基于ARM的高速高精度数据采集系统设计ARM，S3C44B0XAD7663 The Design of High speed and High precision Data Acquisition System Based on ARM ABSTRACT In recent years, with computer technology, electronic technology and technology development, how to collect and process the data becomes more important. The speed and accuracy of data collection are the two main directions of the data acquisition system. MCU, ARM, DSP and other microprocessors are widely used provides an effective platform for data acquisition system. High speed and high precision signal acquisition as well as the research and design of collected data is the main task of this project. Based on the ARM7S3C44B0X this paper introduces the design and implement of a high speed，high accuracy，multiple channel data acquisition system. Using rich function interface and higher operating frequency of S3C44B0X achieves signal acquisition and data processing functions. This article describes the research status and development trend of the data acquisition system, selects the main chips of the system and the AD7663 analog digital converter. According to the modular idea, the system is divided several functional units and analyzes each functional module and provides a schematic diagram and general diagram .Some point of view to the design of the high accuracy data acquisition system was put forward at the end of this article. The system has low cost, low power consumption, recognition performance is strong and intelligent degree in higher advantages, which has relatively broad application prospects.
