使用新一代的非易失性存储器棗铁电随机存取存储器,设计一种能长时间记录变化缓慢的直流信号或监测捕捉记录偶尔出现的脉动信号的可移动数据采集器,是低成本解决现场数据的自动记录的有效办法。文章介绍了几种简单易行的数据记录方法和用Ramtron公司生产的FM24C256存储芯片设计的可移动数据采集器及其记录程序流程,给出了一种可变采样频率记录和脉冲检测记录的综合记录方式数据采集器设计方法。
The use of a new generation of non-volatile memory Zinc ferroelectric random access memory, the design can record a slow change of DC signal for a long time or monitoring capture and recording occasional pulse signal portable data acquisition device is a low-cost solution to the scene An effective way to automatically record data. This paper introduces several simple and easy data recording methods and a portable data collector designed by Ramtron FM24C256 memory chip and its recording program flow, and presents a synthesis of variable sampling frequency recording and pulse detection recording Record data collector design method.
