FIG. 3 is a sequence diagram showing a process of collecting data acquired by the external terminal 20 in the server 30 via the mobile device 10 in the data collection system 1 shown in FIG.

  As shown in FIG. 3, in response to a request from the management terminal T, the control unit 33 of the server 30 generates a connection request for requesting a connection with the external terminal 20 and identifies the server 30. Server identification information is acquired from the storage unit 32 (S11). After generating the connection request and acquiring the server identification information, the control unit 33 transmits the connection request and the server identification information to the second communication unit 12 of the mobile device 10 via the communication unit 31 (S12).

  The second communication unit 12 of the mobile device 10 outputs the received connection request and server identification information to the control unit 15. Then, upon receiving an input from the second communication unit 12, the transmission control unit 15A of the control unit 15 determines whether or not the input server identification information indicates a permitted server that is permitted to connect to the external terminal 20. Is determined (S13). Here, if the input server identification information indicates an authorized server that is permitted to connect to the external terminal 20, the processing is continued, and the transmission control unit 15A sends a connection request from the server 30 to the first communication. The first communication unit 11 is instructed to transmit to the communication unit 23 of the external terminal 20. Thereby, a connection request is notified from the mobile device 10 to the external terminal 20 (S14). On the other hand, when the input server identification information indicates a server that is not permitted to connect to the external terminal 20, the mobile device 10 ends the process.

  The communication unit 23 of the external terminal 20 outputs the connection request received from the first communication unit 11 to the control unit 24. And the control part 24 performs an interconnection process between the servers 30 in order to transmit the data stored in the data storage part 22 via the mobile device 10 (S15).

  After the interconnection is established by the interconnection process, the control unit 24 of the external terminal 20 receives the instruction transmitted from the server 30 and the acquired data stored in the data storage unit 22 (that is, the data acquisition unit 21). The data to be transmitted to the server 30 is generated using the data acquired by (S16). Then, the control unit 24 outputs the generated data to the communication unit 23, and transmits the data to the server 30 via the mobile device 10 (S17). The communication unit 31 of the server 30 outputs the received acquisition data to the storage unit 32, and the storage unit 32 stores the acquisition data and ends the process (S18).

  FIG. 4 is a sequence diagram showing a data collection method according to another embodiment of the present invention. The difference from the data collection method shown in FIG. 3 is that before the mobile device 10 receives a connection request for requesting a connection with the external terminal 20 from the server 30, the mobile device 10 receives the acquired data of the external terminal 20. It is stored in the storage unit 13.

  As shown in FIG. 4, the control unit 15 of the mobile device 10 receives the operation acquired by the data acquisition unit 21 of the external terminal 20 in response to the operation of the input unit 16 by the user or the activation of the data collection application. An acquisition data request for requesting data transmission is generated (S101). Then, the control unit 15 transmits an acquisition data request to the communication unit 23 of the external terminal 20 via the first communication unit 11 (S102). After receiving the acquisition data request, the communication unit 23 outputs it to the control unit 24. In response to the acquisition data request, the control unit 24 performs an interconnection process with the server 30 in order to transmit the acquisition data stored in the data storage unit 22 (S103).

  After the interconnection is established by the interconnection process, the control unit 24 of the external terminal 20 uses the acquired data stored in the data storage unit 22 (that is, the data acquired by the data acquisition unit 21). Data to be transmitted to 10 is generated (S104). And the control part 24 outputs the produced | generated data to the communication part 23, and transmits to the 1st communication part 11 of the mobile apparatus 10 (S105). The first communication unit 11 of the mobile device 10 outputs the received acquisition data to the storage unit 13, and the storage unit 13 stores the acquisition data (S106).

  As described above, after the storage unit 13 of the mobile device 10 stores the acquired data, the second communication unit 12 of the mobile device 10 receives a connection request for requesting a connection with the external terminal 20 from the server 30. Subsequently, the following processing is performed.

  Upon receiving an instruction or the like from the management terminal T, the control unit 33 of the server 30 generates a connection request for requesting a connection with the external terminal 20 and stores server identification information for identifying the server 30 in the storage unit 32. (S107). After generating the connection request and acquiring the server identification information, the control unit 33 transmits the connection request and the server identification information to the second communication unit 12 of the mobile device 10 via the communication unit 31 (S108).

