|
摘要
由于传感器中定位节点成本相对较高且系统繁杂,易导致节点自我定位功能的误差甚至失效等问题。为了更好地对无线传感网络系统进行设计,以实现高精度定位的系统设计为目标,主要对无线传感网络系统的软件部分进行改进。结合嵌入式节点定位系统进行创新和优化,建立了一种嵌入式无线传感网络控制节点定位系统。从而提高定位系统运行的可靠性、准确性和灵活性,以便使系统能够更好地适用于不同的应用检测定位环境。为验证系统的有效性进行仿真实验,实验结果证明,该方法可有效提高无线传感网络技术定位的精准性和可靠性,有效弥补了传统定位系统中存在的不足,具有更高的参考和实用价值。
The cost of node location in the sensor is relatively high,and the system is complex,which may cause the error or even failure of the node self positioning function. The software of the wireless sensor network is improved to better design the wireless sensor network system and realize the high-precision positioning system design. In combination with the innovation and optimization of the embedded node positioning system,an embedded node location system of wireless sensor network is set up to improve the running reliability,accuracy and flexibility of the positioning system,and make the system more suitable for different application detection and location environments. The simulation experiment was carried out to verify the effectiveness of the system. The experimental results show that the method can effectively improve the positioning accuracy and reliability of wireless sensor network technology,and effectively make up for the shortcomings existing in the traditional positioning system,and has higher reference and practical values.
