Visualization Display Method for MUSER Remote Monitoring Data Based on WEB Technology

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 real-time 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.
