Method for controlling planetarium to demonstrate astronomical phenomena and control system

Abstract

The invention relates to a method for controlling a planetarium to demonstrate astronomical phenomena and a control system. The planetarium comprises a controller and a touch-sensitive display. The method comprises the following steps: presetting a control command in the controller; displaying a plurality of graphic blocks which are arranged in a queue on the touch-sensitive display, wherein eachgraphic block is matched with one or more of the plurality of control commands; detecting contact with the touch-sensitive display at the position corresponding to one graphic block in the queue; keeping contact movement during continuous contact with the touch-sensitive display, and making a corresponding contact graphic block move in a following manner; when the graphic block following contact movement is moved to the head end and the tail end of the queue or a preset insertion range in which any two adjacent graphic blocks do not intersect with each other, detecting the disappearance of contact, and inserting the graphic block into a queue position corresponding to the insertion range; detecting the contact in a preset starting area on the touch-sensitive display and the disappearance of the contact, and transmitting a demonstration request to the controller in order to start the planetarium to demonstrate the astronomical phenomena according to the queue sequence.

Description

technical field [0001] The invention relates to the technical field of planetariums, in particular to a method and a control system for manipulating a planetarium to demonstrate astronomical phenomena. Background technique [0002] A planetarium is a popular science instrument that simulates a starry sky performance, also known as a fake astronomical instrument. It displays various celestial bodies seen by people at different latitudes and longitudes on the earth on a hemispherical sky, such as the ups and downs of the sun, moon and stars, and planets passing through the stars. Precession of the Earth's axis of rotation, etc. It can demonstrate in a short period of time the laws of motion of major stars, planets, star clusters and nebulae in the universe, the rising and setting of the sun in the east, and the waxing and waning of the moon. It is intuitive, realistic, vivid and interesting. [0003] However, the traditional planetarium uses the buttons, knobs, switches and o...

Problems solved by technology

[0003] However, the traditional planetarium uses the buttons, knobs, switches and other operating equipment on the controller to cooperate with the broadcasting equipment to realize the demonstration of various astronomical phenomena. The operator must undergo professional training and long-term practice to be competent for the demonstration work, especially in the dark It is carried out in an environment with higher requirements for operators, and the general public is not competent. This makes the astronomical demonstration of the planetarium not close to the people and affects its popularization.

[0004] With the development of the planetarium, people need a more simple and easy-to-learn method of controlling the planetarium for demonstration, providing a more friendly planetarium control experience. The development of computer control systems satisfies this very well. In computer human-computer interaction Compared with mechanical operations such as buttons, knobs, and switches, the operations on the interface are easier to be familiar with and mastered, but even so, the computer human-computer interaction interface of the existing planetarium is still complicated, and there is still a large room for optimization in the control method
