Research Control System for 7500T 360 Degree Revolving Floating Crane

摘要

With the highly speed development of ocean oil, it was an important matter how to meet the requirement for the large floating ocean engineering ship. The floating crane is one of the most key equipment in the large floating ocean engineering ship. In this paper, the large revolving floating crane was regarded as the study object, and the field-bus technology T-LINK and MICREX-SX series PLC was adopted to build control system for the large revolving floating crane. T-LINK, as a kind of the field-bus control system, was communication medium of master station (MICREX-SX series PLC) and slave stations (MICREX-SX series PLC & Inverter VG7S). The control programs such as Different control logic, interlock logic and electric protection had been worked out, which makes it possible to monitor and control the large floating crane effectively.
