Abstract
The utility model relates to the field of electric fans and provides a voice-controlled electric fan which aims at solving the problems that a method of manually controlling an existing electric fan is inconvenient to people of the blind, physical disability or movement inconvenience and the like. The voice-controlled electric fan comprises an electric fan provided with a voice recognition control unit, the voice recognition control unit comprises a frond end processing unit for acquiring a voice signal, a voice recognition unit and a control unit which are sequentially connected, wherein the voice recognition unit is used for recognizing the voice signal and sending out a control signal, and the control unit is used for controlling states of wind speed, timing and the like of the electric fan. The voice-controlled electric fan controls the working states of wind, working timing, 'head shaking' and the like of the electric fan and solves the problems of inconvenience that the blind, physical disability or movement inconvenience manually set the working states of the electric fan.
Description
Technical field
The utility model relates to a kind of electric fan, and a kind of a kind of voice control electric fan that can its working state of term sound control system is provided.
Background technique
Present electric fan is by the button that manual setting is installed on the electric fan working state of electric fan to be set mostly, but concerning with blind person, physical disabilities or handicapped crowd, the working state that electric fan manually is set is very inconvenient.
Summary of the invention
The utility model provides a kind of a kind of voice control electric fan that can control by voice the working state of electric fan for the deficiencies in the prior art.
The utility model is by the following technical solutions for achieving the above object:
A kind of voice control electric fan is characterized in that comprise electric fan, described electric fan disposes the speech recognition controlled unit, and described speech recognition controlled unit comprises front-end processing unit, voice recognition unit and the control unit that is linked in sequence; Described front-end processing unit comprises MIC microphone, operational amplifier, frequency overlapped-resistable filter and the analog-digital converter that is linked in sequence; The Flash of the ephemeral data when described voice recognition unit comprises dsp processor, stores the SDRAM of initialize routine and voice comparing module, is used for the storage system operation, be used for arranging and the push-button unit of training utterance comparing module; Described control unit comprises single-chip microcomputer and the alignment circuit that is connected with single-chip microcomputer, shake the head rotating vane circuit, time circuit.
Further, the analog-digital converter of described front-end processing unit is connected with the dsp processor of voice recognition unit, and the dsp processor of described voice recognition unit is connected with the single-chip microcomputer of control unit.
Further, described dsp processor adopts the TMS320VC5402 model.
Further, described analog-digital converter adopts the TLC320AD50C model.
Further, described single-chip microcomputer adopts AT89C51.
The utlity model has following beneficial effect:
The utility model is by the wind-force size of speech recognition controlled electric fan, and the operating time, regularly working staties such as " shaking the head " solved blind person, physical disabilities crowd or handicapped crowd by the inconvenience of electric fan working state manually is set.
Description of drawings
Fig. 1 is the utility model system block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The utility model comprises electric fan, and described electric fan disposes the speech recognition controlled unit, as shown in Figure 1, is divided into front-end processing unit, voice recognition unit, control unit on the speech recognition controlled whole unit.
Front-end processing unit comprises MIC microphone, frequency overlapped-resistable filter, operational amplifier and the analog-digital converter that is linked in sequence.MIC microphone is used for gathering the speech command signal, the speech command signal that collects at first amplifies through operational amplifier, then by giving analog-digital converter behind the frequency overlapped-resistable filter elimination high-frequency interferencing signal, analog-digital converter is converted into digital signal with the analog voice command signal that collects, so that follow-up voice recognition unit uses.
Voice recognition unit comprises dsp processor, store the SDRAM of initialize routine and voice comparing module, the Flash of the ephemeral data when being used for the storage system operation, the push-button unit that is used for setting and training utterance comparing module, after the digital speech command signal that dsp processor receiving front-end processing unit is sent here, voice digital signal is processed, the initialize routine that namely arranges in advance by operation in the Flash storage is identified with the voice comparing module that realizes storage or training and is compared, and then transmits control signal to follow-up control unit according to the recognition result that obtains.
Described control unit comprises single-chip microcomputer and the alignment circuit that is connected with single-chip microcomputer, shake the head rotating vane circuit, time circuit.Described single-chip microcomputer receives the recognition result of speech recognition controlled unit, after recognition result is judged the working state of alignment circuit, shake the head rotating vane circuit, time circuit is controlled.
