Abstract
The utility model discloses a sound-control temperature-regulation steering wheel sleeve, which belongs to the field of automobile electromechanical equipment. The sound-control temperature-regulation steering wheel sleeve comprises an insulated heat conducting outer layer, an electric heating layer and an insulated heat insulation inner layer and is characterized in that the sound-control temperature-regulation steering wheel sleeve also comprises a sound control regulator, wherein the sound control regulator comprises a voice pick-up device, an analog-to-digital converter and a digital signal processor chip, and the voice pick-up device, the analog-to-digital converter, the digital signal processor chip and the electric heating layer are sequentially connected. Compared with the prior art, the sound-control temperature-regulation steering wheel sleeve has the characteristics that all devices are arranged outside the insulated heat conducting outer layer of a steering wheel, the manual control of drivers is not needed, and the safe driving is favorably realized.
Description
[technical field]
The utility model relates to automobile electromechanical appliance field, particularly a kind of acoustic control temperature adjustment direction indicators cover that is used for the vehicle drive in winter.
[background technology]
The northern area winter weather cold, this causes a lot of troubles for chaufeur drives a car, and one of them causes and operates inconvenience, turns to ineffective exactly owing to the bearing circle temperature is too low.
The technology that has had at present is exactly to add last layer resistance heat material in the direction indicators cover the inside, control the temperature of bearing circle by the size of regulating resistance, but this method has the following disadvantages still:
1, the button of temperature control or knob need be installed on the bearing circle outside face, perhaps establish attemperating unit in addition by being wired on the bearing circle, are unfavorable for the safe driving of automobile.
2, present temperature control bearing circle needs chaufeur manually to control, and will certainly disperse the attention of chaufeur during driving, causes unnecessary safety misadventure.
[utility model content]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of acoustic control temperature adjustment direction indicators cover that is used for the vehicle drive in winter is provided.
The technical scheme in the invention for solving the technical problem is: a kind of acoustic control temperature adjustment direction indicators cover, comprise the insulating heat-conductive skin, electrothermal layer, the insulation and thermal insulation internal layer, it is characterized in that: also comprise the acoustic control control apparatus, described acoustic control control apparatus comprises voice pick-up, A and D converter and digital signal processor (DSP) chip, and described voice pick-up, A and D converter, digital signal processor (DSP) chip, electrothermal layer connect successively.
Above-mentioned digital signal processor (DSP) chip is hidden markov model (HMM) recognizer.
Above-mentioned acoustic control control apparatus is arranged between insulating heat-conductive skin and the insulation and thermal insulation internal layer.
Above-mentioned voice pick-up is the little silicon based condenser microphone of anti-noise.
Compared with prior art, the utlity model has following characteristics:
1, all device is arranged within the insulating heat-conductive skin of bearing circle, helps the safe driving of automobile.
2, do not need chaufeur manually to control, the attention that driving can not disperse chaufeur has been avoided unnecessary safety misadventure.
[description of drawings]
Fig. 1 is a structural principle schematic block diagram of the present utility model.
[specific embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, a kind of acoustic control temperature adjustment of the utility model direction indicators cover comprises the insulating heat-conductive skin, electrothermal layer, insulation and thermal insulation internal layer, acoustic control control apparatus.Described acoustic control control apparatus comprises the little silicon based condenser microphone of anti-noise, A and D converter and digital signal processor (DSP) chip, and the little silicon based condenser microphone of described anti-noise, A and D converter, digital signal processor (DSP) chip, electrothermal layer connect successively; Described acoustic control control apparatus, electrothermal layer are arranged between insulating heat-conductive skin and the insulation and thermal insulation internal layer.Digital signal processor (DSP) chip is hidden markov model (HMM) recognizer, and the hidden markov model recognizer is also suitable with acoustic model parameter module and parameter adaptation module.
During use, chaufeur will instruct voice training, HMM acoustic model parameter module normally the phonetic feature that obtains to be analyzed to acoustic control control apparatus of the present utility model and remembers that the back produces earlier by the little silicon based condenser microphone of anti-noise.During the winter driving automobile, chaufeur will instruct pronunciation to import acoustic control control apparatus of the present utility model by the little silicon based condenser microphone of anti-noise, the parameter adaptation module with phonetic feature and the acoustic model parameter module of input carry out adaptive with relatively, can obtain the recognition result of the best.After the identification, digital signal processor (DSP) chip is controlled the height of temperature according to the instruction of chaufeur by the size of regulating the utility model heat-conducting layer built-in resistor.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
