摘要
采用STC89C51单片机作为主控制芯片,计了一款带有闹钟并具有语音唤醒功能的智能家用唤醒系统。此系统采用时钟芯片DS1302记录日期和时间信号,DS18B20温度传感器作为温度采集模块,LCD12864字符液晶显示器作为显示模块,利用PWM波调节唤醒灯亮度,ISD1760语音模块播报当前温度和穿衣建议,通过按键设置具体的时间和日期及闹钟等。本系统通过单片机控制,可在设定闹钟的时间到达之前启动唤醒灯,待唤醒灯亮度最大时闹钟开始响起,并且语音提醒温度和时间等信息。这款设计有一定的可行性和人性化等特点,不仅可以用在满足普通人的唤醒需求,又可以用于老年人以及有耳疾的残疾人的唤醒需求等场合,在一定程度上体现了智能化。
An intelligent home wake-up system with the function of alarm clock is designed ba-sed on MCU STC89 C51 chip.STC89 C51 micro-controller is used as the main control chip. D-S1302 is used to record the date and time signals, and DS18 B20 is adopted as the temperature acquisition modula.LCD12864 is used as a display module, and PWM is used t-o change the lamp brightness. ISD1760 voice module is used to broadcast the current tem-perature and give wearing suggestions. The alarm time can be set by button. The wakeup la-mp works before the setting time, and the alarm clock starts to ring when the lamp reac-hes its maximum. Meanwhile, the temperature and time are broadcast. The system can b-e used for ordinary people and some disabled people with ear diseases, which reflects t-he intelligence in some extent.
