[0020] In the present invention, the term "disaster" means to have suffered a disaster. The disaster is not particularly limited, and examples thereof include natural disasters such as earthquakes, typhoons, heavy rains, cold waves, avalanches, volcanic eruptions, and extreme heat, and man-made disasters such as major fires, major explosions, terrorism, strikes, wars, and riots.

[0021] The embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments. In each of the drawings, the same parts are given the same reference numerals. In addition, the explanations of each embodiment can be mutually incorporated unless otherwise specified, and the configurations of each embodiment can be combined unless otherwise specified.

[0022] [Embodiment 1] FIG. 1 is a block diagram showing an example of a configuration of a data acquisition device 10 according to the present embodiment. As shown in FIG. 1, the device 10 includes a location information acquisition unit 11, a driving control unit 12, a moving unit 13, a wireless power supply unit 14, a battery unit 15, a data acquisition unit 16, a storage unit 17, and a data transmission unit 18. The device 10 is preferably an unmanned device capable of automatic driving, and may be a device that travels on the ground, may be a device that navigates on water, or may fly in the air. The device 10 is preferably a drone, and is preferably a flying drone that flies in the air. The automatic driving method for the automatic driving of the device 10 is not particularly limited, and may be, for example, a GPS method. The GPS method is, for example, a method of measuring the current coordinates of the device 10 and the coordinates of a destination (for example, a location indicated by location information indicating the location of a target device, which will be described later) and setting a movement (flight) route. The device 10 may be, for example, a drone in which the program of the present invention is installed.

[0023] The device 10 may be, for example, a single device including each of the above-mentioned units, or a device to which each of the above-mentioned units can be connected via a communication network. The device 10 may also be connected to an external device, which will be described later, via the communication network. The communication network is not particularly limited, and any known network may be used, for example, wired or wireless. Examples of the communication network include the Internet line, WWW (World Wide Web), telephone line, LAN (Local Area Network), SAN (Storage Area Network), and DTN (Delay Tolerant Networking). Examples of wireless communication include WiFi (Wireless Fidelity) and Bluetooth (registered trademark). The wireless communication may be either a form in which each device directly communicates with each other (Ad Hoc communication) or an indirect communication via an access point.

[0024] 2 illustrates a block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage unit 17, an input device 104, a display device 105, a communication device 106, a moving unit 13, and a battery unit 15. The various units in the hardware configuration of the device 10 are connected to each other via the bus 103 and their respective interfaces (I / F).

[0025] The central processing unit (Central Processing Unit) 101 is responsible for the overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program of the present invention and other programs, and also reads and writes various information. Specifically, the central processing unit 101 functions as, for example, a position information acquisition unit 11, a steering control unit 12, a wireless power supply unit 14, a data acquisition unit 16, and a data transmission unit 18.

[0026] The bus 103 can also be connected to, for example, an external device. Examples of the external device include an external database, a printer, the target device (for example, a storage device of the present invention described later), and a base station of the present invention described later. The present device 10 can be connected to the communication line network by, for example, a communication device 106 connected to the bus 103, and can also be connected to an external device via the communication line network. In addition, for example, when a data recovery system device of the present invention described later includes a plurality of data acquisition devices 10, the present device 10 may be capable of communicating with the other data acquisition devices 10 by, for example, the communication device 106.

[0027] An example of the memory 102 is a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operation programs, such as the program of the present invention, stored in the storage unit 17 described below, and the central processing unit 101 receives data from the memory 102 and executes the programs. The main memory is, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0028] The storage unit 17 is also called an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage unit 17 stores an operation program including the program of the present invention. The storage unit 17 may be, for example, a combination of a recording medium and a drive that reads and writes from the recording medium. The recording medium is not particularly limited, and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage unit 17 may be, for example, a hard disk drive (HDD) in which the recording medium and the drive are integrated, or a solid state drive (SSD).

[0029] In the present device 10, the memory 102 and the storage unit 17 can also store access information and log information from an administrator, as well as information acquired from an external database (not shown).

