Zpw-2000a Track Circuit Applied Research

The paper introduces and analyses the ZPW-2000A Type Jointless Audio Frequency-shift Modulate Track Circuit technology applied in Railway Signal Engineering Construction Project systematically.The system is further developed and engineered for enhancing the system safety, system transmission length and system reliability on the basis of UM71 jointless track circuit and combing the specific situation of China, such development made the ratio of the performance.The signal technology is applied successively in recent years.The author tries to be practical by gathering and consulting massive information and data,relying on the basis of construction experience acquired during the period of Year 2004-Year 2005.The author made some adjustments on design and construction technique for track circuit section,so the operators will improve carrying capacity and operating efficiency.During the constructing stage of Railway Electrical Service Engineering Project,the purpose of the customers and designers can be carried out ultimately.The paper only discusses how to.apply the ZPW-2000A Type Jointless Audio Frequency-shift Modulate Track Circuit technology during constructing stage.The author tried his best to combine theory with practice,and he focused on the practicability. The paper can be divided into five chapters.At the first chapter, the author gave us a general outline of the Railway and the Railway Signal Engineering Construction Project in our country.It provides the foundation to the whole paper.At chapter 2, the author introduced the mode of establishing and operating the ZPW-2000A system on the side of the project organization. This leads to the application of ZPW-2000A system technology.At chapter 3, the author detailedly analysed and summarized how to build and debug the ZPW-2000A system according to the construction procedure. The introduction to the practice of the system relates to many exclusive items such as idiographic affairs, engineering technical and material terms for Railway Signal...
