[0002] With the development of urban transportation, traffic supervision has become increasingly prominent. Traditional traffic supervision typically employs two methods. The first is manual supervision, such as deploying additional personnel to supervise intersections. However, this method relies heavily on manpower, significantly increasing labor costs. Furthermore, manual supervision is affected by weather, the availability of personnel, and their physical condition; moreover, it raises concerns about the personal safety of traffic supervisors. The second method relies on surveillance equipment at various intersections. However, these devices usually only serve a recording function, lacking other functions such as public warnings. Their monitoring angles and ranges are limited and fixed. Adding other functions would involve equipment upgrades or even modifications to municipal infrastructure, a complex process. Therefore, developing a multifunctional intelligent device that can be flexibly applied, replace manual traffic supervision, and simultaneously provide public warnings and video surveillance has become an urgent problem to solve.

[0062] This application provides a multi-functional intelligent monitoring and warning vehicle.

[0063] Please see Figures 1 to 9In one embodiment, this multi-functional intelligent monitoring and warning vehicle is used for automatically monitoring traffic conditions and issuing warnings. Specifically, the multi-functional intelligent monitoring and warning vehicle includes a vehicle body, a warning device, and a monitoring device. The vehicle body includes a frame 110, a shell 120 covering the frame 110, and multiple wheels spaced apart at the bottom of the frame 110. The shell 120 includes an upper shell 121 and a lower shell 122 connected vertically. The upper shell 121 forms a hollow upper cavity, and the lower shell 122 forms a hollow lower cavity.

[0064] Based on this design, in this embodiment, the multi-functional intelligent monitoring and warning vehicle can be pushed to a predetermined location. Then, upon activation, the control system receives the playback information and analyzes and processes it to generate corresponding video and audio information. After receiving the video and audio information, the warning device connected to the control system displays the corresponding images on the screen 210 located on the front of the vehicle's upper shell 121, such as, but not limited to, images or videos containing traffic safety promotion or warnings. Simultaneously, the speaker 220 emits corresponding sound effects, thus achieving the function of traffic warning and promotion. At the same time, the camera 310 located on the upper end of the support column 320 behind the screen 210 also captures and monitors traffic conditions, and the captured information can be uploaded to the corresponding cloud platform server via a wireless network, thereby achieving the function of traffic monitoring. Therefore, compared with existing traffic supervision and warning publicity methods, this multi-functional intelligent monitoring and warning vehicle can not only replace manual supervision to reduce labor costs, but also realize multiple functions such as video and audio combined warning publicity and shooting monitoring. In addition, since the multi-functional intelligent monitoring and warning vehicle can be arranged at predetermined traffic intersections according to the monitoring plan and can be freely withdrawn after completing the publicity, warning and monitoring functions, the use of this multi-functional intelligent monitoring and warning vehicle is also very flexible and can better meet various traffic supervision, warning and publicity needs.

[0065] It should be noted that the application scenarios of this multi-functional intelligent monitoring and warning vehicle are not limited to traffic intersections, but can also be applied to indoor scenarios such as parks or public places. In this application, the content displayed on the screen 210 of this multi-functional intelligent monitoring and warning vehicle can be images or videos, mainly warning and educational content on traffic rules and safety, to serve as a warning and publicity tool. The data information corresponding to these images and videos is usually obtained from the corresponding cloud platform server via wireless network, or from external storage such as, but not limited to, USB flash drives. The monitoring images or videos captured by the camera 310 can be uploaded to the cloud platform server, and then available for retrieval and reference by traffic supervision departments.

