Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic presentation method for a planetarium.

Conventionally, as a method for automatically producing a planetarium, a director skilled in operating a planetarium manually operates a console to perform a series of productions from sunset to sunrise, and at the same time, interlocking data input from the console, A copy performance method is known in which various analog data such as light amount data is stored on a magnetic tape and the magnetic tape is subsequently played back to repeat the same performance as a skilled performance.

The imitation production method allows you to produce subtle changes according to your preference, such as at sunrises or sunsets, which have delicate sensations, but on the other hand, it is difficult to create complex switches over the entire production time, for example, an hour. This required a high level of skill and a great deal of effort from the operator.

In order to solve the above-mentioned inconveniences of imitation presentation, a program production method has been proposed in which a program is created using digital data stored in a data card or the like, and a planetarium is automatically produced according to this program.

In the program performance using the data card, complicated switch operations can be performed easily and accurately using the data card, and the labor of the operator can be saved. However, with the program performance method based only on digital data stored on a data card, the movement speed and brightness of the projector etc. can only be adjusted in stages.
It was not possible to produce the effect of subtle continuous changes that could be reproduced by copying. Also,
If fine adjustments are to be made in these program presentations, a large amount of data and a large computer are required, placing a heavy burden on the program designer. Therefore, with the above-mentioned program performance based only on digital data, it has been virtually impossible to replace the conventional imitation performance.

The present invention has the advantage of imitation performance in that it can reproduce subtle continuous changes, and is a novel method that eliminates the disadvantage of imitation performance in that complicated switch operations must be performed over a long period of time. This provides an automatic planetarium presentation method.

More specifically, the present invention stores various analog data such as a series of movement data and light intensity data inputted from an operation console in a first storage device in order to produce scenes that change continuously and subtly such as sunset and sunrise. A series of motion data, light amount data, etc. that are input from a digital data input device to memorize and produce long-term scenes with simple changes but a large number of control objects, such as the diurnal motion of stars and planets. various kinds of digital data are stored in a second storage device, and the data are stored in the first storage device in accordance with a presentation program for specifying the presentation order of each of the above-mentioned scenes and for sequentially presentation of the above-mentioned scenes in the specified order. By sequentially reading various data stored in the device and the second storage device, and automatically operating the planetarium main unit and various peripheral projectors according to the read contents, the data stored in the first storage device is By reproducing the contents stored in the device, subtle continuous changes can be reproduced, and in situations such as the diurnal motion of stars and planets, by reproducing the contents stored in the second storage device. By reproducing a long scene in which a large number of control objects are simply changed, and by sequentially producing each of the above scenes in an order controlled by a production program, the entire production from sunset to sunrise can be automatically and continuously performed. It is something that is done.

To explain the embodiment, reference numeral 1 denotes an operation console having control knobs for controlling the movement of the planetarium main unit 11, dimming, and adjusting various peripheral projectors 14-1 to 14-n. Reference numeral 2 denotes a central processing unit, which is connected to the console 1 and controls the movement of the planetarium main unit 11 adjusted by the console 1, dimming, and various peripheral projectors 14-1 to 14-1.
Data regarding blinking of 14-n, etc. is input.
3 is a digital data input device having an optical card reader, which is connected to the central processing unit 2 and reads planetarium production data (digital data) recorded on the card 4 and inputs it to the central processing unit 2. A clock 5 is connected to the central processing unit 2 and inputs a reference time. 6 is a keyboard connected to the central processing unit 2;
The central processing unit 2 is connected to the central processing unit 2 to call up storage devices 7 and 8, which will be described later, and to display the production operation time.
It has a key for inputting information. 7 is a first storage device using a 1/2-inch wide magnetic tape as a storage medium, which is connected to the central processing unit 2 and is used as an analog for adjusting the light amount and movement speed related to the planetarium main unit 11 of the operation console 1 during copy production. Continuously stores data as an analog signal. 8 is a second storage device having a core memory, which is paired with the central processing unit 2, and is used to store the card 4 in program performance.
The digital data is stored as a digital signal.

