基于LabWindows/CVI的近地告警测试系统设计

针对当前传统自动测试系统本身模块化水平低、技术升级困难的特点,提出用虚拟仪器技术开发测试系统的方法.并给出了基于LabWindows/CVI软件开发平台的近地告警测试系统的具体实现.着重从系统硬件架构和软件系统两方面介绍了用虚拟仪器实现进地告警测试系统的设计实现.采用将测试资源划分为公用测试资源和专用测试资源的方法,成功实现了测试系统的高模块化;并利用LabWindows/CVI的强大通讯功能实现了系统实时在线测试功能.通过实际测试和评估,该近地告警测试系统运行良好,证明该设计方法十分有效.

Design of ATS Based on LabWindows/CVI for GPWS

The method of design of ATS baaed on virtual instrument technology is presented against the poor modularization and difficulty of upgrading thetechnology of the existing system. By reviewing thc characters of the virtual instrument technology, the method of u- sing the virtual instrument technologies to design the ATS is brought forward. The design of the ATS based on LabWindows/CVI for GPWS is also stressed. And a way to realize the ATS based on virtual instrument technologies from the hardware structure and software system is also showed. The high modularizatlon of the system is realized by means of dividing the test sources into general test sources and special test sources, and the capability of test on line is also realized with the help of great communication function of the LahWindows/CVI. In result this method is proved effective after evaluation.
