针对在弹体飞行姿态测量实时处理分析过程中,采用FPGA和单片机的半硬回收方式存在结构复杂、体积较大、运算能力差的问题,文中从弹体处于高速、高过载的环境出发,设计了基于TMS320F28335由传感器、ADC、DSP以及存储芯片组成的弹体飞行参量采集硬回收系统,实现弹体动态信息的采集、处理和存储。实验证明,系统能够完整精确的获取弹体飞行姿态测试过程中的各种参量,能够为弹体飞行参量测试提供有力依据。

For projectile flight attitude measurement, the problems with real-time processing and analysis processing, the half hard-recovery of FPGA and microcontroller are complex structure, larger volume and poor operation. As for the projectile at high speed and under high overload environment, a projectile flight parameter acquisition and hard recovery system was designed based on TMS320F28335 and composed of sensors, ADC, DSP chip and memory chip so as to achieve projectile dynamic information acquisition, processing and storage. The test shows the system can completely and accurately obtain various parameters in the projectile flight parameter test process. The system can provide a strong basis for the projectile flight parameter test.
