Abstract

Provided are a method and device for controlling electric heating of an air conditioner compressor. The method may include: first request information is transmitted to a corresponding database server at an interval of a second preset duration, as to acquire weather forecast data of an area where an air conditioner is located within an upcoming third preset duration; the weather forecast data returned by the database server is received and stored in a built-in database of the air conditioner; it is monitored to learn that a shutdown duration of the air conditioner compressor exceeds a first preset duration, as to acquire the weather forecast data stored in the built-in database of the air conditioner; and a control strategy is generated according to the weather forecast data, to control the air conditioner compressor to start and stop electric heating.

First claim

What is claimed is:

1. A method for controlling electric heating of an air conditioner compressor, comprising:
monitoring, by a controller of the air conditioner, to learn that a shutdown operation of the air conditioner compressor exceeds a first preset duration, acquiring weather forecast data; and
generating, by the controller of the air conditioner, according to the weather forecast data, a control strategy to control starting and stopping electric heating of the air conditioner compressor.

2. The method for controlling electric heating of an air conditioner compressor of claim 1 , wherein before monitoring, by the controller of the air conditioner, to learn that the shutdown operation of the air conditioner compressor exceeds the first preset duration, the method further comprises:
transmitting, by the controller of the air conditioner, first request information to a corresponding database server at an interval of a second preset duration so as to acquire the weather forecast data of an area where the air conditioner is located within an upcoming third preset duration; and
receiving, by the controller of the air conditioner, the weather forecast data returned by the database server and storing the weather forecast data in a built-in database of the air conditioner.

3. The method for controlling electric heating of an air conditioner compressor of claim 2 , wherein transmitting, by the controller of the air conditioner, the first request information to the corresponding database server at the interval of the second preset duration so as to acquire the weather forecast data of the area where the air conditioner is located within the upcoming third preset duration comprises:
determining location information of the air conditioner;
acquiring the third preset duration threshold that is preset; and
generating the first request information including the location information of the air conditioner and the third preset duration threshold, and transmitting the first request information to the database server to acquire the weather forecast data of the area where the air conditioner is located within the upcoming third preset duration.

4. The method for controlling electric heating of an air conditioner compressor of claim 2 , wherein generating, by the controller of the air conditioner, according to the weather forecast data, the control strategy to control starting and stopping electric heating of the air conditioner compressor comprises:
screening, from the weather forecast data stored in the built-in database of the air conditioner, weather forecast data within a fourth preset duration after a present time; and
analyzing to determine a change trend along time of a temperature in the weather forecast data within the fourth preset duration, controlling starting electric heating of the air conditioner compressor within a duration during which an ascending trend is shown, and controlling stopping electric heating of the air conditioner compressor within a duration during which a non-ascending trend is shown.

5. The method for controlling electric heating of an air conditioner compressor of claim 4 , wherein analyzing to determine the change trend along time of the temperature in the weather forecast data within the fourth preset duration comprises:
dividing the fourth preset duration into n preset unit time periods equally, and recording as F1 . . . Fk . . . Fn respectively, where n and k are natural numbers, k being whole integers from 2 to n;
calculating a mean temperature within each of n unit time periods F1 . . . Fk . . . Fn, and recording as t1 . . . tk . . . tn respectively; and
comparing the mean temperature within each current time period with the mean temperature within a time period immediately preceding the current time period so as to determine the change trend along time of the temperature in the weather forecast data within the fourth preset duration.

6. The method for controlling electric heating of an air conditioner compressor of claim 5 , wherein comparing the mean temperature within each current time period with the mean temperature within the time period immediately preceding the current time period so as to determine the change trend along time of the temperature in the weather forecast data within the fourth preset duration comprises:
determining that the change trend along time of the temperature within a Fk time period is an ascending trend when tk-t(k−1)>0; and
determining that the change trend along time of the temperature within a Fk time period is a non-ascending trend when tk-t(k−1)≤0.

7. The method for controlling electric heating of an air conditioner compressor of claim 6 , wherein is indicative of the weather forecast data within the fourth preset duration being completely processed, and monitoring is continued to learn whether the shutdown duration of the air conditioner compressor exceeds the first preset duration.

8. A device for controlling electric heating of an air conditioner compressor, comprising at least one processor and a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon, which when the at least one computer executable instruction is executed by the at least one processor, causes the at least one processor to carry out following actions:
monitoring by a controller of the air conditioner, to learn that a shutdown operation of the air conditioner compressor exceeds a first preset duration, acquiring weather forecast data; and
generating by the controller of the air conditioner, according to the weather forecast data, a control strategy to control starting and stopping electric heating of the air conditioner compressor.

9. The device for controlling electric heating of an air conditioner compressor of claim 8 , the actions further comprising:
before monitoring by the controller of the air conditioner, to learn that the shutdown operation of the air conditioner compressor exceeds the first preset duration, transmitting by the controller of the air conditioner, first request information to a corresponding database server at an interval of a second preset duration so as to acquire the weather forecast data of an area where the air conditioner is located within an upcoming third preset duration; and
receiving by the controller of the air conditioner the weather forecast data returned by the database server and storing the weather forecast data in a built-in database of the air conditioner.

10. The device for controlling electric heating of an air conditioner compressor of claim 9 , wherein transmitting by the controller of the air conditioner the second request information to the corresponding database server at the interval of the first preset duration so as to acquire the weather forecast data of the area where the air conditioner is located within the upcoming third preset duration comprises:
determining location information of the air conditioner;
acquiring the third preset duration threshold that is preset; and
generating the first request information including the location information of the air conditioner and the third preset duration threshold, and transmitting to the database server to acquire the weather forecast data of the area where the air conditioner is located within the upcoming third preset duration.

11. The device for controlling electric heating of an air conditioner compressor of claim 9 , wherein generating by the controller of the air conditioner, according to the weather forecast data, the control strategy to control starting and stopping electric heating of the air conditioner compressor comprises:
screening, from the weather forecast data st
