| 摘 要： | 提出了一种以STM32微处理器为控制核心,ADS8365作为采集芯片,NAND Flash K9K8G08U0M作为存储芯片的采集存储系统。该系统在"点火"信号下被唤醒并开始工作,具有很低的功耗,同时增加断电保护机制,保证该系统在外部系统供电失效的情况下仍能够正常工作。重点介绍了STM32与ADS8365的硬件电路设计、断电保护电路设计和STM32的FSMC操作Flash的软件设计。测试表明,该系统可靠稳定,能够在恶劣飞行条件下工作,满足任务要求。

| Abstract: | A signal acquisition and storage system with the STM32 microprocessor as control core, ADS8365 as acquisition chip, NAND Flash K9K8G08U0M as memory chip is proposed. The system is awakened to work under "fire" signal with very low power consumption, while the power protection mechanism to ensure that the system in case of failure of the external power supply system is still able to work properly is added. The hardware design of the STM32 and ADS8365, the power protection circuit design and the software design on the STM32 how to operate FSMC Flash are focused on. Test results show that the system is reliable and stable, able to work under harsh flight conditions, to meet mission requirements. |
