Description

Application of Article 30, Paragraph 2 of the Patent Act Announcement by TV broadcast: Broadcast date: September 19, 2017 Broadcast program: TV Tokyo Gaia no Yoake Publisher name: TV Tokyo Corporation

The present invention relates to an illumination device, a living body movement detection system, a living body movement detection method, a program, and a recording medium.

With the aging of the population in recent years, the number of elderly people dying alone has increased, and this has become a social problem. Under these circumstances, especially for elderly people living alone, when renting a dwelling unit, there are frequent cases in which landlords who are concerned about dying alone refuse to sign a tenancy contract. On the other hand, the landlord side also has a problem that although there are many applicants, they cannot rent out the dwelling units even if they want to, and there are vacant rooms. For this reason, it is desired to take measures to prevent the elderly from dying alone and to detect crises at an early stage. This problem is not limited to the elderly, for example.

Therefore, as a method for early detection of solitary deaths of residents, for example, a system has been reported in which an abnormality detector is installed in a dwelling unit and a system is reported to a monitoring center when an abnormality is detected (Patent Document 1). .

However, installing a dedicated anomaly detector for each dwelling unit is costly and has the problem of installation space. In particular, in the case of single-person apartments, landlords own a large number of apartments, so the hurdles for introduction are high.

For convenience sake, FIG. 2 shows connection with the terminal 30 via a communication line network, as in FIG. In FIG. 2A, lighting device 10 has lighting device main body 11, and lighting device main body 11 has lighting unit 101, detection unit 102, processing unit 104, and output unit 105 to an external terminal. .

In addition, as shown in FIG. 2B, in lighting device 10, lighting device body 11 may further include a communication unit. The communication method of the communication unit is not particularly limited, and wireless communication can be mentioned, for example. Hereinafter, as shown in FIG. 2B, the wireless communication unit 103 will be described as an example of the communication unit.

The lighting device 10 includes a lighting device main body 11 and a cover member (not shown) that covers the lighting section 101 of the lighting device main body 11 and the like. That is, the lighting device main body 11 means a so-called basic structure of the lighting device, and includes, for example, a lighting section 101 including a light source, a power supply section, and the like for functioning as a lighting device. The configuration and structure of the illumination device main body 11 are not particularly limited, and as described above, it functions as an illumination device and includes the detection unit 102, the processing unit 104, the output unit 105, and optionally the wireless communication unit 103. can be further mounted. Moreover, the form of the lighting device main body 11 is not particularly limited, and examples thereof include a ceiling light that is used by being attached to a hanging ceiling attached to the ceiling, a suspended pendant light, and the like. The type of the light source of the illumination unit 101 is not particularly limited, and examples thereof include LEDs, organic ELs, and the like. In the illumination device 10, for example, the detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 are connected to a substrate on the installation side of the illumination device main body and a diffusion cover (not shown) provided on the illumination target side. ) may be accommodated between The substrate is, for example, a body substrate that fixes a light source such as an LED, a power supply circuit, etc., and the diffusion cover is, for example, a cover that diffuses light emitted from the light source to reduce glare. The power supply unit, for example, is directly or indirectly connected to an external power supply and supplies power to the lighting unit 101 , the detection unit 102 , the wireless communication unit 103 , the processing unit 104 and the output unit 105 .

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

A detection unit 102 detects biological information in a space in which the lighting device main body is installed. The type of the detection unit 102 is not particularly limited as long as it can detect biological information representing the existence of a human body. As a specific example, the detection unit 102 may be, for example, a human sensor or a camera. The detection unit 102 is preferably the human sensor, for example, because it is inexpensive and does not require complicated information processing. The human sensor is, 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 infrared sensors are attached. The human body emits infrared rays. Therefore, for example, if the human sensor detects infrared light in the space, the processing unit 104, which will be described later, can analyze the presence or absence of a living body and the movement of the living body in the space based on the detection data. In the case of a camera, if an image of the space is captured, the processing unit 104, which will be described later, can analyze the presence or absence of a living body and the movement of the living body in the space from the captured data (the detection data).

