Description

TECHNICAL FIELD [0001] The present invention relates to a network management system and a method thereof,

The present invention relates to a network management system and method thereof, and more particularly, to an LCU (light control unit) provided in an illumination lamp, in which a DCU (Data Control Unit) The present invention relates to a network management system and a method for controlling the DCUs by collectively controlling the DCUs by setting the servers as groups and automatically connecting the LCUs to the DCUs and servers.

The present invention can control LED dimming and external power through collective control of LCU groups or control of LCU grouped automatically by scheduling according to the predetermined time according to the server, and when the operator recognizes a special situation , It is possible to control LED dimming and external power through collective control of manually grouped LCU or exclusive control of LCU. The present invention also relates to a network management system and a method thereof, which can monitor general information and control results of an LCU from a server system.

The present invention relates to a network management system and its method such as a lighting system, in which an LCU sets a main control DCU and a sub control DCU and is controlled by communication with a sub control DCU according to a communication error with the main control DCU.

In general, a light fixture means an outdoor fixture for the purpose of safety or security of lighting or traffic of the surrounding scenery or the street.

The lighting of the illumination lamp is activated by time, ambient brightness and control of the control center.

The lighting system includes a lamp mounted on the ground, a lamp for lighting installed on the top of the lamp, a power line connected to the bottom of the lamp and embedded in the ground, a control unit connected to the power line for controlling the lamp, .

Here, the luminaire of the lighting lamp may be composed of an LED.

LED is an abbreviation of light emitting diode. It is a semiconductor device that emits light by flowing current to a compound such as gallium arsenide. When a current passes through a conductive material with an electrode on the bottom of the LED, It is a structure in which charge particles couple at the center of the electrode and emit photons of light, and are emitted in various colors depending on the characteristics of the material. In this case, the luminescent color of the luminaire used as the luminaire of the luminaire is mainly an LED which emits white light.

Since the LED lamps do not use filaments, they are less efficient than fluorescent lamps, incandescent lamps, etc., and have low efficiency, good power consumption, and long life.

However, LED lamps generate heat while converting electrical energy into light energy, which can generate a large amount of heat depending on the conditions of use. Heat generation in the LED luminaire shortens the lifetime of the LED luminaire and lowers the electric efficiency.

In order to solve the heat generation of the LED lamp, there is a technology for controlling the heat generation of the lamp by controlling the input power of the LED lamp, and in Japanese Patent Application Laid-Open No. 10-2012-0061256, LED dimming A lighting apparatus is described.

That is, by controlling the current input to the LED lamp, it is possible to minimize the heat generation amount, thereby reducing the lifetime and power consumption of the lamp. However, in order to individually control each LED luminaire, the number of LED luminaires is relatively large, so that a large amount of data must be transmitted. Thus, it is practically difficult to control dimming of each lighting lamp.

On the other hand, a remote control system and method such as illumination lamp / security is disclosed in Patent Registration No. 10-0911261 as one of technologies for collectively controlling a plurality of illumination lamps by groups or by units or regions.

However, even in the case of an LED luminaire, the amount of heat generated increases depending on the structure of the luminaire and the installation environment, and a failure such as shortening the lifetime of the LED luminaire may occur as the amount of heat generated increases.

Therefore, it is required to develop a network management system and a method for controlling the illuminance of a lamp or the like by collective control of a group of illuminated lamps, .

The present invention also relates to a system and method for controlling a dimmable network management system capable of collectively controlling dimming control of an LED connected to an LCU through a single control of the LCU.

It is still another object of the present invention to provide a network management system of a lighting system and the like that can control a main control DCU and a sub control DCU by communication with a sub control DCU in accordance with a communication error with the main control DCU .

According to an aspect of the present invention, there is provided a network management system and method for a lighting apparatus including an LCU installed in an illumination lamp and controlling an LED; DCUs that control LCUs in groups; And a server for controlling the DCU, wherein the server stores and manages the main control DCU and the sub control DCU corresponding to each of the LCUs, and controls the LCU through the sub control DCU according to whether the main control DCU is abnormal As a technical feature.

Also, the LCU automatically stores the main DCU and the sub control DCU by automatically selecting the DCU by activation, and when an error occurs in the communication with the main control DCU, the LCU transmits a communication error to the server through the sub control DCU A network management system and a method thereof.

