These devices usually include strain gauge sensors, pressure sensors or acceleration sensors, which are installed on a fixed rod or on one side of the anti-skid device, such as on the ground, to capture and record the changes in braking force in real time. Since the root of the fixed rod is not firmly connected to the ground, it tilts during the measurement process, resulting in low accuracy of the measurement data and poor stability.

Since the sensor is arranged on the measuring module 1 composed of the crossbar assembly 101, the first vertical rod assembly 102 and the second vertical rod assembly 103, it does not need to be fixed in contact with the ground. If the rigidity of the measuring module 1 is sufficient, the pressure sensing assembly 104 can be prevented from tilting relative to the brake rail 6, thereby improving the accuracy and stability of the braking force data detection, thereby accurately reflecting the stable performance of the braking force of the parking device.
