Gprs-based Power Remote Meter Reading System Design And Application

The communicatiaon of power system is an indispensable important prat of power system, it is the foundation to realize the power grid dispatching and the modernization management automation. With the rapid development of modern electric communication technology and the use of various communication technology in power system, the application based on GPRS power long-distance meter reading system is proposed. GPRS communication technology with its high transmission rate, relative low connection fee, access time is short, etc advantages become wireless communication network of choice for power.This paper mainly designed the hardware structure of GPRS power of long-distance meter reading system based on RS485. Watt-hour meter operating data acquisition wireless terminal is directly connected to the electric energy meter by RS485 interface, the collected data of watt-hour meter are all transmitted to power distribution center Meanwhile, watt-hour meter data acquisition wireless terminal can also transmit the remote control instructions of power distribution center to the to the control module of watt-hour meter.This paper studied the software and hardware composition, system plan and related products characteristics of GPRS power long-distance meter reading system integration. In comply with relevant standards this paper discussed the realization of function requirements on GPRS long-distance meter reading system. And this paper introduces the realization of the RS485 connection between GPRS watt-hour meter data acquisition wireless terminals and watt-hour meters, proposes its common bus fault processing.The power long-distance meter reading system based on GPRS to realize integrating copy meter is feasible, it will represent the automatic meter reading technology development and application of new trend. Its good real-time performance, high speed of data transmission, remote metering range, its advantages, construction of low cost for domestic vast, geographical conditions the complex and varied circumstances.To provide real-time fast, accurate monitoring data to the power supply enterprise and internal cost accounting for marketing analysis, it will be widely used in the automation of power system.
