Functional block intelligent wiring method in modeling of control system

The invention discloses a functional block intelligent wiring method applied to the modeling of a complex industrial control system, which relates to intelligent wiring technology. In the invention, according to the characteristics of complex control relations, a plurality of functional blocks and a plurality of control loops, and the modeling requirements of high efficiency and high flexibility in the modeling process of the industrial control system, the intelligent wiring method is designed. In the method, through judgment on the number of break points of connecting lines, the trend selection of the connection lines, connection index determination, the resolution of coordinates of the break points of the connection lines and a transfer process of a state space in a wiring territory area, and by utilizing mapping and inverse mapping methods, the problems of the complex structure, much equipment, complex configuration relations and disordered configuration interface of an industrial control network are solved, the problem on interconnection among the different functional blocks is solved, and flexibility and applicability are relatively higher. The method has the advantages of high wiring speed, high connecting line quality, specifically remarkable superiority, certain promotion value, and high time complexity and space complexity when the functional blocks are in a certain scale.
