The type of the signal 131 sent from the first external device 103 to the electronic device 101 is not limited. The type of the function performed by the electronic device 101 upon receiving the signal 131 is not limited. For example, the electronic device 101 receiving the signal 131 related to the on / off function may switch at least one component of the electronic device 101 to an active state or an inactive state.

The active state may be a state in which the state is an on state but not a working state. The active state may be a state in which the working state is in an on state. The electronic device 101 (for example, at least one component included in the electronic device 101) switched from the inactive state to the active state may perform a specific function of the electronic device 101. The inactive state may include an off state or a standby state.

The power control circuit 110 may control the switch 205 to provide power to the first power circuit 203 of the electronic device 101.

[0031] like Figure 2 As shown, the electronic device 101 may include a power control circuit 110. According to an embodiment, the electronic device 101 may not include the power control circuit 110. The power control circuit 110 may be implemented as a device separate from the electronic device 101. For example, a device including the power control circuit 110 (e.g., a power control device) may control the electronic device 101 (e.g., a device including the functional circuit 201 and the first power circuit 203). For example, a device including the power control circuit 110 (e.g., a power control device) may control the electronic device 101 (e.g., a device including the functional circuit 201 and the first power circuit 203) based on a signal from the first external device 103 or the second external device 105 (e.g., a relay device). Hereinafter, the description of the electronic device 101 including the power control circuit 110 may be similarly applicable to the power control circuit 110 implemented as a device separate from the electronic device 101.

[0032] For ease of description, the following definitions are made. The group including the functional circuit 201, the first power circuit 203 and the switch 205 may be referred to as the main group 210. The group including the controller 207, the communication module 211 and the second power circuit 209 may be referred to as the sub-group 220. The group including the signal detector may be referred to as the standby power saving group 230. The group including the power conversion circuit 217, the battery 219 and the collector 221 may be referred to as the collection group 240.

[0033] The electronic device 101 can perform a specific function using the main group 210. The specific function is a function unique to the electronic device 101, and the type of the specific function is not limited. For example, the specific function may be a screen display function, a cooling function, a washing function, a communication function, a control function, or an output function.

[0034] The electronic device 101 can use the sub-group 220 to control the power provided to the main group 210.

The electronic device 101 can provide a control signal from the sub-group 220 to the main group 210. The main group 210 can perform a specific function based on the signal provided from the sub-group 220.

[0035] The electronic device 101 can control the state of the subgroup 220 by using the standby power saving group 230. When a trigger signal is identified based on a signal provided from the outside, the electronic device 101 can control the state of the subgroup 220 using the standby power saving group 230. The trigger signal may be a signal indicating the activation of the subgroup 220 (e.g., the second power supply circuit 209). When the trigger signal is identified based on a signal provided from the outside using the standby power saving group 230, the electronic device 101 may provide a wake-up signal from the standby power saving group 230 to the subgroup 220. The wake-up signal may be a signal for switching the state of the subgroup 220 from an inactive state (e.g., a closed state) to an active state. When a signal (e.g., a wake-up signal) is received from the standby power saving group 230 in an inactive state (e.g., a closed state), the subgroup 220 may switch to an active state. The subgroup 220 may perform a specific function in an active state. The amount of power consumed by the standby power saving group 230 may be less than the amount of power consumed by the subgroup 220 in an inactive state (e.g., a closed state). The amount of power consumed may be the amount of power consumed during the same time period.

[0036] The standby power saving group 230 may receive power from the power supply 299. When the electronic device 101 does not include the acquisition group 240, the standby power saving group 230 may perform a specific function based on the power provided from the power supply 299.

When the switch 205 is controlled to be off by the controller 207, power may not be supplied from the power supply 299 to the first power supply circuit 203.

[0046] The second power supply circuit 209 may switch from an inactive state (e.g., an off state) to an active state based on a signal (e.g., a wake-up signal) provided from the signal detector 215. The second power supply circuit 209 may not provide power to the controller 207 in the inactive state. The second power supply circuit 209 may not provide power to the communication module 211 in the inactive state. The second power supply circuit 209 may provide power to the controller 207 in the active state.

The second power supply circuit 209 may provide power to the controller 207 based on a signal (e.g., a wake-up signal) provided from the signal detector 215. The second power supply circuit 209 may provide power to the communication module 211 based on a signal (e.g., a wake-up signal) provided from the signal detector 215.

[0047] The signal detector 215 may output a signal (e.g., a wake-up signal) to the second power supply circuit 209. When the second power supply circuit 209 is in an inactive state (e.g., an off state), the signal detector 215 may provide a signal (e.g., a wake-up signal) to the second power supply circuit 209. Upon recognizing a trigger signal based on a signal provided from the outside (e.g., the first external device 103 or the second external device 105), the signal detector 215 may provide a signal (e.g., a wake-up signal) to the second power supply circuit 209.

