Abstract

A framework for centrally controlling a plurality of building automation systems. The architecture and method automates a plurality of existing and new building automation systems comprising access control, HVAC, fire safety etc. in such a way that the plurality of building automation systems can be monitored and controlled from a central dashboard. The central dashboard effectively monitors, takes right decisions and remotely controls the buildings across the globe from a centralized location.

Claims

1. An architecture for centrally controlling a plurality of building automation systems, the architecture comprises:

a data access layer for extracting data from the plurality of building automation systems;

determining priority of the data;

upon determination of the priority below a predetermined priority level, storing the data in a standard format in a database;

a business layer for processing the stored data and generating a result based on an user request;

a service layer for representing the standard format data and the result in an OPC UA format; and

an user interface layer in connection with the service layer to access the data and the result represented in the OPC UA format to centrally control the plurality of building automation systems.

2. The architecture as claimed in claim 1, wherein upon determination of the priority above the predetermined priority level,

the data access layer transfers the data to the service layer without storing the data in the database;

the service layer represents the data in the OPC UA format; and

the user interface layer accesses the data represented in OPC UA format to centrally control the plurality of building automation systems.

3. The architecture as claimed in claim 1, wherein the data access layer provides for accessing the standard format data from the database.

4. The architecture as claimed in claim 1, wherein the data extracted from the plurality of building automation systems are in different formats.

5. The architecture as claimed in claim 1, wherein the business layer comprises an access control unit configured to authenticate the user access to the database.

6. The architecture as claimed in claim 1, wherein the result generated by the business layer comprises at least one of a report and a performance value of the plurality of building automation systems.

7. The architecture as claimed in claim 1, wherein the service layer comprises a System Application and Products (SAP) connector to connect the building automation system with an enterprise solution.

8. The architecture as claimed in claim 1, wherein the user interface layer is configured to display at least one of:

the report generated using the data stored in the database;

an alarm signal;

the performance value;

energy consumed by the plurality of buildings; and

video recording of the plurality of buildings.

9. A method for centrally controlling a plurality of building automation systems, the method comprising acts of:

extracting data from the plurality of building automation systems and storing the data in a standard format in a database;

determining priority of the data and upon determination of the priority below a predetermined priority level, storing the data in a standard format in a database;

processing the stored data and generating a result based on an user request;

representing the standard format data and the result in an OPC UA format; and

accessing the data and the result as represented in the OPC UA format to centrally control the plurality of building automation systems.

10. The method as claimed in claim 9, wherein upon determination of the priority above the predetermined priority level,

transferring the data to the service layer without storing the data in the database;

representing the data in the OPC UA format; and

accessing the data represented in OPC UA format to centrally control the plurality of building automation systems.

11. The method as claimed in claim 9, wherein the access to the stored data is allowed upon authentication of the user.

12. The method as claimed in claim 9, wherein the result generated comprises at least one of a report and a performance value of the plurality of building automation systems.
