摘要:隨著城市軌道交通運(yùn)營線路的增多,需要傳輸網(wǎng)絡(luò)提供足夠容量的帶寬,并能為未來新增業(yè)務(wù)及線路增長預(yù)留出足夠的可擴(kuò)容空間。該文以A市軌道交通線網(wǎng)傳輸系統(tǒng)的建設(shè)為例,對線網(wǎng)傳輸系統(tǒng)進(jìn)行分析研究,比選了三種傳輸技術(shù)制式,提出了線網(wǎng)傳輸系統(tǒng)的構(gòu)建方案,并對軌道交通傳輸系統(tǒng)的建設(shè)進(jìn)行了探討。

Abstract: With the increase of urban rail transit operating lines, it is necessary for the transmission network to provide sufficient bandwidth capacity and reserve enough expandable space for future new business and line growth. This article takes the construction of the A city rail transit network transmission system as an example, analyzes and studies the network transmission system, compares three transmission technology standards, proposes a construction plan for the network transmission system, and discusses the construction of the rail transit transmission system.
Keywords: packet enhanced OTN; rail transit; network transmissionsystem; construction
1 線網(wǎng)傳輸系統(tǒng)的建設(shè)背景
隨著線路的增加,線網(wǎng)也日益擴(kuò)大,A市地鐵公司面臨著線網(wǎng)運(yùn)營統(tǒng)一指揮、線網(wǎng)運(yùn)營服務(wù)信息統(tǒng)一發(fā)布、線網(wǎng)維修綜合調(diào)度、線網(wǎng)應(yīng)急處置困難等一系列急待解決的問題。(剩余3517字)
