[0025] Hereinafter, embodiments of a monitoring device, a monitoring management device, and a monitoring system of the present invention will be described with reference to the drawings.

[0026] First Embodiment FIG. 1 is an overall view of a monitoring system 1 according to a first embodiment. The monitoring system 1 includes, for example, a monitoring device 100 and a monitoring management device 300. The monitoring device 100 is connected to the monitoring management device 300 via a first terminal device 200 and a second terminal device 400 and a network NW. The network NW includes, for example, the Internet, a LAN (Local Area Network), a wireless base station, a provider device, and the like. The monitoring device 100 and the first terminal device 200 are connected by short-range communication such as Bluetooth (registered trademark). A plurality of beacon transmitters 500 are installed, for example, in a factory where a user works.

[0027] The beacon transmitter 500 wirelessly transmits a signal (e.g., an RFID signal) once every few seconds within a radius of several meters to several tens of meters. The beacon transmitters 500 are installed, for example, at regular intervals in the user's work area. The beacon transmitter 500 includes, for example, a transmitter ID. It is assumed that the monitoring device 100 knows in advance the installation location of the beacon transmitter 500 corresponding to the transmitter ID.

[0028] The components of each device will be described below. The monitoring device 100 includes, for example, a communication unit 110, pressure sensors 120L and 120R, acceleration sensors 130L and 130R, a temperature sensor 140, a position detection unit 160, a report unit 170, and a beacon receiver 185. The monitoring device 100 is a device that is built into or housed in a shoe and detachably attached, and includes components for the left foot and the right foot. The communication unit 110, the temperature sensor 140, the blood pressure sensor 150, the pulse sensor 155, the position detection unit 160, the report unit 170, and the beacon receiver 185 are provided on either the left foot or the right foot, or on both. Hereinafter, when there is no need to distinguish between the sensor for the left foot and the sensor for the right foot, the symbols L and R indicating whether the sensor is for the left foot or the right foot may be omitted in the description. The monitoring device 100 may be, for example, a device that is built into an insole or an insole, or a device that is detachably attached to the insole or an inner sole. Also, each part constituting the monitoring device 100 may be, for example, built into the shoe, the insole, the shoe and the ankle band, or the insole and the ankle band. Also, it is desirable to have a plurality of pressure sensors 120L and 120R for each of the left foot and the right foot.

[0029] The communication unit 110 communicates with the watching management device 300, for example, via the first terminal device 200 and the network NW. Alternatively, the communication unit 110 may connect to the network NW and communicate with the watching management device 300 without going through the first terminal device 200. The same applies to the second embodiment.

[0030] The beacon receiver 185 receives a signal emitted by the beacon transmitter 500 and acquires the transmitter ID.

[0031] The pressure sensor 120 is a device that measures the pressure of the user's foot using a pressure-sensitive element, converts it into an electrical signal, and outputs it.

[0032] The acceleration sensor 130 is, for example, a three-axis acceleration sensor, which is a device that converts the acceleration of each of the three axes into an electric signal and outputs it. Since the acceleration of each of the three axes detected by the acceleration sensor includes a weight acceleration component, it is possible to detect the inclination, tilt, and vibration of the user's foot. The acceleration sensor 130 may be, for example, a gyro sensor.

[0033] The temperature sensor 140 measures the temperature of the user's foot and / or the outside air temperature, converts it into an electrical signal, and outputs it.

[0034] The blood pressure sensor 150 is, for example, a blood pressure sensor that utilizes the principle that the amount of reflected light changes according to the change in blood flow. The blood pressure sensor 150 applies light to a blood vessel, calculates a pulse wave from the amount of change in the reflection of the light, and calculates blood pressure from the characteristic amount of the pulse wave. The blood pressure sensor 150 converts the converted blood pressure into an electrical signal and outputs it.

[0035] For example, the pulse sensor 155 shines light on the user's leg, detects the light reflected by blood vessels, and measures the pulse from the change over time in the amount of light. The pulse sensor 155 is a device that converts the measured pulse into an electrical signal and outputs it. Note that the blood pressure sensor 150 and the pulse sensor 155 may be devices that use microwave sensors.

