[0002]

2. Description of the Related Art Each module, which is a component as a functional unit constituting an electronic device such as an optical signal transmission device, is provided with software including a control program for controlling itself, and a failure or the like occurs. In some cases, the functions of the devices included in each module are maintained or improved, for example, when the module is replaced or a new module is added.

[0003] However, if each control program for controlling a replaced module or an added module is not of a standard corresponding to all control programs for controlling other modules, it is constituted by these modules. Conventionally, a module version management device in which a master module, which is one of the modules, has a function of managing version information of a control program installed in each module because the device does not perform regular processing. And so on.

FIG. 4 shows a module version management device 5.
FIG. 2 is a block diagram illustrating an electronic device on which the electronic device 0 is mounted. The module version management device 50 includes n (n is an arbitrary natural number) modules 6 as components as functional units.
In this embodiment, the transmission module is provided with the transmission module 60 provided with 1 to 6n and a master module, and the version management function is added to the master module of the transmission apparatus 60. Each of the modules 61 to 6n included in the transmission device 60 includes a control unit 61 that is controlled by itself.
a to 6na, and control sections 61a to 6na hold control programs for controlling the corresponding modules 61 to 6n, version information of the control programs, and the like.

[0005] The module version management device 50 includes:
A control unit 51 in which a control program for controlling the master module is stored, and version information of each module 61 to 6n adapted to the version of the control program of the control unit 51 are stored. A version management unit 52 is provided for performing comparison detection with version information of the control program to be controlled. In this case, the control unit 51 is configured to receive comparison result information from the version management unit 52 and output comparison detection result information to, for example, a personal computer 70 of an external information processing apparatus.

[0006] The module version management device 50 configured as described above, for example, when the power to the transmission device 60 is turned on and activated, the module 61 of the transmission device 60 is controlled by the version management unit 52 controlled by the control unit 51. ~
6n is read from each of the control units 61a to 6na, and the version information of each module 61 to 6n of a standard conforming to the version of the control program of the control unit 51 stored in advance is stored. Be compared. The version management unit 52 compares the version information, and if a match or mismatch of the version information is detected, the detection result information is output to the control unit 51.

[0007] Then, upon receiving the result of the version mismatch detection, the control unit 51 outputs mismatch information to the personal computer 70 of the external information processing apparatus, and the version of the module mounted on the display device of the personal computer 70 matches. Is displayed.

As described above, the personal computer 7
0, the version mismatch information is displayed on the display device, so that the user can recognize that the versions of the control program for controlling the module and the control program for controlling the master module are in a mismatched state. By recognizing the mismatch of the module, the appropriate version of the module management program is downloaded from the personal computer 70 to the module in the version mismatch state. Therefore, it is possible to make the device constituted by each module operate optimally.

[0009]

By the way, in the above-mentioned version management apparatus 50, only the mismatch of the versions of the control programs for controlling the respective modules is detected, and the subsequent appropriate control programs are in the version mismatch state. The process of adapting the version, such as downloading to a module, is left to the user, and there is a problem in that a cumbersome processing operation is forced and the process is inefficient.

In addition, in the process after the user recognizes the version mismatch, it is necessary to consider and execute the process content for adapting the version from the content of the version mismatch information. There is also a problem that operation may be performed.

[0011] In particular, when the process of adapting the version is complicated or difficult, the above-mentioned problem has been prominent.

The present invention solves the above-mentioned problem, and when a version mismatch of each module constituting the apparatus occurs, quickly and accurately adapts the version of the control program of each module to quickly bring it to an optimum state. The purpose is to:

[0013]

It has a function of outputting to a.

Next, a description will be given of a version management process of the module version management apparatus 10 of the present embodiment when a module is replaced or a module is added, with reference to FIG. The processing here is performed when a new module is mounted by, for example, replacing or adding a module of the transmission apparatus 20 in which the module version management apparatus 10 of the present embodiment is mounted, or after the module is mounted. When the power is turned on and the module is started, the control unit 11 recognizes, for example, that the module is newly mounted, and starts. In this example, in the following description, the module 21 is replaced with a new module 21.
N, and the new module 21N has a control unit 21aN that controls itself.

