利用VB控件监视与管理时间服务器

Realization of Monitoring and Management of TimeServer Using VB Component

在极轨气象卫星数据接收系统中,时间统一性对气象卫星资料接收质量有着重要影响。因此需要时间服务器为系统提供统一的时间基准,从而保证卫星资料的完整按时接收。由于GPS时钟具有稳定、准确的特点,将其作为时间服务器的信号源。为了保证GPS时间服务器正常工作,有必要对其进行状态监视。在VB6.0环境下,利用串口通信成功实现了对时间服务器的监视、管理功能。监视功能为时间服务器故障的发现、定位与记录提供了重要依据。管理功能包括参数查询、功能设置等,方便用户对时间服务器的操作。

Time synchronization has a major impact on the quality of images received by satellites in the polar orbiting meteorological satellite data acquisition system. Therefore, TimeServer is needed to provide criterion time for the system to ensure complete reception on schedule. The GPS clock is used as the reference source of TimeServer for its stabilization and accuracy. In order to ensure that the GPSTimeServer works normally, it is necessary to monitor its status. The monitoring and management functions through the serial communication on the TimeServer is based on the Visual Basic 6.0. The monitoring function provides an important basis for fault finding, troubleshooting, and recording. The management functions include inquiry and subfunction setting, which is convenient for users to operate.