[0066] Please see Figures 3 to 6In this embodiment, the multi-functional intelligent monitoring and warning vehicle also includes an inner bracket 130 built into the mounting cavity. The inner bracket 130 is located behind the display screen 210. The inner bracket 130 includes an upper plate 131, a lower plate 132, and multiple legs 133. The bottom end of the legs 133 is fixed to the bottom surface of the lower cavity. The upper plate 131 and the lower plate 132, which are spaced apart vertically, are both fixed to the legs 133. The upper plate 131 and the lower plate 132 are both located in the upper cavity. The support assembly is located behind the inner bracket 130. The multi-functional intelligent monitoring and warning vehicle also includes a power supply 420 and a charging assembly. The control system includes an industrial computer 430, an electronic vehicle identification tag reader 440, and a remote controller 450. The electronic vehicle identification tag reader 440 and the industrial computer 430 are fixedly installed on the upper surface of the upper plate 131, the power supply 420 is installed on the upper surface of the lower plate 132, and the remote controller 450 and the main control board 410 are installed on the lower surface of the lower plate 132. The charging assembly includes a charger 461 and an energy storage battery 462.

[0067] Please see Figure 1In this embodiment, the display screen 210 includes a screen body and a screen frame. The screen body is fixed inside the screen frame, and the screen frame is fixedly connected to the front side of the upper shell 121. Here, the front side of the upper shell 121 has a mounting opening, and the screen body can be connected to the upper shell 121 via the rigid screen frame; that is, the periphery of the screen frame is connected to the edge of the mounting opening. The rear of the screen body is hollow, forming part of the upper cavity, which facilitates heat dissipation of the display screen 210. Further, as... Figure 6 As shown, the multi-functional intelligent monitoring and warning vehicle also includes a cooling fan 500, and the vehicle body includes a front mounting plate 140, which is fixed to the front area of ​​the frame 110. A speaker 220 is fixed to the front mounting plate 140 and located below the front of the display screen 210. The cooling fan 500 is mounted on the frame 110, built into the lower cavity, and located below the display screen 210, between the speaker 220 and the energy storage battery 462. Specifically, in this embodiment, the display screen 210 is slightly tilted backward, and two cooling fans 500 are provided, spaced apart horizontally. Two speakers 220 are also provided, also spaced apart horizontally. It can be understood that the placement of the cooling fans 500 can simultaneously address the heat dissipation of the display screen 210, the speaker 220, the charging components, and the various components on the rear inner bracket 130, effectively further improving the overall heat dissipation effect.

