Abstract

A method of reducing power consumption of a receiver includes identifying a plurality of sensors for transmitting a signal, generating data for controlling a transmission operation of the plurality of sensors, and transmitting the data to the plurality of sensors.

Claims

1. A method of reducing power consumption of a receiver, the method comprising:

identifying sensors configured to transmit a signal;

generating data to control a transmission operation of the sensors; and

transmitting the data to the sensors,

wherein the generating data comprises combining a transmission time of a first sensor and a transmission time of a second sensor into a single period of an active mode section, each active mode section being separated from another active mode section by a sleep mode section during which receiving of the signal is disabled, and

wherein the data comprises time information indicating a period of time required to elapse before a sensor is permitted to transmit a signal in response to the sensor receiving the data.

2. The method of claim 1, wherein the generating of the data to control the transmission operation of the sensors identified comprises generating data to control the transmission operation of the sensors based on either one or both of a number of the sensors and identification information of the sensors.

3. The method of claim 1, wherein the generating of the data to control the transmission operation of the sensors identified comprises generating data to adjust a transmission time of the sensors.

4. The method of claim 1, wherein the generating of the data to control the transmission operation of the sensors identified comprises generating data to adjust the transmission operation for a signal to be transmitted by the sensors at predetermined intervals.

5. The method of claim 1, wherein the generating of the data to control the transmission operation of the sensors identified comprises generating data to adjust a communication frequency of the sensors.

6. The method of claim 1, wherein the generating of the data to control the transmission operation of the sensors identified comprises generating data to assign different communication frequencies or different communication frequency bands to the sensors.

7. The method of claim 1, further comprising setting an active mode period in which receiving of a signal is enabled and a sleep mode period in which receiving of a signal is disabled based on a transmission time of the sensors.

8. The method of claim 7, wherein the setting of the active mode period in which receiving of the signal is enabled and the setting of the sleep mode period in which receiving of the signal is disabled based on the transmission time of the sensors comprises setting the active mode period based on a transmission period at which the sensors transmit a signal and the transmission time of the sensors.

9. A non-transitory computer-readable storage medium storing a program for controlling a computer to perform the method of claim 1.

19. The method of claim 1, wherein the power consumption efficiency of the transmission is T1_on/(2*T1_on+2*T1_s), wherein T1_on is a duration of an active mode section required for the signal to be received and T1_s is a duration of a sleep mode section during which receiving of the signal is disabled and spanning successive active mode sections.

10. An apparatus for reducing power consumption, the apparatus comprising:

a sensor identifying unit configured to identify a sensors configured to transmit a signal;

a data generating unit configured to generate data to control a transmission operation of the sensors; and

a data transmitting unit configured to transmit the data to the sensors,

wherein the data generating unit is further configured to combine a transmission time of a first sensor and a transmission time of a second sensor into a single period of an active mode section, each active mode section being separated from another active mode section by a sleep mode section during which receiving of the signal is disabled, and

wherein the data comprises time information indicating a period of time required to elapse before a sensor is permitted to transmit a signal in response to the sensor receiving the data.

11. The apparatus of claim 10, wherein the data generating unit is further configured to generate data to control the transmission operation of the sensors based on any one or any combination of a number of the sensors and identification information of the sensors.

12. The apparatus of claim 10, wherein the data generating unit is further configured to generate data to adjust a transmission time of the sensors.

13. The apparatus of claim 10, wherein the data generating unit is further configured to generate data to adjust the transmission operation of the sensors for a signal to be transmitted by the sensors at predetermined intervals.

14. The apparatus of claim 10, wherein the data generating unit is further configured to generate data to adjust a communication frequency of the sensors.

15. The apparatus of claim 10, wherein the data generating unit is further configured to generate data to assign different communication frequencies or different communication frequency bands to the sensors.

16. The apparatus of claim 10, further comprising an operation mode setting unit for setting an active mode period in which receiving of a signal is enabled and a sleep mode period in which receiving of a signal is disabled based on a transmission time of the sensors.

17. The apparatus of claim 16, wherein the operation mode setting unit is further configured to set the active mode period based on a transmission period at which the sensors transmit a signal and the transmission time of the sensors.

18. A method of reducing power consumption of a receiver, the method comprising:

generating data to control sensors configured to transmit a signal to the receiver so that all of the sensors transmit respective signals to the receiver within a single active period during which the receiver is enabled to receive signals without creating interference between the signals, each active period being separated from another active period by a sleep period during which receiving of the signal is disabled; and

transmitting the data to the sensors, wherein the data comprises time information indicating a period of time required to elapse before a sensor is permitted to transmit a signal in response to the sensor receiving the data.
