摘　　要：新的重装空投数据采集分析系统选用高集成度Cortex-M3处理器为主控芯片,对重力加速度、三轴角速度及应变力数据进行采集,采集的数据实时保存到Flash存储器.采集结束后,PC端数据采集分析系统通过串口读取数据采集器中的数据,经过数据揉合与处理分析,图形化显示重装空投过程中物体的重力加速度、三轴姿态、应力形变等变化过程.系统将数据采集设备和数据处理设备进行分离,实现了利用相对低硬件成本获取较高精确度和实时数据的采集.现场实验测试证明,该系统方案具有较高的精确度和实时性,可广泛用于空投高速实时数据采集领域.A novel heavy cargo airdrop acquisition and analytic system was implemented. The main control chip is a highly integrated Cortex-M3 Processor. The data of gravitational acceleration, triaxial angular velocity and strain were collected in real-time and stored in Flash memory. After the acquisition, PC terminal analyzed these data through the serial port. The changes of gravitational acceleration, triaxial angular velocity and strain during landing were displayed in graphic. In this system, data acquisition equipment and data processing equipment were separated to obtain high accuracy and real-time data acquisition. Field experiment proves that this system shows higher accurate and real-time performance.