[0030] The device 10 further includes, for example, an input device 104, a display device 105, a moving unit 13, and a battery unit 15. The input device 104 is, for example, a touch panel, a keyboard, a mouse, etc. The display device 105 is, for example, an LED display, a liquid crystal display, etc. The moving unit 13 is, for example, a wheel, a caterpillar, a water jet propulsion machine, a propeller, a motor, a flight controller, etc., but is not particularly limited as long as it can move the device 10. When the device 10 is a flying drone, the moving unit 13 is preferably, for example, a propeller, a motor, a flight controller, etc. The battery unit 15 is a device that stores power and supplies power to each part of the device 10 that requires power.

[0031] The device 10 includes a wireless power supply unit 14. The wireless power supply unit 14 is a device that supplies power stored in a battery unit 15 of the device 10 to the target device by a non-contact power transmission method. The non-contact power transmission method is also called wireless power transfer (WPT), and examples of the method include an electromagnetic induction method, a magnetic resonance method, a magnetic coupling method, and a microwave transmission method, and any method may be used. A specific example of the non-contact power transmission method using the electromagnetic induction method is the international standard Qi.

[0032] The target device to which the wireless power supply unit 14 supplies power may be, for example, a device capable of acquiring power from the outside by a non-contact power transmission method, and examples of such devices include a storage device, a smartphone, a wearable device, a notebook computer, and the like, that has a function of acquiring power by a non-contact power transmission method. The storage device is not particularly limited, and is, for example, a storage device including a disaster-resistant housing and a battery, and is preferably the storage device of the present invention described below. The storage device is, for example, a storage device at a main site.

[0033] Next, an example of the data acquisition method of the present invention will be described based on the flowchart of Fig. 3. The acquisition method of this embodiment is implemented as follows, for example, using the data acquisition device 10 of Figs. 1 and 2. Note that the acquisition method of this embodiment is not limited to the use of the data acquisition device 10 of Figs. 1 and 2. In the following description, an example will be described in which the data acquisition device 10 is a flying drone, the pre-specified location is a communication base station (base station), and the target device is a storage device that has been affected by a disaster (disaster-affected storage device), but the present invention is not limited thereto.

[0034] First, the location information acquisition unit 11 acquires location information indicating the location of the affected storage device (target device) (S11, location information acquisition step). The location information is not particularly limited, and may be, for example, coordinate information of a global positioning system (GPS). The location information may be acquired directly from the affected storage device by the device 10 receiving location information transmitted by the affected storage device, or may be acquired indirectly by receiving location information transmitted by the affected storage device to a base station (for example, a base station of the present invention described later) from the base station. The location information is acquired, for example, via the wireless communication. In addition, when the affected storage device is a storage device included in a data recovery system device of the third embodiment described later, for example, a transmission signal transmitted by the storage device may be received, and the coordinate information of the storage device included in the transmission signal may be acquired as the location information. In this case, it is preferable because the location of the storage device can be identified even if the storage device is in a situation where it cannot perform GPS communication due to the influence of a disaster or the like.

[0035] Next, the operation control unit 12 controls the moving unit 13 of the device 10 to move the device 10 to the position indicated by the position information (S12, first operation control step). After the device 10 moves to the position, the operation control unit 12 may control the moving unit 13 to stop the device 10 at the position. If the device 10 is a flying drone, the stop may be, for example, a hovering state, and the device 10 may be, for example, in a hovering state during a wireless power supplying step and a data acquisition step described later. The "position indicated by the position information" is, for example, a location specified from the coordinate information of the affected storage device included in the received position information, and is not particularly limited as long as it is a position where power can be supplied from the device 10 to the target device by a non-contact power transmission method in a wireless power supplying step described later, and data can be acquired from the target device by wireless communication in a data acquisition step described later. The control by the steering control unit 12 may, for example, set a movement route calculated by the device 10 based on the position information of the target device and the position information of the device 10, and control the device 10 to move along the movement route, or may obtain movement instruction information including a movement route from a management device (e.g., the communication base station) outside the device 10, and control the device 10 to move according to the movement instruction information. Note that the waiting location of the device 10 before moving is not particularly limited as long as it is a location where the position information can be obtained, and may be any location, for example, a location where the communication base station is located.

