Problems solved by technology

[0002] At present, the ETC gantry adopts a redundancy scheme in which two capture cameras, one active and one backup, work simultaneously for each lane. Each camera is connected to a supplementary light. Constantly on, the fill light is too bright, which may cause driving safety hazards and consume energy

Abstract

The invention discloses an ETC door frame light supplement lamp automatic control method and device. The method comprises the steps: acquiring the light intensity of the current environment of an ETC door frame; turning on or turning off a main light supplement lamp or a standby light supplement lamp in ETC portal frame light supplement lamps according to the light intensity of the environment; and when the light supplement lamp is turned on, adjusting the duty ratio of the ETC door frame light supplement lamp in real time according to the change of the light intensity of the environment, so that the definition of the image of the ETC door frame camera is ensured, and the automatic control of the light supplement lamp is completed; and the problems of driving potential safety hazards caused by simultaneous turning-on of the main and standby light-supplementing lamps and energy consumption caused by simultaneous turning-on of the main and standby light-supplementing lamps and incapability of adjusting brightness are solved.

Description

technical field [0001] The application relates to the field of intelligent control, in particular to an automatic control method for an ETC mast supplementary light, and at the same time relates to an automatic control device for an ETC mast supplementary light. Background technique [0002] At present, the ETC gantry adopts a redundancy scheme in which two capture cameras, one active and one backup, work simultaneously for each lane. Each camera is connected to a supplementary light. Constantly on, the supplementary light is too bright to cause driving safety hazards and consume energy. Contents of the invention [0003] In order to solve the above problems, this application provides an automatic control method for ETC gantry supplementary light, including: [0004] Obtain the light intensity of the current environment of the ETC gantry; [0005] According to the light intensity of the environment, turn on or off the main fill light or backup fill light in the ETC gantr...
