Description

  The present invention relates to a transmission apparatus, and more particularly to a transmission apparatus that transmits a signal between communication line networks.

  The communication network is provided with a transmission device for multiplexing / demultiplexing or adding / dropping optical signals in a certain unit. Such a transmission apparatus includes a shelf having a backboard and a package (substrate) mounted on the backboard and exhibiting a predetermined function. Packages are divided according to function. For example, there are an optical package for transmitting and receiving optical signals, a SYNC package for outputting a clock for synchronizing signals, and a main package for controlling various packages to exhibit their functions. is there.

  Conventionally, in a transmission apparatus, a program for controlling each package is collectively stored in a nonvolatile storage device of a main package on which a CPU (Central Processing Unit) is mounted. Therefore, when a package revision occurs due to a hardware bug correction or a function addition, it is necessary to temporarily stop the processing of the entire apparatus and replace it with a program corresponding to the package revision.

  FIG. 17 is a block diagram of a conventional transmission apparatus. As shown in the figure, the transmission apparatus includes a main package 101, individual packages 102a, 102b,..., 102n that exhibit individual functions, and a back on which the main package 101 and the individual packages 102a, 102b,. A board 103 is provided. The main package 101 and the individual packages 102a, 102b,..., 102n can communicate with each other via the back board 103.

  The main package 101 includes a nonvolatile storage device 101a, a CPU 101b, and a volatile storage device 101c. The non-volatile storage device 101a stores a program 101aa for the individual packages 102a, 102b,..., 102n to perform individual functions. The program 101aa is expanded in the volatile storage device 101c and executed by the CPU 101b. Connected to the main package 101 is a maintenance terminal 104 equipped with a control / monitoring application for maintaining and operating the transmission apparatus.

  When the revision of the individual package occurs, the individual package is replaced and a program corresponding to the revision is transferred from the maintenance terminal 104 to the nonvolatile storage device 101a of the main package 101. Then, the CPU 101b is reset from the maintenance terminal 104, and the revised program is expanded and started up in the volatile storage device 101c.

In addition, when a non-volatile memory is installed in the electronic device, information such as the unit diagram number, function version number, and work version number is written in the memory, and the information in the memory is updated when the device or unit is revised. There is a management system for device diagram number and version number. According to this management method, the device diagram number and the version number can be easily changed and confirmed (see, for example, Patent Document 1).
Japanese Unexamined Patent Publication No. 55-92914 (first and second pages, FIG. 1)

  However, when a revision occurs in an individual package, since the program corresponding to the revision is transferred from the maintenance terminal to the main package, the work takes time in proportion to the number of transmission apparatuses that require the revision, and there are a plurality of program replacement work. Therefore, there is a problem that human error may occur during operation.

  In addition, it is necessary to reset the CPU to start the program after replacing the program. However, since the program for controlling each individual package is a group, even the individual packages that have not been revised are reset, and the entire transmission device There was a problem that the operation of must be paused.

The present invention has been made in view of these points, and an object of the present invention is to provide a transmission apparatus that simplifies revision work and suppresses the occurrence of human error during revision.
It is another object of the present invention to provide a transmission apparatus that eliminates the need for resetting individual packages that have not been revised, and that does not require the operation of the entire apparatus to be temporarily stopped at the time of revision.

  In the present invention, in order to solve the above problem, a plurality of individual packages 1 each having a program 1aa for exhibiting its own function in a transmission apparatus for transmitting signals between communication network as shown in FIG. And the storage device 2a, the transfer means 2b for transferring the program 1aa to the areas 2aa, 2ab, ..., 2an of the storage device 2a corresponding to each individual package 1, and the program 1aa transferred to the storage device 2a, There is provided a transmission device characterized by having a main package 2 having an execution means 2c that exhibits the function of the individual package 1.

  According to such a transmission apparatus, each individual package 1 is provided with a program 1aa for exhibiting its own function, and the transfer means 2b provides the areas 2aa, 2ab, ..., transfer program 1aa to 2an. Then, the program 1aa transferred to the areas 2aa, 2ab,..., 2an of the storage device 2a is executed by the execution means 2c, and the respective functions of the individual package 1 are exhibited.

