| 摘 要： | 讨论了电厂球磨机料位测量的常用方法(主要包括差压法、音频法、功率法、振动法、气动差压法、应变法、油压法、物位法、出力法等)和存在的问题.由于单一测量方法均存在缺点,现已开始采用多传感器变量信息融合的软测量技术.介绍了建立软测量模型的一般理论和方法,讨论了当前球磨机料位测量中多种软测量技术的应用情况.展望了球磨机料位测量技术的发展趋势.

| Abstract: | The frequently-applied methods for ball mill level measurement,including differential pressure method,audio frequency method,power method,bearing vibration method,etc.,are discussed,as well as existing problems.Since each of these methods has its disadvantages,the soft-sensing technique of multi-sensor variable information fusion has been used in signal measurement.The general theories and methods for building soft-sensing models are proposed,and applications of several soft-sensing techniques to ball mill level measurement are discussed.The development tendency of ball mill level measurement techniques is prospected. |

| Keywords: | ball mill material level measurement differential pressure measurement soft-sensing neural network |
