Abstract

A wireless sensor network at a monitored location can be configured to generate sensor channel(s) of data to assess operational conditions at the monitored location. Inputs based on the sensor channel(s) of data are provided to a host system for analysis of a demand to one or more resources at the monitored location. Response messages can be generated based on the demand analysis and transmitted to actuator(s) at the monitored location to effect an adjustment to the operational conditions.

First claim

What is claimed is:

1. A wireless node network, comprising:
a gateway device installed at a monitored location, the gateway device having a network connection to a host system remote from the monitored location;
a plurality of wireless nodes installed at the monitored location, each of the plurality of wireless nodes configured for communication with the gateway device via wireless communication, the plurality of wireless nodes including,
a first wireless node configured to connect to a sensor device via a first wired interface connection, the first wireless node configured to transmit sensor data based on measurements using the sensor device to the gateway device for delivery to the host system, and
a second wireless node having a wireless module and a control module that are connected by a wired communication interface that facilitates communication between a first controller in the wireless module and a second controller in the control module, the wireless module further including a wireless transceiver that receives a control message from the gateway device via wireless communication, the control message based on an analysis by the host system of the transmitted sensor data to assess a demand at the monitored location of a resource, the control module further including an actuator configured to connect to a resource consumption control device via a second wired interface connection, the actuator configured to generate a control signal for transmission to the resource consumption control device via the second wired interface connection to adjust a consumption of the resource using the resource consumption control device at the monitored location, the control signal generated in response to control information, which is based on the control message, that is transmitted from the first controller to the second controller via the wired communication interface.

2. The wireless node network of claim 1 , wherein the resource is a utility service.

3. The wireless node network of claim 1 , wherein the wireless communication is based on the IEEE 802.15.4 protocol.

4. The wireless node network of claim 1 , wherein the control signal is designed to cause the resource consumption device to alter consumption of the resource.

5. The wireless node network of claim 1 , wherein the control signal is designed to adjust a display of the resource consumption control device.

6. The wireless node network of claim 5 , wherein the control signal is designed to generate an alert signal on the display.

7. The wireless node network of claim 1 , wherein the sensor device is a utility meter device.

8. The wireless node network of claim 1 , wherein the wireless module has a first housing and the actuator module has a second housing.

9. The wireless node network of claim 1 , wherein the wired communication interface includes a data communication signal connection and a clock signal connection.

10. The wireless node network of claim 1 , wherein the monitored location is a building.

11. A method, comprising:
transmitting, by a first of a plurality of wireless nodes installed at a monitored location via wireless communication, sensor data to a gateway device at the monitored location for delivery to a host system remote from the monitored location, the first of the plurality of wireless nodes configured to connect to a sensor device via a first wired interface connection, wherein the sensor data is based on measurements using the sensor device;
receiving, by a wireless module of a second of the plurality of wireless nodes installed at the monitored location via wireless communication, a control message from the gateway device, wherein the control message is based on an analysis by the host system of the transmitted sensor data to assess a demand at the monitored location of a resource;
transmitting, by a first controller of the wireless module, control information based on the control message to a second controller in a control module of the second of the plurality of wireless nodes via a wired communication interface that connects the wireless module to the control module, the control module having an actuator configured to connect to a resource consumption control device via a second wired interface connection; and
transmitting, by the actuator of the second of the plurality of the wireless nodes, a control signal to the resource consumption control device via the second wired interface connection, the control signal based on the received control information, the control signal configured to adjust a consumption of the resource using the resource consumption control device at the monitored location.

12. The method of claim 11 , wherein the wireless communication is based on the IEEE 802.15.4 protocol.

13. The method of claim 11 , wherein the control signal is designed to cause the resource consumption device to alter consumption of the resource.

14. The method of claim 11 , wherein the control signal is designed to adjust a display of the resource consumption control device.

15. The method of claim 14 , wherein the control signal is designed to generate an alert signal on the display.

16. The method of claim 11 , wherein the sensor device is a utility meter device.

17. The method of claim 11 , wherein the wireless module has a first housing and the control module has a second housing.

18. The method of claim 11 , wherein the wired communication interface includes a data communication signal connection and a clock signal connection.

19. The method of claim 11 , wherein the monitored location is a building.
