Description

  The present invention relates to an electronic device, an information processing system, an emergency information transmission system, and the like.

  In an emergency or emergency, it is very effective to measure the location at that time with GPS (Global Positioning System) and inform it along with the situation. Mobile phones with GPS and small GPS dedicated devices have already been widely used, and these devices can be said to be very suitable devices for emergency information transmission.

  However, mobile phones and small dedicated devices can be lost and can be easily turned off by a third party, so that location confirmation and emergency response are insufficient. On the other hand, wristwatches with built-in GPS (band-type devices in a broad sense, wearable devices in a broad sense) are usually attached to the arms (any part of the user in a broad sense), so there is a risk of loss. Less is.

  However, the position measurement by GPS generally consumes a large amount of power for continuous positioning. In the case of a wristwatch, since it is difficult to use a large battery, it is difficult to secure power, and reliable position measurement and emergency information transmission in an emergency cannot be guaranteed.

  Patent Document 1 discloses a method of shutting off the power supply inside the device and using an external power supply in order to reliably communicate even in an emergency. However, Patent Document 1 is assumed to be applied to a large moving body such as an automobile. Therefore, various mechanisms (for example, specially shaped connectors) are required, and it is difficult to apply to a small portable device such as a wristwatch with a built-in GPS.

JP 2002-49997 A

  As described above, in an electronic device or system that transmits emergency information including position information in an emergency, from the viewpoint that the device needs to be appropriately carried by the user, a watch-type or other wearable electronic device It is preferable to use equipment.

Thereby, the electronic device which can perform emergency information transmission operation | movement by connecting with an external device is realizable.

The present invention relates to an emergency information transmission system that performs processing for acquiring position information by an information acquisition unit and performs processing for transmitting the acquired position information to an external device by a transmission processing unit.

  As a result, it is possible to realize a system that receives power supply from a given battery in an emergency state and appropriately acquires and transmits position information, and a wearable device incorporating the system.

  In another aspect of the present invention, the emergency information transmission system may be included in an attachment device attached to the wearable device.

  Thereby, the emergency information transmission system is not limited to the one included in the wearable device body, and it is possible to realize a system included in the attachment.

Example of control of main body operation and emergency information transmission operation when a dedicated battery is provided.

  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. First, the method of this embodiment will be described. In an emergency or emergency, it is very effective to measure the location at that time with a position measurement system such as GPS and notify the situation together with the situation. For example, if the weather changes suddenly when climbing, or if you are injured by sliding down a slope, the climber is at risk of life and it is difficult to move on your own. . The same applies to cases where the ship drifts offshore due to ship failure.

  Mobile phones (smartphones) that are widely used nowadays have many devices that are equipped with GPS, and if they are operable in an emergency, the location information acquired by the GPS of the mobile phone Just send it. A small dedicated device for obtaining and transmitting GPS information is also known, and the device can also be used for the above emergency use.

  In order to transmit emergency information in an emergency, the electronic device for transmitting emergency information satisfies the following two points: firstly, being carried by the user and secondly being operable. There is a need. This is because the emergency information cannot be acquired and transmitted unless these two points are satisfied. From this point of view, it cannot be said that the mobile phone or the small dedicated device can reliably transmit emergency information.

  This is because mobile phones and small dedicated devices are carried in a bag or in a clothing pocket. Therefore, there is a possibility that the device itself is lost in an emergency state where emergency information transmission is required. In the case of mountain climbing, in a situation where life is at risk, there are many cases where the luggage in the backpack or pocket is lost, for example, the climber himself and the mobile phone may slide down to different places. It is done. In addition, there is a high possibility that the small dedicated device is a device that is not used on a daily basis, and in that case, there is a possibility of forgetting to carry it in the first place (for example, leaving it at home). In addition, it is likely that a user temporarily leaves the place with a mobile phone or the like placed. In the meantime, it is possible for a third party to turn off the power of the mobile phone or the like, and in this case, emergency information transmission becomes impossible.

  On the other hand, if it is a wristwatch-type device, in a broad sense, a wearable device, since the device is worn on the user's body, the possibility of loss or operation by a third party can be reduced. . However, reliable emergency information transmission is not possible simply by mounting GPS on a wearable device. This is because the wearable device is worn by the user, and the user performs exercise and daily life while wearing the device. In order not to hinder the user's behavior, the wearable device needs to be small and light, and as a result, it is difficult to increase the battery capacity. Therefore, when the wearable device consumes the battery due to the normal operation of the wearable device (for example, the movement state information or the biological information acquisition operation), and there is an emergency state, power for position measurement and emergency information transmission does not remain. There is a fear.

  In other words, when emergency information transmission is attempted by a wearable device, reliable emergency information transmission cannot be performed unless power supply in an emergency state is taken into consideration. As an emergency power supply control, a method disclosed in Patent Document 1 is known. However, in Patent Document 1, a connector having a specific shape is used in order to realize reliable connection (or disconnection) of the battery. Since Patent Document 1 assumes a system mounted on an automobile or the like, it is possible to use a connector having a somewhat complicated structure. However, in a small and lightweight wearable device, it is not possible to add such a structure. Not easy.

  Also, various power saving methods for wearable devices are known, but these methods are mainly intended to perform a normal operation (such as a biometric information acquisition operation) of the wearable device for a long time. In other words, even if the conventional power saving method is used, if the battery is operated for a long time without charging, the remaining battery level is reduced to the extent that emergency information cannot be transmitted. Operation is not guaranteed.

