摘要
针对常规弹药发射环境恶劣、弹体内部空间紧张、传统参数测量方案无法有效工作的问题,提出了一种基于FPGA和微惯性测量单元(MIMU)的飞行参数测量系统的设计方法。该系统通过MIMU测量弹体在飞行过程中的姿态信息,采用FPGA作为控制器来控制模数转换器采集MIMU数据,并将采集到的数字信号以一定格式编码,最终存储到Flash中,实现弹体发射到落地过程中飞行参数的实时记录。仿真实验验证,该系统能完整有效记录弹体飞行全过程中的动态参数,且具有抗高过载、小型化、高可靠性等优点,适合常规弹药的飞行参数的测量,为进一步实现常规弹药制导化提供准确可靠的信息。
Against the fact that conventional ammunitions face the problems of severe launching environment and limited internal space, this paper presents an attitude parameters measurement system based on FPGA and MIMU. By adopting MIMU to measure altitude information of the conventional ammunitions, and FPGA to regulate A/D conversion and data storage in fixed formal, this system can record attitude parameters of the eonventional ammunilions from launching to landing in real time. Flight simulation experiments prove that this system can record the whole attitude infimnation of lhe ammunilions with advantages of high overload resistance, decreased size and high reliaMlity, h can provide accurate dttitude parameters of conventional ammunitions for precision guidance.
