The MCU module of the point code identification device is connected with the USB interface module and the network interface module through the data lines to extend various external interfaces, and reading pronunciation, reading videos and other information input and output functions are realized.
Description
Technical field
The present invention relates to a kind of label coding identification equipment, relate in particular to a kind of code identification equipment.
Background technology
Traditional printing article service efficiency is low, and the user can only come expression content through reading literal and picture form, can't come literal and pictorial information in time to embody through audio-frequency information and video information anywhere or anytime.Along with popularizing of computer and network; Printed matter begins to develop to the multimedia digital direction, and the use of multimedia printed matter is following: on the textbook printed matter, print additional the shallow sign indicating number of two dimension, select to want certain one page of reading; Utilize some code identification equipment at will to click the pattern on this page; Literal, numeral etc., some code identification equipment just can be discerned the shallow sign indicating number of two dimension just can send corresponding pronunciation.
Existing in the market various somes code identification equipment can be realized reading pronunciation or reading video, but can't accomplish to have dual mode simultaneously.In addition, existing identification equipment relatively seals, and lacks the associated interface with resource external, and the waste external resource can't accomplish and compatibilities such as existing terminal such as personal computer, notebook, PAD that the waste hardware resource can't be connected to network.Therefore, be necessary existing code identification equipment is improved, the expanding peripherals interface can be realized reading pronunciation, reading video and other information input/output functions simultaneously.
Summary of the invention
Technical matters to be solved by this invention provides a kind of code identification equipment, has multiple Peripheral Interface, can realize reading pronunciation, reading video and other information input/output functions simultaneously.
The present invention solves the problems of the technologies described above the technical scheme that adopts to provide a kind of code identification equipment; Comprise the MCU module; The power end of said MCU module links to each other with power module; Input end links to each other with photoelectric sensor through the A/D sampling module, and output terminal harmony sound control control module links to each other, and links to each other with usb interface module, Network Interface Module through data line.
Above-mentioned some code identification equipment, wherein, said power module is the 3.7V lithium battery.
Above-mentioned some code identification equipment, wherein, said sound control module comprises pronounciation processing chip, power amplification unit and microphone.
Above-mentioned some code identification equipment, wherein, said photoelectric sensor is a cmos sensor.
Above-mentioned some code identification equipment, wherein, said Network Interface Module is Ethernet interface unit or wireless communication interface unit.
The present invention contrasts prior art has following beneficial effect: provided by the invention code identification equipment; The MCU module is linked to each other with usb interface module, Network Interface Module through data line; Expand multiple Peripheral Interface, thereby realize reading pronunciation, reading video and other information input/output functions simultaneously.

Photoelectric sensor 4 major functions are to accomplish IMAQ; Can select CMOS (Complementary Metal-Oxide-Semiconductor for use; Complementary metal oxide semiconductor (CMOS)) sensor; Like Agilent (HP), the product of manufacturers such as ST (VLSI Vision), Omni Vision, modern times, Photobit.Can add the duty that two light emitting diodes are used to indicate cmos sensor in addition.
A/D sampling module 2 major functions are to make signal condition, and the electric signal shaping is amplified, and can select various AD conversion chips commonly used for use, in order to guarantee acquisition precision, can add operational amplifier before the AD conversion chip.Sound control module 5 mainly comprises speech chip, miniwatt power amplifier and microphone, is used for displaying audio file and recording.Power module 3 can be selected the 3.7V lithium battery for use, and configurable in addition LED light is supplied power, charging and electric weight show.Network Interface Module 7 is Ethernet interface unit or wireless communication interface unit, launches no longer one by one to detail at this.
Fig. 2 puts the reading pronunciation process flow diagram of code identification equipment for the present invention.
Please continue referring to Fig. 2, the present invention puts code identification equipment when not connecting external unit, only possesses the reading function of pronunciation, and concrete reading pronunciation flow process is following:
Step S201: photoelectric sensor 4 images acquired;
2 pairs of Information Monitorings of step S202:A/D sampling module are adjusted;
1 pair of adjusted information of step S203:MCU module is decoded and is found corresponding audio files, calls sound control module 5;
Step S204: sound control module 5 displaying audio files, thus realize the reading pronunciation.
Fig. 3 puts code identification equipment and external device communication process flow diagram for the present invention.
Please continue referring to Fig. 3, can the input of realization information import out function after the present invention puts code identification equipment and external unit is connected, communication process is following:
