On remote automatic meter reading system based on GPRS technology

In order to precisely collect realtime data of Watt-hour meters, this paper presents a wireless automatic meter reading system based on GPRS technology, which is permanently online, high-speed, low power consumption and widely used. In hardware system, it mainly introduces a GPRS module's interface concentrator, whose core component is the TMS320F2812 chipset produced by the US's TI company. Whereas in software system, it addresses the main station with a systematic analysis management software. This system has a promising market because of its simple building, low operating cost, reliable performance, high automation, and quick investment return.
