对Mark5B监控系统软件的设计思想、软件功能、通讯机制等几个方面作了介绍。Mark5B记录系统是当今世界VLBI观测台站中广泛使用的最为先进的记录系统之一,也是VLBI终端系统的重要组成部分。研制Mark5B监控系统软件的主要目的是进一步提高VLBI终端记录系统的可靠性,保障VLBI联测数据有效和高质量。该软件是在Qt开发环境下采用signals/slots的安全类型机制,并在Qt creator IDE上设计图形界面,完成数据采集和网络通信工作。Mark5B监控系统不仅适用于VLBI天体物理测量观测、VLBI测地观测,而且适用于中国VLBI网(The Chinese VLBI Network,CVN)联测。

In this paper we mainly discuss the design ideas，functions，communication mechanisms，and related issues of the software of a Mark5B monitoring system，which incorporates a Mark5B recording system．Mark5B recording systems are currently widely used in astronomical observation stations around the world．Mark5B recording systems are among the most advanced terminal recording systems，A Mark5B recording system is an important part of a VLBI terminal system． Our main purpose of developing the software of a Mark5B monitoring system is to improve the reliability of a VLBI terminal system，i. e． to ensure the effectiveness and high quality of VLBI measurement data． The software is designed under the Qt-based development environment and uses the signals /slots as a secure communication mechanism． The graphical interfaces of the software were designed in the Qt Creator IDE． The data collections and network communications of the software are realized in the Qt Creator IDE as well． The Mark5B monitoring system with the software is suitable not only for astrophysical observations but also for VLBI geodetic surveys． The software will be used in the Chinese VLBI Network stations other than the Xinjiang Astronomical Observatory．
