摘　　要：为预测大型机组状态,建立了灰色预测模型.并研制了具有开放性和柔性的虚拟仪器平台下的预测系统,以适应不同用户和不同环境 该系统在LabVIEW平台下并结合VC++编程实现,在工业现场得到实际应用.在大型供水机组上应用结果表明:采用该技术可以预测机组趋势性故障日期、减少维修次数和维护费用.To predict the conditions of large rotating machinery, a gray prediction model was proposed, and an open and flexible prediction system based on virtual instrument (VI) was developed for easy adaptation to new users and application. This system was developed by using LabVIEW and VC++,and has been applied in industry. The results of practical verification on large pumps indicate that the technology presented is capable of predicting the date of a fault and reducing the times and cost of maintenance. 
