Variable amplitude-based on-line early-warning method of process parameter and readable storage medium

The invention discloses a variable amplitude-based on-line early-warning method of a process parameter and a readable storage medium, and is used for solving the technical problem that abrupt change of a production parameter during the production process cannot be timely found out. The method comprises the steps of acquiring real-time data and historical data of the process parameter from a real-time database of a production system; calculating variable amplitude of an average value of the real-time data of the process parameter relative to the historical data; generating early-warning information of the process parameter according to preset early-warning configuration of the process parameter and the variable amplitude; and pushing the early-warning information according to a preset early-warning hierarchical push mechanism. According to the method, the real-time data is used as a basis, on-line continuous analysis and diagnose can be performed on various process parameters, a potential risk is found out, an
