Microwave R D and production facilities in various regions at home and abroad, in order to meet the needs of consumer microwave ovens, various advanced modern technology used for microwave ovens, launched a series of new advanced microwave products. Subject design is based on a Mitsubishi FX2N series PLC intelligent control system for a microwave oven, FX only with programming simple, versatile, strong anti-jamming capability, high reliability and easy operation and maintenance, design, construction and commissioning period is short. This article according to the control requirements of intelligent microwave oven control system to determine the design of PLC intelligent control system based on the microwave oven; PLC completed the design of the main and auxiliary circuits; prepare the corresponding ladder, a key issue in the familiar system design after working principle of the microwave oven, the use of PLC programmable good, fast signal processing and control, aided by the keyboard input module, door stopper and sensor module composed of the control system, the completion of three cooking modes, three kinds of timing, completion reminders and ultra-high temperature alarm. Used in this design to the main software GX developer and GT designer3, where GX developer is us
