Description

Technical Field

[0001] This technical invention relates to a visual monitoring safety warning system suitable for battery vehicles in shield tunnels. The system combines deep learning and embedded systems, and has the characteristics of low cost, low energy consumption, long monitoring distance, high accuracy, and all-round monitoring without blind spots. The system relates to the field of shield construction technology, and in particular to a visual monitoring safety warning system suitable for battery vehicles in shield tunnels. Background Art

[0002] Every year, a large number of traffic accidents are caused by vehicle collisions in my country, especially some special vehicles. As an important long-distance tunnel transportation special vehicle in tunnel construction, shield tunnel battery vehicles undertake the work of transporting sand, stone, earthwork, materials, equipment, etc. However, in the actual working environment, due to the small curvature radius of the rails, poor light conditions, narrow space and other factors of the shield tunnel battery vehicle, the driver's driving vision is not wide, and the battery vehicle is large in size and mass, resulting in its inertia is also large. When there are pedestrians or debris in front of the battery vehicle, the battery vehicle is prone to extended braking distance or slipping. In the current visual monitoring safety warning market, the existing system cannot fully meet all the needs of shield construction battery vehicles. For example, the existing system monitors a short distance, and the vehicle cannot observe the work of personnel on the track in time during driving, or cannot receive relevant information, causing safety accidents. In addition, the existing system will trigger the warning system when it detects any obstacles, and some necessary facilities in the tunnel will also cause false alarms. Therefore, in order to prevent the occurrence of safety accidents to the greatest extent and ensure the safety of personnel and mechanical equipment during the construction process, in view of the current situation where information technology is widely used in shield engineering design, construction and management, there is an urgent need for a visual monitoring safety warning system suitable for shield tunnel electric vehicles. The system can be used to monitor the driving status of shield tunnel electric vehicles in real time and make relevant warnings for accidental and sudden situations. Summary of the invention
