[0038] Specifically: The top of the display screen 21 is equipped with an audible and visual alarm 22, which is electrically connected to the processor. That is, after the processor receives information that a pedestrian is running a red light, it controls the audible and visual alarm 22 to light up and sound an alarm to remind the pedestrian not to run a red light.

[0039] In an optional implementation of this embodiment, refer to Figure 3 and Figure 6 The housing structure 1 includes an outer shell 11 and a guide assembly 12. The outer shell 11 is used to be laid on one side of the sidewalk 4. The guide assembly 12 is provided inside the outer shell 11 along its extension direction, and the outer shell 11 has a first groove 111. The moving structure 3 is connected to the guide assembly 12, and the moving structure 3 passes through the first groove 111 and is connected to the warning structure 2.

[0040] Specifically: the outer shell 11 is a cuboid shell structure, and it is embedded in one side of the sidewalk 4 along the extension direction of the sidewalk 4. The guide component 12 is located inside the outer shell 11 along the length direction of the outer shell 11, and the two ends of the guide component 12 are respectively connected to the two end faces of the outer shell 11. The top of the outer shell 11 is provided with a first groove 111 along its length direction. The first groove 111 is a through groove. The moving structure 3 can move along the guide component 12, and the moving structure 3 passes through the first groove 111 and connects with the warning structure 2. That is, the moving range of the warning structure 2 is the length range of the first groove 111, and the length of the first groove 111 matches the length of the sidewalk 4.

[0041] The bottom of the outer casing 11 has a through hole, and the lower part of the outer casing 11 has a space to facilitate drainage, and fallen particles will also fall into the space at the lower end of the outer casing 11.

[0042] Furthermore, referring to Figure 4 and Figure 5 The guide assembly 12 includes a guide square tube 121 and a rack 122. The guide square tube 121 is connected to the outer shell 11 along the extension direction of the outer shell 11. The rack 122 is disposed on the inner wall of the guide square tube 121 along the extension direction of the guide square tube 121. The moving structure 3 includes a moving component 31, a servo motor 32 and a gear 33.

Correspondingly, the moving component 31 is provided with a servo motor 32, which is electrically connected to the motor controller. The processor transmits the signal to the motor processor, which then controls the servo motor 32 to start. When the servo motor 32 starts, it drives the gear 33 to rotate, and the gear 33 moves on the rack 122 to move the servo motor 32 and the moving component 31, thereby realizing the synchronous movement of the warning structure 2 connected to the moving component 31. Since the servo motor 32 can rotate forward and reverse, the gear 33 can move forward or backward on the rack 122.

[0044] Furthermore, referring to Figure 4 and Figure 5The guide square tube 121 has a second slide groove 1211 along its extension direction; the moving component 31 includes a moving block 311, a transmission connecting frame 312 and a connecting block 313.

The connecting block 313 is connected to the connecting stabilizing block 26, and the connection method can be detachable connection or welding, etc.

[0046] Furthermore, referring to Figure 4 The moving block 311 has a receiving slot 3111, which contains a servo motor 32 and a gear 33.

[0047] Specifically: The top of the moving block 311 is provided with a receiving groove 3111. One side of the groove wall of the receiving groove 3111 is connected to the servo motor 32, and the output shaft of the servo motor 32 is connected to the gear 33. The other end of the output shaft can be rotatably connected to the other side of the groove wall of the receiving groove 3111 through a bearing, so that the rotating shaft can be more stable during rotation.

[0048] In an optional implementation of this embodiment, refer to Figure 4 The moving component 31 also includes a roller 314, which is rotatably connected to the moving block 311 and is used to roll along the inner wall of the guide square tube 121.

[0049] Specifically: The bottom of the moving block 311 can be provided with two sets of rollers 314, and the two sets of rollers 314 are located on both sides of the second slide groove 1211 respectively. The rollers 314 roll along the bottom of the inner wall of the guide square tube 121, and each set of rollers 314 can have two rollers 314; by setting the rollers 314, the moving block 311 can move more smoothly.

[0050] In an optional implementation of this embodiment, refer to Figure 4 and Figure 5 The guide assembly 12 also includes a stabilizing slide bar 123, which is disposed inside the guide square tube 121 along the extension direction of the guide square tube 121; the moving block 311 is slidably connected to the guide square tube 121.

The two ends of the stabilizing slide bars 123 are respectively connected to the two ends of the guide square tube 121. Both sets of stabilizing slide bars 123 pass through the moving block 311, and the moving block 311 can move along the stabilizing slide bars 123, making the moving block 311 more stable when moving.

[0052] Both ends of the pedestrian walkway 4 are equipped with red light waiting areas 6, and each red light waiting area 6 is equipped with an illumination light 5. The illumination light 5 is connected to the controller via an infrared switch, and the infrared switch is located at both ends of the pedestrian walkway 4. The controller is also connected to a light sensor, and the illumination light 5 is also controlled by the data from the light sensor.

[0053] It should be noted that the processor, data processing module, motor controller, data acquisition module, lighting lamp 5, infrared switch, and light sensor are all existing devices on the market, and the model can be selected according to actual usage needs.

[0054] During use, the housing structure 1 is installed in pairs at each intersection, located on both sides of the intersection. When pedestrians cross the intersection normally according to traffic rules, the warning structure 2 will not be triggered, but will be located on both sides of the intersection, displaying the words "Streetlight Passage" on both sides of the display screen 21. When a pedestrian runs a red light at an intersection, the high-definition camera 23 will collect the pedestrian's position at the intersection, and the processor will analyze the traffic light situation in real time. When it is determined that a pedestrian has run a red light, the audible and visual alarm 22 will be activated first to remind the pedestrian not to run a red light. If the pedestrian still continues to run a red light, the processor will... The system controls the rotation of the servo motor 32 closest to the pedestrian running the red light via a motor controller. The rotation speed of the servo motor 32 is adjusted according to the pedestrian's walking speed, thereby displacing the moving component 31 and the upper warning structure 2. This ensures that the warning structure 2 is always aligned with the pedestrian running the red light. Simultaneously, the display screen 21 displays a warning message: "Pedestrian running the red light, please be careful!" This serves as a reminder to oncoming vehicles, preventing traffic accidents and also serves as a public warning, using public opinion to improve the phenomenon of pedestrians not obeying traffic rules, thus greatly reducing the probability of accidents. When the pedestrian retreats or crosses the pedestrian crossing 4, the walking warning structure 2 returns to its original position as the servo motor 32 reverses. At night, when a pedestrian crosses one of the pedestrian crossings 4, the corresponding lighting 5 illuminates the pedestrian crossing 4, revealing the legs of the pedestrian and allowing drivers to see them, thus preventing accidents and making it safer for pedestrians crossing intersections.
