【摘要】 本文针对火车站集中使用近百面时钟的实际情况,提出了利用586计算机通过金字塔式控制方法进行集中管理,解决塔钟、站台钟、厅内石英钟等近百面时钟的走时不同步问题。采用GPS(The Global PositioningSystem)全球定位系统作为标准时间源,计时精度可达1微秒,并且没有累计误差。更多还原

【Abstract】 This paper bring forwards PYRAMID control method to manage clocks on railway station and solves timing no synchronism problem of tower clock, station clock, quartz clock etc. The system adopt GPS (The Global Positioning System ) to standard time source, time precision is 1 μs and no accumulative tatal error.更多还原
