摘要：基于AT89S51单片机开发了温度控制采集显示系统,着重介绍了系统核心硬件设计和软件设计.利用LM35温度传感器采集温度、经LM358放大10倍后输入到A/D采样电路,由TLC549将数字值传送给AT89S52单片机,最后由单片机驱动数码管显示温度.测试结果表明,在外部环境温度变化较大时该系统响应时间短,灵敏度较高,工作稳定可靠.
A temperature control acquisition and display system was developed based on Ar1＂89S51 single -chip microcomputer（SCM）. The core hardware design and software design were mainly discussed. The system uses LM35 temperature sensor to collect temperature. The acquisition temperature was input into the A/D sam- piing circuit by magnified 10 times through LM358, the digital value was passed to the AT89S51 SCM by TLC549 , and the digital tube was used to display temperature. Furthermore, the results demonstrate the system have short response time, high sensitivity, stable and reliable operation when large temperature changes in the external environment.