The first storage device 7, which uses a magnetic tape as a storage medium, is suitable for storing analog data of a training performance and reproducing it. In the tracing performance, light amount data, motion data, etc. change slightly, but the first storage device stores such data as it is in analog form, and then stores it in the same way as the input data. It can be reproduced in analog form. By the way, in order to store the analog data in the second storage device 8 using the core memory as a storage medium, it is necessary to sample it at predetermined time intervals and to change the sampling data A/D. However, in order to reproduce subtle changes such as sunset and sunrise, it is necessary to shorten the sampling time.
In addition, it is necessary to have a wide range of gradations, and if A/D conversion is performed to satisfy these conditions,
The amount of digital data will be enormous. On the other hand, as described above, according to the first storage device 7 which can store analog data as it is in analog form, there is no need to perform data sampling or A/D conversion, and a large amount of data can be stored. can be easily memorized with good reproducibility.

On the other hand, the second type uses core memory as a storage medium.
The storage device 8 stores data in a digital format, and is suitable for storing program performance data in the form of digital data and reproducing them. By the way, when attempting to store the above digital data in the first storage device 7, the digital data must be FM modulated to change to analog data, and then stored, and when further read out, the analog data must be demodulated into digital data. necessary, and the configuration becomes complicated. On the other hand, according to the second storage device 8 which can store digital data as it is in digital form as described above, there is no need to perform modulation or demodulation, and the structure can be simplified. Furthermore, if the core memory capacity is insufficient for digital data,
Similar to the second storage device 8, the data may be stored in an external storage device 9 whose storage medium is a digital cassette tape, magnetic disk, or the like that can store digital data in its original form.

Various peripheral projectors 14-1, 14-2...14-n are projectors for enlarged photographs of the Moon, Venus, Mars, Jupiter, Saturn, etc., meteor projectors, solar projectors, skyline projectors, constellation picture projectors, etc. It is made up of In addition, this device 11 and various peripheral projectors 14-1, 14-2...14-n,
A feedback signal is input to the central processing unit 2 to ensure the reliability of its operation.

Next, a case will be described with reference to FIG. 2 in which the entire performance from sunset to sunrise is recorded by the planetarium having the above configuration.

First, the card 4a is inserted into the digital data input device 3.
is read by the optical card reader, and the central processing unit 2 is instructed to start the program. Next, the card 4b is used to designate a copy effect and the clock 5 is stopped. In this state, most of the planetarium main unit 11 and various peripheral projectors 14-1 to 14-n are off, and the planetarium main unit 11
Only the sun projector and the dome light illuminating the dome are on.

In this state, the director for copy production is in a state where he or she can freely produce the planetarium by operating the switches and volume of the console 1.
From here, the sunset scene is imitated and produced (symbol A). Specifically, first, the director restarts the stopped clock 5, and lights up the twilight projector and the sunset projector in a bright and dark state, respectively. Then, the brightness of the dome light is gradually dimmed and the sunset projector is gradually brightened, and after sunset, the brightness of the sunset projector is gradually dimmed and only the twilight projector is turned on. In addition, along with these operations, the motor for diurnal movement is rotated, and the moon, planets, stars,
Light up the galaxy projector in the dark and gradually increase its brightness. Then, the brightness of the mesoprojector is gradually dimmed and turned off, and the brightness stops changing after a completely starry sky is reached. This completes the sunset imitation effect, and this effect is all stored in the first storage device 7 as an analog signal.

When the imitation performance of the sunset scene is completed, the clock 5 is temporarily stopped, and a completion signal of the imitation performance is input from the keyboard 6 or the console 1 to the central processing unit 2.
Then, the central processing unit 2 outputs a reading signal to the optical card reader of the digital data input device 3, and the reader starts reading digital data from the card _4c1 again. From here, the program performance of the scene of the diurnal motion of the stars after sunset begins (symbol B) and the clock 5 restarts. This program effect is stored as a digital signal in the second storage device 8 via the central processing unit 2. Data card 4c ₁ , 4c ₂ ...4
In cn, write the name of the object to be controlled, for example, the diurnal motion system related to the planetarium main unit 11, the constellation picture projector, etc., and the control details, such as rotating the motor of the diurnal motion system in the normal direction around the diurnal motion axis. Write down things like rotating it in 2 minutes per rotation and lighting up the constellation picture projector. The data cards 4c ₁ , 4c _{2 .} . . 4cn can also record the performance time of each performance device, for example, the lighting time of the constellation picture projector. If the performance time is not recorded on the data card 4c ₁ , 4c ₂ ...4cn, measure the time from the start of the performance using the clock 5,
When a predetermined time has arrived, a key on the keyboard 6 is pressed and the time is stored in the second storage device 8 via the central processing unit 2. These data cards 4c ₁ , 4
In the program performance using _c2 ...4cn, the card signal is a digital signal, so the controlled light amount and speed change stepwise or simply change over a predetermined period of time. Of course, by increasing the number of cards, more delicate light control and speed control are possible.

