Problems solved by technology
Sometimes, certain factors may lead to changes in the data display of the instrument. In order to ensure timely readings, it is often necessary to send more than one staff to operate at the same time and record at the same time.
This has resulted in low work efficiency, large dispersion of test data, and reduced accuracy of test results.
More importantly, when performing some action time tests, the action time may be at the ms level, and it is almost impossible for the staff to accurately complete this test manually.
Therefore, my country's current comprehensive testing and fault diagnosis system for electrical equipment of urban rail transit vehicles is still at a very backward stage. The maintenance process of electrical equipment is in a state of blindness

Embodiment 1
[0029] The electrical maintenance center of the upper system of each subsystem, the electrical maintenance center is responsible for summarizing the test data of the bottom detection subsystem, and making a more detailed diagnosis of the test results through the upper fault diagnosis host, and establishing the status diagram of the vehicle electrical equipment maintenance. The underlying equipment detection subsystem is responsible for on-site maintenance and testing of various electrical equipment, and uses the local area network (including wired LAN and wireless LAN) of the maintenance base to report the test data and maintenance status to the electrical maintenance center.

The invention discloses a detection system of a set of electrical equipment of an urban rail vehicle. The detection system comprises a detection sub-system of a traction motor, a detection sub-system of a circuit breaker, a detection sub-system of a driver controller, a detection sub-system of a relay / a contactor, a detection sub-system of a magnetoelectric velocity sensor and a detection sub-system of a voltage transformer / a current transformer; and the detection system of the electrical equipment of the urban rail vehicle can completely detect the whole electrical equipment of the urban rail vehicle, and has significant meanings of reducing equipment faults and guaranteeing vehicle safety.
Description
technical field [0001] The invention relates to a detection system for electrical equipment of urban rail vehicles. Background technique [0002] Urban rail vehicles mostly use distributed power technology, so each urban rail vehicle is equipped with a large number of electrical equipment, such as traction motors, driver controllers, high-speed circuit breakers, and a large number of electrical equipment such as relays, contactors, and automatic switches. . [0003] According to the survey, the electrical equipment maintenance of several large-scale urban rail transit vehicle maintenance bases in my country still adopts the old methods of manual reading, manual recording and manual operation. The test data is compiled into a test report after manual processing. Sometimes, certain factors may cause changes in the instrument data display. In order to ensure timely readings, it is often necessary to send more than one staff to operate and record at the same time. This has res...
