Abstract
The invention relates a card early education machine system and belongs to the field of early education machines. The card early education machine system adopts a method of coding infrared recognition letters or other contents, the coding particularly comprises the followings: emitting fixed-frequency infrared light, emitting preset wave-length infrared light, adding a light filter, and arranging a first place in a card position recognizing region to be a white bar, error recognition can be fully avoided through the combined use of the four ways, content information such as word information or sentences and the like is formed through location recognition and shifting registers, and after decoding by a processor, reading is performed. The method overcomes defects in an original early education machine, the recognition way is more accurate and safe, when letters form a correct word, the word can be read after automatic recognition, one-to-one corresponding card information reading no longer exists, or when preset content combination is correct, the words or stories can be recognized automatically, and reading is performed.
Description
Technical field
The present invention relates to card early learning machine system, it belongs to early learning machine field.
Background technology
In the early learning machine of current use, normal use LED card detection technique identification card, because the antijamming capability of LED card detection technique to environmental factor (such as humidity, light and PCB surface ion) is more weak, cause identifying or None-identified card by mistake, new technology is had to adopt Quick Response Code detection technique, but be one_to_one corresponding identification, the corresponding one group of information of fixing of Quick Response Code, inconvenient children for learning, also children's interest cannot be caused, common early learning machine is all one_to_one corresponding information, and a card only comprises the information of this card.And the early learning machine of band spelling function of reading aloud is when when underage child is illiterate, cannot use.
Summary of the invention
In view of the defect that prior art method exists, the invention provides card early learning machine system, the method is by infrared identification letter or the other guide of encoding, encode particular by transmitting fixed frequency infrared light, launch predetermined wavelength infrared light, by increasing optical filter, by arranging first, card position cog region for informal voucher, these four kinds of modes combinationally use fully to be avoided identifying by mistake, the content information such as word information or sentence is combined into by location recognition and shift register, after processor decodes, and read aloud.The method overcomes the defect of original early learning machine, recognition method is safety more accurately, and reading aloud word after can automatically identifying when letter forms correct word, is no longer that card image is read aloud one to one, or automatic identified word or story, read aloud when preset content combination is correct.
For achieving the above object, the technical solution adopted in the present invention is card early learning machine system, comprises several cards, identification module, processor, speech chip, power amplifier chips, loudspeaker; Identification module is connected with processor, and processor is connected with speech chip, and speech chip is connected with power amplifier chips, and power amplifier chips is connected with loudspeaker; Storer is had in described speech chip; Card comprises cog region and literal field.
Described identification module comprises infrared mutual-tube array and some shift registers; Described infrared mutual-tube array is made up of some groups of infrared mutual-tube groups; Described each infrared mutual-tube group is made up of infrared mutual-tube some.
Often open described card corresponding with an infrared mutual-tube group; Described infrared mutual-tube to be connected with single-chip microcomputer by shift register and to drive.
Described infrared mutual-tube comprises infraluminescence pipe and infrared remote receiver; Described infraluminescence pipe leading portion covers the infrared fileter of 950nm;
Described infraluminescence pipe is selected to launch 950nm infrared light.
Several shift register serial cascade described use; Described shift register is 74HC165.
Described cog region comprises content recognition district and location recognition district.
Described cog region becomes band by several secret note alternately with informal voucher.
First of the identification of described location recognition district is white ribbon.
Described processor is single-chip microcomputer, and described single-chip microcomputer is STM32F103.
Described card early learning machine also comprises bluetooth module.
The corresponding infrared tube group of each described draw-in groove, an infrared tube group represents an identified region scope, a namely position on card early learning machine, if do not arrange draw-in groove, know the corresponding different infrared tube group in black and white bar district in Do district by arranging different card position, different infrared of the reflection received with infrared receiving tube is identified in positions different on early learning machine.
Card camera identifying is: described infrared transmitting tube launches infrared light, the infrared light sent is passed string by shift register turn and be input to processor and control the break-make of infraluminescence tube current signal, infrared light reflects after running into card recognition district, the infrared signal of reflection is received by infrared receiving tube, light signal is converted into electric signal, electric signal is imported into and turns the cascade of string device shift register and use, then Serial output is to processor, processor carries out decoding and judges, the card card content information judged transfers the corresponding contents in storer by voice core, the content of card combination is read again by voice power amplifier chips and loudspeaker.
Identify and adopt infrared light reflection, black matt face can absorb infrared energy to greatest extent, infrared energy on such correspondence position would not reflex to receiving tube, receiver can not receive signal, and white even curface (surfaces of common printed product) can greatly reflected infrared, the infrared receiver tube of so corresponding position can have infrared receiver signal, can by Circuits System identification.
The information of card just can be judged according to the monochrome informatio on card, in order to strengthen antijamming capability, the infrared light sent is encoded, decode finally by processor, the interference of natural light and maloperation can be got rid of like this, the mode one of coding is by launching the infrared light of fixed frequency 950nm, but by the glow frequency of infrared light.
Infraluminescence selects 950nm to pipe, and the energy of 950nm inside natural light has not been very strong, and we cover the infrared fileter of 950nm in front end, in order to filter the interference that natural light and illuminating ray bring.
Ultrared frequency can be sent by Single-chip Controlling, thus reach infrared light coding, prevent from identifying by mistake.
First, location recognition district is set to white ribbon, can prevent from identifying by mistake.
Microprocessor is controlled by IO, be connected with signals such as DATA, CS, CLK, ENABLE of 74HC165, cascade is carried out in the input and output of 74HC165, and the embedded program of single-chip microcomputer is identified a series of infrared tube identification signal by these ports.
After adopting said method, there is following beneficial effect compared with art methods: the accurately Letter identification mode of safety, children arbitrarily can combine letter, word is read aloud time correct, cause children for learning interest, be applicable to the children that low age is illiterate, this card early learning machine accurate stable is high simultaneously, can not misread simultaneously, not by environmental interference, stability is high, can also be furnished with story card, word flash card, allow children's combination in any, transfer sentence or phrase allusion is read aloud, cause children's interest, and early education.
