| Abstract: | 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. |
