【摘要】：隨著物聯(lián)網(wǎng)和GIS的融合與發(fā)展,GIS應用于物聯(lián)網(wǎng)環(huán)境下傳感器設備實時監(jiān)控的研究成為GIS研究的重要熱點,也是GIS發(fā)展的一個重要方向。相比于以列表形式顯示傳感器設備數(shù)據(jù)的傳統(tǒng)方式,越來越多的研究旨在設計開發(fā)GIS管理傳感器設備設施的更高效直接的數(shù)據(jù)可視化方式。組態(tài)軟件在實時監(jiān)控設備設施和數(shù)據(jù)實時可視化等技術上已相對成熟,但是其引入GIS僅作為背景地圖,GIS豐富的管理功能未得到發(fā)揮,因此本文從GIS角度出發(fā),開辟GIS地圖與組態(tài)結合應用的新領域,創(chuàng)造出GIS管理傳感器設備設施的新方式,為傳感器設備設施管理提供一種高效便捷的方法。由于GIS與組態(tài)的可視化均是基于映射組織符號圖元進行可視化表達,因此以矢量地圖符號為樞紐,映射規(guī)則為驅(qū)動,設計研究在GIS中基于地圖符號的組態(tài)方法。利用地圖符號圖元與組態(tài)的組織方式相似的特征,設計通用矢量地圖符號,而鑒于SVG輸出矢量圖形的獨特優(yōu)勢,以SVG格式圖形為例設計自定義矢量地圖符號抽象傳感器設備為地圖標識符號。通過分析傳感器設備數(shù)據(jù)特征,創(chuàng)建其與地圖符號圖元的映射規(guī)則,由傳感器設備數(shù)據(jù)的變化驅(qū)動地圖符號視覺變量的改變,在地圖上組態(tài)實現(xiàn)傳感器設備數(shù)據(jù)的實時可視化。在移動客戶端上設計應用程序APP,將基于地圖符號的組態(tài)方法在移動GIS中進行驗證。以開源且用戶最多的Android操作系統(tǒng)為平臺,搭載開源地圖OSMDroid,修改其地圖符號繪制方法使其支持矢量地圖符號。通過自定義通信協(xié)議和即時通信協(xié)議MQTT進行傳感器設備數(shù)據(jù)交互,在數(shù)據(jù)變化的同時重新渲染繪制地圖符號,實現(xiàn)在移動GIS地圖上通過地圖符號組態(tài)實現(xiàn)數(shù)據(jù)的實時可視化。另外,該程序還提供列表數(shù)據(jù)展示、閾值修改和消息推送等豐富功能。
[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.
