【導(dǎo)讀】除文中已經(jīng)注明的內(nèi)容外，本論文不包含其他個(gè)人已經(jīng)發(fā)表或。撰寫(xiě)過(guò)的研究成果。對(duì)本文的研究做出重要貢獻(xiàn)的個(gè)人和集體，均已。在文中作了明確說(shuō)明并表示謝意。如今，鐵路已經(jīng)遍及世界各地，貫穿了我們的生活。路無(wú)法正常運(yùn)行甚至發(fā)生事故。本課題的研究目的和意義就是設(shè)計(jì)一套信號(hào)燈報(bào)。一時(shí)間對(duì)發(fā)生故障的信號(hào)燈進(jìn)行維修，以保障鐵路的正常運(yùn)營(yíng)。由人騎著馬在前面引導(dǎo)火車(chē)運(yùn)行。用手勢(shì)信號(hào)來(lái)指揮列車(chē)前進(jìn)或停止。后來(lái)隨著列車(chē)速度的不斷提高，信號(hào)燈。這種臂板式信號(hào)機(jī)有兩種顯。示：水平位置表示停車(chē)信號(hào)，向下傾斜45度表示進(jìn)行信號(hào)。夜間仍用紅色燈光。表示停車(chē)，但改用綠色燈光表示前進(jìn)。行，信號(hào)燈監(jiān)控系統(tǒng)也在不斷的向自動(dòng)化、智能化發(fā)展和改進(jìn)。顯示各信號(hào)設(shè)備的狀態(tài)或采用報(bào)警繼電器，用計(jì)算機(jī)監(jiān)控各信號(hào)。表的《新型站內(nèi)信號(hào)燈斷絲定位報(bào)警系統(tǒng)》。這些技術(shù)的缺點(diǎn)是，占用空間大但檢測(cè)的點(diǎn)數(shù)少，距離短而且造。16路信號(hào)燈循環(huán)進(jìn)行檢測(cè)。正弦信號(hào)可能采集
