基于51的智能书桌设计（STC89C52） 毕业论文+仿真源文件

---

摘要：儿童是一个非常特殊的群体，无论是在生理、心理还是行为上都有显著区别于成人的特点：他们的身体依旧在不断发展，还没成熟；他们的智力也正在塑造，因此他们的需求是随着身心的发展而不断变化的。同样，儿童的这些特点使得儿童书桌明显区别于成人家具。本论文根据这些特点，探究书桌设计在物联网时代如何更好运用智能化手法来迎合儿童的健康成长的尺寸、造型、色彩与智能功能等的需求。将智能化控制系统与传统书桌设计相结合，满足学龄儿童成长过程中对书桌升降高度、调节角度、视力健康、坐姿正确、环境安全等的健康需求。通过内置智能处理系统和简便界面操作系统的调节来实现书桌调节的智能化，满足孩子健康成长需求，预防近视、驼背、脊椎弯曲等疾病的发生，提供更加优化的学习环境。最后将理论研究与设计实践进行结合，在造型、功能、色彩等方面按照总结的最优尺寸值和参考技术进行新型智能书桌的实物和概念化设计，拓展儿童智能书桌使用上的延续性。

Abstract：Children are a very special group who are different from the adult, there are significant characteristics different from the adult whether in physiological, psychological or behavioral. Not only Their body and mind are still constantly developing, not being mature, but their intelligence is also being shaped, so their needs are changing with the development of the physical and mental. Again, these features make children’s furniture significantly different from adult furniture.According to these characteristics, this paper research the desk how to make better use of intelligent design desk approach to meet the size, shape, color and intelligent function needs of the children’s healthy growth in the era of things.The intelligent control system combined with traditional desk design, to meet the needs of school-age children grow up healthy desk in Lift height, adjust the angle, visual health, proper posture, environmental security, etc.Built-in intelligent processing system and interface operating system to achieve intelligent desk adjusted to meet the needs of healthy growth of children, to prevent the occurrence of myopia, kyphosis, curvature of the spine and other diseases.providing a more optimal learning environment.Finally, combining theoretical research and design practice to make the new smart desk physical and conceptual design in accordance with the summary of the optimal size of the reference value and technology in the shape, function, color and other aspects. In this way ,we can expand the continuity of children’s intelligence desk use.
