[0002] Those who care for them have a need to know not only the current state of the person they are watching over, but also what the person was like before reaching that state. In particular, if the person being watched over has been out or has just returned home, knowing this allows the person being watched over to be watched over more appropriately. However, with conventional technology, it is difficult to tell at a glance whether the person being watched over has gone out or has just returned home (see Patent Document 1).

[0003] With the aim of enabling the watcher to easily recognize past changes in the presence or absence status of the person being watched, Patent Document 1 discloses a monitoring system for watching over a person being watched over who uses a managed area, which comprises a display means for displaying first display information indicating the current status of the person being watched over, including at least presence or absence, and a storage means for storing a history of changes in the presence or absence of the person being watched over, and which is characterized in that when the change history indicates that the presence or absence of the person being watched over has changed within a predetermined period of time in the past, the display means displays second display information indicating that there has been a change in the presence or absence status of the person being watched over.

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a mode for carrying out the present invention (hereinafter referred to as an "embodiment") will be described in detail with reference to the accompanying drawings. It should be noted that the same elements are denoted by the same numbers or symbols throughout the description of the embodiments.

[0025] [First embodiment] A management system A (hereinafter, sometimes simply referred to as "management system A") that manages biometric information transmitted by broadcast communication in a first embodiment of the present invention will be described with reference to Figures 1 to 8.

[0026] FIG. 1 is a diagram for explaining a management system A according to a first embodiment of the present invention. As shown in Figure 1, the management system A includes a wearable terminal 1, a light bulb 2 which serves as a relay device, a server 3, and a reception-permitted terminal 4, and the light bulb 2 and the server 3, and the reception-permitted terminal 4 and the server 3 are capable of communicating via a network N. Furthermore, as will be described later, short-range communication is possible between the wearable device 1 and the light bulb 2.

[0027] (Wearable device 1) FIG. 2 is a diagram illustrating the configuration of the wearable device 1 according to the first embodiment of the present invention. The wearable terminal 1 is a terminal worn by a user registered in the management system A, and as shown in Figure 2, it comprises a CPU 11, a RAM 12, a ROM 13, a biometric information acquisition unit 14, a first short-range wireless communication unit 15, and a power generation unit 16, which are connected so as to be accessible via a bus 17. A user who wears and uses the wearable device 1 will hereinafter also be referred to as a wearer. Moreover, instead of the CPU 11, the RAM 12, and the ROM 13, an integrated circuit or the like may be used.

[0028] The CPU 11 is a central processing unit that loads a program stored in the ROM 13 into the RAM 12 and controls various controls and arithmetic processes in accordance with the program. For example, the biometric information acquisition unit 14 (described later) performs calculations on biometric information that needs to be calculated based on the acquired measurement data related to the biometric information of the wearing user.

[0029] The CPU 11 also controls the overall operation of the wearable terminal 1, such as communication via the first short-range wireless communication unit 15. Note that the control by the CPU 11 is similar to the operation of the wearable terminal 1 itself, and therefore the wearable terminal 1 may be described as the subject.

[0030] The RAM 12 is an example of a first storage unit of the present invention, and is a volatile memory that temporarily stores various data, calculation results by the CPU 11, and the like. For example, as an example of various data, biometric information of the wearer, which will be described later, is stored.

[0031] The ROM 13 is a non-volatile memory that stores programs and the like (for example, software (applications) corresponding to the management system A of this embodiment).

[0032] The biological information acquisition unit 14 includes a sensor that acquires so-called vital data and motion status of the user wearing the device. The biometric information acquisition unit 14 is equipped with, for example, a pulse sensor, a temperature sensor, a pulse wave sensor, a gyro sensor, a compass, an acceleration sensor, etc., and measures biometric information such as heart rate, blood oxygen saturation, body temperature, number of steps, sleep state (autonomic nervous recovery, REM sleep, non-REM sleep), number of floors climbed, distance traveled, etc.

[0033] In addition, based on the measurement results of the sensors equipped in the biometric information acquisition unit 14, the CPU 11 obtains biometric information such as breathing rate, various workouts such as muscle training workouts, aerobic workouts, anaerobic workouts, interval training, REP count, pitch, Vo2MAX, training load, stress level, recovery measurement, and fitness test.

