摘要
采用S7-300 PLC控制通风机的变频调速,上位机利用组态王实现在线监控。系统实现主通风机的风压、风量的状态参数和电气参数的实时检测和通风量的动态调整,保证主通风机连续、可靠、安全的运行。
The paper proposes based on the S7-300 PLC control Mine main ventilator by frequency converter, upper monitor using KingView to achieve on-line monitoring.The dynamic adjustment of the parameters and electrical parameters of the real-time detection of the state of air volume and ventilation rate, ensure the main fan continuous, reliable and safe operation.
