【摘要】：在節(jié)能減排顯得尤為重要的今天，作為煤炭消費(fèi)大戶的火力發(fā)電廠，非常有必要提高其煤場管理水平，做到燃煤分類堆放，提高煤場空間利用率，減少燃煤堆放周期，阻止煤料自燃，最大限度的保存燃煤發(fā)熱量，及時統(tǒng)計煤場存煤情況等，以避免燃料無形中的浪費(fèi)，節(jié)約燃煤開支，提高企業(yè)效益。本文試圖建立一個網(wǎng)頁上的煤場可視化圖形系統(tǒng)以提高煤場管理的信息化程度，，作為提升煤場管理水平的一種手段。 煤場可視化圖形將計算機(jī)視覺技術(shù)引入到電力生產(chǎn)領(lǐng)域中，對煤場進(jìn)行可視化3D建模，建立數(shù)字化煤場，提供包括煤堆位置、成分、存煤量、堆積狀態(tài)等在內(nèi)的詳細(xì)信息，同時將這些信息直觀形象化，幫助煤場管理人員及時感知煤場動態(tài)、查看煤場存煤情況，方便規(guī)劃購煤、配煤摻燒。 信息技術(shù)的進(jìn)步日新月異，在網(wǎng)絡(luò)上實現(xiàn)計算機(jī)視覺的Web3D技術(shù)也隨之出現(xiàn)。WebGL技術(shù)是一種新型的網(wǎng)頁虛擬實現(xiàn)技術(shù)，用于網(wǎng)頁三維繪圖，無需插件，可適應(yīng)火電企業(yè)內(nèi)部的網(wǎng)絡(luò)環(huán)境條件。本文研究了多種網(wǎng)頁三維繪圖技術(shù)，最后以WebGL技術(shù)為主要開發(fā)手段，結(jié)合jQuery、Oak3D等工具框架，在Web上實現(xiàn)了一個煤場的3D可視化圖形系統(tǒng)。該圖形系統(tǒng)圖像渲染效果良好，高度逼真地還原了煤場的三維外形，整個模型具有非常強(qiáng)的立體感，通過拖動鼠標(biāo)，就可以從多角度觀察煤場的燃煤堆放情況。該系統(tǒng)初步實現(xiàn)了網(wǎng)頁上的煤場三維可視化設(shè)想。
[Abstract]:Today, it is particularly important to save energy and reduce emissions. As a large consumer of coal, it is very necessary to improve the level of coal yard management, to achieve coal-fired classified stacking, to improve the space utilization rate of coal yard, and to reduce coal stacking cycle. In order to avoid the waste of fuel, save the expenditure of coal and improve the benefit of enterprises, we can prevent spontaneous combustion of coal, preserve the heat of coal to the maximum, and count the situation of coal storage in coal yard in time, so as to avoid the waste of fuel inconspicuously. This paper attempts to establish a visual graphic system of coal yard on the web page in order to improve the information level of coal yard management as a means to improve the level of coal yard management. The visualization graph of coal field introduces computer vision technology into the field of electric power production, carries on the visualization 3D modeling to the coal field, establishes the digitized coal field, provides the detailed information including the coal pile position, the composition, the coal storage quantity, the accumulation state, and so on. At the same time, these information can be visualized intuitively to help the managers of the coal yard to perceive the dynamic of the coal field in time, to check the situation of coal storage in the coal yard, and to make it convenient to plan and purchase coal and mix coal with burning. With the rapid development of information technology, the Web3D technology of realizing computer vision on the network also appears. WebGL technology is a new virtual web page implementation technology, which is used for three-dimensional drawing of web pages without plug-in. Can adapt to the internal network environment conditions of thermal power enterprises. In this paper, many kinds of three-dimensional drawing technology of web pages are studied. Finally, a 3D visualization graphics system of coal field is implemented on Web with WebGL technology as the main developing means and jQuery,Oak3D and other tools framework. The image rendering effect of the graphics system is good and the three-dimensional shape of the coal field is restored highly realistically. The whole model has a very strong sense of three-dimensional. By dragging the mouse, we can observe the coal-fired stacks from many angles. The system preliminarily realizes the three-dimensional visualization of coal field on the web page.
