This invention discloses a hydrocyclone pressure adaptive control method based on a soft-sensor model of slurry flow rate and concentration, comprising the following steps: A. Establishing the soft-sensor model and constructing a training dataset: A pressure transmitter, frequency converter, and current sensor are installed on the outlet pipe of the hydrocyclone feed pump; a current sensor is installed on the motor of the feed pump; and a pressure transmitter is installed on the hydrocyclone feed pipeline. Historical datasets are synchronously collected and correlated within an initial period, and manual timed sampling is also performed.

This application relates to a beveling method, apparatus, processing equipment, and readable storage medium. The method includes: a follow-up control mechanism moves a processing head along a processing trajectory at a desired processing position on a thick plate; collecting surface position data of the thick plate; and determining relative position change data based on the surface position data. The follow-up control adjusts the positions of the processing head in the X and Y directions to maintain target distances in the X and Y directions between the processing head and the processing surface of the thick plate. Based on the relative position change data, interpolation follow-up control adjusts the position of the processing head in the Z direction to ensure that the processing head processes the thick plate along the processing trajectory. This method, based on the follow-up control of the processing head's X and Y direction positions and its initial Z direction position, uses interpolation follow-up control to ensure that the control trend of the processing head in the Z direction is consistent with the surface undulation trend of the thick plate, ensuring that the processing trajectory accurately matches the preset processing requirements.
