DCS在船舶机舱监测报警中的运用

机舱监测报警是船舶自动化的一个重要组成部分。该文设计和研制了适合船用的ＤＣＳ监测报警系统。系统的第一层是主站，功能是管理和显示；第二层为信息转发站，负责主站和监测报警站的通讯；第三层是监测报警站，直接面向船舶机舱的被测部位。本系统对机舱的各种物理信号，包括温度、液位、转速等巡回监测报警，具备丰富的显示和打印功能。系统中采用了各种抗干扰措施，按系统独立原则设计，确保了系统运行的可靠性。

Application of DCS in the Monitoring Alarm System of Marine Engine Room

The engine room monitoring alarm is an important part of marine automation. The DCS monitoring alarm system suitable for marine engine room is designed and researched in this paper. The first level of which is the main station for management and display, the second one is an information transfering station and the third one is a monitoring alarm system directly connecting to the measured parts of marine engine room. This system can detect various physical signals,including temperature, pressure, liquid level and rotation and possess rich display and print functions. Because of the independent design principle, the running of the system is reliable.
