【摘要】 系统主要实现列车运行时刻信息的自动采集以及列车与地面调度所的远程通信。为了实现系统的可靠性设计,提出了基于双模冗余混联结构的系统可靠性模型,并采用低耦合和高聚合的层次结构模型,实现了通信软件的可靠性设计。运行实践证明,该系统稳定可靠,达到了设计要求。更多还原

【Abstract】 The Systems primary purpose was to collect the train running information and to setup the mobile communicationbetween the train and the control center. To ensure reliability of the System, a mixed reliability model with serial and parallelconnections based on double redundant strategy was provided for the System design and a layered structure model with lowcoupling and high aggregation was applied in the communication software design. Tested by the practice, the System wassteady-going and reliable.更多还原