  In the transmission apparatus of the present invention, the program is provided in the individual package and transferred to the storage device of the main package, so that the program can be revised together with the replacement of the individual package in which the revision has occurred, and the revision work is simplified, The occurrence of human error at the time of revision can be suppressed.

  In addition, since the program is transferred to the area of the storage device corresponding to each individual package, it is possible to reset only the program of the revised individual package and operate the individual package that has not been revised. The revision work can be performed.

  The principle of the transmission apparatus of the present invention will be described. FIG. 1 is a principle diagram illustrating the principle of the present invention. As shown in the figure, the transmission apparatus has a backboard 3, and a plurality of individual packages 1 and a main package 2 are mounted on the backboard 3. The individual package 1 and the main package 2 can communicate via the backboard 3.

  A storage device 1 a is mounted on each individual package 1. The storage device 1a stores a program 1aa for each individual package 1 to exhibit its function.

  The main package 2 has a storage device 2a, transfer means 2b, and execution means 2c. The transfer means 2b transfers the program 1aa stored in the storage device 1a of the individual package 1 to the areas 2aa, 2ab,..., 2an of the storage device 2a corresponding to each individual package 1.

The execution means 2c executes the program 1aa transferred to the storage device 2a and exhibits the function of the individual package 1.
The operation of the principle diagram will be described below. It is assumed that a revision has occurred in a part of the individual package 1. In this case, the program 1aa corresponding to the revision of the individual package 1 is stored in the storage device 1a of the individual package 1. The individual package 1 having undergone revision is mounted on the backboard 3.

  The transfer means 2b transfers the program 1aa of the individual package 1 in which the revision has occurred to the area of the storage device 2a corresponding to the individual package 1. The execution means 2c executes the program 1aa transferred to the storage device 2a and exhibits the function of the individual package 1 in which the revision has occurred. At this time, since the program 1aa is transferred for each of the areas 2aa, 2ab,..., 2an of the storage device 2a, it is not necessary to stop the execution of the program for which no other revision has occurred.

  As described above, since the program 1aa is stored in the storage device 1a of the individual package 1 and transferred to the storage device 2a of the main package 2, the revision of the program 1aa can be performed together with the replacement of the individual package 1 in which the revision has occurred. The revision work is simplified, and the occurrence of human error at the time of revision can be suppressed.

  Further, since the program 1aa of the individual package 1 is transferred to the areas 2aa, 2ab,..., 2an of the storage device 2a corresponding to each individual package 1, only the revised program 1aa of the individual package 1 is reset. Therefore, the revision work can be performed while operating the individual package 1 that has not been revised.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is a diagram illustrating a configuration example of an embodiment of a transmission apparatus according to the present invention. As shown in the figure, transmission devices 11a, 11b,..., 11n according to the present invention have communication network 12a, 12b,. The transmission devices 11a, 11b,..., 11n are connected to the optical cable 13 and can transmit and receive signals to and from each other. Each of the communication network 12a, 12b,..., 12n can communicate with each other by the transmission devices 11a, 11b,.

  A maintenance terminal 14 for maintaining and operating the transmission devices 11a, 11b,..., 11n is connected to the transmission device 11a via, for example, a LAN. The transmission apparatuses 11a, 11b,..., 11n are maintained and operated by an operation of the maintenance terminal 14 by an operator and an application for maintenance operation. In the figure, the maintenance terminal 14 is connected only to the transmission device 11a. However, the maintenance terminal 14 may be connected to each of the transmission devices 11a, 11b,.

  Next, the external appearance of the transmission device 11a will be described. FIG. 3 is a schematic external view of the transmission apparatus. As shown in the figure, the transmission device 11 a includes a shelf 21, a main package 22, and a plurality of individual packages 23 controlled by the main package 22. The individual packages 23 exhibit their functions under the control of the main package 22. FIG. 3 shows an optical package A and optical package B for transmitting / receiving optical signals to / from other transmission apparatuses, and a SYNC package C and SYNC package D for outputting a clock for synchronizing optical signals.

