The XML interface 210 receives device data corresponding to the exhibition / performance device to be registered among the plurality of exhibition / performance devices 400a, 400b,..., 400n. For example, when the first exhibition / performance device 400a is to be registered on the system controller 200, the XML interface unit 210 stores a plurality of device data DAT1, which are stored in the database 300. The first device data DAT1 corresponding to the first exhibition / performance device 400a among the DAT2,..., DATn may be received.

In one embodiment, at least two or more protocols may be overlapped in forming the first connection method for communication between the system controller 200 and the first exhibition / performance device 400a. For example, the DMX512 protocol used for the lighting device and the MIDI protocol used for the sound device may be modified with the Artnet protocol and the RTP-MIDI protocol by overlapping with other protocols when transmitting through Ethernet. Specifically, an example of the DMX512 protocol is that the DMX512 protocol transmits one byte (ie, 8 bits) 512 bits at a time in one command, and thus 64 commands can be issued simultaneously. In order to transmit the DMX512 protocol over Ethernet, when the UDP protocol is overlaid on the DMX512 protocol (that is, overlapping), the Artnet protocol is modified, and the Artnet protocol includes bits including additional information of 512 bits of the DMX512 protocol. Is added. When at least two or more protocols are overlapped and used, the nested protocol is specified in the first device data DAT1 configured in XML format, and the connection processor 240 may specify the nested protocol. have. Therefore, the reusability of the device expressed in the XML format can be improved.

3 is a diagram illustrating an example of a transport packet generated according to embodiments of the present invention.

Referring to FIG. 3, a six-byte transport packet containing six instruction units is shown. The transport packet shown in FIG. 3 consists of one instruction, one parameter, one delimiter and three terminators. Each command unit may be data expressed in the form of hexadecimal number Hex.

In the transport packet of FIG. 3, the terminator is disposed at the forefront and the foremost. For example, a leading character (STX) having a start value and having a value of 0x02 is disposed at the very beginning (0 bytes) of the transport packet, and an end of the packet is indicated at the rear end (5 bytes) of the transport packet. A terminating character (ETX) with a value of 0x13 may be placed. At the rear end (1 byte) of the preceding character (STX), a command for controlling an exhibition / performance apparatus is arranged. For example, a command 'Power On' used to power on the exhibition / performance device and having a value of 0x4A may be arranged. At the end (2 bytes) of the command ('Power On'), a delimiter having a value of 0x01 is used to distinguish a command from a parameter.

At the end (3 bytes) of the separator, a parameter that can be set by the user is arranged. For example, when the user (10 of FIG. 2) inputs the setting value '51' through the user interface unit 250 ', the user (10 of FIG. 2) includes the command unit editing unit 234' of the command processor (230 of FIG. 2). The parameter conversion block 236 may convert the setting value '51' to a value of 0x33, which is a hexadecimal number, based on a preset parameter conversion function. The set value may indicate the volume of the sound device or the brightness of the lighting device. The user interface unit 250 ′ may include input means such as a keyboard, a keypad, a touch pad, a mouse, and an output means such as a display. According to an embodiment, the parameter conversion function may be implemented to be editable by a user.

The terminator is placed after the parameter (4 bytes). For example, the calculation block 238 included in the command unit editing unit 234 'of the command processing unit 230 (Fig. 2) is used to check the integrity of the transport packet based on a preset calculation function and has a checksum having a value of 0x7E. Can be generated. In the embodiment of Figure 3, the calculation function may correspond to "value of command + value of parameter + 1". According to an embodiment, the calculation function may be implemented to be impossible to edit by a user.

Although FIG. 3 illustrates that a transport packet includes all of an instruction, a parameter, a delimiter, and a terminator as a component, the transport packet may not include some types of components according to an embodiment. For example, a transport packet may not include parameters and / or delimiters. In addition, although FIG. 3 illustrates that a transport packet includes one parameter, according to an embodiment, the transport packet may include two or more parameters. In FIG. 3, the data is shown in hexadecimal form, but according to an exemplary embodiment, the data may be represented as arbitrary binary data.

In the control method of the exhibition / performance device according to the embodiments of the present invention, the system controller for controlling the exhibition / performance device, and the exhibition / performance system comprising the same, by using the four types of components described above A general representation of one transport packet or response packet may be possible. For example, in the MIDI protocol, a packet may consist of "command (ie command) + parameter 1 + parameter 2", and in the DMX512 protocol, a packet may consist of "address (ie command) + parameter", In the RS232 protocol, a packet may be configured to include 'NUL (\ 0)' or 'CR 13' as a terminator. Thus, using commands, parameters, delimiters, and terminators may allow for universal representation of any packet.

4 is a diagram illustrating an example of an XML structure of device data used in embodiments of the present invention.

Referring to FIG. 4, in the XML structure of the device data, the first child element <Protocols> specifies the protocol of the corresponding exhibition / performance device. At the bottom of each <Protocol> included in <Protocols>, the corresponding protocol setting is described as <Data>. Specifically, the third <Protocol> of each <Protocol> specifies that IP and RS232 are overlapped. In the case of overlapping use as described above, the overlapping method may be specified at the bottom. The nesting method can be different according to the implementation method, and a separate function can be implemented by serialization through BASE64.

The second child element, <CommandList>, specifies the control commands for controlling the corresponding display / performance device. Each <Command> contained in the <CommandList> is a control command, and has a direction as an attribute, and in addition, ID (Identification) and reference ID (ReferenceID) as attribute values. The reference ID may be useful when transmitting a status query signal to a display / performance device and receiving status information. That is, after transmitting the status query signal to the exhibition / performance device, the device's response to the signal may be processed as an input to the query signal. In the embodiment of FIG. 4, when the 'Volume Check' is transmitted to the exhibition / performance device to check the current volume, the response is recognized as 'Volume CheckIn', which is a response to the previously transmitted 'Volume Check'. That is, it may be implemented to recognize that the information of the current volume status.

In the lower part of <Command>, the packet setting is described as <Type>, and in particular, a command, a parameter, a splitter, and a terminator are specified. For example, 'Power On' of FIG. 4 may correspond to the transport packet of FIG. 3. The binary data value to be transmitted or received may be expressed in the form of hexadecimal number (Hex) according to the transmission order. Parameters and terminators can specify a parameter conversion function and a calculation function, respectively, according to the property value of 'Converter'.

The third child element, <Converters>, describes the information of the parameter conversion function or the calculation function, which can serialize the software module itself to the BASE64 format to hold the entire drive module. Type).
