Abstract

A universal web-based interface is provided for remotely accessing any building management system capable of communicating with an external computer. During an initiation routine, the software providing the interface automatically determines what objects are connected to the building management system, and then creates data structures and web pages suitable for storing and displaying those objects. The software comprises a driver that provides a communication interface, and a communications protocol-independent generic portion.

Claims

1. A method by which software executing on an interface computer provides a web-based interface for a building management system connected to a plurality of objects, wherein the building management system is capable of communicating with an external computer using a communications protocol, the method comprising the steps of:

selecting a communications driver based on the communications protocol employed by the building management system;

employing the selected driver to establish communications between the interface computer and the building management system, and

determining what objects are connected to the building management system.

2. The method of claim 1, wherein the step of selecting a communications driver comprises receiving user input identifying the building management system and selecting the appropriate driver for that building management system.

3. The method of claim 1, wherein the step of selecting a communications driver comprises determining the identity of the building management system and selecting the appropriate driver for that building management system.

4. The method of claim 1, wherein the driver comprises a translation layer and a driver layer.

5. The method of claim 1, wherein the step of determining what objects are connected to a building management system comprises the steps of interrogating the building management system to determine what devices are connected to the building management system and interrogating the building management system to determine what objects are connected to the building management system.

6. The method of claim 1, further comprising the step of creating a database to store data relating to the objects connected to the building management system.

7. The method of claim 1, wherein the interface computer is connected to more than one building management system, and wherein the software executing on the interface computer is providing a web-based interface for those building management systems.

8. An interface computer that provides an web-based interface for a building management system, wherein the building management system is capable of communicating with an external computer using a communications protocol, the interface computer comprising a data storage device containing executable code that performs the following steps:

selecting a communications driver based on the communications protocol employed by the building management system;

employing the selected driver to establish communications between the interface computer and the building management system, and

determining what objects are connected to the building management system.

9. The interface computer of claim 8, wherein the step of selecting a communications driver comprises receiving user input identifying the building management system and selecting the appropriate driver for that building management system.

10. The interface computer of claim 8, wherein the step of selecting a communications driver comprises determining the identity of the building management system and selecting the appropriate driver for that building management system.

11. The interface computer of claim 8, wherein the driver comprises a translation layer and a driver layer.

12. The interface computer of claim 8, wherein the step of determining what objects are connected to a building management system comprises the steps of interrogating the building management system to determine what devices are connected to the building management system and interrogating the building management system to determine what objects are connected to the building management system.

13. The interface computer of claim 8, wherein the steps performed by the executable code also comprise the step of creating a database to store data relating to the objects connected to the building management system.

14. The interface computer of claim 8, wherein the interface computer is connected to more than one building management system, and wherein the executable code provides a web-based interface for all of those building management systems.

15. A system for communicating with a building management system over the World Wide Web comprising:

an interface computer in communication with both the building management system and the Internet;

wherein the interface computer executes software comprising a generic portion and a portion tailored to the building management system, wherein the operation of the generic portion is independent of the communications protocol employed by the building management system, and the portion tailored to the building management system provides an interface between the generic layer and the building management system.

16. The system for communicating with a building management system of claim 15, wherein the generic portion of the software comprises a user-interface layer, a server layer, and a database layer.

17. The system for communicating with a building management system of claim 15, wherein the portion of the software tailored to the building management system comprises a translation layer and a driver layer.

18. The system for communicating with a building management system of claim 16, wherein the user interface layer dynamically generates web pages by means of a servlet or applet.

19. The system for communicating with a building management system of claim 15, wherein the generic portion of the software is capable of sending e-mail notifications of alarm conditions.

20. The system for communicating with a building management system of claim 15, wherein the interface computer is connected to more than one building management system, and wherein the software executing on the interface computer provides a web-based interface for all of those building management systems.
