Specifically, the vehicle superelevation detection system includes a laser transmitter and a laser receiver both connected to the processor.

Specifically, the weight detection system includes at least 4 pressure sensors.

Specifically, an LED display is also connected to the output end of the processor.

Specifically, the intercepting system includes a motor connected to the processor, and an intercepting pole connected to the motor and driven by the motor to intercept overheight or overweight vehicles.

Specifically, the image acquisition system includes multiple cameras that are activated or shut down under the control of the processor, and a memory card connected to the cameras and dedicated to the image acquisition system.

Specifically, the processor is an ARM processor.

Compared with the prior art, the utility model has the following beneficial effects:

The system of the utility model can accurately detect the weight and height of vehicles passing through the bridge, and intercept superhigh and overweight vehicles, prevent them from passing on the bridge, and maintain bridge safety and driving safety. At the same time, this system is equipped with two relief methods, one is the image acquisition system, which includes a camera and a memory card. If an emergency occurs at the monitoring site, it can be recorded in time and transmitted to the PC through the processor, which is convenient for relevant personnel to view And take corresponding measures; the other is to set up a license plate recognition all-in-one machine, which can effectively detect the license plate of the vehicle. It is convenient for relevant staff to intercept in time. This system can automatically detect, warn, intercept and track super-height and overweight vehicles. It has complete functions and is suitable for various bridges.

detailed description

The utility model will be further described below in conjunction with the description of the drawings and the embodiments, and the mode of the utility model includes but not limited to the following embodiments.

This embodiment provides an overweight and overheight detection and control system for bridge passing vehicles with simple structure and complete functions. The system can automatically detect bridges, warn and intercept overheight and overweight vehicles.

The overweight and overheight detection and control system for passing vehicles on bridges includes an ARM processor, a weight detection system for detecting the weight of passing vehicles connected to the input end of the ARM processor, a DC power supply for providing power to the entire system, and A vehicle overheight detection system for detecting vehicle height, an image acquisition system for monitoring image information, a license plate recognition all-in-one machine for identifying license plates, and a vehicle overheight or overweight warning system respectively connected to the output of the ARM processor. Sound and light alarm, interception system for intercepting super-high or overweight vehicles; the ARM processor is also wirelessly connected with the PC. Meanwhile, the ARM processing is also connected with a memory for storing detected information.

The output end of the ARM processing is also connected with an LED display, which is used to display information such as the height limit and weight limit of the bridge, and the height and weight of the detected vehicle, so that the driver can see it at a glance.

The vehicle superelevation detection system includes a laser transmitter and a laser receiver connected to the ARM processor and arranged on both sides of the road ahead of the bridge. The height of the laser transmitter window is equal to the height limit of the bridge. If it is received by the laser receiver, the vehicle can pass normally. If the laser receiver does not receive the emitted laser beam, the ARM processor will transmit the signal to the sound and light alarm and the interception system. The interception system is used to intercept the passage of super-high vehicles , the sound and light alarm is used to remind the driver of the vehicle that the vehicle is too high.

The weight detection system includes pressure sensors arranged on the road in front of the bridge and distributed in an array. The system can accurately detect the weight of passing vehicles and transmit the detected information to the ARM processor. If the vehicle is super high, the ARM processing After being processed by the sensor, it is sent to the sound and light alarm and the interception system. The interception system is used to intercept the passage of overweight vehicles, and the sound and light alarm is used to remind the driver of the vehicle that the vehicle is overweight.

The interception system includes an interception rod, and a motor connected with the interception rod for controlling the interception rod. Under normal conditions, the interceptor bar is in a vertical state, and when the ARM processor sends out an interception command, the motor controls the interceptor bar to rotate to a horizontal position to prevent overweight and ultra-high vehicles from passing.

Because some drivers of super-high and overweight vehicles forcibly pass the bridge because of emergency or because they don’t care about the instructions, in order to avoid this situation, this system is also equipped with a license plate recognition machine connected to the ARM input terminal, even if the super-high and overweight vehicles Forcibly crossing the bridge and escaping can also be quickly found through the license plate, which adds protection to the safety of the bridge. To prevent emergencies on site, in order to deal with them in a timely and effective manner, the system has an image acquisition system, which includes a camera and a dedicated memory card for the image acquisition system. The sensor is transmitted to the remote control center in time, so that the relevant personnel can understand the specific situation on the spot and take corresponding measures. On the other hand, the detected information can also be stored to facilitate the relevant personnel to retrieve information.

The above-mentioned embodiment is only one of the preferred embodiments of the present utility model, and should not be used to limit the protection scope of the present utility model, but any modification or embellishment without substantive meaning made on the main design idea and spirit of the present utility model, If the technical problems it solves are still consistent with the utility model, they should all be included in the protection scope of the utility model.
