are the optical set-ups?Different particle concentration ranges require different optical set-ups for reliableTurbidity – new systemsfor brewing process optimization3and reproducible measurements. The measurement of forward and 90° scattered light has been proven to be the best optical method for turbidity in the range 0…100EBC (0…400 FTU). Higher particle concentrations – up to 250 g/l dry matter – are measured with backscattered light systems. The influence of different colored liquids on the intensity of the scattered light beams must be compensated by simultaneous measurement of a reference light beam or by the use of a light source emitting light in the near infrared range of the spectra. O ne of these techniques is always implemented in the turbidimeters described here.Trb 8300/InPro 8100 system still provides information for enhanced process control.In the filtration field, the most impor-tant applications are●control of centrifuges (similar to the measuring points in the brew house)●control of diatomaceous earth (Kieselgur) filtersEspecially in the last application, simultaneous measurement of forward and 90° scattered light provides important additional information on the type of par-ticle producing the turbidity. Typically, the 90° measurement value is between 0.3 and 2 EBC, representing turbidity caused by smaller particles such as proteins, which can be a key indicator for the shelf life of the final product. If this value is too high, the filter performance can be improved by changes in the Kieselgur dosage. Independent of this value, the for-ward scattered light signal should be smaller than the 90° signal. If this is not the case, then there are too many coarse particles in the beer. This is frequently an early warning sign of filter breakthrough,which could lead to very costly unsched-uled downtime.The recommended systems for the filtered beer measurement is ●a Trb 8300 F/S transmitter●an InPro 8500 dual-angle sensor (forward/90°)Similar to the InPro 8400 sensor line,InPro 8500 sensors are available in widely used line sizes, with different process con-nections and sapphire optics.What is your benefit?These new turbidity systems are complement-ary to the existing process analytical solu-tions from METTLER TOLEDO and help you to get the best out of your process.Brewery News 3METTLER TOLEDOBrewery News 3Turbidity – new systems for brewing process optimization New portable DO measurement system for control of your process quality INGOLD solutions –reliable quality helps to optimize productivity of brewing process Conductivity control in beer filler machinesMettler-Toledo GmbH Process Analytics Im Hackacker 15CH-8902 Urdorf Switzerland MarComCH-8902 Urdorf, Switzerland Mettler-Toledo GmbH ProzessanalytikD-35396 Gießen, Germany Archive MarComCH-8902 Urdorf, Switzerland andD-35396 Gießen, GermanySubject to technical changes. © Mettler-Toledo GmbH 01/04Printed in Switzerland.2What are the applications?In the brew house, the most important measurement points are after ●the lauter tun ●the whirlpool●hot wort centrifugesIn all three cases, inline turbidity measurement provides valuable informa-tion on the performance of the wort/solids separation process and allows immediate action to control the process. For example,after the lauter tun the switching point from lautering to wort pumping is opti-mized or the self-desludging mechanism of a centrifuge is controlled by the turbidity value in the clarified wort. The ideal meas-uring system consists of●a Trb 8300 F/S transmitter with high level operation●an InPro 8400 forward-scatter light sensor for direct pipe installation InPro 8400 flow-through sensors are available for the most common line sizes and process connections. The built-in sapphire optics easily withstand CIP solutions, minimizing the need for service and maintenance.In the fermentation sector, back-scattering systems provide important information on the cell growth of yeast in fermenters – the higher the cell concen-tration, the higher the light scattered back from the yeast cells. A typical measurement system consists of●a Trb 8300 transmitter with application-specific calibration routines●an InPro 8100 probe for direct installa-tion in a fermenter●an InFit 761 CIP housingDue to the backscattered light princi-ple and the use of fiber optic technology,the system shows a much wider linear measuring range than do competing absorption measurement systems. Even at extremely high yeast concentrations,where absorption systems have long reached their saturation limit, theIn Pro 8500.Typical METTLER TOLEDOINGOLDmodular sensor design.Brewery News 3METTLER TOLEDO3New portable DO measurement system for control of your process quality!InTap 4004 e.Time saving, easy handling and user-friendlyINGOLD InTap 4000e or InTap 4004e DO analyzers can easily be connected to your process.

