[0035] like Figure 1 As shown, the present invention proposes an urban road temporary parking emergency handling device, including M warning systems and a control system, and the M warning systems are respectively connected to the control system.

[0036] In this embodiment, the structure of each warning system is the same, and is mainly used to set a warning area at a first distance from the temporarily parked vehicle.

[0037] Each warning system has a unique number, which is associated with the city road it is responsible for; Figure 2 As shown, for example, a city road is divided into M sections, and a warning system is installed in each section (the length can be 500 meters), then the number of the warning systems is {1,2,...,m-1,m}.

[0038] The control system is used to detect temporarily parked vehicles and send a warning signal (first signal) to a corresponding warning system.

[0039] In this embodiment, Figure 3 As shown, the warning system includes a guardrail body 1-1, a sliding assembly 1-2, a mobile robot 1-3, a supporting module, a warning line 1-7 and a warning line storage module 1-8.

[0040] In this embodiment, the structures of the warning systems on both sides are the same, and one side is used as an example. The guardrail body 1-1 (guardrail) is installed on both sides of the urban road; the sliding assembly 1-2 is a two-layer sliding rail groove, which is fixed to the inner side of the top of the guardrail body 1-1 by bolts and nuts; the mobile robot 1-3 is embedded in the sliding assembly 1-2, that is, it slides freely on the sliding assembly 1-2; the mobile robot (1-3) includes a first drive motor, a first tire, a first sub-control unit, a first solar panel, and a first battery. The first electronic control unit and the control system are wirelessly / wiredly connected (the specific structure can be set according to needs, which belongs to conventional technology and is not the focus of the present invention).

[0041] like Figure 4 As shown, a support module is provided on the mobile robot 1-3, and the support module includes a transverse rod 1-4 (hollow cylindrical PC tube), a rotary bearing 1-6, and a support rod 1-5; one end of the transverse rod 1-4 is on the mobile robot 1-3, and the other end of the transverse rod 1-4 is provided with a rotary bearing 1-6 (that is, the other end of the transverse rod 1-4 is connected to the first end of the rotary bearing 1-6), and a support rod 1-5 is provided below the rotary bearing 1-6 (that is, one end of the support rod 1-5 is connected to the second end of the rotary bearing 1-6), and the other end of the support rod 1-5 is in contact with the ground to achieve fixed support. The rotary bearing 1-6 is equipped with an engine and a power supply cable, which are used to drive the transverse rod 1-4 and the support rod 1-5 to extend and retract.

[0042] The lengths of the transverse rods 1-4 and the support rods 1-5 can be freely adjusted. When the support module is in the retracted state, the length of the transverse rods 1-4 is d1 (e.g. 10 cm); when the support module is in the extended state, the length of the transverse rods 1-4 is d2 (e.g. 2 m).

[0043] The mobile robot 1-3 is provided with a micro-microphone 1-9, a micro-speaker 1-10 and a switch button 1-11 on its exterior. The micro-microphone 1-9 is used to record sound; the micro-speaker 1-10 is used to emit sound; the switch button 1-11 is used to close the support module of the mobile robot 1-3 and return the support module to the retracted state.

[0044] In this embodiment, one end of the warning line 1-7 is connected to the other end of the horizontal rod 1-4 through a bayonet slot and a pressure button (i.e., fixed to one end close to the rotating bearing 1-6), and the other end of the warning line 1-7 is connected to the warning line storage module 1-8. The warning line storage module 1-8 includes a second drive motor, a second tire, a second electronic control unit, a second solar panel, a second battery, a rotating machine, and a recovery rod, which are also embedded in the sliding assembly 1-2, i.e., they slide freely on the sliding assembly 1-2; the rotating machine drives the recovery rod to rotate and then drives the warning line 1-7 to be recovered and stored (the structure of the warning line storage module 1-8 can be set as needed, which belongs to conventional technology and is not the focus of the present invention).

[0045] In this embodiment, a collection module (for example, a high-definition camera) is also installed on the transverse rods 1-4 of the support module, a waterproof canopy is installed on the top of the collection device, and a fill light is installed on the side. Preferably, in order to save costs, not every alarm system is provided with a collection module, but a collection module is provided for every other alarm system, for example, the first alarm system is provided with a collection module, the third alarm system is provided with a collection module, and the fifth alarm system is provided with a collection module.

[0046] In this embodiment, a projector is also installed on the transverse rods 1-4 of the support module, which is used to start all projectors within 2 km behind the incident point in the same direction after receiving the second start signal, projecting "Fault ahead, pay attention to avoid" in red font on the driving lane, and shut down the projector after receiving the stop signal. Preferably, a projector is set for every 5 warning systems; for example, the first warning system is set with a projector, the sixth warning system is set with a projector, and the eleventh warning system is set with a projector.

