本文介绍了利用微处理机及现代通信技术对我国县级电力局所属变电站之电力参数进行自动检测、无线数据传输及兼有无线电话系统的实现.该系统已投入运行,效果良好.县调度中心可以及时了解远离数十公里的各变电站的运行状况.它不仅可以用于电力系统,也完全适用于油田采油、水文及煤气罐测报系统. 本系统的检测终端机可对变电站电力参数自动进行定时、瞬时采集与处理,并以报表形式输出.由于数据传输时间短,为充分利用无线信道、数据传输与无线电话采用时分复用方式.下面重点讨论检测终端机.
This paper introduces the use of microprocessor and modern communication technology to the country’s county-level power substation belongs to the substation of the power parameters of automatic detection, wireless data transmission and the realization of both the wireless telephone system. The system has been put into operation with good results. It can keep abreast of tens of kilometers away from the substation operating conditions.It can not only be used in power systems, but also fully applicable to oil field, hydrology and gas tank measuring system.The testing terminal of the system can automatically time the substation power parameters , Instantaneous acquisition and processing, and output in the form of reports.Due to the short data transmission time, in order to make full use of wireless channels, data transmission and wireless phones using time-division multiplexing.
