近距离无线通信的嵌入式数据记录设备设计

Embedded Data Recording Device Based on Close Range Wireless Communication

根据某工业现场电子设备数据记录的要求,设计了一种基于近距离无线通信的嵌入式数据记录系统。该系统分为数据存储和数据下载两大功能组成部分:数据存储部分利用DSP和FPGA完成信号的采集和处理,并将其存储到CF卡中;数据下载部分利用红外和蓝牙无线接口,在DSP的控制下实现数据的无线下载。

According to the requirement of data recording on industrial electronic equipment,an embedded data recording system is designed based on close range wireless communication.The system is divided into two main functional component parts：data storage and data download.In the data storage part,signal collection and management are implemented using DSP and FPGA,and data is stored into the CF card.In the data download part,with infrared and Bluetooth interfaces,data download is achieved by the control of DSP.