In the present invention, a plurality of LCUs are set as a group, the LCUs are collectively controlled, and a plurality of DCUs are set as a group so that the DCUs are collectively controlled, and the LCU, the DCU, Or zone-by-zone monitoring control.

Therefore, the present invention has the effect of collectively controlling the dimming control of the LED connected to the LCU.

The DCU 200 and the server 300 have security on the Internet by communicating control and monitoring information through an SSL-based TCP / IP communication by a wired / wireless network.

TCP / IP is a network transport protocol, which allows data to be transmitted between devices using different operating systems, and is used as a standard protocol for information transmission on the Internet. TCP is a protocol for dividing and packing transmission data by a certain unit, and IP is a protocol for directly exchanging data.

In addition, SSL (Secure Sockets Layer) is an industry standard protocol for securely exchanging data between a world wide web browser and a web server. SSL can be applied to other TCP / IP applications such as file transfer protocols as well as web products , And an authentication encryption function.

As described above, the DCU 200 and the server 300 can communicate with each other via the general Internet, and it is natural that internal network communication is possible when the internal network is configured.

And may have a place for temporarily storing the control data and the monitoring data of the server 300. [

Therefore, monitoring data can be stored and controlled by using the stored data when a network problem occurs.

Also, the server 300 is connected to an operator terminal installed with monitoring software for the operator through the Internet, and can monitor or control related information of the LCU 100 and the DCU 200.

In addition, the server 300 stores and manages the DCU and the sub-control DCU in the topic corresponding to each of the LCUs 100, and controls the LCU through the sub-control DCU according to whether the main control DCU is abnormal. At this time, the server 300 may change the main control DCU and the sub control DCU according to other design conditions by the operation of the operator.

That is, each LCU 100 and the DCU 200 to be stored and managed are configured so that they can be changed by selection, and the DCU 200 is selectively grouped and controlled.

At this time, the server 300 may be integrated into the server group together with the web server and the database, or may be installed in the same place or the same PC.

Accordingly, a plurality of administrators can be connected to the server group and control the lighting system through the Internet. At this time, the operators may be given different privileges according to their logins.

For example, in the case of a super-operator, the LCU 100 can regroup a group of DCUs 200 and is authorized to control the scheduling of power output, It is possible to assign different privileges to different logins, such as having a light-off privilege.

The LCU 100, the DCU 100, and the server 300, which are the main components of the network management system of the lighting system, which are connected by wire / wireless communication and are capable of collectively controlling the illumination lamps, Explain.

FIG. 2 is a diagram schematically illustrating an internal configuration of an LCU in a network management system for a lighting system according to the present invention, and FIG. 3 is a block diagram showing the inside of an LCU in a network management system for a lighting system according to the present invention.

The external power supply unit 400 and the SMPS 500 are connected to the LCU 100 under the control of the LCU 100 as shown in FIG. .

The external power supply unit 400 is a device that allows the use of an illumination lamp provided with the LCU 100 as an AC power supply.

At this time, the external power supply unit 400 may be used to supply power to the outside under the control of the server 300, and the server 300 may monitor the power supplied to the outside. In addition, the external power supply unit 400 may supply power to the external power supply unit 400 only for a predetermined time period controlled by the server 300. In this case,

It is possible to supply electric power to a device or apparatus requiring outdoor AC power such as a billboard, a traffic light, a christmas tree, and the like and charge the supplied electric power through the external power supply unit 400 as described above.

At this time, charging for power can be performed by detecting power consumption supplied to an external device (refer to FIG. 2) to which power is supplied through the external power supply unit 400. [

The SMPS 500 supplies operating power to the LED 600 of the illumination lamp and receives the output power of the illumination lamp to apply the operating power to the LED 600.

A general SMPS 500 is an abbreviation for a switching mode power supply. The SMPS 500 converts a DC input voltage into a rectangular-wave voltage and obtains a DC output voltage controlled through a filter. To control the flow of electric power. In addition, it is a stabilized power supply device which is more efficient and durable than conventional power supply devices, and is advantageous in size and weight reduction.

The SMPS 500 according to the present invention is configured to dimming control of the illuminance of the LED 600 connected to the SMPS 500 in addition to the above functions and controls the output current of the SMPS 500, Can be controlled.

