摘要
介绍了“微机无线遥测系统”的基本原理、硬件电路的各组成部分及软件流程,着重论述研制过程中的关键问题:无线数据传输中主机与终端机的呼叫识别、传感器与终端机的I/V变换和A/D转换电路,并对数据传输的误码纠正和系统干扰问题进行了详细分析并提出了合理的解决方案。该系统为城市热力、煤气及自来水系统进行现代化管理提供了实践经验。
The authors expound the principle, hardware and software of the micro-computer radio telemetering system, and discuss several key problems encountered in the development process such as the calling identification of main computer and terminals in the process of radio data transmission, I/V transformation of sensors and terminals and A/D circuit. The development of this system provides practical experience for advanced administration of urban heat, gas, and water offering systems.
