基于MSRAM的微型化采集存储系统设计

Design Of Miniaturized Acquisition And Storage CircuitBased On Serial MSRAM

摘要:

针对条件恶劣、空间受限的飞行目标测试环境中对其数据采集存储系统的低功耗和微型化的要求,本文提出了一种采用MSRAM作为数据的主要存储介质,结合FPGA芯片AGL030作为主控制部分的微型化数据采集存储方案。并对电路的采集存储、节能、延时进行了软件设计,对相关功能的实现进行了仿真,调试后采集存储电路工作稳定,采集存储数据回读拟合波形完整。该采集存储系统最终被成功应用于某型号的飞行炮弹数据记录中。

Abstract:

In the limited conditions, space flight target test environment, it"s necessary that realize the miniature data acquisition and storage circuit. This paper presents a miniature data acquisition and storage circuit that use FPGA chip AGL030 as the control chip and serial MSRAM chip MR25H40 as data storage medium, and the circuit software design of the data acquisition and storage, energy saving, time delay. And has carried on the simulation to the implementation of related functions; Collection and storage circuit stable work after debugging, the read back fitting waveform of collection and storage data is complete. The collection and storage system was successfully applied to a type of flying projectile data record.
