摘　　要：ZPW-2000A型无绝缘移频自动闭塞是在法国UM71无绝缘轨道电路技术引进、国产化基础上,结合国情进行的技术再开发。在轨道电路传输安全性上,ZPW-2000型无绝缘轨道电路已具备全程断轨检查、调谐区≤5m的分路死区、调谐单元断线轨道电路隔离性能丧失的检查、钢轨对地不平衡条件下的列车分路及断轨检查等。成为我国目前安全性高、传输性能好、具有自主知识产权的一种先进自动闭塞制式,为"机车信号做为主体信号"创造了必备的安全基础条件。ZPW type-2000 automatic block is an internationally advanced level of new automatic block, it is to ensure safety, improve the interval, the carrying capacity plays a very significantrole. ZPW type-2000 frequency shift automatic block has many advantages, it overcomes the UM71 system in transmission safety and transmission length , solve the problems exsting in the whole course of track circuit fault zone, tuning, dead zone length tuning unit break check, frequency interference protection,etc. Extend the length of track circuit.The MCU and digital signal processing technology, improve the anti-interference ability. The design of ZPW type-2000 without insulation track circuit system structure, system of the circuit principle, system test track circuit and the adjustement and automatic block system in standing between the application within the station has made a detailed description of the key design.
