Description

  The present invention relates to an electronic device and a program having a function of backing up data.

  Conventionally, in an electronic device such as a mobile phone, when an impact is applied by accidentally dropping the electronic device itself, whether or not a failure has occurred due to the impact is self-diagnosed, Is known to inform the user to that effect (see, for example, Patent Document 1).

  In addition, in consideration of the occurrence of a failure due to a fall or the like, there is also known a technology for automatically backing up internal data by detecting in advance that the electronic device itself is in a state that may be damaged. Patent Document 2 discloses that a mobile phone is accidentally dropped or dropped in water by an acceleration sensor or a water wetting sensor, respectively, before falling on the ground or before water enters the inside of the device. It is described that data in the device is stored in a backup memory.

  In Patent Document 2 described above, the backup memory is a memory card that can be removed from the mobile phone, whereby the memory card is removed from the broken mobile phone, and the memory card is attached to a new device and backed up. It is configured so that it can be restored.

Japanese Patent Laid-Open No. 06-169285 JP 2005-346666 A

  However, although the technology of Patent Document 2 assumes a case where the mobile phone itself is actually broken due to the fall or submergence of the mobile phone, in reality, products with high impact resistance and water resistance are commercialized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First Embodiment FIG. 1 is a circuit block diagram of a mobile phone device 1 which is an example of an electronic apparatus of the present invention. In the figure, a central control unit (CPU) 2 controls the overall operation of the cellular phone device 1 in accordance with various programs stored in the storage unit 3.

  That is, the storage unit 3 is a program for executing various flowcharts to be described later, and an application program for executing applications of various functions such as a call function, an e-mail function, an Internet connection function, an address book function, and a schedule function. (Not shown) ROM (Read Only Memory) is stored, and the central control unit 2 controls the overall operation of the cellular phone device 1 based on a program stored in the ROM. The ROM of the storage unit 3 also stores a check program for determining whether or not the mobile phone device 1 operates normally, that is, whether a failure has occurred. The central control unit 2 Normal operation is determined according to the check program.

  In this case, the check program is a program that performs a high-level check such as determining whether or not the same operation as the initialization sequence performed at power-on is possible, whether or not the power supply voltage value is within the normal range, The pulse is provided with a program for performing a low-level check such as whether the frequency is in a normal range, and the central control unit 2 selects a check program according to the situation and determines normal operation.

  Further, the storage unit 3 is provided with a backup range storage unit that stores the backup range of which function data is backed up at the time of a backup operation described later, and temporarily stores various data. A random access memory (RAM) that operates as a work area is also provided.

  The radio communication unit (transmission / reception unit) 4 demodulates the radio signal of audio captured from the antenna 5 into a reception baseband signal when operating as a telephone call function, and then receives audio from the reception speaker 7 via the audio signal processing unit 6. Output. Also, the audio signal input from the transmission microphone 8 is processed by the audio signal processing unit 6 and then sent to the radio communication unit 4. The radio communication unit 4 encodes the audio signal into a transmission baseband signal, and then the antenna 5. To send out.

  Further, during the operation of the e-mail function, the Internet connection function, etc., it is possible to send / receive e-mails and browse websites via the antenna 5 and the wireless communication unit 4. It is sent to the display unit 9 and displayed.

  The display unit 9 is composed of, for example, a dot matrix type liquid crystal display device or an EL display device, and displays information necessary for the telephone device (information such as the other party's telephone number, radio wave reception state, remaining battery level, etc.) As described above, the contents of the e-mail and website are displayed. In the case of the address book function and schedule function, address book information (data such as name, address and telephone number) and schedule information (data such as schedule time and requirements) are displayed.

  The operation unit 10 is an operation key provided in the cellular phone device 1, and although not shown in detail, a power on / off key, a numerical character input key for inputting numerical information and character information, and various functions (applications) ) Keys for operating various functions such as various application keys for selecting activation and termination, on-hook keys for calls, and off-hook keys.

  The application information storage unit 11 stores information (data) related to various applications and is not specifically illustrated. For example, an address book information storage unit that stores address book information of an address book function, Storage areas such as a schedule information storage unit that stores schedule information, a mail information storage unit that stores transmission / reception mail information of the mail function, and a Web information storage unit that stores URL information of a Web site of the Internet function are provided.

