Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dimming data processing apparatus that processes a dimming signal output from a dimming console and outputs the processed signal onto a predetermined signal line connected to a lighting device.
[0002]
[Prior art]
Conventionally, as shown in FIG. 14, the dimming signals output from the plurality of dimming tables 2 are derived from the dimming table 2 in order to output the dimming signals onto the plurality of signal lines to which the lighting device 3 is connected, respectively. A patch panel 21 for connecting each of the plurality of input terminals connected to the signal line and the plurality of output terminals connected to the signal line to which the lighting device 3 is connected, and the adjustment on one signal line. A dimming 22 comprising a split 22 for outputting an optical signal on a plurality of signal lines, and a MIX device 23 for selecting data having a high dimming level from two inputted dimming signals and synthesizing the data into one dimming signal. Optical wiring systems are known.
[0003]
As the above-mentioned dimming signal, USITT standard DMX512, which is a kind of RS485, is generally used, and the format of this signal is used to identify a break for finding the head of data and data transmission other than dimming data. Start Code, 512 Channels each including 255 levels of dimming levels, and Time Between Frame for partitioning each Channel. Channel is a data area for storing the dimming level data of the lighting devices 3, and since there are 512, 512 lighting devices 3 are connected per signal line, and each of the lighting devices 3 is connected. It is possible to control the light control level in 255 steps.
[0004]
Here, a DMX signal having five channels is taken as an example, and each device of the dimming wiring system will be described in more detail. The dimming console 2 has a dimming level as shown in FIG. When a desired dimming level is set by these faders 2a, these dimming levels are stored as data in each channel. Two DMX signals are output. The patch panel 21 is a device for manually switching the connection in order to connect a plurality of input terminals and a plurality of output terminals one-on-one, as shown in FIG. The input terminals (1) to (4) can be connected to any one of the output terminals (5) to (8).
[0005]
The patch panel 21 is a device that performs manual switching as described above. However, in the field of information wiring systems, for example, a device that performs switching automatically is disclosed in Japanese Patent Laid-Open No. 7-212375. The split 22 duplicates the DMX signal inputted from one signal line and outputs the duplicated DMX signal on a plurality of signal lines. For example, as shown in FIG. When a DMX signal in which dimming levels 0 to 4 are stored in channels 1 to 5 is input from {circle over (1)}, the signal is copied as it is, and output from channels {circle over (2)} and {circle over (3)} to channels 1 to 5. One DMX signal in which dimming levels 0 to 4 are stored is output.
[0006]
The MIX device 23 compares the data stored in the corresponding Channel for each corresponding Channel, such as Channel 1 and Channel 2, from the two input DMX signals, and the data with the higher dimming level is obtained. A device that selects and outputs one DMX signal on the signal line. For example, as shown in FIG. 15 (d), a DMX signal in which dimming levels 1 and 2 are stored in channels 1 and 2 and dimming level 0 is stored in the other channels is input from input terminal (1). When a DMX signal in which dimming levels 3 to 5 are stored in channels 3 to 5 and dimming level 0 is stored in the other channels from input terminal (2), channels 1 to 5 are 1 to 5 respectively. The DMX signal in which the dimming level is stored is output from the output terminal (3).
[0007]
By the way, in the above-mentioned dimming wiring system, when the number of inputs to the patch panel 21 and the number of signal lines are not the same, for example, the lighting device 3 on the signal line exceeding the number is adjusted with a small number of dimming consoles 2. When control is performed, the patch panel 21 is switched so that each lighting device 3 has a desired dimming level, and the split 22 and the MIX device 23 are combined as necessary to set the dimming table 2. It must be made. However, since the processing in each device of the above-described dimming wiring system is processing of the entire DMX signal, in other words, all channels are processed, changing the dimming level of the lighting device 3 on a certain signal line changes the setting. In spite of not wanting to do so, the lighting control level of the lighting device 3 on the other signal line is changed.
[0008]
More specifically, based on the dimming wiring system shown in FIG. 16 (a), as shown in the figure, the DMX signal output from the dimming console 2a is supplied to the channels 1 and 2 with dimming levels 1 and 2, respectively. On the other hand, dimming levels 2 and 1 are stored in Channels 1 and 2, respectively, for the DMX signal output from the dimming console 2b. In the patch panel 21, the input terminal (1) and the output terminal (3) are connected, the input terminal (2) and the output terminal (4) are connected, and the DMX signal output from the dimming console 2a is The DMX signal that is output on the signal line connected to the output terminal {circle around (3)} and output from the dimming console 2b is output on the signal line connected to the output terminal {circle around (4)}.
