摘　　要：设计一种采用FPGA的数据采集传输系统。以FPGA为逻辑控制核心,通过RS485接口接收上位机指令,数据传输采用SDLC(同步数据链路控制)协议以提高可靠性。FPGA采集六路AD数据以及八路温度数据,这些数据经由DSP处理之后存储至FLASH中。FPGA根据上位机指令,读取FLASH中相应的数据并通过RS485接口上传至上位机。经系统测试验证,该设计能够满足技术要求,数据的采集、存储、传输均正确,为后续工作提供了保障。A data acquisition and transmission system based on FPGA is designed.FPGA is used as the logic control core,and RS485 interface is used to receive instructions from upper computer.SDLC(synchronous data link control)protocol is used for data transmission to improve reliability.FPGA collects six channels of AD data and eight channels of temperature data,which are processed by DSP and stored in FLASH.According to the instructions of the upper computer,FPGA reads the corresponding data in FLASH and uploads it to the upper computer through RS485 interface.It is verified by the system test that the design can meet the technical requirements,and the acquisition,storage and transmission of the data are correct,which provides a guarantee for the follow-up work.
