介绍了一种用于中小型无人机飞行控制和气动数据采集研究的高频传感器数据采集系统。该系统重量轻，功耗低，工作频率为100 Hz，具有以下特点：高频、高分辨率六自由度（6-DOF）惯性测量单元（IMU），其具有全球定位系统（GPS）接收器、三轴磁力计、皮托管探头、七个10位模数转换器（ADC）、十六个12位模数转换器，一个14位模数转换器、20个数字输入/输出（I/O）、8个脉宽调制（PWM）信号输入、一个40英里下行链路收发器、一个开放式串行和一个开放式CAN总线端口以及高达64 GB的板载存储。数据采集系统完全由商用现货（COTS）组件制造，降低了系统成本和实施时间。SDAC将各种传感器流组合成统一的高保真状态数据流，该数据流被记录用于稍后的空气动力学分析，并同时转发到单独的处理单元，例如自动驾驶仪。
This paper describes a high-frequency sensor data acquisition system (SDAC) for flight control and aerodynamic data collection research on small to mid-sized unmanned aerial vehicles (UAVs). The system is both low weight and low power, operates at 100 Hz and features: a high-frequency, high-resolution six degree-offreedom (6-DOF) inertial measurement unit (IMU) with a global positioning system (GPS) receiver, a 3-axis magnetometer, a pitot probe, seven 10-bit analog-to-digital converters (ADC), sixteen 12-bit analog-to-digital converters, a 14-bit analog-to-digital converter, twenty digital input/outputs (I/O), eight pulse width modulation (PWM) signal inputs, a 40 mile downlink transceiver, an open serial and an open CANbus port, and up to 64 GB of onboard storage. The data acquisition system was completely fabricated from commercial-off-theshelf (COTS) components, which reduced the system cost and implementation time. The SDAC combines the large variety of sensor streams into a unified high-fidelity state data stream that is recorded for later aerodynamics analysis and simultaneously forwarded to a separate processing unit, such as an autopilot.
