Fig. 4 is a view for explaining the address setting and the control relationship in the illuminator.

Referring to FIG. 4, an address setting unit 410, a program switch 420 and a plurality of illuminators 431 to 43N (N is a positive integer) can be used to set addresses in the illuminator.

The address setting unit 410 sets an address to each of the lighting devices 431 to 43N and the program switch 420. [ To this end, the address setting unit 410 includes control means such as, for example, a Commissioning Tool for address setting or other mobile devices. Here, the installation tool may be, for example, hardware or software including a program for address setting.

The address setting unit 410 may also be, for example, a handheld device such as a PDA, a cellular phone, a smart phone, a tablet PC with a GUI (Graphic User Interface), or a fixed device such as a PC.

The address setting unit 410 includes the Zigbee communication module itself or the Zigbee communication module, so that the Zigbee communication module is not connected to the communication module 422 of the program switch, Set the address.

Further, the address setting unit 410 sets an address of an illuminating device which is not addressed or which needs to be reset after the address setting, as described above, through individual Zigbee communication with each illuminating device having the Zigbee communication module .

In the address setting process, the program switch 420 and each lighting device can communicate with the address setting unit 410 according to a first address, that is, a basic channel and a basic PAN identifier at the time of initial address setting or address resetting .

Then, the program switch 420 and each luminaire are communicated with the address setting unit 410 as the first address, and then receive the second address to be changed and set to the received second address. The program switch 420 and each lighting device can store the received second address in a memory.

The program switch 420 includes a communication module 422 for Zigbee communication and a control module 424 for controlling each lighting device.

The control module 424 controls, for example, dimming intensity control, on / off control, and the like of each lighting device. For this control, the address setting unit 410 or the controller (not shown) It may receive and store the address information of the illuminating devices within the range that can be controlled by the controller 420.

In addition, the control module 424 receives control signals for each lighting device from the controller or address setting unit 410 based on the received or stored address information, and controls the corresponding lighting device to perform an operation according to the control signal can do.

The aforementioned illuminating device may include, for example, a light emitting unit, a sensor, and the like.

In the above process, a gateway (not shown) may be used for communication between the address setting unit 410, the program switch 420 and the illuminating devices 431 to 43N.

As described above, according to the present invention, the address setting unit uses the installation tool to input the zigbee network information to be installed through mutual communication using the installation channel, that is, the common channel and the basic PAN identifier (ID) By setting the address of the device, it is possible to control the smart wireless lighting system through quick installation and systematic address management and quick and effective communication setup.

This is because, when using only the MAC (Media Access Control) and the ZigBee network address, the wireless lighting control system can hardly find the device at the set address and takes a long time. Also, since the address management of the device is inconvenient and difficult, there is a problem that the address management is complicated and the time required at the time of setting is large.

FIG. 5 is a block diagram illustrating a detailed configuration of the address setting unit 410 of FIG. 4. Referring to FIG. Here, the light emitting unit 590 is illustrated in the address setting unit 410 for the sake of convenience.

Although not shown, such an antenna 510 may be replaced by a communication module for communication with the address setting unit 410, the lighting controller, the control module 424, the illumination units 431 to 43N, and the like. For example, the address setting unit 410 includes a communication module for supporting various communication protocols such as ZigBee, RS-232, RS-485, IP, LAN, LTE, Wifi, Wifi-direct, And may be provided separately or separately from the antenna 510.

The filter 520 is, for example, a low pass filter (LPF) that removes the harmonic component of the output and filters the high frequency component.

Transformer 530 may use a balance to unbalance transformer (Balun) to match a high impedance balanced antenna to a low impedance unbalanced receiver, transmitter, or transceiver.

The transformer 530 may be, for example, a 100 ohm differential signal, which converts the 100 ohm impedance to a 50 ohm impedance to the antenna according to the transmit / receive signal It can be filtered and matched to pass only the 2.4 GHz band.

