摘要
设计了一种电器开关无线监控系统。系统实现了对多台电器电源的手动开关、本地计算机遥控开关、远程网络终端控制开关三种控制方式的实时或定时控制,同时在本地计算机和远程网络终端中提供了显示受控电器的电源通断状态。系统硬件通过USB接口实现与上位机的通信,通过无线电实现对电器的监控,并采用了跳频和时分技术,克服了无线传输过程中的同频干扰等问题。
A wireless monitoring system of electrical switch is designed. In this system, three control methods, including manual switch, local computer remote control switch, remote network terminal control switch, on more than one electrical power system have been implemented as real time or timing control. Meanwhile, the controlled electrical appliances＇ power state can be displayed both in local computer and remote network terminal through GUI （Graphical User Interface）. System hardware communicates with host computer via USB interface and radio implements monitoring of electrical. Moreover, same frequency interference in the wireless transmission process has been overcome due to the use of frequency-hopping and time division technology.
