摘要:
Systems and methods are described that provide a Heat Flow Model (HFM) graph modeling methodology. Embodiments automatically translate formal HVAC system descriptions from a Building Information Model (BIM) into HFM graphs, and compile the graphs into executable FDD systems. During an engineering phase, a user interface is used to enter parameters, conditions, and switches not found in the BIM. During a runtime phase, real-time data from an HVAC control system is input to the generated FDD system (HFM graph) for fault detection and diagnosis.
摘要:
In order to reduce computation time and cost involved with detecting and diagnosing a fault in a system, simplified representations of components of the system are used to estimate valid intervals for state variables at the components. Generic failure rules are configured to compare the estimated valid intervals to related intervals for the same state variables, from either observations or propagations, for overlap. Failure output vectors are generated based on the comparison, and the failure output vectors are compared to diagnostic matrices to determine a source of the fault.

Methods and architectures are described that provide function block mobility between PLCs. Each PLC configured with Mobile Function Blocks (MFBs) may forward and execute MFBs from each other. To enable MFB mobility over a communication bus, each PLC having one or more configured MFBs requires a Communication Function Block (CFB) and an MFB directory data block. Each PLC maintains an MFB directory data block to store its MFB directory which is used when other PLCs send requests to check the availability of MFBs they need to run new tasks.

A method of controlling energy consumption in a building includes receiving occupancy data including at least one of occupant request data and occupant schedule data, receiving weather data including at least one of current weather measurement data and weather forecast data, generating an output control signal based on the occupancy data and the weather data, and transmitting the output control signal to a building automation system (BAS) of the building. The occupant request data includes a current request, and the occupant schedule data includes a predicted occupant schedule. The output control signal adjusts a building control device in a zone in the building.

A system and a method for routing an instant message which can refer to a Converged IP Messaging (CPM) message are provided. The instant message, for example, CPM message and the like, is sent to a plurality of terminals having the same user identification of the same user; in the case that the receiving party uses a plurality of terminals online simultaneously, the communication system such as a CPM system routes the instant message such as CPM message to a plurality of terminals respectively. Thereby, the problem of routing when forwarding an instant message such as a ‘one number more machines” CPM message can be solved, further, the transmission of messages in the communication system such as the CPM system is realized better, and improving the user experience.

The present invention provides a method and system for transmitting a large message mode CPM message. A MSRP link is created respectively between a CPM client at a sending end and a participating function entity at a source end, between the participating function entity at the source end and a CPM control function entity, and between the CPM control function entity and an inter-working function entity based on a media negotiation process before the CPM client transmits a large message mode CPM message to a non-CPM system receiver in a target group; then, the CPM client at the sending end sends the contents of the large message mode CPM message to the inter-working function entity through each created MSRP link sequentially; and the inter-working function entity sends the received contents of the large message mode CPM message to the non-CPM system receiver after performing protocol conversion on the received contents. The method and the system solve the problem that a large message mode CPM message cannot be transmitted to a group in the prior art and the user experience is improved.