[0036] Next, the wireless power supply unit 14 supplies the power stored in the battery unit 15 to the affected storage device by a non-contact power transmission method (S13, wireless power supply step). Specific examples of the non-contact power transmission method are as described above, and can be set appropriately depending on the method by which the target device (storage device) can obtain power. Note that the amount of power supplied to the storage device in the wireless power supply step may be a preset amount of power, or may be an amount of power set based on the amount of power stored in the battery unit 15, the operating time of the device 10, the amount of power required for traveling from the standby location to the location of the storage device, the amount of power required for data acquisition processing, etc.

[0037] Next, the data acquisition unit 16 acquires data in the memory unit of the affected storage device using wireless communication (S14, data acquisition step). Then, the acquired data is stored by the memory unit 17 (S15, storage step). The wireless communication is, for example, as described above. For example, if the affected storage device is a main site, the acquired data may be data that has not been transferred to a remote site, or may be all data in the affected storage device.

[0038] Prior to S14, the data acquisition unit 16 may, for example, acquire instruction information from the base station and acquire the data according to the instruction information. The instruction information is information related to the acquisition of the data, and includes, for example, information instructing the identification information and address (data storage area) of the disk from which the data is acquired in the storage unit of the target device. In this case, the data acquisition unit 16 and the storage unit 17 may, for example, further acquire and store storage information (target device information) in the acquisition process and the storage process. The storage information (target device information) may include, for example, information including the identification information of the affected storage device (target device), disk information in the storage unit of the affected storage device (target device), and the like. The disk information may, for example, include information including the identification information of the disk on which the acquired data was stored, the address of the disk, the size of the acquired data, and the size of all data stored on the disk.

[0039] In FIG. 3, the wireless power supply step (S13), the data acquisition step (S14), and the storage step (S15) are performed in this order, but the data acquisition method of the present invention is not limited to this order, and the wireless power supply step (S13), the data acquisition step (S14), and the storage step (S15) may be performed in parallel.

[0040] Next, the steering control unit 12 controls the steering of the moving unit 13 to move the device 10 to a pre-specified location (S16, second steering control step). The pre-specified location is not particularly limited as long as it is a location where the data of the storage device acquired and stored in the data acquisition step and the storage step can be transmitted to the communication base station, and a specific example is the location of the base station, as described above.

[0041] Then, the data transmission unit 18 transmits the data to the base station (S17, data transmission step), and the process ends (END). The transmission of data to the base station is not particularly limited, and may be, for example, wired communication or wireless communication.

[0042] Note that the device 10 may end the process (END) when, for example, in the wireless power supply step, it is determined that power cannot be supplied to the target device by the wireless power supply unit 14. In this case, for example, the steering control unit 12 moves the device 10 to the pre-specified location (for example, a base station). Then, it is preferable that the data transmission unit 18 transmits to the base station the location information of the target device acquired by the location information acquisition unit 11 and information that power could not be supplied to the target device.

[0043] Furthermore, steps S12 to S17 (the first steering control step, the wireless power supply step, the data acquisition step, the storage step, the second steering control step, and the data transmission step) may be executed repeatedly, for example.

[0044] In this case, it is preferable that, prior to S14, the data acquisition unit 16 acquires, for example, instruction information from the base station and acquires the data in accordance with the instruction information. The instruction information is, for example, as described above.

[0045] Next, in S15, the storage unit 17 stores, for example, the data and disk information on the disk in which the acquired data was stored. The disk information includes, for example, identification information of the disk and information specifying an address (data storage area).

[0046] Next, in S16, the device 10 is moved to a pre-specified location. At this time, it is preferable to charge the power of the battery unit 15 of the device 10, for example.

[0047] Next, in S17, the data transmission unit 18 transmits, for example, the data and the disk information to the base station.

[0048] Then, after the amount of power stored in the battery unit 15 becomes sufficient to execute S12 to S17, S12 to S17 are executed again.

[0049] There is a limit to the amount of power that can be stored in the battery unit 15 of the data acquisition device 10 and the amount of data that can be stored in the memory unit 17. Therefore, in the data acquisition method of this embodiment, by repeatedly performing steps S12 to S17 in this manner, it is possible to acquire more data in the memory unit of the target device.

