FIG. 1 is a diagram illustrating an operating system such as smart security using a smart network technology according to an embodiment of the present invention.

1, an operating system such as smart security using smart network technology includes first to fifth active power control servers (APCS) 10, 20, 30, 40, 100 and a plurality of smart Security lamps 200. [0034] FIG.

The first to fifth APCSs 10, 20, 30, 40, and 100 may be constructed in a hierarchical structure for managing power by region, and may communicate through an Internet network such as Ethernet or Wi-Fi. The first APCS 10 is a top layer L1, that is, a country corresponding to the first layer, a second APCS 20 is an angle corresponding to the second layer L2, a third APCS 30 is a third layer The fourth APCS 40 corresponds to the fourth layer L4 or the fifth APCS 100 corresponds to the lowest layer or the fifth layer L5 And may be constructed on a per-unit basis.

The first to fifth APCSs 10, 20, 30, 40, and 100 may actively control power to be supplied to the plurality of smart security lamps 200.

In addition, the first to fifth APCSs 10, 20, 30, 40, and 100 may exchange predicted power usage information in cooperation with servers in other regions, and may distribute power usage.

In addition, the first to fifth APCSs 10, 20, 30, 40, and 100 can adjust electricity consumption by region in real time, and can adjust the brightness of the smart security lamps 200, It is possible to prevent a power failure in the area where the security lamp 200 is installed.

FIG. 2 is a diagram illustrating a communication scheme between hierarchical first to fifth APCSs 10, 20, 30, 40, 100 according to an embodiment of the present invention.

In FIG. 2, L1 denotes a first APCS 10, L2A, L2B and L2C, which are implemented as state qualification in the smart security lamps, and second APCSs 20, L3B1, L3B2 and L3B3, The fourth APCSs 40, L5B111, L5B112, L5B113 and L5B114, which are constructed in units of towns or villages belonging to L3B1 at the time of L3B1, And the fifth APCSs 100 constructed in the same unit. Therefore, in the following, Ln (n is any one of 1 to 5) and nAPCS can be used in the same meaning.

Referring to FIG. 2, the first to fifth APCSs 10, 20, 30, 40, and 100 of the operating system, such as smart security, And can be constructed in a hierarchical structure on a regional basis. In other words, APCS can be given rank (Level 1 ~ Level 5) on a regional basis.

The first to fifth APCSs 10, 20, 30, 40, and 100 are interlocked with the same APCS in the same area in order to prevent power failure of the plurality of smart security lamps 200 while maintaining the security function due to hacking. At the same time, even if a particular APCS becomes insoluble by hacking, data can be recovered while being quickly blocked with a specific APCS.

For example, the first to fourth APCSs 10 to 40 corresponding to L4 or higher layers can not directly control the smart security system 200, but only provide functions to secure the reliability and safety of data can do.

Therefore, in order to secure such data security, that is, for the purpose of security enhancement, communication between the first to fifth APCSs 10, 20, 30, 40, 100 is not possible in the same rank, do.

That is, direct communication between the APCSs of the same layer is impossible, and data can be shared with the APCS of the same layer of the neighbor through the upper layer for communication. At this time, the APCS requesting data sharing requests the APCS of the upper layer to authenticate itself, and then requests data sharing to the desired APCS. For example, L4B11 can request data to L4B32 in the order L4B11 L3B1 L3B1 L2B L3B3 L4B32.

Also, the APCS of a specific layer can not request data of an upper layer to its upper layer, but can report data and execute an instruction from a higher layer. For example, L4 can not request L3 data from L3, and L5 reports data to L4 and executes the command, but it is impossible to request data from other APCS.

Also, the first to fifth APCSs 10, 20, 30, 40, and 100 according to the embodiment of the present invention use a prediction algorithm using a deep learning technique based on big data in order to secure reliability and accuracy of data The power consumption can be predicted and countermeasures can be prepared.

More specifically, the first to fourth APCSs 10 to 40 execute a prediction algorithm based on data (for example, total power consumption) accumulated in their direct lower layer APCS, so that future long- And the power failure prediction can be performed. That is, for example, L3B1 can derive highly accurate prediction results based solely on data of L4B11, L4B12, and L4B13.

