Description

Technical Field

[0001] This invention relates to the field of vehicle positioning equipment, and particularly to a vehicle positioning device based on 5G communication. Background Technology

[0002] 5G networks, characterized by high speed and low latency, can provide high-precision vehicle positioning services. Through 5G networks, vehicles can receive information from multiple base stations, and by calculating and comparing signal propagation time or phase differences, positioning accuracy at the centimeter or even millimeter level can be achieved. 5G communication enables real-time information exchange between vehicles and between vehicles and infrastructure.

[0003] Currently, in urban traffic, some traffic lights often require a specific waiting time before turning green. Even when there are no vehicles on the green light, the red light on the other side still requires a pre-set waiting time. Traffic lights cannot flexibly change according to the length of vehicles waiting at each intersection, causing many people to waste a lot of time waiting for traffic lights. Reasonably scheduling the lighting times of traffic lights in each direction based on the length of vehicles queuing at each intersection would not only save a lot of queuing time but also improve traffic order in each city. Although manual adjustment can alleviate the problem temporarily, having staff at each intersection would waste a lot of manpower, and peak traffic flow changes over time, with real-time traffic conditions constantly changing, making manual adjustment inflexible. Therefore, we need more intelligent equipment to automatically monitor traffic flow.

[0004] Therefore, we propose a vehicle positioning device based on 5G communication. Summary of the Invention

[0005] The main objective of this invention is to provide a vehicle positioning device based on 5G communication, which can effectively solve the problems mentioned in the background art of insufficient flexibility in traffic light switching and high cost and inflexibility of manual adjustment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] The vehicle positioning device based on 5G communication includes a carrier plate, a protective cover fixedly installed on the upper end of the carrier plate, and a control module. A servo motor and an infrared rangefinder are installed inside the protective cover. A support cylinder is located in the middle of the lower end of the carrier plate. A horizontal crossbar and a meshing helical gear for power transmission are installed inside the support cylinder. A positioning plate is fixedly connected to the lower end of the support cylinder. Four sets of measurement conversion mechanisms are arranged between the carrier plate and the positioning plate. Each measurement conversion mechanism includes an adjusting rod and a trigger push rod. A patrol switching mechanism is installed at the end of the adjusting rod away from the carrier plate. The patrol switching mechanism includes a camera and a drive gear. A matching guide groove is provided on the positioning plate to facilitate the sliding of the adjusting rod. The control module is fixedly installed at the lower end of the positioning plate.

[0008] Preferably, a transmission rod is fixedly connected to the output end of the servo motor, and a transmission gear is fixedly connected to the lower part of the outer surface of the transmission rod. The transmission rod is movably inserted into the bottom wall of the support cylinder. Four sets of evenly distributed horizontal crossbars are movably inserted into the upper part of the outer surface of the support cylinder. One end of each horizontal crossbar located inside the cavity of the support cylinder is fixedly connected to a meshing helical gear. The meshing helical gear meshes with the transmission gear. When the servo motor is working, the transmission rod causes the transmission gear to rotate, and the rotation of the transmission gear causes the meshing helical gear to rotate accordingly. The rotation of the horizontal crossbars provides the power to adjust the inclination of the adjustment rod.

[0009] Preferably, there are four sets of infrared rangefinders, and each set of infrared rangefinders is electrically connected to a corresponding camera and a first contact limiter. The infrared rangefinders, together with the reflector and the first contact limiter, measure the length of traffic flow waiting at each intersection for traffic lights.

[0010] Preferably, the measurement conversion mechanism includes a positioning connecting block, an adjusting rod movably connected to the side of the positioning connecting block near the support cylinder, a trigger push rod movably connected to the upper part of the adjusting rod, a limit plate slidably connected to the upper part of the trigger push rod, the adjusting rod being rotatable about a central axis connected to the positioning connecting block, and the upper part of the adjusting rod being movably connected to the trigger push rod. By moving the horizontal position of the trigger push rod, the adjusting rod rotates, thereby adjusting the camera angle of the camera mounted on the adjusting rod, facilitating the camera to detect the overall length of vehicles waiting at the traffic light at the corresponding intersection. The horizontal movement of the reflector causes the trigger push rod to move horizontally, forcing the adjusting rod to rotate, thus adjusting the angle of the camera. The rotating lever adjusts the maximum shooting distance of the camera, and the distance the trigger push rod moves is proportional to the maximum shooting distance of the camera. The reflector detects the distance the trigger push rod moves using an infrared rangefinder. After detecting the distance the reflector moves, the infrared rangefinder transmits a signal to the control module. The control module converts the distance the reflector moves into the length of the traffic flow waiting at the traffic lights at the intersection. This is then compared with the speed of the traffic flow detected by the speed detection component in the control module to adjust the reasonable lighting time of the traffic lights at each intersection. This can improve the level of urban intelligence and provide citizens with a more convenient, safe, and comfortable urban life.

