Abstract:The low-pressure pressurized wind tunnel is a kind of aerodynamically important test facility which is suitable for the development of science and technology in China's aviation industry. In order to ensure the high efficiency and reliable operation of the facility, the appropriate monitoring points are selected according to the fault mode and fault characteristics, and the real-time working status data are obtained, and then the data is based on the mechanical and electrical equipment, electrical measurement and control equipment and mechanical devices , make the best of state monitoring, fault diagnosis, fault prediction, to achieve pre-decision-making and targeted rapid maintenance. Based on the OSA-CBM + system, the wind tunnel health management system is used to realize the real-time judgment of the validity of the test data according to the running status of the equipment. The wind tunnel equipment is changed from post-service maintenance to maintenance. , Maintenance, management mode from decentralized management to intensive management changes; to achieve the equipment system fault diagnosis ,prediction and judgment from artificial intelligence to machine intelligence changes.
