Design And Implementation Of Electronic Map Field Collection Function Based On Android Platform

Currently major electronic map manufacturers use the manual field acquisition method to collect data,and the acquisition equipment is essential for efficiency.Therefore,the field data acquisition function based on Android platform enjoys a good application prospect in the field acquisition with its portability and universality,which can achieve digitalization and high efficiency of data acquisition.Firstly,through the analysis and comparison of the operating systems of the major mobile devices in the market,this paper explained why chose Android platform as the program for development.The open source of Android platform cuts the cost of development,and its rich components and class library reference effectively simplify the program development,so that it can be used as a carrier platform for field data acquisition functions.Secondly,based on the research of related Android technology,the system structure and application framework of Android system were specifically described.The operation mechanism of Android application and the design mode of MVC were expounded by analyzing the functional components in the application framework.According to the above technology research,the feasibility of designing and developing the field data acquisition system based on Android platform was analyzed,and the basic functions of the field data acquisition were designed by linking the functional analysis of the system.This program mainly realizes the functions of account management,data search,map display,data acquisition,data transmission and GPS positioning as well as the corresponding UI design.Among them,the main program interfaces are the initial login interface and map display interface which is mainly used to display map data.GPS positioning receives the user’s device location information to display it on the main map interface.Account management function uses data management verification of user name and password for the security of the program.Data acquisition and search module work and search according to the data.Data transmission module transmits data via network.With POI data structure as an example,this paper expounded the design method of SQLite database.Finally,the actual usability of data acquisition function on Android platform was demonstrated by function and performance test.By contrasting to the traditional acquisition mode,the advantages of Androidbased field acquisition function were elaborated from acquisition equipment,data storage and process simplification.Such field acquisition function simplifies the traditional acquisition process and upgrades the operation mode of field acquisition through electronic informationization of acquisition process,thereby improving the efficiency of field production personnel,avoiding and solving many practical problems for field acquisition.