[0050] In the above description, an embodiment using only one data acquisition device 10 has been described as an example, but the data acquisition method of the present invention is not limited to this, and multiple data acquisition devices 10 may be used. In this case, in the data acquisition step, it is preferable that the data acquisition unit 16 of each data acquisition device 10 acquires instruction information from the base station, for example, and acquires data according to the instruction information. In this case, the instruction information includes, for example, information instructing each data acquisition device 10 to acquire data stored in different areas of the storage unit of the target device. This makes it possible to suppress the acquisition of duplicate data between multiple data acquisition devices 10, and to acquire data in the target device more efficiently.

[0051] According to the data acquisition device 10 of the present embodiment, power is supplied to the target device by a non-contact power transmission method, and data in the memory unit of the target device can be acquired by wireless communication. Therefore, even if the power supply to the target device is cut off due to a disaster or the like, information in the target device can be easily acquired. In disaster areas, for example, infrastructure facilities such as transportation means and communication means are often damaged, or it is often impossible to approach the location of the disaster-affected target device. Even in such cases, the device 10 can easily go to the disaster area and acquire data. Furthermore, since there is no need for workers to go to the disaster area, the safety of the workers is ensured. Therefore, according to the data acquisition device 10 of the present embodiment, for example, data in the disaster-affected target device can be easily restored.

[0052] In this embodiment, the target device is the storage device of the present invention that has been affected by a disaster, and data is acquired (also referred to as rescue) from the storage device. However, the present invention is not limited to this. In the data acquisition method of this embodiment, the target device may be a smartphone or the like owned by a disaster victim (lost or missing person), and the data acquisition device of the present invention may supply power to the smartphone owned by the disaster victim (lost or missing person) and acquire data in a storage unit of the smartphone. In this case, the data may be, for example, location information of the smartphone, "approximate time of disaster (lost or missing person)", "hungry", "whether injured, where injured", "surrounding situation" and other information input by the disaster victim after the disaster. In this case, the data acquisition device of the present invention can obtain information such as the location and current situation of the disaster victim (lost or missing person), so the data acquisition device of the present invention can be effectively used for rescuing the disaster victim (lost or missing person).

[0053] [Embodiment 2] The data acquisition device of this embodiment is similar to that of embodiment 1, except that it further includes an operation time determination unit that determines the operation time of the data acquisition device based on a parameter related to the amount of power stored in a battery unit of the data acquisition device.

[0054] Fig. 4 is a block diagram showing an example of the configuration of the data acquisition device 10A of this embodiment. As shown in Fig. 4, the data acquisition device 10A further includes an operating time determination unit 19 in addition to the data acquisition device 10 of the embodiment. The hardware configuration of the data acquisition device 10A is similar to that of the data acquisition device 10 of Fig. 2, except that the central processing unit 101 further functions as the operating time determination unit 19 in addition to the configuration of the data acquisition device 10 of Fig. 2.

[0055] Next, the data acquisition method of the second embodiment will be described with reference to the flowchart of Fig. 5. The data acquisition method of the second embodiment can be implemented, for example, by using the data acquisition device 10A of the second embodiment shown in Fig. 4. Note that the data acquisition method of the second embodiment is not limited to the use of the data acquisition device 10A.

[0056] First, S11 is carried out in the same manner as S11 in the data acquisition method of the first embodiment.

[0057] Next, the operating time determination unit 19 determines the operating time of the data acquisition device 10A based on parameters related to the amount of power stored in the battery unit 15 of the data acquisition device 10A (S111, operating time determination step). The operating time is, for example, the time during which the data acquisition device 10A performs the wireless power supply step, the data acquisition step, and the data storage step (steps S13, S14, S15) after moving to the position indicated by the position information of the target device. The parameters include, for example, at least one of the following (1) to (3). (1) The amount of power consumed in moving to the location indicated by the location information and moving from the location indicated by the location information to the pre-specified location (2) Amount of power consumed during the data acquisition process by the data acquisition unit. (3) Amount of power consumed by the wireless power supply unit to supply power to the target device.

[0058] The operation time determination unit 19 can determine the operation time, for example, as follows. The operation time determination unit 19 calculates, for example, the parameters (1) to (3). Then, the operation time determination unit 19 determines the operation time, that is, the time to perform the wireless power supply process, the data acquisition process, and the data storage process (S13, S14, S15 processes), so that the total power consumption indicated by each parameter does not exceed the amount of power stored in the battery unit 15. Specifically, for example, the operation time determination unit 19 subtracts the amount of power (1) from the amount of power stored in the battery unit 15, and determines the operation time from the remaining amount of power based on the amounts of power (2) and (3). According to such a process, for example, it is possible to prevent the data acquisition device 10A from running out of battery before returning to the pre-specified location.