The series of program effects ends when the optical card reader reads the card 4d specifying the imitation effect and inputs it into the central processing unit 2, and the clock 5 stops operating. Then, it becomes a copy performance again (symbol C). The director operates the operation console 1 to start the presentation of the sunrise scene and restarts the clock 5. The sunrise effect is performed by the opposite operation to that for the sunset. The contents of this manual performance are stored in the first storage device 7 as an analog signal.

When the imitation performance of the sunrise scene is completed, the director stops the clock 5 and inputs a signal for the end of the performance to the central processing unit 2 via the console 1 or the keyboard 6. Thereby, the optical card reader reads the card again, and when the program end card 4e is read, the entire performance is completed and all the devices stop their functions. As described above, the entire planetarium performance is recorded.

The above-mentioned operations are performed in the following order: imitation performance (day's entrance), program performance (star's diurnal motion scene), and imitation performance (day's entrance). Various combinations of program performance and performance can be made. In subsequent performances, by pressing the re-presentation key on the keyboard 6, the same performance will be reproduced any number of times based on the memories in the first storage device 7 and the second storage device 8. Note that the program presentation is not limited to the use of cards, but may also use sun-hole tape or the like. In addition, depending on the time, location, and other conditions or environment of the performance, you can freely arrange the planetarium performance by rearranging only the program cards, or changing the performance part, and further rearranging both. , and its production is simple as it only requires partial modification of the current content. Of course, even if you start over from the beginning, there is no need to take into account time loss due to production errors compared to the copy production method.

By the way, in a combined performance of copy performance and program performance, it is necessary to maintain the same performance state before and after switching between copy performance and program performance during the recording operation of all performances. For example, in a copy performance, the brightness of the lamp is lit at 80% of the rated brightness, and then when switching to a program performance using a card, the brightness of the lamp is set on the card.
Even if you enter data that should be 80%, in reality, when switching, there will be subtle changes in the voltage supplied to the lamp, and the brightness of the lamp will change momentarily, giving an unnatural feeling to the audience. . This also applies when switching from program performance to imitation performance. Therefore, in the present invention, in order to prevent discontinuous changes at the time of switching in the recording work of the above-mentioned performance, when switching from copy performance to program performance, the data to be stored in the card is ``maintaining the current status'' or ``setting the lamp brightness and motor rotation of the imitation effect to a predetermined value within a certain period of time from the current status, i.e. specifying only the amount of change from the current status and the time to do so.'' designation of
By using two types, discontinuous changes due to switching are prevented. Furthermore, in the case of switching from a program performance using a card to a copy performance, the output by the director's operation once matches the current performance state, that is, the final output state using the card, and then the actual copy performance begins after a slight change. Discontinuous changes are prevented by starting the performance.
In this case, switching can be performed for each individual projector or drive motor. Note that when switching from imitation performance to program performance using cards, the current state of imitation performance may be maintained if no data is specified with the card.

As is clear from the above explanation, according to the method of the present invention, by reproducing the contents stored in the first storage device, subtle continuous changes can be reproduced. In this method, a long scene in which a large number of control objects are simply changed is reproduced by reproducing the contents stored in the second storage device, and each of the above scenes is reproduced in the order specified by the production program. This planetarium automatically and continuously performs the entire production from sunset to sunrise by sequential production, and as a whole, it successfully reproduces scenes with subtle continuous changes, and significantly reduces the labor of the operator. can be performed automatically.
