摘  要

 船舶航行在廣闊的大洋上，隨時都有可能發(fā)生各種突發(fā)事件，全船失電就是其中一種較常見的事故，如果不能及時處理，就極有可能引發(fā)更為嚴(yán)重的災(zāi)難。此刻，船舶應(yīng)急發(fā)電機(jī)組就及時的自動啟動，對一些重要的航行，消防和照明設(shè)備提供應(yīng)急電源，以保證船舶能繼續(xù)安全航行直至主電源恢復(fù)供電。由此可見船舶應(yīng)急發(fā)電機(jī)組的及時自啟動，提供應(yīng)急電源對于船舶有著及其重要的意義。本文通過對應(yīng)急發(fā)電機(jī)組自啟動要求的分析，結(jié)合設(shè)備現(xiàn)狀，利用PLC（可編程控制器）來制作船舶應(yīng)急發(fā)電機(jī)組自動起動控制器。

              Abstract

 The ships sailing in the vast ocean, any kinds of unexpected events may happen. the entire ship loses the electricity is one kind of common incident.If not it can not be soloved in time,the more serious diseaster is on the way. At this moment, the emergency generator sets automatica start to support electricity to a number of important navigation, fire and emergency lighting in order to ensure the safety of navigation be continued until the restoration of main power supply. From this we can see the emergency generating sets is very important. Based on the emergency generating sets analysis the requirements of automatica start, combined with the status of equipment, system design requirements, the use of PLC (programmable logic controller) to the produc of the ship emergency generator set automatic start controller.
