Description

The present invention relates to a lighting device, a biological movement detection system, a biological movement detection method, a program, and a recording medium.

With the aging of the elderly in recent years, the number of lonely deaths of the elderly is increasing, which has become a social problem. Due to this situation, especially in the case of elderly people living alone, when renting a dwelling unit, there are many cases where the landlord who is concerned about lonely death refuses to move in. On the other hand, even if the landlord wants to rent a dwelling unit, he cannot rent it even though there are many people who want to move in, and there is a problem that vacant rooms are created. Therefore, it is desired to take measures to prevent the lonely death of the elderly and to detect the crisis at an early stage. This problem applies not only to the elderly, but also to, for example, persons with disabilities and sick people living alone.

Therefore, as a method for early detection of lonely death of a resident, for example, a system in which an abnormality detector is installed in a dwelling unit and an abnormality is detected is reported to a monitoring center (Patent Document 1). ..

However, it is costly to install a dedicated abnormality detector for each dwelling unit, and there is also a problem of installation space. Especially in the case of an apartment for living alone, the landlord owns a large number of units, so the hurdle for introduction is high.

The present invention is not limited or limited by the following embodiments. The descriptions in each embodiment can be referred to each other.

(Embodiment 1)
An example of the lighting device of the present embodiment and the detection system using the lighting device will be described with reference to FIG. FIG. 1 is a schematic diagram showing an overall configuration when the lighting device and the detection system are used. The lighting device 10 is attached to the room of the dwelling unit 1 of the subject 2, and the magnetic detection device 40 is attached to the vicinity of the door 50 of the dwelling unit 1. On the other hand, the watcher 3 who wants to know the state of the target person 2 carries the terminal 30. The lighting device 10 and the terminal 30 can be connected to each other via the communication network (network) 20, and the lighting device 10 and the magnetic detection device 40 can communicate with each other. The communication method between the lighting device 10 and the magnetic detection device 40 is not limited as described later, but will be described below by taking wireless communication 40A as an example.

In the dwelling unit 1, the room in which the lighting device 10 is attached is not particularly limited. The dwelling unit 1 generally has a plurality of rooms such as a bedroom, a living room, a kitchen, and a toilet. According to the detection system of the present embodiment, analytical data indicating whether or not the subject 2 is in the dwelling unit 1 and whether or not the subject 2 is moving in the dwelling unit 1 can be obtained. Therefore, the lighting device 10 may be attached to, for example, all the rooms or the room where the subject spends a long time (for example, a living room, a bedroom, etc.).

The lighting device 10 may be, for example, for ceiling installation or wall installation, and is preferably for ceiling installation. By installing the lighting device 10 on the ceiling, for example, it is possible to detect biometric information in a wider range.

In the dwelling unit 1, the door 50 to which the magnetic detection device 40 is attached includes, for example, a room door and an entrance door, and the entrance door is particularly preferable. The location where the magnetic detection device 40 is installed on the door 50 is not particularly limited. In the present invention, when analyzing the locking / unlocking of the door 50, for example, it is a position where a magnetic change due to switching between locking and unlocking can be detected, and when analyzing the opening / closing of the door 50, for example, the door 50. It is a position where magnetic changes due to switching between opening and closing can be detected.

The door 50 is locked, for example, by fitting the lock of the dead bolt (final tightening) of the door 50 into the corresponding strike (receptacle), and the door 50 is unlocked from the strike to the dead bolt. Is done by extracting. The locking / unlocking may be operated by, for example, a key or a thumb turn. The opening and closing of the door 50 is not limited to the locking / unlocking, but also means the opening / closing of the door 50 for people to enter and exit.

