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
The present invention relates to fire alarm field, be specifically applied to evacuation emergency fireproof door or the fire-fighting life-saving channel of the public places such as large supermarket/shopping center, movie theatre, bar, hospital.
Background technology
Maximization, high stratification and complicated along with modern architecture, its fire fighting problem seems more and more important, people wish work, the living environment of safety and comfort, require to have a kind of automatic fire alarm system that is easy to management, can finds early fire accurate warning.The modern technologies such as integrated use computing machine, control, communication, figure demonstration, control function by the interlock to other fire fighting devicies, possess and self take precautions against natural calamities and extinguishing ability, can in modern architecture, play important safety guarantee effect.
The composition and working principle of automatic fire alarm system: automatic fire alarm system is mainly by trigger device (fire detector), fire alarm installation and the installation composition with other subsidiary functions, the physical quantitys such as smog, heat and optical radiation that it can produce burning at during Initial Stage of Fire, by fire detector, become electric signal, be transferred to fire alarm control unit, concurrently speak, light alarm signal, start fire-fighting link equipment.
Fire detector is topmost detecting element in automatic fire alarm system, the technical indicators such as the sensitivity of its work, reliability and stability directly affect the quality of whole system, common fire detector thoughts cigarette formula, temp sensing type, photosensitizing type, combined type and combustible gas probe etc., but because different temperature that substance combustion produces is different with smoke particle density, therefore by the variation of simple particle, photoelectricity and temperature, report to the police, its reaction velocity and accuracy are all not ideal.
Analog quantity fire detector essence is the sensor as detection, by Real-time Collection to on-site parameters be accurately and timely sent in detector for fire alarm system, in fire alarm control unit, the on-site parameters of sending here is carried out to analytic operation, realize " zero point " compensation, automatically remove the interference of environmental background, the memory function that utilizes fire detector itself to have, compares collection in worksite parameter and the detection parameter attribute curve that itself stores, and obtains warning message.Distributed intelligence formula detector is own with microprocessor, the acquisition parameter of site environment can be transformed into a real simulating signal or an equivalent numerical coding, carry out computing statistical estimation, then according to default relevant procedures, field data is in various degree converted into suitable actuation of an alarm index.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of corridor escape way voice broadcasting system and method for work thereof are provided, it can be when fire occurs, no matter in which kind of state, this cover system is audio alert at a terrific speed, prevents that obstruction personnel withdraw buildings because fear causes confusion under the emergency circumstance.
The technical solution adopted for the present invention to solve the technical problems is: corridor escape way voice broadcasting system, comprise voice broadcast main frame, voice broadcast main frame comprises for selecting the control circuit of working method, and this control circuit is connected to speech chip, and this speech chip passes through Single-chip Controlling; Described speech chip is inputted voice by microphone, and described speech chip is exported by voicefrequency circuit the voice of microphone input via loudspeaker;
