BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a reconfiguration method and system for an RF channel and a device address of a wireless DMX512 device by bidirectional communication,

One embodiment of the present invention is directed to a method and system for enabling wired DMX512 devices to bidirectionally enable wireless communication without degrading performance and protocol changes.

Conventional wired DMX512 devices have input and output terminals, and output terminals of the DMX512 device are connected to the input of the next DMX512 device.

First, the DMX512 device receives input from the control console corresponding to the main control unit. The connected circuit structure is multi-drop type, which limits the number of DMX512 devices that can be connected to one network at the maximum. The maximum number of DMX512 units that can be connected is affected by the EIA-485 driver IC used in the unit.

In addition, the cable work required to connect each DMX512 device at the installation site has a lot of time and complexity. If several DMX512 devices are connected in a dependent manner, all DMX512 devices can be a problem in the event of an intermediate cable failure.

In addition, when the existing wired DMX512 device is installed in a position difficult to access, it is very inconvenient to change the address because the DMX512 device must be directly accessed and operated by a person.

An embodiment of the present invention is to solve the problems of existing wired systems, and to implement data communication between a control console, which is a DMX512 master, and a lighting device corresponding to a slave, using bidirectional wireless communication.

In addition, we propose a method and system that can transfer remotely address by transmitting DMX 512 standard up to 44Hz refresh rate without frame loss and using wired / wireless address.

Embodiments of the present invention allow a DMX 512 channel to be easily expanded using a plurality of wireless channels and can be used in combination with a conventional wired DMX 512 while meeting the standard of the wired DMX 512.

In another aspect, the configuration information includes slot information for a used channel, an address, and may be stored in the second storage unit together with a wireless hardware address (MAC address).

In another aspect, the master may transmit a CRC code (Cyclical Redundancy Check Code) when transmitting DMX 512 data.

In another aspect, the slave determines whether there is an error by using a CRC code, and if an error occurs, the slave can prevent malfunction of the lighting device due to an error generated using previously received DMX 512 data.

In another aspect, the master receives commands including a starting RF channel, an end RF channel, a starting slave radio address, and an ending slave radio address from the configuration GUI, and sets the radio channel of the master to the starting RF channel Start Slave You can find the slave by sending a command starting with the wireless address.

Hereinafter, the operation of the reconfiguration system and the system of the RF channel and device address of the wireless DMX 512 device will be described in detail with reference to the accompanying drawings.

Figure 1 shows a block diagram of a proposed system 100 in one embodiment of the present invention. In an embodiment, a signal generator 110 for generating a DMX 512 wire signal, a data generator 130 for generating DMX 512 data in software, and DMX 512 data generated from the data generator 130, And a gateway 120 for transmitting to the master 140.

Here, the DMX 512 wired signal may correspond to a wired signal of a conventional DMX 512 device, which may be connected to a plurality of masters 140 as cables, and is displayed as a solid line to control and monitor the slave 150 device, Signals for integrated transmission of data are indicated by dotted lines.

Various communication interfaces such as TCP / IP, ZigBee, BlueTooth, Wi-Fi, TCP / IP, RS485 and RS232 can be used as the integrated transmission signal. In addition, both the dotted line signal and the solid line signal can be configured by the user's choice. In addition, the configuration using the integrated transmission signal can be highly evaluated for convenience because the control signal and the DMX 512 data can be connected through a single communication interface.

As shown in FIG. 1, the DMX 512 data may be divided and transmitted through two radio frequency channels as a pair of masters 140 divided into (a) and (b). This is aimed at increasing the transmission distance of the wireless data packet by lowering the wireless data transmission rate and securing the spacing between the wireless packets to minimize the loss rate.

The DMX512 packet has a frame refresh rate of up to 44 Hz at a rate of 250 kbps. In the case of wireless transmission, in order to transmit data without delay or frame loss, the wireless data transmission rate needs to be higher than the transmission rate.

