针对目前卫星地面站链路测试系统测试流程固化的问题,采用了虚拟机的思想,设计了一个执行测试指令的指令机,基于该指令机,实现了一种可编程的链路测试系统；该系统为不同的链路测试建立了一个统一的测试框架,简化了软件系统的结构；同时,该系统定义了自己的测试脚本格式,极大地增强了测试系统的可编程性和可扩展性；实际应用中编写了14种链路测试脚本,形成通用测试库,基于该库顺利完成了该站的链路指标测试工作,系统运行稳定,测试数据准确可靠；通过修改脚本,可以方便地设计新的测试流程,大大提高了测试的可扩充性和测试效率,具有一定的实用性和推广价值.%With the idea of virtual machine, this paper develops a instruction machine which can execute measurement instruction. Based on this instruction machine, the paper implements a programmable TTC link measurement system to solve the problem that current TTC link measurement system is immutable in measurement flow. This system builds a uniform measurement frame for various TTC link measurements and simplifies the software structure. Also, the system defines the own format of measurement script, which greatly enhances the pro-grammability and expansibility of the measurement system. In the actual application, we write 14 measurements scripts and forms the common measurements library. Based on the library, we successfully finish the measurement work, the system can run stably, and the data of result is accurate. By modifying the script, we can easily design a new measurement flow, greatly improved the expansibility and efficiency of measurement, so the technology and methods adopted in the system are practical and worthy of using abroad.
