Description

Campatible IC-card data collection processor

The utility model belongs to a kind of IC-card read-write equipment.

At present, IC-card is widely used, especially in some banks, the tax, the transmission of the information data of all departments of public institution or storage are indispensable, because connecting, IC-card and computing machine use, more there is it quick, characteristic of accurate, general general IC-card read write line all is for certain specific I C card, functions of use is single, version is simple, can not compatiblely use, and a kind of read write line is only to a kind of IC-card, and software is identical, this kind read write line is simple in structure, and is easy to use, but its deficiency is a poor compatibility, it is not routine to bring for the use of multiple IC-card, has reduced effective utilization of IC-card.

For solving the deficiency of above IC-card read write line, the utility model provides a kind of compatible IC-card data collection processor, utilizes the full master controller of multi-functional IC-card combination hub control function, to reach the purpose of the compatible read-write of IC-card.

The structure of the utility model is achieved in that its circuit structure of this data collection processor is by master controller, data buffer, memory, RS-232 interface circuit and multi-functional IC-card combination hub are formed, circuit is provided with power supply and monitoring power supply, it is to be core with the master controller that its circuit connects, master controller U ₁With data bus through data buffer U ₃With memory U ₂The corresponding connection; While master controller U ₁Direct and the memory U of data bus ₂Connect master controller U ₁Address bus connects with data buffer is corresponding with memory respectively, and control line directly connects with memory, master controller U ₁ Opposite side 6 output lines are direct and IC-card combination hub U through reverse driven ₉Output terminal connects, combination hub U ₉Be 416CAD, have 1/D, CLK, RST, PROG, each control signal union end of FUS and NC, it is clamped through resistance output that the reverse driven back is connected to power supply, and the output of master controller one output terminal is amplified driving power 78L05 by combination hub U through diodetriode ₉Output is controlled power light LED, combination hub U respectively through the output of two triodes simultaneously ₉I/O end through reverser U ₄With master controller U ₁One of in fracture join, control U ₁Work, master controller U ₁The RT output terminal directly and the corresponding end of ICL232 interface join, the output of interface is joined through socket and computing machine serial input port, this machine is provided with power circuit ,+12V is through power module U ₇Output DC is flat to be used for full thermomechanical components, is provided with monitoring power supply U simultaneously ₆, its output connects the reset terminal of master controller.

During work, this machine joins by serial communication interface with computing machine, behind the insertion IC-card, by computing machine it is read and write, and has adopted compatible six good line IC-card combination hubs on electrical structure, has realized the function to the compatible read-writes of all IC-cards.

The structure of the utility model is provided by embodiment and accompanying drawing.

Fig. 1 is a Campatible IC-card data collection processor electrical schematic diagram;

Circle 2 is a Campatible IC-card data collection processor electrical schematic diagram;

Circle 3 is a Campatible IC-card data collection processor power supply electrical schematic diagram;

Its circuit structure is by shown in the accompanying drawing, and used device is as follows: master controller U ₁Be 8031, data buffer U ₃Be 74HC373, memory U ₂Be 27C64/128, communication interface U ₈Be ICL232, IC-card combination hub U ₉Be 416CAD, power module U ₇Be 7805, monitoring power supply U ₆Be TL7705, the driving power triode is 8050 and 90134, and power module 78L05 presses socket output reverser U ₄Be 74HC05.

Fig. 1, a of Fig. 2, b, the corresponding connection of c are the total electrical schematic diagram of processing.

This circuit structure is that the output interface of IC-card connects by serial line interface with computing machine, when IC-card inserts on the IC-card combination hub, by computing machine the data on the IC-card are read and write, general IC-card has simple function, only a kind of data are read and write processing, but this kind IC-card has compatibility function, all can read and write by computing machine various types of data, tool has an enormous advantage, because of its IC-card structure has adopted master controller U ₁Be that 8031 effects add that according to impact damper, memory the communication interface function is complete, realized the compatible function of reading of all IC-cards.
