基于单片机的电饭锅控制系统的设计

潍坊科技学院本科生毕业设计（论文）AbstractWith the progress of science and technology,electric rice cookers areconstantly updated.This design is mainly based on the current situation of thedevelopment of the electric rice cooker products,taking simplicity,convenienceand humanization as the design concept,to realize the control of the timingfunction,heating function,heat preservation function,display function,etc.of theelectric rice cooker.The whole design is divided into hardware design and software design.Thehardware design part is based on single chip microcomputer as the core controldevice and DS18B20 as the temperature detection device,including clock circuit,reset circuit,heating disk circuit,display circuit,touch key circuit,relay controlcircuit and switching power supply.In the software design part,C language isselected to realize the control of time timing,temperature display,heating andheat preservation of the system,including main program and key subprogram,display subprogram,heating subprogram,heat preservation subprogram,clocksubprogram,acquisition subprogram and protection subprogram.Key Words:STC89C51 single chip microcomputer;DS18B20 temperaturesensor;Timing.川-
