【摘要】：采礦業(yè)是國(guó)民經(jīng)濟(jì)的基礎(chǔ)行業(yè),我國(guó)的采礦業(yè)大多為地下采礦。井下地質(zhì)條件復(fù)雜,有的巷道長(zhǎng)達(dá)數(shù)千米,設(shè)備作業(yè)點(diǎn)分散,流動(dòng)性大,加之巷道與采掘工作面空間狹窄,導(dǎo)致井下作業(yè)人員無法判斷自身當(dāng)前位置以及周邊的環(huán)境設(shè)施,存在極大的事故隱患。此外,全球定位系統(tǒng)(GPS)的成功應(yīng)用使人們對(duì)于定位導(dǎo)航的服務(wù)需求越來越多,人們希望能將其移植到井下環(huán)境中去。但由于地質(zhì)條件的限制,GPS信號(hào)無法穿透地表到達(dá)地下。而射頻識(shí)別技術(shù)(RFID)具有非視距、非接觸、成本低且發(fā)展成熟等優(yōu)點(diǎn),得到了越來越廣泛的關(guān)注,成為了優(yōu)選的室內(nèi)定位技術(shù)。近年來,關(guān)于RFID室內(nèi)定位的研究取得了較大的發(fā)展。其定位方法總體上可以劃分為兩大類,一類是基于測(cè)量距離的定位方法,另一類是基于場(chǎng)景分析的定位方法。本文對(duì)這兩類方法分別做了詳細(xì)的介紹,對(duì)基于場(chǎng)景分析的定位方法做了較為深入的研究,先通過程序開發(fā),驗(yàn)證了文中設(shè)計(jì)的匹配算法確實(shí)能搜索到差異最小的指紋信息,具有可行性。為了降低人力、物力的消耗,利用克里金插值技術(shù),對(duì)場(chǎng)景分析定位方法提出了改進(jìn),通過程序開發(fā),證明了改進(jìn)后的場(chǎng)景分析定位方法能獲得更好的定位性能。由于該方法具有諸多優(yōu)點(diǎn),因此將改進(jìn)后的場(chǎng)景分析定位方法確定為適合于本設(shè)計(jì)的井下定位方法。確定好定位方法之后,本設(shè)計(jì)對(duì)導(dǎo)航系統(tǒng)的整體結(jié)構(gòu)進(jìn)行了設(shè)計(jì),將導(dǎo)航系統(tǒng)分成為幾個(gè)基本的子系統(tǒng)。通過定位子系統(tǒng)、網(wǎng)絡(luò)子系統(tǒng)、語音子系統(tǒng)、視頻監(jiān)控子系統(tǒng)以及擴(kuò)展信號(hào)系統(tǒng)的合理構(gòu)建,完成了導(dǎo)航系統(tǒng)硬件的體系設(shè)計(jì)。接著,對(duì)導(dǎo)航系統(tǒng)的軟件部分進(jìn)行設(shè)計(jì),通過對(duì)無軌設(shè)備車載觸摸屏及監(jiān)控中心監(jiān)控系統(tǒng)的結(jié)構(gòu)組態(tài)與功能界面設(shè)計(jì),構(gòu)成了完整的井下無軌膠輪設(shè)備導(dǎo)航系統(tǒng)。本設(shè)計(jì)解決了只能“遠(yuǎn)程看”的傳統(tǒng)定位模式,實(shí)現(xiàn)了系統(tǒng)的可視化、可聽化、可交流化、可識(shí)別化。有利于司機(jī)安全、有序、高效的駕駛無軌設(shè)備,同時(shí)還有利于管理人員進(jìn)行合理調(diào)度與有效管理。
[Abstract]:Mining industry is the basic industry of national economy, the mining industry of our country mostly is underground mining. The underground geological conditions are complex, some roadways are thousands of meters long, the equipment operating points are scattered, the mobility is large, and the space between the roadway and the mining face is narrow, which results in the downhole operators unable to judge their current position and the surrounding environmental facilities. There are great hidden dangers to the accident. In addition, the successful application of GPS (Global Positioning system) makes people need more and more services for positioning and navigation, and people hope to transplant it into underground environment. However, due to the limitation of geological conditions, GPS signals can not penetrate the surface to reach the ground. Radio frequency identification (RFID) technology has been paid more and more attention because of its advantages of non-visual distance, non-contact, low cost and mature development. In recent years, the research on RFID indoor positioning has made great progress. As a whole, the localization methods can be divided into two categories, one is based on measuring distance, the other is based on scene analysis. In this paper, the two kinds of methods are introduced in detail, and the location method based on scene analysis is studied deeply. First, through the development of program, it is verified that the matching algorithm designed in this paper can really search the fingerprint information with the least difference. It is feasible. In order to reduce the consumption of manpower and material resources, the method of scene analysis and location is improved by using Kriging interpolation technology. Through the development of program, it is proved that the improved method of scene analysis and location can obtain better localization performance. Because this method has many advantages, the improved scene analysis and localization method is determined to be suitable for this design. After determining the positioning method, the overall structure of the navigation system is designed, and the navigation system is divided into several basic subsystems. Through the reasonable construction of positioning subsystem, network subsystem, voice subsystem, video monitoring subsystem and extended signal system, the hardware architecture of navigation system is designed. Then, the software part of the navigation system is designed, through the structure configuration and function interface design of the trackless equipment on-board touch screen and the monitoring system of the monitoring center, a complete underground trackless rubber wheel equipment navigation system is constructed. This design solves the traditional positioning mode which can only be "remote watch", and realizes the visualization, audibility, communication and recognition of the system. It is beneficial to driver safety, order, efficient driving trackless equipment, but also conducive to the management of reasonable scheduling and effective management.