[0034] Furthermore, based on the measurement results of the sensors included in the biological information acquisition unit 14, the CPU 11 also determines an abnormal state as biological information. For example, when the CPU 11 detects an abnormality in vital data such as an abnormally low temperature or a drop in pulse rate, or an abnormality in operating status due to a sudden change in acceleration (e.g., a fall) by comparing the data with a preset threshold, it records the abnormal condition as biometric information (records an abnormality flag).

[0035] The first short-range wireless communication unit 15 is, for example, a communication interface that communicates in a short-range communication area CA (see Figure 1) such as Bluetooth (registered trademark), and periodically transmits data via broadcast communication to unspecified devices within the short-range communication area CA of the first short-range wireless communication unit 15. It is needless to say that broadcast communication is a form of communication that can be received by any unspecified device. Furthermore, the cycle of data transmission may be variable as will be described later.

[0036] FIG. 3 is a diagram showing an example of a format of data transmitted by the first short-range wireless communication unit 15 according to the first embodiment of the present invention. As shown in FIG. 3, the data transmitted by the first short-range wireless communication unit 15 includes, for example, the biometric information of the wearer acquired by the biometric information acquisition unit 14 (including biometric information calculated by the CPU 11 based on the information), user identification information (described below) that identifies the wearer, and reception recognition information (described below) that enables the relay device (in this embodiment, the light bulb 2) of the management system A that receives the data to recognize that the data has been transmitted from the first short-range wireless communication unit 15 of the wearable terminal 1 of the management system A upon reception. The acquisition date and time shown in FIG. 3 is the date and time when the biometric information acquisition unit 14 acquired the biometric information.

[0037] The user identification information may be, for example, a MAC address assigned to each device capable of communication, but may also be unique identification information assigned to each wearable terminal 1 by the system operator who manages the management system A.

[0038] In addition, the received identification information may be, for example, a company ID, which is a unique number assigned to SIG member companies by the Bluetooth (registered trademark) SIG (Special Interest Group), but it is not limited to this and may also be unique identification information determined by the system operator who manages management system A to indicate that management system A is being used.

[0039] The power generation unit 16 is, for example, a power generation unit 16 that generates electricity by thermoelectric generation using a thermoelectric element to convert thermal energy into electrical energy, which is used in small terminals, but it may also be a power generation unit that generates electricity by vibration using a piezoelectric element or the like, and is preferably a power generation unit 16 that generates electricity by physical activity (thermal energy from body temperature, vibration from movement), which can eliminate the hassle of charging, etc.

[0040] For example, if the power generation unit 16 generates electricity using thermoelectric power generation, then given its power generation capacity, it can continuously broadcast data of approximately 40 bytes to unspecified devices in the vicinity at a frequency of approximately once every three seconds.

[0041] In addition, since it is sufficient to allocate one byte to each item to handle the data of the above-mentioned items of biometric information, even if all the above-mentioned items of biometric information are digitized, it will fit comfortably within 40 bytes. For this reason, although the power generation unit 16 that generates power through physical activity has a small power generation capacity, it can perform continuous data communication of biometric information, etc., if the frequency is about once every three seconds, and from this perspective, it is preferable to keep the data to be broadcasted at 40 bytes or less per communication.

[0042] However, if the data transmission cycle is set to a cycle longer than 3 seconds, the number of data transmissions will be reduced, which will reduce power consumption and make it possible to transmit data with a larger data capacity. Therefore, the data capacity of the data to be broadcast is not necessarily limited to 40 bytes or less.

[0043] Furthermore, the wearable terminal 1 may be configured to avoid power loss by varying the data transmission cycle to lengthen or shorten it depending on the remaining amount of power.

[0044] (Light bulb 2) FIG. 4 is a diagram illustrating the configuration of the light bulb 2 serving as the relay device of the first embodiment according to the present invention. The light bulb 2, which serves as a relay device, is suitable for use as lighting in places that the wearer frequently uses on a daily basis, such as a toilet or kitchen, and is equipped with a CPU 21, a RAM 22, a ROM 23, a second short-range wireless communication unit 24, a second communication unit 25, and a human presence sensor 26, which are connected so as to be accessible via a bus 27.

[0045] The place where the light bulb 2 is used is not limited to the above, and the above example is merely an example. Furthermore, the shape of the light bulb 2 is arbitrary and need not be limited to an incandescent bulb shape, but may be a fluorescent lamp shape. Furthermore, instead of the CPU 21, the RAM 22, and the ROM 23, an integrated circuit or the like may be used.

