Design And Implementation Of Measurement System Of Aircraft Electromechanical Equipment Based On PXI Bus

As the most important aircraft electromechanical equipment at present and the core of the Electromechanical system, electromechanical management system is responsible for the comprehensive monitoring, control and management of other electromechanical system. Except for the advantage of high degree of integration, strong fault tolerance and so on, the characteristics of electromechanical management system, such as its large number of electromechanical system, large signal quantity and complex logic relationship, have greatly increased the difficulty of its design and implementation. From the functional analysis of the electromechanical system, completed the overall system design, hardware design, system integration, software design, based on PXI bus, a measurement system of aircraft electromechanical equipment is designed to construct a simulation test environment for the electromechanical management system. The measurement system simulates the I/O interface, working logic, alarm information and receives control commands issued by the electromechanical management system for verifying that the electromechanical management system for the electromechanical system control and management are correct. The system is a good solution to the above problems, a large number of the system debugging and test shows that the system is stable and reliable, can meet the needs of the test tasks, and then complete the functional verification of the electromechanical management system. It can be applied to electromechanical management system loading machine test and flight test during machine fault in laboratory reappearance and analysis. It plays an important role in ensuring the aircraft first flight, transition and follow-up test.
