摘要
网络化虚拟仪器的使用可以大大提高通信测试设备的利用率,增加通信测试的灵活性。通过分析和比较各种虚拟仪器及网络化虚拟仪器系统的组建模式的特点,结合某卫星测控站现有通信测试系统的实际结构,选择基于HPVEE和三层C/S网络的虚拟仪器作为构建网络化虚拟仪器通信测试系统的基础,对系统网络软硬件进行设计,实现基于网络化虚拟仪器通信测试系统,完成该测控站从单一的通信测试操作单位向通信测试平台和通信测试软件研发中心的转变,并可为类似需求提供有效的技术支持。
The use of networked virtual instrument can greatly improve the communication test equipment utilization, and increase the flexibility of the communication test. After comparing kinds of virtue instruments, analyzing the character of the networked virtue instrument systems, and considering the situation of a communication test station, HPVEE and C/S structure were chosen to be the basement of a communication test system for design. The layers of the system were defined. And the data flow of system was planned. Finally the instrument and the hardware of the system were designed. The system can do the communication test through the intranet in different thread. It implemented the instruments share on the intranet by time difference.
