针对在恶劣或危险的环境中大范围区域性参数测量和数据中继传输困难的问题，提出了一种基于现场可编程门阵列(FPGA)和无线传感器网络节点的数据无线传输方法。该方法采用 FPGA和无线传感器组成单个无线传感器网络节点，并在此基础上，通过利用 ACK收发应答机制和无线收发芯片多通道传输特性，将各个无线传感器网络节点通过层次路由协议进行数据组网传输。实验测试结果表明无线传感器网络节点的通信性能良好，数据传输速率高、传输时延较小；路由协议不仅能保证节点间全局组网，而且数据传输的稳定性好，能够适用于大多数测试场合。

Wireless data transmission system based on FPGA and wireless sensor node was put forward to solve large scale parameter measure in danger environment.The wireless sensor node adopted FPGA and wireless sen-sor as its transceiver and micro-control unit,and transmitted data through hierarchical routing protocol by use of the function of transponder and multi-channel characteristic.The measurement results showed that the method had high transmission speed and low time delay,and the net worked stably to perform reliable wireless data transmission.