  In addition, the emergency state in the present embodiment is not rare, and has such a frequency that it may not last forever. Therefore, there are very few opportunities to perform emergency information transmission, and it is considered that the communication time is not so necessary as compared with general communication. For example, a position measuring device using GPS generally measures a number of times in order to improve the position accuracy, or measures for a long time in order to take a position log. In addition, although it is often measured intermittently at time intervals, the operation is continuous. Therefore, position measurement by GPS generally consumes a large amount of power.

  The location is important when an emergency is encountered, but it is sufficient if the location is known within some error. For example, it is not necessary to make multiple measurements to reduce the error to a few meters or less. If it is a sea or mountain, there may be an error of about 100 meters. In such a case, it is considered that the position measurement by GPS may be performed several times. If the number of times of measurement is about several times or less and only the emergency information is transmitted, continuous GPS measurement is not necessary, so that power consumption can be greatly reduced.

  As described above, if it is limited to the situation of emergency response, GPS position measurement and emergency communication can be performed with the minimum number of times and time, so power consumption is very low, even with portable devices such as watches, Reliable positioning and emergency information can be transmitted. In other words, it is possible to implement emergency information transmission without sacrificing the original functions of the wearable device (with very small restrictions on the original function) even for devices with large battery constraints such as wearable devices. It is.

  The present applicant proposes an electronic device or the like provided with power supply means for executing position measurement and emergency communication performed with a minimum number of times and time based on the above assumptions. Specifically, as illustrated in FIG. 1A, the electronic device 100 according to the present embodiment includes a position information acquisition unit 110 that acquires position information, and a transmission processing unit 120 that performs transmission processing of the acquired position information. And a battery 10 and a control unit that determines a normal state and an emergency state. When the battery 10 is determined to be in a normal state, power is not supplied to the position information acquisition unit 110 and the transmission processing unit 120. When the battery 10 is determined to be in an emergency state, the position information acquisition unit 110 and the transmission processing unit 120 are supplied with power. When the position information acquisition unit 110 determines that the state is an emergency state, the position information acquisition unit 110 acquires the position information in the emergency state based on the power supplied from the battery 10, and the transmission processing unit 120 Transmission processing of position information at is performed.

  Here, the emergency state is a state in which transmission of position information is necessary, and corresponds to a state in which an emergency such as a danger of life occurs for a user wearing the electronic device 100, for example. In addition, the normal state is a state where the necessity of transmitting position information is low, and specifically represents a state other than the emergency state. In FIG. 1A, the electronic device 100 includes a control unit 140 assuming FIG. 2A or FIG. 3A described later. However, the control unit here is not limited to the control unit 140 of FIG. 2A or 3A, and may correspond to the emergency control unit 170 of FIG.

  Here, the position information acquisition unit 110 includes, for example, a GPS antenna 111 that receives information from a satellite as shown in FIG. 2A, and a GPS reception unit that acquires position information based on information from the GPS antenna 111. 113 may be included. Hereinafter, the position information in this specification will be described as information acquired by GPS, but it is not hindered to use other position information. For example, the position information may be acquired using information from a base station of a mobile phone. However, in consideration of the fact that emergency information may be transmitted in the sea, mountains, etc., it is preferable to use positional information using information such as satellites like GPS.

  The battery 10 here represents a battery that supplies power to the position information acquisition unit 110 and the transmission processing unit 120 in an emergency state. Therefore, the example of FIG. 2A described later corresponds to the main battery 11, and the example of FIG. 3A and FIG. 5A described later corresponds to the dedicated battery 12.

  In this way, at least in the normal state, the battery 10 is not consumed for the operation of the position information acquisition unit 110 and the transmission processing unit 120. Therefore, it is possible to secure power for operation in an emergency state. It becomes possible.

  The above configuration is the case where the electronic apparatus according to the present embodiment includes the battery 10. That is, in FIG. 2 (A), FIG. 3 (A), FIG. 4 (A), and FIG. 5 (A), which will be described later, FIG. 2 (A) and FIG. 3 (A), which are wearable devices, or wearable devices. It is the structure corresponding to FIG. 5 (A) which is an attachment with which the battery 10 (dedicated battery-12) is built.

  However, the method of the present embodiment is not limited to this, and can be applied to an attachment using the external battery 10. Specifically, as illustrated in FIG. 1B, the electronic device 100 according to the present embodiment includes a position information acquisition unit 110 that acquires position information, and a transmission processing unit 120 that performs transmission processing of the acquired position information. And the terminal 130 for connection with an external device (the wearable device 200 shown in FIG. 4A in a narrow sense), and the position information acquisition unit 110 and the transmission processing unit 120 are determined to be in an emergency state, The operation is performed based on the electric power from the battery 10 included in the external device connected by the connection terminal 130, and the operation is not performed when it is determined that the normal state.

  The battery 10 in this case corresponds to the main battery 11 included in the wearable device 200 of FIG. Even in such a configuration, in the normal state, the main battery 11 is not consumed for the operation of the position information acquisition unit 110 and the transmission processing unit 120. Therefore, the position information acquisition unit 110 and the transmission processing unit 120 in the emergency state are not consumed. It is possible to increase the certainty of the operation.

