基于PLC的船舶主机遥控系统设计与实现

为了解决船舶主机无触点遥控系统出现的故障,分析了无触点主机遥控系统的特点,给出了其故障解决方案,设计并实现了基于S7-200PLC的主机遥控系统.S7-200主机遥控系统具备自动停车、自动启动(重启动、重复启动)、自动换向、自动制动、应急操纵、速度PID自整定调节、死区控制、速度和负荷限制、安全保护等功能,在工程船和远洋船上得到了成功应用.结果表明,应用S7-200PLC提高了主机遥控系统的可靠性、快速性和稳定性.

Design and implementation of marine main engine remote control system based on PLC

In order to solve the arisen trouble by the non contact remote control system of marine main engine,the paper analyzes the characteristics of the non contact remote control system,brings forward its trouble solving scheme,designs and implements a main engine remote control system based on S7-200 PLC. S7-200 main engine remote control system has the functions such as auto-stop,auto-starting(heavy starting,restarting),auto-reversing,auto-braking,emergency maneuvering,regulating speed of self-tuning PID,dead band control,speed limit and load limit,safety protection function and so on. The new system has been applied in the working ships and ocean going ships successfully. The results indicate that the application of S7-200 PLC improves the reliability,rapidness and stability of the main engine remote control system.
