Design of energy consumption monitoring system for metro vehicle

The design requirements, design scheme and structural features of energy consumption monitoring system for metro vehicle are presented in this paper. Through type selection of component, optimization design of electro circuit and reasonable routing of albumen plate,collection and metering problems of DC electric energy for metro vehicle are solved mainly. The produetions have been verified from test and loaded on vehicles for operation successfully. The results show that the structure and performance of the energy consumption monitoring system are reasonable,the precision is lofty and EMC is excellent. It satisfies the requirements of electrical energy collection, retention of date, display and communication of metro vehicle.
