Problems solved by technology

The safety of the bridge due to the operation of overweight vehicles is mainly reflected in: serious damage to the bridge structure, ranging from interrupting traffic, to causing serious traffic accidents; increasing the load of the bridge, increasing the cost of bridge management and shortening The service life of the bridge, and even serious accidents such as bridge collapse and irreparable life and property
[0003] With the rapid development of science and technology, more and more bridges are now equipped with structural monitoring systems, and the rise of Internet of Vehicles technology can obtain real-time status information of overweight vehicles, which has played a role in the supervision of bridges and overweight vehicles to a certain extent. However, because these two types of data belong to different departments or enterprises, they have not exerted their maximum utilization value

Embodiment 1

[0030]In order to solve the problem of how to carry out early warning management and control of the safety risks existing in the driving process of overweight vehicles, improve driving safety, and avoid unnecessary loss of life and property; see figure 1 , the method mainly includes the following steps:

[0031] S101. Obtain the actual attributes and status information of the overweight vehicle to be tested before it crosses the bridge, including position, speed, acceleration, braking distance, total weight, load distribution, wheelbase, number of axles, number of wheels, and external dimensions.

[0032] Load distribution includes but not limited to linear distributed load, surface load, and body load. Wheelbase refers to the distance measured on the support surface between the tire symmetry planes of the left and right wheels on the same axis; The distance measured on the surface. The number of wheels refers to the total number of wheels of the vehicle. Dimensions can be...

Embodiment 2

[0065] On the basis of the above-mentioned embodiments, this embodiment provides an overweight vehicle driving state risk early warning system based on structure monitoring, which is used to implement the steps of the overweight vehicle driving state risk early warning method described in the above embodiment, please refer to figure 2, the system at least includes a roadside device 21 arranged on the road, a background service platform 22 communicating with the roadside device 21, a traffic management department monitoring center 23, a bridge operation management department monitoring center 24, and an overweight vehicle to be tested. The vehicle-mounted terminal 25 inside; Wherein

[0066] The background service platform 22 is used to receive the passing application filing of the overweight vehicle to be tested in advance, and store the filing attributes and status information, including position, speed, acceleration, braking distance, total weight, load distribution, wheel b...

Abstract

The invention provides an overweight vehicle driving state risk early warning method and system based on structure monitoring. The method carries out the risk dynamic recognition and early warning through the fusion analysis of the attribute and state information of an overweight vehicle and the bridge structure state monitoring data. Damage of overweight vehicles to a bridge structure, traffic interruption and blockage caused by the overweight vehicles and bridge collapse accidents can be effectively prevented or reduced to the maximum extent, and the driving safety of the overweight vehiclesis improved.

Description

technical field [0001] The invention relates to the technical field of traffic intelligent management and control, in particular to a method and system for early warning of risks in the driving state of overweight vehicles based on structure monitoring. Background technique [0002] Overweight vehicles refer to special vehicles that are larger than the bridge design load standard and the limit load announced by the road management department, and must take technical measures to pass the bridge, and are approved by the road management agency to drive on designated roads. Generally refers to the vehicle whose total vehicle weight or axle load and wheel weight exceed the design load when transporting inseparable overweight cargo (such as generator stators in large thermal power generation equipment, boiler steam drums, oxygen water tanks, etc.). The operation safety of the bridge due to the operation of overweight vehicles is mainly reflected in: serious damage to the bridge st...
