An ultrasonic welding power supply based on dual processor control of DSP and ARM9 is designed in this paper,whose hardware composition and software design process are introduced. The peripheral working state and welding procedure process of the ultrasonic welding power supply are controlled with the DSP controller. The human-machine interface control system based on Linux system is designed by means of ARM9 controller. The data sharing of dual processors is realized by means of the dual-port RAM technology,which ensures the fast,real-time and reliable transmission of data such as process parameters and status information of the ultrasonic welding power supply,so as to meet the needs of users for large amount of data processing such as remote monitoring and fault diagnosis of the ultrasonic welding power supply. The testing platform of ultrasonic metal welding was built for welding test. The experiment results show that the developed ultrasonic power supply has a good human-computer interaction performance and welding effect.