In addition, the fifth APCS 100 can perform only the control function of the LED module 300, the warehouse information and the real-time power consumption collection function. In addition, the fifth APCS 100 can be constructed with redundancy in preparation for a failure.

3 is a diagram for explaining a power management boundary value.

All of the first to fifth APCSs 10, 20, 30, 40, 100 shown in FIGS. 1 and 2 can store and manage the power management boundary value as shown in FIG. 3 for power consumption and power outage prediction.

Referring to FIG. 3, W1 to W6 are power management boundary values, and the unit is the total power consumption. For each power management boundary value, the power assist measures of the first to fifth APCSs 10, 20, 30, 40, Is defined. Further, the second to fourth APCSs 20 to 40 can share data by communicating with other power management servers (for example, an electric vehicle, a drone, and a robot management server) in the area in charge.

On the basis of the fifth APCS 100, when modifications are made to the values of W1 to W6 or W1 to W6 boundary-specific behavior guidelines defined in the fifth APCS 100, they are collected from L4 in real time. Substantially, the values of W1 to W6 or the behavioral guidelines to be changed can be varied from L2 to L3 -> L4 -> L5 at the top level from time to time.

When the cumulative total power usage reaches W1, the warning level occurs, and when it reaches W4, Severe Warning Level occurs. For example, the third APCS 30 predicts that the probability of occurrence of a power outage is high when the cumulative amount of power usage received from the plurality of fourth APCSs 40 managed by the third APCS 30 exceeds W6, . Accordingly, the second APCS 20 can request power supply assistance to other nearby APCSs to prevent power failure.

The values of W1 through W6 may be different for each of the first through fifth APCSs 10, 20, 30, 40, and 100. This is because the size of the area covered by each region differs and the amount of power available varies.

Referring to FIG. 1 again, the fifth APCS 100 can collectively broadcast a power control signal to a plurality of smart security lamps 200 located in a jurisdiction area using an available radio frequency band of a broadcast band have.

The plurality of smart security lights 200 are located in the jurisdiction of the fifth APCS 100 and adjust the illuminance based on the intensity control signal from the fifth APCS 100 and periodically detect the power consumption to detect the fifth APCS 100, Lt; / RTI >

The fifth APCS 100 determines the intensity control signal for adjusting the illuminance of the plurality of smart security lamps 200 based on the total power consumption amount of the power consumption information received from the plurality of smart security lamps 200, And transmit the determined illumination control signal to the plurality of smart security lamps 200. The fifth APCS 100 may be an operating server such as smart security for directly managing the smart security lights 200 in the jurisdiction and controlling power supply. Hereinafter, the fifth APCS 100 is referred to as an operating server such as smart security. The size of the jurisdiction may be determined by the communication distance of the radio frequency band.

4 is a block diagram illustrating an operational server 100, such as smart security, using smart network technology in accordance with an embodiment of the present invention.

The operational server 100, such as the smart security system shown in FIG. 4, may be the fifth APCS 100 described with reference to FIGS.

4, the operation server 100 includes a first communication interface unit 110, a second communication interface unit 120, a user interface unit 130, a flash memory (not shown) 140, a memory 150, a DB 160, a USB interface 170, a universal asynchronous receiver / transmitter (UART) unit 180, and a server processor 190.

The first communication interface unit 110 may communicate with a plurality of smart security devices 200 using a radio frequency band of a broadcast band. In detail, the first communication interface unit 110 may transmit an illumination control signal for controlling brightness to a plurality of smart security lamps 200, and may receive power consumption information from the plurality of smart security lamps 200.

The first communication interface unit 110 may include a communication circuit using a COFDM (Coded Orthogonal Frequency Division Multiplexing) modulation scheme for a communication distance of about 3 km between the operating server 100 and the smart security lights 200 Or use the LoRA module.

The broadcasting band, that is, the TV band, is allocated from 54 MHz to 800 MHz, of which 85 MHz to 174 MHz and 218 MHz to 470 MHz are used for communication other than TV. In the embodiment of the present invention, a radio frequency band of the 262 MHz band allowed by the country may be used, and the present invention is not limited to this frequency band.

For example, in the case of using 262 MHz, the communication distance between the operating server 100 and the smart security lamps 200 is about 3 km and the communication distance is about 700 m to 1 km. 100 and the smart security lamps 200 may be changed.

