Control method based on multi-combination intelligent traffic checkpoint light fill-in light

Abstract

The invention discloses a control method based on a multi-combination intelligent traffic checkpoint fill-in light. The fill-in light comprises a daytime fill-in light group, a night fill-in light group and a stroboscopic fill-in light group which are controlled by a microprocessor. The control method comprises the following steps: sensing the ambient light intensity of a snapshot section; and when the ambient light intensity is higher than a set threshold value, enabling the fill-in light to work according to a daytime mode; and when the ambient light intensity is lower than a set threshold value, enabling the fill-in light to work according to a night mode. The microprocessor is used for judging the light intensity of a snapshot section as daytime or night, different fill-in light sets are combined according to different light supplementing requirements of the daytime and the night, and the contradiction of excessive explosion caused by insufficient light supplementing or excessive light supplementing due to large difference of ambient light in the daytime is eliminated; and meanwhile, by acquiring a vehicle arrival signal at night and driving the working mode of the fill-in light set, the problem of resource waste caused by strong light supplementing at night and constant lighting of the stroboscopic light fill-in light set is solved.

Description

technical field [0001] The invention belongs to the technical field of traffic supplementary lights, and in particular relates to a control method based on multi-combination intelligent traffic bayonet supplementary lights. Background technique [0002] In the bayonet application in the field of intelligent transportation, the combination of LED strobe light and gas flash light is often used to supplement light. In order to obtain clear video images, LED strobe light is used for supplementary light; in order to capture facial information of drivers and passengers, Gas strobe flash fill light. [0003] The above methods of supplementary light have the following problems: gas flash flash supplementary light can be used to capture supplementary light at the same brightness in daytime and night, and it is difficult to take into account the capture effects of night and day and different ambient light with the same light intensity. , it is very easy to cause insufficient fill lig...
