Laser scanning vehicle separating device integrated with automobile axle recognition function and implementation method

Abstract

The invention discloses a laser scanning vehicle separating device integrated with an automobile axle recognition function and an implementation method. The vehicle separating device comprises a mounting bracket, a rotary reflecting module, a distance measuring module, an image processing and analysis module, a main control module and a power supply module, wherein the rotary reflecting module, the distance measuring module, the image processing and analysis module, the main control module and the power supply module are mounted in a shell; a laser emitter is induced to emit a pulse laser beamthrough an electric pulse signal, the pulse laser beam is converted into a laser beam array through the rotary reflecting mechanism so as to achieve three-dimensional image restoration on an object passing through the beam array, and then analytical processing is performed on the image so as to realize vehicle separation and obtain axle information. Compared with the traditional vehicle separatorand axle recognition device, the laser scanning vehicle separating device can realize the functions of vehicle separation and axle recognition simultaneously, thereby reducing the number of devices,being easy for field installation and construction, not only reducing the cost, but also increasing the flexibility. In addition, the laser scanning vehicle separating device adopts real-time image scanning, and also greatly improves the detection and measurement accuracy. The non-contact measurement prolongs the service life and is easy in construction, and the laser scanning vehicle separating device is assembled and disassembled conveniently and not restricted by the field environment.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a laser scanning vehicle divider with an integrated vehicle axle identification function and a realization method. Background technique [0002] In recent years, my country's economy has developed rapidly, and the transportation industry, as a link of economic exchanges, has also shown an increasingly important influence. At the same time, various related problems have repeatedly emerged, especially the problem of overloading, which not only causes damage to roads and bridges but also affects traffic safety. In order to solve the problem of overloading, high-speed weighing has become particularly important, and the separation of vehicles and the measurement of axle types are important supports for the weighing system. [0003] At present, the vehicle separator used in the high-speed weighing system is mainly a grating separator, which adopts the principle of the opposit...

Problems solved by technology

These products are all contact detection, which leads to easy damage to the equipment and low service life. In addition, the road surface or scale body needs to be broken during installation. The construction and installation process is complicated, and the later maintenance cost is high, time-consuming and labor-intensive.

[0005] At present, most of the related equipment for car division and axle measurement are single-function equipment, and two kinds of equipment are required to be used together in the process of use. Increasing the number of equipment increases the failure rate of the equipment and increases the cost input.