In the embodiment of the present invention, the first communication interface unit 110 may use not only 262 MHz, but also 447 MHz wireless communication or digital TV white space, and wireless communication technologies such as ZigBee and LoRa may be used.

The second communication interface unit 120 may be configured such that whenever the total power consumption, which is the sum of the power consumption received from the plurality of smart security devices 200, reaches one of a plurality of power usage threshold levels, , The fourth APCS 40) through the Internet network.

The user interface unit 130 may serve as an interface for transferring commands or data input from a user to another component (s) of the operation server 100, such as smart security.

The flash memory 140 may store various data generated when the operating server 100 is operated, such as smart security, and power consumption information received from the plurality of smart security lamps 200.

The memory 150 may include instructions or data related to the components 110-190, one or more programs and / or software associated with the components 110-190 to implement and / or provide the operations, functions, and the like provided by the operational server 100, , An operating system, and the like.

The program stored in the memory 240 may include a brightness control program that can control the brightness of the plurality of smart security lamps 200. In addition, the memory 150 may store a mapping table in which identification information of the target smart security lamps to be down-adjusted and the illumination ratio to be down-adjusted are mapped to the power usage threshold level and the illuminance level for the entire power consumption.

[Table 1] is an example of a mapping table stored in the memory 150).

Total power consumption (W) Power usage threshold level Downlight Ratio Targeted smart security, etc. 0 &lt; W < W1 safety Maintain current illumination none W1? W <W2 W1, Warning Level Wait for Action command The first group W2? W <W3 W2, Warning Level 10% The second group W3? W <W4 W3, Warning Level 20% Group 3 W4? W <W5 W4, Severe Warning Level 40% Group 4 W5? W <W6 W5, Severe Warning Level 50% Group 5 W6? W <W7 W6, Severe Warning Level 70% Group 6 W7? W W7, Blackout Level blackout Blackout

In Table 1, the first group is the identification information of the smart security lights predetermined to lower the illuminance when the total power consumption corresponds to W1? W <W2. Thus, as the total power consumption increases, the number of smart security lights belonging to the mapped group may also increase.

The DB 160 stores identification information of the plurality of smart security devices 200 managed by the operating server 100 such as smart security, installed location information, and the amount of power consumption received from the plurality of smart security devices 200, &Lt; / RTI &gt;

The USB interface unit 170 provides an interface with a USB device.

The UART unit 180 may be responsible for data conversion and transmission of the operational server 100, such as smart security.

The server processor 190 may execute one or more programs stored in the operating server 100, such as smart security, to control the overall operation of the operating server 100, such as smart security.

For example, the server processor 190 can execute control of the illumination control program stored in the memory 150, and can be controlled by individual IDs, groups, and postal codes (Zip codes) of the respective smart security devices 200, It can be controlled by the schedule function. The basic data that the server processor 190 can control the smart security lamps 200 are brightness and color, and blink function, LED pattern function, music function, and the like can be implemented by combining basic data.

In addition, the server processor 190 may map each power consumption received from the plurality of smart security devices 200 to the identification information of the smart security device and the date, and store the mapped data in the DB 160.

In addition, the server processor 190 calculates the total power consumption W by collecting the power consumption amount received from the plurality of smart security lights 200 stored in the DB 160, calculates the total power consumption W, Can be compared.

As a result of the comparison, if the total power consumption corresponds to one of the plurality of power usage threshold levels in Table 1, the server processor 190 determines that the downlight intensity ratio mapped to the target smart security lights mapped to the corresponding power usage threshold level The first communication interface unit 110 may be controlled to transmit the illumination control signal for adjusting the illuminance to the lower level.

For example, if the total power consumption is in the range of W2 < W &lt; W3, since the power usage threshold level is 'W2, Warning Level', the server processor 190 belongs to the second group of the plurality of smart security lights 200 Smart security lamps can be processed to transmit an illumination control signal to lower the illumination by 20%.

In addition, if it is determined that the power usage threshold level corresponding to the total power consumption amount in the jurisdiction is equal to or greater than W1, the server processor 190 determines that the specific power usage threshold level has been reached to the upper layer operating server, i.e., the fourth APCS 40 The first communication interface unit 120 may control the second communication interface unit 120 to transmit the boundary level arrival message through the Internet network.

