Development Of Electronic Massager Based On Chaotic Circuit Control

With the development of economy,aging population is increasing,and more and more people need some physical therapy to keep fit.massage as traditional Chinese medicine therapy can be accepted by the elderly,and modern technology integration into traditional massage has become a trend.The electronic massaging instrument based on chaotic circuit control has the characteristics of chaotic system with the inherent randomness in the deterministic system,which can overcome the adaptability of human muscle to stimulation.based on the characteristics of chaotic systems,chaotic systems in many chose three typical chaotic systems in Simulink dynamic simulation,by adjusting the module parameters,get three chaos phase diagram of the system.According to the obtained dynamic simulation images and the difficulty of the circuit,the circuit simulation of CAI's circuit and Duffing chaotic circuit is selected,and the Duffing chaotic system is finally used as the control signal of the massage instrument.According to the schematic diagram of circuit simulation,the device selection of chaotic circuit is made.Select STM32F103VCT6 as the processor chip of massager,design the minimum system,key circuit,display circuit and power circuit and other peripheral circuit,and get the appropriate output signal.The vibration circuit is designed according to the parameters of the output signal and the vibration motor of the laminated plate,and finally the whole circuit design of the massager is finished.Use the standard external library,the reference routine for the software required for the massage instrument.This paper includes the processing of signals generated by chaotic circuit,selection of massage mode,control of output signal amplitude and massage time,and display of human-computer interaction interface.Finally,the software and hardware components are debugged to complete the development of electronic massager based on chaotic circuit control.
