摘　　要：为模拟大功率海上风电机组增速箱轴承的实际工况,进行轴承可靠性分析,基于LabVIEW软件开发设计了一套轴承试验机测控系统。该系统以工控机为上位机,SIMATIC S7-1200系列PLC为下位机,通过Profinet总线建立数据交互实现对试验机驱动、液压加载及轴承润滑部分的精确控制。同时还可以根据预设的载荷谱自动运行,具有速度、振动、温度和压力等多参数采集显示、异常报警和自动保护功能。In order to simulate the actual working conditions of the speed-increasing box bearings of high-power offshore wind turbines and carry out bearing reliability analysis,a set of bearing testing machine measurement and control system was developed and designed based on LabVIEW software.The system uses the industrial computer as the upper computer,and the SIMATIC S7-1200 series PLC as the lower computer.The data interaction is established through the Profinet bus to realize the precise control of the driving,hydraulic loading,and bearing lubrication parts of the testing machine.At the same time,it can run automatically according to the preset load spectrum,with multi-parameter collection and display such as speed,vibration,temperature,pressure,abnormal alarm and automatic protection functions.
