Method for improving accuracy of full vehicle type continuous vehicle-following weight calculation equipment as well as high-accuracy full vehicle type continuous vehicle-following weighing implementation method and system

Abstract

The invention provides a method for improving accuracy of full vehicle type continuous vehicle-following weight calculation equipment as well as a high-accuracy full vehicle type continuous vehicle-following weighing implementation method and system. The core technology is that a method integrating modular integrated weighing systems and dynamic fitting weighing modules is designed, and weighing and error correction of a full vehicle are realized through dynamic fitting of the weighing modules. The core concept lies in that a continuous vehicle-following weighing mode is automatically developed into a full vehicle weighing mode, vehicles are subjected to continuous vehicle-following weighing in the modular integrated weighing systems arranged in array, and the requirements of highway weighing equipment for high accuracy and the high efficiency are met. The core concept of the novel method lies in that the continuous vehicle-following weighing mode is automatically developed into a 'one pole, one scale' full vehicle weighing mode, the weighing influence of a front vehicle on a rear vehicle is eliminated through the modular structure of the system, each vehicle repeats the weighing process of the first vehicle, the weighing accuracy of one scale for one vehicle is guaranteed, and the advantage of high efficiency of continuous vehicle-following passing is realized.

Description

technical field [0001] The invention belongs to the technical field of dynamic weighing, and is especially suitable for popularization and application in the field of toll roads. Background technique [0002] Vehicle-based weighing equipment is generally used in the field of road weight toll collection, and the vehicle-based weighing equipment has gradually become the main equipment in the industry due to its high measurement accuracy. [0003] At present, the weighing mode that can guarantee the whole vehicle weighing equipment is "one pole, one vehicle", but the weighing interval of this mode is long, which seriously affects the traffic efficiency of toll lanes; the industry urgently needs to improve the efficiency of toll traffic, Realize the "continuous follow-up" weighing mode of the whole vehicle. [0004] In order to solve the disadvantage of the low traffic efficiency of the weighing mode of the "one pole, one vehicle" weighing equipment, it is generally adopted to ...

AI Technical Summary

Problems solved by technology

The system judges and calculates the total weight of the vehicle through factors such as the upper and lower scales of each axle of the vehicle, the displacement of the axle, the weight change of the front vehicle and the current weight change of the weighing system. The calculation process introduces the axle load of the vehicle to participate in the calculation. Uncertainty, the measurement accuracy of the system is greatly affected

[0005] Based on the above existing technologies, expressway weighing equipment has been unable to solve the problem of vehicle weighing equipment that can not only ensure measurement accuracy but also improve traffic efficiency.
