Problems solved by technology

[0002] The vehicle dynamic weighing system known to the public generally consists of a dynamic scale or a dynamic weighing sensor as its weighing component, but the data of this weighing system is unitary. When the road condition is bad, the vehicle passes through the detection device. It is possible that jumping and squatting will make the weighing data inaccurate; at the same time, due to the characteristics of the sensor, the load cell is often only installed on one side of the lane, and some drivers take the "S"-shaped route to avoid the load cell , making the dynamic weighing system useless; in addition, the speed of the vehicle also affects the weighing. When the vehicle passes the checkpoint due to the different speed, the system cannot judge the driving state of the vehicle, and cannot judge whether there is any abnormal driving. These problems are serious. Affected the normal vehicle weighing inspection work

Abstract

The invention provides a weight-in-motion system for vehicles and a weighing method thereof. The weight-in-motion system comprises a controller and multiple wheel load weighing sensors, wherein the controller is respectively connected with the multiple wheel load weighing sensors, an abnormal driving data compensation weighting method is characterized in that the value of the vehicle driving accelerated speed is calculated and is compared with a threshold value of the vehicle driving accelerated speed, whether the vehicle drives normally is judged and abnormal data are compensated, and then the dynamic wheel load of a vehicle to be detected is calculated; and an abnormal wheel load information filtering and weighing method is characterized in that each piece of wheel load information is compared with a preset wheel load information threshold value so as to judge whether the wheel load information is abnormal and perform the compensation on abnormal data, and then the dynamic wheel load of the vehicle to be detected is calculated. The weight-in-motion system for the vehicles has the advantages of scientific design and high weighing precision; and the weighing method has the advantages of scientific design, high weighing precision, automatic error correction, cheating prevention, and vehicle driving state detection intellectualization.
