介绍了基于单片机的移动式温度数据采集仪的硬件设计，串行红外接口的应用及用可视化编程工具VB6.0实现的WINDOWS界面的数据接收、处理软件。

关键词热电耦温度测量数据采集红外串口通信在电子工业中，随着整机集成度的提高和元器件的微型化、复杂化，在印制板上焊接元件时对各种焊接设备波峰焊、回流焊、SMT 等内的温度工艺要求越来越高。

这就需要一种可移动的温度数据采集仪器，能随传送带进入焊炉内，测量记录下不同焊点印制板上的焊盘孔、过孔等在焊炉内不同位置时的温度参数，并能将测量数据方便地传送给电脑，进行数据曲线的显示、分析和打印，以便制定和执行合适的工艺流程。

无线通信可以去除设备对线缆和连接器的依赖。

IrDA红外通信是一种低价且适应性广的短距离无线通信技术，只要通信双方都支持IrDA 协议，就能很快建立通信链路，实现数据交换。

近来红外通信在电子设备中得到了广泛的应用。

为此，研制了带有红外接口的移动式温度数据采集仪。

该仪器由可充电电池供电，以1Hz的采集率同时对≤8的温度测量点采集600s的数据。

温度测量范围为0℃～300℃，测量精度为满量程的1%。

测量数据存于E2PROM中，可掉电保存，直到下次采集将数据更新。

通过串行红外接口，仪器可将存储的测量数据方便地传送给电脑。

用可视化编程工具Visual Basic6.0制作了Windows界面的数据接收和处理软件，既方便硬件间的连接又便于测量数据的输出与分析。

下图是我根据此文制作的一个温度控制实验板。

线路与原文有些改动。

原文中的MAX144不易买到。

AD改用了TLC2543，基准电压用LM317调成4。

096V给AD，这样AD检测出来的值如果是全0温度就是0C。

如是全1温度刚好是409。

6度。

显示精度达到了0。

1度。

单片机用89C51。

感应出来的温度值可以通过液晶屏上显示，也可通过RS-232用计算机显示。

1 采集仪的硬件原理仪器的硬件设计贯彻了确保性能、缩小外形(特别是高度要求苛刻)、便于移动、降低功耗和机内隔热的原则。

74HC595D中⽂资料_数据⼿册_参数74HC595; 74HCT5958-bit serial-in, serial or parallel-out shift register with outputlatches; 3-stateRev. 6 — 12 December 2011Product data sheet1. General descriptionThe 74HC595; 74HCT595 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No.7A.The 74HC595; 74HCT595 are 8-stage serial shift registers with a storage register and3-state outputs. The registers have separate clocks.Data is shifted on the positive-going transitions of the shift register clock input (SHCP). The data in each register is transferred to the storage register on a positive-going transition of the storage register clock input (STCP). If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register.The shift register has a serial input (DS) and a serial standard output (Q7S) for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages. The storage register has 8 parallel 3-state bus driver outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.2.

MAX3362中文资料

General DescriptionThe MAX3362 low-power, high-speed transceiver for RS-485/RS-422 communication operates from a single +3.3V power supply. The device contains one differen-tial transceiver consisting of a line driver and receiver.The transceiver operates at data rates up to 20Mbps,with an output skew of less than 6ns. Driver and receiv-er propagation delays are guaranteed below 50ns. This fast switching and low skew make the MAX3362 ideal for multidrop clock/data distribution applications.The output level is guaranteed at +1.5V with a standard 54Ωload, compliant with RS-485 specifications. The transceiver draws 1.7mA supply current when unloaded or fully loaded with the drivers disabled.Additionally, the MAX3362 has a low-power shutdown mode, reducing the supply current to 1µA.The MAX3362 has a 1/8-unit-load receiver input imped-ance, allowing up to 256 transceivers on the bus. The MAX3362 is designed for half-duplex communication.The device has a hot-swap feature that eliminates false transitions on the data cable during circuit initialization.The drivers are short-circuit current limited, and a ther-mal shutdown circuit protects against excessive power dissipation.The MAX3362 is available in an 8-pin SOT package and specified over industrial and automotive tempera-ture ranges.ApplicationsClock/Data Distribution Telecom Equipment Security EquipmentPoint-of-Sale Equipment Industrial ControlsFeatureso Space-Saving 8-Pin SOT Package o Guaranteed 20Mbps Data Rate o Operates from a Single +3.3V Supply o 6ns (max) Transmitter and Receiver Skew o Hot-Swap Featureo Interoperable with +5V Logico Allows up to 256 Transceivers on the Bus o 1µA Low-Power Shutdown Mode o 1.7mA Operating Supply Current o -7V to +12V Common-Mode Range o Current Limiting and Thermal Shutdown o Half-Duplex Operationo Automotive Temperature Range VariantsMAX33623.3V , High-Speed, RS-485/RS-422 Transceiver inSOT Package________________________________________________________________Maxim Integrated Products 1Ordering Information19-2218; Rev 1; 5/02For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Typical Operating CircuitPin Configuration and Functional Diagram appear at end of data sheet.M A X 33623.3V , High-Speed, RS-485/RS-422 Transceiver in SOT Package 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICS(V= +3.3V ±5%, T = T to T , unless otherwise noted.

