液压支架工作状态模糊识别系统研究

针对目前综采工作面液压支架压力监测系统只能监测综采工作面压力,不能对液压支架工作状态进行识别的问题,设计了一种液压支架工作状态模糊识别系统。该系统可对现有的综采工作面液压支架压力监测系统监测到的压力数据进行模糊识别,根据模糊识别输出值即可判断液压支架的5种工作状态,即降架、移架、升架、增阻、卸压保持;当液压支架处于增阻工作状态且增阻时间过长时,该系统可及时通知液压支架操作工增大液压支架压力,辅助实现顶煤破碎。测试结果验证了该系统的可行性。

Research of Fuzzy Recognition System of Working State of Hydraulic Support

In view of problem that current pressure monitoring system of hydraulic support of fully mechanized coal face can only monitor pressure of fully mechanized coal face and cannot recognize working state of hydraulic support,a fuzzy recognition system of working state of hydraulic support was designed.The system makes fuzzy recognition for pressure data monitored by existed pressure monitoring system of hydraulic support of fully mechanized coal face to judge five working states of hydraulic support,namely reducing support,advancing support,lifting support,increasing resistance and pressure relief keeping according to output of fuzzy recognition.When hydraulic support is in working state of increasing resistance and time of increasing resistance is too long,the system can real-timely notify operator to increase pressure of hydraulic support and assist to realize top coal breaking.The test result validated feasibility of the system.
