Embodiment Construction

[0038] Such as Figure 1-6 As shown, a method for calibrating dynamic weighing accuracy uses a load cell group to collect vehicle weight signals. The load cell group consists of N rows arranged at uniform intervals along the direction of travel of the vehicle, and each row includes Symmetrical left and right load cells; N is a natural number, and the load cells in the Nth row are N left and N right;

[0039] The method for calibrating dynamic weighing accuracy includes the following steps:

[0040] S1. Sensor calibration:

[0041] S11. Select a small car with a weight of G to drive through the left side of the lane at a speed V, repeat 20 times, get 20 sets of data from the left load cell of N and take the average value, and get the average value of each load cell to be left ZN ;

[0042] S12. Taking ZN left as the weighing reference value and ZN+1 left as the adjustment value, then the adjustment coefficient of N+1 left is:

[0043] UN+1 left=(ZN left / ZN+1 left);

[0044...

Abstract

The invention provides a method for calibrating dynamic weighing precision. A weighing sensor group is adopted for collecting a vehicle weight signal, wherein the weighing sensor group is composed ofN rows of weighing sensors which are uniformly arranged at intervals in an advancing direction of a vehicle, and each row of the weighing sensors comprises the left and right weighing sensors which are arranged on the two sides of a lane and are symmetric; and N is a natural number, and the Nth row of the weighing sensors is Nleft and Nright. The method for calibrating the dynamic weighing precision comprises the following steps: S1, calibrating the sensors; S2, calibrating sensor data; S3, calibrating the total weight of the vehicle; and S4, obtaining the actual total weight of the vehicle. The dynamic weighing precision can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of dynamic weighing, and in particular relates to a method for calibrating dynamic weighing accuracy. Background technique [0002] The traditional dynamic weighing algorithm only relies on the signal generated by a single sensor for denoising and processing to obtain the weighing data; and usually obtains the weighing data after a correction coefficient is given according to the entire lane. Although this method can calculate the weighing data, the reliability of the calculation accuracy is not good due to the inconsistency of the sensor itself, road conditions, and grinding conditions. In order to effectively improve the dynamic weighing accuracy, a calibration dynamic Precautions against weighing accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a method for calibrating dynamic weighing accuracy to solve the problem that the traditional dynamic weighing alg...