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

Based on the detection data detected by the detection unit 102, the processing unit 104 analyzes the presence or absence of the living body and the presence or absence of movement of the living body. As described above, when the detection data is the infrared detection data, for example, when infrared data in an unmanned state is set as a threshold and detection data showing a significant difference with respect to the threshold is obtained, there is no human in the space. can be determined to exist. Also, when the detection data showing a significant difference with respect to the threshold varies over time, it can be determined that the person has moved in the space. For example, the lighting device main body may further include a storage unit, and the storage unit may store information such as the threshold value as evaluation criterion information.

The processing unit 104 is, for example, a CPU. In the illuminating device 10, the processing unit 104 is preferably a small device because it is mounted, for example, on a normal illuminating device main body. Examples of the small device include a small single board computer, and a specific example thereof is Raspberry Pi (registered trademark). The CPU is connected to other units via an interface, for example.

The detection unit 102 and the processing unit 104 may be connected, for example, so that the detection data detected by the detection unit 102 is input to the processing unit 104 . As a specific example, the detection unit 102 and the processing unit 104 may be connected via an interface (I/F) or via wireless communication within the lighting device 10, for example. In the latter case, lighting device 10 preferably further includes wireless communication unit 103 .

The wireless communication unit 103 transmits detection data detected by the detection unit 102 to the processing unit 104 . The wireless communication unit 103 is not particularly limited as long as it can wirelessly connect the 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 include IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.15.1 and IEEE 802.15.4. The IEEE 802.15.1 is a standard for Bluetooth (registered trademark), for example, and the IEEE 802.15.4 is a standard for ZigBee (registered trademark), for example. Other examples include RFID, infrared communication (IrDA), and UWB.

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 is, for example, a communication module.

For example, the lighting device body 10 may further have a storage unit as described above. The storage unit can store detection data by the detection unit 102 and analysis data by the processing unit 104, for example.

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. For example, when the output unit is the display unit such as a display, the analysis data may be displayed on the display unit, and when the output unit is the audio output unit such as a speaker, the analysis Data may be emitted as sound. This allows the watcher 3 to grasp the state of the target person 2 from the external terminal 30 .

When the external terminal 30 has the display unit, the analysis data can be displayed as follows, for example. Note that this is an example and does not limit the present invention. In the following example, the smart phone is used as the external terminal 30, and the living room of the dwelling unit 1 is used as the installation location of the lighting device 10. FIG. FIG. 7 is a schematic diagram showing an example of display of analysis data on the display unit 31 of the external terminal (smartphone) 30. As shown in FIG. As shown in FIG. 7, the display unit 31 of the smartphone 30 displays the analysis result 32 and its reception time 33 in chronological order. The analysis result 32 is displayed as a message such as, for example, "Activities in the living room could not be confirmed for XX hours △△ minutes." Further, when the movement of the subject 2 is confirmed, for example, a message such as "I was able to confirm the activities in the living room for XX hours △△" is displayed. In addition, as shown in FIG. 7, the display unit 31 may also display the housing unit information and the name of the target person 2 .

(Modification 1)
The illumination 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 detection unit 102 . The detection control unit 106 is, for example, a CPU. For convenience, FIG. 3 shows connection with the terminal 30 via a communication line network, as in FIG.

By controlling the start and stop of the detection by the detection unit 102 by the detection control unit 106, for example, instead of performing continuous detection all the time, detection in a required time zone and intermittent detection are performed. Therefore, it is possible to reduce costs such as electricity bills and save the capacity of recording data. The detection control unit 106 can, for example, start detection by the detection unit 102 at arbitrary time intervals, and stop detection by the detection unit 102 when an arbitrary time has elapsed from the start of detection.

