Fixed type vehicle dynamic weighting system

Abstract

The present invention discloses a stationary type moving vehicle weighing system including a picture pick-up system, a high-speed pre-detecting subsystem for the dynamic weighing, a low-speed and high-precision weighing executing subsystem and an alarming system of the information board. The high-speed pre-detecting subsystem consists of a high-speed angle block weighing sensor, a data processing unit, an automatic vehicle classifying device, a floodlight and the first computer; the low-speed and high-precision weighing executing subsystem consists of a weighing platform, a data processing unit, an automatic vehicle classifying device, a right of way signal lamp and a second computer. The system pre-detects the whole weight and the shaft weight of the vehicles passing and filters the vehicles that may break the rules which are guided into the detecting area and are performed a second detecting by the low-speed and high-precision weighing system. The the vehicles that may break the rules are filtered automatically when the vehicles are running and the real weight of the vehicles are obtained by providing a signal processing method of combining a small wave converting and a hereditary arithmetic and eliminating the high and low frequency interference and by performing the ARX model identification of the processed signals.

Description

technical field [0001] The invention relates to the technical field of vehicle dynamic weighing, in particular to a fixed vehicle dynamic weighing system. Background technique [0002] Overweight and overloaded transportation of vehicles has caused a series of negative effects: damage to road infrastructure, disruption of the transportation market, a large loss of state fees and taxes, frequent traffic accidents, hindering the structural adjustment of the automobile manufacturing industry, and polluting the environment along the road. Over-limit and overloading needs to be dealt with comprehensively. In addition to speeding up legislation, strengthening law enforcement, and carrying out in-depth and extensive education, it is an indispensable technical means to be equipped with advanced and applicable vehicle dynamic weighing systems. Road vehicle dynamic weighing (Weight in Motion, referred to as WIN), refers to the measurement of the axle load and vehicle weight of the veh...

AI Technical Summary

Problems solved by technology

Engineering practice shows that in the environment of vibration and electromagnetic interference, there is a phenomenon that the software runs out of programs, which affects the reliability of the entire weighing system.

On the other hand, the high-speed dynamic signal output by the load cell is a typical short-course non-stationary signal, and obtaining the real weight of the vehicle from the short-course non-stationary signal is inseparable from a set of targeted complex algorithms

The currently commonly used stand-alone structure is unsatisfactory in terms of computing power, real-time performance, reliability and rationality of the process.
