| Title | Mobile Coalmine Methane Pumping-exhaust System Based on Online Interpolation Fuzzy Control |
| Abstract | The situation of coalmine safety in China remains serious. The chief of all disaster is the sudden gas outburst.Aiming at the problems and the potential safety hazards of the current gas pumping-exhaust system widespread used, sturdy the intelligent control of coalmine gas mobile pumping-exhaust system is researched and the current system is optimized. Especially the system researched places a branch of backflow and a valve, which can adjust the gas flow intelligently. The system can monitor and display the gas concentration, give an alarm when the gas concentration overrun, turn off the electricity and information network. Besides, the protection of the system while the water break is added. The system developed has no leakage, control effectively, run safely, and maintenance of the system is small. The system is an energy-efficient and cost-low system.The paper, based on the research of predecessor, study the problem in worksite deep going way, and then, bring forward the new arithmetic of online interpolation fuzzy control. This new arithmetic can make the control ruler much more smoothness, can make the controller much more smoothness exact, and improve the performance of control system greatly. We bring forward the control method of double-pump-operation, based on the condition of worksite, which accord with practicality further batter. In addition, we designed function of fault-self-diagnosis for worker overhaul conveniently.The entire intelligent control of the gas drainage is realized by gas density monitors union combined with fuzzy control arithmetic. It has solved the problem that the gas density often oversteps the regulate value in the present coal mine drainage system. It has raised the control accuracy security and reliability of the system. Therefore, the research on the project has good applying prospect. |
