Design of Search Algorithm in Interlock Route's Hostile Signal

Zhu Geng1,2(1.Software College,Dongguan University of Technology,Dongguan 523808,China;2.College of Automation Science and Engineering,South China University of Technology,Guangzhou 510640,China)  
This paper analyzes the definition of route's hostile signal and the problem to dispose or generate it in railway signal computer interlock system.With the interlock route,it expounds the restriction relationship between hostile signal and route searching.Using directional graph of the railway station and mathematic knowledge of theory of graph and adjacency matrix,a k-steps route's hostile signal search algorithm and a k-steps route pervasion generating algorithm are put forward,whose processing flows are given out and are realized by a computer language like C.The algorithms are applied in material projects and simulated by an instance of a practice railway station.At last,a part of instance data of railway station route and its' hostile signal are given out with this algorithm.
