The present invention relates to a power cut-off system capable of automatically shutting off unnecessary standby power by sensing the ambient illuminance, and the power cut-off system includes a sensor unit 100 capable of detecting the surrounding environment, and an outlet provided with a shut-off system and a control unit 200 capable of controlling on/off of the multi-tap or the like, and a relay unit 300 capable of turning on/off the power of the outlet or the multi-tap.

Prior to the description, as a place where the power cutoff system is provided, it may be a single outlet or a multi-tap having a plurality of outlets, an electronic device that can be individually driven by a power source, etc. , it is to be noted in advance that it is not limited thereto.

The sensor unit 100 detects the multi-tap surrounding environment so that the control unit 200 can automatically cut off the power according to the surrounding environment.

The sensor unit 100 includes an illuminance sensor 110 capable of detecting illuminance of the surrounding environment.

The illuminance sensor 110 detects the illuminance of the surrounding environment. In particular, by detecting the indoor illuminance of a multi-tap provided in the room, when the user turns off the light switch when going out, it detects a change in ambient illuminance through this and presets in the control unit 200. When the illuminance value falls below the illuminance value or the illuminance change amount changes to more than a preset illuminance change amount, the controller 200 controls the relay unit 300 to automatically cut off the power.

On the other hand, the illuminance sensor 110 may be provided on the upper side of the multi-tap, but when provided only on the simple upper side, there is a risk that a shadow is formed on the upper side of the multi-tap due to obstacles such as furniture or objects provided in the room, and the surrounding illuminance is low. In addition, even when the illuminance sensor 110 provided on the upper side of the multi-tap is covered due to clothes or blankets thrown by the user, low illuminance is sensed, and there is a concern that the power may be automatically cut off even if the user does not want it.

Accordingly, the illuminance sensor 110 may be divided into a first illuminance sensor module 111 provided on the upper side of the multi-tap rather than a single illuminance sensor module 111 and a second illuminance sensor module 112 provided on the side of the multi-tap.

First, the first illuminance sensor module 111 may be provided on the upper side of the multi-tap to detect the amount of light and the illuminance directed toward the upper side of the multi-tap. The first illuminance sensor module 111 may sense the illuminance of the multi-tap surrounding environment together with the second illuminance sensor module 112 .

The second illuminance sensor module 112 may be provided on one side of the multi-tap or may be formed in a pair to be provided on both sides of the multi-tap, respectively. The second illuminance sensor module 112 may sense the amount of light and illuminance irradiated to the side of the multi-tap.

Therefore, the first illuminance sensor module 111 and the second illuminance sensor module 112 are spaced apart from each other and provided on the upper side and one side of the multi-tap, respectively, so that the surrounding environment of the multi-tap is not detected only by one illuminance sensor 110, but a plurality of By detecting the surrounding environment of the multi-tap from multiple angles with the illuminance sensors 110, the illuminance through the second illuminance sensor module 112 located on the side even if an obstacle, shade, etc. By detecting the difference, the controller 200 determines that an obstacle is located on the upper side of the multi-tap, thereby preventing automatic power off.

In addition, the sensor unit 100 is additionally provided with a power detection sensor 120 to detect the power consumption of the connected electronic device.

For example, the power consumption of a computer or data output device (audio, speaker, etc.) connected to a multi-tap varies according to use in addition to the power used for simple operation. Accordingly, when the user stops using the computer or the data output device and goes out or is absent, a slight change in power consumption is detected to detect the absence of the user.

Through this sensor unit 100, not only the illuminance but also the amount of power consumption can be sensed to detect the absence of the user.

In particular, in the case of motion detection sensors among the existing human body detection sensors, the power is automatically cut off when the user is still, so there is a problem due to unwanted power cut off. Since there is a risk of detecting heat, it is difficult to properly cut off the power. Therefore, through the sensor unit 100 including the illuminance sensor 110 and the power detection sensor 120 according to the present invention, even if the user around the multi-tap does not move, automatically It is possible to prevent the power from being cut off, and it is possible to prevent the power from being cut off due to a change in illuminance due to a simple obstacle by detecting the illuminance change that occurs when the user turns off the indoor light when the user is absent from the upper side and the side.

The control unit 200 relates to an MCU that determines whether to cut off the power of the multi-tap through the sensor value detected by the sensor unit 100, and controls the relay unit 300 accordingly, the control module 210, the conversion module ( 220 ) and a memory 230 .

The control module 210 is connected to the relay unit 300 to control the power driving of the multi-tap, and a determination unit 211 capable of determining whether the power is cut off by determining a sensor value detected from the sensor unit 100 . ) is included.

The determination unit 211 determines whether the ambient illuminance of the multi-tap falls below the pre-stored illuminance value or the power consumption of the electronic device connected to the multi-tap is higher than the written power consumption change value according to the illuminance value and power consumption stored in the memory 230. When there is a large change, the control module 210 operates the relay unit 300 to cut off the power.