[0048] The signal detector 215 may be maintained in an active state by a power source (eg, power provided from the power source 299 , power provided from the acquisition group 240 , or power provided by a separate power source (eg, a battery) mounted on the electronic device 101 ).

The first signal may be a signal for activating the subgroup 220 of the electronic device 101 (e.g., the power control circuit 110). The first signal may be an IR signal, a Wi-Fi signal, or a BLE signal, depending on a communication scheme of a communication module of the external device (e.g., the first external device 103 or the second external device 105) that transmits the first signal. When the electronic device 101 (e.g., the power control circuit 110) includes a common receiver (e.g., Figure 5 510 or Figure 7 710), the electronic device 101 (eg, the power control circuit 110) may receive a signal from a common receiver (eg, Figure 5 510 or Figure 7 710) uses the signal detector 215 to detect a first signal provided from an external source (eg, the first external device 103 or the second external device 105).

[0074] The first signal provided from the outside may be a signal provided directly from the first external device 103 (e.g., a communication module of the first external device 103) to the electronic device 101 (e.g., a power control circuit 110). The first signal provided from the outside may be a signal provided from the second external device 105 to the electronic device 101 (e.g., a power control circuit 110). The first signal provided from the outside may be a signal provided from the second external device 105 (e.g., a relay device) to the electronic device 101 (e.g., a power control circuit 110) based on a signal provided from the first external device 103 to the second external device 105 (e.g., a relay device). The signal detector 215 may demodulate the received signal. The signal detector 215 may identify the trigger signal by demodulating the received signal.

The signal detector 215 may provide the wake-up signal to the second power supply circuit 209 based on identifying a first signal provided from the outside (e.g., the first external device 103 or the second external device 105). The signal detector 215 may provide the wake-up signal to the second power supply circuit 209 based on identifying a trigger signal by demodulating the first signal provided from the outside. The signal detector 215 may identify an external device (e.g., the first external device 103) associated with the first signal based on the trigger signal identified by demodulating the first signal (e.g., information about the ID of the external device included in the trigger signal). The signal detector 215 may provide the wake-up signal to the second power supply circuit 209 based on the external device (e.g., the first external device 103) associated with the first signal being a designated device. Reference will be made to the following. Fig. 9 A first signal provided from the outside and reception and demodulation of the first signal by the signal detector 215 are described.

[0076] In operation 807, the second power circuit 209 may enter the active state from the inactive state (eg, the off state). Upon receiving a signal (eg, a wake-up signal) from the signal detector 215, the second power circuit 209 may enter the active state from the inactive state (eg, the off state).

The second signal may be an IR signal, a Wi-Fi signal, or a BLE signal, depending on a communication scheme of a communication module of the external device (e.g., the first external device 103 or the second external device 105) that transmits the second signal. When the electronic device 101 (e.g., the power control circuit 110) includes a common receiver (e.g., Figure 5 510 or Figure 7 710), the electronic device 101 (eg, the power control circuit 110) may receive a signal from a common receiver (eg, Figure 5 510 or Figure 7 710) uses the communication module 211 to identify a second signal provided from the outside (eg, the first external device 103 or the second external device 105). When the electronic device 101 (eg, the power control circuit 110) includes a first receiver (eg, Figure 4 410 or Figure 6 610) and a second receiver (eg, Figure 4 420 or Figure 6 620), the electronic device 101 (eg, the power control circuit 110) may receive a signal from the first receiver (eg, Figure 4 410 or Figure 6 610) uses the communication module 211 to identify a second signal provided from the outside (e.g., the first external device 103 or the second external device 105). For example, both the first signal of operation 803 and the second signal of operation 813 may be signals sent from the communication module of the first external device 103 or the communication module of the second external device 105. For example, the first signal of operation 803 may be a signal sent from the communication module of the first external device 103, and the second signal of operation 813 may be a signal sent from the communication module of the second external device 105.

[0080] In operation 815, upon receiving a second signal (e.g., a signal for controlling the main group 210) through the communication module 211, the controller 207 may control the switch 205 to transmit power from the power source 299 to the first power circuit 203 through the switch 205. When the switch 205 is controlled to be turned on, power may be transmitted from the power source 299 to the first power circuit 203 through the switch 205.

[0081] In operation 817, the first power circuit 203 may transmit power to the functional circuit 201 based on the power transmitted from the power source 299 through the switch 205. The functional circuit 201 may perform a specific function based on the power transmitted from the first power circuit 203.
