Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a planetarium presentation device capable of automatic presentation and manual presentation.

In conventional planetariums that can perform automatic performances, in order to explain programs other than this automatic performance program during the automatic performance, an automatic performance pause switch is installed. He explained verbally using a pointer, etc., and after the explanation was completed, he operated the switch to return to automatic production.

However, in conventional planetariums, it is not possible to manually operate the planetarium during the above-mentioned pause, so elementary school students or general audience members may interrupt the automatic production with various manual operations or explanations to suit different audiences. This was not possible, and the production became uniform.

Furthermore, even if manual operation of the planetarium is enabled when paused, if the planetarium is moved manually during pause, if there is a gap between the state of the equipment when paused and the state instructed by manual operation, it will not work smoothly. This is not desirable because it cannot be migrated and puts a burden on the equipment.

This invention was made in order to solve the above-mentioned problem, and it is possible to interrupt manual performance during automatic performance, and also provides means for storing automatic performance data immediately before the interruption, so that the manual performance data is stored in the storage means. An automatic presentation device for a planetarium that prevents discontinuity in presentation data such as the annual axis, diurnal axis, and brightness of the projection surface by performing manual presentation after matching the automatic presentation data immediately before the interruption. The purpose is to provide

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a planetarium, 2 is a control console for controlling the planetarium 1, and 3 is a control console for controlling the planetarium 1.
4 is a dome with a projection surface on which constellations, etc. are projected;
indicates a seat.

The control console 2 incorporates a control device constituted by a microcomputer shown in FIG. In Figure 2, the central production circuit (hereinafter
A memory M, which is made of a semiconductor or a core memory, and can randomly input and output data, is connected to the CPU (called a CPU) via a bus line consisting of an address bus AB and a data bus DB. A card reader CR and a cassette deck CD, which are control data input devices, are simultaneously or selectively connected to the address bus AB and data bus DB via interfaces 11 and 12, respectively. The card reader CR and the cassette deck CD read from cards and magnetic tapes on which control data, which is a digital code of control objects and control contents, is recorded. 1
3 and 14 are objects to be controlled such as a star projection lamp and a diurnal motor, which are controlled to be activated or deactivated by control circuits 15 and 16, respectively.
Address bus AB and data bus via 7 and 18
Connected to DB.

In addition, a keyboard K for manually inputting data is connected to the address bus AB and data bus DB via an interface 19.
A switch SW for sending input from the keyboard K to the CPU is connected via an interface 20.

21 is a display circuit that also serves as a manual operation switch for manually operating the controlled objects 13 and 14;
Address bus via interface 22
AB and data bus DB.A lamp is installed behind a semi-transparent board on which the name of the controlled object is written on the control table that collects various manually operated switches such as keyboard K and switch SW. The switch can be turned on by pressing a transparent plate, and there are the same number of switches as there are objects to be controlled.

The keyboard K is provided with an interrupt instruction key _K1 , and the switch SW is provided with a return switch _SW1 for canceling the interrupt.

Also, for manual production, a manual setting device MN is provided for manually setting the positions of the diurnal and annual axes and setting the brightness of the dimmable lighting lamp.
The output signal of the manual setting device MN is applied to the controller 16.

CL represents a reference clock and supplies a time signal to the CPU.

The programs shown in FIGS. 3 and 4 are written in the control device shown in FIG. 2.

Next, a case where automatic performance is performed while inputting control data from the card reader CR to this automatic performance circuit will be explained.

The card has one piece of data written on it according to the performance program.The first card (control number (1) is ``Light up the star projection lamp'')
If the control data with the content is digitally coded, this control data is read by the card reader CR, and input to the CPU via the interface 11 on the address bus AB and data bus DB. The control data input to the CPU is again transferred to the address bus AB and data bus DB, and is stored at address 1 in the memory M. At the same time, the control data activates the stellar projection lamp, for example, the interface 17, and sends the control content of the control data, ie, data of "turn on" to the control circuit 15, which activates the control circuit 15 to turn on the stellar projection lamp 13. Turn it on. Further, the control data is input to an interface 22 of a display circuit 21 which also serves as a manual operation switch. Then, the indicator lamp of the stellar projection sphere lamp 13 is brightly lit on the operation table to indicate that the stellar projection sphere lamp 13 is lit.

Next, when the control data of control number (2), for example "rotate the diurnal motor 14 forward to the origin", is input from the second card, this control data is sent to the CPU in the same way as the first card. is input. This control data is transferred from the CPU to the address bus.
AB and data bus DB are stored at address 2 in memory M. At the same time, the star projection lamp 13
In the same manner as in the above case, the control circuit 16 causes the diurnal motor 14 to be controlled to rotate forward to the origin, and at the same time brightly lights up the lamp of the display circuit 21 which also serves as a manual operation switch corresponding to the forward rotation of the diurnal motor 14. .

Subsequently, control data is input in the same manner from the third and subsequent cards and stored in the memory M in order.

