摘要
对信号的准确观测是研究信号的重要手段和首要前提,而逐渐多样化的户外信号研究更是让人们渴望拥有一款能够具有太阳能充电功能的便携信号观测仪器。初步探索了一种具有太阳能功能的便携示波器,系统采用ARM-Cortex M7架构的高性能处理器,配以相关信号调理电路,最终在TFT彩色液晶显示器上实时动态显示。系统以STM32微处理器为控制核心,以较低成本实现了信号采集、显示、频谱分析等功能。
The accurate observation of the signal is an important means and the first premise of the study of the signal,and the gradually diversified outdoor research makes people eager to have a portable signal observation instrument with solar charging function.In this paper,a portable oscilloscope with solar energy function is preliminarily explored.This system adopts a high performance processor with arm cortex M7 architecture,and couples with related signal conditioning circuit,finally displays on the TFT high color LCD in real time.With STM32 microprocessor as the control core,the system realizes signal acquisition,display,spectrum analysis and other functions at a lower cost.
