The end of thumb, the second guide passage 32 are connected to the end of forefinger, and the 3rd guide passage 33 is connected to the end of middle finger, the
Four guide passages 34 are connected to the end of the third finger, and the 5th guide passage 35 is connected to the end of little finger.
The back of the hand fixture 1 is mainly used in guide arm device being fixed on the back of the hand, and the inside of the back of the hand fixture 1 is comprising at CPU
Device and battery are managed, pole 2 is preferably elastic fulcrum bar, and for supporting whole palm, the ultrasonic sensor on guide passage 3 is used for
Measurement distance, mobile terminal 5 is used to charge to the battery in the back of the hand fixture 1 by cellular phone data line, and and CPU processor
Carry out data transmission.
As shown in Fig. 2 there is CPU processor at the back of the hand, processor is used for the ultrasound data for gathering five fingers, simultaneously
CPU processor is used for the vibrator for controlling five fingers, and data are from ultrasonic wave to CPU processor, CPU processor control vibrator
Form a set of closed-loop control system.
Embodiment two：
As shown in figure 3, a kind of multichannel ultrasonic blind-guiding method of the present invention, comprises the following steps：
Guide arm device is put on, the back of the hand fixture 1 is fixed, fixes guide passage 3 on each finger, turn on the power, open hand,
By palm, mobile awareness shakes in the presence of, puts on bluetooth earphone and obtains GPS navigation location information, mobile palm disturbance of perception thing
Locus and shape：
S1. the locus of disturbance of perception thing：The ultrasonic sensor of guide passage 3 is by the time of acoustic emission on each finger
Difference data is transferred in CPU processor, and CPU processor controls the amplitude of vibrator vibration according to the size of time difference；
S2. the shape of disturbance of perception thing：The ultrasonic sensor of guide passage 3 between each finger is by different acoustic emissions
Time difference is transferred in CPU processor, the amplitude that CPU processor vibrates according to the size control vibrator of different time difference, if
There is the Oscillation Amplitude of one or more finger upper vibration generators different from other fingers, then palm is in the boundary of barrier.
Wherein, in S1 steps, change from small to big if ultrasonic sensor exports to the time difference of CPU processor, CPU processing
The Oscillation Amplitude of device control vibrator is from large to small；If ultrasonic sensor export to CPU processor time difference from large to small,
Then the Oscillation Amplitude of CPU processor control vibrator changes from small to big；If ultrasonic sensor exports the time difference to CPU processor
Constant, then CPU processor control vibrator maintains current Oscillation Amplitude.
In step S1, launch time of the ultrasonic sensor on each finger is poor, vibrator Oscillation Amplitude is consistent.
In step S2, in the case of being worn with the right hand, thumb wears the first guide passage 31, and forefinger wears the second guide
Passage 32, middle finger wear the 3rd guide passage 33, and the third finger wears the 4th guide passage 34, and little finger wears the 5th guide passage
35：
If the guide passage Oscillation Amplitude of five fingers is identical, palm is in a plane；If the first guide passage 31,
The Oscillation Amplitude of two guide passages 32 is less than the vibration of the 3rd guide passage 33, the 4th guide passage 34, the 5th guide passage 35
Amplitude, then palm be in the left margin of barrier 6；If the 4th guide passage 34, the Oscillation Amplitude of the 5th guide passage 35 are less than
First guide passage 31, the second guide passage 32, the Oscillation Amplitude of the 3rd guide passage 33, then palm be in the right side of barrier 6
Border；If the Oscillation Amplitude of the second guide passage 32, the 3rd guide passage 33, the 4th guide passage 34 is less than the first guide passage
31st, the Oscillation Amplitude of the 5th guide passage 35, then palm be in the coboundary of barrier 6；If the second guide passage the 32, the 3rd is led
Blind vias 33, the Oscillation Amplitude of the 4th guide passage 34 are more than the first guide passage 31, the Oscillation Amplitude of the 5th guide passage 35,
Then palm is in the lower boundary of barrier 6.
Such as Fig. 3, palm maintains a certain distance with barrier 6, and palm movement drives the ultrasonic sensor of five passages,
Distance more near earthquake is dynamic stronger, and the vibrations sent by the different shock sensor of the distance of measurement can have been transmitted in difference, vibrations
To finger, the border of object can be perceived by the difference of shockproofness between finger.Such as it is moved at the A of position, five fingers
Vibration amplitude be substantially the same, this is it is thought that a plane；When being moved at B（Passage 1,2 is weak）With（Passage the last 3,4,5）
Vibrations have differences, and illustrate that palm is in the left margin of barrier 6.It is moved at C（Passage 4,5 is weak）With（Passage the last 1,2,3）
Had differences between vibrations, then this is exactly the right margin of barrier 6.It is moved at D（Passage 2,3,4 is weak）With（Passage 1,5
By force）Vibrations have differences, then this is exactly the coboundary of barrier 6.It is moved at E（Passage the last 2,3,4）With（Passage 1,5 is weak）
Vibrations have differences, then this is exactly the lower boundary of barrier 6.
The technology of the present invention can make user preferably perceive locus and the general shape of current barrier, to make
User provides a more three-dimensional sensing range, so that their safer avoiding obstacles.By the GPS location of mobile phone
Prompt message passes to bluetooth earphone, is perceived with reference to the vibrations of gloves so that user more freely moves in city.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
