Abstract

The design completed the G station ZPW-2000A closed-loop code design (downstream) mainly based on the principle of ZPW-2000A closed-loop coding technology and the design of engineering graphics specifications, terms of the necessity of closed-loop checking code, key technology, circuit principle and main design principles are described.

Two parts of the drawings and specifications are included in the G station ZPW-2000A closed-loop code design. Drawing part includes a total of 12: G station signal layout plan; G station downstream forward pick-up approach coding diagram;

G station downstream forward departure approach coding diagram; G station downstream positive line IG coding diagram; G station side track (3G, 5G, 7G) coding diagram; G station closed-loop coding N+1 redundancy send diagram; G station closed-loop coding cabinet equipment layout; G station downstream positive line pick-up coding detector diagram; G station downstream positive line departure coding detector diagram and shares road code of detection circuit diagram. The description part has carried on the detailed instructions to each drawing. The signal, carrier frequency configuration and compensation are described in signal layout plan. Relating to the relay circuit and their working principle are introduced in downstream forward pick-up approach coding and departure approach coding diagram. Cabinet equipment layout introduced frequency shift cabinet, detection cabinet and comprehensive cabinet. Carrier frequency switching and hair code channel are introduced in N+1 redundancy.

G station ZPW-2000A closed-loop code is designed to meet the “code for design of railway signal (TB 10007-2006)” requirement.

Key Words: ZPW-2000A, Closed-loop code, Coding detection, N+1 redundancy
