摘　　要：介绍一种以单片机为核心的温度采集控制电路的开发与应用,该系统采用DS18B20传感器作为多点检测,并将检测到的信息传送到AT89S52进行信息分析与处理,最终通过显示器1602LCD显示出来.根据需要设置温度上、下限,超出温度范围通过LED指示灯异常报警,从而达到对多点温度的实时监控与报警的功能,大大提高了控制技术在生产和生活中的应用.Study and application of single-chip as the core of control circuit of temperature acquisition is introduced,and this system uses DS18B20 sensors as multipoint detection,and utilizes the detecting information transmitted to AT89S52 information to analysis and manage.Finally,it is displayed through the display 1602LCD.The upper and lower limits of temperature are determined as needed,and abnormal alarm is sent to the LED indicator when the temperature exceeds the temperature range,so as to achieve the function of real-time monitoring and alarm of multipoint temperature.The application of control technology in production and life has been greatly improved.
