Interactive switching system and processing method based on SDL graphics relationship

Abstract

The invention claims to protect an interactive exchange experiment system and processing method based on SDL graphic relationship recognition, which relates to communication and computer technology. The exchange experiment system uses the SDL graphic relationship recognition method to build an interactive exchange experiment system. The SDL graphic drawing module provides the user with the operation of drawing the SDL flow chart; the SDL graphic relationship identification module identifies the SDL state information and forms a standard SDL state transition. Table, saved into the configuration information base; the configuration operation module generates the program-controlled switch control strategy according to the SDL state transition table generated by the SDL graphic recognition module, automatically loads, and controls the operation of the corresponding modules of the switch, which effectively solves the problem of insufficient openness of the traditional experimental platform. The disadvantage of being difficult is that the PC can be used to reduce the cost of the experiment and improve the operability. The invention can be widely used in the experimental field of exchange principle in communication colleges and communication industries.

Description

technical field [0001] The present invention relates to communication and computer technology. Background technique [0002] The switch is the core of the communication system, and "Switching Principles" is therefore the backbone course of every communication major. Switching is highly complex, involves a lot of content, and is highly systematic. Experiments are very important for understanding the switching system. [0003] However, at present, the experimental methods are still in the demonstration of the process of making a phone call, man-machine command operation of the switchboard and parameter configuration. For the switch system, the whole structure of the switch, the coordination and cooperation between various parts, the sequence relationship of the signal flow, the operation status in different situations, etc. are not very clear, and the teaching purpose of the course has not been achieved in fact. [0004] The closest existing product with the present invention...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to design a program-controlled switchboard experimental system that is suitable for the developmental and comprehensive experimental requirements of the teaching of the exchange principle and is cheap, and solve the problems in the design of the existing exchange experiment system. , the experimental content and methods are single, and the experimenters cannot achieve the purpose of learning, we propose corresponding solutions
