Abstract

The invention provides a testing system and a testing method for an electronic brake control unit. The testing system is externally connected with an upper computer which can be used for monitoring operation of the testing system, and comprises a power supply module which is used for providing electric energy to the testing system, and an interface testing module, a control testing module and a communication testing module which are electrically connected with the power supply module, wherein the interface testing module is arranged corresponding to an interface module of an electronic brake control unit; the control testing module is arranged corresponding to a control module of the electronic brake control unit; the communication testing module is arranged corresponding to a communication module of the electronic brake control unit; and the interface testing module, the control testing module and the communication testing module are connected through CAN bus. The testing system can realize overall port coverage, and the testing method is simple and convenient to operate and quick and complete in testing.

Description

technical field [0001] The invention belongs to an electronic brake control unit in a rail vehicle, and in particular relates to a test system for an electronic brake control unit. Background technique [0002] Electronic brake control unit (EBCU) is the core of the rail vehicle braking system, including power supply module, digital input and output module, frequency input and output module, analog input and output module, PWM input and output module, power drive module, fault judgment module And communication modules, etc., which can realize brake management, pressure control, signal acquisition, communication and other functions, and its reliability and safety have a huge impact on driving safety, so its testing is also particularly important. [0003] The existing EBCU test bench is mainly composed of industrial computer, data acquisition card, signal conditioner, pressure sensor, PLC, relay and other equipment, which requires professionals to operate, and the focus is on...
