Embodiment Construction

[0027] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings. Such as figure 1 As shown, it is an axle load detection system for dynamic vehicle weighing according to an embodiment of the present invention. The system includes: a weighing platform (not shown in the figure), used to carry passing vehicles to be weighed; a data acquisition unit, used It is used to collect the axle load signal and axle type signal of each axle of the vehicle being weighed; the weighing platform and the data acquisition unit form an axle load data acquisition device. The system also includes: a data control unit (such as a single-chip microcomputer, a PC, etc.), and the data control unit includes: a data generating unit, which is used to generate the dynamic weighing data of the shaft and the shaft according to the shaft load signal and shaft type signal of each shaft. Type data; effective data acquisition unit, used to p...

Abstract

The invention provides a dynamic vehicle weighing method and system; all shafts of the vehicle to be weighed subsequently drive pass a weighing platform, wherein, the method includes the following steps: the shaft load signal and the shaft type signal of all the shafts of the vehicle to be weighed are collected; the dynamic weighed data and shaft type data of the shafts are generated according to the shaft load signal and the shaft type signal of the shafts; the dynamic weighed data is processed to obtain and weigh effective data; trigonometric function approximation processing is conducted on the shaft weight effective data to obtain the shaft weight benchmark data and the revised data; the shaft weight is obtained according to the shaft type data and the shaft weight benchmark data and the revised data. The invention is used to solve the problem of dynamic weighing of vehicles passing the weighing platform at medium and low speed, and provide weighing schemes meeting the weighing precision requirement for different vehicle types.

Description

technical field [0001] The present invention relates to the weighing technology, in particular to the technology of weighing detection of vehicle overloading and exceeding the limit and the technology of charging by vehicle weight, specifically a dynamic vehicle weighing method and system. Background technique [0002] At present, the dynamic weighing system is widely used in the weighing system of freight vehicles such as highways, mines, and ports, and plays an important role in traffic management, over-limit and overload control, and import and export supervision. [0003] Chinese utility model patent 94246532.6 discloses a kind of all-electronic type axle load dynamic weighing platform, and this dynamic weighing platform adopts the axle load weighing method to weigh the vehicle weight. When the car slowly passes the weighing platform, the load cell installed in the weighing platform converts the axle load into an electrical signal, and forms a full electronic weighing sy...