The method of generating the magnetic change by switching between locking and unlocking the door 50 and the magnetic change by switching the opening and closing of the door 50 is not particularly limited, and for example, a magnet can be used. It is preferable that the magnet is arranged at a position where the distance or angle with respect to the magnetic detection device 40 changes, for example, by switching the lock / unlock of the door 50 or opening / closing the door 50. As a result, a magnetic change can be generated by locking / unlocking the door 50 or opening / closing the door 50. As a specific example, FIG. 2 shows a form in which the magnet is arranged on the thumb turn 51 of the door 50. FIG. 2 is a schematic view showing the positional relationship between the thumb turn 51 of the door 50 and the magnetic detection device 40. In FIG. 2, a magnet 52 is fixed to the thumb turn 51. As shown in FIG. 2, for example, in the locked state of (A), the thumb turn 51 is in the horizontal direction, and in the unlocked state of (B), the thumb turn 51 is in the vertical direction. The distance of the magnet 52 fixed to the thumb turn 51 with respect to the magnetic detection device 40 changes between the locked state of (A) and the unlocked state of (B). Therefore, the magnetic detection device 40 can detect the magnetic change due to the switching between locking and unlocking by the thumb turn 51.

Further, the present invention is not limited to this, and for example, the magnet 52 may be fixed to the door 50 and the magnetic detection device 40 may be arranged on the door 50 frame side. In this case, when the door 50 is opened, the magnet 52 is far from the door 50 frame, and when the door 50 is closed, the magnet 52 is close to the door 50 frame. Therefore, the magnetic detection device 40 can detect the magnetic change due to the opening and closing of the door 50.

As described above, the communication method between the lighting device 10 and the magnetic detection device 40 is not particularly limited, and examples thereof include wireless communication 40A. In this case, for example, the lighting device 10 has a wireless communication unit as a communication unit with the magnetic detection device 40, and the magnetic detection device 40 has a wireless communication unit as a communication unit with the lighting device 10.

As the communication line network 20 connecting the lighting device 10 and the terminal 30, for example, a known communication line network can be used. The communication method is not particularly limited, and may be, for example, wired or wireless, and specific examples thereof include an internet line and a telephone line.

The terminal 30 may be connectable to the lighting device 10 via the communication network 20, and has, for example, a communication module. Further, the terminal 30 has, for example, a CPU (central processing unit), an output unit, an input unit, a storage unit, and the like, and each of them may be connected by an interface (I / F). The output unit is, for example, a display unit such as a display, an audio output unit, or the like. The terminal 30 is not particularly limited, and examples thereof include a portable terminal. Specific examples of the portable terminal include smartphones, tablets, mobile phones, wearable devices and the like. Examples of the wearable device include a wristwatch type, eyeglass type, ring type, shoe type, pocket type, pendant type and the like.

Next, an example of the lighting device 10 of the present embodiment will be described with reference to FIG. FIG. 3 is a block diagram showing an example of the lighting device 10. Note that FIG. 3 shows, for convenience, a connection with the terminal 30 via a communication network and a connection with the magnetic detection device 40 by wireless communication, as in FIG. The lighting device 10 has a lighting device main body 11. The lighting device main body 11 has a lighting unit 101, a biological information detection unit 102, a wireless communication unit 103 which is an example of the communication unit, a processing unit 104, and an output unit 105 to an external terminal. ..

The lighting device 10 is composed of a lighting device main body 11 and a cover member (not shown) that covers the lighting unit 101 and the like of the lighting device main body 11. That is, the lighting device main body 11 means a so-called basic structure of a lighting device, and includes, for example, a lighting unit 101 including a light source, a power supply unit, and the like for functioning as a lighting device. The configuration and structure of the lighting device main body 11 are not particularly limited, and as described above, the lighting device functions as a lighting device, and the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 are further added. It suffices if it can be installed. The form of the lighting device main body 11 is not particularly limited, and examples thereof include a ceiling light and a hanging pendant attached to a hook ceiling provided on the ceiling. The type of the light source of the illumination unit 101 is not particularly limited, and examples thereof include LEDs and organic EL. In the lighting device 10, for example, the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 are a substrate on the installation side in the lighting device main body and a diffusion cover provided on the illumination side (shown in the figure). It may be accommodated between and. The substrate is, for example, a main body substrate for fixing a light source such as an LED, a power supply circuit, or the like, and the diffusion cover is, for example, a cover that diffuses light emitted from the light source to reduce glare. The power supply unit is, for example, directly or indirectly connected to an external power source to supply electric power to the lighting unit 101, the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105.