[0011] Preferably, the measurement conversion mechanism further includes a transmission threaded rod, which is threadedly and movably inserted into the upper part of the trigger push rod. The upper end of the trigger push rod passes through the limiting horizontal plate and is fixedly connected to a reflector. The end of the transmission threaded rod away from the support cylinder is movably mounted on the side wall of the positioning connecting block, and the end of the transmission threaded rod near the support cylinder is fixedly connected to the horizontal crossbar. The transmission threaded rod is threaded into the trigger push rod, and by controlling the forward and reverse rotation of the transmission threaded rod, the trigger push rod can slide within the groove on the limiting horizontal plate. The movement of the trigger push rod causes the reflector mounted on it to move. The displacement magnitude under different states is then measured by an infrared rangefinder and transmitted to the control module, which then... The control module analyzes the length of vehicles waiting at each intersection's traffic lights and sends this information to the control center via 5G communication. The control center adjusts the duration of the traffic lights at each intersection based on real-time conditions. The adjusting rod can slide on the guide groove with its own length as the radius, centered on the central axis connected to the positioning block, facilitating adjustment of the camera's shooting angle. This allows the camera to capture the last vehicle waiting at each intersection. The signal of the positions of the first and last vehicles in the entire traffic flow waiting at the traffic lights is transmitted to the infrared rangefinder. Upon receiving the signal, the infrared rangefinder, in conjunction with the reflector, detects the distance the trigger push rod has moved.

[0012] Preferably, an arc-shaped platform is fixedly connected to the upper end of the positioning disk. Four sets of evenly distributed matching guide grooves are formed on the upper part of the outer surface of the arc-shaped platform. A set of first contact limiters are movably installed in the upper and lower parts of the inner cavity of the matching guide groove. The first contact limiters are electrically connected to the infrared rangefinder. An annular toothed groove is formed on the outer side of the upper end of the arc-shaped platform. The annular toothed groove cooperates with the drive gear. The matching guide groove is arc-shaped. The adjusting rod can slide in the arc-shaped groove of the matching guide groove with the central axis at the connection point with the positioning connecting block as the center. When the trigger push rod moves, it can push the adjusting rod to rotate. The rotation of the adjusting rod can adjust the shooting angle of the camera fixedly installed on it. When the device is installed, the position of the first contact limiter is the limit position where the adjusting rod can move upward. When the adjusting rod touches the first contact limiter, the farthest distance that the camera can shoot is the waiting line in front of the traffic light. When the adjusting rod moves downward, the farthest shooting distance of the camera increases, which makes it convenient for the camera to shoot the position of the last vehicle waiting at the traffic light at each intersection.

[0013] Preferably, a receiving platform is slidably connected to the outer side of the arc-shaped platform. A mating block is fixedly connected to the upper end of the receiving platform near the side of the arc-shaped platform. A snap-fit ​​groove is provided at the upper end of the mating block. A second contact limiter is fixedly installed on the bottom wall of the inner cavity of the snap-fit ​​groove. When the traffic flow at the intersection is low at night, the control module adjusts this device to enter the patrol mode. The control module controls the servo motor to rotate, causing the adjusting rod to move outward. The lower part of the adjusting rod touches the first contact limiter at the lower part of the guide groove. When the first contact limiter is touched, the power supply to the servo motor is cut off, and feedback is sent to the control module. The control module then controls the drive motor in the patrol switching mechanism to operate. The drive motor drives the drive gear in the adjustment... The slide plate moves within the sliding groove. The upper wall of the sliding groove has meshing toothed grooves, allowing the support plate to slide downwards within the sliding groove. When the support plate descends to the receiving platform, the snap-fit ​​connector engages with the snap-fit ​​groove, triggering the second contact limiter and sending a signal to shut off the drive motor. The control module then controls the servo motor to reverse, causing the adjusting rod to move inwards and disengage the patrol switching mechanism from the adjusting rod. At this time, the drive gear meshes with the annular toothed groove, and the control module controls the drive motor to move, causing the disengaged patrol switching mechanism to perform circular motion on the receiving platform along the annular toothed groove as a circular trajectory. This allows it to patrol the surrounding vehicle conditions and promptly transmit any unexpected vehicle behavior, such as breakdowns or collisions at intersections, to the control center.

