Description

FIRE DETECTION SYSTEM

The present invention relates to a fire detection system, and more particularly, to a fire detection system, which is installed in an arbitrary place in a building, detects a rise in temperature and smoke concentration in a stepwise manner at the time of a fire and automatically transmits a signal to the 119 control center, In addition, fire control system that can prevent large-scale fire by transmitting fire occurrence information including fire signal, fire occurrence address, GPS position information, phone number information and camera screen to 119 control center and set user terminal .

Generally, a fire detector is installed on the ceiling to detect the occurrence of a fire in order to prevent a great damage to a fire that may occur unexpectedly in various buildings such as business, residence, and the like.

As a detector for detecting a fire and outputting an alarm signal to a receiver to perform a fire alarm, there is generally known a smoke detector for detecting smoke caused by a fire and a heat detector for detecting heat (temperature) caused by a fire. A hybrid type sensor that applies a gas sensor that detects the gas concentration of CO or the like to the same sensor has also been disclosed.

However, the conventional fire detector has disadvantages that it is difficult to respond quickly and appropriately to various fire situations such as a smoldering fire or an ignition fire only by the detection information such as the temperature or the smoke concentration.

In other words, the conventional fire detector is a method in which an already widely diffused flame and smoke resulting therefrom are made to sound an alarm. Such an alarm system has already spread to some extent, causing damage to human life due to smoke inhalation, It is difficult to effectively prevent the phenomenon.

In addition, the conventional automatic reporting system recognizes a fire even when heat or smoke is generated in a non-fire situation, thereby causing unnecessary 119 fire departments to be dispatched, thereby causing a serious problem that can not prevent a more urgent fire or accident there was.

Referring to FIG. 5, a fire sensor 100 according to an embodiment of the present invention can detect heat or smoke using a temperature sensor, a smoke sensor, or the like (S100). If the detected temperature of the temperature sensor reaches 80 占 폚 or smoke of a predetermined concentration is detected (S110) through the control unit 16 of the fire detector 10, the first fire warning signal is transmitted to the 119 control center 100 and the user terminal 200 (S120).

Thereafter, when the detected temperature of the temperature sensor rises above 80 ° C for more than 20 seconds (S130) or when the smoke concentration rises above the first measured smoke concentration (S140), a second fire warning signal is sent to the control center 100 To the user terminal 200 (S150). If the temperature or smoke concentration does not rise after 20 seconds, the primary warning signal will remain, and if the temperature sensor falls below 80 ° C or a certain set smoke concentration, the primary warning signal will also be canceled, Or temperature sensing (S140, S110).

If the temperature rises continuously or the smoke concentration becomes higher after 20 seconds (S160) after the secondary warning signal is transmitted (S170), the 119 control center 100 and the user terminal 200 provide a tertiary warning signal (S180).

Accordingly, when the set time and the set temperature are exceeded, the warning signal is sequentially sent to the control center 100 and the user terminal 200, thereby functioning as a filter to prevent malfunctions in the case of non-fire And it is possible to prevent a large fire by observing the warning address more carefully.

In the present embodiment, the temperature is 80 ° C and the time is 20 seconds. However, it is to be understood that the present invention is easily understood, and it can be variously modified in some cases.
