With the development of rural power market in our country, how to improve the operation more correctly and timely of power quantity collection, transmission and processing becomes a problem. The requirement of equipment in power quantity collection needs new and higher demands. The advantage of using dual-port RAM and main-spare CPU structure, when main CPU running, spare CPU supply monitoring of main CPU status messages, once main CPU break down, spare CPU could instead of main CPU completely. This paper introduces collectivity design in flow chart, hardware design include theory and application in detail. Using dual-port RAM to communicate between the main and spare CPU not only make sure the transmission efficiency, good anti-jamming performance, improve the speed of disposal, but also reduce the costs, making the operation of rural power network more security, economy and reliability. In rural power terminal system of power quantity collection has broad application prospects.
