Bridge overload management device and method

Abstract

The invention provides a bridge overload management device and method. The device comprises a vehicle weight collection module, a weight calculation module and a traffic light control module. The vehicle weight collection module is used for obtaining vehicle weight information and vehicle number information from an installed weight collection device. The weight calculation module is used for obtaining a final weight value according to the vehicle weight information and the vehicle number information. The traffic light control module is used for comparing the final weight value with a preset weight threshold N1 and controlling a green light to turn into a red light to prohibit vehicles from passing if the final weight value is greater than or equal to the preset weight threshold N1. According to the invention, the total weight of vehicles on a bridge can be effectively controlled within the bearing range of a bridge body, and meanwhile, overloaded vehicles or suspected vehicles can be snapshot and monitored, and bridge collapse accidents caused by overweight vehicles can be prevented.

Description

technical field [0001] The invention mainly relates to the technical field of traffic management equipment, in particular to a bridge overload management device and method. Background technique [0002] In the prior art, bridges are the main traffic facilities for maintaining the smooth flow of urban expressways, especially in some cities close to large rivers, the safety and smoothness of bridges are the most critical parts for maintaining smooth urban traffic. [0003] However, the defect of the prior art is that no overweight vehicle detection and management device is set on each branch road leading to the bridge or the main road of the bridge, and only rely on weight limit warning signs to warn vehicles passing through the bridge. In order to reduce production costs and expand production profits, some transport companies often illegally load transport vehicles with overweight loads. Overweight transport vehicles not only crush the road surface of the bridge, but also cau...

Problems solved by technology

[0003] However, the defect of the prior art is that no overweight vehicle detection and management device is set on each branch road leading to the bridge or the main road of the bridge, and only rely on weight limit warning signs to warn vehicles passing the bridge

In order to reduce production costs and expand production profits, some transport companies often illegally load transport vehicles with overweight loads. Overweight transport vehicles not only crush the road surface of the bridge, but also cause frequent maintenance of the bridge road surface, causing traffic jams, and making the majority of office workers miserable. And it will bring great safety hazards, such as bridge collapse, overweight caused the steering wheel to be insensitive and hit the bridge body, etc.

[0004] The construction of the bridge is very difficult, and its cost is also very high. It usually requires billions of funds, and sometimes it takes four or five years to complete the construction. The bridge girder was hit by an overweight vehicle, and the bridge girder had to be replaced. The loss caused by a single girder was several million. The maintenance traffic was blocked for several months, and some people broke through the bridge and fell into the river. If the overweight vehicle lost control and hit The main or auxiliary cables of the bridge will be dangerous to the entire bridge
