摘要
介绍了PIC单片机实现掘进工作面双局扇自动切换控制系统中的应用,通过PIC单片机控制矿井局部通风机实现自动控制。通过风速传感器,接受到平率信号,传输给PIC控制器,由控制器自动判断风的变化,由另外一台风机,补充风量,确保井下矿道有一个稳定风速。PIC在自动监控当中,随时可判断出接受的信号,信号源是否稳定,由此信号源触发PIC外围控制电路,以达到快速灵活地控制风机。
PIC MCU heading face automatic switching control of double fan system,PIC microeontroller by local fan and automatic control of mine are introduced. Through wind speed sensor, receive fiat rate signal,transmitted to PIC controller, the controller automatically determine changes in wind,to judge by addition of wind turbine,added airflow,to underground mine road,to ensure steady wind. PIC in automatic control of them, readily determine signal acceptance, the stability of original signal, this external control signal of original trigger circuit PIC, to achieve fast and flexible control of fan.