If the transmission speed is equal to or lower than 250 kbps, it is necessary to divide and transmit 512 bytes of data using several masters, so that data can be transmitted without transmission delay and loss. When the DMX512 frame is divided and transmitted at a low wireless transmission rate, the number of channels will increase. Therefore, in the embodiment of the present invention, DMX 512 frames can be divided and transmitted using two masters at a wireless transmission rate of 250 kbps.

As shown in the figure, the master (a) transmits 1 to 256 slots and the master (b) transmits 257 to 512 slots. Clusters that are a set of slaves corresponding to each master are assigned the same radio frequency channel. Slaves using the same radio frequency channel can simultaneously receive the same data from the same master and transmit the received DMX 512 data to the lighting equipment.

At this time, the 256 slots transmitted by the master may be filled with data generated arbitrarily by the slave device, but this is not a problem since the slot of the corresponding area is not used in the lighting device.

This description assumes that the illuminator uses one DMX512 slot. In actual cases, one lighting apparatus can use a plurality of slots. For example, in the case of a stage LED lighting device, 10 or more slots are assigned to one lighting device such as RED, GREEN, BLUE, and a motor for controlling the color control and the direction of illumination.

2 is a block diagram illustrating a detailed configuration of the gateway 120 shown in FIG. 1, according to an embodiment of the present invention. The DMX512 gateway 120 is a device for converting a signal to transmit the DMX512 wire signal to the communication unit of the master.

The DMX 512 receiving unit 121, which is composed of multiple channels, can receive the DMX 512 wire signal. The gateway 120 includes a communication unit 122 for receiving the signal and converting it into various communication systems, And a control unit 123 for controlling the entire operation. At this time, the communication unit 122 can use a communication interface such as TCP / IP, ZigBee, BlueTooth, Wi-Fi, RS485, and RS232.

3 is a block diagram for explaining the detailed configuration of the DMX 512 master 140 according to an embodiment of the present invention. The master 140 may be configured with a plurality of radio channels according to the transmission rate, and in the embodiment, the master 140 has two channels.

The DMX 512 wired signal received by the receiving unit 141 is a common input of multiple channels, and the dotted line portion 146 represents a module having one bidirectional wireless channel.

The communication unit 142 may be provided to set environment information of the bidirectional communication module or to receive data from the DMX 512 gateway 120 mentioned above. The communication unit 142 may provide various interfaces such as TCP / IP, RS485, and RS232. The master 140 can be directly controlled by this communication method or the slave 150 can be remotely controlled via the master 140. [

The storage unit 144 may correspond to the non-active memory in which the setting information is stored. The setting information may include a channel allocated by the master, the number of slave-allocated slots, channel information allocated to the slave, and the like.

The control unit 143 receives the DMX 512 signal and distributes it to 1/2, transmits it to the slave by radio, receives the input data through communication, and performs an appropriate operation according to the type of the received data. DMX 512 data can be received through the receiving unit 141 and the communication unit 142. In a system using the gateway 120 together, the communication unit 142 can transmit environment setting data and physical media such as DMX 512 data .

FIG. 4 is a block diagram illustrating a detailed configuration of a wireless DMX 512 slave according to an exemplary embodiment of the present invention. Referring to FIG. The DMX 512 may include a receiving unit 151 for receiving the DMX 512 wire signal and a transmitting unit 152 for outputting the DMX 512. The DMX 512 data packet and the configuration information may be transmitted from the master through the RF transmitting / .

The configuration information received from the master may correspond to the channel to be used, the slot information for the address, and the like. The information thus received may be stored in the storage unit 154 together with the wireless hardware address (MAC Address) 8 bytes. Wireless hardware address 8-byte data can not be changed from master to wireless, and is the only address in the system.

The control unit 153 may combine the wirelessly input data and reproduce it as a complete DMX 512 signal and wirelessly relay the complete DMX 512 signal input through wire to another slave.

