Research And Implementation For A Mobile Devices Rice Cultivation Data Acquisition System

China is the origin country of rice cultivation in the world. Rice is not only the majorfood crops for Chinese, but also the major food crops all over the world. Rice is not only akind of major source of food, but also an important raw material for industry. The plantingand growth for the rice is of great significance for the national economy.Smartphone is a mobile device, which is small, cheap, and easy to carry. Compared withthe PC, it is more convenient for rice cropping’s data collection in agricultural productionstaff is concerned.Based on the Android smart phone application development, the Rice cropping dataacquisition system has achieved the agricultural production of rice parental informationmanagement, information management rice leaf tillers, rice detection informationmanagement, production information management end smartphone data collection functions.Based on the requirements of ‘Rice cropping data acquisition system’, this paper mainlyfocuses on how to use relative technology to finalize the design of the software. Main findingsare listed as below.First of all, this paper introduces the application development technology for androidsoftware system. Main technologies are listed as below, the system architecture of androidplatform, composition of android applications, main components of an android application,database technology for android applications, the life cycle of the activity, and thecommunication mechanism between two android activities.Base on android application development technology, this paper analyzes the hardwareenvironment and the software environment of the ‘Rice cropping data acquisition system’.Also, this papter analyzes user roles, the business processing of the software, and theplatformfunctional requirements and performance requirements.Based on the needs analysis for this project, logical and physical models are designs.This article analyzes the level of the project development, design of the rice cropping dataacquisition system software structure, the software system of data needed to logical modeland physical model, design software interface between various levels required by the systemand its implementation, and designed five modules, namely, corn parents management module,corn leaves tiller management module, corn detection management module, informationmanagement module, user management module.Using UML for system software logic designand component design.Based on the hierarchical development thinking, different levels of the rice cropping data acquisition system, the development of sub-module, completed the detailed design of thetable layer, data layer, the database adapter, activities, complete software system interfacedesignto complete the physical design of the rice cropping data acquisition system.By using android development technology and Java, this paper put forward a solutionfor the’ Rice cropping data acquisition system’.Finally, the paper summarizes the strengths and the weaknesses of the software. Inaddition, the paper requests the task for the future work.
