中文摘要:

      在水泥生产过程中，球磨机的负荷检测和控制非常重要，球磨机的负荷决定了水泥生产的连续性和水泥质量的稳定性。〖KG-*4〗目前，没有直接检测球磨机负荷的方法，常用磨音、电机电流、提升机功率等间接方法获得，精确性和可靠性都较低，在生产实际中只能作为参考数据。提出一种多传感器数据融合的方法，采用自适应加权数据融合算法，选择磨音、磨机出口提升机功率、磨机电机电流、粗粉回粉流量4种传感器来综合检测磨机负荷，提高了球磨机负荷检测的准确性和可靠性。经过在水泥磨系统中的实际应用，验证了该方法的有效性。

英文摘要:

      In cement production process,the ball mill load detection and control is very important,ball load determines the continuity of cement production and cement quality and stability.Currently,there is no direct way to detect the ball mill load,often grinding sound,motor current,elevator and other indirect methods to obtain power,accuracy and reliability are lower,in the actual production only as reference data.A multi-sensor data fusion method is presented,using adaptive weighted fusion algorithm,selecting four kinds of sensors for collecting the grinding sound,the export elevator mill power,mill motor current,meal back to the powder flow to detect integrated mill load,the accuracy and reliability of ball mill load test are improved.Finally,the practical application of cement mill system verifies the effectiveness of the method.
