Description

  The present invention relates to an information terminal and a system.

  In recent years, with the spread of network environments and network-compatible devices, a client-server system has been proposed in which a client communicates with a network-connected server to perform processing.

  As an example, information is stored in the server, the user operates the client to communicate with the server, and the client obtains a response by obtaining information from the server or processing the information from the server, and outputs it to the user There is a way to do it. In this case, since the client does not save the information, even if the client becomes unusable due to failure, loss, theft, etc., the information is not lost. Further, the user can obtain and process the same information using an arbitrary client. In addition, since the server collectively manages information, information synchronization, backup, restoration, and the like are facilitated.

  However, in the case of the above example, if communication with the server becomes impossible due to a malfunction of the network environment or a failure of the server, the information cannot be viewed or processed by the client.

  In order to solve this, there is a method described in Patent Document 1 as one method.

Patent Document 1 describes that “provides a method for browsing information of a server device even when the network is disconnected” (see paragraph 0011). In Patent Document 1, a RAM for storing screen data is mounted in a client device, and screen data sent from the server device to the client device is stored when the network between the client device and the server device is good. Even when the network is disconnected, the screen data stored in the client device can be browsed. By saving the data in the RAM, the screen data is erased when the client device is powered off or the operation system is shut down, so that security can be ensured. Is described.

JP 2009-122879 A

  However, in Patent Document 1, no consideration is given except that the client displays past screen data provided from the server. For example, when the client and the server cannot communicate due to an earthquake disaster or the like, it is necessary for the client to be able to execute new processes such as emergency contact and information collection without the server in addition to the screen data display.

  On the other hand, emergency information such as emergency contact information and communication lines for collecting emergency contact and emergency information are normally viewed and used for privacy protection, private use prevention, or mischief prevention. It is necessary to restrict access so that it cannot be done. In addition, since it is necessary to consider that a malicious user may intentionally stop the communication function, it cannot be determined that there is an emergency only by not being able to communicate with the server.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information terminal and a system that enable appropriate failure handling even when communication with a server becomes impossible. is there.

  In order to solve the above problems, for example, the configuration described in the claims is adopted.

  According to the present invention, it is possible to provide an information terminal and a system that enable appropriate failure handling even when communication with a server becomes impossible in a client-server type system.

  Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. Further, the present invention is not limited to the illustrated example.

  A first embodiment according to the present invention will be described with reference to FIGS.

  In this embodiment, the client is a client-server type system that performs processing by communicating with a server connected to a network, and enables appropriate failure handling even when communication with the server becomes impossible. The failure handling information terminal and system will be described.

  FIG. 1 is a diagram illustrating a configuration example of a failure handling system according to the present embodiment. Here, a case where the failure handling system according to the present embodiment is applied to an education support system will be described as an example. The education support system improves the quality of education by using digitized teaching materials, sharing teaching plans among teachers, managing grades and learning histories, etc. This reduces the burden on A child, student, or teacher operates a client to obtain data from a school server connected to a network, or request processing from the school server.

  The education support system according to this embodiment includes a learner's terminal 1, an administrator's terminal 2, a school network 3, a school server 4, a mobile phone network 5, a mobile phone communication server 6, an external network 7, an external server 8, an emergency A contact terminal 9 is included. As an example of the failure handling information terminal, description will be given using the learner's terminal 1 and the administrator's terminal 2.

  The learner's terminal 1 is a terminal intended for use by learners such as children and students. In normal times, it operates as a terminal that supports the learning of the learner in cooperation with the school server 4 and the manager terminal 2, and in an emergency, it operates as a terminal that performs emergency contact independently.

  The manager terminal 2 is a terminal that is assumed to be used by a manager such as a teacher. In normal operation, it operates as a terminal that supports management of the learner by the administrator in cooperation with the school server 4, and in emergency, it operates as a terminal that supports control of the learner terminal 1 and emergency communication of the learner.

  The school network 3 is a local network in which connectable terminals are limited. The learner's terminal 1 and the administrator's terminal 2 are registered in advance so that they can be connected to the in-school network 3, and registration information is recorded in the school server 4. In a normal state, the learner's terminal 1 and the manager's terminal 2 can communicate via the school network 3. However, since the connection with the school network 3 is cut off at the time of a power failure, equipment failure, or network abnormality, these cannot communicate via the school network 3. In preparation for such a case, the learner's terminal 1 and the administrator's terminal 2 switch the setting of the communication method of each terminal to perform communication via the mobile phone network 5 without going through the school network 3. And communication means for emergency contact.

  The school server 4 performs management information on the external network 7 such as registration of terminals that can be connected to the school network 3, management information of the school network 3, information related to the education support system, registration of terminals that can access the external network 7, etc. Hold etc. Connection to the school server 4 is permitted only to terminals that are permitted to connect to the school network 3. Moreover, access authority differs for each terminal according to information. For example, the administrator terminal 2 can rewrite the grade information of all the terminal users, but the learner terminal 1 can be set to be inaccessible except for browsing the terminal user's own grade information. it can.

