The gateway 12 manages the schedule data transmitted from the management server 11 and transmits a control message for operating the DALI ballast 14 according to the schedule data to the DALI ballast 14. For example, the gateway 12 according to the schedule data transmitted from the management server 11, to increase the illuminance of the bedroom according to the weather time, to cut off the power after a certain time after sunset, or to leave a certain time after leaving the user After this, the DALI ballast 14 can be controlled to cut off the power supply. The gateway 12 requires a real time clock (RTC) to manage such schedule data.

The gateway 12 refers to a control device that generates a control message for controlling the DALI ballast 14 based on the control information transmitted from the management server 11 and transmits the control message to the gateway adapter 13. 3 is a block diagram illustrating an embodiment of a gateway 12.

The communication unit 12-1 performs bidirectional communication between the management server 11 and the gateway adapter 13 through wired or wireless communication. The communication unit 12-1 receives control information for controlling the DALI ballast 14 from the management server 11 in communication with the management server 11, and receives the DALI ballast 14 from the DALI ballast 14 through the gateway adapter 13.

The gateway 12 may transmit a control message including the ballast address to the plurality of DALI ballasts through the gate adapter, thereby controlling each of the plurality of DALI ballasts.

The plurality of DALI ballasts may be divided into a plurality of ballast groups each including one or more DALI ballasts, and may be controlled for each group. For example, when there are a plurality of control spaces each provided with a plurality of lighting devices and a plurality of DALI ballasts for driving the same, the plurality of DALI ballasts installed in each control space are divided into one group, and thus the overall control space. Can be controlled group by group to produce a scene suitable for the purpose of. In this case, the gateway 12 may control the plurality of DALI ballasts by group by transmitting a control message including the group information and the ballast address through the gateway adapter 13.

The gateway adapter 13 refers to a control device that performs communication protocol conversion between the communication protocol used by the gateway 12 and the DALI communication protocol. The communication protocol used by the gateway 12 is different from the DALI communication protocols such as Ethernet, RS-232, and RS-485. Thus, when the gateway 12 and the DALI ballast 14 are directly connected, the user cannot control the DALI ballast 14 through the gateway 12. This problem can occur when the existing DALI communication-based lighting system is controlled by connecting to a wired network environment such as the Internet. That is, when the communication protocol using the DALI communication-based lighting system connects with different network environments, the gateway adapter 13 is necessary for communication protocol conversion.

4 is a block diagram illustrating an embodiment of a gateway adapter 13. As shown in FIG. 4, the gateway adapter 13 may include a communication unit 13-1 communicating with the gateway 12 and the DALI ballast 14, and a protocol conversion unit 13-2 performing communication protocol conversion.

The protocol conversion unit 13-2 converts the communication protocol into a conversion control message based on the DALI communication protocol using the control message received from the communication unit 13-1. The protocol conversion unit 13-2 transmits the conversion control message in which the communication protocol is converted to the communication unit 13-1. The communication unit 13-1 transmits the conversion control message to the DALI ballast 14 using DALI communication, so that the DALI ballast 14 is controlled according to the conversion control message. Since only the communication protocol is converted between the control message and the conversion control message for transmission and reception between components, the information included in each message is not changed and is the same.

In addition, the gateway adapter 13 may receive state information including the current illuminance, a failure state, and the like from the DALI ballast 14. The received state information is information generated based on the DALI communication protocol, and communication protocol conversion is also required to transmit it to the gateway 12. Accordingly, the gateway adapter 13 converts the received state information to the gateway 12 by converting the communication protocol based on the communication protocol used by the gateway 12.

The DALI ballast 14 refers to a control device for driving the lighting device using the conversion control message transmitted from the gateway adapter 13 through the DALI communication. 5 is a block diagram illustrating one embodiment of a DALI ballast 14. As shown in FIG. 5, the DALI ballast 14 may include an illumination driver 14-1, a power supply 14-2, and a DALI unit controller 14-3.

The lighting device may be, for example, a red, green and blue LED representing three primary colors of white LED and / or light. The lighting device may also include a lamp driven in a different manner from the LED, such as a halogen lamp or xenon lamp. The lighting driver 14-1 may perform driving operations such as on / off control, dimming control, and color control of the lighting apparatus. For example, if the lighting device is an LED, the dimming control may include sequential information about the DC drive voltage between 0 and 10 V, and the DC drive for each of the red, green and blue LEDs to control the color. It may also include information about the voltage.

