摘　　要：为了实现加速度传感器批量标定测试,能让16个加速度传感器同时并行测试,设计了基于FPGA和以太网的多通道数据采集系统。该系统以FPGA为核心控制芯片,实现16路模拟信号的实时采集、编帧与数据存储,并通过以太网接口芯片W5300完成与上位机的通信。整个系统采用模块化设计,功耗低、采集精度及可靠性高、实时性好,已成功应用于加速度传感器批量标定测试设备中。In order to realize the acceleration sensor calibration test and to make 16 acceleration sensors realize test in parallel,a multi-channel data acquisition system has been designed based on FPGA and Ethernet. This system takes the FPGA as the core control chip,which implements the real-time,frame and data storage for the 16 road ana-log signals,and through the Ethernet interface the chip W5300 completes communication with PC. The whole system uses modular design,to get low power consumption,high acquisition precision and reliability,and good real-time performance. What is more,it has successfully applied in the equipment of accelerometer mass calibration test.
