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。The light of the traditional sensor networks on prone, high energy consumption of thermal light signal processingby using the method of ray Maxwell electromagnetic field theory, the method of three dimensional field of signal processinghas certain limitations, aiming at the problems of traditional electromagnetic fields ray method is optimized to improve, usethe place of traditional laser light source, LED cold light source signal is proposed cold light signals in optical fiber differen-tial equations of cylindrical three-dimensional field, through the cold light source signal wave vector k, light feature param-eter argument and propagation constant beta determine its in light sensor network model, adopt the method of multi-layersignal superposition of waves, with the same frequency and phase of LED light source for processing, then take intrusive-ness of the waves, the shortcomings of divergent and high energy consumption, finally using MATLAB simulation softwarecan analyze after stacking optimization of cold light source signals in the optical network transmission model, the simulationresults prove the effectiveness of the proposed method.
