Interaction method and device for early warning of events in tunnel

Abstract

The invention provides an interaction method and device for early warning of events in a tunnel. The interaction method mainly comprises the steps that a terminal management platform sends the site range, obtained by an event detection system, of an accident in the tunnel to a front-end processor of the interaction device through a wireless communication network; the front-end processor starts a flash alarm and a moving device of the interaction equipment, the moving device drives the interaction equipment to move to an accident site, and in the moving process of the interaction equipment, the front-end processor controls the moving device to move to the accident site by analyzing real-time point cloud data of a laser radar of the interaction equipment; an administrator of the terminal management platform carries out conversation and traffic guidance with personnel in the tunnel through IP talkback broadcast of the interaction device. And when confirming that all the personnel evacuate from the lane and wait for rescue, the interaction equipment moves to the rear of the accident and circularly broadcasts early warning voice through IP talkback broadcasting, and early warning is carried out on the scene of the accident. And after the rescue personnel access, the interaction equipment stops early warning and recovers to the charging potential.

Description

technical field [0001] The present invention relates to the technical field of event early warning, and more specifically, to an interactive method and equipment for event early warning in a tunnel. Background technique [0002] With the implementation of the national transportation policy, China's transportation has entered a stage of rapid development, and the mileage of expressways, national and provincial highways, and urban roads has increased year by year. In order to improve the overall road traffic efficiency, facilities such as tunnels and overpasses appear frequently on urban roads and expressways, effectively shortening the distance between the two areas and reducing road congestion. Due to the particularity of the construction structure of the tunnel, the concealment is good. Once a traffic accident such as a car crash or fire occurs in the tunnel, the relevant personnel in the tunnel cannot find the escape route smoothly at the first time, and the vehicles that ...

AI Technical Summary

Problems solved by technology

Due to the particularity of the construction structure of the tunnel, the concealment is good. Once a traffic accident such as a car crash or fire occurs in the tunnel, the relevant personnel in the tunnel cannot find the escape route smoothly at the first time, and the vehicles that are about to enter the tunnel cannot be obtained in time. The real traffic conditions may easily lead to secondary accidents and cause greater casualties and property losses

[0003] With the continuous development of surveillance video and event perception technology, it is currently possible to provide necessary information for accident participants and other personnel by adding yellow flashing alarms and tweeters. There are mainly the following problems: 1. The content of the information release is relatively vague, and it is impossible to make directional calls for specific scenarios; 2. Relevant personnel cannot quickly find the emergency call facilities deployed in the tunnel due to tension and other reasons; 3. Vehicle noise and other interference related personnel Accurately obtain the emergency response plan; 4. It is difficult for follow-up vehicles to obtain the specific location of the accident in the tunnel in time, etc.
