本文研究了一种定容量循环存储方法来实现对引信电池工作时电压及噪声的监控。针对有限的存储空间,采用负延迟触发的方法对每片Flash设计了4 MB的循环采样空间来记录触发前4 MB的数据,并实现触发后顺序记录50 MB的数据;采用两片Flash交替工作的方式,避免了命令传送与数据编程在时间上的冲突。该方法合理地利用了存储空间,有效地记录触发前的信息,保证了数据的可靠性和正确性。实验测试表明:该系统可实现对引信电池的监测。
This paper studies a constant-capacity cycle storage method to monitor the voltage and noise of fuze battery. For the limited storage space, the method of negative delay triggering is used to design a 4 MB loop sampling space for each Flash to record 4 MB of data before triggering, and to sequentially record 50 MB of data after the trigger. The two Flash alternately work The way to avoid the command transmission and data programming in time conflict. The method makes reasonable use of the storage space and effectively records the pre-trigger information to ensure the reliability and correctness of the data. Experimental tests show that: The system can be fuze battery monitoring.
