【摘要】：我國(guó)煤礦井下自動(dòng)化監(jiān)控系統(tǒng)種類多、數(shù)量大，但各個(gè)系統(tǒng)自成體系，互不兼容，造成了煤礦井下出現(xiàn)多套監(jiān)控系統(tǒng)并存的局面，造成了資源的極大浪費(fèi)。物聯(lián)網(wǎng)技術(shù)的興起和發(fā)展，為這些系統(tǒng)的整合提供了統(tǒng)一的網(wǎng)絡(luò)平臺(tái)，同時(shí)也為實(shí)現(xiàn)全礦井的無(wú)線覆蓋、人員及設(shè)備的定位和感知提供了新的技術(shù)手段。作為感知礦山物聯(lián)網(wǎng)系統(tǒng)的重要組成部分，井下無(wú)線定位系統(tǒng)擔(dān)負(fù)著井下人員和設(shè)備的實(shí)時(shí)定位、環(huán)境感知、以及指導(dǎo)災(zāi)后搜救等重要任務(wù)，是保證煤礦安全生產(chǎn)的重要途徑和手段。但無(wú)線定位節(jié)點(diǎn)一般采用電池供電，能量有限，特別是物聯(lián)網(wǎng)定位系統(tǒng)中的無(wú)線節(jié)點(diǎn)，有時(shí)還要擔(dān)負(fù)音頻甚至視頻信號(hào)的采集和傳輸，能量開(kāi)銷非常大。因此，能量的消耗是制約無(wú)線定位系統(tǒng)井下應(yīng)用的主要因素。無(wú)線電能傳輸技術(shù)的發(fā)展，為井下無(wú)線設(shè)備的供能提供了新的思路。通過(guò)無(wú)線輸能系統(tǒng)，可以保證井下無(wú)線節(jié)點(diǎn)的電量充足，不僅可以免去為數(shù)以千計(jì)無(wú)線節(jié)點(diǎn)更換電池的不變，還可以保證救災(zāi)時(shí)所有定位節(jié)點(diǎn)都具有充足的電量，完成遇險(xiǎn)人員搜救的任務(wù)。 為了實(shí)現(xiàn)上述目標(biāo)，本文提出了能夠應(yīng)用于礦山物聯(lián)網(wǎng)的基于WPT技術(shù)的無(wú)線定位系統(tǒng)。本文將從五個(gè)方面對(duì)相關(guān)關(guān)鍵技術(shù)進(jìn)行了闡述。首先，，以感知礦山示范工程為研究背景，以?shī)A河煤礦為例，分析國(guó)內(nèi)現(xiàn)有井下無(wú)線定位系統(tǒng)的現(xiàn)狀，找出其存在的問(wèn)題及不足，提出并設(shè)計(jì)了一種可用于物聯(lián)網(wǎng)的井下人員定位系統(tǒng)。其次，建立無(wú)線電磁波在工作面?zhèn)鬏數(shù)男诺滥Ｐ停岢隽斯ぷ髅鏌o(wú)線電波的傳輸定律(RTRWP Law)，并仿真分析了無(wú)線電磁波在工作面和巷道傳播時(shí)的差異，進(jìn)而為無(wú)線定位系統(tǒng)設(shè)計(jì)了兩種應(yīng)用于不同巷道環(huán)境的拓?fù)浣Y(jié)構(gòu)，此外，還給出了無(wú)線定位所需要的信號(hào)能量計(jì)算方法。第四，針對(duì)在兩種不同應(yīng)用環(huán)境的拓?fù)浣Y(jié)構(gòu)，提出了兩種相應(yīng)的定位算法，并進(jìn)行了仿真，結(jié)果表明，改進(jìn)的RSSI算法與經(jīng)典的RSSI算法相比能夠顯著地減少誤差。最后，也是最重要的部分，是為井下無(wú)線定位系統(tǒng)設(shè)計(jì)了電能的無(wú)線傳輸系統(tǒng)，為了將無(wú)線電能傳輸系統(tǒng)應(yīng)用于煤礦井下，本文提出了交疊圓式發(fā)送結(jié)構(gòu)，實(shí)驗(yàn)結(jié)果表明，交疊圓式諧振耦合式電能傳輸系統(tǒng)能
[Abstract]:There are many kinds and quantity of automatic monitoring system in coal mine in our country, but each system is self-contained and incompatible, which results in the co-existence of many monitoring systems in coal mine, and causes a great waste of resources. The rise and development of the Internet of things technology provides a unified network platform for the integration of these systems. At the same time, it also provides a new technical means for realizing the wireless coverage of the whole mine, the location and perception of personnel and equipment. As an important part of the mine and mountain networking system, the underground wireless positioning system is responsible for the real-time positioning of underground personnel and equipment, environmental awareness, as well as the guidance of post-disaster search and rescue and other important tasks. It is an important way and means to ensure safe production of coal mine. However, the wireless positioning node is usually powered by battery and has limited energy, especially the wireless node in the Internet of things (IoT) positioning system, sometimes it is responsible for the acquisition and transmission of audio and video signals, so the energy cost is very large. Therefore, energy consumption is the main factor restricting the downhole application of wireless positioning system. The development of radio energy transmission technology provides a new idea for the power supply of underground wireless equipment. Through the wireless energy transmission system, the underground wireless nodes can be guaranteed sufficient power, not only can the thousands of wireless nodes be replaced with the same battery, but also can ensure that all positioning nodes in disaster relief have sufficient power. Complete the search and rescue mission for distress personnel. In order to achieve the above objectives, this paper proposes a wireless positioning system based on WPT technology, which can be used in mine and mountain Internet of things. In this paper, the key technologies are described from five aspects. First of all, taking the demonstration project of perceptual mine as the research background and taking Jiahe Coal Mine as an example, this paper analyzes the present situation of the existing underground wireless positioning system in China, and finds out its existing problems and shortcomings. This paper presents and designs a downhole personnel positioning system which can be used in the Internet of things. Secondly, the channel model of the radio wave transmission in the working face is established, and the transmission law of the radio wave in the working face, (RTRWP Law), is put forward, and the difference of the radio magnetic wave propagation in the working face and the roadway is simulated and analyzed. Furthermore, two kinds of topology structures applied to different roadway environments are designed for the wireless positioning system. In addition, the calculation method of signal energy required for wireless positioning is also given. Fourthly, according to the topology structure in two different application environments, two corresponding localization algorithms are proposed and simulated. The results show that the improved RSSI algorithm can significantly reduce the error compared with the classical RSSI algorithm. Finally, the most important part is to design the wireless transmission system of electric energy for the underground wireless positioning system. In order to apply the radio energy transmission system to the underground coal mine, the overlapping circular transmission structure is proposed in this paper. The experimental results show that: Energy of overlapping circular resonant coupled power transmission system
