摘要
在该设计中,数字钟及各项功能由一片主单片集(89C52)和DSI2887实现。能准确显示年、月、日、时、分、秒、星期。另外其他附加功能,如:温度、电网频率、电压、电流监测机功率、功率因数由另一片单片机实现,检测数据串行传送到主单片机;主单片机完成欠压,过压报警及显示功能;非接触止闹功能采用无线遥控方式实现。
In this paper. the function of timing is realized by DS12C887 and 89C52, it can display hour, minute. second, year. month. day etc. It can also measure temperature, voltage. current. power and frequency etc by the other one 89C52, then the latter send the data to the master MCU by serial communication. The master MCU can give an alarm when needed. it can stop alarming by remote control.
