IBMS(Aggregation)? The integration of intelligent management system is defined as all the systems referred to, such as the intelligent library system, electrical and mechanical installations, lighting, HVAC, CCTV, audio system, announcement and fire alarm systems Fire, Door, IPTV, Network, VOIP & … We can control and monitor comprehensive software. The necessity of using the IBMS system The use of the integrated IBMS building intelligent management system, in addition to the 40% reduction in energy consumption in the library, will provide a great benefit to the user. In this system, the user can easily access from one point to the whole of his building section and, in addition to monitoring, issue control commands, or define control scenarios with specified time tables. It should be noted that the IBMS system is currently being implemented in all major & major libraries in the advanced countries. System Architecture (IBMS) The Intelligent Building Management System (IMS) will be designed and implemented at three main levels as follows: Supervisory Level Controller Level The Level Devices Field Management System (IBMS) The topology used in this system will be Hybrid. In this topology, in each floor, one or more control panels, including controllers & nets and system nodes, are predicted. The relationship between field equipment and sensors with conventional controllers in each floor will be standardized and all communication at the controller level and the higher levels will be based on the common standard protocol. Direct Digital Controls (DDCs): In this control, electronic signals are received through a computer and processed by controllers for direct control of systems. Stand-alone control: in which each system, individually and without connection to the building control system, has controllers that are generally of a great deal of complexity and can not be connected to standard control protocols or BMS systems. DDC control systems have many advantages over stand-alone controls, including more feedback, monitoring, and a centralized and integrated control system in DDC control systems.
