Abstract


In order to raise the overall technical level of tobacco cultivation and management process tobacco pest monitoring, forecasting and prevention and control, and software technology to build the tobacco pest early warning system to monitor the growth of tobacco state has gradually become one of the important research direction of tobacco cultivation and production management. , The tobacco pest early warning system development-oriented tobacco companies tobacco production has been more and more people are concerned about, but the establishment of early warning and control system of the existing the tobacco pest and disease early warning system was not up to standard, there are a few functions, the interactive run inefficient processing information in a timely manner as well as the deployment and upgrade difficulties such as lack of. Tobacco companies tobacco pest data acquisition in the tobacco growing process, the formation of the the warning Figure and dynamic investigation line graph functional requirements for the application of background, Silverlight and WCF technologies to build a service-oriented B / S mode tobacco pest warning system (hereinafter referred to TPASYS). End using Silverlight browser technology, survey line chart dynamically generated the tobacco pest warning map and draw pest expert scientific diagnose the illness, release control measures play a key role in guiding. The server side using a layered architecture, data communications through WCF service access, warning map data in a remote data communication between server-side and browser-side Silverlight application. Meet the business needs of the tobacco management department at the same time, the system also has a rich user interface and the strong interaction, and efficient operation characteristics, greatly enriching the user experience, and improve work efficiency and decision-making level of support of the tobacco sector. The main work of this paper include: research background for TPASYS current research status of tobacco production in the practical application significance as well as the theoretical basis of the graphic warning. ② the TPASYS functional and non-functional requirements, analysis existing TPASYS graphics warning, the lack of dynamic line graph drawing and pest statistics function. ③ Analysis demand of TPASYS, the design TPASYS WCF service interface layer, data access layer, business logic layer and the Web interface presentation layer multilayer architecture, detailed design and all levels module. ④ Research NET Framework 3.5 release contains LINQ database access technology in the data access layer of the system of multi-tier architecture of the TPASYS the operating methods of the underlying database access package. ⑤ WCF technology the system multilayer architecture WCF service interface layer with TPASYS of graphic warning function module data in the browser Web applications and server-side remote communication. ⑥ study Silverlight3.0 technology and realized TPASYS draw some graphical controls and business data encapsulation method, the graphic warning custom controls in the Silverlight application in the browser, the rendering of dynamic line chart and pest and disease information data histogram statistics and other functions. The actual deployment of applications that, the paper proposes graphic warning the tobacco pest warning, convenient interactive, efficient data processing, publish real-time early warning information on tobacco production industry has an important theoretical significance and value of the project.