The control unit 540 may be a 2.4GHz ZigBee wireless communication transceiver system on chip (SoC) with an IEEE 802.15.4 MAC / PHY in conjunction with the present invention.

The control unit 540 may also include a processor, a flash / memory (FLASH / SRAM), and an encryption unit. In addition, the control unit 540 may use an SPI (Ethernet, EEPROM), a TWI (RTC module), or a JTAG (SIF) interface. Also,

The memory 550 may include an electrically erasable programmable read-only memory (EEPROM), which is a kind of non-volatile memory.

The memory 550 may have a capacity of, for example, 128 Kbytes and may be used as a temporary data ROM when the ZigBee firmware is updated wirelessly.

The driver 560 is used for long distance communication with an external device in a differential line in a half duplex scheme in UART communication.

The buffer unit 570 can adjust the brightness of an external device (for example, a dimming connector) by a pulse width modulation (Pulse Width Modulation) method, for example, with a pulse width of 500 Hz.

A low dropout regulator (LDO) 575 constant-voltageises the input 5Vdc power to 3.3Vdc to supply power such as a ZigBee chip component.

The I / O port 580 is connected to twelve light emitting units through a half duplex type RS 485 communication, and can be individually controlled. The external device + 5Vdc is supplied to drive the internal circuit.

The I / F connector 585 receives the 5Vdc power through an external device (for example, a connected dimming connector), outputs a 5V PWM signal, and dims it by pulse width modulation (PWM) .

In addition to the above-described configuration, the bridge device 410 performs a function of testing a connection state between devices or fusing the device to a memory. In connection with the present invention, the bridge device 410 downloads a ZigBee software program (ZigBee S / W program) (JTAG) connector that performs download and debug functions of the JTAG connector.

6 is a flowchart illustrating an embodiment of an address assignment method in a lighting apparatus.

Referring to FIG. 6, all the communication lines of the address setting unit and the program switch and / or the lighting device (s) are connected (S102). In step S102, the address setting unit is connected through the ZigBee communication between the program switch and / or the illuminating device (s), and other communication protocols such as RS-485 as well as ZigBee may be used between the illuminating devices.

Accordingly, each of the components may have communication modules required to support the corresponding communication protocol.

Meanwhile, the connection in step S102 of FIG. 6 may be connected through a predetermined common channel or a basic channel (hereinafter, referred to as a common channel) when the installed lighting apparatus (s) are manufactured and shipped from the factory. Such a common channel is for address allocation or other information exchange even though, for example, an illuminator is not assigned an address as a predetermined channel between transmitting and receiving ends.

The address setting unit broadcasts a packet inquiring, through the connected communication line, whether the address setting is necessary to the program switch and / or the lighting device (s) through step S102. At this time, the program switch and / or the lighting device (s) which have received the packet of the address setting unit confirms the corresponding packet through an address packet or a PID (S104).

If it is determined in step S104 that the received packet is not an address packet, the process terminates. If the received packet is an address packet, it is determined whether the received packet is address data (S106).

If it is determined in step S106 that the address data in the address packet is included, the program switch and / or the lighting device (s) parse the address data and store the address data in step S110.

On the other hand, if it is determined in step S106 that the address data in the address packet is not included, the program switch and / or the lighting device (s) transmits the address request packet to the master device, i.e., the address setting unit (S108).

The address setting unit transmits an address packet including address data to the corresponding program switch and / or the lighting device (s) according to the address request packet received from the program switch and / or the lighting device (s) The address data in the address packet transmitted from the switch and / or the lighting device (s) is read and stored (S110).

In the above description, steps S104 and S106 may be performed in one step. For example, all packets transmitted between the address setting unit and the program switch and / or the lighting device (s) have a predetermined PID. Thus, the program switch and / or the lighting device (s) may be configured such that, after the communication line is connected in step S102, the address setting unit broadcasts an address packet asking whether to set the address, If the packet is parsed and the PID is read, the type and attribute of the packet can be grasped immediately. Therefore, the program switch and / or the lighting device (s) may not need to separately determine the presence or absence of address data in the address packet, as in step S106.

