| With the continuous deepening of research on diversified treatment methods,the pulse therapy instrument is widely used as an effective treatment and health care electrical stimulation device.Its characteristics of safety,reliability,non-invasiveness and high efficiency have attracted widespread attention.Headache is a common disease.Electrical stimulation is used to treat headaches.Electrical pulses are input to the human head through the scalp to stimulate certain changes in certain factors of the head,which can regulate the functions of various parts and effectively treat headache symptoms.Massage,health care and other functions.At present,many pulse treatment devices on the market have the disadvantages of poor treatment specificity,poor treatment effect,and low electrode contact efficiency.Therefore,the development of an electric pulse therapy instrument for headache treatment with electric acupuncture has a very important role.In this paper,the research background and current situation at home and abroad study of this problem will be studied and analyzed,the principle of therapy treatment instrument theoretical research,compares and selects the way when the scalp needle acts on the head,and designs multiple steering gears and sensor combinations.Control the automatic loading method.Headache this study treatment,using Altera Corporation Cyclone IV Series FPGA chip as the main controller,using Verilog HDL language and the FPGA build NOIS Ⅱ system using DSP Builder tool and Matlab / Simulink design jointly developed DDS waveform generating module,the switch control module to complete the electrodes and a multiplexer gear control design.The last complete control circuit download and online tests,to complete the verification,as expected,proved the feasibility of the system design.After completing the prototype,each functional module is tested,and the experimental conclusions show that the treatment device designed for this project meets the treatment requirements,with a high degree of automation and easy operation. |
