Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a storage light control device for performing lighting effects on stages, studios, and the like.

BACKGROUND ART In stages, studios, and the like, a plurality of lighting loads are provided in order to obtain desired lighting effects, and the dimming levels of the plurality of lighting loads are centrally controlled in a dimming control room.

In recent dimming control, dimming data such as the dimming level of each lighting load for each scene to be produced and the time required for scene transition (fade) is stored in advance in a storage device, and the dimming data is stored in advance in a storage device. A storage dimming device is used, which is configured to sequentially reproduce the dimming levels stored in the storage device by giving an instruction each time the dimming level is stored in the storage device. In such a storage dimming device, scenes corresponding to dimming data stored in advance are assigned scene numbers in the order of playback, and the lighting effects of the scenes to be stored are stored in the storage device in the order of the scene numbers. is realized. However, among the scenes stored in the storage device, there are cases where the scenes are similar, and therefore similar lighting effects are to be performed. In such a case, inputting all the dimming data for each scene into the storage device requires a lot of effort. Taking these into consideration, storage dimming devices that are capable of repeatedly recalling the same scene number have recently come into use.

A typical prior art is shown in FIG.

The storage light control device 1 is a device for obtaining a desired lighting effect by controlling the individual light control levels of a plurality of lighting loads 2 provided on a stage, a studio, or the like. The storage light control device 1 is provided with a gene storage section 3 that stores light control data such as the light control level and the time required for fading of the lighting load 2 in 11 scenes, for example.

The scenes produced by the memory light control device 1 have scene numbers, for example, 1, 2, 3, etc. . . . are labeled as n. Correspondingly, the scene storage unit 3 stores dimming data di, d2. d3. −． dn is stored in advance.

By sequentially reproducing such dimming data d1 to dn, a desired lighting effect in each scene can be obtained.

The operation unit 4 of the storage light control device 1 includes a start button 5 that is operated each time the screen is changed in order to sequentially reproduce the light control data d1 to drr stored in the scene storage unit 3.
is provided. Further, the operation unit 4 is provided with a jump button 6 for instructing reproduction of a scene to which a certain predetermined scene number (hereinafter referred to as a jump number) is attached. The jump number is input into the jump number storage section 7 in advance.

The output of the start button 5 of the operation unit 4 is given to a counter 8. The count value of the counter 8 increases by one each time the start button 5 is operated. Further, when the jump button 6 is operated, the jump number stored in the jump number storage section 7 is set in the counter 8 as its count value.

The output of the counter 8 is given to a decoder 9, and the decoder 9 stores the scene when the count value of the counter 8 is k (where k is an integer and 1≦ and ≦rl). The dimming data dk in the section 3 is selected, and the selected dimming data dk is supplied to the fade calculating section 10.

The output of the fade calculation section 10 is given to a dimmer 11 including a triac and the like.

The lighting load 2 is connected to the dimmer 11, and the fade calculation unit 10 controls the dimming level of the lighting load 2 by controlling the firing angle of the triac of the dimmer 11, for example. Is going.

In the first operation of the operation unit 4, press the start button 5.
When is operated, the count value of counter 8 becomes "1",
Therefore, the fade calculation section 10 includes a scene storage section 13.
The dimming data d1 is given from. In this way, the lighting load 2 corresponding to scene number 1 is controlled. When the start button 5 is operated in the second operation of the operation section 4, the dimming data d2 is given to the fade calculation section 10, and thereby the lighting effect corresponding to scene number 2 is performed. Similarly, by operating the start button 5 every time the scene changes, the lighting effects corresponding to the scene numbers 1 to rl can be sequentially performed.

In a scene where the jump number stored in the jump number storage section 7 is, for example, "4", the jump button 6
By this operation, the count value of the counter 8 is set to 4. As a result, the decoder 9 selects the dimming data d4 from among the dimming data stored in the scene setting section 3, and provides the dimming data d4 to the fade calculating section 10. As a result, the lighting effect corresponding to scene number 4 will be performed. That is, before the jump button 6 is operated, the lighting effect of scene number 4 is performed regardless of which scene number the lighting effect is being performed.

