Wireless fire alarm system and method

The present invention relates to a wireless fire alarm system and method, and more particularly, in the field of firefighting, unlike wired communication of automated material detection equipment including a detector transmitter repeater receiver, fire or any accident situation. First of all, it immediately detects the state of the temperature (heat) flame combustion product (smoke such as toxic gas) through the wireless sensor (A) that is recognized first, and then the fire detection signal of the wireless detector (A) and the button of the wired / wireless transmitter (D). Directly transmits signals or voice signals to other devices such as repeaters and receivers through wireless communication, while external detectors such as fire stations, etc. go through radio repeaters and radio receivers as starting points. It provides wireless fire alarm system to automatically connect and transmit to the public. Through this, 119 report and emergency dispatch of fire engine and ambulance are provided. The present invention relates to a wireless fire alarm system and method configured to respond quickly to various disaster safety accidents such as fire and gas explosion accidents.

In the disaster situation in the event of a re-occurrence or gas explosion, people who remain in the upper floors such as the first floor and the second floor in the Golden Time (approximately 1 to 15 minutes) may spread the toxic gas of the flame and fire by the wind. You must evacuate urgently before you lose your life.

In the field of firefighting, the automated material detection system detects fire temperature (heat) flames by a detector and receives the detected fire occurrence signal and voice from the detector to the receiver through a repeater and rings an emergency bell to report 119 within the Golden Time. And fire trucks and rescue teams are dispatched to reduce the damage caused by casualties and fires.

In related prior art 1, Patent Publication No. 10-2017-0065217 discloses a "complex fire detector and a fire monitoring system including the same".

1 is an internal configuration of a conventional composite fire detector.

`` Compound fire detector of the prior art 1 includes a temperature sensor for sensing a temperature and transmitting a temperature detection signal, a flame sensor for detecting a flame and transmitting a flame detection signal and a smoke sensor for detecting smoke and transmitting a smoke detection signal; A sensor unit 10; A control unit 30 for determining whether a fire has occurred by analyzing the detection signals transmitted by the sensors constituting the sensor unit 10; And a communication unit 40 for performing communication with the outside under the control of the controller. The complex fire detector 1 includes a sensor unit 10, an image photographing unit 20, a control unit 30, and a communication unit 40. The sensor unit 10 collects data related to fire. The sensor unit 10 is a temperature sensor 110 for detecting a temperature and transmitting a temperature detection signal, a humidity sensor 120 for detecting a humidity and transmitting a humidity detection signal, a flame sensor for detecting a flame and transmitting a flame detection signal. 130 and a smoke sensor 140 for detecting the smoke to transmit a smoke detection signal. Sensors constituting the sensor unit 10 may be assigned unique identification numbers. The image capturing unit 20 may include cameras for capturing an area in which sensors constituting the sensor unit 10 are installed. The controller 30 performs a function of determining whether a fire has occurred by analyzing the detection signals transmitted by the sensors constituting the sensor unit 10 in combination.

For example, when additional sensors are installed in an area where sensors are installed, and the controller 30 analyzes detection signals transmitted by the sensors, and there is a sensor that transmits a detection signal informing of the occurrence of a fire, the detection signal is detected. The camera corresponding to the transmitted sensor may be controlled to photograph an area where the sensor is installed.

As an example, the control unit 30 weights the detection signals transmitted by the sensors constituting the sensor unit 10 so that the fire monitoring system including the composite fire detector is collected through various sensors installed in the monitoring site. By analyzing the data complexly according to the criteria set appropriately for the environment of the monitoring site, it is effective to improve the accuracy and reliability of judgment on the occurrence of fire. In addition, when the collected data for each detection signal is generated and any one of the collected data for each detection signal exceeds a preset fire determination threshold for each detection signal, it may be determined that a fire has occurred.

As another example, the controller 30 generates the collection data for each detection signal by assigning a weight to the detection signals transmitted by the sensors constituting the sensor unit 10, and a value obtained by adding the collection data for each detection signal is preset. If the combined fire determination threshold is exceeded, it may be configured to determine that a fire has occurred.

As another example, the control unit 30 generates collected data for each detection signal by assigning a weight to the detection signals transmitted from the temperature sensor 110, the flame sensor 130, and the smoke sensor 140, and generates the collected data for each detection signal. The fire determination reference values for the detection signals corresponding to the humidity values included in the humidity detection signal transmitted by the humidity sensor 120 are referred to by referring to the fire determination reference values storage unit for the detection signals, which are set to be proportional. The controller may be configured to determine that a fire has occurred when one of the collected data for each detection signal exceeds a selected fire determination reference value for each detection signal.

As another example, the controller 30 generates collected data for each detection signal by weighting the detection signals transmitted by the temperature sensor 110, the flame sensor 130, and the smoke sensor 140, and is proportional to the humidity value. The composite fire determination reference value storage unit configured to store the composite fire determination reference value is stored in the selected composite fire determination reference value corresponding to the humidity value included in the humidity detection signal transmitted by the humidity sensor 120, and collected data for each detection signal If the sum of these values exceeds the selected composite fire determination criteria, it may be configured to determine that a fire has occurred. The communication unit 40 performs a function of performing communication with the outside under the control of the control unit 30. For example, the RS-485 communication unit 420 and the ZigBee (ZigBee) method for RS-485 communication. ZigBee communication unit 410 for communication of the "can be configured" is proposed.

On the other hand, in Patent Registration No. 10-1399739 as Prior Art 2 related to the automation refurbishment, a "wireless fire monitoring system" is disclosed.

2 of the prior art 2 is a diagram illustrating a conventional radio detector composed of a base and a detector body. The wireless fire monitoring system is fixed to the ceiling of a plurality of rooms R1, R2, and R3 of the building, and wireless signals S1 and S2 which sense fire conditions in a specific room and mutually identify a fire signal.

By the way, as described in the prior art 1 and 2, while transmitting a fire signal to a fire detector (automatic) or transmitter (manual)-> repeater-> receiver (P-type receiver), the emergency bell of the emergency alarm equipment in the event of a fire Alternatively, a fire alarm is generated through the siren system.

In other words, in the conventional fire fighting field, when a fire occurs, a wired cable is notified to existing detectors, transmitters, repeaters, and receivers after a fire detection. Fire detectors are also difficult to operate, so fire notifications from radio detectors or cable transmitters to radio repeaters and radio receivers or fire alarms from radio detectors and radio receivers to radio repeaters and radio receivers are essential. Although there is no development for this. In addition to this situation, unless early action is taken to respond promptly within the Golden Time in the early response of a number of disasters, 119 fires may be delayed by delays in arrivals of fire trucks, resulting in increased fires, flames, smoke and toxic gases. This leads to a significant increase in lives and property damage.
