甚小型天线地球站数据采集系统的同步与线程管理

VSAT数据采集系统是整个VSAT应用中最关键的子系统，它直接影响其他子系统的性能；分布式的VSAT数据采集系统中实现精确时间同步和控制是至关重要的，只有通过对各采集站的时间同步才能使整个系统处于全局一致的状态，通过GPS和原子钟实现了系统的精确时间同步，并通过对任务线程的管理和调度实现了对数据的同步采集和处理，从而提高了数据采集和测量的精度，并为其他VSAT子系统应用奠定了基础。

Synchronization and Thread Managing of VSAT Data Collection System

The performance of VSAT data collection system directly affects the other subsystems of VSAT system, so it's the most important subsystem of VSAT application. In a distributed VSAT data collection system,precise time synchronization is very important, only by time synchronization all collecting stations can achieve a global consistent state. The precise time synchronization is realized by GPS and atomic clock and especially much attention is paid to study how to manage and schedule all task treads in the system to raise the precision of data collection and support the other subsystem of VSAT system.
