| With the rapid development of information technology and the production management mode ofagriculture, agricultural technology extension work is facing great opportunities and challenges, fromthe promotion of the subject to the object, from the thought to the real demand, rapid infiltration ofmodern factors in every aspect. Agricultural extension data collection as one of the core functions ofagricultural technology promotion cloud platform, is an important source of data, provides the datasupport for the promotion of management and service, also faces the difficult challenge: how to give fullplay to the advantage of grass-roots farming mobility to achieve high speed of data collection,completely changed the condition of untimely data collection; how to ensure the on-site data acquisitionauthenticity, to prevent deception maximumly and provide data support for the agricultural managementsystem assessment; how to make through data transmission and realize the data exchange, even toguarantee the communication quality through technical means under the rural development stages of thewireless network.The mobile communication technology and the supporting equipment develop rapidly, wireless networkis covering all over the country, Android intelligent equipment rapid popularization and peopleinformation awareness, provide convenient conditions for the solution of the above problem. Datacollection system based on Android around the core user of agricultural technology extension worksinvolved, to guarantee the reliability of data collection from the three level of data content, dataexchange and application software to achieve data collection accurate and timely, complete andconsistent; transmission channel patency; function module is easy to use, and safe software.Data accuracy of content ensured by the user real name, experts to participate in the review, sourcetagging, the integrity of the data content guaranteed by data synchronization of server and client, dataconsistency checked with text description, photos, geographic location and acquisition time attributes,timely data collection realize by making full use of the mobile wireless, portable, flexible characteristicsof android intelligent equipment. The data transmission reliability considering the effect of interactionon network environment and the bandwidth of communication on the quality of data exchange, datareal-time interactive, delay interactive and secure interactive finished by the data exchangetechnology.Timely response to customer demand by the rapid iteration, short cycle version updates ofthe agile development, combined with project management idea. User experience improved accordingto mobile design, friendly interface design, simple function operation, version of the automaticupgrade.The mobile application’s ability of anti crack enhanced by the security mechanism of androidprogram level and configuration level etc. Reliable system of Agro-Extension data collection based onandroid constituted by all of the aboves.The agricultural workers become the main body of agricultural technology extension work from the passive acceptance to active participation, and the agricultural technology extension organizationmanagement "flat" made by the principle "platform upward, downward continuation service" ofagricultural cloud platform. Reliable system of Agro-Extension data collection based on android can beused by agro-technique extension worker to submit promotion log and price of agriculturalproducts,report agricultural disaster and prescription,exchange experience and q&a to form data supportto better understand and master the condition of agro-technique work, agricultural production, marketand the primary concern and demand point in order to improve agricultural technology extensionmanagement, provide more localized and targeted information service, even then enhance the userviscosity. Resource content construction of agricultural technology promotion cloud platform can beexecuted by agro-technique extension workers and local experts through reliable system ofagro-extension data collection based on android to enhance the function of grassroots agriculturalextension service and promote sustainable development of platform operation. |
