Abstract

The invention discloses a railway signal data network structure and a connection method thereof. The railway signal data network structure comprises a plurality of signal equipment sites positioned on a railway line, a left switch, a right switch and various application equipment in each site, and a left optical fiber and a right optical fiber penetrating though different physical paths of each site. The left switch and the right switch of each site are connected in series respectively via the left optical fiber and the right optical fiber according to a way of combining a multi-section jump connection channel with a multi-section neighbor connection channel to form a left looped network and a right looped network, respectively, both the jump connection channel and the neighbor connection channel use two-core single mode fibers in the optical fibers, the limited value of the length of each section is not more than the preset minimal length of a relay needing to be additionally arranged of the railway signal data network, and thus arrangement of the delay is avoided, and overall construction costs and maintenance costs of the railway signal data network are reduced.

Description

technical field [0001] The invention relates to the technical field of railway signals, in particular to a railway signal data network structure and a connection method thereof. Background technique [0002] At present, my country's railways with a speed of 200 kilometers per hour and above and intercity railways with a speed of 120 kilometers per hour and above generally adopt CTCS-2 or CTCS-3 train control systems, which require the establishment of railway signal safety data networks (hereinafter referred to as "Signal data network"), which carries the secure data transmission and information interaction between the ground-related equipment of the train control system. [0003] Existing signal data network technical solutions for reference figure 1 As shown, the concentrated setting points of signal equipment along the CTCS-2 or CTCS-3 railway (including stations, signal relay stations, line stations, bullet train depots, bullet train stations, wireless block centers, tem...
