Abstract

The invention provides a testing device which comprises a tester, a signal conditioning module, a VXI bus instrument, a master control computer and standard test interfaces. The master control computer is connected with the tester, the signal conditioning module and the VXI bus instrument through corresponding programmable interfaces, and the tester, the signal conditioning module and the VXI bus instrument are connected with tested objects through the standard test interfaces. The automatic testing device is simple to operate and accurate in measurement, reduces influence of human factors, guarantees high testing efficiency, and is safe and reliable in a testing process.

Description

Technical field [0001] The invention relates to a testing device, in particular to an automatic testing device. Background technique [0002] The train network control system is composed of a microprocessor-based distributed intelligent control and diagnosis system connected through a network, and performs the control, monitoring and diagnosis functions of the entire train. The train's traction system control unit includes the traction control unit TCU (Traction Control Unit) and the central control unit CCU (Central Control Unit). TCU and CCU are two extremely important devices in the train network control system. In rail transit rolling stock, TCU and CCU generally adopt a chassis structure, composed of boards with various functions, and are integrated and connected through a backplane bus. According to the different needs of the actual project, TCU / CCU can form a new combination and realize its functions by extending the function board. [0003] The current TCU and CCU produc...
