Abstract

The invention discloses a method for restoring a behavior model of an industrial software system based on data, belonging to the field of industrial software, comprising the steps of: obtaining operation feedback data; analyzing and classifying the data, extracting and constructing a relevant upper-level system model; verifying and generating a system model Whether it is accurate; summarize the corresponding original data that constitute the system modules, and generate the output of the system; verify whether there are related systems; integrate the existing subsystem models to generate the overall system model. Based on the feedback data of the existing industrial control software, the present invention can quickly, accurately and completely construct the industrial system software model; reduce the state space of the finite state machine model of the overall software system, simplify the process of data reverse construction of the system finite state machine; strong versatility , can be widely used in industrial system modeling, combined with basic unit code-driven function block packaging technology, can be quickly converted into industrial system control code.

Description

technical field [0001] The invention relates to the field of industrial software, in particular to a data-based method for restoring a behavior model of an industrial software system. Background technique [0002] The existing industrial control system has a huge system, which is composed of a combination of multiple components and modules, and has a complex structure, especially the system of its software system is more complicated. In the absence of source code, the original system cannot be improved and upgraded, software modules cannot be reused, and system maintenance is difficult. Moreover, the construction of the existing industrial control system model usually requires a preliminary analysis of the functional requirements, writes the required function documents, and continuously supplements and corrects the initial imperfect requirements documents during the system development process. The process that the system meets the requirements is a positive industrial contr...
