摘要
为了实现模拟数据的多通道实时采集,提出一种高集成度的多通道数据采集系统设计方法。该系统设计选择新型FPGA芯片MAX10作为主控制器,该芯片主要集成了模数转换器(ADC)和双配置闪存,采用Altera公司的开发工具Quartus II 14.0,设计了相应的AD数据采集模块、用户闪存读取控制模块以及LCD显示控制模块,并详细论述了各模块的工作流程,给出了MAX10中ADC配置,其中包括模数转换ADC IP内核及锁相环PLL IP内核的配置过程,最终实现了多通道数据采集的实时采集及显示。实验测试结果表明,对于输入的模拟电压信号,LCD显示的数据采集结果具有很高的测量精度,满足电压数据采集的要求。
To meet the requirements of multi- channel real time analog data acquisition,a highly integrated multi- channel data acquisition system design method is proposed. A new FPGA chip,MAX10,used as the main controller,integrates ADC and dual configuration flash and employs the development tool of Quartus II 14. 0 from Altera company. AD data acquisition module,user flash memory read control module and LCD display control module are designed,and the workflows of each module are discussed in detail. Then the configuration of MAX10 ADC,including the implementation process of ADC IP core and PLL IP core,is given to achieve real time acquisition and display of multi- channel data acquisition. The experiment result shows that,for analog voltage signal inputs,the data collection results displayed by LCD have high accuracy and meet the requirements of voltage data collection.
