【摘要】：隨著科技的進步,人們對智能終端的需求與日俱增,并且人們對智能終端提供的服務(wù)提出了更多和更高的要求。近年來,基于位置的服務(wù)發(fā)展迅速并極大地改善了人們的生活,互聯(lián)網(wǎng)時代的SoLoMo已經(jīng)成為新的發(fā)展趨勢。因此,智能終端一項必不可少的功能就是滿足用戶的精準(zhǔn)定位需求。 目前,我國自主研發(fā)的北斗衛(wèi)星導(dǎo)航系統(tǒng)已完成了對東南亞地區(qū)的覆蓋,并已經(jīng)在我國的軍用、民用領(lǐng)域發(fā)揮了重要作用,其可以為授權(quán)用戶提供定位、測速、授時和通信等服務(wù)。本文詳細(xì)介紹了北斗系統(tǒng)定位的基本原理,即如何通過北斗系統(tǒng)來獲取用戶的位置信息,包括經(jīng)度、維度、高度和速度等。由于在計算用戶位置坐標(biāo)的過程中存在許多干擾因素,從而影響了定位的精準(zhǔn)度,所以,本文又分析了北斗系統(tǒng)定位過程中存在的誤差源,并提出了一些解決方法和措施來減弱和消除這些誤差。 北斗導(dǎo)航定位系統(tǒng)中北斗接收機的一個典型應(yīng)用就是與移動終端設(shè)備相結(jié)合,準(zhǔn)確獲取這些終端的位置信息,并同時利用應(yīng)用軟件系統(tǒng)對這些終端進行綜合管理,如智能物流系統(tǒng)和車輛監(jiān)控系統(tǒng)等。本文第二部分詳細(xì)介紹了這樣一個終端位置管理系統(tǒng)的設(shè)計和開發(fā)。為了提高開發(fā)效率并保證系統(tǒng)的穩(wěn)定性,該系統(tǒng)采用了基于MVC設(shè)計模式的SSH框架。該系統(tǒng)面向三級用戶,不同級別的用戶訪問系統(tǒng)的權(quán)限不同,也從系統(tǒng)獲取的服務(wù)不同。該系統(tǒng)主要由5個功能模塊組成,即信息管理、信息查詢、軌跡回放、電子圍欄和片區(qū)監(jiān)控。這些功能模塊既獨立又統(tǒng)一,能夠高效地管理車輛終端并對用戶提供便捷的服務(wù)。在這部分的最后,針對片區(qū)監(jiān)控模塊的開發(fā)過程中遇到的判斷點與多邊形位置關(guān)系的難點,本人提出的一種改進的算法很好地解決了這個問題。 最后,針對論文中終端位置管理系統(tǒng)的應(yīng)用場景、系統(tǒng)需求以及系統(tǒng)總體設(shè)計目標(biāo),使用單元測試、系統(tǒng)測試和壓力測試這三種軟件測試方法對系統(tǒng)中五個核心的功能模塊進行了測試。測試結(jié)果表明該管理系統(tǒng)設(shè)計合理、功能正常、性能良好,達(dá)到了預(yù)期目標(biāo)。
[Abstract]:With the development of science and technology, the demand for intelligent terminals is increasing day by day, and people put forward more and higher requirements for the services provided by intelligent terminals. In recent years, location-based services have developed rapidly and greatly improved people's lives. SoLoMo in the Internet era has become a new development trend. Therefore, an essential function of intelligent terminals is to meet the needs of accurate positioning of users. At present, the Beidou satellite navigation system, which has been independently developed in China, has completed its coverage of Southeast Asia and has played an important role in the military and civilian fields of our country. It can provide positioning and speed measurement for authorized users. Services such as time service and correspondence. In this paper, the basic principle of Beidou system positioning is introduced in detail, that is, how to obtain the user's position information through Beidou system, including longitude, dimension, height and speed, etc. Because there are many interference factors in the process of calculating the location coordinates of the users, which affects the accuracy of the positioning, the error sources in the positioning process of the Beidou system are analyzed in this paper. Some solutions and measures are put forward to reduce and eliminate these errors. A typical application of Beidou receiver in Beidou navigation and positioning system is to get the position information of these terminals accurately by combining with the mobile terminal equipment, and at the same time to use the application software system to carry on the comprehensive management to these terminals. Such as intelligent logistics system and vehicle monitoring system. The second part of this paper introduces the design and development of such a terminal position management system in detail. In order to improve the development efficiency and ensure the stability of the system, the system adopts SSH framework based on MVC design pattern. The system is oriented to three levels of users, different levels of users have different permissions to access the system, but also from the system to obtain different services. The system is mainly composed of five functional modules, namely, information management, information query, track playback, electronic fence and area monitoring. These functional modules are independent and unified, can efficiently manage vehicle terminals and provide convenient services to users. At the end of this part, in view of the difficulty of judging the relationship between the point and the position of the polygon in the development of the monitoring module, I put forward an improved algorithm to solve this problem very well. Finally, according to the application scene, system requirement and the overall design goal of the terminal position management system in this paper, the unit test is used. Three software testing methods, system testing and stress testing, test the five core functional modules of the system. The test results show that the management system is reasonable in design, normal in function and good in performance.
