摘要
针对矿井通风系统具有大时滞、时变性、多耦合等特性,传统控制中被控量难以及时反映矿用通风机的实际运行状况,基于模糊PID控制设计了矿井局部智能通风系统,从控制模型、系统架构、功能实现等方面进行研究设计。借助各类传感设备实现对通风机运行参数和环境气氛的实施监测,通过调节风机风量控制环境中的瓦斯浓度,保障生产安全;基于以太网技术实现井下远程通信与数据传输;通过上位机监控系统实现对通风机的远程实时监控、智能风量调节以及井下远程通信等功能;最后通过实践验证了使用模糊PID控制通风机智能调速,可实现22.13%的节能效果。
In view of the characteristics of long time delay,time-varying and multi-coupling of the mine ventilation system,it was difficult to reflect the actual operation status of mine ventilators in time in traditional control,so the local intelligent ventilation system of mine was designed based on fuzzy PID control,and its control model,system architecture and function realization were studied and designed.In addition,with the help of various sensing equipment,the operation parameters and environmental atmosphere of the ventilator were monitored,and the gas concentration in the environment was controlled by adjusting the air volume of the ventilator to ensure the safety of production.Then,the underground remote communication and data transmission were realized based on Ethernet technology.The functions of remote real-time monitoring,intelligent air volume adjustment and underground remote communication of the ventilator were realized through the host computer monitoring system.Finally,it was verified by practice that using fuzzy PID control for the intelligent speed regulation of the ventilator could achieve an energy saving effect of 22.13%.
