Method for implementing vehicle-mounted dynamic weighing

Abstract

The invention provides a method for implementing vehicle-mounted dynamic weighing. A vehicle-mounted dynamic weighing system, which comprises a CPU (Central Processing Unit), a multi-channel AD (Analog / Digital) module, a speed sensor module, an acceleration sensor module, a line concentrator and a plurality of weighing sensors, is adopted in the method. The method comprises steps of: forming a proper data model according to the difference and relations among signals acquired in various states of a vehicle in running by comprehensively considering the vehicle speed, acceleration, vibration of a vehicle body, gradient of a pavement and the like, and finally carrying out data processing by a filter algorithm and an interpolation algorithm, so that the vehicle-mounted weighing device can reach high weighing precision. The method is simple in principle and fast in operation speed, and is suitable for vehicle-mounted weighing systems of various forms.

Description

technical field [0001] The content of the present invention belongs to the technical field of vehicle weighing, and relates to a signal processing method capable of realizing vehicle dynamic weighing. Background technique [0002] With the continuous development of the market economy and the rapid growth of the logistics industry, a series of problems such as vehicle overloading, road congestion, and infrastructure safety have also followed. New requirements, resulting in the exploration of new vehicle weighing technologies that can meet the balance between weighing accuracy and traffic efficiency, have been put on the agenda. [0003] At present, the well-known measurement methods in the field of vehicle weighing mostly adopt the method of separating weighing and driving state, that is, the method of measuring when the vehicle is stationary, and is mainly applied to a certain extent on specific engineering vehicles. However, the load weighing of the vehicle during dynamic ...

AI Technical Summary

Problems solved by technology

However, the load weighing of the vehicle during dynamic operation is affected by many factors, such as: the type of vehicle, the condition and roughness of the road surface, the speed and acceleration of the vehicle, the dynamic balance of the vehicle, the state of the tires and the driver's operating ability, etc., so it is more difficult to achieve vehicle weighing in the driving state
