摘　　要：利用单片机通过市话网络实现对远程无人值守设备的状态进行监视与控制,系统由铃流检测、摘挂机电路、DTMF接收器和信号音发生器等部分组成。系统采用600 Hz信号音作为设备状态提示与主叫命令解析应答。能够自动实现被叫方的接续功能,验证主叫密码、识别控制命令,回复主叫设备状态提示,根据主叫命令,控制设备启停,系统具有密码设置界面,可采用远端设置或近端设置。In this paper, microcontroller is used to monitor and control remote unmanned equipments. The system is composed of ring detector, pick-hook circuit, DTMF tone receiver and tone generator, etc. 600 Hz tone is used as the device status command and the caller response. The called party＇s continuation function is automatically achieved, caller＇s passwords are certificated, control commands are identified, caller device＇s state prompt is replied. According to caller command, equipment is controlled to start and stop, the system has the password settings interface, the system can use the remote settings, or proximal settings.
