摘要
介绍了一种基于ARM的烟气分析仪测控系统的实现方案,包括硬件平台的构建和系统软件的设计。系统硬件以AT91RM9200为核心,负责整个系统的控制和数据处理,由FPGA完成系统多路数据采集的控制,并与AT91RM9200通过EBI总线传输数据。以嵌入式Linux操作系统为软件平台,使用图形化编程语言Qt完成应用程序的设计,实现了人机交互、数据采集、数据分析与存储等功能。该测控系统满足了烟气分析仪对多种物理量信号采集分析的需求,具有高性能、低成本的优点。
This paper introduces the realization program of a kind of Flue Gas Analyzer based on ARM, which contains the construction of hardware platform and the design of software. This system makes AT91RM9200 as its nuclear, controls the whole system and data processing, uses FPGA to control the multi - channel data acquisition and transfers data with AT91RM9200 via EBI bus. With embedded Linux OS as its software platform, the system uses graphical programming language Qt to finish the design of applicatian process, realizing the hunman - com- puter interface, data acquisition, analysing, storage, etc.This system can meet the requirement of the flue gas analyzer that collects and analyses a variety of physical signal, with advantage of high - quality and low - cost.
