Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram showing an overall configuration of an abnormality detection system 1 according to the first embodiment of the present invention. The abnormality detection system 1 includes a mobile terminal 10 and an electronic device 20. A user who uses the mobile terminal 10 and the electronic device 20 is a “user U” illustrated in FIG. 1. The user U is, for example, a person (for example, an elderly person) who needs daily safety confirmation. In the abnormality detection system 1, an abnormality that occurs in the space where the electronic device 20 is arranged is detected by cooperation between the electronic device 20 and the mobile terminal 10. In this embodiment, the abnormality detection system 1 detects an abnormality related to the user U.

  The portable terminal 10 is a portable communication terminal device. Here, the mobile terminal 10 is a smartphone. However, the mobile terminal 10 may be a mobile phone such as a feature phone or a tablet computer. The mobile terminal 10 has a function of pairing with the electronic device 20 and communicating (wireless communication) with the electronic device 20. Pairing is a process of establishing a wireless communication path according to, for example, Bluetooth (registered trademark). Standards other than Bluetooth (for example, Wi-Fi (registered trademark)) may be adopted, but a wireless communication path is established when the mobile terminal 10 and the electronic device 20 are close to each other. The mobile terminal 10 has a function of communicating with the network NW. The network NW includes a wireless communication network. The external terminal 30 shown in FIG. 1 is an external communication terminal device with which the mobile terminal 10 may communicate via the network NW.

  The electronic device 20 is arranged in a predetermined space where the user U may stay. As this space, for example, there is a room at the home of the user U. The electronic device 20 has a function of pairing with the mobile terminal 10 and communicating with the mobile terminal 10. The electronic device 20 is formed in a substantially cylindrical shape in this embodiment. Although the external appearance of the electronic device 20 may not be as shown in FIG. 1, it is a relatively small and lightweight electronic device. The electronic device 20 is usually arranged in a standing state as shown in FIG. Such an electronic device 20 may fall down when an object contacts. For example, due to poor physical condition of the user U, the electronic device 20 may be overturned before the user U is aware of it. Therefore, the abnormality detection system 1 detects the occurrence of an abnormality in a predetermined space based on whether or not the electronic device 20 is overturned.

FIG. 2 is a diagram illustrating a situation in the space where the electronic device 20 is arranged. There are “pattern 0”, “pattern 1”, “pattern 2”, and “pattern 3” as types of situations in the space.
“Pattern 0” indicates a case where no abnormality has occurred in the space, that is, a normal state. In this case, the electronic device 20 is standing. On the other hand, “Pattern 1”, “Pattern 2”, and “Pattern 3” indicate cases where the electronic device 20 falls. In “Pattern 1”, the electronic device 20 and the mobile terminal 10 are not paired. In this case, there is a possibility that the mobile terminal 10 does not exist near the electronic device 20 and the user U does not exist near the electronic device 20. In “Pattern 2” and “Pattern 3”, the electronic device 20 and the mobile terminal 10 are paired. In these cases, there is a possibility that the mobile terminal 10 is present near the electronic device 20 and the user U is also present near the electronic device 20. In the case of “Pattern 2”, the user U is using the mobile terminal 10, but in the case of “Pattern 3”, the user U is not using the mobile terminal 10.
The abnormality detection system 1 detects the occurrence of an abnormality based on the status of “Pattern 0”, “Pattern 1”, “Pattern 2”, and “Pattern 3”.

(Registered trademark) disk, smart card, flash memory (for example, card, stick, key drive), floppy (registered trademark) disk, magnetic strip, and the like. The storage 13 may be called an auxiliary storage device. The above-described storage medium may be, for example, a database including the memory 12 and / or the storage 13, a server, or other suitable medium.

  The communication device 14 is hardware (transmission / reception device) for performing communication between computers, and is also referred to as a communication module, for example.

The input device 15 is an input device (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, or the like) that accepts an external input. The output device 16 is an output device (for example, a display, a speaker, an LED lamp, etc.) that performs output to the outside.
Note that the input device 15 and the output device 16 may have an integrated configuration (for example, a touch panel).

  The devices such as the processor 11 and the memory 12 are connected by a bus 17 for communicating information. The bus 17 may be composed of a single bus or may be composed of different buses between devices.

