Description

  The present invention relates to an early detection device for lonely death that discovers the fact at an early stage when one or more residents living in a house die for any reason.

  In recent years, an aging society with a declining birthrate is progressing, and an increasing number of elderly people choose to live alone. For this reason, in urban areas, local communities are becoming sparse and human exchanges tend to be estranged, making it difficult to notice changes in neighbors. As a recent safety prevention system, many care-related services such as home-visit care and home-visit services, home health check services using personal computers, and systems using water and electric kettles that are used every day have been proposed. On the other hand, there are companies that provide home security services by utilizing mobile phones, wireless transmitters, and the like that have become popular due to the development of communication infrastructure. As related applications, there are a transmitter of Japanese Patent Laid-Open No. 7-95307, a safety confirmation device, Japanese Patent Laid-Open No. 11-110665, an accident detection device alone, and the like.

  However, according to the above technology, it is thought that the idea of the creator is somewhat based on the watching of the single person, and it is lacking in consideration for the caring side of the user, or to find a single life accident Is not enough. Therefore, this device was able to live without being aware of the device of the present invention by residents living in the dwelling, and in the unlikely event that the fact was lost, it was difficult to find the fact and malfunction, and died It is to provide a device for early detection of solitary death that can detect the person early and can quickly contact the outside.

  The present invention has been made in order to solve the above-described conventional problems, such as a pyroelectric infrared sensor having a peak sensitivity of 10 μm of infrared radiation emitted from body temperature (36.5 ° C.) and a detection sensitivity in motion. It is a survival detection sensor that is configured to integrate a human sensor with a rotating means and rotate intermittently at a speed that is about the speed of human movement. It is an early detection device for lonely death that detects the resident's body temperature.

  According to the present invention, it is possible to prevent a resident of a living living alone from dying for some reason in the room he / she is accustomed to living in, and preventing the body from deteriorating without finding the fact, and promptly contact the relevant parties. We hope for a peaceful Buddhist Buddha and can protect the living environment.

