Abstract: Traditional experiments of free-flight in the wind tunnel use scale models to study aerodynamic parameters, with the increase in the type and number of collectors, the design of airborne equipment structure and control of data transmission are becoming more and more difficult. Aiming at this current status, a multi-channel data acquisition and transmission system based on 乐通lt009老虎机网页 logic control and timing drive is designed. The system adopts the three-terminal structure of airborne terminal, ground terminal and upper machine terminal, and the division of labor is clear. The airborne terminal adopts a miniaturized two-layer structured design to acquire the angle signal, wind direction sign signal, Inertial Measurement Unit (IMU) signal, aviation attitude signal, the ground terminal is responsible for the integration and distribution of data, and the upper computer terminal performs data monitoring and system control. After testing, the acquisition resolution of the system is ±0.07%FS(Full Scale) and a data transmission cycle is less than 2.42 ms, which is in line with the expected target.