  On the back of the shelf 21, a back board 21 a for mounting the main package 22 and the individual package 23 is provided. The main package 22 and the individual package 23 are inserted from slots on the front side of the shelf 21 and mounted on the backboard 21a. The main package 22 and the individual package 23 can communicate via the backboard 21a.

  Next, the hardware configuration of the transmission apparatus 11a will be described. FIG. 4 is a hardware configuration diagram of the transmission apparatus. As shown in the figure, the main package 22 and the individual package 23 are mounted on the backboard 21a and can communicate with each other.

The main package 22 includes a nonvolatile storage device 22a, a CPU 22b, and a volatile storage device 22c.
The non-volatile storage device 22a stores a main processing program 22aa for performing a common process for all the individual packages 23. For example, a program for determining which of the individual packages 23 is mounted on the backboard 21a and a program for exchanging data with the individual package 23 are stored. The nonvolatile storage device 22a is, for example, a flash memory.

  The CPU 22b executes the main processing program 22aa and the package program 23aa transferred to the volatile storage device 22c, and controls the entire apparatus. The CPU 22b is connected to the maintenance terminal 14.

  When the individual package 23 is revised and mounted, the volatile storage device 22c is changed to the main processing program 22aa stored in the nonvolatile storage device 22a and the revised nonvolatile storage device of the individual package 23 by the CPU 22b. The stored package program is expanded. The CPU 22b executes the package program developed on the volatile storage device 22c. The volatile storage device 22c is, for example, a RAM (Random Access Memory).

  The individual package 23 has a nonvolatile storage device 23a. The non-volatile storage device 23a of each individual package 23 stores a package program 23aa for exhibiting the function of each individual package 23. For example, in the case of the optical package A described with reference to FIG. 3, a package program for optical communication with other transmission apparatuses is stored. In the case of the SYNC package C, a package program for outputting a clock for synchronizing optical signals is stored.

  Here, the program development of the volatile storage device 22c will be described. FIG. 5 is a diagram for explaining program development to the volatile storage device. As shown in the figure, the volatile storage device 22c is divided into regions 22ca, 22cb, and 22cc. In the area 22ca, the main processing program 22aa stored in the nonvolatile storage device 22a is expanded.

  The package program of the individual package 23 is expanded in the area 22cb. The package program of each individual package 23 is expanded to a corresponding address. Therefore, when a predetermined address is called, the package program of the individual package 23 corresponding to the address is executed.

  The latest version of the package program for each function type of the individual package 23 is held in the area 22cc. For example, in FIG. 3, two individual packages (optical packages A and B) for transmitting / receiving optical signals to / from other transmission apparatuses are mounted. Since the individual packages of the same function are executed by the same package program, only one latest version of the package program is held in the area 22cc.

  Next, the configuration of the package program 23aa will be described. FIG. 6 is a diagram for explaining the configuration of the package program. As shown in the figure, the package program 23aa is divided into an individual processing version number part 23ab, a function processing part 23ac, and a fixed data part 23ad. The individual processing version number section 23ab includes data indicating the version number of the package program 23aa. The function processing unit 23ac is configured with a program for causing the individual package 23 to exhibit a predetermined function. In the fixed data portion 23ad, data necessary for causing the individual package 23 to perform a predetermined function is configured.

  Hereinafter, the operation of FIG. 4 will be described. When the CPU 22b of the main package 22 rises from power-on or reset, the CPU 22b expands the main processing program 22aa stored in the nonvolatile storage device 22a to the volatile storage device 22c. Further, the CPU 22b determines the mounting state of each individual package 23, and expands the package program 23aa stored in the non-volatile storage device 23a of the mounted individual package 23 to the volatile storage device 22c of the main package 22. . As described with reference to FIG. 5, the CPU 22b develops the main processing program 22aa in the area 22ca and the package program 23aa in each address corresponding to each individual package 23 in the area 22cb. The latest version of the package program 23aa for each function of the individual package 23 is held in the area 22cc.

