Method for driving and controlling universal rotary magnetic field of the medical treatment miniature robot in the body
InactiveCN101262198ARealize drive controlEasy drive controlElectronic commutation motor controlAC motor controlDriving currentHelmholtz coil
The invention pertains to the technical field of medical engineering and discloses a method for driving and controlling a universally rotating magnetic field of a medical micro-robot in a human body. The method is characterized in that three groups of Helmholtz coils on z, y and x axes are arranged by orthogonal nesting so as to ensure that respective combined inductance is equal and the amplitude of intensity of magnetization of a harmonic magnetic field generated respectively is equal when the three groups of coils are driven by the same harmonic current. The relevant amplitude of an axis azimuth angle of the robot and a same frequency sine harmonic driving current of a phase are overlapped to form a spatial universally and evenly revolving magnetic field corresponding to the revolving axis of the azimuth angle in a certain space surrounded by the orthogonal Helmholtz coils on the three axes. The self-rotating direction of the universally rotating magnetic field can be changed by changing the current frequency to adjust the revolution of the magnetic field and changing the orthogonal Helmholtz coils on the three axes to drive the current direction. The method of the invention has the beneficial effects that the method is applicable to a bending inner environment of the human body and can realize a plurality of functions of rotation, going forward and backward and speed adjusting, etc., of the robot in the human body, and the positioning operation in the human body.

The control method comprises the steps of during the pre-charging period of a sub-module direct-current capacitor of the converter, the sub-module controller or the uniform controller automatically controls the power of a load resistor at the output side of the power-taking power supply according to the capacitor voltage to adjust the direct-current capacitor voltage of each sub-module, sothat the balance of the direct-current capacitor voltage of the sub-module during the pre-charging period is realized, and the successful pre-charging of the system is ensured. The voltage-sharing circuit is configured on the low-voltage output side of the power-taking power supply, and is simple in circuit, convenient to control, low in cost, free of participation of a master controller and wider in application range. After the sub-modules are pre-charged and enter an operation state, the voltage-sharing circuit stops working, so that the loss is reduced.

The invention discloses a pruning shear head used for a vehicle-mounted pruning machine for dwarf dense planting jujube trees. The pruning shear head used for the vehicle-mounted pruning machine for the dwarf dense planting jujube trees comprises an electric pruning tool, a mechanical arm, a front-back rough adjustment mechanism and a fine tuning mechanisms, wherein the mechanical arm is arranged on a bearing vehicle body; the front-back coarse rough adjustment is used for driving the electric pruning tool to swing front and back; the fine adjustment mechanisms are used for finely adjusting the laying position of the electric pruning tool; and the front-back rough adjustment mechanism is arranged at the front end of the mechanical arm in the manner of hinge joint. The electric pruning tool comprises pruning shears and a tool driving device used for driving the pruning shears to do continuous rotation; the tool driving device and the pruning shears are in transmission connection through a transmission mechanism I; the fine tuning mechanisms and the tool driving device are in the transmission connection through a transmission mechanism II; the tool driving device is arranged on the front-back rough adjustment mechanism; and the fine tuning mechanisms are arranged on the front-back rough adjustment mechanism. The pruning shear head used for the vehicle-mounted pruning machine for the dwarf dense planting jujube trees is simple in structure, simple and convenient in use and operation, high in tool adjustment speed, good in tool adjustment effect and high in practical value, and various problems of traditional jujube tree pruning equipment can be effectively solved.