Accordingly, the upper layer operating server 40 can confirm the total power consumption and power management boundary level included in the received boundary level arrival message, and can respond to the defined power level countermeasure against the identified boundary level. For example, the upper layer operating server 40 requests the power supply to the third APCS 30 corresponding to its upper layer or informs the operation server 100 of smart security or the like, can do.

6, the communication front end module 510 includes an ESD filter 511, an FM (Frequency Modulation) filter 512, a tuner 513, an LPF (Low Pass Filter) 514, a BPF (Band Pass Filter) 515, a microcomputer 516, a first LPD regulator 517, a second LDO regulator 518, and an antenna connector 519.

The ESD filter 511 is provided at an input terminal of the antenna and is connected to an input terminal of the antenna so as to protect the communication front end module 510 or the circuit of the communication device 500 from external surge and electrostatic discharge (ESD) ESD diodes can be used.

The FM filter 512 performs low-frequency noise filtering on a signal input from the antenna or the ESD filter 511.

The tuner 513 can select a set radio frequency band, for example, a 262 MHz band, of the received signals. To this end, the PCB (Printed Circuit Board) pattern distance between the antenna input terminal of the communication front end module 510 and the RF tuner 513 may be designed to be 10 mm or less. A GND Cooper is installed around the PCB pattern to prevent noise . If the distance between the external antenna and the tuner 513 becomes long, the external antenna and the tuner 513 are connected using the shielded RF cable, and the loss in the entire cable is 3 dB or less May be used.

The LPF 514 can block the inflow of power supply noise by applying Low Pass filtering to the signal input from the tuner 513. [

The BPF 515 may include a time constant circuit for converting a signal of a radio frequency band from which power supply noise has been removed to an intermediate frequency (IF). To do this, the power pattern or other signal pattern should not be placed within 3 mm of the PCB circuit of the BPF 515.

The microcomputer 516 may control the overall operation of the communication front end module 510. For example, the microcomputer 516 may forward the incoming intermediate frequency to the processor 560 such as security.

The communication front end module 510 or the communication device 500 may use a 3V power source to minimize power source noise. Accordingly, the first LPD regulator 517 can output the 5V power input from the power supply device 400 as a dedicated power supply for the communication circuit of 3V so that the 3V power supply can be completely separated from other circuits.

The second LDO regulator 518 can output the 5V power input from the first LDO regulator 517 as a power source dedicated to the tuner 513 of 1.2 V so as to be completely separated from other circuits.

The antenna connector 519 may be an SMA (Subminiature A) type connector. The SMA connector must be shielded and the RF signal input pattern can be impedance matched.

The UP converter 505 may convert an intermediate frequency band signal input from the microcomputer 516 into an RF band when the smart security system 200 transmits data to the operation server 100 such as smart security have. The signal converted into the RF band is filtered by the ESD filter 511, and then transmitted to the operation server 100 through the antenna, such as smart security.

Referring again to FIG. 5, the memory 520 may include instructions or instructions related to the components 510 - 550, 300, 400 to implement and / or provide the operations, functions, Data, one or more programs and / or software, an operating system, and the like.

The illumination temperature of the LED module 300, the illumination level changed according to the illumination control signal, and the power consumption of the LED module 300 detected by the power supply device 400 are stored in the memory 520 in the RTC 530 Can be cumulatively stored together with the time information confirmed by the user. To this end, the memory 520 may include a DDR (Double Data Rate) storage medium (not shown) and a flash memory (not shown).

The LED controller 540 may be an LED driver that drives the LED module 300 according to a control signal of the processor 560, such as security. For example, if the control signal is a DIMING control signal, the LED controller 540 drives the LED module 300 so that the LED elements perform the DIMING effect according to the period set in the DIMING control signal.

Further, if the control signal is the illumination control signal, the LED controller 540 drives the LED module 300 to adjust the brightness to the illumination level set in the illumination control signal. When the illuminance level set in the illuminance control signal is lower than the previous illuminance level, the power consumption is reduced.

Also, the LED controller 540 can supply the power inputted from the power supply device 400 through the power conversion unit 550 to the LED module 300.

The power conversion unit 550 converts the power input from the power supply device 400 into a low power. For example, since the communication device 500 needs to use low power such as 1V, 1.2V, 1.5V, 1.8V, 2.5V, and 3V, the power converter 550 converts 5VDC to a set low power .

