150MHz 单双工兼容制列车调度通信系统适用于铁路干线(包括山区多隧道区段)。通信方式:调度员与机车司机、车站值班员与机车司机之间,采用异频双工方式,其他用户间的通话采用同频单工方式。在隧道内采用经邻近车站转信,采用异频单工方式。系统构成:采用有线与无线相结合的链状网结构,车站与机车用无线,调度与车站间为有线,使用两对电缆传输。频率配置:采用150MHz 四频组制式,共配置4个四频组。呼叫方式:采用音声群
150MHz single-duplex compatible train scheduling communication system is suitable for railway trunk (including mountainous tunnel section). Communication: dispatchers and locomotive drivers, the station attendant and locomotive drivers, using different frequency duplex mode, the other users of the same frequency using simplex way. In the tunnel using the adjacent station to transfer letters, using different frequency single-mode. System composition: The combination of wired and wireless chain network structure, wireless stations and locomotives, scheduling and cable between the stations, the use of two pairs of cable transmission. Frequency configuration: The use of quad-band 150MHz standard, a total of four quad-band configuration. Calling method: using sound group