The power supply unit 14-2 supplies power required for driving the lighting driver 14-1 according to the control signal of the DALI unit control unit 14-3. The power supply unit 14-2 may be a voltage converter using the AC power as it is, or may be a switching mode power supply (SMPS) for supplying power by converting the AC power to the DC power in a switching manner. In particular, the LED is driven at a lower DC drive voltage than other lamps, and is more likely to be damaged due to the DC drive voltage instability. Therefore, when the lighting apparatus including the LED is employed, the power supply unit 14-2 preferably includes an SMPS capable of supplying a constant DC driving voltage without being influenced by an external voltage change.

The DALI unit control unit 14-3 receives the conversion control message transmitted from the gateway adapter 13 and generates a control signal for controlling the power supply unit 14-2 and the lighting driver 14-1 therefrom. . For example, the control signal may include information for adjusting the magnitude of the DC driving voltage generated by the power supply unit 14-2 for illuminance control or dimming control. In addition, it may include information for turning on / off the driving signal of the lighting driver 14-1 in order to turn on / off the lighting device.

As shown in FIG. 6, the lighting control device according to an embodiment of the present invention includes a switch 15. The DALI ballast 14 can be controlled directly from the switch 15 without the gateway 12. On the other hand, when the switch 15 uses a communication protocol other than the DALI communication based protocol, the switch 15 cannot directly control the DALI ballast 14. Accordingly, even in this case, a switch adapter 16 is required between the switch 15 and the DALI ballast 14 to perform communication protocol conversion for smooth communication. The configuration of the switch adapter 16 is similar to that of the gateway adapter shown in FIG. That is, the switch adapter 16 may include a communication unit communicating with the switch 15 and the DALI ballast 14, and may include a protocol conversion unit converting the switch message into a conversion switch message based on the DALI communication protocol.

The switch 15 generates a switch message for controlling the DALI ballast 14 and transmits the generated switch message to the DALI ballast 14 by using the ballast address assigned to the DALI ballast 11. ). If a different communication protocol is used between the switch 15 and the DALI ballast 14, the switch 15 sends a switch message to the switch adapter 16, and the switch adapter 16 uses the switch message to DALI. The communication protocol-based conversion switch message is generated and transmitted to the DALI ballast 14 to control the DALI ballast 14.

On the other hand, when the conversion control message and the conversion switch message is transmitted to the DALI ballast 14 at the same time, the collision problem of which message is driven by the DALI ballast 14 may occur.

To resolve the conflict problem, switch messages and control messages can be selectively applied to the DALI ballast by the gateway. Specific embodiments thereof will be described below. Since the gateway 12 and the gateway adapter 13, the switch 15, and the switch adapter 16 are connected by direct communication, the gateway may be replaced by a gateway adapter and a switch by a switch adapter in the following detailed description. .

According to an embodiment of the present disclosure, the gateway 12 or the switch 15 may include a mechanism for detecting a message collision when the message is transmitted, and when the collision is detected through this mechanism, the transmission of the control message or the switch message is stopped. Then, after a predetermined waiting time elapses, the gateway 12 or the switch 15 attempts to retransmit the interrupted control message or switch message. If a collision is not detected by retrying the message, the DALI ballast 14 is controlled according to the message that attempted retransmission. In this case, the predetermined waiting time may be set according to a predefined priority for the gateway 12 or the switch 15. In addition, when the present invention includes a plurality of switches 15, the priority may be set independently for each switch. In this case, the higher the priority, the shorter the waiting time, and the lower the priority, the longer the waiting time may be set. Therefore, the higher the priority, the more frequent attempts to transmit the control message or the switch message, and the higher the possibility of controlling the DALI ballast 14 at an earlier time after the collision problem is solved.

