Abstract

The invention discloses a stepping motor working state monitoring method and device and an air-conditioning controller. The method comprises the steps of performing signal transformation for a driving signal of a stepping motor to obtain a corresponding signal level; performing signal processing for the signal level to obtain a corresponding square signal; and performing cycle monitor for the driving signal of the stepping motor based on the square signal to determine the operating state of the stepping motor. According to the scheme of the invention, the problems including low reliability, bad accuracy and big maintenance difficulty and the like in the prior art are solved, and the beneficial effects including high reliable, good accuracy and small maintenance difficulty are realized.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for monitoring the working state of a stepping motor and an air conditioner controller. Background technique [0002] In the development of existing air conditioners, there are abnormal waveforms in the drive level signal of the stepper motor during actual operation. However, the existing monitoring and display instrument for the working state of the stepping motor cannot handle this abnormal signal, and cannot guarantee the accuracy of the monitoring data. [0003] For example: if Figure 7 As shown, the waveform in the middle of the three waveforms, the marked position is the abnormal waveform of the driving stepper motor signal during the operation of the stepper motor. This waveform is intractable to existing techniques due to both the depth and duration of the dip. [0004] In the prior art, there are defects such as low reliability, poor preci...