  The cellular phone network 5 is a network for cellular phone communication, which is different from the school network 3. The learner's terminal 1 and the administrator's terminal 2 are registered in advance so that they can be connected to the mobile phone network 5, and registration information is recorded in the mobile phone communication server 6. In addition to communication for voice calls, data communication such as video information and text information is also performed through this line.

  The external network 7 is a wide area network such as the Internet. The learner's terminal 1 and the administrator's terminal 2 are connected to the external network 7 via the school server 4 or the mobile phone communication server 6.

  The external server 8 is a server that distributes emergency warnings such as earthquake early warnings and tsunami warnings distributed by the Japan Meteorological Agency to terminals. Various emergency information is delivered to the terminal by being transferred directly to the learner's terminal 1 and the administrator's terminal 2 or transferred to the school server 4 and the mobile phone communication server 6.

  The emergency contact terminal 9 is a partner-side terminal with which the user of the learner's terminal 1 contacts in an emergency. For example, there are mobile phone terminals owned by parents and telephone terminals at home. In the present embodiment, the example in which the mobile phone network 5 is connected is described. However, the emergency contact terminal 9 may be connected to another network other than the mobile phone network 5. For example, the emergency contact terminal 9 may be connected to the fixed telephone network, and may be connected to the portable telephone network 5 via the portable telephone communication server 6 connected to the fixed telephone network.

  When it is necessary to distinguish between one learner's terminal 1 and another learner's terminal 1, one may be described as a learner's terminal 1 a and the other as a learner's terminal 1 b. Similarly, when distinguishing between the manager terminal 2 and the other manager terminal 2, one may be represented as the manager terminal 2a and the other as the manager terminal 2b.

  If there is no mode transition condition in Step 2002 (No in Step 2002), or if server communication is not possible in Step 2003 (Yes in Step 2003), the mode transition unit 111 transitions to the emergency mode (Step 2004), the mode transition determination process ends.

  When there is no emergency information in Step 2001 (No in Step 2001), or when server communication is possible in Step 2003 (No in Step 2003), the mode transition unit 111 does not perform mode transition and determines mode transition. The process ends.

  FIG. 6 is a flowchart illustrating an example of mode transition determination processing in the emergency mode in the mode transition unit 111.

  In FIG. 6, when the mode transition unit 111 performs the mode transition determination process in step 1005 of FIG. 4, the process starts in the emergency mode. First, the mode transition unit 111 inquires of the emergency information receiving unit 109 whether there is emergency release information (step 3001).

  When there is emergency release information in Step 3001 (Yes in Step 3001), the mode transition unit 111 inquires of the emergency information reception unit 109 whether or not there is a mode transition condition for the emergency release information (Step 3002).

  When there is a mode transition condition in Step 3002 (Yes in Step 3002), the mode transition unit 111 inquires of the communication status monitoring unit 110 whether or not server communication is possible (Step 3003).

  If there is no mode transition condition in Step 3002 (No in Step 3002), or if server communication is possible in Step 3003 (Yes in Step 3003), the mode transition unit 111 transitions to the normal mode (Step 3004), the mode transition determination process is terminated.

  If there is no emergency information in Step 3001 (No in Step 3001), or if server communication is not possible in Step 3003 (No in Step 3003), the mode transition unit 111 does not perform mode transition and determines mode transition. The process ends.

The “confirmation date and time” and “server communication status” are acquired and updated by the communication status monitoring unit 110 when communication processing with the school server 4 is executed.

  “Confirmation date” represents the date and time when the communication status is confirmed. “Server communication status” indicates whether communication with the school server 4 is possible or not.

  FIG. 9 is a flowchart illustrating an example of emergency contact communication processing in the emergency contact communication unit 112.

  When detecting the user's operation (emergency contact start) in the input unit 102, the control unit 105 receives the detected content as an event (step 4001).

  Next, the emergency contact communication unit 112 inquires of the mode transition unit 111 whether or not the mode is an emergency mode (step 4002).

  If the emergency mode is set in step 4002 (Yes in step 4002), the emergency contact communication unit 112 causes the display unit 101 to display a learner selection screen (step 4003).

  Next, when a user operation (learner selection) is detected in the input unit 102, the control unit 105 receives the detected content as an event (step 4004).

  Next, the emergency contact communication unit 112 displays an emergency contact address screen on the display unit 101 for the learner selected in step 4004 (step 4005), and then performs emergency contact communication if necessary (step 4006). The emergency contact communication process is terminated.

  When it is not the emergency mode in Step 4002 (No in Step 4002), the emergency contact communication unit 112 displays an emergency contact start operation refusal screen on the display unit 101 (Step 4007), and ends the emergency contact communication process.