According to another embodiment, the gateway 12 or switch 15 transmits the message transmission priority to each other before sending the control message or switch message to the DALI ballast 14. Then, when a collision problem occurs between the control message and the switch message, the gateway 12 or the switch 15 compares message transmission priorities with each other. As a result of the comparison of the message transmission priority, a control message or a switch message by a component having a high message transmission priority is transmitted to the DALI ballast 11, and a component having a low message transmission priority transmits a control message or a switch message. Stop. After stopping the transmission of the message, a component with a low message transmission priority may attempt to resend the message after a predetermined waiting time has elapsed. The message transmission priority may be stored in a memory provided in each of the gateway 12 or the switch 15. In addition, when the present invention includes a plurality of switches, the message transmission priority may be set for each switch, and the message transmission priority may be stored in a memory included in each switch.

FIG. 7 is a block diagram illustrating one embodiment of a combination of switch 15, switch adapter 16, and DALI ballast 14.

The switch 15 may be connected to one or more DALI ballasts 14 to directly control the DALI ballasts 14. In addition, the switch 15 may control each DALI ballast 14 using the ballast address assigned to each DALI ballast 14. When the switch 15 controls the DALI ballast 14 according to the ballast address, the ballast address to be controlled may be stored in a memory provided in the switch 15. In this case, the ballast address stored in the memory of each switch 15 to control the DALI ballast 14 may be set and managed by the management server 11. In addition, the user may freely change the ballast address stored in the switch 15 through the user interface 11-3 provided in the management server 11 and store it in each switch 15.

The remote controller 18 controls the driving of the DALI ballast 14 through wireless communication such as infrared communication, Bluetooth, wireless Internet, and wired communication environment. That is, the remote controller 18 can control the DALI ballast 14 without going through the management server 11. Therefore, in the lighting system integratedly managed by the management server 11, the user can independently control the lighting setting according to the user's purpose or taste at the place where the user is located by using the remote controller 18.

The remote control control signal by the remote controller 18 may be transmitted to at least one of the DALI unit controller 14-3, the gateway 12, the gateway adapter 13, the switch 15, and the switch adapter 16. According to an embodiment of the present invention, at least one of the gateway 12, the gateway adapter 13, the switch 15, the switch adapter 16, and the DALI unit controller 14-3 may be used to receive a remote control control signal. The receiver may be included. Since the gateway 12 and the gateway adapter 13, the switch 15, and the switch adapter 16 are connected by direct communication, the gateway may be replaced by a gateway adapter and a switch by a switch adapter in the following detailed description. .

As shown in FIG. 8, when the remote control control signal is transmitted to the DALI unit control unit 14-3 of the DALI ballast 14, according to an embodiment, the DALI unit control unit 14-3 is connected to the gateway 12. The control signal is generated according to the remote control signal, not the control message, thereby controlling the lighting driver 14-1 and the power supply unit 14-2.

As shown in FIG. 8, when the remote control control signal is transmitted to the gateway 12, the gateway 12 generates a control message using the transmitted remote control control signal. The gateway 12 transmits the generated control message to the DALI ballast 14 through the gateway adapter 13 to control the driving of the DALI ballast 14. In this case, the remote controller control signal transmitted to the gateway 12 may include a ballast address assigned to the DALI ballast 14 to be controlled and a control operation of the corresponding DALI ballast 14. That is, the remote controller 18 transmits a remote controller control signal including a ballast address and a control operation to the gateway 12, and the gateway 12 generates and transmits a control message using the remote controller control signal to transmit the corresponding DALI ballast 14. ).

According to another embodiment, the gateway 12 determines the priority between the control information transmitted from the management server 11 and the remote control control signal, and generates and transmits a control message according to the determined priority to thereby correspond to the corresponding DALI ballast 14. ) Can also be controlled. In this case, the gateway 12 may determine the priority between the control information and the remote control control signal with reference to a predetermined setting value stored in the memory included in the gateway 12.

As shown in FIG. 8, when the remote controller control signal is transmitted to the gateway adapter 13, the gateway adapter 13 converts the received remote controller control signal into a conversion control message to convert the DALI ballast 14. The lighting device can be driven by transmitting to.

