【摘要】：為實(shí)現(xiàn)我國(guó)成為民航強(qiáng)國(guó)的目標(biāo),我國(guó)民航業(yè)迅速發(fā)展,機(jī)場(chǎng)噪聲對(duì)周圍人民的影響也日益嚴(yán)重。機(jī)場(chǎng)噪聲等值線圖,可直觀顯示出機(jī)場(chǎng)對(duì)其附近區(qū)域的噪聲影響狀況,為機(jī)場(chǎng)管理部門提供機(jī)場(chǎng)噪聲控制及土地規(guī)劃依據(jù),動(dòng)態(tài)的機(jī)場(chǎng)噪聲等值線圖可直觀反映出機(jī)場(chǎng)周邊區(qū)域噪聲實(shí)時(shí)情況,為管理部門制定出降噪飛行計(jì)劃提供依據(jù)。本文首先對(duì)機(jī)場(chǎng)噪聲監(jiān)測(cè)系統(tǒng)現(xiàn)狀進(jìn)行分析,提出了面向泛網(wǎng)格式機(jī)場(chǎng)噪聲監(jiān)測(cè)點(diǎn)布局的概念,并說明了泛網(wǎng)格式分布的機(jī)場(chǎng)噪聲監(jiān)測(cè)點(diǎn)布局對(duì)于首都噪聲監(jiān)測(cè)的重要作用,而后分析了泛網(wǎng)格式布局的機(jī)場(chǎng)噪聲監(jiān)測(cè)點(diǎn)會(huì)對(duì)繪制機(jī)場(chǎng)噪聲等值線帶來的問題,并對(duì)國(guó)內(nèi)外機(jī)場(chǎng)噪聲可視化文獻(xiàn)進(jìn)行了研究分析,將機(jī)場(chǎng)噪聲預(yù)測(cè)與機(jī)場(chǎng)噪聲等值線相結(jié)合得出本文基于泛網(wǎng)格式布局的機(jī)場(chǎng)噪聲監(jiān)測(cè)點(diǎn)可并行的噪聲等值線繪制模型。針對(duì)泛網(wǎng)格式布局的機(jī)場(chǎng)噪聲監(jiān)測(cè)點(diǎn)分布特點(diǎn),首先將機(jī)場(chǎng)按泛網(wǎng)格數(shù)據(jù)分布特點(diǎn),以區(qū)域內(nèi)監(jiān)測(cè)點(diǎn)密度是否能夠支持直接繪制噪聲等值線為區(qū)域劃分原則,將機(jī)場(chǎng)噪聲監(jiān)測(cè)區(qū)域進(jìn)行劃分。隨著區(qū)域劃分的完成,機(jī)場(chǎng)噪聲等值線繪制任務(wù)也隨之分割成為每個(gè)區(qū)域內(nèi)等值線繪制的子任務(wù),建立并行繪制模型。而后,對(duì)于不可直接繪制噪聲等值線區(qū)域,利用機(jī)場(chǎng)歷史監(jiān)測(cè)數(shù)據(jù)及機(jī)場(chǎng)噪聲預(yù)測(cè)軟件并應(yīng)用本文提出算法對(duì)該區(qū)域內(nèi)噪聲數(shù)據(jù)進(jìn)行生成,使得各區(qū)域內(nèi)均為網(wǎng)格式的數(shù)據(jù),各區(qū)域內(nèi)應(yīng)用等值線追蹤算法對(duì)網(wǎng)格數(shù)據(jù)進(jìn)行處理生成等值線追蹤路徑,最后將各區(qū)域內(nèi)等值線追蹤路徑進(jìn)行連接、擬合,完成對(duì)一幅機(jī)場(chǎng)噪聲等值線圖的繪制,應(yīng)用本文彌補(bǔ)數(shù)據(jù)傳輸與動(dòng)態(tài)繪制之間差異的算法,對(duì)機(jī)場(chǎng)進(jìn)行動(dòng)態(tài)的噪聲等值線繪制。
[Abstract]:In order to realize our country's goal of becoming a strong country of civil aviation, the civil aviation industry of our country has developed rapidly, and the influence of airport noise on the people around is becoming more and more serious. The noise isoline map of the airport can directly show the noise influence of the airport on the adjacent area, and provide the airport management department with the basis for the noise control and land planning of the airport. The dynamic contour map of airport noise can directly reflect the real time noise around the airport and provide the basis for the management department to formulate the noise reduction flight plan. In this paper, firstly, the present situation of airport noise monitoring system is analyzed, and the concept of airport noise monitoring point layout oriented to pan-grid is put forward, and the important function of airport noise monitoring point layout with pan-grid distribution for capital noise monitoring is explained. Then it analyzes the problems caused by airport noise monitoring points with pan-grid layout, and studies and analyzes the visualization literature of airport noise at home and abroad. By combining airport noise prediction with airport noise isoline, a parallel noise contour drawing model of airport noise monitoring points based on pan-grid layout is proposed in this paper. In view of the distribution characteristics of airport noise monitoring points in pan-grid layout, firstly, according to the characteristics of pan-grid data distribution, the regional division principle is whether the density of monitoring points in the region can support the direct drawing of noise isolines. The noise monitoring area of the airport is divided. With the completion of the region division, the airport noise contour drawing task is divided into sub-tasks of isoline drawing in each region, and a parallel rendering model is established. Then, for the noise isoline region that can not be drawn directly, using the airport history monitoring data and airport noise prediction software and applying the algorithm presented in this paper to generate the noise data in the region, the data in each region are grid type. The contour tracing algorithm is used to process the grid data to generate the contour tracing path. Finally, the contour tracing path in each region is connected and fitted to complete the drawing of an airport noise contour map. In this paper, the algorithm of bridging the difference between data transmission and dynamic rendering is used to draw the dynamic noise contour of the airport.
