    • An apparatus for monitoring the operation of a railroad train includes two on-board units which collect and utilize data for ultimate transfer to a portable unit which can be carried onto and off of the railroad train. One of these on-board units operates under microcomputer control to compute speed, acceleration/deceleration, and distance traveled data and to store such computred data for subsequent transfer to the portable unit. The other on-board unit acquires additional data under separate microcomputer control. This data acquisition retrieves either binary or analog data, or both, and stores it in the acquiring on-board unit for later transfer to a separate memory in the other on-board unit for subsequent transfer to the portable unit. Power failure detection circuits are also implemented to insure the microcomputers are initiated in respective determinate states.
    • 用于监视铁路列车操作的装置包括两个车载单元,其收集和利用数据以最终传送到可携带到铁路列车上的便携式单元。 这些机载单元中的一个在微机控制下运行,以计算速度,加速/减速和行驶距离数据,并存储这样的计算数据,以便随后传输到便携式设备。 其他车载单元在单独的微机控制下获取附加数据。 该数据采集检索二进制数据或模拟数据,或两者兼容,并将其存储在采集板载单元中,以便稍后传送到另一个板载单元中的单独存储器,以便随后传输到便携式设备。 还实现了电源故障检测电路,以确保在相应的确定状态下启动微型计算机。
