摘要
针对目前传统示波器体积较大、不易于携带且无法远程观测信号的问题,提出了一种蓝牙便携式示波器数据处理端设计方案。其采用STM32F4微控制器作为主控核心,实现了波形的采集、处理及相关参数的计算;运用Android手机应用软件(APP)作为显示界面,以控制信号通信的方式建立与APP显示界面相对应的水平时基分辨率、垂直电压分辨率及位置分辨率数学函数关系。信号波形显示和存储的结果以及参数的计算数据表明,该数据处理端设计方案是可行的。
In view of the problem that the traditional oscilloscope has a large volume,is inconvenient to carry and cannot remotely observe the signal,a design scheme of data processing part with the Bluetooth portable oscilloscope is proposed. It uses STM32 F4 microcontroller as the main control core,and realizes the waveform acquisition,processing and calculation of related parameters. It utilizes Android mobile phone application（ APP） as the display interface. The mathematical relationship between the communication control signal and the horizontal time base resolution,vertical voltage resolution and position resolution corresponding to the APP display interface is established. The results of signal waveform display,storage and the calculation of waveform parameters show that the design scheme of the data processing part is feasible.
