摘　　要：为了加快以传播科学知识、弘扬科学精神为目的的展品设计技术的快速发展,首先,应用日心说原理设计了一种太阳系运动简易模型。该模型采用研华科技公司的运动控制卡PCI1240U作为控制系统的核心来控制交流伺服电机,以驱动行星模型的公转;同时通过旋转按钮手动控制直流减速电机,以实现模型的自转。其次,设计了导电机构以保证直流减速电机的有效供电。最后,运用VB软件设计了个性化的人机交互界面。研究结果表明,该模行运行情况良好,机械结构简易美观,运转稳定可靠,易于维护,通过人机界面(HMI)可观看特殊天象和特定日期的天象,以及公转演示等。Aiming at rapidly developing of exhibits design,to convey scientific knowledge and promote the scientific spirit,a solar system moving model was designed based on the heliocentric theory.The movement control cards were employed to control AC servo motors,which were used to drive the revolutions of planets;and the rotations of these planets were driven by DC geared motors.Then,the conductive devices were designed to ensure DC geared motors of reliable power supply.Lastly,personalized human machine interface was developed by using VB software.Results indicate that the system shows the outstanding performance such as good work,structural simplicity,stability,and easy maintenance,etc..Through human machine interface（HMI）,special astronomical phenomena,the astronomical phenomenon in any certain date,and the revolution of the solar system can be displayed.
