3 is a block diagram illustrating a configuration of a power control apparatus according to an embodiment of the present invention.

The power control device 300 includes a controller 310, a memory 320, a power driver 330, a schedule controller 340, a timer 341, a statistics unit 342, a power controller 343, a self-diagnosis and a failure. The display unit 350, the automatic recovery unit 360, and at least one sensor 371 to 373 may be included.

The memory 320 stores schedule data classified by date, day of week, or holiday. The schedule data may have different information on / off of each electric device according to the date, the day of the week, or the holiday. Because the entrance or exit of a person or a car is flexible, the schedule data must be adjusted according to the date, day of the week, or holiday to efficiently drive power to reduce power loss and extend the lamp life. To this end, in order to reflect the characteristics of a specific day such as a person or a car, the schedule data may be stored according to the date, the day of the week, or the holiday.

In addition, the schedule data includes a forced control period, and the forced control period is information for generating a power control signal in preference to a sensing signal received from at least one of the sensors 371 to 373. The power control device 300 may generate a power control signal according to any one of the sensing signal and the schedule data to turn on or off power for each electric device. The power control device 300 selects a time for frequent entry and exit, such as a commute time, as a forced control period, and in the forced control period, the lamp is turned on regardless of a detection signal to reduce power loss and extend the lamp life. Make sure

The schedule controller 340 may update the schedule data according to time information of the sensing signals generated from the at least one sensors 371 to 373 and statistical information based on the frequency of occurrence of the sensing signals. To this end, the timer 341 of the schedule controller 340 provides time information at the time of receiving the detection signal from at least one sensor. In addition, the statistics unit 342 of the schedule controller 340 generates statistical information by statistically generating a frequency of the detection signal for each time information.

As shown in FIG. 4, the occurrence frequency of the detection signal is 7 and the occurrence frequency of the detection signal is 30 at 8:00 and 9:00 AM. And, "9:00 ~ 10:00 PM" statistical information may be generated with the frequency of occurrence of the detection signal is 2. The occurrence of the detection signal is high when the movement of a person or a car is detected many times, which corresponds to frequent entry and exit. When the electric device is operated in accordance with the movement of a person or a car, the electric device is frequently turned on or off. As a result, power is wasted due to an increase in instantaneous starting current, and frequent power cuts can shorten the life of an electric device. In this case, schedule data for turning on the electric device at a time of frequent entry and exit may be generated to operate the electric device to reduce power loss and extend the life of the electric device even without a detection signal.

On the other hand, when the frequency of occurrence of the detection signal is low, the number of times when the movement of a person or a car is detected is small, so that the entrance and exit is sometimes performed. Instead of continuously operating the electric device, the electric device is operated only when there is a detection signal. Unnecessary power waste can be reduced.

As such, the statistics unit 342 updates the schedule data of the memory 320 based on the generated statistical information. In addition, the power controller 343 of the schedule controller 340 reads schedule data stored in the memory 320 and generates the power control signal according to the read schedule data.

The power driver 330 turns on or off power for each electric device according to the power control signal. For example, the power driver 330 may drive power for each electric device such as turning on a light, a fan, or turning off an air conditioner according to the power control signal.

In addition, the self-diagnosis and fault display unit 350 may include a memory 320, a power driver 330, a schedule controller 340, a timer 341, a statistics unit 342, and a power controller under the control of the controller 310. 343, the self-diagnosis and failure display unit 350, the automatic recovery unit 360, and the operation state of at least one or more of the at least one sensor 371 to 373 are checked and displayed. The self-diagnosis and failure display unit 350 transmits and receives a signal with the at least one device and transmits a signal to the corresponding device. When a signal is transmitted to the corresponding device but no signal is received from the corresponding device, it may be determined that the corresponding device is malfunctioning. The self-diagnosis and failure display unit 350 may display an operation state (normal operation or malfunction) according to each device through the determined determination result.

The automatic recovery unit 360 restores all or some of the functions of the corresponding device in case of failure according to the identified operation state. In an embodiment, the automatic recovery unit 360 may reset the power of the failed device to restore all or some functions of the corresponding device, or notify the administrator of the power control device 300 whether the corresponding device is broken or not. All or part of the functionality of the device may be restored.
