In addition, the present application forms a linear height detection structure using the first height detection unit, and referring to fig. 3, in order to prevent the vehicle speed from being too fast, the first height detection unit has low sensitivity, and thus the vehicle cannot be detected to be ultra-high, the present application also forms a cross-type height detection structure using the second height detection unit and the third height detection unit (at this time, the vehicle has entered the cross-type height detection structure), and as a backup detection structure, the accuracy of detection is improved.
From the above, when the controller of the present application determines that the current vehicle is an ultrahigh vehicle according to the height detection signals of the first height detection unit, the second height detection unit and the third height detection unit, the controller controls the vehicle information identification module to collect license plate information, vehicle owner information, vehicle ultrahigh information and the like of the ultrahigh vehicle, and displays the license plate information, the vehicle owner information, prompt information of "you are ultrahigh and please detour or please turn around" and the like by using the display module 6, so as to remind a driver of the current vehicle, and timely turn around or turn around to avoid the risk of collision with the portal frame 7 in front, thereby reducing the potential traffic safety hazard.
As a further alternative embodiment, the distance between the first upright 11 and the second upright 12 is a first preset distance;
the distance between the third upright post 21 and the fourth upright post 22 is a first preset distance.
Specifically, the distance between the first column 11 and the second column 12, and the distance between the third column 21 and the fourth column 22 are set to be the same distance, that is, both are set to be the first preset distance, which can be set according to actual conditions, when the road in front of the gantry 7 is relatively flat and the speed of the vehicles coming and going is relatively fast, the first preset distance can be set to be a longer distance, so as to ensure the accuracy of the height detection of the second height detection unit and the third height detection unit, otherwise, the first preset distance can be set to be a shorter distance.
Further as an optional implementation manner, the vehicle information recognition module comprises a license plate recognition camera.
Specifically, the license plate recognition camera is used for recognizing the license plate of an ultrahigh vehicle, an electronic police algorithm is built in the license plate recognition camera and used for recognizing information such as license plate information, vehicle information and vehicle owner name, the controller transmits the information such as the license plate information, the vehicle information and the vehicle owner name to the display module 6, the display module 6 is used for displaying the license plate information, the vehicle owner name and prompt information that a user is ultrahigh and please detour or turn around, and the like.
Further as an optional implementation manner, the vehicle information identification module further includes an intelligent traffic light supplement lamp.
Specifically, the intelligent traffic light supplement lamp is used for supplementing light when collecting information for the license plate recognition camera under the condition that light is insufficient such as night.
Further as optional implementation mode, the height limiting device for roads and bridges further comprises a warning lamp, and the input end of the warning lamp is connected with the output end of the controller.
Specifically, the warning lamp is used to visually indicate that an ultra-high vehicle has been ultra-high. When the controller detects that the current vehicle is ultrahigh, the warning lamp is controlled to flicker, and therefore the driver is prompted in the aspect of vision that the current vehicle is ultrahigh.
Further as an optional implementation manner, the height limiting device for the road and the bridge further comprises a voice prompt module, and an input end of the voice prompt module is connected with an output end of the controller.
Specifically, this application has still set up the voice prompt module for give out the prompt tone to super high vehicle.
