【摘要】：本文研究了水体去营养化过程中生物浮岛的优化布局与智能控制问题,分为五章对这一问题进行系统地介绍和研究。绪论中主要介绍了浮岛的研究背景、发展历史、应用前景、最新发展趋势以及文中课题的研究意义。第二章研究了圆形区域的分散布局问题,建立了两个基于不同目标的数学规划模型,将布局问题转化为模型的求解问题,并提出了一个界为1/2的近似算法,最终通过实例求解分析,验证了布局模型及理论的合理性与正确性,为浮岛的优化布局奠定了理论基础。第三章将浮岛的优化布局问题一分为二,建立多目标规划模型,分别解决了浮岛的使用数量、类型的选择和布局问题,改进分层布局近似算法,对比分析了利用改进后的近似算法和梯度方法求解的布局方案,并通过两个实例分析,进一步验证了布局模型和理论的正确性。第四章分析了生物浮岛的智能控制问题,设计了智能控制平台与系统,通过控制平台中的超声波传感器测算浮岛之间以及浮岛与水域边界间的距离,来控制浮岛的固定和漂移。通过控制系统实现浮岛的快速到达重污染水域净化水质,当水域中的水质达标后,还可以对浮岛进行列队排列,提升水域的景观价值。最后,总结全文,指出今后的工作和努力方向。
[Abstract]:In this paper, the optimal layout and intelligent control of biological floating islands in the process of water denutrition are studied, and this problem is systematically introduced and studied in five chapters. The introduction mainly introduces the research background, development history, application prospect, the latest development trend and the research significance of this paper. In the second chapter, we study the distributed layout problem of circular region, establish two mathematical programming models based on different objectives, transform the layout problem into a solution problem of the model, and propose an approximate algorithm with a bound of 1 / 2. Finally, the rationality and correctness of the layout model and the theory are verified by solving an example, which lays a theoretical foundation for the optimization of the layout of floating islands. In the third chapter, the optimal layout of floating islands is divided into two parts, and a multi-objective programming model is established, which solves the problems of the number of floating islands, the selection of types and the layout, and improves the approximate algorithm of layering layout. The layout scheme which is solved by the improved approximate algorithm and the gradient method is compared and analyzed, and the correctness of the layout model and theory is further verified by two examples. In chapter 4, the intelligent control problem of biological floating island is analyzed, and the intelligent control platform and system are designed. The distance between floating island and the boundary between floating island and water area is measured by ultrasonic sensor in the control platform to control the fixed and drift of floating island. Through the control system, the fast arrival of the floating island to the heavily polluted water area is realized. When the water quality in the water reaches the standard, the floating island can be arranged in line to enhance the landscape value of the water area. Finally, the paper summarizes the full text and points out the future work and direction.
