The old control system mainly using - and - now ca n ' t meet the high and complicated requirements of modern ship to control its boiler. it is imperative under the situation to use computer for ship control area. and the remarkable plc used currently by industry process control area is the most reliable, simple and convention way to realize computer control on board modern ship. the paper introduce simply the basic principle of plc and the characteristic of simens plc s5 - 115u and a typical boiler system of huge oil tank. on this base, the paper pay more attention to making control programme of s5 - 115u for huge marine fuel oil boiler. and pid control method is singly adopted for water level control and steam pressure control of the fuel oil boiler
以繼電? ?接觸器為主的老一代控制系統已不能滿足現代船舶對其鍋爐控制的越來越高、越來越復雜的要求，這一領域的計算機化已勢由必行，而應用在當前工業過程式控制制領域中引入注目的可編程序控制器（ plc ）又是使其計算機化的最簡便和可靠途徑。本文主要介紹可編程序控制器（ plc ）的基本工作原理、德國西門子可編程序控制器s5 - 115u和大型油輪鍋爐的典型系統，在此基礎上對用西門子s5 - 115u控制大型船舶燃油鍋爐進行了編程。