Jump button 6 is operated and therefore scene number 4
When a scene change is instructed by operating the start button 5 after the lighting effects have been performed, the count value of the counter 8 increases by 1 from "4" to "5". As a result, the lighting effect of scene number 5 is performed. That is,
After operating jump button 6, press start button 5.
By operating scene number 5.6. The lighting effects corresponding to... will be performed sequentially.

Table 1 shows changes in the scene numbers as described above as the operation section 4 is operated. In Table 1, the start button 5 is operated from the first to the sixth time, the jump button 6 is operated the seventh time, and the start button 5 is operated from the eighth time to the ninth time. Ru1! : Changes in the scene locations of j and ez are shown.

(Margin below) Table 1 In such prior art, after the jump button 6 is operated, the scene number is changed to, for example, 5, 6, etc. ..., which is convenient when repeating a plurality of consecutive scenes. However, when a specific scene is to be inserted between scenes, such as a darkening at the end of a curtain, the dimming data for such a scene is stored in the scene storage unit 3 for the scene to be inserted. It must be stored between the dimming data and sequentially reproduced by operating the start button.

Therefore, if one specific scene is to be played back multiple times, it is necessary to store the same dimming data in the scene storage unit 3 for the number of times the scene is played back, which is unnecessarily time-consuming.

OBJECT An object of the present invention is to provide a storage light control device that can insert light control modes in a specific order between any order of light control modes arranged in chronological order.

Embodiment FIG. 1 is a block diagram showing the basic configuration of a storage dimming device 21 which is an embodiment of the present invention.

The storage light control device 21 controls the light control level of a plurality of lighting loads 22 installed in a studio, a stage, or the like.

The storage light control device 21 is provided with a scene storage section 23, and prior to dimming control of the lighting load 22, scene numbers 1, 2, 3, . ..., N
Corresponding to the dimming data Di, D2, D3 . ...,D
N is input.

Selection of the scene number is performed on the operation unit 24. The operation unit 24 includes a start button 25 which is an order playback means for sequentially performing lighting effects in the order of scene numbers, and a predetermined specific scene number (hereinafter referred to as jump number) α (Dadashi, α). is an integer, 1≦α
≦N) A jump button 26 is provided as an interlaced playback instruction means for performing a lighting effect corresponding to (≦N). The jump number α is input in advance to the jump number storage section 27, which is a specific order storage means.

By operating the start button 25, the scene number is changed to 1,
2,3. You can select sequentially like...
Furthermore, by operating the jump button 26, the scene number α can be selected. Further, as will be described later, when the start button 25 is operated after scene number α is selected by operating the jump button 26, the next scene of the scene number selected before the jump button 26 is operated. A number is selected.

Selection of the scene number as described above is performed in the scene control section 28. The scene control unit 28 gives a signal corresponding to the selected scene number to the decoder 29, and the decoder 29 outputs a signal corresponding to the selected scene number, for example, when the selected scene number is K (K
is an integer and 1≦≦N), the dimming data DK of the scene storage section 23 is selected and given to the fade calculation section 30. The fade calculation unit 30 controls a dimmer 31 including, for example, a triac. The dimmer 31 is connected to the lighting load 22, and therefore, when the fade calculation section 30 controls the dimmer 31, the dimming level of the lighting load 22 is controlled. The fade calculation unit 30 adjusts the dimming level of the lighting load 22 to a desired level by controlling, for example, the firing angle of the triac of the dimmer 31 based on the dimming data DK provided from the scene storage unit 23. Control to light level.

Output signals from the start button 25 and jump button 26 of the operation section 24 are given to the control section 32 of the scene control section 28. The control unit 32 is connected to a latch circuit 33 whose output is provided to a decoder 29 .

