摘要
本文介绍一种新型数据采集系统。系统采用新一代快闪存储芯片，实现了低价位、高容量、掉电自保护的数据存储，使用快速12位模拟转换器，提高了采样精度，利用单片机实时控制，并对其地址总线进行了扩展，采用并行通信与计算机进行数据传输，提高了传输速度与准确性。本系统在应用中获得良好效果。
This paper presents a new data collector in which a new kind of super-flash ram is used to achieve a data recorder with low price,high volume and non-volatile data recorder. The high precise data can be obtained from a 12 bits A/D converter. A singlechip mlcrocomputer will control the system in time with its address bus extended for large data space. For high reliability and faster data communication with personal computer,the parallel communication technology is applied. The system is good in practical results.
