Description

Technical Field

[0001] This utility model relates to the field of sensor testing equipment technology, and in particular to a sensor dual-station testing platform. Background Technology

[0002] Modern cars' ABS systems are equipped with electromagnetic induction wheel speed sensors, which can be installed in the final drive or transmission. They come in two basic forms: active and passive. Wheel speed sensors are used to measure the rotational speed of a car's wheels. Wheel speed information is essential for modern cars. Vehicle dynamic control systems, electronic stability programs, anti-lock braking systems, and automatic transmission control systems all require wheel speed information. Therefore, wheel speed sensors are one of the most critical sensors in modern cars.

[0003] ABS sensor testing stations are used to test the quality of sensors. They are usually used to test individual sensors. When it is necessary to test and analyze different sensors, the test data can only be recorded one by one before comparison and analysis. It is not convenient to use because the monitoring data cannot be displayed on the screen at the same time for comparison and analysis.

[0004] Therefore, it is necessary to provide a dual-station sensor test bench to solve the above-mentioned technical problems. Utility Model Content

The motor 6 is then started to drive the turntable 7 and the rotating wheel 8 to rotate through the insertion holes 461 of the two mounting plates 46. The first sensor body 9 and the second sensor body 10 are respectively inserted into the inner, so that the detection heads of the first sensor body 9 and the second sensor body 10 are located on the outer side of the outer circumference of the rotating wheel 8. The rotation speed signal of the rotating wheel 8 is transmitted to the display device 11 through the detection head. The data signals transmitted back by the first sensor body 9 and the second sensor body 10 are displayed through the first display screen 12 and the second display screen 13. The detection performance signals of the first sensor body 9 and the second sensor body 10 can be observed intuitively, which is convenient for users to compare and analyze. The detection is convenient and fast, the analysis and comparison are convenient, and the testing efficiency is high.
