The Design And Research Of The Simulation System Of The Ventilation In The Underground Laneway

This dissertation is came form the object"digital mine"develop by academy of water and electricity simulation center of hust and PingDingShan Coal Co., which used in simulate the ventilated system in the Underground Laneway.This dissertation contents include:Mathematical model: in research of mathematical model, do some analyze and research in the mathematical model of diagonal edge's automatic identification.The database of ventilation network and system simulation: Create database of ventilation network, set system parameter of the database, link database and main system of simulation system by ADO (ActiveX Data Object), give the function which this database system need to realize.Calculate system: This system realizes this function, calculated the direction of air flow, the blast volume and the resistance of wind of the entire pipeline, determine the power dissipation of system, find out the diagonal edge in the system.Create the 2d 3d model of ventilation system: Ventilation simulation system can create the 2D 3D model of ventilation system and the characteristic graph of ventilation network. The 2D model label the direction of air flow, the blast volume and the resistance of wind, this system can display all the parameter of every pipeline. The 3D model designed by OpenGL, this 3D model offer the function circumrotating and roam. This system can also realize this function that draw characteristic graph of ventilation network automatically.
