In recent years in industrial intelligent instrumentation, optical equipment, automatic detection, information processing, remote munication monitoring, intelligent building automation, household appliances, etc widely application and rapid development. MCU application breadth and depth has bee a measure of an important symbol of a country39。s industrial development. Experts predicted: puter application field of the most important after the PC era based on single chip microputer technology to develop embedded system. Electric rice cooker, this dissertation mainly studies 51 under the control of microcontroller, intelligent operation used to realize electric rice cooker. The design of the main application of electronic circuit design and circuit board production technology, SCM operation instruction system and function to achieve, finally realizes the electric rice cooker cooking process under the control of single chip microputer. Embedded appliances not only save the kitchen space, and can make all kinds of electrical appliances between arrangement more reasonable and practical, and realize the kitchen space of maximum utilization and the people the convenience of operation, for people now living the life requirement of highend, atmosphere and grade. The application of embedded system in rice cooker makes it easier to rice cooker brings great convenience to people39。s life.
