In modern society, the residential environment is undergoing drastic changes in the use fuel, residential system, and so on.

Domestic residential environment and use of gas, which are concentrated in high-rise areas, are extended to secondary accidents caused by fire or explosion in the event of gas accidents caused by careless use of gas, damage of intention or deterioration of facilities, resulting in massive casualties and property damage. Therefore, it is important to comply with the safety regulations required for gas use and facility installation, and to secure safety facilities.

Gas accidents are steadily declining until 2014, peaking at 264 cases in 2007, and injuries are also on the decline. The major cause of the accident reduction is attributable to the expansion of the supply of various gas safety facilities such as multifunctional meters, timer cocks, fuse cocks, and residential kitchen automatic fire extinguishers, have.

For example, a fuse-cock can prevent gas leakage due to intentional damage at an inexpensive price, but it has a disadvantage that it can not prevent leakage due to minute leakage and carelessness in use.

In addition, the timer cock is equipped with a mechanical or electronic shut-off device on the fuse-cock to automatically shut off the gas by setting the operating time, and can automatically shut off the gas when a gas leak is detected by a fire or gas detector. On the other hand, it is difficult to supply due to installation cost and purchasing cost, low technical difficulty required for product manufacturing, low price products due to worsening competition in the market, and only the performance of Korea Gas Safety Corporation There is a disadvantage that the reliability and safety of the product can not be guaranteed.

In addition, the multifunctional gas safety meter detects leakage of gas inlet piping, and is equipped with an earthquake sensor to prepare for gas leakage and earthquake. However, since it is installed outside and can not be operated indoors by users, The supply is not spreading.

This automatic kitchen fire extinguishing system can function as a gas barrier and prevent fire, and it is easy to supply gas safety devices sold in the market based on the installation law, and can be sold after the type approval of KFAS and Korea Gas Safety Corporation. Therefore, product reliability and safety are the highest.

The operation of the receiver-integrated automatic fire extinguishing system according to the present invention will be described in detail with reference to FIGS. 2 to 8. FIG.

The present invention combines the application of the Internet (IoT) technology with a multi-sensor (an earthquake sensor, a smoke detector, a gas detector, a temperature sensor) and integrates a receiving unit with the fire extinguisher 106 to increase the cost While performing gas shutoff and automatic fire extinguishing functions efficiently.

To this end, communication modules are added to the seismic sensor 101, the smoke detector 102, the gas detector 103, and the temperature sensor 104, respectively, so that the sensed signals are easily transmitted through wireless communication. Here, each sensor and temperature sensor serves as a sensor based on the object Internet.

For example, the earthquake sensor 101 detects an earthquake using an acceleration sensor. Figure 7 is an example of seismic acceleration using a vibrator (El-Centro seismic wave). Detecting an earthquake using an acceleration sensor is a known technique, so a detailed description thereof will be omitted. The earthquake detection signal is converted into a radio signal by using a communication module and is transmitted to the fire extinguisher 106.

In addition, the smoke detector 102 senses smoke caused by a fire using a smoke sensor such as an ion-type sensor or an optical sensor, converts the smoke detection signal into a wireless signal through a communication module, and transmits the wireless signal to the fire extinguisher 106 .

5 is a flow chart of the operation of the smoke detector 102. As shown in FIG. If power is supplied, the initialization operation is performed as in step S11, and the battery voltage is measured in step S12. Next, if the measured battery voltage is at the low voltage level, the process proceeds to step S13 to generate a warning sound for the battery low voltage. When this beep occurs, the user changes the battery of the smoke detector so that smoke detection is continuously performed. If the battery voltage is equal to or higher than the low voltage level, the process proceeds to step S14 to detect smoke. If smoke is detected as a result of the smoke detection, the process proceeds to step S15 to output a fire warning sound. The smoke detection signal sensed in step S16 is transmitted as a radio signal through the communication module to the fire extinguisher 106.

In addition, the gas detector 103 senses gas when power is supplied.

6 is a flowchart showing the gas detection operation of the gas detector 103. In step S21, if a gas leak is detected and if no gas leak is detected, the process goes to step S22 to turn off the LED, which is a gas detection indicator, If a leak is detected, the process goes to step S23 to turn on the LED, which is the gas detection indicator. Next, the gas sensing signal sensed in step S24 is converted into a wireless signal by using the communication module and is transmitted to the fire extinguisher 106.

The temperature sensor 104 senses temperature using sensors such as a thermocouple, a temperature measuring resistor, a thermistor (NTC), a metallic thermometer, a nuclear quadrupole name, an ultrasonic wave, and an optical fiber. Converts it into a wireless signal through the communication module, and transmits the wireless signal to the fire extinguisher 106.

The fire extinguisher 106 receives the sensed signals sensed by the seismic sensor 101, the smoke sensor 102, the gas detector 103 and the temperature sensor 104 in real time or periodically using the receiving unit 111 . Then, the detection signal analyzing unit 112 analyzes each of the detection signals received by the receiving unit 111 to determine whether there is an abnormality, performs a control operation according to circumstances when an abnormality occurs, and automatically performs gas blocking and fire prevention operations do.

For example, the seismic signal analysis unit 112a of the sensing signal analysis unit 112 analyzes the seismic signal received by the reception unit 111, and the analysis result is information for determining occurrence of an earthquake, And transfers it to the control unit 113. In order to analyze the earthquake detection signals, JMA of the Japan Meteorological Agency, Rossi-forel of Europe, US Coral Mercalli Grade, and MM Progress Grade are available. In other words, the acceleration signal, which is the detected earthquake detection signal, is compared with the set magnitude grade to analyze whether an earthquake has occurred and, if an earthquake has occurred, the degree of magnitude. For this purpose, it is desirable to use the maximum acceleration depending on the seismic grade and the magnitude class. Figure 7 is an example of seismic acceleration using a vibrator.

