摘　　要：设计开发一种基于公共电话网络的智能远程监测系统。系统由上位控制中心和下位监测终端组成。控制器采用低功耗MSP430F149单片机,由HT9200A和HT9170B实现DTMF拨码和译码,经监测终端将监测信息通过公用电话网络传输至控制中心,控制中心再对监测信息进行处理并将信息通过GSM网络发送至管理人员。系统在实际应用中取得了良好的监测效果,具有广泛的发展前景。The design of intellectual remote alarm system equipment mainly composed of single chip computer,DTMF receiver and transmitter chip, GSM module is introduced. The HT9200A is used for transmitting the DTMF signal and the HT9170B is used for decoding the DTMF signal. If the anomaly things happened,the detection information can be send to the information processing center through the telephone network, and the detection information can he send to the managers through the GSM networks for achieving the purpose of detection. In practical applications, the system works well and has a broad development prospects.
