【摘要】：隨著科學技術的快速發(fā)展，現代科技館作為其產物也必定要面臨著自主創(chuàng)新與突破，而展品設計作為科技館的關鍵，是以傳播科學知識和培養(yǎng)科學興趣為目的的。本文研究設計了太陽系模型展品，向觀眾演示太陽系運動規(guī)律，激發(fā)觀眾的科學思維。研究課題主要內容如下： 1、詳細分析了太陽系運動模型的功能需求，確定模型的總體機械結構方案和“工控機+運動控制卡+伺服電機”伺服半閉環(huán)控制系統(tǒng)的總體控制方案； 2、闡述了太陽系模型的機械結構方案設計。并詳細介紹了三大大結構模塊的設計，包括八大行星模型公轉和自轉部分、太陽模型自轉與發(fā)光部分和月亮繞地球公轉部分的機械結構部分，然后，簡要說明了模型蓋板和安裝座的結構設計； 3、設計研究了太陽系模型控制系統(tǒng)的硬件系統(tǒng)。提出了以研華PCI-1240U運動控制卡為控制核心的控制系統(tǒng)，詳細敘述了控制系統(tǒng)的各個子系統(tǒng)的設計，包括控制卡單元系統(tǒng)、電源系統(tǒng)、傳感系統(tǒng)、伺服電機和直流減速電機系統(tǒng)。最后給出了電器柜的設計和電器元件的布置安排； 4、完成了模型控制系統(tǒng)軟件的設計。根據展品模型界面需求，，詳細分析了控制系統(tǒng)的總體控制思想，并提出了各個交互界面的設計方案。 該展品是承接湖南省科技館的重要展品，已經展出近一年，結果表明，其運行穩(wěn)定可靠，結構簡單美觀，便于維護保養(yǎng)，并由人機交互觀眾可欣賞特定日期天象、特殊天象和公轉演示等運動規(guī)律，符合現代科學技術館的主題。
[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.