The mobile terminal 10 includes hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA). A part or all of each functional block may be realized by the hardware. For example, the processor 11 may be implemented by at least one of these hardware.
Each function in the portable terminal 10 is read by a predetermined software (program) loaded on hardware such as the processor 11 and the memory 12, so that the processor 11 performs an operation and performs communication by the communication device 14, the memory 12, and the storage 13. This is realized by controlling the reading and / or writing of data.

The configuration may be the same as or different from the configuration read as the input device 25, the output device 26, and the bus 27.

FIG. 4 is a block diagram illustrating an example of functional configurations of the processor 11 of the mobile terminal 10 and the processor 21 of the electronic device 20.
The processor 21 includes a state detection unit 211 and a state data transmission unit 212. The state detection unit 211 detects the state of the electronic device 20. Specifically, the state detection unit 211 uses the acceleration sensor 251 included in the input device 25 to detect whether the electronic device 20 has fallen. The acceleration sensor 251 is a sensor for measuring the position or orientation of the electronic device 20. The acceleration sensor 251 is, for example, a triaxial acceleration sensor. The overturn of the electronic device 20 is an example of a change in the position or posture of the electronic device 20.

  The state data transmission unit 212 transmits state data indicating the state of the electronic device 20 detected by the state detection unit 211 to the mobile terminal 10. Specifically, when the electronic device 20 is detected to fall, the state data transmission unit 212 uses the short-range wireless communication unit 241 included in the communication device 24 to transmit the state data indicating that to the portable terminal. 10 to send. The short-range wireless communication unit 241 is a communication unit that communicates with the mobile terminal 10 using the established wireless communication path when the electronic device 20 and the mobile terminal 10 are paired.

The processor 11 includes a state data acquisition unit 111 and a notification unit 112. The state data acquisition unit 111 acquires state data via a communication path established between the mobile terminal 10 and the electronic device 20. Specifically, the state data acquisition unit 111 acquires this state data using the short-range wireless communication unit 141 included in the communication device 14. The short-range wireless communication unit 141 is a communication unit that communicates with the electronic device 20 using the established wireless communication path when the mobile terminal 10 and the electronic device 20 are paired.
Note that the pairing between the mobile terminal 10 and the electronic device 20 may be performed when the mobile terminal 10 and the electronic device 20 approach each other within a distance where short-range wireless communication is possible, or may be performed when the user U operates. .

  The notification unit 112 notifies that an abnormality has occurred based on the change in the state of the electronic device 20 indicated by the state data and the state of the mobile terminal 10. The change in the state of the electronic device 20 indicates that the electronic device 20 has fallen as described above. The state of the mobile terminal 10 indicates whether the mobile terminal 10 is in use. Whether or not the mobile terminal 10 is in use is determined based on the operation status of the input device 15 with respect to the operation unit 151 and whether or not the mobile terminal 10 is stationary. The operation unit 151 is an operation unit operated by a user. The operation unit 151 includes, for example, a physical key or a touch sensor. Whether or not the mobile terminal 10 is in a stationary state is determined based on the acceleration measured using the acceleration sensor 152. The acceleration sensor 152 is a sensor for measuring the position or orientation of the mobile terminal 10. The acceleration sensor 152 is a triaxial acceleration sensor, for example.

  The notification unit 112 uses the user U or a specific user (hereinafter referred to as “specific user”) as a notification destination. The specific user is, for example, a person in the relatives of the user U or a friend. The notification unit 112 performs notification to the user U, for example, by outputting sound using the sound output unit 161 included in the output device 16 or displaying information using the display unit 162. The audio output unit 161 includes, for example, a speaker and outputs audio. The display unit 162 includes, for example, a display and displays an image and a text message. Further, the notification unit 112 notifies the specific user by communicating with the external terminal 30 using the network communication unit 142 included in the communication device 14. The network communication unit 142 includes, for example, a wireless communication circuit and an antenna, and performs communication via the network NW.

