PAGE PAGE 15 摘 要 随着现代工农业技术的发展及人们对生活环境要求的提高，温度已占据了人们生活中的重要位置，已经被广泛应用到各个领域中去。传感器与单片机相结合,使之不仅具有检测功能，还具有信息处理、逻辑判断、自诊断等人工智能,对信息处理自动化及科学技术进步起着非常重要的作用。 本文介绍的智能数字式温度测量报警系统是由温度传感器采集温度信号并转换成模拟信号，在由A/D转换器把模拟信号转化成数字信号后送入单片机输入端。单片机根据输入端接收到的数字信号，通过软件编程，将数字信号由数码管显示器显示出来。由键盘设置温度上下限，当温度超过设置的上下限温度值时报警。 关键词：传感器 单片机 数码管 Abstract Along with modern industry and agriculture technology development and people to living conditions request enhancement, The temperature occupied the people to live the important position, Widely was already applied in each domain. Spread the feeling machine and a machines combine together, making it not only had the function of examination, but also had the information processing, logic judgment, from examine a patient etc. artificial intelligence, automate to the information processing and science technique progress rise count for much function. This article introduced the intelligence digital temperature survey alarm system is and transforms the simulated signal by the temperature sensor gathering temperature signal, In transforms after the A/D switch the simulated signal the digitalsignal to send in the monolithic integrated circuit input end. Monolithic integrated circuit digital signal which receives according to the input termination, Through software procedure which composes beforehand, Demonstrates the digital signal by the nixietube monitor. By keyboard establishment temperature bound, when the temperature surpasses the establishment the bound temperature value reports to the police.
