【摘要】：随着经济的发展,机动车数量不断增加,为了提高本部门的车辆行驶安全与效率,各单位对所属车辆均加强了管理。油田作业车辆监控研究需要解决的问题就是知道自己所处的位置以及在车辆如何在平台软件上显示自己的位置。传统的方法是基于GPS+GPRS通信的组合方式,但是这种方式在石油领域存在局限性。部分油田位于没有通讯网络覆盖的偏远地区,以及移动运营商通讯基站覆盖不佳的地方,导致被监控的车辆无法向平台报告自己的位置。同时,企业专门建设通讯基站,建设成本维护成本高昂。此外,油区基础设施,如站库、管线、油区道路等位置坐标属于保密信息,在生产过程中需确保这类信息的安全。北斗卫星导航作为我国自主研发的导航系统,有利于摆脱对国外导航系统的依赖,有利于维护我国的经济、信息和国防安全。北斗导航主要有RDSS和RNSS两种导航方式,前者具有报位功能,可向平台报告自己的位置而不依赖于基站等其它设施。北斗短报文功能保证终端可向平台发送位置。监控平台软件在显示地图及地物的同时,同时也需要对平台显示界面进行优化,防止显示重要地理要素时,其它无关地理要素同时显示对其的遮挡,影响使用者的阅读体验。本文首先分析了Map Server的工作流程,通过Mapfile,实现了基于Map Server的监控平台的电子地图发布。设计了一种平台显示优化方法,解决了对不同级别地理要素进行自动分类,同时实现在不同比例尺下对分类结果进行分级别显示,通过不同符号样式对分类结果进行显示上的区分的问题。优化了使用者的阅读体验,提高了地图加载效率。并将Map Server与平台框架其它部分进行对接。然后介绍了Eclipse开发环境和Android的配置过程,设计了基于Android的终端软件的地图显示功能和位置定位功能。详细介绍了原理、实现过程及关键部分代码,展示了功能实现结果。
[Abstract]:With the development of economy, the number of motor vehicles is increasing, in order to improve the safety and efficiency of vehicles in this department. All units have strengthened their management of their vehicles. The problem that needs to be solved in vehicle monitoring and control research in oil field operations is to know where they are and how to display their position on the platform software. The traditional method is that:---. Based on GPS. A combination of GPRS communications. But this approach has limitations in the oil world. Some oilfields are located in remote areas where there is no communication network coverage, and where mobile operator base stations are not well covered. As a result, the monitored vehicles can not report their location to the platform. At the same time, the enterprises are specialized in the construction of communication base stations, which is costly to build and maintain. In addition, the oil area infrastructure, such as depots and pipelines. Location coordinates such as roads in oil area are classified information. Beidou satellite navigation, as a independently developed navigation system in China, is helpful to get rid of the dependence on foreign navigation system. Beidou navigation has two kinds of navigation modes: RDSS and RNSS, the former has the function of reporting position. Can report their location to the platform without relying on the base station and other facilities. Beidou short message function ensures that the terminal can send the location to the platform. The monitoring platform software display maps and features at the same time. At the same time, we also need to optimize the platform display interface to prevent the display of important geographical elements, other independent geographical elements at the same time show its occlusion. First of all, this paper analyzes the workflow of Map Server through Mapfile. The electronic map publishing of monitoring platform based on Map Server is realized. A platform display optimization method is designed, which solves the problem of automatic classification of geographical elements of different levels. At the same time, the classification results are displayed at different scales, and the classification results are distinguished by different symbol styles. The reading experience of users is optimized. The efficiency of map loading is improved and the Map Server is docked with other parts of the platform framework. Then the Eclipse development environment and the configuration process of Android are introduced. The map display function and position location function of terminal software based on Android are designed. The principle, realization process and key code are introduced in detail, and the result of function realization is shown.
