Car Calendar Clock and Temperature Measurement System

以AT89S52单片机为核心,设计一种智能车载日历时钟及温度测量系统.系统主要包括日历时钟、温度检测、按键、显示等部分.系统采用时钟电路芯片实现时钟的实时显示功能,并采用温度传感器实现环境温度的采集和A/D信号的转换,再通过单片机将其送入数码管进行显示.利用Proteus和Keil软件对系统进行仿真,结果表明该系统可实现预期功能.与传统的温度测量系统相比,该系统能够快速检测并反映在数码管上,测量精度高(测量精度为±0.5℃)且读数方便,具有很强的实用性和通用性.

An intelligent car calendar clock and temperature measurement system based on AT89S52 microcontroller is designed.The system mainly included calendar clock,temperature detection,key,display and other parts.The system realized the real-time display function of clock by using clock circuit chip,and realized the collection of environment temperature and the conversion of A/D signal by using temperature sensor.Then it was sent to the digital tube for display by single chip microcomputer.The system was simulated by Proteus and Keil,and the results shown that the system could achieved the expected functions.Compared with the traditional temperature measurement system,this system could detect and reflect on the digital tube quickly,and the measurement accuracy was±0.5℃and convenient reading.It has strong practicability and generality.
