Abstract
A kind of optical character identification wand being connected smart mobile phone by ultrasonic communication, wand is sent to smart mobile phone the character gone out by optical character image recognition through loudspeaker by ultrasonic communication, by smart mobile phone by after microphones, mobile phone liquid crystal screen shows result.
Description
Art
The technical field that the utility model relates to comprises ultrasonic communication, smart mobile phone application and development and optical character identification.
Background technology
Wireless connections wand existing on the market at present, mainly contains two kinds.Be a wand for the direct connecting Internet of WIFI, another is the wand being connected smart mobile phone by bluetooth.
● the shortcoming of the wand of the direct connecting Internet of WIFI is that requirement wand hardware possesses WIFI module, and can only use providing the place of WIFI signal.The wand price of the direct connecting Internet of WIFI commercially sold at present is very expensive.
● the shortcoming of wand connecting smart mobile phone by bluetooth requirement wand hardware possesses bluetooth module and bluetooth module is expensive and possess larger volume, makes the wand developing super-small become abnormal difficult.Commercially sell at present connect that the wand price of smart mobile phone is very expensive by bluetooth and size is very large.
So these two kinds of wireless connections wands already present cause it to be difficult to commercially spread due to above-mentioned reason.
Summary of the invention
In order to overcome two shortcomings of the existing wireless connections wand mentioned in above background technology, the utility model design provides a kind of low cost wand making user easy to use.First, the low cost miniature loudspeaker that wand configures is utilized to send ultrasound wave to reduce the radio communication cost of wand; Secondly, utilize the microphones ultrasound wave that smart mobile phone carries, without the need to adding any hardware components, cost-effective make to use simultaneously more convenient.
The utility model solves the technical scheme that its technical matters adopts:
Low cost miniature loudspeaker is added in wand inside, the character that wand obtains carries out coded modulation by central processing unit (CPU) in the frequency of insensitive 19000HZ to the 20000HZ of people's ear, and formation analog electrical signal is transferred to loudspeaker after being transformed by digital-to-analogue, amplify this signal by loudspeaker again to form ultrasound wave and be sent to mobile phone through air, finally obtain transmitted original character by microphones after carrying out demodulating and decoding by mobile phone.
The beneficial effects of the utility model:
● cost reduces
Utilize the microphone of the low cast loudspeaker of wand and mobile phone formation ultrasonic communication can reduce the hardware cost of wand.
● use
Because wand no longer needs WIFI module or bluetooth module, can physical dimension be reduced, and reduce the power consumption of lithium electricity.The modulation /demodulation of ultrasonic communication is completely by software simulating, and the producer owing to producing Bluetooth chip when having stopped to adopt bluetooth module is different and the compatibility issue that produces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing is modular structure schematic diagram of the present utility model.
Image inductor obtains character picture information by the camera lens be added in before it, central processing unit is sent to by bus, central processing unit obtains character after character recognition, character, by transmitting analog electrical signal to loudspeaker by digital-to-analog conversion after coding and frequency domain modulation, is then sent to smart mobile phone by forming ultrasound wave after loudspeaker amplifying signal through air.
Smart mobile phone to ultrasonic signal by the microphones that carries, is given upper layer software (applications) demodulating and decoding and is obtained original character, and in the liquid crystal screen display of smart mobile phone.
Embodiment
Embodiment is as follows:
The image inductor of wand inside obtains character picture information by the camera lens be added in before it, central processing unit is sent to by bus, central processing unit obtains character after character recognition, character, by transmitting analog electrical signal to loudspeaker by digital-to-analog conversion after coding and frequency domain modulation, is then sent to smart mobile phone by forming ultrasound wave after loudspeaker amplifying signal through air.
Smart mobile phone to ultrasonic signal by the microphones that carries, is given upper layer software (applications) demodulating and decoding and is obtained original character, and in the liquid crystal screen display of smart mobile phone.
Claims (1)
1. one kind connects the optical character identification wand of smart mobile phone by ultrasonic communication, it is characterized in that: described optical character identification wand inside arranges loudspeaker and central processing unit, microphone on this loudspeaker and smart mobile phone forms unidirectional ultrasonic communication, and communication direction is from wand loudspeaker to smart mobile phone microphone.
