Control platform for rotation speed of motor

Abstract

The invention relates to a control platform for the rotation speed of a motor. The control platform comprises an out-discharging smoke absorbing main body, somatotype recognizing equipment and power conversion equipment; the out-discharging smoke absorbing main body comprises a covering plate, a ring washer cover, a covering cap, an impeller, an air passage, the motor, a drawing pipe and a decoration pipe; the ring washer cover is arranged on the covering plate, the motor is arranged on one side of the air passage, the covering cap is arranged at the central position of the impeller and used for fixing the impeller to the motor, the drawing pipe is of a square column structure and used for packaging the motor, and the decoration pipe is connected to the lower part of the drawing pipe in asleeving mode; the somatotype recognizing equipment is used for performing somatotype matching based on wiener filtering images based on human body standard somatotype, and when the matching degree exceeds a preset percentage threshold value, power increasing instructions are issued, or power maintaining instructions are issued; and the power conversion equipment is used for increasing the rotation speed of the motor and further used for maintaining the current rotation speed of the motor to be unchanged when the power maintaining instructions are received. According to the control platform for the rotation speed of the motor, the intelligent standard of control over the motor is improved.

Description

technical field [0001] The invention relates to the field of external exhaust smoking machines, in particular to a motor speed control platform. Background technique [0002] The external exhaust smoking machine inhales the air polluted by oil fume, separates and collects the oil mist, and then discharges it to the outside through the pipe. Installed on the upper part of the stove, the impeller in the volute is driven to rotate by the electric top post in the body, forming a certain negative pressure in the air inlet area, and through the drainage of the smoke collecting chamber, a negative pressure area is formed in a certain space above the stove. , the fume gas around it is attracted by the negative pressure to reach the filter screen, and a part of large particles of oil mist are filtered out, and the rest of the gas enters the centrifugal fan system inside the hood, and the fume gas is thrown out by the centrifugal force after the high-speed rotation of the fan impeller...

Problems solved by technology

[0003] In order to solve the technical problem that the motor control intelligence level of the current external smoking machine is not high, the present invention provides a motor speed control platform, which introduces body shape recognition equipment, and is used to perform human body shape on the Wiener filter image based on the human body reference body shape. Matching, when the matching degree exceeds the preset percentage threshold, a power increase command is issued, otherwise, a power maintenance command is issued, and power conversion equipment is also introduced to connect with the motor and body shape identification equipment, which are used to increase the power when receiving the power increase command. The rotation speed of the motor is also used to maintain the current rotation speed of the motor when the power maintenance command is received; and calculate the corresponding Oscillating amplitude of the image block, so as to select the target image block for comparison
