Abstract

Systems and methods provide a real-time data display and interface for a network device by loading a page in a browser (115), the page including an engine which is executed in the browser (120) and used to automatically load a definition file (125) from a remote source in response to content within the page. Widgets are instantiated for display in the interface, each making data requests (145) at intervals which are forwarded to one or more servers in communication with the network device. Requested data is received (160) and presented in the interface there by providing the user with dynamically updated data (165). An engine for driving such display comprises executable code configured to instantiate one or more widgets for rendering within the display of the real-time data interface. The engine further includes a reference to a definition file which defines prescribed parameters for one or more of the widgets.

Claims

1. A method for providing a real-time data display interface for a network device in communication with a building automation and control system, the method comprising:

loading a page in a browser configured for operation on the network device, the loaded page including an engine;

executing the engine in the browser;

using the engine to automatically load a definition file from a remote source in response to content within the loaded page;

instantiating a plurality of widgets in the interface and displaying them therein, each widget making data requests;

directing the data requests from each respective widget to the engine, wherein a first set of the plurality of widgets requests data for building control devices coupled to a first server of a building automation and control system and wherein a second set of the plurality of widgets requests data for building control devices coupled to a second server of the building automation and control system;

bundling by the engine the data requests from the first set of the plurality of widgets received during a predetermined interval into a first bundled request and bundling by the engine the data requests from the second set of the plurality of widgets received during the predetermined interval into a second bundled request;

forwarding by the engine the first bundled request to the first server and the second bundled request to the second server;

receiving the requested data in response to the first bundled request and the second bundled request; and

updating the interface with the received data;

wherein the definition file includes extensions to further code suitable for at least one of;

rendering the plurality of widgets, requesting data for the plurality of widgets to display within the interface and receiving data for the plurality of widgets to display in the interface.

2. The method of claim 1, including the additional steps of:

loading one or more software programs each being associated with the one or more widgets in response to the instantiating step; and

executing the software programs.

3. The method of claim 1, including the additional step of repeating the forwarding, receiving and updating steps at intervals prescribed by respective widgets in the interface.

4. The method of claim 1, including the additional step of directing data requests from at least one of the widgets directly to a particular server in communication with the network device.

5. The method of claim 1, wherein the forwarding and receiving steps are performed over a wireless communication link.

6. The method of claim 1, including the additional steps of:

testing for inputs provided through the interface at the network device; and

processing the inputs at one of the network device and the remote source.

7. The method of claim 6, wherein the input provided through the interface influences the appearance of the data displayed in the one or more widgets.

8. The method of claim 6, wherein the inputs are provided by a human user.

9. The method of claim 6, wherein the inputs are provided programmatically by the network device itself.

10. The method of claim 1, wherein the page loaded in the browser is a web page.

11. The method of claim 10, wherein the web page includes a body portion that consists essentially of the engine.

12. The method of claim 1, wherein each widget is generated dynamically in response to the definition file at the remote source.

13. The method of claim 1, wherein the engine is on the order of about 400 Kilobytes in size.

14. The method of claim 1, wherein updating the interface with the received data includes updating the interface independently of updating the page in the browser.

15. An apparatus for providing a real-time data display interface for a network device in communication with a building automation and control system, the apparatus comprising:

a processor and a memory;

a browser executable by the processor and memory and operable to download a page in prescribed format, wherein the page includes an engine executable by the processor and executable code to instantiate a plurality of widgets for rendering within the real-time data display interface;

a reference to a definition file which defines prescribed parameters for the plurality of widgets; and

a first server coupled to building control devices and a second server coupled to building control devices, the first server and second server further coupled to the building automation and control system;

wherein the plurality of widgets are operable to direct data requests to the engine, the data requests including requests by a first set of the plurality of widgets for data from building control devices coupled to the first server and requests by a second set of the plurality of widgets for data from building control devices coupled to the second server, and wherein the engine is operable to;

bundle the data requests from the first set of the plurality of widgets received during a predetermined interval into a first bundled request and bundle the data requests from the second set of the plurality of widgets received during the predetermined interval into a second bundled request,

forward the first bundled request to the first server and the second bundled request to the second server,

receive the requested data in response to the first bundled request and the second bundled request, and

update the interface with the received data; and

wherein the definition file includes extensions to further code suitable for at least one of;

rendering the plurality of widgets, requesting data for the plurality of widgets to display within the interface and receiving data for the plurality of widgets to display in the interface.

16. The apparatus of claim 15, wherein the page is in an HTML format.

17. The apparatus of claim 15, wherein the definition file is located at a source remote from the network device.

18. A computer-readable storage medium having computer executable instructions stored thereon that when executed by one or more processors perform a method for providing a real-time data display interface for a network device in communication with a building automation and control system, the method comprising:

loading a page in a browser configured for operation on the network device, the loaded page including an engine;

executing the engine in the browser;

using the engine to automatically load a definition file from a remote source in response to content within the loaded page;

instantiating a plurality of widgets in the interface and displaying them therein, each widget making data requests;

directing the data requests from each respective widget to the engine, wherein a first set of the plurality of widgets requests data for building control devices coupled to a first server of the building automation and control system and wherein a second set of the plurality of widgets requests data for building control devices coupled to a second server of the building automation and control system;

bundling by the engine the data requests from the first set of the plurality of widgets received during a predetermined interval into a first bundled request and bundling by the engine the data requests from the second set of the plurality of widgets received during the predetermined interval into a second bundled request;