[0059] The operation time determination unit 19 may allocate, as the amount of power (1), for example, an arbitrary ratio of the total amount of power stored in the battery unit 15, or may allocate a value calculated as the amount of power consumed in traveling back and forth from the standby location of the data acquisition device 10A to the location of the target device. In the former case, the operation time determination unit 19 may set, as the amount of power (1), for example, 20%, with the total amount of power in the battery unit 15 being 100%. In the latter case, the operation time determination unit 19 may calculate, as the amount of power (1), the amount of power consumption, based on, for example, the distance from the standby location to the location of the target device; the moving speed of the data acquisition device 10A; weather information such as the presence and strength of wind, weather, etc.; temperature; etc.

[0060] The calculation of the power consumption based on the weather information can be performed, for example, as follows. As a specific example, compared to when the weather is clear, when there is rain, snow, sleet, hail, thunder, typhoon, fog, wind (for example, the wind speed is 10 m / s or more, 15 m / s or more, 20 m / s or more, 25 m / s or more, 30 m / s or more, the wind direction is the opposite direction (headwind) to the moving direction of the data acquisition device 10A), it takes longer for the data acquisition device 10A to move from the waiting location to the position of the target device. For this reason, in such weather conditions, the operation time determination unit 19 may relatively overestimate the power consumption of (1). Specifically, the operation time determination unit 19 can add, for example, an arbitrary ratio to the calculated value. The arbitrary ratio is not particularly limited, and can be set to, for example, 3%, 5%, 10%, 15%, etc., with the total amount of power of the battery unit 15 being 100%.

[0061] The calculation of the power consumption based on the temperature can be performed, for example, as follows. As a specific example, in a relatively low temperature (for example, 10°C or less, 5°C or less, or 0°C or less) or relatively high temperature (for example, 27°C or more, 30°C or more, 35°C or more, 40°C or more) environment, the power efficiency of the battery unit 15 decreases. For this reason, in such temperature conditions, the operation time determination unit 19 may relatively overestimate the power consumption (1). Specifically, the operation time determination unit 19 can add, for example, an arbitrary ratio to the calculated value. The arbitrary ratio is not particularly limited, and can be set to, for example, 3%, 5%, 10%, 15%, etc., with the total amount of power of the battery unit 15 being 100%.

[0062] Furthermore, since it is expected that it will take time to search for the target device during the first movement from the standby location to the location of the target device, the operation time determination unit 19 may relatively overestimate the power consumption amount of (1). Specifically, for example, when calculating the power consumption amount of (1) during the first movement, the operation time determination unit 19 can add an arbitrary percentage to the calculated value of the power consumption amount of (1). The arbitrary percentage is not particularly limited, and can be set to, for example, 3%, 5%, 10%, 15%, etc., with the total amount of power of the battery unit 15 being 100%.

[0063] The operation time determination unit 19 may allocate, as the amount of power in (2), for example, an arbitrary ratio of the total amount of power stored in the battery unit 15, or may allocate a value calculated for the amount of power consumed in the data acquisition process. In the former case, the operation time determination unit 19 may set, as the amount of power in (2), the total amount of power in the battery unit 15 as 100%, and, for example, the amount of power consumed per 30 minutes of operation time as 10%. In the latter case, the operation time determination unit 19 may allocate, as the amount of power in (2), a value calculated for the amount of power consumed based on, for example, the amount of power consumed while the data acquisition device 10A is in standby during the acquisition of the data; the amount of power consumed by wireless communication by the data acquisition unit 16; and the like. In addition, when the wireless power supply process and the storage process are performed in parallel with the data acquisition process, the amount of power consumed when storing data in the storage unit 17 may be taken into consideration. In addition, the amount of power consumed may be calculated based on weather information such as weather; temperature; and the like, similar to the amount of power in (1).

