Research And Implementation Of Communication Alarm Management And Maintenance System Based On .NET Technology

Communication alarm system is widely used in petroleum,chemical,metallurgy,power plant,coal and other fields.It has the advantages of diverse communication methods,low cost,complete functions and simple installation methods.However,due to the strong noise,large-scale,corrosive special environment and the large number of equipment in the industrial production site,the safe and effective management and background maintenance of the communication alarm system is very important.This paper studies the effective management and background maintenance of communication alarm system,and designs a communication alarm management and maintenance system software based on.NET technology,which realizes the functions of monitoring,data configuration,delivery and call,Signal forwarding and management control of the entire industrial production site communication alarm system.Aiming at the problem of allocation of access control authority in communication alarm management and maintenance system,a concept-based authority configuration method and generate hierarchical roles based on Hasse graph characteristics.The application of this model can reduce the complexity of system access rights management,and effectively avoid the security problems caused by human error.The network communication protocol design scheme of the communication alarm management and maintenance system is proposed,and the Manage Communicate Control Protocol(MCCP)is adopted to communicate with the communication alarm host and the central server to ensure the network communication of the system.Efficiency and flexibility.A ModBus protocol control function table for transmitting data between the console and the central server is established,which conforms to industry standards.Using C#as the development language,the management software of the system is written in the Microsoft Visual Studio.NET development environment,the database table of the system is created on the Microsoft SQL Server platform,and the storage,modification and deletion of the system database are realized by using ADO.NET technology.Wait for the operation.The experimental platform of the communication alarm system was built,and the system management software,database and the network communication protocol part were tested.At present,the communication alarm management and maintenance system designed by this subject has been put into industrial production occasions,which has achieved the expected effect and high use value.
