MCU-Based Electric Heating Furnace Temperature Control System Design
Abstract:With the development of the technology of computer and control,the temperature control of electric heating furnace is becoming fully developed, the technology has been an important part of industry.
The design of microcontroller-based temperature control system for electric heating furnace, by controlling the voltage resistance wire at both ends of the working hours to control the average power output resistance wire, electric heating furnace in order to achieve automatic control of temperature. System is divided into temperature measurement, A / D conversion, single-chip system, the keyboard system, temperature display circuit, alarm circuit, D / A converter such as a number of functional modules. The system has hardware and low cost, high temperature control accuracy, reliability, and features such as anti-interference ability.