  The application information storage unit 11 is also provided with a password number storage unit for storing a password number, which will be described later, and performs a backup operation when the mobile phone device 1 is detected to be in a special state. A backup setting flag 11F to be controlled is also provided. The backup setting flag 11F will be described later.

  The backup memory 12 is composed of a non-volatile memory that can be written and read, such as a flash ROM, and is configured as a memory card that can be attached to and detached from the mobile phone device 1. As will be described later, this backup memory 12 sequentially stores information (data) of various applications stored in the application information storage unit 11 when the backup function of the mobile phone device 1 operates. Functions as a destination memory.

  The data related to various applications written in the backup memory 12 differs depending on the level of the special state detected by the special state detection unit 13 described later. For example, the level of the special state is low and the data of the mobile phone device 1 is low. When the possibility of damage is low, only the data of the address book function, mail function and schedule function is written as backup data, and when the level of special state is high and the possibility of damage of the mobile phone device 1 is high, all data is written. Similarly, the backup function or data range is stored in advance in the program storage area of the storage unit 3.

  However, the special state detection unit 13 is a detection circuit with a sensor (not shown) that detects whether or not the mobile phone device 1 itself is in a special state. For example, the special state detection unit 13 includes a triaxial acceleration sensor and is portable. Detecting that the telephone device 1 itself is falling, detecting a state in which the mobile phone device 1 is immersed in water with a water wetting sensor (a state in which moisture may be immersed in the device), A temperature sensor is provided to detect that the environment surrounding the mobile phone device 1 is abnormally high (for example, left in direct sunlight for a long time) or low in temperature (for example, left in snow). .

  The power supply unit 14 includes a rechargeable secondary battery (not shown) and a backup battery that supplies a backup voltage to each circuit unit when the battery voltage of the secondary battery decreases. A drive voltage is supplied.

  As described in FIG. 2, the backup setting flag 11F of the application information storage unit 11 described above is set to “1” without performing the backup operation when the value is set to “0”. In some cases, data to be backed up is stored in a backup memory 12 mounted on the device.

  When the value of the backup setting flag 11F is set to “2”, data to be backed up to a network memory such as a server provided in advance on the network via the wireless communication unit 4 and the antenna 5 For this reason, although not shown in the figure, a destination telephone number, e-mail address, website URL, or the like is preset in a storage area (not shown) of the application information storage unit 11. Has been.

  The operation of the mobile phone device 1 configured as described above will be described with reference to the flowcharts of FIGS.

  Although not described in the flowcharts of FIGS. 3 and 4, the mobile phone device 1 is normally in a standby state, and an incoming call notification is made when there is an incoming voice call or mail. Then, in the case of a voice call, a call with the other party can be made by operating an off-hook key. When a mail is received, the received mail content is displayed on the display unit 9.

  On the other hand, when the Internet connection function is operated, the website can be browsed via the antenna 5 and the wireless communication unit 4, and when the address book function and the schedule function are operated, the address book information (name, address and telephone number). Number, etc.) and schedule information (schedule time, requirements, etc.) are displayed on the display unit 9.

  Further, the telephone number input for making a call, the data entry for the address book and schedule, the key input for creating the mail text in the mail function, etc. are all performed by the key input on the operation unit 10.

  However, when the mobile phone device 1 is in a special state as described above, the backup setting flag 11F is set in accordance with whether or not the data stored in the application information storage unit 11 is to be backed up in advance. Keep it.

  That is, as described with reference to FIG. 2, when it is not necessary to back up data, the backup setting flag is set to “0” by key input on the operation unit 10 and the backup memory 12 performs data backup. Is set to “1” when backing up to a network memory such as a server provided in advance on the network via the wireless communication unit 4 and the antenna 5.

  In such a state, the central control unit 2 always performs detection of the special state shown in FIG. 3 as an interrupt process at a predetermined timing.

  In the process of FIG. 3, step S1 is performed when the special state detection unit 14 detects that the mobile phone device 1 is in a special state as described above and when it is in a special state. The level is judged.

  That is, for example, when the mobile phone device 1 is dropped, if the value of the signal indicating the acceleration from the acceleration sensor of the special state detection unit 14 is equal to or greater than a specific threshold, it is determined that the state is a special state. The level of the special state is determined based on whether the value of the acceleration signal exceeding the threshold value is larger or smaller than a predetermined specific value.

