Abstract

An equipment controller in a building management system (BMS) includes a feature detector and a dynamic point list generator. The feature detector is configured to receive sensor input from a sensor and determine a set of features available to the equipment controller based on the sensor input. The dynamic point list generator is configured to determine unavailable features based on the set of available features and identify one or more points in a complete point list associated with the set of unavailable features. The dynamic point list generator is configured to generate a dynamic point list by removing the identified points from the complete point list and expose the dynamic point list to a BMS controller communicably connected to the equipment controller.

First claim

What is claimed is:

1. An equipment controller in a building management system (BMS), the equipment controller comprising:
one or more circuits configured to:
receive sensor input from a sensor;
determine, based on the sensor input, a set of features available to the equipment controller;
determine, based on the set of available features, a set of unavailable features;
identify, in a complete point list, one or more points associated with the set of unavailable features;
generate a dynamic point list by removing the one or more points associated with the set of unavailable features from the complete point list; and
expose the dynamic point list to a BMS controller communicably connected to the equipment controller.

2. The equipment controller of claim 1 , the one or more circuits further configured to:
provide a user interface to a user device;
receive user input from the user device via the user interface; and
determine, based on the user input, a set of selected applications;
determine, based on the set of selected applications, a set of unselected applications;
identify, in the dynamic point list, one or more points associated with the set of unselected applications; and
remove, from the dynamic point list, the identified points associated with the set of unselected applications.

3. The equipment controller of claim 1 , the one or more circuits further configured to:
receive the sensor input and calculate a reliability confidence level associated with the sensor input;
determine whether the reliability confidence level exceeds a reliability threshold; and
in response to a determination that the reliability confidence level exceeds the reliability threshold, identify one or more points associated with the sensor input and remove the identified points from the dynamic point list.

4. The equipment controller of claim 3 , the one or more circuits further configured to:
calculate the reliability confidence level by comparing the sensor input to historical data.

5. The equipment controller of claim 4 , the one or more circuits further configured to:
detect a second set of applications based on input from the BMS controller;
determine, based on the second set of applications, a second set of unselected applications;
identify, in the dynamic point list, one or more points associated with the second set of unselected applications; and
remove, from the dynamic point list, the identified points associated with the second set of unselected applications.

6. The equipment controller of claim 1 , the one or more circuits further configured to:
receive a set of applications based on input from the BMS controller;
determine, based on the set of applications, a set of unselected applications;
identify, in the dynamic point list, one or more points associated with the set of unselected applications; and
remove, from the dynamic point list, the identified points associated with the set of unselected applications.

7. A method for dynamically adjusting points exposed by an equipment controller in a building management system (BMS), the method comprising:
receiving, at the equipment controller, a sensor input from a sensor;
detecting, based on the sensor input, a set of features available to the equipment controller;
determining, based on the set of available features, a set of unavailable features;
identifying, in a complete point list, one or more points associated with the set of unavailable features;
generating a dynamic point list by removing the one or more points associated with the set of unavailable features from the complete point list; and
exposing the dynamic point list to a BMS controller in the BMS.

8. The method of claim 7 , further comprising:
receiving a user input from a user device;
detecting, based on the user input, a set of selected applications;
determining, based on the set of selected applications, a set of unselected applications;
identifying, in the dynamic point list, one or more points associated with the set of unselected applications; and
removing, from the dynamic point list, the one or more points associated with the set of unselected applications.

9. The method of claim 8 , further comprising:
providing a user interface to the user device; and
receiving a selection, via the user interface, of a set of applications capable of being executed by the equipment controller.

10. The method of claim 7 , further comprising:
calculating a reliability confidence level associated with the sensor input;
determining whether the reliability confidence level exceeds a reliability threshold; and
in response to a determination that the reliability confidence level exceeds the reliability threshold, identifying one or more points in the dynamic point list associated with the sensor input and removing the one or more points in the dynamic point list associated with the sensor input from the dynamic point list.

11. The method of claim 10 , wherein calculating the reliability confidence level comprises comparing the sensor input to historical data.

12. The method of claim 11 , further comprising:
receiving a BMS input from the BMS controller;
detecting, based on the BMS input, a second set of applications;
determining, based on the second set of applications, a second set of unselected applications;
identifying, in the dynamic point list, one or more points associated with the second set of unselected applications; and
removing, from the dynamic point list, the one or more points associated with the second set of unselected applications.

13. The method of claim 7 , further comprising:
receiving a BMS input from the BMS controller;
detecting, based on the BMS input, a set of selected applications;
determining, based on the set of selected applications, a set of unselected applications;
identifying, in the dynamic point list, one or more points associated with the set of unselected applications; and
removing, from the dynamic point list, the one or more points associated with the set of unselected applications.

14. A method for dynamically adjusting points exposed by a controller in a building management system (BMS), the method comprising:
receiving, at the controller, a sensor input from a sensor;
detecting, based on the sensor input, a set of features available to the controller;
determining, based on the set of available features, a set of unavailable features;
identifying, in a complete point list, one or more points associated with the set of unavailable features;
generating a dynamic point list by removing the one or more points associated with the set of unavailable features from the complete point list; and
exposing the dynamic point list to the BMS.

15. The method of claim 14 , further comprising:
receiving a user input from a user device;
detecting, based on the user input, a set of selected applications;
determining, based on the set of selected applications, a set of unselected applications;