This operation compensates for the attenuation of the radio signal due to the distance and the blocking of the obstruction by the obstacle (Repeater) so that the remote and shade lighting apparatus can be controlled with high reliability. The DMX512 data packet transmitted by the master is a broadcast concept packet that is received by all the slaves using the same channel at the same time.

 Thus, the slave may not respond to the packet to the master. However, the master transmits the CRC code to the DMX512 data packet so that the slave can detect packet errors on its own.

The slave determines whether a packet error has occurred by using a CRC code (Cyclical Redundancy Check Code) included in the DMX 512 data packet. If an error occurs, the previously received DMX 512 frame is retransmitted to the lighting device, It is possible to prevent a malfunction of the motor. That is, it is possible to retain the previous packet information and update it with the next packet information.

FIG. 5 is a diagram for explaining a process of finding a slave in operation to set an operating environment of a wireless DMX 512 system proposed by the present invention.

When the master 520 receives the slave search command 11 including the start RF channel, the end RF channel, the start slave radio address, and the end slave radio address from the GUI (program) 510 for wireless DMX512 system operation environment setting, May set its RF channel on the initiating RF channel and send the slave find command 12 to the slave 530 starting from the starting slave address.

The slave 530 transmits a response message 13 including the radio address (MAC) and RF channel information, the allocated DMX 512 slot information, and the RSSI to the master 520, . Master 520 may then send the same command to the next slave address on the same RF channel.

In this manner, it is possible to repeat the end slave address received from the GUI 510. When the operation to the last slave address is completed, the RF channel is changed (14, 15), and the above process can be similarly repeated. Here, the slave address is excluded.

5, since there are two RF modules in the master, it is possible to shorten the time to search for the slave by dividing the RF channel by 1/2 and proceeding in parallel. For example, if a slave is searched for 10 RF channels, RF channels 1 through 5 can be master (a) and RF channels 6 through 10 can be performed by master (b).

6 to 7 are flowcharts for explaining the process of changing the operating environment information of the slave. Here, FIG. 6 shows a flow chart on the master side, and FIG. 7 shows a flow chart on the slave side.

6, the master may receive an information change request message from the GUI (610). Then, in operation 620, an information change message including a radio channel number currently being operated by the slave may be transmitted together with the environment information desired to be changed. This allows a slave that wishes to change its own channel to send a message to the currently used channel. Here, the master can wait for about 2 ms to receive a response message from the slave in the same channel state.

If a response message is received from a slave that desires to change, a search message for searching for the slave can be transmitted by designating the channel value as an initial value (630). Upon arrival of the response message from the slave (640), the success report message is transmitted to the GUI as the successful change of the environment information (650), thereby completing the process of changing the environment information.

When a response message is received from the slave, the slave channel set for the change is also changed, and a search command can be transmitted to the slave.

However, if the slave is found, the process of changing the environment information is ended. Otherwise, the search returns to the previous channel. If the slave is found in the previous channel, the above process is performed again. If not found, the failure message can be transmitted to the GUI (660).

Meanwhile, the normal slave can perform the operation as shown in FIG. 7 in response to the message transmission shown in FIG.

An information change request from the master is received (710) and a response to the message may be sent to the master (720). After transmission, it waits for a response from the master, at which time it may wait for 2 ms (730). At this time, the search message may be received from the master, and the search response may be transmitted (740).

In an embodiment, the master may wait for the receipt of a response indicating that a corresponding find response has been received (750), and if the response arrives, the information change is successful (760) ).

When the process of changing the environment information is normally completed, the slave can repeatedly or arbitrarily generate an On-Off message in the DMX 512 frame to transmit the DMX 512 frame to the lighting device so that the user can easily confirm the installation location.

In addition, the slave may transmit the RSSI (Received Signal Strength Indicator) received by itself to the change request message transmitted by the master. This is to establish a reliable system by notifying the system user of the quality of the RF link between the master and the slave. In other words, a slave with a particularly low RSSI value changes the system installation structure using various topologies shown in the embodiments to be described later (distance reduction, wired replacement, wired / wireless hybrid use, etc.).