FIG. 5 is a flowchart illustrating processing executed by the electronic device 20.
First, the state detection unit 211 detects whether the electronic device 20 has fallen (step S1). Next, the state detection unit 211 determines whether or not the electronic device 20 has fallen (step S2). If “NO” is determined in the step S2, the state detection unit 211 returns to the process of the step S1. When the situation in the space is “pattern 0” described with reference to FIG. When the electronic device 20 is not overturned, the abnormality detection system 1 does not detect the occurrence of abnormality.

  If the state detection unit 211 detects that the electronic device 20 has fallen, the state detection unit 211 determines “YES” in step S2. Next, the state data transmission unit 212 determines whether the electronic device 20 and the mobile terminal 10 are pairing (step S3). If “NO” is determined in the step S3, the state data transmitting unit 212 determines whether or not a timeout has occurred (step S4). In the electronic device 20, when the own device falls, if pairing with the mobile terminal 10 is performed within a predetermined time after the fall, state data is transmitted to the mobile terminal 10. . If the timeout has not occurred, the state data transmission unit 212 determines “NO” in step S4, and returns to the process in step S3.

  If the status data transmission unit 212 does not pair the electronic device 20 and the mobile terminal 10 within a predetermined time and times out, it determines “YES” in step S4. Thereby, the process of FIG. 5 is completed. As a situation where a timeout occurs, there is the case of “pattern 1” described in FIG. This is because if the mobile terminal 10 does not exist near the electronic device 20 due to reasons such as the absence of the user U, timeout occurs without pairing. In such a case, even if the electronic device 20 falls, there is a relatively high possibility that it is not a fall caused by the user U. For example, the electronic device 20 may have accidentally fallen due to the occurrence of an earthquake. Therefore, even if the electronic device 20 falls, if the timeout occurs without pairing with the mobile terminal 10, the abnormality detection system 1 does not detect the occurrence of the abnormality.

If the state data transmission unit 212 determines that the pairing with the mobile terminal 10 is being performed in Step S3 (Step S3; YES), the state data transmission unit 212 transmits state data indicating that the electronic device 20 has fallen to the mobile terminal 10. (Step S5). If the situation in the space is “Pattern 2” or “Pattern 3” described with reference to FIG. When the electronic device 20 and the mobile terminal 10 are being paired, the user U may exist near the electronic device 20. Therefore, the electronic device 20 may have fallen due to the user U.
When the state data is transmitted from the electronic device 20 to the mobile terminal 10, the mobile terminal 10 executes processing described below.

FIG. 6 is a flowchart illustrating processing executed by the mobile terminal 10.
The status data acquisition unit 111 acquires (receives) status data transmitted by the electronic device 20 (step S11). Next, the notification unit 112 determines whether or not the portable terminal 10 is not operated (step S12). No operation means a state in which an operation using the operation unit 151 is not performed. When determining “YES” in step S12, the notification unit 112 determines whether or not the mobile terminal 10 is in a stationary state (step S13). The stationary state refers to a state in which the mobile terminal 10 is stationary (including a state that can be regarded as stationary). For example, when the temporal change in the acceleration measured by the acceleration sensor 152 is zero or almost zero, the notification unit 112 determines that it is in a stationary state.

  If it is determined “YES” in step S13, the notification unit 112 determines whether no operation and a stationary state have continued for a predetermined time (step S14). The “predetermined time” is a predetermined length of time, for example, 20 seconds. When it is determined that an operation using the operation unit 151 has been performed before the predetermined time has elapsed (step S12; NO), or when it is determined that the mobile terminal 10 is no longer stationary (step S13; NO) The notification unit 112 proceeds to the process of step S15. Specifically, the notification unit 112 notifies the user U that the electronic device 20 is to be returned to the original posture (step S15). Upon receiving this notification, the user U returns the electronic device 20 to the original posture. When the situation in the space is “Pattern 2” described with reference to FIG. If the mobile terminal 10 is in use, there is a high possibility that the user U is using the mobile terminal 10. Therefore, it is unlikely that some abnormality has occurred with respect to the user U. Therefore, even when the electronic device 20 falls, the abnormality detection system 1 does not detect the occurrence of an abnormality when the mobile terminal 10 is in use.