The device contains one differen-tial line driver and one differential line receiver. The dri-ver and receiver may be independently enabled. When disabled, outputs enter a high-impedance state.The transceiver guarantees data rates up to 20Mbps,with an output skew of less than 6ns. This low skew time makes the MAX3362 ideal for multidrop clock/datadistribution applications, such as cellular base stations.Driver and receiver propagation delays are below 50ns.The output level is guaranteed at 1.5V on a standard 54Ωload.The device has a hot-swap feature that eliminates false transitions on the data cable during circuit initialization.Also, drivers are short-circuit current limited and are protected against excessive power dissipation by ther-mal shutdown circuitry.Figure 7. Receiver Enable and Disable TimesM A X 33623.3V , High-Speed, RS-485/RS-422 Transceiver in SOT Package 10______________________________________________________________________________________The MAX3362 has a 1/8-unit-load receiver input imped-ance, allowing up to 256 transceivers to be connected simultaneously on a bus. The MAX3362 is designed for half-duplex communication.DriverThe driver transfers single-ended input (DI) to differen-tial outputs (A, B). The driver enable (DE) input controls the driver. When DE is high, driver outputs are enabled.These outputs are high impedance when DE is low. When the driver is enabled, setting DI low forces the noninverting output (A) low and inverting output (B)high. Conversely, drive DI high to force noninverting output high and inverting output low (Table 1).Drive RE high and DE low (disable both receiver and driver outputs) to enter low-power shutdown mode.ReceiverThe receiver reads differential inputs from the bus lines (A, B) and transfers this data as a single-ended output (RO). The receiver enable (RE ) input controls the receiver. Drive RE low to enable the receiver. Driving RE high places RO into a high-impedance state. When the receiver is enabled, RO is high if (A-B) ≥200mV. RO is low if (A-B) ≤-200mV.Drive RE high and DE low (disable both receiver and driver outputs) to enter low-power shutdown mode.Hot-Swap CapabilityHot-Swap InputWhen circuit boards are inserted into a hot or powered backplane, disturbances to the enable and differential receiver inputs can lead to data errors. Upon initial cir-cuit board insertion, the processor undergoes its power-up sequence. During this period, the output dri-vers are high impedance and are unable to drive the DE input of the MAX3362 to a defined logic level.Leakage currents up to 10µA from the high-impedance output could cause DE to drift to an incorrect logic state. Additionally, parasitic circuit board capacitance could cause coupling of V CC or GND to DE. These fac-tors could improperly enable the driver.When V CC rises, an internal pulldown circuit holds DE low for at least 10µs and until the current into DE exceeds 200µA. After the initial power-up sequence,the pulldown circuit becomes transparent, resetting the hot-swap tolerable input.Hot-Swap Input CircuitryThe MAX3362 enable inputs feature hot-swap capability.At the input there are two NMOS devices, M1 and M2(Figure 8). When V CC ramps from 0, an internal 10µs timer turns on M2 and sets the SR latch, which also turns on M1. Transistors M2, a 300µA current sink, and M1, a 30µA current sink, pull DE to GND through an 8k Ωresis-tor. M2 is designed to pull DE to the disabled state against an external parasitic capacitance up to 100pF that may drive DE high. After 10µs, the timer deactivates M2 while M1 remains on, holding DE low against three-state leakages that may drive DE high. M1 remains on until an external source overcomes the required input current. At this time, the SR latch resets and M1 turns off.When M1 turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CC drops below 1V, the hot-swap input is reset.For RE there is a complimentary circuit employing two PMOS devices pulling RE to V CC .Hot-Swap Line TransientThe circuit of Figure 9 shows a typical offset termination used to guarantee a greater than 200mV offset when a line is not driven (the 50pF represents the minimum parasitic capacitance that would exist in a typical appli-cation). During a hot-swap event when the driver isMAX33623.3V , High-Speed, RS-485/RS-422 Transceiver inSOT Package______________________________________________________________________________________11Figure 8.

