基于DSP+ARM的直流充电桩高精度电能表的研究
Research and Application of Electric Energy Metering Based on DSP+ARM for the DC charging of Electric vehicle
According to the real situation of lack of electric energy metering system based on embedded platform to solve the problem of poor stability and low metering accuracy of electric energy metering device during CHARGING of DC charging piles of electric vehicles., this paper introduce a data monitoring system which based on embedded platform. This system adopts modularization design which includes signal collecting, DSP signal processing and ARM processing platform. The accuracy of data counting is apparently improved because the data collecting unit adopts 16 channels synchronous sampling; system can collects, counts, displays and stores plant operation data for system analysis effectively, since combination of DSP and ARM. This solution is useful to design monitoring system which will be more portable, lower cost and energy consumption.
