文章将铁路并线分为了3种不同的类型,以CTCS-3级列控高速铁路并线为例分析了铁路并线区域的业务量需求。引入GRRU(数字光纤直放站)技术,对不同并线类型提出了相应的网络规划方案,从频率规划难度、干扰情况、切换、可靠性和建设成本等方面对方案做了分析比较,从而得出既能保证铁路运营安全可靠又能节省投资成本的最优方案。
文章將鐵路併線分為瞭3種不同的類型,以CTCS-3級列控高速鐵路併線為例分析瞭鐵路併線區域的業務量需求。引入GRRU(數字光纖直放站)技術,對不同併線類型提齣瞭相應的網絡規劃方案,從頻率規劃難度、榦擾情況、切換、可靠性和建設成本等方麵對方案做瞭分析比較,從而得齣既能保證鐵路運營安全可靠又能節省投資成本的最優方案。

The paper divides the co-line regions into three types, and gives a detailed analysis of business requirements of the CTCS-3 high-speed railway co-line regions. GRRU technology is introduced in and provides relevant network planning programs for different co-line types. By comparing with the programs from difficulties of frequency planning, interference status, switching, reliability, and cost of the constructions and so on, it hence works out an optimal program both for ensuring the safety and reliability of railway operation and reducing investment.