[0036] The position detection unit 160 detects the position of the monitoring device 100 (i.e., the user's position) based on the transmitter ID acquired by the beacon receiver 185, for example. Since the position detection unit 160 can detect the installation location of the beacon transmitter 500 from the transmitter ID, it may detect the installation location of the detected beacon transmitter 500 as the user's position, or when multiple transmitter IDs are acquired, it may detect the user's position based on the principle of triangulation taking into account the reception strength. In addition, the position detection unit 160 may detect the user's position using information from a GPS receiver (not shown) of the first terminal device 200. The GPS receiver may be built into or housed in a shoe, or may be attached in a detachable state, for example.

[0037] The position detection unit 160 may also perform short-distance wireless communication with devices installed around the user and detect the user's position based on the acquired installation locations of the surrounding devices. The short-distance wireless communication may be, for example, Bluetooth. In that case, the monitoring device 100 may have a beacon transmitter.

[0038] The report unit 170 outputs the output values ​​of the various sensors together with, for example, the position detected by the position detection unit 160 to the watching management device 300 via the communication unit 110 and the first terminal device 200.

[0039] The first terminal device 200 and the second terminal device 400 are devices that can be connected to a network NW, such as a smartphone or a tablet terminal. The first terminal device 200 is carried by a user, and the second terminal device 400 is carried by an administrator of the user. In the second terminal device 400, for example, a monitoring application runs, and displays or notifies output values ​​of various sensors and the location and number of times the user has fallen. For example, the display method is to display an image showing the location and number of times the user has fallen. For example, the notification method is sound or vibration.

[0040] The monitoring management device 300 includes, for example, a communication unit 310, a determination unit 320, an output unit 330, and an alarm unit 340. The components other than the communication unit 310 are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transient storage medium) such as an HDD (Hard Disk Drive) or a flash memory, or may be stored in a removable storage medium (a non-transient storage medium) such as a DVD or a CD-ROM, and may be installed by mounting the storage medium in a drive device.

[0041] The communication unit 310 is a communication interface for connecting to the network NW. The communication unit 310 communicates with the watching apparatus 100 via the first terminal apparatus 200.

[0042] The determination unit 320 obtains, for example, output values ​​of the pressure sensor 120 and the acceleration sensor 130, and determines whether or not the user has fallen based on these values. The determination unit 320 may determine whether or not the user has fallen based only on the output value of the pressure sensor 120.

[0043] (1) For example, when the output values ​​of all the pressure sensors 120 of both feet are less than the threshold value, the determination unit 320 determines that the user has fallen.

[0044] (2) The judgment unit 320 may determine that the user has fallen if the output values ​​of all pressure sensors 120 on both feet are less than the threshold value and the angle of the acceleration sensor 130 changes rapidly (for example, the resultant acceleration exceeds the threshold value within one second).

[0045] (3) The determination unit 320 may determine that the user has fallen if the current position of the user detected by the position detection unit 160 indicates a place other than a specific place and the output values ​​of all the pressure sensors of both feet are less than the threshold value. The specific place may be, for example, the user's resting place or a dressing room.

[0046] (4) The determination unit 320 may determine that the user has fallen when the output value of the pressure sensor 120 of one foot is 0 and the output value of the pressure sensor 120 of the other foot is less than a threshold value. For example, this is the case when the user's shoe comes off on one foot and the user falls.

[0047] (5) The determination unit 320 may determine that the user has fallen when the output values ​​of the pressure sensors 120 of both feet are less than the threshold value and the output value of the blood pressure sensor 150 has changed by 20% or more based on the average blood pressure. The determination unit 320 may determine that the user has fallen using only the output value of the blood pressure sensor 150. In addition, when the blood pressure sensor 150 is measuring the blood pressure at the ankles, the determination unit 320 may detect postures with different heights to the heart, such as standing, sitting, and lying down, and determine that the user has fallen.