8 is a flowchart illustrating an operation in the case where a response message is not received from a slave according to an exemplary embodiment of the present invention.

6 to 7 to change the RF channel of the slave. As shown in the figure, the loss of the wireless data packet occurs in step 810.

If the wireless packet is lost in step 810 but the master determines that the slave has normally received data, the master RF channel can be changed to 3 in step 820.

However, since the slave has not received the 'ACK' frame for the response message in step 810, the slave can maintain the previous channel 2 (830). At this time, since the master maintains the changed RF 3 channel, it will not transmit the 'ACK' message.

Three timeouts are generated 840, and if there is no response, the master may report a failure message to the GUI 850. As shown in the improved wireless channel, the master and the slave can normally transmit and receive wireless packets (860, 870), and the master sets the GUI to the GUI successfully An acknowledgment message indicating that it has been completed (880) may be transmitted.

If the slave has normally received the response message in step 810, the packet can be normally transmitted and received without performing operations in steps 820 to 840. [ In this case, the RF channel is changed without error from 2 to 3, and the GUI can receive a message for normal performance.

FIG. 9 is a flowchart illustrating an operation in which the slave find message is not received after the slave channel is normally changed by applying the algorithm of FIG. 6 to FIG. 7 in an embodiment of the present invention.

(920) a packet loss occurs during a slave discovery request message operation after a slave normally operates (910) for a channel change request transmitted by a master. If all of the slave discovery request messages are failed by the wireless channel environment (910), the master can regard the failure of the slave RF channel to be unsuccessful even though the RF channel of the slave is normally changed and deliver the RF channel change failure report to the GUI 930).

Thus, the GUI may once again attempt to request a change to the same RF channel (940). However, the slave does not receive the new channel change request message 950 because the channel has already changed in the previous channel change request message operation 910. The master may then send an RF channel change failure report to the GUI (960). At this time, the user can repeatedly request the channel change by repeating the same method, but the slave search request can be transmitted to the start RF channel, the end RF channel, and the corresponding slave address to search for the slave (970).

In this case, the master sequentially scans the requested channel (980) and confirms that the slave has changed to the channel 3 as shown, and reports it to the GUI.

The present invention can be applied to a conventional wired type lighting system such as a stage lighting system and a landscape lighting system using the DMX512 protocol, and a module implemented in the present invention can be applied to a lighting apparatus used in a conventional wired system .

FIG. 10 illustrates various topologies configured by wired / wireless in an embodiment of the present invention.

In the illustrated topology, a case in which all the raves are configured wirelessly (1010), a case in which radio waves are mixed (1020), a case in which a radio signal is changed to a wired channel, and a case where a wireless signal is retransmitted (1030) is illustrated.

A method of changing the DMX 512 signal to a wired line and then retransmitting the DMX 512 signal to the wireless line (1030) when the lighting apparatus is installed at a distance from the obstacle 101 or the master of the wireless signal may be used.

When changing the RF channel and the environment information through the wired network 102, the slave node 102 at the terminal connected to the wired network plays the role of the master. At this time, since the existing lighting apparatuses 103 can be connected to the wired line, it is possible to distinguish the start code (START CODE) corresponding to the first slot of the DMX 512 frame from the DMX 512 frame with a value other than '0x00'.

Another defined star code defined and used in the DMX512 standard is the code (0xCC) used to extend the existing DMX512 standard in character packet transmission (0x17), for system information (0xCF), and in Remote Device Management (RDM) . Therefore, in the embodiment of the present invention, '0x11' can be used among those excluding these values.

11 to 13 are diagrams for explaining the concept of remote address allocation proposed in the present invention in an embodiment of the present invention. The basic principle of remote address allocation is a method of converting the slot order of a wired DMX 512 frame restored by a slave into a sequence (order) of a slot allocated to the wireless address of the slave by the master and transmitting the sequence.

