Description

Technical Field

[0001] The invention relates to the field of single-phase asynchronous motors, and in particular to a dual single-phase asynchronous motor. Background Art

[0002] Asynchronous motors that use single-phase AC power are called single-phase asynchronous motors. Single-phase asynchronous motors are easy to use and widely used because they only require single-phase AC power. They also have the advantages of simple structure, low cost, low noise, and low interference to radio systems. Therefore, they are often used in low-power household appliances and small power machinery, such as electric fans, washing machines, refrigerators, air conditioners, range hoods, electric drills, medical equipment, small fans, and household water pumps. Since China's single-phase voltage is 220V, and foreign single-phase voltages such as 120V in the United States, 100V in Japan, and 230V in Germany, Britain, and France, when using foreign single-phase asynchronous motors, it is necessary to pay attention to whether the rated voltage of the motor is the same as the power supply voltage.

[0003] In actual use, due to the need for complete timing or excess power, two single-phase asynchronous motors can be used to coordinate power supply. However, the two coordinated single-phase asynchronous motors may come into contact due to their close distance. Once in contact, the vibration amplitude of each motor will double, increasing the instability and uncontrollability of the system. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a dual single-phase asynchronous motor, which can identify the image block occupied by the first single-phase asynchronous motor in the received tilt-corrected image as a reference image block, obtain the geometric shape of the edge of the reference image block, and when the acquired geometric shape is missing relative to the geometric shape of the reference shape pattern corresponding to the first single-phase asynchronous motor, obtain the depth of field value of the first single-phase asynchronous motor in the tilt-corrected image and the depth of field value of the second single-phase asynchronous motor in the tilt-corrected image, when the depth of field value of the first single-phase asynchronous motor in the tilt-corrected image and the depth of field value of the second single-phase asynchronous motor in the tilt-corrected image are When the difference in the depth of field values ​​in the corrected image is less than or equal to the set depth of field limit, it is determined that the first single-phase asynchronous motor is connected to the second single-phase asynchronous motor, otherwise, it is determined that the first single-phase asynchronous motor is not connected to the second single-phase asynchronous motor, thereby achieving effective distinction of the contact state of the first single-phase asynchronous motor and the second single-phase asynchronous motor, and also citing a voice playback mechanism for performing voice playback of vibration warning information corresponding to the connection between the first single-phase asynchronous motor and the second single-phase asynchronous motor when the first single-phase asynchronous motor and the second single-phase asynchronous motor are connected in customized visual analysis, thereby completing high-precision detection and warning of whether the motors working in coordination with the dual motors are in contact.

[0005] According to the present invention, a dual single-phase asynchronous motor is provided, comprising a first single-phase asynchronous motor body, a second single-phase asynchronous motor body and a scene analysis system, the system comprising: A visual shooting mechanism, for performing a visual shooting operation in the face of a dual-motor working scene to obtain and output a corresponding instant visual picture, wherein the dual-motor working scene contains a first single-phase asynchronous motor and a second single-phase asynchronous motor for collaboratively generating the same output power; A smoothing filter device, connected to the visual shooting mechanism, is used to perform edge-preserving smoothing filter processing on the received instant visual picture to obtain and output a corresponding smoothing filter image; A content sharpening device, connected to the smoothing filtering device, for performing a sharpening process based on a Kirsch operator on the received smoothing filtered image to obtain and output a corresponding content sharpened image; a tilt correction device connected to the content sharpening device, configured to perform a tilt correction process on the received content sharpened image to obtain and output a corresponding tilt corrected image; a missing judgment mechanism connected to the tilt correction device, used to identify the image block occupied by the first single-phase asynchronous motor in the received tilt correction image as a reference image block, obtain the geometric shape of the edge of the reference image block, and obtain the depth of field value of the first single-phase asynchronous motor in the tilt correction image and the depth of field value of the second single-phase asynchronous motor in the tilt correction image when the acquired geometric shape is missing relative to the geometric shape of the reference shape pattern corresponding to the first single-phase asynchronous motor, so as to determine that the first single-phase asynchronous motor is connected to the second single-phase asynchronous motor when the difference between the depth of field value of the first single-phase asynchronous motor in the tilt correction image and the depth of field value of the second single-phase asynchronous motor in the tilt correction image is less than or equal to the set depth of field limit, otherwise, determine that the first single-phase asynchronous motor is not connected to the second single-phase asynchronous motor; A voice playing mechanism, connected to the missing judgment mechanism, is used to perform voice playing of vibration warning information corresponding to the connection between the first single-phase asynchronous motor and the second single-phase asynchronous motor when it is determined that the first single-phase asynchronous motor is connected to the second single-phase asynchronous motor; Among them, a visual shooting operation is performed in front of a dual-motor working scene to obtain and output a corresponding instant visual picture. The dual-motor working scene contains a first single-phase asynchronous motor and a second single-phase asynchronous motor, which are used to collaboratively generate the same output power, including: the real-time resolution of the instant visual picture is monotonically positively correlated with the output power.

[0006] Therefore, the present invention has at least the following beneficial technical effects: Technical effect 1: Identify the image block occupied by the first single-phase asynchronous motor in the received tilt-corrected image as a reference image block, obtain the geometric shape of the edge of the reference image block, and when the obtained geometric shape is missing relative to the geometric shape of the reference shape pattern corresponding to the first single-phase asynchronous motor, obtain the depth of field value of the first single-phase asynchronous motor in the tilt-corrected image and the depth of field value of the second single-phase asynchronous motor in the tilt-corrected image; Technical effect 2: When the difference between the depth of field value of the first single-phase asynchronous motor in the tilt correction image and the depth of field value of the second single-phase asynchronous motor in the tilt correction image is less than or equal to the set depth of field limit, it is determined that the first single-phase asynchronous motor is connected to the second single-phase asynchronous motor; otherwise, it is determined that the first single-phase asynchronous motor is not connected to the second single-phase asynchronous motor, thereby achieving effective resolution of the contact state between the first single-phase asynchronous motor and the second single-phase asynchronous motor; Technical effect three: The voice playback mechanism is used to perform voice playback of vibration warning information corresponding to the connection between the first single-phase asynchronous motor and the second single-phase asynchronous motor when the first single-phase asynchronous motor of the customized visual analysis is connected, thereby completing high-precision detection and warning of whether the motors working in coordination with the dual motors are in contact.

[0007] The anti-vibration dual single-phase asynchronous motor scene analysis system of the present invention is stable in operation and easy to operate. Since it can intelligently judge whether the first single-phase asynchronous motor and the second single-phase asynchronous motor are connected based on the targeted screened visual basic data, and execute the vibration warning corresponding to the connection between the first single-phase asynchronous motor and the second single-phase asynchronous motor when they are connected, it can complete the high-precision detection and warning of whether the motors working in coordination with the dual motors are in contact.
