智能健康秤的设计.pdfVIP

摘 要 社会快速发展、物资变得丰富，然而伴随而来的“富贵病”却悄然侵蚀着人 们的身体，合理控制高热量食物的摄入量就势在必行。而针对热量难以直观认 识的难点，我在毕业设计中，完成了智能健康称的设计，本毕业设计说明书主 要介绍了以单片机为核心的智能健康秤的各个部分。设计结合了信息检测、信 息传输、信息处理以及单片机技术及计算机编程等多方面的知识，实现了智能 化控制下实现对食物称重，并可以换算出常见食物热量的功能。不仅满足了基 本称重要求，有着优异的精确度和稳定性，而且实现了热量换算功能，进一步 贴近了生活，也无需更多的成本投入，为电子秤的发展提供了新的思路。设计 以MCS- 51系列的的8052单片机为信息处理核心，辅以压力传感器、AD转换芯片、lcd显 示器等器件。并设计了各单元的硬件电路和控制软件，给出了相关电路原理图 、软件流程图、仿真或实物效果图。并对部件和功能进行了误差分析、功能检 验等。 关键词 智能秤；单片机；热量；健康； -I- Abstract With the rapid development of society and the enrichment of materials, however, the accompanying wealth disease has quietly eroded peoples body, so it is imperative to control the intake of high-calorie food reasonably. In view of the difficulty of intuitive understanding of heat, I completed the design of intelligent health scale in graduation design. This high level guides the design to enhance the ability to create a brilliant health designer with a unit computer like the Core.The design combines the knowledge of information detection, information transmission, information processing, single-chip computer technology and computer programming, realizes the function of weighing food under intelligent control, and can convert the calories of common food. It not only meets the basic requirements, has excellent accuracy and stability, but also achieves the function of heat conversion, which is closer to life, and does not require more cost investment. Its a new way of thinking about developing the electronic scale. The 8052 single-chip computer of MCS-51 series is designed as the information processing core, supplemented by p
