2、perature control system is widely used in the field ofindustrial control, such as boiler steel plant, machinery plant, the temperature control system in thermal power plant. Relay control technology is widely used in hea

3、ting furnace of electric control system of the traditional, due to realize logic control with fixed wiring of hardware, the control system to increase in size, power consumption, efficiency is not high and is susceptible

4、 to failure, can not guarantee to produce normal industry, with the development of computer control technology, the traditional relay control technology must be based on computer the PLC control technology to replace. Th

5、e temperature of the heating furnace is a large inertia system, using PID control, with the expanding of PLC function in many PLC controllers has been expanded PID control function, and the excellent performance of the P

6、LC PLC control of the temperature control system of economic performance is stable and convenient maintenance based on. The design of programmable controller, the control system of heat treatment furnace temperature by u

7、se of Mitsubishi FX2N.The PLC temperature control system, introduces the design processof hardware and software and Mitsubishi FX2N system based on A/D, including the design of conversion, temperature detection, integral

8、 separation PID algorithm and zero digital trigger circuit. The heating furnace temperature sensor into voltage signal into voltage signal, PLC main control system within the A/D will be brought into the digital quantity

9、 can be identified by PLC, then under constant temperature deviations from the actual temperature of the E (k) according to the integral separation PID control algorithm, get the output control quantity of U (k), output

10、value after D/A conversion from analog output voltage regulation at both ends of the resistance wire heating furnace, voltage, temperature of the temperature of the heating furnace to achieve the target value.Keywords: P
