Operation Monitoring and Fault Diagnosis System forCertain Type Transonic Wind Tunnel |
| |
Abstract: | In order to meet the test efficiency and safe and reliable operation requirements of a transonic wind tunnel,the operation monitoring and fault diagnosis technology of the wind tunnel was studied. The system hardware adoptshierarchical structure to collect operation state parameters, uses software system analysis to collect data, realizes onlinemonitoring, alarm and early warning, fault diagnosis functions, and analyses the key technology of alarm and early warningstrategy setting and fault diagnosis. The practical application results show that the system can operate for a long timereliably and effectively, and has certain practical reference value. |
