【摘要】：随着物联网和GIS的融合与发展,GIS应用于物联网环境下传感器设备实时监控的研究成为GIS研究的重要热点,也是GIS发展的一个重要方向。相比于以列表形式显示传感器设备数据的传统方式,越来越多的研究旨在设计开发GIS管理传感器设备设施的更高效直接的数据可视化方式。组态软件在实时监控设备设施和数据实时可视化等技术上已相对成熟,但是其引入GIS仅作为背景地图,GIS丰富的管理功能未得到发挥,因此本文从GIS角度出发,开辟GIS地图与组态结合应用的新领域,创造出GIS管理传感器设备设施的新方式,为传感器设备设施管理提供一种高效便捷的方法。由于GIS与组态的可视化均是基于映射组织符号图元进行可视化表达,因此以矢量地图符号为枢纽,映射规则为驱动,设计研究在GIS中基于地图符号的组态方法。利用地图符号图元与组态的组织方式相似的特征,设计通用矢量地图符号,而鉴于SVG输出矢量图形的独特优势,以SVG格式图形为例设计自定义矢量地图符号抽象传感器设备为地图标识符号。通过分析传感器设备数据特征,创建其与地图符号图元的映射规则,由传感器设备数据的变化驱动地图符号视觉变量的改变,在地图上组态实现传感器设备数据的实时可视化。在移动客户端上设计应用程序APP,将基于地图符号的组态方法在移动GIS中进行验证。以开源且用户最多的Android操作系统为平台,搭载开源地图OSMDroid,修改其地图符号绘制方法使其支持矢量地图符号。通过自定义通信协议和即时通信协议MQTT进行传感器设备数据交互,在数据变化的同时重新渲染绘制地图符号,实现在移动GIS地图上通过地图符号组态实现数据的实时可视化。另外,该程序还提供列表数据展示、阈值修改和消息推送等丰富功能。
[Abstract]:With the integration and development of Internet of things and GIS, the application of GIS to real-time monitoring of sensor devices in the Internet of things environment has become an important research hotspot of GIS, and also an important direction of GIS development. Compared with the traditional way of displaying sensor device data in tabular form, more and more researches are aimed at designing and developing a more efficient and direct data visualization method for GIS management sensor device facilities. Configuration software has been relatively mature in real-time monitoring equipment facilities and data real-time visualization technology, but its introduction of GIS as a background map, GIS rich management function has not been played, so this paper from the point of view of GIS, This paper opens up a new field of application of GIS map and configuration, creates a new way of managing sensor equipment and facilities by GIS, and provides an efficient and convenient method for the management of sensor equipment facilities. Because the visualization of GIS and configuration is based on the mapping organization symbol elements, the configuration method based on map symbol in GIS is designed and studied, which is based on the vector map symbol as the hub and the mapping rule as the driving force. Based on the characteristics of map symbol elements similar to configuration organization, the general vector map symbols are designed. In view of the unique advantages of SVG output vector graphics, Taking the SVG graphic as an example, the self-defined vector map symbol Abstract Sensor device is designed as the map symbol. By analyzing the characteristics of sensor device data, the mapping rules between sensor device data and map symbol elements are created. The change of sensor device data drives the change of map symbol visual variable, and the real-time visualization of sensor device data is realized by configuration on map. The design of application APP, on mobile client verifies the configuration method based on map symbol in mobile GIS. Based on the open source and most user Android operating system, the open source map OSMDroid, is used to modify its map symbol rendering method to support vector map symbol. Through self-defined communication protocol and instant messaging protocol (MQTT), the sensor device data is interacted, and the map symbol is rerendered while the data changes. The real-time visualization of the data is realized by map symbol configuration on the mobile GIS map. In addition, the program also provides list data display, threshold modification and message push and other rich features.
