煤矿通风安全预警系统研究与分析设计

Coal Mine Frequency Conversion Ventilation System Based on PLC

矿井通风系统在整个煤矿系统中起着非常重要的作用,主要的作用就是为矿井内部提供新鲜的空气和一个良好的气候条件,矿井内部随时都有可能出现瓦斯和有毒气体等,很容易出现安全事故,一个良好的矿井通风系统尤为重要,这就要求做好预警和报警处理,并且针对突发的情况做到快速有效地处理。在基于PLC控制技术的基础上,主要应用变频调节技术、现场总线控制技术和以太网通信技术完成了矿井主通风风机系统的设计与实现。能够对各种数据进行监测显示并且产生报警信息和报表文件,并且能够以通风负压为控制对象进行PID变频调节控制,改进和优化通风系统运行的稳定性和有效性,为矿井安全生产提供了良好的保障。

Based on PLC based control technology,the main application of frequency control technology,fieldbus control technology and Ethernet technology completed the design and implementation of the ventilation system of mine main fan. This paper designs the various data display and alarm monitoring information and report files,and to ventilation negative pressure as the control object of PID frequency control,stability of ventilation system operation and effective improvement and optimization,improve the good guarantee for coal mine safety production.
