the laser scanner 1 is used to detect whether the height of a vehicle adjacent to the height limit frame 6 exceeds the height limit of the height limit frame 6;
the camera 2 is used for acquiring images of the position of the height limiting frame 6 in real time and uploading the images to the central processing unit;
the controller 5 is used for controlling the sound post 4 to send out an alarm sound and the warning lamp 3 to flicker when the laser scanner 1 detects an ultrahigh vehicle, and uploading the alarm information of the detected ultrahigh vehicle to the central processing unit;
the central processing unit is used for: and judging whether collision occurs and the severity level of the collision according to the image acquired by the camera 2, and sending out an alarm of a corresponding level according to the severity level.
Specifically, the laser scanner 1 is fixed on a protective frame, and the path is horizontal to the road, vertical to the beam of the height limiting frame 6, opposite to the driving direction, and is emitted from the lower part of the beam of the protective frame. When the ultrahigh vehicle approaches the height limiting frame 6, the laser scanner 1 which horizontally emits on the height limiting frame 6 judges whether the vehicle is ultrahigh, and once the height exceeds the limited height, the sound column 4 gives an alarm and lights the warning lamp 3. The ultrahigh vehicle is recorded by the camera 2 and the ultrahigh vehicle data is transmitted to the central data processor. After the laser scanner 1 detects that the vehicle is ultrahigh every time, the vehicle information is recorded and uploaded to the central processing unit through the camera 2.
The central processor is specifically configured to classify and identify alarm information of the ultrahigh vehicle from the image uploaded by the camera 2, and determine whether a collision condition occurs and a severity level of the collision. The classification of the warning information of the ultrahigh vehicle includes the foreign matter blocking laser scanner 1 and the real ultrahigh vehicle blocking laser scanner 1.

Specifically, laser scanner 1 links to each other with the spirit level to guarantee that the angle is unanimous, in case spirit level angle slope, then judge 1 angular deviation of laser scanner, through angle adjustment module adjustment spirit level angle and laser scanner 1 angle simultaneously, guarantee laser scanner 1 horizontal emission, guarantee early warning precision.
In a specific embodiment, the adjusting module may include a stepping motor, and the level and the laser scanner 1 are mounted on the same supporting component, such as a supporting frame or a supporting plate, the supporting component is connected with a motor shaft of the stepping motor, and the stepping motor is used for driving the supporting component to rotate along the motor shaft and driving the level and the laser scanner 1 to rotate synchronously; the detection direction of the laser scanner 1 needs to be perpendicular to the axial direction of the motor shaft. The emergent angles of the level meter and the scanner are kept consistent, once the level meter is impacted or the angle is deviated due to overlong installation time, the level meter can automatically adjust the angle to return to the horizontal position again, and the emergent angles of the scanner are linked to ensure that laser emitted by the scanner keeps horizontal emergent forever.
In this embodiment, the controller 5 is further configured to estimate, according to the image of the vehicle to pass through the current bridge and culvert collected by the camera 2, a height of the vehicle to pass through the current bridge and culvert through an image recognition algorithm, and upload the estimated height to the central processing unit.
The central processing unit is further configured to:
and acquiring the limit height of the next bridge close to the current bridge according to the position of the current bridge, and if the height of the vehicle to pass through the bridge is smaller than the limit height of the height limiting frame 6 but larger than the height of the next bridge, controlling the sound column 4 to give out a prompt sound for prompting the limit height of the next bridge.
Specifically, the vehicle is crossed to camera 2 real-time recording to through controller 5 (can be for the inside data operation module of camera 2) rough judgement vehicle height of traveling, and with this data transmission to central processing system, central processing system acquires according to this bridge and culvert position and closes on the bridge and culvert restriction height, even the vehicle height is less than the height that current bridge and culvert was restricted, nevertheless be higher than and close on the height that bridge and culvert was restricted, can remind through sound column 4, inform the height that next bridge and culvert was restricted, make things convenient for the driver to handle in time, detour in advance.
In this embodiment, still include solar panel and power module, solar panel is connected with power module, and laser scanner 1, camera 2, warning light 3 and sound column 4 are connected with power module respectively.
