Design And Development Of The Fieldbus Equipment Management System Based On B/S Mode

With the development of computer communication technology and equipment information management technology,staffs in factories or enterprises don't have to go to the field of equipment workstation to collect the information and then analyse or manage them.The application of the fieldbus technology makes the equipment information can be read directly by computer equipment and parsed.As such,the security,absoluteness and unity of the equipment information in the system are in great security.Enterprise managers don't have to go to the scene to check the information in the devices workstation,they use the application of the fieldbus technology to get the information what they want.This ensures the personal safety of the managers,even in some ways,also improve the reliability of equipment operation process.Before,the design of the management system of the field bus equipment is based on the C/S mode.Usually,the design pattern of C/S mode requires the system to run on the client side with a quit large-scale,and the client part is more bloated,the client side of the computer hardware configuration requirements are also higher.Users must be trained in advance in order to carry out reasonable operation.When installing into the system,the software based on C/S mode should be first judged the environment of the client running on,including its hardware facilities and operating system,and its application in the background.This makes the workload greatly increase.At the same time,it also requires the designer to develop the different stage,which increase the workload greatly.The field bus equipment management system based on B/S mode is put forward on the basis of the above.Management system with B/S mode as the development model,use C# as the development language,use MySQL Database as the underlying database,is designed as a system that can display the field bus equipment information.Management system achieve the function of the display of the equipment tree and equipment information,and the function of the sort of the equipment information,such as the show of the equipment of the historical data,the historical curve drawing,etc..Also,it is designed with the statistical functions for different types of equipment information,and can analyse the service life of the equipment,which based on the historical data.System is designed with the module of the management of the user and role,and can distinguish permissions between the users of the management system in detail.The management system based on B/S mode of the fieldbus devices in the computer platforms is particularly important,its development will surely become the important direction in equipment management.For fieldbus devices,equipment data acquisition is more convenient.Fieldbus devices,after the message was read out by the server,will be displayed on the computer for users to browse and view,by the Web technology.Such information browsing becomes simple and easy to perform,and bring great convenience to operators and maintenance personnel.It is a necessary choice of the development of equipment information management in the future.