  FIG. 13 is an example of an emergency contact start operation rejection screen on the learner's terminal 1. The emergency contact start operation rejection screen is a screen that the emergency contact communication unit 112 displays on the display unit 101 in step 4007 of FIG. If the mode is not emergency mode, the user is informed that emergency communication such as telephone or e-mail cannot be made.

  FIG. 14 is a flowchart illustrating an example of emergency information distribution processing in the emergency information distribution unit 213.

  When detecting the user's operation (emergency information distribution start) in the input unit 102, the control unit 105 receives the detected content as an event (step 5001).

  Next, the emergency information distribution unit 213 causes the authentication unit 107 to authenticate the user and inquires about the authentication result (step 5002).

  If the authentication is successful in Step 5002 (Yes in Step 5002), the emergency information distribution unit 213 displays a distribution content setting screen on the display unit 101 (Step 5003).

  Next, when a user operation (distribution content setting) is detected in the input unit 102, the control unit 105 receives the detected content as an event (step 5004).

  Next, the emergency information distribution unit 213 stores the distribution content set in step 5004 in the storage unit 104 (step 5005), and causes the communication unit 106 to send the learner's terminal 1 according to the stored distribution content. The emergency information is distributed to the user (step 5006). Thereafter, the distribution result screen is displayed on the display unit 101 (step 5007), and the emergency information distribution process is terminated.

  If the authentication fails in Step 5002 (No in Step 5002), the emergency information distribution unit 213 displays a distribution start operation rejection screen on the display unit 101 (Step 5008), and ends the emergency contact communication process.

  As described above, the administrator terminal 2 is determined to deliver emergency information to the learner terminal 1 which is another terminal on the condition that the user authentication is successful. Therefore, it is possible to prevent the emergency information from spreading unnecessarily or inappropriately.

  FIG. 15 is an example of emergency information distribution information managed by the emergency information distribution unit 213.

  The emergency information distribution information includes information such as “learner ID”, “learner name”, “terminal ID”, “contact means”, “permission operation”, and “distribution status”. The “user ID”, “learner name”, “terminal ID”, “contact means”, “permission operation”, and “distribution status” are information stored and managed in advance in the school server 4 in a normal time. The communication unit 106 receives the information, and the emergency information distribution unit 213 acquires the information, stores it in the storage unit 104, and updates it.

  “Learner ID” represents the identification number of the learner. The “learner name” represents the name of the learner. The “terminal ID” represents the identification number of the learner terminal 1 being used by the learner. The “contact means” represents a communication means used for emergency contact of the learner. The “permitted operation” represents an operation permitted for the learner's emergency contact information. The learner ID “1” in FIG. 15 is permitted to “display phone numbers and telephone calls”, and the learner ID “2” is permitted to display “email addresses only, not send mail”. The learner ID “3” and the learner ID “4” indicate that the permission operation is not set. “Distribution status” indicates whether the emergency information has been distributed, has not been distributed, or does not require distribution.

  FIG. 16 is an example of a delivery content setting screen on the manager terminal 2. The distribution content setting screen is a screen that the emergency information distribution unit 213 displays on the display unit 101 in step 5003 of FIG.

  The “learner name”, “contact means”, and “permission operation” in FIG. 16 are the same as those in FIG. “Distribution presence / absence” indicates whether or not emergency information distribution is performed. The “learner name” and “contact means” display the contents of emergency information distribution information managed by the emergency information distribution unit 213, and “distribution presence / absence” and “permission operation” are displayed on the administrator terminal 2. This is a field that is input and set by the user.

  When the user selects “completion of setting” in the state of FIG. 16, the emergency information distribution information is in the state of FIG.

  FIG. 17 is an example of a distribution result screen in the manager terminal 2. The distribution result screen is a screen that the emergency information distribution unit 213 displays on the display unit 101 in step 5007 of FIG.

  The “learner name”, “contact means”, and “permission operation” in FIG. 17 are the same as those in FIG. 15, and the contents of the emergency information distribution information managed by the emergency information distribution unit 213 are displayed. . “Delivery result” is a column indicating whether the emergency information has been successfully delivered, failed or not delivered.

  FIG. 17A is in the middle of distribution, and the emergency information has been successfully distributed to the learner terminal 1a being used by “Hitachi Ichiro”, and the emergency information is being distributed to the learner terminal 1b being used by “Taro Ibaraki”. Represents an incomplete state.

  FIG. 17B shows that both the distribution of the emergency information to the learner terminal 1a used by “Hitachi Ichiro” and the learner terminal 1b used by “Taro Ibaraki” are completed. Both represent a successful state.