  The CPU 22b calls and executes the package program 23aa of each individual package 23 developed in the area 22cb of the volatile storage device 22c using the address. Thereby, the transmission apparatus 11a exhibits a predetermined function.

  When a revision occurs in the individual package 23, the revised package program is stored in the nonvolatile storage device 23a of the individual package 23. When the revised individual package 23 is mounted on the backboard 21a, the CPU 22b recognizes that the individual package 23 is mounted according to the main processing program 22aa. If the CPU 22b determines that the package is normally mounted, the revised package program stored in the nonvolatile storage device 23a of the revised individual package 23 is transferred to the volatile storage device 22c of the main package 22 via the backboard 21a. Forward. The CPU 22b executes the revised package program stored in the volatile storage device 22c and exhibits predetermined functions of the revised individual package 23.

  When revisions occur in a plurality of individual packages 23 having the same function, the revised package program is stored in one individual package 23. The CPU 22b holds only the revised package program among the individual packages 23 to be mounted in the area 22cc of the volatile storage device 22c. Then, the CPU 22b expands the revised package program to each address corresponding to the plurality of individual packages 23 in which the revision of the area 22cb of the volatile storage device 22c has occurred. That is, the latest version of the package program is stored in the area 22cc for each function type. In the area 22cb, the package program for the individual package 23 mounted is expanded.

  The CPU 22b compares the version number of the package program held in the area 22cc with the version number of the package program expanded in the area 22cb, and detects an old version of the package program expanded in the area 22cb. . The CPU 22b replaces the detected package program with the latest version of the package program held in the area 22cc. The CPU 22b also replaces the nonvolatile storage device 23a of the corresponding individual package 23 with the latest version of the package program. As a result, the latest package program is always executed. For example, even when an older individual package is additionally mounted, the latest package program is executed.

  Conventionally, when an individual package is revised, the individual package is replaced and the revised package program is stored in the maintenance terminal. Then, the version number of the package program in operation and the version number of the revised package program are checked and transferred to the main package of the transmission apparatus. Furthermore, the version number of the transferred package program was checked and reset. In this way, because multiple procedures were required, the same package program as the currently operating version is transferred, and it is assumed that it was transferred despite the transfer failure, and the subsequent processing is continued. Forgetting to reset to the main package, or when a revision occurs in a plurality of transmission apparatuses, there is a risk that a human error such as losing the revision work to the transmission apparatus targeted for revision may occur.

  In the present invention, for each individual package, a package program for performing the function of the individual package is stored, and the package program is expanded in the volatile storage device of the main package. As a result, the revision of the program is performed together with the exchange of the individual package in which the revision has occurred, so that the exchange work of the program from the maintenance terminal 14 and the resetting of the CPU 22b are unnecessary, and the revision work is simplified. Mistakes are eliminated.

  Also, since the package program is stored in the volatile storage area corresponding to each individual package, it is possible to reset only the package program of the revised individual package, and no other revisions are made. Revision work can be performed while operating individual packages.

  In addition, when there are multiple individual packages that exhibit the same function, transfer from one individual package that stores the revised program to all areas of the storage device corresponding to the individual package that exhibits the same function . Therefore, it is only necessary to store the revised package program in one of a plurality of individual packages having the same function, and the replacement work of the individual packages becomes easy. In particular, when a revision occurs only in the package program, it is only necessary to replace one individual package, and the work becomes easy.

  Next, the function of the transmission apparatus 11a will be described using a functional block diagram. FIG. 7 is a functional block diagram of the transmission apparatus. As shown in the figure, the transmission device 11a has the function of the main processing unit 30 by executing the main processing program 22aa shown in FIG. 4, and the package program 23aa of the individual package 23 developed in the volatile storage device 22c. The function of the individual processing unit 40 is provided by executing the above. The number of individual processing units 40 is equal to the number of individual packages 23 to be mounted, but only one is shown for the sake of simplicity.

