[0019] Example 1, please refer to Figure 1-5 , an embodiment of the present invention provides a road warning system, comprising: Control module 1 adopts a dedicated integrated control board, which includes functions such as LED display and sign driver, 4G network communication, LoRa linkage control (wireless communication), radar docking, voice broadcast and flashing light control.

[0020] The communication module is used for monitoring and managing the front-end equipment and uploading the checkpoint data and the pictures of passing vehicles. In the present embodiment, the communication module may be a 4G communication module. Considering that the road warning system is mainly installed in relatively remote locations such as rural roads, urban-rural fringe areas, and mountain roads, and it is relatively difficult to transmit signals using optical fiber, the system has a built-in 4G communication system. Through the 4G network, the front-end equipment can be monitored and managed, and the checkpoint data and the pictures of passing vehicles can be uploaded in real time; the data can also be temporarily stored in the front-end equipment and called and downloaded as needed. The front-end monitoring can be browsed in real time, and the historical monitoring video of the front-end can be checked and downloaded at any time.

[0021] Detection module 2 is used to detect information about oncoming vehicles or pedestrians. In this embodiment, detection module 2 is specifically a vehicle detector, which uses millimeter wave and multi-target detection radar to conduct real-time monitoring of various types of motor vehicles and non-motor vehicles traveling at a speed exceeding 20 km / h on the main road. The detection distance can be as long as 100 to 150 meters. It can also conduct real-time detection of pedestrians and non-motor vehicles on branch roads, with a detection distance of up to 50 meters.

[0022] Camera 3 is used to capture pedestrians or vehicles.

[0023] The warning module 4 is used to remind vehicles and pedestrians to pay attention to traffic safety. The warning module 4 includes a warning light 401, a display screen 402 and a speaker 403. The warning light 401 can be a red and blue flashing warning light, the display screen 402 can be a high-brightness outdoor LED display screen or sign, and the speaker 403 can be a directional tweeter. It can provide warnings in multiple ways such as display, sound, and light to remind drivers to be cautious when passing other vehicles. When the system predicts that vehicles passing on the road may cause traffic safety risks to other passers-by and vehicles, the system will use the above-mentioned warning light 401 flashing and display screen 402 strobing to remind vehicles and personnel passing around the road to pay attention to traffic safety; at the same time, only when the system detects that there are pedestrians or non-motorized vehicles on the branch road that need to pass the intersection, will it use the speaker 403 to give a voice safety reminder, thereby minimizing the impact of the voice broadcast function on the lives of surrounding residents.

[0024] The power supply module 7 is used to supply power to the entire system, which can be specifically solar powered, including a solar panel installed on the top of the rain shield 12 and a lead-acid battery arranged inside the support module 10. The solar panel absorbs solar energy to charge the lead-acid battery, and the lead-acid battery then supplies power to the entire system; further, the installation section where the mains power supply conditions permit can be directly powered by mains power.

[0025] The fault self-diagnosis module 8 is used to detect whether the power supply module 7, the control module 1 and the detection module 2 have any faults. Once the power supply module 7, the control module 1 and the detection module 2 have any faults, an alarm message will be sent to the background application module 9 in real time.

[0026] The background application module 9 is used to receive the passing vehicle data and information sent by the control module 1. The system records and analyzes the vehicle traffic conditions at the intersection where the system is located, and determines the traffic status and traffic events.

[0027] The road warning system also includes an overspeed alarm capture module 6. The detection module 2 detects the real-time speed of the oncoming vehicle, and immediately alarms when it exceeds the set threshold, and links the high-definition camera 3 to capture real-time photos to the background application module 9.

[0028] The road warning system also includes a collision alarm capture module 5, which is used to issue an alarm within seconds when a collision occurs, and link the camera 3 to capture real-time data to the back-end application module 9.

[0029] The support module 10 can be specifically a rectangular sheet metal box, the control module 1, the communication module and the collision alarm capture module 5 are installed inside the support module 10, the warning module 4 is installed on the front end surface of the support module 10, the detection module 2 and the camera 3 are both installed on the top of the support module 10, and the top of the support module 10 is installed with a rain shield 12 through a bracket 11, the detection module 2 and the camera 3 are both located below the rain shield 12, and a storage cavity 1001 is provided at the top of the support module 10, and an opening 1002 for accommodating the detection module 2 and the camera 3 is provided through the top of the storage cavity 1001, and a sealing cover 1003 is detachably installed on the back of the storage cavity 1001, which is convenient for later disassembly and maintenance, and a support plate 18 for shielding the opening 1002 is horizontally movably provided at the top of the storage cavity 1001, and the size of the support plate 18 is The size of the storage chamber 1001 is larger than the size of the opening 1002. A linear drive member 17 is provided inside the storage chamber 1001 for fixing the support plate 18 below the opening 1002. The linear drive member 17 can be specifically an electric push rod. A positioning hole 1802 adapted to the output end of the linear drive member 17 is provided on one side of the support plate 18. When the output end of the linear drive member 17 is inserted into the positioning hole 1802, the support plate 18 is fixed to the bottom end of the opening 1002 to provide support for the detection module 2 and the camera 3. First reset mechanisms 13 for pushing the support plate 18 to separate from the opening 1002 are provided on both sides of the storage chamber 1001. A baffle 14 is fixed on the top of the detection module 2 and the camera 3, and a second reset mechanism 15 for pushing the two to be stored in the storage chamber 1001 and a locking mechanism 16 for fixing are provided on the top of the baffle 14. The size of the baffle 14 is larger than the size of the opening 1002.

