Storage structure establishment and auto numbering realization of node inmine ventilation system

In order to solve a hard artificial establishment problem of the topological relationship in the mine ventilation system,establishment of ventilation system storage structure and automatic numbering realization of mode was studied,a programming technology was applied to realize the automatic establishment on the topological relationship of the main ventilation system.The results showed that the storage ventilation network of the data structure in the sequence list applied could speed up the data reading speed and meanwhile could reduce the requirements of the storage space.The establishment on the storage structure of the ventilation power could avoid a “false convergence” condition occurred and could optimize the characteristic curve of the ventilator.The storage structure of the ventilation facility established could optimize the treatment mode of the ventilation facility in the network resolution.In a large extent,the path search and the network resolution complicated could be reduced and thus the calculation speed and efficiency would be improved.The automatic numbering of the node could improve the efficiency and accuracy of the topological relationship established in the ventilation system and could provide a convenient and fast to the daily management and maintenance work of the ventilation system.The study applied to verify a ventilation system in a large mine could reduce 34.2% of the convergence time of the network resolution.