Further, when lighting is unnecessary such as in the daytime, for example, by installing an automatic lighting device or the like, the biometric information detection unit 102, the wireless communication unit 103, and the processing unit 104 can be installed while the lighting unit 101 is turned off. , The output unit 105 can be operated.

The biological information detection unit 102 detects biological information in the space where the lighting device main body 11 is installed. The type of the biological information detection unit 102 is not particularly limited as long as it can detect biological information indicating the existence of a human body. As a specific example, the biological information detection unit 102 may be, for example, a motion sensor or a camera. The motion sensor 102 is preferable because, for example, the biological information detection unit 102 is inexpensive and does not require complicated information processing. The motion sensor may be, for example, a pyroelectric sensor or an infrared sensor, and the infrared sensor may be, for example, an array type in which a plurality of sensors are mounted. The human body emits infrared rays. Therefore, for example, if infrared rays in a space are detected by the motion sensor, the presence or absence of a living body and the movement of the living body in the space can be analyzed by the processing unit 104 described later from the biological information detection data. Further, in the case of a camera, if an image of the space is captured, the presence or absence of a living body and the movement of the living body in the space can be analyzed by the processing unit 104 described later from the captured data (the biological information detection data).

As described above, the lighting device 10 is preferably installed on the ceiling, for example, but may be on a wall or under the floor. The biometric information detection unit 102 mounted on the lighting device 10 can detect biometric information in the region 4 surrounded by the dotted line circle in FIG. 1, for example. The region 4 is also hereinafter referred to as a detection region 4. The size of the detection area 4 is not particularly limited, and is appropriately determined by, for example, the type and number of biometric information detection units 102 mounted on the lighting device 10, the height of the ceiling to which the lighting device 10 is attached, the size of the room, and the like. Can be set. The detection area 4 by one lighting device 10 can be assumed to be 1K, for example, from a general floor plan for a single elderly person.

In the lighting device 10, the communication unit for the magnetic detection device 40 is not particularly limited as described above, and the wireless communication unit 103 can be exemplified. The wireless communication unit 103 can wirelessly communicate with the magnetic detection device 40, which is an external device different from the lighting device 10. Then, the wireless communication unit 103 receives the magnetic detection data transmitted from the magnetic detection device 40 and transmits it to the processing unit 104.

In the lighting device 10, the biometric information detection data detected by the biometric information detection unit 102 is sent to the processing unit 104 and analyzed as described later. The communication between the biometric information detection unit 102 and the processing unit 104 is not particularly limited, and may be, for example, communication between circuits via a bus or wireless communication via a wireless communication unit. In the latter case, the wireless communication unit 103 can be used as the wireless communication unit. The wireless communication unit 103 can wirelessly communicate with the processing unit 104 in the same lighting device 10. Then, the wireless communication unit 103 transmits the biometric information detection data detected by the biometric information detection unit 102 to the processing unit 104. The wireless communication unit 103 is not particularly limited as long as it can wirelessly connect between the biometric information detection unit 102 and the processing unit 104 mounted in the same lighting device 10.

The wireless communication method of the wireless communication unit 103 is not particularly limited, and examples thereof include IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.15.1 and IEEE 802.15.4. The IEEE 802.15.1 is, for example, a standard for Bluetooth®, and the IEEE 802.15.4 is, for example, a standard for ZigBee®. Other examples include RFID, infrared communication (IrDA), UWB, and the like.

The processing unit 104 analyzes the presence / absence of a living body and the presence / absence of movement of the living body based on the biological information detection data. As described above, when the biometric information detection data is the infrared detection data, for example, when the infrared data in an unmanned state is used as a threshold value and the detection data showing a significant difference with respect to the threshold value is obtained, the space. It can be judged that there is a person in. Further, when the detection data showing a significant difference with respect to the threshold value fluctuates with time, it can be determined that the person has moved in the space. The lighting device main body may further have, for example, a storage unit, and the storage unit may store information such as, for example, the threshold value as evaluation reference information.

