Vehicle dynamic weighing axle identification system and realization method thereof

Abstract

The invention relates to a vehicle dynamic weighing axle identification system. The system comprises a basic weighing platform, an axle identification loader, axle identification sensors and an axle identification controller, wherein the signal output ends of the axle identification sensors are connected with the signal input end of the axle identification controller, each path of axle identification is composed of four axle identification sensors, two sensors at each side of the axle identification loader vertical to a driving direction are connected in parallel to form one path of signals, and the axle identification controller is used for receiving data information acquired by the axle identification sensors, performing classification processing on these data information and calculating the quantity of axles, vehicle speeds and driving directions of vehicles passing by. According to the invention, the quantity of the axles, the driving directions and the driving speeds can be effectively obtained, the phenomena of too many axles and too few axles in a continuous passing process are solved, and the vehicle pass efficiency of a highway is effectively improved.

Description

technical field [0001] The invention relates to an identification system and a realization method of an expressway vehicle dynamic weighing axle identification system. Especially the axle identification system that can accurately and reliably identify the number of axles, driving direction, and driving speed of passing vehicles. Background technique [0002] At present, the well-known expressway dynamic weight toll system is a system that collects fees according to the total weight of vehicles by dynamically weighing passing vehicles. The system installs dynamic truck scales and wheel axle identifiers in the toll lanes, and through data collection, calculation and analysis, the number of axles, speed, and direction of each axle of each vehicle are known, so as to obtain the basis for charging. [0003] In the process of obtaining vehicle weight information, the number of axles is mainly obtained through the axle identification sensor. Most of the existing axle identificatio...

AI Technical Summary

Problems solved by technology

[0003] In the process of obtaining vehicle weight information, the number of axles is mainly obtained through the axle identification sensor. Most of the existing axle identification devices are the axle identifier at the upper scale end and the axle identifier at the lower scale end, and the axle identifier is particularly narrow. The behavior of the vehicle’s scale jumping is very easy to skip the axle identifier, and at the same time, it is impossible to accurately judge the reversing behavior. In the case of continuous passing, it is easy to have multiple axles, few axles, misalignment of vehicle information and axle information, and affect traffic efficiency. , since the axle recognition sensor has only one signal, the sampling time is too short when the vehicle passes, and the speed and direction of the passing vehicle cannot be accurately calculated
