Expressway traffic night vision emergency speed measurement equipment

Abstract

The invention discloses expressway traffic night vision emergency speed measurement equipment which comprises a supporting column, a cross beam frame is arranged on one side of the supporting column, and a reinforcing piece is arranged between a connecting sleeve and the cross beam frame. The mounting seat is arranged above the cross beam frame, an equipment shell is arranged above the mounting seat, and a high-definition camera is arranged on one side of the equipment shell; the heat dissipation groove is formed in the equipment shell, a rain baffle is arranged on one side of the equipment shell, and the rain baffle is connected with the equipment shell through screws; and the U-shaped mounting block is arranged in the equipment shell, an adjusting groove is formed in the equipment shell, and an adjusting block is arranged in the adjusting groove. The light intensity can be increased at night, so that shot images are clearer, the speed measurement precision is indirectly improved, light energy can be converted into electric energy to be stored and used, power can be supplied to speed measurement equipment in emergency, and the night vision emergency use effect is better.

Description

technical field [0001] The invention relates to the technical field of expressway traffic, in particular to a night vision emergency speed measuring device for expressway traffic. Background technique [0002] Expressways are high-grade highways, referred to as expressways for short. Expressways are road types classified according to technical grades, and their grades are higher than first-class roads, second-class roads, third-class roads, fourth-class roads and substandard roads. The national highway or provincial highway under the classification of highway and road network status is a cross relationship, that is, the highway is a part of the national highway or provincial highway in the road network, and the highway refers to the annual average day and night passenger car traffic volume of 25,000 vehicles. The above roads are specially designed for cars to drive at high speed in separate lanes, and all access and exit are controlled. The speed measuring equipment refers ...

AI Technical Summary

Problems solved by technology

[0003] At present, the speed measuring equipment on the expressway traffic is all suspended installations, and there is no corresponding backup power supply mechanism on the speed measuring equipment. Good, the visibility is reduced, the speed measurement equipment is not clear enough to shoot the vehicle, which increases the speed measurement accuracy error, the night vision emergency use effect is not good, and cannot meet the needs of use. Therefore, a highway traffic night vision emergency speed measurement is needed equipment to solve the problem
