[Detailed description of the invention]

0001

[Industrial Application Field] The present invention applies a fade-in/fade-out control technology of a dimming circuit using a zero-cross timer to a plurality of lighting devices installed in a television studio or a theater, and theater equipment such as screens, curtains, and projectors. The present invention relates to a control method and a control device for controlling the drive of a motor.

2. Description of the Related Art Television studios, theaters, etc. are equipped with a large number of lighting devices, as well as theater equipment such as screens, curtains, and projectors, and air conditioners. Conventionally, the dimming and blinking control of lighting equipment and the drive control of theater equipment and air conditioning equipment have been controlled by separate control devices due to the complexity of the equipment. Therefore, for example, when a performance by a choir and symphony orchestra, play, ballet, opera, etc. starts in a theater, etc., the lights in the audience seats are first faded out, and the lights on the stage side are faded in, simultaneously or for a few seconds. After that, a series of operations such as operating theater equipment such as curtains, and then increasing the volume of the stage microphone, and at the end of the performance, the lights in the audience seats are faded in and the lights on the stage side are faded out, either at the same time or after a few seconds. A series of operations are required to operate theater equipment such as curtains. Further, the content of a performance program such as a play or a performance, or a performance program is composed of a plurality of different contents such as a first part to a fifth part.

[0003] Therefore, the above operations are frequently performed. However, as mentioned above, in the past, multiple operators operated separate control devices, such as the dimming and blinking control device for lighting equipment and the drive control device for theater equipment, under the instructions of the stage director. Overall control has tended to rely heavily on the stage director's delicate sensibilities, long experience, and keen intuition. Particularly in performances such as opera, complex lighting patterns are used to effectively enliven the singing and acting. Furthermore, when projecting a movie, various operations such as lowering and raising the screen, opening and closing curtains, turning on and off the projector, and reproducing theater scenes are required. It is extremely difficult to control the timing of lighting control for such a complex lighting pattern and drive control of theater equipment according to the content of the performing arts.

0004

[Problems to be Solved by the Invention] The present invention solves the difficulties in timing of conventional dimming and blinking control of lighting equipment and drive control of theater equipment and air conditioners by providing fade-in/fade-out control of a dimming circuit using a zero-cross timer. The present invention attempts to control the dimming and blinking of a lighting device using the technology, and to synchronize the drive control of a plurality of theater equipment by using the zero-cross timer.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an integrated control method for dimming and blinking control of lighting loads and drive control of theater equipment. Create a program table with addresses and flags set, divide the frequency half wave by 256,
Determine the number of zero-cross counts in one step, calculate the movement amount and speed of each load from the current point to the next point, and perform synchronized control of dimming and blinking control of lighting loads and drive control of theater equipment, if possible. Further, the integrated control device for dimming and blinking control of lighting loads and drive control of theater equipment according to the present invention is characterized in that the integrated control device of the present invention controls dimming and blinking of a plurality of lighting loads, a plurality of theater instruments, and the plurality of lighting loads. A central control device that controls and drives and controls the plurality of theater equipment, a total control panel that gives instructions to the central control device, and a remote control device that transmits an infrared beam to the total control panel and remotely operates it. It is characterized by

The firing angle data is counted down by the 8-bit programmable counter (Z80A CTC), and when the counter reaches zero, a zero count output signal is output from the 8-bit programmable counter (Z80A CTC). The data is latched by a semiconductor device (IC) triggered by a basic pulse to obtain a firing signal. Here, the zero-cross timer is a 16-bit increment counter that generates a zero-cross pulse at the timing when the voltage of the commercial power supply becomes zero, and increments when a zero-cross interrupt occurs.The table below shows the relationship between its frequency and time. shows.

[0007]

[Table 1]

The operating principle of fade-in/fade-out consists of a combination of setting up flags/down flags, and generating data change counter data and data counters, as described below. Each of these items will be explained below.

Setting up flags/down flags: First, the addresses and flags of a plurality of lighting loads and a plurality of theater equipment are set. To turn on the brightness of the lighting load or the movement of a plurality of theater appliances, set the up flag, and to turn off the brightness of the lighting load or the movement of theater appliances, set the down flag. The current brightness of the lighting load and the operating level of multiple theater equipment are referred to as the current brightness or operating amount, and hereinafter referred to as "actual lev".
el". In addition, the brightness of the lighting load and the operation level of multiple theater equipment set in the future, which are set in the future temporally advanced from the current brightness of the lighting load and the operation level of multiple theater equipment, can be adjusted to the brightness or operation level at the next point in time. It is called "quantity" and is written as "next level" here. As shown in FIG. 2(A), if the current level of brightness or amount of movement is smaller than the level of brightness or amount of movement at the next point in time, it is necessary to increase the level of brightness or amount of movement. . In this case the flag is set to positive.