  From another viewpoint, the method of the present embodiment is an emergency information transmission system incorporated in a wearable device, and is different from a battery (main body battery 11) included in the wearable device or the battery in an emergency state. Based on the power supplied from the dedicated battery 12, the location information acquisition unit 110 performs a process of acquiring the location information, and the transmission processing unit 120 performs a process of transmitting the acquired location information to the external device. Applicable to transmission system.

  The external device here does not indicate a wearable device (watch-type device) but represents a device that is a transmission destination of information. For example, when the transmission processing unit 120 transmits emergency information using wireless communication in a given frequency band, a wireless receiver that can receive radio waves in the frequency band is the external device.

  In this way, emergency information can be transmitted using wearable devices, so that a highly reliable system can be realized. At this time, the emergency information transmission system may be included in the wearable device itself as shown in FIG. 2 (A) or FIG. 3 (A). Or as shown to FIG. 4 (A) and FIG. 5 (A), you may be contained in the attachment apparatus attached to a wearable apparatus.

  In this specification, a block including the position information acquisition unit 110 and the transmission processing unit 120, that is, a block related to emergency information transmission is also referred to as an emergency information transmission system. That is, in the following, when the term “emergency information transmission system” is used, it refers to the position information acquisition unit 110, the transmission processing unit 120, etc., and is incorporated in a wearable device or an attachment. It depends on the situation.

  Hereinafter, a configuration example of the electronic device according to the present embodiment will be described in detail with reference to FIGS. 2 (A) to 5 (B). Thereafter, details of the control of the electronic device will be described separately for a case where the battery is shared and a case where the battery is provided.

2. System Configuration Example Next, an example of the system configuration and appearance of the electronic apparatus according to the present embodiment will be described. As described above, the electronic device according to the present embodiment may be a wearable device (watch-type device) or an attachment connected to the wearable device. The former is an example in which the wearable device and the emergency information transmission system are mounted as the same casing (the emergency information transmission system is included in the wearable device), and the latter is an example configured separately. Further, as described above, as the battery 10 for supplying power to the emergency information transmission system, a battery (main body battery 11) for operating the wearable device may be shared, or a dedicated battery 12 different from the main body battery 11 may be used. It may be provided.

  Therefore, in the following, four specific embodiments will be described with reference to the drawings from the two viewpoints of the same casing or separate bodies, a shared battery or a dedicated battery.

2.1 Same casing / shared battery First, an example of the same casing and a shared battery will be described with reference to FIGS. 2 (A) and 2 (B). An example of the system configuration of the electronic device in this case is FIG. 2A, and the electronic device 100 includes the above-described position information acquisition unit 110, transmission processing unit 120, and control unit 140. The position information acquisition unit 110 includes: For example, the GPS antenna 111 and the GPS receiving unit 113 may be included. Electronic device 100 also includes a transmission antenna 121 that transmits emergency information in accordance with the processing of transmission processing section 120.

  In addition to the above configuration, electronic device 100 further includes an internal circuit 150 that operates in a normal state. The control unit 140 controls the internal circuit 150 in a normal state and controls the position information acquisition unit 110 and the transmission processing unit 120 in an emergency state.

  Here, the internal circuit 150 is a circuit for realizing a function inherent to the wearable device (different from emergency information transmission). For example, as described later, if the wearable device is a biological information detection device, detection of biological information is performed. Do. Alternatively, when the wearable device has a general clock function, time information acquisition (for example, control of a timekeeping unit, etc.), display processing of the acquired time information, and the like may be performed.

  In this example, the battery 10 can supply power to the internal circuit 150, the position information acquisition unit 110, and the transmission processing unit 120. That is, the battery 10 here is the main battery 11 shared by the internal circuit 150 and the emergency information transmission system. When the main battery 11 is shared, if the power is excessively consumed by the operation of the internal circuit 150 in the normal state, the operation of the emergency information transmission system in the emergency state becomes impossible.

  That is, the control unit 140 of the electronic device 100 according to the embodiment shown in FIG. 2A needs to execute power supply control for suppressing such a situation. Specifically, even in the normal state, the power supply control of the battery 10 is performed so as to secure the battery capacity for operation of the position information acquisition unit 110 and the transmission processing unit 120 in the emergency state. A specific control example will be described later with reference to FIG.

  In addition, as illustrated in FIG. 2A, the electronic device 100 may further include an operation unit 160 that receives an operation by the user. The emergency information transmission system (position information acquisition unit 110 and transmission processing unit 120) operates based on the power from the battery when an operation on the operation unit 160 is detected.

  Here, the operation unit 160 is, for example, a button, but is not limited thereto, and various user interfaces can be used. For example, it may be a mechanical structure such as a dial instead of a button. Alternatively, if the electronic device 100 includes a touch panel or the like, the touch panel may be used as the operation unit 160. Alternatively, if the electronic device 100 has an acceleration sensor or the like, it is possible to detect the tap operation of the electronic device 100 by the user. That is, the operation unit 160 of this embodiment does not have a specific structure that is exposed to the outside of the device, but may be an interface realized by an acceleration sensor or the like.

  In any case, when a specific operation by the user is detected, it is sufficient to shift to an emergency state and transmit emergency information. In a narrow sense, the control unit 140 may acquire operation information from the operation unit 160 and determine whether or not there is an emergency state. In that case, the control unit 140 controls each unit of the electronic device 100 based on the determination result. Details of this point will be described later with reference to FIG.

