Description

  The present invention relates to a light control panel for turning on and off a lighting device and dimming based on a DMX signal.

  For example, for a lighting device used for lighting in a theater or a stage, the power is adjusted by a dimming panel based on a dimming signal from the dimming device, and the adjusted power is supplied to the lighting device as a load. Then, the lighting device is dimmed and controlled. Such a light control panel is usually formed by preparing a plug-in unit having a unit structure and housing a plurality of plug-in units in a rack-like case body. Each plug-in unit is equipped with a dimmer, and an illuminating device is connected to the dimmer to control the dimming of the illuminating device.

  As a dimming signal, a USITT standard DMX512, which is a kind of RS485, is generally used. The format of this DMX signal is used to store a start mark for finding the head of data and dimming level data of the lighting device. There are 512 frames, and data including 255 levels of dimming levels is stored in each of the 512 frames. Accordingly, it is possible to connect 512 dimmers per DMX signal and control the dimming level of the lighting device in 255 levels. Thus, since the DMX signal has 512 frames, the frame number of the DMX signal is set in units of dimmers in order to correspond one frame to one dimmer.

Here, the DMX signals (dimming signals) input from a plurality of dimming consoles are processed on a plurality of signal lines to which the lighting device is connected via a channel data processing device that processes each dimming level data of the lighting device. And a desired dimming level can be realized in each lighting device (for example, see Patent Document 1). In this Patent Document 1, dimming level data stored in the selected channel (frame) is selected from a plurality of DMX signals input from the dimming consoles. Are respectively read out, subjected to predetermined processing, and again output as one DMX signal on each signal line.

  However, even in the case of Patent Document 1, when one frame of a DMX signal is associated with one dimmer, an address for a transmission signal is set for each dimmer and a frame number of the DMX signal is set. Therefore, when the number of dimmers to be used increases, it takes much time to set addresses (frame settings) for transmission signals of the dimmers.

  The number of dimmers used in one dimming panel is large and may exceed 1000. Therefore, when a frame number is set for each dimmer, the frame number is used when manufacturing the dimming panel. There is a lot of trouble for setting. In addition, it is necessary to set the frame number of the dimmer at the time of maintenance replacement of the dimmer panel. In addition, there is a problem that the dimming control of the lighting device cannot be performed properly if there is an incorrect mounting of a dimmer with a different frame number on the dimmer panel or an incorrect setting of the frame number on the dimmer. .

  An object of the present invention is to provide a dimming panel that can easily set the address of a dimmer and can appropriately perform dimming control using a DMX signal.

  FIG. 1 is a block diagram of a light control panel according to an embodiment of the present invention. The light control board 11 is mounted with a control unit 12 and a plurality of light adjusters 13a to 13n. The main body of the light control panel 11 is formed on a rack, and a plurality of light adjusters 13a to 13n formed as plug-in units are inserted into the main body of the light control panel 11. The control unit 12 is also formed as a plug-in unit and is inserted into the main body of the light control panel 11.

  When the dimmers 13a to 13n are inserted into the main body of the dimming board 11, they are connected to the mother board 14 by connectors not shown. The motherboard 14 outputs the area number (address) to the dimmers 13a to 13n when the dimmers 13a to 13n are inserted, and supplies control power to the dimmers 13a to 13n. In addition, lighting devices 23a to 23n are connected to the light adjusters 13a to 13n, and power to the lighting devices 23a to 23n is also supplied from the light control panel 11 to the lighting devices 23a to 23n.

  A DMX signal is input to the control unit 12 of the light control panel 11 from a DMX device 15 such as a light control console. The DMX signal from the DMX device 15 is received by the DMX receiving unit 16 and input to the data processing unit 17. On the other hand, in the storage unit 18 of the light control panel 11, the area number corresponding to the mounting position where the light control devices 13 a to 13 n are mounted, and the DMX used by the plurality of light control devices 13 a to 13 n in the main body of the light control panel 11. The leading number of the DMX frame included in the signal is stored in advance.

  The data processing unit 17 allocates DMX frames received from the outside to the dimmers having addresses corresponding to the area numbers based on the head number and the area number stored in the storage unit 18, and passes through the DMX transmission unit 19. Then, a DMX signal (DMX frame) is transmitted.