[0014] Preferably, the patrol switching mechanism includes a support plate. A snap-fit ​​connector is fixedly installed at one end of the support plate near the guide groove. Multiple evenly distributed cameras are fixedly installed at the end of the support plate away from the support cylinder. An adjustment groove is provided at one end of the adjusting rod near the support plate. The support plate is slidably installed in the adjustment groove. A drive motor is fixedly installed on the side of the support plate within the adjustment groove. A drive gear is fixedly connected to the output end of the drive motor. A meshing tooth groove is provided on the upper wall of the adjustment groove. The drive gear meshes with the meshing tooth groove. The patrol switching mechanism is movably installed in the adjustment groove of the adjusting rod through the support plate and the drive gear. This facilitates adjusting the position of the patrol switching mechanism at the adjusting rod and allows the patrol switching mechanism to be adjusted to patrol mode. This enables the device to patrol intersections at night or when traffic is low, saving energy consumption.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a measurement conversion mechanism, which includes a position connecting block, adjusting rod, trigger push rod, limiting horizontal plate, and transmission threaded rod, the transmission threaded rod is threaded into the trigger push rod. By controlling the forward and reverse rotation of the transmission threaded rod, the trigger push rod slides in the groove of the limiting horizontal plate. The movement of the trigger push rod causes the reflector mounted on it to move. The displacement under different conditions is measured by an infrared rangefinder and transmitted to the control module. The control module analyzes the length of vehicles waiting at each intersection's traffic lights and sends it to the control center via 5G communication. The control center adjusts the duration of the traffic lights at each intersection based on real-time conditions. By locating the length of vehicles queuing at traffic light intersections and combining it with the 5G network for intelligent route planning and navigation, traffic flow and road conditions can be greatly improved, and queuing time can be saved.

[0017] 2. The adjusting rod can slide on the matching guide groove with the central axis connected to the positioning connecting block as the center and the length of the adjusting rod itself as the radius. This facilitates the adjustment of the camera's shooting angle, enabling the camera to capture the last vehicle waiting at each intersection. The signal of the position points of the first and last vehicles in the traffic flow waiting at the traffic light is transmitted to the infrared rangefinder. After receiving the signal, the infrared rangefinder, in conjunction with the reflector, detects the distance the trigger push rod has moved. This distance is compared with the speed of the traffic flow detected by the speed detection meter in the control module to adjust the reasonable lighting time of the traffic lights at each intersection. This can improve the city's intelligence level and provide citizens with a more convenient, safe, and comfortable urban life.

[0018] 3. By setting up a patrol switching mechanism, which includes a support plate, camera, drive motor, drive gear, and connector, the control module adjusts the device to enter patrol mode when traffic flow at intersections is low at night. The detached patrol switching mechanism moves in a circular motion on the support plate along a circular track, patrolling the surrounding vehicle conditions. It promptly transmits unexpected vehicle conditions such as breakdowns or collisions at intersections to the control center. This allows the device to patrol intersections at night or when traffic flow is low, monitoring the real-time traffic conditions at each traffic light intersection, while also saving energy consumption.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-8 As shown, the vehicle positioning device based on 5G communication includes a carrier plate 1, a protective cover 2 fixedly installed on the upper end of the carrier plate 1, and a control module 9. A servo motor 3 and an infrared rangefinder 5 are installed inside the protective cover 2. A support cylinder 4 is located in the middle of the lower end of the carrier plate 1. A horizontal crossbar 41 and a meshing helical gear 42 for power transmission are installed inside the support cylinder 4. A positioning plate 7 is fixedly connected to the lower end of the support cylinder 4. Four sets of measurement conversion mechanisms 6 are arranged between the carrier plate 1 and the positioning plate 7. Each measurement conversion mechanism 6 includes an adjusting rod 62 and a trigger push rod 63. A patrol switching mechanism 8 is installed at the end of the adjusting rod 62 away from the carrier plate 1. The patrol switching mechanism 8 includes a camera 82 and a drive gear 84. A fitting guide is provided on the positioning plate 7 to facilitate the sliding of the adjusting rod 62. The control module 9 is fixedly installed at the lower end of the positioning plate 7 in slot 72. A transmission rod 31 is fixedly connected to the output end of the servo motor 3. A transmission gear 32 is fixedly connected to the lower part of the outer surface of the transmission rod 31. The transmission rod 31 is movably inserted into the bottom wall of the support cylinder 4. Four sets of evenly distributed horizontal crossbars 41 are movably inserted into the upper part of the outer surface of the support cylinder 4. One end of each horizontal crossbar 41 located in the inner cavity of the support cylinder 4 is fixedly connected to a meshing helical gear 42. The meshing helical gear 42 meshes with the transmission gear 32. When the servo motor 3 is working, the transmission rod 31 causes the transmission gear 32 to rotate. The rotation of the transmission gear 32 causes the meshing helical gear 42 to rotate accordingly. The rotation of the horizontal crossbars 41 provides the power to adjust the inclination of the adjusting rod 62.

