Abstract: This paper describes the constitution of the control network of a 21 028 m³ trailing suction hopper dredger (TSHD) “Jun Yang 1”, and summarizes the advantages and characteristics of this system. It analyzes the issues in practical application and discusses the method to avoid the similar problems during the design of new systems based on the design of the distributed integrated control system. It also briefly summarizes the development of the industrial control system and network, as well as the general evolution of the control system. The deep understanding of the control system can provide reference for the distributed control system of the TSHD based on PLC plus SCADA in the future.

Key words: Control system of trailing suction hopper dredger, distributed control, fiber optic ring network, PLC control system
