Description

Electronic device and control method thereof

[0001] The present disclosure relates to an electronic device and a method for controlling the same. More specifically, the present disclosure relates to an electronic device for supplying charging power to a robot and a method for controlling the same.

[0002] The robot can utilize power via a battery. The robot can move using the power stored in the battery. The robot can receive power from a charging station corresponding to the battery capacity. To charge the robot, the charging station can receive source power from an external power source. The charging station can convert the source power and supply it to the robot.

[0003] The charging station can convert source power based on a pre-configured conversion method. The charging station can supply the converted power to the robot. The charging station may not need to perform all functions at times when it is not providing charging capabilities for the robot.

[0004] Even when charging functions were not provided, there was a problem of wasted power due to the high standby power consumption of the charging station. Users experienced inconvenience when manually operating the power-saving mode to address this power waste. Furthermore, when the power-saving mode was activated based on factors such as standby time, there was a problem where even essential functions of the charging station were disabled.

[0005] For example, there was a problem where the charging station could not detect whether the robot was docked in power-saving mode, even though it is supposed to detect whether the robot is docked.

[0006] The foregoing information is provided solely as background information to aid in understanding the present disclosure. No determination has been made, nor is any claim made, as to which of the foregoing information may be applied as prior art relating to the present disclosure.

[0073] Referring to FIG. 1, this is a drawing for explaining a system (1000) including an electronic device (100) and a robot such as a mobile robot (200).

[0074] The system (1000) may include an electronic device (100) and a mobile robot (200).

[0075] The electronic device (100) may be a device that performs a charging function for charging a mobile robot (200).

When the mobile robot (200) comes into contact with the electronic device (100), the electronic device (100) can supply power to the mobile robot (200). The mobile robot (200) can perform a charging function using the power received from the electronic device (100).

[0078] FIG. 2 is a block diagram illustrating an electronic device (100) according to one embodiment of the present disclosure.

[0079] Referring to FIG. 2, the electronic device (100) may be a device that supplies charging power to the robot (200). The electronic device (100) may be a charging device for charging the battery of the robot (200). The robot (200) may be a mobile robot. The robot (200) may move near the electronic device (100) for charging. The electronic device (100) may be described as a charging station, a charging power supply, a power supply, etc.

[0080] The electronic device (100) may include a memory (110) for storing instructions, at least one processor (120) including processing circuitry, and a sensor unit (180).

[0081] The sensor unit (180) may include a power sensor (181) for sensing the internal power of the electronic device (100) and a docking sensor (182) for sensing whether the robot (200) is docked. Descriptions related to the sensor unit (180) are described in FIGS. 5 to 7.

[0082] At least one processor (120) may operate in a normal mode. The normal mode may represent a mode that performs the function of supplying charging power to the robot (200). The normal mode may be a mode that supplies charging power or a mode that operates in a state where charging power can be supplied.

[0083] At least one processor (120) can acquire a voltage value through a power sensor (181) while operating in a normal mode to perform a charging function for the robot (200). The electronic device (100) can sense a power value for a specific part of the electronic device (100) through the power sensor (181). The specific part may be a part where the voltage value (or current value) differs depending on whether the charging function of the electronic device (100) is currently being provided. The specific part may be described as a target part. The target part may be changed according to the user's settings.

[0084] At least one processor (120) can acquire sensing data including a voltage value through a power sensor (181). At least one processor (120) can compare the voltage value and the threshold voltage value. At least one processor (120) can determine whether to switch from normal mode to sleep mode based on the comparison result.

[0085] At least one processor (120) can identify whether the voltage value is below a threshold voltage value. If the voltage value is below the threshold voltage value, at least one processor (120) can determine that the current electronic device (100) does not need to provide a charging function.

[0086] If the voltage value is less than the threshold voltage value, at least one processor (120) can change the normal mode to a first sleep mode or a second sleep mode based on docking data from the docking sensor (182).

[0087] The electronic device (100) may operate in a normal mode or a power-saving mode. The normal mode may be a mode that supplies charging power to the robot (200). While operating in the normal mode, the electronic device (100) may supply power to the robot (200) or maintain a state in which it can supply power to the robot (200).