Two wire units are available with HART ®or PROFIBUS ®interfaces.Brewery News 3METTLER TOLEDO4INGOLD solutions – reliable quality helps to optimize productivityThe most critical point for pH control throughout the brewing process is certainly during mashing because of the resulting impact upon the subsequent wort and beer processes. Control of dissolved oxygen is just as crucial because it is a fundamental indicator for taste, shelf life and clarity. Oxygen uptake at the lauter tun already has a direct influence on turbidity and color as well as on quality of bitterness. INGOLD DO, pH and newly introduced turbidity measurement systems ensure optimal inline process control and help you produce the highest quality beer possible.Comprehensive range of sterilizaThe retractable housing family InTrac 797 e and InTrac 799 e are opti-mally suited for sterilization of pH electrodes as well as for DO and turbidity sensors.

The service-friendly design of the inner body guarantees optimal cost-of-ownership.Approved hygienic design allows:●Safe insertion and withdrawal of sensors ●Sensor and electrode exchange during ongoing process.For standard applications METTLER TO LEDO offers an optimal and flexible solution with the well proven InTrac777 e.ProcessIn the final process of beer production,beer is filled into bottles or cans. In the filler machine, an amount of beer stored in a tank is filled into the bottles by applying differential pressure through CO 2injec-tion.In this process beer is filled into the bottle by applying CO 2 with a pressure of 0to 6 bar. During the CIP (Cleaning-in-Place) process, cleaning solution and wa-ter is circulating both in the machine and in the pipes that bring beer from the pro-duction to the packaging area.By the time the final wash-cycle of the CIP has ended, the pipes and filling machine are completely filled with water.When production is resumed, the actual filling process usually commences only after a specified time delay (drainage), and the first bottles then have to go through a lab analysis to determinate which bottlesBrewery News 3METTLER TOLEDOstart for the filling process, results in a ful-ly automated process with minimal loss of bottles and beer, as well as reduces labor costs.The METTLER TOLEDO solution METTLER TO LEDO offers a series of reliable sensors with a variety of process connections for this application. The system used is a Cond 7100 e, with an InPro 7002 series sensor, the sensor being installed in the pipe that feeds beer to the filler machine.6Conductivity control in beer filler machinesTransmitter Cond 7100 e.have to be rejected and which have the correct concentration of beer (no water contamination) to go to the market.If the waiting time is set too short, this results in a loss of bottles/cans. If the time is set too long, good beer will be sent down the drain. In addition, an operator is tied to the drain trying to visually determine by color the exact moment when water ends and beer starts.Typical process conditions:●Media: water, beer ●Pressure: up to 6 bar●Temperature: -2...25 °C, 28...77 °F ●Conductivity range: beer approx. 1500µS/cm, water approx. 100...150 µS/cm The use of a conductivity system to control the exact phase separation between water and beer ensure the correctParticularly useful in the Food &Beverage industry, conductivity is an ideal way to control the separation of two liquids with different conductivity values. One example is the measurement of conductivity of beer and water in the beer filler machine. By using a conductivity measuring sys-tem, the process is easily automated. Less reliable manual media separation based on visual surveillance through a sight glass becomes obsolete. This results in minimization of media loss, reduced labor cost and increased process safety and reliability.InPro 7002-VP .Precise phase detectionThe InPro7002-VP conductivity sensor is used to detect the exact switch-over from one phase to the other. This is registered very rapidly and precisely due to the fast response time for both conductivity and temperature measurements, combined with a factory-determined cell constant.Instantaneous response2-electrode conductivity systems have a response time of about one second. The distance between the sensor and the (filler)valve should be used in the calculation for setting the timing, provided installation possibilities allow for it. The sensor must be installed upstream from the valve.Minimization of media lossWith fast and precise phase detection,the loss of product in the installation can be remarkably minimized.7Brewery News 3METTLER TOLEDOCertified quality and materialsAccurate measurements are only possible if the cell constant has been de-termined accurately. 2-electrode sensors from METTLER TO LEDO are delivered with a certified and documented NIST/ASTM- traceable cell constant, en-suring the highest degree of accuracy. All materials in contact with the media are FDA compliant MaxCert TM , a package of certificates, supports the validation and qualification process.InstrumentationAs far as the transmitter is concerned,the Cond 7100 e series is the best choice for simple operation, precise and reliable measurements as well as low cost of ownership. The dual current outputs not only monitor the conductivity value but also temperature. The use of two com-pletely independent parameter sets allows/conductivitythe system to control phase detection very precisely, even if the conductivity change spans several orders of magnitude. With its unique user interface (pictographs) and continuous instrument and sensor diagnostics, this transmitter can be employed in all relevant process applications.tries, using tested and EHEDG-certified process connectors such as Tuchenhag-en Varivent, Neumo-BioControl, Tri-Clamp, and Ingold cap nut.●safe steam sterilization of the sensor in the flushing chamber●process connector and flushing chamber formed from a single piece of stainless steeel●complete absence of crevices or slits ●full hygienic cleaningThis completely new housing raises the bar for sanitary design. The InTrac 798 is cer-tified in accordance with EHEDG and 3-A guidelines. It is equipped with a state-of-the-art flushing chamber designed to opti-mize cleanability. The unit is outstanding for its array of advanced features such as:●totally drainable flushing chamber due to the positioning of the O-ring●use of 12 mm sensors of uniform length (120 mm)●suitability for applications in the food processing and pharmaceutical indus-With the InTrac798, METTLER TOLEDO INGOLD offers a retractable housing specifically designed for the pharmaceutical and food industries.