When detection data is obtained over time in the detection unit 102, the processing unit 104, for example, analyzes the presence or absence of a living body and the presence or absence of movement of the living body from the detection data received over time. By using detection data over time, for example, the subject is not in the room, the subject is in the room but not moving, the subject is moving, etc. can be analyzed in more detail.

(Modification 2)
For example, as shown in the block diagram of FIG. 4 , the lighting device 10 may have the output unit 105 as the transmission/reception unit 405 and the alert unit 107 . The transmitting/receiving unit 405 transmits information to the external terminal 30 and receives information from the external terminal 30 via the communication network 20, for example, as described above. Also, when the transmitting/receiving unit 405 receives the alert information transmitted from the terminal 30, 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 standard message, a real-time message from the watcher 3 as described later, or the like. In the lighting device 10, the wireless communication unit 103 is optional as described above.

When the watcher 3 receives analysis data, such as that the target person 2 is not moving, via the communication network 20, the watcher 3 can turn on the lighting in real time from the terminal 30 via the communication network 20. A message can be sent to the device 10 . Then, when the transmitting/receiving unit 405 of the lighting device 10 receives the message, the alerting unit 107 of the lighting device 10 can send the message to the dwelling unit 1 .

Next, the detection method of this embodiment will be described with reference to the flowchart of FIG. The detection method of this embodiment is carried out as follows using, for example, the detection system of this embodiment shown in FIG. 1 and the illumination device 10 shown in FIGS. It should be noted that the detection method of this embodiment is not limited to the use of the detection system of FIG. 1 and the illumination device 10 of FIGS.

On the other hand, the lighting device 10 illuminates the space of the room in which the lighting device 10 is installed by the lighting device main body 11 (S100).

On the other hand, the lighting device 10 detects biological information in the space of the room in which the lighting device 10 is installed by the detection unit 102 (S200). Based on the detection data, the processing unit 104 of the illumination device 10 analyzes the presence or absence of a living body in the space and the presence or absence of movement of the living body (S202). At this time, if the lighting device 10 has the wireless communication unit 103, for example, the detection data detected by the detection unit 102 of the lighting device 10 is transmitted to the processing unit 104 of the lighting device 10 (S201). 10 may receive the detection data and perform the analysis (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). The step (S200), any of the steps (S201), the steps (S202) and (S203) are repeated, for example, continuously or intermittently.

According to such a method, for example, it is possible to detect the necessity of confirming the safety of the subject living in the dwelling unit by detecting the living body movement in the dwelling unit. As a specific example, for example, in the step (202), the presence or absence of the living body and the presence or absence of movement of the living body are analyzed for changes over time, and if there is no change, the subject of the dwelling unit 1 in which the lighting device 10 is installed The result of determination that the safety of (resident) 2 needs to be confirmed can be transmitted as the analysis data to the external terminal 30 of the watcher 3 via the communication network 20 . Further, if 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 . For this reason, when the former transmission result is received, the watcher 3, for example, goes to the dwelling unit 1 and talks to the target person 2 or makes a phone call to the target person 2, so that more specific information can be obtained. Safety confirmation action can be taken. On the other hand, when the latter transmission result is received, for example, the watcher 3 can omit going to the dwelling unit 1 of the target person 2 or calling the target person 2, etc., as safety confirmation is unnecessary.

Moreover, as shown in Modified Example 2, when the lighting device 10 further has an alert unit 107, the steps shown in the flowchart of FIG. 6 can be executed. That is, when the watcher 3 receives an analysis result that seems to require confirmation of the safety of the target person 2 at the terminal 30, the watcher 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 watcher 3, a siren, a fixed message, or the like. Then, when the lighting device 10 receives the alert information by the transmission/reception unit 405 (S204), the alert is transmitted from the alert unit 107 (S205).