[0064] The operation time determination unit 19 may allocate, as the amount of power in (3), for example, an arbitrary ratio to the total amount of power stored in the battery unit 15, or may allocate a value calculated by calculating the amount of power consumed by supplying power to the target device in the wireless power supply process. In the former case, the operation time determination unit 19 may set, as the amount of power in (3), the total amount of power in the battery unit 15 as 100%, and may set, for example, the amount of power consumed per 30 minutes of operation time as 70%. In the latter case, the operation time determination unit 19 may determine, as the amount of power in (3), for example, the amount of power consumed based on the amount of power required for the target device to read data in the storage unit and transmit it to the data acquisition device 10A. Also, similar to the amount of power in (1), the amount of power consumed may be calculated based on weather information such as weather, temperature, and the like.

[0065] The data transfer speed by wireless communication varies greatly depending on the environment. Therefore, the amount of power required in the wireless power supply process and the data acquisition process may greatly exceed the initial assumption. For this reason, the operation time determination unit 19 may set an upper limit on the size of data acquired in the data acquisition process or the time for performing the wireless power supply process (and the data acquisition process). In this case, the data acquisition device 10A of the present embodiment may terminate the process and transition to the second operation control process when either the size of the acquired data or the time for performing each process reaches the set upper limit. According to such a process, for example, it is possible to prevent the data acquisition device 10A from running out of battery before returning to the pre-specified location.

[0066] Next, steps S12 to S17 are carried out in the same manner as steps S12 to S17 in the data acquisition method of the first embodiment.

[0067] According to the data acquisition device 10A of this embodiment, the operating time of the data acquisition device is determined based on a parameter related to the amount of power stored in the battery unit 15 of the data acquisition device 10A, so that, for example, data of the target device can be acquired by efficiently using the power stored in the battery unit 15. Therefore, according to the data acquisition device 10A of this embodiment, for example, data in a disaster-stricken target device can be more efficiently restored.

The storage device 20 includes, for example, a central processing unit (CPU, GPU, etc.) 201, a memory 202, a bus 203, an input device 204, a display device 205, a communication device 206, a storage unit 26, and a position information transmission unit 23 including a battery unit 231. The individual units in the hardware configuration of the storage device 20 are connected to each other via the bus 203 by their respective interfaces (I / F).

[0071] The central processing unit (Central Processing Unit) 201 is responsible for the overall control of the storage device 20. In the storage device 20, the central processing unit 101 executes, for example, the program of the present invention and other programs, and also reads and writes various information. Specifically, for example, the central processing unit 201 functions as a disaster occurrence detection unit 21, a switching unit 22, a wireless power acquisition unit 24, a data reading unit 25, and a data transmission unit 27.

[0077] When the storage device 20 has the battery, the battery is supplied with power from an external power supply device, and supplies power to each unit in the storage device 20 that requires power. The battery is also charged, for example, by being supplied with power from an external power supply device. This allows the battery to supply power to each unit for a certain period of time even in a state where there is no power supply from the external power supply device. The battery may be supplied with power from the external power supply device by a non-contact power transmission method. The non-contact power transmission method is, for example, the same as described above.

As shown in Fig. 9, the communication base station 30 includes a data acquisition unit 31 and a data recovery unit 32, and may include, as an optional configuration, for example, a management unit 33 and / or an instruction information transmission unit 34. The communication base station 30 is, for example, the communication base station of the first and second embodiments.

[0079] 10 illustrates a block diagram of a hardware configuration of the communication base station 30. The communication base station 30 includes, for example, a central processing unit (CPU, GPU, etc.) 301, a memory 302, a bus 303, an input device 304, a display device 305, a communication device 306, and a storage device 307. Each part of the hardware configuration of the communication base station 30 is connected to each other via the bus 303 by each interface (I / F).

[0080] The central processing unit (Central Processing Unit) 301 is responsible for the overall control of the communication base station 30. In the communication base station 30, the central processing unit 101 executes, for example, the program of the present invention and other programs, and also reads and writes various information. Specifically, for example, the central processing unit 301 functions as a data acquisition unit 31 and a data recovery unit 32, and in the case where the communication base station 30 includes, for example, a management unit 33 and / or an instruction information transmission unit 34, it further functions as the management unit 33 and / or the instruction information transmission unit 34.

