Provided is a full-automatic puncture needle developing enhancing method based on pattern recognition. The method comprises the following steps that an ultrasonic probe scans a part to be detected in a vertical mode, and a first ultrasonic image is formed; a puncture needle conducts puncture on the part to be detected at any angle; a puncture angle A of the puncture needle is recognized in a pattern recognition mode; a mainframe controls delay of an array element sound beam of the ultrasonic probe to enable the array element sound beam of the ultrasonic probe to deflect from the vertical direction at a deflection angle B and scan back and forth nearby; a second ultrasonic image taking the puncture needle as the principal thing is formed; a complete ultrasonic image is composited by the first ultrasonic image and the second ultrasonic image. The puncture needle is inserted at any angle, the puncture angle of the puncture needle is automatically obtained through the pattern recognition, the deflection angle B does not need to be preset, and puncture needle developing enhancement is achieved in a full-automatic mode; the deflection angle B of the array element sound beam is calculated out according to the puncture angle A, and deflection does not exist, so that the clearer second ultrasonic image is formed, and the whole puncturing and scanning work is more simple and convenient.

The invention provides a control device and a washing machine. The control device comprises a circuit board, a control panel, a frequency conversion chip and a driving module, wherein the control panel comprises a display control module arranged on the circuit board and a control switch connected with the display control module, and the display control module is used for sending an operation instruction to the frequency conversion chip according to the operation state of the control switch; the frequency conversion chip is arranged on the circuit board and is used for receiving and storing a motor control algorithm and a washing machine control program and generating a corresponding motor frequency conversion signal and a control instruction according to the operation instruction; and thedriving module is arranged on the circuit board and is used for driving a motor according to the motor frequency conversion signal. By applying the technical scheme provided by the invention, the motor frequency conversion signal and the control instruction are directly generated by the frequency conversion chip, so that the communication process of mutual interaction between a main control chip and the frequency conversion chip in the prior art is reduced, the control delay is reduced, the control efficiency is improved, the production cost is reduced, and the competitiveness of the product is finally improved.