A latch signal RE is applied via a line 34, and a reset signal R3, T1 is applied via a line 35 when the storage dimmer 21 is powered on. The latch circuit 33 includes
The output terminal To of the switch 36 is connected, and the switch 36 is provided with an input terminal TS and an input terminal TJ. The switching operation of the switching device 36 is controlled by a control signal S given from the control section 32.

The input terminal TS of the switch 36 is supplied with the output of the adder ADS, and the input terminal TJ is supplied with the output of the adder ADJ. Therefore, by the switching operation in the switch 36, the value latched by the latch circuit 33 is changed to the value latched by the adder AD.
It will be switched between the output of S and the output of adder ADJ.

The output of the latch circuit 33 is connected to the adder ADS via the line 37.
, and the output of the constant setting section 38 is also provided. In the constant setting section 38, for example, "
1" is set. The adder ADS is further supplied with the output of a start buffer 39, which will be described later. The value that the adder ADS gives to the input terminal TS of the switch 36 is:
1+i+ by the value i latched in the latch circuit 33 and the value sb held in the start buffer 39
Sb...(1) is represented. In the first equation above, "1" in the first term is a constant [1] set in the constant setting section 38. The adder ADS
, a constant setting section 38, and the like constitute an order specifying means.

The start buffer 39 is connected to a line 40 from the control section 32.
An output enable signal OEI is applied via a line 41, and a reset signal R3T2 for erasing the contents held in the start buffer 39 is applied via a line 41. The value sb held by the start buffer 39 is kept at "0" unless the jump button 26 is operated, as will be described later.

The output of latch circuit 33 is connected to adder A via line 42.
It is also applied to a subtracter 43 to which the outputs of the DJ and jump number storage section 27 are applied.

The jump number storage unit 27 stores the jump number α as described above, and the output of the subtracter 43 is determined by the jump number α and the value i held by the latch circuit 33. 2). The output of such a subtracter 43 is given to a jump buffer 44.

The jump buffer 44 receives a line 45 from the control unit 32.
An output enable signal OE2 is provided via line 4.
A read signal WE is applied via 6. That is, the jump buffer 44 reads the output of the subtracter 43 into it each time the read signal WE is applied, and outputs the read and held value Jb when the output permission signal OE2 is applied.

The output of jump buffer 44 is applied to adder ADJ, and is also inverted in inverter circuit 47 and applied to start buffer 39 . jump buffer 44
The output of the inverting circuit 47 is -J due to the value Jb held by
It can be expressed as b.

Also, in the adder ADJ, Jb+i ・
... The calculation represented by (3) is performed, and the result of this calculation is applied to the input terminal TJ of the switch 36.

FIG. 2 is a flowchart for explaining the operation of the storage dimming device 21 having the above-described configuration.

When the power is turned on in the storage light control device 21, the contents held in the latch circuit 33 are erased by the reset signal R8Tl delivered to the line 35.

In step rrl, the control unit 32 determines whether the start button 25 has been operated.

If the start button 25 is not operated, step n
9, it is determined whether the jump button 26 has been operated. If it is determined in step rI9 that the jump button 26 is not operated, step n1
Return to

In step n1, when the start button 25 is operated, the process proceeds to step r+2, where the output permission signal OE1 is given to the start buffer 39 from the control section 32. As a result, the start buffer 39 provides the value sb held therein to the adder ADS. Note that the contents held in the start buffer 39 are set to "0" by the reset signal R3T2 given from the control section 32 immediately after the power is turned on.
” is set.

The process proceeds to step n3, where the switch 36 switches the controller 32
By the control signal S given from the output terminal To
is connected to the input terminal TS. Next, in step n4, the latch circuit 33 receives the latch signal RE from the control section 32.
is given, and as a result, in the latch circuit 33, the adder A
The output of DS is latched.

, in step rr5, the jump buffer 44
A read signal WE is applied from the control section 32 to write the output of the subtracter 43 into the jump buffer 44.

