The Design And Development Of The Intelligent Building System Integration Based On Niagara Technology

System integration(SI) of intelligent building(IB) have been a necessarypart of IB field.But nowadays in China, different types of electromechanical equipment and communicationprotocols used in IB systems, made the SI difficulty and lowness. The article is to solve theproblem: traditional integration software platform can not be widely used and the programwork is heavy. Use the Niagara SI technology based on Baja standard, to develop a IBintegrationsystem(IS)appliedinthethirdtermengineeringofainternationalsciencepark.Firstly, introduced the integration types of IB system and the recent researches in IB SI,pointedthemeaningofthearticle.ResearchedBajastandard,Niagaratechnology,Javavirtualmachine and realization of SI. Secondly, accord to the design principal of SI, combined theengineering design requirement, give the whole design method, construct the SI model, anddevide SI layers. Thirdly, describe all subsystems and communication design of integrationplatform. Accord to the communication protocol offered by electromechanical equipmentsupplier, test the communication of subsystem; on the Niagara FrameworkTM softwareplatform,useJbuilder9.0todevelopthecommunicationinterfaceprogramandrealizethedatatransferation between SI and subsystems. Fourthly, discribe the realization of functionintegration in subsystems from longitude and landscape orientation function integrationdistinctly. Give the logic picture, program design flow and related linkage response supportprograme of subsystem function integration. Fifthly, embed the web technology based oninternet to integration platform, to realize the remote visit of IS. Accord to the subsystemsqualification and user requirement, design the user interface, user account allocation and uservisitright.Finally,testthewholesystem,givethetestpageandanalysedthetestresult.The article design the IB IS on Niagara FrameworkTM platform, fulfill the integration ofmulti electronic subsystem. The test result showed that, the designed system run stably andputintoapplication.
