摘要
便携式数据采集仪表可灵活方便地实现数据采集任务 ,减少计算机的硬件资源 ,尤其适用于野外的数据采集。该仪表从设计上可分为单片机部分和PC机部分 ,单片机部分是以 89C5 1为核心 ,结合A/D转换、时钟、电平转换和存储器等外围芯片 ,实现了数据采集和存储的任务 ;
Portable instrument for data collection is used for its convenience and flexibility. The using of it can reduce the hardware resource of PC. Especially used for outdoors. The design of this instrument is divided into two parts:sigle chip microcomputer and PC.Data collection is implemented by sigle chip microcomputer.AT89C51 is the hardcore of this part which have other peripheral chips such as A/D converter,calendric clock,voltage converter and memory.Data analysis is realized by the software of PC.