  In the next step S2, it is determined whether application processing of some other function is being executed (working) at this time.

  For example, if the mobile phone device 1 is dropped while the mail function application is running and a mail text is being created, it is determined that the operation is in progress in the above step S2, so that the next step S3 is performed. Then, the application data storage unit 11 temporarily saves the data being worked on up to that point, that is, the mail text created so far.

  In the next step S4, the active application, in the above example, the mail function application is stopped (paused), and in the next step S5, the backup setting flag 11F is read.

  If it is detected in step S1 that a special state has occurred, if no application is running, the process proceeds directly from step S2 to step S5.

  In step S6 after step S5, it is determined whether or not the value of the backup setting flag 11F is greater than “0”, ie, “1” or “2”.

  If it is “1” or “2”, the process proceeds to step S7, and the range to be backed up is specified according to the level of the special state detected in step S1. That is, as described above, when the level of the special state in the special state is low and the possibility of damage to the mobile phone device 1 is low, only the data of the address book function, mail function and schedule function are specified as the backup range, and the level of the special state When the mobile phone device 1 is highly likely to be damaged, all data is specified as the backup range.

  In the next step S8, the specified range of data is encrypted and stored in the work area of the storage unit 3. In this case, the encryption is performed using the password stored in the password number storage unit of the application information storage unit 11, and the encrypted data is decrypted by the input of the password and the original data is deleted. It can be restored to the data.

  The next step S9 is backup processing, and a detailed flow is shown in FIG. In FIG. 5, step A1 reads the backup setting flag 11F, and in the next step A2, it is determined whether or not the value of the backup setting flag 11F is “1”.

  If the value of the backup setting flag 11F is “1”, the process proceeds to step A3, where the encrypted data stored in the work area in step S8 of FIG. The flow of the backup process is exited, and the process proceeds to step S10 in FIG.

  On the other hand, if the value of the backup setting flag 11F is not “1” in step A2 in FIG. 5, the value is “2”. In this case, the process proceeds to step A4, and the encrypted data is displayed. The data is transmitted to and stored in a network memory which is a predetermined external storage destination such as a server on the network via the wireless communication unit 4 and the antenna 5. Then, it progresses to step S10 of FIG.

  Step S10 in FIG. 3 determines whether or not the cellular phone device 1 has returned from the special state to the normal state. For example, when the acceleration signal from the acceleration sensor is lost, the special state ends and the normal state is completed. When it is determined that the state has been returned, and this determination is made, the process proceeds to step S11 in FIG.

  In step S11, a check program corresponding to the level of the special state is executed. If the level of the special state is high, it is determined whether or not the same operation as the initialization sequence performed when the power is turned on is possible. If the special state level is low, the power supply voltage value is in the normal range, and the clock pulse is in the normal range frequency. In step S12, it is determined whether or not the operation is normal.

  In step S12, if the operation is not normal, this flow is immediately terminated as a failure has occurred, but if it is determined that the operation is normal and no failure has occurred, the next backup destination in step S13 Proceed to the data deletion process.

  FIG. 6 is a detailed flow of the backup destination data deletion processing in step S13. First, in step B1, the value of the backup setting flag 11F is read, and whether or not the value is “1” in the next step B2. That is, it is determined whether it is “1” or “2”.

  If the value of the backup setting flag 11F is “1”, the backup data is stored in the backup memory 12 in step A3 of FIG. 5, so that it is stored in the backup memory 12 as backup data in step B3 of FIG. The stored data is deleted from the backup memory 12, and the flow goes through the backup process to proceed to step 14 in FIG.

  On the other hand, if the value of the backup setting flag 11F is “2” in step B2 of FIG. 6, the process proceeds to step B4, and the backup data transmitted to the external storage destination in step A4 of FIG. After the deletion command is transmitted to the storage destination, the process proceeds to step 14 in FIG.

  In step S14 of FIG. 4, it is detected that there is an application that was running when the special state was detected in step S2 of FIG. 3, and the data at that time is temporarily stored in the next step S3, and further in step S4. It is determined whether or not there is an application set in the sleep mode.

  If such an application does not exist, this flow ends. However, if there is a suspended application, for example, if a special state is detected during the operation of the mail function as described above, step S15 is performed. The flow is finished after returning to a state where the application set in the sleep mode can be resumed from the pause time.

