Research On The Key Technology Of Intelligent High-frequency Agricultural Products Acquisition System

With rapid development in information construction,innovation and application of data-capture technology gradually penetrates into various fields,such as military,agriculture and medical care.As the Intelligent data acquisition equipment appear,that has changed the ways of agricultural production, the circulation of agricultural products and Data acquisition. Made the acquisition and processing method of data from Agricultura lproduction and management turning paper into computer which has greatly improved the effectiveness and reliability of data acquisition,meanwhile it achieve The possibility of real-time monitoring and statistics. Under this background, the paper aimed at research of the key technology of the data acquisition of agricultural products system,designs a set of data acquisition system that is used in agricultural data acquisition, information storage, wireless communication and other functions, which satisfy the growing requirements of the acquisition and processing of the data of agricultural products.According to the present design method of the data acquisition, this paper base on the embedded system,developing a high frequency intelligent data acquisition system suit for Agricultural data collection,presenr research and discussions on the key technology of the design process for the hardware and software. The main research work includes the following aspects:1According to the lack of the products for agricultural data acquisition"system,based on the embedded system development, Completed the design of intelligent high frequency agricultural products data acquisition system, According to the specialties of application choose the hardware components.2Combining design of the embedded system hardware and circuit principle knowledge,completed the design of hardware system, involves four modules,incluing RFID data acquisition module, ethernet interface module, the power module, LCD color touch screen module.3Based on the design for hardware, In order to ensure the normal operation of the system,after the appropriate choice for the version of The embedded operating system,Base on the The WINCE5.0operating system and its own Embedded Visual C++language design and the function of the code,such as Serial communication interface function. Develop a set of RFID coding schemes for feasible agricultural products electronic label, vegetables as an example, using the EPC SGTIN-96code to the rule the design, puts forward a scheme of data writing.4Based on the test of some part of the application module of this system, validate software and hardware for compatibility, The experimental results show that the design of the system preliminary reach the expected results,which can achieve the requirements of system RFID RF data acquisition, data exchange and storage functions etc.
