Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data change history management method, and more particularly to a data change history management method using a remote centralized maintenance and operation device of an electronic exchange.

[Prior Art] Conventionally, in this type of data change history management method, all data change history data input by a plurality of maintenance personnel from all maintenance operation devices connected to the electronic exchange are converted into all input / output data of the electronic exchange. As a part of the data, the data is stored in the memory of the remote centralized maintenance and operation equipment, and the maintenance person of the electronic exchange searches and displays the data change history data from all the input / output data stored in the storage medium. Was recorded and managed.

[Problems to be Solved by the Invention] In this conventional data change history management system, after a command to be subjected to data change history management is input to the electronic exchange from the maintenance operation device or the remote centralized maintenance operation device of the electronic exchange, the electronic change is performed. If a problem occurred in the electronic exchange before the backup file for the software of the exchange was created, if the electronic exchange was restarted by reloading the backup file of the previously created software, That the command for data change history management entered after the backup file was created must be re-entered from the maintenance operation device or remote centralized maintenance operation device to the electronic exchange while viewing the managed recording paper. There was a point.

[Means for Solving the Problems] According to the present invention, a data change history in which a data change command to be managed is input from a remote centralized maintenance and operation device to an exchange and data change history management is performed based on the data change command In the management system, a first step of storing, in a memory of the remote centralized maintenance operation device, command name data of the exchange required for determining a data change history management target command of the exchange, and receiving data from the exchange. A second step of comparing the command name data stored in the memory with the command name data on the command image at the time of the command image, and storing the received command image in the memory if both match, When the received data is not a command image, the received data ends the command image. A third step of storing and managing the command image stored in the memory with additional information in the auxiliary storage medium for each of the exchanges which output the command image stored in the memory with additional information if the processing is a normal end; A fourth step of outputting and displaying the data change history management target command and the additional information stored in the auxiliary storage medium in response to a request from the maintenance person on the remote centralized maintenance operation device, and a request from the maintenance person. A fifth step of sequentially transmitting a data change history management target command designated by the maintenance person among the data change history management target commands stored in the auxiliary storage medium to a corresponding exchange; and storing the command in the auxiliary storage medium. The data change history management command specified by the maintenance person among the data change history management target commands and Data change history management method characterized in that it comprises a sixth step of deleting the target command and additional information from the auxiliary storage medium is obtained.

Example Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a remote centralized maintenance and operation apparatus showing one embodiment of the present invention, and FIG. 2 is a flowchart showing an input / output processing procedure of a central processing unit in FIG.

Referring to FIG. 1, a remote centralized maintenance and operation apparatus according to the present embodiment includes a central processing unit (CP) that controls all controls in the apparatus.
U) 2, a memory 1 for storing programs and various data processed by the CPU 2, a display device 4, a keyboard 5, an auxiliary storage medium 6, and a plurality of time-division exchanges 7 to 8 connected to the CPU 2 through an input / output interface 3. And

Next, an input / output processing procedure by the CPU 2 will be described with reference to FIG.

When the maintenance person inputs a request for storing command name data from the keyboard 5 (Y in step 21), the command name data is stored and held in the memory 1 and the auxiliary storage medium 6 (step 22). If the input data from the time-division exchanges 7,..., 8 is received (N in step 21), if the received data is not a request to store the command name data (N in step 21), the received data is It is checked whether or not the command image is a command image (step 24). If the data received in step 23 is a command image (Y in step 24), the command name data stored in the memory 1 and the command The name data is collated (step 25). If the two match (Y in step 25), the command image received in step 23 is stored in the memory 1 (step 26). As a result of step 24, when the data received in step 23 is not a command image, it is determined in step 26 whether or not the command image is an end message of the command image stored in the memory 1 (step 27). If the data is an end message of the command image stored in the memory 1 in step 26, it is determined whether or not the end message is a normal end (step 28). If Y in step 28, that is, if the end message is a normal end message, the command image stored in the memory 1 is added with additional information in step 26 and stored in the auxiliary storage medium 6 for each time-division exchange output (step 26). 29). Thereafter, the command image stored in the memory 1 is deleted (step 30). If N in step 28, that is, if the end message is an abnormal end message, the process proceeds to step 30. If N in step 27, that is, if the data received in step 23 is not an end message of collation OK, the input / output processing ends.

When the maintenance person inputs a control request of the data change history management command from the keyboard 5 (Y in step 31), each request from the maintenance person, such as screen output, sequential transmission, deletion of data from the auxiliary storage medium 6, control termination, etc. (Step 32). At this time, when the input from the maintenance person is determined to be a screen output request (step 33), the data change history management command stored in the auxiliary storage medium 6 for each time-division exchange is output to the screen and displayed on the display device 4. Display (Step 3
Four). When the display amount corresponding to the display capacity of the display device 4 is displayed, the process proceeds to step 39, and since it is not a control end request (N in step 39), the process returns to step 32. If the input from the maintenance person after step 32 is not a screen output request (N in step 33), but is determined to be a transmission request (Y in step 35), the auxiliary memory is stored in the time division switch designated by the maintenance person. Medium 6
The command image is extracted from the data change history management command designated by the maintenance person among the data change history management commands of the time-division exchange stored in the time division exchange and sequentially transmitted (step 36).

When the data change history management command specified by the maintenance person is transmitted, the process proceeds to step 39, and since it is not a control end request (N in step 39), the process returns to step 32. If the input from the maintenance person is not a screen output request (N in step 33) or a transmission request (N in step 35), and is determined to be a deletion request (step 37).
N), the data change history management command of the time division exchange designated by the maintenance person is deleted from the auxiliary storage medium 6 (step 38). When the data change history management command specified by the maintenance person is deleted, the process proceeds to step 39. Since the request is not a control end request (N in step 39), the process returns to step 32. Further, in the determination after step 32, the input from the maintenance person is not a screen output request (N in step 33), is not a transmission request (N in step 35), is not a control request (N in step 37), and When it is determined that the request is to end (Y in step 39), the control processing of the data change history management command is ended.

[Effects of the Invention] As described above, the present invention has a problem in the exchange before the software backup file is created after the data change history management target command is input to the exchange from the maintenance operation device or the remote centralized maintenance operation device. When the switch is restarted by reloading the backup file of the software created last time, the command for data change history management that needs to be re-input to the switch is provided in the remote centralized maintenance and operation equipment. Since the storage medium is stored and managed for each exchange, the maintainer can sequentially send the data change history management target command to the exchange just by specifying the data change history management target command that needs to be re-input.
This avoids a situation in which the maintenance person manually inputs the data change history management target command that needs to be re-input from the maintenance operation device or the remote centralized maintenance operation device. Therefore, after restarting the exchange where the trouble occurred,
This has the effect that it can be automatically restored to the state before the occurrence of the trouble.
