Title
(EN) Pocket communication method and machine controlling system
(ZH) 分组通信方法和存储数据共有系统
Abstract
(EN)
A plural station memory data sharing system in which packets are sent/received between plural stations interconnected through communication lines. Each station has a unique station address value, and the time is made to correspond to each station address value. The internal clock (39) in each station indicates the same time and circulates from time TOO to an upper limit time TM. When the internal clock (39) indicates a time corresponding to the station address value of a station, data stored in a memory at the address position corresponding to the station address value is buried in a packet and the packet is sent through a communication line. An allowance time error sensing circuit (34) compares the calculated correct time of the internal clock of the station and the time indicated by the internal clock, If the error is out of an allowance range, the internal clock (39) is forcedly calibrated to the correct time.

一种多台存储数据共有系统,在由通信线路连接的多台之间发射接收分组。在各台上设定固有的台地址值,使各时刻与各台地址值对应。台内的内部时钟(39)都显示同一时刻,并且从时刻T00到上限时刻TM进行循环。当内部时钟(39)显示与某个台的台地址值对应的时刻时,将在与台地址值对应的存储地址位置上的存储器内的数据嵌入分组中,并将这个分组在所述通信线路上发射出去。允许时刻误差判定电路(34)比较算出的本台的内部时钟的正确时刻和内部时钟所示时刻,当这个差超过允许范围时,强制地将内部时钟(39)校正到正确的时刻。