The main processing unit 30 includes a package mounting change processing unit 31, an operation management unit 32, an individual process calling unit 33, and an individual process replacement unit 34.
The package mounting change processing unit 31 periodically monitors the mounting state of the individual package 23. When the individual package 23 is mounted, the package mounting change processing unit 31 acquires information on the version number of the package program 23aa, the slot number in which the individual package 23 is inserted, and the ID of the individual package 23. When the version number of the package program 23aa of the individual package 23 is the latest version, the package program 23aa is transferred to the area 22cc of the volatile storage device 22c, and further transferred to an address corresponding to the individual package 23 of the area 22cb. . When the package program 23aa is transferred from a plurality of individual packages 23 having the same function, the latest package program 23aa is transferred from one individual package 23.

  The package mounting change processing unit 31 requests the individual processing calling unit 33 to start the individual processing unit 40 when the individual package 23 is mounted, and requests a stop when the individual package 23 is not mounted. At this time, the package mounting change processing unit 31 hands over the information of the slot number into which the individual package 23 is inserted and the ID of the individual package 23 to the individual processing calling unit 33.

  The operation management unit 32 calls the individual process calling unit 33 and the individual process switching unit 34 in accordance with an instruction from the maintenance terminal 14 and transmits data from the maintenance terminal 14. In addition, an alarm / state change from the individual processing unit 40 is received via the individual processing calling unit 33 and notified to the maintenance terminal 14.

  The individual process calling unit 33 calls a package program developed in the volatile storage device 22c by a call from the package mounting change processing unit 31 and the operation management unit 32, and the individual processing unit 40 realized by the package program. Exchange data. The individual process calling unit 33 calls the individual processing unit 40 of each individual package 23 based on information such as the slot number in which the individual package 23 is mounted and the package ID. Each called individual processing unit 40 is processed in parallel and starts operation of the corresponding individual package 23. When the individual package 23 is not mounted (removed), the individual processing unit 40 corresponding to the individual package 23 stops its operation.

  When the package program developed in the area 22cb of the volatile storage device 22c is not the latest version, the individual process replacement unit 34 replaces the latest version with the package program stored in the area 22cc. Further, the nonvolatile storage device 23a of the individual package 23 storing the package program that is not the latest version is replaced with the latest version of the package program.

  The individual processing unit 40 includes a package data setting unit 41, a package control unit 42, an alarm / status data collection unit 43, an alarm / status monitoring unit 44, an alarm / status change notification unit 45, a fixed data storage area 46, and a variable data storage area. 47, and a data setting / collection target section 48.

  The package data setting unit 41 refers to a database (fixed data storage area 46) in which fixed setting values necessary for control are stored and a database (variable data storage area 47) in which data changed by control is stored. Then, setting data is created and data is set in the data setting / collection target unit 48. Data set in the data setting / collection target unit 48 is transmitted to the individual package 23, and the individual package 23 is controlled.

  The package control unit 42 performs control setting on the data setting / collection target unit 48 according to a control command from the maintenance terminal 14. Also, data update processing to the variable data storage area 47 is performed. Data set in the data setting / collection target unit 48 is transmitted to the individual package 23, and the individual package 23 is controlled.

  The alarm / state data collection unit 43 acquires an address for acquiring data from the individual package 23 from the fixed data storage area 46. The alarm / state data collection unit 43 transmits the acquired address to the data setting / collection target unit 48. The data setting / collection target unit 48 accesses the transmitted address, collects data from the individual package 23, and transmits it to the alarm / state data collection unit 43. The alarm / state data collection unit 43 passes the received data to the alarm / state monitoring unit 44. The alarm / state data collection unit 43 periodically collects data of the individual packages 23.

  The alarm / status monitoring unit 44 periodically creates a report on the current status of the individual package 23, the occurrence / recovery of the alarm, the change in the device status, etc. from the data collected by the alarm / status data collection unit 43.

The alarm / state change notification unit 45 converts the report sent from the alarm / state monitoring unit 44 into a format for notification of the maintenance terminal 14 and notifies the maintenance terminal 14 of the report.
Hereinafter, the operation of the transmission apparatus 11a of FIG. 7 will be described using a flowchart. FIG. 8 is a flowchart showing a processing flow of the package mounting change processing unit. The package mounting change processing unit 31 executes processing according to the following steps.

