[0011] 2. Data storage and processing: Using big data storage and processing technology, large amounts of test data can be efficiently stored and analyzed to extract valuable information.

[0012] 3. Remote monitoring and diagnosis: Through the Internet of Things technology, remote monitoring and fault diagnosis of the electrical performance of the induction cooker can be achieved to improve maintenance efficiency.

[0013] 4. Intelligent analysis and prediction: With the help of machine learning and artificial intelligence technology, test data is intelligently analyzed to predict the performance trends and potential failures of the induction cooker.
