摘要
当下,随着铁道信号的数字化和计算机化的不断推进,铁路运力大幅提升,现场出现了很多超过3个出站口的车站,有的甚至多达7～8个出站方向.原有的带3个表示器的出站信号机已不能适应这些新变化.因此,以DS6-K5B型计算机联锁为例设计-种基于数码管的新型出站信号表示器以及相应的控制电路.该表示器不仅简化以往的信号表示器电路,实现数字化控制,而且还在表示含义上具有一定的容错能力.这种设计方案可以较好地解决出站信号机开放时的方向问题.
With the rapid development of digitization and computerization, Chinese railway transportationis increasing remarkably, and stations with more than three exit directions come to emerge on the railway,some with even seven to eight exit directions, which has made the former starting signal with only threeindicators inadaptable to the new changes. Therefore, this paper refers to DS6-K5B Interlocking Systemto design a new departure track indicator and control circuit based LED. This new indicator not onlysimplifies former control circuit of indicator to fulfill digitalized control, but has fault tolerant ability ofdisplay. The design shows that using the LED indicator could better solve the problem of distinguishingdirections when starting signal is open.
