Abstract
The device belongs to an IC card reader-writer which is used for connecting a computer. The device is composed of a main controller, a communication interface circuit, a converter, a power supply, a power supply monitor and a socket connected with the computer and an IC card, wherein, the main controller is taken as a core which is connected with the computer through the interface circuit and the converter; the readout and the input of the data of the IC card are switched by a converting circuit, and the data are serially inputted or outputted to the computer through the interface circuit. The utility model has simple structure, the controller CPU is taken as the core to collect various data, and has the advantages of high speed and good versatility and is the advanced IC card reader-writer.
Description
The utility model relates to a kind of and the IC-card data acquisition unit computing machine coupling, is fit to do various data acquisitions and uses.
At present, a lot of with the IC-card data acquisition unit kind of computing machine coupling, generally mostly being data-storing uses, desired data is imported from computing machine, have independent interface to connect with computing machine, data are deposited in behind the IC-card in that needed data computing is machine-readable again, this kind IC-card interface is general common version, simple in structure, the data-storing amount is limited, function singleness, and interface circuit is also simpler, its weak point is that this kind IC-card function of reading is limited, for mass data, need rough handling to read and write by computing machine again and be difficult to realize the lack of wisdom function, be difficult to use in some complicated technology fields, make troubles for scientific research or work.
For solving the deficiency of above IC-card read-write, the purpose of this utility model provides a kind of intelligent card data collector, has data processing function, utilizes cpu chip, has solved the read-write effect of present IC-card effectively.
The structural design of the utility model is achieved in that its circuit structure is by master controller, the communication interface circuit, converter and power supply and power supply supervisory circuit are formed, the socket that connects with computing machine and IC-card, its connection is to be core with the master controller, computing machine connects with communication interface MAX232 by combination hub RJ45,232 interface circuit input and output connect with master controller 89C2051 (with flatly) by converter MAX393, when converter connected with master controller, its output terminal was by forward and reverse OC gate circuit driver U
5ICC connects with the IC-card deck, and connecting with deck has clock circuit simultaneously, and the power supply of this intelligent card data collector is made up of two parts, and the power supply of supplying with main control circuit is M
1Power module, the power supply of supplying with IC-card is M
2, the MC78L05CP module, controller connects with it Power Monitoring Unit MAX simultaneously
Q* 809.
The utility model has following advantage compared with the prior art: simple in structure, adopting controller CPU is that core can be finished various data collection tasks, and processing power is strong, and speed is fast, and versatility is good, and working stability is reliable, is a kind of comparatively advanced IC-card data acquisition unit.
The detailed structure of the utility model is provided by embodiment and accompanying drawing.
