This paper analyzes the current status and challenges of engineering digitalization and proposes a solution for building an artificial intelligence automated production line control platform for engineering “intelligent construction” (referred to as engineering production line control platform). It deeply explores the meaning and goals of the platform and innovatively puts forward the platform construction idea of “one database, one line, one factory”. This paper constructs a framework for the platform and verifies the feasibility of the overall solution through a case study of the digitalization of pumped storage power plants within a major construction group company. This paper provides valuable insights for promoting the construction, application, and promotion of integrated engineering digitalization.
