Designing and Realizing of the Running State Monitoring and diagnosing System for Transonic and Supersonic Wind Tunnel

The automation and information level of a wind tunnel is the key factor affecting quality and efficiency of wind tunnel tests. A monitoring and diagnosis system of running status for the productive intermittent Tri-sonic wind tunnel has been developed in CARDC high speed institute. Combining distributed remote measurement and control technology and information system, it can monitor and record the key equipments state data of the crucial sections in the wind tunnel, meanwhile it can give an alarm in time when the state data is incorrect and giving suggestions for failure diagnosis, which enhanced security and dependability of the running system for wind tunnel testing, and improved automation and efficiency level of wind tunnel tests.