When the process is started, first, in step S201, a process of reading version information of a control program for controlling a newly mounted module is performed.
In this example, the reading process is performed by the version management unit 12 under the control of the control unit 11. In this example,
By instructing the control unit 21aN of the module 21N in which the version management unit 12 is mounted to output the version information of the control program of the control unit 21aN, the control unit 21aN sends the version information to the version management unit 12. Module 2 implemented to output
The version information of the control program for controlling 1N is read.

When the version information of the control program of the mounted module is read in step S201, the version of the control program of the mounted module matches the version of the control program for controlling the master module in step S202. Determine if there is. This determination process is performed by the version management unit 12 based on the control of the control unit 11. In this example, the determination is performed based on whether or not the read version information of the control program for controlling the module 21N matches any of the version information held in the version management unit 12.

If it is determined in step S202 that the version of the control program of the mounted module is compatible with the version of the control program for controlling the master module, that is, in this example, the module 21N is controlled. When the version information of the control program matches any one of the version information of the control program that is compatible with the control program that controls the master module held in the version management unit 12, the module 21N is controlled by the current control program. Thus, the transmission device 20 can perform an appropriate process, and thus the process is terminated.

On the other hand, if it is determined in step S202 that the version of the control program of the mounted module is not compatible with the version of the control program for controlling the master module, that is, in this example, the module 21N is controlled. If the version information of the control program 21aN to be executed does not match any of the version information of the control program compatible with the control program controlling the master module held in the version management unit 12, a mismatch signal is sent to the external device in step S203. Is output. In this example, the control unit 11 obtains the detection information of the version management unit 12 that has detected the version mismatch, and outputs the version mismatch signal to the personal computer 30 of the external information processing apparatus. For example, Module 2
Version mismatch information indicating that the version of the control program 21aN that controls the 1N is not appropriate is displayed on the screen of the display device of the personal computer 30.

In step S203, when a version mismatch signal is output, in step S204, in this example, the user is made to determine whether or not to execute a transfer process of a control program for matching versions. This determination is made in this example by the personal computer 30.
It is performed by the user operating the operation keys of
When it is determined that the transfer process is to be performed, a transfer execution signal is output to the control unit 11. On the other hand, when it is determined that the transfer process is not to be performed, a transfer non-execution signal is output to the control unit 11. In this determination, if the user determines that the transfer process is not to be performed and the transfer non-execution signal is output, the process here ends under the control of the control unit 11 that receives the transfer non-execution signal.

If the user determines that the transfer processing of the control program is to be executed in step S204, the transfer processing of the control program for matching the versions is performed in step S205. In this example, the transfer processing is performed by the control program management unit 13 based on the control of the control unit 11 that has received the transfer execution signal from the personal computer 30. Here, the module 21 having the version mismatch stored in the control program management unit 13 is stored.
For example, the control program CP1 corresponding to N is transferred and output to the module 21N in a compressed state.

When the transfer processing of the control program is performed in step S205, the control program of the mounted module is changed in step S206. This change processing is performed by the mounted module. In this example, the module 21N decompresses the compressed data of the control program CP1 transcribed from the control program management unit 13 and replaces the compressed data with the existing control program. The control program to be executed is changed to the control program CP1. When this control program change process ends, the process here ends.

Next, a version management process of the module version management device 10 of the present embodiment in the case where the control program of the master module is changed by inputting data from an external device to upgrade the entire transmission device 20 here will be described. 3 will be described. In this example, the processing here starts when the module version management apparatus 10 receives output data of the personal computer 30 including a control program for controlling all modules including the master module, for example.

When the module version management apparatus 10 receives data including a control program for controlling all modules including the master module, for example, first, in step S301, the control program for controlling the master module is renewed. Perform processing to change to a program. In this example, the change processing is performed by the control unit 11 that has received the control program data for the master module from the personal computer 30. Is stored as a new control program.
In this case, in this example, the control unit 11 expands the received compressed control program data for the master module and changes the control program.

