摘　　要：介绍了以TMS320F206数字信号处理器(DSP)和嵌入式系统为核心的便携式数据采集分析装置的设计。该装置数据采集模块可实现16路模拟量和8路开关量的同时采集。数据分析模块硬件电路以嵌入式计算机为核心,外围由译码电路、开入/开出电路组成。装置软件包括数据采集和数据分析2部分程序,数据采集程序采用TMS320C2XX标准汇编语言编程,完成数据的采集与上传,给出了程序流程图;数据分析软件采用嵌入式Linux实时多任务操作系统,给出了装置软件程序主界面及各界面功能。所设计的装置运行后,效果良好。A type of portable data sampling and analysis equipment based on DSP（Digital Signal Processor） TMS320F206 and embedded operating system is designed. It can sample 16- channel analog signals and 8- channel binary signals at the same time. The data analysis module takes the embedded computer as its core and the decoding circuit and I/O circuit as its peripheral. The software consists of data sampling and data analysis procedures. Programmed with the assembly language TMS320C2XX,the data sampling procedure samples and uploads data of power system. Its flowchart is presented. The data analysis software is based on embedded Linux real- time operating system. Its main procedural interfaces and their functions are also provided. The designed equipment runs well.