[0046] The CPU 21 is a central processing unit that loads a program stored in the ROM 23 into the RAM 22 and controls various controls and arithmetic processes in accordance with the program. For example, it controls the overall control of the light bulb 2, such as turning the light on and off based on the detection signal of the human presence sensor 26 described below, and controls associated with transmission and reception. Note that the control by the CPU 21 is similar to the operation of the light bulb 2 itself, and therefore the explanation will be given with the light bulb 2 as the subject.

[0047] The CPU 21 also functions as a data reception recognition unit that recognizes the reception of data transmitted from the first short-range wireless communication unit 15. That is, the light bulb 2 serving as the relay device has a data reception recognition unit as a functional configuration according to the program of the CPU 21.

[0048] Specifically, the CPU 21 as a data reception recognition unit performs a data reception recognition process to recognize the reception of data transmitted from the first short-range wireless communication unit 15 based on the reception recognition information described above contained in the data transmitted from the first short-range wireless communication unit 15 (see Figure 3) among the data received by the second short-range wireless communication unit 24 described below. This allows a distinction to be made between data from unrelated devices and data from unrelated devices.

[0049] The RAM 22 is a volatile memory that temporarily stores various data, calculation results by the CPU 21, and the like.

[0050] The ROM 23 is a non-volatile memory that stores programs and the like (for example, software (applications) corresponding to the management system A of this embodiment), and the reception recognition information described above is registered in the ROM 23 at the time of shipment. Therefore, it is possible to check whether the data is transmitted from the first short-range wireless communication unit 15 described above.

[0051] The second short-range wireless communication unit 24 is a communication interface that performs short-range communication such as Bluetooth (registered trademark), and receives data transmitted by broadcast communication from the first short-range wireless communication unit 15 of the wearable terminal 1.

[0052] Furthermore, based on an instruction from the CPU 21, the second short-range wireless communication unit 24 performs connection processing to automatically establish a communication connection with the wearable terminal 1 if a preset permission condition for data communication is satisfied. The pre-set conditions for permitting data communication are, for example, only once a day (limited number of times within a specified period), and the frequency is managed by the server 3 described below.If the server 3 is within the limited number of times, it issues an instruction to the light bulb 2 to establish a communication connection, and the connection process is carried out.

[0053] Specifically, when the data via the broadcast communication described above reaches the server 3 and the server 3 recognizes that it can communicate with the wearable terminal 1, if a communication connection has not been established today, the server 3 sends an instruction to the light bulb 2 to establish a communication connection, and the above-mentioned connection processing is carried out based on that instruction.

[0054] In this embodiment, the first short-range wireless communication unit 15 and the second short-range wireless communication unit 24 are Bluetooth (registered trademark), and therefore the above-described connection process is so-called pairing.

[0055] Then, based on instructions from the CPU 21, the second short-range wireless communication unit 24 requests the wearable terminal 1 to transmit the biometric information and user identification information stored in RAM 12 (first storage unit), and performs a connection status reception process to receive the biometric information and user identification information stored in RAM 12 (first storage unit) transmitted from the first short-range wireless communication unit 15 in a communication connection state (pairing state in this example).

[0056] Thereafter, the second short-range wireless communication unit 24, based on an instruction from the CPU 21, performs a connection release process (cancelling pairing in this example) to automatically release the communication connection after the connection status reception process. In this communication connection state, processing is performed in a state in which the light bulb 2 recognizes the wearable device 1, so there is no need to add reception recognition information to the data transmitted by the first short-range wireless communication unit 15.

[0057] In this way, it is possible to obtain biometric information that could not be received via broadcast communication, that is, information obtained while the light bulb 2 was outside the short-range communication area CA because the wearer was out, for example, while limiting the power-intensive communication connection state to only certain limited conditions, thereby avoiding the wearable terminal 1 from running out of power, etc.

[0058] In this embodiment, the second communication unit 25 is a long-distance wireless communication unit capable of long-distance communication (for example, a communication interface capable of communication in accordance with standards such as LTE (registered trademark), 4G, and 5G), and is therefore connected to the network N via the base station CS.

[0059] However, since the second communication unit 25 only needs to be able to communicate with the server 3, it may be a communication interface that can be connected to the Internet via a wired connection. Furthermore, if the light bulb 2 is used in an environment where a Wi-Fi (registered trademark) router is present, the second communication unit 25 may be a communication interface that complies with standards such as Wi-Fi (registered trademark).

