矿井通风系统分级控制研究
|
摘要
针对现有矿井通风系统控制未从通风系统整体角度考虑的问题,基于矿井通风系统结构及风量分布特征,提出了一种矿井通风系统分级控制方法。首先,通过比较通风状况参数的实时采集值和安全设定值,得出各用风地点通风状况参数偏差量;然后,利用自动纠偏控制器对偏差量进行在线整定和修改,并通过PID控制器获得通风状态调整参数;最后,智能控制模块根据通风状态调整参数,分别控制主要通风机供电模块的变频器、电动风门、压风管路末端的充气式气囊,实现全矿风量控制、采区风量控制、工作面风量控制3个层次的风量动态调节。该控制方法满足通风系统内风量循序、系统、连贯地调控要求。
In view of problem that present mine ventilation system control had not been considered from overall perspective of ventilation system,agrading control method of mine ventilation system was proposed based on structure of mine ventilation system and air volume distribution characteristics.Firstly,deviation value of ventilation condition parameters of each ventilation location is obtained by comparing real-time acquisition value and safety setting value of the ventilation condition parameters.Then the deviation value is online adjusted and modified by use of automatic correction controller,which is transmitted to PID controller to obtain ventilation condition adjustment parameters.At last,frequency converter of main fan power supply module,electric air door and air-filled air bag at the end of compressed air pipeline are respectively controlled by intelligent control module according to the ventilation condition adjustment parameters,so as to realize dynamic adjustment of air volume at three levels,which are air volume control of whole mine,air volume control of mining area and air volume control of working face.The control method meets requirements of sequential,systematic and coherent regulation of air volume in ventilation system.
