Abstract

The utility model relates to a POS machine with a video advertisement playing display, which belongs to the technical field of combination of cash registers and video advertising players. The POS machine comprises a signal controlling and processing circuit with a microprocessor and a liquid crystal display module with an LCD liquid crystal display. A data displaying output port of the microprocessor of the signal controlling and processing circuit is connected with an input port of the liquid crystal display module through a video signal pushing (transmitting or converting) circuit. Therefore, various information such as cash amount, video advertisement, rolling subtitles, and the like can be displayed on the LCD liquid crystal display module through the driving or converting analysis of the video signal pushing circuit, so that the POS machine has a display function of a multimedia, and realizes more friendly use interface and more humanized products.

Description

Have video ads and play the POS machine of display

Technical field

The utility model relates to a kind of multimedia POS machine, and especially a kind of POS machine with video ads broadcast display belongs to cashier's machine and video ads machine combination technology field.

Background technology

Understand according to the applicant, the customer monitor of existing POS POS generally uses old-fashioned LED charactron to show, can only provide simple cash register amount information to show, is difficult to satisfy the needs that more information is provided to the user.

The utility model content

The purpose of this utility model is: at the shortcoming that above-mentioned prior art exists, propose a kind of POS machine with video ads broadcast display, thereby can issue more information needed.

In order to reach above purpose, the POS machine with video ads broadcast display of the present utility model comprises signal control processing circuit that contains microprocessor and the LCD MODULE that contains the LCD LCDs.The video data output port of the microprocessor in the described signal control processing circuit promotes (transmission or conversion) circuit by vision signal and connects the input port of described LCD MODULE.

Like this, promote the driving of (transmission or conversion) circuit or resolve conversion by vision signal, on the LCD LCD MODULE, can show such as various information such as the cash register amount of money, video ads, roll titless, thereby make the POS facility that more Presentation Function be arranged, the interface is more friendly, more hommization.

Embodiment

Embodiment one

Present embodiment has video ads and plays circuit main board and the LCD LCD MODULE that the POS engine housing of the POS machine of display contains signal control processing circuit.The basic comprising of this circuit main board as shown in Figure 1, with Au1200 series microprocessor chip is core, storage chip and flash chip FLASH are connected at random with cache chip DDR2 respectively for its data bus port and address bus port, its communication terminal is by the COM port of the external POS machine of MAX232C chip, realize the conversion between Transistor-Transistor Logic level and the RS-232, support USB HOST interface and SD flash card.Not only very powerful with the communication of outside expansion, and little process chip directly supports reading of flash card, improves the degree of integration of system greatly.Program extracts the configuration file and the data file that need and moves automatically according to the bibliographic structure of file in the flash card.

The signal that the Audio output port of microprocessor chip is converted to DAB by audio decoder chip CODEC simulation promotes loudspeaker output after power amplifier chip (TDA7496) is sent out greatly.

The digital video signal LCD_D[0:23 that the video signal output of microprocessor chip is 24], the process video conversion circuit is converted to the simulating signal of the VGA of standard, connects the input port of TFT-LCD LCD MODULE again.The video data output terminal of Au2100 microprocessor chip is by data bus LCD_D[0:23 among Fig. 2] the corresponding port of vision signal change-over circuit chip U11 (ADV7123) in the map interlinking 3, and connect the corresponding port of LCD LCD MODULE driving circuit by D-SUB socket J9, and then connect the TFT-LCD LCDs by the output pin 25-36 of this chip.Simultaneously, the video data output terminal of Au2100 microprocessor chip is by data bus LCD_D[0:23 among Fig. 2] video signal transmission circuit chip (DS90C385) in the map interlinking 4, and connect the corresponding port of LCD LCDs by the output pin 37-48 of this chip.Like this, central microprocessor on this POS machine circuit mainboard can adopt the mode of multi-process parallel running, carry out simultaneously by reading in the storage card serial data of multimedia file and POS machine that image video signal is handled and the serial port protocol processing, to be converted to the vision signal of simulation through the digital video signal of image processing engine by the vision signal change-over circuit again, connect the input port of LCD LCD MODULE, realize " alternative " output of vision signal, thereby have more dirigibility and adaptability.

During use, the cash register amount of money, roll titles, video pictures can be incorporated in the same video image, graphics processing engine output port output by microprocessor chip, deliver to ADV7125 DAC chip, convert the standard VGA simulating signal to, exporting the LCD LCD MODULE to, under the driving of driving circuit, when playing corresponding sound, show various video informations such as the cash register amount of money, roll titles or video ads as required by sound equipment.

Present embodiment has video playback POS passenger family display, has overturned existing visitor and has shown notion.Make POS passenger show not only, can issue various information simultaneously as the equipment that amount of money reality simply is provided, and with the mode of literal, picture and video offer the POS cashier's machine towards the client.Its significant advantage is: incorporate mentality of designing, enrich strong functions, and same Circuits System is saved manufacturing cost.Monolithic low-power consumption/high performance multimedia central microprocessor.Upgradeable client's cash register serial communication protocol system supports all POS cashier's machines, and upgradeable system intelligence operating system can be adjusted the layout of display frame according to no application requirements.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
