As shown in fig. 4, since the position of the vehicle relative to the photometer is changed, the luminous flux of the light captured by the photometer forms a gradually increasing and gradually decreasing change curve with time; if the light source is a fixed light source, the luminous flux of the light captured by the photometer is changed violently, but is stable for a long time, and a change curve which becomes stable after being gradually strengthened is formed, and is different from the light intensity change generated by a moving light source of the vehicle.

when the vehicle arrives or passes through the sensor 6, since the national standard states that when the dipped headlight is well adjusted, the bright-dark cut-off of the light on the road surface is 75 meters away from the vehicle, whether the light irradiation which does not accord with the characteristics of the dipped headlight is present or not can be judged according to the characteristics to determine whether the high beam is turned on or not, and meanwhile, in practice, the light irradiation ranges of the dipped headlight and the high beam of the vehicle are overlapped, so that the first photometer 5 which is 75 meters away from the sensor starts to detect the light of the vehicle, and whether the high beam is used by the vehicle or not is judged in advance.

If the first photometer 5 detects light, data is transmitted to the front computer 3 to draw a light flux change map, when a change curve of light flux rises first and then falls with time, it is judged in advance that the vehicle uses a high beam, and if the first photometer 5 does not detect light, it is judged that the vehicle uses a low beam.

After first photometer 5 judges in advance that the vehicle has used the high beam, when the vehicle moves to the detection position, second photometer 7 detects vehicle light, if second photometer 7 detects light, draws the luminous flux variation graph with data transmission to front end computer 3, descends after rising earlier with time as the change curve of luminous flux, then finally judges that the vehicle has used the high beam, and the vehicle license plate is shot to camera 8, if second photometer 7 does not detect light, then finally judges that the vehicle has used the passing lamp.

The detection position L is the vertical distance between the plane where the vehicle is located and the plane where the second detection assembly is located, whether the traffic control department penalizes or not is judged according to the video of 5 seconds of vehicle running, therefore, the detection position L is set to be determined according to the distance which can be passed by the vehicle running for 6 seconds at the actual road speed limit S, the actual road speed limit is S, and the specific formula for obtaining the detection position L is that L is greater than or equal to S/3600 x 6.