在进入过充保护状态后，当VDD电压降低到VREL1下方或者当电池组脱离充电器而接一个负载，且VDD介于VDET1与VREL1之间时VD1可以复位，即CoutPin输出变为高电位。
当放电电压低于过放检测电路的阈值VDET2时，经过一段固定的延迟时间，Dout Pin的输出即过放检测电路的输出VD2会变为低电位。
这时，若给电池充电，当电池电压上升到过放检测电路的阈值电压之上时，VD2恢复，Dout的输出电压变为高电平。
当有过流情况出现时，内部过流检测电路会检测到，经过一段固定的延迟时间后，VD3和Dout变为低电平，放电回路被切断。
这时，若将电池组从负载系统中分开，VD3会恢复使Dout 变为高电平。
当有外部短路电流时，短路保护电路会立即使Dout变为低电位，当外部短路电流消失后，Dout会转换为高电位。
在检测到过放之后，会通过关闭一些内部电路使电源电流非常低。
IC过充检测电路的延迟时间可以通过连接外部电容进行设置。

旋转LED立体显示系统设计
0 引言随着信息时代的科学技术发展,信息显示技术百花齐放,并各有所长。
LED显示具有亮度高、清晰度高、色彩鲜艳、视角宽等优点。
其独特的优越性,促使其从广播、电力等高端专业领域扩展到能源、工业、民生、公共管理等领域。
在此之前,LED全彩显示主要用于广告媒体、运动场地、舞台背景和市政工程。
现国内市场已经有了面向电子创意作品的小型单色旋转LED显示屏,但尚不具备广泛的应用条件。
颜色显示单一,显示面积过小,无法实时更新数据,性价比低等缺点,使之无法广泛应用。
[1]结合现有条件,本设计旨在于设计一款更大显示面积,更丰富色彩显示,提高旋转显示系统的性价比的旋转LED显示系统。
1 设计原理旋转LED显示系统由三个部分构成:机械结构、STM32主控板和MBI5024LED驱动板。
显示板在主控板程序的控制下,进行LED灯的控制显示,并在机械结构电机的带动下,线动成面,成为一个曲面的显示屏。
电路结构如图1所示。
本设计以STM32单片机为核心控制芯片。
由电机带动主板旋转达到一定速度稳定旋转,使单排LED旋转起来,给人的视觉效果将是一个圆柱或一个球形,并通过红外模块来感知旋转速度及起始位置。
本显示屏拟选用具有超高处理速度,超低功耗,稳定性能STM32RCT6 单片机为主要控制元件,采用16位MBI5024LED驱动芯片,行扫描、列驱动进行动态扫描。
彩屏通过选用了三基色[2-3]混色的原理,通过时间混色法,LED 点亮不同颜色,然后在同一空间位置重合实现。
2 整体设计机械结构:机械结构可以称作为本设计的骨架,后续的硬件电路和其搭载的软件系统都需要一个牢固稳定的机械结构方能稳定高效的工作,尤其对于本设计来说,高速旋转的叶片更是高度需求一个设计精良的骨架。
主控板电路:主控电路板电路原理图如图2所示,主控电路板以贴片式封装的STM32F103RCT6单片机为主控芯片,从嵌入式最小硬件系统组成上来说,主控芯片STM32采用ARM Cortex内核,48KRAM,256KROM单片机上I/O口均被引出,为后续开发留下空间。