[0009]
Each signal line is connected to the splits 22a and 22b, and one signal line output from each of the splits 22a and 22b is input to the MIX device 23. Here, if the other signal lines output from the splits 22a and 22b are 24a and 24c, respectively, DMX signals in which dimming levels 1 and 2 are stored in the channels 1 and 2 are output on the signal line 24a. On the other hand, DMX signals in which dimming levels 2 and 1 are stored in Channels 1 and 2 are output to the signal line 24b. If the signal line connected to the output of the MIX device 23 is 24b, a DMX signal in which the same dimming level 2 is stored in Channels 1 and 2 is output on the signal line 24b.
[0010]
Accordingly, dimming levels 1 and 2 are assigned to the lighting devices 3a and 3b connected to the signal line 24a, respectively, and dimming levels 2 and 1 are assigned to the lighting devices 3e and 3f connected to the signal line 24c, respectively. Further, the same dimming level 2 is assigned to the lighting devices 3c and 3d connected to the signal line 24b. Here, considering that the dimming level of the lighting device 3c is changed from 2 to 1, in the dimming console 2, the setting of the dimming level of Channel 1 may be changed from 2 to 1, but by the split 22b Since it is branched, the dimming level of the lighting device 3e is also 1.
[0011]
At this time, there is no problem when the dimming level of the lighting device 3e is also set to 1. However, when the dimming level of the lighting device 3e is to be kept at 2, it cannot be realized with the current system configuration. A system configuration change is required. More specifically, as shown in FIG. 16 (b), the signal line 24b may be directly connected to the split 22a without using the MIX device 23 without changing the settings of the light control tables 2a and 2b. 22b becomes unnecessary. In addition, for the sake of simplicity, it has been described that two dimming tables 2a and 2b are provided, and dimming level data is stored in only two channels, and is output on the three signal lines 24a to 24c. Actually, more light control tables 2 are provided, and 512 channels are present as described above.
[0012]
[Problems to be solved by the invention]
Thus, in the above-mentioned dimming wiring system, in order to realize a desired dimming level, a combination of various devices such as the split 22 must be considered, and the dimming console 2 and the signal line are In a complex light control system with multiple devices, it requires skill in design and multiple performances are scheduled. If the interval between performances is short, the connection can be completed in a short time. In spite of having to do it, there is a problem that it is not possible to wire quickly. In addition, depending on the setting of the dimming level, it is necessary to provide a spare device in consideration of various effects, although the device such as the MIX device 23 may be unnecessary as described above. It was also not economically preferable.
[0013]
Furthermore, as described above, since the MIX device 23 performs a process of selecting data having a higher dimming level from a plurality of DMX signals, an arithmetic process for necessarily comparing the levels is used. . For this reason, there is a slight delay corresponding to the arithmetic processing from when the DMX signal is input to the MIX device 23 to when the processed DMX signal is output. The delay is not a problem when using one MIX device 23, but in the case of a complex dimming system, several MIX devices 23 may be connected in series, such as concerts, etc. There is a problem that the delay cannot be ignored when the scene changes in a dizzying manner.
[0014]
The present invention has been made in view of the above-mentioned problems, and the object of the present invention is that it can be quickly constructed even in a complex light control system, and no spare equipment is generated. It is another object of the present invention to provide a dimming data processing apparatus with a small delay due to arithmetic processing.
[0015]
[Means for Solving the Problems]
In order to provide such a system, the inventors of the present application first examined why the dimming wiring system described above must use various devices. It is found that this is caused by processing, that is, all dimming level data of a plurality of lighting devices are processed as one unit, in other words, processing of the entire DMX signal, that is, all channels are processed as one unit. It was. Therefore, as a basic solution, the inventors of the present application convert a dimming signal input from each dimming console 2 for each dimming level data (Channel data) of the lighting device, as shown in FIG. Through the channel data processing apparatus 1 that performs the processing, it has been conceived that the data is output on a plurality of signal lines to which the illumination device 3 is connected.
[0016]
In other words, in order to achieve a desired dimming level in each lighting device 3, a necessary channel is selected from a plurality of DMX signals input from each dimming table 2, and stored in the selected channel. It is conceived that the dimming level data is read out, subjected to predetermined processing, and again output as one DMX signal on each signal line. It has also been conceived that the processing of the channel data processing device 1 can be set from an external device 4 that is remotely located.

