摘要
采用现场总线互联技术的主机遥控系统由主机控制、主机安全、主机报警三个完全独立的子系统组成,各子系统现场总线在物理上完全独立,软硬件故障对通信可能造成的影响完全局限在本子系统内;各子系统大部分数据只在各自现场总线内部传播,少量数据相互交换,因此现场总线内部数据流量小,传输实时性好,可靠性高。
Main engine＇s remote-control system based on fieldbus interconnection technology has three fully independent subsystems, which are main engine control system, main engine safety system and main engine alarm system. These sybsystems＇ field bus is absolutely physically independent, software or hardware＇s fault can only influence its own subsystem. Most data of each subsystem just transmit internally, only a few data exchange with other subsystem, so the fieldbus has small data flow and contributes to good real-time transmission and high reliability.