At this time, the determination unit 211 receives the sensor values (ie, illuminance values) received from the first illuminance sensor module 111 and the second illuminance sensor module 112, respectively, and compares them to the first and second illuminance sensor modules ( 111 and 112), the relay unit 300 is operated only when it falls below the pre-stored illuminance value.

In addition, in the case of the power detection sensor 120, since the power consumption of the electronic device may not occur due to the absence of the user, only the sensor value received from the power detection sensor 120 is determined so that the relay unit 300 is not operated. control

That is, the relay unit 300 is controlled based on the sensor value detected through the illuminance sensor 110, but the power cut-off through the relay unit 300 is performed with reference to the sensor value detected through the power detection sensor 120. make it happen

In addition, the control module 210 additionally includes a count unit 212 to receive the sensor value received from the sensor unit 100 for a certain period of time and finally supply power from the relay unit 300 when there is no change in the surrounding environment. to block it

For example, the sensor unit 100 detects an instantaneous change in illuminance by simply turning on the ambient light, that is, blocking the light that is not intended by the user, and directly controls the relay unit 300, and through this, the power can be cut off. have.

Therefore, when the sensor value transmitted from the sensor unit 100 is maintained at the same value for a certain period of time, the count unit 212 controls the operation of the relay unit 300 by finally determining that the user is away from the indoor lighting and , so that the power can be turned off through this.

In addition, on the contrary, when the ambient illuminance is equal to or greater than a preset setting value (that is, the illuminance value), it is recognized that the user has entered the room, and through this, the relay unit 300 is automatically driven (ON) to automatically connect the multi-tap and the multi-tap. Standby power can be supplied to connected electronic devices so that they can be operated quickly.

The conversion module 220 is made of an AC/DC converter, and serves to supply the converted current to the control module 210 . That is, the commercial AC power is rectified and converted into a stable DC voltage.

The memory 230 stores a set value serving as a reference so that the determination unit 211 determines whether to control the relay unit 300 (ie, whether to cut off the power) by determining the sensor value received from the sensor unit 100 . Therefore, the memory 230 may pre-store the expected ambient environment illuminance value, power consumption change value, and the like when the user is away.

In this case, the setting value stored in the memory 230 can be easily changed through the setting module 240 to be described later.

On the other hand, the relay unit 300 may be operated and power may be cut off according to a change in the illuminance of the surrounding environment. Since the average illuminance varies depending on the indoor environment in which the multi-tap is provided, the setting value stored in the memory 230 needs to be changed. exists

For example, in the case of a multi-tap installed in a dark room or a dark reading room, since the average illuminance is low, the ambient illuminance is determined to be low with the illuminance value stored in the memory 230, and there is a risk that the power is continuously cut off.

Therefore, when the user directly installs a multi-tap equipped with a blocking system, a setting module 240 that can adjust the setting value according to the installed environment, and the user terminal M and the blocking system so that the user can directly adjust the setting value A communication module 250 capable of interworking may be additionally provided in the control unit 200 .

The setting module 240 can be controlled through a user terminal connected to the blocking system through the communication module 250, and when the setting module 240 is operated through the user terminal M, the sensor unit 100 for a certain time. The relay unit 300 automatically cuts off the power even in a rather dark surrounding environment by detecting the ambient light in can be prevented

The communication module 250 is connected to the user terminal (M) through wireless communication, etc. to interwork with the blocking system provided in the multi-tap, so that the setting module 240 detects the average illuminance through the sensor unit 100 and sets the value to reset or directly control the control module 210 through the terminal M to control the relay unit 300 .

In addition, by checking the state of the relay unit 300 through the terminal (M), the relay unit 300 can be turned on/off directly from the outside.

The relay unit 300 is a relay switch provided in the multi-tap, and when the sensor unit 100 detects a case below the set value (illuminance value, etc.) set in the memory 230, it receives control from the control module 210 and receives the control from the multi-tap. It is possible to block the standby power flowing to the

In the power cut-off system having the above-described configuration, the sensor unit 100 detects the ambient illuminance to detect the absence of a person, and the control unit 200 receiving the sensor value from the sensor unit 100 determines the sensor value and relays By controlling the on/off of the unit 300, the power is automatically cut off to prevent unnecessary standby power consumption and safety accidents caused by electricity.

In addition, the illuminance sensor 110 composed of the first and second illuminance sensor modules 111 and 112 is provided to detect the illuminance of the upper and side surfaces rather than one-dimensionally to detect the illuminance change in the surrounding environment, thereby illuminance caused by indoor obstacles, etc. It does not detect any change, so it has the effect of preventing the power from being automatically cut off due to simple light blocking.

In addition, the illuminance change standard can be set according to the average illuminance of the surrounding environment in which the user is directly installed by interworking with the user terminal M through the communication module 250, and the user directly controls the on/off of the relay unit 300 from the outside. It has effects that you can directly control.
