JPS61248697A - Regenerating system for station data condition of electronic exchange - Google Patents

Abstract

PURPOSE:To simplify the maintenance of the regenerating system of station data condition by keeping a station data condition regenerating program independent from the address in the primary table of a station data. CONSTITUTION:A station data address list table 2 is prepared at a station data area (a station data part) in a switching on-line program other than several kinds of station data 1-n. It is assumed that the station data address list table 2 is a table which has a content of addresses of the primary table of each station and is the one that is not referred from the switching on-line program. The station data condition regenerating program recognizes memory addresses on the exchange of each station data by reading the table. When a document is regenerated from the station data that is the data of the switching on-line program, for the first, the station data address list table is read and from this, the address in the primary table of the station data is taken out. Based upon a taken out address, the document is regenerated following the station data from a master (the primary table) to a slave (a lower grade table).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for reproducing station data conditions of an electronic exchange in a general-purpose computer.

[Conventional technology]

The station data also needs to be significantly updated as the hardware of the electronic exchange is expanded and the exchange online program is upgraded.

In addition to this, station data is frequently updated, and accurate maintenance and management of the contents of station data is generally difficult. To update the station 1 data, as shown in Figure 3, the current station data is exchanged into the original form using the station data condition reproduction system, the necessary corrections are made to this original image, and the station data generation system generates new data from this original form. A method of converting to station data is adopted.

The structure of the station data is a tree structure (showing station data 1 to station data n) as shown in FIG. That is, the data of each station has a tree structure from the most parent table called the primary table to the lower tables.

From the exchange online program, only the primary table, which is the parent of the tree structure of station data, is directly referenced.

In the figure, this reference state is indicated by an arrow 1. In this way, in the station data condition reproduction system, the original table is reproduced by tracing the lower tables from the primary table of multiple types of station data, so the memory address on the exchange of the primary table of each station data, which is the starting point for original document reproduction, is It was necessary to have the information within the program.

Characteristics of station data" 2. If changes are made to the exchange online program, the station data will also be affected, and the address of the primary table may be changed. In response to this,
It was necessary to modify the address of the station data primary table contained in the program.

[Problem that the invention seeks to solve]

In the conventional two-way station data condition reproduction system, the memory address information on the exchange for station data is included in the program, so it is necessary to recreate the program in response to changes in the address of the primary table of station data. There is a drawback that there is.

[Means for solving problems]

SUMMARY OF THE INVENTION The object of the present invention is to provide a station data condition reproduction system that does not have the drawbacks mentioned above.

The present invention provides a station data condition reproduction system for an electronic exchange that reproduces an original form from station data that is data of an online exchange program, in which each station data is stored in the station data area of the online exchange program in addition to a plurality of types of station data. Add a station data address list table whose contents are the memory addresses of exchange L in the primary table of , extract the address of the primary table of station data from this station data address list table, and perform the station data based on the retrieved address. It is characterized by tracing the lower tables from the primary table of data and reproducing the original slip.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows the structure of station data in the present invention.
The station data area (station take section) has a station data address list table 2, which is a feature of the present invention, in addition to conventional plural types of station data 1 to station data n. This station data address list table 2 has the addresses of the primary table of each station's data as its contents, and is a table that is not referenced by the exchange online program.

The station data condition reproduction program can know the memory address of each station's data on the exchange by reading this table.

In this system, the original document is reproduced using the station data traversal function. This station data traversal function uses Pl and P2 shown in the following table as parameters, and its function is to directly extract the page containing this address from the composition file by the value of the address of the station data under the exchange given as the parameter Pl. The purpose is to retrieve the unit called and return the corresponding memory address on the general-purpose computer as the return value.

This station data traversal function can be calculated by giving the memory address of the station data on the exchange and the order of the station data.
Logically, pages containing the station data address for each order are stored in the general-purpose computer memory, and the memory address of the general-purpose computer is used as the return value. This function is used to reproduce the original document.

FIG. 2 shows the procedure for reproducing station data conditions in this embodiment. When the original document is to be reproduced from the station data which is the data of the exchange online program, first the station data address list table is read (step Sl). Next, the address of the primary table of station data is extracted from the station data address list table (step S2). Based on the retrieved address, the station data is traced from the parent (primary table) to the child (lower table) and the original slip is regenerated (step S3). In this case, the station data traversal function described above is utilized. If the original ticket has been reproduced from all the station data in the station data list table, the procedure is ended, and if it has not been reproduced, the process returns to step S1 (step 34).

According to the above-mentioned system, by reading the station data address list table, each station's data exchange
Since the memory address of - can be known, even if the address of the primary table of station data is changed, it will not affect the reproduction of the station data.

Therefore, there is no need to modify the program in response to a change in the address of the primary table of station data.

According to the present invention, by adding the station data at 1/list table as new station data, the exchange
Although an additional memory area of - is required, the required area is approximately 0.5 words and is not a burden.

〔Effect of the invention〕

As explained above, the present invention has the effect that maintenance of the station data condition reproduction system can be simplified by maintaining the uniqueness between the station data condition reproduction program and the address of the primary table of station data. .