Further, the processing unit 104 analyzes the locking and unlocking of the door 50 or the opening and closing of the door 50 based on the received magnetic detection data. As described above, for example, by arranging the magnetic detection device 40 and the magnet in the vicinity of the door 50, the door 50 is locked / unlocked, or the door 50 is opened / closed to generate a magnetic change. Can be done. Therefore, for example, the magnetic change due to switching between locking and unlocking the door 50 or the magnetic change due to the opening and closing of the door 50 is set as the evaluation reference information, and the magnetic detection data is compared with the evaluation reference information. , Locking and unlocking of the door 50, or opening and closing of the door 50 can be determined. The storage unit may store the relationship between the locking / unlocking switching of the door 50 and the magnetic change, and the relationship between the opening / closing of the door 50 and the magnetic change as the evaluation reference information.

The processing unit 104 may be, for example, a CPU. In the lighting device 10, the processing unit 104 is preferably a small device because it is mounted on a normal lighting device main body, for example. Examples of the small device include a small single boat computer, and specific examples include Raspberry Pi (registered trademark) and the like. The CPU is connected to other parts, for example, via an interface.

The output unit 105 transmits the analysis data obtained by the processing unit 104 to the external terminal 30 via the communication network 20. The output unit 105 may be, for example, a transmission / reception unit that transmits information to the external terminal 30 and receives information from the external terminal 30. The output unit 105 may be, for example, a communication module.

The illuminating device main body 11 may further have, for example, a storage unit. The storage unit can store, for example, biometric information detection data by the biometric information detection unit 102, magnetic information detection data by the magnetic detection device 40, analysis data by the processing unit 104, and the like.

When the external terminal 30 receives the analysis data from the output unit 105 of the lighting device 10 via the communication network 20, the external terminal 30 outputs the analysis data to, for example, the output unit. When the output unit is, for example, the display unit such as a display, the analysis data may be displayed on the display unit, and when the output unit is, for example, the audio output unit such as a speaker, the analysis. The data may be emitted as sound. As a result, the watcher 3 can grasp the state of the target person 2 from the external terminal 30.

When the external terminal 30 has the display unit, for example, the analysis data can be displayed as follows. It should be noted that this is an example and does not limit the present invention. In the following example, a smartphone as the external terminal 30 and a living room of the dwelling unit 1 as the installation location of the lighting device 10 will be described as an example. FIG. 8 is a schematic diagram showing an example of display of analysis data in the display unit 31 of the external terminal (smartphone) 30. As shown in FIG. 8, the analysis result 32 and the reception time 33 thereof are displayed in time series on the display unit 31 of the smartphone 30. The analysis result 32 is displayed as a message such as "The activity in the living room could not be confirmed at XX hours △△ minutes" or "The unlocking of the entrance door could not be confirmed at XX hours △△ minutes". Will be done. In addition, when the movement of the subject 2 is confirmed, for example, "the activity in the living room was confirmed at 0:00 △△ minutes", and when the unlocking of the entrance door is confirmed, for example, for example. A message such as "The unlocking of the entrance door was confirmed at 0:00 o'clock △△ minutes" is displayed. In addition, as shown in FIG. 8, the display unit 31 may also display the dwelling unit information and the name of the subject 2.

As shown in FIG. 1, the magnetic detection device 40 is a device installed near the door 50 of the dwelling unit 1, and has a magnetic sensor 401 and a wireless communication unit 402 as an example of the communication unit.

The magnetic sensor 401 is a sensor that detects magnetism, and in the present invention, for example, it detects a magnetic change due to locking and unlocking of the door 50, or a magnetic change due to opening and closing of the door 50. As the magnetic sensor 401, for example, a Hall element or the like can be used.

The communication unit may be communicable with the lighting device 10, and for example, the wireless communication unit 402 may be exemplified as described above. The wireless communication unit 402 can wirelessly communicate with the lighting device 10, and the wireless communication method thereof is not particularly limited and is the same as described above.