Next, in step n6, the output of the output permission signal OEI from the control unit 32 to the start buffer 39 is stopped;
As a result, the adder ADS has a start buffer 39
output will no longer be given.

The post-processing proceeds to step n7, where a reset signal R8T2 is applied to the start buffer 39 to reset its held contents. Subsequently, in step n8, the control unit 32 stops outputting the read signal WE to the jump buffer 44, thereby stopping writing of the output of the subtracter 43 to the jump buffer 44.

This post-processing returns to step n1.

The power is turned on to the memory dimmer device 21 and the start button 2 is pressed.
5 is operated, the value sb held by the start buffer 39 at this time is [OJ, so in the latch circuit 33,
The value i to be latched is set to "1". As a result, the decoder 29 selects the dimming data DI from among the dimming data stored in the scene storage section 23 and supplies it to the fade calculation section 30 .

As a result, the lighting load 22 is set to the dimming level corresponding to scene number 1.

At this time, the subtracter 43 is given the output of the latch circuit 33 via the line 42, so that the value Jb read by the jump buffer 44 is Jb-α-1...(
4) It becomes.

Next, when the start buffer 25 is operated for the second time,
The value output by the adder ADS is "2", that is, the value output by the start buffer 39 is "0", and the value latched by the latch circuit 33 is "1".
In the adder ADS, the constant "1" given from the constant setting section 38 is added to the value "IJ" latched by the latch circuit 33, and the output value becomes "21." After this, the latch circuit When the latch signal RE is given to 33,
The latch circuit 33 retains the value "2", which causes the decoder 29 to select the dimming data D2 stored in the scene storage section 23.

As a result, dimming control of the lighting load 22 corresponding to scene number 2 is performed.

Similarly, for example, when the start button 25 is operated twice, the value latched in the latch circuit 33 becomes K, and at this time the decoder 29 selects the dimming data DK,
As a result, dimming control of the lighting load 22 corresponding to the scene number K is performed.

At this time, the jump buffer 44 stores the value J
b is (α-K).

In FIG. 2, when it is determined at step n1 that the start button 25 has not been operated, and when the control unit 32 detects that the jump button 26 has been operated at step n9, the process proceeds to step nlo. In step nlo, the output enable signal OE2 is applied from the control section 32 to the jump buffer 44 via the line 45, whereby the value Jb held in the jump buffer 44 is applied to the inverting circuit 47 and the adder ADJ.

Therefore, -Jb is set in the start buffer 39 at this time.

Next, the process proceeds to step rr l l, in which the output terminal To of the switch 36 is connected to the input terminal TJ.

As a result, when the latch signal RE is then applied from the control section 32 to the latch circuit 33 in step n12, the output of the adder ADJ will be latched. Adder A
The addition result in DJ is expressed by the third equation above,
Also, since the value Jb given to the adder ADJ from the jump buffer 44 is expressed by the second equation above, the value latched by the latch circuit 33 is (α-i)+i-α...-(5). Become.

Therefore, the decoder 29 selects the dimming data Dα from among the dimming data stored in the scene storage section 23. As a result, dimming control of the lighting load 22 corresponding to the scene number α is performed.

In step n10, when the jump buffer 44 supplies the value Jb held by the inversion circuit 47, the value sb held by the start buffer 39 becomes -Jb.

For example, when the jump button 26 is operated in the (M+1)th operation of the operation unit 24, -(α-M) . . . are stored in the three start buffers.
The value expressed by (6) is given. As a result, when the output permission signal oE1 is next applied to the start buffer 39 and an addition operation is performed in the adder ADS,
The addition result is 1+i+5b=1 +α+ (-(α-M)1=1+α
−α0M=1+M (7). In other words, from this state, next press the start button 25.
When the jump button 2 is operated, the latch circuit 33 latches the value represented by (1+M).
It is possible to perform dimming control corresponding to the scene number next to the scene number before 6 is operated.

