Description

Technical Field

[0001] The present invention relates to a lighting device, a living body movement detection system, a living body movement detection method, a program, and a recording medium.

Background Art

[0002] With the recent aging of society, the number of elderly people who die alone has been increasing, becoming a social problem. In light of this situation, especially in the case of elderly people living alone, when renting a dwelling unit, there are frequent cases where the landlord refuses to conclude a tenancy agreement due to concerns about the tenant dying alone. On the other hand, even though there are many people wishing to rent, the landlord may not be able to rent out the dwelling unit, resulting in vacant rooms. Therefore, measures are desired to prevent the elderly from dying alone and to detect crises at an early stage. This problem is the same for, for example, not only the elderly but also, for example, disabled people living alone, bedridden patients, etc.

[0003] Therefore, as a method for early detection of cases such as the elderly dying alone, for example, a system has been reported in which an abnormality detector is installed in a dwelling unit and a notification is sent to a monitoring center when an abnormality is detected (Patent Document 1).

[0004] However, installing a dedicated abnormality detector for each dwelling unit is costly and also poses a problem of installation space. Especially in the case of apartments for single-person households, since the landlord owns a large number of units, the hurdle for introduction is high.

Modes for Carrying Out the Invention

[0014] As described above, the present invention is useful for detecting the safety of a resident who may be immobile within a dwelling, such as an elderly person, a disabled person, or a patient, when detected by an external person. The living body movement detection system and the living body movement detection method of the present invention can be implemented, for example, by installing the lighting device of the present invention as a lighting device in the dwelling of the target person, and a third party (hereinafter referred to as a caregiver) who wants to know the state of the target person owns an external terminal. The caregiver is, for example, the homeowner of the dwelling, a family member of the target person, a caregiver, a nurse, or the like. According to the present invention, for example, it is possible to detect whether the target person is inside the dwelling, whether the target person is moving inside the dwelling, locking / unlocking of the door, and opening / closing of the door. Therefore, when the caregiver receives analysis data indicating that, for example, the target person has been absent for a long time, the target person has not been moving for a long time, the door of the target person's dwelling has not been unlocked for a long time, or the door of the target person's dwelling has not been opened or closed for a long time, the caregiver can visit the dwelling of the target person and call out, or call the target person. Therefore, the caregiver can take actions with respect to the target person based on the real-time analysis data received via the present invention. The lighting device of the present invention can also be said to be a lighting device for detecting living body movement that also serves as living body movement detection.

[0015] Next, the lighting device, the living body movement detection system (hereinafter referred to as the detection system), and the living body movement detection method (hereinafter referred to as the detection method) of the present invention will be described with reference to the drawings and by way of example. The present invention is not limited or restricted in any way by the following embodiments. The descriptions in each embodiment can be mutually incorporated.

[0016] (Embodiment 1) An example of the lighting device of the present embodiment and a detection system using the same will be described with reference to FIG. 1. FIG. 1 is a schematic diagram showing the overall configuration when using the lighting device and the detection system. 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 near the door 50 of the dwelling unit 1. On the other hand, the caregiver 3 who wants to know the state of the subject 2 carries the terminal 30. The lighting device 10 and the terminal 30 can be connected via a communication line 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 will be described later, but hereinafter, wireless communication 40A will be taken as an example for explanation.

[0017] In the dwelling unit 1, the room where the lighting device 10 is attached is not particularly limited. Generally, the dwelling unit 1 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, analysis data indicating whether the subject 2 is in the dwelling unit 1 or is moving within the dwelling unit 1 can be obtained. Therefore, the lighting device 10 may be attached, for example, to all rooms, or to the rooms where the subject spends a long time (for example, the living room, the bedroom, etc.).

[0018] The lighting device 10 is, for example, for ceiling installation or wall installation, and ceiling installation is preferred. By installing the lighting device 10 on the ceiling, for example, it is possible to detect biometric information over a wider range.

[0019] 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 among them, the entrance door is preferred. The installation location of the magnetic detection device 40 with respect to the door 50 is not particularly limited. In the present invention, when analyzing the locking and unlocking of the door 50, for example, it is a position where a magnetic change due to the switching between locking and unlocking can be detected, and when analyzing the opening and closing of the door 50, for example, it is a position where a magnetic change due to the switching of the opening and closing of the door 50 can be detected.

