Described herein are systems and methods for presenting building information. In overview, the technologies described herein provide relationships between Building Information Modeling (BIM) data (which includes building schematics defined in terms of standardized three dimensional models) and Building Management System (BMS) data (which includes data indicative of the operation of building components such as HVAC components and the like). Some embodiments use relationships between these forms of data thereby to assist technicians in identifying the physical location of particular pieces of equipment, for example in the context of performing inspections and/or maintenance. In some cases this includes the provision of 2D and/or 3D maps to portable devices, these maps including the location of equipment defined both in BIM and BMS data. In some cases, augmented reality technology is applied thereby to provide richer access to positional information.

A process includes mapping a data format in an object in a source schema to a data format in an object in a destination schema. The process includes defining an attribute mapping, defining a relation between the data format in the object in the source and the data format in the object in the destination, mapping the data format in the object in the source to the data format in the object in the destination, and converting the data format in the object in the source to another data format within the source. When the object in the source has no analog in destination, a foreign object is introduced into the destination, and when the object in the destination refers to one or more dependent objects, one or more instances of referred objects are generated according to a predefined policy in the mapping.

A method and system of generating a 3D geometric object model for a domain. The method includes: extracting basic geometric elements from an input source; converting the basic geometric elements into domain elements according to a domain model, wherein the domain elements preserve semantic information of their attributes and relationships defined by the domain model; and constructing a 3D geometric model, including 3D geometric objects, from the domain elements by geometric operators according to the domain model, wherein the 3D geometric objects maintain the semantic information of the domain elements, and the semantic information is allowed to be defined in a level of the objects.

Methods and apparatus are provided for a scalable user interface system. A user interface is divided into general reusable user interface components and application specific user interface components. Next profiles are created for user interfaces based upon server capabilities and client side device capabilities and reusable user interface components are built for use in multiple profiles. Defined user interface scalability strategies are executed at runtime to build a user interface description using the user interface components. In this way, a user interface can be built from a user interface description by apportioning the building of the user interface description between a server and a client side device using the profiles. At the server, user interface components stored in memory are used to build a first portion of the user interface description while a second portion of the user interface description is built at the client side device and is combined with the first portion received from the server.

A formal ontology includes multiple context elements to describe elements and their context within a system in the domain. The structure includes multiple role functions to describe the function of elements in the system, multiple types to describe values being provided by the elements in the system, and multiple states to describe states of the elements in the system, wherein the context elements, role functions, types, and states are selectable to provide a full description of the system.

A method includes receiving into a computer processor a building control subsystem design drawing, and identifying a plurality of objects in the building control subsystem design drawing by comparing the objects to a template of objects. The template of objects includes one or more of a representation of a shape, a color, and a texture. A physical relationship among the plurality of objects is determined, and a three dimensional representation of the plurality of objects is retrieved from a three dimensional device library. A three dimensional building control subsystem graphic is generated by mapping the three dimensional representation of the plurality of objects into a three dimensional user interface as a function of the physical relationship. The three dimensional user interface is animated and interactive to monitor and control a building subsystem.

A system for monitoring thermal comfort of a room. Sensor data concerning temperature, relative humidity, air speed and air flow may be collected from the room. The sensor data may provide thermal comfort level information about the room. The level information may be quantified in terms of a thermal comfort level index, such as a predicted mean vote, which can be used to identify one or more thermal comfort levels in the room with a numerical measure. The one or more levels may be portrayed as a visualization in terms of a 3D plot of temperature, humidity and air speed, several 2D plots, a dashboard, or other items. The visualization may easily enable one to see where setpoint adjustment is possible in a heating, ventilation and air conditioning system to save energy while maintaining thermal comfort acceptable to occupants in the room, whether during a heating season or a cooling season.
摘要:
An object oriented rule-based system and method that combines rule-based technology and object-oriented programming in order to provide an efficient approach for adding decision-making and inferencing capabilities to different applications. The rule-based system can include a RETE match algorithm, which can be modified to support pure object-based variable pattern matching. The LHS of a rule base can be compiled into several condition patterns, which includes a transformer integer array in order to record object variables positions. A RETE node can propagate tokens smoothly by asserting the object variable based on inheritance type hierarchy and the rules can be fired when the conditions are satisfied. The object oriented rule system can be utilized to add or remove rules at run time.
摘要:
An approach for building management, energy management and facility management systems and particularly to data models representing building and operational configurations of the systems. More particularly, the disclosure pertains to standard data models for representing these configurations and their transformation from non-standard form into a standard form defined by domain ontologies. The transformation is of ad hoc and disparate technical reference information into an ontologically correct and validated complex hierarchy with an associated set of integrated digital information.
