Let it be done.

  FIG. 3 is a flowchart of the first process executed by the gateway device 10 according to the embodiment of the present invention. The first process is a process for updating the sensor selection information D5 and the server setting information D6.

  First, the gateway device 10 acquires version information D1 and server connection information D3 from the server device 30 at random time intervals (S10). For example, the gateway device 10 may acquire the version information D1 and the server connection information D3 from the server device 30 at a time interval randomly selected from 15 minutes to 30 minutes.

  When the sensor version information D1a is updated among the acquired version information D1 (S11: Yes), the gateway device 10 acquires the sensor ID information D2 from the server device 30 (S12). The acquired sensor ID information D2 is stored in the gateway storage unit 15. Thereafter, the gateway device 10 updates the sensor selection information D5 based on the sensor ID information D2 when the restarting unit 16 restarts at a predetermined time (S13).

  On the other hand, when the sensor version information D1a has not been updated (S11: No), the gateway device 10 does not perform special processing and ends the first processing.

  When the sensor version information D1a has been updated (S11: Yes) and it is determined that the sensor ID information is acquired by the second communication unit 12, the gateway device 10 determines whether or not the server connection information D3 has been updated. (S14). That is, the gateway device 10 determines whether to change the server setting information D6 based on the server connection information D3. When the server connection information D3 has been updated (S14: Yes), the gateway device 10 saves the current server setting information D6 stored in the gateway storage unit 15 in another storage area of the gateway storage unit 15 ( S15) When the restarting unit 16 is restarted at a predetermined time, the server setting information D6 is updated based on the server connection information D3 (S16). Thereafter, the gateway apparatus 10 may perform the second process indicated as “A” in FIG. The second process will be described in detail with reference to the following diagram.

There is no need to open it, and unauthorized login can be prevented. Further, since the gateway device 10 does not need to accept remote access in order to update the sensor selection information D5, it is necessary to set the IP address as a fixed address without losing safety even if the login ID and password are simply set. The IP address can be set by DHCP (Dynamic Host Configuration Protocol). Therefore, the correspondence relationship between the sensor 20 and the gateway device 10 can be updated while achieving both easy management and high safety.

  Further, the gateway device 10 acquires the server connection information D3 stored in the server device 30, and determines whether or not the server setting information D6 indicating the transmission destination of the sensing data needs to be changed, thereby changing the transmission destination of the sensing data.

If the saved server setting information D6 is not stored (S20: No), the second process ends. When the saved server setting information D6 is stored (S20: Yes), the gateway device 10 determines whether or not the script version information D1b included in the version information D1 acquired from the server device 30 has been updated. (S21). When the script version information D1b has been updated (S21: Yes), the determination unit 13 determines to accept remote access from the server device 30, and the gateway device 10 acquires the script file D4 from the server device 30 ( S22). Thereafter, the gateway device 10 executes the script file D4, and the second communication unit accepts remote access from the server device 30 using the second communication protocol only for a predetermined period (S23). After accepting the remote access, the gateway device 10 deletes the saved server setting information D6 from the gateway storage unit 15 (S24).

  On the other hand, when the script version information D1b has not been updated (S21: No), the determination unit 13 determines that remote access from the server device 30 is not accepted, and the gateway device 10 stores the saved server setting information D6. It deletes from the gateway memory | storage part 15 (S24). Thus, the second process ends.

  Based on the version information D1, the determination unit 13 of the gateway device 10 determines whether or not the restart unit 16 needs to be restarted depending on whether or not the version information D1 has been updated (S30). When the version information D1 has not been updated (S30: No), it is determined that the restarting unit 16 does not need to restart, and the third process ends. On the other hand, when the version information D1 has been updated (S30: Yes), it is determined that the restarting unit 16 needs to be restarted, and the restarting unit 16 restarts at a predetermined time (S31). . Here, the predetermined time may be set to an arbitrary time, for example, may be set to a time when the frequency of measurement by the sensor 20 is low. When the sensor 20 is for measuring the open / closed state of the door, the predetermined time may be set to midnight or the like where people do not go in and out.

  The updating unit 14 performs the update when the restarting unit 16 restarts. More specifically, when the restart is performed, the updating unit 14 updates the sensor selection information D5 based on the sensor ID information D2 (S32), and the server setting information D6 based on the server connection information D3.