[0020] The locking of the door 50 is performed, for example, by fitting the bolt (main lock) of the deadbolt of the door 50 into the corresponding strike (receptacle), and the unlocking of the door 50 is performed by pulling out the deadbolt from the strike. The locking and unlocking may be operated, for example, by a key or by a thumb turn. The opening and closing of the door 50 is not limited to the above locking and unlocking, and also means the opening and closing of the door 50 for people to enter and exit.

[0021] The method of generating magnetic changes by switching between locking and unlocking of the door 50 and magnetic changes by switching between opening and closing of the door 50 is not particularly limited, and for example, a magnet can be used. The magnet is preferably arranged, for example, at a position where the distance or angle with respect to the magnetic detection device 40 changes due to the switching between locking and unlocking of the door 50 or the opening and closing of the door 50. Thereby, magnetic changes can be generated by locking and unlocking the door 50 or opening and 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 diagram 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. And the magnet 52 fixed to the thumb turn 51 has a changed distance with respect to the magnetic detection device 40 between the locked state of (A) and the unlocked state of (B). Therefore, the magnetic detection device 40 can detect magnetic changes due to the switching between locking and unlocking by the thumb turn 51.

[0022] Moreover, it is not limited to this. 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 moves away from the door 50 frame, and when the door 50 is closed, the magnet 52 moves closer to the door 50 frame. Therefore, the magnetic detection device 40 can detect magnetic changes due to the opening and closing of the door 50.

[0023] As described above, the communication method between the lighting device 10 and the magnetic detection device 40 is not particularly limited, and for example, wireless communication 40A can be cited. 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.

[0024] As the communication network 20 connecting the lighting device 10 and the terminal 30, for example, a known communication network can be used. The communication method is not particularly limited, and for example, it may be wired or wireless. Specifically, for example, an Internet line, a telephone line, etc. can be cited.

[0025] The terminal 30 only needs to be connectable to the lighting device 10 via the communication network 20. For example, it has a communication module. Further, the terminal 30 has, for example, a CPU (Central Processing Unit), an output unit, an input unit, a storage unit, etc., and may be connected by an interface (I / F) respectively. The output unit is, for example, a display unit such as a display, an audio output unit, etc. The terminal 30 is not particularly limited, and for example, a portable terminal can be cited. Specific examples of the portable terminal include a smartphone, a tablet, a mobile phone, and a wearable device. Examples of the wearable device include a wristwatch type, a glasses type, a ring type, a shoe type, a pocket type, a pendant type, etc.

[0026] Next, an example of the lighting device 10 of this embodiment will be described with reference to FIG. 3. FIG. 3 is a block diagram showing an example of the lighting device 10. In FIG. 3, for convenience, as in FIG. 1, the connection via the communication network with the terminal 30 and the connection by wireless communication with the magnetic detection device 40 are shown. The lighting device 10 has a lighting device main body 11. The lighting device main body 11 has a lighting unit 101, and further has 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.

[0027] 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 etc. of the lighting device main body 11. That is, the lighting device main body 11 means the basic structure of the lighting device. For example, it includes a lighting unit 101 containing a light source, a power supply unit, etc. for functioning as a lighting device. The configuration and structure of the lighting device main body 11 are not particularly limited. As described above, it may further be equipped with a biological information detection unit 102, a wireless communication unit 103, a processing unit 104, and an output unit 105 as long as it functions as a lighting device. Also, the form of the lighting device main body 11 is not particularly limited. For example, there are a ceiling-mounted ceiling light attached to a hanging ceiling, a pendant, etc. The type of the light source of the lighting unit 101 is not particularly limited. For example, LED, organic EL, etc. can be mentioned. 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 may be housed between the installation-side substrate in the lighting device main body and a diffusion cover (not shown) provided on the light irradiation side. The substrate is, for example, a main body substrate that fixes a light source such as an LED, a power supply circuit, etc. The diffusion cover is, for example, a cover that diffuses the light emitted from the light source and reduces glare. The power supply unit is connected to an external power supply directly or indirectly, and supplies 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.

[0028] Also, when lighting is not required, such as during the day, by installing, for example, an automatic lighting device, the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 can be operated while the lighting unit 101 is turned off.

