摘要
论述了在无人值守的远程计算机管理中,如何实现在远程控制计算机的电源开关。采用软、硬件相结合设计方案,ARM7嵌入式处理器为硬件核心,设备之间采用ZigBee通信,网关设备通过GPRS网络与服务器通信,电源控制设备通过GPIO口控制外部继电器开关,实现弱电控制交流强电输出的开关切换和模拟计算机的电源按键动作。以Delphi编写服务器端软件、被控计算机控制端软件和管理端软件,配合Or-acle 10g数据库和TCP/IP协议,实现电源控制功能。
That in unattended remote computer management,how to realize the remote control of the computer＇s power switch was discussed.The design was achieved by software and hardware.Hardware devices could be divided into the gateway device and power control equipment devices,which use ARM7 embedded processor for the hardware core and communicate by the use of ZigBee.Gateway device communicates with the server through GPRS network.Power control equipment devices controll external relay switches through the GPIO port,and this device controlls the exchange of weak intensity electrical output switching power supply and simulates computer keystrokes.Delphi was used to write server-side software,client software of controlled computer and management software,in conjunction with Oracle 10g database and TCP/IP protocol,the design of remote power control was implemented.
