Design of Data Acquisition and Processing System of Simulated Aircraft Hatch Based on RS422 Serial Bus

摘要

Simulated aircraft hatch is an important part of flight simulator, which provides a completely the same training environment as real flight. The paper constructs data acquisition and processing system of aircraft hatch based on RS422 bus composed of instrument computer, data acquisition computer and interface control, and gives examples that are data acquisition of device control and measuring control of weapon system to illustrate design scheme of our system. The application result indicates that the system runs stably and credibly, the system gathers and processes data accurately, and has satisfied real-time character.
