基于单片机的可控加热器设计 温度是工业中非常关键的一项物理量，在农业、工业、各种高新技术的开发和研究中也是一个非常普遍和常用的测量参数。目前，随着信息技术的发展，传感技术的广泛应用，温度测试技术已向自动化、智能化方向发展。基于此，提出了温度的数字化测量。? 随着人们生活水平的不断提高，数字温度计的要求也越来越高，为现代人工作、科研、生活、提供更好、更方便的设施就需要从新技术入手，一切向着数字化控制、智能化控制方向发展。本设计需要采用传感器技术与电子技术相结合。设计的数字温度计与传统的温度计相比，输出温度采用数字显示，具有读数方便，测温范围广，测温准确等重要特点。 单片微型计算机是随着超大规模集成电路技术的发展而诞生的，由于它具有体积小、功能强、性价比高等特点，所以广泛应用于电子仪表、家用电器、节能装置、军事装置、机器人、工业控制等诸多领域，使产品小型化、智能化，既提高了产品的功能和质量，又降低了成本，简化了设计DS18B20；MOC3061；PID Based on MCU controllable heater design ABSTRACT The temperature is very key industrial a physical quantities, in agriculture, industry, all kinds of high and new technology development and research is also a very common and common measuring parameters. Now, along with the development of information technology, sensing technology application, temperature testing technology has to automation, intelligent direction. Based on this, puts forward the digital measurement temperature. As people living standard rise ceaselessly, the digital thermometer and higher demand for modern job, scientific research, life and provide better and more convenient facilities will need all of new technology, digital control and intelligent control towards direction. This design need to adopt the sensor technology and electronic technology combined. Designed digital thermometer, compared with traditional thermometer USES digital output, according to temperature, temperature readings convenient with accurate temperature measuring range, such important characteristics. The single chip computer is with very large scale integrated circuit technology development and the birth of, because it has a small volume and powerful function, high performance-cost ratio, so widely used in electronic instrument, household appliances, energy-saving equipment, military equipment, robots, industrial control and so on many domains, make the product miniaturization, intelligent, not only improves the function of products and quality and lower cost, simplified the design.
