Based On GPRS Applied Research On Power Distribution Load Monitor Terminal System

After the national promulgation "the People's Republic of China Electric power Law" implements the implementation, the electric power takes one kind of commodity to enter the market, accepts the user the surveillance and the choice, to electric power supply power cut influence pursue electric power experience's responsibility. Along with high-tech and the precision assembly to the electrical energy quality requirement also along with it enhancement, the distribution network power supply reliability already was the subject matter which the electric power operator must consider. This article in view of the present Guangdong Province electric power market's present situation, proposed one kind and uses the GPRS (General Packet Radio Service) mailing address based on the ARM (Advanced RISC Machines) control system the power distribution monitor terminal plan. This plan has the structure to be compact, characteristics and so on low cost. Now the Manufacturer is carrying on drifts net the experiment.This article introduced the ARM characteristic and the system structure simply. According to the related literature, summaried many kinds of mailing addresss which the present electrical power system appears, elaborated the GPRS rationale in detail. This article elaborated the Huffman code with emphasis in the overtone transmission application. Has given the description total design proposal, and has carried on the analysis to the part code process.And makes the actual test, discovered after using the Huffman code, increased transmission overtone highly effective. This article also with emphasis narrated the superior machine system's design process, including the database data processing process, undergoes the actual test, the discovery design superior machine system safety reliability is high. Then this article has carried on the analysis to the power distribution terminal quality and the performance, including the ARM processor system, communications channel's reliability, time analysis. Finally this article analyzes this power distribution from technical economy's angle to shoulder the terminal product the prospect.
