Power System Based On Gprs Wireless Set Reading System And Application

With the progressive development and application of GPRS wireless communications and other modern technology, Wireless communications network reliability and efficiency has been widely recognized by society . Energy Measurement and Automation of Power Marketing Automation is an important element, Electricity customers metering data through remote ARMS (Automatic Meter Reading System) automatic transmission and management accounting, At the same time consumption of electricity customers to monitor analysis for Power Marketing Automation to provide timely and accurate data base, Automated Meter Reading this management system is widely used in power enterprise marketing automation and electricity management accounting major clients, it will represent the automatic meter reading technology development and application of the new trend. This paper introduces a communications network based on GPRS power monitoring system development and application of the theory.This system is made up of four parts: data gathering, data communication , data processing analysis and control. This system makes use of several means , such as the SMS of GPRS network, voice channel ,etc. to realize the " four distant " function of the power system. This system can accept and record the phase voltage , electric current , active power , reactive power , power factor , the time of voltage exceeding the limit , net loss statistic of the locale equipment. It can also inspect and control the switch, alarm the exceeded voltage and electric current , calculate the net loss. This article mainly introduces the composition of the monitoring system ,GPRS communication module, communication DLL(dynamic link library) of backstage supporter interface and GPRS backstage supporter software of monitoring system and Field application.The system also consider a national communications statute and the Statute of enterprises, The historical database can be visited by some kind of tools such as Excel , Foxpro directly with ODBC (open database is joined ) . Backstage supporter's management software is designed on Windows 9x software platform., Backstage supporter management software transfers the function of DLL (dynami link library) to finish various kinds of data gather and control the function It also has other functions such as authority management , data inquiry , curv drawing , typing the report and so on .With the development of automatic technology, computer technology and I technology, the cost will be lower, the communication will be more reliable b the use of GPRS public network to carrying on remote data transmission. Th monitoring system based on GPRS will have a more widely applications an increasingly perfect..
