摘要:在工业生产中,电流,电压,温度,压力,流量,流速,和主开关通常的控制参数。其中,所述的温度控制也越来越重要。在许多领域的工业生产中,需要各种人炉,热处理炉,在反应炉中的温度,检测和控制锅炉。采用单片机控制的温度控制不仅是方便,操作简单,灵活性大等优点,而且可以大大提高被控温度的技术指标,从而可大大提高产品的质量和数量。因此,单芯片的温度控制的问题,在工业生产中的控制问题是经常遇到的。
ontrol system specific indicators requirement is that the heater heating temperature adjustment range is 600 ℃ -1000 ℃, temperature control accuracy of less than 3 ℃, the system overshoot shall be less than 15 % Software shall be designed to be man-machine dialogue , taking into account the system control object furnace, is a big part of the delay and the temperature adjustment range is wider, so the system will not be required for the transition time .
Is a set of chip CPU, RAM, ROM, I / O interface and interrupt system in one of the devices, only needed for the power and the crystal can be achieved on the digital signal processing and control. The use of design MCS-51 series single-chip set 8051 -based controller, the temperature of the furnace intelligent control software designed to achieve the ultimate man-machine dialogue to achieve the furnace temperature control.
Design papers include: sampling, filtering , keyboard, LED display systems, heating control system , the MCS-51 microcontroller development and application software development. As a control system of a typical experimental design , microcontroller temperature control system integrated use of computer theory , automatic control theory , analog electronics, digital control technology , keyboard, display technology and many other aspects of knowledge, is the knowledge of a comprehensive test .
Actual MCU control engineering design learning basic skills . SCM trend is towards high integration, small size, large capacity, high speed , easy to use , high-performance direction. So I graduated from the design of this opportunity to further learn about the MCU control is necessary, and can further enhance their practical engineering skills.
Independent analysis and to improve the overall quality of solving engineering problems . Students must have a more comprehensive analysis of issues, problem-solving abilities . To learn more angles to seize the key technical issues and problems , independent analysis and solve engineering problems. Note that the learned knowledge can be effectively linked to mastery in the design process . To establish a correct view of security , economic point of view , the global point of view , we must strive to achieve from students to engineering and technical personnel of the transition and the changing role .
Cultivate serious, inquisitive , assiduously, pragmatic work style. Graduation contents, heavy task, computationally intensive , to develop serious, inquisitive , meticulous and realistic style of work , promote innovation, unity and cooperation fine style . Non- fiction data falsification and plagiarism achievements behavior. Threw himself into the design , the timely completion of the design task.