On the other hand, before the step S104, the address setting unit can continuously broadcast address packets periodically or non-periodically. This may be because, for example, there may be an error in previous broadcasts due to network conditions, or a device in which a program switch and / or a lighting device (s) has a problem in the middle, a replaced device, It is necessary to continuously check the device for the address setting periodically or non-periodically as described above. In addition to the above, in order to cope automatically when a group setting or an address change due to occurrence of an event is required by a user's request or the like,

In addition, the above-described broadcast may be necessary to determine a network state in advance to provide a faster and more adaptable service for controlling a lighting apparatus according to a request of a user or the like.

7 is a flowchart illustrating another embodiment of an address assignment method in a lighting apparatus. Here, FIG. 7 may be the detail address allocation method of FIG. 6 described above.

One embodiment of a lighting device control method according to the present invention includes the steps of receiving a packet of an address setting inquiry into at least one of a lighting device and a program switch in a first communication mode, Generating a random identifier for address setting in the second communication scheme and transmitting the random identifier to the address setting unit, and receiving and storing address data and setting an address.

Here, if the transmitted random identifier is the same as the pre-assigned identifier, the step of requesting regenerating and re-transmitting the random identifier to at least one of the lighting device and the program switch may be performed.

And receiving a control signal for controlling at least one of power on / off, dimming, and color temperature based on the set address data.

In addition, the address setting unit may provide a list-up GUI by sorting the random identifiers of the illuminating devices received through the visible light communication module according to the signal intensity of each illuminating device, The identification information request for discriminating whether or not the corresponding equipment is selected for the lighting equipment selected on the list of the GUIs, Lt; RTI ID = 0.0 > on / off < / RTI >

And the address data may include at least one of a channel, a device identifier, a PAN ID, and an extended PAN ID for at least one of the illuminators and the program switch, and wherein at least one of the illuminators and the program switch Stores the generated random identifier and the allocated address data, and transmits a packet and / or a predetermined number of power on / off repetitions so that address setting is completed when address setting is completed after storing the address data The method comprising the steps of:

In addition, in the present invention, at least two or more different communication methods can be used for lighting device control. For example, the first communication method is a Zigbee communication method, and the second communication method is a visible light communication method .

7, the master device refers to at least one of a lighting controller, a bridge device, a ZigBee gateway, a control means, etc., and the local control device For example, a program switch and / or a lighting device (s).

In addition, the master device includes a server concept. Although not shown, the master device may further include other control means, a cloud server, or the like through a communication network such as an IP or the like, so that address assignment, dimming, color temperature, On / off, and the like. A user connects to a cloud server or a service server provided by a manufacturer through a mobile device from outside, for example, through a master device in a home or a building through a pre-assigned or promised URL, Control may be performed.

Hereinafter, the address allocation method will be described in more detail with reference to FIG.

Meanwhile, one or more communication protocols may be used in the address assignment process between the master device and the local controller device. In FIG. 7, two communication protocols such as Zigbee communication and visible light communication are used for convenience. But is not limited thereto.

When a local control device is installed in a building or a home, all the local control devices can communicate with the master device even though each local control device has no address in its initial state. This is because, as described above, each local control device has information on a promised public channel at the time of shipment, for example, so as to allocate addresses.

In this process, for example, in the case of a local control device whose manufacturer is different or has an error, it may be filtered in the system. For example, if addresses or information of promised public channels differ from each other according to the manufacturer, the local control devices of other manufacturers may be filtered through the same. Such local control devices of other manufacturers may cause problems such as power problems or system errors due to differences in manufacturers from the intended local control devices installed in the building or home, for example, It may be necessary.