Thus, by enabling two-way 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 , the terminal 30 can be used to transmit a message or siren to confirm the safety of the subject 2 . Also, the alert may be, for example, an alert that notifies the occurrence of a disaster. Even if a disaster occurs around the dwelling unit, the target person 2 may not notice it. In such a case, by sending an alert to notify of the disaster, the target person 2 can be notified of the disaster and urged to evacuate, for example.

The illumination device 10 functions as illumination and detects living body movement, as described above. For example, the original function of illumination and the detection of movement of a living body may be performed in parallel, or one may be performed while the other is stopped.

For example, the lighting device 10 is normally supplied with power by turning on a main power supply (for example, a wall power supply). The detection unit 102, wireless communication unit 103, processing unit 104 and output unit 105 can be activated. However, it may be necessary to detect the subject regardless of whether the main power source is on or off. Therefore, the illumination device 10 can detect the subject regardless of whether the main power supply is ON or OFF. It is preferable to have By providing the storage battery or the battery unit in this way, for example, even when the main power supply is off, the detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 can be detected from the storage battery or the battery unit. It is possible to supply power to and activate them.

For example, even if the person watching over asks the subject to keep the main power on at all times, if the subject is an elderly person or the like, when turning off the lighting by the lighting device 10, the remote control or the like is used. , the main power may be turned off. In addition, due to disasters such as earthquakes and fires, fuses may blow and the main power supply may be turned off regardless of the subject's intention. However, if the lighting device 10 has such a form, for example, even when the main power supply is turned off, detection is possible by power supply from a backup power supply such as the power storage unit or the battery unit. , Safer and more secure monitoring is possible. In addition, in order to keep the main power source always ON, the wall power source (main power source) in the room where the lighting device of the present invention is installed may be provided with a cover for preventing ON/OFF switching.

In the present invention, the elderly, the handicapped, the sick, and the like are exemplified as the subject, but the subject is not limited to this. INDUSTRIAL APPLICABILITY The present invention can be used in a dwelling unit where a target person who is worried about being alone in the dwelling unit resides for the watcher. Specific examples of the subject include children, pets, and dementia patients with a tendency to wander. Normally, children do not live alone in a dwelling unit, but for example, children spend time alone in a dwelling unit during times when their parents are away for work, shopping, hospital visits, or the like. Even in such cases, the illumination device, detection system and detection method of the present invention are useful. In this way, for example, although it is not necessary to watch over the tenant of the dwelling unit itself, if there is a target person who needs to be watched over depending on the time period, for example, the detection control unit in the lighting device of the present invention The detection by the detection unit in the lighting device of the present invention may be performed only during certain time periods, and the detection may be stopped during other time periods. As a result, for example, the cost and power required for detection by the detection unit can be reduced.

For example, the living body movement detection method of the present embodiment further analyzes changes over time in the presence or absence of the living body and the presence or absence of movement of the living body in the above-described processing steps, and if there is no change and the door is locked, When it is analyzed that the door is unlocked or the door is opened and closed, the determination result that it is necessary to confirm the safety of the resident of the dwelling unit in which the lighting device is installed is provided as the analysis data via the communication line network. is transmitted to the external terminal, and if there is a change, the determination result that the safety confirmation of the resident is unnecessary is transmitted to the external terminal as the analysis data via the communication line network. .

An example of the illumination device of this embodiment and a detection system using the same will be described with reference to FIG. FIG. 8 is a schematic diagram showing the overall configuration when using the illumination device and the detection system. A lighting device 10 is attached to a room in a dwelling unit 1 of a subject 2 , and a magnetic detection device 40 is attached near a door 50 of the dwelling unit 1 . The illumination device 10 and the magnetic detection device 40 can communicate with each other. The communication method between the illumination device 10 and the magnetic detection device 40 is not limited as will be described later, but the wireless communication 40A will be described below as an example.

In the dwelling unit 1, the door 50 to which the magnetism detecting device 40 is attached is, for example, a room door or an entrance door, and the entrance door is particularly preferable. The installation position of the magnetic detection device 40 with respect to the door 50 is not particularly limited. In the present invention, when analyzing 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. This is the position where the magnetic change due to is detectable.