Next, the configuration of the LCU 100 will be described with reference to FIG.

The LCU 100 is installed in an illumination lamp and can control the external power supply unit 400 and the SMPS 500 based on a control signal and a detection signal. The LCU 100 includes a first communication module 110, an ID storage module 120, A control module 130, an SMPS control module 140, a GPS receiving module 150, a scheduling module 160, and a detection module 170.

The first communication module 110 is for communicating with the DCU 200, and may be configured to transmit and receive control signals and operating information and communicate wirelessly.

The ID storage module 120 stores the ID of the LCU 100, the ID of the main control DCU, and the ID of the sub control DCU. In this case, the ID (Identity) may be a unique number or a device number that can distinguish a device when applied to a device such as an LCU and a DCU, and may be a number that can be divided into groups when applied to a group , The device (LCU, DCU) and the group of devices.

Also, the same DCU ID may be stored in the ID storage module 120, which means that the LCUs 100 controlled by the same DCU 200 are set as one group.

At least one DCU is stored in the ID storage module 120 of the LCU 100. That is, the DCU controlling the corresponding LCU is stored and managed so as to belong to at least one DCU, which will be described with reference to FIG. 3A.

FIG. 3A is a diagram illustrating an embodiment in which LCUs are set in groups according to IDs set in a network management system of a lighting apparatus or the like according to the present invention.

3A, LCU 1 and LCU 2 set DCU 1 as a main control DCU, DCU 2 as a sub control DCU, LCU 3 and LCU 4 set DCU 2 as a main control DCU, DCU 1 is set as the sub-control DCU.

At this time, LCU 1, LCU 2, LCU 3, and LCU 4 are grouped into a group, and each receives control of the set DCU.

The dimming control module 130 performs dimming control on the LED 600 of the lighting unit in which the LCU 100 is installed.

The dimming control is performed based on illumination information of the scheduling module 160 and the detection module 170 or temperature detection of the SMPS 500 controlled by the server 300 according to a predetermined cycle (day, month, year, etc.) do.

At this time, the dimming control module 130 sets the current control value according to the current control value received from the server 300, the illuminance information of the detection module 170, and the temperature value of the SMPS 500 and sends the current control value to the SMPS 500, And when the control of the power supply of the power supply unit 500 is required, the control signal is transmitted through the SMPS control module 140.

The GPS receiving module 150 receives the position information of the illumination lamp in which the LCU 100 is installed, and the position information is longitude and latitude information.

The scheduling module 160 manages periodic schedule management information of the dimming control period controlled by the server 300. For example, the schedule for controlling the dimming of the LED 600 can be set differently according to the predetermined week, month, and year.

This is because the temperature of the SMPS 500 that applies power to the LED 600 can be influenced by temperature depending on the surrounding environment or the weather and the sunrise and sunset times vary with the period, Dimming control.

It is sufficient that the schedule management information for each cycle of the scheduling module 160 can be divided not only by the week, month, and year mentioned above, but also by periods (for example, time, date, etc.).

The detection module 170 detects power consumption, power factor, voltage, current, network connection error, illuminance information, and temperature of the SMPS 500 connected to the LCU 100.

The power consumption, the power factor, the voltage, the current, and the illuminance of the illumination lamp in which the LCU 100 is installed through the detection module 170 can be detected in real time using the time information of the GPS.

In addition, it is possible to detect a network connection error through the detection module 170 and provide a basis for allowing the LCU 100 and the server 300 to wirelessly communicate with each other through the DCU 200. That is, the detection module 170 detects a network connection error between the LCU 100 and the main control DCU, and can communicate with the sub control DCU to be controlled from the sub control DCU.

At this time, the LCU 100 automatically manages the main control DCU and the sub control DCU, selects the DCU 200 to which the LCU 100 is connected based on the communication error transmitted from the LCU 100, And transmits the detected communication error to the server 300 through the secondary control DCU.

This may be achieved by setting a sub control DCU through an operator terminal connected to the server 300 based on a communication error transmitted from the LCU 100 or by setting a sub control DCU based on a communication error transmitted from the LCU 100, DCU can also be set.

In addition, according to other design conditions, when a network connection error occurs, a light sensor can be controlled by forming a photo sensor (not shown) in the LCU 100.