As shown in FIG. 8, when the remote control control signal is transmitted to the switch 15, the remote control control signal is driven in the same manner as the operation of controlling the DALI ballast 14 by driving the switch 15. In this case, the remote controller control signal transmitted to the switch 15 may include a ballast address assigned to the DALI ballast 14 to be controlled and a control operation of the corresponding DALI ballast 14. The switch 15 receiving the remote control signal generates a switch message based on the ballast address and the control operation included in the remote control signal, and transmits the switch message to the DALI ballast through the switch adapter 16 to control the corresponding DALI ballast. In addition, the ballast address of the DALI ballast to be driven may be included in the remote control control signal, but may otherwise control the DALI ballast previously assigned to the switch 15.

Meanwhile, as the remote controller control signal is transmitted to the switch 15, the switch message generated by using the remote controller control signal and the control message by the gateway 12 are simultaneously transmitted through the switch adapter 16 and the gateway adapter 13, respectively. When transmitted to the DALI ballast 14, a collision problem may arise with which message the DALI ballast 14 will be driven.

To resolve the conflict problem, switch messages and control messages can be selectively applied to the DALI ballast by the gateway. Specific embodiments thereof will be described below.

Then, after a predetermined waiting time elapses, the gateway 12 or the switch 15 attempts to retransmit the interrupted control message or switch message. If a collision is not detected by retrying the message, the DALI ballast 14 is controlled according to the message that attempted retransmission. In this case, the predetermined waiting time may be set according to a predefined priority for the gateway 12 or the switch 15. In addition, when the present invention includes a plurality of switches 15, the priority may be set independently for each switch. In this case, the higher the priority, the shorter the waiting time, and the lower the priority, the longer the waiting time may be set. Therefore, the higher the priority, the more frequent attempts to transmit the control message or the switch message, and the higher the possibility of controlling the DALI ballast 14 at an earlier time after the collision problem is solved.

Since the gateway 12 and the gateway adapter 13, the switch 15, and the switch adapter 16 are connected by direct communication, the gateway may be replaced by a gateway adapter and a switch by a switch adapter in the following detailed description. .

As shown in FIG. 8, when a detection signal is transmitted to the gateway 12, the gateway 12 composes a control message using the received detection signal and transmits it to the DALI ballast 14 through the gateway adapter 13. DALI ballast 14 can be controlled by transmitting For example, the sensor unit detects this when the user enters a place where the lighting is off, generates a detection signal, and transmits the generated detection signal to the gateway 12. Upon receiving the detection signal, the gateway 12 generates a control message for turning on the lighting, and transmits the generated control message to the DALI ballast 14 through the gateway adapter 13 to turn on the lighting. ). Alternatively, in a place where uniform illuminance is to be maintained, the sensor unit detects a shade area generated by a part of the illumination covered by the user, generates a detection signal, and transmits the detection signal to the gateway 12. Upon receiving the detection signal, the gateway 12 generates a control message to maintain illumination by directly illuminating the corresponding shade area using another light, and transmits it to the DALI ballast 14 through the gateway adapter 13 to transmit the DALI ballast. By controlling (14), the illuminance of the place can be kept uniform.

As shown in FIG. 8, when a detection signal is transmitted to the gateway adapter 13, the gateway adapter 13 converts the received detection signal into a conversion control message and transmits the received detection signal to the DALI ballast 14. Thus, the lighting device can be driven.

As shown in FIG. 8, when a detection signal is transmitted to the switch 15, the switch 15 generates a switch message using the received detection signal, and generates the switch message through the switch adapter 16. The DALI ballast 14 can be controlled by sending it to the DALI ballast 14.

As shown in FIG. 8, when a detection signal is transmitted to the switch adapter 16, the switch adapter 16 converts the received detection signal into a conversion switch message and transmits the received detection signal to the DALI ballast 14. Thus, the lighting device can be driven.

As shown in FIG. 8, when the detection signal is transmitted to the DALI unit control unit 14-3, the DALI unit control unit 14-3 generates a control signal using the received detection signal, and generates the generated control signal. The power supply unit 14-2 and the lighting driver 14-1 may be controlled by using the control unit.

9 to 11 are diagrams illustrating each step of the lighting control method according to embodiments of the present invention. Hereinafter, the lighting control method according to the present invention will be described in detail with reference to FIGS. 9 to 11.

