步骤S102:计算离心机电流平均值,对离心机电流平均值大小划分区间,依据该区间存储步骤S101切割的输出管线压力的历史数据,该数据作为拟合用的基础数据。然后再次重复步骤S101,获得描述堵料情况类似步骤S101所有数据。
把离心机电流平均值划分为区间一[0,750),区间二[750,850),区间三[850,950),区间三[950,1050),区间四[1050,1150)。
把离心机电流基础数据作为yi代入如下公式:
其中:为离心机电流基础平均值,把该当前获得的输出管线压力历史数据存储为离心机电流平均值在区间三[950,1050)上的基础数据。
步骤二:利用拟合公式实时计算当前数据与基础数据的相似度,当相似度大于预设值时,执行阀门切换操作。具体过程如下:
步骤S201:通过PLC或DCS平台获取从当前时刻起向前10分钟的输送管线压力和离心机电流当前数据。

步骤S202:利用拟合公式,根据离心机电流平均值的不同值,分区间进行相似度的计算,然后计算控制器输出波形,周期=fit*10,持续时间60秒。
把离心机电流当前数据作为yi代入如下公式:
其中:为离心机电流当前平均值,可知离心机电流属于区间三,利用区间三上的输送管线压力基础数据进行拟合。
把输送管线压力当前数据作为yi代入如下公式:
把输送管线压力当前数据作为yi、输送管线压力基础数据作为和送管线压力当前数据均值/>代入如下公式:
最后计算出控制器输出波形的周期=fit*10=0.63*10=6.3秒。
步骤S203:根据方波序列的周期和持续时间,控制器产生方波序列,加湿开关阀根据该序列进行开关控制,振打器气源开关阀打开,振打器启动,一直持续到方波序列结束为止。
由步骤S202计算的方波序列的周期6.3秒,方波持续时间60秒,进行加湿器开关阀和振打器气源开关阀的控制,即在方波持续时间60秒内,振打器气源开关阀打开,加湿器开关阀打开6.3秒,关6.3秒,直到方波持续时间结束。