On the other hand, the DMX signal output from the dimming console 2 is stored in the input data buffer 9 via the DMX input unit 8, and the channel data synthesis unit 10 refers to the setting data storage unit 7 for setting information. Based on the setting information, the plurality of channel data is read from each of the plurality of DMX data stored in the input data buffer 9, and the channel data is synthesized again as one DMX data. Output to the output data buffer 11. The data stored in the output data buffer is output as a DMX signal from the DMX output unit 12 onto a signal line to which the illumination device 3 is connected.
[0043]
The above data processing will be described in detail as follows. Here, as an example, the DMX signal channels 1 to 200 input from the input terminal (1) and the DMX signal channels 201 to 512 input from the input terminal (2) are combined and output from the output terminal (6). The case where it is made to be described is specifically described. First, when the channel data synthesizing unit 10 refers to the setting data storage unit 7 and grasps the above setting, the buffer corresponding to the input terminals {circle around (1)} and {circle around (2)} in the input data buffer 9 based on the setting. With reference to 9a and b, data corresponding to Channels 1 to 200 is read from the buffer 9a, and data corresponding to Channels 201 to 512 is read from the buffer 9b.
[0044]
Next, the channel data synthesizing unit 10 synthesizes both the channel data read from the buffers 9a and 9b, creates data of Channels 1 to 512, and outputs the data to the buffer 11b in the output data buffer 11 according to the setting information. The desired DMX signal is output from the output terminal (6) of the DMX output unit 12. As described above, the data synthesis process is performed for each channel, and the DMX signal output from the DMX output unit 12 is output to the lighting device 3, while being output to the data communication unit 5 and to the external device 4. It is possible to confirm whether or not a desired operation has been performed in the channel data processing apparatus 1. In addition, the channel data synthesis unit 10 of the present embodiment can perform operations between input DMX signals, and can perform arbitrary processing expressions such as addition / subtraction and multiplication / division between selected predetermined channel data. It is possible to perform an operation by
[0045]
By the way, the channel data processing apparatus 1 performs the following operations in addition to the data processing described above. More specifically, the setting data storage unit 7 outputs the stored setting information to the visualization unit 13, and the visualization unit 13 includes the channel data processing device 1 and its input / output terminals as shown in FIG. In addition, the input terminals (1) to (4) are colored, and the output terminals (5) to (8) are colored according to the processing in the channel data processing apparatus 1. Video information is created. For example, to explain a part of the figure, the DMX signal input from the input terminal (2) (blue) is output from the output terminal (5) (blue), and the input terminal (1) (red) and The DMX signal input from (3) (green) is synthesized and expressed as a red and green stripe pattern at the output terminal (6).
[0046]
Therefore, the user of the dimming data processing apparatus according to the present embodiment compares which color on the input side and the color on the output side so that the DMX signal input to the channel data processing apparatus 1 can be transmitted from any output terminal. It is possible to grasp at a glance whether the processing has been performed. These visualization processes are realized by creating the above-described data such as HTML, and the data is output to the external device 4 via the data communication unit 5, and the display means (see FIG. (Not shown).
[0047]
The channel data processing apparatus 1 also performs an operation for confirming whether the setting has been performed normally. For example, if you want to synthesize DMX signal channels 1 to 200 input from input terminal (1) and DMX signal channels 201 to 512 input from input terminal (2), the range of both channels is set correctly. If not, a normal DMX signal cannot be created. To give a specific example, Channels 210 to 512 are erroneously set even though Channels 201 to 512 must be set as the range of the Channel of the DMX signal input from the input terminal (2). Is the case.
[0048]
The unset channel detection unit 14 refers to the set data storage unit 7 to detect whether or not there is such an error. If there is an unset channel, the channel number is output to the abnormality notification unit 15. Then, the abnormality notification unit 15 alerts the display unit with an LED or the like and outputs a signal to that effect to the visualization unit 13. The visualization unit 13 creates HTML data such as blinking with a BLINK tag for an unset channel, outputs the HTML data to the external device 4 via the data communication unit 5, and displays the display unit (not shown) of the external device 4. Z), an unset channel can be grasped.

In addition, about the structure similar to the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 4, the channel data processing unit 1 of the present embodiment, in addition to the configuration of the above-described embodiment, receives channel data for synthesis (control data) from the external device 4 via the data communication unit 5 and the setting unit 6. A data storage unit 16 for storing the data, and an existing data combining unit 17 for combining the data in the storage unit with the channel data combined by the channel data combining unit 10. I have.