In addition, the power converter 550 may receive a relatively high power (e.g., 50VDC) as compared with 5VDC, convert the power to 48VDC, and supply the power to the LED controller 540. [

The security processor 560 may control the overall operation of the smart security light 200 by executing one or more programs stored in the memory 520. [

For example, the processor 560, such as security, may process the control signal input from the communication front-end module 510 and transmit the signal to the LED controller 540. The processor 560 may control the communication front end module 510 to transmit the power consumption of the smart security light 200 input from the power supply device 400 to the operational server 100 such as smart security have.

In addition, the processor 560, such as security, may collect the warehouse information of each smart security system 200, determine whether the warehouse information is available, and report the information to the upper hierarchy operating server 40.

A method for determining whether the processor 560 is secure or not is as follows. First, it is determined whether communication between the CPU of the processor 560 and the memory 520 is normal. Second, whether the communication between the CPU of the processor 560 and the communication front-end module 510 is normal, such as security, It is determined whether the operation of the module 300 is normal.

In order to determine whether the operation of the LED module 300 is normal, the processor 560, such as security, empirically grasps the temperature sensor value for each step of dimming (brightness or illuminance), calculates the seasonal atmospheric temperature, It is determined that power is not supplied to the LED module 300 when the temperature is equal to or lower than the temperature of the temperature sensor.

A temperature sensor (not shown) for measuring the internal temperature of the LED module 300 is installed in the LED module 300, and the temperature sensor transmits the measured temperature to the security processor 560. Depending on the brightness of the LED, the temperature inside the luminaire will change.

For example, assuming that the sensor temperature (internal temperature of the lamp) is 65 ° C at 100% brightness and 35 ° C at 50%, even though the brightness is increased from 50% to 100% It is determined that a part of the LED elements is not turned on.

The processor 560 controls the brightness of the corresponding smart security light 200 or the LED module 300 in various ways and reads the temperature sensor value to finally determine whether the defective information Can be determined. Here, the process of controlling, detecting, and comparing brightness and temperature values in various ways is judged experimentally until the final failure is judged.

In addition, the processor 560, such as security, may determine that the LED module 300 does not operate when the amount of power consumption reported from the power supply device 400 is less than a predetermined value.

The security processor 560 collects power consumption and escape information for each group and outputs statistics and reports the statistics to the upper layer operating server 40. [

FIG. 7 is a block diagram illustrating a power supply 400 according to an embodiment of the present invention shown in FIG.

Referring to FIG. 7, a power supply device 400 according to an embodiment of the present invention may include a power supply unit 410 and a power detection unit 420.

The power supply unit 410 may be a general SMPS (Switching Mode Power Supply) or a battery that supplies power by a switching operation. When the power supply unit 410 is the SMPS, the SMPS is a two-port SMPS that supplies 50V and 5V to the LED module 300 and the power conversion unit 550, respectively. The SMPS is a universal SMPS that simultaneously supports 50watt and 70watt with the time constant adjustment Can be used. To this end, a time constant switch for adjusting the time constant, that is, a rotary connector, may be mounted on the power supply device 400.

The time constant switch can adjust the current of 50V. In other words, there are two time constants (ie RC circuit) in the time constant switch. To set 50watt, set the rotary switch to 50W time constant. To set 70watt, set the rotary switch to 70W time constant .

The SMPS 410 includes an EMI filter and rectifier circuit, a PFC circuit, a power conversion circuit, a rectification filter circuit, a voltage detector, a current detector, a constant current control circuit, a constant voltage control circuit, Technology, so a detailed description is omitted.

The power detector 420 includes an input current detector 421, an input voltage detector 422, an arithmetic circuit 423, a data buffer 424, and a display circuit (not shown) to detect the power consumption of the smart security light 200 425).

The input current detector 421 and the input voltage detector 422 can detect the input current and the input voltage of the AC power input to the power supply unit 410. The input current and input voltage can be detected using an ADC (AC-DC Converter) circuit, which is a semiconductor IC that converts the analog signal to digital.

The computing circuit 423 can calculate the power consumption of the smart security light 200 using the detected input current and input voltage. For example, the arithmetic circuit 423 performs various signal processing such as eliminating the upper peak and the lower peak of the input current and the input voltage and then multiplying the multiplied result and using the intermediate value of the multiplied result to calculate the power consumption, i.e., can do.

