摘要
利用标准调制解调器使单片机电能耗用监控仪通过电话线路与主机通信，组成电能管理远程通信监控系统。它采用主机呼叫方式进行通信，可实现无人值守自动监测，数据传送可靠性高。介绍系统的基本组成原理。
A remote communication and supervisory system is designed with standard MODEM, and the power consumption monitor based on microcontroller is made to communicate with master computer via telephone line. With master calling communication, the power consumption can be monitored automatically with reliable data transmission. The system principle, hardware/software design are also described.
