Research And Development Of The Mobile GIS Technology Based On The Android System

In recent years,due to the rapid development of economy in Zhangjiakou area,the regional distribution network becomes more and more complex,staff inspection work of distribution line is divided into regular and irregular points,the two plays a very important role and can ensure the safe operation of equipment and power distribution lines.Grid patrol inspection has the following methods to record the contents of the inspection line,including manual records,fill out the defect ticket record defects,but the efficiency of these methods is not high,automation degree low,can not satisfy the current situation of demand.In order to complete the inspection work efficiently,the transition from manual recording to automated electronic recording is imperative.According to Zhangjiakou for inspection work experience in Zhangjiakou before the inspection work mode are summarized,and the need to improve the place and keep the.First of Zhangjiakou Power Distribution inspection work were functional requirements analysis,through the analysis to find the development system requires power grid spatial data real-time mapping,navigation data logging and patrol path acquisition,repair vehicle navigation and vehicle monitoring,off-line GIS development,improve the economic benefit and other functions,and Study on how to realize the function.Finally,the offline GIS technology,database technology,SVG map rendering,path optimal planning,road navigation technology,GPS positioning technology in mobile handheld terminal of distribution network complex line,inspection.The practical application shows that the system is suitable for use in Zhangjiakou,and the positioning accuracy and correctness of the data meet the requirements,can greatly improve the work efficiency and economic benefit,has the value of promotion.
