针对突发性水污染事件应急监测和智能模拟分析需求,研究了多传感器立体协同监测模型,建立了突发性水污染事件的时间、空间属性和传感器观测性能之间的相关关系,实现了卫星、无人机、地面、水上平台的动态、协同组网。在丹江口库区开展了突发性水污染事件动态组网立体监测实验分析,根据水污染事件发生时、动态演变过程中和事件后期3个阶段的不同观测需求,基于多传感器立体协同监测模型,深入开展了多传感器协同优化求解,确定了相应的观测平台及传感器。实验结果表明,协同、高效的“天空地一体化”立体感知网能够全面、精准、快速获取水污染事件监测信息,可以科学支撑突发性水污染事件的应急处置。
Abstract
This paper addresses the need for emergency monitoring and intelligent simulation in response to sudden water pollution events.We established the correlations of sensor performance with time,space,and attributes and constructed a multi-sensor synergetic monitoring model to accomplish the dynamic and collaborative sensing through a network of satellite,UAV(Unmanned Aerial Vehicle),ground and water platforms.We selected Danjiangkou Reservoir as a demonstration area for dynamic network monitoring of sudden water pollution events. Based on the specific observation requirements during the occurrence,dynamic evolution,and later stages of water pollution events,we determined the corresponding platforms and sensors required. Experimental results manifest that the proposed multi-sensor network captures the water pollution monitoring information comprehensively,accurately,and rapidly. Moreover,it provides scientific support for emergency response and treatment of sudden water pollution events.