Figures 10, 11, and 12 show the results of the MAX3362 during power-up for three different V CC ramp rates (0.1V/µs, 1V/µs, and 10V/µs). The photos show the V CC ramp, the single-ended signal on each side of the 100Ωtermination, as well as the differential signal across the termination.Low-Power Shutdown ModeLow-power shutdown mode is initiated by bringing both RE high and DE low. I n shutdown, the MAX3362 typi-cally draws only 1µA supply current.RE and DE may be driven simultaneously; the device is guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the device will enter shutdown.Enable times t PDZH, t PDZL, t PRZH and t PRZL in the Switching Characteristics table assume the device was not in a low-power shutdown state. Enable times t PDSH,t PDSL, t PRSH,and t PRSL assume the device was shut down. Drivers and receivers take longer to become enabled from low-power shutdown mode than from driver/receiver disable mode.Applications InformationPropagation DelaysFigures 5 and 6 show the typical propagation delays.Skew time is simply the difference between the low-to-high and high-to-low propagation delay. Small driver/receiver skew times help maintain a symmetrical mark-space ratio (50% duty cycle). Both the receiver skew time and driver skew time are under 6ns.256 Transceivers on the BusThe standard RS-485 receiver input impedance is 12k Ω(one-unit load), and a standard driver can drive up to 32 unit loads. The MAX3362 transceiver has a 1/8-unit-load receiver input impedance (96k Ω), allowing up to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices and/or other RS-485 transceivers with a total of 32 unit loads or less can be connected to the line.Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus con-tention. The first, a foldback current limit on the output stage, provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). The second, a ther-mal shutdown circuit, forces the driver outputs into a high-impedance state if the die temperature becomes excessive.Typical ApplicationsThe MAX3362 transceiver is designed for bidirectional data communications on multipoint bus transmission lines. The Typical Operating Circuit shows a typical net-work applications circuit. To minimize reflections, the line should be terminated at both ends in its character-istic impedance, and stub lengths off the main line should be kept as short as possible.1µs/divFigure 11.

双踪示波器介绍V-252

V-252型双踪示波器的使用说明作者：管理员更新时间：2007-11-11示波器种类、型号很多，功能也不同。

模拟、数字电路实验中使用较多的是20MHz或者40MHz的双踪示波器。

这些示波器用法大同小异，本节针对V-252型号示波器介绍其常用功能。

一、电源、示波管部分1. 荧光屏荧光屏是示波管的显示部分。

屏上水平方向和垂直方向各有多条刻度线，指示出信号波形的电压和时间之间的关系。

水平方向指示时间，垂直方向指示电压。

水平方向分为10格，垂直方向分为8格，每格又分为5份。

垂直方向标有0％，10％，90％，100％等标志，水平方向标有10％，90％标志，供测直流电平、交流信号幅度、延迟时间等参数使用。

根据被测信号在屏幕上占的格数乘以适当的比例常数(V／DIV，TIME／DIV)能得出电压值与时间值。

2．电源(POWER)示波器主电源开关位于荧光屏的右上角。

当此开关按下时，电源指示灯亮，表示电源接通。

3．辉度(INTENSITY)旋转此旋钮能改变光点和扫描线的亮度。

顺时针旋转，亮度增大。

观察低频信号时可小些，高频信号时大些。

以适合自己的亮度为准，一般不应太亮，以保护荧光屏。

4．聚焦(FOCUS)聚焦旋钮调节电子束截面大小，将扫描线聚焦成最清晰状态。

5.辉线旋转旋钮（TRACE ROTATION）受地磁场的影响，水平辉线可能会与水平刻度线形成夹角，用此旋钮可使辉线旋转，进行校准。

6. 通道1(CH1)的垂直放大器信号输入插座（CH1 INPUT）通道1垂直放大器信号输入BNC插座。

当示波器工作于X-Y模式时作为X信号的输入端。

7. 通道2(CH2)的垂直放大器信号输入插座（CH2 INPUT）通道2垂直放大器信号输入BNC插座。

当示波器工作于X-Y模式时作为Y信号的输入端。

8.垂直轴工作方式选择开关（MODE）输入通道有五种选择方式：通道1(CH1)、通道2(CH2)、双通道交替显示方式(ALT)、双通道切换显示方式(CHOP).叠加显示方式（ADD）。

595芯片管脚的作用

特点8位串行输入8位串行或并行输出存储状态寄存器，三种状态输出寄存器可以直接清除100MHz的移位频率输出能力并行输出，总线驱动串行输出；标准中等规模集成电路应用串行到并行的数据转换Remote control holding register.描述595是告诉的硅结构的CMOS器件，兼容低电压TTL电路，遵守JEDEC标准。

595是具有8位移位寄存器和一个存储器，三态输出功能。

移位寄存器和存储器是分别的时钟。

数据在SCHcp的上升沿输入，在STcp的上升沿进入的存储寄存器中去。

如果两个时钟连在一起，则移位寄存器总是比存储寄存器早一个脉冲。

移位寄存器有一个串行移位输入（Ds），和一个串行输出（Q7’）,和一个异步的低电平复位，存储寄存器有一个并行8位的，具备三态的总线输出，当使能OE时（为低电平），存储寄存器的数据输出到总线。
