Abstract
Section blocked is an important technology to ensure train safe running and raise driving efficiency of section, track circuit is the base of section blocked system. Based on the technology of UM71 non-insulated, track circuit and localized it, ZPW-2000A non-insulated frequency-shift automatic block system is introduced, bines national conditions with the analysis of safety and reliability and adopts the design idea from UM71 system. This paper mainly designs the ZPW-2000A frequency-shift automatic block system of Gaocun station in accordance with the theory and relevant design standard of this system.
The design drawings and drawing illustrating are two big parts of this design. The main drawings are as following: section signal layout diagram of Gaocun station equipment layout diagram of frequency-shift posite rack, blocking section circuit of 3961G, 3948G, and 3947G, redundant circuit of down N+1 and so on. This paper mainly discusses the theory and form of ZPW-2000A frequency-shift automatic block system; also studies the signal lighting circuit, red light transfer circuit and small rail access conditions at down departure point, up third approach section and down second departure section. The design conforms to the theory of ZPW-2000A; the method and process of this meets the railway signal design norm.