[0030] There are four sets of infrared rangefinders 5, and each set of infrared rangefinders 5 is electrically connected to the corresponding camera 82 and the first contact limiter 73. The infrared rangefinders 5, together with the reflector 631 and the first contact limiter 73, measure the length of traffic flow waiting at each intersection.

[0031] Example 1

[0032] Please see Figure 1-8 This embodiment provides a technical solution: the measurement conversion mechanism 6 includes a positioning connecting block 61, an adjusting rod 62 is movably connected to the side of the positioning connecting block 61 near the support cylinder 4, a trigger push rod 63 is movably connected to the upper part of the adjusting rod 62, a limit plate 64 is slidably connected to the upper part of the trigger push rod 63, the adjusting rod 62 can rotate about the central axis connected to the positioning connecting block 61, the upper part of the adjusting rod 62 is movably connected to the trigger push rod 63, by moving the position of the trigger push rod 63 in the horizontal direction, the adjusting rod 62 rotates, thereby adjusting the camera angle of the camera 82 installed on the adjusting rod 62, so that the camera 82 can detect the overall length of vehicles waiting at the traffic light at the corresponding intersection, the reflector 631 moves horizontally, so that the trigger push rod 63 moves horizontally, forcing The adjustment rod 62 is rotated, which adjusts the maximum shooting distance of the camera 82. The distance that the trigger push rod 63 moves is proportional to the maximum shooting distance of the camera 82. The reflector 631 can detect the distance that the trigger push rod 63 moves through the infrared rangefinder 5. After the infrared rangefinder 5 detects the distance that the reflector 631 moves, it transmits a signal to the control module 9. The control module 9 converts the distance that the reflector 631 moves into the length of the traffic flow waiting at the traffic light at the intersection. It then compares this with the speed of the traffic flow detected by the speed detection component at the control module 9 to adjust the reasonable lighting time of the traffic lights at each intersection. This can improve the level of intelligence in the city and provide citizens with a more convenient, safe, and comfortable urban life.

[0033] The measurement conversion mechanism 6 also includes a transmission threaded rod 65, which is threadedly inserted into the upper part of the trigger push rod 63. The upper end of the trigger push rod 63 passes through the limiting horizontal plate 64 and is fixedly connected to a reflector plate 631. The end of the transmission threaded rod 65 away from the support cylinder 4 is movably installed on the side wall of the positioning connecting block 61, and the end of the transmission threaded rod 65 near the support cylinder 4 is fixedly connected to the horizontal crossbar 41. The transmission threaded rod 65 is threaded into the trigger push rod 63. By controlling the forward and reverse rotation of the transmission threaded rod 65, the trigger push rod 63 can slide in the groove on the limiting horizontal plate 64. The movement of the trigger push rod 63 causes the reflector plate 631 installed on it to move. The displacement magnitude under different states is then measured by the infrared rangefinder 5 and transmitted to the control module. Block 9, the control module 9 analyzes the length of vehicles waiting at each intersection's traffic light and sends it to the control center via 5G communication. The control center adjusts the duration of the traffic light at each intersection based on the real-time situation. The adjusting rod 62 can slide on the matching guide groove 72 with the central axis connected to the positioning connecting block 61 as the center and the length of the adjusting rod 62 itself as the radius, which facilitates the adjustment of the shooting angle of the camera 82, so that the camera 82 can capture the last vehicle waiting at each intersection's traffic light. The signal of the position points of the first and last vehicles in the entire traffic flow waiting at the traffic light is transmitted to the infrared rangefinder 5. After receiving the signal, the infrared rangefinder 5 cooperates with the reflector 631 to detect the distance the trigger push rod 63 has moved.

