乳粉干燥微机控制系统 ——基于51单片机温度控制系统 摘 要 温度是日常生活中无时不在的物理量，温度的控制在各个领域都有积极的意义。本文以喷雾干燥塔作为系统的控制对象,选用空气温度为控制量,以控制旁路冷风为控制手段,从硬件和软件两方面阐述了系统的设计思想和实施过程。为提高干燥奶粉的品质奠定了基础。采用单片机对它们进行控制不仅具有控制方便、简单、灵活性大等特点，而且还可以大幅度提高被控温度的技术指标，从而能够大大提高产品的质量。因此，智能化温度控制技术正被广泛地采用。 本温度设计采用现在流行的AT89S51单片机，配以DS18B20数字温度传感器，通过AT89S51单片机处理并在数码管上显示，并且对空气温度进行实时控制，达到乳粉干燥所需要的温度。 关键词：温度；奶粉干燥；单片机；传感器 Dried milk powder computer control system --based on the 51-series computer temperature control system Name: Wang Dongsan Major: Electronic Information Science and Technology Tutor: Gao Guoli Abstract The temperature is constantly in the daily life of physical and temperature controls in various fields have a positive meaning. Dryer control is an important means to guarantee the quality of drying materials and to improve the drying efficiency. In this paper, the spraying and drying tower was used as the system control plant, and compared the measures for spray dryer control, and the temperature of air discharge was used as the control volume. It was the control method by controlling the volume of wind. The design and implementation of the system were given a minute description of hardware and software. All of these would establish a solid foundation to improve the quality of spray dryer products. SCM using their right to control not only easy to control, simple, such as the characteristics of flexibility, but can also significantly increase the temperature was charged with the technical indicators, which can greatly enhance the quality of the products. Therefore, intelligent temperature control technology is being widely adopted. The temperature was designed with the now popular AT89S51 SCM, and with DS18B20 digital temperature sensor, The temperature sensor can set up their own temperature collars. SCM will detect that the temperature of the input signal and temperature, the lower comparisons this judgment whether to activate the relay to open the equ
