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 a first embodiment of the present invention. The abnormality detection system 1 includes a mobile terminal 10 and an electronic device 20. The user who uses the mobile terminal 10 and the electronic device 20 is the "user U" shown in FIG. The user U is, for example, a person (for example, an elderly person) who needs daily safety confirmation. The abnormality detection system 1 detects an abnormality that has occurred in the space where the electronic device 20 is arranged by the cooperation between the electronic device 20 and the mobile terminal 10. In the present embodiment, the abnormality detection system 1 detects an abnormality related to the user U.

Pairing is a process of establishing a wireless communication path, for example, according to Bluetooth®. A standard other than Bluetooth (for example, Wi-Fi (registered trademark)) may be adopted, but when the mobile terminal 10 and the electronic device 20 are in close proximity to each other, a wireless communication path is established. Further, 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 that the mobile terminal 10 may communicate with via the network NW.

The electronic device 20 is usually arranged in an upright position as shown in FIG. Such an electronic device 20 may tip over when an object comes into contact with it. For example, it is possible that the electronic device 20 may be overturned without the user U being aware of it due to the poor physical condition of the user U. Therefore, the abnormality detection system 1 detects the occurrence of an abnormality in a predetermined space based on the presence or absence of a fall of the electronic device 20.

FIG. 2 is a diagram for explaining the situation in the space where the electronic device 20 is arranged. There are "Pattern 0", "Pattern 1", "Pattern 2", and "Pattern 3" as the types of situations in the space.
“Pattern 0” indicates a case where no particular abnormality has occurred in the space, that is, a case where it is normal. In this case, the electronic device 20 is in a standing state. On the other hand, "Pattern 1", "Pattern 2", and "Pattern 3" indicate a case where the electronic device 20 has fallen. In "Pattern 1", the electronic device 20 and the mobile terminal 10 are not paired. In this case, the mobile terminal 10 may not exist near the electronic device 20, and the user U may 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, the mobile terminal 10 may be near the electronic device 20, and the user U may also be 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 which of the "pattern 0", "pattern 1", "pattern 2", and "pattern 3" situations.

FIG. 4 is a block diagram showing an example of the functional configuration 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 detects the presence or absence of a fall of the electronic device 20 by using the acceleration sensor 251 included in the input device 25. The acceleration sensor 251 is a sensor for measuring the position or posture of the electronic device 20. The acceleration sensor 251 is, for example, a three-axis acceleration sensor. The fall 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 the 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 state data transmission unit 212 detects that the electronic device 20 has fallen, the short-range wireless communication unit 241 included in the communication device 24 is used to provide state data indicating that fact to the mobile terminal. Send to 10. The short-range wireless communication unit 241 is a communication unit that communicates with the mobile terminal 10 using an 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 by 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.
The pairing of the mobile terminal 10 and the electronic device 20 may be performed when the mobile terminal 10 and the electronic device 20 are close to each other within a distance capable of short-range wireless communication, or may be performed when the user U is operated. ..

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 or not 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 operation unit 151 of the input device 15 and whether or not the mobile terminal 10 is in a stationary state. The operation unit 151 is an operation means operated by the 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 by the acceleration sensor 152. The acceleration sensor 152 is a sensor for measuring the position or posture of the mobile terminal 10. The acceleration sensor 152 is, for example, a three-axis acceleration sensor.

The notification unit 112 sets the notification destination to the user U or a specific user (hereinafter referred to as "specific user"). The specific user is, for example, a relative of the user U or a friend. The notification unit 112 notifies the user U by, for example, outputting voice using the voice 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 or a text message. Further, the notification unit 112 notifies a specific user by communicating with the external terminal 30 by 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 communicates via the network NW.

FIG. 5 is a flowchart showing a process executed by the electronic device 20.
First, the state detection unit 211 detects whether or not 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 step S2, the state detection unit 211 returns to the process of step S1. When the situation in the space is "Pattern 0" described with reference to FIG. 2, this processing flow is performed. If the electronic device 20 has not fallen, the abnormality detection system 1 does not detect the occurrence of an abnormality.

When the state detection unit 211 detects that the electronic device 20 has fallen, it determines "YES" in step S2. Next, the state data transmission unit 212 determines whether or not the electronic device 20 and the mobile terminal 10 are being paired (step S3). If it is determined as "NO" in step S3, the state data transmission 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 from the time of the fall, the state data shall be transmitted to the mobile terminal 10. .. If the state data transmission unit 212 has not timed out, it determines "NO" in step S4 and returns to the process of step S3.