[0068] Please see Figures 2 to 9In this embodiment, the vehicle body also includes a handlebar 610 and a release-to-stop device 620 linked to the handlebar; the handlebar 610 is located at the rear end of the upper shell 121; the handlebar 610 includes a handlebar 611 and two oppositely arranged handlebar connectors 612, the two ends of the handlebar 611 are respectively fixedly connected to the two opposite handlebar connectors 612, the two handlebar connectors 612 are respectively located on the left and right sides of the upper shell 121, and are movably connected to the release-to-stop device. The wheels include two rear wheels 152 located at the rear of the frame 110 and two front wheels 151 located at the front of the frame 110; the release-to-stop device includes a rotation transmission component 621, a pull rod 622, a first locking gear 623, a second locking gear 624, a second locking member 625, a first locking member 626, a linkage rod, and a second elastic member 627; one end of the rotation transmission component 621 is connected to the handle connector 612, and the other end of the rotation transmission component 621 extending into the upper housing 121 is connected to the upper end of the pull rod 622; the lower end of the pull rod 622 extends downward from the mounting cavity to the side of the rear wheels 152, and the first locking member 626 is provided with... At the lower end of the pull rod 622, a first locking gear 623 is located above and connected to the rear wheel 152. The outer edge of the first locking gear 623 is provided with a plurality of first locking grooves 628 evenly spaced along the circumference. The second locking gear 624 is connected to the inner side of the front wheel 151. The outer edge of the second locking gear 624 is provided with a plurality of second locking grooves 629 evenly spaced along the circumference. On the same side, a second elastic member 627 is sleeved on the second locking member 625. One end of the second locking member 625 faces the second locking groove 629, and the other end of the second locking member 625 is synchronously linked with the pull rod 622 through a linkage rod. When the handle 611 is pressed down, the rotating transmission component 621 drives the pull rod 622 upward, causing the first locking component 626 to disengage from the first locking groove 628, and the second locking component 625 to simultaneously retract inward and disengage from the second locking groove 629. Both the front wheel 151 and the rear wheel 152 are in a movable state. When the handle 611 is released and in the spring-up state, the rotating transmission component 621 drives the pull rod 622 downward, causing the first locking component 626 to engage downward in the first locking groove 628. At the same time, the first locking component 626 extends outward and engages in the second locking groove 629, and both the front wheel 151 and the rear wheel 152 are in a locked and stationary state. In other words, when the multi-functional intelligent monitoring and warning vehicle is being pushed, the handle 611 needs to be pressed down, and then the handle connector 612 and the spring drive the rotating transmission component 621 to move upward. This causes the rotating transmission component 621 to drive the pull rod 622 to rise, so that the first locking component 626 moves upward and disengages from the first locking groove 628 of the first locking gear 623. In this way, the rear wheel 152 can move freely. At the same time, the rise of the pull rod 622 also drives the linkage rod to cause the second locking component 625 to retract and disengage from the second locking groove 629. In this way, the front wheel 151 can move.Specifically, since the rear wheel 152 is connected to the frame 110 via a 360-degree rotatable rear wheel 152 bracket, and the first locking gear 623 is located above the rear wheel 152, and the outer edge of the first locking gear 623 is provided with a plurality of first locking grooves 628 evenly spaced circumferentially, the first locking member 626 can extend into or retract from the corresponding first locking groove 628 no matter what angle the rear wheel 152 rotates to; the end of the second locking member 625 away from the front wheel 151 is fitted with a spring, i.e., a second elastic member 627, to realize the real-time elastic locking or retraction of the second locking member 625. Here, the first locking member 626 is integrally formed with the lower end of the pull rod 622. Of course, in other embodiments, the first locking member 626 can also be made separately and then connected to the pull rod 622. Once the multi-functional intelligent monitoring and warning vehicle is pushed to the predetermined position, the handle lever 611 is released. The handle connector 612 and spring drive the rotating transmission component 621 downwards, causing the pull rod 622 to descend. The first locking component 626 moves downwards and locks into the corresponding first locking groove 628, thus stopping the rear wheel 152. Simultaneously, the second locking component 625 also extends outwards elastically and locks into the corresponding second locking groove 629, stopping the front wheel 151 as well. Furthermore, upper limit components 631 and lower limit components 632 are provided on the left and right side plates of the upper shell 121. The swing range of the handle connector 612 is between the upper limit component 631 and the lower limit component 632, ensuring that the extension and retraction range of the first locking component 626 and the second locking component 625 are within a predetermined range, thus ensuring the smooth implementation of the release-to-stop function.

[0069] Please see Figure 3 and Figure 4 In this embodiment, the support assembly further includes a support base 340 and a cable reel 330. The support column 320 includes an outer support tube and an inner support tube. The inner support tube is sleeved within the outer support tube and can slide up and down relative to the outer support tube. The support legs 133 of the support base 340 are fixed to the bottom surface of the lower cavity. The lower end of the outer support tube is fixed to the support base 340. The cable reel 330 is located beside the support base 340 and housed in the lower cavity. The connecting cable of the camera 310 passes through the internal cavity of the inner support tube, exits from the support base 340, and is wound onto the cable reel 330. It can be understood that this structural arrangement allows the height of the support column 320 to be adjusted according to requirements, i.e., the height of the camera 310 is adjustable, thereby achieving better monitoring and shooting height and angle. Meanwhile, the connecting wires of various components installed on the upper end of the support column 320, such as the camera 310, can be housed in the internal cavity of the inner tube of the support. Since the height of the support column 320 is adjustable, the excess part of the connecting wire to adapt to the height adjustment can be wound onto the winding reel 330, and then extended from the winding reel 330 to connect with components such as the main control board 410.

[0070] Furthermore, such as Figures 1 to 4 As shown, in this embodiment, the warning device also includes a flashing light 700, which is located at the top of the camera 310 and is connected to the main control board 410. Here, the flashing light 700 primarily serves to provide a warning through flashing light. Furthermore, its location at the top of the camera 310, i.e., the highest point of the vehicle, makes the warning effect more obvious and does not adversely affect the camera 310's recording and monitoring capabilities.

