摘 要 随着时代的进步和发展，温度的测试已经影响到我们的生活、工作、科研、各个领域，已经成为了一种非常重要的事情，因此设计一个温度测试的系统势在必行。 本文主要介绍了一个基于AT89C51单片机的数字温度报警器系统。详细描述了利用数字温度传感器DS18B20开发测温系统的过程，重点对传感器在单片机下的硬件连接，软件编程以及各模块系统流程进行了详尽分析，对各部分的电路也一一进行了介绍，该系统可以方便的实现温度的采集和报警，并可以根据需要任意设定报警上下限温度，它使用起来相当方便，具有精度高、量程宽、灵敏度高、体积小、功耗低等优点，适合于我们日常生活和工、农业生产中的温度测量，也可以当做温度处理模块潜入其他系统中，作为其他主系统的辅助扩展。DS18B20与AT89C52结合实现最简温度报警系统，该系统结构简单，抗干扰能力强，适合于恶劣环境下进行现场温度测量，有广泛的应用前景。 关键词：单片机；温度检测；AT89C51；DS18B20 Abstract With the predevelopment of the times, the temperature of the test has affected our lives, work and research in various fields, has become a very important thing, so the design of at temperature measurement systems s imperative. This paper describes the digital temperatures based on AT89C51 micro controller. Detailed description of the use of digital temperature sensor DS18B20 temperature measurement system development process, focusing on the sensor hardware in the micro controller is connected, software programming, and each module processes carried out a detailed analysis oft he various parts of the circuit were introduced one by one, the system can easily achieve the temperature collection and alarm, and the alarm can be any upper and lower temperature according to need, it is very convenient to use, with high accuracy, wide range, high sensitivity, small size, low power consumption, suitable for our daily life and industrial and agricultural production temperature measurement, temperature processing module can also be used as sneak other systems, other main system as an auxiliary expansion.DS18B20withAT89C51combinedto achieve the most simple temperature alarm system, which is simple structure, strong anti-jamming capability, suitable for in-situ temperature measurements in harsh environments, there is a wide range of applications.