(Modification 1)
The lighting device 10 may further include a detection control unit 106, for example, as shown in the block diagram of FIG. The detection control unit 106 controls the start and stop of detection by the biological information detection unit 102. The detection control unit 106 is, for example, a CPU. Note that FIG. 4 shows, for convenience, a connection with the terminal 30 via a communication network and a connection with the magnetic detection device 40 by wireless communication, as in FIG.

By controlling the start and stop of detection by the biological information detection unit 102 by the detection control unit 106, for example, instead of performing continuous detection at all times, detection at a required time zone and intermittent detection are performed. It is possible to reduce costs such as electricity bills and save the capacity of recorded data. For example, the detection control unit 106 can start the detection by the biological information detection unit 102 at an arbitrary time interval, and can stop the detection by the biological information detection unit 102 when an arbitrary time elapses from the start of the detection.

When the biological information detection unit 102 obtains biological information detection data over time, the processing unit 104 analyzes, for example, the presence or absence of a living body and the presence or absence of movement of the living body from the biological information detection data received over time. .. By using the biometric information detection data over time, for example, it is possible to analyze in more detail that the subject is not in the room, that the subject is in the room but is not moving, that the subject is moving, and the like. ..

(Modification 2)
In the lighting device 10, for example, as shown in the block diagram of FIG. 5, the output unit 105 is a transmission / reception unit 405, and may further include an alert unit 107. As described above, the transmission / reception unit 405 transmits information to the external terminal 30 via, for example, the communication line network 20, and receives information from the external terminal 30. Further, when the transmission / reception unit 405 receives the alert information transmitted from the terminal 30, the alert unit 107 sends an alert. The alert unit 107 is, for example, a speaker, and the alert is, for example, a siren, a standard message, a real-time message of the watcher 3 as described later, or the like.

When the watcher 3 receives analysis data such as the subject 2 is not moving, the door 50 is not unlocked for a long time, the door 50 is not opened for a long time, etc. via the communication network 20. The watcher 3 can send a message from the terminal 30 to the lighting device 10 in real time via the communication network 20. Then, when the transmission / reception unit 405 of the lighting device 10 receives the message, the alert unit 107 of the lighting device 10 can send the message to the dwelling unit 1.

Next, the detection method of the present embodiment will be described with reference to the flowchart of FIG. The detection method of the present embodiment is carried out as follows, for example, by using the detection system of the present embodiment shown in FIG. 1 and the lighting device 10 shown in FIGS. 3 to 5. In the flowchart of FIG. 6, the steps surrounded by thick lines (S300, S301) show the steps executed by the magnetic detection device 40, and the others show the steps executed by the lighting device 10. The detection method of the present embodiment is not limited to the use of the detection system of FIG. 1 and the lighting device 10 of FIGS. 3 to 5.

Further, the lighting device 10 detects biological information in the space of the room in which the lighting device 10 is installed by the biological information detection unit 102 (S200). Then, the detected biometric information detection data is transmitted by the wireless communication unit 103 of the lighting device 10 to the processing unit 104 of the lighting device 10 (S201), and the processing unit 104 receives the data. Next, the processing unit 104 of the lighting device 10 analyzes the presence / absence of a living body and the presence / absence of movement of the living body in the space based on the received biological information detection data (S202). Then, the analysis data obtained by the processing unit 104 of the lighting device 10 is transmitted to the external terminal 30 via the communication network 20 (S203). This step (S200) to step (S203) are repeated, for example, continuously or intermittently.