  FIG. 18 is an example of a distribution start operation refusal screen on the manager terminal 2. The distribution start operation rejection screen is a screen that the emergency information distribution unit 213 displays on the display unit 101 in step 5008 of FIG. If the user of the administrator terminal 2 is not authenticated as an administrator, the user is informed that emergency information cannot be distributed.

  As described above, according to the present embodiment, it is possible to provide a failure handling information terminal and system that enable appropriate failure handling even when communication with a server becomes impossible in a client-server system.

  For example, if it is applied to a client-server type education support system in which a client communicates with a server connected to a network and performs processing, the emergency contact information and the emergency contact communication function are usually protected for privacy, Private use prevention or mischief prevention is possible, and even if a malicious user intentionally stops the communication device, it can respond appropriately, and in the event of an emergency, emergency contact display and emergency communication function Can be used.

  In addition, for example, even when a power failure occurs due to an earthquake, the school wireless LAN router or the school server stops operating, and communication between the terminal and the school server 4 becomes impossible, the battery supplies power to the terminal, Emergency communication can be performed via a communication path terminal for a mobile phone equipped with a battery.

  Further, by making the administrator terminal 2 available as the learner terminal 1, even if the administrator terminal 2 breaks down due to, for example, a disaster, the administrator uses the learner terminal 1 that is operating normally. Can perform predetermined authentication and operate as the administrator terminal 2. Therefore, a more reliable failure response can be expected.

  In this embodiment, the case where the present invention is applied to an education support system has been described as an example. However, other systems such as a sales person support system in a company may be used.

  A second embodiment according to the present invention will be described with reference to FIGS.

  In the present embodiment, the administrator terminal 2 determines the operation mode of the learner terminal 1, the administrator terminal 2 instructs the learner terminal 1 to shift the operation mode, and the learner terminal 1 A case where the operation mode is changed in accordance with the mode change instruction will be described.

  FIG. 19 is a diagram illustrating a configuration example of the learner's terminal 1. The difference from FIG. 2 of the first embodiment is that the emergency information receiving unit 109 and the communication status monitoring unit 110 are not provided.

  Further, the mode transition unit 111 according to the second embodiment does not perform the operation mode transition determination process of the terminal, and switches the operation mode according to the operation mode notification received from the manager terminal 2.

  FIG. 20 is a diagram illustrating a configuration example of the manager terminal 2. The difference from FIG. 3 of the first embodiment is that the mode transition unit 111, the emergency contact communication unit 112, and the emergency information distribution unit 213 are not provided, and the mode determination unit 214 is provided.

  Based on the emergency information managed by the emergency information receiving unit 109 and the communication status managed by the communication status monitoring unit 110, the mode determination unit 214 performs a process for determining the operation mode of the learner's terminal 1, and the communication unit 106 In addition, the determined operation mode is notified to the learner's terminal 1.

  FIG. 21 is a flowchart showing an example of overall processing in the learner's terminal 1 and the administrator's terminal 2.

  First, in the manager terminal 2, when the communication unit 106 detects communication from another device, the control unit 105 receives the detected content as an event (step 6001). Next, the control unit 105 determines the type of the accepted event (step 6002).

  When the event type determined in step 6002 is “reception of emergency information”, the control unit 105 causes the emergency information reception unit 109 to save the emergency information received by the communication unit 106 in the storage unit 104 (step 6003). When the event type determined in step 6002 is “reception of communication status”, the control unit 105 causes the communication status monitoring unit 110 to save the communication status notified from the communication unit 106 in the storage unit 104 (step 6004). .

  After step 6003 or step 6004, the control unit 105 causes the mode determination unit 214 to execute mode determination processing (step 6005).

  The mode determination process in step 6005 in the manager terminal 2 is the same as the mode transition determination process described in step 1005 in FIG. 4, and in steps 2001 to 2004 in FIG. 5 and steps 3001 to 3004 in FIG. This is the same as the processing described.

  Next, in the manager terminal 2, the mode determination unit 214 causes the communication unit 106 to notify the learner terminal 1 of the determined operation mode (step 6006).

  Next, in the learner's terminal 1, when the communication unit 106 receives the operation mode notification from the manager's terminal 2 (step 6007), the control unit 105 sends the mode transition unit 111 a mode according to the received notification of the operation mode. The migration process is executed (step 6008).

  Next, the control unit 105 of the learner's terminal 1 causes the emergency contact communication unit 112 to execute emergency contact communication processing (step 6009). The emergency communication processing in step 6009 is the same as that in steps 4001 to 4007 in FIG. 9, and is processed according to the operation mode.

  As described above, according to the present embodiment, for example, both the learner's terminal 1 and the administrator's terminal 2 do not include the emergency information receiving unit 109 and the communication status monitoring unit 110, but one terminal Even when the emergency information receiving unit and the communication status monitoring unit are provided only in a certain manager's terminal 2, it is possible to appropriately deal with a failure when communication with the server becomes impossible.
