This paper describes the software /hardware frame for a coordinated range hood and gas cooker using TMS320F28035 as the main control chip,MSP430G2553 as the trigger chip and NRF24L01 wireless communication module to realize automatic speed regulation, noise reduction and maximal energy saving for the range hood. The range hood is driven by a sinusoidal wave BLDC. Wireless communication is realized between the range hood and gas cooker,with the output rotation speed being synchronous with the fire power. BLDC control adopts IPM,the software adopts sinusoidal wave control,and SVPWM drive is used in this device. The BLDC rotor is positioned through software simulation,and advance commutation angle is added to obtain maximal output torque through minimal current value. The test result shows that high efficiency and low operational cost is achieved in the intelligent device. It has a good market prospective in the intelligent kitchen application and lays a solid foundation for low-cost application.
