    • The present invention discloses a long distance system capable of performing time synchronization with high precision at the minimum cost by transmitting/receiving a time synchronization signal using one of a power line and a communications line that are commonly installed and used between sub-systems constituting a predetermined long distance system, and a time synchronization method performed in the long distance system. The long distance system includes a control sub-system and a plurality of sub-systems. The control sub-system includes a control unit, an atomic clock, and a synchronization generator. The control unit corrects the time of the atomic clock using satellite navigation signals received through a satellite navigation, and the synchronization generator generates a time synchronization signal using time corrected of the atomic clock. Each of the sub-systems includes a time synchronization terminal that is connected with the control sub-system through at least one of the power line and the communications line and performs time synchronization using the time synchronization signal received through one of the power line and the communications line.
    • 本发明公开了一种长距离系统,其能够以最小成本以高精度进行时间同步,通过使用在构成一个或多个子系统的子系统之间通常安装和使用的电力线和通信线路之一来发送/接收时间同步信号 预定长距离系统,以及在长距离系统中执行的时间同步方法。 长距离系统包括控制子系统和多个子系统。 控制子系统包括控制单元,原子钟和同步发生器。 控制单元使用通过卫星导航接收到的卫星导航信号来校正原子钟的时间,同步发生器使用原子钟校正的时间产生时间同步信号。 每个子系统包括时间同步终端,其通过电力线和通信线路中的至少一个与控制子系统连接,并使用通过电力线和通信线路中的一个接收的时间同步信号来执行时间同步 通信线路。
