Problems solved by technology

The overloaded and overloaded transportation of vehicles has caused huge losses to people's lives and properties. The main hazards are: (1) The overloaded and overloaded vehicles have seriously damaged the road infrastructure. (2) The vehicle is overloaded and overloaded, the load mass increases and the inertia increases, the braking distance increases, and the danger increases
If it is seriously overloaded, it will cause accidents such as tire blowout, sudden deviation, brake failure, rollover and other accidents due to excessive tire load and deformation; Accidents; (3) The driver's psychological burden and ideological pressure will often increase when driving an overloaded vehicle, which is prone to operating errors, which will affect driving safety and cause traffic accidents; (4) due to the overloaded vehicle cannot reach normal Driving at high speed and occupying the lane for a long time will directly affect the smooth flow of the road
[0003] my country's highways include expressways, first-class highways, second-class highways, third-class and fourth-class highways, and the situation of overloaded transport of large and medium-sized trucks is more serious in the passage of expressways, first-class highways and second-class roads; the traditional monitoring tools are A single camera shooting record or mobile monitoring platform tracking, but its monitoring effect is not ideal, and when the camera is shooting, the huge traffic flow greatly increases the workload of the camera, and has a large amount of monitoring data to increase the data of the traffic control department Difficulty of extraction and data analysis

Embodiment 1

[0025] like figure 1 and figure 2 As shown, this embodiment includes the following steps:

[0026] A When the moving vehicle touches the lower pressure plate, the lower pressure plate moves downward under force and contacts the pressure sensor;

[0027] The B pressure sensor transmits the detected pressure data to the controller, and the controller sends instructions to lens A, lens B, and lens C to take pictures of the license plates of passing vehicles respectively, so as to complete the collection of vehicle overload conditions;

[0028] C The lower pressure plate cooperates with the pressure spring to reduce the impact on the pressure sensor caused by the instantaneous stress generated when the vehicle is in contact with the lower pressure plate. When the pressure measured by the pressure sensor is in a different range, lens A, lens B and lens C are Take pictures of the license plate of the driving vehicle. For example, after the pressure sensor detects the load of a me...

Embodiment 2

[0034] like figure 1 As shown, on the basis of Embodiment 1, the present embodiment also includes a photoelectric switch 8, the photoelectric switch 8 is located on the road 9 and on both sides of the substrate 1, the photoelectric switch 8 is connected to the monitor 7, and according to the driving vehicle For the load range, the lens A4, the lens B5, and the lens C6 respectively take pictures of the license plate of the driving vehicle; when the moving truck approaches the substrate 1, the photoelectric switch 8 sends a signal to the monitor 7, and the monitor 7 starts to monitor the driving vehicle. Real-time monitoring video; when the truck passes the lower platen 2, the photoelectric switch 8 controls the monitor 7 to stop monitoring the running vehicle, so as to avoid the useless information in the monitor 7 from occupying more space for storage, and to facilitate the monitoring of illegal vehicles. Organize and collect.

Embodiment 3

[0036] like figure 2 As shown, in this embodiment, on the basis of Embodiment 1, the lens A4, the lens B5, and the lens C6 are all 2 million pixel cameras. During the driving process of the truck, the camera captures the license plate of the vehicle in an instant. The 2-megapixel camera can ensure that the license plate of the truck driving at high speed is clearly captured, so as to ensure that the traffic control department can obtain accurate data.

[0037] Preferably, the upper surface of the lower pressing plate 2 is arc-shaped. The arrangement of the arc-shaped surface can prevent the truck wheel from producing obvious bumps when it contacts the lower platen 2 , and reduce the impact on the detection accuracy of the pressure sensor 12 .

Abstract

The invention discloses a motor vehicle overloading determining method. The method includes the following steps: when a traveling vehicle is in contact with a lower pressing plate, the lower pressing plate is driven to move downward and is in contact with a pressure sensor. The pressure sensor transmits pressure data detected to a controller which commands a camera A, a camera B and a camera C to separately photograph the license plates of traveling vehicles which pass by so as to collect overloading of traveling vehicles. The lower pressing plate cooperates with a pressure spring, which can reduce impact on the pressure sensor imposed by transient pressure produced when the contact between a vehicle and the lower pressing plate occurs, and when the pressures measured by the pressure sensor are within different ranges, the camera A, the camera B and the camera C separately photographing the license plates of the traveling vehicle, recording the overloading of the vehicle, helps traffic management departments to punish the overloading accordingly, maximizes the protection of highways and relevant facilities, reduce overloading of vehicles, and keep roads safe and unimpeded.

Description

technical field [0001] The invention relates to a detection device, in particular to a method for judging overloading of a motor vehicle. Background technique [0002] Vehicle overloading means that the weight of the goods carried by the vehicle or the number of people exceeds the approved mass or number of people in the driving license; vehicle overloading means that the axle load quality, the total mass of the vehicle or the total size of the vehicle exceeds the limit stipulated by the state. Overloading of vehicles has caused great harm to safe driving or transportation, seriously endangered the life and property safety of the country and the people, and induced a large number of road traffic accidents. According to statistics, 70% of road traffic accidents are caused by over-limited and overloaded vehicles, and 50% of mass death and mass-injury accidents are directly related to over-limited and overloaded vehicles. The overloaded and overloaded transportation of vehicle...