[0060] Then, based on instructions from the CPU 21, the second communication unit 25 performs a data transmission process to transmit the data (see Figure 3) from the first short-range wireless communication unit 15 recognized in the data reception recognition process described above to the third communication unit 34 of the server 3 described later.

[0061] In addition, based on instructions from the CPU 21, the second communication unit 25 performs a connection status acquisition data transmission process to transmit the biometric information and user identification information received in the connection status reception process to the third communication unit 34 of the server 3, which will be described later. The data of the biometric information and user identification information received in the connection status receiving process is the same as the multiple pieces of data shown in FIG. 3, and the items of the information itself are the same as those in FIG.

[0062] The human presence sensor 26 may be, for example, a sensor that uses an infrared sensor to detect the presence of a person, and the CPU 21 controls the on / off of the light bulb 2 based on the detection result.

[0063] Therefore, the light bulb 2 of this embodiment can be powered on at all times, and the communication functions of the second short-range wireless communication unit 24 and second communication unit 25 described above are kept in a usable state at all times.

[0064] However, in rooms where people are active, the lights are usually on, and data can be sent and received when the lights are on, so it is not essential to have a human presence sensor 26.

[0065] [Server 3] FIG. 5 is a diagram illustrating the configuration of the server 3 according to the first embodiment of the present invention. The server 3 manages the biometric information of each wearer of the management system A on a user-by-user basis, and is responsible for managing the entire system, such as transmitting the biometric information of a specific wearer that has been permitted to be acquired to the reception-permitted terminal 4 at a pre-set timing or in response to a request from the reception-permitted terminal 4, which has been permitted to acquire the biometric information of the specific wearer.

[0066] The server 3 includes a database DB, a CPU 31, a RAM 32, a ROM 33, and a third communication unit 34, and the CPU 31, RAM 32, ROM 33, and the third communication unit 34 are connected so as to be accessible via a bus 35, and the third communication unit 34 is connected so as to be accessible to the database DB. The CPU 31, the RAM 32, and the ROM 33 may be replaced by an integrated circuit or the like.

[0067] Furthermore, the server 3 may be a cloud server that utilizes cloud computing technology. In this case, the software will be used to create a virtual computer that performs the same functions as a physical computer, and the data storage area provided by the cloud service provider will be used as the database.

[0068] Therefore, please note that the following description of the processing performed by CPU 31, RAM 32, ROM 33, and third communication unit 34 also describes the processing content when the entire operation is realized as a software functional configuration using a data storage area provided by a cloud service provider as the memory unit.

[0069] The database DB includes a user management memory area (an example of a user management unit of the present invention) in which user-related information including user identification information that identifies the wearer is registered, and a biometric information memory area (an example of a third memory unit of the present invention) in which data transmitted from the first short-range wireless communication unit 15 (i.e., biometric information for each wearer) is stored in association with the user identification information of the wearer.

[0070] FIG. 6 is a diagram for explaining the user management storage area (user management unit) of the first embodiment according to the present invention. As shown in Figure 6, the user management memory area (hereinafter also referred to as the user management section) registers the user name of the wearer, the serial number of the wearable terminal 1, the MAC address of the wearable terminal 1, and information on permitted receiving terminals for each wearer.

[0071] We will explain in detail how the information is registered using examples below, but please note that the examples below are merely examples and are not intended to be limiting.

[0072] When the wearable terminal 1 is shipped to the wearer, a shipping inspection is performed, and the MAC address of the wearable terminal 1 is acquired during this inspection.

[0073] FIG. 7 is a diagram for explaining the contents of the shipping inspection according to the first embodiment of the present invention. The shipping inspection is performed using an inspection device MC shown in FIG. 7, and the wearable device 1 before shipping is placed on the inspection device MC.

[0074] The inspection device MC then detects that the wearable terminal 1 has been placed on the inspection device MC based on the radio wave strength of the broadcast communication from the wearable terminal 1, assigns a serial number to the wearable terminal 1, and obtains the MAC address included in the broadcast communication data.

[0075] Then, the inspection device MC prints a two-dimensional barcode including the MAC address of the wearable device 1 and the web address for initial access, which are acquired from a printing device (not shown), and a registration code. This two-dimensional barcode is included in the wearable device 1. Furthermore, the inspection device MC registers the assigned serial number and the acquired MAC address of the wearable device 1 in the user management unit shown in FIG.