If the electronic device 20 and the mobile terminal 10 are not paired within a predetermined time and a time-out occurs, the state data transmission unit 212 determines “YES” in step S4. As a result, the process of FIG. 5 is completed. As a situation where a time-out occurs, there is a case of "Pattern 1" described with reference to FIG. This is because if the mobile terminal 10 does not exist near the electronic device 20 due to the absence of the user U or the like, a timeout occurs without pairing. In such a case, even if the electronic device 20 falls, there is a relatively high possibility that the fall is not 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 time-out occurs without pairing with the mobile terminal 10, the abnormality detection system 1 does not detect the occurrence of the abnormality.

When the state data transmission unit 212 determines in step S3 that the pairing with the mobile terminal 10 is in progress (step S3; YES), the state data transmission unit 212 transmits the state data indicating that the electronic device 20 has fallen to the mobile terminal 10. (Step S5). When the situation in the space is the "pattern 2" or the "pattern 3" described with reference to FIG. 2, this processing flow is performed. When the electronic device 20 and the mobile terminal 10 are being paired, the user U may be near the electronic device 20. Therefore, there is a possibility that the electronic device 20 has 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 the process described below.

FIG. 6 is a flowchart showing a process executed by the mobile terminal 10.
The state data acquisition unit 111 acquires (receives) the state data transmitted by the electronic device 20 (step S11). Next, the notification unit 112 determines whether or not the mobile terminal 10 is not operated (step S12). No operation means a state in which an operation using the operation unit 151 is not performed. If "YES" is determined 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 means a state in which the mobile terminal 10 is stationary (including a state in which the mobile terminal 10 can be regarded as stationary). For example, when the temporal change of the acceleration measured by the acceleration sensor 152 is zero or almost zero, the notification unit 112 determines that the state is stationary.

If it is determined as "YES" in step S13, the notification unit 112 determines whether or not the no-operation and the stationary state has continued for a predetermined time (step S14). The "predetermined time" is a predetermined length of time, for example, 20 seconds. If it is determined that the operation using the operation unit 151 has been performed before the predetermined time elapses (step S12; NO), or if it is determined that the mobile terminal 10 is no longer in a stationary state (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 returns to the original posture (step S15). Upon receiving this notification, the user U returns the electronic device 20 to its original posture. When the situation in the space is the "pattern 2" described in FIG. 2, this is the flow of processing. If the mobile terminal 10 is in use, it is highly possible that the user U is using the mobile terminal 10. Therefore, it is unlikely that any abnormality has occurred in the user U. Therefore, even if the electronic device 20 falls, the abnormality detection system 1 does not detect the occurrence of the abnormality when the mobile terminal 10 is in use.

When the state data transmission unit 212 detects that the electronic device 20 has been set up again by the state detection unit 211, the state data transmission unit 212 may transmit the 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 as "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 is the flow of processing. When the electronic device 20 falls, the mobile terminal 10 exists near the electronic device 20 and the electronic device 20 is not in use. For example, the user U falls down due to poor physical condition and the electronic device 20 is knocked down. This is because there is a possibility that it has been done.

In step S16, the notification unit 112 notifies, for example, that an abnormality has occurred by a voice message or the like when receiving an incoming call from the external terminal 30. The voice message indicates, for example, the message "Mr. ## may have an abnormality." Alternatively, the notification unit 112 may actively notify the specific user that an abnormality has occurred. Here, "actively notifying" means notifying even if there is no request for communication from the external terminal 30 such as an incoming call. The notification unit 112 makes a call to the external terminal 30, for example, and reproduces a voice message when there is a response from the external terminal 30. Instead of the voice message, the notification unit 112 may send an electronic message (for example, an electronic mail) to the external terminal 30. The specific user who receives 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 an 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 has a different notification content or notification destination based on the state of the own mobile terminal (whether or not it is in use in this embodiment). Specifically, even if the electronic device 20 falls, the mobile terminal 10 notifies the user U if the own mobile terminal is in use, and notifies a specific user otherwise. As a result, according to the abnormality detection system 1, it is possible to notify that an abnormality has occurred at the notification destination and the notification content according 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 presence or absence of a fall of the electronic device 20 and the environment around the electronic device 20. 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 represented by the same reference numerals as those in the first embodiment, and the corresponding elements are represented by the end of the reference numerals. Is indicated by adding "A".