  In addition, since it can transfer to an emergency state by a user's explicit operation by using the operation part 160, it can suppress changing to an emergency state accidentally, and can implement | achieve reliable control. However, it may be difficult for the user to perform an operation in an emergency, and there is a request for automatic emergency information transmission by the electronic device 100.

  Therefore, it may be determined whether or not there is an emergency state based on the information acquired by the internal circuit 150. For example, the internal circuit 150 is a biometric information acquisition circuit that acquires biometric information of the user, and the control unit 140 may determine whether or not an emergency state is present based on the biometric information.

  Various types of biological information can be considered here, and information representing the state of the user, such as heartbeat, pulse, blood pressure, electrocardiogram, and body temperature, can be widely used. Specifically, the internal circuit 150 may acquire information from a sensor unit 151 including a photoelectric sensor having a light emitting unit and a light receiving unit, and measure pulse wave information using the photoelectric sensor. In this case, the internal circuit 150 performs processing for obtaining information such as the pulse rate and the pulse wave RR interval based on sensor information from the photoelectric sensor. Note that measurement of pulse wave information using a photoelectric sensor is a well-known technique, and thus detailed description thereof is omitted.

  The biological information such as the pulse rate can define a numerical range (normal range) that a healthy user can take. The normal range has a large individual difference for each user, but if the information of the target user is continuously measured, the normal range can be set in consideration of the individual difference. Therefore, the normal range is stored in a storage unit (not illustrated) in FIG. 2A, and the control unit 140 is urgent when the acquired numerical value of the biological information of the user exceeds the normal range. You may determine with a state. Of course, the emergency state determination method based on the biological information is not limited to this, and various modifications can be made. For example, it is possible to perform a modification such as making a determination by combining a plurality of pieces of biological information, or changing the normal range or the biological information used in consideration of a user's disease or the like.

  In addition, it is important to transmit position information in an emergency state, but it is also useful to transmit information representing the state of the target user. For example, biometric information such as the pulse rate is very useful because it is information representing the health condition of the user. In the case of FIG. 2A, the biological information acquired by the internal circuit 150 of the electronic device 100 may be transmitted from the transmission processing unit 120.

  FIG. 2B illustrates an example of an external view of the electronic device 100 corresponding to FIG. FIG. 2B shows an example of a wristwatch-type wearable device, in which a main body portion 20 corresponding to a dial portion of a general timepiece and a part of a band portion 30 are described. In FIG. 2B, the position information acquisition unit 110 is arranged on one side of the band unit 30 with the main body unit 20 as a reference, and the transmission processing unit 120 is arranged on the other side. Further, an emergency button that is the operation unit 160 is disposed on the side surface of the main body unit 20, and the battery 10 (main body battery 11) is provided inside the main body unit 20. As described above, the electronic device 100 in FIG. 2B has the same housing as the emergency information transmission system, and the internal circuit 150 and the emergency information transmission system share a battery.

  Note that the structure of the electronic device 100 corresponding to FIG. 2A is not limited to FIG. For example, various modifications such as arranging both the position information acquisition unit 110 and the transmission processing unit 120 on one side of the band unit 30 with respect to the main body unit 20 are possible.

2.2 Same Case / Dedicated Battery Next, an example of the same case and a dedicated battery will be described with reference to FIGS. 3 (A) and 3 (B). As can be seen from FIG. 3A, except that the dedicated battery 12 is added and the operation unit 160 is mounted as a switch in a circuit for supplying power from the dedicated battery 12, FIG. Same as A).

  In the embodiment of FIG. 3A, the electronic device 100 includes a first battery (dedicated battery 12) that is the battery 10 and a second battery (main battery 11) that is different from the first battery. The second battery supplies power to the internal circuit 150 when determined to be in the normal state, and the first battery is not supplied with power when determined to be in the normal state.

  3A illustrates an example in which the operation unit 160 is used as a switch, and power is supplied from the first battery (dedicated battery 12) when the operation unit 160 is operated and the switch is turned on. However, it is not limited to this. For example, as in FIG. 2A, the control unit 140 may acquire operation information from the operation unit 160, and the control unit 140 may perform power control of the dedicated battery 12 based on the operation information. For example, a switch different from the operation unit 160 may be provided, and the second switch may be turned on / off based on the operation information.

  In this case, since the dedicated battery 12 does not consume power in the normal state, it is possible to suppress the possibility that the power is insufficient in an emergency state. That is, the battery 10, that is, the battery for the emergency information transmission system, here the first battery, which is the dedicated battery 12, and the battery for the internal circuit 150 (the main body battery 11, the second battery) are separated. Thus, the emergency information transmission system can be reliably operated in an emergency state.

  In addition, when operation with respect to the operation part 160 is detected, it is determined that it is an emergency state, the operation of the emergency information transmission system may be performed, and the biological information may be used for the determination of the emergency state, The point that the biological information acquired by the internal circuit 150 may be transmitted together with the position information is the same as in the case of FIG.

  FIG. 3B illustrates an example of an external view of the electronic device 100 corresponding to FIG. The basic configuration is the same as that in FIG. However, as described above, since the electronic device 100 in FIG. 3B has the same casing and a dedicated battery, the main body 20 of the electronic device 100 includes both the main battery 11 and the dedicated battery 12. Will be. Further, the point that various modifications can be made to the configuration of the electronic device 100 is the same as that in FIG.

