Anti-glare automatic light change and supplement device of intelligent toll gate

Abstract

The invention belongs to the technical field of road traffic intelligent toll gates and particularly relates to an anti-glare automatic light change and supplement device of an intelligent toll gate. The anti-glare automatic light change and supplement device comprises a vehicle distance detection unit, a trigger unit, a drive unit and an electric light source light-emitting unit. The vehicle distance detection unit is used for detecting the distance between a vehicle and the toll gate, when the distance reaches a set value, a control signal is output to the drive unit, the drive unit adjusts output power, and accordingly the luminance of the electric light source light-emitting unit gradually increases from low luminance; when the vehicle arrives at the trigger position of the trigger unit, the trigger unit outputs a signal to the drive unit, the drive unit receives the signal and then drives the electric light source light-emitting unit to flash rapidly, and therefore snapshot light supplement is achieved and the rapid flashing electric light source light-emitting unit recovers low-luminance illumination. The functions of illumination, gradual brightening conducted when the vehicle gets close and rapid flashing snapshot conducted when the vehicle runs to the trigger position of the electric light source light-emitting unit are achieved by monitoring the vehicle distance, visual interference caused by rapid flashing in a driver and passengers is prevented, driving safety is improved, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of road traffic smart checkpoints, in particular to an anti-glare automatic dimming and supplementary light device for smart checkpoints. Background technique [0002] When the smart bayonet works at night, the lighting system needs to provide regular lighting functions for pedestrians and vehicles, and provide supplementary light functions for video cameras and strobe capture supplementary light functions for cameras. For conventional lighting, from the point of view of energy saving, the light intensity should be as small as possible under the premise of providing sufficient lighting brightness; for camera recording and supplementary light, the required light intensity is higher than the light that only maintains conventional lighting. It is much stronger; and the light intensity of the flash capture is even greater. [0003] Existing bayonets usually use constant power LED lights or a combination of LED ...

AI Technical Summary

Problems solved by technology

There are many disadvantages in this combination method: First, the structure and control of different types of fill lights are more complicated, which increases the cost of installation and maintenance; The required light intensity is different. It is difficult for a constant power LED light to meet the needs of these two situations at the same time. If it is too bright, it will cause energy waste, and if it is too dark, it will cause insufficient light for the camera; The difference in light intensity between the two is too large, which is likely to cause visual interference to the passengers