As shown in FIG. 9, control information is generated based on the information input from the user in step S91, and the generated control information is transmitted to the gateway by wire or wireless communication. Control information is generated by the management server. The control information may be generated based on information input through a user interface such as a keyboard input device provided in the management server. In addition, the control information may be generated based on information remotely input from an external client connected to the management server through a wired or wireless network. The external client may include, for example, a portable wireless communication terminal such as a mobile phone, a smartphone, or the like.

The control information may be generated using state information including the current illuminance around the DALI ballast, whether there is a failure or the like. That is, when a failure occurs in some lighting devices, the management server uses the state information including the information to generate control information to cut off the power of the failed lighting device and transmit the control information to the gateway, thereby providing power to the corresponding DALI ballast. Can be turned off. Status information is sent from the DALI ballast to the management server via the gateway adapter and gateway. In addition to the status information, the control information may include on / off control, dimming control, and color control information of the lighting apparatus.

A plurality of gateways may be connected to the management server, and a plurality of DALI ballasts may be connected to one gateway. The control information may include a gateway address, a ballast address, and the like. Accordingly, the management server may control only the gateway to be driven using the gateway address included in the control information, and thus the gateway to be driven may control only the corresponding DALI ballast using the ballast address.

The generated control information is transmitted to the gateway through wired and wireless communication so that the gateway is controlled by the management server. Short-range or long-distance communication in the form of RS-232, RS-485, USB, Ethernet, or RF (Radio Frequency) may be used as wired or wireless communication.

In step S92, a control message is generated based on the control information, and the generated control message is transmitted to the gateway adapter. The control message is generated by the gateway based on the control information received from the management server. The generated control message is used to control the DALI ballast.

The control message may be generated including information on driving operations such as ballast address, on / off control, dimming control, and color control. In addition, the control message may be generated including the state information received from the DALI ballast through the gateway adapter.

The plurality of DALI ballasts may be divided into a plurality of ballast groups each including one or more DALI ballasts, and may be controlled for each group. Accordingly, the gateway may control the plurality of DALI ballasts by group by transmitting a control message including the group information and the ballast address through the gateway adapter. In general, up to 64 DALI ballasts can be controlled for one gateway and gateway adapter, and can be controlled divided into up to 16 groups.

In step S93, the control message is converted into a conversion control message based on the DALI communication protocol, and the conversion control message is transmitted to the DALI ballast. The communication protocol used by the gateway differs from the DALI communication protocols such as Ethernet, RS-232, and RS-485. Therefore, when directly connecting the gateway and the DALI ballast, the user cannot control the DALI ballast through the gateway. This problem can occur when the existing DALI communication-based lighting system is controlled by connecting to a wired network environment such as the Internet. That is, when a communication protocol using a lighting system based on DALI communication is connected with a different network environment, a gateway adapter is required for communication protocol conversion.

The gateway adapter receives a control message from the gateway and converts the communication protocol into a conversion control message based on the DALI communication protocol using the received control message. The gateway adapter sends a conversion control message to the DALI ballast so that the DALI ballast is controlled according to the conversion control message. Since only the communication protocol is converted between the control message and the conversion control message for transmission and reception between components, the information included in each message is not changed and is the same.

In addition, the gateway adapter may receive status information, including current illuminance, fault conditions, and the like from the DALI ballast. The received state information is generated based on the DALI communication protocol, and communication protocol conversion is also required to transmit this to the gateway. Therefore, the gateway adapter converts the received state information based on the communication protocol used by the gateway and transmits the communication protocol to the gateway.

In operation S94, the lighting apparatus is driven by the DALI ballast based on the conversion control message. In order to drive the DALI ballast lighting device, a control signal may be generated based on the conversion control message, and the lighting device may be driven using the control signal. The generated control signal may include information about driving operations such as on / off control, dimming control, and color control of the lighting apparatus. For example, when the lighting device is an LED, the dimming control may include sequential information about a DC driving voltage between 0 and 10V. Or, it may include information on the DC driving voltage for each of the red, green and blue LED to control the color.

The lighting control method according to an embodiment of the present invention may further include generating a switch message and transmitting the generated switch message to a DALI ballast to control the DALI ballast. Switch messages are converted to conversion switch messages via a switch adapter and sent to the DALI ballast to drive the lighting.

