Sound evacuation guiding system and guiding method in building fire

Abstract

The invention discloses a sound evacuation guiding system and guiding method in a building fire, and belongs to the technical field of building fire emergency evacuation. The guiding system comprises a plurality of sound production modules and an evacuation guiding controller. The sound production modules are connected with the evacuation guiding controller through audio data lines and a communication bus. The evacuation guiding controller is connected with a fire alarm controller through a communication bus. The evacuation guiding controller comprises a control unit, an audio signal processing unit, an audio power amplifying unit, a communication unit, a storage unit, a man-machine interaction unit and a power source circuit. The guiding method comprises the steps that the sound production modules are arranged at intervals along an evacuation exit, sound signals are stored in the storage unit of the evacuation guiding controller, when the fire breaks out, the control unit enables the sound production module which is arranged closest to an emergency exit inside the evacuation exit to firstly produce sound, then enables the next adjacent sound production module to produce sound, and enables all the sound production modules to produce sound in the mode, and the farther the sound production module is away from the safety exit, the later the sound production module produces the sound.

Description

technical field [0001] The invention belongs to the technical field of building fire emergency evacuation, in particular to a sound evacuation guiding system and guiding method in building fire. Background technique [0002] Crowded places often have large building space, many ignition sources, fast fire spread, and many combustible materials used. Once a fire occurs, it is very easy to cause heavy casualties and property losses. Therefore, rationally arranging safe evacuation routes and formulating emergency evacuation strategies are very important for quickly evacuating people to safe places in the event of a fire. [0003] The fire emergency lighting system mainly includes accident emergency lighting, evacuation exit signs and indicator lights, which are set up to guide trapped people to evacuate or launch fire fighting and rescue operations in the event of a fire. The national standard GB50016-2006 "Code for Fire Protection Design of Buildings" stipulates the requiremen...
