Description

Technical Field

[0001] The utility model relates to the technical field of expressway early warning, and in particular to an expressway road facility safety perception early warning system. Background Art

[0002] For a long time, highway management departments have attached great importance to the safety of road equipment and facilities, but there are still weaknesses in management, which are mainly reflected in the following aspects:

[0003] 1. Manual inspections require the arrangement of vehicles, personnel and other departments to cooperate. The inspection time is relatively long, the efficiency is low, and a large amount of manpower, material and financial resources are wasted.

[0004] 2. Guardrails, height limit frames and other equipment cannot be discovered in time after a collision, especially in minor accidents. The vehicle can drive normally after the collision, causing the collision vehicle to drive away from the accident site. The damage can only be discovered during the next inspection, leaving safety hazards and the corresponding person responsible for the accident cannot be found, making it impossible to recover the losses and increasing daily maintenance costs.

[0005] 3. Accidents cannot be discovered in time, and drivers can only passively wait for rescue calls. They cannot proactively warn vehicles behind them in time, which can easily lead to secondary accidents. At the same time, rescue forces cannot be arranged to arrive at the scene in time, and the wounded cannot be handled and treated in time, leading to some irreversible consequences.

[0006] Therefore, it is necessary to build a road facility safety perception system on sections of highways prone to traffic accidents. The system can accurately locate and monitor in real time the location and time of collisions between facilities and equipment, and push the information to the highway management department as soon as possible. This will enable timely discovery, timely disposal, and timely repair, and avoid secondary injury accidents caused by damage to facilities and equipment. The safety system can also be used to monitor height limit frames under highway bridges, highway electromechanical facilities, etc. Utility Model Content
