数字电台在自来水管网监测调度系统中的应用

Application of Digital Radio in Tap Water pipe-network Detection Dispatcher System

本文介绍了数字电台在自来水管网监测调度系统中的设计、安装和使用。数字电台利用数字信号处理、纠错编码和数字调制解调等技术,克服了模拟电台在使用中出现的丢失数据包头、误码率高以及通信经常中断等缺点。实际应用表明用数字电台代替模拟电台的方案可大大提高系统的通信的稳定性和可靠性,为管网压力监测系统提供了一种较好的选择方案。

In this paper, the design , installment and application of digital broadcasting station in tap water pipe network detection dispatcher system are narrated. The shortcomings of analog broadcasting station such as losing heads of data frames, high error rate , frequent communication interrupt and so on are overcome by digital broadcasting stations which make use of the technology of digital signal processing, error correction code and digital modulation or demodulation. Practical application indicates the design which replaces analog broadcasting stations with digital one has enhanced the stability and reliablity of the correspondence of the system greafly and offered a better choice for pipe-network pressure monitoring system.
