基于PLC控制的船舶輪機員安全報警系統(tǒng)

摘  要

二十世紀九十年代以來，計算機的不斷發(fā)展引發(fā)了各個領(lǐng)域的革命性變革。航運界也受其影響，使得現(xiàn)代航運對船舶自動化程度和信息集成程度的要求也越來越高。為了適應(yīng)現(xiàn)代自動化機艙的要求，PLC控制逐漸取代繼電接觸器控制成為船舶機艙控制的主要環(huán)節(jié)，使控制系統(tǒng)更加安全、迅速、可靠。 船舶在正常航行過程中，機艙出現(xiàn)故障經(jīng)常需要輪機員下去對主機，輔機等設(shè)備進行維修和保養(yǎng)，由于現(xiàn)在大多數(shù)船舶采用的是無人機艙的模式，所以在機艙工作的數(shù)量就很少。故而當輪機員進入機艙工作就需要有可靠的監(jiān)測報警系統(tǒng)，傳統(tǒng)的繼電器控制的輪機員安全報警器，雖說能夠提供報警但是其容易發(fā)生故障且不易被察覺。然而采用PLC控制這能使輪機員報警系統(tǒng)的安全系數(shù)大大的提高，從而使輪機員的工作更加安全可靠。上述設(shè)計滿足了《2006鋼質(zhì)海船建造入級規(guī)范》的迅速、實時、可靠、直觀等要求。所以用PLC控制輪機員報警器就能夠使輪機員在機艙工作地安全系數(shù)得到大大的提高

Abstract

Since the 1990s, the computer has developed unceasingly has initiated each domain revolutionary transformation. The shipping interest also receives its influence, causes the modern shipping is also getting higher and higher to the ships automatically and the information integration degree request. In order to adapt the modern automation engine room request, the PLC control substitutes gradually following the electrical pick-off control into ships engine room control key link, causes the control system to be safer, to be rapid, is reliable. The ships in the normal navigation process, the engine room present the breakdown to need the marine engineer to get down frequently to the main engine, equipment and so on auxiliary engine to carry on the service and the maintenance, what because the present majority ships use is the unmanned engine room pattern, therefore are very few in engine room work's quantity. Therefore works as the marine engineer enters the engine room work to need to have the reliable monitor alarm system, the traditional black-white control marine engineer safety alarm apparatus, although can provide the warning, but it easy to break down and was realized not easily. However uses PLC to control this to be able to cause the marine engineer alarm system's safety coefficient big enhancement, thus causes marine engineer's work to be safer reliably. The above design has satisfied "2006 Steel Sea boats Construct Into Level Standard" rapidly, real-time, reliable, direct-viewing and so on requests. Therefore controls the marine engineer alarm apparatus with PLC to be able to enable the marine engineer to have the big enhancement in the engine room job site safety coefficient
