Abstract


As the rapid development of the intelligent building, kinds of building intelligent subsystems grow in both number and scale. Integrating those isolated sub-systems could be the important content of researching work on building intelligent system integration technique.As the development of IT technology, a good solution for solving the problems of building intelligent system integration was proposed by applying the thinking of service oriented architecture SOA. At present, Web Services technology exists some disadvant- ages in respect of widely interoperability, adaptability, performance and so on although it is widely applicable in this field. In addition, bring inconvenience to user due to the subsystems interface dispersion and lack of organic integration.Based on that, this thesis presents a new way by combining a new SOA implementation technique WCF with Portal into the field of building intelligent system integration,in order to provide a new technical solution. It begins with a brief overview of the related contents of building intelligent system integration, and then some deeply research was done on the subjects of WCF, Portal, OPC and SSO. Based on the above work, a building intelligent system integration model based on WCF and Portal was presented. It mainly includes two aspects: WCF service design which mainly involves service function design and implementation framework design of service;Portal design which mainly involves interface integration design and Single Sign-On design. It follows the realization of this system integration model. In the aspect of system function level integration utilized by WCF,which mainly research on combing the WCF Service which supports AJAX with OPC technique to integrate field device system. In the aspect of system interface integration utilized by Portal, which mainly research on applying component portlet way to integrate application system portlet into Portal.Finally, the thesis studies another important aspect of the Portal- Single Sign-On, which is realized by using Liferay integrate CAS.The researching results of this subject are as follows. The prototype system of building intelligent system integration portal was developed, which shows that portlet successfully called WCF service and system function level integration was realized successfully, that means successfully integrating Portal with field device systems vertically and Portal with application information systems horizontally. In addition,the implementation of system interface level integration and Single Sign-On function were also successfully realized.Therefore, it proves that the technical route for building intelligent system integration based on WCF and Portal is feasible. That is where the innovation of the subject stands.Because of the information construction of intelligent building are still under developing and also limited by research level and condition, there are a lot of questions failed to be discussed deeply. But the technical solution proposed in the thesis and the successful development of the portal prototype system provide a kind of new feasible technical approach and reference for the further study of building intelligent system integration.
