MUSER Real-time Observation And Scientific Data Visualization Research And Implementation

This paper studies the real-time visualization of observation data of MingantU SpEctral Radioheliograph and analyzes the visual real-time display demand of MUSER observation data in detail.According to the visualization requirements of the MUSER project for observing data,the following research are carried out:1.We get a detailed investigation on astronomical observation data visualization technology,and analyze the characteristics of these technologies.At the same times,this paper analyzes the visualization requirements of MUSER observation data in detail and puts forward some key technology for the visualization demand of MUSER.2.We research on real-time display technology of multi-screen visualization for the local visualization demand of MUSER observation data,design and implement a multi-screen visualization real-time display system.Amplitude images are rapidly synthesized under Linux system by the multi-threading technology,multi-screen programming technology,message-oriented middleware technology,rapidly imaging technology base Qt library,etc.And amplitude images can be displayed by more displays in real-time.3.According to the demand of Beijing Observatory and KunMing Observatory need to monitor local observation data in real-time,we design and implement a remote visualization real-time display system for MUSER observation data.To achieve amplitude images remote real-time display by many technologies such as the WebSocket technology,message-oriented middleware technology,rapidly imaging by multi-threaded,JS technology,etc.4.Based on the above research,the prototype systems are put into using on MUSER observation station,and obtains a good result.The systems can visualization display a frame MUSER observation data within 5 seconds,the result indicates that the systems can satisfy the requirements of real-time demand of MUSER.Overall,this paper implements visualization of MUSER observation data in real?time.The research work in this paper has a reference value for the data visualization in radio astronomy field and other scientific fields that need data visualization.
