Abstract

PURPOSE:To raise the projection effect of a planetarium by providing an intelligent function for interlocking and executing automatically various controls of the respective projectors interlocked with the movement in the case of executing various movements in conformity with the phenomenon of heavenly bodies. CONSTITUTION:In the case of executing various movements in conformity with various phenomena of heavenly bodies, various controls of the respective projectors interlocked with its movements are interlocked and executed. That is, a host computer 1 reads in necessary data from an external memory device 2, and sends the necessary data to a light controlling sub-CPU 3. The light controlling sub-CPU 3 stores those data on a memory 4, reads in those data at the time point when a diurnal motion is started, and calculates a horizontal system of coordinates of the sun. Subsequently, an azimuth and altitude of the sun which are calculated are collated with a solar position table read in the memory 4 is advance, and to a level of its corresponding azimuth and altitude, each projector 6 is lighted through an interface 5. In such a way, with respect to a series of movements, an intelligent function for interlocking automatically various projectors related to its movements can be realized.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a computer-controlled planetarium in which, when various movements are performed manually, by copying, automatically, etc., each projector related to each movement is The present invention relates to a planetarium equipped with intelligent functions that automatically control frame advance, zoom, lighting, turning off, fade-in, fade-out (dimmer control), etc. according to the progress of the movement.

[Prior art]

In conventional planetariums, each movement system is controlled independently, and each projector's frame advance, zoom,
The 0N10FF, fi light, etc. are each controlled independently and have no relation to each other.

[Problem to be solved by the invention]

Therefore, for example, when creating a sunset effect, the sun approaches the horizon due to its diurnal movement (as the sun approaches the horizon, daylight, green rice, and sun gradually become darker, the sunset gradually becomes brighter, and when the sun sets below the horizon, the sun approaches the horizon). For automatic production, each command is written in the production program, and for manual operation, a series of sequences such as turning off the planet, gradually brightening the planet, and slowly brightening the star, and adjusting the intensity of each projector for manual operation. It had to be operated by hand, which was very cumbersome and difficult to operate.

[Means to solve the problem]

The present invention employs the following means to solve the above problems.

In other words, when a combinator-controlled planetarium performs various movements in accordance with various phenomena of celestial bodies, an intelligent function is provided to automatically control the various projectors in conjunction with the movements. This is a planetarium projection method characterized by the following.

〔Example〕

Table 1 shows the projector and expression purpose linked to each movement.

FIG. 1 is a schematic diagram of the control system.

In the figure, (1) is the host computer, (2) is the external storage device, (3) is the dimming sub CPU, (4) is the memory, (
5) is an interface, and (6) is various projectors.

Figure 2 shows the dimming level of each projector in conjunction with each other at sunset during the diurnal movement.

Each projector automatically adjusts its light as the diurnal movement progresses, as shown in Figure 2.

Figure 3 shows the actual change in sky brightness after sunset.

In the case of a planetarium, it is not possible to simulate the actual sky in terms of illuminance and time, but it is possible to set the sun position control table shown in Table 2 to draw such an illuminance curve.

Table 3 is a latitude variation skyline dimming table.

The skyline lights up at the piece position and level corresponding to this table when the latitude changes.

Now, various projectors at sunset of the sun r1 movement will be explained as an example.

First of all, in Figure 1, the host computer (1
) reads the necessary data from the external storage device (2) and sends it to the dimming sub CPU (3), the start date, month, day, hour and minute of the diurnal movement, the end date, month, day, hour and minute, latitude and longitude of the location, standard time, and the execution time. Send necessary data such as time.

The dimming sub-CPU (3) stores the data on the memory (4), reads the data when the diurnal movement starts, and calculates the horizontal coordinates of the sun.

The calculated sun azimuth and altitude are checked against the sun position table in Table 2, which has been previously loaded into the memory (4), and the corresponding azimuth and altitude levels are entered via the interface (5). Light up each projector (6).

Light control sub CPU (3) is 0. A series of these operations is performed every second, and the dimming level at each point in time is controlled in real time.

In addition, when changing the location due to the skyline projector during latitude movement, the current latitude value is checked with the latitude change skyline dimming table shown in Table 3, which has been loaded into the memory (4) in advance, and the current latitude value is checked at that time. Projects the scenery of the corresponding location based on the skyline piece position and lighting level.

Similarly, for annual motion and precessional motion, tables corresponding to each motion are used to realize seasonal changes and age changes, respectively.

By performing the above control, an intelligent function is realized that automatically links various projectors related to a series of movements.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to realistically express various projection effects that could not be achieved conventionally in synchronization with various phenomena of celestial bodies, and it has the advantage of enhancing the projection effect of planetariums. This is a great invention.