  When the state detection unit 211 detects that the electronic device 20 has been stood up again, the state data transmission unit 212 may transmit state data indicating that fact to the mobile terminal 10. In this case, the notification unit 112 stops the notification in step S15 when the state data is acquired by the state data acquisition unit 111.

  If it is determined “YES” in step S14, the notification unit 112 notifies the specific user that an abnormality has occurred (step S16). When the situation in the space is “Pattern 3”, this processing flow is performed. When the electronic device 20 falls, as a situation in which the mobile terminal 10 is present near the electronic device 20 and the electronic device 20 is not in use, for example, the user U falls due to poor physical condition and falls down the electronic device 20 This is because there is a possibility that it has been.

  In step S16, for example, when the notification unit 112 receives an incoming call from the external terminal 30, the notification unit 112 notifies that an abnormality has occurred by a voice message or the like. The voice message indicates, for example, a message “There is a possibility that an abnormality has occurred in Mr. ##”. Alternatively, the notification unit 112 may actively notify a specific user that an abnormality has occurred. Here, actively notifying means that notification is made even when there is no communication request from the external terminal 30 such as an incoming call. For example, the notification unit 112 transmits a call to the external terminal 30 and reproduces a voice message when a response is received from the external terminal 30. Instead of the voice message, the notification unit 112 may transmit an electronic message (for example, an electronic mail) to the external terminal 30. The specific user who has received the notification that the abnormality has occurred takes measures such as visiting the home of the user U.

  According to the abnormality detection system 1 of the embodiment described above, the occurrence of abnormality in the space in which the electronic device 20 is arranged is accurately detected based on the change in the state of the electronic device 20 and the state of the mobile terminal 10. be able to. Further, the mobile terminal 10 changes the notification content or the notification destination based on the state of the mobile terminal (in the present embodiment, whether it is in use). Specifically, even when the electronic device 20 falls, the mobile terminal 10 notifies the user U when the self-portable terminal is in use, and notifies the specific user otherwise. Thereby, according to the abnormality detection system 1, notification that an abnormality has occurred can be performed with the notification destination and notification content corresponding to the situation at that time.

[Second Embodiment]
The abnormality detection system of the second embodiment detects the occurrence of an abnormality based on the surrounding environment of the electronic device 20 in addition to the presence or absence of the electronic device 20 falling. In the following description, among the elements of the mobile terminal 10 and the electronic device 20, the same elements as those in the first embodiment described above are denoted by the same reference numerals as those in the first embodiment, and the corresponding elements are suffixed with reference numerals. Is represented with “A”.

FIG. 7 is a block diagram illustrating an example of functional configurations of the processor 11A of the mobile terminal 10 and the processor 21A of the electronic device 20 according to the present embodiment. Hereinafter, a description will be given focusing on differences from the processors 11 and 21.
The processor 21 </ b> A includes a state detection unit 211, a state data transmission unit 212, and an environment information transmission unit 213. The environment information transmission unit 213 transmits environment information indicating the environment around the electronic device 20 to the mobile terminal 10. The environment around the electronic device 20 is measured by the environment sensor 252 included in the input device 25A. The environmental sensor 252 is a sensor that measures environmental information indicating the environment around the electronic device 20. In the present embodiment, the environmental sensor 252 includes a temperature sensor that measures temperature and a humidity sensor that measures humidity. The environment information transmission unit 213 transmits the environment information to the mobile terminal 10 using the short-range wireless communication unit 241.

  The processor 11A includes a state data acquisition unit 111, an environment information acquisition unit 113, and a notification unit 112A. The environment information acquisition unit 113 acquires environment information via a communication path established between the mobile terminal 10 and the electronic device 20. Specifically, the environment information acquisition unit 113 acquires environment information using the short-range wireless communication unit 141.

  The notification unit 112A performs notification that an abnormality has occurred based on the change in the state of the electronic device 20 indicated by the state data, the environmental information, and the state of the mobile terminal 10. In this embodiment, the environmental information is used to determine whether the environment around the electronic device 20 satisfies a condition that can cause an abnormality in the human body (hereinafter referred to as “environmental condition”). Generally, when the temperature or humidity around the electronic device 20 is extremely high, heat stroke is likely to occur.

