摘要
This paper sets up a mathematical model of switching network and switching function by utilizing graph theory to describe the logical function of different paths.The function varies with open and closed states of air doors in a complex mine air sub network, and the computer program for solving the switching function of complex networks are offered. It gives the method for discriminating a reversible branch in a complex network by means of the switching function, and the method of counter inverted logical control of airflow inversion by means of open and short circuit conversion of key branches. The research has solved the problem of the stablization of air flow for normal ventination and reversing ventination in a diagonal network.
