LIANG Jian-hua;Linfen Vocational and Technical College Electromechanical Department;
At present, temperature control is involved in most equipment of industrial enterprises, and the quality of automatic temperature control directly affects the quality of the producer and the benefit of the enterprise. In the actual production, because of the different characteristics of temperature-controlled components, the temperature control accuracy is low and the adjustment time is long. In this paper, a better temperature control system is introduced, which takes AT89C52 as the core, introduces negative feedback correction network, adopts PID algorithm to control, combines temperature sensor, A/D conversion circuit, digital tube display and other hardware circuits, and finally realizes automatic temperature control. The system has the advantages of simple circuit design and high precision.
