Building fire emergency alarming system

Abstract

The invention discloses a building fire emergency alarming system. A microcontroller is respectively connected with an infrared thermal imaging module, a CCD imaging module, a smoke sensor and a voice broadcasting module, wherein the smoke sensor can monitor a fire condition in the environment for 24 hours, in the case of a fire, fire alarming signals are transmitted to a remote monitoring terminal through wired and wireless modes, and a condition in which a wired communication line is broken in the case of the fire and alarming can not be carried out can be prevented; the CCD imaging is used for video detection in a normal condition; the infrared thermal imaging module is used for video detection when the fire happens at night or the CCD imaging picture is not distinct seriously due to large smoke, and the fire condition can be effectively observed. The system of the invention has wired and wireless image transmission modes, and thus, the phenomenon that the wired communication line is broken in the case of the fire and a fire video picture can not be transmitted can be prevented. A voice broadcasting function is provided, and a monitoring person can transmit voice signals to the microcontroller.

Description

technical field [0001] The invention belongs to the technical field of fire detection, and in particular relates to a building fire emergency alarm system. Background technique [0002] With the rapid development of social economy, safety accidents such as high-rise building fires and forest fires have become increasingly prominent and have received more and more attention. [0003] The traditional fire alarm method is to judge whether there is a fire through the smoke alarm or the temperature alarm. Although this can effectively judge the occurrence of the fire to a certain extent, it cannot effectively observe the fire situation at the fire scene, especially when the fire occurs At night (fire without lighting) or due to heavy smoke, traditional CCD video surveillance cannot play the role of observing the fire scene; moreover, when a fire occurs, it is very likely that the normal wired communication network has been damaged and the power supply is cut off , which seriousl...
