Self-healing control network for building automation systems
First Claim
1. A self-healing automating building control system, the system comprising:
- a first controller configured to control a building environment according to wirelessly receiving data associated with a sensed environmental condition; and
a second controller configured to control the building environment according to wirelessly receiving data associated with a failure of a communications path between the first controller and a source of the data,wherein control of the building environment switches from the controller to the second controller in conjunction with or response to a switch in the communications path.

Abstract
In building automation architectures, components may be associated through physical communications paths and at a different level through building automation applications. Building automation applications implement control processes for a building function. Due to changing needs, such as a failure of a physical communications path or the addition or removal of components, the building automation application may be more appropriately performed in a different device. By dynamically positioning or determining a processor for implementing a building automation application, an architecture or network may more optimally control building functions, such as by requiring less user input, more rapid response and/or avoiding building function failures.

6. A method for automating building control, the method comprising:
-
automatically controlling a building environment with a building automation application implemented on a first controller according to a wireless communication via a communications path with a second controller; detecting a failure of a communications path between the first controller and second controller using a time-out mechanism that provides a time period for an expected communication; and switching the building automation application to a third controller in response to the failure of the communications path between the first controller and second controller, the third controller automatically controlling the building environment based upon a communication with the second controller. - View Dependent Claims (7, 8, 9)
