文远程监控是天文研究的重要组成部分。为及时发现由于天气原因、电磁干扰、天线故障等导致的异常数据,提高数据处理的可靠性,我国明安图频谱射电日像仪迫切需要实现实时观测状态的远程监控。提出了一种基于WEBSOCKET技术的远程监控数据的可视化展现方法,并以观测过程中功率图和频谱图的实时展现为例进行了验证。实验表明,方法可满足实时监控数据可视化展现需求,并且改变了传统的现场监控模式,打破了地域限制,具有可靠性高、实时性好和扩充性广等诸多优点,提高了工作效率和设备利用率,对其它远程监控数据可视化展现系统有一定的参考价值。

Astronomical remote monitoring is an important part of astronomical research. To detect the distortion data caused by weather condition, electromagnetic interference and antenna malfunction in time and improve the reliability of data processing, it is the urgent demand for MUSER (Mingantu Ultrawide Spectral  Radio Heliograph, the original name is Chinese Spectral Radio Heliograph—CSRH) to realize the remote monitoring of the state of real time observation.  In this paper, we present a visualization method for MUSER remote monitoring data which is based on WebSocket technology.  And we use power and spectrum data in realtime visualization display as an example to validate.  The experimental results show that proposed method can meet the requirements of real-time observation monitoring of MUSER. It changes the traditional local monitor mode, breaks the region limitation and has series of advantages such as real-time response, maneuverability and extensibility.  At the same times, the proposed method improves the efficiency and equipment utilization. And there is a certain reference value to other remote monitoring and data visualization systems.