[0071] However, this design is not limited to this. In another embodiment, the monitoring device also includes a pan-tilt unit 800, which is mounted on the upper end of the support assembly. The camera 310 is mounted on the pan-tilt unit 800, and the pan-tilt unit 800 is connected to the control system to drive the camera 310 to rotate at a predetermined angle, achieving 360-degree rotation of the camera 310. The pan-tilt unit 800 also contains a thermal imaging module and / or a ranging module. It can be understood that by adding the pan-tilt unit 800, the camera 310 can achieve 360-degree all-around monitoring of the surrounding environment, greatly improving monitoring performance. Moreover, the pan-tilt unit 800 contains various functional modules, such as, but not limited to, a thermal imaging module and a ranging module, enabling video monitoring combined with thermal imaging and ranging functions, thereby further expanding the practical functions of this multi-functional intelligent monitoring and warning vehicle.

[0072] This application also proposes a control method for a multi-functional intelligent monitoring and warning vehicle. In one embodiment, the control method for the multi-functional intelligent monitoring and warning vehicle is based on the aforementioned multi-functional intelligent monitoring and warning vehicle and includes the following steps:

[0073] S1. Park the multi-functional intelligent monitoring and warning vehicle at the designated location, and the multi-functional intelligent monitoring and warning vehicle will enter the positioning state;

[0074] S2. The multi-functional intelligent monitoring and warning vehicle has a controlled activation of the warning device and the monitoring device. The warning device includes a display screen 210 and a speaker 220, and the monitoring device includes a camera 310.

[0075] S3. When the warning device is in operation, the warning image is played on the display screen 210 and the warning sound is played simultaneously through the speaker 220; when the monitoring device is in operation, the surrounding environment is captured and monitored in real time through the camera 310.

[0076] In the above control method, firstly, the multi-functional intelligent monitoring and warning vehicle needs to be parked at a predetermined location in the deployment plan, such as a traffic intersection, and it needs to be confirmed that the multi-functional intelligent monitoring and warning vehicle at that predetermined location is in a positioning state. After confirming that the location is correct and in a positioning state, the warning device and the monitoring device can be activated to achieve the functions of publicity and warning and monitoring respectively. It has the advantages of replacing manual supervision to reduce costs, being practical and flexible, and simultaneously realizing multiple functions such as video and audio combined warning publicity and shooting monitoring.

[0077] Furthermore, in this embodiment, the step of parking the multi-functional intelligent monitoring and warning vehicle at a predetermined location and the multi-functional intelligent monitoring and warning vehicle entering the positioning state includes the following steps:

[0078] S11. Hold and press the handle 610 of the multi-functional intelligent monitoring and warning vehicle, push the multi-functional intelligent monitoring and warning vehicle to the predetermined position, and then release the handle 610. The release-stop device will lock the wheels to achieve the release-stop function.

[0079] S12. The position sensor installed in the multi-functional intelligent monitoring and warning vehicle detects and acquires position information, and sends the position information to the corresponding cloud platform server multiple times at preset intervals.

[0080] S13. The cloud platform server will receive the location information and compare it with the pre-stored location range information. If the location information is within the range defined by the pre-stored location range information, it will be determined that the multi-functional intelligent monitoring and warning vehicle is in the correct location. If the location information sent multiple times is consistent, it will be determined that the multi-functional intelligent monitoring and warning vehicle is stationary.

[0081] If the vehicle is determined to be in the correct location and stationary at the same time, the cloud platform server determines that the multi-functional intelligent monitoring and warning vehicle has entered the positioning state; if the multi-functional intelligent monitoring and warning vehicle cannot be determined to be in the correct location and / or cannot be determined to be stationary, the cloud platform server sends an abnormal warning message.

