Abstract
The utility model relates to an optical character recongnition scanning pen connecting a smart phone through Bluetooth. The scanning pen sends optical character images to a smart phone through Bluetooth wireless technology, optical character recognition is carried out by a mobile phone application software set on the smart phone, and recognition results are displayed on the liquid crystal display of the mobile phone.
Description
Affiliated technical field
The technical field that the utility model relates to comprises blue tooth wireless technology connection, smart mobile phone application and development and optical character identification.
Background technology
Existing on the market at present wand mainly contains two kinds.But a kind of is the wand that off line is independently used, and a kind of in addition is the wand that connects computer through the usb data line.
● the shortcoming that off line is independently used is that the central processing unit of requirement wand is very powerful, otherwise speed is very slow, and cost is very high.An off-line scan sweep velocity of on market, selling at present is slower, and costs an arm and a leg.
● the shortcoming that connects computer through the usb data line is to use inconvenience.USB has the existence of data line first; Second must connect computer, even but connect notebook computer, also very inconvenience.
So already present these two kinds of wands are difficult in large tracts of land popularization on the market owing to above two kinds of reasons cause it.
Summary of the invention
In order to overcome two shortcomings of the existing wand of mentioning in the above background technology, the utility model design provides a kind of user of letting the convenient low-cost wand that uses.At first, the smart mobile phone that utilizes the user to buy reduces the cost of wand; Secondly, connect replacement USB connection of intelligent mobile phone, use more convenient with blue teeth wireless.
The utility model solves the technical scheme that its technical matters adopted:
At the inner bluetooth module that adds of wand; The character scan image data that wand obtained is sent to bluetooth module by wand central interior processor (CPU) through serial ports; Be sent to mobile phone by bluetooth module through wireless mode again, utilize the processor of mobile phone to carry out optical identification.
The beneficial effect of the utility model:
● cost reduces
The hardware cost that utilizes the handset processes device to handle can to reduce wand (only transmits data but not optical character identification does not need central processing unit (CPU) that very high processing power is arranged.Utilize mobile phone liquid crystal display display result, can let wand save the cost of liquid crystal display.
● easy to use
Because wand no longer needs powerful processors, can dwindle physical dimension, reduce the power consumption of lithium electricity.Wand no longer needs liquid crystal display, can dwindle physical dimension equally, reduces the power consumption of lithium electricity.
● software function is more powerful
Depend on the powerful hardware resource of operation system of smart phone and mobile phone, can let the more powerful and hommization of software function.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the modular structure schematic diagram of the utility model.
Obtain character picture information as inductor through the camera lens that is added in its front among the figure, be sent to central processing unit through bus, central processing unit is forwarded to bluetooth module through serial ports, is sent to smart mobile phone by bluetooth module through wireless mode then.
Operation system of smart phone receives character picture information through bluetooth, gives the upper strata relevant character recognition application software, after identification, on the liquid crystal display of smart mobile phone, shows recognition result.
Embodiment
Embodiment is following:
The inner image inductor of wand obtains character picture information through the camera lens that is added in its front, is sent to central processing unit through bus, and central processing unit is forwarded to bluetooth module through serial ports, is sent to smart mobile phone by bluetooth module through wireless mode then.Bluetooth speed can be adjusted according to the performance of mobile phone.
Operation system of smart phone receives character picture information through bluetooth, gives the upper strata relevant character recognition application software, after identification, on the liquid crystal display of smart mobile phone, shows recognition result.
Claims (2)
1. the optical character identification wand through bluetooth connection of intelligent mobile phone is characterized in that: said optical character identification wand set inside bluetooth module and central processing unit, this bluetooth module wireless connections smart mobile phone.
2. the optical character identification wand through bluetooth connection of intelligent mobile phone according to claim 1 is characterized in that: said optical character identification wand is given smart mobile phone the optical character image transfer that image inductor obtains through the blue teeth wireless mode.
