摘要:ZPW-2000A(UM)移頻自動閉塞是以移頻軌道電路為基礎的,擁有世界優秀技術的一種新型自動閉塞,它在確保區間行車安全的同時,在提高區段通過能力上,有著非常顯著的效率。ZPW-2000A(UM)移頻自動閉塞是以移頻軌道電路為基礎的自動閉塞,它選用頻率參數作為控制信息,采用頻率調制的方法,將低頻信息(F0)調制到較高頻率(載頻f0)上,以形成振幅不變、頻率隨低頻信息的幅度作周期性變化的調制信號。將此信號用兩根鋼軌作為傳輸通道來控制通過信號機的顯示,達到自動指揮列車運行的目的。35591
ZPW-2000A無絕緣移頻自動閉塞是在UM71無絕緣軌道電路技術的基礎上,結合國情,進行提高系統安全性、系統傳輸性能及系統可靠性的技術再開發。不但抑制了UM71系統在傳達時需擁有的安全性及傳輸長度上具有的諸多矛盾,還可以實現全程斷軌檢查軌道電路,調諧單元斷線檢查,拍頻干擾防護等技術難題。所以ZPW-2000A無絕緣移頻自動閉塞系統在提高了抗干擾能力的同時延長了軌道電路的長度。本次設計本應該對ZPW-2000型無絕緣移頻自動閉塞實驗系統結構設備組成,自動閉塞系統在站間站內的測試、應用和軌道電路的調整都做出詳細的分析,但因為時間、條件有限,重點設計ZPW-2000A無絕緣移頻實驗系統的內部電路結構、系統運行程序編寫、室內機柜布置設計。

ZPW type - 2000 No Insulation Frequency Shift Automatic Block System Design
Abstract:ZPW-2000A (UM) frequency shift automatic block is to frequency shift track circuit as the foundation, with the world top technology is a new type of automatic block, in ensuring the interval driving safety at the same time, in improving section by ability, efficiency is very significant.ZPW-2000A (UM) frequency shift automatic block is to frequency shift track circuit based automatic block, it selects the frequency parameters as control information, using method of frequency modulation, frequency information (F0) modulation to high frequency (carrier frequency f0) on, to form the amplitude unchanged, frequency with the amplitude of the low frequency information as periodic variation of the modulation signal.Will this signal with two rails as the transmission channel to control through the signal display, to achieve automatic control of train operation.

ZPW-2000A non insulated frequency shift automatic block is in of UM71 jointless track circuit technology based on, combined with national conditions, to improve system security, system transmission performance and reliability of the technology and development.Not only inhibited the UM71 system in communication with the security and transmission length with many contradictions, also can realize the whole broken rail detection track circuit, tuning unit break check, beat frequency interference protection and other technical problems.So the ZPW-2000A shift frequency automatic blocking system to improve the anti-interference ability and prolong the length of track circuit.The design should have of ZPW-2000 jointless frequency shift automatic block equipment of the experimental system structure composition and automatic block system adjustment in the station between the station test, application and the track circuit to make detailed analysis, but because of the limited time and condition. ZPW-2000A frequency experiment system of focus shift is internal circuit structure and system running the program compiling, indoor cabinet layout design.
