资料介绍

针对无线地下传感器网WUSN(Wireless Underground Sensor Network)中的信道高路径损耗、信道条件动态变化大和天线尺寸过大等问题,提出一种基于磁感应技术的WUSN收发节点的硬件设计方案。设计了通信系统节点的硬件结构,以及包括天线发射电路、接收电路、程控放大电路和高速A/D采样电路的收发器外围电路,搭建了收发通信和性能测试平台。实验结果表明:经FIR滤波器和希尔伯特检波后低频干扰被滤除,降低了误包率,硬件节点满足要求,验证了设计的可行性和可靠性。

For Wireless Underground Sensor Networks(WUSN)high loss of the channel of its antenna path,the change of dynamic channel conditions is obvious great,and its too large,a hardware design scheme based on magnetic induction technology of WUSN transceiver is selection of a communication system node hardware structure and the main controller and the coil are designed and included an antenna transmitting circuit,receiving circuit,programmable amplifier circuit and high speed A/D sampling circuit of transceiver peripheral circuit,and the related key parameters for the design of performance indicators are transceiver performance test platform is set up and then the changes of the osc...
