A yard vehicle comprehensive detector, detection system and detection method

Abstract

The invention belongs to the technical field of motor vehicle detection, and discloses a field vehicle comprehensive detector, a field vehicle comprehensive detection system and a field vehicle comprehensive detection method. The detection system comprises a road slope detection module, a brake performance test module, a maximum speed linear driving deviation condition detection module, a maximum slope downhill braking test module, a maximum corner sideslip detection module and an upper computer module. The field vehicle comprehensive detector provided by the invention is used for detecting the road slope of a field vehicle in running, the running distance in the braking process and the sideslip of the field vehicle in real time; the data are transmitted by a distributed sensing network, collected by a plurality of channels by using a terminal, and a reliable real-time result is obtained after a signal processing algorithm; and the detector analyzes whether the requirements of the state are met or not, and avoids the occurrence of brake failure, thereby strengthening the safety management work of the motor vehicles in the field, reducing the traffic accidents of the vehicles in the field in China and protecting the life and property safety of people.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle detection, and in particular relates to a yard vehicle comprehensive detector, a detection system and a detection method. Background technique [0002] Currently, the closest prior art: [0003] Special-purpose motor vehicles in the field (factory) (hereinafter referred to as field vehicles) refer to special-purpose motor vehicles that are only used in specific areas such as factory areas, tourist attractions, and playgrounds other than road traffic and agricultural vehicles, including motorized industrial vehicles (forklifts) And non-highway tourist vehicles. [0004] Motorized industrial vehicles and non-highway tourist vehicles are indispensable: forklifts are widely used in ports, stations, airports, freight yards, logistics centers, etc., and can enter cabins, carriages and containers for loading and unloading, stacking and handling of palletized goods , is an indispensable equipment ...

AI Technical Summary

Problems solved by technology

When the truck is used for a long time, the wear of the friction plate will increase, the braking distance of the vehicle will also become longer, and the risk encountered by the motor vehicle in the operation will be greater

[0012] 2) The friction between the road surface and the tires, when the tires are severely worn, or the road surface is relatively smooth, the friction force between the tires and the road surface will become smaller, the braking distance of the vehicle will increase, and the motor vehicle will not be easily controlled by the brakes

[0019] (1) At present, there is a lack of portable, Advanced testing equipment

[0020] (2) Multiple inspection items of domestic motor vehicles in the field are still in the stage of empirical inspection, and the whole process has not yet reached the level of quantification and standardization

There are no specific inspection standards for the new requirements and inspection items, and there are still vacancies in inspection instruments and equipment, and high-end instruments need to be developed and utilized

[0021] (3) Existing equipment cannot record the historical track of the field vehicle

Although the device is equipped with a dot-matrix LCD screen as a display device, it can display test data in real time, but due to the size of the display interface, the entire display result is not clear. From the analysis of the total score of the full performance evaluation, a single data cannot Overall get the full report

[0026] The braking performance tester and parking brake performance tester of Lingxin Electronic Technology Co., Ltd. can test the braking speed, braking distance and parking braking force respectively, although both can print the test data as paper documents and save them. , but the historical data cannot be saved in the form of documents, and it cannot play the role of historical tracking

At the same time, the device is limited by storage space and computing power, resulting in a small amount of collected data, resulting in low detection accuracy