Subsequent performance programs are also stored in the same manner. When the interrupt key _K1 is pressed, the memory M temporarily stores the control data of the control circuits 15 and 16 at that time, such as data representing the illuminance of the star projection lamp 13 and the position of the annual axis and diurnal axis. I'm starting to do that. When the return switch _SW1 is pressed, the interrupt program is canceled and the data stored in the memory M at the time of the interrupt is read out.

Next, a case where an automatic planetarium presentation is performed based on the control data stored in the memory M will be explained with reference to the flowchart shown in FIG.
First, a start switch (not shown) is pressed to set address I of memory M to zero. Next, 1 is added to address I of this memory M to make I=1. Then, the control data stored in memory M from address 1 to address 1, for example "turn on the star projection lamp"
This is called to the CPU, and the CPU determines whether this control data indicates an end.
Since this control data is NO, which is not the end,
The CPU puts this control data on the address bus AB and data bus DB. This control data is inputted via the interface 22 corresponding to the star projection sphere lamp only to the corresponding display circuit 21 which also serves as a manual switch, and lights the lamp brightly. Interface 1 that also supports a star projection lamp
7 is operated by the CPU, and control data for "turning on" is input. This input activates the control circuit 15 to turn on the star projection sphere lamp 13.

Next, the address I of the memory M where the control data is stored in the order of the effect program is incremented by 1, and the next control data is called. In this way, the CPU determines the end by controlling the planetarium while incrementing the address I of the memory M by 1 and sequentially calling the control data, and outputting the end data after the final control data of the memory M is output. to end the planetarium's automatic presentation.

If you press the interrupt key K ₁ during the automatic performance as described above, the operation will shift to the flowchart shown in Figure 4, and the time t ₁ at the time you press the interrupt key K ₁ will be the standard. This time is read from the clock CL and stored in the memory M. After that, this reference clock CL is cleared.

On the other hand, the position D ₁ of the diurnal axis at the interrupt start time t ₁ is detected by a detector provided in the control circuit 16, and digital data indicating the angle is stored in the memory M. Further, a voltage V ₁ (shown in FIG. 5) representing the brightness of a dimmable lighting lamp, etc., is also stored in the memory M.

Then, the automatic performance is stopped, and the operation is performed according to the settings of the manual operation switch 21 and manual operation dial MN. In this case, for dimmable lighting lamps, the setting value of the manual operation dial MN and the digital data V ₁ at time t ₁ in the memory M are compared in the CPU, and manual production is possible when the two match. becomes. Therefore, when the manual setting dial of a lighting lamp is gradually changed from zero (off position) to a brighter one, the set value V _s is compared with the stored value V ₁ in the CPU, and at the point when V _s = V ₁ . to switch to manual production. The brightness of the projection surface changes in accordance with the setting value of the manual setting dial.

Note that the motor that drives the diurnal axis, etc. is stopped at the same time as the interruption, so it is driven at the same time as the manual setting dial is set, and is set to an arbitrary position.

It should be noted that the illumination lamp, which can only be turned on and off, maintains the state at the time of the interruption unless the manual operation switch 21 is manually operated even after the interruption.

It was stored in the memory M that the return switch SW ₁ is turned on at time t ₂ after the specified manual performance is completed.
The position D ₁ on the diurnal axis immediately before the start of the interrupt, the voltage V ₁ corresponding to the brightness of the projection surface, and other control data are read out.

Then, the diurnal motor is driven so that the position of the diurnal axis is set to _D1 , and the voltage of the illumination lamp is adjusted so that the brightness of the dimmable projection lamp is set to _V1 .

Other various mechanisms, such as the annual axis and the lamps representing each constellation, are also set to the state immediately before the start of the interrupt in a similar manner.

Further, the reference clock CL is set to the time immediately before the start of the interrupt read from the memory M, and timekeeping is restarted. Then, at time _t3 , the automatic performance is returned to, and the automatic performance continues from the state immediately before the interruption.

As described in detail above, the present invention includes a first storage means for storing a series of control data in which control objects provided in a planetarium and their control contents are encoded, and a first storage means for sequentially reading out the control data from the first storage means.
automatic presentation control means for controlling each controlled object using control data to perform automatic presentation; manual presentation data input means for inputting manual presentation data; A manual performance control means for controlling and performing a manual performance, an interrupt command input means for inputting an interrupt command, a second storage means for storing data of the control being performed immediately before the interruption, and a second storage means for storing data of the control being performed immediately before the interruption. In response to the interrupt command from the interrupt command input means, the automatic performance control means is stopped, the control data immediately before the interruption is stored in the second storage means, and the data input from the manual performance data input means is stored in the second storage means. 2. Interrupt control means that permits control by the manual performance control means when the control data immediately before the interruption stored in the storage means is matched, so that it is possible to switch from automatic performance to manual performance at will. This increases the degree of freedom in production, and has the advantage that the transition is smooth and does not cause damage to the equipment being controlled.
