The sensor may be installed in a plurality of places (ceiling, pillar, wall, etc.) in a room (house, office, etc.) to accurately detect various risk factors.

In addition, at least one of a temperature sensor, a vibration detector, a noxious gas detector, and an infrared detector may be used as the sensor 322. For example, when the temperature sensor measures a value of a room temperature or a temperature of the sensor portion above a threshold value, the temperature sensor may determine a dangerous environment and contact the relief management system 230. In addition, even when the vibration detector detects a vibration such as an earthquake or the collapse of a building, when the vibration is equal to or more than a predetermined value, the risk detector 320 determines that it is a risk factor. In addition, the noxious gas detector may detect gas such as propane gas and butane gas by investigating the concentration of indoor air, and may be set to determine a dangerous situation when the concentration of carbon monoxide or nitric oxide is above a reference value. . In addition, the infrared detector can be installed in an indoor space that requires a lot of security, and can detect movement by using invisible infrared rays when an external intruder enters. In addition, by installing a CCTV camera may visually transmit the current danger situation to the relief management system 230. Therefore, if a plurality of sensors are located throughout the room, it is possible to easily detect the risk factors occurring in the room. The signals detected by these sensors are transmitted to the risk management unit 330 by the control unit 310 through the short range communication unit 321.

That is, the short range communication unit 321 transmits the emergency signal detected by the at least one sensor 322 to the risk management unit 330 using short range communication. Bluetooth, infrared communication (IrDA), Zigbee, Wireless Fidelity (Wi-Fi), and Ultra Wide Band (UWB) may be used as the local area communication unit 321.

The emergency signal may be transmitted to the detection signal receiver 331 by the controller 310, and the emergency signal may be detected and generated by the sensor 322 according to a real time or a predetermined time interval.

The relief signal generator 332 generates the relief signal by comparing the received emergency signal for each risk factor with a threshold. When the emergency signal is detected by the user or the person of the emergency alert system 210 or more than a predetermined threshold, a corresponding relief signal is generated. If not, it may be controlled not to judge the detected emergency signal. That is, for example, when the harmful gas detector detects a vehicle exhaust gas temporarily detected through a window, a door, etc., it does not need to generate the relief signal when it does not last for a predetermined time, so that it can be excluded. In addition, the user may adjust the sensitivity so that the infrared sensor does not react sensitively to small movements such as insects or mice. In addition, since the emergency signal may be generated differently depending on the level of temperature, the degree of vibration, the amount of harmful gas, and the like, the relief signal generator 332 indicates that the vibration is weak when the vibration is weak. In the middle of the vibration, the middle vibration, in the case of very strong shaking, such as a strong vibration to display differently so that the user can conveniently understand the degree of the dangerous situation.

As shown in 410 of FIG. 4, the emergency signal message may be received by the user's mobile communication terminal 250 in the form of a text service. Since risk factors may occur in multiple locations, the specific location of the area where the emergency signal is generated can be displayed first, and the types of risk factors can be displayed. The emergency signal message may be a short message, a multimedia message, a long message, or an integrated message transmitted / received through a short message service (SMS), a multimedia message service (MMS), a long message service (LMS), or a unified message service (UMS). It may be transmitted to one or more communication terminals by either means.

In addition, referring to 420 of FIG. 4, the user may check the risk factor and the situation in which the risk factor progresses in more detail by pressing a specific button. That is, the temperature of the current room temperature may be measured to give a specific value or may indicate how high the degree is relative to the room temperature. In addition, not only the temperature but also the specific situation of the smoke such as vibration or harmful gas can be notified so that the user can more accurately grasp. Also, when each element reaches a certain value, a corresponding message may be output (for example, "Do not approach because it may threaten the body", "Please wear protective gear, gas mask").
