64D闭塞信息传输光、电通道快速切换装置的研制

Research and Development of Fast Switch Device of Optoelectronic Communication Channels for Transmitting 64D Block Information

各车站间光缆传输线路多为单一路径敷设,未形成安全冗余通道或环路连接,存在闭塞安全信息单路传输安全风险。通过研发光、电通道快速切换装置,在光通道突发故障情况下,通过快速切换装置将传输通道切换至冷备用的电通道进行传输,解决光通道与电通道快速切换、互为备用的技术难题,确保运输生产安全。

Station optical cable laying transmission lines into a single path, connection is not safe redundant channels or loops, block single transmission security information security risks. Quick crossover device of optical channel through research and development, optical channel under e- mergency circumstances, by quick crossover device of transmission channel switch to cold standby electricity transmission channel, solution channels and channel switch quickly and spare each other technical problems to ensure transport safety.