2.3 Separate Attachment / Shared Battery Next, an example of a separate attachment / shared battery will be described with reference to FIGS. 4 (A) and 4 (B). An example of the system configuration of the electronic device 100 in this case is FIG. 4A, and the electronic device 100 includes the above-described position information acquisition unit 110, transmission processing unit 120, and connection terminal 130. The electronic device 100 may include a connector 131 used for physical connection with an external device, and the connector 131 may include the connection terminal 130. That is, here, the connector 131 is used for physical connection between devices, and the connection terminal 130 is used for electrical connection between devices. In addition, the position information acquisition unit 110 may include a GPS antenna 111 and a GPS reception unit 113, and the electronic device 100 may include a transmission antenna 121 that transmits emergency information according to the processing of the transmission processing unit 120. Is the same as FIG.

  In the case of FIG. 4A, the wearable device 200 and the electronic device 100 according to the present embodiment are separate. Therefore, the configuration corresponding to the control unit 140, the internal circuit 150, and the main battery 11 in FIG. 2A is not included in the electronic device 100, and the wearable device 200 (external device in a broad sense) has a corresponding configuration. Part 240, internal circuit 250, and main body battery 11. In the example of FIG. 4A, the main body battery 11 of the wearable device is the battery 10 that supplies power to the emergency information transmission system. The sensor unit 251 corresponds to the sensor unit 151 in FIG. 2A and includes a biological sensor such as a photoelectric sensor.

  In the example of FIG. 4A as well, the electronic device 100 may include the operation unit 160 in the same manner. As illustrated in FIG. 4A, the electronic device 100 includes an operation unit 160 that receives an operation by a user, and the position information acquisition unit 110 and the transmission processing unit 120 are configured to detect an operation on the operation unit 160. The operation is performed based on the electric power from the battery 10 (main battery 11).

  In this case, the operation information from the operation unit 160 is transmitted to the control unit 240 of the wearable device 200 via the connection terminal 130, and the control unit 240 determines that the state is an emergency state. Based on this control, the power from the main battery 11 is supplied to the position information acquisition unit 110 and the transmission processing unit 120 via the connection terminal 130.

  The operation unit 160 is not limited to that provided in the electronic device 100 (attachment), and may be provided in the wearable device 200. In this case, the control flow does not change, but the control unit 240 of the wearable device 200 acquires operation information from an operation unit (not shown in FIG. 4A) inside the wearable device 200.

  Note that the attachment, which is the electronic device 100 according to the present embodiment, is desirably in a state of being attached to the wearable device 200, assuming the possibility of an emergency state. However, it is not hindered to remove the attachment and use the wearable device 200 as a single unit. In this case, if an operation unit is provided in the wearable device 200, the operation unit may become a useless configuration that is not used in a normal state. That is, from the viewpoint of efficiently mounting the hardware configuration, it is desirable to provide the operation unit 160 on the electronic device 100, that is, the attachment side in the case of FIG.

  However, the case where the operation unit is also used for other operations of the wearable device 200, or there is no need to newly add a hardware configuration for the operation unit as in the case of performing tap detection with an acceleration sensor or the like. Therefore, it is not hindered to provide the operation unit on the wearable device 200 side.

  Note that biometric information may be used to determine whether or not an emergency state is the same as in the example of FIGS. 2 (A) to 3 (B). The control unit 240 of the wearable device 200 may acquire biological information from the internal circuit 250 (biological information acquisition circuit), and may determine whether or not the emergency state is based on the acquired biological information. And when it determines with an emergency state, what is necessary is just to supply electric power to the positional information acquisition part 110 and the transmission process part 120 from the battery 10 via the terminal 130 for a connection. Further, the biometric information acquired by the internal circuit 250 may be transmitted together with the position information as in the case of FIG.

  However, in the case of FIG. 4A, biometric information or the like cannot be acquired inside the electronic device 100 (attachment), and thus it is necessary to acquire information from an external device such as the wearable device 200. Specifically, the transmission processing unit 120 may perform processing of acquiring information from an external device (in a narrow sense, the wearable device 200) via the connection terminal 130 and transmitting the information. Specifically, the external device (wearable device 200) is a biological information detection device that detects biological information, and the transmission processing unit 120 acquires the biological information as the information via the connection terminal 130, You may perform the process which transmits biometric information.

  If it does in this way, it will become not limited to position information, but it will become possible to transmit information useful in emergency response. At this time, as described above, it is useful to transmit information from an external device such as biological information together with the position information (in association with the position information). However, in view of the fact that biometric information or the like is useful information that represents the state of the user even if it is a single unit, it is not necessarily associated with the position information. Processing such as transmission may be performed. Alternatively, in the electronic device 100, the position information and the biological information or the like may be transmitted independently without being associated with each other, and the information receiving side may perform a process of associating the information received independently. . Note that it is not necessary to associate the biological information and the like with the position information in the electronic device 100 in the case of FIG. 2 (A) to FIG. 3 (B) described above or FIG. 5 (A) and FIG. The same applies to the case of 5 (B).

