1、 摘 要随着列车的提速与铁路事业的不断发展，为满足机车在站内能通过轨道接收到移频机车信号信息的要求，站内轨道电路必须实施电码化。站内电码化是一种实现在车站内由相应轨道电路转发或叠加机车信号信息来确保铁路行车安全的重要技术。本次17号站的设计选用了ZPW-2000A型自动闭塞制式并实施预叠加。ZPW-2000A型可以有效的解决调谐区的断轨检查问题，缩短了调谐区分路死区长度并实现了对调谐单元的断线故障检查，提高了轨道电路的传输长度，使轨道电路更加的稳定。在运行过程中列车必须要连续不断的收到地面发送的机车信号信息，故采用预叠加电码化技术，以减少机车掉码现象。17号站逐段预叠加ZPW-2000A（上行

15、电码化。叠加式是在电码化过程中在轨条内同时发送动作轨道电路和动作机车信号信息的方式，移频信号可以以叠加的方式发往轨道。车站股道电码化自在1988年起在全路推行以来，因当时没有提出适应超速防护装置的需要，即对发码连续性的要求，只是在满足列车运行速度100km/h以下时，保证机车信号的工作，同时解决轨道电路的自动恢复问题，但不符合预叠加电码化的要求。由于列车运行速度的提高，其制动更加困难，冒进信号的可能性比较大。而当时有的向机车信号或超防设备提供信息的电码化技术和设备已不能满足提速列车的要求，要满足正线区段电码化在时间上不允许有中断的时间，原来适用的车站股道电码化的叠加发码方式必须改为预先叠加发码的方式。采用预先叠加发码的发送盒有两路独立输
