Abstract
The utility model discloses a device for reading and displaying paper ticket content. The device is composed of a plurality of devices, and comprises a card reader for reading information on a paper ticket. The card reader is connected with an audio port of an intelligent device and used for transmitting the information existing on the paper ticket and read by the card reader to the intelligent device. The intelligent device is provided with a processor, an analog-to-digital conversion circuit and an output device. The processor is used for converting an analog signal received by the audio port into a wave signal, the analog-to-digital conversion circuit is used for restoring the wave signal into a digital signal which can be displayed on a screen through the processor. The device for reading and displaying paper ticket content can realize electronic reading of the paper ticket content.
Description
Technical field
The utility model relates to a kind of computerized information read device, belongs to areas of information technology.
Background technology
Namely making out an invoice is a kind of implementation of common bill, be divided into that papery is namely made out an invoice and two kinds of electronic instant billings according to the difference of distribution medium, common namely making out an invoice is papery, when reading ticket contents, needing namely to make out an invoice upward, printed information is input to the content that just can learn in the special-purpose computer equipment wherein, the whole process that reads information all is specialized equipment, the use cost height, and be not easy to promote, can't take full advantage of existing high-speed computer and realize universalization and the robotization of entire equipment, can't make that also domestic consumer can be quick, read the content of namely making out an invoice easily.
Summary of the invention
In order to overcome the defective of prior art, the utility model discloses a kind of device that reads and show the content of namely making out an invoice, taken full advantage of existing computing machine and mobile phone, realized that the electronization of the information of namely making out an invoice is handled.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of device that reads and show the content of namely making out an invoice, by forming as lower member:
Card reader is used for reading the information on namely making out an invoice;
Described card reader is connected with the audio interface of smart machine, be used for card reader read namely make out an invoice on information conveyance give smart machine;
Described smart machine is provided with processor, analog to digital conversion circuit and screen, the analog signal conversion that described processor is used for audio interface is received becomes waveform signal, analog-digital conversion circuit as described is used for waveform signal is reduced to digital signal, and by processor it is shown on the screen.
Above-mentioned alleged smart machine, the universal computing device that refers to have calculation process ability able to programme can be realized different functions by it is programmed, preferred described smart machine is mobile phone, panel computer or PC.
Above-mentioned alleged namely making out an invoice namely made out an invoice for papery, is printed with bar code, magnetic stripe, RFID or circuit; Correspondingly, card reader is to adopt the device that can read the information of going up of namely making out an invoice, and for example namely makes out an invoice for bar code, and card reader is bar-code scanner or barcode scanner normally; Namely make out an invoice for magnetic stripe, card reader is the magnetic card read write line; Namely make out an invoice for RFID etc., card reader is less radio-frequency reader etc., and the equipment that reads the content of namely making out an invoice is that this area is existing, repeats no more herein.
The workflow of said apparatus is: at first, card reader reads the analog information on namely making out an invoice, analog information is flowed to smart machine by audio interface, smart machine utilizes processor according to the driving of having finished writing in advance these analog signal conversion to be become waveform signal after these information of acquisition, waveform signal is through becoming the digital signal of 0,1 form after the analog to digital conversion circuit, thereby handling to output to via processor calculating is shown as user's identifiable information on the screen, thereby knows the content on namely making out an invoice.
In said process, analog-to-digital implementation can adopt accomplished in many ways, for example adopts wave file is carried out the method that zero crossing detects to realize with analog-signal transitions being digital signal.
Further, because the content on namely making out an invoice not is all to be analog content, for digital content (for example bar code, magnetic stripe etc.), needs to convert digital signal to simulating signal earlier and just can flow to audio interface, otherwise be unrecognizable.
For addressing the above problem, corresponding, described card reader is connected with D/A converting circuit, and the numerical information on described D/A converting circuit is used for namely making out an invoice is converted to analog information and sends audio interface to.
Digital content is converted to simulating signal can adopts multiple mode to realize, for example represent 1 and 0. of digital content with the different frequency waveform
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Embodiment
With reference to figure 1, device of the present utility model comprises card reader, and described card reader is connected with D/A converting circuit; Card reader and D/A converting circuit all are connected to the audio interface (audio interface of 2.5mm, 3.5mm or private definition) of smart machine; When the content on making out an invoice at once was simulating signal, the content on card reader will namely be made out an invoice was passed to audio interface; When the content on making out an invoice at once belonged to digital content, the information that reads on the card reader was converted into simulating signal by D/A converting circuit and sends audio interface to.
After simulating signal arrives audio interface, processor obtains analog signal information and according to the definition of the driving layer of programming in advance on the smart machine simulating signal is formed waveform signal to send analog to digital conversion circuit to, and analog to digital conversion circuit converts waveform signal to according to predefined rule and after the discernible digital signal of processor is handled by processor its formation can be presented on the screen for the content that the user reads.
In above-mentioned, the applicant does not limit the mode of writing of driving etc., and to those skilled in the art, analog to digital conversion, digital-to-analog conversion, waveform signal etc. all are to have the mathematical algorithm program of plurality of optional attainable, belong to the prior art of widespread use.
Claims (4)
1. device that reads and show the content of namely making out an invoice is characterized in that by forming as lower member: card reader is used for reading the information on namely making out an invoice; Described card reader is connected with the audio interface of smart machine, be used for card reader read namely make out an invoice on information conveyance give smart machine; Described smart machine is provided with processor, analog to digital conversion circuit and screen, the analog signal conversion that described processor is used for audio interface is received becomes waveform signal, analog-digital conversion circuit as described is used for waveform signal is reduced to digital signal, and by processor it is shown on the screen.
