Then the water enters the diversion pipe 20 through the connecting pipe 19, and then is diverted from the diversion pipe 20 to the inside of the water spray pipe 21. Then the water is sprayed out as atomized water vapor through the atomizing nozzle 22, so that the interior of the detection chamber 5 is filled with moisture. When water accumulates inside the detection chamber 5, the water will be discharged into the water tank from the leak hole, thereby realizing water recovery.

[0037] The device is used to diagnose the detection method of the automobile electronic control module. The steps are as follows:

[0038] Step 1: Place the electric control module 15 on top of the vibration plate 9, then turn the handle to drive the screw 11 to rotate. The rotation of the screw 11 drives the threaded plate 10 to move. The movement of the threaded plate 10 drives the first clamping plate 13 to move accordingly. The first clamping plate 13 moves accordingly to drive the connector 17 to plug into the connector of the electric control module 15. At the same time, the limit plate 14 is located on the mounting plate of the electric control module 15, and cooperates with the second clamping plate 16 to clamp the electric control module 15. Then close the door panel 2.

[0039] Step 2: The controller 4 controls the water pump 23 to start and transport the water in the water tank to the inside of the connecting pipe 19 through the circulating water pipe 24. The water then enters the shunt pipe 20 through the connecting pipe 19, and is then diverted from the shunt pipe 20 to the inside of the water spray pipe 21. The water is then sprayed out as atomized water vapor through the atomizing nozzle 22, so that the interior of the detection chamber 5 is filled with moisture. The humidity value of the detection chamber 5 is detected by the humidity sensor and transmitted to the interior of the controller 4. The controller 4 controls the start and stop of the water pump 23 according to the humidity value detected by the humidity sensor, so that the humidity value inside the detection chamber 5 is maintained at 90% to 98%. At the same time, the heater 18 is started to heat the detection chamber 5. The temperature inside the detection chamber 5 is detected by the temperature sensor and transmitted to the controller 4. The controller 4 controls the start and stop of the heater 18 through the temperature sensor, so that the internal temperature of the detection chamber 5 is maintained at 40°C, thereby realizing the moisture-proof property of the electronic control module 15 stored for a long time in a high humidity environment.

[0040] Step 3: At the same time, in the high altitude environment, the controller 4 controls the vibration machine 12 to start, the vibration machine 12 drives the vibration plate 9 to vibrate, and the vibration of the vibration plate 9 drives the electronic control module 15 to vibrate;

[0041] Step 4: During the moisture and vibration protection of the electronic control module 15, the signal simulator inside the controller 4 simulates different sensor signals. Taking the automobile oxygen sensor as an example, when the oxygen signal is input into the electronic control module 15, the electronic control module 15 responds to the oxygen sensor signal and stores the oxygen sensor signal. The data acquisition module reads the code of the oxygen sensor signal inside the electronic control module 15 through the connector 17, compares the code with the corresponding code in the data, and determines whether the electronic control module 15 can respond accurately. When the codes do not match, it is diagnosed that an error has occurred in the electronic control module 15, and then the controller 4 transmits the diagnostic information to the screen 3 for display.

[0042] The signal simulator then simulates an air flow signal and inputs it into the electronic control module 15 for testing. If an error message is displayed after the test, the staff will then test the corresponding electronic components of the electronic control module 15 based on the error message to determine whether the electronic components are damaged due to vibration or moisture has entered the electronic control module 15, causing problems with the electrical components, or whether the problem is with the electronic components themselves.

[0043] Step 5: The signal simulator simulates an erroneous oxygen sensor signal and transmits it to the electronic control module 15. The electronic control module 15 generates a corresponding fault code. The signal simulator then simulates a correct oxygen sensor signal and transmits it to the electronic control module 15. The electronic control module 15 then clears the erroneous code. The data acquisition module then reads the code from the electronic control module 15, verifies the code information with the oxygen fault code in the database, and diagnoses whether the electronic control module 15 has implemented the fault diagnosis system self-test. The controller 4 then transmits the diagnostic information to the screen 3 for display.

At the same time, the heater (18) is started to heat the detection chamber (5). The temperature inside the detection chamber (5) is detected by the temperature sensor and transmitted to the controller (4). The controller (4) controls the start and stop of the heater (18) through the temperature sensor, so that the internal temperature of the detection chamber (5) is maintained at 40°C, thereby realizing the moisture resistance of the electronic control module (15) stored for a long time in a high humidity environment; Step 3: At the same time, in the high-altitude environment, the controller (4) controls the vibration machine (12) to start, the vibration machine (12) drives the vibration plate (9) to vibrate, and the vibration of the vibration plate (9) drives the electric control module (15) to vibrate; Step 4: During the process of moisture-proofing and vibration-proofing the electronic control module (15), the signal simulator inside the controller (4) simulates different sensor signals. When the oxygen signal is input into the electronic control module (15), the electronic control module (15) responds to the oxygen sensor signal and stores the oxygen sensor signal. The data acquisition module reads the code of the oxygen sensor signal inside the electronic control module (15) through the connector (17), compares the code with the corresponding code in the data, and determines whether the electronic control module (15) can respond accurately. When the codes do not match, it is diagnosed that the electronic control module (15) has an error, and then the controller (4) transmits the diagnostic information to the screen (3) for display. Then, the signal simulator simulates the air flow signal and inputs it into the electronic control module (15) for testing. When an error message is displayed after the test, the staff will then test the electronic components corresponding to the electronic control module (15) based on the error message to determine whether the electronic components are damaged due to vibration or moisture has entered the electronic control module (15), causing problems with the electrical components, or whether there are problems with the electronic components themselves. Step 5: The signal simulator simulates an erroneous oxygen sensor signal and transmits it to the electronic control module (15). The electronic control module (15) generates a corresponding fault code. The signal simulator then simulates a correct oxygen sensor signal and transmits it to the electronic control module (15). The electronic control module (15) then clears the erroneous code. The data acquisition module then reads the code from the electronic control module (15), verifies the code information with the oxygen fault code in the database, and diagnoses whether the electronic control module (15) has achieved a self-check of the fault diagnosis system. The controller (4) then transmits the diagnostic information to the screen (3) for display.