  In the above description, the method of the present embodiment is applied to the electronic device 100, that is, the example of FIG. 4A has been described as being applied to an attachment, but is not limited thereto. The technique of this embodiment can be applied to an information processing system including the electronic device 100 (attachment) and an external device (wearable device 200). The electronic device 100 and the wearable device 200 need to be connected via the connection terminal 130, but the connection terminal 130 may be a dedicated terminal. In this case, the electronic device 100 and the wearable device 200 are mounted on the assumption that they are exclusively used for the information processing system according to the present embodiment.

  Of course, the connection terminal 130 is not limited to this, and a standardized terminal such as USB (Universal Serial Bus) or microUSB can also be used.

  FIG. 4B shows an example of an external view of the electronic device 100 corresponding to FIG. 4A and an external device (wearable device 200) to which the electronic device 100 is connected. In FIG. 4B, the electronic device 100 has a bent plate shape so as to be supported along the band portion 30 of the wearable device 200 that is a watch-type device. As an example, as shown in FIG. 4B, a rectangular plate is bent, and the long side direction is the direction along the band part 30 of the wearable device 200, and the connection is made along the short side direction. A terminal 130 is provided. In the electronic device 100, the position information acquisition unit 110 is arranged on the surface (upper surface) opposite to the surface (bottom surface) on the side facing the band unit 30. The transmission processing unit 120 is disposed on one of the surfaces, and the operation unit 160 is disposed on the other side. Further, the battery 10 (main body battery 11) is provided inside the main body 30.

  Naturally, the configuration of the electronic device 100 corresponding to FIG. 4A is not limited to that in FIG. 4B, and the shape of the electronic device 100, the arrangement of the position information acquisition unit 110 and the transmission processing unit 120, and the like are various. Can be implemented.

2.4 Separate Attachment / Dedicated Battery Next, an example of a separate attachment and dedicated battery will be described with reference to FIGS. 5 (A) and 5 (B). As can be seen from FIG. 5A, the dedicated battery 12 is added to the electronic device 100 (attachment), and the operation unit 160 is implemented as a switch in a circuit that supplies power from the dedicated battery 12. 4 and FIG. 4A except that the emergency control unit 170 is included.

  As described above, the electronic device 100 according to FIG. 5A includes the position information acquisition unit 110, the transmission processing unit 120, and the battery 10 (dedicated battery 12).

  Furthermore, as shown in FIG. 5A, the electronic device 100 may include a connector 131 for attaching (connecting) the electronic device 100 to an external device. By having the connector 131, the electronic device 100 (attachment) according to FIG. 5A is physically connected (fixed) to an external device such as the wearable device 200. As a result, loss of the electronic device 100 or operation by a third party can be suppressed. The connector 131 includes a connection terminal 130 used for electrical connection between the electronic device 100 and an external device, and the position information acquisition unit 110 and the transmission processing unit 120 are connected to the external device via the connection terminal 130. It may be electrically connected. This is the same as FIG. 4 (A).

  The difference from FIG. 4A is that the battery 10 here is a battery for the position information acquisition unit 110 and the transmission processing unit 120, that is, a dedicated battery 12. Therefore, the battery 10 (dedicated battery 12) does not supply power to the external device in both the normal state and the emergency state. As a result, the dedicated battery 12 does not consume power in the operation of the external device, for example, the operation of the internal circuit 250 of the wearable device 200, and can reliably supply power in an emergency state.

  In addition, as illustrated in FIG. 5A, the electronic device 100 further includes an operation unit 160 that receives an operation by a user, and the position information acquisition unit 110 and the transmission processing unit 120 are based on an operation on the operation unit 160. When it is determined that the state is an emergency state, the operation is performed based on the electric power from the battery 10. The operation unit 160 may be provided in the same manner as in FIG. 4A. At this time, operation information from the operation unit 160 is received via the connection terminal 130 as in the example described above. The control unit 240 may determine that the control unit 240 is in an emergency state. The difference in this case is whether the battery 10 is the main battery 11 (FIG. 4A) or the dedicated battery 12 (FIG. 5A).

  However, since the attachment, which is the electronic device 100 according to FIG. 5, includes all of the dedicated battery 12, the position information acquisition unit 110, and the transmission processing unit 120, the electronic device 100 alone is not necessary in cooperation with the wearable device 200. It is also possible to work with. That is, the configuration including the connection terminal 130 so as to be attachable to the wearable device 200 from the viewpoint of avoiding the risk of loss or the like described above is shown, but the operation itself in an emergency state depends on the wearable device 200. Never do. That is, when the operation unit 160 is operated, the control unit 240 of the wearable device 200 may be configured to operate without determining whether or not an emergency state exists.

  The emergency control unit 170 shown in FIG. 5A mainly performs control related to determination of an emergency state and operation control in an emergency state, and determines an emergency state based on operation information from the operation unit 160. When the emergency state is determined, control is performed to supply power from the battery 10 to the position information acquisition unit 110 and the transmission processing unit 120.

  Moreover, the point which may use biometric information for determination of whether it is an emergency state is the same as that of FIG. 4 (A). Specifically, the biological information may be acquired from the internal circuit 250 (biological information acquisition circuit), and it may be determined whether or not the emergency state is based on the acquired biological information. In this case, since cooperation with the wearable device 200 is assumed, the main body that performs the determination may be the control unit 240 of the wearable device 200 or the emergency control unit 170 of the electronic device 100.