In addition, dimming control can be performed by adjusting the illuminance of the LED 600 through the temperature monitoring of the SMPS 500.

A DCU 200 for collectively controlling these LCUs 100 in a group or individually controlling the LCU 100 based on a control signal of the server 300 will be described.

FIG. 4 is a block diagram schematically illustrating a configuration of a DCU in a network management system of a lighting system according to the present invention. The DCU 200 includes a 2-1 communication module 210, a 1-1 communication module 220, an ID A storage module 230, an LCU control module 240 and a group setting module 250. [

The 2-1 communication module 210 transmits the operation information of the LCU 100 to the server 300 and receives the control signal from the server 300 to communicate with the server 300 through the TCP / IP network .

The 1-1 communication module 220 is for communicating with the LCU 100 and transmits control signals to the LCU 100 and receives the operation information of the LCU 100. The 1-1 communication module 220 performs wireless communication using RF communication .

At this time, the operation information of the LCU 100 includes communication error, power factor, power consumption, current and voltage, temperature of the SMPS 500, and external power supply information.

The ID storage module 230 sets and manages the IDs of the LCUs to be controlled by the DCU 200 and the IDs of the LCUs to be controlled by the DCU 200 in a group.

The LCU control module 240 collectively controls the LCU ID group or the LCU ID group to be controlled by the DCU based on the control signal received from the server 300, Control.

The group setting module 250 sets and manages the LCU IDs, which are stored in the ID storing module 230, by separating the LCU IDs to be controlled by the DCU 200 and the LCU IDs to be controlled by the DCU 200, Are grouped on the basis of. This will be described with reference to FIG. 4A.

FIG. 4A is a diagram illustrating an embodiment in which DCUs are organized into groups according to an established ID in a network management system for a lighting system according to the present invention.

4A, DCU 1 sets LCU 1, LCU 2, and LCU 3 to the main control LCU, and sets LCU 4, LCU 5, and LCU 6 as sub control LCUs

Also, DCU 2 sets LCU 4, LCU 5, and LCU 6 as main control LCUs, and LCU 1, LCU 2, and LCU 3 are set as sub control LCUs.

Thus, LCU 1, LCU 2, and LCU 3 are set as the main language group in DCU 1, and LCU 4, LCU 5, and LCU 6 are set as the main language group in DCU 2.

In such a configuration, when a failure occurs in one DCU or an error occurs in the communication, it is configured to be controlled through a DCU registered as a sub-control.

For example, when a failure occurs in the DCU 1, the LCUs 1 to 3 are controlled through the DCU 2 set as the sub-control DCU and communicate with the server 300. [

Therefore, since the luminaire can be controlled through other DCU in case of communication error, it has the effect of extending the control range according to the communication error of the device.

5, the server 300 includes a second communication module 310, an ID storage module 320, a second communication module 320, a second communication module 310, An LCU control module 330, a DCU control module 340, a group setting module 350, and an LCU position information display module 360.

The second communication module 310 wirelessly communicates control signals and operation information with the DCU 200.

The ID storage module 320 sets and manages the ID of the DCU 200, the ID of the LCU to be controlled by the DCU 200, and the LCU ID to be controlled as a group.

The LCU control module 330 controls the LCU. A dimming control unit for controlling the illumination of the illumination lamp according to a general function of the LCU 100 and for controlling dimming of the illumination LED 600 and an external power output control unit for controlling application of external power through the external power output control unit, .

The DCU control module 340 can collectively control the DCU 200 or individually control the DCU 200. That is, the server 300 is configured to individually control the DCU 200 by organizing the DCU 200 into groups or canceling the selection.

For example, when the server 300 divides the DCU 200 into a plurality of groups and controls the DCU 200 divided into groups, the LCUs 100 organized in the DCUs 200 are collectively controlled, The LCUs 100 are collectively controlled when all the DCUs 200 are collectively controlled without dividing the DCUs 200 into groups. In addition, when the server 300 separately controls one DCU 200 without dividing the DCU 200 into groups, the server 300 is controlled to individually control the LCUs 100 organized in one DCU 200.

The group setting module 350 separately manages the IDs of the LCUs to be controlled by the DCU 200 and the IDs of the LCUs to be controlled by the DCU 200 stored in the ID storage module 320. At this time, The LCU IDs are grouped through the control unit 250.

