Abstract

recorder for DMX-512 Signals, wherein a DMX-512 light control element (204) by the specified channels of the DMX-512 controller (101) recording the recording element (203) can control and interrupt.

Description

Technical area

The The invention relates to a recorder for DMX-512 signals, by the specified channels the DMX-512 controller controls the recording of the DMX-512 signals.

State of the art

DMX-512 is a standard for Lighting control. about 90% of the world's lighting control systems use the DMX-512 standard. However, a DMX-512 Coltroller is expensive for some applications.

Therefore an open-type system was developed, whereby the recorder and the DMX-512 controller operated separately become.

at of the recording however, some of the data is lost (the recorder is later accessed as the DMX controller) or blank data is recorded (the recorder is controlled earlier as the DMX controller).

Object of the invention

Of the Invention is based on the object, a recorder for DMX-512 To create signals that can overcome the disadvantages of the conventional solution.

Ways to execute the invention

DMX-512 is a digital control protocol used in stage and show control technology Dimmers, intelligent headlamps and effect devices applied becomes.

1 shows a DMX-512 controller consisting of a microprocessor ( 101 ), a DMX input interface ( 102 ), a DMX output interface ( 103 ), a memory ( 104 ), an input unit ( 105 ), which contains a keyboard or switch, and an output unit ( 106 ) containing indicator lights. The memory may be a flash memory or a random access memory (RAM, DRAM) or a memory card. The DMX input interface ( 102 ) and the DMX output interface ( 103 ) are standardized RS-485 interface. All components of the recorder are commercially available.

Like from the 2 and 3 can be seen, the DMX-512 controller can connect up to 512 channels per connection ( 202a - 202z ) (Channel CH1-CH512) with a resolution of 8 bits, taking the values from 0-255. The recording element ( 203 ) can receive data from the corresponding channels according to its address ( 202a - 202z ) access. A small system usually does not use all 512 channels.

Therefore, the DMX-512 transmits light control ( 204 ) the corresponding data for recording through the last channels ( 202x . 202y . 202z ). If the recording element ( 203 ) the data in the channels ( 202x . 202y . 202z ), it performs a corresponding action. Therefore, the user only needs to operate the DMX-512 controller, so that the recording is simplified.

• 1. Der Datenwert "0" des letzten Kanals (202z) wird als Preset der Aufzeichnung angenommen (301). Dabei startet das Aufzeichnungselement (203) entsprechend der angegebenen Aufzeichnungsdatenanzahl (302) und Aufzeichnungsadresse (303) die Aufzeichnung (304), wenn der Datenwert des letzten Kanals (202z) (CH512) unglich 0 ist. Wenn der Datenwert des letzten Kanals (202z) (CH512) auf 0 zurückgesetzt wird, wird die Aufzeichnung unterbrochen (305). Hierbei kann der letzte Kanal auch durch einen anderen Kanal ersetzt werden.
• 2. Der Datenwert des letzten Kanals (202z) wird weiterhin als die gültige Anzahl der Kanäle (202a, 202b...) des Signals aus dem DMX-512 Lichtsteuerelement (204) angenommen. Hierbei kann der letzte Kanal auch durch einen anderen Kanal ersetzt werden.
• 3. Die angegebene Aufzeichnungsdatenanzahl (302) ergibt sich mit der Formel N = (CH512)·K, wobei K eine beliebige Zahl sein kann. Da die Übertragungsdaten maxiamal 512 Byte enthält und die Daten eines Kanals auf den Wert 0–255 gesetzt werden können, kann ein K-Wert definiert werden.
• 4. Der Datenwert des vorletzten Kanals (202y) wird als die Ausgangsdaten aus dem DMX-512 Lichtsteuerelement (204) angenommen, die in dem Aufzeichnungselement (203) gespeichert werden (das Aufzeichnungselement (203) kann mehrere Lichtprogramme aufzeichnen) Hierbei kann der vorletzte Kanal auch durch einen anderen Kanal ersetzt werden.
• 5. Beim Editieren des Lichtprogramms durch das DMX-512 Lichtsteuerelement (204) kann vor dem Beginn des Lichtprogramms eine Pause eingefügt werden, wobei der Datenwert des letzten Kanals (202z) auf 0 gesetzt wird. Während des Lichtprogramms wird der Datenwert des letzten Kanals (202z) ungleich 0 gesetzt. Nach dem Lichtprogramm wird der Datenwert des letzten Kanals (202z) wieder auf 0 gesetzt.
• 6. Nach dem Editieren des Lichtprogramms und der Verbindung des Aufzeichnungselementes (203) und des DMX-512 Lichtsteuerelementes (204) kann das Aufzeichnungsele ment (203) entsprechend dem Datenwert des letzen Kanals (202z) des DMX-512 Lichtsteuerelementes (204) den Rekorder steuern, wenn das DMX-512 Lichtsteuerelement (204) das editierte Lichtprogramm wiedergibt.

4 shows a flowchart of the recording.

• 1. The data value "0" of the last channel ( 202z ) is assumed to be the preset of the recording ( 301 ). The recording element ( 203 ) according to the specified number of recorded data ( 302 ) and recording address ( 303 ) the recording ( 304 ), if the data value of the last channel ( 202z ) (CH512) is not 0. If the data value of the last channel ( 202z ) (CH512) is reset to 0, the recording is interrupted ( 305 ). In this case, the last channel can also be replaced by another channel.
• 2. The data value of the last channel ( 202z ) is still considered the valid number of channels ( 202a . 202b ...) of the signal from the DMX-512 light control element ( 204 ) accepted. In this case, the last channel can also be replaced by another channel.
• 3. The specified number of recordings ( 302 ) is given by the formula N = (CH512) · K, where K can be any number. Since the transmission data contains a maximum of 512 bytes and the data of a channel can be set to the value 0-255, a K value can be defined.
• 4. The data value of the penultimate channel ( 202y ) is taken as the output data from the DMX-512 light control element ( 204 ), which in the recording element ( 203 ) (the recording element ( 203 ) can record several light programs) In this case, the penultimate channel can also be replaced by another channel.
• 5. When editing the lighting program by the DMX-512 light control element ( 204 ), a pause can be inserted before the start of the light program, whereby the data value of the last channel ( 202z ) is set to 0. During the light program, the data value of the last channel ( 202z ) not equal to 0. After the light program, the data value of the last channel ( 202z ) again set to 0.
• 6. After editing the lighting program and the connection of the recording element ( 203 ) and the DMX-512 light control element ( 204 ), the recording element ( 203 ) according to the data value of the last channel ( 202z ) of the DMX-512 light control element ( 204 ) control the recorder when the DMX-512 light control ( 204 ) plays the edited light program.
