The Design And Implementation Of Power Monitoring System Based On CORBA

With the advent of the network time,the computer network rapid development,the network infrastructure is consummating unceasingly,the network performance improvement,the price drops.The use of social networking services may become more urgent.Using the network realization long-distance monitoring and the management will facilitate the staff,reduce labor intensity,reduce the cost of labor, raise working efficiency, save social resources,creat public wealth.CORBA is organized by the OMG to develop a standard object-oriented application system of norms.The core of CORBA is a standard language,interface and agreement.The CORBA supports isomerism distributed application program interoperability and is independent in the platform and the programming language object entrusts with heavy responsibility.This paper analys the distributed monitoring system,refers to the traditional monitoring system design,combines with the demand of power monitoring system.In order to achieve the purpose of distributed monitoring,the monitoring system is designed to be three-tier:Equipment System level,Operation System level,Workstation level. Equipment System level uses agreement to adaptive module,in order to shield the difference between equipments;Operation System level is divided into a number of services by business,which collects the data from equipment system level and talks with workstation level;Workstation level is a operating front to achieve interaction with user,which is built by modules.Calling CORBA to achieve information exchange between modules and services,modules/services and field device ,or internal services, and emphatically design data service,naming service,security service,SCADA module, remote monitoring management module.Besides,the power monitoring system uses Hot Standby,fault-tolerant service system to guarantee a fault-tolerant operation.
