Development of High-Speed Data Acquisition System for Small Current Grounding System Fault Detection
High-speed,accurate analog-digital conversion module is the difficulty in achieving small current grounding system fault detection based on transient data analysis.This paper presents a high-performance data acquisition system,which selects a kind of A/D chip with sample frequency up to 65MSPS,uses FPGA to achieve control parallelism in hardware way to avoid the problem of single-threaded running in the traditional controller such as MCU,and introduces the circuit construction of data acquisition system in detail,then focuses on the FPGA control design.Experimental data shows that the designed system fully meets the needs of transient data analysis of small current grounding fault detection system.
