Abstract

Devices, methods, and systems for building monitoring are described herein. One or more embodiments include a first transceiver coupled to a first phase of a power system of a building and configured to receive and send data over the first phase of the power system, a second transceiver coupled to a second phase of the power system and configured to receive and send data over the second phase of the power system, and a switch coupled to the first and second transceivers of the power system and configured to route data between the first and second transceivers of the power system.

Claims

1. A device for building monitoring, comprising:

a first transceiver coupled to a first phase of a power system of a building and configured to receive and send data over the first phase of the power system, wherein the data received over the first phase of the power system by the first transceiver includes data from a first sensor;

a second transceiver coupled to a second phase of the power system and configured to receive and send data over the second phase of the power system, wherein the data sent over the second phase of the power system by the second transceiver includes data sent to a control device;

a third transceiver coupled to a third phase of the power system and configured to receive and send data over the third phase of the power system, wherein the data received over the third phase of the power system by the third transceiver includes data from a second sensor; and

a switch coupled to the first, second, and third transceivers of the power system and configured to route data between the first, second, and third transceivers of the power system, wherein the data routed between the first, second, and third transceivers of the power system includes;

the data from the first sensor being routed from the first transceiver to the second transceiver; and

the data from the second sensor being routed from the third transceiver to the second transceiver; and

wherein the data sent to the control device over the second phase of the power system by the second transceiver includes the data from the first sensor and the data from the second sensor.

2. The device of claim 1, wherein the device includes a wireless interface coupled to the switch, wherein the wireless interface is configured to send data received by the first and second transceivers of the power system to a wireless or wired device.

3. The device of claim 1, wherein the device includes a memory coupled to the switch, wherein the memory is configured to store data received by the first and second transceivers of the power system.

4. The device of claim 1, wherein the power system is a power line communication network.

5. The device of claim 1, wherein the device is located at a power distribution point of the building.

6. A method for building monitoring, comprising:

receiving data from a sensor over a first phase of a power system of a building;

routing the data from the first phase of the power system to a second phase of the power system;

sending the data to a control device over the second phase of the power system;

receiving data from an additional sensor over a third phase of the power system;

routing the data received from the additional sensor from the third phase of the power system to the second phase of the power system; and

sending the data received from the additional sensor to the control device over the second phase of the power system.

7. The method of claim 6, wherein the method includes:

storing the data received from the sensor; and

sending the data received from the sensor to the control device subsequent to storing the data received from the sensor.

8. The method of claim 6, wherein the method includes:

storing the data received from the sensor; and

sending the data received from the sensor to a wireless or wired device subsequent to storing the data received from the sensor.

9. The method of claim 8, wherein sending the data received from the sensor to the wireless device includes:

sending the data received from the sensor to a wireless access point over the first or second phase of the power system; and

sending the data received from the sensor from the wireless access point to the wireless device.

10. A system for building monitoring, comprising:

a sensor coupled to a first phase of a power system of a building;

a control device coupled to a second phase of the power system;

a wireless access point coupled to a third phase of the power system; and

an aggregation unit coupled to the first, second, and third phases of the power system, wherein the aggregation unit includes;

a first transceiver coupled to the first phase of the power system and configured to receive data from the sensor over the first phase of the power system;

a second transceiver coupled to the second phase of the power system and configured to send data to the control device over the second phase of the power system;

a third transceiver coupled to the third phase of the power system, wherein the third transceiver is configured to send data to the wireless access point over the third phase of the power system; and

a switch coupled to the first, second, and third transceivers of the power system and configured to;

route data from the first transceiver of the power system to the second transceiver of the power system; and

route data from the first and second transceivers of the power system to the third transceiver of the power system.

11. The system of claim 10, wherein the wireless access point is configured to send data to a wireless device.

12. The system of claim 10, wherein the sensor is configured to send sensed data to the first transceiver of the power system in response to a request from the aggregation unit.

13. The system of claim 10, wherein the sensor is configured to automatically send sensed data to the first transceiver of the power system.

14. The system of claim 10, wherein the sensor is configured to:

store sensed data; and

send the sensed data to the first transceiver of the power system subsequent to storing the sensed data.

15. The system of claim 10, wherein the sensor includes a transceiver coupled to the first phase of the power system and configured to send data to the first transceiver over the first phase of the power system.

16. The system of claim 10, wherein the control device includes a transceiver coupled to the second phase of the power system and configured to receive data from the second transceiver over the second phase of the power system.

17. The system of claim 10, wherein the control device is coupled to an outlet of the power system in the building.
