2、用在很大程度上提高了冷藏运输中对温度的控制水平。本设计论述了一种以 AT89C51 单片机为主控制单元,以 DS18B20 为温度传感器的温度测量系统。该测量系统可以实时 存储相关的温度数据。系统设计了相关的硬件电路和相关应用程序。 关键词: 温度测量 冷藏运输车 AT89C51 DS18B20 Abstract Along with the development of science and technology, peoples demand for the quality of frozen food is increasingly improved. So the extension
3、 of Highway Refrigerated Transport has also developed. Measuring temperature is the most important in refrigerated transport. Transport temperature is the key factor to affect the quality of products. If the temperature is too high, it will make the product aging; temperature is too low, may make th
4、e product easy to freeze. In addition, in the transport process, temperature fluctuations in large or frequently to maintain product quality disadvantage.N owadays, the computer measurement and control technology develop rapidly and widely applicable. based on singlechip temperature gathering and co
5、ntrol system development and application greatly improve the production of temperature in refrigerated transport . This design AT89C51 describes a kind of mainly by MCU control unit, for temperature sensor DS18B20 temperature measurement system. The measurement system can real-time storage temperature data. System design related hardware circuit and related applications.
