AI Technical Summary

Technical Problem

The existing tunnel fire emergency communication system is not reliable enough in complex environments, with communication delays or interruptions, single on-site warning methods, and limited fire telephone functions, making it difficult to achieve real-time and effective emergency response and personnel evacuation.

Method used

The optical fiber communication network combines manual fire alarms with explosion-proof IP phones. Alarm information is transmitted through optical modems and switches to achieve linkage between manual fire alarms and fire sound and light alarms. Intercommunication between extensions and continuous alarms are supported, and the equipment has an explosion-proof design.

Benefits of technology

Ensure real-time transmission of alarm information, generate high-intensity sound and light signals, support intercommunication between extensions, adapt to harsh environments, reduce the risk of information omissions and secondary damage, and improve emergency response efficiency.

Abstract

The invention discloses a manual fire alarm and broadcast scheduling system and method for tunnel operation. The system comprises a manual alarm subsystem and a broadcast scheduling alarm subsystem. The manual alarm subsystem comprises a manual fire alarm and a fire-fighting audible and visual alarm; the broadcast scheduling subsystem comprises an explosion-proof IP telephone, a scheduling desk type host and an IP telephone server. The method comprises the steps that the manual alarm subsystem gives an alarm through a manual fire alarm fixed and preset in a tunnel, the manual fire alarm contacts with a dispatching desk type host, and the manual fire alarm triggers a fire-fighting audible and visual alarm to send out an audible and visual alarm signal to remind nearby people to evacuate at the same time; the broadcast scheduling subsystem displays alarm information through a scheduling desk type host, an IP telephone server contacts an explosion-proof IP telephone fixedly preset in a tunnel, and the explosion-proof IP telephone triggers a fire-fighting audible and visual alarm to send out an audible and visual alarm signal at the same time to remind people nearby to evacuate.
