The embodiment of the invention provides an automatic detection device for tunnel illumination, as shown in fig. 1, comprising:
the processing module 1 is arranged at a first preset position in the tunnel; for example: the center position of every 200m of separated areas from one end of the tunnel is used as a first preset position;
the first vehicle detection module 2 and the second vehicle detection module 3 are respectively arranged at a second preset position and a third preset position in the tunnel; the second preset position and the third preset position are respectively positioned on two sides of the first preset position; for example: the second preset position and the third preset position are any positions which are at a distance of 50-100 meters from the first preset position;

the processing module 1 is respectively connected with the first vehicle detection module 2, the second vehicle detection module 3, the first light control module 4 and the second light control module 5;
when the processing module 1 detects a train through the first vehicle detection module 2 and does not detect the train through the second vehicle detection module 3, the lighting lamp on one side far away from the first vehicle detection module 2 is controlled to be turned on through the second light control module 5;
when the processing module 1 detects a train through the second vehicle detection module 3 and does not detect the train through the first vehicle detection module 2, the lighting lamp on one side far away from the second vehicle detection module 3 is controlled to be turned on through the first light control module 4.
The working principle and the beneficial effects of the technical scheme are as follows:
in a practical application example, the arrangement position of the processing module 1 is taken as a middle boundary, and the vehicle detection modules and the illuminating lamps on the two sides are staggered and associated to be turned on, so that the illumination can be detected and turned on no matter which direction of the tunnel drives into the train; it is not considered here that vehicles enter the tunnel from both directions at the same time; instead, the train enters the tunnel from one side of the tunnel as it goes, and enters the tunnel from the other side of the tunnel as it goes back.
When a train drives from one side of the first vehicle detection module 2, the first vehicle detection module 2 is triggered firstly; when the first vehicle detection module 2 is triggered, the second vehicle detection module 3 is not triggered, and an illuminating lamp on one side of the second vehicle detection module 3 is controlled to be started for illumination;
when the train drives from one side of the second vehicle detection module 3, the second vehicle detection module 3 is triggered firstly; when the second vehicle detection module 3 is triggered, the first vehicle detection module 2 is not triggered, and the lighting lamp on one side of the first vehicle detection module 2 is controlled to be started;

In one embodiment, when the first vehicle detection module 2 of the automatic detection device 12 is triggered first, the second vehicle detection module 3 is triggered later; after the second vehicle detection module 3 finishes triggering, turning off an illuminating lamp on one side of the second vehicle detection module 3; at this time, the illumination lamps controlled by the automatic detection device 12 are between the first vehicle detection module 2 and the processing module 1 and between the first vehicle detection module 2 and the processing module 1. The delayed closing can also be adopted, namely, after the second vehicle detection module 3 finishes triggering, timing is carried out, and when a preset timing threshold value (for example: 30 seconds) is reached, a lighting lamp on one side of the second vehicle detection module 3 is closed; thus, the second detection module is not required to be arranged outside the outermost controlled illuminating lamp.