  The operation panel 20 stores the area number in which the dimmers 13a to 13n are mounted and the head number of the DMX frame included in the DMX signal used by the dimmers 13a to 13n via the data processing unit 17. 18 is set and input. In addition, a data receiving unit 21 is provided. The data receiving unit 21 receives the area number and the leading number transmitted from the external setting device 22 such as a general-purpose PC, and the data receiving unit 21 receives the area number and the leading number. It is configured so that it can be memorized.

  FIG. 2 is an explanatory diagram of allocation of area numbers of mounting positions in which the dimmers 13a to 13n of the main body of the dimmer 11 are accommodated. FIG. 2 shows a case where 15 areas are allocated. The area number divides the mounting area of the dimmer 13 of the dimmer 11 at equal intervals, and assigns a number to each of them. Since the dimmers 13a to 13n differ in size depending on the load of the lighting device, the mounting area is allocated in accordance with the smallest dimmer 13.

  If the load subject to dimming control is up to 2 kW, control is possible with the minimum dimmer. On the other hand, if the load of the dimming control target is larger than 2 kW, a dimmer larger than the smallest dimmer is used, and one dimmer requires a plurality of areas (mounting space). Become.

  FIG. 3 is an explanatory diagram when 10 dimmers 13 a to 13 j are mounted on the main body of the dimmer 11. Seven dimmers 13a to 13c and 13g to 13j are the smallest dimmers, and dimmers 13d and 13e are dimmers having a size corresponding to three of the smallest dimmers. The device 13f is a dimmer having a size corresponding to three of the smallest dimmers.

  When the smallest dimmers 13a to 13c and 13g to 13j are inserted into the main body of the dimmer panel 11, the mother board 14 is an area where the dimmers 13a to 13c and 13g to 13j are inserted into the main body of the dimmer panel 11, respectively. The number is output to each of the dimmers 13a to 13c and 13g to 13j. The dimmer 13a has area number 1, the dimmer 13b has area number 2, the dimmer 13c has area number 3, the dimmer 13g has area number 12, the dimmer 13h has area number 13, The area number 14 is output to the dimmer 13i, and the area number 15 is output to the dimmer 13j.

  The dimmer 13d is a dimmer having a size corresponding to three of the smallest dimmers and occupies three areas of area numbers 4, 5, and 6, but the dimmer 13d is a dimmer panel. 11 is inserted into the main body 11, the mother board 14 outputs the head area number 4 of the area numbers 4, 5, 6 to the dimmer 13 d. Similarly, when the dimmer 13e is inserted into the main body of the dimmer board 11, the mother board 14 outputs the first area number 7 of the area numbers 7, 8, and 9 to the dimmer 13e.

  The dimmer 13f is a dimmer having a size corresponding to two of the smallest dimmers, and occupies two areas of area numbers 10 and 11, but the dimmer 13f When plugged into the main body, the mother board 14 outputs the head area number 10 of the area numbers 10 and 11 to the dimmer 13f.

  Thus, the mother board 14 indicates in which area the dimmer 13 is mounted by an area number. When the dimmer 13 occupies a plurality of areas, the area number of the dimmer 13 is The area number that is exclusively used is the smallest number. Thereby, the light adjusters 13a to 13j automatically recognize the mounting position (its own area number) on the light control panel 11.

  Next, the area numbers of the light adjusters 13 a to 13 j mounted on the main body of the light control panel 11 are set and input to the control unit 12 and stored in the storage unit 18 in advance. The setting input of the area numbers of the dimmers 13 a to 13 j to the control unit 12 is performed from the operation panel 20 or the external setting device 22. In addition to the setting input of the area number, the leading number of the DMX frame included in the DMX signal used by the dimmers 13 a to 13 j in the main body of the dimming board 11 is also set and inputted and stored in the storage unit 18.

  FIG. 4 is an explanatory diagram of processing contents for allocating the DMX frame of the DMX signal to each lighting device in the control unit 12. When receiving the DMX signal, the control unit 12 refers to the head number stored in the storage unit 18, and designates the DMX frame indicated by the head number as the first frame of the DMX signal to be transmitted to the dimmers 13a to 13j. Receive DMX data (DMX frame sequence) for the mounting area is captured.

