Description

Automatic generation method of optical network relay system

The present invention relates to a method for automatically generating an optical network relay system, and more particularly, to a technology for automatically generating an optical network relay system diagram indicating a relay process using line information and device information (simple text information) of an optical network device.

In general, when transmitting information for communication, multiple subscriber information is simultaneously carried on an optical or general cable, and the subscriber line information can be reached through several paths in the middle from the transmitting relay station to the final receiving destination relay station. do.

At this time, the information transmitted in the form of a signal is relayed through multiplexing and demultiplexing for each relay station passing through until the signal arrives at its destination.

As such, a diagram showing information transmission systems and systems of a myriad of communication lines is an optical communication network relay diagram.

This optical network relay system is the information about the optical cable that enters the relay station, the optical station equipment that converts the signal from the optical cable into DS3 level signal, and the multiplexing device that converts DS3 level signal to DS1 level signal, and the line of each signal. This is a diagram showing the details, through which the operation status of the line can be found.

In generating a drawing used for such a purpose, conventionally, a person has manually created a drawing. Referring to the drawings, as shown in FIG. 1, the left and right sides are connected to the optical end station device as shown in FIG. Optical cable line history (Seoul-Daejeon 501) and DS3-class line history are shown.In the center of the figure, the DS2 line history connected to the multiplexing device as shown in section B and the DS1 line history branched therefrom are very complicated. A connection line is drawn like C to create a drawing between the DS3 class history of the single station device and the multiplexing device.

The optical network relay diagram created in this way is an essential drawing for constructing or dismantling a circuit. Since the drawing must be redrawn every time the circuit is changed, it is inconvenient to easily modify the drawing manually. I have a lot of difficulties in anger.

In the present invention, in order to solve the conventional problems as described above, even if the line is changed by using the character information consisting of the information of the optical communication device and the line history, it is possible to automatically generate the optical network relay diagram by modifying only the text information. The purpose of the present invention is to provide an automatic generation method.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the hardware environment applied to the present invention, the present invention has been implemented under INFORMAP III V3.6 as a VAX / VMS V5.4 and a graphic DBMS as an operating system.

In addition, the relay system automatic generation method implemented in the present invention can be implemented with only hardware such as a general computer, and is based on the apparatus as shown in FIG.

That is, the input device 10 for inputting the character data; An auxiliary memory device (11) for storing line history input through the input device (10); A main memory device 12 for storing the algorithm of the present invention; A central processing unit (13) for executing the algorithm of the present invention stored in the main memory device (12) and controlling each device; And an output device 14 for outputting a drawing result executed by the operation of the central processing unit 13, as long as the hardware can be executed.

Looking at the execution process of the present invention through the device as described above, if the line history required for generating the system diagram through the character input device 10 is inputted to the auxiliary storage device 11 the line history file for each of the relay station line history file When the optical communication network is generated in such a state, the circuit history stored in the auxiliary memory device 11 is read through the main memory device 12, and the central processing unit 13 performs calculations necessary for generating a drawing. After that, the drawings are stored in the auxiliary memory device 11.

Subsequently, a drawing is output through the output device 14 as necessary.

3 is a flowchart illustrating the automatic generation of the optical network relay system according to the present invention.

When the work for carrying out the present invention is started, the first step is to go through the process of setting the work environment (1), after receiving the name of the relay station to automatically generate the optical network network relay diagram for each relay station, and having the relay station name and the line name Put the relay table file in memory.

In this case, the relay table file is a file in which line history for all the relay stations for which the relay network is to be generated and line contents for the multiplexing device are stored (in FIG. 2, the content is stored in the auxiliary storage device 11). If you want to use this line history, read the line history of the corresponding relay station with the relay station name and line file name as above.

In the relay table file as described above, find the line history file of the corresponding relay station and copy it to the directory where the execution program is located to set the environment.

After the work environment setting process (1) is performed, the copied circuit description file (e.g., file contents shown in FIG. 4) is uploaded to a memory, and then optical and DS3 circuits belonging to the optical end station device are included in the circuit history.

Assign devices alternately to the device to be drawn on the left and right sides of the drawing in the order of height (in this order, ①, ②, ③, ④ in Figure 2). The width is set to the wider of the vertical widths of the optical station devices arranged on the left and right sides.

Then, the multiplexing apparatus to be drawn in the drawing is arranged in accordance with the vertical width of the drawing to be generated, and then the multiplexing apparatus is classified into left and right sides according to left and right positions on the drawing of the connected optical end station apparatus.

Subsequently, as shown in FIG. 6, the positions of the multiplexing devices to be drawn in the drawing are moved from the middle to the edges in the order in which they are to be connected to the optical end device (FIG. or ), And from top to bottom ( Below the line or Under (3) the connection lines between the optical station and the multiplexing device are not overlapped between lines.

After the generated macro file is executed in INFORMAP to generate the optical network relay system diagram (5), the work execution is finished.

In the relay diagram generated from the text data through the above process, the optical line station devices arranged on the left and right sides, the multiplexing device arranged in the middle part, and the connection line between the DS3 line details of the optical station device and the multiplexing device appear.

At this time, the size and complexity of the drawing increases and decreases according to the number of optical cables connected to the relay station.
