本文设计了数据采集存储系统,阐述了数据记录器中各部分电路硬件设计。系统采用可编程逻辑器件FPGA来实现整个系统的逻辑控制以便同时可靠的采集、存储多路模拟量和数字量数据,以FLASH为存储介质,对存储模块进行最小化设计,大大缩减了系统的体积,延长了数据的保存时间,进一步提高了系统的可靠性。 In this paper, a data acquisition and storage system is designed, and the hardware design of each part of the data logger is described. The system uses programmable logic device FPGA to achieve the entire system of logic control in order to reliably collect and store multiple analog and digital data at the same time to FLASH as storage media, storage modules to minimize the design, greatly reducing the size of the system , To extend the data retention time, to further improve the reliability of the system.
