对天文望远镜的观测数据或控制过程状态进行实时的图形化显示，是天文仪器研制过程中的一个重要环节。随着Linux操作系统在天文领域的广泛应用，如何开发基于LINUX图形界面的实时图形化显示系统成为一种迫切需求。针对我国明安图超宽频射电日像仪（Mingantu Ultrawide Spectral Radio Heliograph， MUSER，原名为中国射电频谱日像仪， CSRH）实时观测数据图形化显示的要求，给出了一种利用QT架构进行实时、多屏的图形化展现方法，并以互相关与自相关数据实时展现为例进行了验证。实验表明本方法完全可以满足MUSER实时观测监控的要求，并且具有简单、快捷、可移植性好等优点，克服了LINUX下X-WINDOW编程困难等难题，对其它望远镜设计类似功能有一定的参考价值。

To achieve real-time graphical display of observational data or control processes/statuses of an astronomical telescope is an important part in the development process of instruments for the telescope.As Linux systems are being extensively applied in astronomy, it becomes a pressing demand to develop real-time graphical-display systems based on Linux graphical interfaces for astronomical telescopes.In this paper, we present a method that uses a Qt framework to achieve real-time multi-monitor graphical display to meet the requirements for the MUSER ( Mingantu Ultrawide Spectral Radio heliograph, which is originally called the Chinese Spectral Radio Heliograph, or CSRH).We have validated the method through real-time display of cross correlations and auto-correlations of signals detected by the radio antennas of the MUSER.Our experimental results show that our method can meet the requirements of real-time observational monitoring of the MUSER.It has merits such as simplicity, fast response, and excellent portability.The method also overcomes the difficulties of X-WINDOW programming under a LINUX system.Our study can serve as a reference for designs of systems of similar functions on other telescopes.
