A directional tweeter control method and system applied to highways

Abstract

The directional tweeter control method and system applied to highways provided by the embodiments of the present invention can determine whether an accident has occurred in the tunnel by analyzing the environmental data in the tunnel, and determine the accident location and accident level when the accident occurs, so as to determine The available safety exits in the tunnel, and then determine the directional tweeter module within the accident range and the traffic information of the warning area according to the position of the available safety exit, and match the corresponding warning information for the directional tweeter module corresponding to each warning area, Finally, the directional tweeter module plays to the corresponding warning area to guide the personnel to the matching available safety exit. This application utilizes the characteristics of directional transmission of sound from the directional tweeter module, combined with the flow of people in each warning area, rationally allocates safety exits, and disseminates corresponding guidance information to people in the warning area to help people evacuate in an orderly manner.

Description

technical field [0001] The present application relates to the field of expressway safety management, and in particular, relates to a directional tweeter control method and system applied to expressways. Background technique [0002] With the rapid development of my country's social economy, the highway network extends to high mountains and offshore deep water areas, and the total number and construction scale of highway tunnels continue to increase. The issue of safe operation and management has become a key and difficult link in the process of highway management and maintenance. 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 mounta...

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.
