在LED大屏幕上实时显示天文时间和电网频率的方法
摘要：
本发明公开了一种在LED大屏幕上实时显示天文时间和电网频率的方法，包括以下步骤：①设置天文时钟NTP输出口IP地址，将天文时钟NTP输出口与OPEN3000系统主网交换机连接；②将OPEN3000主网交换机网口与LED大屏幕控制机连接；③OPEN3000系统将采集到的实时电网频率以FTP的方式发送给LED大屏幕控制机；④LED大屏幕控制机接收FTP文件。该方法利用自动化主站机房内的OPEN3000系统与现有LED大屏幕控制机对时并将OPEN3000系统采集到的电网频率一并显示在LED大屏幕上，解决了调控人员对天文时间和电网频率的需求，切实有效的将天文时间和电网频率与调度大厅LED大屏幕融为一体，整齐美观，大大提高了调控人员的工作效率。
摘要（英）：

The invention discloses a method for displaying astronomical time and power network frequency on a large LED screen in real time. The method comprises the following steps: (1) setting an IP address of an astronomical clock NTP output port, and connecting the astronomical clock NTP output port with an OPEN3000 system main network switch; (2) connecting an internet port of the OPEN3000 main network switch with a large LED screen control machine; (3) transmitting the acquired real-time power network frequency to the large LED screen control machine in an FTP mode by virtue of the OPEN3000 system; and (4) receiving an FTP file by virtue of the large LED screen control machine. According to the method, the time is checked by utilizing the OPEN3000 system in a machine room of an automatic master station and the conventional large LED screen control machine, the acquired power network frequency is displayed on the large LED screen by virtue of the OPEN3000 system, the requirements on the astronomical time and power network frequency caused by regulators are met, the astronomical time and power network frequency are practically and effectively fused with the large LED screen in a scheduling hall into a whole, the appearance is neat and attractive, and the working efficiency of the regulators is greatly improved.
