Description

  The present invention relates to a version management technique for managing a version of a program that causes a transmission device such as an optical transmission device to perform a predetermined operation, and in particular, has a plurality of packages and stores different programs depending on the type of package. The present invention relates to a version management technique for making a program stored in each package a latest version program in a simple transmission apparatus.

  Conventionally, when upgrading a transmission device such as an optical transmission device, the latest version of the program is downloaded from the operation system to the transmission device.

  FIG. 13 is a block diagram for explaining this type of conventional technology (for example, see Patent Document 1), in which an operation system 100 and a plurality of transmission apparatuses 200 are connected via a network.

  The operation system 100 includes a database 101, a management unit 102, and a transfer unit 103, and each transmission device 200 includes a CPU and a flash memory (not shown) in which a program is stored. In the database 101 in the operation system 100, a plurality of programs for each CPU of each transmission apparatus 200 and the latest version information of each program are registered.

  When the program stored in the database 101 is upgraded, the management unit 102 in the operation system 100 requests each transmission apparatus 200 for version information of the program being executed by each CPU. In response to this, each transmission device 200 transmits the program name and version information of the program executed by each CPU in the own device to the operation system 100.

  The management means 102 in the operation system 100 downloads a program to the transmission apparatus 200 based on the program name and version information sent from the transmission apparatus 200 and the latest version information of each program registered in the database 101. And the determined program is transferred to the transmission apparatus 200 using the transfer means 103. In the transmission apparatus 200, the latest version of the program sent from the operation system 100 is stored in the flash memory.

  Further, although it is not a technique for performing version management of a transmission apparatus, the following technique is conventionally known as a technique for performing terminal version management (see, for example, Patent Document 2). FIG. 14 is a block diagram for explaining a conventional technique described in Patent Document 2, in which a terminal 300 and a server 400 are connected via a network. The terminal 300 includes a version information request unit 301, a version management table 302, and a version comparison processing unit 303. The server 400 includes a version information transmission unit 401, a version management table 402, a program download unit 403, It has. Version information of each program being executed on the terminal 300 is registered in the version management table 302 in the terminal 300, and latest version information of each program is registered in the version management table 402 in the server 400.

  The version information request unit 301 in the terminal 300 requests version information from the server 400 when connected to the server 400. As a result, the version information transmission unit 401 in the server 400 transmits the version management table 402 to the terminal 300.

  The version comparison processing unit 303 in the terminal device 300 identifies the upgraded program by comparing the version management table 402 sent from the server 400 with the version management table 302 in the own device, and the program Is requested to the server 400. Accordingly, the server 400 downloads the requested program to the terminal 300, and the terminal 300 replaces the old version program with the new version program.

  According to the conventional technique described in Patent Document 1, the program of the transmission apparatus 200 can be upgraded to the latest version of the program, but there is a problem that the load on the operation system 100 increases. That is, in the conventional technique described in Patent Document 1, in the operation system 100, the version information of each program sent from each transmission apparatus 200, the latest version information of each program registered in the database 101, and Since the program to be downloaded is determined by comparing the two, the load on the operation system 100 increases.

  On the other hand, in the conventional technique described in Patent Document 2, a program to be downloaded by comparing the version management table 402 sent from the server 400 with the version management table 302 in the terminal 300 in the terminal 300. Therefore, the load on the server 400 can be reduced. However, since this conventional technique needs to provide the version management table 302 in the terminal 300, the following problems arise when applied to version management of the transmission apparatus.

  If they match (YES in step S95), the version comparison unit 212 transmits a version acquisition request to the next package (for example, the package 22-1) (step S92). On the other hand, if the two do not match (NO in step S95), a download request including package type information indicating the type of the package 22-1 is transmitted to the operation system 1 and further sent to the comparison result holding unit 214. A pair of the mounting position of the package 22-1 and its package type information is registered (steps S96 and S97), and then a version acquisition request is transmitted to the next package (for example, the package 22-2) (step S92). ). As a result, a download request is transmitted from the transmission device 2-1 to the operation system 1 as shown in FIG. When the version comparison processing unit 212 performs the above-described processing for all the packages in the transmission device 2-1 (NO in step S <b> 93), the version comparison processing unit 212 ends the processing.

  When the program download processing unit 12 in the operation system 1 receives the download request sent from the transmission device 2-1 via the transmission / reception unit 14, the program download processing unit 12 performs the processing shown in the flowchart of FIG. 8. The program download processing unit 12 reads the latest version of the program to be stored in the package of the type indicated by the package type information included in the download request from the program storage unit 152 and downloads it to the requesting transmission apparatus 2-1. (Step S81). At that time, the package type information included in the download request is also transmitted to the transmission apparatus 2-1. As a result, as shown in FIG. 11C, the program and package type information are sent from the operation system 1 to the transmission apparatus 2-1. Thereafter, the program download processing unit 12 waits for a download completion notification from the transmission device 2-1 (step S82).

