摘要
系统以AT89C51单片机为控制核心,利用新型一线制温度传感器DS18B20测量温度值,实现粮仓环境温度的检测和报警。本文给出了由AT89C51单片机和DS18B20构成的单总线温度测量系统的硬件电路及软件流程图。该系统具有测点多、精度高、速度快、稳定性好、报警及时等特点,也可应用于其它相关的温度控制系统,通用性较强。
The system for the control of the core is AT89C51,the temperature sensors DS18B20 is used to measure temperature and this system can realize ambient temperature measurement and alarm. This article introduces the hardware circuit which the software flow chart constitutes by AT89C51 monolithic integrated circuit and DS18B20. This system has many measuring point, high-precision, wide range of temperature monitoring, good stability and alarms timely, it may also be applied in other related temperature control system and the versatility is strong.
