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 an increase in smoke concentration at a time of a fire, automatically transmits a signal to a 119 control center and a user terminal, It sends fire information including fire signal, fire occurrence address, GPS location information, telephone number, etc. to 119 control center and set user terminal, and installs a fan that operates as a motor in the fire detector, To a fire detection system capable of preventing malfunction of a fire detector by discharging heat and smoke contained in the fire detector.

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.

The temperature sensor 11 is a temperature sensor that operates when the temperature exceeds a predetermined temperature, and may include both a non-contact type and a contact type. The contact method is a method of measuring temperature by directly contacting a temperature sensor to a measurement object, and the non-contact method is a method of measuring heat radiated from a measurement object. For example, it may include a thermocouple, a metal-on-a-body, a thermistor, an IC temperature sensor, a magnetic temperature sensor, a thermopile, and a superconducting temperature sensor.

The smoke detection unit 12 may include both an ionization type sensor and a photoelectric type sensor as a sensor for detecting smoke. The ionization type is a method of detecting a fire by using the change of current when the smoke enters the sensing part, and when the photoelectric type of smoke is introduced into the sensing part, the current is constantly changed by the photoelectric element by the smoke, Method.

The fan 15 is operated by a fan for a predetermined time (for example, 3 to 5 seconds) when the smoke is detected by the smoke detection unit 12, so that the smoke penetrating into the smoke detection unit 12 can be released. When the smoke is detected again for a predetermined time (for example, 3 to 5 seconds) after the fan operates, the fan 15 can be continuously operated. The reason for this operation is to prevent an error that the smoke detector 10 continues to operate due to the smoke contained in the fire detector 10 even though the fire is suppressed.

The receiving unit receives a fire information signal such as a heat or smoke detection, a set address and a telephone number (or an IP address of a broadband communication network) From the communication unit (13) of the fire detector (10). The transmitting unit transmits the fire information signal received from the receiving unit 119 to the control center 100 and the user terminal 200. Accordingly, the fire occurrence information is displayed on the 119 control center screen 110, and a fire alarm signal can be transmitted to the set user terminal 200.

The 119 control center (100) is a 119th fire prevention center concept including both a regional and a comprehensive control center.

The user terminal 200 may be a mobile phone, a smart phone, a notebook computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a navigation device, a tablet computer, an e-book terminal, and the like.

In addition, a text message may be displayed on the user terminal when a fire is detected, such as a display screen of a 119 control center screen to be described later (see FIG. 4). [

Referring to FIG. 5, the fire sensor 10 according to the present invention can detect heat or smoke using a temperature sensor, a smoke sensor, or the like (S100). At the same time, when the heat or the heat is detected, the fan operates for a predetermined time (for example, 3 to 5 seconds), and the smoke contained in the fire detector 10 is released (S105). At the same time, a warning message is transmitted to the user terminal and the center 119 (S120).

After a predetermined time elapses, the heat and temperature are sensed again (S110). When the heat and temperature are sensed, the fan continues to operate (S130). If the heat and temperature are not sensed after a predetermined time elapses, (S140).

That is, when heat is sensed by the thermal sensor of the fire detection module, the fan 15 can operate until the temperature inside the fire detector falls down. At this time, the fan 15 detects the temperature And the like.

Therefore, it is possible to prevent a malfunction that may occur due to the smoke contained in the fire detector 10 and the residual heat, despite the fire being suppressed.

In the present embodiment, the time for the fan 15 to operate for a predetermined time is 3 to 5 seconds. However, it is to be understood that the present invention is not limited thereto, Do.

In addition, the fan 15 of the present invention can be operated in the clockwise direction and the counterclockwise direction in the rotating direction, which allows the user to select a method of discharging smoke or heat in the fire detector 10 to the outside or sucking it inward .
