Toll station vehicle separation detection light curtain sensor

Abstract

The invention relates to the technical field of light curtain sensors, and discloses a toll station vehicle separation detection light curtain sensor which comprises a connecting plate, the left end and the right end of the connecting plate are fixedly connected with two sets of supporting bases respectively, the upper surfaces of the supporting bases are fixedly connected with the bottom end of ashell, and the top of the shell is fixedly connected with a spring. According to the toll station vehicle separation detection light curtain sensor, a hand wheel is rotated to drive a rotating shaftto rotate, the rotating shaft drives a second bevel gear to rotate, the second bevel gear is matched with a first bevel gear, a threaded rod is enabled to rotate, then a movable plate ascends and descends under limiting of the threaded rod, and the height of the light curtain sensor is adjusted; the distance between the two sets of clamping plates can be adjusted conveniently, the light curtain sensors of different sizes are fixedly clamped, the two sets of supporting bases are located on the same horizontal plane through the arranged connecting plates, and signal transmission between the twosets of light curtain sensors is facilitated.

Description

technical field [0001] The invention relates to the technical field of light curtain sensors, in particular to a toll station vehicle separation detection light curtain sensor. Background technique [0002] The vehicle separation light curtain at toll stations at expressway intersections is used for the detection and discovery of vehicles at toll stations such as expressways, airports, and parking lots. It is mainly used in highway toll stations, non-stop toll collection systems (ETC light curtains), automatic vehicle classification systems (AVC ) Parking toll system, road weight toll system (WIM), fixed overrun detection station, customs vehicle management system and other occasions, it is the key equipment in the traffic control system, and it is applied to the expressway toll station to realize ETC unmanned toll collection Advanced infrared vehicle detector, equipped with a special stainless steel protective cover, built-in electric heating glass, temperature controller, ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a toll station vehicle separation detection light curtain sensor, which solves the lack of protection measures for the existing light curtain sensor, the light curtain sensor is easily damaged by external force collision, and the fixation of the light curtain sensor Instability, which reduces the problem of its use efficiency
