中文摘要：
介绍了WIA中以MSP430F149单片机为核心的热电阻温度采集节点软硬件的设计方法。针对热电阻负温度信号设计了调理电路,并增加了电源监测的功能。该系统选用向下兼容HART协议的WIA无线模块,结合Matlab工具进行温度系数的远程标定。测试表明经标定修正后的节点在满足低功耗的前提下可实现较大区间温度的高精度测量,可应用于WIA环境中工业流程控制、工业安全监测等多种场合。
英文摘要：
The hardware and software design of RTD temperature accquisition node in WIA, with MCU MSP430F149 as the core, was introduced. By using the instrumentation amplifier with voltage reference pin, equipment could amplify the negative temperature signal collected by RTD adding function of power monitor on the base of temperature measurement. WIA wireless module supported HART protocol. Tem perature coefficient could be calculated remotely by the tool of Matlab. Practice measurement proved that the sensor node had advantages of high measurement accuracy and low power consumption and so on, which could be widely used in various domains under WIA situation, such as Industrial control flow and Process monitoring of industrial safety.
