The Design And Implementation Of Remote Electricity Meter Reading Concentrator System

With the improvement of China’s economic and technological level and thecontinuous improvement of the power system, the original manual meter reading waymore and more can not meet the needs of the development of the power system, powerremote automatic meter reading system because of its advantages of high efficiency, lowerror rate, arises at the historic moment. In recent years, information acquisition projectof national power system (construction project of automatic meter reading system) hasbeen in full swing, the concentrator as the core equipment of the automatic meterreading systems, market demand is huge, therefore, its research value is bigger also.This thesis on the present situation and trend of development of the automaticmeter reading technology at home and abroad made a detailed analysis, then through theintroduction of the composition of automatic meter reading system, which leads to theconcentrator in the important function of the automatic meter reading system, thenexpounds the working principle of the concentrator through the understanding of thefunction and working principle of the concentrator, in combination with theconcentrator of tendering requirements related to the national grid, the system demandanalysis, and according to the demand analysis of the concentrator system software andhardware design scheme of research, finally determined by high performance ARMchips as the main control chip, telephone (MODEM) and low voltage power carrierwave communication and RS-485bus as the main communication solutions. Throughthe concentrator is part of the software and hardware design in detail, finally designed asuitable market the actual cable carrier to concentrator. After testing, basic cansuccessfully achieve the function of the system is expected.The realization of this system has changed the traditional manual meter readingmethod is time-consuming and laborious, can effectively reduce the labor intensity ofthe meter reading staff, can remain within doors can complete user smart meter datareading, at the same time can also be caused by human factors error of meter reading toa minimum, so as to improve the power company’s working efficiency, has a goodapplication prospect good.