FIG. 8 is a flowchart illustrating processing executed by the electronic device 20. In the following description, steps in which the same processing as that in the first embodiment described above is executed are denoted by the same reference numerals as in the first embodiment.
The state detection unit 211 detects whether the electronic device 20 has fallen (step S1). Next, the state detection unit 211 determines whether or not the electronic device 20 has fallen (step S2). If “YES” is determined in the step S2, the state data transmitting unit 212 determines whether or not the electronic device 20 and the mobile terminal 10 are being paired (step S3). The processing in the case where “NO” is determined in step S3 is the same as that in the first embodiment described above.

If “YES” is determined in step S3, the state data transmission unit 212 transmits state data indicating that the electronic device 20 has fallen to the portable terminal 10 (step S5). Furthermore, the environment information transmission unit 213 transmits the environment information to the mobile terminal 10 (step S6). This environmental information indicates the environment when the electronic device 20 falls, for example.
When the state data and the environment information are transmitted from the electronic device 20 to the mobile terminal 10, the mobile terminal 10 executes processing described below.

FIG. 9 is a flowchart illustrating processing executed by the mobile terminal 10.
The status data acquisition unit 111 acquires (receives) status data from the electronic device 20 (step S11). Next, the environment information acquisition unit 113 acquires (receives) environment information from the electronic device 20 (step S17). Next, when the notification unit 112A determines that the mobile terminal 10 has not been operated and the stationary state has continued for a predetermined time (steps S12, S13, S14; YES), the environmental information acquired in step S17 is stored. It is determined whether or not a predetermined environmental condition is satisfied (step S18). Here, the environmental condition is that the temperature and the humidity are each equal to or higher than the threshold value as a condition for causing heat stroke.

  If it is determined “YES” in step S18, the notification unit 112A actively notifies the specific user that an abnormality has occurred (step S19). When the electronic device 20 falls down, the mobile terminal 10 is not operated, and the stationary state continues for a predetermined time, the user U may have an abnormality such as a poor physical condition when the environmental condition that is likely to cause heat stroke is satisfied. There is sex. Therefore, the notification unit 112A transmits a call to the external terminal 30 and reproduces a voice message when a response is received from the external terminal 30. The voice message indicates, for example, a message “There is a possibility that an abnormality has occurred in Mr. ## so please confirm safety as soon as possible”.

If “NO” is determined in the step S18, the notifying unit 112A notifies that an abnormality has occurred when receiving an incoming call from the external terminal 30 (step S20). When the environmental information does not satisfy the environmental conditions, it is considered that the possibility that an abnormality such as poor physical condition has occurred in the user U is lower than when the environmental conditions are satisfied. Therefore, when the notification unit 112A accepts an incoming call from the external terminal 30, the notification unit 112A notifies the external terminal 30 of a voice message “There is a possibility that an abnormality has occurred in ##”.
Furthermore, the notification unit 112A may change the notification destination based on whether the environmental information satisfies the environmental condition.

  As described above, the environmental information indicating the environment around the electronic device 20 can be useful information for detecting the occurrence of an abnormality. Therefore, according to the abnormality detection system of the present embodiment, it is possible to detect an abnormality with higher accuracy when an abnormality occurs in the space in which the electronic device 20 is disposed.

[Modification]
The present invention may be implemented in a form different from the above-described embodiment. Moreover, you may combine each of the modification shown below.

(Modification 1)
The environmental conditions described in the above-described second embodiment are not limited to conditions indicating an environment in which heat stroke is likely to occur. For example, the environmental condition may indicate that an earthquake has occurred or that a gas leak has occurred. The environmental information measured by the environmental sensor 252 varies depending on the environmental conditions to be adopted. When the occurrence of an earthquake is an environmental condition, the environmental sensor 252 measures the occurrence of vibration. When the environmental condition is that a gas leak has occurred, the environmental sensor 252 measures the amount of gas components in the air. Even when these environmental conditions are adopted, it can be expected that the detection accuracy of the abnormality is improved as compared with the case where the occurrence of the abnormality is detected only by whether the electronic device 20 is overturned. In addition, environmental information such as the occurrence of an earthquake can be acquired without using the environmental sensor 252. The environment information acquisition unit 113 may acquire data indicating the earthquake early warning via the network NW as environment information indicating that an earthquake has occurred.