[0082] In other words, once the vehicle is pushed to the predetermined position and stopped by the release mechanism, the position information detected by the position sensor is transmitted to the corresponding cloud platform server to determine whether it is in the correct predetermined position. Then, the consistency of multiple transmitted position information is used to determine if it is stationary. If both conditions are met, it means the multi-functional intelligent monitoring and warning vehicle is in the correct position and stationary, and it can be determined that the multi-functional intelligent monitoring and warning vehicle has entered the positioning state. If either condition is not met, or both are not met, it is determined to be an error, and the cloud platform server sends an abnormality warning message to the staff so that they can make adjustments until both conditions are met simultaneously. Here, the position sensor includes, but is not limited to, the vehicle electronic tag reader 440, etc. The pre-stored position information can be pre-set via computer or network, or it can be stored in the cloud platform server based on the first received position information, after confirmation by the staff, plus reasonable position range data as pre-stored position range information.

[0083] Furthermore, in this embodiment, the control method for the multi-functional intelligent monitoring and warning vehicle also includes the following steps:

[0084] During the operation of the multi-functional intelligent monitoring and warning vehicle, the position sensor continuously detects and acquires position information, and sends the position information to the cloud platform server multiple times at preset intervals.

[0085] If the location information received by the cloud platform server is inconsistent with the location information received later, it is determined that the multi-functional intelligent monitoring and warning vehicle has collided or moved, and the cloud platform server sends location anomaly information.

[0086] It is understandable that since this multi-functional intelligent monitoring and warning vehicle is usually placed at traffic intersections, there may be special circumstances such as collisions. After these circumstances occur, its location information will change. By continuously monitoring the location in real time, the abnormal situation can be detected as soon as possible and then reported to the staff, who will then handle the abnormality.

[0087] Furthermore, in this embodiment, the control system includes a main control board 410 and a remote controller 450. The main control board 410 includes a microcontroller; the multi-functional intelligent monitoring and warning vehicle has an external interface for inserting external storage.

[0088] The operation of the warning device, including projecting a warning image on the display screen 210 and projecting a warning sound through the speaker 220, comprises the following steps:

[0089] The control system determines whether the multi-functional intelligent monitoring and warning vehicle is in wireless remote control mode or offline control mode.

[0090] In wireless remote control mode, the remote controller 450 receives playback information wirelessly transmitted from the cloud platform server, and the microcontroller analyzes and processes the playback information to form video and audio information; or, in offline control mode, the main control board 410 reads the playback information from the external storage inserted into the external interface, and the microcontroller analyzes and processes the playback information to form video and audio information.

[0091] Video information is transmitted to display screen 210 to play the warning image; audio information is transmitted to speaker 220 to play the corresponding warning sound synchronously.

[0092] The steps for the monitoring device to operate and achieve real-time monitoring of the surrounding environment through camera 310 include the following:

[0093] The control system determines whether the multi-functional intelligent monitoring and warning vehicle is in wireless remote control mode or offline control mode.

[0094] In wireless remote control mode, the monitoring information captured by camera 310 is sent to the cloud platform server via remote controller 450; or, main control board 410 sends rotation control information to pan-tilt 800, pan-tilt 800 controls camera 310 to rotate according to the rotation control information. At the same time, the monitoring information captured by camera 310, the thermal imaging information obtained by thermal imaging module on pan-tilt 800, and the distance information obtained by ranging module on pan-tilt 800 are all sent to the cloud platform server via remote controller 450.

[0095] In other words, during the actual operation of the multi-functional intelligent monitoring and warning vehicle, different information transmission and storage paths are implemented depending on whether it is connected to the network. When connected to the network (i.e., in wireless remote control mode), the playback information is received from the cloud platform server via the remote controller 450, which includes, but is not limited to, a 4G network transmission module. In offline control mode, the playback information is obtained from external storage devices such as, but not limited to, USB flash drives, via an external interface. Then, the microcontroller on the main control board 410 analyzes and processes the received playback information into video and audio information, and sends them to the display screen 210 and the speaker 220 respectively to simultaneously play the warning images and sound effects. While issuing warnings, various data, such as information captured by the camera 310 and information acquired by various functional modules on the pan-tilt unit 800, can be sent to the corresponding cloud platform server via the remote controller 450.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
