A method of shutting off power connected to the 114 and the third sub-connectors 115 will be described in detail. In addition, in the smart connector 100 according to the embodiment of the present invention, the connector unit 110 may include a main connector 111, a first sub connector 113, a second sub connector 114, and a third sub connector 115. Although the power supply of the smart connector according to an embodiment of the present invention, the main connector 111, the first sub connector 113, the second sub connector 114 and the third sub connector 115, respectively. Since the same method is applied to selectively disconnect the connected power source, the main connector 111, the first sub connector 113, the second sub connector 114, and the third sub connector 115 are described below for convenience of description. A method for shutting off the power of the smart connector will be described with the center of the power supply connected to the connector unit 110 included.

First, the power measuring unit 131 of the smart connector 100 generates power amount data on power consumption of an electronic device connected to the connector unit 110 of the smart connector 100 at a predetermined time interval (S110). ). For example, when the preset time interval is 0.3 seconds, the power measurement unit 110 may generate the power amount data by measuring the amount of power consumed by the electronic device connected to the connector unit at 0.3 second intervals. It is not limited to the above example.

The power measuring unit 131 may measure the power consumption of the electronic device connected to the connector 110 from the moment the electronic device is connected to the connector 110. Alternatively, the power measurement unit 131 may measure the power consumption of the electronic device connected to the connector unit 110 from the moment the power is connected to the connector unit 110 by the gesture recognition unit 180.

Next, the power cutoff unit 132 of the smart connector 110 calculates a power amount deviation using the power amount data and compares it with a reference value previously stored in the memory unit 133 of the smart connector 100 (S120). .

In this case, the power cutoff unit 132 may select the most recent three of the power amount data generated from the power measuring unit 131 to calculate the power amount deviation. The power cutoff unit 132 may extract the three most recent power amount data and set the first power amount data, the second power amount data, and the third power amount data based on the fastness of the order in which the power amount data is generated. For example, the power cutoff unit 132 sets the most recent power amount data as the third power amount data, and sets the power amount data generated 0.3 seconds before the most recent power amount data as the second power amount data. The power amount data generated 0.6 seconds before the latest power amount data may be set as the first power amount data, but is not limited to the above example. That is, the power cutoff unit 132 sets the most recent power amount data as the third power amount data (S120a), and sets the power amount data generated after a predetermined time from the time when the third power amount data is generated. The power amount data and the first power amount data may be set (S120b and S120c).

Meanwhile, the power cutoff unit 132 converts the second power amount data into the first power amount data after maintaining the state in which the power is connected to the connector unit 120 to be described below (S150) (S200). The third power amount data may be converted into the second power amount data (S2210), and the latest power amount data may be set as the third power amount data (S220), but is not limited to the above example. That is, the power cut-off unit 132 always performs the most recent power amount data while comparing the power amount data with the reference value or standby power reference value by performing the power off method of the smart connector according to the embodiment of the present invention. The power amount data may be set, and the power amount data generated after a predetermined time from the time generated as the third power amount data may be set as the second power amount data and the first power amount data, but is not limited to the above example.

The power cutoff unit 132 may calculate the power amount deviation using the power amount data. That is, the power cutoff unit 132 may calculate the power amount deviation using the first power amount data, the second power amount data, and the third power amount data. In this case, the power cutoff unit 132 may calculate the power amount deviation by dividing the power amount deviation into a first power amount deviation and a second power amount deviation. For example, the power cutoff unit 132 may calculate the difference between the first power amount data and the second power amount data and set the difference as the first power amount deviation, and the difference between the second power amount data and the third power amount data. May be calculated and set as the second power amount deviation, but is not limited to the above example.

The power cutoff unit 132 compares the first power amount deviation and the second power amount deviation with the reference value (S120d). When the first power amount deviation is less than the reference value and the second power amount deviation is less than the reference value, the power cutoff unit 132 may determine that the power amount deviation is less than the reference value. On the other hand, when at least one of the first power amount deviation or the second power amount deviation is greater than or equal to the reference value, the power cutoff unit 132 may determine that the power amount deviation is greater than or equal to the reference value.

