Description

Technical Field

[0001] This invention relates to the field of data information processing technology, and in particular to an intelligent operation and maintenance method and system based on data assets. Background Technology

[0002] With the rapid development of information technology, especially the maturity of technologies such as the Internet of Things (IoT), big data, and cloud computing, intelligent operation and maintenance (O&M) has gradually become an important part of modern enterprise management. Implementing intelligent O&M enables enterprises to achieve efficient resource management and optimization decisions through real-time monitoring of equipment status and operational data. The widespread application of IoT sensors makes equipment data collection more convenient and efficient; and through big data analytics, enterprises can predict faults, reduce costs, and improve equipment utilization efficiency. Furthermore, combined with artificial intelligence (AI) technology, intelligent O&M supports deep learning and analysis of massive amounts of data, helping to form adaptive and intelligent O&M strategies. This trend has already achieved significant results in various fields (such as manufacturing, power, and transportation), driving the intelligent transformation of equipment management.

[0003] While existing technologies have made some progress in intelligent operation and maintenance (O&M), several significant shortcomings remain. One major issue is the stability and efficiency of data transmission. In practical applications, IoT sensors often face difficulties such as communication latency and data packet loss, directly impacting data real-time performance and integrity. Furthermore, existing data models struggle to dynamically adjust to real-time data streams, often employing static models that cannot adapt to rapidly changing operating conditions. Simultaneously, the lack of effective data quality monitoring methods leads to delayed identification and processing of abnormal data, affecting the accuracy of O&M decisions. Moreover, existing methods typically rely on a single algorithm for risk prediction, failing to fully leverage the advantages of multiple algorithms, resulting in poor prediction performance. Therefore, to address these shortcomings, this invention proposes an intelligent O&M method based on data assets. This method aims to comprehensively improve the intelligence level of O&M by building a distributed IoT sensor cluster, optimizing data transmission paths, and utilizing dynamically adjusted data models and multi-algorithm fusion risk prediction models.
