Description
Technical field
The utility model relates to printing technique, is a kind of print system of utilizing simulated audio signal transmission data that is applicable to mobile device specifically.
Background technology
Smart mobile phone and panel computer have become in people's life has used the important tool of taking pictures with shorthand, and the word of these photos or record is changed into the written material of more easily watching or reading, just must be by means of printer.But only have in the market the portable printer of minority to be directly connected with mobile phone or panel computer by USB, carry out print out task, or the hot swap type storage card insertion printer of mobile device is printed.But have following point: 1, the standard usb interface of the mobile device of different brands is inconsistent, cause printer can not take into account all mobile devices, versatility is poor; 2, in storage card, often have compared with multifile, search printing target and will spend the more time; 3, storage card small volume, repeated disassembled and assembled is easily damaged, and easily loses; 4, current mobile device more and more trends towards large fuselage capacity in addition, and storage card is used and also will reduce.
Utility model content
Task of the present utility model is will be for above-mentioned technical matters, propose a kind of versatility good, can be by mobile phone and the direct-connected print system of utilizing simulated audio signal transmission data of printer.
Technological means: the utility model discloses a kind of print system of utilizing simulated audio signal transmission data, comprise intelligent mobile terminal equipment and printer, wherein: intelligent mobile terminal equipment comprises microcontroller and simulated audio signal output port; Printer comprises simulated audio signal input port and operating circuit that can process analog audio signals; The simulated audio signal output port of intelligent mobile terminal equipment and the simulated audio signal input port of printer are connected.
The operating circuit of printer comprises prints control circuit module, mould/number conversion circuit module and decoding circuit module, simulated audio signal is transfused to described analog audio data input port, through mould/number conversion circuit module, be converted to digital signal, and after the decoding of decoding circuit module, control circuit module is printed in input.
Mould/number conversion circuit module is pcm encoder circuit.
Decoding circuit module is manchester decoder circuit.
Simulated audio signal output port and simulated audio signal input port are respectively 3.5mm standard earphone jack and plug.
Intelligent mobile terminal equipment is smart mobile phone, panel computer.
Beneficial effect: 1, directly mobile terminal device is connected and can be printed work by 3.5mm audio frequency data interface with printer, without other equipment, easy to use; 2, versatility is good, and all audio frequency apparatuses all have audio output function, and the generally application on mobile device of the audio interface of 3.5mm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of print system of utilizing simulated audio signal transmission data, comprise intelligent mobile terminal equipment 1 and printer 2, intelligent mobile terminal equipment 1 is smart mobile phone or panel computer, it is provided with microcontroller 11 and simulated audio signal output port 12, and microcontroller 11 is provided with printer application; Printer 2 is provided with simulated audio signal input port 21 and operating circuit that can process analog audio signals, the operating circuit of this printer comprises prints control circuit module 22, mould/number conversion circuit module 23 and decoding circuit module 24, mould/number conversion circuit module 23 is pcm encoder circuit, and decoding circuit module 24 is manchester decoder circuit.Simulated audio signal output port 12 and simulated audio signal input port 21 are respectively 3.5mm standard earphone jack 12 and plug 21.
During use, intelligent mobile terminal equipment 1 is connected with plug 21 by 3.5mm standard earphone jack 12 with printer 2, Intelligent mobile equipment 1 is selected text or the picture that will print, by microcontroller 11, call printer application text or picture are printed to instruction encapsulation, Manchester's cde, then the mode with analog recording is converted into audio format file by the file after coding, by earphone jack 12, is transferred to printer 2.What printer 2 received is simulated audio signal, and simulated audio signal passes through pcm encoder circuit code, then by having obtained encapsulating text or the picture of print command after the decoding of manchester decoder circuit, resolves print command, and complete print job.