[0030] Reference Figure 4 The first reset mechanism 13 includes a first guide rod 1301 horizontally fixed inside the storage cavity 1001, and a slider 1801 slidably connected to the first guide rod 1301 is provided on the side of the support plate 18. A first spring 1302 is sleeved on the first guide rod 1301 to push the slider 1801 to move to the side away from the opening 1002. The two first reset mechanisms 13 are respectively located on both sides of the support plate 18 to avoid affecting the up and down movement of the detection module 2 and the camera 3. In the normal state, the first spring 1302 is in a compressed state. When the linear drive member 17 is separated from the positioning hole 1802, the first spring 1302 can quickly push the support plate 18 away to the side of the opening 1002.

[0031] Reference Figure 4The second reset mechanism 15 includes two second guide rods 1501 vertically fixed to the top of the baffle 14 and a second spring 1502 sleeved on the second guide rods 1501. A through hole for accommodating the second guide rods 1501 to slide up and down is provided on the bracket 11 directly above the second guide rods 1501. After the two second guide rods 1501 pass through the through hole, they are connected and fixed by the limit plate 1503. The top of the second spring 1502 abuts against the bracket 11, and the bottom of the second spring 1502 abuts against the baffle 14. Under normal conditions, the second spring 1502 is in a compressed state, so that the bottom ends of the detection module 2 and the camera 3 abut against the top of the support plate 18. When the support plate 18 moves to one side, the second spring 1502 can quickly push the detection module 2 and the camera 3 into the storage cavity 1001 to play a protective role.

[0032] Reference Figure 4 The locking mechanism 16 includes a connecting rod 1601 vertically fixed to the bottom end of the limiting plate 1503 and an elastic buckle 1602 fixed to the bottom end of the connecting rod 1601. The bracket 11 is penetrated with a plug hole 1101 for accommodating the elastic buckle 1602 to pass downward. The elastic buckle 1602 passes downward through the plug hole 1101 to achieve clamping and fixing. The elastic buckle 1602 is specifically a V-shaped spring sheet structure. After the elastic buckle 1602 passes downward through the plug hole 1101, the top opening opens and presses against the bottom end of the bracket 11 to achieve locking, so as to prevent the detection module 2 and the camera 3 inside the storage cavity 1001 from being thrown out again when a collision occurs, and the protection is better.

[0033] The specific application scenarios of this road warning system include branch road warning, intersection without traffic lights, T-junction warning, factory / residential entrance and exit warning, ramp merging, highway slope warning and curve warning. It is generally used in pairs, one for detecting vehicles or pedestrians, and the other for warning vehicles or pedestrians in the oncoming direction.

[0034] Working principle: The road warning system relies on the detection module 2 to scan large, medium and small motor vehicles and possible non-motor vehicles, and conducts long-distance detection of vehicles, analyzes the direction, distance and speed of the approaching vehicles, and when there is a possibility of causing harm to pedestrians on the branch road, the system will project the detected approaching vehicle information to the display screen 402 set in the direction of the branch road, and remind pedestrians or drivers to pay attention to vehicle avoidance and safe passage by means of a horn 403 and flashing red and blue warning lights 401; During normal operation, the support plate 18 is pushed to move to the bottom of the opening 1002, the linear drive member 17 is extended, and the output end is inserted into the positioning hole 1802 to limit the support plate 18. At this time, the slider 1801 compresses the first spring 1302, and the bottom ends of the detection module 2 and the camera 3 abut against the top of the support plate 18. When the support module 10 is hit, the linear drive member 17 contracts, and the first spring 1302 is reset to push the support plate 18 to the side of the opening 1002. The second spring 1502 also pushes the baffle 14 to move downward, and the detection module 2 and the camera 3 at the bottom of the baffle 14 pass through the opening 1002 and are collected into the storage cavity 1001. At the same time, the elastic buckle 1602 passes downward through the plug hole 1101 and then opens its top to abut against the outer wall of the bracket 11 to lock the baffle 14. At this time, the baffle 14 overlaps the top of the opening 1002 to prevent the detection module 2 and the camera 3 from being damaged by external force.