  In addition, the transmission processing unit 120 may acquire information from an external device (wearable device 200 in a narrow sense) via the connection terminal 130 and perform processing for transmitting the information together with the position information. The method of the embodiment can be applied to an information processing system including the electronic device 100 (attachment) and the external device (wearable device 200), as in FIG.

  FIG. 5B shows an example of an external view of the electronic device 100 corresponding to FIG. The basic configuration is the same as that in FIG. However, as described above, since the electronic device 100 in FIG. 5B is a separate attachment and a dedicated battery, the dedicated battery 12 is built in the electronic device 100 (attachment). Further, the point that various modifications can be made to the shape and the like of the electronic device 100 is the same as in FIG.

3. Details of Control Next, details of control of the electronic device 100 according to the present embodiment will be described. Specifically, when the main battery 11 is shared as the battery 10 (corresponding to FIG. 2A and FIG. 4A), and when the dedicated battery 12 is provided (FIG. 3A and FIG. 5A). This will be explained separately. In the following, in order to simplify the description, it is assumed that control is performed by the example corresponding to FIGS. 2A and 3A, that is, the control unit 140 of the electronic device 100. It may be performed by the control unit 240 of the wearable device 200 of FIG. 4 (A) or FIG. 5 (A) or the emergency control unit 170 of FIG. 5 (A).

3.1 Shared battery First, an example of a shared battery will be described. As described above, the battery in this case is one of the main body batteries 11, and the operation of the internal circuit 150 and the like (hereinafter referred to as main body operation) is performed in a normal state. Therefore, in order to perform position measurement and emergency information transmission in an emergency state, it is necessary to secure a minimum power.

  FIG. 6 shows a specific example of power control in this case. The horizontal axis of FIG. 6 represents time, and the rectangle shown in the lower part of FIG. 6 is a graph of the remaining battery level at the corresponding timing. The state at the timing t1 represents a state where the battery remains A1 (%). In addition, the remaining battery level corresponding to the hatched area in FIG. 6, that is, the remaining battery level corresponding to the whole A0 (%), indicates that the remaining battery level required for performing position measurement and emergency information transmission in an emergency state. Represents quantity. Here, for the sake of easy understanding, the remaining amount of the battery is expressed as a percentage. However, in practice, an embodiment in which the voltage value of the battery is monitored can be considered.

  If the remaining battery level falls below A0 (%), the execution of emergency information transmission cannot be guaranteed even if the state shifts to an emergency state. Therefore, the control unit 140 performs control to monitor the remaining battery level so that it does not fall below A0 when performing the main body operation in the normal state. Specifically, a threshold value (charging level) Th that satisfies Th> A0 is provided with a certain margin, and it is only necessary to monitor whether the remaining battery level is below Th. At timing t1, since A1> Th, it can be said that the remaining battery level is sufficient.

  In the present embodiment, emergency information transmission is assumed as described above. Therefore, the accuracy of position detection is not so necessary, and the need for continuous position measurement is low. For example, an error in the order of 100 m is not a big problem, so it is often sufficient to obtain a single position measurement result. Actually, there is a possibility that the position measurement (information reception from the satellite) may fail. Therefore, it is preferable to perform the position measurement operation a plurality of times. The remaining amount is small. That is, in FIG. 6, A0 and Th are drawn so as to have a certain remaining amount for convenience of illustration, but in this embodiment, A0 and Th are sufficiently small values, and at least a remaining amount of A0 or more is secured. Even if it does, the restriction | limiting with respect to a main body operation | movement (point that the battery amount which can be used for a main body operation | movement will decrease) will not become a big problem.

  While the main unit is operating, the remaining battery level gradually decreases. For example, in the battery remaining amount determination at the timing t2, the remaining battery amount is reduced to A2 (%), and A2 <Th. Therefore, if the main body operation is continued as it is, there is a risk that the remaining battery level will be lower than A0. Therefore, as shown in FIG. 6, based on the determination at the timing t2, the main body operation is temporarily stopped to perform charging. In this case, a notification that prompts the user to charge may be performed, and the notification can take various methods such as screen display, vibration, generation of sound and light, and the like. Note that the notification may be performed only for a certain period of time because power consumption is also consumed by continuing the notification for prompting charging.

  When the user performs charging and the remaining battery level reaches a sufficient level as at timing t3, the main body operation is resumed. In this case, the internal circuit 150 or the like is stopped during the charging operation, and the operation of the internal circuit 150 or the like is resumed after the charging operation is completed and when the remaining battery charge is equal to or more than Th. Good. Alternatively, the remaining battery level is monitored during charging, and when the remaining battery level is equal to or greater than Th, the operation of the main body may be resumed even during charging, and various modifications can be made. In this way, power can be secured so as not to fall below the minimum emergency transmission amount (A0), and emergency information transmission with high certainty can be performed.

  Next, a control example of the main body operation and the emergency information transmission operation when it is determined to be in an emergency state will be described with reference to FIG. As described above, in this embodiment, when the operation unit 160 is operated, or when an abnormality is detected based on biological information (such as a weak heartbeat, a decrease in blood pressure, an increase in body temperature), the state shifts to an emergency state. At this time, since the power supply control described above with reference to FIG. 6 is performed, it can be considered that the remaining battery level is at least A0 or more at the time of transition to the emergency state.