[0034] Example 2

[0035] Please see Figure 1-8 This embodiment provides a technical solution based on Embodiment 1: An arc-shaped platform 71 is fixedly connected to the upper end of the positioning disk 7. Four sets of evenly distributed matching guide grooves 72 are formed on the upper part of the outer surface of the arc-shaped platform 71. A set of first contact limiters 73 are movably installed in the upper and lower parts of the inner cavity of the matching guide grooves 72. The first contact limiters 73 are electrically connected to the infrared rangefinder 5. An annular toothed groove 74 is formed on the outer side of the upper end of the arc-shaped platform 71. The annular toothed groove 74 cooperates with the drive gear 84. The matching guide groove 72 is arc-shaped, and the adjusting rod 62 can be adjusted around the central axis at the connection point with the positioning connecting block 61 in the matching guide groove 72. The device slides within the arc-shaped groove. When the push rod 63 moves, it can push the adjusting rod 62 to rotate. The rotation of the adjusting rod 62 can adjust the shooting angle of the camera 82 fixedly mounted on it. When the device is installed, the position of the first contact limiter 73 is the limit position where the adjusting rod 62 can move upward. When the adjusting rod 62 touches the first contact limiter 73, the farthest distance that the camera 82 can shoot is the waiting line in front of the traffic light. When the adjusting rod 62 moves downward, the farthest shooting distance of the camera 82 increases, making it easier for the camera 82 to shoot the position of the last vehicle waiting at each intersection.

[0036] The patrol switching mechanism 8 includes a support plate 81. A snap-fit ​​connector 85 is fixedly installed at one end of the support plate 81 near the guide groove 72. Multiple evenly distributed cameras 82 are fixedly installed at the end of the support plate 81 away from the support cylinder 4. An adjustment groove 621 is provided at the end of the adjusting rod 62 near the support plate 81. The support plate 81 is slidably installed within the adjustment groove 621. A drive motor 83 is fixedly installed on the side of the support plate 81 within the adjustment groove 621. A drive gear 84 is fixedly connected to the output end of the drive motor 83. A meshing tooth groove 622 is provided on the upper wall of the adjustment groove 621, and the drive gear 84 meshes with the meshing tooth groove 622. The patrol switching mechanism 8 is movably installed within the adjustment groove 621 of the adjusting rod 62 via the support plate 81 and the drive gear 84. This facilitates adjusting the position of the patrol switching mechanism 8 at the adjusting rod 62 and allows for easy adjustment to the patrol mode. This enables the device to patrol intersections at night or when traffic is light, saving energy consumption.

[0037] A receiving platform 711 is slidably connected to the outer side of the arc-shaped platform 71. A mating block 712 is fixedly connected to the upper end of the receiving platform 711 near the side of the arc-shaped platform 71. A snap-fit ​​groove 713 is provided on the upper end of the mating block 712. A second contact limiter 714 is fixedly installed on the bottom wall of the inner cavity of the snap-fit ​​groove 713. When the traffic flow at the intersection is low at night, the control module 9 enters the patrol mode by adjusting this device. The control module 9 controls the servo motor 3 to rotate, causing the adjusting rod 62 to move outward. The lower part of the adjusting rod 62 touches the first contact limiter 73 at the lower part of the guide groove 72. When the first contact limiter 73 is touched, the power supply to the servo motor 3 is cut off, and feedback is sent to the control module 9. The control module 9 then controls the drive motor 83 in the patrol switching mechanism 8 to move. The drive motor 83 drives the drive gear 84 in the adjusting slide groove 621. The upper wall of the adjusting slide 621 has a meshing toothed groove 622, which allows the bearing plate 81 to slide downward within the adjusting slide 621. When the bearing plate 81 descends to the receiving platform 711, the snap-fit ​​connector 85 snaps into the snap-fit ​​groove 713, triggering the second contact limiter 714 and sending a signal to shut off the drive motor 83. The control module 9 then controls the servo motor 3 to reverse, causing the adjusting rod 62 to move inward and disengage the patrol switching mechanism 8 from the adjusting rod 62. At this time, the drive gear 84 meshes with the annular toothed groove 74, and the control module 9 controls the drive motor 83 to move, causing the disengaged patrol switching mechanism 8 to move in a circular motion on the receiving platform 711 along the annular toothed groove 74, patrolling the surrounding vehicle conditions and promptly transmitting any unexpected vehicle conditions such as breakdowns or collisions at intersections to the control center.

