System and method for automatically measuring dimension and weight of road vehicle

Abstract

The invention relates to a system and a method for automatically measuring dimension and weight of a road vehicle, in particular to an integrated system and an integrated method for rapidly and dynamically measuring the length, width, height and weight of a vehicle, and aims at effectively solving the problems in overloading detection work at present. According to the system, the dimension information of the vehicle is measured in a front and back portal frames manner; the width and height information of the vehicle in a single lane is measured by combination of two two-dimensional laser radars on the front portal frame, so that the measurement problem caused by vehicle deformation can be effectively avoided; and the length information of the vehicle in the single lane is indirectly measured by virtue of a single laser radar on the rear portal frame; and starting and stopping information of the single vehicle is provided for a shaft-type weighing scale by virtue of a laser radar separation vehicle on the front portal frame. The system has the advantages of high measurement speed and high accuracy, and normal running of the vehicle is not affected.

Description

technical field [0001] The invention relates to a system and method for automatically measuring the size and weight of road vehicles, in particular to an integrated system and method for dynamically and quickly measuring vehicle length, width, height and weight. Background technique [0002] With the rapid development of the national economy, the scale of highway construction is increasing. The total mileage of my country's highways has exceeded 4 million kilometers, ranking first in the world. Road freight passenger transport is of great importance to the development of the national economy, but in order to pursue greater profits, vehicle overrun transportation has become a very common problem. Great harm, seriously endangering the lives and property of the people and the safety of national property. In order to prevent over-limit vehicles on the road, toll stations at all levels and important road entrances have established over-limit detection projects to detect and deal...

Problems solved by technology

[0003] However, controlling overruns is a very complicated and arduous task. Our country invests a lot of money in overrunning every year. The phenomenon of overruns has been alleviated, but the governance effect is still not ideal.

One of the most important reasons for the unsatisfactory treatment effect is that the vehicle's overrun detection methods and equipment are not perfect

At present, it is mainly used for vehicle detection equipment, and the division of labor is relatively clear. There is no intersection between the measurement methods of each equipment, which causes a waste of equipment and space; and for the geometric dimensions of the vehicle's length, width, and height, it mainly depends on the height limit bar and Human eye experience observation, tape measure direct contact and other methods of measurement, which result in low measurement accuracy, poor measurement efficiency, increase the workload and labor time of operators, and reduce the speed of transportation
