Distributed device network-based control system with decoupled intelligence for smart windows
A distributed device control system is provided. The system includes a plurality of windows, each window of the plurality of windows having at least one electrochromic window, a voltage or current driver for the at least one electrochromic window, and a first control system local to the window. The system includes a plurality of window controllers, each window controller configured to couple to one or more of the plurality of windows and having a second control system, for the one or more of the plurality of windows, local to the window controller. The system includes a command and communication device configured to couple to each of the plurality of window controllers, configured to couple to a network, and having a third control system, for the plurality of windows, wherein control of the plurality of windows is distributed across the plurality of windows, the plurality of window controllers, the command and communication device, and a portion of the network.
1. A method for controlling windows, comprising:
controlling, from first control systems of a plurality of windows, transmissivity of the plurality of windows, based on sensor information from sensors of the windows, direction from second control systems of a plurality of window controllers coupled to the plurality of windows, or direction from a third control system of a command and communication device coupled to the plurality of window controllers;
directing, from the second control systems of the plurality of window controllers, in cooperation with the plurality of windows, the transmissivity of the plurality of windows; and
directing, from the third control system of the command and communication device, in cooperation with the plurality of window controllers and the plurality of windows, the transmissivity of the plurality of windows, based on the sensor information from the sensors of the windows or information obtained from a network to which the command and communication device is coupled, wherein a server coupled to the network gathers operating information from smart windows in a plurality of buildings and develops window operating profiles or window operating modes, and wherein the control of the windows is based in part on the window operating profiles or window operating modes developed in the server.
2. The method of claim 1 , wherein:
the third control system includes cloud-based adaptive algorithms; and
control and direction for the transmissivity of the plurality of windows is distributed and movable among the command and communication device, the plurality of window controllers, and the plurality of windows.
3. The method of claim 1 , further comprising:
operating the plurality of windows in a continuous manner despite a network outage, via application of the first control systems, the second control systems or the third control system.
4. The method of claim 1 , wherein:
the directing from the third control system is based on weather information gathered from the network; and
the sensor information includes sensor information from light, image, sound or temperature sensors of the window.
5. The method of claim 1 , further comprising:
operating each window of the plurality of windows in an individual manner in accordance with the first control system of the window;
overriding the first control system of each of the plurality of windows, from the plurality of window controllers, to control the plurality of windows in accordance with the second control system of each of the plurality of window controllers; and
overriding the second control system of each of the plurality of window controllers, from the command and communication device, to control the plurality of windows in accordance with the third control system of the command and communication device.
6. The method of claim 1 , further comprising:
overriding one or more of the first control systems, the second control systems and the third control system, to control the plurality of windows in accordance with a request received at the command and communication device from the network.
7. The method of claim 1 , further comprising:
gathering weather information from the network and control the plurality of windows based at least in part on the weather information.
8. The method of claim 1 , further comprising:
overriding, through at least one of the second control systems, the first control system of at least one of the plurality of windows to control the at least one of the plurality of windows.
9. The method of claim 1 , further comprising:
overriding, through the third control system, the first control system of at least one of the plurality of windows and the second control system of at least one of the plurality of window controllers to control the at least one of the plurality of windows.
10. The method of claim 1 , further comprising:
at least one of the plurality of windows and the first control system thereof configured to receive first user input at the window;
at least one of the plurality of window controllers and the second control system thereof configured to receive second user input at the window controller; and
the command and communication device and the third control system configured to receive third user input at the command and communication device and receive fourth user input from the network.
11. The method of claim 1 , further comprising:
cooperating, by the first control systems, the second control systems and the third control system to control the plurality of windows based on a combination of sensor input from the windows, user input, and information from the network.
12. The method of claim 1 , further comprising:
cooperating, by the first control systems, the second control systems and the third control system to control temperature of an interior of a building by controlling transmissivity of the plurality of windows.