The door 50 is locked, for example, by fitting a bar of a deadbolt (final tightening) of the door 50 into a corresponding strike (receiving seat). is extracted. The locking/unlocking may be operated, for example, by a key or by a thumb-turn. The opening/closing of the door 50 is not limited to the locking/unlocking described above, but means the opening/closing of the door 50 for the entry and exit of a person.

A method for generating a magnetic change due to switching between locking and unlocking of the door 50 and a magnetic change due to opening and closing of the door 50 is not particularly limited, and a magnet can be used, for example. The magnet is preferably arranged at a position where the distance or angle with respect to the magnetic detection device 40 changes, for example, by switching between locking and unlocking of the door 50 or opening and closing the door 50 . Thus, by locking/unlocking the door 50 or opening/closing the door 50, a magnetic change can be generated. As a specific example, FIG. 9 shows a configuration in which the magnets are arranged on the thumb-turn 51 of the door 50. As shown in FIG. FIG. 9 is a schematic diagram showing the positional relationship between the thumb-turn 51 of the door 50 and the magnetic detection device 40. As shown in FIG. In FIG. 9, a magnet 52 is fixed to the thumbturn 51 . As shown in FIG. 9, for example, in the locked state of (A), the thumb-turn 51 is horizontal, and in the unlocked state of (B), the thumb-turn 51 is vertical. The magnet 52 fixed to the thumb-turn 51 has a different distance from the magnetic detector 40 between the locked state (A) and the unlocked state (B). Therefore, the magnetism detection device 40 can detect a magnetism change caused by switching between locking and unlocking by the thumb-turn 51 .

Moreover, it 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 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 magnetism detection device 40 can detect magnetism changes due to the opening and closing of the door 50 .

As described above, the communication method between the illumination device 10 and the magnetic detection device 40 is not particularly limited, and wireless communication may be used, for example.

The power supply unit, for example, is directly or indirectly connected to an external power supply and supplies power to the illumination unit 101 , biological information detection unit 102 , wireless communication unit 103 , processing unit 104 and output unit 105 .

In addition, when illumination is unnecessary, such as in the daytime, the biological information detection unit 102, the wireless communication unit 103, and the processing unit 104 can be operated while the illumination unit 101 is turned off by, for example, installing an automatic lighting device. , the output unit 105 can be operated.

In the illumination 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 . The wireless communication unit 103 receives the magnetic detection data transmitted from the magnetic detection device 40 and transmits the data to the processing unit 104 .

In the illumination device 10, biometric information detection data detected by the biometric information detection unit 102 is sent to the processing unit 104 and analyzed as described later. Communication between the biological information detection unit 102 and the processing unit 104 is not particularly limited, and may be, for example, inter-circuit communication via a bus or wireless communication via a wireless communication unit. In the latter case, the wireless communication section 103 can be used as the wireless communication section. The wireless communication unit 103 can wirelessly communicate with the processing unit 104 in the same lighting device 10 . The wireless communication unit 103 then 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 the biological information detection unit 102 and the processing unit 104 mounted in the same lighting device 10 .

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 in addition to the biometric information detection data. As described above, for example, by arranging the magnetism detecting device 40 and the magnet near the door 50, a magnetic change can be generated by switching between locking and unlocking the door 50 or opening and closing the door 50. can be done. For this reason, for example, a magnetic change due to switching between locking and unlocking of the door 50 or a magnetic change due to opening and closing of the door 50 is set as evaluation criterion information, and the magnetic detection data is compared with the evaluation criterion information. , whether the door 50 is locked or unlocked, or whether the door 50 is open or closed. The storage unit may store, as the evaluation criterion information, 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.

The illumination 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, analysis data by the processing unit 104, and the like.

