摘　　要：当前物联网通信系统存在耗能高以及准确性差等问题,为此设计基于光纤供能技术的物联网通信系统,系统采用S3C2440芯片作为微控制器进行总体控制,通过光纤传感器采集信息以及传输光信号,通过ARM微控制器处理收集电信号,采用远程单元数据发送协议以及中心基站数据接收协议对光纤传感节点工作模式以及电信号传递过程实施调整和处理,软件系统通过BP神经网络融合光纤传感器数据,整合压缩数据后提升数据的传递速度,采用阻抗匹配跟踪方法基于负载与PPC内部阻抗匹配获取最高的功率点,使得光纤传感器驱动性能和输出电功率提高。实验结果表明,本文系统准确性和可靠性高、功耗低。The Internet communication system has problems of high energy consumption and poor accuracy.For this purpose,the Internet of things communication system based on optical fiber supply technology is designed. The system uses S3 C2440 chip as a microcontroller to control the whole system,collect information and transmit light signal through optical fiber sensor,and collect the data through ARM micro controller.The electrical signal,using the remote unit data transmission protocol and the central base station data receiving protocol,adjusts and processes the operation mode of the optical fiber sensor nodes and the transmission process of the electrical signal. The software system integrates the number of fiber sensor data through the BP neural network and integrates the compressed data to improve the transmission speed of the data,and uses the impedance match.The matching tracking method is based on the matching of load and PPC internal impedance to get the highest power point,so that the driving performance and output power of optical fiber sensor are improved.The experimental results show that the system has high accuracy and reliability,and low power consumption.