On the other hand, the magnetic detection device 40 detects the magnetic change due to the locking and unlocking of the door of the dwelling unit 1 by the magnetic sensor 401 or the magnetic change due to the opening and closing of the door (S300), and the magnetic communication unit 402 detects the magnetic change. The detected magnetic detection information is transmitted from the detection device 40 to the processing unit 104 of the lighting device 10 (S301). Then, the lighting device 10 receives the magnetic detection information transmitted from the magnetic detection device 40 by the wireless communication unit 103, and transmits the magnetic detection information to the processing unit 104 of the lighting device 10. Next, when the processing unit 104 of the lighting device 10 receives the magnetic detection information, the processing unit 104 analyzes the locking / unlocking of the door 50 or the opening / closing of the door 50 based on the received magnetic detection data (S302). .. Then, the analysis data obtained by the processing unit 104 of the lighting device 10 is transmitted to the external terminal 30 via the communication network 20 (S203). From this step (S300) to the step (S302) and the step (S203) are repeated, for example, continuously or intermittently.

In the present embodiment, the steps related to lighting (S100), the steps related to biological information (S200) to (S202), the steps related to magnetic change (S300) to the steps (S302), and the steps (S203) are, for example, in parallel. It can be carried out. Further, the step (S100) related to lighting is optional, and another step may be performed without performing this step (S100). That is, for the lighting device 10, other steps may be performed regardless of whether the lighting is ON or OFF.

According to such a method, first, as the first embodiment, it is possible to detect the necessity of confirming the safety of the subject resident in the dwelling unit by, for example, detecting the movement of a living body in the dwelling unit. As a specific example, for example, in the step (S202), changes over time are analyzed regarding the presence / absence of a living body and the presence / absence of movement of the living body, and if there is no change, the target person of the dwelling unit 1 in which the lighting device 10 is installed is installed. The determination result that the safety confirmation of (resident) 2 is necessary can be transmitted as the analysis data to the external terminal 30 of the watcher 3 via the communication network 20. Further, when there is a change, the determination result that the safety confirmation of the target person 2 is unnecessary can be transmitted as the analysis data to the external terminal 30 of the watcher 3 via the communication network 20. Therefore, when the former transmission result is received, the watcher 3 goes to the dwelling unit 1, for example, calls out to the target person 2, or calls the target person 2, to make it more specific. You can take safety confirmation actions. On the other hand, when the latter transmission result is received, the watcher 3 can, for example, go to the dwelling unit 1 of the target person 2 or omit the telephone call to the target person 2 without confirming the safety.

Further, according to the above method, as the second form, for example, by detecting the locking / unlocking of the door or the opening / closing of the door, the safety of the subject resident in the dwelling unit is confirmed from a viewpoint different from that of the first form. Can be detected. As a specific example, for example, in the step (S302), when the door lock / unlock or the door opening / closing is analyzed and there is no change in the door locking / unlocking or there is no change in the door opening / closing for a long period of time. The result of the determination that it is necessary to confirm the safety of the target person (resident) 2 of the dwelling unit 1 in which the lighting device 10 is installed is used as the analysis data outside the watcher 3 via the communication network 20. It can be transmitted to the terminal 30. Further, when there is a change, the determination result that the safety confirmation of the target person 2 is unnecessary can be transmitted as the analysis data to the external terminal 30 of the watcher 3 via the communication network 20. Therefore, when the former transmission result is received, the watcher 3 goes to the dwelling unit 1, for example, calls out to the target person 2, or calls the target person 2, and is more specific. You can take safety confirmation actions. On the other hand, when the latter transmission result is received, the watcher 3 can, for example, go to the dwelling unit 1 of the target person 2 or omit the telephone call to the target person 2 without confirming the safety.

Further, the following determination can be made from the combination of the first form and the second form. That is, for example, in the step (S202), there is no change over time in the presence / absence of the living body and the presence / absence of the movement of the living body, and it is analyzed that the door is locked and unlocked or the door is opened / closed in the step (S302). If so, the determination result that the safety confirmation of the target person is necessary may be transmitted to the external terminal as the analysis data via the communication network. This is because if there is a change in the locking / unlocking or opening / closing of the door even though there is no change in the living body, for example, an intrusion of a suspicious person may be considered. On the other hand, in the step (S202), if there is a change over time in the presence / absence of the living body and the presence / absence of the movement of the living body, the determination result that it is not necessary to confirm the safety of the subject is used as the analysis data. It may be transmitted to the external terminal via the communication network. This is because it can be determined that the subject can move. In addition, if the movement of the living body is detected in the dwelling unit, then it is locked, and then the movement in the dwelling unit is not detected for a long time, there is a high possibility of going out or traveling, so it is necessary to confirm the safety. Will be low.

