| Liangshan is the country’s second largest city-level tobacco leaf producing area, and is an important national strategic tobacco leaf base with good quality. It’s now transforming from the traditional tobacco production to modern tobacco agriculture with the characteristics of "large-scale production, intensive management, specialization operation and informationization management". It has become an urgent task to extend information technology to every link of production and management, make use of the means of information technology to transform traditional tobacco leaf production and promote the development of modern tobacco agriculture. In the process of tobacco production and management, the acquisition, logistics and storage of tobacco leaf are several extremely important links as well as key factors affecting the quality of tobacco. This thesis studies how to build an information platform of tobacco leaf production and management for the above links to make effective management and control to the process and realize normative and efficient operation of business.Based on the goal of "standardized management, improving quality and serving for farmers", the thesis synoptically describes the status of construction and application of the tobacco information system, makes a detailed analysis of the needs of every business process, makes optimization and recycling on part of the process in conjunction with requirements of enterprise management and implements the overall design of tobacco production and management information platform based on it.As for specific implementation, firstly, it makes use of bank card of double media and integrated RFID chip, integrates contract card and bank card of farmer, and regards it as the only credential to sign a contract, deliver and sell tobacco and cash tobacco earning, thus it enhances security, confidentiality and durability of tobacco-delivering card and find a good solution to the problem of farmers authentication through the third-party authentication.Secondly, taking into account several links which tobacco production and management involves such as tobacco leaf acquisition, electronic settlement, tobacco logistics, tobacco storage and so on, as well as factors including the intensive dependence among the various types of business, the developing and changing of new demand and increasingly flexible demanding for way of data revelation, it selects a more advanced service-oriented architecture as the infrastructure of system software that will enable various business modules in the platform realize information exchange and information sharing. The software development makes use of the MVC design pattern to ensure that the platform has good scalability and user-friendly interface.Finally, in order to better adapt to the wet, dusty, unstable voltage environment of tobacco area, in the tobacco workstation and warehousing center it develops its own embedded device used for business data collection, storage, management and node control of business process. |
