The embodiment of the invention provides an encoder fault processing method and device, equipment and a storage medium. The method comprises the following steps: entering an encoder detection process when an encoder fault signal is obtained; when the preset condition for safe operation of the elevator is met, the encoder detection process continues; when the preset condition of safe operation of the elevator is not met, the encoder detection process is quitted; detecting whether the star sealing function is normal or not, and continuing the encoder detection process when the star sealing function is normal; when the star sealing function is abnormal, the encoder detection process is quitted; opening a band-type brake, and detecting a first frequency and a second frequency, the first frequency being the current frequency of the three-phase current of the permanent magnet synchronous motor, and the second frequency being the frequency of the encoder pulse signal; and determining whether a reset fault occurs according to the first frequency and the second frequency. According to the scheme, whether the reset fault exists or not is determined through processing, the fault can be checked and processed in time, and safe operation of the elevator is guaranteed.
