Abstract
The utility model discloses a quick upgrading circuit of second-generation identification card networking verification equipment. The quick upgrading circuit comprises a TF (TransFLash) card, a data bus transmission circuit, an upgrading file data buffer, a microprocessor and a display screen, wherein the TF card is connected with the data bus transmission circuit through a TF card slot; the output of the data bus transmission circuit is connected with the input of the upgrading file data buffer; the output of the upgrading file data buffer is connected with the microprocessor; and the display screen is connected with the microprocessor through an SPI (Serial Peripheral Interface) bus. When the TF card is inserted into the card slot, whether the TF card comprises effective upgrading files is detected, if so, the upgrading file data is copied into the upgrading file data buffer by a data bus and is called by the microprocessor to finish upgrading, and the upgrading progress is displayed on the LED display screen in the upgrading process. The quick upgrading circuit disclosed by the utility model has the characteristics of simple structure, high upgrading speed, low upgrading cost, convenience for use, capability of ensuring that a user can observe the upgrading progress in real time, and the like.
Description
Technical field
The utility model relates to a kind of China second-generation identity card online checking equipment circuit of upgrading fast.
Background technology
I.D. is the national general a kind of identification card by public security department's distribution; It is the highest to have frequency of utilization; And characteristics such as owning rate is the highest per capita; Along with popularizing of second generation I.D., the use of China second-generation identity card reader has also more and more widely become one of indispensable office appliance in a lot of fields such as public security, work attendance, employee's management, Internet bar's information acquisition.
But the true and false and the typing Certification of Second Generation information of Certification of Second Generation online checking equipment online checking Certification of Second Generation also have comparatively widely and use.Yet; The following dual mode of the many employings of existing China second-generation identity card online checking apparatus upgrading: (1) is sent producer back to and upgraded: maintenance period is longer; Directly influence client's normal use, and need the cost trucking costs not say, also have the risk of device damage in transit; (2) connecting computer upgrades: need the user to be familiar with computation, be familiar with the operation of upgrade software, request for utilization is higher and must connect computer, uses very inconvenient.
The utility model content
The purpose of the utility model is to solve the deficiency of prior art, provides a kind of and accomplishes Certification of Second Generation online checking low-cost China second-generation identity card online checking equipment device upgrade, that updating speed is fast, simple to operate, the easy to use circuit of upgrading fast through the TF card.
The purpose of the utility model realizes through following technical scheme: the China second-generation identity card online checking equipment circuit of upgrading fast; It comprises TF card, data bus transmission circuit, upgrade file data buffer, microprocessor and display screen; The TF cartoon is crossed the TF draw-in groove and is connected with the data bus transmission circuit; The output of data bus transmission circuit links to each other with the input of upgrade file data buffer; The output of upgrade file data buffer is connected with microprocessor, and display screen links to each other with microprocessor through spi bus.
The described display screen of the utility model is a LCD display.
The utility model also comprises a reset circuit, and reset circuit is connected with the reset terminal of microprocessor through bus.
The beneficial effect of the utility model is: when the TF card inserts in the draw-in groove; Check it whether to comprise effective upgrade file; If comprise, then the upgrade file data are copied in the upgrade file data buffer through data bus, call by microprocessor and accomplish upgrading; In the time of upgrading, on LCD display, show the progress of upgrading in real time; Have simple in structurely, updating speed is fast, and upgrade cost is low, but user's Real Time Observation upgrading progress, characteristics such as easy to use.
Description of drawings
Fig. 1 is the utility model structural representation block diagram;
Fig. 2 is the utility model course of work process flow diagram.
Embodiment
The technical scheme of the utility model is described in further detail: as shown in Figure 1 below in conjunction with accompanying drawing; The China second-generation identity card online checking equipment circuit of upgrading fast; It comprises TF card, data bus transmission circuit, upgrade file data buffer, microprocessor and LCD display; The TF cartoon is crossed the TF draw-in groove and is connected with the data bus transmission circuit; The output of data bus transmission circuit links to each other with the input of upgrade file data buffer, and the output of upgrade file data buffer is connected with microprocessor, and LCD display links to each other with microprocessor through spi bus.This circuit of upgrading fast also comprises a reset circuit, and reset circuit is connected with the reset terminal of microprocessor through bus.
As shown in Figure 2; Whether open China second-generation identity card online checking device power supply (DPS), system powers on and gets into UBOOT, have the TF card to insert on the microprocessor check TF draw-in groove; Insert if any the TF card; Then check on this TF card whether comprise effective upgrade file,, comprise and then begin quick upgrading if do not comprise then normal start-up system.The upgrade file data copy in the upgrade file data buffer through the data bus transmission circuit; The upgrade file data that microprocessor calls in the buffer are upgraded; In the time of upgrading, on LCD display, show the upgrading progress in real time, so that the user manages.After upgrading was accomplished, system resetted through reset circuit, restarts system and then accomplishes quick upgrading.
