Dragon Gate National Grain Depot Grain Temperature And Humidity Monitoring System For The Design And Realization

"The design and realization of Longmen country grain depot information and observation system "is its inviting bids project . As a software technical engineer, I work together with the company getting the bid——Luoyang Tongfang science and technology Ltd., and take part in the system design of this project .Moreover, I am in charge of the software design and development work. The paper first introduces the item research background,the developments researched in the home and abroad,the significance of project and problem being resolved.and then, it introduces item research background information,system design,detail design .Finally, it gives an introduction of the item test situation. The end product of the project is a food information observation system. This paper introduce the item research design methods in the "Background information "section,including software engineering's design idea,design methods,pattern of supervising system,food information observation system's hardware resource,theory and methods of software design and so on. This paper introduced the observation system design objective needs analysis,design means,the collectivity design and composition of software and hardware, and so on.The "detail design "section introduces the systems concrete design situation of software and hardware .The hardware section consists of hardware's brands,standard,performance index,amount,composition,the communication mode and so on. The software section consists of software selection,systematic function module and the stream of work. Longmen country grain depot food information observation system,exerted the software engineering's analysis design means .It is thorough and scientific. Adopting advanced "A gleam of bus"technique,having achieved the design concept -join much figure temperature sensors to a stream,it has simplified the hardware composition.It lows the design cost.The software terrace adopts country stipulation Access and the optimal matching software-Visual Basic6.0.Designing technique employs the freshest database to control technique ADO to join the data resource,and heightens the hardware visit capability of Visual Basic6.0 through using the application programming interface ( API ) and others dynamic link library ( DLL ) and employing the ActiveX that can enrich export interface. The features of Longmen country grain depot food information observation system are:the well-developed research methods,rightful design,security and reliability,powerful functionality. The end of test accords with the country cereals food department. The systematic interface feature is very abundant. For example, the monitoring interface is direct and clear,he operation means is simple and diversified ,the warning means is obvious and projecting ,and the export interface types are rich. The system is remained beforehand "Ventilation","The hand is grasp the extension"interface .It has extended function,that can satisfy different demands of food information monitoring. The application of this system,proposing one kind of pragmatic food information examining implementation scheme and the intelligence control pattern .It is of significance to modernize the administration of the country grain reserves. This research project has better economic benefit,social benefit and a good application future.
