The I / O acquisition module is used to collect the external I / O input status. The test main board includes a microcontroller unit, which can interact through serial port communication. The test main board includes an optocoupler input terminal, which is used to detect the power output status.

[0019] Through the setting and joint cooperation of the test mainboard, display module and CAN communication module, the microcontroller unit in the test mainboard is used to send test data to the brake control board through serial communication interaction and receive feedback. The door lock input status, relay action status, MOS action status, button action status and external power supply output status of the brake control board are successfully tested at the same time, which greatly saves detection time and reduces detection costs.

[0020] Working principle: When using this device, refer to Figure 2 As shown, you can follow the steps below in sequence:

[0021] When testing the door lock of the brake control board, the microcontroller unit of the test mainboard sends test data to the brake control board through serial communication interaction. After receiving the test data, the brake control board feeds back the door lock input status to the test mainboard. The test mainboard confirms the test data. If the test passes, the next test will be entered. The display module displays the test steps in real time. If it fails, the test will be stopped and the fault will be sent to the display module. The display module displays the fault code and content.

[0022] Based on the success of the above test, the microcontroller unit of the test mainboard sends test data to the brake control board through serial communication interaction. After receiving the data, the brake control board feeds back the relay status to the test mainboard. The test mainboard confirms the test data. If the test passes, it proceeds to the next test. The display module displays the test steps in real time. If it fails, the test is stopped and a fault is sent to the display module. The display module displays the fault code and content.

[0023] On the basis of the success of the above test, the microcontroller unit of the test mainboard sends the test data to the brake control board through serial communication interaction. After receiving the data, the brake control board feeds back the MOS status to the test mainboard. The test mainboard confirms the test data. If the test passes, it proceeds to the next test. The display module displays the test steps in real time. If it fails, the test is stopped and the fault is sent to the display module. The display module displays the fault code and content.

[0024] The brake power output port of the brake control board is externally connected to a contactor module, and the feedback point of the contactor module is connected to the optocoupler input terminal of the test mainboard. On the basis of the success of the above test, the test mainboard directly collects the input status of the I / O port through the I / O acquisition module to confirm the status of the brake power output port of the brake control board. If the test passes, the next step of the test will be entered, and the display module will display the test steps in real time. If it fails, the test will be stopped and the fault will be sent to the display module, and the display module will display the fault code and content.

If the test passes, it proceeds to the next step, and the display module displays the test steps in real time. If it fails, the test is stopped and the fault is sent to the display module, and the display module displays the fault code and content.

[0026] It should be noted that the various test data in the above process are existing technologies and will not be described in detail here. When the above tests are successful, the test mainboard sends a test completion instruction to the display module, and the display module displays that the test is successful and the test is completed.