The calculation circuit 423 can sense the heat generation temperature of the power supply device 400 or the LED module 300 and the output current and output voltage of the power supply device 400.

The data buffer 424 can read and store the detected amount of power consumption from the computing circuit 423 in real time. The computing circuit 423 detects the power consumption at intervals of, for example, one second, and the data buffer 424 can update the power consumption in units of one second.

The communication device 500 may take power consumption from the data buffer 424 when it is required to report the power consumption to the operating server 100, such as smart security.

The display circuit 425 can display the detected power consumption amount or the output current, the output voltage, and the temperature.

FIG. 8 is a schematic diagram of the software stack of the smart security light 200 shown in FIG.

8, the software stack of the smart security server 200 includes an operating system (RTOS) that manages overall software, a general device driver (Generic Device Driver), a device driver (Platform Device Driver) An abstract platform connection layer (Platform Abstration Layer) for connecting the object broadcasting middleware and the device driver, and an operation for extracting the control data by scanning the object radio frequency channel And stores the log data (for example, power consumption amount) and transmits the log data through the return channel to the operation server 100 (for example, the smart security server 200) And an application that plays a role of reporting to the user.

Here, Broadcasting Of Things (BoT) is a term defined in this specification and is a concept different from Internet of Things (IoT). In the case of the Internet (IoT), the object-to-be-broadcast (BOT) described in the present invention corresponds to a communication technology using a communication network of a radio frequency band, (E.g., a plurality of smart security lamps 200) at an infinite number of objects (e.g., an operating server 100, such as a broadcaster, e.g., smart security).

9 is a diagram for explaining an SRMS method of an operating system such as smart security according to an embodiment of the present invention.

In the Smart Relay Monitoring System (SRMS), one smart security (N + 100) transmits data to be uplinked to the fifth APCS 100 to other nearby smart security (N + 99) Smart security, etc. to the operational server, that is, the fifth APCS 100.

The bandwidth of the uplink data is as low as a few bps and the total area of the built-in smart security lamps is wide, so that the operation server 100, such as smart security, May be used if uplink communication is not possible.

In the case of FIG. 9, assume that the data size relayed by one smart security light is 1 KB including the ID of the smart security light. Assuming that there are 100 smart security lights, the last N smart security lights N are transmitted to the fifth APCS 100 ) May be (N + 100) bytes.

This SRMS scheme can be used when the downlink is easy, such as DTV or satellite, while the uplink is difficult. That is, the control signal for the fifth APCS 100 to control the smart security lights 200 should be transmitted to and controlled by the smart security lights 200 in real time, while the control signals for controlling the uplink data of the smart security lights 200 For example, the SRMS method may be used when the power consumption report data does not need to be collected in real time (for example, reporting once a day), such as the warehouse information.

In addition, the SRMS method can be advantageously used when receiving uplink data from a small number of installed smart security devices such as smart security, which are not managed by the operation server 100. For example, it is inefficient to construct an operating server 100 together with a smart security system for a smart security system, but it is necessary to detect and report the power consumption. In this case, the smart security system uses SRMS And can transmit its uplink data to another specified smart security light.

Smart security, etc. The operating server 100 compares the calculated total power consumption with the mapping table as shown in Table 1, and when the level of the total power consumption reaches one of the risk levels (one of W1 to W6) (S1600 (S1700). In this case, it is possible to transmit the illumination control signal to the security lamps of the group of the plurality of smart security lamps 200 at the risk level so as to adjust the illuminance downward.

In this manner, the smart security lamps 200 belonging to the group adjust the illuminance to the lower level set in the illumination control signal (S1800).

In addition, the operational server 100 such as smart security may report to the upper layer operating server, that is, the fourth APCS 40, that the total power consumption of its jurisdiction area is dangerous (S1900).

Meanwhile, according to the embodiment of the present invention, the brightness, that is, the illuminance of the LED module 300 is affected by the heat generated by the LED module 300. Therefore, in order to improve the illumination, the BOT communication device 500 and the power supply device 400 may be separated from the LED module 300 and disposed at a distance of about 7 meters or more. Therefore, in order to improve the illuminance to 50 watt or more, the length of the cable connecting the communication device 500 and the LED module 300 may be 7 meters or more.
