摘　　要：针对传统的人工抄表不仅费时费力,而且不便于用电量实时统计的情况,研究了基于现有GSM网络发展起来的通用分组无线服务技术(GPRS),提出了利用GSM手机移动上网功能,进行传送电力系统抄表数据的方法.基于GSM/GPRS GTM900模块,以单片机为核心,通过RS232/RS485接口,实现了数据终端电能表与无线传输的连接,并备有A/D转换接口,可实现模拟信号的直接采集与传输.The traditional manual meter reading is not only time-consuming and laborious, but also not easy to obtain real-time statistics of electricity consumption. According to this condition, the General Packet Radio Service （GPRS）was described based on the existing GSM network, and a method of transmitting the meter reading data to power system was proposed via using of GSM mobile phones for Internet access. The system which includes the GSM/GPRS GTM900 module, the single-chip microcomputer and the RS232/RS485 interface, enables the connection between the end-watt-hour meter and the wireless data transmission. Equipped with the A/D conversion interface, it can realize the direct analog signal acquisition and transmission. Experiments show that the method is effective to improve the accuracy and convenience of power meter reading system.
