In order to solve the pain point problem of safety management in the construction period of a refining and chemical company, the platform construction integrates the company's information construction concepts of digitalization of the physical plant, informatisation of project management, and intelligent site management, and makes full use of the technologies of 5G, AI, and big data, and integrates the software and hardware facilities of the whole plant for safety management, so that ‘people, vehicles, and things’ of the construction site of ethylene and refining and expansion, which occupies an area of nearly 4,300 acres, are the objects of control through the application of IoT technology to achieve closed management of the plant. The construction site of ethylene and oil refinery expansion covers an area of nearly 4,300 acres, and takes ‘people, vehicles and things’ as the objects of control, and realizes the closed management of the plant through the application of IoT technology.

Through the combination of AI technology and mobile inspection, the existing monitoring video in the plant area is effectively used to structurally decompose the people, vehicles and objects in the video images, establish labels for the characteristics of people, vehicles and objects, and then classify and store them, and through the establishment of correlation with the business data, fast analysis and matching and retrieval of fuzzy characteristics are achieved. Intelligent analysis identifies safety hazard events such as failure to wear a helmet, smoking, making a phone call, gathering of people, vehicle lingering, smoke and flame detection, oil leakage, etc., to achieve timely prediction and alarm, and carry out whole-process control of violation issues.

Through the application of big data technology, the company's data from the construction period and the production period are fused to build a big data visualization platform, which continuously improves the level of enterprise safety management decision-making, thus effectively assisting the company's digital transformation work.
