It is necessary to conduct follow-up analysis of the causes of equipment failures, which is an essential task for effective maintenance and repair operations in a smart factory. Its main content includes determining the mechanisms of equipment failures, identifying the impact of various factors on the evolution of equipment failures, and controlling the development process of equipment failures. Methods for detecting failure mechanisms are generally based on failure cases. After a failure is detected, various tests need to be performed one by one to pinpoint the root cause, which is also the most accurate method in practice. However, due to the heavy workload in a smart factory, the economic and time costs of exhaustive testing are high. If a set of possible failure causes can be provided to maintenance personnel, subsequent costs can be significantly reduced.

The Smart Maintenance System of Alps System Integration (Dalian) Co., Ltd. establishes a full-lifecycle online archive for every piece of equipment in the factory. Historical failure records and equipment status are clearly visible, forming an equipment "medical record card" that helps enterprises quickly identify the root cause of failures, greatly reducing costs, and boosting the construction of smart factories.
