Embodiment Construction

[0014] A high-precision dynamic weighing method, which is to fix the load cells at the four corners of the scale body, and the load cells located at the four corners of the scale body are respectively connected to the data processor, and the data processor changes the force of each point of the four corners of the scale body respectively. The analysis, real-time calculation of the position of the axle on the scale body, and accurate judgment of the wheelbase, number of axles, axle load, and total weight.

[0015] Such as Figure 1-3 As shown, the high-precision dynamic weighing instrument realizing the above method has a scale body 1 carrying a vehicle, and load cells 2 are installed at the four corners of the scale body 1, and the load cells 2 are respectively connected to the data processor. The four corners of the scale body 1 adjust the gap with the frame 5 through the horizontal limit screw 3 and the vertical limit screw 4, and the scale body has a length of 3.6-4.2 meter...

Abstract

The invention provides a high precision dynamic weighing method and a high precision dynamic weighing instrument and aims to overcome the problems of low weighing accuracy, axle loss and data loss existing in axle load truck scale of present road toll by weight. The four corners of a scale body adjust the gap between the scale body and a frame through a horizontal limit screw and a longitudinal limit screw to cause the movement of the scale body in horizontal direction to be limited within a certain range and keep vertical stress. Besides, the scale body is 3.6-4.2m long and 3.0-4.0m wide. The weighing method is realized as follows: weighing transducers are fixed at the four corners of the scale body, a data processor weighs the four corners of the scale body in real time, the instantaneous weight, instantaneous axle number (the axle number on the scale body) and the weight of each axle are analyzed and calculated in real time, and the principle of moments and mechanical method are applied to calculate the position and numbers of the axle and accurately judge the axle number and weight and the total weight.

Description

technical field [0001] The invention belongs to the technical field of metering, in particular to the improvement of a dynamic weighing instrument for highway weighing and charging. Background technique [0002] At present, the axle load meter for highway weighing toll generally adopts a scale body with a length of 0.8m, and the four corner sensors are connected in parallel to measure the change of the axle load by the overall force of the scale body, and the total weight of the vehicle is obtained by adding the weight of each axle. Due to the vibration of the vehicle, the change of the acceleration, the factors such as the artificially making the vehicle go in an S-shape, and the weight jumping, etc., the loss of the shaft and data will directly affect the invalidity of the weighing; the triple shaft of the large vehicle is the main load, and the length of the scale body is 0.8m. Due to the unevenness of the ground, the triple shaft cannot be accurately weighed, so the accu...
