【摘要】：隨著移動互聯(lián)網(wǎng)的高速發(fā)展和智能硬件的不斷普及,以GNSS為代表的的室外定位技術(shù)極大地改善了人們的生產(chǎn)和生活方式。與此同時(shí),室內(nèi)定位也產(chǎn)生了廣泛而切實(shí)地需求。超市的商品尋找、停車場的停車導(dǎo)航、地下礦井人員的定位保護(hù)、虛擬現(xiàn)實(shí)設(shè)備的定位追蹤等生活生產(chǎn)的很多方面都需要進(jìn)行室內(nèi)定位。其中,虛擬現(xiàn)實(shí)設(shè)備的定位由于虛擬現(xiàn)實(shí)潛在的市場價(jià)值被廣泛地研究。論文從現(xiàn)階段各種定位技術(shù)的對比出發(fā),發(fā)現(xiàn)超聲波定位技術(shù)在虛擬現(xiàn)實(shí)設(shè)備定位中具有定位精度高、布局簡單、抗干擾強(qiáng)、成本低等優(yōu)勢。然后論文具體分析了超聲波定位技術(shù)的原理,然后結(jié)合虛擬現(xiàn)實(shí)設(shè)備的應(yīng)用場景,提出了一套超聲波室內(nèi)定位系統(tǒng)。超聲波室內(nèi)定位系統(tǒng)以超聲波傳感器為定位核心,具體包括超聲波發(fā)射子系統(tǒng)、超聲波接收子系統(tǒng)、數(shù)據(jù)傳送子系統(tǒng)和后臺操控及處理中心。按照應(yīng)用需求,后臺操控及處理中心發(fā)出定位指令后,超聲波發(fā)射子系統(tǒng)發(fā)射超聲波信號和用于同步計(jì)時(shí)的射頻信號。超聲波接收子系統(tǒng)接收到射頻信號和超聲波信號后將定位數(shù)據(jù)計(jì)算出來并傳送給后臺操控及處理中心。后臺操控及處理中心負(fù)責(zé)處理定位數(shù)據(jù)并將目標(biāo)的三維坐標(biāo)解算出來,然后顯示給用戶。數(shù)據(jù)傳送子系統(tǒng)起到通信橋梁的作用。論文在介紹了超聲波室內(nèi)定位系統(tǒng)的設(shè)計(jì)方案后,從硬件、軟件兩個(gè)層面對系統(tǒng)的設(shè)計(jì)進(jìn)行了分析。硬件部分包括系統(tǒng)各部分的電路設(shè)計(jì)、PCB設(shè)計(jì)和焊接調(diào)試;P CB設(shè)計(jì)在Altium Designer 10下完成。軟件方面包括系統(tǒng)的底層軟件編寫、上位機(jī)編寫和數(shù)據(jù)庫設(shè)計(jì);底層軟件采用C語言在Keil uvision 4、IAR Embedded Workbe nch 8.20下完成;上位機(jī)采用C++語言在Qt Creater 4.2.1下完成,其中的數(shù)據(jù)處理部分使用MATLAB R2014a完成;數(shù)據(jù)庫使用MySQL數(shù)據(jù)庫存儲定位數(shù)據(jù)。最后在實(shí)驗(yàn)室中搭建了系統(tǒng)的測試環(huán)境,進(jìn)行了功能測試和結(jié)果分析。本論文設(shè)計(jì)和實(shí)現(xiàn)的的超聲波室內(nèi)定位系統(tǒng)經(jīng)過測試,能夠滿足虛擬現(xiàn)實(shí)設(shè)備的定位需求。經(jīng)過改進(jìn),也可應(yīng)用于室內(nèi)機(jī)器人定位、倉庫用導(dǎo)航小車等,具有應(yīng)用價(jià)值。
[Abstract]:With the rapid development of mobile Internet and the popularization of intelligent hardware, the outdoor positioning technology, represented by GNSS, has greatly improved the people's production and life style. At the same time, the indoor positioning has also produced a wide and practical demand. The search for goods in the supermarket, the parking navigation of the parking lot, the location protection of underground mine personnel, The positioning and tracking of virtual reality equipment need to be located in many aspects of living production. The location of virtual reality equipment is widely studied because of the potential market value of virtual reality. This paper, starting from the comparison of various positioning techniques at the present stage, finds that the ultrasonic positioning technology is in the position of virtual reality equipment. With the advantages of high positioning precision, simple layout, strong anti-interference and low cost, the principle of ultrasonic positioning technology is analyzed in this paper. Then a set of ultrasonic indoor positioning system is put forward in combination with the application scene of virtual reality equipment. The ultrasonic wave sensor is the core of the ultrasonic indoor positioning system, including ultrasonic emission. Sub-system, ultrasonic receiving subsystem, data transmission subsystem and background control and processing center. Ultrasonic emitter system launches ultrasonic signals and radio frequency signals for synchronous timing according to application requirements, background manipulation and processing center sends out positioning instructions. The ultrasonic receiving subsystem receives radio frequency signals and ultrasonic signals. The positioning data is calculated and transmitted to the backstage manipulation and processing center. The backstage manipulation and processing center handles the positioning data and calculates the three-dimensional coordinates of the target, then displays it to the user. The data transmission subsystem plays the role of the communication bridge. After introducing the design of the ultrasonic indoor positioning system, the paper introduces the design of the ultrasonic indoor positioning system. The design of the system is analyzed from two layers of hardware and software. The hardware part includes the circuit design of all parts of the system, the design of PCB and the welding debugging; the design of P CB is completed under the Altium Designer 10. The software includes the software of the system, the writing of the upper computer and the design of the data base; the bottom software uses the C language in Keil uVision 4. The IAR Embedded Workbe NCH 8.20 is completed; the host computer uses the C++ language in Qt Creater 4.2.1, and the data processing part is completed using MATLAB R2014a; the database uses the MySQL database to store the data. Finally, the system test environment is built in the laboratory, and the function test and result analysis are carried out. This paper is designed in this paper. And the implementation of the ultrasonic indoor positioning system after testing, can meet the positioning requirements of virtual reality equipment. After improvement, it can also be applied to indoor robot positioning, the warehouse with navigation cars, and so on, has the application value.