[0029] 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 presence of a human body. As a specific example, the biological information detection unit 102 may be, for example, a human presence sensor or a camera. The biological information detection unit 102 is preferably the human presence sensor, for example, because it is inexpensive and does not require complex information processing. The human presence sensor is, for example, a pyroelectric sensor or an infrared sensor, and the infrared sensor may be, for example, an array type with a plurality of them mounted. A human body emits infrared rays. Therefore, for example, if the human presence sensor detects infrared rays in the space, the presence or absence of a living body and the movement of the living body in the space can be analyzed in the processing unit 104 described later from the biological information detection data. Also, 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 in the processing unit 104 described later from the captured data (the biological information detection data).

[0030] As described above, the lighting device 10 is preferably installed on the ceiling, for example, but it may also be on a wall or under the floor. The biological information detection unit 102 mounted on the lighting device 10 can detect biological information within the region 4 surrounded by the dotted circle in FIG. 1, for example. The region 4 is hereinafter also referred to as the detection region 4. The size of the detection region 4 is not particularly limited, and can be appropriately set according to, for example, the type and number of the biological information detection units 102 mounted on the lighting device 10, the height of the ceiling where the lighting device 10 is installed, the size of the room, etc. The detection region 4 by one lighting device 10 can assume, for example, 1K from a general floor plan for a single elderly person.

[0031] 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 communicate wirelessly 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.

[0032] 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 will be described later. The communication between the biometric information detection unit 102 and the processing unit 104 is not particularly limited. For example, it may be 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 perform wireless communication with the processing unit 104 within 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 within the same lighting device 10.

[0033] The wireless communication method of the wireless communication unit 103 is not particularly limited. For example, IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.15.1, IEEE 802.15.4, etc. can be mentioned. The IEEE 802.15.1 is, for example, a standard related to Bluetooth (registered trademark), and the IEEE 802.15.4 is, for example, a standard related to ZigBee (registered trademark). In addition, for example, RFID, infrared communication (IrDA), and UWB can be mentioned.

[0034] The processing unit 104 analyzes the presence or absence of a living body and the presence or absence of movement of the living body based on the biometric information detection data. As described above, when the biometric information detection data is the detection data of the infrared rays, for example, when the infrared data in a state without a person is used as a threshold value and detection data showing a significant difference from the threshold value is obtained, it can be determined that a person exists in the space. Also, when the detection data showing a significant difference from the threshold value changes over time, it can be determined that a 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 the threshold value as evaluation reference information.

[0035] 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 near the door 50, a magnetic change can be generated by switching the locking and unlocking of the door 50 or by opening and closing the door 50. Therefore, for example, a magnetic change caused by switching the locking and unlocking of the door 50 or a magnetic change caused by opening and closing the door 50 is set as evaluation criterion information, and by comparing the magnetic detection data with the evaluation criterion information, it is possible to determine the locking and unlocking of the door 50 or the opening and closing of the door 50. The storage unit may store the relationship between the switching of the locking and unlocking of the door 50 and the magnetic change and the relationship between the opening and closing of the door 50 and the magnetic change as the evaluation criterion information.

[0036] The processing unit 104 may be, for example, a CPU. In the lighting device 10, since the processing unit 104 is mounted on a normal lighting device main body, for example, it is preferably a small device. Examples of the small device include a small single-board computer, and specific examples include Raspberry Pi (registered trademark), etc. The CPU is connected to other parts via an interface, for example.

[0037] 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 transceiver 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.

[0038] The lighting device main body 11 may further have a storage unit, for example. 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, and analysis data by the processing unit 104, etc.

[0039] 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 the output unit, for example. When the output unit is the display unit such as a display, the analysis data may be displayed on the display unit, or when the output unit is the audio output unit such as a speaker, the analysis data may be emitted as sound. Thus, the caregiver 3 can grasp the state of the target person 2 from the external terminal 30.

[0040] When the external terminal 30 has the display unit, for example, the analysis data can be displayed as follows. Note that this is an example and does not limit the present invention. The following example will be described by taking a smartphone as the external terminal 30 and the living room of the residential house 1 as the installation location of the lighting device 10. FIG. 8 is a schematic diagram showing an example of the display of the analysis data on the display unit 31 of the external terminal (smartphone) 30. As shown in FIG. 8, on the display unit 31 of the smartphone 30, the analysis result 32 and its reception time 33 are displayed in time series. The analysis result 32 is displayed as a message such as "The activity in the living room could not be confirmed at XX:XX", "The unlocking of the front door could not be confirmed at XX:XX", for example. When the movement of the target person 2 is confirmed, for example, a message such as "The activity in the living room could be confirmed at XX:XX" or when the unlocking of the front door is confirmed, for example, "The unlocking of the front door could be confirmed at XX:XX" is displayed. Also, on the display unit 31, the residential house information and name of the target person 2 may be displayed as shown in FIG. 8.

