Abstract
A kind ofly realize that mobile phone is made out an invoice, certification, printing communication connecting apparatus, relate to electronic technology field, the problem of UKEY access when it mainly solves the certification of mobile phone Net silver, it comprises the USB interface for connecting printer, carries out the MICRO USB interface of data transmission with printer; For whole device is powered, adopt low pressure difference linear voltage regulator from the power taking of MICRO USB interface, 5V electricity is converted to the power module of 3V electricity; Adopt USB interface, the UKEY interface be connected with MCU by USB interface chip; Be connected with MCU, for being connected the bluetooth module of mobile phone by bluetooth equipment; For realizing the entirety control MCU module of USB control chip, bluetooth module.The basis that the utility model does not change existing network invoice system framework realizes mobile phone terminal make out an invoice, effectively reduce taxpayer's use cost and greatly strengthen the dirigibility that taxpayer uses.
Description
Technical field
The utility model relates to electronic equipment hardware unit technical field, provide a kind ofly to make out an invoice for realizing mobile phone, certification, a kind of communication connecting apparatus in print procedure.
Background technology
Current national invoice expropriation and management system be the invoice of real-time data collection, kernal hardware Golden Taxes dish/tax control tray that invoice system client is, collection and the printing that printer realizes invoice data is added by PC, Golden Taxes dish/tax control tray, taxpayer initially has high input, and has certain requirement to place.In extension process, the acceptance of taxpayer (particularly small amount taxpayer) is poor.
Along with the development of technology, smart mobile phone performance can match in excellence or beauty with normal domestic use PC, and the portability of mobile phone, power consumption and popularity rate are PC cannot compare.Universal the proposing invoice system of smart mobile phone departs from the mobile requirement of making out an invoice of PC realization, and tax control tray in existing billing system, Golden Taxes dish directly cannot communicate with mobile phone with printer, there is the bluetooth box interconnecting device for traditional wired interface printer on the market, but still the problem communicated with tax control tray, Golden Taxes dish cannot be solved.
Summary of the invention
The purpose of this utility model is to solve mobile phone not to be had USB interface to insert UKEY to carry out Net silver authentication or network and to make out an invoice the problem printed.
The utility model is to achieve these goals by the following technical solutions:
Realize that mobile phone is made out an invoice, certification, printing a communication connecting apparatus, it is characterized in that, comprising:
MICRO USB interface: for connecting the USB interface of printer, carry out data transmission with printer;
Power module: for whole device is powered, adopts low pressure difference linear voltage regulator from the power taking of MICRO USB interface, 5V electricity is converted to 3V electricity;
UKEY interface: adopt USB interface, be connected with MCU by USB interface chip;
Bluetooth module: be connected with MCU, for connecting mobile phone by bluetooth equipment;
MCU module: for realizing the entirety control of USB control chip, bluetooth module.
In technique scheme, bluetooth module replaces with in WIFI module, infrared module, zig-bee wireless communication module, GPRS module, 3G module, 4G module, 315M/433M wireless communication module one or more.
In technique scheme, described power module is connected with working station indicator.
The application adopts a MCU as core, extends out bluetooth module and USB interface chip as communication interface, and MCU receives mobile phone software of making out an invoice and mails to the data of bluetooth module, then sends USB and issues tax control tray or printer; The data that tax control tray or printer return send to mobile phone to make out an invoice software by bluetooth module.
The utility model, because adopt technique scheme, therefore possesses following beneficial effect:
The utility model achieves the expansion by external device, mobile phone being realized to Wireless USB interface.
The invention has the beneficial effects as follows that on the basis not changing existing network invoice system framework, realize mobile phone terminal makes out an invoice, effectively reduce the dirigibility that taxpayer's use cost also strengthens taxpayer's use greatly.
Accompanying drawing explanation
Fig. 1 is circuit principle structure block diagram of the present utility model.
Fig. 2 is system architecture diagram of the present utility model.
Embodiment
As shown in Figure 1, input 5V power supply from MICRO USB5 and turn 3.3V LDO 6 through 5V and change and power to MCU 1, USB interface chip 2, bluetooth module 3,5V power supply is powered directly to USB interface 4 simultaneously.After system electrification, 3.3V power drives power light 7 is luminous.
MCU initialize internal register, USB interface chip and bluetooth module, initialization completes waits for bluetooth serial ports or usb data, when MCU receives bluetooth serial ports data, data cached and analyze packet content and determine data to mail to corresponding USB peripheral hardware.When MCU detects that usb terminal formula is interrupted producing cause by reading control chip condition adjudgement and processes by respective interrupt source: equipment inserts and interrupts, and detects the USB device type the corresponding Status Flag of set inserted; Equipment extracts terminal, checks and extracts device type and remove corresponding Status Flag; Data are interrupted, and data packing is sent to mobile phone A PP by bluetooth.MCU driving condition pilot lamp 7 flicker instruction communications status in bluetooth or usb communication process.
In the embodiment depicted in figure 2, smart mobile phone 1, Bluetooth adapter 2, collector/tax control tray 3 and printer 4, form user side billing system, mobile phone terminal is communicated with Bluetooth adapter by Bluetooth signal, Bluetooth adapter receive mobile phone terminal send data and resolution data bag content, corresponding data are sent to make out an invoice device/tax control tray or printer, in use receive any usb data, do not process and directly mail to mobile phone terminal by mobile phone A PP process by bluetooth.