[0081] The bus 303 can also be connected to, for example, an external device. Examples of the external device include an external database, a printer, the data acquisition device of the present invention, and a communication base station. The communication base station 30 can be connected to the communication network by, for example, a communication device 306 connected to the bus 303, and can also be connected to an external device via the communication network.

[0082] An example of the memory 302 is a main memory (primary storage device). When the central processing unit 301 performs processing, the memory 302 reads various operation programs, such as the program of the present invention, stored in the storage device 307 described below, and the central processing unit 301 receives data from the memory 302 and executes the programs.

[0084] In the communication base station 30, the memory 302 and the storage device 307 can also store access information and log information from an administrator, as well as information acquired from an external database (not shown).

[0085] The communication base station 30 may further include, for example, an input device 304 and a display device 305. The input device 304 is, for example, a touch panel, a keyboard, a mouse, etc. The display device 305 is, for example, an LED display, a liquid crystal display, etc.

[0086] Next, an example of the data recovery method of this embodiment will be described with reference to the flowchart of FIG. 11. The data recovery method of this embodiment is implemented as follows, for example, using the data recovery system device 100 of FIG. 6. Note that the data recovery method of this embodiment is not limited to the use of the data recovery system device 100 of FIG. 6. In FIG. 11, the flowchart on the left side shows an example of the processing of the target device 20 (storage device 20), the flowchart in the center shows an example of the processing of the data acquisition device 10, and the flowchart on the right side shows an example of the processing of the communication base station 30. Note that in the following description, an example will be given in which the communication base station 30 has a management unit 33 and an instruction information transmission unit 34, but as described above, in the communication base station 30, the management unit 33 and the instruction information transmission unit 34 are of any configuration, and the present invention is not limited thereto.

[0087] First, the disaster occurrence detection unit 21 of the storage device 20 detects the occurrence of a disaster (S21, disaster occurrence detection step). The occurrence of a disaster may be detected, for example, by the storage device 20 acquiring disaster occurrence information (for example, an emergency earthquake alert, a tsunami warning, etc.) via the communication line network, or the disaster occurrence detection unit 21 may detect the occurrence of an earthquake, an occurrence of a fire, etc. In the latter case, for example, a known sensor such as a seismic intensity meter or a fire detector can be used as the disaster occurrence detection unit 21. The processing by the disaster occurrence detection unit 21 is not limited to these examples, and for example, the disaster occurrence detection unit 21 may detect the occurrence of a disaster by detecting a power interruption of the storage device 20 without relying on a normal power-off means. In this case, for example, a known power interruption detector can be used as the disaster occurrence detection unit 21.

[0088] When the occurrence of the disaster is detected, the storage device 20 uses the switching unit 22 to switch the storage device 20 from the normal mode to the emergency mode (S22, switching step). In the normal mode, the location information transmission unit 23, the data reading unit 25, and the data transmission unit 27 of the storage device 20 are stopped. On the other hand, when the occurrence of a disaster is detected and the storage device 20 is switched to the emergency mode, the location information transmission unit 23, the data reading unit 25, and the data transmission unit 27 of the storage device 20 are activated and wait for data reading and transmission.

[0089] Then, when the storage device 20 switches to the emergency mode, the location information transmission unit 23 uses the power stored in the battery unit 231 to transmit the location information of the storage device 20 to the external device (S23, location information transmission step). The external device is not particularly limited, and may be, for example, the data acquisition device 10, the communication base station 30, or an external device capable of communicating with these devices. The external device is, for example, as described above.

[0090] Next, the data acquisition device 10 carries out steps S11 to S13 in the same manner as steps S11 to S13 in the first embodiment.

[0091] Then, the storage device 20 acquires power from the outside (the data acquisition device 10) by a non-contact type power transmission method using the wireless power acquisition unit 24 (S24, wireless power acquisition step). The non-contact type power transmission method is, for example, as described above.

[0092] Next, the storage device 20 uses the power acquired by the wireless power acquisition unit 24 to read data for each disk in the memory unit 26 by the data reading unit 25 (S25, data reading step). The power acquired by the wireless power acquisition unit 24 may be directly supplied to the data reading unit 25, or, if the storage device 20 has the battery and the battery has not been damaged by the disaster, the wireless power acquisition unit 24 may temporarily store the acquired power in the battery and supply power from the battery to the data reading unit 24.