When the control program of the master module is changed in step S301, the appropriate control program in each of the modules 21 to 2n (including the control program of a module not currently mounted) is changed in step S302. Perform processing. This change process
In this example, the control program is executed by the control program management unit 13. The control program held by the control program management unit 13 is changed to a new control program corresponding to each of the modules 21 to 2n received from the personal computer 30, and stored. The control program is a control program such as each of the modules 21 to 2n that matches the control program of the master module changed in step S301. In this case, in this example, the compressed data received from the personal computer 30 is held as it is.

At step S302, each of the modules 21-
When the appropriate control program such as 2n is changed, a process of updating the version information of the control programs such as the modules 21 to 2n that match the control program of the master module is performed in step S303. This updating process is performed by the version management unit 12 in this example, and the managed version information is stored in the personal computer 30.
Is updated to the version information that exists in the output data of. Steps S301 to S303 described above are performed.
Are performed in parallel.

When the processing of steps S301 to S303 is completed, the update processing of the module version management device 10 is completed. In this example, substantially the same as the processing of FIG. 2 for continuously updating the control program of each module to an appropriate control program. Is performed.

That is, the module version management device 10
After the update process of the above, in step S304, a process of reading version information of a control program for controlling each of the modules 21 to 2n is performed. The reading process is performed by the version management unit 12 under the control of the control unit 11 in this example. In this example, the version management unit 12 determines that each of the modules 21 to 2
n, by instructing the control units 21a to 21na to output version information of the control program possessed by the respective control units 21a to 21na, the control units 21a to 21na output the version information to the version management unit 12. The version information of the control program included in each of the modules 21 to 2n is read.

At step S304, each module 21-
When the version information of the 2n control program is read, in step S305, it is determined whether the version of the control program of each of the modules 21 to 2n is compatible with the version of the new control program that controls the master module. Make a decision. This determination process is performed by the version management unit 12 based on the control of the control unit 11. In this example, the version information of the control program that controls the read modules 21 to 2n is stored in the version management unit 1.
The update is performed based on whether or not the version information matches any one of the version information of the control program that matches the control program that controls the master module that is updated and held.

If it is determined in step S305 that all versions of the control programs of the modules 21 to 2n are compatible with the version of the control program controlling the master module, that is, in this example,
If all of the version information of the control program that controls each of the modules 21 to 2n matches any of the version information of the control program that is stored in the version management unit 12 and that is compatible with the control program that controls the master module, Each module 2 in the control program
Since the transmission device 20 can perform an appropriate process by controlling 1 to 2n, the process is terminated here.

On the other hand, if it is determined in step S305 that any version of the control program of each of the modules 21 to 2n is not compatible with the version of the control program controlling the master module, that is, in this example, One of the version information of the control program for controlling each of the modules 21 to 2n is stored in the version management unit 12.
If it does not match any of the version information of the control program that matches the control program that controls the master module stored in the external device, a process of outputting a mismatch signal to an external device is performed in step S306. In this example, the control unit 11 obtains the detection information of the version management unit 12 that has detected the version mismatch, and outputs the version mismatch signal to the personal computer 30 of the external information processing apparatus. Then, for example, version mismatch information indicating that the version of the control program that controls one or more modules is not appropriate is displayed on the screen of the display device of the personal computer 30.

When the version mismatch signal is output in step S306, in this example, in step S307, the user is caused to determine whether or not to execute the transfer processing of the control program for matching the versions. This determination is made in this example by the personal computer 30.
It is performed by the user operating the operation keys of
When it is determined that the transfer process is to be performed, a transfer execution signal is output to the control unit 11. On the other hand, when it is determined that the transfer process is not to be performed, a transfer non-execution signal is output to the control unit 11. In this determination, if the user determines that the transfer process is not to be performed and the transfer non-execution signal is output, the process here ends under the control of the control unit 11 that receives the transfer non-execution signal.

