摘 要
随着经济社会的协调发展，城市居民的生活得到了很大的改善，消费结构出现了新的亮点，对于生活自动化的要求也更加迫切，而且越来越多的家庭主妇都需要学习做菜，传统的菜谱一般式纸质的，或是上网打印或是到书店买本菜谱，但是纸质的菜谱在厨房很容易弄脏弄湿，而且要换新的菜谱就又必须重新下载或者买一本菜谱，非常不方便。
而无烟锅锅柄上植入电子菜谱的方案将会大大提高菜谱的便携程度,提高人们的生活质量。本文从硬件软件方面设计和研究，包括如何将菜谱从PC机导入无烟锅手柄中，锅手柄上的液晶显示和低功耗，耐高温等。这种集成了电子菜谱的无烟锅远比买一个无烟锅与独立的电子菜谱便宜，在价格上有它的优势，加上它的健康与便捷，在数字化消费电子产品市场看好和无烟锅被人认可与广泛使用的今天，具有显著地经济效益和社会效益。

Abstract
With the coordination of economic and social development, urban life has been greatly improved, the consumption structure of a new bright spot for the automation of life and more urgent, and a growing number of housewives who have to learn cooking,
Traditional recipes are generally paper-based, to print online or to buy the recipe book . However, paper-based recipes in the kitchen can easily wet and dirty . It is very inconvenient to re-download or buy a new cookbook for changing the manu. smokeless pots’panhandle implanted E-cookbook which will be greatly improved portable of the recipe, and increase the quality of people''s lives! In this paper, we design and research from the aspects of,hardware and software ,including how to import the recipes from the PC to smokeless pots’panhandle, the the liquid crystal display of smokeless pots’panhandle and low-power, high temperature and so on..These smokeless pots which integrate with E-cookbook much cheap than buying a smokeless pot or independent E-cookbook . Because of it’s low price ,healthy and convenient. It have economic and social benefits significantly in the digital consumer electronics market nowdays.
Keywords：E-cookbook ，Single-chip，portable ，smokeless pots’panhandle