[0050]
(System operation)
Next, based on the system configuration described above, the operation of the channel data processing apparatus 1 of the present embodiment will be described in detail with reference to FIGS. 1 and 4. Note that description of operations similar to those of the above-described embodiment will be omitted or simplified. First, when the external device 4 synthesizes data for each channel of the DMX signal and designates the output terminal of the DMX output unit 12 for outputting the processed DMX data, the setting information is stored in the data communication unit 5. Is output to the setting unit 6 via the control unit 6 and stored in the setting data storage unit 7 via the setting unit 6. When the setting unit 6 performs the above setting, the setting is reflected in the data stored in the data storage unit 7. When channel data (compositing data) is input by the external device 4 or the setting unit 6, the data is stored in the combining data storage unit 16.
[0051]
On the other hand, the DMX signal output from the dimming console 2 is stored in the input data buffer 9 via the DMX input unit 8, and the channel data synthesis unit 10 refers to the setting data storage unit 7 for setting information. Based on the read setting information, the plurality of channel data is read from each of the plurality of DMX data stored in the input data buffer 9 to synthesize the channel data and output to the existing data composition unit 17. . The existing data combining unit 17 reads the data stored in the combining data storage unit 16, combines it with the channel data input from the channel data combining unit 1, and outputs the combined data to the output data buffer 11. The DMX data stored in the output data buffer is output as a DMX signal from the DMX output unit 12 onto a signal line to which the illumination device 3 is connected.
[0052]
The above data processing will be described in detail as follows. Here, as an example, Channels 1 to 200 of the DMX signal input from the input terminal (1) and Channels 201 to 512 of the DMX signal input from the input terminal (2) are combined, and Channel 100 of the combined DMX signal is combined. ˜300 will be specifically described in the case where the data is output from the output terminal {circle over (7)} in place of the other channel data stored in the composition data storage unit 16. First, the channel data synthesis unit 10 creates data of Channels 1 to 512 in the same manner as in the above-described embodiment, and outputs the data to the existing data synthesis unit 17 according to the setting information. The existing data synthesizing unit 17 refers to the synthesizing data storage unit 16, replaces the channel data of the channels 100 to 300 out of the data of the channels 1 to 512, outputs the channel data to the buffer 11 c in the output data buffer 11, and DMX A desired DMX signal is output from the output terminal (7) of the output unit 12.
[0053]
FIG. 5 conceptually shows this data synthesis. Among the data input to the existing data synthesis unit 17, data previously defined in the synthesis data storage unit 16 by the external device 4 or the setting unit 6. Is output from the output data buffer 11 in place of the data. For example, as shown in the figure, the data (1) of the existing data synthesizing unit 17 is synthesized with the data (2) stored in the synthesizing data storage unit 16, and the latter half part defined in the data (2) Is replaced with data stored in the output data buffer 11 as data {circle over (3)}. Similarly, in the data (4) of the existing data synthesizing unit 17, the intermediate part is synthesized with undefined data (5) and stored in the output data buffer 11 as data (6).
[0054]
That is, as shown in these examples, the data arbitrarily defined by the external device 4 is replaced with a part of the data input to the existing data synthesizing unit 17, and the replaced data and the unreplaced data are replaced. And are to be synthesized. Instead of replacing some data, as shown in FIG. 6, the data (1) of the existing data synthesizing unit 17 is replaced with the data (2) stored in the synthesizing data storage unit 16, and the data (2) may be stored in the output data buffer 11 as it is. This is effective when the lighting device 3 is tested regardless of the input DMX signal. Further, instead of simply replacing data, dimming correction data may be stored in the synthesizing data storage unit 16 to perform arithmetic processing with the data input to the existing data synthesizing unit 17.
[0055]
For example, when the dimming level of Channel 1 is “3”, the dimming level can be set to “1” or “5” by adding or subtracting the dimming level “2” as correction data. The dimming of the desired lighting device 3 can be intentionally corrected. As described above, after the data is synthesized for each channel, the data is synthesized with the existing data, and the DMX signal output from the DMX output unit 12 is output to the lighting device 3 and to the data communication unit 5. It is output to the external device 4 and it can be confirmed whether or not the channel data processing device 1 has performed a desired operation.

Thus, it can be confirmed whether or not the channel data processing apparatus 1 has performed a desired operation.
