摘　　要：采用GPRS技术作为数据传输手段的应用往往要求GPRS终端实时在线,且由GPRS终端主动发起建立联接。提出了一种非在线唤醒式GPRS通信模式,使得GPRS终端不必实时在线,而在需要时由上位机唤醒。这种方式实现了无需固定因特网IP地址的双向数据传输,并应用于电压监测系统中。The application taking GPRS as the methods of communication would suppose that the terminals based GPRS are always online and they actively call server for establishing the links of GPRS. An applied mode of GPRS technology that needn＇t the terminals based GPRS to be always on-line but to be awaken in time of need is presented. The applied mode bring bidirectional data transferring that doesn＇t use unchanged IP addresses of Interact to success, and it is applied in the monitoring system for the voltage of electric power.
