Design Of Mine Fan Monitoring And Control System

Mine ventilation system is the key part of mine's safe production. Some factors including the safe of production, the prevention of disaster and the efficiency of economic are influenced by the condition of the mine ventilation system. The optimal selection of the wind volume in mine is an important way to save energy consumption by decreasing the unbalance between the supply and the need. It is very valuable to set up a digital mine ventilation monitoring control system for improving the work situation of mine ventilation system.Based on the actual situation and the function of mine ventilation control system, the design scheme of mine ventilation control system is proposed where includes three layouts:mine site monitoring layer, optical fiber communication network layer, ground control management layer, at the same time, the system architecture are described. According to the principle of Hydromechanics, two kinds of wind losses are simplified to compute the wind resistance of mine roadway conveniently, the model of mine ventilation network is build. Mine ventilation network model is computed by intend Newton arithmetic. The principle Schematic of key components including fans control diagram, Data Acquisition diagram, Ethernet diagram are present. The software including Driver Develop-ment, proper priority, communication between tasks,μC/OS-Ⅱand Net-work protocol Transplanting are established to meet the real time per-formance.By means of designed the mine ventilation network, the monitoring and control system is completed to achieve the purpose of controlling the ventilation system and adjusting the mine air volume ultimately, which gains economic benefits. Besides, theoretic basis are provided for the op-timization selection of schemes of mine ventilation system.
