Research on the Reconstruction Scheme of the Section Block System of the Normal-Speed Railway
In response to the technical transformation of the signal section block system caused by the elevated transformation of normal-speed railway stations,in order to reduce the interference of existing line signal transformation on railway transportation,ensure the personal safety of railway operation,maintenance and construction personnel,combined with the principle of signal system section block circuit and experience in crossing engineering design,three automatic block transformation design schemes are proposed,and the specific design and transformation content of section block equipment in different schemes is described in detail.Comparative analysis is conducted on differences in construction conditions,test conditions,project duration,project investment,and operational safety,and corresponding recommended solutions are proposed based on different application scenarios in engineering design,in order to reduce the impact of existing line signal renovation on railway transportation and ensure the safety of vehicles and personal property.
