Summary: | The invention discloses a complex ventilation network resolving method and resolving device, and relates to the technical field of mine ventilation. According to the method, a node wind pressure equation set, an auxiliary equation of the node wind pressure equation set, a fan wind pressure characteristic function and the like are unified into a generalized matrix equation, and composition, independent variable and dependent variable vectors, a Jacobian matrix and the like of the equation are defined, so that a Newton method is directly used for solving, and the programming quantity is small; due to the fact that the number of equations and the number of independent variables are not limited by the method and only the number of the equations and the number of the independent variables are related, the fan wind pressure characteristic function is added, the method is used for solving, and wind network direct solving can be achieved when the working condition points of the fan are not fixed; the auxiliary equati |