[0061]
In addition, the unset channel detection unit 14 of the present embodiment detects whether the designation of the channel data for performing the highest processing is properly performed. For example, when the Channels 1 to 200 of the input terminals (1) and (2) are to be compared, a normal DMX signal cannot be created unless the ranges of both Channels are set correctly. To give a concrete example, Channel 1 to 201 is erroneously set even though Channel 1 to 201 must be set as the Channel range of the DMX signal input from the input terminal (2). Is the case. The unset channel detection unit 14 refers to the set data storage unit 7 to detect whether or not there is such an error.

The difference is that there is no setting unit 6 to perform, and there is no visualization unit 13, unset channel detection unit 14, and abnormality notification unit 15.
[0076]
By the way, communication between the control unit 1a and each output unit 1n is performed according to HDLC as described above, and the packet format shown in FIG. The format will be described in detail. As shown in the figure, the address A for storing the identifier of the control unit 1a or each output unit 1n, and the information communicated between the control unit 1a and each output unit 1n.

[0077]
A flag indicating the start and end of data is added before and after the format, and a frame check sequence for confirming whether the data has been normally transmitted is an information field I._nAlthough not shown, it is added after.
[0078]
(System operation)
Next, based on the above system configuration and packet format, the operation of the dimming data processing apparatus of this embodiment will be described in detail. Note that description of operations similar to those of the above-described embodiment will be omitted. First, the control unit 1a performs call-point polling for each output unit 1n, outputs a connection status request every predetermined time, and confirms the operation status of each output unit 1n. Specifically, as shown in FIG. 12B, the identifier of each output unit 1n is designated as an address A, data STAT_REQ indicating a connection status request is stored in type T, and a predetermined sequence is stored. Number S_nAnd size D_SInformation field I_nStores an ID list for writing the presence / absence of operation of each output unit, and sequentially transmits the output unit to each output unit.
[0079]
The ID list is storage areas ID1 to IDn individually assigned to each output unit 1n. For example, “1” is operating and “0” is stopped in each of the storage areas ID1 to IDn. 1-bit data is stored. Each output unit 1n that receives the connection status request determines whether the address A is its own identifier, and if it is its own identifier, the identifier of the control unit 1a is set to the address as shown in FIG. A is specified, and data STAT_RES indicating connection status response is stored in type T, and the same sequence number S as the connection status request is stored._nAnd size D_SInformation field I_nStores an ID list indicating its own operation status and a status, and returns them to the control unit 1a.
[0080]
More specifically, the ID list stores “1” in its own storage area when it is in operation, while it stores “0” when it is stopped, and the status is only for operation and stop. Instead, a more detailed operation status is stored. Next, when data processing in each output unit 1n is set from the external device 4 to the control unit 1a, the setting information is stored in the unit setting data storage unit 7a shown in FIG. The control unit 20a of the control unit 1a refers to the unit setting data storage unit 7a, and the DMX signal input from the input terminals (1) to (5) is sent to any of the output terminals (6) to (9). Check the input signal selection to see if it is set to output.
[0081]
The control unit 20 a first reads data from the input data buffer 9 and outputs the data to the data duplication unit 19. The data duplicating unit 19 duplicates the data received from the control unit 20a and outputs it to the control unit 20a. The control unit 20a outputs the data to the output data buffer 11, and a desired DMX signal is output from the DMX output unit 12. Is output. On the other hand, the control unit 20a of the control unit 1a refers to the unit setting data storage unit 7a to determine which output unit among the output units 1n is set, and compares the output unit 1b with the target output unit 1b. Determine whether ~ 1g ... is operating.
[0082]
As a result, when the target output units 1b to 1g... Are not operating, a signal to that effect is transmitted to the external device 4 via the data communication unit 5a. On the other hand, when the target output units 1b to 1g... Are operating, the unit setting data storage unit 7a is referred to and individual control commands are created for the target output units 1b to 1g. Output to the output units 1b to 1g. Specifically, as shown in FIG. 13A, the identifier of the target output units 1b to 1g... Is specified as the address A, the data SET_REQ indicating that the information setting request is stored in the type T, and Predetermined sequence number S_nAnd size D_SAnd the data ID indicating the control command and the write data as the command content are respectively set in the information field I._nAnd transmit to each output unit.
[0083]
Each output unit 1n that has received the information setting request determines whether the address A is its own identifier. If it is its own identifier, as shown in FIG. 13B, the output unit 1n uses the identifier of the control unit 1a as the address. The data SET_RES indicating that it is an information setting response is stored in the type T, and the same sequence number S as the information setting request is stored._nAnd size D_SInformation field I_nIs stored with the data ID indicating that it is a control command and the setting result, and is returned to the control unit 1a.