[0076] When the user receives the wearable device 1 and reads the attached two-dimensional barcode or registration code using the reader function of a smartphone or other device, they are directed to a user registration screen, where they tap the completion button to complete the registration. The registration screen may be configured so that information such as age and gender can also be entered.

[0077] During this registration, the server 3 receives the entered name (which may include age and gender) and the MAC address contained in the two-dimensional barcode, and registers the entered name (which may include age and gender) in the user name field for the same MAC address in the user management section.

[0078] In addition to the above, if, for example, a relative of the wearer wishes to view the wearer's biometric information, since it is personal information, they can go through the procedures for viewing and register the device (e.g., smartphone, tablet, etc.) to be used for viewing, and the information on the device that has completed the procedures will be registered in the permitted receiving device information (e.g., ID, password, MAC address, email address, etc.). The terminals registered in this permitted reception terminal information are the permitted reception terminals 4 described later.

[0079] By the way, to digress a little, the light bulb 2 is also shipped in the same manner as the wearable device 1 described above.

[0080] That is, prior to shipping, a serial number is assigned and a MAC address is acquired, and these are then registered in the light bulb management storage area (also called the light bulb management section) of the database DB. Before shipping, the second short-range wireless communication unit 24 of the light bulb 2 is set to receive broadcast communication data.

[0081] The user of the light bulb 2 (who may be a different user from the wearer, such as a relative, a manager of a public facility including a hospital, or a manager of a nursing home) reads the two-dimensional barcode attached to the light bulb 2 using a reader function on a smartphone or other device, and is directed to a basic information registration screen.

[0082] For example, by entering the name, location of use (installation location such as kitchen or toilet, and address, etc.), contact information (email address, etc.), etc. and tapping the complete button on the basic information registration screen, registration is completed. During this registration, the server 3, as before, receives the entered name, location of use, contact information, etc., as well as the MAC address of the light bulb 2 contained in the two-dimensional barcode, and registers the entered name, location of use, contact information, etc., in the same MAC address in the light bulb management section.

[0083] When the light bulb 2 sends data from the wearable terminal 1 to the server 3, it also adds the MAC address of the light bulb 2. Therefore, the server 3 can refer to the light bulb management unit, obtain the usage location of the MAC address that is the same as the MAC address of the light bulb 2, and record the location where the biometric information was obtained together with the biometric information managed for each wearer, as described below.

[0084] FIG. 8 is a diagram for explaining the biometric information storage area (third storage unit) according to the first embodiment of the present invention. As shown in Figure 8, the biometric information storage area stores, for example, the username of the wearer and the MAC address of the wearable device 1, which is user identification information, in each registered file, and the biometric information is stored in chronological order based on the acquisition date and time when the biometric information was acquired.

[0085] In FIG. 8, the abnormal state is shown as "0", but as explained above, if there is an abnormality in the biological information, it is set to "1". As explained above, an acquisition location, which is an item relating to the location where the biometric information was acquired, may also be added.

[0086] The CPU 31 is a central processing unit that loads a program stored in the ROM 33 into the RAM 32 and controls various controls and arithmetic processes in accordance with the program. For example, based on the user identification information (MAC address of the wearable terminal 1) contained in the data (see Figure 3) transmitted from the first short-range wireless communication unit 15 received via the light bulb 2, the received data is stored in the biometric information storage area of ​​the database DB (an example of the third storage unit of the present invention).

[0087] Furthermore, if the abnormality flag of the biometric information of the received data indicates an abnormality ("1") in the wearing user, the user management section of the database DB is referenced, and based on the user identification information (MAC address of the wearable terminal 1), an email or the like notifying the abnormality of the reception-permitted terminal 4 of the reception-permitted terminal information is sent from the third communication section 34 described below.

[0088] The RAM 32 is a volatile memory that temporarily stores various data, calculation results by the CPU 31, and the like.

[0089] The ROM 33 is a non-volatile memory that stores programs and the like (for example, software (applications) corresponding to the management system A of this embodiment).

[0090] The third communication unit 34 is a communication interface for communicating with the light bulb 2 and the reception-permitted terminal 4 via the network N, and for accessing the database DB.

[0091] [Device 4 that is permitted to receive] As mentioned earlier, the permitted receiving terminal 4 may be any ordinary smartphone or tablet equipped with a general communication function (an example of the fourth communication unit of the present invention) capable of communicating with the server 3, and a description of its configuration will be omitted.

