Embodiment Construction

[0061] The invention will now be described in further detail with reference to the drawings.

[0062] The present invention proposes a method of adjusting the camera fault diagnosis, and the camera vibration failure intelligent diagnostic system is mainly used to predict the failure of the camera, providing a certain reaction time for the operator, and provides troubleshooting Recommended measures. The camera operation, the data, and the corresponding rotor data are used as input. Through historical statistical analysis, the calculation of the axial vibration reference value under each operating condition is calculated, and the real-time vibration signs is calculated by the dynamic difference value of the measurement point vibration reference value. The difference is greater than the reference value of the fault, and the positive and reverse bidirectional reasoning is performed until the cause of the fault, and outputs the fault type, the fault severity and the inspection guidance...

Abstract

The present invention provides a method for fault diagnosis of the camera, aiming at the problem that current equipment fault diagnosis mostly relies on front-line professionals to conduct detailed analysis and processing of on-site collection signals, and the real-time performance of fault discovery and processing in this mode will be limited. And considering the important role of the regulator in improving the DC transmission power and the voltage stability of the sending and receiving end grids, in order to ensure its safe and reliable operation, the present invention comprehensively uses forward and reverse mixed reasoning and expert on-site diagnosis rules (knowledge base ) and gray relational analysis method to calculate the degree of correlation and reliability of the input operation data and vibration data, which improves the real-time and accuracy of shaft vibration fault diagnosis of the condenser, and is of great significance to reduce the probability of equipment failure.

Description

Technical field [0001] The present invention belongs to the field of equipment fault diagnosis, and specifically, the present invention relates to a method of adjusting the camera fault diagnosis. Background technique [0002] The domestic adjustment camera fault diagnosis system is still in its infancy. The current monitoring technology is mainly the fault monitoring system of the transplant generator set. Tsuna University, Harbin Institute of Technology, Harbin Electric Meter, etc., jointly developed by the steam turbine generator operating conditions, the system of steam turbine generator system can fully monitor the mechanical vibration failure, vapor vibration failure, thermal factors caused by diagnostic units and regulation Control system failure. [0003] When the camera monitoring diagnostic platform, there are two systems with vibration monitoring protection and signal analysis fault diagnosis (TDM). The main role of the vibration monitoring protection system is only to...
