摘要
采用双串口单片机作为电梯远程监控系统前端机的主控芯片,对电梯运行状态信号、故障信号和现场接入设备状态信号进行采集,同时与集成在前端机上的单片式MODEM进行串行通讯,并通过公共电话网与服务器连接,实现电梯故障远程报警、运行状态信息记录和服务器主动呼叫查询等功能。
A dual-serial-port single-chip with dual serial port is used as the main control chip on front terminal to collect the signals of elevator status,fault and field equipments, meanwhile communicates with the single-chip MODEM on front terminal in serial mode.It makes the front terminal communicate with the server through public telephone network,thus the functions of faults remote alarming,running status recording and server active calling is accomplished well.