[0092] This permitted reception terminal 4 is a terminal that is permitted to acquire (registered for acquisition) biometric information about the wearer, and is used by a relative of the wearer (for example, the wearer's daughter or son) who is concerned about the wearer, with the wearer's permission.

[0093] Although the above discussion focuses on relatives, this does not prevent a third party's device from being registered, for example, in relation to caregiving. In addition, if permission to use the biometric information has been obtained from the wearer, the information may be provided to a corporation or other entity that is permitted to use the information, and the permitted reception terminal 4 may be a terminal that is permitted to access the information in this case.

[0094] Next, the overall operation of the management system A will be described. As already mentioned, the first short-range wireless communication unit 15 of the wearable device 1 periodically broadcasts data including biometric information to unspecified devices within the short-range communication area CA of the first short-range wireless communication unit 15, so there is no need for any cumbersome settings to establish a communication connection.

[0095] The data transmitted from the first short-range wireless communication unit 15 includes reception recognition information, and the light bulb 2 located within the short-range communication area CA performs a data reception process in which the second short-range wireless communication unit 24 receives data including data other than the data transmitted from the first short-range wireless communication unit 15 (data from unrelated devices).

[0096] Therefore, the data reception recognition unit (CPU 21) of the light bulb 2 performs a data reception recognition process in which, among the data received by the second short-range wireless communication unit 24, the data reception recognition unit recognizes the reception of data transmitted from the first short-range wireless communication unit 15 based on the reception recognition information.

[0097] Next, the light bulb 2 performs a data transmission process in which the data received in the data reception process is transmitted from the second communication unit 25 to the third communication unit 34 of the server 3. Since this data transmission process is a process in which the data from the first short-range wireless communication unit 15 recognized in the data reception recognition process is transmitted from the second communication unit 25 to the third communication unit 34 of the server 3, the server 3 does not need to receive unrelated data, and the management system A can be configured with a reduced processing load.

[0098] However, the server 3 can determine whether the data is unrelated to the management system A by referring to the MAC address included in the received data.

[0099] Therefore, as a management system A that omits the contents of the received recognition information described so far, the second communication unit 25 of the light bulb 2 performs a data transmission process to transmit data received in the data reception process, including data other than data transmitted from the first short-range wireless communication unit 15 (data from unrelated devices), to the third communication unit 34 of the server 3, and if the data received by the third communication unit 34 from the second communication unit 25 includes user identification information (MAC address of the wearable terminal 1), the server 3 may store biometric information for each user wearing the wearable terminal in the third memory unit based on the user identification information.

[0100] However, in this case, the server 3 will receive a large amount of data, including irrelevant data. Therefore, it is preferable to make the determination at the stage of individual reception at the light bulb 2, and as explained above, the data should include reception confirmation information, and the light bulb 2, which is the relay device, should be equipped with a data reception recognition unit that recognizes the receipt of the data transmitted from the first short-range wireless communication unit 15 based on the reception confirmation information.

[0101] Let's get back to the topic. As described above, the server 3 manages the biometric information for each wearer, and transmits the biometric information of a specific wearer that has been permitted to be acquired to the reception-permitted terminal 4 at a pre-set timing or in accordance with a request from the reception-permitted terminal 4.

[0102] Therefore, the owner of the authorized reception terminal 4 can check the health condition of the wearer, and for example, if the wearer's physical condition does not seem to be good, although it is not abnormal, they can take the wearer to the hospital.

[0103] Furthermore, as explained above, if the biometric information of the wearer is abnormal, the server 3 notifies the authorized receiving terminal 4 of the abnormality, so that the owner of the authorized receiving terminal 4 can contact an ambulance or the like (which may be an attendant contracted by management system A) or rush to the scene himself.

[0104] As mentioned earlier, if the biometric information recorded in the biometric information storage area (third storage unit) includes the location of acquisition, which is an item related to the location where the biometric information was acquired, this is preferable because it allows for more accurate identification of the location where the person needs to rush to.

[0105] It is also possible to add a long-distance communication unit capable of long-distance communication to the wearable device 1, and activate the long-distance communication unit to transmit data to the server 3 when the biological information is abnormal. Since long-distance communication consumes a lot of power, it is preferable to start the communication only when an abnormality occurs, as described above, and stop the communication after transmitting biometric information (including an abnormality flag, etc.) a preset number of times (for example, several times) to avoid power loss to the wearable terminal 1.