In step rr13, the output of the output permission signal OE2 to the jump buffer 44 of the control unit 32 is stopped;
As a result, jump 1 buffer 44 no longer provides its output to inverting circuit 47 and adder ADJ. Next, in step r114, the controller 32 sends the jump buffer 44
A read signal WE is applied to the jump buffer 44, thereby writing the value output from the subtracter 43 into the jump buffer 44.

Due to the latch operation of the latch circuit 33 in step n12, the value i held by the latch circuit 33 has become the jump number α, so the value output by the subtracter 43 is "0".
Therefore, the value Jb held by the jump buffer 44 becomes "0".

Next, in step n15, the control section 32 stops outputting the read signal WE, so that the value output from the subtracter 43 is no longer read into the jump buffer 44. This post-processing returns to step r11.

Values held by each unit when the jump number α stored in the jump number storage unit 27 is set to “4”, that is, when the jump button 26 is operated to perform dimming control corresponding to scene number 4. , and the selected scene number are shown in Table 2.

(Left below) 2nd table In the first operation of the operation section 24, the start button 2 is pressed.
5, the value sb held by the start buffer 39 at this time is "0", so the value i latched by the latch circuit 33 becomes "1".

As a result, the value output by the subtracter 43 becomes "3", so when the read signal WE is applied to the jump buffer 44, the value Jb held therein becomes "3".

During the period when the start button 25 is continuously operated, the output of the jump buffer 44 is transferred to the inverting circuit 4.
7 and the adder ADJ, the value Sb held by the start buffer 39 remains "0" and does not change.

In the third operation of the operation unit 24, press the jump button 2.
5 is operated, the output permission signal OE2 is given to the jump buffer 44, so the value "2" held by the jump buffer 44 at the time of the second operation is inverted and the value "-2" is stored in the start buffer 39. " is set.

At this time, the addition result of the adder ADJ becomes the value held in the jump number storage section 27, so the value is r4. becomes.

When the start button 25 is operated in the fourth operation of the operation unit 24, the latch circuit 33 latches the value i.
becomes r3 (=1+4-2)J.

The value held by the start buffer 39 at this time.

It is reset to "0" and the jump buffer 4
The value Jb held by 4 is rl(=4-3)J.

Thereafter, the operation of the operation unit 24 is performed one-by-one in the same manner. The scene numbers selected at this time are also shown in Table 2. As shown in Table 2, the lighting effect corresponding to scene number 4 can be inserted at a desired position between scenes by operating the jump button 26.

As described above, in this embodiment, the start button 25
When performing the following operations consecutively, the start buffer 39
The value sb held in the latch circuit 33 is set to "0", and the latch circuit 33 increases the latch value i by "1" each time the latch signal RE is applied. 23 to the fade calculation unit 30, scene numbers 1, 2, 3, . ... corresponding dimming data D1°D2. D3. . . . are given sequentially, and the lighting effects for each scene are sequentially performed. The output of the latch circuit 33 is also given to a subtracter 43, the difference from the jump number α is calculated, and this value is written into the jump buffer 44.

When the jumper 1 button 26 is operated, the switch 36
Its output terminal To is connected to the input terminal TJ. Furthermore, the value Jb held by the jump buffer 44 is added to the adder ADJ.
, the jump number α is latched in the latch circuit 33. The value Jb held by the jump buffer 44 is also inverted and transferred to the buffer 39.
given to. This will cause the start button 25 to
When is operated, the addition result in the adder ADS is the value obtained by adding "1" to the value latched in the latch circuit 33 before the jump button 26 was operated. That is, when the start button 25 is operated subsequent to the operation of the jump button 26, the scene following the scene that was played before the jump button 26 was operated will be played. This makes it possible to insert a scene corresponding to the jump number α set in the jump number storage unit between arbitrary scenes.

Effects According to the present invention as described above, dimming can be done in a chronological order! I! Aa! It is now possible to insert dimming modes in a specific order between any arbitrary order of the memory dimming device, and the operability and usability of the storage dimming device can be greatly improved.
