  It is a figure which shows one Embodiment of this invention.   It is a block diagram which shows the detail of one Embodiment of this invention.

An embodiment of the present invention is shown in FIG. In FIG. 1, the composite sensor units 1 to 4 are arranged so as to cover the living space of the resident in the residence. Furthermore, the composite sensor units 1 to 4 are connected to the controller 5 in the house via a wired or wireless communication unit 12. As the communication means 12 in the case of wired, for example, RS-485 that can perform multi-drop connection and half-duplex communication with a two-wire system is used. The controller 5 is a control device composed of a CPU, ROM, RAM, communication interface IC, and the like. The controller 5 is a warning light means 7 for inputting an out / in-room confirmation signal 13 from the door sensor 6 and blinking red, and a large volume. An output to the alarm sound means 8 for output is connected. In addition, a connection is made to a communication means 9 such as a public line for communicating with the outside. FIG. 2 shows details of the composite sensor unit 1 of the present invention. The human sensor 20 includes, for example, a pyroelectric infrared sensor having a peak wavelength of about 10 μm of infrared rays radiated from a human body temperature (36.5 ° C.) and a detection sensitivity to movement, and a lens. The human sensor 20 can have a configuration suitable for a wide area of the entire room and a spot-like detection depending on the installation location depending on a lens attached to the pyroelectric infrared sensor. The human sensor 20 detects human body temperature and movement, and does not detect lighting on / off, daytime brightness, darkness, TV or radio sound, etc. While the movement can be detected, if the room temperature exceeds 30 ° C. so that the temperature difference between the body temperature and the background disappears along with the movement of the human body, the resident's living state and behavior may not be detected. It is difficult to say that the human sensor 20 alone is sufficient to detect the resident's survival. As a supplement to the human sensor 20, a remote control operation detection sensor 21 comprising an infrared receiving module for detecting that a resident has operated a remote control transmitter such as a television, an AV device, an air conditioner, etc. is provided in the composite sensor unit. Are input to a one-chip microcomputer 23 having an I / O terminal. An infrared signal when a remote control operation is performed by the remote control operation detection sensor 21 is detected, and the number of remote control operations detected by the one-chip microcomputer 23 is counted and stored. The output of the human sensor 20 is also input to the I / O terminal of the one-chip microcomputer 23, and the number of movements of the resident is counted and stored. The illumination detection sensor 22 that detects that the illumination switch 28 is turned on / off is constituted by an alternating current sensor that detects a current flowing through the lamp line 14 connecting the illumination switch 28 and the illumination lamp 29. When the illumination switch 28 is off, the output of the illumination detection sensor 22 is zero, and when the illumination switch 28 is turned on, a current to the illumination lamp 29 flows through the lamp line 14, and as a result, the illumination configured by the current sensor. The detection sensor 22 detects whether the illumination switch 28 is on or off. The output of the illumination detection sensor 22 is input to the A / D converter terminal of the one-chip microcomputer 23 in the composite sensor unit 1 through a cable, signal processing is performed, and the number of operations of turning on and off the illumination switch 29 is counted. And memorized. The one-chip microcomputer 23 is connected to an interface IC 24 corresponding to the communication means 12 and receives a control signal from the communication means 12, for example, once per hour, Frequency), the number of detections by the remote control operation detection sensor 21 (the number of remote control operations by the resident), and the number of detections by the illumination detection sensor 22 (the number of times the lighting switch is turned on / off) are respectively connected to the controller 5 in the residence via the communication means 12. Sent to. The one-chip microcomputer 23 is cleared when transmission of each stored detection count is completed, and operates to store a new detection count. As described above, the composite sensor unit 1 includes a plurality of sensors that detect the living behavior of the resident such as the sensor for detecting the body temperature and movement of the resident by the human sensor 20 and the remote control operation detection sensor 21 or the illumination detection sensor 22. Consists of sensors. Furthermore, the composite sensor unit 1 has an audio output means 30 including an audio IC 25 in which audio information is stored in advance, an amplifier 26, and a speaker 27. The composite sensor units 2 to 4 also have the same configuration and the same function as the composite sensor unit 1. When a resident is present in the room, any abnormal state occurs, and no detection output is obtained from any of the composite sensor units 1 to 4, and when a predetermined time has elapsed, each composite sensor unit is controlled according to a control signal from the controller 5. Predetermined calling voices stored in advance from the voice output means 30 within 1 to 4 are output all at once. In addition, the controller 5 is unable to obtain a detection output from any of the composite sensor units 1 to 4, and when a predetermined time has elapsed, a primary determination of the resident's abnormality is performed and the communication unit 9 such as a public line is used. The first notification destination 10 is automatically notified. If necessary, it is automatically notified to the second reporting destination 11 as well. Normally, the controller 5 stores the number of detections detected from each of the composite sensor units 1 to 4, and is periodically transmitted to the first report destination 10 via the communication unit 9, for example, once every 12 hours. Although the first report destination 10 has a server (not shown), a history of the number of times of detection from each residence is stored, automatic association with the primary determination information of abnormality is performed, and the discovery of an accident, life or death of a single person, etc. Done. The door sensor 6 is a door lock having a contact output terminal linked to the door key. When the door sensor 6 is locked from the outside with a regular door key, a logic level “0” signal is output, and the door sensor 6 is unlocked with the regular door key. An out / occupancy confirmation signal 13 configured to output a signal of logic level “1” is input to the controller 5. When the resident is in the room, the logic level “1” of the out / in-room confirmation signal 13 is input to the controller 5, and the living state and the living behavior are detected as the resident safety confirmation mode by the composite sensor units 1 to 4. Is done through. When the outside / occupancy confirmation signal 13 from the door sensor 6 is output with a logic level “0” when the outside door is locked from outside with a regular door key, the controller 5 recognizes the absence of the resident and communicates. A control signal as a security mode is transmitted to the composite sensor units 1 to 4 through the means 12, and the composite sensor units 1 to 4 are operated as a security mode.
When a detection output from one of the composite sensor units 1 to 4, for example, the human sensor 20 is input to the one-chip microcomputer 23, it is immediately transmitted to the controller 5 via the communication unit 12. From the controller 5, a control signal for threatening voice output is transmitted to the folded composite sensor units 1 to 4. Voices that threaten unauthorized intruders stored in advance are simultaneously output from the voice output means 30 in the composite sensor units 1 to 4. Further, a flashing red light is output from the warning light means 7 connected to the output port of the controller 5, and an alarm sound having a large volume is output from the alarm sound means 8 connected to the output port of the controller 5.
