基于FPGA的无线传感器设计

Design of the FPGA-Based Wireless Sensor

现代技术可以用飞机或远程火力布撒传感器网络节点到敌方战场,用以详尽准确地探测目标战场的精确信息。针对这一数据采集传感器网络节点具体应用,运用FPGA器件Cyclone芯片实现对控制A/D转换芯片AD1674的采样控制,利用QuartusⅡ开发平台进行软件编程实现了对的A/D转换芯片的工作时序控制,节点平台用FPGA实现MAC逻辑控制和相关帧数据处理,对模拟采样数据组帧编码,利用射频芯片实现无线链路向外传输。

In modern technologies, the wireless sensor network nodes can be dispensed to the enemy battlefield by using aircraft or remote firepower so that they can accurately detect the detailed information on the target battlefield. For the specific applications of this data collection system, a FPGA Cyclone chip is used to control the A/D conversion chip AD1674 to perform data sampling control, on the Quartus II framed and coded to send out through the radio link.
