And inquiring the rated load corresponding to the license plate number in a vehicle database judging module according to the license plate information. In addition, whether the automobile is a small automobile, a medium automobile or a large automobile can be analyzed according to the automobile type information. Since different types of vehicles have different rated load ranges, the rated load of the vehicle can be acquired according to the correspondence between the acquired vehicle type information and the rated load ranges.
The vehicle database judging module makes overload judgment according to the acquired rated load and axle load information of the vehicle, and then the controller receives a judging signal of the vehicle database and sends a judging result to the variable information prompt board in the identification and warning module 3.
When the vehicle database judges that the vehicle is overloaded, the variable information prompt board displays that 'the vehicle with the license plate number of XXXXXX is seriously overloaded, and please turn right to drive away from unloading'; meanwhile, the roadside alarm 6 gives an alarm to prompt the driver to turn right at the intersection in front to drive away from the unloading detour.
And when the vehicle database judges that the vehicle is not overloaded, the variable information prompt board displays that the vehicle with the license plate number XXXX is not overloaded and please run normally.
If the driver does not reckon, the driver can warn to continue driving forwards, then a mandatory measure must be taken to prevent the overloaded vehicle from driving into the bridge, the overloaded vehicle passes through one deceleration strip and reaches the second detection module 2, and the second pressure sensor converts the axle load of the vehicle to be monitored, which acts on the second pressure sensor, into an electric signal again and sends the electric signal to the controller. After the controller receives the electric signal sent by the second pressure sensor, the lifting type separation column 4 is started, so that the lifting type separation column rises to block the vehicle from passing, meanwhile, the roadside alarm 6 gives an alarm to force the large truck to unload, after the second pressure sensor detects that the axle load of the vehicle meets the specified requirements, the controller regulates and controls the separation column to automatically fall, the road traffic of the road section is recovered, the integral side-turning accident of the bridge caused by the overload vehicle entering the bridge can be effectively avoided, the structure is simple, the operation is convenient, and the practicability is strong.
