Early warning method and apparatus, network device, electric energy device, and medium

An early warning method, comprising:

• receiving, by communication circuitry of a device, early warning information from a network device when a historical production data feature of a component of the device matches an early warning indicator, the early warning indicator being determined by:
• performing correlation analysis on sample production data of a plurality of component samples and sample operation fault data of the plurality of component samples to obtain production fault correlation data, and
• determining, when the production fault correlation data indicates a correlation between the sample production data and the sample operation fault data, the early warning indicator based on the sample production data correlated with the sample operation fault data;
• and
• outputting, by processing circuitry of the device, the early warning information to a user of the device.

A device, comprising:

• processing circuitry configured to:
• obtain a historical production data feature of a component of a device during production of the component;
• determine whether the historical production data feature of the component matches an early warning indicator, the early warning indicator being determined by:
• performing correlation analysis on sample production data of a plurality of component samples and sample operation fault data of the plurality of component samples to obtain production fault correlation data, and
• determining, when the production fault correlation data indicates a correlation between the sample production data and the sample operation fault data, the early warning indicator based on the sample production data correlated with the sample operation fault data;
• and
• when the historical production data feature of the component matches the early warning indicator, generate early warning information for the component of the device.