If the user determines in step S307 that transfer processing of the control program is to be executed, transfer processing of the control program for matching versions is performed in step S308. In this example, the transfer processing is performed by the control program management unit 13 based on the control of the control unit 11 that has received the transfer execution signal from the personal computer 30. Here, version mismatch 1
Alternatively, a control program newly stored in the control program management unit 13 corresponding to two or more modules is copied and output to one or more modules in a compressed state.

After the transfer processing of the control program in step S308 is performed, in step S309, processing for changing the control program of one or more modules in which version mismatch has occurred is performed. This change processing is performed by the module having the version mismatch. In this example, the module having the mismatch expands the compressed data of the control program transcribed from the control program management unit 13 and exchanges it with the existing control program. Is stored as a control program to be controlled by itself. When this control program change process ends, the process here ends.

As described above, since the control program of each module is held, the control program version of the replaced module or the added module does not match the control program version of the master module. Therefore, even if a mismatch occurs, there is no need to newly import a control program from the outside, and an appropriate version can be efficiently obtained. Further, since the control program to be held is compressed data, it can be configured at low cost without requiring a large storage capacity.

Further, since the control program of each module is held as described above, the version mismatch of the control program of the module is detected, and an appropriate control program is transferred to the module in which the version mismatch occurs. Module version can be automatically adjusted to the correct version without any cumbersome processing, and versions can be quickly and accurately integrated to quickly optimize the equipment configured by each module. State.

Further, since the control program of each module is held as described above, when the control program of the master module is updated, the control program of each held module is updated, so that the version of the entire apparatus is updated. The version can be upgraded, and the version of the module can be managed based on the stored data after the version upgrade.

In addition, since the above-described inconsistency detection is output to an external device so that the user can make a decision before transferring to the transfer processing, the control program of the inconsistency-detected module may not be erased. If inconvenience occurs if the transfer process is immediately performed, the process can be stopped at the discretion of the user.

In the above-described embodiment, the user determines whether or not to execute the transfer after the mismatch is detected. However, the transfer process may be executed immediately after the mismatch is detected. With this configuration,
Further, a control program for quickly controlling the module can be made appropriate.

In the above-described embodiment, the module version management device is applied to the transmission device. However, it is needless to say that the module version management device can be applied to various electronic devices and devices including a plurality of modules. is there.

As described above, according to the present invention, version control means for controlling a plurality of modules, storing version information adapted to a control program of a master module of a plurality of control programs, and a plurality of control means A control program management means for storing the program; and a mismatch detection means for comparing the version of the control program for controlling the newly installed module with the version stored in the version management means to detect a mismatch. Even if the control program version of the replaced module or added module does not match the control program version of the master module, a new control program must be imported from the outside even if a version mismatch occurs. And the right version It is possible.

In the case where there is provided a transfer output means for transferring a control program stored in the control program management means and outputting the control program to a newly mounted module by detecting a mismatch by the mismatch detection means, the version of the control program of the module is provided. Since a mismatch can be detected and an appropriate control program can be transcribed for the module where the version mismatch has occurred, the version of the installed module can be automatically adjusted to the appropriate version without performing any troublesome processing. Versions can be quickly and accurately integrated.

Data updating means for changing the control program of the master module and updating the storage data of the version management means and the storage data of the control program management means is provided. When the versions of the plurality of control programs to be controlled are compared with the versions stored in the version management means to detect inconsistencies, respectively, when the control program of the master module is updated, the control program of each module to be held is updated. , The version of the entire apparatus can be upgraded, and thereafter, the version of the module can be managed based on the stored data after the version upgrade.

When the module for which the mismatch is detected by the mismatch detecting means is provided with a transfer output means for transferring and outputting the control program stored in the control program managing means, the version mismatch of the control program of the module is detected. Since the appropriate control program can be transferred to the module having the version mismatch, the version of the installed module can be automatically made appropriate without performing any troublesome processing.
It is possible to quickly and accurately upgrade the entire apparatus.

The inconsistency detecting means detects and outputs to the external device, and the transfer output means erases the control program of the module in which the inconsistency is detected when the processing is executed in accordance with an instruction from the external device. If the transfer process is immediately performed, such as when it is not desired, the process can be stopped at the discretion of the user.
