Abstract

A system for controlling building equipment devices includes a processing circuit comprising a processor and memory storing instructions executed by the processor. The system is configured to generate a first combination profile indicating a number of active devices within each of one or more device groups according to a first combination of the building equipment devices, and generate a second combination profile indicating a number of active devices within each of the one or more device groups according to a second combination of the building equipment devices. The system is also configured to compare the first combination profile against the second combination profile to determine whether the first combination is redundant with the second combination, generate control decisions for the building equipment devices based on whether the first combination is redundant with the second combination, and operate the building equipment devices in accordance with the control decisions.

First claim

What is claimed is:

1. A system for controlling building equipment devices, the system comprising:
a processing circuit comprising a processor and memory storing instructions executed by the processor, the processing circuit configured to:
generate a first combination profile indicating a number of active devices within each of one or more device groups according to a first combination of the building equipment devices;
generate a second combination profile indicating a number of active devices within each of the one or more device groups according to a second combination of the building equipment devices;
compare the first combination profile against the second combination profile to determine whether the first combination is redundant with the second combination, wherein in response to determining the first combination and the second combination are redundant, the system is further configured to (i) store the first combination profile in a database and eliminate the second combination or (ii) delete the second combination from the database;
generate control decisions for the building equipment devices based on whether the first combination is redundant with the second combination; and
operate the building equipment devices in accordance with the control decisions.

2. The system of claim 1 , wherein in response to determining the first combination and the second combination are not redundant, the system is further configured to store the first combination profile and the second combination profile in a database.

3. The system of claim 2 , wherein the system is further configured to:
generate a third combination profile indicating a number of active devices within each of the one or more device groups according to a third combination of the building equipment devices; and
compare the third combination profile against existing combination profiles stored in the database.

4. The system of claim 3 , where in response to determining the third combination and existing combinations stored in the database are not redundant, the system is further configured to store the third combination profile in the database.

5. The system of claim 1 , wherein the system is further configured to:
generate a database including a plurality of combinations of the building equipment devices indicating a number of active devices within each of the one or more device groups according to the plurality of combinations of the building equipment devices; and
save a first combination profile in the database indicating a number of active devices within each of the one or more device groups according to a first combination of the building equipment devices.

6. A system for controlling building equipment devices, the system comprising:
a processing circuit comprising a processor and memory storing instructions executed by the processor, the processing circuit configured to:
categorize a first building equipment device and a second building equipment device into either a single device group or into different device groups by comparing a first set of device attributes of the first building equipment device to a second set of device attributes of the second building equipment device, wherein the system is further configured to:
determine the first set of device attributes of the first building equipment device and the second set of device attributes of the second building equipment device are similar based on an error or difference between the first set of device attributes and the second set of device attributes being below a threshold; and
in response to the first set of device attributes of the first building equipment device and the second set of device attributes of the second building equipment device being similar, categorize the first building equipment device and the second building equipment device into the single device group;

generate control decisions for the first building equipment device and the second building equipment device based on whether the first building equipment device and the second building equipment device are categorized into the single device group or into the different device groups; and
operate the first building equipment device and the second building equipment device according to the control decisions.

7. The system of claim 6 , wherein the system is further configured to:
obtain a first set of equipment performance data characterizing an operating performance of the first building equipment device and a second set of equipment performance data characterizing an operating performance of the second building equipment device; and
generate the first set of device attributes of the first building equipment device based on the first set of equipment performance data and the second set of device attributes of the second building equipment device based on the second set of equipment performance data.

8. The system of claim 6 , wherein the first set of device attributes of the first building equipment device includes a first equipment model coefficient and the second set of device attributes of the second building equipment device includes a second equipment model coefficient.

9. The system of claim 6 , wherein the first set of device attributes of the first building equipment device includes a first device parameter and the second set of device attributes of the second building equipment device includes a second device parameter.

10. The system of claim 6 , wherein in response to the first set of device attributes of the first building equipment device and the second set of device attributes of the second device not being similar, the system is further configured to categorize the first building equipment device and the second building equipment device into the different device groups.

11. A method for controlling building equipment devices, comprising:
generating a first combination profile indicating a number of active devices within each of one or more device groups according to a first combination of the building equipment devices;
generating a second combination profile indicating a number of active devices within each of the one or more device groups according to a second combination of the building equipment devices;
comparing the first combination profile against the second combination profile to determine whether the first combination is redundant with the second combination, wherein in response to determining the first combination and the second combination are redundant, the method further comprises storing the first combination profile in a database and eliminating the second combination;
generating control decisions for the building equipment devices based on whether the first combination is redundant with the second combination; and
operating the building equipment devices in accordance with the control decisions.

12. The method of claim 11 , wherein in response to determining the first combination and the second combination are not redundant, the method further comprises storing the first combination profile and the second combination profile in a database.

13. The method of claim 11 , further comprising:
generating a third combination profile indicating a number of active devices within each of the one or more device groups according to a third combination of the building equipment devices; and
comparing the third combination profile against existing profiles stored in a database.

14. The method of claim 13 , where in response to determining the third combination and existing combinations stored in the database are not redundant, the method further comprises storing the third combination profile in the
