2、輔機等設備進行維修和保養(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[關鍵詞]船舶輪機員安全；監(jiān)視報警系統(tǒng)；PLC；繼電器控制BasedonPLCco