[Step S1] The package mounting change processing unit 31 is activated by a timer.
[Step S2] The package mounting change processing unit 31 sequentially detects whether or not the individual package 23 is mounted in the slot. When the package mounting change processing unit 31 detects whether or not the individual package 23 is mounted in all slots, the package mounting change processing unit 31 ends the processing. When the process ends, the package mounting change processing unit 31 enters a timeout waiting state, and is activated again with the occurrence of a timeout as a trigger.

[Step S3] The package mounting change processing unit 31 detects whether the individual package 23 is reset.
[Step S4] The package mounting change processing unit 31 determines whether the individual package 23 is mounted, whether there is a reset, information about whether the detected individual package 23 is an individual package to be operated (operated), and the slot in which the individual package 23 is inserted. Mounting state data including the ID number and the ID information of the individual package 23 is created. This process varies depending on the specifications of the transmission apparatus, and various mounting state data are created according to the specifications.

  [Step S5] The package mounting change processing unit 31 determines whether or not the individual package 23 has transitioned from a state in which the individual package 23 is not mounted. If it is determined that the individual package 23 is not mounted, the process proceeds to step S6. If it is determined that the individual package 23 has not transitioned from the state in which the individual package 23 is not mounted, the process proceeds to step S8.

  [Step S6] The package mounting change processing unit 31 determines the version number of the package program stored in the nonvolatile storage device 23a of the individual package 23 shown in FIG. 4 and the area of the volatile storage device 22c shown in FIG. The version number of the package program corresponding to the 22 cc individual package 23 is read, and it is determined whether or not the version number of the package program held in the individual package 23 is the latest. If it is determined that the version number is the latest, the process proceeds to step S7. If it is determined that the version number is not the latest, the process proceeds to step S8.

  [Step S7] The package mounting change processing unit 31 transfers the package program 23aa of the individual package 23 to the area 22cc of the volatile storage device 22c, and further transfers it to an address corresponding to the individual package 23 of the area 22cb. When the package program 23aa is transferred from a plurality of individual packages 23 having the same function, the latest package program 23aa is transferred from one individual package 23.

  [Step S8] The package mounting change processing unit 31 determines whether the mounting state of the individual package 23 has transitioned from the unmounted state to the mounted state, or whether a reset has occurred in the mounted state. If the individual package 23 has been mounted, or if a reset has occurred, the process proceeds to step S9. When the individual package 23 is not mounted or when the individual package 23 has not been reset, the process proceeds to step S10.

[Step S <b> 9] The package mounting change processing unit 31 transmits activation information including a parameter for activating the package data setting unit 41 to the individual process calling unit 33.
[Step S10] The package mounting change processing unit 31 determines whether or not the individual package 23 has transitioned from the mounted state to the unmounted state. When the state where the individual package 23 is mounted is changed to the state where it is not mounted, the process proceeds to step S11. When the individual package 23 has not been changed from the mounted state to the unmounted state, the process proceeds to step S2.

[Step S <b> 11] The package mounting change processing unit 31 transmits stop information including a parameter for stopping the individual processing unit 40 to the individual processing calling unit 33.
FIG. 9 is a flowchart showing a flow of processing of the operation management unit. The operation management unit 32 executes processing according to the following steps.

  [Step S21] The operation management unit 32 branches to a predetermined process in accordance with the requested process. When a command for maintenance operation of the transmission apparatus 11a is transmitted from the maintenance terminal 14, the process proceeds to step S22. If there is a request for replacement of the package program from the maintenance terminal 14, the process proceeds to step S23. When an alarm / state change notification is received from the individual processing unit 40, the process proceeds to step S24.

[Step S22] The operation management unit 32 passes a command for maintenance operation of the transmission apparatus 11a, which is transmitted from the maintenance terminal 14, to the individual process calling unit 33.
[Step S23] The operation management unit 32 calls the individual process replacement unit 34 in response to a request from the maintenance terminal 14.