  As described above, according to the above-described embodiment, the acceleration sensor or the environmental sensor detects that the device itself is in a special state such as falling or in an abnormal environment, and as a result, the backup function is activated and the data is for backup. Even when stored in the memory, if the electronic device is operating normally, the backup data stored in the backup memory is deleted, so that the risk of information leakage can be reduced.

  The memory that can be attached to and detached from the mobile phone is not only used as a backup memory for storing backup data as described above, but also information on various applications, for example, Web image information, captured image information if a camera function is provided, etc. Is often used as a memory for storing. In this case, in the above embodiment, the backup data is deleted on condition that the electronic device operates normally as described above, so that it is possible to prevent the storage capacity from being used unnecessarily for backup. it can.

  It is possible to select the memory that can maintain the most confidentiality because it can be selected from a plurality of memories such as a memory installed in the device as a backup memory and a memory stored through communication. is there.

  In addition, if the electronic device does not operate normally after the occurrence of a special state, data backup is performed, and if it operates normally, it can return to the state when the special state was detected. , You can use the most useful depending on the situation.

  Further, since the backup is stored as encrypted data, not only can the confidentiality of the data be ensured, but also the original data can be easily restored by the password.

Second Embodiment FIG. 7 is an operation flowchart according to a second embodiment of the present invention. In the second embodiment, the flowchart of FIG. 4 of the first embodiment is a flowchart as shown in FIG. 7, and all other configurations are the same as those of the first embodiment. Detailed explanations are omitted.

  However, in step S11 of FIG. 7, a device operation check corresponding to the special state level is performed, and if normal operation is detected in the next step S12, the process proceeds to step S20.

  In step S20, internal data of the mobile phone device 1, that is, information (data) of various applications stored in the application information storage unit 11 of FIG. 1, that is, e-mail data, address book information (name, address and (Data such as telephone numbers) and schedule information (data such as schedule time and requirements) are checked respectively. In the next step S21, whether or not all internal data is normal as a result of the check, that is, destruction of data. Or the like is determined.

  If it is determined in step S21 that the internal data stored in the application information storage unit 11 is normal, the process proceeds to step S22. This step S22 determines whether or not the backed up data exists in the backup destination memory.

  In this case, if the backup destination memory is the backup memory 12, it is determined whether or not the data exists in the area designated as the backup data storage area of the backup memory 12.

  If the backup destination memory is a network memory, an inquiry is made as to whether or not the transmitted backup data is stored, and a determination is made based on the answer.

  Then, if the backed up data does not exist in the backup destination memory, the process proceeds to step S14. If the backed up data exists in the backup destination memory, the process proceeds to step S13, and the flowchart shown in detail in FIG. To delete the backup data stored in the backup destination memory.

  That is, when it is determined in step S12 that the device operation is normal, the unconditionally backed up data as shown in FIG. 4 of the first embodiment is not deleted, but the original internal data is deleted. Is deleted after determining that is normal.

  On the other hand, if it is determined in step S21 that the internal data stored in the application information storage unit 11 is not normal, it is determined in step S23 whether backup data is stored in the backup destination, and the backup data is If it is determined that the data is stored, it is determined in step S24 whether the backup data is normal.

  If it is determined that the backup destination data is normal, the process advances to step S25 to write the backup destination data into the application information storage unit 11. That is, even if it is determined in steps S20 and S21 that the internal data stored in the application information storage unit 11 is not normal, if the backup destination data is normal, the backup destination normal data is determined in step S25. Is used to update the internal data of the application information storage unit 11.

  In this case, since the encrypted backup data is stored in the backup destination memory, the encrypted backup data is decrypted into the original data and stored in the application information storage unit 11. After normal data is written in the application information storage unit 11 in this way, the process proceeds to step S13, and the backup destination data is deleted.

  If the backup destination data is not normal in step S24, the process proceeds to step S26. The reason for reaching step S26 is that although there is no abnormality in the operation of the device in step S12, it is detected in step S21 that there is an abnormality in the internal data stored in the application information storage unit 11, and step S24. This is a case where it is detected that there is also an abnormality in the backup destination data.

