【摘要】：近年來(lái),隨著科技的不斷進(jìn)步,人們對(duì)各個(gè)行業(yè)和領(lǐng)域的自動(dòng)化程度要求越來(lái)越高。堆位測(cè)量(礦山、碼頭的物料堆等)作為重要的國(guó)民生產(chǎn)領(lǐng)域技術(shù),也在不斷的改進(jìn)和發(fā)展。傳統(tǒng)的測(cè)量方法不僅效率低,而且對(duì)于礦山這些地理環(huán)境比較復(fù)雜的地方,測(cè)量人員的安全問(wèn)題也會(huì)受到威脅。針對(duì)這些問(wèn)題,本文提出一種基于激光測(cè)距原理構(gòu)建的傳感系統(tǒng),既可用于大型礦場(chǎng)、碼頭的物料測(cè)量,也可用于礦山安全與智能采礦系統(tǒng)。單一傳感器對(duì)于多傳感器而言,測(cè)量速度比較慢。故本文將利用多傳感器融合定位技術(shù),這樣獲取目標(biāo)數(shù)據(jù)會(huì)更快更準(zhǔn)確,主要工作如下:(1)對(duì)多種激光測(cè)距方案進(jìn)行了研究和比較,根據(jù)應(yīng)用情況,對(duì)測(cè)距傳感系統(tǒng)發(fā)射模塊的激光驅(qū)動(dòng)電路及接收模塊的前置放大電路、主放大電路和時(shí)間測(cè)量電路進(jìn)行了設(shè)計(jì),分析了產(chǎn)生測(cè)距誤差的影響因素,選取合適的器件和設(shè)計(jì)方案。(2)分析陸基導(dǎo)航定位和星基導(dǎo)航定位系統(tǒng),并選擇GPS定位系統(tǒng)與測(cè)距傳感系統(tǒng)進(jìn)行融合。根據(jù)GPS定位系統(tǒng)與測(cè)距傳感系統(tǒng)的原理及特點(diǎn),將兩個(gè)系統(tǒng)融合在一起,構(gòu)成一個(gè)GPS激光測(cè)距傳感系統(tǒng),并對(duì)該傳感定位系統(tǒng)的各個(gè)子模塊進(jìn)行設(shè)計(jì)。(3)完成了無(wú)人機(jī)搭載GPS激光測(cè)距傳感系統(tǒng)對(duì)礦場(chǎng)及其他物料堆進(jìn)行測(cè)量的系統(tǒng)設(shè)計(jì),對(duì)無(wú)人機(jī)機(jī)載GPS激光測(cè)距傳感系統(tǒng)進(jìn)行三維測(cè)量和數(shù)據(jù)處理的方法進(jìn)行了研究。本論文提出的這種測(cè)量系統(tǒng),具有重要的理論和現(xiàn)實(shí)意義,在礦山測(cè)量和堆位測(cè)量領(lǐng)域具有廣泛的應(yīng)用前景。
[Abstract]:In recent years, with the continuous progress of science and technology, people demand more and more automation in various industries and fields. As an important national production technology, stack measurement (mine, wharf material pile, etc.) has been continuously improved and developed. Traditional survey methods are not only inefficient, but also threaten the safety of surveyors in places with complex geographical environment. Aiming at these problems, this paper presents a sensing system based on the principle of laser ranging, which can be used for material measurement in large mines and wharves as well as mine safety and intelligent mining systems. For multiple sensors, the measurement speed of a single sensor is relatively slow. Therefore, this paper will use multi-sensor fusion localization technology to obtain target data faster and more accurately. The main work is as follows: 1) Research and comparison of various laser ranging schemes, according to the application, The laser driving circuit of the emitter module of the ranging sensor system and the preamplifier circuit of the receiving module, the main amplifier circuit and the time measuring circuit are designed. The influencing factors of the ranging error are analyzed. Select the appropriate device and design scheme. 2) analyze the land-based navigation and satellite-based navigation and positioning system, and select the GPS positioning system and ranging sensor system for fusion. According to the principle and characteristics of GPS positioning system and ranging sensing system, the two systems are fused together to form a GPS laser ranging sensing system. And the sub-modules of the sensing and positioning system are designed. 3) the system design of measuring mine field and other material stacks with GPS laser ranging sensing system for UAV is completed. The methods of three-dimensional measurement and data processing for airborne GPS laser ranging sensing system of UAV are studied. The measurement system proposed in this paper has important theoretical and practical significance and has a wide application prospect in the field of mine survey and heap survey.
