In the use process of the Intelligent gesture interactive system, the patient or deaf-mute that inconvenience is spoken are needed first with reference to behaviour
It explains and wears myoelectricity induction bracelet 200, then myoelectricity is connected by bluetooth module and incudes bracelet 200 and control device 100, user
Corresponding gesture is made according to content to be expressed, myoelectricity induction bracelet 200 is made to collect corresponding hand signal and send
It is handled to control device 100.
Corresponding sentence is converted and exported to 100 arch-rival's gesture signal of control device, through sound-compound-circuit 130 and
Loudspeaker 150 broadcast and by 160 display statement text information of display screen.Therefore by the Intelligent gesture interactive system, no
Just the gesture that the patient or deaf-mute to speak makes can accurately be converted to the sound or text that other people can understand, facilitate other people with
The patient or deaf-mute that inconvenience is spoken link up.
In order to preferably look after the inconvenient patient or deaf-mute to speak, the Intelligent gesture interactive system can also be to inconvenience
The gesture of the patient or deaf-mute that speak are analyzed.For example, when the patient or deaf-mute that inconvenience is spoken encounter emergency case,
Its gesture instruction that can be made alarm to control device 100 or ask for help, after carrying out intelligent recognition by main control chip, by
WiFi module exports alarm signal to the Intelligent gesture interaction APP on the relatives of user or the mobile phone of friend, reminds the parent of user
People or friend know.After the relatives or friend of user know alarm, it can also pass through the App return information on mobile phone to display screen
160, informing user, it is being come.
In addition, the control device 100 further includes speech recognition circuit 170 and microphone 180, the speech recognition circuit
170 are separately connected microphone and governor circuit 110.The sentence that normal person says is received by microphone 180, and by speech recognition
Circuit 170 identifies and carries out output on display screen 160 and shows, to realize the function that patient interacts face-to-face with normal person.
In the specific embodiment being configured to control device 100, the selection of governor circuit 110 can be used following
Scheme:
Scheme one: using single-chip microcontroller that is classical, being suitble to introduction Arduino/Genuino Uno.
Scheme two: enhanced 2560 single-chip microcontroller of Arduino Mega is used.
The microcontroller development board of ATmega328P only has 14 digital input/output pins and 6 analog input pins, and its
Hardware serial ports is few, the space flash is small；And the development board of enhanced 2560 single-chip microcontroller of Arduino Mega have 54 numeral inputs/
Output pin (wherein 15 tunnels may be used as PWM output), 16 tunnel simulation inputs, 4 UART(hardware serial ports) and the space flash
Greatly, IO is more, hard string is more, is suitable for doing Internet of Things project.Therefore, governor circuit 110 is preferred in the utility model selects model
For the singlechip chip of Arduino Mega 2560.
Following scheme can be used to the setting of sound-compound-circuit 130:
Scheme one: OSYNO6188 chipspeech is used.
Scheme two: SYN6288 chipspeech is used.
The small in size, cheap of OSYNO6188 chipspeech, support GB2312 coded format etc., but the core
Piece is relatively low in intelligent recognition degree and operating aspect；SYN6288 chipspeech is the very strong TTS core of a integrated application
Piece, sound it is limpid it is mellow and full, word speed is moderate, naturalness is high, intelligibility is high, anti-noise ability is strong (under noisy noisy environment more
It is easy to understand), and built-in power amplifier, the loudspeaker 150 of 8 Europe 0.5W can be directly driven, and increase multiple volume adjustments and text
Control label etc..Therefore, SYN6288 chipspeech is preferably directlyed adopt when being configured to sound-compound-circuit 130.
Following scheme can be used to the setting of WiFi module in radio communication circuit 140:
Scheme one: CC3200WiFi module is used.
Scheme two: ESP8266WiFi module is used.
The hardware low-power consumption radio frequency of CC3200WiFi module supports TLS/SSL connection and highly integrated ICP/IP protocol stack
Be served by, but it is at high cost complicated for operation；ESP8266WiFi module it is cheap, easy to operate, and provide API, relatively
It is easy exploitation.It therefore, is preferably ESP8266WiFi module for WiFi module.
For speech recognition circuit 170, the present embodiment uses the voice recognition chip of the YS-LDV7 of LD3320, in sound
Source can accurately identify voice in suitable situation.It is worth noting that, the specific structure of above each chip or module or
Connection type can directly adopt existing way and be configured, therefore the utility model does not repeat them here this.
Meanwhile for the shell of control device, it is preferred to use acrylic board design.Acrylic shell has the advantage that
1, material is cheap；2, anti-impact force is strong；3, excellent insulating property；4, easy to maintain, it is easy to clean.
In addition, bracelet 200 is incuded for the myoelectricity for acquiring hand signal, using based on surface muscle telecommunications
Number identification technology.The myoelectricity induction bracelet 200 is selected as the embedded bracelet of gForce, is sensed by eight channel medical grade myoelectricities
Device is close to the skin surface of user, the electric signal generated when around acquisition muscle movement, and the static state to identify finger and wrist is dynamic
Make.Determine that arm space mobile data, the two combine the spatial movement and gesture to arm by nine axis movement sensors simultaneously
It is identified.Last gForce bracelet sends hand signal, and control device 100 customizes Bluetooth adapter using gForcejoint
Receive the hand signal that gForce bracelet sends over.
More specific gesture acquisition principle are as follows:
Electromyography signal (EMG) is moving cell action potential (MUAP) over time and space folded in numerous muscle fibres
Add.Surface electromyogram signal (SEMG) is that electrical activity, can be one in the comprehensive effect of skin surface on superficial muscular EMG and nerve cord
Determine to reflect nervimuscular activity in degree.
Generation -90mV is arrived the potential difference of 30mV by current potential when muscle movement, since human body is non-conductor (the 1M Ω number of electricity
Magnitude internal resistance), therefore the peak value of 1mV or so can only be obtained from the patch electrode of body surface.Since this electric potential signal is very small,
So needing to send singlechip control panel processing to again after amplifier amplifies, will be used in myoelectricity induction bracelet 200
Signal is exaggerated 800 times by amplifier.Control device 100 passes through the difference pair for judging the different collected each signal values of gesture
Gesture distinguishes.Recognizer uses BP algorithm approximating function: g (x)=1+sin (k*pi/4*x).
After gesture successful acquisition, only speech synthesis need to be added to fill by program the gesture correctly identified the meaning to be expressed
It sets and broadcasts.
The data acquisition principle of myoelectricity induction bracelet 200 are as follows:
That installs on the core board of gForce bracelet has MPU9250 chip, after gForce bracelet is worn on arm,
MPU9250 is connect by internal IIC with peripheral control unit, has nine built-in axis gyroscopes to detect current posture original number
According to collected original acceleration and angular velocity data being transmitted to peripheral control unit, by the algorithm logarithm in peripheral control unit
Current practical posture is obtained later according to processing.Control steering engine on the development board of governor circuit is transmitted data to by bluetooth to allow
Angle as rolling over.
