Description

Modeling evaluation method and system for operation of complex equipment
Technical Field
The invention belongs to the technical field of intelligent manufacturing, and particularly relates to a modeling evaluation method and system for complex equipment operation.
Background

The method comprises the steps of establishing an operation state evaluation model of the power equipment by adopting a clustering-based equipment operation state evaluation method in the technical field of power automation, completing the establishment of an analysis model of the power equipment by taking historical data of the power equipment as a basis, and evaluating quantitative analysis, demonstration and comparison of the operation state of the power automation equipment through the model so as to realize the operation state evaluation of the power automation equipment; a method and a system for evaluating the state of a marine engine are established based on digital twins in the field of ship manufacturing, a corresponding digital twins model is established according to the parameter transfer relationship among a working process model, a fault diagnosis model and a structural strength finite element model, the input of the digital twins model is an operation parameter and an environment parameter, the model finally outputs a corresponding evaluation parameter, and the operation state of the marine engine is finally determined. A digital twin-driven intelligent line control chassis system and a fault diagnosis method thereof are provided in the aspect of automobile manufacturing, a digital twin model system of a line control chassis device is established through a digital twin technology, a virtual model and a physical entity are enabled to run consistently based on data driving, and real-time data interaction and fault diagnosis of the line control chassis device and an analysis model are realized.
Intelligent manufacturing and digital twin are taken as important directions of transformation development of the current manufacturing industry, enterprises expect to solve the intelligent management problem in the actual production process through modeling and analyzing of workshops, production lines and equipment, and assist managers to make decisions through mass data modeling and analyzing results in the production process. In the digital twin system, real equipment is mapped to virtual modeling for real-time driving based on data driving, and real-time interaction of data is realized. However, when model analysis is performed on equipment, a large amount of invalid data is often generated during initial construction, which causes extremely low accuracy of an actual application model trained by the model and also fails to accurately evaluate the real-time state of the equipment; secondly, at present, a fixed algorithm model is often established after feature mining for data analysis modeling of a device, or a model based on artificial experience knowledge, and the model established in the early production stage can influence the cost control of an enterprise along with the difficulty in accurately identifying the running state of the device after the later production task and mode adjustment of the enterprise; in addition, after the production mode of the equipment is adjusted, the fault type or the running state of the equipment is increased frequently, the traditional customized algorithm analysis model cannot be adjusted in a self-adaptive mode, and the risk of safe production of the equipment is increased.
Before actual production of equipment, modeling analysis is an important component for realizing digital twin of an enterprise intelligent production line and is a necessary link for providing a relatively ideal production scheme and increasing the core competitiveness of the enterprise. In recent years, industrial equipment such as industry, metallurgy and the like has a trend of large-scale and complex development, the complex equipment cannot be managed and monitored by establishing an accurate physical model completely by a traditional method, and in addition, a large amount of reaction operation mechanisms and real-time equipment state data are generated in the production process of the equipment. Based on factors such as production optimization and technology, for better utilization, an analysis method based on a statistical analysis model and qualitative experience knowledge is formed. However, these analysis methods have the following problems: 1) data characteristics of external factors are not combined into the model, so that the generalization of the model is low; 2) a large amount of historical data is needed for establishing an analysis model, and the requirement of the data size of model training cannot be met before equipment is produced and operated, so that the accuracy rate of the model is low; 3) the used algorithm model is fixed, and the situation that the device is not suitable for actual production exists after the device is operated on line.
