Electronic police checkpoint system capable of enhancing human eye light adaptive capacity at night

Abstract

The invention relates to an electronic police checkpoint system capable of enhancing human eye light adaptive capacity at night. The system can effectively solve the problem that an existing checkpoint system flashing light severely affects the vision of drivers or pedestrians. According to the technical scheme, the system comprises a video detecting and photo capturing device, a light adaptation additional light supplementing device with the lighting brightness increasing gradually in the vehicle coming direction is arranged on the front side of the video detecting and photo capturing device, and a dark adaptation additional light supplementing device with the lighting brightness decreasing gradually in the vehicle going direction is arranged on the rear side of the video detecting and photo capturing device. The electronic police checkpoint system is novel and unique in structure, simple, reasonable, safe, reliable, capable of effectively solving the problem that the checkpoint system flashing light affects the vision of the drivers or the pedestrians, low in cost, convenient to install and good in use effect and has good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, in particular to an electronic police bayonet system that enhances the ability of human eyes to adapt to light at night. Background technique [0002] The phenomenon that the human eye's sensitivity to light decreases is called light adaptation, including light adaptation and dark adaptation. When people first come from a dark place to a bright place, they feel a dazzling light at first, and cannot see objects clearly. They can only recover their vision after a while. This is called photopic adaptation. On the contrary, when a person enters a dark room from a bright place, he can't see anything clearly at first, and after a certain period of time, his visual sensitivity gradually increases until his vision is restored. This is called dark adaptation. The light adaptation time of human eyes is within one minute, while the dark adaptation time can be as long as tens of minutes. [0003]...
