However, in conventional planetariums, it is not possible to manually operate the planetarium during the above-mentioned temporary stop, so various manual operations and explanations can be inserted into the automatic performance to suit various audiences such as elementary school students and general audiences. It was impossible to do so, and the production became uniform.

Furthermore, even if it is possible to manually operate the planetarium when the planetarium is temporarily stationary, if the planetarium is moved manually during the temporary stationary period, a gap will occur between the planetarium immediately before the temporary stationary position and when the automatic performance returns, making it impossible to perform the automatic performance. It is something.

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, 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 composed of a microcomputer shown in FIG.

In FIG. 2, a central processing circuit (hereinafter referred to as CPU) is connected to a semiconductor or core memory, etc. via a bus line consisting of an address bus AB and a data bus DA.
A memory M to which data can be randomly input/output is connected. 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 a card and a magnetic tape on which control data in which control objects and control contents are digitally coded is recorded. 13 and 14 are stellar projection sphere lamps,
Control circuits 15 and 16 for control objects such as diurnal motors, etc.
address bus AB and data bus DB via interfaces 17 and 18.
connected to.

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

21 is a display circuit that also serves as a manual operation switch for manually operating the controlled objects 13 and 14, and is connected to the address bus AB and data bus DB via an interface 22, and is connected to various devices such as the keyboard K and switch SW. A lamp is installed behind a semi-transparent board with the name of the controlled object written on it on the operating table, which has a collection of manually operated switches. provided.

The keyboard K is provided with an interrupt instruction key KI, and the switch SW is provided with a return switch S for canceling the interrupt.
A WI is provided.

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 for setting the brightness of the dimmable illumination lamp.

The output signal of the manual setting device MN is now 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.

Card Moko is the first card (control number 1) on which one data is written on one card according to the production program.
) is digitally encoded with control data that says "turn on the polar star projection sphere lamp". This control data is read by the card reader CR and sent via the interface 11 to the address bus AB and data bus DB. and is input to the CPU.

The control data input to the CPU is transferred to the address bus AB again.
, and is stored at address 1 of memory M on data bus DB. At the same time, the control data is transmitted to the control circuit 15 by activating the interface 17 for the Wusei projection sphere lamp, and sending the control data indicating "turn on" to the control circuit 15, which activates the polar star projection sphere lamp. 13 is turned on. Further, control data and other data are input to an interface 22 of a display circuit 21 which also serves as a manual operation switch. Then, the display lamp of the Gosei projection sphere lamp 13 is brightly lit on the operation table to indicate that the Gosei 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' as with the first card. This is input.

This control data is transferred from the CPU to address bus AB and data bus DB, and is stored at address 2 of memory M. At the same time, similarly to the case of the star projection sphere lamp 13, the control circuit 16 rotates the diurnal motor 14, which is the controlled object, forward to the origin, and displays a display that also serves as a manual operation switch corresponding to the forward rotation of the diurnal motor 14. The lamp of circuit 21 is lit brightly. 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 KI is pressed, the memory M temporarily stores the control data of the control circuits 15 and 16 at that time, such as the illuminance of the gutter projection bulb lamp 13 and data representing the positions of the annual and daily Fujis. It looks like this. Further, when the return switch SWI 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 in which an automatic planetarium presentation is performed based on the control data stored in the memory M will be described with reference to the flowchart shown in FIG.

First, a start switch (not shown) is pressed to set address 1 of memory M to zero. Next, address 11 of this memory M
Add to make 1=1. And 1 from address 1 of memory M
The control data stored at the address, for example, "turn on the polar star projection sphere lamp" is called up to the CPU, and the CPU determines whether this control data indicates the end. Since this control data is not completed (NO), the CPU puts this control data on the address bus AB and data bus DB. This control data is inputted only to the display circuit 21 which also serves as a manual switch via the interface 22 corresponding to the star projection sphere lamp, and lights the lamp brightly. At the same time, the interface 17 corresponding to the stellar projection sphere lamp is activated by the CPU.
Control data for "turn on" is input. This input activates the control circuit 15 to light the polar star projection sphere lamp 13. Next, the address 1 of the memory M where the control data is stored is incremented by 1 in the order of the performance program, and the next control data is called.

In this way, the CPU determines the end by controlling the planetarium while incrementing address 1 of memory M by 1 and sequentially calling control data, and outputting end data after exiting the final control data of memory M. to end the planetarium's automatic presentation. If the interrupt key KI is operated during the automatic performance as described above, the operation will shift to ■ in the flowchart in Figure 4, and the time tl at the time the interrupt key KI is pressed is read from the reference clock CL. This time is stored in memory M.

Thereafter, this reference clock CL is cleared. On the other hand, the position DI 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, the voltage V1 that represents the brightness of dimmable lighting lamps, etc.
(shown in FIG. 5) etc. are 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 lighting lamps that can yield light, the setting value of the manual operation dial MN and the digital data VI at the time tl of the memory M are compared in the input PU, and when the two match, it is determined that manual production is possible. Become. therefore,
For example, when the manual setting dial of a lighting lamp is gradually changed from zero (off position) to the brighter side, the setting value Vs
is compared with the stored value VI by the CPU, and when Vs=VI, the performance is switched to manual. The brightness of the gorge surface changes depending on the setting value of the manual setting dial. Note that the motors that drive the diurnal axis, etc., stop at the same time as the interrupt, so they are driven at the same time as the manual setting dial is set.
Set to any 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. Turn on the return switch SWI at time t2 after completing the specified manual production.The position D1 on the diurnal axis immediately before the start of the interrupt, the voltage V1 corresponding to the brightness of the technical screen, and other values are stored in the memory M. Control data is read.

Then, the diurnal motor is driven so that the position of the diurnal axis is set to DI, and the voltage of the illumination lamp is adjusted so that the brightness of the dimming lamp that can provide light is set to VI.

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 detailed above, according to the present invention, it is possible to switch from automatic to manual presentation at any time during the automatic presentation of the planetarium by operating an interrupt key, thereby increasing the degree of freedom of presentation of the planetarium. In addition to this, the data immediately before the interrupt is stored in the storage means, and after the interrupt ends, this stored data is read out and the content of the performance is restored to the state immediately before the interrupt. Therefore, the performance that continued before and after the interrupt can be automatically performed. It can be done.
