Embodiment 1

[0037] When implementing, follow these steps:

[0038] 1) When the red light signal light 102 in the signal light is on, the camera and radar in the perception system 106 will feed back to the traffic light control system 107 according to the collected information, and the traffic light control system 107 will control the projection device 101. The no-pass image in the projection image 105 is projected through the projection lens 100, and the spectroscopic system 108 divides the no-pass image into a vertical direction and a horizontal direction for projection, and the reflector on the spectroscopic system 108 adopts a plane reflector;

[0039] 2) When the yellow light signal light 103 in the signal light is on, the camera and radar in the perception system 106 will feed back to the traffic light control system 107 according to the collected information, and the traffic light control system 107 will control the projection device 101. The projected image 105 is projected out thr...

[0042] When implementing, follow these steps:

[0043] 1) When the red light signal light 102 in the signal light is on, the camera and radar in the perception system 106 will feed back to the traffic light control system 107 according to the collected information, and the traffic light control system 107 will control the projection device 101. In the projection image 105, the no-pass image is projected through the projection lens 100, and the spectroscopic system 108 divides the no-pass image into a vertical direction and a horizontal direction for projection. aspheric mirror;

[0044] 2) When the yellow light signal light 103 in the signal light is on, the camera and radar in the perception system 106 will feed back to the traffic light control system 107 according to the collected information, and the traffic light control system 107 will control the projection device 101. The first-class image in the projected image 105 is projected through the projection lens 100. The sp...

Abstract

The invention relates to an intelligent traffic projection street lamp, which comprises signal lamps, the signal lamps comprise a red light signal lamp (102), a yellow light signal lamp (103) and a green light signal lamp (104), the signal lamps are connected to a traffic signal lamp control system (107), and the signal lamps are provided with a sensing system (106) and a projection device (101). The traffic signal lamp control system (107) is connected to the sensing system (106) and the projection device (101), the projection device (101) is provided with a projection lens (100), the projection lens (100) can project a road surface projection image (105) onto a road surface, and the traffic signal lamp control system (107) can display red, yellow and green light signals on one hand, and can also display the road surface projection image (105) on the other hand; meanwhile, according to signals fed back by the sensing system and the traffic signal control system, different symbols can be projected on the road surface, and drivers and pedestrians are reminded of different traffic guidance and warning information.

Description

technical field [0001] The invention relates to the field of smart traffic lights, in particular to a smart traffic projection street light. Background technique [0002] At present, traditional traffic lights are used to display red, yellow and green light signals at intersections, respectively prompting pedestrians and vehicles to stop, wait and pass, but some special objects, such as drivers or pedestrians with color weakness or color blindness, cannot be identified. Therefore, a new technical solution is required to solve the above technical problems. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention proposes a smart traffic projection street lamp, which can display red, yellow and green light signals on the one hand, and at the same time, according to the feedback signals of the perception system and the traffic signal control system, can project different lights on the road surface. , which prompts drivers and pede...
