Guide brackets 61 are further arranged on two sides of the pressure sensor assembly 4, and the pressure sensor assembly 4 moves up and down along the inner walls of the guide brackets 61 when moving. As shown in fig. 4, the pressure sensor assembly 4 is symmetrically disposed four along both sides of the quartz bar sensor assembly 1, and the arrow indicates the vehicle passing direction.

As shown in fig. 2, in an initial state (i.e. no detection vehicle passes through), the pressure sensor assembly 4 jacks up the base bottom plate 221, so that a gap is left between the upper end surface of the quartz bar sensor assembly 1 and the inner wall of the upper end of the base recess 223, and the use performance of the quartz bar sensor assembly 1 is affected by the long-time static compression state due to the suitability of the quartz bar sensor assembly 1 for dynamic detection, so that the compression surface of the upper end of the quartz bar sensor assembly 1 is separated from the inner wall of the upper end of the base recess 223, i.e. when no vehicle detection is performed, the weight of the connecting seat 2 is borne by the pressure sensor assembly 4. The excessive gap value can cause the acceleration distance of the downward movement of the base bottom plate 221 to increase when the vehicle passes through and presses down the base bottom plate 221, and cause the impact force to increase when the inner wall of the upper end of the base recess 223 contacts with the upper end surface of the quartz bar sensor assembly 1, so that the error is increased, the gap value is set to be 1-3mm, and corresponding compensation can be set in the weighing system.
