Abstract

A system and method for adjusting power consumption of a power consumer (e.g., an intercom device) may include a power supply, the power consumer connected to the power supply through a transmitting device, and at least one processor. The at least one processor may be configured to obtain a first voltage associated with the power supply and a second voltage associated with the power consumer, and adjust an operation status of the power consumer at least based on the first voltage and the second voltage. The first voltage may be an output voltage of the power supply, and the second voltage may be an input voltage of the power consumer.

First claim

What is claimed is:

1. A system for communication, comprising:
a power supply;
a power consumer connected to the power supply through a transmitting device; and
at least one processor configured to:
obtain an output voltage of the power supply and an input voltage of the power consumer; and
adjust an operation status of the power consumer based at least in part on a voltage difference between the output voltage of the power supply and the input voltage of the power consumer, the voltage difference being a voltage drop caused by the transmitting device.

2. The system of claim 1 , wherein to adjust the operation status of the power consumer, the at least one processor is configured to:
obtain a mapping table that includes at least one reference index for the power consumer;
identify a target index from the at least one reference index based at least in part on the voltage difference; and
adjust the operation status of the power consumer based on the identified target index.

3. The system of claim 2 , wherein the mapping table associates the at least one reference index for the power consumer with at least one reference voltage difference, and wherein to identify the target index, the at least one processor is configured to:
identify, from the at least one reference voltage difference, a target voltage difference corresponding to the voltage difference; and
identify a reference index corresponding to the target voltage difference to be the target index.

4. The system of claim 3 , wherein the at least one processor is further configured to:
upon determining that the voltage difference is no less than a threshold value, send an alarm signal for adjusting a resistance of the transmitting device.

5. The system of claim 2 , wherein the at least one processor is further configured to: obtain an input current of the power consumer.

6. The system of claim 5 , wherein the mapping table associates the at least one reference index for the power consumer with at least one reference resistance of the transmitting device, and wherein to identify the target index, the at least one processor is configured to:
identify the target index from the at least one reference index based on the input current of the power consumer and the voltage difference.

7. The system of claim 6 , wherein to identify the target index, the at least one processor is configured to:
determine a resistance of the transmitting device based on the input current of the power consumer and the voltage difference;
identify, from the at least one reference resistance, a target resistance corresponding to the determined resistance of the transmitting device; and
identify a reference index corresponding to the target resistance to be the target index.

8. The system of claim 2 , wherein to adjust the operation status of the power consumer, the at least one processor is configured to:
adjust an operation index of the power consumer to be the target index.

9. The system of claim 8 , wherein the operation index of the power consumer is at least associated with a volume of the power consumer or a backlight brightness of the power consumer.

10. The system of claim 1 , wherein the power consumer includes an intercom device.

11. A method for communication, comprising:
obtaining, by at least one processor, an output voltage of a power supply and an input voltage of a power consumer, the power consumer being connected to the power supply through a transmitting device; and
adjusting, by the at least one processor, an operation status of the power consumer based at least in part on a voltage difference between the output voltage of the power supply and the input voltage of the power consumer, the voltage difference being a voltage drop caused by the transmitting device.

12. The method of claim 11 , wherein the adjusting of the operation status of the power consumer includes:
obtaining a mapping table that includes at least one reference index for the power consumer;
identifying a target index from the at least one reference index based at least in part on the voltage difference; and
adjusting the operation status of the power consumer based on the identified target index.

13. The method of claim 12 , wherein the mapping table associates the at least one reference index for the power consumer with at least one reference voltage difference, and the identifying of the target index includes:
identifying, from the at least one reference voltage difference, a target voltage difference corresponding to the voltage difference; and
identify a reference index corresponding to the target voltage difference to be the target index.

14. The method of claim 13 , further including:
upon determining that the voltage difference is no less than a threshold value, sending an alarm signal for adjusting a resistance of the transmitting device.

15. The method of claim 12 , further including: obtaining an input current of the power consumer, and wherein the mapping table associates the at least one reference index for the power consumer with at least one reference resistance of the transmitting device, and the identifying of the target index includes:
identifying the target index from the at least one reference index based on the input current of the power consumer and the voltage difference.

16. The method of claim 15 , wherein the identifying of the target index includes:
determining a resistance of the transmitting device based on the input current of the power consumer and the voltage difference;
identifying, from the at least one reference resistance, a target resistance corresponding to the determined resistance of the transmitting device; and
identifying a reference index corresponding to the target resistance to be the target index.

17. The method of claim 16 , further including:
upon determining that the resistance of the transmitting device is no less than a threshold value, sending an alarm signal for adjusting the resistance of the transmitting device.

18. The method of claim 12 , wherein the adjusting of the operation status of the power consumer includes:
adjusting an operation index of the power consumer to be the target index.

19. The method of claim 18 , wherein the operation index of the power consumer is at least associated with a volume of the power consumer or a backlight brightness of the power consumer.

20. A non-transitory computer readable medium, storing instructions, the instructions when executed by a processor, causing the processor to execute operations comprising:
obtaining an output voltage of a power supply and an input voltage of a power consumer, the power consumer being connected to the power supply through a transmitting device; and
adjusting an operation status of the power consumer based at least in part on the output voltage of the power supply and the input voltage of the power consumer, the voltage difference being a voltage drop caused by the transmitting device.
