The cab signal fault diagnosis problem is combined with the pattern matching problem on the ba-sis of this conclusion. A cab signal fault diagnosis model based on Multiple Patterns Matching Algorithm DFSA(Deterministic Finite State Automata) is proposed.

• 并在此基础上将模式匹配问题与机车信号的故障诊断问题相结合,提出了基于多模式匹配算法DFSA(Deterministic Finite State Automata)的机车信号故障诊断模型。