The master device sends a packet to the local control device via the ZigBee communication to inquire whether the address information is present (S202), and each local control device returns a packet including the response information corresponding to the packet (S204). Here, the packet transmitted by the master device may be an address setting request packet for transmitting the packet in the predetermined period or non-periodicity in FIG. Accordingly, when receiving the address setting request packet, each local control device parses the corresponding packet, determines the type or attribute of the packet through the PID, and then determines whether the address setting is required, It checks whether there is stored address information, generates response information therefrom, and returns it in the form of a packet. In this case, if each local control device has completed its address setting, it may or may not return a packet indicating that the address setting is completed.

If the local control device needs to set the address, the local control device returns the packet including the address setting request information as response information in S204.

After the return, as described above, each local control device generates a random ID for a predetermined communication method, i.e., automatic address allocation according to visible light communication (S206).

Each local control device generates a node ID packet including the random ID generated in step S206 and transmits it to the master device (S208).

When receiving the node ID packet from each local control device through step S208, the master device performs each local control device identification procedure.

For example, the master device determines whether the random ID in the node ID packet transmitted from the local control device overlaps with the random ID of the other local control device (S210) If the random ID is overlapped with the random ID of another local control device, the local ID is duplicated in the local control device, so that a new random ID is requested to be regenerated and retransmitted (S212).

On the other hand, if the random IDs are not identical, that is, if the random IDs are not duplicated, a packet containing the ON / OFF repetition command is transmitted to the corresponding local control device (S214).

Upon receiving the packet in step S214, the local control device stores the random ID generated in step S206 as its own unique ID, that is, the Zigbee unique ID (S216). The random ID stored in step S216 may be uploaded to a cloud server, a web server, or the like, thereby minimizing the possibility of overlapping with a random ID assigned to another local control device and reducing the load of the entire address assignment process.

After the packet transmission in step S214, the master device performs an identification check procedure for the local control device, but if it is not the device, the master device can perform an on / off command for the local control device with the next signal strength (S218). In step S218, the same result is obtained even if the result of the random ID check for the device is found to be correct, for example.

In step S218, the master device generates at least one of address data, i.e., device ID, information on a communication channel other than the common channel, a PAN ID, an extended PAN ID, etc., for the finally confirmed local control device And transmits an address packet including the generated address data to each local control device (S220).

Then, each local control device may check whether the address data is erroneous according to the address data of the master device via step S220. As a result of the check, if there is no network problem with the master device, the corresponding address information is set and stored.

The stored address data is address information used for control of a master device or the like at a later time, and thus various master devices can control the corresponding local control device, that is, power on / off, dimming level, color temperature Level, and group setting / release.

On the other hand, the master device arranges each local control device for each intensity of the electric wave for each local control device received through visible light communication and provides a list. Here, if the same signal strength is input, the local control devices are arranged in the order in which signals are received. This may be due to visible light communication and may be located close to the control means or the like.

On the other hand, the local control device having the greatest radio wave intensity is checked by on / off repetition (blinking method in case of a lighting device). If the local control device is not the desired local control device, the next signal is passed to the local control device. In this way, the user can additionally determine the location of the local control device which he wants, that is, the intent of the local control.

Stores the unique address in the corresponding control device and connects the rear end communication line.

The master device transmits an automatic address control packet to repeat the above-described random ID generation process and the like. Accordingly, the local control device having the address already does not correspond to the automatic address control packet, so that the address can be sequentially allocated.

8 to 11 are diagrams for explaining an embodiment of a GUI (Graphic User Interface) provided on the address setting unit 410 for address setting and control processes.

Figure 8 illustrates, for example, a GUI and item (s) for setting up a ZigBee network.

Items for setting up the ZigBee network include Channel, PAN-ID, Ext. PAN-ID, device address, and the like.

Each item will be described as follows.

The Channel item selects a specific channel among the available range of channel information.

The PAN ID field is for inputting an ID identifying the corresponding PAN to which the ZigBee network is to be set.

The Extended PAN ID field can receive a preset value for security.