Further, as shown in the second modification, when the lighting device 10 further includes the alert unit 107, the steps as shown in the flowchart of FIG. 7 can be executed. That is, when the watcher 3 receives the analysis result of the target person 2 for which the safety confirmation is considered necessary at the terminal 30, the watcher 3 transmits the alert information to the lighting device 10 using the terminal 30. .. The alert information is, for example, a real-time voice message, a siren, a standard message, or the like of the watcher 3. Then, when the lighting device 10 receives the alert information by the transmission / reception unit 405 (S204), the alert unit 107 transmits the alert (S205).

In this way, by enabling bidirectional information communication between the lighting device 10 installed in the dwelling unit 1 of the target person 2 and the terminal 30 carried by the watcher 3, for example, the watcher 3 can be used. , The terminal 30 can be used to send a message or a siren confirming the safety to the target person 2. Further, the alert may be, for example, an alert notifying the occurrence of a disaster. Even if a disaster occurs around the dwelling unit, the subject 2 may not notice it. In such a case, by transmitting an alert notifying the disaster, the target person 2 can be notified of the disaster, for example, and urged to evacuate.

As described above, the lighting device 10 functions as lighting and detects the movement of a living body and the locking / unlocking or opening / closing of a door. The original lighting function, the detection of biological movement, and the locking / unlocking or opening / closing of the door may be performed in parallel, for example, while one of them is stopped and the other performs. It may have been done.

Since the lighting device 10 is normally supplied with electric power by turning on the main power source (for example, the wall power source), the lighting device 10 may or may not activate the lighting unit 101 of the lighting device main body. It is possible to activate the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105. However, it may be necessary to detect the subject regardless of whether the main power supply is turned on or off. Therefore, the lighting device 10 can detect the target person regardless of whether the main power supply is ON or OFF. Therefore, for example, the lighting device main body further includes at least one of the power storage unit and the battery unit. It is preferable to prepare. By providing the storage battery or the battery unit in this way, for example, even if the main power supply is turned off, the biometric information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output from the storage battery or the battery unit. It is possible to supply electric power to the unit 105 and activate them.

Even if the watcher requests the target person to keep the main power on at all times, for example, if the target person is an elderly person or the like, when the lighting by the lighting device 10 is turned off, the remote controller or the like is used instead of the remote controller. , The main power may be turned off. In addition, due to a disaster such as an earthquake or fire, the fuse may blow and the main power may be turned off regardless of the intention of the subject. However, if the lighting device 10 has such a form, for example, even when the main power supply is turned off, it can be detected by supplying power from a backup power source such as the power storage unit or the battery unit. , Safer and more secure watching is possible. Since the main power supply is always ON, a cover for preventing ON / OFF switching may be attached to the wall power supply (main power supply) in the room of the dwelling unit where the lighting device of the present invention is installed.

In the present invention, the subjects include, but are not limited to, elderly people, persons with disabilities, sick persons, and the like. The present invention can be used in a dwelling unit in which a subject who is concerned about being alone in the dwelling unit resides for the watcher. Specific examples of the subject include children, pets, and dementia patients with wandering habits. Normally, the child does not live alone in the dwelling unit, but for example, the child spends time alone in the dwelling unit during the time when the parent is absent due to work, shopping, going to the hospital, or the like. Even in such a case, the lighting device, the detection system and the detection method of the present invention are useful. Further, as described above, for example, it is not necessary to watch over the renter of the dwelling unit itself, but if there is a target person who needs to watch over depending on the time of day, for example, it is necessary by the detection control unit in the lighting device of the present invention. The detection may be performed by the biological information detection unit in the lighting device of the present invention only in a certain time zone, and the detection may be stopped in other time zones. Thereby, for example, the cost and electric power required for the detection by the biometric information detection unit can be reduced.
