[Abstract]:Based on the research on real-time visualization of observation data of MingantU SpEctral Radioheliographer, this paper analyzes the requirement of real-time visualization of MUSER observation data. In this paper, the following research is carried out: 1, to investigate some of the main astronomical visualization technologies in the field of astronomy, and to further analyze the characteristics of these technologies. The visualization requirements of the MUSER observation data are analyzed in detail, and the visualization requirements of the MUSER observation data are analyzed. The key technology of visual processing of MUSER observation data is put forward. According to the field visualization requirement of MUSER observation data, the real-time display technology of multi-screen visualization is studied. This paper designs and implements a set of prototype system for visualization and real-time display of MUSER observation data, which adopts multi-thread technology, multi-screen programming technology, message middleware technology and rapid imaging technology based on QT, etc. This paper realizes the quick synthesis and display of MUSER real-time data visibility amplitude chart under Linux, and can display. 3 in the form of multi-screen, aiming at the demand of real-time monitoring of field observation data in Beijing, Kunming and other remote places, such as Beijing, Kunming and so on. A prototype system of remote visualization and real-time display of MUSER observation data is designed and implemented, which adopts WebSocket technology, message middleware technology, multithread fast imaging technology and so on. The remote real-time display of spectrum chart and visibility amplitude chart of MUSER observation data is realized. On the basis of the above research, the prototype system is put into actual operation of MUSER observation station, and good results are obtained. The prototype system can realize the visualization of MUSER-I one-frame observation data within 5 seconds, which can meet the real-time requirements of MUSER observation data visualization. In this paper, we have realized the visualization of MUSER observation data in real time. The research work in this paper has some reference value for the research of data visualization technology in radio astronomy and other scientific fields.
