列车编组中越“标”预警系统的逻辑设计

The Determination and Simplification of Pre-warning Logic Network for Surpassing the Marking Stakes in Train Marshalling

本文以列车编组时存在的越“标”问题为例,讨论了越“标”预警系统所需要的逻辑开关网络,并以此网络为基础,设计了整个预警电路系统,调试结果表明设计方法合理、可行。

Taking the problem of surpassing the marking stakes in train marshalling as an example, the paper discusses how to caculate and simplify the logic switch network which is needed in the pre-warning system for surpassing the marking stakes,according to the concrete operation requirments. Based on the determination of the network mentioned above, the whole pre-warning circuit system with such network acting as the core in it is described, so a solution is provided for this problem which needs to be solved urgently in trian marshalling.
