3UM71站内电码化电路原理3·1京秦线UM71站内电码化电路的特点1.采用25Hz相敏轨道电路叠加UM71信息的发码方式。2.正线电码化采用预叠加方式发码(即压入本区段,运行前方的相邻区段就开始发码),侧线电码化采用压入叠加方式发码。3.电码化电路发送器载频:S行使用2000Hz,X行使用17
3UM71 Station Coded Circuit Principle 3.1 Beijing-Qinhuangdao UM71 station code circuit features 1. Adopt 25Hz phase sensitive track circuit superimposed UM71 information code. 2. The main line of code using pre-stacked code (that is pressed into the sector, adjacent to the front of the operation began to send code), the side of the code using push-stacked code. 3. Coded circuit transmitter carrier frequency: S line use 2000Hz, X line use 17
