| Abstract: | According to the analysis demand of electric power quality in power supply system of electrified railway, a data acquisition equipment with wireless communication interface for electric power signal is designed. In the system, high-voltage and low-voltage mutual inductors are applied to obtain the analog signal. In order to advance the performance of acquisition and control circuit, double CPU (Center Processing Unit) structure is adapted. Host circle based on ADSP (Analog Digital Signal Processor) realizes high-speed acquisition, signal processing and initial data analyzing, while the assistant circuit based on MCS-51 realizes the functions such as communication, man-machine interface, and so on. |
