Abstract

The invention discloses a nonlinear fault prediction method for electromechanical equipment. The nonlinear fault prediction method comprises the following steps: S100, model construction: constructinga BIM model of the electromechanical equipment of a building; s200, information detection: monitoring the important building electromechanical equipment in real time, and dynamically collecting monitoring data; s300, performing model bonding: constructing a building electromechanical equipment prediction model based on a bonding graph theory, and constructing a nonlinear machine equipment experiment platform to verify the constructed bonding graph model; s400, fault prediction; according to the method, the design is reasonable, the faults of the building electromechanical equipment can be accurately predicted, the sudden faults of the building electromechanical equipment can be reduced, the stable operation of the large-scale public building can be guaranteed, and the operation and maintenance cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of fault prediction, in particular to a nonlinear fault prediction method for electromechanical equipment. Background technique [0002] With the further improvement of the safety and reliability requirements of the electromechanical system, it is necessary to diagnose the system in time after the failure occurs, and to predict the failure after the system has a slight failure symptom. Fault prediction is to monitor and track the fault evolution process of the system, so as to predict the remaining working time of the faulty component. Effective prediction is beneficial to reduce the maintenance cost of electromechanical equipment and components, and is of great significance to prolong the service life of the system. [0003] However, the existing nonlinear fault prediction methods for electromechanical equipment lack the verification and verification of the prediction results in the actual application proc...
