Abstract
Multi-functional clock get ready system abandon whom tradition ring bell tedious , instead of modernization beautiful , pleasant environmental music, let student immerse in beauty of the music in each ring tones , experience the glamour of the music, form the joyful mental state . Not only activate students' artistic cell but also reach and optimize and educate people's environment, mould the result of student's sentiment. Advance quality-oriented education virtually, build the good campus atmosphere. The school and some enterprises and institutions use this system as going to school and leave school , signal of the daily schedule on and off duty ,etc. extensively.
Multi-functional clock get ready system adopt AT89C51 one-chip computer control as key device peripheral component realize multi-functional intelligence get ready, namely realize sounding the bell in many kinds of situations at the moment of establishing a lot of kind. System this working course to spend AT89C51 one-chip computer read clock chip DS1302 and get ready time compare with with whom EEPROM set for, get ready constantly identical with establish , control the chip loud bell of music through AT89C51. In addition should systematic to set up keyboard and LCD show , can realize to establishment to get ready the moment also, the data set up will be kept in EEPROM. Because that adopted is EEPROM this system can still keep the data set up in advance while losing the electricity, and keep already existing loud bell time.
