【摘要】：本文研究了水體去營養(yǎng)化過程中生物浮島的優(yōu)化布局與智能控制問題,分為五章對這一問題進(jìn)行系統(tǒng)地介紹和研究。緒論中主要介紹了浮島的研究背景、發(fā)展歷史、應(yīng)用前景、最新發(fā)展趨勢以及文中課題的研究意義。第二章研究了圓形區(qū)域的分散布局問題,建立了兩個基于不同目標(biāo)的數(shù)學(xué)規(guī)劃模型,將布局問題轉(zhuǎn)化為模型的求解問題,并提出了一個界為1/2的近似算法,最終通過實(shí)例求解分析,驗(yàn)證了布局模型及理論的合理性與正確性,為浮島的優(yōu)化布局奠定了理論基礎(chǔ)。第三章將浮島的優(yōu)化布局問題一分為二,建立多目標(biāo)規(guī)劃模型,分別解決了浮島的使用數(shù)量、類型的選擇和布局問題,改進(jìn)分層布局近似算法,對比分析了利用改進(jìn)后的近似算法和梯度方法求解的布局方案,并通過兩個實(shí)例分析,進(jìn)一步驗(yàn)證了布局模型和理論的正確性。第四章分析了生物浮島的智能控制問題,設(shè)計(jì)了智能控制平臺與系統(tǒng),通過控制平臺中的超聲波傳感器測算浮島之間以及浮島與水域邊界間的距離,來控制浮島的固定和漂移。通過控制系統(tǒng)實(shí)現(xiàn)浮島的快速到達(dá)重污染水域凈化水質(zhì),當(dāng)水域中的水質(zhì)達(dá)標(biāo)后,還可以對浮島進(jìn)行列隊(duì)排列,提升水域的景觀價值。最后,總結(jié)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.
