The invention provides a method, a system and a device for voiceprint recognition, authentication, noise reduction and voice enhancement of personnel in a power dispatching system. The method comprises the following steps: a calling user sends an operation request and a voice signal to a dispatcher through a telephone; separating a voice signal of the calling user from the mixed voice of the calling user and the dispatcher; performing noise reduction on the voice signal of the calling user; performing voice enhancement on the voice signal of the calling user; the power dispatching system matches the voice signal of the calling user with a voice signal pre-recorded by a person with the operation authority by using a trained voiceprint recognition model; and if the matching is successful, allowing the calling user to operate, and if the matching is not successful, not allowing the calling user to operate. According to the invention, the voice of the user can be accurately recognized under ...

The invention discloses a fiber Bragg grating micro-displacement sensor and a measuring method thereof. The fiber Bragg grating micro-displacement sensor is composed of a cylindrical inner shell and an outer shell, four stainless steel flexible diaphragms are disposed in four symmetrical directions between the inner shell and the outer shell, places, in contact with the outer shell, of the flexible diaphragms are fixed by welding, the outer shell is fixed on the inner shell by the aid of pressure of the four flexible diaphragms, and fiber Bragg gratings are adhered on all of the four flexible diaphragms. The fiber Bragg gratings are placed horizontally, the inner shell is fixed, relative positions of the outer shell and the inner shell change in case that the outer shell is under the action of external micro-displacement changes, the diaphragms deform to drive the Bragg gratings thereon to deform, and wavelength of the fiber Bragg gratings shifts. Since the four diaphragms are different ...

The invention provides a power dispatching system personnel voiceprint recognition authentication method, system and device. The method comprises the steps that a user sends an operation request and a voice signal to a power dispatching system; eliminating components which do not belong to the user voice in the user voice signal to obtain a pure user voice signal; constructing a voiceprint recognition model; the power dispatching system matches the received user voice signal with a voice signal pre-recorded by a person with the operation authority by using a trained voiceprint recognition model; if the matching succeeds, allowing the user to operate, and if the matching fails, not allowing the user to operate. According to the invention, the voice of the user can be accurately recognized under the condition of current and noise interference.