The lighting control method according to an embodiment of the present invention includes generating a switch message, converting the communication message into a conversion message based on the DALI communication protocol, and transmitting the conversion switch message to the DALI ballast. Since the gateway and the gateway adapter and the switch and the switch adapter are directly connected, in the following description, the gateway (or control message) is the gateway adapter (or control conversion message), and the switch (or switch message) is the switch adapter ( Or a conversion switch message).

Referring to FIG. 10, the gateway generates a control message based on the received control information (S91), and the gateway adapter generates a conversion control message based on the received control message (S92), whereby a collision is detected through a collision detection mechanism. If not detected (S101), the generated message is finally transmitted to the DALI ballast (S93). When the transmission is normally completed, the DALI ballast drives the lighting device according to the control message (S102).

The gateway or switch may include a mechanism to detect message collisions in the transmission of the message, which stops sending control messages or switch messages when a collision is detected. Thereafter, after the predetermined waiting time has elapsed, the gateway or the switch attempts to retransmit the interrupted control message or the switch message (S103). If a collision is not detected by retrying the message, the DALI ballast is controlled according to the message that attempted retransmission. In this case, the predetermined waiting time may be set according to a predefined priority for the gateway or the switch. In addition, when the present invention includes a plurality of switches, the priority may be set independently for each switch. In this case, the higher the priority, the shorter the waiting time, and the lower the priority, the longer the waiting time may be set. Therefore, the higher the priority, the more frequent attempts to transmit control messages or switch messages, and the greater the likelihood of controlling the DALI ballast at an earlier time after the collision problem is resolved.

Referring to FIG. 11, the management server generates control information and transmits the generated control information to the gateway (S91). The gateway or switch sends message transmission priority to each other through the gateway adapter and the switch adapter before sending the control message or switch message to the DALI ballast. The gateway generates a control message based on the received control information, and transmits the generated control message to the gateway adapter (S92). The gateway adapter generates a conversion control message based on the received control message, and determines whether a collision occurs between the control message and the switch message when transmitting the generated message to the DALI ballast (S93) (S111). If no collision occurs as a result of the determination, the conversion control message is normally transmitted to the DALI ballast and the lighting device is driven according to the conversion control message (S112).

If a collision occurs, the gateway or the switch compares the message transmission priority of each other (S113). As a result of the comparison of the message transmission priority, the control message or the switch message by the component having the high message transmission priority is transmitted to the DALI ballast (S114). The component having a low message transmission priority may stop transmitting the control message or the switch message and attempt to retransmit the message after a predetermined waiting time has elapsed (S115). The message transmission priority may be stored in a memory provided in each of the gateway or the switch. In addition, when the present invention includes a plurality of switches, the message transmission priority may be set for each switch, and the message transmission priority may be stored in a memory included in each switch.

When the detection signal is transmitted to the gateway, the gateway may control the DALI ballast by creating a control message using the received detection signal, converting the communication protocol through the gateway adapter, and then transmitting the control message to the DALI ballast.

When the detection signal is transmitted to the switch, the switch generates a switch message using the received detection signal, sends the generated switch message directly to the DALI ballast through DALI communication, or converts the communication protocol through the switch adapter. You can control the DALI ballast by sending it to a DALI ballast.

When the detection signal is transmitted to the DALI unit control unit, the DALI unit control unit may generate a control signal using the received detection signal, and drive the lighting apparatus by controlling the power supply unit and the lighting driver using the generated control signal. .

In this way, the DALI ballast can be controlled by using the remote control without going through the management server.

When the remote control control signal is transmitted to the DALI unit control unit, according to an embodiment, the DALI unit control unit may generate a control signal according to the remote control signal instead of the control message by the gateway to control the lighting driver and the power supply unit.

When the remote control control signal is transmitted to the gateway, according to an embodiment, the gateway generates a control message by using the transmitted remote control signal, converts the generated control message through a gateway adapter, and then transmits the generated control message to the DALI ballast. The driving of the DALI ballast can be controlled. In this case, the remote control control signal transmitted to the gateway may include a ballast address assigned to the DALI ballast to be controlled and a control operation of the corresponding DALI ballast.

In this case, the remote control control signal transmitted to the switch may include a ballast address assigned to the DALI ballast to be controlled and a control operation of the corresponding DALI ballast.
