【Abstract】 A novel intelligent and fully automatic control system for an electric boiler is described and the working principles, hardware structure and software flow path of the system are presented. The control system adopts AT89C52 in the single chip processor series of ATMEL Co. to serve as a central processing unit and has selected the microcomputer monitoring circuits and watchdog technology of MAXIM Co. A ferroelectric memory FM1608S is employed to store the parameters set by an end user and a solid state relay used to serve as a switching device. An original and novel single line intelligent digit temperature sensor DS1820 serves as a temperature measuring element, which can attain a temperature measruing precision of 0.5℃. This type of digital sensor can be connected directly to a single chip processor with no need for other circuits. The single chip processor based fuzzy detection and control system under discussion consists of a two dimensional fuzzy control device. A construction drawing of the fuzzy controller system is given along with a fuzzy control rules base table and a fuzzy control table. Practical use experience of the control system has demonstrated its excellent measurement and control effectiveness with the in door temperature being controlled to a precision level of ±1℃.更多还原
