<Example 1>

Referring to FIG. 1, the IoT smart LED lighting control system 100 for reducing standby power and low power according to an embodiment of the present invention includes a lighting unit 110, a control unit 120, a communication unit 130 and a power supply unit 140. can do.

The lighting unit 110 includes at least one LED light, and the LED light includes at least one transmission module and a reception module, and the reception module receives a signal transmitted from the transmission module, but from the reception module. It is possible to detect whether or not there is interference in a received signal.

More specifically, a signal of a predetermined frequency is transmitted through the transmission module provided in the LED module, and the reception module receives the signal transmitted from the transmission module, but an obstacle is between the transmission module and the reception module. If located, interference will occur in the signal.

Accordingly, the lighting unit 110 may detect whether or not interference occurs in a signal collected through the receiving module of the LED light.

As an example, the IoT smart LED lighting control system 100 for reducing standby power consumption includes a sensor unit including at least one motion sensor for detecting the motion of the user and at least one illuminance sensor for measuring the illuminance of a predetermined space. (not shown) may be further included.

Meanwhile, the control unit 120 performs at least one of lighting control, dimming control, and color toning control of the LED lighting, and the communication unit 130 controls lighting and dimming of the lighting unit 110 from a predetermined user terminal. A remote control signal including at least one of color matching control may be received, the received remote control signal may be transmitted to the control unit 120, and the power supply unit 140 may supply power to the control unit 110.

More specifically, referring to FIG. 2 , the control unit 120 sets one of the LED lights provided in the lighting unit 110 as a transmission mode when N (N>1), and sets N-1 LED lights. The role setting unit 121 for setting the receiving mode, analyzes the interference waveform of the signal received from the LED module set to the receiving mode to determine whether the received signal satisfies a preset reference range, and determines whether the user's A user occupancy determination unit 122 for determining whether a room is occupied, an automatic lighting control unit 123 for automatically controlling the lighting unit 110 based on preset conditions when it is determined that the user is in a room, and reception from the user terminal It may include a manual lighting control unit 124 for manually controlling the lighting unit 110 based on the remote control signal.

At this time, the user presence determination unit 122 may determine whether the user is present by determining whether the signal received from the LED module is included in a preset motion detection section.

As shown in FIG. 3, there is a difference between a waveform 301 corresponding to the motion of the user and a waveform 302 corresponding to the motion of a companion animal, and based on the difference between the two waveforms, the user motion detection period is determined. can be determined

Therefore, when the waveform of the signal received by the lighting unit 110 is included in the motion detection section, the user occupancy determination unit 122 may determine that the user is in a space where the lighting unit 110 is provided. there is.

For example, when the user presence determination unit 122 needs to detect the movement of an infant or companion animal whose movement is relatively minute and the degree of signal interference is not large, the motion detection section is adjusted to adjust the infant or companion animal. movement can be sensed.

In addition, the user presence determination unit 122, when the number of the LED lights set to the reception mode is at least three, the LED light provided in the closest position to the user can be determined as the scanning light 12 there is.

For example, as shown in FIG. 4, at least two or more LED lights 10 are installed in one space, located between the LED lights 11 set to the transmission mode and the LED lights set to the reception mode Based on the location of the user, the LED light set to the receiving mode receives signals of different waveforms, and the more severe the interference of the signal received from the LED light, the more the user is considered to be present in a position close to the LED light. can judge

Therefore, when the number of LED lights is two, the user presence determination unit 122 determines that the LED light set to the reception mode is the scanning light because one LED light is set to the reception mode, and the LED light is set to three LED lights. In the case of more than one, it is possible to determine one of the injection lights 12 by comparing the waveforms of at least two or more LED lights set to the reception mode.

In addition, the lighting automatic control unit 123 separates and controls the scanning light and the other LED lights excluding the scanning light, and a separate control mode that separates and controls the scanning light and other LED lights excluding the scanning light. It is possible to control the lighting unit 110 by dividing it into an integrated control mode for controlling the lighting unit 110 .

At this time, the control mode of the lighting unit 110 is automatically controlled based on the control mode setting input from the user terminal.

More specifically, when a separate control mode is set from the user terminal, the scanning lighting is automatically turned on with a preset color and brightness, and other LED lights excluding the scanning lighting are based on settings input from the user terminal. is turned on in mood light mode, or other LED lights may not be turned on.

In addition, when the integrated control mode is set from the user terminal, all LED lighting including the lighting for scanning may be automatically turned on with preset colors and brightness.

Therefore, it is possible to collectively control all lighting provided in a space set according to the user's purpose of use, or separate and control only the lighting of a partial area where the user is located.