  When the program storage processing unit 215 in the transmission apparatus 2-1 receives the program and package type information transmitted from the operation system 1 via the transmission / reception unit 211, the program storage processing unit 215 performs the processing illustrated in the flowchart of FIG. 10. First, the program storage processing unit 215 refers to the comparison result holding unit 214 to obtain a package mounting position as a program storage destination (step S101). More specifically, a pair including the package type information sent from the operation system 1 is searched from the pair of version type information and mounting position stored in the comparison result holding unit 214, and included in the pair. The mounting position of the package is the mounting position of the package that is the storage location of the program.

  Thereafter, with reference to the effective area display unit 244 on the package (for example, the package 22-1) for which the mounting position is obtained, which of the first and second areas 241 and 242 is currently being executed It is checked whether the program is stored, and the program downloaded from the operation system 1 is stored in the area on the opposite side (step S102). For example, if the effective area display unit 244 displays that the program currently being executed is stored in the first area 241, the program is stored in the second area 242. Thereafter, the program storage processing unit 215 transmits a download completion notification to the operation system 1 and waits for a switching command from the operation system 1 (steps S103 and S104). As a result, a download completion notification is transmitted from the transmission device 2-1 to the operation system 1 as shown in FIG.

  On the other hand, as shown in the flowchart of FIG. 8, the program download processing unit 12 waiting to receive the download completion notification is switched to the display unit 17 when the download completion notification is sent from the transmission device 2-1. A permission request screen is displayed, and switching permission is requested for the operation (step S83). FIG. 12 is a diagram showing an example of the switching permission request screen 121. The program name 122 of the program to be switched to the latest version, the ID 123 of the transmission apparatus storing the program, the permission button 124, and the prohibit button 125 is provided. The operator operates the permission button 124 when switching is permitted by looking at the switching permission request screen 121, and operates the prohibit button 125 when permission is not permitted.

  When the prohibit button 125 is operated (NO in step S84), the program download processing unit 12 ends the process. On the other hand, when the permission button 124 is operated, a switching command is transmitted to the transmission device 2-1 (YES in step S84, S85). The switch command includes package type information included in the download request. As a result, a switching command is sent from the operation system 1 to the transmission apparatus 2-1, as shown in FIG. Thereafter, the program download processing unit 12 waits for a notification of switching completion from the transmission device 2-1 (step S86).

  On the other hand, when the program storage processing unit 215 in the transmission apparatus 2-1 waiting for receiving the switching command receives the switching command via the transmission / reception unit 211 (YES in step S <b> 104 in FIG. 10), the comparison result holding unit 214. Referring to FIG. 5, the mounting position of the package that is the output destination of the switching instruction is obtained (step S105). That is, a pair including the same package type information as the package type information in the switching command is searched from the pair of package type and mounting position held in the comparison result holding unit 214, and included in the pair. Is the mounting position of the package that is the output destination of the switching instruction.

  Thereafter, the program storage processing unit 215 outputs a switching instruction to the package (for example, package 22-1) mounted at the mounting position obtained in step S105 (step S106), and enters a switching completion waiting state. (Step S107).

  When a switching instruction is input from the program storage processing unit 215, the switching processing unit 232 in the package 22-1 starts a program stored in an area different from the area displayed by the effective area display unit 244. Thereafter, the program storage processing unit 215 is notified of the completion of switching, and the contents of the effective area display unit 244 are changed to indicate another area. For example, when the effective area display unit 244 displays the first area 241, the program stored in the second area 242 is started, and then the effective area display unit 244 displays the second area 242. Change to what is shown.

  When the switching storage unit 232 is notified of the switching completion (YES in step S107), the program storage processing unit 215 in the switching completion waiting state transmits a switching completion notification to the operation system 1 (step S108). Thereby, as shown in FIG. 11 (f), a notification of completion of switching is transmitted from the transmission device 2-1 to the operation system 1.

  When the program download processing unit 12 in the state of waiting for the reception of the switch completion notification receives the switch completion notification from the transmission apparatus 2-1 (YES in step S <b> 86 in FIG. 8), the switch is completed on the display unit 17. Is displayed and the operator is informed (step S87). Note that if the switch completion notification is not received even after a predetermined time has elapsed since the switch completion notification is waited for (step S88 is YES), an error such as displaying that on the display unit 17 or the like. Processing is performed (step S89), and then the processing ends.