When the external terminal 30 has the display unit, the analysis data can be displayed as follows, for example. Note that this is an example and does not limit the present invention. In the following example, the smart phone is used as the external terminal 30, and the living room of the dwelling unit 1 is used as the installation location of the lighting device 10. FIG. FIG. 15 is a schematic diagram showing an example of display of analysis data on the display unit 31 of the external terminal (smartphone) 30. As shown in FIG. As shown in FIG. 15, the display unit 31 of the smartphone 30 displays the analysis result 32 and the reception time 33 in chronological order. The analysis result 32 is displayed as a message such as, for example, "Activities in the living room could not be confirmed for XX hours" or "Unlocking of the front door could not be confirmed for XX minutes." be done. In addition, if it is confirmed that Subject 2 has moved, for example, "I was able to confirm the activity in the living room for XX hours △△", and if it is confirmed that the front door is unlocked, for example, A message such as "I was able to confirm that the entrance door was unlocked for XX hours XX minutes" is displayed. In addition, as shown in FIG. 15, the display unit 31 may also display the housing unit information and the name of the target person 2 .

The magnetic detection device 40 is, for example, a device installed near the door 50 of the dwelling unit 1, as shown in FIG. 8, and has a magnetic sensor 401 and a wireless communication unit 402 as an example of a communication unit.

The magnetic sensor 401 is a sensor that detects magnetism, and in the present invention detects, for example, 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 capable of communicating with the lighting device 10, and for example, the wireless communication unit 402 can be exemplified as described above. The wireless communication unit 402 can wirelessly communicate with the lighting device 10, and the wireless communication method is not particularly limited and is the same as described above.

(Modification 1)
For example, the lighting device 10 may further include a detection control unit 106 as shown in the block diagram of FIG. 11 and like the first modification of the first embodiment.

(Modification 2)

When the watcher 3 receives analysis data via the communication network 20 that the target person 2 has not moved, the door 50 has not been unlocked for a long time, the door 50 has not been opened for a long time, etc. The watcher 3 can send a message to the lighting device 10 in real time from the terminal 30 via the communication network 20 . Then, when the transmitting/receiving unit 405 of the lighting device 10 receives the message, the alerting unit 107 of the lighting device 10 can send the message to the dwelling unit 1 .

Next, the detection method of this embodiment will be described with reference to the flowchart of FIG. The detection method of this embodiment is carried out as follows using, for example, the detection system of this embodiment shown in FIG. 8 and the illumination device 10 shown in FIGS. In the flowchart of FIG. 13 , the steps (S300, S301) surrounded by thick lines indicate the steps performed by the magnetic detection device 40, and the others indicate the steps performed by the illumination device 10. In FIG. It should be noted that the detection method of this embodiment is not limited to the use of the detection system of FIG. 8 and the illumination device 10 of FIGS. Illumination, biometric information detection, and magnetic change detection will be described in order, but as will be described later, the order of these is not limited.

As in the first embodiment, the illumination device 10 illuminates a space (S100), detects biological information (S200), transmits the detected biological information detection data (S201), detects the presence or absence of a living body in the space, and detects the living body. is analyzed (S202), and the obtained analysis data 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 sensor 401 of the magnetic detector 40 detects a magnetic change caused by locking and unlocking the door of the dwelling unit 1 or a magnetic change caused by opening and closing the door (S300). The detected magnetic detection information is transmitted from the detection device 40 to the processing unit 104 of the illumination device 10 (S301). Then, the illumination device 10 receives the magnetism detection information transmitted from the magnetism detection device 40 through the wireless communication unit 103 and transmits the magnetism detection information to the processing unit 104 of the illumination device 10 . Next, when receiving the magnetism detection information, the processing unit 104 of the lighting device 10 analyzes whether the door 50 is locked/unlocked or whether the door 50 is opened or closed based on the received magnetism 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 step (S300) to step (S302) and step (S203) are repeated, for example, continuously or intermittently.