As another example, the controller 140 may set an operating time of the lighting unit 110 based on a signal input from the user terminal.

On the other hand, as shown in FIG. 5, the communication unit 130 searches for at least one IoT device located in a preset space, and connects the IoT device and the lighting unit to control the IoT device linking unit 131. Including, the IoT device interlocking unit 131 is a pairing setting unit 510 that performs a pairing operation between the lighting unit 110 and the IoT device through the user terminal. The IoT device and the lighting unit 110 are paired. In this case, a command setting unit 520 for setting at least one short command through the user terminal, a first linkage for detecting an operating state of the IoT device and controlling the lighting unit 110 in response to the short command. It may include a second interworking controller 540 that senses operating states of the control unit 530 and the lighting unit 110 and controls the IoT device in response to the short command.

For example, the IoT device includes a Bluetooth speaker, an air purifier, a smart TV, a window opening and closing device, and the like, and the IoT device can perform a specific operation based on the position, brightness, color, and lighting state of the LED light, , The LED light may perform a specific operation based on the control state of the IoT device.

Accordingly, the user may set activity routines of various IoT devices by controlling only lighting.

Referring to FIG. 5 , the power supply unit 140 measures standby power when the operating state of the power supply unit 141 for supplying power to the control unit 120 and the lighting unit 110 are OFF. The measuring unit 142 and the power saving signal generating unit 143 for generating a power saving mode control signal when the standby power measured by the power measuring unit 142 exceeds a preset maximum standby power may be included.

In addition, when the power saving mode control signal is generated, the controller 120 drives a standby power control element that generates a frequency of a preset duty ratio to control an off-time during which power is not supplied to the lighting unit 110. It may further include a standby power blocking control unit (not shown).

On the other hand, the power supply unit 140 of the IoT smart LED lighting control system 100 for reducing standby power is a standby power sensing verification unit (not shown) for determining the reliability of the standby power data measured by the power measuring unit 142. ) may further include.

More specifically, the standby power sensing verification unit (not shown) determines the reliability of the standby power amount calculated based on the standby power sensing data collected from the power measurement unit 142 of the power supply unit 140; , When the average value (A _err ) calculated by the following [Equation 1] is greater than the preset limit value (S _err ), it is determined that an error has occurred in the standby power sensing data collected from the power measuring unit 142 can do.

[Equation 1]

Here, Aerr is the average error of the standby power sensing data, Taver is the overall average of the standby power sensing data, Paver is a partial average of n standby power sensing data, and Tσ is the total standard deviation of the standby power sensing data it means.

More specifically, T _aver is the overall average of the standby power sensing data, and means a value obtained by calculating the overall average of the standby power sensing data generated during a predetermined period (ex. one month), and T _σ is the It means a value obtained by calculating the total standard deviation of the standby power sensing data for a predetermined period (eg, one month).

In addition, P _aver is a partial average of n standby power sensing data among standby power sensing data generated during a preset period (eg, one month), and collects standby power sensing data collected from the power measuring unit 142 In the process of doing this, a preset number (n) of standby power sensing data is collected, and the average of the preset number (n) of standby power sensing data is calculated. can be referred to as average.

At this time, if the estimated average value is calculated with 95% reliability using a partial average, the estimated average value (μ) is have a range.

Therefore, the average error (A _err ), which is the difference between the upper or lower limit of the estimated average value (μ) and the overall average (T _aver ), can be calculated as in [Equation 1] above.

Therefore, if the average error (A _err ) calculated by [Equation 1] is greater than the preset limit error (S _err ), the standby power sensing data collected through the power measurement unit 142 is the power measurement unit Since at least one power measuring sensor provided in 142 is highly likely to be erroneously input due to a failure of the power measuring sensor for measuring standby power, the standby power collected through the power measuring unit 142 when the above condition is satisfied. Sensing data may be determined to be unreliable.

On the other hand, the standby power sensing verification unit (not shown) compares the average value (A _err ) calculated by [Equation 1] and a preset limit value (S _err ) in order to determine whether there is an error in the standby power sensing data At the same time, the temperature of the power supply unit 140 is measured to determine whether the measured temperature is out of a preset range, whether the standby power sensing data shows a pattern that is periodically repeated within a preset interval size, the power supply unit 140 By measuring the humidity around the humidity, whether the measured humidity is outside the preset range, by analyzing the ratio of the operating time and non-operating time of the power measuring unit 142, whether the ratio is out of the preset ratio range, etc. It may be determined that an error has occurred in the real-time image data when at least one of the above conditions is satisfied.

Hereinafter, specific details of the error determination methods will be described in detail.

