【摘要】:提出一种高性能的高速数据采集系统,该系统选用采样频率高达65MSPS的模数转换(ADC)芯片,并采用以硬件方式实现控制并行性的现场可编程门阵列(FPGA),避免传统控制器单线程运行难以实现高速采集的瓶颈。详细介绍了数据采集系统的回路构成,并重点论述了FPGA的控制设计。实验测试数据表明文中设计的高速数据采集系统能较好满足小电流接地监测系统的暂态数据分析的需求。
[Abstract]:A high speed data acquisition system with high performance is proposed. The (ADC) chip with sampling frequency up to 65MSPS is used in the system. The field programmable gate array (FPGA), which realizes the control parallelism by hardware, is used to avoid the bottleneck of high speed acquisition in the single thread running of traditional controller. The circuit structure of data acquisition system is introduced in detail, and the control design of FPGA is emphasized. The experimental data show that the high speed data acquisition system designed in this paper can meet the needs of transient data analysis of small current grounding monitoring system.