In the present embodiment, the step (S100) related to illumination, the steps (S200) to (S202) related to biological information, the steps (S300) to (S302) related to magnetic change, and the step (S203) are performed in parallel, for example. It can be carried out. Also, the step (S100) related to illumination is optional, and other steps may be performed while this step (S100) is not performed. In other words, for the illumination device 10, other processes may be performed regardless of whether the illumination is ON/OFF.

According to such a method, first, as a first form, as described in the first embodiment, for example, by detecting the movement of a living body in the dwelling unit, the necessity of confirming the safety of the subject living in the dwelling unit is determined. detectable. As a specific example, for example, in the step (S202), the presence or absence of the living body and the presence or absence of movement of the living body are analyzed for changes over time. The result of determination that the safety of (resident) 2 needs to be confirmed can be transmitted as the analysis data to the external terminal 30 of the watcher 3 via the communication network 20 . Further, if 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 . For this reason, when the former transmission result is received, the watcher 3, for example, goes to the dwelling unit 1 and talks to the target person 2 or makes a phone call to the target person 2, so that more specific information can be obtained. Safety confirmation action can be taken. On the other hand, when the latter transmission result is received, the watcher 3 can omit going to the residence 1 of the target person 2 or calling the target person 2, for example, as the safety confirmation is unnecessary.

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, the safety of the subject living in the dwelling unit can be confirmed from a viewpoint different from that of the first form. can detect the necessity of As a specific example, for example, in the step (S302), the locking/unlocking of the door or the opening/closing of the door is analyzed, and if there is no change in the locking/unlocking of the door for a long period of time, or if there is no change in the opening/closing of the door. transmits the result of determination that it is necessary to confirm the safety of the target person (resident) 2 in the dwelling unit 1 in which the lighting device 10 is installed as the analysis data to the outside of the watcher 3 via the communication network 20. It can be transmitted to the terminal 30. Further, if 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 . For this reason, when the former transmission result is received, the watcher 3, for example, goes to the dwelling unit 1 and talks to the target person 2 or makes a phone call to the target person 2, so that more specific information can be obtained. Safety confirmation action can be taken. On the other hand, when the latter transmission result is received, the watcher 3 can omit going to the residence 1 of the target person 2 or calling the target person 2, for example, as the safety confirmation is unnecessary.

Moreover, the following judgment is also possible from the combination of said 1st form and said 2nd form. That is, for example, in the step (S202), there is no change over time in the presence or absence of the living body and the presence or absence of movement of the living body, and in the step (S302), it is analyzed that the door is locked and unlocked or the door is opened and closed. In this case, the determination result that the subject's safety confirmation is necessary may be transmitted as the analysis data to the external terminal via the communication line 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 occur. On the other hand, in the step (S202), if there is a change over time in the presence or absence of the living body and the presence or absence of movement of the living body, the judgment result that the subject's safety confirmation is unnecessary is used as the analysis data. It may be transmitted to the external terminal via a communication line network. This is because it can be determined that the subject is able to move. In addition, if the movement of a living body is detected in the dwelling unit, then it is locked, and after that the movement within 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. becomes lower.

Moreover, as shown in Modification 2, when the lighting device 10 further has an alert unit 107, the steps shown in the flowchart of FIG. 14 can be executed. That is, when the watcher 3 receives an analysis result that seems to require confirmation of the safety of the target person 2 at the terminal 30, the watcher 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 from the watcher 3, a siren, a fixed message, or the like. Then, when the lighting device 10 receives the alert information by the transmission/reception unit 405 (S204), the alert is transmitted from the alert unit 107 (S205).

Thus, by enabling two-way 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 , the terminal 30 can be used to transmit a message or siren to confirm the safety of the subject 2 . Also, the alert may be, for example, an alert that notifies the occurrence of a disaster. Even if a disaster occurs around the dwelling unit, the target person 2 may not notice it. In such a case, by sending an alert to notify of the disaster, the target person 2 can be notified of the disaster and urged to evacuate, for example.

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