Description

Internet bar's non-contact ID/IC-card computing machine charging control device

Technical field:

The utility model relates to a kind of charging control device, especially relates to non-contact ID/IC-card Computer Control Unit that a kind of Internet bar system of real name charge system is used.

Background technology:

At present, the Internet bar charges and generally adopts two kinds of methods: a kind of is to scattered client, is chargeed to the initial sum termination time of computing machine input client ID (identity number) card information, online by the operator; A kind of is to the member system client, adopts Contact Type Ic Card to locate to swipe the card charging the operator.These two kinds of charging methods can not be chargeed scattered client and member system client unification in the mode of swiping the card, be unfavorable for the operation control of Internet bar, and during the Internet Cafe Charging System operation irregularity, can't shut down by force to computing machine, cause expenses of surfing in Internet to run off, simultaneously, a kind of charging method in back can only be operated at the operator place of the total platform in Internet bar, can not carry out man-to-man management to computing machine.

The utility model content:

Technical problem to be solved in the utility model provides a kind of easy and simple to handle, non-contact ID/IC-card computing machine charging the control device that utilizes Internet bar's operation control is arranged, this device adopts non-contact ID/IC-card mode of swiping the card, when client registers, in the ID/IC card, write user identity card information by the operator, also can in IC-card, write relevant metering data, client can be stuck in any enterprising line operate of computing machine that this device is installed in the Internet bar, the charge system that its ID (identity number) card information and surf time information enter the Internet bar automatically whereby.

The technical solution of the utility model is: comprise ID/IC card and ID/IC card reader, the ID/IC card reader is made up of read chip and control chip, the read chip is used for received RF signal, the radiofrequency signal of reading in is carried out data demodulates, output to control chip then, simultaneously to modulating to the data that IC-card writes, emitting radio frequency signal then, write to IC-card, control chip is used for the manchester encoded data of read chip output is decoded, and decoded binary data information transmits by the charge system of serial ports in PC; Write the data of IC-card, be sent among the ATmega48V by serial ports,, be transported to the read chip then and modulate and launch, write to IC-card again by ATmega48V coding by the charge system in the PC; When the charge system operation irregularity, the shutdown of control chip control PC.

The utility model is compared with existing Internet bar charging method, has following advantage:

(1) adopt non-contact ID/IC-card mode of swiping the card, easy and simple to handle, the management of can on each computing machine of Internet bar, swiping the card;

(2) adopt this device, can charge in the mode of swiping the card scattered client and member system client are unified, the present situation that has changed two kinds of charging methods in the background technology and deposited helps the operation control of Internet bar;

(3) this device is installed on each computing machine of Internet bar, no matter which platform online client uses, all under the control and management of charge system, its ID (identity number) card information and surf time enter Internet bar's management system automatically, and between a plurality of Internet bars of the same charge system that this device is installed, client can be with the free internet access of ID/IC card;

(4) when the Internet Cafe Charging System operation irregularity, this device can shut down by force to computing machine, avoids causing expenses of surfing in Internet to run off.

Description of drawings:

Fig. 1 is a structured flowchart of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment:

With reference to Fig. 1, the utility model comprises ID/IC card and ID/IC card reader, the Card Reader operation is carried out ID and IC-card, the ID/IC card is placed in the antenna magnetic field scope, approximately within the antenna 15mm, responded to by the antenna radio-frequency (RF) magnetic field, in the ID/IC card, produce working power, and the beginning emitting radio frequency signal, transmit data to the ID/IC card reader.

The ID/IC card reader is made up of read chip and control chip, and the read chip is used for received RF signal, and the radiofrequency signal of reading in is carried out data demodulates, then manchester encoded data is outputed to control chip; The data-modulated that need write to IC-card writes to IC-card on radio-frequency carrier.Control chip is used for the manchester encoded data of read chip output is decoded, and decoded binary data information transmits by the charge system of serial ports in PC; Write the data of IC-card, be sent among the ATmega48V by serial ports,, be transported to the read chip then and modulate and launch, write to IC-card again by ATmega48V coding by the charge system in the PC; The shutdown of control PC appears when unusual in charge system work.

With reference to Fig. 2, the radiofrequency signal that the ID/IC card reader receives, from the 4th pin input of U2270B, after the demodulation via U2270B, the manchester encoded data that obtains is exported by the 2nd pin.Manchester encoded data is input to control chip from the 12nd pin of ATmega48V, through decoding, obtains the binary data of ID/IC card information, and data are exported from the 31st pin, and the charge system of the 1st pin in PC via the serial ports socket transmits again.

Writing operation carries out IC-card, write the data message of IC-card, charge system from PC is sent to serial ports socket the 2nd pin of this device via serial ports, signal is sent into control chip ATmege48V the 30th pin, after in chip, encoding, from the output of the 13rd pin, send into read chip U2270B the 6th pin; When using the ID card, the 6th pin of U2270B connects power supply 5V circuit through resistance R 8.Coded signal is modulated in U2270B on the radio-frequency carrier, is added in antenna ends by the 8th pin, the 9th pin then, produces radio-frequency (RF) magnetic field.Be subjected to radio-frequency (RF) magnetic field induction, receive radiofrequency signal in the IC-card,, obtain data message and store, finish the write operation process through demodulation.
