Abstract

A connected roof drain assembly including a roof drain, a sensor group in operable communication with the roof drain and configured to output signals representative of the fluid flow therethough, and a communication assembly configured to receive the signals output by the sensor group and wirelessly transmit data to a user portal based at least in part on the signals output by the sensor group.

Claims (35)

1. A connected roof drain assembly comprising:

a roof drain;

a sensor group in operable communication with the roof drain and configured to output signals representative of the fluid flow through the roof drain; and

a communication assembly configured to receive the signals output by the sensor group and wirelessly transmit data to a user portal based at least in part on the signals output by the sensor group,

wherein the roof drain includes a Primary outlet and an overflow outlet, and wherein the sensor group is in fluid communication with the overflow outlet.

2. The connected roof drain assembly of claim 1 , wherein the communication assembly is configured to transmit a low alert, when the fluid flow level within the roof drain exceeds a first threshold, and wherein the communication assembly is a high alert when the fluid flow level within the roof drain exceeds a second threshold greater than the first threshold.

3. The connected roof drain assembly of claim 1 , wherein the communication assembly is configured to receive the signals output by the sensor group and maintain a sensor status state for each sensor to produce a sensor status matrix.

4. The connected roof drain assembly of claim 3 , wherein the communications assembly is configured to transmit the sensor status matrix to the user portal at predetermined time intervals, independent of any changes to the sensor status matrix.

5. The connected roof drain assembly of claim 4 , wherein the communications assembly is configured to transmit the sensor status matrix to the user portal in response to a change in the sensor status matrix.

6. The connected roof drain assembly of claim 3 , wherein the communications assembly is configured to transmit the entire sensor status matrix to the user profile in response to a change in the sensor status matrix.

7. The connected roof drain assembly of claim 4 , wherein the communications assembly is configured to update the entire sensor status matrix before each transmission.

8. The connected roof drain assembly of claim 1 , wherein the user portal includes a current status interface including a plurality of entries, each identifying a drain entity and listing the current status of the corresponding drain entity.

9. The connected roof drain assembly of claim 8 , wherein the drain entity includes a specific sensor group or roof drain.

10. A connected roof drain assembly comprising:

a roof drain;

a sensor group in operable communication with the roof drain and configured to output signals based at least in part on the flow of fluid through the roof drain, wherein the sensor group includes one or more sensors; and

a user portal configured to receive and analyze the signals output by the sensor group, wherein the user portal is also configured to receive and analyze weather information from a weather source, and wherein the user portal is configured to produce a set of alert conditions for the at least one of the one or more sensors of the sensor group based at least in part on the signals from the sensor group and the weather information.

11. The connected roof drain assembly of claim 10 , wherein the set of alert conditions may include at least one of a threshold overall volume of rainfall, or a threshold rate of rainfall.

12. The connected roof drain assembly of claim 10 , wherein the user portal is in wireless communication with the sensor group via a communication assembly.

13. The connected roof drain assembly of claim 12 , wherein the communication assembly is configured to interpret the signals from the sensor group as one or more alerts.

14. The connected roof drain assembly of claim 10 , wherein the weather information is gathered from sensors positioned locally to the roof drain.

15. The connected roof drain assembly of claim 10 , wherein the user portal is configured to receive and analyze weather forecast data, and wherein the user portal is configured to predict the time an alert may occur based at least in part on the forecast data and the alert conditions.

16. The connected roof drain assembly of claim 10 , wherein the portal is configured to display the current status of one or more drain entities.

17. The connected roof drain assembly of claim 16 , wherein the roof drain assembly includes one of the roof drain and the one or more sensors of the sensor group.

18. A connected roof drain assembly for use with a cloud network, the connected roof drain assembly comprising:

a roof drain;

a sensor group in operable communication with the roof drain and configured to output signals representative of the fluid flow therethough; and

a communication assembly configured to receive the signals output by the sensor group and maintain a sensor status state for each sensor to produce a sensor status matrix, wherein the communication assembly is configured to wirelessly transmit the sensor status matrix to the cloud network.

19. The connected roof drain assembly of claim 18 , wherein the communication assembly is configured to receive signals from the cloud network.

20. A connected roof drain assembly comprising:

a roof drain;

a sensor group in operable communication with the roof drain and configured to output signals representative of the fluid flow therethrough; and

a connection interface configured to receive the signals output by the sensor group and maintain a sensor status state for each sensor to produce a sensor status matrix.

21. The connected roof drain assembly of claim 20 , wherein the connection interface is configured to transmit the sensor status matrix to a user portal at predetermined time intervals independent of any changes to the sensor matrix.

22. The connected roof drain assembly of claim 20 , wherein the connection interface is configured to transmit the sensor status matrix to a user portal in response to a change in the sensor status matrix.