[0048] As a monitoring content other than a fall, the determination unit 320 may determine that the user has heat stroke or may have heat stroke when the output value of the temperature sensor 140 is equal to or greater than a threshold value. The determination unit 320 may determine that the user has heat stroke or may have heat stroke when the output value of a thermometer installed around the user is equal to or greater than a threshold value. Furthermore, the determination unit 320 may determine that the user has heat stroke or may have heat stroke when the output value of the pulse sensor 155 increases by 20% or more based on the average pulse rate.

[0049] The output unit 330 outputs the determination result of the determination unit 320 to the second terminal device 400. The output unit 330 may output, for example, a message or an image to be displayed on the screen of the second terminal device 400, or may output a sound of the contents of the determination result. The output unit 330 may output, for example, the current location of the user acquired from a GPS, or the installation location of the beacon transmitter 500 that is closest to the monitoring device 100.

[0050] The alarm unit 340 issues an alarm based on the determination result of the determination unit 320 from surrounding devices or the user's first terminal device 200. The alarm may be, for example, sounding a buzzer, turning on a light, vibrating the first terminal device 200, or the like.

[0051] Fig. 2 is a flowchart showing an example of an operation for detecting a fall according to the first embodiment. The flowchart in Fig. 2 shows an example of an operation in which the determination unit 320 determines whether or not the user has fallen based on the output values ​​of the pressure sensor 120 and the acceleration sensor 130. The current position of the user is acquired from the GPS receiver of the first terminal device 200.

[0052] The determination unit 320 acquires the output values ​​of the pressure sensors 120 of both feet and the acceleration sensors 130 of both feet from the report unit 170 via the communication unit 110 (step S100).

[0053] The position detection unit 160 acquires the current position of the user from the GPS receiver of the first terminal device 200 via the communication unit 110 (step S110).

[0054] The determination unit 320 determines whether the current location of the user acquired in step S110 is a location other than the specific location (step S120).

[0055] In the process of step S120, if the user's current location is a location other than the specific location, the determination unit 320 determines whether the output values ​​of the pressure sensors 120 of both feet are less than the threshold value (step S130). In the process of step S120, if the user's current location is a specific location, the process returns to step S100.

[0056] If the output values ​​of the pressure sensors 120 of both feet are less than the threshold value in the process of step S130, the determination unit 320 determines whether the output values ​​of the pressure sensors 120 of both feet are 0 or not (step S140).

[0057] If the output values ​​of the pressure sensors 120 of both feet are not 0 in the process of step S140, the determination unit 320 determines whether or not the change in the output values ​​of the acceleration sensors 130 of both feet is rapid (step S150).

[0058] In the process of step S150, if the change in output value of the acceleration sensors 130 of both feet is rapid, the determination unit 320 determines that the user has fallen (step S160).

[0059] In the processing of step S130, step S140, or step S150, if the output values ​​of the pressure sensors 120 of both feet are greater than the threshold value, or if the output values ​​of the pressure sensors 120 of both feet are 0, or if the change in the output values ​​of the acceleration sensors 130 of both feet is not sudden, the processing of step S100 is returned.

[0060] When the determination result of the determination unit 320 indicates that the user has fallen, the output unit 330 outputs the determination result to the first terminal apparatus 200 (step S170). After the determination result is output, the process returns to step S100, and the process of this flowchart is repeated.

[0061] Fig. 3 is a flowchart showing an example of the operation of detecting heat stroke according to the first embodiment. In the flowchart of Fig. 3, it is determined whether or not the user has heat stroke based on the output value of the temperature sensor 140. The current location of the user is acquired from the installation location linked to the sender ID of the beacon transmitter 500.

[0062] The determination unit 320 acquires the output value of the temperature sensor 140 from the report unit 170 via the communication unit 110 (step S200).

[0063] Next, the determination unit 320 determines whether the output value of the temperature sensor 140 acquired in step S200 is equal to or greater than a threshold value (step S210).

[0064] In the process of step S210, if the output value of the temperature sensor 140 is equal to or greater than the threshold value, the position detection unit 160 acquires the transmitter ID of the nearest beacon transmitter 500 via the communication unit 110. The position detection unit 160 identifies the current position of the user from the installation position of the beacon transmitter 500 linked to the transmitter ID (step S220).

