Research on automatic positioning of hoisting crane for heavy parts at sea based on BIM and RFID technology

Abstract

Due to the constraints of crane positioning, its behavior accuracy is relatively low. Therefore, the research on automatic positioning of crane for offshore heavy parts based on BIM and RFID technology is proposed. This paper makes a comprehensive analysis of the positioning constraints of offshore heavy lifting cranes from three perspectives: environmental constraints, operational constraints and safety constraints, and determines the corresponding control elements. In the positioning process, BIM and RFID technology are introduced, and the actual running state data of the hoisting crane is collected with the help of RFID technology. Based on the analysis results of the positioning constraint control elements of the hoisting crane with heavy offshore parts, the identification tag of RFID technology is set up. BIM model is used to decompose the scope of construction area and hoisting tasks in the early stage of hoisting, which is coupled with the data acquisition results of RFID technology to realize the location of specific positions. In the test results, the positioning error of the offshore heavy lifting crane in the X direction is stable within 0.4m, and the positioning error of the offshore heavy lifting crane in the Y direction is stable within 0.3m, which has high accuracy.
