Abstract

The invention relates to the technical field of illumination control, in particular to a tunnel lamp intelligent control method and system and a tunnel lamp, and the method comprises the following steps: collecting the operation parameters and fault times of each type of lamps in a tunnel in real time, comparing the operation parameters of each type of lamps with a corresponding preset risk threshold value, and generating a preliminary analysis result of the operation risk of the lamps. According to the invention, through collecting the tunnel lamp operation parameters and the number of faults in real time and combining the comparative analysis of the preset risk threshold value, the risk quantification and grading of the lamp operation state can be carried out, and the dynamic comprehensive probability calculation mode enables the potential problems of the lamp to be accurately early warned. And hidden danger omission possibly caused by static judgment of a single parameter is avoided. On the basis, load balancing is carried out based on the running state of the lamp and the brightness load, and the accuracy and the high efficiency of dynamic adjustment of the brightness of the lamp are achieved through brightness trend change prediction.
