本文基于组合导航接收机的研制背景,对在VB环境中开发上位机软件进行了详细的说明,其中包括上位机与下位机之间的数据通信、数据的实时显示、操控指令的生成、用户界面的设计等等。其后,通过与下位机连接,运行组合导航接收机程序验证了上位机软件开发的正确性、实用性、直观性。 In this paper, based on the research background of the integrated navigation receiver, a detailed description of the PC software development in the VB environment, including data communication between the host computer and the next crew, real-time display of data, the generation of manipulation instructions, user interface Design and so on. Later, through the connection with the lower computer, running the integrated navigation receiver program verified the correctness, practicability and intuition of the software development of the upper computer.