The Device Address field receives the address of the desired device.

By doing so, it is possible to control not to join the channels other than the set values and other ZigBee devices set to the PAN ID.

Depending on whether the GUI of FIG. 8 is for address setting or lighting device control, the values of each item described above may be different from each other.

For example, if the GUI of FIG. 8 is provided in the address setting process, the channel is automatically or manually entered as the default channel, that is, the common channel used before the address setting, between the address setting unit and the illuminator. On the other hand, if it is the lighting device control process after the address setting, the channel is automatically or manually input the channel pre-assigned to the lighting device.

On the other hand, the PAN-ID is for identifying the PAN to which the lighting apparatus belongs, and may or may not have the same meaning as the group unit used in this specification.

As described above, the extended PAN ID item is difficult to distinguish, for example, from an error or a lighting device manufactured or shipped by a manufacturer by using only the item (s), that is, the channel and the PAN-ID item, Or an error in the lighting apparatus or the system. Accordingly, it is preferable that the extended PAN ID item is assigned a unique value so as to be classified according to the attribute or type of, for example, the manufacturer or the lighting device.

The device address can be set to be selectable even if the user does not set the device address, for example, by providing an address list of available devices according to at least one of the input channel, the PAN-ID, and the Ext PAN-ID for convenience of the user .

Fig. 9 is the next GUI of Fig. 8 described above, for example, a conform GUI for determining whether to set the network / address after completion of entry of item (s) in Fig.

Referring to FIG. 10, when an address setting is requested through FIGS. 8 and 9, the control means, that is, the address setting unit transmits a random ID and then performs pairing through visible light communication, that is, Unconfigured luminaires are listed. On the other hand, as shown in FIG. 7, such a list of lighting apparatuses can be displayed sequentially, for example, according to the signal intensity of each lighting apparatus received.

In FIG. 10, for example, if the user does not make a selection among the listed unlabeled addressing luminaires for a predetermined time, he or she switches to a stand-by state in order to reduce power consumption, A sub-GUI for address setting of a strong lighting device can be provided as shown in FIG. In the former case, when the user presses a predetermined button again in the standby state, it is possible to provide a standby screen or a home screen.

On the other hand, the unaddressed address list of FIG. 10 is not fixed, but may be flexible depending on, for example, the movement or movement of the user. For example, the list in the GUI provided on the screen of the address setting unit of Fig. 10 must be received so that the address can be set through the address setting unit through at least visible light communication. Otherwise, errors may occur in the setting process due to the weak signal strength.

If the user continues to move at a predetermined position, the address unlit illuminator with signal strength less than the threshold may be deactivated in the list or displayed or deleted from the list.

On the other hand, if the user selects a lighting device that is likely to be inactivated or deleted from the list due to a weak signal intensity from the list, that is, a threshold value, the signal intensity is weak It may be advisable to notify the user through the pop-up that an error or a problem may occur, or to advise the user to move in some direction in some direction to set the address of the lighting device.

FIG. 11 shows that, when at least one illuminator is selected from the address unset illuminator list provided through the GUI of FIG. 10, for example, a sub-GUI for address setting of the selected illuminator is provided.

Here, the sub-GUI can provide selectable items such as, for example, a Join Enable packet transmitted in a unicast manner, a network setting, an address setting, a ZigBee member setting, a power on / off, a software or a firmware update .

In particular, the Join Enable packet may be a packet that broadcasts whether or not an address setting is required to the selected lighting device, as described above. When the packet is received, the corresponding lighting device may return a packet corresponding to the packet, that is, an address setting request or non-request information.

As described above, according to the present invention, even if a plurality of lighting apparatuses are connected to the lighting control means at a time to allocate or control addresses to the lighting apparatuses installed in the building, each lighting apparatus can be easily identified, Can be controlled.

The foregoing description of the preferred embodiments of the present invention has been presented for purposes of illustration and various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention, And additions should be considered as falling within the scope of the following claims.