[0088] The power saving mode may be a mode for saving power of the electronic device (100). While operating in power saving mode, the electronic device (100) may operate without supplying power to the robot (200). The electronic device (100) may save power consumption by disabling the module associated with the operation of supplying power to the robot (200).

[0089] The electronic device (100) may operate in a normal mode when it is determined that a charging function is needed. When the robot (200) is docked to the electronic device (100) and the robot (200)'s battery is not fully charged, the electronic device (100) may determine that a charging function is needed.

[0090] The electronic device (100) may operate in a power-saving mode when it is determined that a charging function is not required. The power-saving mode may include a first sleep mode and a second sleep mode. The first sleep mode and the second sleep mode may be modes for reducing power consumption.

[0091] The first sleep mode may be a mode for supplying minimal power. The first sleep mode may be a mode for deactivating both the module for supplying power to the sensor unit (180) (the second conversion module (12)) and the module for performing a charging function (e.g., the third conversion module (13), the fourth conversion module (14)).

[0092] The first sleep mode may be a mode in which the charging function is not performed while power is not supplied to the sensor unit (180). It may be a mode in which the charging function is turned off to save power, and power is not supplied to the sensor unit (180).

[0093] The first sleep mode may be a power saving mode performed when the robot (200) is docked. The first sleep mode may be a mode that disables the sensor unit (180) for sensing whether the robot (200) is docked and turns off the charging function.

[0094] The second sleep mode may be a mode in which the charging function is not performed while power is supplied to the sensor unit (180). The second sleep mode may be a mode in which the charging function is turned off to save power, but power is supplied to the sensor unit (180).

[0095] The second sleep mode may be a mode that activates a module (second conversion module (12)) for supplying power to the sensor unit (180) in the first sleep mode. The second sleep mode may be a mode that supplies power to the sensor unit (180) but disables a module for performing a charging function.

[0096] The second sleep mode may be a power saving mode performed when the robot (200) is not docked. The second sleep mode may be a mode that activates a sensor unit (180) for sensing whether the robot (200) is docked and turns off the charging function.

[0097] If the robot (200) is docked to the electronic device (100) and the robot (200)'s battery is fully charged, the electronic device (100) may determine that a charging function is not required. If the robot (200) is docked to the electronic device (100) and the robot (200)'s battery is fully charged, the electronic device (100) may determine that a charging function is not required and that there is no need to sense whether the robot (200) is docked. The electronic device (100) may operate in a first sleep mode that disables both the module for the charging function and the module supplying power to the sensor unit (180).

[0098] If the robot (200) is not docked to the electronic device (100), the electronic device (100) may determine that a charging function is not required. If the robot (200) is not docked to the electronic device (100), the electronic device (100) may determine that power supply to the sensor unit (180) is required to activate the docking sensor (182) for identifying whether the robot (200) is docked to the electronic device (100). The electronic device (100) may operate in a second sleep mode that supplies power to the sensor unit (180) to sense whether the robot (200) is docked, but disables the charging function.

[0099] If the voltage value obtained through the power sensor (181) is greater than or equal to the threshold voltage value, the electronic device (100) may determine that a charging function is required. If the voltage value is greater than or equal to the threshold voltage value, the electronic device (100) may determine that it is in a state of supplying charging power to the robot (200) or that there is a need to supply charging power.

[0100] If the voltage value obtained through the power sensor (181) is less than the threshold voltage value, the electronic device (100) may determine that a charging function is not required. If the sensed voltage value is less than the threshold voltage value, the electronic device (100) may determine that a charging function is not performed.

[0101] If the voltage value sensed while operating in normal mode is less than the threshold voltage value, the electronic device (100) can change the normal mode to a power-saving mode.

[0102] The power saving mode may include a first sleep mode and a second sleep mode. The first sleep mode and the second sleep mode may be modes for reducing power consumption. The electronic device (100) may perform either the first sleep mode or the second sleep mode depending on whether the robot (200) is docked. If the robot (200) is docked to the electronic device (100), the electronic device (100) may perform the first sleep mode. If the robot (200) is not docked to the electronic device (100), the electronic device (100) may perform the second sleep mode.

[0103] The first sleep mode or the second sleep mode may be described as the first power saving mode or the second power saving mode.

