Corridor safety channel voice broadcast system and working method thereof

Abstract

The invention discloses a corridor safety channel voice broadcast system and a working method thereof. When a fire starts, the system can rapidly give a voice alarm whatever the state is, so as to avoid that disorder caused by panic prevents personnel from evacuating a building under an emergency state. The corridor safety channel voice broadcast system provided by the invention comprises a voice broadcast host. The voice broadcast host comprises a control circuit which is used for working mode selection. The control circuit is connected with a voice chip. The voice chip is controlled by a single chip microcomputer. The voice chip input voice through a microphone. The voice chip outputs the voice input by the microphone through an audio circuit and a loudspeaker. The voice broadcast host is connected an emergency light, an emergency power supply and a sensor. The sensor is a fire detector. The sensor is connected with a fire alarm device. The voice broadcast host, the emergency light, the emergency power supply and the sensor are powered by an external power supply, wherein the emergency light, the emergency power supply and the sensor are connected with the voice broadcast host.

Description

technical field [0001] The invention relates to the field of fire alarm, and is specifically applied to evacuation emergency fire doors or fire escape passages in public places such as large supermarkets / shopping centers, cinemas, bars, and hospitals. Background technique [0002] With the large-scale, high-rise and complex modern buildings, its fire protection problem is becoming more and more important. People hope to have a safe and comfortable working and living environment, and require a fire protection system that is easy to manage, can detect fires early and give accurate alarms. Automatic fire alarm system. Comprehensive use of modern technologies such as computer, control, communication, and graphic display, through the linkage control function of other fire-fighting facilities, has its own disaster prevention and fire-extinguishing capabilities, and can play an important role in safety guarantees in modern buildings. [0003] The composition and working principle ...

AI Technical Summary

Problems solved by technology

[0004] The fire detector is the most important detection element in the automatic fire alarm system. Its working sensitivity, reliability and stability and other technical indicators directly affect the quality of the whole system. Common fire detectors include smoke-sensing and temperature-sensing , photosensitive, composite and combustible gas detectors, etc., but because the temperature and density of smoke particles produced by different substances are different, so relying on simple particle, photoelectric and temperature changes to alarm, its response speed and accuracy are not good. too ideal
