Abstract

The invention relates to a self-adaptive stepless dimming control system and method for a tunnel lighting system. The control system comprises a tunnel lighting lamp, a light intensity detector, a vehicle detector, a visibility detector and a stepless dimming controller. The light intensity detector, the vehicle detector and the visibility detector are connected with the stepless dimming controller, and the stepless dimming controller controls and is connected with the tunnel lighting lamp. The control system and the control method have the advantages that on the basis of an existing stepless dimming control system for tunnel lighting, tunnel lighting lamps are adjusted by additionally collecting brightness parameters and visibility parameters in a tunnel hole, potential safety hazards caused by attenuation of the luminous flux maintenance rate of the lamps and low visibility in the tunnel can be avoided, and a safe and comfortable driving environment is provided for a driver.

Description

technical field [0001] The invention relates to the technical field of dimming control, in particular to an adaptive stepless dimming control system and a control method for a tunnel lighting system. Background technique [0002] The tunnel lighting system starts from the driver's visual characteristics to ensure that vehicles can completely enter, pass and leave the tunnel area; with the development of tunnel construction today, more and more tunnel lighting lamps are controlled by stepless dimming. [0003] The existing stepless dimming control system for tunnel lighting is mostly adjusted by collecting brightness parameters outside the tunnel and tunnel traffic parameters, and also solves the "blind-sight effect" caused by frequent brightness jumps through a reasonable control process. The disadvantages of this control method are: 1. During the rated service life of tunnel lighting lamps, the luminous flux maintenance rate of the lamps will attenuate, which will cause the...
