| The data diversity and difficult data acquisition is the bottleneck restricting the farmland information acquisition. In recent years, a new method for farmland data collection is provided with the rapid development of information and mobile intelligent terminal in 3G mobile network. Mobile intelligent terminal in the mainstream market provide kinds of operating system, like Android, IOS, Windows Phone, but there is transplanting difficulty and long development period because of the differences of development language and development tools in most mobile apps. A set of cross -platform farmland data acquisition system based on PhoneGap framework was designed, in order to analyze farmland information and classify data types. SQLite was used as master database, and HTML5 LocalStorage was used as caching data module for the system. The data tables of sampling point, parcel information, insect pests and soil nutrient were built, in addition, farmland environmental information was collected with GPS or network positioning, to realize centralized management of farmland information. The design of the system not only can improve the efficiency of data acquisition, also reduce the cost of data acquisition. |
