【摘要】：传统的光传感网络对易发散、高能耗的热光源信号进行处理时多采用利用麦克斯韦电磁场理论的射线法,该方法对三维场中的信号处理有一定的局限性。针对该问题对传统的电磁场射线法进行优化改进,利用LED冷光源信号替代传统的激光光源,提出了冷光源信号在光纤圆柱形三维场中的微分方程,通过冷光源信号的波矢量k、光线特征参量ν以及传播常数β确定其在光传感网络中的模型,采用多层信号波源叠加的方法,对具有相同频率、相同相位的LED光源进行处理,进而去除掉波源的干涉性、发散性及高能耗的缺点,最终利用Matlab仿真软件可以分析出经过叠加优化处理的冷光源信号在光纤网络中的传递模型,仿真结果证明该方法的有效性。
[Abstract]:The traditional optical sensor network uses the Maxwell electromagnetic field theory to process the easily divergent and high-energy thermal light source signals. This method has some limitations to the signal processing in 3D field. Aiming at this problem, the traditional electromagnetic field ray method is optimized and the LED cold light source signal is used to replace the traditional laser light source. The differential equation of the cold light source signal in the fiber cylindrical three-dimensional field is presented. The model of the cold light source signal in the optical sensor network is determined by the wave vector k of the cold light source signal, the ray characteristic parameter 谓 and the propagation constant 尾. The multi-layer signal source superposition method is used to process the LED light source with the same frequency and the same phase so as to remove the shortcomings of interference divergence and high energy consumption of the wave source. Finally, the transfer model of the cold light source signal in optical fiber network can be analyzed by using Matlab simulation software. The simulation results show that the method is effective.
