基于ARM的高精度数据采集系统设计

摘要

针对传统数据采集系统结构复杂,体积大,成本高的问题,设计了一种基于ARM的新型、低成本、高精度数据采集系统,并提出了该系统的设计方案.详细论述了数据采集系统的硬件实现方案、抗干扰措施及控制时序,重点分析了高精度并行A/D的工作时序.实际应用结果表明,该数据采集系统精度高,体积小,成本低,工作性能强,具有较高的实用价值和借鉴意义.%For the problems of structure complexity, big volume and high cost of traditional data acquisition systems, a low-cost and high-accuracy data acquisition system based on ARM was designed. The design scheme of the system is given. The hardware implementation scheme, anti-interference measures and control time sequence of data acquisition system are elaborated. The working time sequence of high accuracy parallel A/D is analyzed emphatically. The practical application shows that the system has the characteristics of high accuracy, small size, low cost and strong working ability, and has a high pragmatic value and a reference for the design of similar systems.
