US 2025/0085671 A1 · BUILDING CONTROL SYSTEM WITH BROKERING ARCHITECTURE

Abstract

A distributed control system is provided by a brokering architecture. Message brokers running within multiple compute environments coordinate communication and data storage for control applications. Control applications run in one compute environment send the results to the message broker which may store the data for future calculations and/or send the data to a remote data base. Control applications may be state-less and store all information in the message brokers. Data from one environment may be sent over a message bus to other environments to be used as inputs to calculations. The distributed control system is used to provide responsive control to various building equipment.

Dependent claims

A system for controlling and monitoring a building, the system comprising:

one or more input-output modules configured to send and receive messages over a network;
and
one or more memory devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
operating a first isolated compute environment to perform a first set of additional operations comprising:
receiving a first message comprising a current value of a variable of the building from the one or more input-output modules;
storing the current value of the variable;
and
sending a second message in response to a request for the current value of the variable;
and
operating a second isolated compute environment to perform a second set of additional operations comprising:
sending the request for the current value of the variable;
and
performing a control calculation to determine a result based on the current value of the variable.

A system for controlling and monitoring a building, the system comprising:

one or more input-output modules configured to send and receive messages over a network;
and
one or more memory devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving a first message comprising a current value of a variable of the building;
receiving a second message comprising a previous result of a control calculation;
performing the control calculation to determine a result based on the current value of the variable and the previous result;
sending a third message comprising the result to a storage device logically isolated from the one or more memory devices;
and
sending a fourth message comprising the result to at least one input-output module of the one or more input-output modules to affect the building,
wherein the result saved in the storage device logically isolated from the one or more memory devices is used in a subsequent control calculation.
