With the development of railway technology, trains

The speed and load are greatly improved, which puts forward higher requirements for the safety of train operation to ensure the safety and smoothness of trains. There are many technical means to ensure the normal operation of trains, among which the track circuit is the most important (1**), and ZPW-2000, as an uninsulated frequency shift automatic block system, is the most advanced uninsulated automatic block system (2**). It will play a role in the technical development policy of China's railways. In China's railways, locomotive signals are proposed as the main operation signals.

Hening high-speed railway is the first passenger dedicated line in China and an important part of China's expressway network. This paper mainly expounds the composition and principle of ZPW- 2000 non-insulated track circuit system, and briefly explains the knowledge of (a) equipment arrangement of cabinets in (3 * *) area and (b) zero-floor wiring.

This design is based on the railway signal design specification and combined with the specific situation of racecourse station. Automatic block and 18 turnout are adopted in the station to meet the requirements of speed increase. The purpose of this project design is to (A)(4**) complete the engineering drawing of Ma Chang Station of Hening Line by learning and mastering AUTO CAD, including (a) signal layout of station and railway section, (b) indoor equipment layout, (c) track circuit diagram of station and railway section, (d) signal display and coding sequence table, and (e) layout and wiring diagram of each equipment cabinet. And (B) (5**) can master (a) how to change the set of directional relays in stations and train sections, (b) the design of drivers, and (c) how to calculate and configure compensation capacitors.

Firstly, this paper introduces the development status and research significance of frequency shift automatic block at home and abroad; Secondly, the engineering design is expounded from the whole to the part in combination with the design drawings, and the overall design scheme is determined in combination with the plane layout of the station and the depot; Then the overall layout of the whole indoor equipment is carried out; Then the structure and function of track circuit in train section and station are designed. Finally, the wiring layout of each cabinet is briefly explained.

Note: (1 * *-5 * *) is the connection of grammatical structure (ellipsis, demonstrative pronoun, juxtaposition, etc. ), (A, B, C, D ...), etc. It is a connecting symbol of coordinate grammatical components. If you can understand it, you can remove all the letters or numerical symbols in brackets and correct them directly according to the original structure.
