基于AD7616的16通道数据采集系统设计
AD7616-Based 16-Channel Data Acquisition System Design
摘要
Abstract
A multi-channel data acquisition system based on AD7616 is designed to address the problem that traditional data acquisition systems cannot meet the simultaneous acquisition of 16-channel data due to insufficient channels or excessive data volume.The system uses Xilinx series FPGA as the main control chip.The AD7616 from ADI is used as the analog-to-digital conversion chip.The DDR3 SDRAM is used as the cache unit.The article first introduces the design idea of each module hardware,then focuses on the software program design of the FPGA control AD7616 analog-to-digital conversion module,DDR3 SDRAM cache module.And the system's multi-channel sampling function,synchronization performance and the actual underwater ultrasonic signal acquisition capability are experimentally verified,and the results show that the system can complete the multi-channel synchronization acquisition of underwater ultrasonic signals.关键词
