  There are two ways to edit the program file: when the center side edits the server program file, and when the local side edits the controller program file. For example, when editing a program file on a server on the center side, format extension of the program file occurs due to the addition of a new card reader type and the like. On the other hand, when the program file of the controller is edited on the local side, the number of program files increases due to the addition of an electric lock on the door.

  As described above, Patent Document 1 discloses selecting new access management setting information with reference to selection criteria information, but since the same selection criteria information exists, new access management settings information If you can not select or if an error occurs during data transmission via the network, how to deal with it is not clear.

  The present invention is intended to improve the problem of Patent Document 1 described above, and a method for coping with a case where the same reference information exists and new setting information can not be identified, or when an error occurs during data transmission via a network. It is an object of the present invention to provide a remote writing system provided with

The difference extraction unit 8 compares the center-side management flag 4B stored in the PFL storage unit 7 with the controller-side management flag 4C, and extracts program files having different contents of the management flag.

  Similarly, in the storage medium 206 of the controller 2, a program file storage unit 9 a (hereinafter, PF storage unit 9 a) storing program files α to 対 応 corresponding to the card reader to be managed and the door respectively; Program file storing controller-side program file list 5 (hereinafter referred to as controller-side PFL 5) including controller-side management flag 5C generated based on center-side management flag 5B sent from PC and program files α to PF of PF storage unit 9a It has a list storage unit 10 (hereinafter referred to as the PFL storage unit 10). The difference extraction unit 11 compares the center-side management flag 5B stored in the PFL storage unit 10 with the controller-side management flag 5C, and extracts program files having different contents of the management flag.

  Next, the structures of the center side PFL 4 and the controller side PFL 5 will be described in detail with reference to FIGS. 1B and 1C.

  As shown in FIG. 1B, the center side PFL 4 generates a center side management flag generated based on the program file name 4A corresponding to each of the card reader and the door to be managed and the program files α to PF of the PF storage unit 6a. 4B and the controller side management flag 4C transmitted from the controller 2. Here, each management flag has at least information on the file size of each program file and the editing date.

  Here, as a result of the center administrator editing the program file γ in the PF storage unit 6a using the PF editing unit 6b and updating the file size of the center side management flag 4B and the editing date, both of the program file γ The example which the content of the management flag differs is shown.

  Similarly, as shown in FIG. 1C, the controller-side program file list 5 includes program file names 5A corresponding to the card reader and the door to be managed, and the center-side management flag 5B transmitted from the server 1, The controller side management flag 5C is generated based on the program files α to の of the PF storage unit 9a. Here, each management flag has at least information on the file size of each program file and the editing date.

  Here, as a result of the local administrator editing the program file α of the PF storage unit 9a using the PF editing unit 9b and updating the file size of the controller side management flag 5C and the editing date, both of the program file α The example which the content of the management flag differs is shown.

  Next, processing until the program file edited on the server 1 side is reflected on the controller 2 will be described in detail with reference to FIG.

  First, when the center administrator edits the program file γ in the PF storage 6a using the PF editor 6b, the file size of the edited program file γ and the editing date are stored in the center side management flag 4B of the PFL storage 7 It is reflected (S20).

  Next, the server 1 receives the controller side management flag 5C from the controller 2 and overwrites it on the controller side management flag 4C of the PFL storage unit 7 (S21).

  Next, the difference extracting unit 8 of the server 1 compares the center-side management flag 4B with the controller-side management flag 4C, extracts program files having different file sizes, and confirms whether the editing dates match (S22) . In the example of FIG. 1B, although the file sizes of the program files α are equal, these files are not extracted, but the program files β and γ are extraction targets because the file sizes are different. Furthermore, it is confirmed that the edit date of the program file β matches, and the edit date of the program file γ does not match.

  As a result of comparison, when the file size is different and the program file having the same edit date is confirmed (Yes in S22), it means that the program file was edited on the same day by server 1 and controller 2, so the server The center administrator is warned that the update of overwriting the program file on the 1 side to the controller 2 requires attention (S28). In the example of FIG. 1B, attention is required to update the program file β whose file size is different and the edit date matches, so that the center administrator is alerted of its existence. In addition, various methods such as display on the management PC, e-mail notification to the center manager, printout of warning content, and the like can be selected for alerting. By performing such a warning, the administrator can check each of the program files of the server 1 and the controller 2 in detail, and edit the program file into an appropriate program file in which both are matched.

  On the other hand, if a program file having a different file size and a different editing date is confirmed from the comparison of both management flags (No in S22), those program files are extracted (S23). The side management flag 4B is transmitted (S24). In the example of FIG. 1B, the program file γ and the center side management flag 4B are transmitted.

  Next, the server 1 instructs the controller 2 to update the program file of the PF storage unit 9a and the controller-side management flag 5C of the PFL storage unit 10 to those transmitted in S24 (S25), and this instruction Controller 2 updates them accordingly.

  Thereafter, the server 1 instructs the controller 2 to transmit the updated controller side management flag 5C, and updates the controller side management flag 4C of the PFL storage unit 7 with the received controller side management flag 5C (S26). Then, the center-side management flag 4B of the PFL storage unit 7 is compared with the controller-side management flag 4C. If both match, it is determined that the update work has been completed normally, and the series of work is ended (Yes in S26). .

  On the other hand, when the center side management flag 4B of the PFL storage unit 7 and the controller side management flag 4C do not match (No in S26), this means that the transmission from the server 1 to the controller 2 has failed. Re-execute the process. By the procedure shown here, the update processing can be retried until the program file of the controller 2 and the controller side management flag 5C are successfully updated.

  Although FIG. 3 shows the process until the program file updated by the controller 2 is reflected on the server 1 side, this process is in contradiction with the process of FIG. 2, so the detailed description will be omitted. Do.

  Further, in the above embodiments, an example has been described in which the edit date of each program file is recorded in the management flag, but instead, the edit date and time may be recorded. In this case, it is possible to obtain an effect that the update of the program file can be managed more finely.

  As described above, according to the present embodiment, in the case where the program file relating to the same control target is stored in each of the server and the controller, the file size is different and the edit date is the same. By notifying the administrator of the fact, it is possible to avoid the loss of the edited contents due to the overwriting of the program file.

  Further, according to the present embodiment, by detecting a transmission failure of the program file generated between the server and the controller, the transmission of the program file and the management flag is repeated until the program file of the other party is updated. Program files can be updated.
