由于
PLC
除有继电器功能外，尚有多种其它功能，可以实现继电器无法
实现的控制功能，实现某种程度上的智能化，并有可能使机构简化
;
    (5)
可靠性高
; 
    (6)
具有扩展单元或扩展模块，当需要较多
I/0
时可以方便地扩展。
 
通过对各种控制系统的分析比较，我们决定采用
PLC
控制系统。

本章小结
 
   
本章主要讲述了舰船电站综合控制系统所要实现的功能和电站控制系统发
展的现状、趋势以及国内外对电站控制系统的分类
;
针对本电站控制系统设计所
采用的是
PLC
组成的集散控制系统
(DCS
)
，
讲述了它的特点和在工业领域中的应
用进行了总结，
同时对下位机所采用的可编程控制器的发展和趋势及与各种控制
系统的优越性进行了阐述。

章船舶电站控制系统工作原理及实现策略
 
2. 1
船舶电站控制系统的总体构成
 
   
随着船舶自动化程度的不断提高，
电站自动化也必然由局部的，
就地的控制
发展到综合的，
集中的控制，
并成为机舱自动化以至船舶自动化的重要组成部分。
 
电站的综合控制系统一般由电站自动控制系统，
自动监测报警系统和安全系统三
个互相独立又互相关联的系统组成。
