摘要
以液压设备运行状态在线监测为目标,采用电信号李萨如图融合技术,在工控机虚拟仪器平台中开发了包含李萨如图、电参量和功率圆等监测内容的状态监测系统。在交流电动机拖动液压系统实验台上进行实验,结果表明:李萨如图面积、倾角等特征参量与电功率参量能够反映液压设备负载工况,功率圆与电功率参量能够反映设备的功率匹配状况。
In order to monitor the operation state of hydraulic equipment online,using the electric signal Lissajous figure fusion technology,in the virtual instrument platform,a state monitoring system was developed,which includes such monitoring contents as Lissajous figure,electrical parameters and power circle.Using the motor driving hydraulic system bed stand as the experimental object,the results show that Lissajous figure areas,angles and electric power parameters can reflect the hydraulic equipment load power line status,power circles and the electric power parameters can reflect the equipment loading condition,the power circle and the electric power parameter can reflect the power matching state of the equipment.
