There is a difference, and then judge whether the instrument is damaged. As shown in Figure 2, the working process of the tachometer and speedometer detection unit is: turn on the automatic detection mode, and the detection of the tachometer and speedometer will start automatically. operation of the meter and speedometer. In the automatic detection mode, if the tachometer or speedometer cannot indicate according to the preset parameter mode or has other abnormal phenomena, it means that the instrument indication is inaccurate or has been damaged; otherwise, it means that the tachometer or speedometer is normal. By pre-setting the input parameters of the sensor corresponding to the tachometer or speedometer, and comparing the automatic detection phenomenon with the phenomenon after starting the engine, the inspector can immediately make a judgment whether it is a problem with the instrument or the input signal of the corresponding sensor, which is convenient, fast and targeted Solve problems proactively.

If there is a difference, it means that the meter indication is inaccurate or has been damaged. Otherwise, it means that the fuel gauge or water temperature gauge is normal. After all the tests are completed, the processing module will display the results on the LCD screen. For example, the first digit of the displayed data can be preset to indicate the tachometer, the second to indicate the speedometer, the third to indicate the water temperature gauge, and the fourth to indicate the fuel. The meter, and the set value of 0 means it is normal, and 1 means it is damaged, so that the user can easily judge which meter is damaged by observing the monitoring result data on the LCD screen.
