【摘要】:无线传感器网络(WSN)节点无法连入网络主要原因是硬件故障和阴影衰落效应,为解决这个问题,文中设计制作了故障节点检测仪。利用液晶显示器LCD1602作为人机交互界面,通过4×4矩阵键盘输入指令,控制无线通信模块nRF905检查网络信息。通过对比检测仪对网关节点和传感器节点的检测数据,能够判断出节点无法接入网络的原因。实验结果表明,该检测仪能够判断WSN中由于硬故障和阴影效应而无法连入网络的故障节点,为调整WSN节点配置提供参考,从而提高网络的连通性。
[Abstract]:In order to solve this problem, the main reason why (WSN) nodes in wireless sensor networks can not connect to the network is hardware fault and shadow fading effect. In order to solve this problem, a fault node detector is designed and manufactured in this paper. The liquid crystal display (LCD1602) is used as the man-machine interface, and the 4 脳 4 matrix keyboard is used to input instructions to control the wireless communication module (nRF905) to check the network information. By comparing the detection data of the gateway node and the sensor node, the reason why the node can not access the network can be determined. The experimental results show that the instrument can judge the fault nodes in WSN which can not be connected to the network due to hard faults and shadow effects, and provides a reference for adjusting the configuration of WSN nodes, thus improving the connectivity of the network.