When the power cutoff unit 132 determines that the power amount deviation is less than the reference value, the power cutoff unit 132 determines whether the standby power reference value is set in the memory unit 133 (S130). In this case, the memory unit 133 may not initially set the standby power reference value. In addition, when the power source connected to the connector unit 110 is cut off, the controller 130 may delete the standby power reference value stored in the memory unit 133. That is, the memory unit 133 may not always set the standby power reference value initially.

When the standby power reference value is not set in the memory unit 133, the power cutoff unit 132 sets the standby power reference value using the power amount data (S140), and a power is connected to the connector unit 110. It is maintained (S150). The power cutoff unit 132 may calculate an average of the first power amount data, the second power amount data, and the third power amount data, set the standby power reference value, and store the average power reference value in the memory unit 133. The standby power reference value set by the power cutoff unit 132 may be a value for power consumption consumed by the electronic device when the electronic device connected to the connector unit 110 is not operated and is in a standby state. That is, the power cutoff unit 132 may set the standby power value consumed by the electronic device as the standby power reference value.

At this time, the power cutoff unit 132 compares the set standby power reference value and the first power amount data (S140a). If the standby power reference value is equal to or less than the first power amount data, the power cutoff unit 132 maintains a state in which power is connected to the connector unit 110 (S150). On the other hand, when the standby power reference value exceeds the first power amount data, the power cutoff unit 132 sets the standby power reference value as the first power amount data (S140b) and connects power to the connector unit 110. It is maintained (S150). That is, the method of shutting off the smart connector according to the embodiment of the present invention can prevent the standby power reference value from being set too high. Accordingly, the method for shutting off the smart connector according to the embodiment of the present invention may prevent the power connected to the connector unit 110 to which the standby electronic device is connected by setting the standby power reference value excessively high. have.

On the other hand, in the method of shutting off the smart connector, the standby power reference value is not set in the memory unit 133, and the power amount deviation before the power cutoff unit 132 sets the standby power reference value using the power amount data. To calculate and compare with the reference value (S120d), and check whether the standby power reference value is set in the memory unit 133 (S130) can be repeated several times. At this time, the power cut-off unit 132 converts the second power amount data to the first power amount data as described above (S200), and converts the third power amount data to the second power amount data as described above. (S210), the most recent power amount data may be set as the third power amount data (S220) and applied to the step.

Next, when the standby power reference value is set in the memory unit 133, the power cutoff unit 132 selectively selects power connected to the connector unit 110 using the power amount data, the standby power reference value, and the reference value. Block (S160).

In detail, in operation S160, the power cutoff unit 132 selectively cuts off the power connected to the connector unit 110. The power cutoff unit 132 may determine an average value of the first power amount data, the second power amount data, and the third power amount data. The power supply connected to the connector 110 may be selectively cut off by calculating and calculating the average value by comparing the average value with the reference value added to the standby power reference value set and stored in the memory unit 133 (S160).

In this case, the power cutoff unit 132 may determine whether the electronic device connected to the connector unit 110 is in a standby state or in use state by comparing the average value with the standby power reference value plus the reference value. For example, the power cutoff unit 132 may determine that the electronic device connected to the connector unit 110 is in a standby state when the average value is less than the standby power reference value plus the reference value, and the average value is the standby state. When the reference value is added to the power reference value, the electronic device connected to the connector 110 may be determined to be in use, but is not limited to the above example.

When the average value is less than the standby power reference value plus the reference value, the power cutoff unit 132 cuts off the power connected to the connector unit 110 (S170). That is, when the electronic device connected to the connector unit 110 is determined to be in a standby state because the average value is equal to or less than the standby power reference value and the reference value, the power cutoff unit 132 supplies power to the connector unit 110. Can be blocked (S170). Therefore, the method for shutting off the smart connector according to the embodiment of the present invention can easily prevent standby power consumption while the electronic device connected to the connector unit 110 is not used.

On the other hand, if the average value exceeds the standby power reference value plus the reference value, the power cutoff unit 132 maintains a state in which power is connected to the connector unit 110 (S150). That is, when it is determined that the electronic device connected to the connector unit 110 is in use when the average value exceeds the standby power reference value plus the reference value, the power cutoff unit 132 supplies power to the connector unit 110. You can stay connected.