[0106] [Second embodiment] Next, with reference to FIG. 9, a management system A that manages biological information transmitted by broadcast communication according to a second embodiment of the present invention will be described. FIG. 9 is a diagram for explaining a management system A according to the second embodiment of the present invention. The second embodiment has the same basic configuration as the first embodiment, and the following mainly describes the differences from the first embodiment, and may omit a description of the similarities.

[0107] As shown in Figure 9, the management system A of the second embodiment includes a mobile terminal 5 on which software (application) is installed to provide a functional configuration as a data reception recognition unit that recognizes the reception of data transmitted from the first short-range wireless communication unit 15.

[0108] The mobile terminal 5 may be a general smartphone or tablet terminal, and may be, for example, a terminal on which software (application) is installed that gives the reception permitted terminal 4 described above the functional configuration of a reception recognition unit.

[0109] Alternatively, the device may be a smartphone or tablet device owned by another user wearing the wearable device 1, on which software (application) that provides the device with the functional configuration as the reception recognition unit is installed.

[0110] That is, the mobile terminal 5 may be any mobile terminal on which software (application) that provides the functional configuration of a reception recognition unit is installed, and the owner of the mobile terminal 5 is not particularly limited.

[0111] Then, similarly to the first embodiment, when the mobile terminal 5 enters the short-distance communication area CA of the wearable terminal 1, it transmits data to the server 3 as a relay device, similarly to the light bulb 2 described above. That is, the mobile terminal 5 is an example of a relay device of the present invention, and has the same configuration as the light bulb 2 in terms of the communication section and the like. However, the software (application) installed on the mobile terminal 5 does not perform connection processing for establishing a communication connection with the wearable terminal 1.

[0112] As can be seen from the explanation so far, the wearable terminal 1 performs broadcast communication, so that data can be received by unspecified devices, but in order to identify the user wearing the terminal, information from the user management unit provided in the server 3 is required.

[0113] Therefore, it is possible to construct a management system A in which individuals cannot be identified even if a terminal such as the mobile terminal 5 functions as a relay device. Furthermore, as the number of such portable terminals 5 that support the management system A increases, the number of relay spots that relay the data (data including biometric information) transmitted from the first short-range wireless communication unit 15 will increase. For example, even when the wearer is out, the biometric information can be stored in the server 3 when passing by the owner of the portable terminal 5, making it possible to manage biometric information in more detail.

[0114] [Third embodiment] Next, a rescue system B (hereinafter also referred to as rescue system B) using biological information transmitted by broadcast communication according to a third embodiment of the present invention will be described with reference to FIG. FIG. 10 is a diagram for explaining a rescue system B according to the third embodiment of the present invention. Rescue system B also has a configuration similar to that of management system A described so far, and for configurations similar to those described so far, the same symbols and numbers are used in Figure 10, and explanations may be omitted.

[0115] As already explained, the wearable device 1 performs broadband communication with unspecified devices. Therefore, as shown in FIG. 10, even if the device is caught up in a disaster such as a landslide, it continues to transmit radio waves. Moreover, the area in which first short-range wireless communication unit 15 can communicate is limited to a short distance.

[0116] Therefore, the rescue system B is equipped with a rescue support terminal 6 that can receive data from the first short-range wireless communication unit 15, and if the rescue support terminal 6 is used by, for example, a rescue team or the like, they can receive the radio waves by getting close to the user wearing the terminal. Conversely, if radio signals can be received, it means that the person in distress is nearby.

[0117] However, the light bulb 2 and the mobile terminal 5 of the management system A only functioned as relay devices, and only the server 3 knew whether or not they were receiving data from the wearable terminal 1.

[0118] Therefore, the rescue support terminal 6 has a configuration similar to that of the light bulb 2 and the mobile terminal 5, and is equipped with a notification unit that notifies the presence and biometric information of the wearing user, and the data reception recognition unit of the rescue support terminal 6, as before, performs a data reception recognition process in which, of the data received by the second short-range wireless communication unit 24, the data reception recognition unit recognizes the reception of data transmitted from the first short-range wireless communication unit 15 based on the reception recognition information, and notifies the data from the first short-range wireless communication unit 15 recognized in the data reception recognition process to, for example, a rescue team, etc., that is using the rescue support terminal 6, via the notification unit.