[0041] The magnetic detection device 40 is a device installed near the door 50 of the residential house 1 as shown in FIG. 1, for example, and has a magnetic sensor 401 and a wireless communication unit 402 as an example of the communication unit.

[0042] The magnetic sensor 401 is a sensor that detects magnetism. In the present invention, for example, it detects a magnetic change caused by locking and unlocking of the door 50, or a magnetic change caused by opening and closing of the door 50. As the magnetic sensor 401, for example, a Hall element or the like can be used.

[0043] The communication unit only needs to be able to communicate with the lighting device 10. For example, as described above, the wireless communication unit 402 can be exemplified. The wireless communication unit 402 can communicate with the lighting device 10 wirelessly, and the wireless communication method is not particularly limited and is the same as described above.

[0044] (Modification Example 1) The lighting device 10 may further include a detection control unit 106, for example, as shown in the block diagram of FIG. 4. The detection control unit 106 controls the start and stop of the detection by the biological information detection unit 102. The detection control unit 106 is, for example, a CPU. In FIG. 4, for convenience, similar to FIG. 3, connections via a communication line network with the terminal 30 and connections by wireless communication with the magnetic detection device 40 are shown.

[0045] By controlling the start and stop of the detection by the biological information detection unit 102 by the detection control unit 106, for example, continuous detection is not always performed, but detection in a necessary time zone and intermittent detection can be performed, and costs such as electricity charges can be reduced, and the capacity of recorded data can be saved. 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 at an arbitrary time after the start of the detection.

[0046] 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 biological 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 not moving, that the subject is moving, etc.

[0047] (Modification Example 2) For example, as shown in the block diagram of FIG. 5, in the lighting device 10, the output unit 105 may be the transmission / reception unit 405, and further, may include an alert unit 107. As described above, the transmission / reception unit 405 transmits information to the external terminal 30 and receives information from the external terminal 30 via, for example, the communication line network 20. Further, when the alert unit 107 receives the alert information transmitted from the terminal 30 by the transmission / reception unit 405, the alert unit 107 issues an alert. The alert unit 107 is, for example, a speaker, and the alert is, for example, a siren, a fixed message, a real-time message of the caregiver 3 as described later, or the like.

[0048] When the caregiver 3 receives analysis data such as that the subject 2 is not moving, the door 50 has not been unlocked for a long time, or the door 50 has not been opened for a long time via the communication line network 20, the caregiver 3 can send a message to the lighting device 10 in real time from the terminal 30 via the communication line network 20. Then, when the transmission / reception unit 405 of the lighting device 10 receives the message, the message can be relayed to the living unit 1 from the alert unit 107 of the lighting device 10.

[0049] Next, the detection method of the present embodiment will be described with reference to the flowchart of FIG. 6. The detection method of the present embodiment is implemented as follows using, for example, 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 (S300, S301) surrounded by thick lines indicate the steps executed by the magnetic detection device 40, and the other steps indicate the steps executed by the lighting device 10. Note that 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. Lighting, detection of biological information, and detection of magnetic changes will be described in order, but as described later, these orders are not limited.

[0050] The lighting device 10 illuminates the space of the room in which the lighting device 10 is installed by the lighting device main body (S100).

[0051] In addition, the lighting device 10 detects biometric information in the space of the room where the lighting device 10 is installed by the biometric information detection unit 102 (S200). Then, the wireless communication unit 103 of the lighting device 10 transmits the detected biometric information detection data to the processing unit 104 of the lighting device 10 (S201), and the processing unit 104 receives it. Next, the processing unit 104 of the lighting device 10 analyzes the presence or absence of a living body and the presence or absence of movement of the living body in the space based on the received biometric 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 process from step (S200) to step (S203) is repeated continuously or intermittently, for example.

