Code correction method and device and intelligent analysis system

The invention provides a code correction method, a code correction device and an intelligent analysis system. The method comprises the following steps: analyzing a source code and converting the source code into a syntax tree; performing pre-analysis according to the code blacklist and the syntax tree to obtain a first analysis result; inputting the first analysis result, the syntax tree and the source code into a code correction model to obtain a first correction code under the condition that the first analysis result is that the vulnerability exists; under the condition that the first analysis result is that no vulnerability exists, control flow analysis is performed on the control flow to obtain a second analysis result, and data flow analysis is performed on the data flow to obtain a third analysis result; performing simulation analysis on the source code in a simulation environment to obtain a fourth analysis result; and inputting the second analysis result, the third analysis result, the fourth analysis
