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 automatically, in order to explain programs other than this automatic performance program during automatic performance, an automatic performance pause switch is installed, and this switch is operated to stop the automatic performance, allowing the commentator to He explained verbally using a handheld pointer, etc., and after completing the explanation, he operated the above 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 it is possible to perform various manual operations and explanations without interrupting the automatic production to suit various audiences such as elementary school students and general audiences. This was not possible, and the production became uniform.

Furthermore, even if manual operation of the planetarium is enabled when the planetarium is paused, if the planetarium is moved by manual operation during the pause, if there is a gap between the state of the equipment at the time of pause and the state instructed by manual operation, it may not be possible to operate the planetarium 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
A means for storing the automatic presentation data immediately before the interruption is provided, and the manual presentation is performed after the manual presentation data matches the automatic presentation data immediately before the interruption stored in the arrangement means, thereby adjusting the annual axis, diurnal axis, and projection. It is an object of the present invention to provide an automatic presentation device for a planetarium that prevents presentation data such as surface brightness from becoming discontinuous.

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, 3 is a dome having a projection surface on which constellations and the like are projected, and 4 is a seat.

The control console 2 incorporates a control device constituted by a microcomputer shown in FIG. In FIG. 2, the central processing circuit (hereinafter referred to as cpU) is connected to a semiconductor or core memory, etc. via a path line consisting of an address bus (AB) and a data bus (DB).
A memory (M) is connected to which data can be input/output at random. This address bus (AB), data bus (
DB) is equipped with a card league (C
R) and a cassette deck (CD) are connected simultaneously or selectively via interfaces (11) and (12), respectively. Card league (CR) and cassette deck (CD)
) reads control data in which the control object and control contents are digitally encoded from cards and magnetic tapes. (x3) and (i4) are controlled objects such as a star projection lamp and a diurnal motor, respectively, and control circuits (1'5) and (
16), and the address bus (AB
), connected to the data bus (DB).

In addition, this address bus (A n ), data bus (
DB) has a keyboard (K) for manually entering data.
is connected via an interface (19), and a switch (SW) for sending input from the keyboard (I() 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 control pair v (13) and (14), and is connected to an address bus (AB) via an interface (22).
, which is connected to the data bus (DB), and has a lamp behind a semi-transparent board with the name of the controlled object written on it on the operation table where various manually operated switches such as a keyboard (K) and switches (SW) are collected. The switch is turned on by pressing the translucent plate, and the number of switches is the same as the number of 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 (SW4) for canceling the interrupt.

Further, for manual effects, a manual setting device (MN) is provided for manually setting the positions of the diurnal axis and the annual axis and setting the brightness of the dimmable lighting lamp. Manual setting device (MN
) is adapted to be applied to a 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 will be described in which automatic performance is performed while inputting control data from the card league (CR) to this automatic performance circuit.

Cards have one date or one card according to the performance program (control number (1)
)) If the control data is digitally encoded, the control data is read by the card league (CR) and sent via the interface (11) to the address bus ( AB),
The data is input to the CPU via the data bus (DB). C.I.
) The control data input to U is transferred again to the address bus (A
B), take the data bus (1) B) and save the memory l) (
M) is stored at address 1. At the same time, the control data activates the interface (17), for example, a star projection sphere lamp, and sends the control content of the control data, ie, data of "turn on" to the control circuit (15), and activates the control circuit (15). Turn on the star projection lamp (13).

Furthermore, the control data is displayed on a display circuit that also serves as a manual operation switch (
21) is input to the interface (22).

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 entered from the second card, this control data will be transferred to the first card. is input to the CPU in the same way. This control data is transmitted from the CPU to the address bus (AB) and the data bus (D
B) and is stored at address 2 in memory (M). At the same time, the control circuit (16) controls the diurnal motor (1
4) forward to the origin, and the diurnal motor (14
) lights up brightly the lamp of the display circuit (2t) which also serves as a manual operation switch corresponding to forward rotation of the motor.

Subsequently, control data is input in the same manner from the third and subsequent cards and stored in the memo IJ (M) in order.

Subsequent performance programs are also stored in the same manner.

When the interrupt key (K1) is pressed, the memory M stores the control data of the control circuits (15) and (16) at that time, such as the illuminance of the star projection lamp (13) and the position of the annual axis and diurnal axis. It is designed to temporarily store data representing the . When the return switch (swl) is pressed, the interrupt program is canceled and the data stored in the memo 1) (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 of FIG. 3. .

First, press the start switch (not shown) and read the memory (M
) address (1) is set to zero. Next, add (1) to address (1) of this memory (M) to make it 1-1. Then, the control data stored in memo IJ (M) from address 1 to address 1, for example, "turn on the "Se" star projection sphere lamp", is CP.
Call U, CI) U determines whether this control data indicates an end. Since this control data is not finished (No), the CPU transfers this control take to the address bus (A B ) and the data bus (1
) Put it on B). 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. At the same time, the interface (17) corresponding to the stellar projection sphere lamp is activated by CI)U, and control data for "turn on" is input. This input activates the control circuit (15) to light the star projection 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 planetarium is controlled while sequentially calling the control data by incrementing the address (1) of Memo 1) (M) by 1, and the end data is output after the final control data of Memo IJ (M) is output. By this, C
The PU determines the end and ends the automatic presentation of the planetarium.

While the automatic performance is being performed as described above, press the interrupt key (
When K 1 ) is operated, the operation shifts to ■ in the flowchart of FIG. 4, and when the interrupt key (K 1 ) is pressed, the time at point (tl) is read from the reference clock (CL),
This time is stored in the memo IJ (M). This reference clock (CL) is then cleared.

On the other hand, the position (Dl) of the diurnal axis at the interrupt start time (tl) is detected by a detector provided in the control circuit (16), and digital data indicating the angle is stored in the memory (
M). Also, note IJ (
M).

Then, the automatic production stops and the manual operation switch (21)
and the settings of the manual operation dial (M N ). In this case, for dimmable lighting lamps, the setting value of the manual operation dial (MN) and the memory (M
) at time (tl) is C
l) They are compared within Ll, and if the two match, manual production is possible. Therefore, if the manual setting dial of a lighting lamp is gradually changed from zero (off position) to the brighter side, the set value VS will be changed to CP Ll and stored in V.
1, and when Vs=V1, the performance is switched to manual. 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.

Note that the illumination lamp, which is only 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.

At time t2 after the specified manual performance is completed, the return switch SW is turned on.
When I is turned on, the position of the diurnal axis (Dl) immediately before the start of the interrupt, the voltage (■1) corresponding to the brightness of the projection surface, and other control data stored in the memory (M) are read out.

The diurnal motor is then driven so that the position of the diurnal axis is (D1), and the brightness of the dimmable projection lamp is set to ■1.
The voltage of the illumination lamp is adjusted so that

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.

Also, the reference clock is set to the time immediately before the start of the interrupt read from the ct4 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 a control object provided in a planetarium and its control contents are coded, and a first storage means for sequentially reading out the control data from the first storage means and controlling the object. automatic performance control means that controls each control target based on data to perform automatic performance, manual performance data input means that inputs manual performance data, and controls each control target by input from the manual performance data input means. A manual performance control means for performing 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 an interrupt command during automatic performance. The automatic performance control means is stopped in response to an interrupt command from the input means, 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. Since the device is equipped with an interrupt control means that allows control by the manual presentation control means when the control data matches the control data stored immediately before the interruption, it is possible to switch from automatic presentation to manual presentation at will. This has the advantage that it not only increases the degree of freedom in production, but also allows smooth transitions without causing damage to the equipment being controlled.
