[Abstract]:With the rapid development of science and technology, the modern science and technology museum as its product must be faced with independent innovation and breakthrough. As the key of science and technology museum, exhibits design aims to spread scientific knowledge and cultivate scientific interest. In this paper, the model exhibits of the solar system are designed to demonstrate the motion of the solar system to the audience and stimulate the viewers' scientific thinking. The main contents of the research are as follows: 1. The functional requirements of the solar system motion model are analyzed in detail. The overall mechanical structure scheme of the model and the general control scheme of the servo semi-closed loop control system of the motion control card servo motor of the industrial control computer are determined. 2, the design of the mechanical structure scheme of the solar system model is expounded. The design of three big structure modules is introduced in detail, including the rotation and rotation of eight major planetary models, the rotation and luminescence of the solar model and the mechanical structure of the rotation of the moon around the earth. The structural design of the model cover plate and mounting base is briefly described. 3. The hardware system of the solar system model control system is designed and studied. A control system with PCI-1240U motion control card as the control core is proposed. The design of each subsystem of the control system is described in detail, including the control card unit system, the power supply system, the sensor system, the servo motor and the DC deceleration motor system. Finally, the design of the electric cabinet and the arrangement of the electrical components are given. 4, the software design of the model control system is completed. According to the interface requirements of the exhibits model, the overall control idea of the control system is analyzed in detail, and the design scheme of each interactive interface is put forward. The exhibit is an important exhibit in Hunan Provincial Science and Technology Museum. It has been on display for nearly a year. The results show that the exhibits are stable and reliable, simple and beautiful in structure, easy to maintain, and can be viewed by human-computer interactive viewers at specific dates. Special celestial phenomena and demonstration of rotation are in line with the theme of modern science and technology museum.