[0038] Working principle of this invention:

[0039] It should be noted that this invention is a vehicle positioning device based on 5G communication. When installing this device, the first contact limiter 73 is located at the limit position where the adjusting rod 62 can move upward. When the adjusting rod 62 touches the first contact limiter 73, the farthest distance that the camera 82 can capture is the waiting line in front of the traffic light. When the adjusting rod 62 moves downward, the farthest shooting distance of the camera 82 increases. The control module 9 controls the servo motor 3 to work in both forward and reverse cycles periodically. The transmission gear 32 and the meshing helical gear 42 mesh. When the servo motor 3 is working, the transmission gear 32 rotates through the transmission rod 31. The rotation of the transmission gear 32 causes the meshing helical gear 42 to rotate accordingly. The transmission threaded rod 65 is fixed to the horizontal crossbar 41. The transmission threaded rod 65 is threadedly connected to the trigger push rod 63, and the lower part of the trigger push rod 63 is slidably limited to the adjusting rod 62. By controlling the forward and reverse rotation of the transmission threaded rod 65, the trigger push rod 63 can slide within the groove on the limiting plate 64, forcing the adjusting rod 62 to rotate. The rotation of the adjusting rod 62 can adjust the farthest distance of the camera 82's image positioning. The distance the trigger push rod 63 moves is proportional to the farthest distance the camera 82 can capture. The reflector 631 can detect the distance the trigger push rod 63 moves using the infrared rangefinder 5. After detecting the distance the reflector 631 moves, the infrared rangefinder 5 transmits a signal to the control module 9. When the adjusting rod 62 touches the first contact limiter 73, the camera 82 can capture and position the image. The furthest distance is the waiting line in front of the traffic light. As the adjusting rod 62 moves downward, the furthest shooting positioning distance of the camera 82 increases, and the position of the last car waiting at the traffic light at the intersection also becomes farther away. The control module 9 can calculate the length of the traffic flow waiting at the traffic light at the intersection based on the distance moved by the reflector 631 and the signal fed back by the infrared rangefinder 5. This is compared with the speed of the traffic flow detected by the speed detection component at the control module 9 to adjust the reasonable lighting time of the traffic lights at each intersection. When the traffic flow at the intersection is small at night, the control module 9 enters the patrol mode by adjusting the device. The control module 9 controls the servo motor 3 to rotate, causing the adjusting rod 62 to move outward. The movement causes the lower part of the adjusting rod 62 to contact the first contact limiter 73 at the lower part of the guide groove 72. Upon contact, the first contact limiter 73 cuts off the power to the servo motor 3 and sends feedback to the control module 9. The control module 9 then controls the output of the drive motor 83 in the inspection switching mechanism 8 to rotate. The rotation of the drive motor 83 drives the drive gear 84 to move within the adjusting slide 621. The upper wall of the adjusting slide 621 has meshing tooth grooves 622, allowing the support plate 81 to slide downwards within the adjusting slide 621. When the support plate 81 descends to the receiving platform 711 and the locking connector 85 engages with the locking groove 713, the second contact limiter 714 is activated, sending a signal to shut off the drive motor 83. The control module 9 then controls the servo motor 3 to reverse.The adjusting rod 62 is moved inward, causing the patrol switching mechanism 8 to disengage from the adjusting rod 62. At this time, the drive gear 84 meshes with the annular tooth groove 74. The control module 9 controls the drive motor 83 to operate, causing the disengaged patrol switching mechanism 8 to perform circular motion on the receiving platform 711 along the annular tooth groove 74, patrolling the surrounding vehicle conditions. It promptly transmits unexpected vehicle conditions such as breakdowns or collisions at intersections to the control center. When it is necessary to end the patrol mode, the output end of the drive motor 83 rotates, causing the entire... When the inspection switching mechanism 8 moves to the position where it disengages from the adjusting rod 62, the control module 9 controls the servo motor 3 to rotate, causing the adjusting rod 62 to move outward along the direction of the engaging guide groove 72. This engages the meshing tooth groove 622 at the lower part of the adjusting rod 62 with the drive gear 84. The control module 9 then controls the drive motor 83 to rotate, and the drive gear 84 engages with the meshing tooth groove 622, causing the entire inspection switching mechanism 8 to slide upward along the direction of the adjusting slide groove 621, thus readjusting the inspection switching mechanism 8 back onto the adjusting rod 62.