[0052] On the other hand, the magnetic detection device 40 detects a magnetic change due to locking and unlocking of the door of the dwelling unit 1 or a magnetic change due to opening and closing of the door by the magnetic sensor 401 (S300), and the wireless communication unit 402 transmits the detected magnetic detection information from the magnetic 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 its wireless communication unit 103 and transmits it 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, it 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). This process from step (S300) to step (S302) and step (S203) is repeated continuously or intermittently, for example.

[0053] In this embodiment, the process related to lighting (S100), the processes related to biological information (S200) to (S202), the processes related to magnetic changes (S300) to (S302), and the process (S203) can be performed in parallel, for example. Also, the process related to lighting (S100) is optional, and other processes may be performed without performing this process (S100). That is, for the lighting device 10, other processes may be performed regardless of the ON / OFF of the lighting.

[0054] According to such a method, first, as a first form, for example, by detecting the movement of a living body in a dwelling unit, it is possible to detect the necessity of confirming the safety of the subject living in the dwelling unit. As a specific example, for example, in the step (S202), regarding the presence or absence of a living body and the presence or absence of movement of the living body, an analysis is made of the temporal change. If there is no change, a determination result that it is necessary to confirm the safety of the subject (resident) 2 of the dwelling unit 1 where the lighting device 10 is installed can be transmitted as the analysis data to the external terminal 30 of the caregiver 3 via the communication network 20. Also, if there is a change, a determination result that it is not necessary to confirm the safety of the subject 2 can be transmitted as the analysis data to the external terminal 30 of the caregiver 3 via the communication network 20. Therefore, when receiving the former transmission result, the caregiver 3 can, for example, go to the dwelling unit 1, call out to the subject 2, or call the subject 2 on the phone, and further take specific actions to confirm the safety. On the other hand, when receiving the latter transmission result, the caregiver 3 can, for example, omit going to the dwelling unit 1 of the subject 2 or calling the subject 2 on the phone, etc., considering that the safety confirmation is not necessary.

[0055] Furthermore, according to the method, as a second form, for example, by detecting the locking / unlocking of the door or the opening / closing of the door, it is possible to detect the necessity of confirming the safety of the person living in the dwelling unit from a perspective different from the first form. As a specific example, for instance, in the step (S302), the locking / unlocking of the door or the opening / closing of the door is analyzed. When there is no change in the locking / unlocking of the door or no change in the opening / closing of the door over a long period of time, a judgment result that it is necessary to confirm the safety of the person (resident) 2 in the dwelling unit 1 where the lighting device 10 is installed can be transmitted as the analysis data to the external terminal 30 of the caregiver 3 via the communication network 20. Also, when there is a change, a judgment result that it is not necessary to confirm the safety of the person 2 can be transmitted as the analysis data to the external terminal 30 of the caregiver 3 via the communication network 20. Therefore, when receiving the former transmission result, the caregiver 3 can, for example, go to the dwelling unit 1, call out to the person 2, or call the person 2 on the phone to take further specific actions to confirm the safety. On the other hand, when receiving the latter transmission result, the caregiver 3 can, for example, omit going to the dwelling unit 1 of the person 2 or calling the person 2 on the phone, etc., considering that the safety confirmation is not required.

[0056] In addition, the following judgment is also possible from the combination of the first form and the second form. That is, for example, in the step (S202), if there is no change over time in the presence or absence of a living body and the movement of the living body, and in the step (S302), it is analyzed that there is door locking and unlocking or door opening and closing, a judgment result that the safety confirmation of the subject is necessary may be transmitted as the analysis data to the external terminal via the communication network. This is because, even though there is no change in the living body, if there is a change in door locking / unlocking or opening / closing, for example, the intrusion of a suspicious person may be considered. On the other hand, if there is a change over time in the presence or absence of a living body and the movement of the living body in the step (S202), a judgment result that the safety confirmation of the subject is unnecessary may be transmitted as the analysis data to the external terminal via the communication network. This is because it can be determined that the subject is able to move. Also, when the movement of a living body is detected inside the dwelling unit, then locking occurs, and then the movement inside the dwelling unit is not detected for a long time afterwards, the possibility of going out or traveling is high, so the necessity of safety confirmation is reduced.