First, in order to measure the temperature of the power supply unit 140 and determine whether the measured temperature is out of a predetermined range, a temperature sensor is separately provided within a predetermined distance from the power supply unit 140, and the temperature sensor detects the temperature through the temperature sensor. The temperature of the power supply unit 140 may be monitored in real time. This uses the technical principle of maintaining the heating temperature within the allowable range (preset heating temperature range) if the power supply unit 140 is operating normally, and if the heating is excessive or there is no heating, an overload occurs. In that case, it can be determined that an error has occurred in the power supply unit 140, which can be estimated that an error has occurred in the standby power sensing data.

Next, in order to determine whether there is an error in the standby power sensing data, it is possible to monitor whether or not the real-time image data shows a pattern that is periodically repeated within a preset interval size, which means that the power supply unit 140 receives an abnormal signal. If it is applied, it uses the technical principle that standby power sensing data values can be repeatedly output in a specific pattern within a predetermined interval size. At this time, the preset section size may be determined according to [Equation 2] below.

[Equation 2]

A _range = {(T _aver + D _max ) - (T _aver - D _max )}*0.3

A _range is a preset interval size, T _aver is an overall average for a preset period, and D _max means a maximum deviation during a preset period.

For example, if the overall average for a preset period is 70 and the maximum deviation is 20, A _range is 12, so values that are periodically repeated within a range where the difference between the maximum and minimum values does not exceed 12 are output (ex. 52, 62 If similar values such as , 52, 62, 53, 62, 52, 63 are repeatedly output), it can be assumed that an error has occurred in the standby power sensing data due to an abnormal abnormal signal being applied to the power supply unit 140.

Next, in order to measure the humidity of the power supply unit 140 and determine whether the measured humidity exceeds a predetermined value, a humidity sensor is separately provided within a predetermined distance from the power supply unit 140, and the humidity sensor Through this, the humidity of the power supply unit 140 can be monitored in real time. This is based on the technical principle that when moisture flows into the power supply unit 140, it operates abnormally, and when the humidity exceeds a predetermined value, it can be assumed that moisture has flowed into the power unit 140. Therefore, in this case, it can be determined that an error has occurred in the power supply unit 140, and it can be estimated that an error has occurred in the standby power measurement data.

Finally, by analyzing the ratio of the operating time and non-operating time of the power measuring unit 140, it is possible to determine whether the ratio is out of a predetermined ratio range, and according to the result, the standby power sensing data It can be judged that an error has occurred.

For example, if the power measurement unit 142 is set to measure power by 0.1 seconds every second for power saving, the ratio of operating time and non-operating time is 10: 1, but as a result of analysis through real-time monitoring If the ratio is reversed to 1: 10 or changed to a significantly different ratio (eg, ratio change of 30% or more), it can be determined that the power measurement unit 142 malfunctions and an error occurs in the standby power sensing data.

As described above, in one embodiment of the present invention, the standby power sensing verification unit (not shown) may determine whether the standby power sensing data has an error in consideration of a plurality of fault diagnosis methods, and the following [Equation 3] It may be finally determined by the S _total value reflecting all of the multiple failure diagnosis methods as shown in FIG.

[Equation 3]

S _total = W1*R _aver + W2*R _tem + W3*R _hum + W4*R _rep + W5*R _rat

Here, S _total is the sum _of a plurality of error judgment values, R _aver is the error judgment value ( _error one of 0 and 1 depending on whether or not), R _tem is a value determined by whether the temperature is out of the preset range (one of 0 and 1 depending on whether or not there is an error), R _hum is a value determined by whether the humidity is out of the preset range (one of 0 and 1 depending on whether there is an error), R _rep is a value that determines whether or not there is an error depending on whether a repetitive pattern appears (one of 0 or 1 depending on whether or not there is an error), R _rat is a value that determines whether or not there is an error by analyzing the ratio of operating time to non-operating time (error one of 0 or 1), W1 means R _aver item weight, W2 means R _tem item weight, W3 means R _hum item weight, W4 means R _rep item weight, W5 means R _rat item weight, respectively. .

For example, if S _total is 4 or more, it can be preset that the standby power sensing data has an error, and if the heating temperature is a very important parameter, W2 is preset to 3, and W1, W3, W4, and W5 are All can be preset to 1.

Under these conditions, as a result of monitoring errors according to the above multiple fault diagnosis methods, if R _aver is 1, R _tem is 1, R _rep is 0, R _hum is 0, and R _rat is 0, S _total is 4 Therefore, it can be finally determined that there is an error in the standby power sensing data.

For example, when the standby power sensing verification unit (not shown) determines that there is an error in the power supply unit 140, a notification transmission signal is generated to transmit a message requesting inspection to a predetermined user terminal, and the communication unit ( 130) may be forwarded.
