Design of CTS Measurement & Control System Based on the VXI Bus

The Capture Trajectory System (CTS) is an advanced measurement method of the trajectory for store separation in wind tunnel test. According to the characteristics of good real-time, high reliability and a large amount of data processing in the CTS test, an open-architecture measurement & control system based on VXI bus and PMAC2 is proposed in this paper, and its overall scheme design, hardware composition and software structure are described. With IPC, embedded operator and PMAC2 applied, the three level microcomputer structure ensures the system has good real-time and accurate trajectory control. The hierarchical software and the modular design method make sure that the system has good portability, universality and extensibility.

Analysis of Airplane Timing Equipment’s Automatic Test Based on ATS Platform

Test airplane timing equipment automatically is usually difficult because of great working current and strong electromagnetic interference . This article analyzed automatic test on airplane timing equipment based on ATS platform that uses digital I/O module and VXI bus, which can reduce the impact of the device operating current on the system. Moreover, the method can execute parallel test on several working hours at a time.

A Novel Method for the Design of Digital System Fault Diagnosis Instrument Based on VXI Bus

To meet the requirements of the testing for modern complex digital systems and devices, A novel method for the design of digital system fault diagnosis instrument based on VXI bus is described in this paper, and the composition and design principle of the hardware of the presented method is introduced in the paper. The instrument designed with the novel method provides 64 pins of Transistor-Transistor Logic (TTL) digital I/O for the test of digital modules and systems. Testing can be automatic accomplished by programming a sequence of test vectors. Real-time data comparison ensures fast test execution by eliminating the post processing of test data. Branching and test execution pause enhance the ability to synchronize the test system to activity of the unit under test (UUT). The experimental results show the module designed with the presented method has much more higher performance than the only similar manufacture VX4820.
