发布时间：2019-06-05 19:16
【摘要】：随着各行各业信息化的飞速发展,全球信息化统一的时代正在快速来临,各行各业的高度信息化推动了科学技术的飞速发展。在发展的过程中,导航信息作为发展的重点之一在人民的日常生活中占据越来越重要的地位。卫星导航模拟源技术是未来国家会高度重视的一个专业方向,卫星导航模拟源技术可以在技术上实现和真实GPS导航卫星相同的定位精度,卫星导航模拟源技术的负债模拟导航电文的模拟,这对目前过度的依赖GPS定位系统有很大的缓解作用。目前,移动设备不能参与GPS直接定位原因是研发成本较高,摒弃对基站的依赖,通过模拟导航源技术进行实时定位是偏远地区的定位的最佳选择。通过分析模拟源技术的难点和关键技术,进行现有成熟技术配合新技术的开发模式进行设计,结合实际在工作中发生的各类情况,对顶层动态监测违法土地使用的软件仿真系统进行研究,将系统分为三个部分分别是数据采集模块,数据分析模块和数据信息处理模块。在使用巡查系统之前,系统内部的模拟导航源已经开启,进行定位工作记录执法人员的运行轨迹。数据的采集主要是对发生违法土地地理信息的记录方式,可以进行拍照录像的方式采集违法信息,这些数据可以通过3G,4G网络上传GIS服务器进行数据的分析。模拟源软件的前端和后端的设计实现并且完成了在没有真实卫星或者卫星信号偏弱的情况下的定位,并可以根据实际工作中的违法土地的巡视绘制巡视路线图,可以在巡视路线的轨迹上绘制违法土地的位置信息。
[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.
