摘要
电网输出电压的监测是电业部门的一项重要工作。由于各变电站之间的距离较远,组建专用的计算机监测网络需要较多的资金,设备维护也有一定的困难。针对这种情况,用较低的成本开发出了基于USB接口电路的远程电压监测系统。USB接口可以连接多个不同的设备,支持热插拔,并具有自动检测的功能。介绍了USB接口电路在远程电压监测系统中的应用。从使用上看,系统运行稳定,维护方便,满足了设计要求。
Monitoring the output voltage by power grid is an important task of the power department. Since the distances among the converting stations are relatively long, setting up a special-purpose computer monitoring network requires more money, and its manitanee is rather difficult. In this case, we have developed a distant voltage monitoring system based on the USB interface circuit at low cost. Different kinds of equipment may be connected by the USB interface, electrified fitting and unpacking can be sustained with the function of automatic monitoring. The article intends to introduce the application of USB in the distant voltage monitoring system. In practice, it is stable in operation, convenient to maintain, meeting the designing requirements.