11, it is assumed that eight lighting apparatuses are installed, and it is determined by the wired address, the wireless address, the slot remotely assigned to the wireless address by the master, and the wired address, , And when a slave sends a DMX 512 frame to a lighting device, the slot sequence, which is the order in which the slot is sent, is organized.

It is assumed that the number of valid slots to be processed by the lighting apparatus is ten. Assuming that the wire addresses are set to 1, 1, 1, 41, 51, 61, and 71 as shown in FIG. 11, the effective slot numbers to be processed by each lighting apparatus are as shown in the table.

In a conventional DMX 512 system, the number of slots processed by the illuminator and the valid slot numbers processed by the illuminator by the wire address can be determined. When a slave transmits a DMX512 frame to a lighting device without transmitting the slot sequence, the effective slot number below will be the slot number processed by the lighting equipment.

If the user wishes to assign a new slot to each luminaire remotely while the system is being installed wirelessly or during use, the slot can be newly assigned to the wireless address (this is the assumption for the user to assign the desired slot ). When the slot for the new wireless address is newly allocated, the slave can map the slot allocated to the wireless address to the effective slot position determined by the wire address, and transmit it to the lighting device. This means that new slots will be remotely allocated.

Hereinafter, the illumination 1101 will be described in detail. Since the wire address of the slave of the light 1101 is set to 61, it is possible to process 10 slots 60 to 70 from the 61st.

And, the sine address of the slave coupled to the illumination 1101 is 7, which is the only value on the whole system. The user can remotely assign the new slots 131 ~ 140 to this slave 7 address. The slave inserts the slots 131 to 140, which are remotely allocated slots, into slots 61 to 70, which are slot positions determined by the wire address, and transmits them to the lighting device. In other words, slots 1 to 60 of the wireless DMX 512 frame sent from the slave to the lighting device are transmitted, and slots 131 to 140 allocated to the wireless address are transmitted to slots 61 to 70, which are slot positions determined by the wire address.

Then, it sends slot 71 ~ 130 which is the original position. The slot position is then slot positions 131 to 140. In this position, it is possible to resend 131 ~ 140 slots previously sent to slot positions # 61 ~ 70, or 61 ~ 70 slots not sent at previous slot positions # 61 ~ 70. This may correspond to the option of remote address assignment. The next slot position is at position 141. Since there is no part to be changed, the subsequent slots are sequentially transmitted from slot 141 to slot 512.

FIG. 12 is intended to explain a more extended application of the above-described concept to rearrange and rearrange the slot sequence as a whole. The master can rearrange and transmit the entire slot sequence.

For the same information as in Fig. (A), the previous figure (b) shows the slot sequence sent by the master, and the latter shows the slot sequence rearranged by the slave.

FIG. 13 is a diagram for explaining the contents of FIG. 11. The wired address 1310 is an address for assigning a slot to be used by the lighting apparatus in the existing wired system. This is typically set manually by the user and is included in all existing wired DMX 512 devices.

The wireless address 1320 is an 8-byte hardware address that the slave inherently has. In an embodiment, the wired address 1310 and the wireless address 1320 may be used together to remotely allocate a slot.

If the wired address 1310 is set to be the same as shown, the lighting apparatus of the existing wired system will be allocated the same DMX 5812 slot and perform the same operation. However, in the embodiment of the present invention, by using the remote address allocation scheme sequence, different slots can be allocated to each lighting apparatus using a unique wireless address even if the same wireless address is set.

In addition, even when the wired address 1330 is allocated differently, the slave may change the DMX 512 frame slot order to process the same slot in the lighting apparatus.

According to this embodiment, the DMX 512 standard can be mixed with the existing wired DMX 512 and the communication between the master and the slave can be bi-directionally wirelessly compensated for the disadvantages of the existing wired DMX 512 devices and the address of the lighting device can be allocated remotely Make it easy to install the system.