  The second communication unit 12 of the mobile device 10 outputs the received connection request and server identification information to the control unit 15. Then, upon receiving an input from the second communication unit 12, the transmission control unit 15A of the control unit 15 determines whether or not the input server identification information indicates a permitted server that is permitted to connect to the external terminal 20. Is determined (S109). Here, when the input server identification information indicates a permitted server that is permitted to connect to the external terminal 20, the processing is continued, and the transmission control unit 15A transmits the acquired data of the external terminal 20 to the second communication. The storage unit 13 is instructed to output to the unit 12, and is transmitted from the second communication unit 12 to the communication unit 31 of the server 30 (S110). On the other hand, if the input server identification information does not indicate a permitted server, the process ends.

  The communication unit 31 of the server 30 outputs the received acquisition data to the storage unit 32, and the storage unit 32 stores the acquisition data and ends the process (S111).

  With such a configuration, after the external terminal 20 transmits data to the mobile device 10, the data acquired by the external terminal 20 can be deleted even if the transmitted data is automatically deleted. It can be transmitted to the server 30.

  Next, with reference to FIG. 5, in the mobile device 10 according to the present embodiment, processing for rewriting the permitted server list (permitted server information) and password stored in the storage unit 13 of the mobile device 10 will be described.

  FIG. 10 is a sequence diagram showing a process for rewriting the permitted server list and password in the mobile device 10. First, a process related to rewriting is started based on activation of an application having a function for collecting acquired data of the external terminal 20 or power-on of the mobile device 10, and the rewrite control unit 15B of the control unit 15 It is confirmed whether or not the external memory 50 is attached to the attachment unit 14 (S21). If the external memory is not attached, the process is terminated. When the external memory is mounted, the rewrite control unit 15B checks whether or not a new permitted server list is stored in the external memory 50 mounted on the external memory mounting unit 14 (S22). If the list is not stored, the process ends.

  When the new permitted server list is stored in the external memory 50, the rewrite control unit 15B checks whether or not the new permitted server list is described in a prescribed format (S23), and the new authorized server list is defined. If it is not a format (format), the process is terminated. When the new permitted server list is in a prescribed format, the rewrite control unit 15B determines whether or not the set password stored in the storage unit 13 matches the current password (first password) stored in the external memory 50. (S24), and if the set password and the current password do not match, the process ends.

  When the set password matches the current password, the rewrite control unit 15B rewrites the permitted server information so that the permitted server list stored in the storage unit 13 is rewritten to the permitted server list stored in the external memory 50. Instruct the unit 15C. In response to the instruction from the rewrite control unit 15B, the permitted server information rewriting unit 15C rewrites the permitted server list in the storage unit 13 with a new permitted server list stored in the external memory 50 (S25).

  After rewriting the permitted server list, the rewrite control unit 15B checks whether or not a new password (second password) is stored in the external memory 50 (S26), and stores the new password in the external memory 50. If not, the process ends. When the new password is stored in the external memory 50, the rewrite control unit 15B rewrites the setting password stored in the storage unit 13 with the new password stored in the external memory 50. To instruct. In response to the instruction from the rewrite control unit 15B, the password rewriting unit 15D rewrites the set password in the storage unit 13 with a new password stored in the external memory 50 (S27). Thereby, the new password becomes the set password in the mobile device 10 thereafter.

Therefore, even a user who is unfamiliar with the operation of the mobile device 10 can easily change the permission server information.

  In addition, when the set password set in advance matches the current password (first password) stored in the external memory 50, the mobile device 10 is based on the permission server information stored in the external memory 50. The transmission control unit 15A may be configured to control the first communication unit 11 and the second communication unit 12. With this configuration, only when the external memory 50 that stores the password that matches the set password of the mobile device 10 is attached to the mobile device 10, it is based on the permission server information stored in the external memory 50. The transmission control unit 15A transmits data. Accordingly, it is possible to improve security when performing control based on the permitted server information stored in the external memory 50.

  Further, when the password (first password) stored in the external memory 50 matches the set password of the mobile device 10, the mobile device 10 uses the new password (second password stored in the external memory 50). The password rewriting unit 15D may be further provided. With this configuration, the setting password is changed each time control based on the permission server information stored in the external memory 50 is performed, so that the security in rewriting the permission server can be further improved.

  Note that the data collection system 1 and the data collection method also have technical features corresponding to the above-described embodiment of the mobile device 10 and have the same operations and effects.

  In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  For example, in the above embodiment, when the external memory 50 is mounted on the external memory mounting unit 14 of the mobile device 10, the permitted server list stored in the storage unit 13 is rewritten. A configuration may be adopted in which the permitted server list stored in the external memory 50 is directly read without rewriting. Even in such a configuration, the transmission control unit 15 </ b> A is configured so that the first communication unit 11 and the second communication unit are based on the permission server information stored in the external memory 50 mounted by the external memory mounting unit 14. 12 can be controlled.