[0065] If it is determined in step S210 that the output value of temperature sensor 140 is less than the threshold value, the process returns to step S200.

[0066] The output unit 330 outputs the determination result that the user has heat stroke and the current location of the user to the second terminal device 400 (step S230).

[0067] According to the above-mentioned first embodiment, the monitoring system 1 can determine that the user has fallen when the output values ​​of all the pressure sensors 120 of both feet of the monitoring device 100 are less than the threshold value. Furthermore, the monitoring system 1 can more accurately determine whether the user has fallen by using the output values ​​of the pressure sensor 120 and the acceleration sensor 130. If the output value of the pressure sensor 120 is less than the threshold value and the user's current location is a location other than the specific location, the monitoring system 1 can prevent erroneous detection in the user's rest area or changing room and notify only the user of a fall in the work area by determining that the user has fallen when the output value of the pressure sensor 120 of one foot is 0 and the output value of the pressure sensor 120 of the other foot is less than the threshold value, thereby determining that the user has fallen even if one shoe has come off. Furthermore, the monitoring system 1 can notify the administrator that the user has fallen by notifying the second terminal device 400 of the determination result. Therefore, the administrator can call the user to check on their safety or dispatch someone to check on them. The monitoring system 1 not only determines whether the user has fallen, but also outputs the result of the determination that the user has heatstroke to the second terminal device 400, allowing the administrator to take measures such as having the user rest quickly, and preventing heatstroke from becoming serious.

[0068] <Second embodiment> FIG. 4 is an overall view of a monitoring system 1A according to the second embodiment. The monitoring system 1A includes, for example, a monitoring device 100 and a monitoring management device 300. The monitoring device 100 and the first terminal device are connected by short-distance communication such as Bluetooth. The monitoring management device 300 plays a role in distributing information such as the judgment result judged by the monitoring device 100. The first terminal device 200, the monitoring management device 300, and the second terminal device 400 are connected via a network NW. The monitoring device 100 judges whether the user has fallen or suffered from heat stroke, and transmits the judgment result to the monitoring management device 300 via the first terminal device 200, and the monitoring management device 300 notifies the second terminal device 400. For convenience, these will be described with the same reference numerals as those in the first embodiment.

[0069] The watching device 100 further includes, for example, an alarm unit 180, a judgment unit 190, and an output unit 195. The alarm unit 180 issues an alarm from, for example, a surrounding device, the first terminal device 200 of the user, or the watching device 100 itself in response to the judgment result of the judgment unit 190. The alarm may be, for example, sounding a buzzer, turning on a light, or vibrating the first terminal device 200. The judgment unit 190 judges, for example, whether or not the user has fallen or whether or not the user has heat stroke from the output values ​​of various sensors. The judgment method of the judgment unit 190 may be the same as that of the judgment unit 320 in the first embodiment. The output unit 195 outputs, for example, the judgment result of the judgment unit 190 to the watching management device 300 via the communication unit 110 and the first terminal device 200. The alarm unit 180, the judgment unit 190, and the output unit 195 are provided on only one of the left foot and the right foot, or on both feet. The watching management device 300 outputs the received determination result to the second terminal device 400.

[0070] As a modified example, the watching management device 300 may be omitted in the watching system 1A. In this case, the watching device 100 and the first terminal device 200 are connected by short-range communication such as Bluetooth. The first terminal device 200 and the second terminal device 400 are connected via a network NW such as a wireless LAN. The watching device 100 judges a fall or the like, and transmits the judgment result to the first terminal device 200. The first terminal device 200 outputs the received judgment result to the second terminal device 400.

[0071] According to the above-described second embodiment, the watching system 1A can determine whether the user has fallen or has heat stroke using only the watching device 100, and the processing can be simplified.

[0072] The above describes the form for carrying out the present invention using an embodiment, but the present invention is not limited to such an embodiment, and various modifications and substitutions can be made within the scope that does not deviate from the gist of the present invention.
