The intelligent control and real-time detection systems of mine ventilator based on ARM

Aimed at improving the reliability, real-time and energy-saving of mine ventilator air volume control system. This paper put forward a double fuzzy intelligent control system to self-adjusting ventilator speed based on the result of logical operations, which conclude gas and dust concentration. This system has ARMS3c2440 processor as the core of the monitoring and alarming subsystem, real-time display the gas and coal dust concentration and communication with PC by Ethernet. The simulation and experiment prove that the control system can regulate speed of ventilator automatically and continuously according to concentration change of gas and dust. It saves energy obviously and has higher real-time and reliability.
