摘　　要：针对静态存储器掉电数据易丢失的缺点,提出了一种基于复杂可编程逻辑器件(CPLD)和闪存的弹载测试系统。该控制系统充分利用CPLD功能,采用VHDL语言和图形化编程方式,有效地实现了对A/D、静态存储器及闪存的时序控制,实现了对弹体飞行姿态(三轴加速度、三轴角速度及两路地)的分时采样、存储及数据的显示。Aimed at solve the problem of data lost when SRAM is powered down, a new bullets measurement system based on CPLD and flash storage is presented. The control system can achieve the operation on the A/D converter,SRAM and flash storage effectively by using CPLD sufficiently, the language of VHDL and graphic editor. The time-sharing data acquisition, storage and display for the attitude of bullets in flight is realized.
