Design of Temperature Controller Based on ARM

Abstract:Accurate temperature control has always been in the industrial production and human life which occupies a very important role, the temperature of the intelligent control of the direct impact of industrial production control effect, temperature control is almost in any field applications, but the control accuracy and intelligence level Is not high, this paper based on the above problems designed a ARM-based temperature controller design to meet the needs of modern intelligent control applications.

  This paper introduces the research status of intelligent temperature control at home and abroad, and then introduces the knowledge of temperature sensor and temperature acquisition principle, liquid crystal and expert PID algorithm, and then analyzes and understand its function and demand. The overall hardware and software related knowledge of the system were introduced separately, the hardware platform was built on the intelligent temperature control experiment, and finally through the human-computer interaction interface real-time observation of the current temperature working state, is in the non-working state, heating State or cooling state, you can adjust the temperature range by pressing the key. From the final experimental results can be seen that the control system can achieve intelligent control of temperature, can be applied to industrial production.

Keywords: human-computer interaction, expert PID, intelligent control, temperature