  Here, A0 is the remaining battery capacity required for the emergency information transmission operation. If the remaining battery level at the time of transition to the emergency state is A0, if a part of the remaining battery level is used for an operation other than the emergency information transmission operation, for example, the main body operation, power will be consumed until the transmission of the emergency information is completed. There may be a shortage.

  As described above, the charging level Th has a margin with respect to A0. For example, when the margin is M, Th = A0 + M. However, the power that can be used for emergency information transmission when the main body operation is continued even in an emergency state and the power of M or more is consumed for the main body operation in the emergency state (until the completion of the emergency information transmission operation in a narrow sense). Will fall below A0, and there is a possibility that emergency information cannot be transmitted.

  Therefore, when the main battery 11 is shared, it is preferable to suppress the supply of power from the main battery 11 to other than the emergency information transmission system in an emergency state. Specifically, the internal circuit 150 stops operating when it is determined as an emergency state. This can be realized by the control unit 140 performing control to stop the supply of power from the battery 10 to the internal circuit 150 when it is determined to be an emergency state. In an emergency state, the main body operation may be stopped (sleep). This is illustrated in FIG. Note that the stop of the operation here is not limited to the case of completely stopping the operation, and may be a transition to the power saving mode. For example, even in a situation where the main body operation is stopped, an embodiment in which some circuits are operated in order to return at high speed (the main body is set to sleep) is also used to stop the main body operation here. included.

  The horizontal axis in FIG. 7 represents time, and it is assumed that an operation of the operation unit 160 or an abnormality in biological information is detected at the timing t4 in FIG. In this case, the operation is performed in the normal state before t4, and the state is shifted to the emergency state at t4. In the case of a shared battery, as shown in FIG. 7, the GPS transmission operation (emergency information transmission operation) is started and the main body operation is stopped at the timing of transition to the emergency state. In this case, since the internal circuit 150 and the like do not operate, biometric information is not acquired. Therefore, when realizing the above modification in which the positional information and the biological information are transmitted together, the biological information is not the information at the time of acquiring the positional information but the information acquired before that (for example, at the time of detecting the abnormality). become.

  When the series of emergency operations is completed, the operation of the main body is resumed. In an emergency operation, as described above, GPS measurement may be performed several times without being received well, and the required time may change. Therefore, when the position information is appropriately acquired, the emergency state is terminated, the emergency information transmission operation is stopped, and the main body operation is restarted. Alternatively, the transition to the normal state and the restart of the main body operation may be performed on the condition that a predetermined time (for example, about 10 minutes) has elapsed. In this way, by stopping the main body operation in an emergency state, it is possible to suppress battery consumption and to improve the certainty of the emergency information transmission operation.

  4A, the information processing system includes an electronic device 100 (attachment) and an external device (wearable device 200), and the external device includes an internal circuit 250 that operates in a normal state, The control unit 240 controls the internal circuit 250 in a normal state and controls the position information acquisition unit 110 and the transmission processing unit 120 in an emergency state. Then, the control unit 240 stops supplying power from the battery 10 to the internal circuit 250 when it is determined to be in an emergency state, and the internal circuit 250 stops operation when it is determined to be in an emergency state. Will do.

3.2 Dedicated Battery In the example having the dedicated battery 12 in contrast to the above-described example of the shared battery, it is not assumed that the dedicated battery 12 is used for anything other than the emergency information transmission operation. Therefore, it is not necessary to monitor the remaining amount of the dedicated battery 12, and it is not necessary to reserve a part of the power of the main battery 11 for emergency use. Therefore, it is not necessary to perform the monitoring control of the remaining battery level as shown in FIG.

  Even in an emergency state, the main body operation is performed by consuming the main body battery 11. That is, even if the main body operation is executed in an emergency state, the certainty of the emergency information transmission operation is not affected. Therefore, in the embodiment having the dedicated battery 12, as shown in FIG. 8, the main body operation may be continued even after the transition from the normal state to the emergency state (t6). Of course, the main body operation is continued even after the emergency information transmission operation is completed and the normal state is restored (t7).

  Further, the emergency information transmission operation is the same as that in FIG. 7, and the operation is started at the transition timing t6 to the emergency state, and when the operation is completed, the operation shifts to the normal state (t7). At this time, in FIG. 7 described above, the completion of the emergency information transmission operation was a trigger for restarting the main body operation along with the return to the normal state. However, in the embodiment having the dedicated battery 12, the main body operation is continued. , No restart trigger is required. However, a notification that the emergency information transmission operation has been completed may be sent to the main body side (for example, to the control unit 240 of the wearable device 200), and some processing based on the notification is further performed on the main body side. May be. As an example, the user may be notified that the emergency information transmission operation has been completed.

  The dedicated battery 12 here may be a commercially available thin button battery. The button battery is easily available and is rarely used in the present embodiment, so that the battery can be held well and the possibility of battery shortage in an emergency can be reduced.

  Although the present embodiment has been described in detail as described above, it will be easily understood by those skilled in the art that many modifications can be made without departing from the novel matters and effects of the present invention. Accordingly, all such modifications are intended to be included in the scope of the present invention. For example, a term described at least once together with a different term having a broader meaning or the same meaning in the specification or the drawings can be replaced with the different term in any part of the specification or the drawings. Further, the configuration and operation of the electronic device and the like are not limited to those described in this embodiment, and various modifications can be made.
