摘　　要：针对机车信号抗干扰测试效率低和误差大等缺点,采用仪器领域中先进的VXI总线技术,基于LabWin dows/CVI的虚拟仪器开发环境,研制了机车信号抗干扰自动测试系统。研究中,应用了状态转移分析法和黄金分割的优化算法。结果表明:由于应用了VXI总线技术,使得测试的效率和质量都得到了大幅度的提高。本文分析了系统的硬件结构、软件结构和抗干扰自动测试的原理。In view of the low efficiency and high error of cab signal anti-interference tests, a kind of cab signal anti-interference automatic test system is developed. It is based on the virtual instrument development environment of LabWindows/CVI and uses the VXIbus technology which is advanced in the field of instruments. The state-shifting analytical method and optimized golden section are algorithm emploped in. The conclusion shows that the test efficiency and quality are well improved by using the VXIbus technology. The hardware architecture, software architecture and anti-interference auto-test principle of the system are also discussed in the paper.
