A Low Cost Design of the Rural Intelligent Meter Reading System

Analysis of the current use of rural electricity meters, and according to the situation of economic development in rural areas of China, to the greatest extent to reduce costs as the goal, intelligent remote meter reading system is presented which is applicable to China's rural areas. The system is composed of electric energy meter, collector, concentrator, the remote control center. Between collectors and concentrators use low voltage power line carrier communication, concentrator through the GSM network and remote control centre for internet. The collector and concentrator use AT89C52 as control chip, which reduces the system cost.
