Embodiment Construction

[0016] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0017] The fire alarm system includes a CO detection module, a smoke detection module, an infrared detection module, a controller module and a voice broadcast module; the output end of the CO detection module is connected to the controller module; the output end of the smoke detection module is connected to the controller The modules are connected; the output terminal of the infrared detection module is connected with the controller module; the control terminal of the voice broadcast module is connected with the controller module.

[0018] The combustion at the fire scene is mainly smoke and gas, and the gas mainly includes CO, that is, carbon monoxide. By detecting the smoke and CO at the fire scene, it can effectively judge whether a fire has occurred. CO poses a fatal threat to the trapped people. CO is inhaled into the lu...

Abstract

The invention discloses a fire alarm system; a CO detection module is arranged to detect CO content of a detection site; a smoke detection module is arranged to detect smoke of the site; an infrared detection module is arranged to detect whether human beings present on the site or not; the above detection signals are input to a controller module; a controller judges whether a fire occurs or not according to the CO content and the smoke quantity, and fire judging accuracy is improved; if a fire occurs and no one is present on the site, a speech broadcasting module is activated to give an alarm to remind people of taking corresponding measures; if there are human beings present on the site, the speech broadcasting module is activated to give an alarm and remind the personnel on the site of escape routes and modes, so that the personnel may be evacuated orderly to avoid chaos and loss; a flame detection module is also arranged to detect a flame on the site, a flame signal is input to the controller module so that the controller module may judge whether there is fire a or not more accurately, and the fire judging accuracy of the fire alarm system is improved.

Description

technical field [0001] The invention relates to a fire detection system for residences, factories and other occasions, in particular to a fire alarm system. Background technique [0002] Fire is a burning out of control in time or space, which will endanger public safety and social development. In shopping malls, residential areas, factories and other occasions, once a fire occurs, the loss of life and property safety will be very large. This requires that the escape routes in each occasion have no obstacles and can be used normally. It is also necessary for the trapped personnel to have fire protection knowledge and good psychological quality. , Do not act blindly, choose the correct way of escape, but also need the relevant person in charge, firefighters, etc. to take timely measures according to the dangerous situation to minimize the loss of life and property. [0003] People have developed a fire alarm system according to the needs, trying to detect a fire, and report ...
