基于CAN总线的煤矿掘进通风机远程智能控制器设计

Design of Remote and Intelligent Controller of Mine Tunnelling Ventilator Based on CAN Bus

  • 摘要: 针对目前煤矿掘进巷道通风机普遍存在效率低、有害气体信号远程传输时抗干扰能力不足的问题,设计了一种基于CAN总线的煤矿掘进通风机远程智能多变量模糊控制器。该控制器可采集煤矿掘进工作面的有害气体浓度信号,应用多变量模糊控制方法智能控制变频器的频率,调节通风机的风量,降低有害气体浓度,减小通风机的电能消耗,解决了掘进巷道有害气体信号远程传输中的抗干扰问题。

     

    Abstract: In view of problems that current ventilator of mine tunnelling roadway has low efficiency and low anti-interference ability in remote transmission of harmful gases signals, a remote and intelligent fuzzy controller with multivariable of underground tunnelling ventilator based on CAN bus was designed. The controller can collect concentration signals of harmful gases in underground tunnelling working face, uses multivariate fuzzy control method to control frequency of frequency converter intelligently, so as to adjust air volume of ventilator, reduce concentration of harmful gases and power consumption of ventilator. The controller solves the problems of anti-interference of remote transmission of harmful gases signals in tunnelling roadway.