FIG. 7 is a block diagram showing an example of the functional configuration of the processor 11A of the mobile terminal 10 and the processor 21A of the electronic device 20 according to the present embodiment. Hereinafter, the differences from the processors 11 and 21 will be mainly described.
The processor 21A includes a state detection unit 211, a state data transmission unit 212, and an environment information transmission unit 213. The environmental information transmission unit 213 transmits environmental 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 environment sensor 252 is a sensor that measures environmental information indicating the environment around the electronic device 20. In the present embodiment, the environment sensor 252 includes a temperature sensor for measuring temperature and a humidity sensor for measuring humidity. The environmental information transmission unit 213 transmits the environmental information to the mobile terminal 10 by 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 environmental information acquisition unit 113 acquires environmental information via a communication path established between the mobile terminal 10 and the electronic device 20. Specifically, the environmental information acquisition unit 113 acquires environmental information using the short-range wireless communication unit 141.

The notification unit 112A notifies 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 the present embodiment, the environmental information is used to determine whether or not 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 showing a process executed by the electronic device 20. In the following description, the steps in which the same processing as that of the first embodiment described above is executed are designated by the same reference numerals as those of the first embodiment.
The state detection unit 211 detects whether or not 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 it is determined as "YES" in step S2, the state data transmission unit 212 determines whether or not the electronic device 20 and the mobile terminal 10 are being paired (step S3). The process when "NO" is determined in step S3 is the same as that of the first embodiment described above.

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

FIG. 9 is a flowchart showing a process executed by the mobile terminal 10.
The state data acquisition unit 111 acquires (receives) state data from the electronic device 20 (step S11). Next, the environmental information acquisition unit 113 acquires (receives) environmental 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 obtained. , It is determined whether or not the predetermined environmental condition is satisfied (step S18). Here, as a condition for easily developing heat stroke, it is an environmental condition that the temperature and the humidity are each equal to or higher than the threshold value.

If it is determined as "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 has fallen, the mobile terminal 10 has not been operated, and the stationary state has continued for a predetermined time, and if the environmental conditions that are likely to cause heat stroke are satisfied, the user U may have an abnormality such as poor physical condition. There is sex. Therefore, the notification unit 112A makes a call to the external terminal 30, and when there is a response from the external terminal 30, the notification unit 112A reproduces a voice message. The voice message indicates, for example, the message "Mr. ## may have an abnormality, so please confirm your safety as soon as possible."

If it is determined as "NO" in step S18, the notification 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 less likely that the user U has an abnormality such as poor physical condition than when the environmental conditions are satisfied. Therefore, when the notification unit 112A receives an incoming call from the external terminal 30, it notifies the external terminal 30 of a voice message "There is a possibility that an abnormality has occurred in Mr. ##."
Further, the notification unit 112A may change the notification destination based on whether or not 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 more accurately detect the occurrence of an abnormality in the space in which the electronic device 20 is arranged.

[Modification example]
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 example 1)
The environmental conditions described in the second embodiment described above are not limited to the conditions indicating an environment in which heat stroke is likely to occur. For example, environmental conditions may indicate that an earthquake has occurred or that a gas leak has occurred. The environmental information measured by the environmental sensor 252 also differs 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 accuracy of detecting the occurrence of an abnormality will be improved as compared with the case where the occurrence of an abnormality is detected only by the presence or absence of a fall of the electronic device 20. In addition, environmental information such as the occurrence of an earthquake can be acquired without using the environmental sensor 252. The environmental information acquisition unit 113 may acquire data indicating an earthquake early warning as environmental information indicating that an earthquake has occurred via the network NW.

(Modification 2)
The anomaly detection system may include a plurality of electronic devices 20 used by the user U. In this case, 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 if only one electronic device 20 falls, it may be accidental, but if a plurality of electronic devices 20 fall, it is highly probable that some abnormality has occurred. Therefore, the notification unit 112 (or the notification unit 112A; the same applies hereinafter) notifies that an abnormality has occurred according to the number of detected falls of the electronic device 20. For example, when the number of the electronic devices 20 that have fallen is less than the threshold value, the notification unit 112 notifies that an abnormality has occurred when receiving an incoming call from the external terminal 30. On the other hand, when the number of the electronic devices 20 that have fallen is equal to or greater than the threshold value, the notification unit 112 actively notifies that an abnormality has occurred.

(Modification example 3)
If the electronic device 20 remains toppled 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, the notification unit 112 may give another notification. .. The notification unit 112, for example, gives another notification after a predetermined time (for example, 20 minutes) has elapsed from the first notification. This re-notification may be given 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 has performed the first notification when receiving an incoming call from the external terminal 30, the notification unit 112 actively performs the re-notification. Further, the notification unit 112 may change the content of the message.
