At present, the perception, digitization, and networking of infrastructure within most chemical industrial parks are rela‐ tively low, and the overall level of safety production supervision informatization is not high. Managers have insufficient control over large enterprises, personnel, affairs, and materials. This article designs an intelligent chemical park management system based on the B/S architecture, which applies digital technology and networking methods to transform and upgrade traditional chemical parks. It establishes a 3D model of the park and enterprises, integrates data information collected by IoT devices, and builds a digital twin sys‐ tem for the park. It propose rules for the Ping An Index algorithm, monitor various scenario indicators of the enterprise, and conducts risk assessments on the data. It also proposes a closed-loop solution for production safety and abnormal indicators to achieve compre‐ hensive management of safety in chemical industrial parks.
