Application of Underwater Operation Monitoring and Emergency Rescue Technology Based on Internet of Things

研究水下作业监控及救援问题。针对传统的水下作业监测系统中的终端节点不便携带,网络部署和维护成本高,难以自适应采集监控区域内各种水下作业数据和实时预警并实施水下救援等问题,分布式多传感异步网络提出了一种实时水下作业监测及应急救援的物联网技术。以监测分簇为单位构建异步通信网络,部署不同类型的传感器终端节点如温度、湿度、噪声传感器等,基于分布式传输技术针对不同性质的水下作业采集各种类型的水下作业环境和人员定位数据,同时根据监测数据对水下作业人员建立危险预警机制。仿真结果和分析表明,物联网技术对各种类型水下作业实施监测及实现远程数据判读,具有高可靠性的实时预警,并有效地增强了监控网络的生存周期。

The underwater exploration was researched. Based on distributed multi - sensor asynchronous net- work, the paper presented a network technology of real - time underwater operation monitoring and emergency rescue. Taking monitoring cluster as unit, the technique constructs asynchronous communication network, the deploys differ- ent types of sensors such as temperature, humidity, and the terminal node noise sensors. Based on the distributed transmission technology and according to the different natures of the underwater operations, various types of underwa- ter operation environments and personnel positioning data were acquired. At the same time, according to the monito- ring data of underwater operation, the early warning mechanism for personnel risk was built up. Simulation experi- ment and mathematical analysis show that the technology can monitor all types of underwater operations and interprete remote data, the real - time early warning is of high reliability, and the monitoring network life cycle is effectively en- hanced.
