库尔勒下行到发场电码化特殊改频电路的改进

针对反向接车进路有2组及以上顺向道岔时,传统电码化改频电路无法区分是否需要改频的问题,依据库尔勒下行到发场电码化设计,对既有改频电路进行改进,利用3个电码化接车进路中改频电路的特殊设计,对改频的时机实现了准确的判定,保证发送器正确改频,为电码化改频电路设计提出了一种新思路。

Improvement of Special Coding Frequency Conversion Circuit in Down Receiving-departure Yard of Korla Station

The traditional cannot distinguish whether or not to conduct frequency conversion in the case that there are two and more forward turnouts in the route of reversal train receiving. Thus, the existing code frequency conversion circuit is modified according to the design of coding circuit in the down receiving-departure yard of Korla station. By using a special design of frequency conversion circuits in three routes for train receiving, the timing of frequency conversion is determined accurately, which can ensure the correctness of frequency conversion of the sender, offering a new idea for the design of frequency conversion circuit as well.