That is, it is as follows. actual level<next level
⇒ flag="+" As shown in Figure 2 (B),
If the current level of brightness or amount of activity is greater than the level of brightness or amount of activity at the next time, it is necessary to lower the brightness or amount of activity. in this case,
The flag is set to negative. That is, it is as follows. actual level>next level
⇒ flag=”-”

Data change counter data: As shown in FIG. 3(A), data changes from zero level to full level.
Fade in (f level)
ade in), and as shown in Figure 3(B), from full level to zero level (z
ero level) is called a fade out. Furthermore, the zero level (z
from ero level to full level
vel) or full level (full le
The time from zero level to zero level is called fade time, and the relationship between the zero cross timer described above and this fade time is 5 if the fade time (FT) is constant.
At 0Hz, the time per zero crossing is 10 microseconds {1/50[Hz] ÷2} as described above, so the zero crossing timer at 50Hz (Zft
50) is the fade time divided by the time per zero crossing at 50 Hz.

That is, it is as follows. Zft50 = FT/10*10-3 For example, if 10 seconds is one zero cross time, then 10
sec/10sec*10-3=1000, that is, 50
At Hz, if you count the number of 1000 zero crosses, it will be 10 seconds, and at 60Hz, the time per zero cross is 8.3 msec as mentioned above.
1/60 [Hz] ÷ 2}, so the zero cross timer (Zft60) at 60Hz has a fade time of 6
It is divided by the time per zero crossing at 0Hz.

That is, it is as follows. Zft60 = FT/8.3sec*10-3 For example,
If 10 seconds is one zero cross time, then 10 seconds
/8.3sec*10-3 =1205, that is, 60H
At the time of z, counting the number of zero crosses of 1205 times gives 10 seconds. That is, the zero cross timer is the fade time divided by the time for one zero cross. That is, by counting the number of zero crosses, a timer function can be generated.

[0014] Furthermore, from zero level to full level, 25
When the change is made in 6 steps, the relationship between the zero cross and 256 steps is as follows, assuming that the number of zero crosses in one step is Dchg. Dchg=Zft/256

Generation of data counter: As shown in FIG. 2(A) or FIG. 2(B), the brightness level changes from the current brightness level to the next brightness level at a constant fade time. In other words, if the brightness level at the next point in time is brighter than the brightness level at the current point in time, the overall amount of movement will be the same as that at the next point in time. This is the difference obtained by subtracting the current brightness level from the brightness level. That is, if the total amount of movement is Δlevel and the number of zero-cross counts is Γ, the following equation holds true. If actual level<next level, △ level= next level − a
ctual levelZft / △ level=
Γ In other words, the amount of movement per one count is calculated as a plus. Next, if the brightness level at the next point in time is darker than the brightness level at the current point in time, the total amount of movement is the difference between the brightness level at the next point in time and the brightness level at the current point in time. be.

That is, if the total amount of movement is Δlevel and the number of zero-cross counts is Γ, the following equation holds true. If actual level>next level, next level - actual lev
el = −△ levelZft / −△ level
l=-Γ In other words, the amount of movement per one count is calculated as a negative value.

From the above, the principle of operation of the fade-in/fade-out is that, as described above, it is first determined in which direction the displacement of the flag is set based on the setting of the up flag/down flag and the data change counter data. 256 from zero level brightness to full level brightness
The number of zero-cross counts per one step is determined by dividing the number of times into steps. Therefore, if the amount of movement from the current level to the next level is solved, the amount of movement per step is calculated, and if the fade time is 1
If it is 0 seconds, the fade time of zero cross is solved,
Since the count number of zero crosses is known, the amount of movement can be determined.

That is, the following equation is obtained. Zft / Γ = △ level The dimming control of a lighting device using a zero cross counter can not only dim an incandescent lamp with a certain lighting pattern, but also extend or shorten the dimming control time. Since it is possible to do this, it is possible to adjust the timing of the time for controlling the dimming of incandescent lamps and the time for controlling blinking of fluorescent lamps. Furthermore, it has become possible to measure the number of zero crossings, that is, to use it as a timer to drive and control theater equipment such as screens, curtains, and projectors. This has made it possible to synchronize the dimming and blinking control of lighting devices and the drive control of theater equipment.

When changing the brightness of the lighting load or the amount of operation of theater equipment in a certain period of time, determine how much the brightness changes in a certain period of time or how much amount of operation should be set. By referring to the table that records the lighting pattern (cue) or operation program, the +/- of the flag is determined, and the brightness changes between the current brightness and amount of operation and the brightness and amount of operation at the next point are determined. The amount or amount of movement of the theater equipment is known, this determines the amount of movement per step, and the cue table allows a predetermined speed to be set. This allows you to control the vector for fading in or out multiple incandescent lights, and after the fade-in or fade-out time for these incandescent lights has elapsed, the central controller controls multiple fluorescent lights to blink, making the lighting pattern even more impressive. can be done. Furthermore, by referring to a table in which operating programs are recorded, it is possible to control on/off of a plurality of theater equipment.