  FIG. 4 shows a case where the leading number of the DMX frame of the DMX signal used in the dimmers 13a to 13j is 5. When the data processing device 17 of the control unit 12 receives the DMX signal from the DMX device 15 via the DMX receiving unit 16, the data of the dimmers 13a to 13j is read from the DMX frame 5 having the head number 5 stored in the storage unit 18. The number (10) of DMX frames 5 to 14 is taken. Then, the imported DMX data (DMX frames 5 to 14) are assigned in order from the smallest area number. As shown in FIG. 3, the area numbers are ten area numbers 1 to 4, 7, 10, and 12 to 15. That is, the data processing unit 17 sequentially assigns the DMX frames 5 to 14 to the area numbers 1 to 4, 7, 10, 12 to 15 and transmits them to the dimmers 13a to 13j.

  DMX frame 5 to dimmer 13a of area number 1 is transmitted in transmission frame 1, DMX frame 6 to dimmer 13b of area number 2 is transmitted to transmission frame 2, and dimming frame 6 of area number 3 is transmitted to transmission frame 3. The DMX frame 7 to the optical device 13c is allocated, and the DMX frame 8 to the dimmer 13d having the area number 4 is allocated to the transmission frame 4. Since the transmission frames 5 and 6 do not have the area numbers 5 and 6, no area numbers are assigned. The dimming level is set to 0 for the transmission frames 5 and 6 to which no area number is assigned.

  Similarly, the DMX frame 9 to the dimmer 13e with the area number 7 is assigned to the transmission frame 7, and the dimming level is set to 0 because the transmission frames 8 and 9 are not assigned with an area number. The DMX frame 10 to the dimmer 13f of the area number 10 is allocated to the transmission frame 10, and the dimming level is set to 0 because the area number of the transmission frame 11 is not allocated.

  The DMX frame 11 to the dimmer 13g of the area number 12 is transmitted to the transmission frame 12, the DMX frame 12 to the dimmer 13h of the area number 13 is transmitted to the transmission frame 13, and the dimming of the area number 14 is transmitted to the transmission frame 14. The DMX frame 13 to the optical device 13i is assigned, and the DMX frame 14 to the dimmer 13j having the area number 15 is assigned to the transmission frame 15, respectively. Then, the DMX signal composed of this transmission frame is transmitted to each of the dimmers 13a to 13j.

  Each of the dimmers 13a to 13f takes in the information of the same frame number as the area number from the DMX signal received from the control unit 12, and outputs the dimming signal to the lighting device.

  In this way, the mounting area of the light control panel 11 is divided into equally spaced areas, numbers are assigned to the areas, and when the light control device 13 is mounted on the main body of the light control panel 11, the light control device 13 has the area number. Is automatically recognized. On the other hand, the control unit 12 stores in advance the mounting position (area number) of the dimmer 13 and the leading number of the DMX frame used in the dimming board 11, and the received DMX signal is stored in the leading number and dimming. Allocate according to the area number of the device 13 and transmit to the dimmer 13 by the DMX signal. The dimmer 13 receives the DMX signal from the control unit 12 and dimmes the lighting device at the dimming level corresponding to the area number.

  Therefore, even when the dimmer 13 of less than a predetermined number is mounted on the main body of the dimmer 11 and there is an empty area of the dimmer 13, the DXM frame is output to the empty area of the dimmer 13. There is nothing. Thereby, less than a predetermined number of dimmers can be mounted on the main body of the dimmer 11.

  That is, just by inserting the dimmer 13 into the main body of the dimmer 11, the dimmer 13 recognizes the area number, so even if the number of dimmers 13 mounted on the main body of the dimmer 11 is less than a predetermined number, Application to different illumination systems is possible only by changing the insertion of the dimmer 13 into the main body of the dimmer 11. In that case, the area number of the dimmer 13 whose insertion into the main body of the dimmer 11 and the leading number of the DMX frame used in the dimmer 11 are set and input to the control unit 12 by the operation panel 20 or the external setting device 22. Then, the changed content is stored in the storage unit 18. Thereby, application to a different illumination system can be performed easily.

  In addition, by transmitting the DMX signal from the control unit 12 to the dimmer, it is possible to use a dimmer having a DMX signal processing function that has been used in the past. Versatility can be improved.

  According to the embodiment of the present invention, the address setting of the dimmer 13 can be set not in units of dimmer but in units of the dimming panel 11, so that it is possible to easily set the DXM frame to the dimmer 13. In addition, the area number and the head number can be easily changed by the operation panel 20 or the external setting device 22, and the contents can be visually checked by a display device. It is.
