Directional loudspeaker control method and system applied to expressway

Abstract

The embodiment of the invention provides a directional loudspeaker control method and a system applied to expressway. The method comprises steps: analyzing environmental data in a tunnel to judge whether an accident occurs in the tunnel, and determining the accident occurrence position and the accident grade when the accident occurs, so that the available emergency exit in the tunnel is determined; then, according to the position of the available emergency exit, determining directional loudspeaker modules in the accident range and people flow information of the warning areas, and matching corresponding warning information for the directional loudspeaker module corresponding to each warning area; and finally, enabling the directional loudspeaker module to play the corresponding warning area to guide the personnel to go to the matched available emergency exit. By utilizing the characteristic of directional sound propagation of the directional loudspeaker module and combining the pedestrian flow condition in each warning area, the emergency exit is reasonably distributed, corresponding guide information is directionally propagated to personnel in the warning area, and orderly evacuation of the personnel is helped.

Description

Technical field [0001] This application relates to the field of highway safety management. Background technique [0002] With the rapid development of China's social economy, the road network extends to Chongshan Genling, the offshore deep water area, the total amount of highway tunnels continues to increase, and its safety operation management has become a key, difficult to point in the road management process. Once an accident occurred in the tunnel, such as fire, rear-end, explosion, pollutant leaks, etc., resulting in economic losses and property damage is often difficult to estimate, and if there is no time to evacuate the on-site person, it often causes secondary injuries. Generate more serious consequences. Since the highway tunnel is often located in a relatively remote mountain or offshore deep water area, after an accident, firefighters have changed their live time, and ordinary people who have not been professional training often cause the scene to evacuate due to pani...

AI Technical Summary

Problems solved by technology

Once an accident occurs in the tunnel, such as fire, rear-end collision, explosion, pollutant leakage, etc., the economic loss and property damage caused are often difficult to estimate, and if the on-site personnel are not evacuated in time after the accident, secondary injuries are often caused. have more serious consequences

Since expressway tunnels are often located in relatively remote mountainous areas or offshore deep water areas, firefighters often lag behind in reaching the scene after an accident, and ordinary people who have not received professional training during this period often have poor evacuation results due to panic.
