| Designing and simulating Virtual Intelligent of Bio-electromagnetic field, and completing the control system hardware production. Details are as follows:The dissertation designed the Bio-electromagnetic device. By using switching power supply technology, DC power and AC power required for constant and static magnetic field is designed, so as alternating electric fields and transient magnetic field. The simulation results are:the regulator rectifier filter circuit output is50V-250V DC to achieve adjustable power; boost-PFC doubles the output voltage of the rectifier filter circuit and improve the power factor; DC output of Phase-shifted full-bridge ZVS-PWM circuit is200V-1000V, it is precise and adjustable. AC output frequency is30kHz, the amplitude is200V-1000V, it is precise adjustable. Bio-power electromagnetic devices the article designed meet the requirements.Then the dissertation designed the power control system of production and hardware of electromagnetic. By using DSP to achieve closed-loop power control, it fulfils the manifestation of intelligent devices. By simulating double-loop digital control of PFC based on PID algorithm, the results show the impact of KP, KI and KD for the PID algorithm. Using algorithm to generate5-way PWM wave and giving the relevant program flow. The paper designs hardware of control drive circuit.The article builds the model of biological field strength and simulates on matlab. Using Ansoft analysis software to simulate the electrostatic field, alternating electric field and constant magnetic field. The simulation results are:electrostatic field strength is proportional to the source voltage and inversely proportional to the height of the signal; Alternating electric field with sinusoidal excitation sinusoidal variation; Constant magnetic field is proportional to current and copper coil turns. Rotating magnetic field changes over time. Device meets the designing requirements.At last, the paper designed virtual interface. By using LabVIEW, the login interface, serial communication debugging interface and status monitoring interface and data storage query interface are designed. The interface design is based on status monitoring interface and data storage is user-friendly and practical.In summary, through designing and simulating the power of the device and the radiation device,the dissertation completes the design and implementation of intelligent virtual device. |
