Time switch ringing the bell can be used in factories, schools and so on need to regular the occasion of ringing the bell. Time switch the use of ringing the bell can achieve energy saving, safety, convenience, etc. This paper introduces a kind of based on STC89C52RC single-chip microcomputer timer switch design of ringing the bell.This article first describes the functions to be achieved by the automatic bell system design,and then expounds design and principle of the circuit system, including design scheme selection, key components, circuit design specificSTCion (including power circuit, keyboard, 1602 single chip microcomputer control circuit, liquid crystal display, relay circuit) software design process, and system test. Finally, I made a summary of the graduation project.Keywords: STC89C52RC;Timer switch;LCD 1602...
