Vehicle dimension automatic measurement instrument system

Abstract

The invention relates to a vehicle dimension automatic measurement instrument system, which comprises a portal frame, two long rails, two positioning optical gratings, a power supply cabinet, three groups of high-speed detection optical gratings and a control module, wherein the portal frame is in a rectangular shape formed by four square stripes; the two opposite square strips are mutually parallel; the two long rails are mutually parallel, and are respectively arranged at the two sides of the portal frame; a certain height is formed between the ground and the long rails; the two positioning optical gratings are respectively arranged on the corresponding long rails, correspond to each other, and are used for positioning the position of a vehicle; the power supply cabinet is positioned at one side of the long rails, and is mainly used for providing a power supply for a vehicle dimension automatic measuring instrument system; the three groups of high-speed detection optical gratings are respectively arranged on the surfaces of the portal frame and the long rails, and are used for measuring the practical outer contour data of the vehicle; the control module is connected with the portal frame and the long rails. The optical point intervals of the high-speed detection optical gratings are fine, so that the precision is high; meanwhile, the influence by external environment cannot be easily caused.

Description

【Technical field】 [0001] The invention relates to an automatic measuring instrument system, in particular to an automatic measuring instrument system for vehicle dimensions. 【Background technique】 [0002] At present, in order to achieve the purpose of overloaded transportation, some car owners carry out various modifications to the vehicle, such as thickening the steel plate of the vehicle and increasing the size of the compartment. Vehicle overloading has become a prominent problem that seriously affects the safety of the country and people's life and property, and endangers the stability of social and economic order. In order to check from the source, all public security vehicle management offices and motor vehicle inspection stations must conduct compulsory inspections on the outline dimensions of newly registered vehicles and in-use motor vehicles that exceed the limit; , It is also necessary to detect various vehicle outline dimensions that exceed the limit. At prese...
