The multi-detector 100 according to the present invention will now be described.

As shown in FIG. 2, a plate-shaped mount 110 is mounted on a ceiling, and the circuit unit 120 is fixed to the mount 110 to check whether there is an abnormality, A housing 130 fixed to the mount 110 is constructed.

As shown in FIG. 3, the mount 110 is formed with at least two through holes 113 through which a piece hole 115 to be mounted on a ceiling is perforated so that the string 140 can pass therethrough, It is preferable to configure such that it can hang. Therefore, as shown in FIG. 5, the tent can be bundled with the strap 140 so as to be suspended.

Also, it is preferable that the inlet hole 133 formed at the side of the housing 130 to receive the smoke is arranged as high as possible. The inlet hole 133 may be formed in the upper end of the housing 130, so that the inlet hole 133 may be formed with the mount 110. Therefore, as shown in FIG. 4, there is an advantage that the fire can be detected quickly because the smoke that has climbed up to the ceiling along the wall can quickly enter the inflow hole 133.

The circuit unit 120 includes a temperature sensor 121 for detecting heat, a smoke sensor 122 for detecting smoke, a carbon monoxide sensor 123 for detecting carbon monoxide, a human body sensor 124 for detecting the presence or absence of a human body, And an illuminance sensor L for sensing the illuminance is formed and connected to the temperature sensor 121, the smoke sensor 122, the carbon monoxide sensor 123, the human body sensor 124 and the illuminance sensor L, The control unit 125 is configured. The output unit 126 is connected to the control unit 125 to inform the user of a dangerous situation.

The illuminance sensor (L) and the human body sensor (124) are exposed to the outside of the housing (130).

The output unit 126 may include a speaker for generating a warning light or an alarm sound. Since the beacon is exposed to the outside of the housing 130, the beacon is visually confirmed, and a plurality of holes are formed in the housing 130 so that the sound of the speaker can be transmitted.

An RF transmitting and receiving unit may be used as an example of the near-infrared transmitting and receiving unit 127 connected to the controller 125. The door transmitting and receiving unit 127 may communicate with the nearby transmitting and receiving unit 127, (128). The door detection sensor 128 is configured to be capable of short-range communication and is separated from the circuit unit 120.

The control unit 125 activates the human body sensor 124 after receiving the signal of the door sensor 128 through the short distance transmitter-receiver unit 127 and operates the output unit 126 when the human body is sensed .

In addition, a Wi-Fi transmission / reception unit 129 connected to the control unit 125 is configured to communicate with a terminal connected to the Internet.

Accordingly, the terminal such as a smart phone or a tablet can receive a danger signal through the Wi-Fi transmission / reception unit 129 as a character or an alarm, and is transmitted to the control unit 125 So as to perform a setting function. The setting function includes, for example, a set temperature detected by the temperature sensor 121, a set concentration of smoke detected by the smoke sensor 122, a set concentration of carbon monoxide detected by the carbon monoxide sensor 123, A set illuminance of the illuminance sensor L, a set time from when the human body sensor 124 senses the human body to when it detects the next human body, and whether or not the crime sensor is set.

The setting function may be configured by connecting a button or a volume switch to the control unit 125 so that the setting function can be operated offline.

A method of detecting multiple signals using the multi-detector according to the present invention using the multi-detector 100 will now be described with reference to FIGS. 7 and 8. FIG.

Referring to FIG. 7, a security detection step S1 is performed for inputting a signal to the control unit 125 to set a key for security. The security case may be a terminal capable of communicating through the Wi-Fi transceiver 129 or the short-range transceiver 127. Or the button, the volume switch, or the like.

After the key establishment step (S1), the door opening detection step (S2) is performed in which the door detection sensor (128) detects opening of the door. That is, when the intruder opens the door, the door detection sensor 128 informs the control unit 125 of the intrusion state through the near-infrared transmitting / receiving unit 127.

After the door opening detection step S2, a human body sensor activation step S3 is performed in which the controller 125 applies electricity to the human body detection sensor 124 to activate it.

After the human body sensor activation step S3, if the human body detection signal is not sent from the human body detection sensor 124, the controller 125 feeds back to the pre-door opening step S2, And an alarm step S4 is performed in which the output unit 126 is activated when a human body detection signal is transmitted from the human body detection sensor 124. [ In the alarm step S4, a light emitting lamp or a speaker is operated to notify a dangerous situation.

After the alert step S4, the control unit 125 transmits a danger signal through the Wi-Fi transceiver unit 129 to the terminal (S5). That is, the danger signal transmitted through the Wi-Fi transceiver unit 129 may be transmitted to the personal terminal through the communication company server or may be transmitted to the police station or the fire station.

Since the detection method for crime prevention is set at night, it is possible to prevent intruders from intruding at night.

In addition, the present invention will be described with reference to FIG. 7, with reference to FIG. 7, which shows a human body detection method capable of grasping the state of the elderly living alone or a pet, etc. during a day.

A signal is inputted to the control unit 125 to turn off the gun when the crime prevention is performed and a key off step (T1) is performed when the crime prevention sensor 128 does not receive a signal. The security-related event can be determined to be a terminal that can communicate through the Wi-Fi transmission / reception unit 129 or the short-range transmission / reception unit 127. Alternatively, the setting may be canceled by the button, the volume switch, or the like.

An illuminance sensor activating step T2 is performed in which the controller 125 activates the illuminance sensor L by applying electricity after the gun off step T1.

