Abstract

Disclosed is a method, apparatus and storage medium for controlling drainage of equipment. The method includes: determining that the equipment is in a drain state; detecting whether a floor drain connected to a drain pipe of the equipment is at risk of drainage overflow or a drainage overflow occurs; and when it is detected that the floor drain is at risk of drainage overflow or the drainage overflow occurs, reducing an amount of water discharging from the drain pipe per unit time.

First claim

What is claimed is:

1. A method for controlling drainage of equipment, the method comprising:
determining that the equipment is in a drain state, wherein the equipment comprises a drain pipe;
detecting whether a floor drain connected to the drain pipe of the equipment is at risk of drainage overflow or a drainage overflow occurs; and
reducing an amount of water discharging from the drain pipe per unit time in response to detecting that the floor drain is at risk of drainage overflow or the drainage overflow occurs;
wherein detecting whether the floor drain connected to the drain pipe of the equipment is at risk of drainage overflow or the drainage overflow occurs comprises:
detecting whether the floor drain is at risk of drainage overflow or the drainage overflow occurs according to an image of the drain pipe;
wherein the image of the drain pipe comprises at least two images of the drain pipe collected at different times, and determining whether the floor drain connected to the drain pipe is at risk of drainage overflow or the drainage overflow occurs according to the image of the drain pipe comprises:
determining a change amount of a position of the drain pipe in the at least two images, or determining a difference in image content between the at least two images;
determining that there is a risk of drainage overflow for the floor drain if it is determined in response to determining that the change amount of the position of the drain pipe in the at least two images exceeds a first threshold, or in response to determining that the difference in image content between the at least two images is greater than a second threshold; and
determining that the drainage overflow in response to determining that the difference in image content between the at least two images is greater than a third threshold.

2. The method according to claim 1 , wherein detecting whether the floor drain connected to the drain pipe of the equipment is at risk of drainage overflow or the drainage overflow occurs further comprises:
detecting whether the floor drain is at risk of drainage overflow or the drainage overflow occurs according to at least one of following data: a sound around the drain pipe, a water level in the floor drain, and a drain rate of the floor drain.

3. The method according to claim 2 , wherein determining whether the floor drain connected to the drain pipe is at risk of drainage overflow according to the sound around the drain pipe comprises:
determining that the floor drain is at risk of drainage overflow in response to determining that a difference between a first sound feature of the sound and a preset second sound feature is not greater than a fourth threshold.

4. The method according to claim 2 , wherein determining whether the floor drain connected to the drain pipe is at risk of drainage overflow or the drainage overflow occurs according to the water level in the floor drain and the drain rate of the floor drain comprises:
determining that the floor drain is at risk of drainage overflow in response to that the water level in the floor drain exceeds a preset position in the floor drain, the drain rate of the floor drain exceeds a first preset rate, or the drain rate of the floor drain is lower than a second preset rate; and
determining that the drainage overflow occurs in response to that the drain rate of the floor drain is lower than a third preset rate.

5. The method according to claim 1 , wherein the method further comprises:
after reducing the amount of water discharging from the drain pipe per unit time, increasing the amount of water discharging from the drain pipe per unit time in response to determining that the drainage overflow does not occur and the floor drain is not at risk of drainage overflow.

6. An apparatus for controlling drainage of equipment, the apparatus comprising:
a processor; and
a memory for storing instructions executable by the processor;
wherein the processor is configured to:
determine that the equipment is in a drain state, wherein the equipment is provided with a drain pipe;
detect whether a floor drain connected to the drain pipe of the equipment is at risk of drainage overflow or a drainage overflow occurs; and
reduce an amount of water discharging from the drain pipe per unit in response to determining that the floor drain is at risk of drainage overflow or the drainage overflow occurs;
wherein to detect whether the floor drain connected to the drain pipe of the equipment is at risk of drainage overflow or the drainage overflow occurs, the processor is further configured to:
detect whether the floor drain is at risk of drainage overflow or the drainage overflow occurs according to an image of the drain pipe;
wherein the image of the drain pipe comprises at least two images of the drain pipe collected at different times, and to determine whether the floor drain connected to the drain pipe is at risk of drainage overflow or the drainage overflow occurs according to the image of the drain pipe, the processor is further configured to:
determine a change amount of a position of the drain pipe in the at least two images, or determining a difference in image content between the at least two images;
determine that there is a risk of drainage overflow for the floor drain or in response to determining that the change amount of the position of the drain pipe in the at least two images exceeds a first threshold, or in response to determining that the difference in image content between the at least two images is greater than a second threshold; and
determine that the drainage overflow occurs or in response to determining that the difference in image content between the at least two images is greater than a third threshold.

7. The apparatus according to claim 6 , wherein the processor is further configured to:
detect whether the floor drain is at risk of drainage overflow or the drainage overflow occurs according to at least one of following data: a sound around the drain pipe, a water level in the floor drain, and a drain rate of the floor drain.

8. The apparatus according to claim 7 , wherein the processor is further configured to:
determine that the floor drain is at risk of drainage overflow in response to determining that a difference between a first sound feature of the sound and a preset second sound feature is not greater than a fourth threshold.

9. The apparatus according to claim 7 , wherein the processor is further configured to:
determine that the floor drain is at risk of drainage overflow in response to that the water level in the floor drain exceeds a preset position in the floor drain, the drain rate of the floor drain exceeds a first preset rate, or the drain rate of the floor drain is lower than a second preset rate; and
determine that the drainage overflow occurs in response to that the drain rate of the floor drain is lower than a third preset rate.

10. The apparatus according to claim 7 , wherein the processor is further configured to:
after the amount of water discharging from the drain pipe per unit time is reduced, increase the amount of water discharging from the drain pipe per unit time in response to determining that the drainage overflow does not occur for the floor drain and there is no risk of drainage overflow.

11. The apparatus according to claim 6 , wherein the processor is further configured to:
after the amount of water discharging from the drain pipe per unit time is reduced, increase the amount of water discharging from the drain pipe per unit time in response to determining that the drainage overflow does not occur for the floor drain and there is no risk of drainage overflow.
