摘　　要：针对国际上VLBI专用硬盘记录终端升级到MK5B后,数据记录格式发生了显著变化,设计了能够适应MK5B数据格式的通道检测软件。MK5B通道检测软件主要用于检查硬盘记录器记录数据的可读性以及确认接收机和VLBI终端等观测设备的参数设定。在软件设计过程中,考虑到软件的可维护性及可移植性,采用面向对象的设计方法。通过对两段观测数据的处理表明,MK5B通道检测软件工作稳定,处理结果正确,能够满足工作需要。The upgrades of the international VLBI special harddisk recording system from MK5A to MK5B causes significant changes of the recorded data format.These changes make an old VLBI channel check software unusable.We design a VLBI channel check software compatible with the MK5B format.Two important purposes of the software are to check the readability and to confirm the parameter settings of the receiver and VLBI data acquisition system.Object-oriented techniques have been used to design the MK5B VLBI Channel Check Software to take into account its maintainability and portability.Experiments of processing two sets of data with the software yield correct results and show that the software can meet practical requirements.
