Problems solved by technology
However, the weight detection at the station only detects the vehicle weight of the vehicle on the expressway, which is one-time, and cannot detect the vehicle on other road sections, and cannot track in real time, so it cannot effectively solve the problem caused by the overweight of the vehicle. various problems

Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.
[0036] see Figure 1-6 , a method of using laser reflection to detect bridge loads is characterized in that: a laser emitting device 2, a camera 3, a laser receiving device 4, and a display screen 6 are all connected to a controller 5, and a solar power generation panel 7, a wind power generation device 8 and The battery is connected to form a power supply system. The laser emitter in the laser emitting device 2 can emit argon flu...

The invention relates to a method for detecting bridge loads by using laser reflection, and belongs to the field of traffic automation and bridge safety. An argon fluoride ultraviolet laser beam can be emitted by a laser transmitter in a laser transmitting device, so that diffuse reflection occurs on a road surface, light in the process of diffuse reflection is received by a transmission screen onthe surface of a laser receiving device, and the light variation of the argon fluoride ultraviolet laser beam used for detecting the road surface is sensed by a solar-blind light sensitive resistor arranged in the laser receiving device. When a vehicle passes through a road section, the plate number of the driving vehicle is photographed by a camera arranged on the same side of the laser transmitting device, deformation of the road surface is generated due to the entering of different vehicles at the moment to cause the changing of the light intensity when the diffuse reflection of the argonfluoride ultraviolet laser beam on the road surface occurs to further change the resistance of the solar-blind light sensitive resistor, the variation resistance of the solar-blind light sensitive resistor is transmitted to a controller to compute the weight of the vehicle currently passing through the road surface, and the weight is displayed on a display screen together with matching plate number information collected by the camera.
Description
technical field [0001] The invention relates to a method for detecting bridge loads by using laser reflection, which belongs to the field of traffic management system optimization. Background technique [0002] Article 48 of the "Road Traffic Safety Law of the People's Republic of China" stipulates that "motor vehicles shall meet the approved load quality, and overloading is strictly prohibited; the length, width and height of the load shall not violate the loading requirements, and the load shall not be spilled or scattered ", Article 49 stipulates that "the number of people on a motor vehicle shall not exceed the approved number, and passenger motor vehicles shall not carry goods in violation of regulations." In recent years, the overweight phenomenon of road transport vehicles in our country is very common. In some serious areas, almost all freight vehicles have different degrees of overweight transportation behavior. Some overweight ratios are very high. A car is even mo...
