摘　　要：为了方便外场电机测量及维护工作,提出了一种基于片上可编程系统(SOPC)技术的便携式低成本数字示波器设计方案。与传统FPGA作为数据存取处理MCU作为显示控制的设计方案不同,基于SOPC的便携式数字示波器设计方案通过在FPGA中嵌入Nios II系统,作为CPU实现对LCD波形及参数显示控制;利用FPGA的逻辑资源,设计采样数据的存取控制模块,实现采样信号的触发存取功能。系统测试结果表明本文所设计的系统具有设计简单、低成本、稳定性好,可重复开发等特点。To facilitate the external measurements and maintenance tasks,proposed an implementation of portable digital storage oscilloscope system,based on programmable chip(system on programmable chip)technology.Unlike the traditional design of FPGA for date access process and MCU for display control,the design of portable digital oscilloscope based on SOPC embeded Nios II into FPGA.The embedded system acted as a CPU which controls display of LCD waveform and parameters.In addition,FPGA logical resources were used to design access control module of sampling data and realize trigger access function of that.System test results show that the designed system has the characteristics of simple design,low-cost,good stability and repeatable development.
