Description

technical field [0001] The invention relates to a computer-based frequency conversion speed regulation control system. Background technique [0002] Such different motors are applied to electrical equipment in the prior art. When the motor is working, we need to monitor the working state of the motor in real time to adjust the actual working speed of the motor, so as to facilitate the control of the working efficiency of the electrical equipment. The frequency conversion speed regulation control system in the prior art has a single function, and the control chip is used to realize the regulation and control of the operation of the motor. In this way, the phenomenon of line interruption often occurs when the control is performed. Contents of the invention [0003] According to the problems existing in the prior art, the present invention discloses a computer-based variable frequency speed regulation control system, which performs wireless data communication with the upper c...
