Abstract

The embodiment of the invention discloses a vehicle-mounted controller test method, device and system. The method comprises the steps of determining a test input voltage, a test load current and a power voltage for a to-be-tested logic connection element in a vehicle-mounted controller; based on the test input voltage and the power supply voltage, applying an input signal to the vehicle-mounted controller, and obtaining an output signal of the vehicle-mounted controller under the input signal; generating a test signal according to the output signal and the test load current; and determining atest result of the logic connection element according to the test signal and a preset standard test signal. Therefore, the vehicle-mounted controller can be tested.

Description

technical field [0001] The present application relates to the technical field of device testing, in particular to an on-board controller testing method, device and system. Background technique [0002] As an important control device in high-speed maglev trains, the on-board controller is usually used to receive control commands such as lifting commands and braking and parking commands issued by the train control system, and transmit these control commands to the levitation controller, guidance system, etc. controller, brake controller, etc.; in addition, the on-board controller is also used to receive the train status signal collected by the relevant status signal acquisition device, and feed back the received train status signal to the train control system. It can be seen that the on-board controller plays an extremely important role in the high-speed maglev train as an intermediate device between the transfer control command and the status signal. [0003] However, there ...
