technical field

The present application relates to the field of road lighting, in particular to a method and terminal for analyzing the flicker effect of street lamps.

The flickering effect of street lights on a road section is periodic flickering in the space domain, which is caused by the flickering period of the street lights being higher than the time required for the human eye to distinguish afterimages when the driver of a driving vehicle passes the road section with street lights at intervals. The International Council of Illumination (CIE) pointed out in the 88-2004 "Guide For the Lighting oF Road Tunnels and Underpasses" that the flicker frequency of the flicker effect depends on the driving speed and the distance from the light.

However, in actual operation, even if the street lighting system is set according to the regulations of CIE or JTJ, there is still an obvious phenomenon of spatial domain flickering effect in the actual experience of motor vehicle drivers, that is to say, when the vehicle speed is constant, only the road section is considered The influence of the street lamp spacing on the flicker effect is not enough, and there will be a great safety hazard. Therefore, there is an urgent need for a more reasonable analysis method and terminal for the flicker effect of street lamps to ensure the safety of vehicles.

Wherein, the flicker effect threshold F _a is a preset value. In one embodiment, the flicker effect threshold F _a is a flicker effect index critical value when the driver can obviously feel the flicker effect.

For example, the horizontal length of the light-emitting surface of a street lamp in a road section S=0.40m, the frontal brightness of the street lamp L=700cd/m ² , the distance between street lamps D=6.0m, and the average brightness along the road side B=7.0cd/m ² , which is substituted into step 204 According to the calculation formula in , the street lamp flickering effect index F _I of this road section can be obtained = 80.7%; let F _a be 10%, because 80.7% is greater than 10%, that is, F _I >F _a , so it is judged that there are street lights flickering in this road section effect problem. The embodiment of the present invention also conducts actual measurement and verification of this situation, and it is found that within the normal vehicle speed range, no matter what the vehicle speed is, there is always a flickering effect under this condition.

For another example, the horizontal length of the light-emitting surface of a street lamp on a certain road section is S=1.2m, the front-view brightness of the street lamp is L=100cd/m ² , the distance between street lamps is D=0.1m, and the average brightness value along the side of the road is B=70cd/m ² . The calculation formula in 204 can get the street lamp flicker effect index F _I =2.2% of this road section; set the flicker effect threshold F _a as 10%, because 2.2% is less than 10%, that is, F _I <F _a , so judge this road section The street light flicker effect problem can be ignored. The embodiment of the present invention also conducts actual measurement and verification of this situation, and it is found that within the normal vehicle speed range, no matter what the vehicle speed is, the flickering effect under this condition can be ignored.

As explained above, the street lamp flicker effect analysis method described in this case detects the flicker effect status through the flicker effect index, and the street lamp flicker effect index is related to the brightness or illuminance of the road environment where the street lamp is located, the brightness value or illuminance value of the street lamp, and the luminous value of the street lamp. It is accurate and effective because it is related to the horizontal length of the surface and the distance between adjacent street lights.

In one embodiment, the street lamp flicker effect analysis method further includes step 308: adjusting the brightness value or illuminance value B of the road environment of the road section according to the judgment result in S305.

In one embodiment, if the street lamp flicker effect index F _I of a road section is greater than or equal to a flicker effect threshold F _a , then increase the brightness value or illuminance value B of the road environment of the road section; and then perform the step 304 Proceed to one or more steps in step 308 until the street lamp flicker effect index F _I of the road section is less than the flicker effect threshold F _a .

Wherein, at least one auxiliary light source is provided on the side of the road between each adjacent street lamp, and the brightness value or illuminance value B of the road environment of the road section is increased to turn on at least one auxiliary light source; preferably, the The brightness of the auxiliary light source is adjustable, so that if the at least one auxiliary light source has been turned on, the street lamp flicker effect index F _I is still greater than the flicker effect threshold F _a , then increase the brightness value of the road environment of the road section or The illuminance value B may be to increase the brightness of at least one auxiliary light source.
