Vehicle shape parameter measurement system and method based on full grating structure

Abstract

The invention provides a vehicle configuration parameter measuring system and method based on a full-grating structure. The system comprises the full-grating structure, an information collection and storage module and a calculating and processing module which are connected in sequence, wherein the full-grating structure is connected with the information collection and storage module and transmits optical signal information, and the information collection and storage module is connected with the calculating and processing module and transmits optical signal information with time stamps; the full-grating structure comprises a detection triggering grating, a grating portal frame composed of a transverse grating group and a vertical grating group, and a longitudinal grating group. According to the invention, the low-cost full-grating structure is used, and under the condition that the normal driving of the vehicle is not influenced, configuration parameters of a vehicle to be detected, such as the length, the width, the height, the number of axles and the axle interval, are precisely and rapidly measured, so that illegally modified vehicles can be discovered in time, and fatal traffic accidents caused by the illegally modified vehicles are reduced.

Description

technical field [0001] The invention relates to a technology in the field of test and measurement, in particular to a system and method for measuring vehicle shape parameters based on a full grating structure. Background technique [0002] With the rapid development of my country's economy, the utilization rate of various large trucks in the logistics and transportation industry is increasing year by year. Due to increasingly fierce competition, many managers of vehicle transportation companies increase their business turnover by reducing transportation costs. They usually make some illegal modifications to large trucks in order to increase the carrying capacity of vehicles and reduce transportation costs. However, major traffic accidents caused by illegal modification of trucks occur frequently, resulting in a large number of property and personnel losses. In order to avoid such accidents, we need to detect various parameters of the vehicle shape, and judge whether the veh...

Problems solved by technology

However, this method needs to use multiple cameras for detection, the system is relatively complex, and the site required for construction is relatively large. Not only does the entire body of the vehicle need to be in the detection area, but also there is a certain limit on the length of the vehicle to be inspected. In addition, this method only It can detect the length, width and height of the vehicle, but cannot detect the wheel-axle spacing, so there are certain limitations