[0104] At least one processor (120) can identify whether the robot (200) is docked based on docking data if the voltage value is less than the threshold voltage value.

[0105] When the robot (200) is identified as docked, at least one processor (120) can control the electronic device (100) to operate in a first sleep mode.

[0106] If it is identified that the robot (200) is not docked, at least one processor (120) can control the electronic device (100) to operate in a second sleep mode.

[0107] The reason for distinguishing whether power is supplied to the sensor unit (180) is that the possibility of docking the robot (200) affects the power supply method. When the robot (200) is docked, there may no longer be a need to detect whether the robot (200) is docked. When the robot (200) is already docked, there may not be a need to prepare for docking the robot (200). When the robot (200) is not docked, there is a need to prepare for a situation where the robot (200) is docked.

[0108] If the voltage value is less than the threshold voltage value, at least one processor (120) can decide to switch from normal mode to sleep mode. At least one processor (120) can determine the type of slim board based on docking data.

[0109] If the robot (200) is docked while the voltage value is below the threshold voltage value, at least one processor (120) can control the electronic device (100) to operate in a first sleep mode.

[0110] If the robot (200) is not docked while the voltage value is below the threshold voltage value, at least one processor (120) can control the electronic device (100) to operate in a second sleep mode.

[0226] Referring to FIG. 8, the electronic device (100) can apply power (S810). The electronic device (100) can receive power from an external source. The electronic device (100) can apply a source voltage.

[0227] When power is applied, the electronic device (100) can perform a normal mode (S820). The electronic device (100) can operate in a normal mode. The normal mode may be a mode in which the electronic device (100) operates in a state where it can perform a charging function. The electronic device (100) can activate at least one module necessary for preparing to charge the robot (200). The normal mode may be a mode that activates at least one module necessary for the charging function.

[0228] The electronic device (100) can identify whether the sensed voltage value is less than a threshold voltage value (S835). The electronic device (100) can sense the voltage value through a power sensor (181). A description of the power sensor (181) is provided in FIGS. 5 to 7.

[0229] The electronic device (100) can obtain a voltage value through a power sensor (181). The electronic device (100) can compare the voltage value with a previously stored threshold voltage value.

[0230] If the voltage value is lower than the threshold voltage value (S835-N), the electronic device (100) can determine a slim mode (S860). The electronic device (100) can operate as a slim board. The sleep mode may be a mode for saving power of the electronic device (100). The sleep mode may be a mode for deactivating at least one active module in the electronic device (100). Based on the same amount of time, the power consumed in the sleep mode may be less than the power consumed in the normal mode.

[0231] While operating in sleep mode, the electronic device (100) can identify a preset event (S850). The preset event may include an event for exiting sleep mode. The preset event may be an event for operating in normal mode. The preset event may be an event for starting normal mode.

[0232] For example, a preset event may include at least one of an event in which a first threshold time elapses from the time the sleep mode starts, an event in which a robot (200) movement command is received, an event in which the robot (200) is docked while in an undocking state, an event in which the dustbin cover is opened, and an event in which the water tank cover is opened.

The electronic device (100) can change the current mode from sleep mode to normal mode. The electronic device (100) can repeat the operations S820, S835, S850, and S860.

[0234] According to another embodiment, the electronic device (100) may obtain a current value rather than a voltage value. The electronic device (100) may compare the current value with a threshold current value. The electronic device (100) may determine to perform a sleep mode if the current value is less than the threshold current value. The method of using the current value may be applied in the same way as described in the drawings below.

[0313] In the embodiment of FIG. 15, the electronic device (100) may not activate both the third conversion module (13) and the fourth conversion module (14) at once. The electronic device (100) may activate the third conversion module (13) or the fourth conversion module (14) by checking the power status of the robot (200) and taking into account the battery charge level of the robot (200).

[0314] When the third conversion module (13) is activated and the remaining battery capacity of the robot (200) increases, the electronic device (100) can activate the fourth conversion module (14). An explanation related to this is described in FIG. 16.

[0315] FIG. 15 describes an example in which a robot (200) transmits the remaining battery capacity. If the robot (200) is in a completely discharged state, it may be difficult to transmit the remaining battery capacity. An explanation related to this is described in FIG. 16.
