Abstract

A freeze prediction system for components such as one or more water pipes situated in a building. The building may have a heating system, a mechanism with a temperature setting connected to the heating system, and an indoor temperature indicator connected to the thermostat. A call may be made for heat if thermostat setting is greater than an indoor temperature. A check may be made as to whether a call for heat may be answered. Outdoor conditions may be read and accounted for in the system. An expected time may be calculated of a freeze danger. One may determine whether the freeze danger is significant according to the expected time of freeze danger compared to a predetermined time. If the freeze danger is not significant, a regular equipment failed alert may be sent out. If the freeze danger is significant, a pipe freeze warning alert may be sent out.

First claim

What is claimed is:

1. A pipe freeze prediction system comprising:
one or more pipes situated in a building;
a heating system for the building;
a mechanism having a temperature setting for the heating system;
an indoor temperature sensor for sensing climate conditions inside the building;
one or more sensors for sensing climate conditions outside the building; and
a processor operationally coupled to the heating system, the mechanism, the indoor temperature sensor, and the one or more sensors, the processor configured to:
make a call to the heating system for heat if the temperature setting of the mechanism is more than a temperature sensed by the indoor temperature sensor;
monitor a sensed temperature in the building using the indoor temperature sensor in response to the call to the heating system for heat;
determine if the call for heat is answered based at least in part on the monitoring of the sensed temperature;
receive indoor information related to conditions inside the building using the indoor temperature sensor and outdoor information related to conditions outside the building using the one or more sensors in response to determining the call for heat is unanswered;
process the indoor information and the outdoor information to perform a trajectory analysis;
determine an expected freezing time based at least in part on the trajectory analysis; and
send out an alert based on the expected freezing time.

2. The system of claim 1 , wherein the trajectory analysis is used to calculate a temperature trajectory and the processor determines to send out a regular alert when the temperature trajectory is above a temperature threshold during a predetermined amount of time and determines to send out a danger alert when the temperature trajectory falls below the temperature threshold during the predetermined amount of time.

3. The system of claim 1 , wherein if the expected freezing time does exceed a predetermined time, then a regular equipment failed alert is sent out via the processor.

4. The system of claim 1 , wherein if the expected freezing time does not exceed a predetermined time, then a pipe freeze warning alert is sent out via the processor.

5. A method for determining predicting a water pipe freeze prediction, comprising:
watching for a heat failure in a building; and
wherein:
if there is no heat failure, then continue watching for a heat failure in the building;
if there is a heat failure, then determine whether temperature conditions outside of the building are freezing; or
if there is a heat failure, then an expected time of a freeze danger is calculated, and the expected time of a freeze danger is compared to a predetermined time to freeze to indicate whether a regular equipment failed alert or a pipe freeze warning alert is to be announced;
the watching for a heat failure, a calculation of the expected time of a freeze danger, an indication of a regular equipment failed alert, or a pipe freeze warning alert is performed by a processor;
the processor is situated in a cloud spatially apart from the building;
the cloud comprises:
a first portal for receiving information from a thermostat in the building;
a second portal for providing alerts to a person having an interest in or a responsibility for the building; and
a third portal for providing alerts to one or more contractors or repair people and for receiving one or more offers for repair or maintenance of the one or more contractors or repair people for repair or maintenance of the one or more pipes and heating systems, or for retrieving one or more offers for repair or maintenance from a database; and
wherein the one or more offers are provided via the second portal to the person having the interest or the responsibility for the building.

6. The method of claim 5 , further comprising determining whether the pipe freeze danger is significant according to the calculated expected time of the freeze danger.

7. The method of claim 6 , wherein if the freeze danger is not significant, then a regular equipment failed alert is sent out.

8. The method of claim 6 , wherein if the freeze danger is significant, then a pipe freeze warning alert is sent out.

9. The method of claim 6 , wherein the freeze danger is significant if the expected time of freeze danger is less than a predetermined time.

10. The method of claim 5 , wherein
a first portal is further configured to transmit information from the building and about an environment where the building is situated; and
a second portal is further configured to transmit indications of a pipe freeze warning alert and a regular equipment failed alert.

11. A water pipe freeze condition indicator comprising:
a thermostat in a building where a water pipe freeze condition can be detected;
a heating system connected to the thermostat; and
a processor situated in a cloud spatially at a distance from the building and connected to the thermostat; and
wherein the cloud comprises:
a first portal of receiving information from the thermostat;
a second portal for providing alerts to a person having an interest in or a responsibility for the building; and
a third portal for providing alerts to one or more contractors or repair people and for receiving one or more offers for repair or maintenance of the one or more pipes, or the heating system; and
wherein the one or more offers are provided via the second portal to the person having the interest in or the responsibility for the building; and

wherein:
the thermostat provides an indoor temperature, a temperature setting, and heat demand information to the processor;
the processor indicates whether there is a heat demand failure; and
if there is a heat demand failure, then the processor calculates an expected time of freeze danger to a water pipe.

12. The indicator of claim 11 , wherein the expected time of freeze danger to a water pipe is compared to a predetermined time to indicate whether a pipe freeze warning alert is to be provided.

13. The indicator of claim 12 , wherein if the expected time of freeze danger is less than the predetermined time, then a pipe freeze warning alert is provided.

14. The indicator of claim 12 , wherein if the expected time of freeze danger is equal to or greater than the predetermined time, then a regular equipment failed alert is provided.

15. The indicator of claim 11 , wherein:
the first portal further receives information from the building and about an environment where the building is situated; and
the second portal further provides indications of a pipe freeze warning alert and a regular equipment failed alert.