[Step S24] The operation management unit 32 changes the alarm / state change notification from the individual processing unit 40 to a format for communication with the maintenance terminal 14 and transmits it to the maintenance terminal 14.
FIG. 10 is a flowchart showing a process flow of the individual process calling unit. The individual process calling unit 33 executes processes according to the following steps.

  [Step S31] The individual process calling unit 33 determines whether there is a storage area for storing the package program in the volatile storage device 22c from the slot number and the package ID information passed from the package mounting change processing unit 31. . If there is a storage area, the process proceeds to step S32. If there is no storage area, the process ends.

  [Step S32] The individual process calling unit 33 determines whether the information passed from the package mounting change processing unit 31 is start information or stop information. If it is activation information, the process proceeds to step S33. If it is stop information, the process proceeds to step S35.

[Step S <b> 33] The individual processing calling unit 33 transmits an activation command to the individual processing unit 40.
[Step S34] The individual process calling unit 33 receives from the individual processing unit 40 whether or not the activation process has been completed. When it is received that the startup process has been completed, the process ends. If it is received that the activation process has not been completed, the process proceeds to step S33.

[Step S <b> 35] The individual processing calling unit 33 transmits a stop command to the individual processing unit 40.
[Step S36] The individual process call unit 33 receives from the individual process unit 40 whether or not the stop process has been completed. When it is received that the stop process has been completed, the process ends. If it is received that the stop process has not been completed, the process proceeds to step S35.

FIG. 11 is a flowchart showing the flow of processing of the individual processing replacement unit. The individual process replacement unit 34 executes processes according to the following steps.
[Step S41] The individual process replacement unit 34 is activated by receiving, from the operation management unit 32 and the package mounting change processing unit 31, a replacement instruction including information on the individual package 23 for replacing the package program. The individual process replacement unit 34 receives whether or not the individual package 23 to be replaced is mounted. If the individual package 23 is mounted, the process proceeds to step S42. If the individual package 23 is not mounted, the process ends.

  [Step S42] The individual process replacement unit 34 determines whether or not there is an area for holding the package program in the nonvolatile storage device 23a. If it is determined that there is an area for holding the package program, the process proceeds to step S43. If it is determined that there is no area for holding the package program, the process ends.

  [Step S43] The individual process replacement unit 34 compares the package program developed in the area 22cb of the volatile storage device 22c with the version number of the latest version of the package program held in the area 22cc. If the version number of the package program developed in the area 22cb is not the latest version, the process proceeds to step S44. If it is the latest version, the process ends.

  [Step S44] The individual process replacement unit 34 replaces the package program in the area 22cb of the volatile storage device 22c with the latest version of the package program in the area 22cc. Further, the package program of the nonvolatile storage device 23a of the individual package 23 is replaced with the latest version.

  [Step S45] The individual process replacement unit 34 determines whether or not the individual package 23 to be replaced is in operation. This is because, for example, there are those in which the individual package 23 is mounted as a spare and is not operating. If it is determined that it is in operation, the process proceeds to step S46. If it is determined that it is not in operation, the process ends.

[Step S46] The individual process replacement unit 34 resets the replaced individual package 23 and ends the process.
FIG. 12 is a flowchart showing a process flow of the package data setting unit. The package data setting unit 41 executes processing according to the following steps.

[Step S51] The package data setting unit 41 acquires fixed data necessary for controlling the individual package 23 from the fixed data storage area 46.
[Step S52] The package data setting unit 41 creates a setting table from the acquired fixed data (data always exists in the fixed data storage area 46).

  [Step S <b> 53] The package data setting unit 41 determines whether or not variable data necessary for controlling the individual package 23 exists in the variable data storage area 47. This is because variable data required for controlling the individual package 23 may not exist in the variable data storage area 47. If the necessary variable data exists in the variable data storage area 47, the process proceeds to step S54. If the necessary variable data does not exist in the variable data storage area 47, the process proceeds to step S55.

[Step S54] The package data setting unit 41 adds variable data to the created setting table.
[Step S55] The package data setting unit 41 transmits the created setting table to the data setting / collection target unit 48. The data setting / collection target unit 48 transmits the data of the transmitted setting table to the individual package 23. The individual package 23 is controlled by the transmitted data.

