在不同变量的河流、湖泊和水库等不确定环境中进行近实时水质监测,对于保护水生生物和防止水中潜在污染的进一步传播至关重要。为了测量感兴趣区域的物理值,自适应采样作为一种能源和时间效率高的技术是有帮助的,因为用一辆车对一个区域进行彻底搜索是不可行的。我们提出了一种自适应采样算法,使用多智能体强化学习(MARL)框架中训练有素的多辆自动驾驶汽车作为智能体,在自适应采样过程中做出有效的决策序列。利用实验数据对所提出的解决方案进行了评估,并将其输入到仿真框架中。实验于2019年7月在新泽西州萨默塞特郡的拉坦河和普林斯顿的卡内基湖进行。
Near-real-time water-quality monitoring in uncertain environments such as rivers, lakes, and water reservoirs of different variables is critical to protect the aquatic life and to prevent further propagation of the potential pollution in the water. In order to measure the physical values in a region of interest, adaptive sampling is helpful as an energy- and time-efficient technique since an exhaustive search of an area is not feasible with a single vehicle. We propose an adaptive sampling algorithm using multiple autonomous vehicles, which are well-trained, as agents, in a Multi-Agent Reinforcement Learning (MARL) framework to make efficient sequence of decisions on the adaptive sampling procedure. The proposed solution is evaluated using experimental data, which is fed into a simulation framework. Experiments were conducted in the Raritan River, Somerset and in Carnegie Lake, Princeton, NJ during July 2019.
