Embodiment 1
[0058] Such as Figure 4 As shown, the vehicle overload detection method specifically includes the following steps:
[0059] Step 1: Collect the axle load signal, vehicle speed signal and axle number; save the axle load signal from zero point to the limit value in the first storage space, and save the axle load signal exceeding the limit value in the second storage space;
[0060] The specific process of step 1 is:
[0061] When the load cell does not detect the axle load signal, the axle load signal (voltage signal) collected by the axle load sensor is digitally filtered and stored in the first storage space. If the first storage space is full but the axle load sensor signal is still If the limit value is exceeded, the newly collected axle load signal will be overwritten and saved from the initial position of the first storage space;
[0062] When the latest 3 consecutive axle load signals collected by the load cell are higher than the limit value, it is considered that the...
Embodiment 2
[0083] Such as Figure 1-4 As shown, this implementation provides a vehicle overload detection system, including: a piezoelectric quartz sensor, a piezoelectric film sensor, a ring-shaped ground induction coil and an output signal processing circuit respectively connected to a single-chip microcomputer;
[0084] The piezoelectric quartz sensor is installed at the front end of the incoming vehicle direction, and the piezoelectric film sensor is installed at a position with a set distance from the piezoelectric quartz sensor (for example, the distance is 1.0-1.5m), and away from the incoming vehicle direction; the quartz sensor is perpendicular to the driving direction , in order to ensure that the measured speed error is as small as possible, the parallelism of the sensor is less than 4mm; the ground sense coil is installed at a position 0.3-1.0m behind the piezoelectric film sensor.

Embodiment 3
[0113] This embodiment provides a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the steps in the vehicle overload detection method described in the first embodiment above are realized.
[0114] The vehicle overload detection method implemented in this embodiment obtains the effective axle load below the limit through iterative collection and storage in a fixed storage space, which can not only ensure that the working efficiency of the dynamic weighing system meets the requirements of real-time detection, but also ensure that the collection axle Focus on data integrity and improve detection accuracy.
[0115] At the same time, the calculation method of the two integral values proposed by the vehicle overload detection method implemented in this embodiment and the comparison processing of the calculation results can solve the deviation of the measurement accuracy caused by the vehicle running at an ultra-lo...
