| Radio blocking center(RBC) is a key ground device of Chinese train control system level 3(CTCS-3), which is technically sophisticated and expensive. RBC decides the train ground communication effect, depending on its reliability and security. It gains Movement Authority for running trains and ensures a solid security of the express railway. For different RBC manufacturers in engineering design and implementation, their products vary in interface capacity and control ability, so it’s vitally important to use and configure an appropriate number of RBCs for a new high-speed railway or a large hub station. It determines the cost and subsequent operation security.The thesis studies the data forwarding of RBC in CTCS-3, clearly revealing how RBC communicates with CTCS and other subsystems. The thesis analyzes how much RBC relies on global system for mobile communications-railway(GSM-R) network configuration in order to understand how GSM-R network configuration affects RBC settings. It studies essentially the working principle, key working points, interface capacity, control ability, maintenance extension capability, with a reference to the Zhengzhou-Xi’an railway’s engineering design and analysis, to put forward the deployment location, control range, cut-off points, and train-ground communication of RBC for finding out the working principle of RBC and its numbering method.Currently, there is no railway station in China deployed with more than one RBC, but it is normal in future that a large station or a hub station will be deployed with two or more RBCs. The thesis puts forward three deployment plans, which is unprecedented in China. It takes Xi’an North Railway Station as an instance, setting an example for other relevant cases in China. |
