弹道修正引信外弹道参数存储测试系统设计

Design on In-shell Data Acquisition System of Exterior Trajectory Parameter for Trajectory Correction Fuze

针对中大口径弹丸的弹道参数测试,研制了一种基于C8051F020单片机为控制器的外弹道加速度信号存储系统,针对某榴弹的测试环境要求,进行了软硬件方面的设计,实现了小型化,能够承受高过载和恶劣的发射环境,低功耗。文中主要介绍了存储测试系统的构建,提出了二级存储技术,并能够在系统掉电情况下保持数据的完整性和系统二次上电时的可回读性。

In allusion to parameter test of medium and big caliber shell, acceleration memorizing and testing system of outer trajectory is designed and realized by applying C8051F020 MCU. The system is of small size, capable of working under high impact acceleration and wicked environmental. It has very low power consumption. According to the request of testing environment, the author design the memorizing and testing system including software and hardware , put forward the 2^nd memory scheme. The system can store those data integrality even if the power supply is shut off. When be powered secondly, the data can be read out reliably.
