【摘要】：隨著各行各業(yè)信息化的飛速發(fā)展,全球信息化統(tǒng)一的時代正在快速來臨,各行各業(yè)的高度信息化推動了科學(xué)技術(shù)的飛速發(fā)展。在發(fā)展的過程中,導(dǎo)航信息作為發(fā)展的重點之一在人民的日常生活中占據(jù)越來越重要的地位。衛(wèi)星導(dǎo)航模擬源技術(shù)是未來國家會高度重視的一個專業(yè)方向,衛(wèi)星導(dǎo)航模擬源技術(shù)可以在技術(shù)上實現(xiàn)和真實GPS導(dǎo)航衛(wèi)星相同的定位精度,衛(wèi)星導(dǎo)航模擬源技術(shù)的負債模擬導(dǎo)航電文的模擬,這對目前過度的依賴GPS定位系統(tǒng)有很大的緩解作用。目前,移動設(shè)備不能參與GPS直接定位原因是研發(fā)成本較高,摒棄對基站的依賴,通過模擬導(dǎo)航源技術(shù)進行實時定位是偏遠地區(qū)的定位的最佳選擇。通過分析模擬源技術(shù)的難點和關(guān)鍵技術(shù),進行現(xiàn)有成熟技術(shù)配合新技術(shù)的開發(fā)模式進行設(shè)計,結(jié)合實際在工作中發(fā)生的各類情況,對頂層動態(tài)監(jiān)測違法土地使用的軟件仿真系統(tǒng)進行研究,將系統(tǒng)分為三個部分分別是數(shù)據(jù)采集模塊,數(shù)據(jù)分析模塊和數(shù)據(jù)信息處理模塊。在使用巡查系統(tǒng)之前,系統(tǒng)內(nèi)部的模擬導(dǎo)航源已經(jīng)開啟,進行定位工作記錄執(zhí)法人員的運行軌跡。數(shù)據(jù)的采集主要是對發(fā)生違法土地地理信息的記錄方式,可以進行拍照錄像的方式采集違法信息,這些數(shù)據(jù)可以通過3G,4G網(wǎng)絡(luò)上傳GIS服務(wù)器進行數(shù)據(jù)的分析。模擬源軟件的前端和后端的設(shè)計實現(xiàn)并且完成了在沒有真實衛(wèi)星或者衛(wèi)星信號偏弱的情況下的定位,并可以根據(jù)實際工作中的違法土地的巡視繪制巡視路線圖,可以在巡視路線的軌跡上繪制違法土地的位置信息。
[Abstract]:With the rapid development of information technology in various industries, the era of global information unification is coming rapidly, and the high informatization of various industries has promoted the rapid development of science and technology. In the process of development, navigation information, as one of the key points of development, occupies a more and more important position in people's daily life. Satellite navigation analog source technology is a professional direction that countries will attach great importance to in the future. Satellite navigation analog source technology can achieve the same positioning accuracy as real GPS navigation satellite. The debt simulation of satellite navigation simulation source technology simulates the simulation of navigation message, which has a great mitigation effect on the excessive dependence on GPS positioning system at present. At present, the reason why mobile devices can not participate in GPS direct positioning is the high research and development cost, abandoning the dependence on base station, and real-time positioning through analog navigation source technology is the best choice for remote areas. Through the analysis of the difficulties and key technologies of the simulation source technology, the existing mature technology is designed in conjunction with the development mode of the new technology, combined with all kinds of actual situations in the work. The software simulation system for dynamic monitoring of illegal land use at the top level is studied. The system is divided into three parts: data acquisition module, data analysis module and data information processing module. Before using the inspection system, the analog navigation source inside the system has been turned on, and the positioning work has been carried out to record the running track of the law enforcement personnel. The collection of data is mainly to record the geographical information of illegal land, which can be photographed and videotaped to collect illegal information. These data can be uploaded to GIS server through 3G and 4G network for data analysis. The front end and back end of the analog source software are designed and implemented and the positioning is completed without the real satellite or the satellite signal is weak, and the inspection road map can be drawn according to the illegal land inspection in the actual work. The location information of illegal land can be drawn on the track of patrol route.