For example, it is possible to distinguish the LCU 100 organized in the DCU 200 according to the ID stored in the ID storage module 320, and to identify the DCU 200 set by the LCU 100 as the sub- It is.

It is also possible to set the group of the DCU 200 for collective control of the DCU 200. That is, the collective control of the DCU 200 may be performed to collectively control the entire DCU 200 connected to the server 300, or to collectively control the group of DCUs 200 organized in the group.

The LCU location information display module 360 receives the location information received from the satellite by the GPS receiving module 160 of the LCU 100 and displays the location information of the LCU 100 in a geographic information system (GIS) As shown in Fig. At this time, the information displayed on the map may be configured to display not only the position of the LCU but also the main word DCU and sub-control DCU that control the corresponding LCU. Or may be configured to display, as a line, the main control DCU and sub-control DCU that control the LCU as shown in FIG.

With this configuration, since the LCU is displayed on the map and the DCU communicating with the LCU can be displayed, it is possible to easily confirm the arrangement and the fault position of the entire lighting, thus facilitating maintenance and repair.

As described above, the present invention includes the LCU 100, the DCU 200, and the server 300, and is configured to be easily controlled in a batch so that the control management of the illumination lamps distributed in a plurality of areas can be efficiently performed .

That is, since the LCU 100 can be controlled collectively, the dimming control of the illumination lamp can be also controlled in a batch.

The network management system such as a lighting system having such a configuration can be configured such that the LCU 100 can be automatically registered in the server 300. [ The installation time can be shortened by automatically registering and managing the DCU 200 and the server 300 by simply installing the illumination light. This process will be described with reference to FIG. 6, in which the LCU 100 automatically registers with the server 300 to be connected and activated.

FIG. 6 is a flowchart illustrating a method of managing a network of a lighting apparatus according to the present invention. The LCU wireless communication connection step S10, the LCU-server connection step S20, and the LCU activation step S30 are included.

(1) LCU wireless communication connection step (S10)

The LCU wireless communication connection step (S10) is a step in which the LCU (100) is automatically connected to the server (300) through wireless communication to form a network, and comprises the following steps.

a) a seek message transmission step in which the LCU 100 searches for the DCU 200 by wireless communication

- When a new light is installed and powered on, the LCU 100 randomly sends a Seek message.

b) wirelessly transmitting the seek message received by the DCU 200 to the LCU 100

Here, the LCU 100 recognizes the DCU 200 that transmitted the first arrived seek message 1 as the subject DCU, and recognizes the DCU 200 that transmitted the seek message 2 arriving later as the sub-control DCU.

The DCU 200 closest to the LCU 100 first receives the seek message and transmits the seek message to the LCU 100 because the wireless communication is performed using the mesh network. That is, the main control DCU and the sub control DCU are selected according to the order of the response signal of the DCU 200 corresponding to the seek message transmitted by the LCU 100 or the strength of the response signal.

Therefore, the sub-control DCUs stored in the respective LCUs 100 may be different even if the LCUs 100 are arranged in the same group and set the same subject DCU.

c) the LCU 100 wirelessly transmits a Link Done Request message to the DCU 200

Here, the DCU 200 to which the LCU 100 transmits the message may be the main DCU.

This is because, when communicating via the secondary control DCU, an error is detected in the network communication with the main control DCU, and in the normal case, it is via the main control DCU.

At this time, since the LCU 100 transmits a communication error with the main control DCU to the always-on server 300 via the sub-control DCU, it is possible to detect a communication error of the main control DCU.

d) The DCU 200 wirelessly transmits a Link Done response message to the LCU 100

- The DCU (200) receiving the Link Done Request message transmits a Link Done response message to the LCU (100).

At this time, the DCU 200 may temporarily store the LCU 100 information.

e) the DCU 200 wirelessly transmits the LCU Installation Message to the server 300

The DCU 200 transmits an LCU Installation Request message to the server 300.

Here, the LCU Installation Request message includes information of the LCU 100 temporarily stored in the DCU 200, and the information of the LCU 100 is stored in the server 300.

f) The server 300 wirelessly transmits an LCU Installation Response message to the DCU 200