  Accordingly, in step S26, a message indicating that there is no problem in the operation of the device or that a failure has not occurred, a message indicating that an abnormality has occurred in the internal data stored in the device, and a backup destination 1 is displayed on the display unit 9 shown in FIG. 1, respectively, indicating that an abnormality has also occurred in the data in FIG. 1 or that backup has not been performed normally.

  However, after completion of the processing in step S26 or when backup data does not exist at the backup destination in step S23, the process proceeds to step S14.

  If it is determined in step S12 that the device operation is not normal, the process proceeds to step S27. Steps S27 to S30 are the same processes as steps S20, S21, S22 and S13 described above, that is, it is determined that the internal data is normal (step S28: YES), and the backup destination is set. If it is determined that there is data (step S29: YES), the backup destination data is deleted in step S30.

  After the backup destination data is deleted in step S30 or when backup data does not exist in the backup destination in step S29, the process proceeds to step S31.

  In step S31, in response to the detection that the device does not operate normally in step S12 and step S28 and that the internal data stored in the application information storage unit 11 is normal, the display unit 9 In addition, a message that there is a problem in the operation of the device or that a failure has occurred and a message that there is no abnormality in the internal data stored in the device are displayed.

  If it is determined in step S28 that the internal data is not normal, the process proceeds to step S32. In step S32 and next step S33, similarly to step S23 and step S24, it is determined whether backup data is stored in the backup destination in step S32, and whether backup data in the backup destination is normal in step S33. Is to judge.

  If it is determined in step S32 that the backup data is stored in the backup destination and if it is determined in step S33 that the backup data is normal, the process proceeds to step S34, and a message indicating that there is a problem with the device operation, the internal of the device A message indicating that the data is abnormal and a message indicating that the backup data at the backup destination is normal are displayed on the display unit 9.

  If it is determined in step S33 that the backup destination data is not normal, the process proceeds to step S35, and a message indicating that there is a problem with the device operation, a message indicating that the internal data of the device is abnormal, and backup data at the backup destination are also displayed. A message indicating that there is an abnormality is displayed on the display unit 9.

  Further, if it is determined in step S32 that backup data is not stored in the backup destination, the process proceeds to step S36, a message indicating that there is a problem with the device operation, and that backup data is not stored in the backup destination. Is displayed on the display unit 9.

  In the second embodiment that operates as described above, the following effects are obtained in addition to the effects obtained in the first embodiment.

  First, after the backup process, the backup data at the backup destination is deleted after determining whether the data stored in the application information storage unit 11 that is the original data of the backup is normal. Even if it is erased, the original data can be ensured, and data leakage due to backup data can be prevented.

  In addition, even if the data stored in the application information storage unit 11 that is the original data of the backup is not normal, if the backup data at the backup destination is normal, the backup data is the application that is the original data of the backup Since the information is stored in the information storage unit 11, the original data can be reliably secured even if the backup data is deleted.

  In the second embodiment, the user is provided with the optimum information because the operation status of the device, the status of the original data, the backed-up data, etc. is displayed in accordance with the operating status after the special status is detected. be able to. The user can use it as a material for determining whether or not to request repair from a manufacturer or the like, and how to handle backup source data and backup destination data.

  Also, the special status detection is divided into multiple levels, and depending on the level, the backup range is different and the operation check of different devices is performed. Can be made as light as possible.

  In the above embodiment, one of the removable backup memory 12 and the network memory is selected as the backup destination memory. For example, a non-volatile fixed memory is provided inside the device to backup it. The memory may be selected, or a plurality of detachable nonvolatile memories may be provided, and one of them may be selected as the backup memory.

  Further, instead of using one of the plurality of memories as a backup memory, for example, a plurality of memories may be used as backup memories, and backup data may be written to each of them. In this case, the same data may be sequentially stored in a plurality of backup memories, or different data may be sequentially stored for each memory.

  Even in such a case, if it is determined that the device operates normally after the special state, or if it is determined that the backup source data is normal, the data is stored in each backup memory. Needless to say, a configuration is adopted in which deleted data is deleted.

  In consideration of the occurrence of a failure during backup, priorities may be assigned to each application and data, and backups may be sequentially performed according to the priorities.

  Further, in each of the above embodiments, the example in which the present invention is applied to the mobile phone device 1 has been described. However, the present invention can be applied to any electronic device such as a digital camera, a personal computer, a music player, and a PDA. It is.