After the illuminance sensor activation step (T2), if the indoor illuminance is not equal to or higher than the set illuminance level, the controller 125 deactivates the human body sensor 124 and feeds back the illumination light to the illuminance sensor activation step (T2) If the indoor illuminance is equal to or higher than the set illuminance level, the illuminance detection step (T3) for activating the human body sensor 124 is performed. Generally, if the number is equal to or greater than 3 lux (LUX), it is sensed as a daytime so that the human body detection sensor 124 is activated.

After the illuminance detection step T3, the controller 125 determines whether there is an abnormality in the human body or not (step T4). That is, if the motion of the human body is detected within the set time in the daytime, it is determined as the normal state, and if the motion is not detected within the set time, it is confirmed as the abnormal state. In the case of an elderly or pet alone, it can be predicted that a heart attack or fainting is a serious situation if motion is not detected.

And an alarm step (T5) for operating the output unit (126) if an abnormal state is confirmed after the abnormality determination step (T4). The warning step T5 may be performed through a warning light or a speaker.

After the warning step T5, the control unit 125 transmits a danger signal through the Wi-Fi transceiver unit 129 to the terminal (T6). That is, the danger signal transmitted through the Wi-Fi transceiver unit 129 may be transmitted to the personal terminal through the communication company server or may be transmitted to the police station or the fire station.

The abnormality detection step (T4) may be performed after the human body detection sensor (124) detects the human body after the illumination detection step (T3) Feedback is performed between the sensing step T3 and the next step is performed.

If the human body detection sensor 124 does not detect the human body and the time is less than the set time, the human body detection sensor 124 is deactivated by feeding back to the illumination detection step T3, and then fed back to the illumination sensor activation step T2 , The human body detection sensor 124 does not detect the human body, and when the set time has elapsed, it is determined that the human body is in an abnormal state, and the process proceeds to the warning step T5. The warning step T5 may be performed through a warning light or a speaker. That is, after the human body is detected by the human body detection sensor 124, the feedback is repeated if the human body is not detected for the set time, for example, 3 hours. When the human body is detected within the set time, the set time is counted again. If the human body is not detected so that the set time has elapsed, it is determined that an accident has occurred and the alarm step T5 is performed.

A method of detecting whether or not a fire is caused only by temperature will be described with reference to FIG. 8 as follows.

The control unit 125 receives the signal from the temperature sensor 121 and feeds back the signal when the temperature is lower than the set temperature, and performs the alarm step P1 to operate the output unit 126 when the temperature is higher than the set temperature. That is, if a flame occurs and a sudden temperature of 60 ° C or more is detected, it is detected that a fire has occurred and an alarm step (P1) is performed. The alarm step P1 may be performed through a warning light or a speaker.

In addition, as a method of detecting whether or not a fire is caused through smoke and carbon monoxide, the following will be described with reference to FIG.

The control unit 125 receives a signal from the smoke sensor 122 and feeds back the signal when the concentration is lower than the predetermined concentration, and a standby step Q1 is performed to maintain the state when the concentration is equal to or higher than the predetermined concentration. The set concentration can be set to 15% / m as an example. The reason for going through the atmospheric stage (Q1) is to avoid mistaking the fire only by the smoke generated when the cigarette is smoked or cooked.

After the waiting step Q1, the controller 125 receives a signal from the carbon monoxide sensor 123 and feeds back the carbon monoxide when the carbon monoxide concentration is less than the set concentration, (Q2). The set concentration can be set to 30 ppm or more as an example. As such, the reason for sensing the carbon monoxide concentration is that carbon monoxide occurs simultaneously in the event of a fire.

In addition, a carbon monoxide sensing method capable of warning a dangerous situation by generating carbon monoxide even if smoke does not occur will be described with reference to FIG.

The control unit 125 receives a signal from the carbon monoxide sensor 123, feeds back the carbon monoxide if the carbon monoxide concentration is equal to or lower than the set concentration, and determines whether or not the set concentration of the carbon monoxide is maintained for a predetermined period of time or longer An alarm step R1 for operating the output unit 126 is performed. As an example, if a person persists for more than 70 ppm for 1 hour, more than 150 ppm for more than 10 minutes, or more than 400 ppm for more than 4 minutes, the danger will be alarmed. The alarm steps P1, Q2, and R1 may be performed through a beacon or a speaker. In this way, if the concentration of carbon monoxide alone is used to detect the danger, the gas burner alone in the tent or the hot air blower in the room for a long time may cause death due to carbon monoxide poisoning.

And a danger signal sending step in which the controller 125 transmits a danger signal to the terminal through the Wi-Fi transmission / reception unit 129 after the warning step (P1, Q2, R1). The alarm steps (P1, Q2, R1) can be made through a beacon or a speaker.

According to the present invention, as the smoke generated during the fire rises along the wall and reaches the ceiling, it flows into the inflow hole 133 of the housing 130, thereby promptly alarming the fire. In addition, since carbon monoxide is detected at the same time as the smoke generated in the fire, it is distinguished from the smoke generated in the non-fire, so that no error occurs when the fire is detected. In addition, since it can be easily mounted in the outdoor such as a tent, it is possible to prevent an accident caused by fire and carbon monoxide poisoning in the outdoors. In addition, when a person residing in the living room such as an elderly living alone is physically at risk, it automatically detects an abnormal situation and informs the outside of the risk without notifying the risk. In addition, since a single system can be used for crime prevention, human body detection (elderly living alone, indoor residence detection), and fire detection, it is possible to eliminate the burden of being separately installed.
