Abstract

Claims (61)

1. A building management system comprising:

building equipment configured to provide raw data samples of a data point;

a data collector configured to collect the raw data samples from the building equipment and generate a raw data timeseries comprising a plurality of the raw data samples;

a timeseries service configured to generate one or more optimized data timeseries from the raw data timeseries;

a timeseries database configured to store a plurality of timeseries associated with the data point, the plurality of timeseries comprising the raw data timeseries and the one or more optimized data timeseries; and

a dashboard layout generator configured to identify each of the timeseries associated with the data point and to generate a framework-agnostic dashboard layout description capable of being rendered by multiple different rendering frameworks to visualize each of the identified timeseries;

wherein the timeseries service comprises a virtual point calculator configured to:

create a virtual data point representing a non-measured variable;

calculate data values for a plurality of samples of the virtual data point as a function of the raw data samples;

generate a virtual point timeseries comprising the plurality of samples of the virtual data point; and

store the virtual point timeseries in the timeseries database as one of the optimized data timeseries.

2. The building management system of claim 1 , wherein the timeseries service comprises a sample aggregator configured to:

automatically generate a data rollup timeseries comprising a plurality of aggregated data samples by aggregating the raw data samples as the raw data samples are collected from the building equipment; and

store the data rollup timeseries in the timeseries database as one of the optimized data timeseries.

3. The building management system of claim 1 , wherein the timeseries service comprises a scalable rules engine configured to:

detect faults by applying fault detection rules to at least one of the raw data timeseries and the optimized data timeseries;

generate a fault detection timeseries comprising a plurality of fault detection data samples, each of the fault detection data samples having a timestamp and a data value indicating whether a fault is detected at the timestamp; and

store the fault detection timeseries in the timeseries database as one of the optimized data timeseries.

4. The building management system of claim 1 , wherein the dashboard layout generator is configured to generate the framework-agnostic dashboard layout description by:

defining a dashboard layout as a grid comprising multiple intersecting rows and columns;

identifying an intersection of the multiple rows and columns as a widget location; and

generating widget properties that define a widget at the identified widget location, the widget properties identifying one or more of the plurality of timeseries.

5. The building management system of claim 1 , wherein the dashboard layout generator is configured to generate the framework-agnostic dashboard layout description by:

defining a dashboard layout as an array of objects comprising one or more row objects and one or more column objects;

specifying a location of a widget object within the array; and

storing widget properties within the widget object, the widget properties identifying one or more of the plurality of timeseries.

6. The building management system of claim 5 , wherein:

the one or more column objects are nested within the one or more row objects; and

each of the column objects comprises a widget object nested within the column object.

7. The building management system of claim 5 , wherein:

the one or more row objects are nested within the one or more column objects; and

each of the row objects comprises a widget object nested within the row object.

8. The building management system of claim 5 , wherein the widget properties identify an application program interface that drives the widget object.

9. The building management system of claim 5 , wherein the widget properties identify a location of each of the plurality of timeseries in the timeseries database.

10. The building management system of claim 1 , wherein the dashboard layout description comprises a plurality of top level properties that apply to an entirety of a dashboard layout, the top level properties comprising at least one of:

a name of the dashboard layout;

an indication of whether the dashboard layout is collapsible;

an indication of whether the dashboard layout is maximizable; and

an indication of whether the dashboard layout is editable.

11. A building management system comprising:

a timeseries database configured to store multiple timeseries associated with a data point, each of the timeseries comprising a plurality of data samples; and

a dashboard layout generator configured to access the timeseries database to identify each of the timeseries associated with the data point and to generate a framework-agnostic dashboard layout description capable of being rendered by multiple different rendering frameworks to visualize each of the identified timeseries;

wherein the multiple timeseries stored in the timeseries database comprise a raw data timeseries comprising a plurality of raw data samples and one or more optimized data timeseries generated by processing the raw data timeseries;

further comprising a virtual point calculator configured to:

create a virtual data point representing a non-measured variable;

calculate data values for a plurality of samples of the virtual data point as a function of the raw data samples;

generate a virtual point timeseries comprising the plurality of samples of the virtual data point; and

store the virtual point timeseries in the timeseries database as one of the optimized data timeseries.

12. The building management system of claim 11 , further comprising a sample aggregator configured to: automatically generate a data rollup timeseries comprising a plurality of aggregated data samples by aggregating the raw data samples as the raw data samples are collected; and store the data rollup timeseries in the timeseries database as one of the optimized data timeseries.

13. The building management system of claim 11 , further comprising a scalable rules engine configured to: detect faults by applying fault detection rules to at least one of the raw data timeseries and the optimized data timeseries; generate a fault detection timeseries comprising a plurality of fault detection data samples, each of the fault detection data samples having a timestamp and a data value indicating whether a fault is detected at the timestamp; and store the fault detection timeseries in the timeseries database as one of the optimized data timeseries.

14. The building management system of claim 11 , wherein the dashboard layout generator is configured to generate the framework-agnostic dashboard layout description by:

defining a dashboard layout as an array of objects comprising one or more row objects and one or more column objects;

specifying a location of a widget object within the array; and

storing widget properties within the widget object, the widget properties identifying one or more of the multiple timeseries.

15. The building management system of claim 14 , wherein:

the one or more column objects are nested within the one or more row objects; and

each of the column objects comprises a widget object nested within the column object.

16. The building management system of claim 14 , wherein:

the one or more row objects are nested within the one or more column objects; and

each of the row objects comprises a widget object nested within the row object.

17. The building management system of claim 14 , wherein the widget properties identify at least one of an application program interface that drives the widget object and a location of each of the multiple timeseries in the timeseries database.