[0057] Also, as shown in Modification Example 2, when the lighting device 10 further has an alert unit 107, the steps as shown in the flowchart of FIG. 7 can be executed. That is, when the caregiver 3 receives an analysis result that safety confirmation of the subject 2 is considered necessary at the terminal 30, the caregiver 3 uses the terminal 30 to transmit alert information to the lighting device 10. The alert information is, for example, a real-time voice message of the caregiver 3, a siren, a fixed message, etc. Then, when the lighting device 10 receives the alert information by the transceiver unit 405 (S204), the alert is transmitted from the alert unit 107 (S205).

[0058] In this way, by enabling two-way information communication between the lighting device 10 installed in the household 1 of the target person 2 and the terminal 30 carried by the caregiver 3, for example, the caregiver 3 can use the terminal 30 to send a message or siren to confirm the safety of the target person 2. Further, the alert may be, for example, an alert for notifying the occurrence of a disaster. Even when a disaster occurs near the household, the target person 2 may not notice it. In such a case, by sending an alert for notifying the disaster, it is possible to notify the target person 2 of the disaster and prompt evacuation, for example.

[0059] 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 the movement of a living body, and the locking / unlocking or opening / closing of a door may be performed in parallel, for example, or one of them may be executed while the other is stopped.

[0060] For example, the lighting device 10 is usually powered by turning on the main power supply (for example, wall power supply). Therefore, regardless of whether the lighting unit 101 of the lighting device main body is activated or not, 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, regardless of whether the main power supply is on or off, it may be necessary to detect the target person. For this reason, since the lighting device 10 can detect the target person regardless of whether the main power supply is on or off, for example, it is preferable that the lighting device main body further includes at least one of a power storage unit and a battery unit. In this way, by providing the storage battery or the battery unit, for example, even when the main power supply is off, power can be supplied from the storage battery or the battery unit to the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 to activate them.

[0061] Even if the caregiver requests the subject person to keep the main power supply on at all times, for example, when the subject person is an elderly person or the like, when turning off the lighting by the lighting device 10, instead of using a remote control or the like, the main power supply may be turned off. Also, due to disasters such as earthquakes and fires, the fuse may blow and the main power supply may be turned off regardless of the intention of the subject person. However, if the lighting device 10 is in such a form, for example, even when the main power supply is turned off, detection becomes possible by power supply from a backup power source such as the power storage unit or the battery unit, and more secure and reassuring monitoring becomes possible. In addition, in order to keep the main power supply on at all times, 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.

[0062] In the present invention, although the elderly, disabled persons, and patients are exemplified as the subject person, it is not limited thereto. The present invention can be used by the caregiver in a dwelling unit where a subject person who is worried about being alone in the dwelling unit resides. Specific examples of the subject person include, for example, children, pets, and dementia patients with a wandering habit. Usually, children do not live alone in a dwelling unit, but for example, during the time when the parent is absent due to work, shopping, hospital visits, etc., the child is spending time alone in the dwelling unit. Even in such a case, the lighting device, detection system, and detection method of the present invention are useful. Also, in this way, for example, there is no need to monitor the tenant of the dwelling unit itself, but when there is a subject person who needs to be monitored depending on the time zone, for example, by the detection control unit in the lighting device of the present invention, detection by the biological information detection unit in the lighting device of the present invention may be performed only during the necessary time zone, and detection may be stopped during other time zones. Thereby, for example, the cost and power consumption associated with detection by the biological information detection unit can be reduced.

[0063] [Embodiment 2] The program of this embodiment is a program that can execute the detection method of the above embodiment on a computer. By installing and executing the program of this embodiment on a computer, for example, the detection method of the present invention can be realized. In this case, the CPU of the computer functions as, for example, the processing unit and optionally as the detection control unit. Further, the program of this embodiment may be recorded, for example, in a storage device such as a computer-readable recording medium. The recording medium is not particularly limited, and examples thereof include a read-only memory (ROM), a hard disk (HD), an optical disk, and a floppy (registered trademark) disk (FD).

[0064] As described above, the present invention has been described with reference to the embodiments. However, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

Industrial Applicability

[0065] According to the present invention, for example, by simply replacing the lighting device that is essential for a residential unit, while performing the normal lighting function, it is possible to detect the movement of a living body and the locking / unlocking or opening / closing of a door, and output the result to a person outside the residential unit. Therefore, for example, even if the occupant is an elderly person living alone, the external homeowner can easily know whether the occupant is present or moving, etc., which enables prevention and early detection of solitary death.
