摘要
针对常规保密通信自动监测系统稳定性较低,吞吐量不足的问题,设计一种基于NB-IoT的光接入网保密通信自动监测系统.构建系统硬件选取STM32F101R6芯片构建主控盘,使用信号集中器设计信号采集与处理设备,连接继电器控制监测系统电压;根据CoAP协议控制NB-IoT数据传输,并将NB-IoT中的信号依照TDOA方法进行信号区域定住,实现基于NB-IoT保密通信自动监测系统软件设计.实验结果表明:与常规保密通信自动监测系统相比,设计的自动监测系统稳定性比常规系统高出7.25%,吞吐量也随着监测时长而稳步提升.由此可见,设计的基于NB-IoT的光接入网保密通信自动监测系统性能更优越,更符合实际工作需求.
To solve the low stability and insufficient throughput of conventional secure communication automatic monitoring system,a NB-Iot-based optical access network secure communication automatic monitoring system is designed.STM32F101R6 chip is selected to build the main control panel.Signal collector is used to design signal acquisition and processing equipment.Relay is connected to control and monitor system voltage.NB-Iot data transmission was controlled in accordance with CoAP protocol,and signals in NB-Iot were positioned in signal area in accordance with TDOA method,realizing software design of NB-Iot secure communication automatic monitoring system.The experimental results show that the stability of the designed automatic monitoring system is 7.25% higher than that of the conventional automatic monitoring system,and the throughput increases steadily with the monitoring time.Therefore,the NB-Ilot designed optical access network secure communication automatic monitoring system is superior in performance and more in line with the actual work requirements.