[0119] That is, the rescue support terminal 6 performs a rescue information notification process to notify the wearer of presence information within the short-range communication area CA of the first short-range wireless communication unit 15 and the wearer's biological information through the notification unit. As in the past, the rescue support terminal 6 has a communication unit configuration similar to that of the light bulb 2, and also functions as a relay device that transmits data to the server 3.

[0120] Furthermore, the rescue support terminal 6 is equipped with a radio wave intensity detection unit that detects radio wave intensity, and the rescue support terminal 6 performs a radio wave intensity detection process using the radio wave intensity detection unit to detect the radio wave intensity at the time of receiving data that the data reception recognition unit recognizes as data from the first short-range wireless communication unit 15 based on the reception recognition information.

[0121] Then, the rescue support terminal 6 performs a radio wave intensity notification process to notify the radio wave intensity detected in the radio wave intensity detection process through the notification unit.

[0122] This makes it easier for a rescue team or the like using the rescue support terminal 6 to find a distressed user by heading in the direction of the notified radio wave strength that is stronger.

[0123] From the viewpoint of rescue operations, the server 3 and the reception-permitted terminal 4 are unnecessary, and the rescue system B does not necessarily have to include the server 3 and the reception-permitted terminal 4. However, the presence of the server 3 has the advantage of making it possible to keep a log of changes in the wearer's biometric information during the rescue operation, and the presence of the reception permission terminal 4 allows those concerned about the wearer to know the wearer's physical condition, so it is preferable that the rescue system B be equipped with the server 3 and the reception permission terminal 4.

[0124] [Fourth embodiment] Next, with reference to FIG. 11, a description will be given of a physical condition management system C (hereinafter also referred to as physical condition management system C) that uses biological information transmitted by broadcast communication of a driver according to a third embodiment of the present invention. FIG. 11 is a diagram for explaining a physical condition management system C according to the fourth embodiment of the present invention.

[0125] The health management system C also has a configuration similar to that of the management system A described so far, and for configurations similar to those described so far, the same symbols and numbers are used in Figure 11, and explanations may be omitted.

[0126] In the physical condition management system C, the user who wears the system is a driver who drives a vehicle, and instead of the light bulb 2, the system is equipped with an in-vehicle device 7 (for example, a car navigation system) that is installed in the vehicle.

[0127] In addition to having the same configuration as the light bulb 2, the in-vehicle device 7 also has a health condition determination unit that determines the health condition of the wearer based on biometric information, and a notification unit that notifies the wearer of the health condition of the wearer.

[0128] Therefore, the physical condition determination unit performs a physical condition determination process to determine whether there is a problem with the physical condition based on the biometric information of the data from the first short-range wireless communication unit 15, and if the physical condition determination process determines that there is a problem, it performs a physical condition notification process to notify the wearing user that there is a problem with their physical condition via the notification unit.

[0129] For example, the physical condition assessment unit compares vital data (heart rate, body temperature, etc.) with pre-set thresholds, detects abnormalities in vital signs, and notifies the driver, who is the wearer, via the notification unit to encourage them to rest, thereby preventing accidents, etc.

[0130] From the viewpoint of managing one's physical condition while driving, the server 3 and the reception permitted terminal 4 are unnecessary, and the physical condition management system C does not necessarily have to include the server 3 and the reception permitted terminal 4. However, the presence of the server 3 makes it possible to keep a log of changes in the biometric information of the wearer who is the driver while driving. Furthermore, if there is a reception permission terminal 4, there is an advantage that a manager of a transportation company or the like that uses the physical condition management system C can check the physical condition of the driver. Therefore, it is preferable that the physical condition management system C includes a server 3 and a reception-permitted terminal 4.

[0131] Although the present invention has been described above based on specific embodiments, the present invention is not limited to the above embodiments.

[0132] For example, the wearable terminal 1 may include, instead of the power generation unit 16, a primary battery or a rechargeable secondary battery.

[0133] Furthermore, in addition to the power generation unit 16, the wearable terminal 1 may also include a primary battery and a rechargeable secondary battery.

[0134] However, since the wearable terminal 1 is provided with the power generation unit 16 described above, it is still preferable that the wearable terminal 1 is provided with the power generation unit 16, as this makes it less susceptible to power loss.

[0135] As described above, the present invention includes modifications and improvements to the embodiments within the technical scope of the invention, and this will be clear to those skilled in the art from the description of the claims. [Explanation of symbols]