One embodiment of the present invention is shown in FIGS. The survival detecting means 1 to 4 are, for example, a human sensor composed of 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 detection sensitivity and a lens. 50, a geared DC motor 52, and a cam 51 are integrally constructed. FIG. When the motor drive signal 43 is input, the life detection means 1 is intermittently operated through a cam 51 within a predetermined rotation range (for example, 30 °) 53. The rotation speed of the survival detection means 1 is set to a occupant moving speed of 0.3 to 0.5 m / s when converted to a linear speed at a distance of 1.5 m to 2 m from the human sensor 50. The The survival detection means 1 to 4 configured in this manner rotate at the predetermined speed, so that even if the resident is stationary, the infrared peak wavelength radiated from the body temperature (36.5 ° C.) Since motion can be obtained with about 10 μm, the human sensor 50 can reliably detect the movement. Depending on the installation location, it is possible to obtain a human sensor 50 having a configuration suitable for a wide area of the entire room or spot-like detection by a lens attached to the pyroelectric infrared sensor. The living detection means 1 to 4 are arranged so as to cover the resident's dwelling action area (room, toilet, bath, kitchen (sink), etc.), so that the living detection in normal dwelling life. A detection output is obtained from any one of the means 1 to 4. When the living detection means 1 to 4 are not rotating, a survival detection output is obtained when there is a body temperature and movement of the resident, and when the resident is not moving, the survival detection means 1 to 4 By rotating by an intermittent operation, the presence or absence of the body temperature of the resident in a stationary state is detected. Since the life detecting means 1 to 4 do not detect lighting on / off, daytime brightness, darkness, TV or radio sound, etc., it is possible to reliably detect the living state of the resident regardless of the season or day and night. Although the survival detection means 1 to 4 have an amplifier and a binarization circuit (not shown), for example, the survival detection output 31 is logically determined according to the movement in the action area in the resident's residence. Level '1' is output. Since there are no residents in the house when going out, the survival detection output 31 is output with a logic level “0”. In addition, when the occupant has no movement during sleep in the room or does not move sideways, body temperature detection can be obtained during intermittent rotation, and the survival detection output 31 has a logic level “1”. Is output. A logical sum (OR) circuit 5 inputs the logic level output from the survival detection means 1 to 4, and if there is a logic level “1” at any of the inputs, the logic level “1” is set as the survival detection output signal 7. This is an output OR circuit. The lonely death determination means 9 is configured to perform a lonely death determination operation with the survival detection output signal 7 and the out / in detection signal 10 from the outing detection means 8 as inputs. A detailed configuration of the lonely death determination means 9 is shown in FIG. In FIG. 2, the counter 24 is configured to be able to count, for example, 24 hours as the first determination output 11, 36 hours as the second determination output 12, and 48 hours as the third determination output 13. Note that these determination times can be changed by a timer setting means 25 constituted by a switch or the like. The oscillator 20 shown in FIG. 2 outputs a clock signal 21 for causing the counter 24 to perform time counting. The clock signal 21 is input to a logical product (AND) circuit 22 and a logical product output clock signal 23 is output as a logical product (AND) operation result with the going-out / entrance detection signal 10. When the logical product output clock signal 23 is input to the counter 24, time counting is started. The counter 24 is configured such that the time count returns to zero each time the survival detection output signal 7 is input. Therefore, each time the survival detection output signal 7 is input, the time count of the counter 24 returns to zero, and the first determination output 11 is output only when the survival detection output signal 7 is not input for 24 hours or more. Is done. Similarly, when the survival detection output signal 7 is not input for 36 hours or 48 hours or longer, the second determination output 12 and the third determination output are output. These first determination output 11, second determination output 12, and third determination output 13 are input to the automatic notification means 14 in FIG. When the first determination output is input, the automatic notification means 14 issues a notification to a first predetermined place 16 such as a manager room or a management center that manages the residence via the public telephone line 15. A notification is sent to the second predetermined place 17 as necessary. The door sensor 6 that detects the opening and closing of the door in FIG. 1 includes an optical sensor, a magnetic sensor, and the like. The door sensor 6 attached to the entrance door of the house outputs a logical value “1” when the occupant opens and closes, for example, when the door is opened, and outputs a logical value “0” when the door is closed. It is configured. In FIG. 1, the outing detection means 8 is constituted by a flip-flop, for example, and outputs a logical value “0” to the out / in detection signal 10 when a door open signal “1” is input from the door sensor 6. The logical value “0” of the out / in detection signal 10 and the clock signal 21 are input to the logical product means 22, and the clock signal of the logical product output clock signal 23 is zero as the operation result of the logical product (AND) means 22. It is cut off. As a result, the counter 24 stops counting time, and the logical value “0” of the out / entry detection signal 10 is input to the counter 24 as a clear signal, so the count time so far is cleared and becomes zero. . A passage sensor 30 using an ultrasonic sensor, an infrared sensor, or the like is disposed inside the door and in the vicinity of the door. 8 flip-flops are set, and the logic value “1” as the entrance signal is output to the out / in detection signal 10. As a result, the gate of the logical product means 22 in FIG. 2 is released and a clock signal is input to the counter 24 as the logical product output clock signal 23, and clearing is released and time counting is performed. When the occupant crosses the passage sensor 30 for going out, the outing detecting means 8 determines that the room is still in the room, returns from the outside, opens the door, and when the detection output is obtained from the door sensor 6, Since it is determined that the user has yet to go out and the room is re-entered only after the passage sensor 30 is crossed, malfunction can be prevented.
The predetermined place 16 of the manager room or the management center that manages the house is connected to the telephone line 15 by a personal computer (not shown) through a modem, and can receive and display automatic notification information. Further, an alarm or the like may be issued as necessary. Similarly, a telephone call can be made to the second predetermined place 17 via the telephone line 15. The automatic notification means 14 includes a plurality of IDs for specifying a resident's residence in advance, a first elapsed time, a second elapsed time, a third elapsed time, etc. from the survival detection means 1 to 4. Is stored in advance, and the stored information is automatically notified in response to the first determination output, the second determination output, and the third determination output as inputs. . Although not shown, the DC power supply to the survival detection means 1 to 4, the logical sum means 5, the door sensor 6, the going-out automatic judgment means 8, the lonely death judgment means 9 and the automatic notification means 14 shown in FIG. It is configured to perform battery backup.
Next, the operation of the survival detecting means 1 to 4 of the present invention will be described with reference to FIGS. The timer 40 receives a clock signal from the oscillator 20 and performs time counting for determining an intermittent operation. The timer 40 outputs an intermittent operation signal 42 every 30 minutes, for example. When the intermittent operation signal 42 is input, the motor control circuit 41 outputs a motor drive signal to the geared DC motor 52, and operates so as to rotate a predetermined number of times (for example, three rotations) and stop. Since the rotation speed of the geared DC motor 52 is set to a large gear ratio, for example, it is set to 1 rotation / second. The cam 51 is configured to change the rotation of the DC motor 52 with gear into a rotation operation of a rotation range 53 and rotate the human sensor 50 by, for example, 30 °. Therefore, the human sensor 50 is a block diagram showing details of an embodiment of the present invention three times by one intermittent operation signal 42. A 30 ° rotation operation is performed. It should be noted that the human sensor 50 is constantly detecting an infrared peak wavelength of about 10 .mu.m emitted from a human body temperature (36.5.degree. C.) and a movement even during a time other than the rotation operation.

Effects of the embodiment

  According to the embodiment of the present invention, in addition to detection of survival when the resident is moving in the action area in the dwelling, the peak wavelength of infrared rays emitted from the body temperature (36.5 ° C.) is 10 μm and the movement. A human sensor such as a pyroelectric infrared sensor having detection sensitivity is integrated with the rotation means, and is configured as a life detection means so as to rotate intermittently at a speed about the speed of movement of a person. Since it is possible to detect the presence or absence of the body temperature of a stationary resident without any action or movement in the residence, the survival detection can be reliably detected without malfunctioning. Furthermore, since a plurality of the survival detection means are arranged so as to cover the resident's in-home action area, there is no omission of survival detection. Furthermore, since the out-going detection of going out or entering the room is reliably performed, a malfunction is avoided.