In addition, the smoke detection signal analyzer 112b analyzes the smoke detection signal received by the receiver 111, and transmits the analysis result to the operation controller 113 for each situation as information for determining occurrence of a fire.

The gas sensing signal analyzer 112c analyzes the gas sensing signal received by the receiver 111 and transmits the analysis result to the operation controller 113 for each situation as information for determining gas leakage. For example, pressure fluctuations measured using a pressure sensor are detected to analyze the gas leakage and the use state of the gas appliance.

Next, the temperature sensing signal analyzing unit 112d analyzes the temperature sensing signal received by the receiving unit 111, and transmits the analysis result to the context-based operation control unit 113 as information for determining occurrence of a fire . The temperature sensing signal analysis compares the received temperature with a predetermined temperature to determine a fire, determines fire occurrence, and transmits the analysis information to the situation-specific operation control unit 113.

The context-based operation control unit 113 recognizes an abnormal situation based on the analysis result analyzed by the detection signal analysis unit 112. For example, the presence or absence of the occurrence of an earthquake is determined by the analysis information of the seismic detection signal, the presence or absence of the fire is determined by the smoke detection signal analysis information, the presence of the gas leakage is determined by the gas detection signal analysis information, It is determined whether a fire has occurred or not.

If it is determined that an abnormal situation has occurred as a result of the determination, an operation control signal is transmitted to the gas circuit breaker 107. In accordance with the operation control signal, the gas circuit breaker 107 automatically operates to shut off the gas. The gas shut-off operation is accomplished by closing the gas shut-off valve using a solenoid.

In addition, when the abnormal situation is determined as a fire, the gas circuit breaker 107 is operated to shut off the gas automatically, and the fire extinguishing liquid (or water) is sprayed through the nozzle 105 to perform the fire extinguishing operation automatically do.

If it is determined that an abnormal situation has occurred, the fire extinguisher 106 transmits abnormal situation occurrence information to the situation information generation unit 114 to notify the remotely located user in real time. The context information generation unit 114 generates context information corresponding to the transmitted abnormal situation occurrence information and transfers the generated context information to the context information transmission unit 115. [ Here, the situation information may be information such as earthquake occurrence, gas leakage occurrence, fire occurrence.

The situation information transmitting unit 115 converts the situation information generated by the situation information generating unit 114 into a radio signal in a format suitable for the user terminal 200 and transmits the converted radio signal to the user terminal 200 do. Here, the situation information transmitting unit 115 preferably converts the situation information into a text message such as SMS or MMS, and transmits the converted status information to the user terminal 200. The situation information transmitting unit 115 transmits status information in the form of a text message to the user terminal 200 in cooperation with a text message server, a data server, a mobile communication server, and the like.

Accordingly, when the user is remotely located, the user is aware of the situation of the site (residential place) in real time. In case of gas leaks or fires in the field, it is notified to the relevant authorities so that follow-up actions can be taken promptly, thereby preventing loss of property or loss of property due to gas leakage, earthquake or fire .

FIG. 8 is a flowchart showing a sensing signal reception and analysis in the fire extinguisher of the present invention, and a control operation according to the occurrence of a situation.

As shown in the figure, in step S31, an initialization operation is performed when the power is turned on, and when the initialization operation is completed, the detection signal is received in step S32. In step S33, the received signal is analyzed using a detection signal analysis algorithm. Here, the detection signal analysis algorithm means the above-described seismic detection signal analysis process, smoke detection signal analysis process, gas detection signal analysis process, and temperature sensing signal analysis process.

After the received sensing signal is analyzed, the process proceeds to step S34 where it is checked whether gas leakage is detected. If a gas leakage is detected, the process proceeds to step S35 to operate the gas circuit breaker 107 to perform the gas shutoff operation.

If it is determined in step S36 that a fire has occurred, the process proceeds to step S37 to operate the gas circuit breaker 107 to perform a gas shutoff operation. In step S38, the fire extinguishing device is automatically operated And the automatic fire extinguishing function is performed through injecting the digestive liquid through the nozzle 105. Although the gas-shielding operation and the driving operation of the fire-extinguishing apparatus have been described in the foregoing description, the present invention is not limited thereto. The present invention is not limited to this, It is possible to simultaneously operate the gas shut-off operation and the fire extinguishing device.

As a result of analyzing the received sensing signal, if it is an earthquake detection as in step S39, the process goes to step S40 to perform a gas shutoff operation.

After performing the safety operation according to each of the situations thus generated, the process proceeds to step S41 to generate status information corresponding to the generated status, and the process proceeds to step S42 and transmits the generated status information to the user terminal 200 do.

As described above, the present invention simplifies the structure of the entire automatic fire extinguishing system by integrating the receiving unit into a fire extinguisher, which is indispensably provided in the residential automatic fire extinguishing system, and detects the situation through a sensor based on the object Internet by connecting the IoT technology to the multi- And the fire extinguisher automatically cuts off the gas and drives the fire extinguishing device so as to perform a safety operation in case of an earthquake, a gas leakage, or a fire, thereby preventing loss of life or property loss.

In addition, by transmitting the situation information to the user terminal located remotely from the fire extinguisher in real time, the user can recognize the situation of the residential place in real time from the remote location, and follow- And it is possible to prevent personal injury or property loss due to a primary accident.
