摘要:
针对示波器普遍体积大、不易携带以及价格昂贵等问题,提出了一种基于 FPGA 和 STM32 相结合的便携式数字示波器设计方案。 系统主要由前端信号调理电路、触发电路、数据采集和存储和波形显示等模块构成,前端采用的是高性能、用来实现高速数据采集、存储与传输的低功耗芯片 FPGA;系统主控制器部分采用 ARM 系列的 STM32F103 芯片,用来进一步处理和控制波形的重建、显示以及存储。 主控制器的软件系统主要由 μc OS II 操作系统和嵌入式图形用户界面 μc GUI 组成,充分保证了整个系统的稳定性和实时性。 整个设计实现了存储示波器的所有功能要求,并增加一些实用的功能。 信号波形显示和存储的结果以及参数的设计表明,该系统不仅成本低、方便携带,而且具有较高的性能指标,保证了系统在复杂环境下处理信号的效率。
Abstract:
A design scheme of portable digital oscilloscope based on the combination of FPGA and STM32 is proposed to solve the problem that the oscilloscope is generally bulky,difficult to carry and expensive. The system is mainly composed of front-end signal conditioning circuit,trigger circuit, data acquisition and storage, waveform display and other modules. The front - end adopts high-performance FPGA,a low-power chip used to realize high-speed data acquisition,storage and transmission. The main controller part of the system adopts the STM32F103 chip of ARM series to further process and control the reconstruction,display and storage of waveform. The software system of the main controller is mainly composed of μc OS II and μc GUI,which fully guarantees the stability and real-time performance of the whole system. The whole design implements all the functional requirements of the storage oscilloscope,and adds some practical functions. The results of signal waveform display and storage,as well as the design of the parameters indicate that the system is not only low cost and convenient to carry,but also has a high performance index,which ensures the efficiency of signal processing in complex environment.
