摘　　要：针对DX-600发射机在温度监测中存在的不足，构建了多点温度巡回检测系统，实现发射机36个点的温度检测。分析了系统的整体功能需求并介绍了系统的总体结构；提出了采用AD590电流输出型集成温度传感器作为测温元件；利用信号调理电路输出与摄氏温度成跣L生比例关系的电压信号，并使用数显电压表结合CIM051八路模拟开关，实现苓地温度的显示。另外对36个点逐个依次送至STM32F103RCT6微控制器的选通电路进行了说明，阐述了V／F光纤F／V远距离模拟电压传输方案。同时，对系统的软件部分进行了简要的介绍。In view of the deficiency of DX - 600 transmitter in temperature monitoring, a muliti - point temperature circuit detection system is constructed, which can be used to detect the temperature of 36 points of transmitter. The overall functional requirements of the system are analyzed and the overall structure of the system is introduced. The ADS90 currant output integrated temperature sensor is used as the temperature measuring element, and the voltage signal with linear relation to temperature is output by the signal conditioning circuit. The digital display vohmeter combined with CD4051 eight analog switch is used to display the local temperature. In addition, the on - off circuit from 36 points to the STM32F103RCT6 nficrocontroller one by one is described, and the longdistance analog voltage trans- mission scheme of V/F - fiber - F/V is described. At the same time,the software part of the system is also briefly introduced.
