1、Abstract摘要数字电子时钟是人们日常生活中不可或缺的必需品。电子钟主要是利用现代电子技术将时钟电子化、数字化。与传统的机械钟相比,具有时钟精确、显示直观、无机械传动装置等优点,因而得到广泛应用。另外,在生活和工农业生产中,人们对电子钟的功能又提出了诸多要求:报时、闹钟、日历、温度显示,这就需要电子时钟的多功能性。根据人们的不同要求,本设计主要为实现一款可正常显示时钟,测量环境温度、湿度,带有定时闹铃,倒计时的多功能电子时钟。本设计采用液晶显示以其亮度高、显示直观等优点被广泛应用于智能仪器及家用电器等领域。该时钟系统主要由时钟模块、闹钟模块、环境温度湿度检测模块、液晶显示模块、
2、键盘控制模块以及信号提示模块组成。能够准确显示时间(显示格式为时时:分分:秒秒,24小时制),可随时进行时间调整,具有闹钟时间设置、闹钟开/关、止闹功能,能够对时钟所在的环境温度进行测量并显示。设计以硬件软件化为指导思想,充分发挥单片机功能,大部分功能通过软件编程来实现,电路简单明了,系统稳定性高。关键词:电子时钟;单片机;多功能;温湿度传感器3AbstractIAbstractAbstractDigitalelectronicclockisindispensabletodailylife.Electronicclockistheuseofmodernelectronictechn
