  • With the STM32F107RB as the controller,and the scheme of passive pillar type as the design scheme,the data acquisition system of electronic current transformer was designed.The signal was transmitted to low voltage side through the cable to improve the reliability of electronic circuit.On the grounds of multi-channel data acquisition,integrated chip of LMP2014MT was taken as amplifier to amplify the small signal by different gains,so that the quantification error of AD conversion was reduced to improve the precision of the acquisition.Hardware design used powerful STM32 to control AD conversion and then to transmit signal to merging unit.This system can simplify electronic circuit and improve the precision while strengthening the stability of circuit.
