为实现远距离通信覆盖，提升监控数据的完整性，提出基于LoRa无线网络和集对分析的舰船航行安全监控系统。利用电罗经与多普勒计程仪，实时采集航向与航速等舰船航行数据；通过终端节点与网关节点组建LoRa无线网络，传输舰船航行数据至监控终端，实现远距离通信覆盖，提升监控数据的完整性；监控终端通过集对分析方法处理舰船航行数据，计算舰船航行的多元联系数，监测舰船航行安全态势，并执行对应的分级控制策略，完成舰船航行安全监控。实验证明，在不同扩频因子下，该系统数据成功传输率均较高，最低成功传输率约为0.90；该系统可有效实现舰船航行安全监控，确保舰船始终按照安全轨迹航行。
In order to achieve long-distance communication coverage and improve the integrity of monitoring data, a ship navigation safety monitoring system based on Lora wireless network and set pair analysis is proposed. The compass and Doppler log are used to collect real-time ship navigation data such as course and speed; Lora wireless network is established through terminal node and gateway node to transmit ship navigation data to the monitoring terminal, so as to realize long-distance communication coverage and improve the integrity of monitoring data; The monitoring terminal processes the ship navigation data through the set pair analysis method, calculates the multiple connection number of ship navigation, monitors the ship navigation safety situation, and implements the corresponding hierarchical control strategy to complete the ship navigation safety monitoring. Experiments show that the system has a high data success rate under different spread spectrum factors, and the minimum success rate is about 0.90; The system can effectively realize the ship navigation safety monitoring and ensure that the ship always navigates according to the safe trajectory.