(Modification 2)
The abnormality detection system may include a plurality of electronic devices 20 used by the user U. This is because the number of electronic devices 20 that have fallen at the same time is also an index for grasping the abnormality that has occurred in the space. This is because when only one electronic device 20 falls, it may be accidental, but when a plurality of electronic devices 20 falls, it is highly likely that some abnormality has occurred. Therefore, the notification unit 112 (or the notification unit 112A; the same applies hereinafter) performs notification that an abnormality has occurred according to the number of detected overturns of the electronic device 20. For example, when the number of electronic devices 20 that have fallen is less than the threshold, the notification unit 112 notifies that an abnormality has occurred when an incoming call from the external terminal 30 is received. On the other hand, when the number of the electronic devices 20 that have fallen is equal to or greater than the threshold, the notification unit 112 actively notifies that an abnormality has occurred.

(Modification 3)
The notification unit 112 may perform another notification when the electronic device 20 remains overturned even after a predetermined period has elapsed from the acquisition of the state data from the electronic device 20 or the notification of the occurrence of an abnormality. . For example, the notification unit 112 performs another notification after a predetermined time (for example, 20 minutes) has passed since the first notification. This re-notification may be performed any number of times.

  In this re-notification, the notification unit 112 may change the notification content or the notification destination from the first notification. For example, when the notification unit 112 performs the first notification when an incoming call from the external terminal 30 is received, the notification unit 112 actively performs the notification again. Further, the notification unit 112 may change the content of the message.

(Modification 4)
When it is determined that an abnormality has occurred, the mobile terminal 10 may perform recording and notify the specific user of the occurrence of the abnormality based on audio data indicating the recorded voice. If the mobile terminal 10 does not return to its original posture even after a predetermined time (for example, 15 minutes) has passed since the electronic device 20 falls, this audio data is used when notifying the occurrence of an abnormality to a specific user. Play.
In addition, although the case where the portable terminal 10 recorded here was demonstrated, the electronic device 20 may record and may transmit audio | voice data to the portable terminal 10. FIG.

(Modification 5)
The “state of the electronic device” of the present invention is not limited to whether or not the electronic device is overturned. “Electronic device state” may indicate a position or posture state of the electronic device other than a fall. For example, the movement or rolling of the electronic device is also included in the “electronic device state”. The change in the position or posture of the electronic device has both the possibility that the cause is artificial and the possibility that it is not. Therefore, detecting the occurrence of an abnormality based on a change in the position or orientation of the electronic device can contribute to improving the accuracy of the detection.

(Modification 6)
The “state of the electronic device” of the present invention may be the state of the environment where the electronic device is placed. In this case, when there is a relatively large environmental change (for example, a rapid temperature increase or humidity increase) as the state data, the electronic device transmits state data indicating that fact to the mobile terminal. If there is a relatively large change in the environment in the space in which the electronic device 20 is placed based on the state data, the mobile terminal has an abnormality based on the change in the environment and the state of the mobile terminal. Notify that it has occurred.

(Modification 7)
The mobile terminal 10 may have some of the functions that the electronic device 20 has in the above-described embodiment. Alternatively, the electronic device 20 may have some of the functions that the mobile terminal 10 has.
For example, the mobile terminal 10 may have the environment sensor described in the second embodiment. In this case, the environment information indicates the environment around the mobile terminal 10. If the mobile terminal 10 and the electronic device 20 are close to each other within a pairable distance, it can be considered that the same result is obtained regardless of which environment information is measured. Therefore, the subject that measures the environmental information is not particularly limited. In addition, the electronic device 20 carries a state notification indicating an abnormality occurrence state based on a change in the state of its own device (whether it has fallen or the like) and a state of the portable terminal 10 (no operation state, stationary state). You may transmit to the terminal 10. The notification unit of the mobile terminal 10 notifies that an abnormality has occurred based on this state notification.

(Modification 8)
A part of the configuration or operation described in the above-described embodiment may be omitted. For example, whether or not the mobile terminal 10 is in use may be determined based on one of the operation status of the mobile terminal 10 and whether or not the mobile terminal 10 is stationary.
