The process inside steelmaking is complex: including important processes such as converter steelmaking, refining, and continuous casting; it is connected to ironmaking and steel rolling outside. In the entire steelmaking production process, the overhead crane, as the main transportation equipment for logistics, plays a pivotal role. The position change and weight change of the goods hoisted by the overhead crane are closely related to the design and implementation of the process flow. In addition, the control systems of various existing production links are scattered and independent. Due to the limitations of technological development and the lack of awareness of managers, many upper computers on site are basically in an independent state, the data distribution is relatively messy, and no unified network has been formed. Data cannot be shared, resulting in steelmaking data collection and statistics are still basically in a semi-manual state, mainly relying on the manual entry of the recorders of each section on site into the form and then summarizing and reporting, which leads to incomplete scheduling management, unsmooth process control, low production and consumption level, and low efficiency of production cost management. This is the shortcoming of the existing technology.