[0093] Next, the storage device 20 uses the power acquired by the wireless power acquisition unit 24 to transmit the read data to the data acquisition device 10 by wireless communication using the data transmission unit 27 (S26, data transmission step). The power acquired by the wireless power acquisition unit 24 may be directly supplied to the data transmission unit 27, or, if the storage device 20 has the battery and the battery has not been damaged by the disaster, the wireless power acquisition unit 24 may temporarily store the acquired power in the battery and supply power from the battery to the data transmission unit 27. The wireless communication is, for example, as described above.

[0094] Next, the communication base station 30 transmits instruction information related to data acquisition to the data acquisition device 10 by the instruction information transmitting unit 34 prior to S14 of the data acquisition device 10 (S31, instruction information transmitting step). The instruction information is as described above.

[0095] Then, the data acquiring section 16 of the data acquiring device 10 acquires the instruction information, and acquires data from the storage device 20 in accordance with the instruction information (S14, data acquiring step).

[0096] Next, the storage unit 17 of the data acquisition device 10 stores the acquired data as well as disk information about the disk on which the acquired data was stored (S15, storage step). The disk information includes, for example, identification information of the disk and information specifying an address (data storage area).

[0097] Next, in S16, the data acquisition device 10 is moved to a pre-designated location (S16, second operation control step). At this time, for example, the data acquisition device 10 charges the power of the battery unit 15 in preparation for the next data acquisition.

[0098] Next, the data transmission unit 18 of the data acquisition device 10 transmits, for example, the data and the disk information to the base station (S17, data transmission step). At this time, for example, identification information of the storage device 20 is also transmitted.

[0099] Then, the communication base station 30 acquires the data acquired by the data acquisition device 10 from the memory unit 26 of the storage device 20 by the data acquisition unit 31 (S32, data acquisition step). The data may be acquired by connecting the communication base station 30 and the data acquisition device 10 by wire or by wireless communication.

[0100] Next, the communication base station 30 uses the data recovery unit 32 to reconstruct the data stored in the memory unit 26 of the storage device 20 based on the acquired data (S33, data recovery step).

[0101] Then, the communication base station 30 manages the progress of data recovery based on the storage device information on the storage device 20 through the management unit 33 (S34, management step), and ends the process (END). The storage device information includes, for example, identification information of the storage device 20 from which the data acquisition device 10 acquired data, identification information of the disk on which the data was stored, the address on the disk where the data was stored, the size of the data, and other information.

[0102] Furthermore, in the data recovery method of this embodiment, for example, in the management step, S12, S13, S24 to S26, S31, S14 to S17, and S32 to S34 may be repeatedly performed until it is determined that data recovery of storage device 20 has been completed, that is, that recovery of all data stored in storage device 20 has been completed.

[0103] In the present embodiment, the data acquisition device 10 directly acquires the location information of the storage device 20, but the data recovery method of the present invention is not limited to this. In the data recovery method of the present invention, for example, the storage device 20 may transmit the location information of the storage device 20 to the communication base station 30. In this case, the communication base station 30 may transmit, for example, movement instruction information to the location of the storage device 20 to the data acquisition device 10, and the data acquisition device 10 may move to the location of the storage device 20 according to the movement instruction information. In this case, the communication base station 30 may transmit instruction information regarding the acquisition of the data to the data acquisition device 10 in addition to the movement instruction information.

[0104] According to the data recovery system device 100 of this embodiment, the data acquisition device 10 supplies power to the damaged storage device 20 by a non-contact power transmission method and can acquire data in the memory unit of the storage device 20 by wireless communication. Therefore, even if the power supply to the storage device 20 is cut off due to a disaster or the like, the information in the storage device 20 can be easily acquired. In the disaster area, for example, infrastructure facilities such as transportation means and communication means are often damaged, or it is often impossible to approach the location of the damaged target device. Even in such a case, the data acquisition device 10 can easily go to the disaster area and acquire data. Furthermore, since there is no need for workers to go to the disaster area, the safety of the workers is ensured. Therefore, according to the data recovery system device 100 of this embodiment, for example, data in the damaged target device can be easily restored.
