Abstract

PROBLEM TO BE SOLVED: To arrange a sensor for sensing the movement of a human body at the almost center of an indoor ceiling and to prevent the decline of the sensitivity of the sensor at the corner of a room. SOLUTION: Output signals from the sensor 5 equipped on a lighting fixture 3 attached at the almost center of the ceiling 2 inside the room 1 for sensing the movement of the human body 4 of an aged person or the like are supplied through indoor wiring (communication channel) 6 to a communication channel 7 and this monitoring device can monitor the movement of the human body 4 through the communication channel 7. As the sensor 5, a pyroelectric infrared ray sensing element for outputting signals in the case that the human body 4 moves is appropriate. To the communication channel 7, a so-called monitoring center 12 is connected. Also, monitoring can be performed by a portable telephone set 13 from the outdoors. It is preferable that the output signals from the sensor 5 are generated as abnormal signals in the case of not sensing the movement of the human body 4 over prescribed time (one hour, for instance).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device capable of monitoring mainly the movement of an elderly person through a communication line.

[0002]

2. Description of the Related Art A monitoring device is known in which an output signal from a sensor for sensing the movement of an elderly person living alone in a room is supplied to a communication line, and the movement of a human body can be monitored through the communication line.

[0003]

In such a monitoring apparatus, the sensor is mounted on a wall surface in a room or on a ceiling surface different from a lighting fixture installed on the ceiling. In the former case, the sensing sensitivity at a position distant from the wall surface decreases. In the latter case, the sensor and the lighting fixture are separately mounted on the ceiling, making it unsightly, and the lighting fixture is usually installed in the approximate center of the ceiling, so the sensor mounting location is necessarily near the ceiling. Since the sensor is separated from the center, the sensing sensitivity at a position separated from the sensor is likely to decrease. In view of the problems to be solved, the present invention has an object to provide a sensor for detecting the movement of a human body at substantially the center of a ceiling in a room, and to prevent a decrease in the sensitivity of the sensor at a corner in the room. .

Means for solving the problems are as described in the claims.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention will be described based on matters unique to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

In the illustrated embodiment, an output signal from a sensor 5 which is mounted on a lighting fixture 3 attached to a substantially center of a ceiling 2 of a room 1 and senses the movement of a human body 4 such as an elderly person receives indoor wiring (communication line) 6. Is a monitoring device that is supplied to the communication line 7 via the communication line 7 and can monitor the movement of the human body 4 through the communication line 7. As the sensor 5, a pyroelectric infrared sensing element that outputs a signal when the human body 4 moves is appropriate.

The sensor 5 is preferably provided substantially at the center of the lower surface of the lighting apparatus 3, and the output signal of the sensor 5 is sent to the indoor wiring 6 via a signal processing unit 8 which is logically processed by a microcomputer or the like. Is output as The indoor wiring 6 is connected to a communication line 7 via a line control device 9.

The indoor wiring 6 is preferably different from the commercial AC power supply line for supplying power to the lighting equipment 3. However, even if a so-called power line carrier system in which an output signal from the sensor 5 is superimposed on the commercial AC power supply line is adopted. Good. In this case, the signal processing unit 8 and the line control device 9 may be respectively connected to a commercial AC power supply line via a known coupler. It is preferable that a telephone 10 can be connected to the line control device 9. In addition, 11 is a lamp built in the lighting fixture 3.

A communication line 7 has a so-called monitoring center 12.
Is connected. It is also possible to monitor from outside by the mobile phone 13. Reference numeral 14 denotes a base station capable of wireless communication with the mobile phone 13, and the base station 14 is connected to the communication line 7. In addition, monitoring is not always performed from outside,
For example, monitoring may be performed from a centralized management room in a nursing home via an indoor communication line. Further, the communication line is not limited to a wired line, but may be a wireless line.

The movement of the human body 4 is detected by detecting the movement of the infrared ray 15 generated from the human body 4 by the sensor 5.
An output signal is generated. When an abnormality occurs in the human body 4, the human body 4 stops moving, and the output signal of the sensor 5 stops.
Even if there is no abnormality, the output signal of the sensor 5 is not generated when the human body 4 is stationary. Therefore, the sensor 5
When there is no output signal, it is preferable that the signal processing unit 8 determines that there is an abnormality. Therefore, the output signal from the sensor 5 may be generated as an abnormal signal when the movement of the human body 4 is not detected for a predetermined time (for example, one hour).

According to the present embodiment, the sensor 5 for detecting the movement of the human body 4 can be arranged substantially at the center of the ceiling 2 of the room 1, so that the sensitivity of the sensor 5 at the corner of the room 1 can be prevented from lowering. Since the lighting fixture 3 is equipped with the sensor 5, the ceiling 2 is neat.