[0047] In this embodiment, a voice module is also installed on the transverse rods 1-4 of the support module, which is used to start all voice modules within 5 km in the same direction and rearward of the incident point after receiving the third start signal, and issue an alarm sound of "fault ahead, pay attention to avoid". Preferably, a voice module is set for every 5 warning systems; for example, the first warning system is set with a voice module, the sixth warning system is set with a voice module, and the eleventh warning system is set with a voice module.

[0048] In this embodiment, the control system is installed in the urban road command center, with a built-in urban road GIS electronic map, which displays the warning system of each section in real time and can autonomously send start and stop signals to the designated warning system, with the highest authority priority; the electronic map will display the coordinates of the fault signal point and display it as a red flashing dot. When the warning system is started, it will be displayed as a red flashing triangular dot.

[0049] In this embodiment, after the mobile robot 1-3 and the warning line storage module 1-8 receive the first start signal and longitude and latitude coordinates issued by the control system, they will move to the incident location specified by the remote control device, the warning line storage module 1-8 will move to 50 meters behind the temporary parking, and the mobile robot 1-3 will move to 3 meters behind the temporary parking. At the same time, the rotating bearing 1-6 drives the horizontal rod 1-4 to open, and then drives the supporting rod 1-5 to open, and the miniature speaker 1-10 sends an alarm message. The driver can choose to turn off the switch button 1-11. After turning off the switch button 1-11, the mobile robot 1-3 recycles the horizontal rod 1-4 and the supporting rod 1-5, and the warning line storage module 1-8 will move autonomously to the position of the mobile robot 1-3, and recycle the warning line 1-7 after the recovery rod is rotated by the rotating machine.

[0050] like Figure 5 As shown, based on the above-mentioned urban road temporary parking emergency handling device, the present invention also provides an urban road temporary parking emergency handling method, which specifically includes the following steps:

[0051] S1: The acquisition module collects road vehicle images in real time and sends them to the control system for storage;

[0052] In this embodiment, a high-definition picture of the monitoring range is collected every 3 seconds, and the picture is stored in a unified "JPEG" format and marked with the corresponding alarm system.

[0053] S2: The control system recognizes the image of the road vehicle and determines whether a temporary stop occurs; if so, it enters S3, if not, it continues to recognize.

[0054] S2-1: Use Python program to collect 10,000 pictures related to temporary parking on the road (including people getting off the car, double flashing, parking in the emergency lane, etc.) on the Internet to establish the first data set U;

[0055] S2-2: Use labelimg software to manually calibrate the temporary parking pictures in the data set U, calibrating "1" as temporary parking and "0" as normal, to obtain the second data set U1;

[0056] S2-3: Use the YOLOv5 library file in Python to perform recognition training on the second data set U1 to obtain the trained YOLOv5 model;

[0057] S2-4: Use the trained YOLOv5 model to recognize the real-time collected road vehicle images and output the recognition results. If the recognition result is "1", it means temporary parking, and if the recognition result is "0", it means normal.

[0058] S3: Sending the longitude and latitude coordinates of the temporarily parked vehicle and the first start signal to the mobile robot and the warning line storage module in the corresponding warning system.

[0059] In this embodiment, when a temporary stop occurs, the control system can identify the corresponding warning system number through the mark on the road vehicle image, and then obtain the latitude and longitude coordinates of the temporarily parked vehicle through the built-in urban road GIS electronic map.

[0060] In this embodiment, a second start signal is also sent to all projectors within 2 km behind the corresponding warning system in the same direction, and red words "Fault ahead, avoid" are projected on the driving lane. After receiving a stop signal, the projector is turned off.

[0061] In this embodiment, a third start signal is also sent to all voice modules within 5 km in the same direction and rearward of the corresponding warning system, and an alarm sound of "fault ahead, avoid it" is issued.

[0062] The advantage of this is that it can let vehicles behind in the same direction know that an accident has occurred ahead and that they need to slow down to avoid collisions and improve driving safety.

[0063] S4: Figure 6 As shown, after the mobile robot moves to the first distance (3 meters) behind the temporarily parked vehicle, the horizontal rod and the supporting rod are opened to play a fixed support role; then the warning line storage module moves to the second distance (50 meters) behind the temporarily parked vehicle, so that the warning lines 1-7 are pulled out to form a warning area behind the temporarily parked vehicle.

[0064] In this embodiment, after the rotary bearing 1-6 drives the horizontal rod 1-4 to open, it drives the supporting rod 1-5 to open, and the micro-speaker 1-10 sends out an alarm message.

[0065] The driver can independently choose to turn off the switch button 1-11. After turning off the switch button 1-11, the mobile robot 1-3 will recycle the horizontal rod 1-4 and the supporting rod 1-5; the warning line storage module 1-8 will autonomously move to the position of the mobile robot 1-3, and recycle the warning line 1-7 after the recovery rod is rotated by the rotating machine.

[0066] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