FIG. 13 is a flowchart showing a process flow of the package control unit. The package control unit 42 executes processing according to the following steps.
[Step S61] The package control unit 42 branches to a predetermined process in accordance with a control command transmitted from the maintenance terminal 14 (via the operation management unit 32 and the individual process calling unit 33). In the case of a variable data rewrite command, the process proceeds to step S62. If it is not a variable data rewrite command, the process proceeds to step S64. A code is assigned to each control instruction, and the package control unit 42 switches processing according to the code.

[Step S62] The package control unit 42 rewrites the variable data storage area 47 with data transmitted from the maintenance terminal 14.
[Step S63] The package control unit 42 transmits a data setting request to the package data setting unit 41. The package data setting unit 41 creates a setting table based on the rewritten variable data in the variable data storage area 47 and transmits it to the data setting / collection target unit 48.

[Step S64] The package control unit 42 directly sets the data transmitted from the maintenance terminal 14 in the data setting / collection target unit 48.
FIG. 14 is a flowchart showing a processing flow of the alarm / state data collection unit. The alarm / state data collection unit 43 executes processing according to the following steps.

[Step S71] The alarm / state data collection unit 43 is activated by a timer.
[Step S <b> 72] The alarm / state data collection unit 43 acquires an address for acquiring the data of the individual package 23 from the fixed data storage area 46.

[Step S73] The alarm / state data collection unit 43 creates a data collection information table from the acquired addresses.
[Step S74] The alarm / state data collection unit 43 transmits the data collection information table to the data setting / collection target unit 48. The data setting / collection target unit 48 collects data from the individual package 23 based on the address of the data collection information table. The alarm / state data collection unit 43 acquires the data collected by the data setting / collection target unit 48.

  [Step S75] The alarm / state data collection unit 43 creates and stores a table of collected data (for example, stores it in the volatile storage device 22c) and transmits it to the alarm / state monitoring unit 44.

FIG. 15 is a flowchart showing the processing flow of the alarm / state monitoring unit. The alarm / state monitoring unit 44 executes processing according to the following steps.
[Step S81] The alarm / state monitoring unit 44 is activated by a timer.

[Step S82] The alarm / state monitoring unit 44 compares the latest information of the table created by the alarm / state data collection unit 43 with the information of the previous table held.
[Step S83] The alarm / state monitoring unit 44 proceeds to step S84 if there is a difference as a result of comparing the tables. If there is no difference, the process ends.

[Step S84] The alarm / status monitoring unit 44 creates a report of a fault / device status in which a difference has occurred (changed).
[Step S85] The alarm / state monitoring unit 44 transmits the created report to the alarm / state change notification unit 45.

  [Step S86] The alarm / state monitoring unit 44 updates the apparatus state and ends the process. When the processing is completed, the alarm / state monitoring unit 44 enters a timeout waiting state and is activated again with the occurrence of the timeout as a trigger.

FIG. 16 is a flowchart showing the processing flow of the alarm / state change notification unit. The alarm / state change notification unit 45 executes processing according to the following steps.
[Step S91] The alarm / state change notification unit 45 receives the failure / device state report created by the alarm / state monitoring unit 44.

[Step S92] The alarm / status change notification unit 45 converts the failure / device status report into a format that can be notified to the maintenance terminal 14, and transmits the report to the maintenance terminal 14.
In this way, the presence / absence of an individual package is detected and the latest package program is transferred, and if there is an individual package having the same function, the package program is transferred from one individual package to the storage device. Thus, the package program can be revised together with the replacement of the individual package in which the revision has occurred, the revision work can be simplified, and the occurrence of human error during the revision can be suppressed.

  In addition, since the package program is stored at the address of the volatile storage device corresponding to each individual package, it is possible to reset only the package program of the revised individual package, and no other revision is performed. Revision work can be performed while operating individual packages.

  Further, by replacing the package program to be executed with the latest version of the package program, for example, even when an older individual package is additionally mounted, the latest version of the package program is executed.
