Abstract
The utility model relates to an intelligent IC card tax controller for an electronic cash register. Transaction data of the electronic cash register every time are obtained through the connection of a serial port and the electronic cash register and are stored in an intelligent IC card; the intelligent IC card is served as the medium of data storage and data transmission to realize the accurate statistics of the transaction data by tax departments consequently to achieve the purpose of tax control. The utility model uses the intelligent IC card which is in accordance with ISO7816 standard, and a bidirectional I/O wire of the card is connected with a single-chip computer via driving; the single-chip computer sends out an APDU command to the intelligent IC according to ISO7816 time sequence to carry out data readout or rewriting operation.
Description
The utility model relates to a kind of tax-controlling device of being made up of intellective IC card and 89F5 * single-chip microcomputer that is used for electronic cash register.
In the present prior art, all kinds of electronic cash registers as taximeter, electronic scales etc., can't provide the data recording of each transaction for revenue department, and therefore, revenue department can't obtain the foundation of tax revenue from electronic cash register itself.The utility model is to design for head it off.
The purpose of this utility model is that a kind of tax-controlling device will be provided, and it can for revenue department provides whole transaction data, thereby realize tax control function with each transaction data of intellective IC card recorded electronic taximeter.
The purpose of this utility model is achieved in that by 89F5 * serial port of single chip computer of this device and electronic cash register communication, the data of at every turn being concluded the business write these data in the intellective IC card, simultaneously at 89F5 * middle formation accumulated value.Intellective IC card and 89F5 * storer be FLASH EEPROM, therefore, data can not lost after system's power down.Intellective IC card is as the media of data storage and transmission, and data transfer is to the tax revenue basis of revenue department as the electronic cash register operator; 89F5 * in aggregate-value then become the reservation ledger as checking data.
The utility model need be installed in the general electronic cash register and use, and it links to each other by serial port with electronic cash register.Its 89F5 * CPU connects two intellective IC cards, is respectively external smart IC-card and inner SIM authentication card.The former is used to write down electricity in the transaction data of taximeter; And deposit the encrypting and authenticating information of revenue department among the latter, and be used for the external smart IC-card that inserts is authenticated, be the legal intellective IC card of revenue department's distribution to guarantee it.89F5 * the P1 mouth link to each other with external smart IC-card interface, the P3 mouth links to each other with inner SIM authentication card, according to the sequential of intellective IC card ISO7816 prescribed by standard, 89F5 * CPU carries out writing or reading of data to two intellective IC cards.
The circuit structure of utility model and concrete circuit are provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the electrical block diagram according to the electronic cash register intellective IC card tax-controlling device that the utility model proposes.Fig. 2 is concrete schematic circuit.Below in conjunction with Fig. 1,2 details and the working conditions that describe in detail according to the concrete device that the utility model proposes.
This intellective IC card tax-controlling device mainly comprises: center control section (1) (U1 89F58 single-chip microcomputer): external smart IC-card part (2) (CARD) is used for the transaction data of recorded electronic taximeter; External smart IC-card interface drive part (3) (U2A～D, 7407); Inner SIM authentication card portion (4) (SIMCARD) is used to authenticate the external smart IC-card; Inner SIM authentication card drive part (5) (U2E, F, 7407); Intellective IC card clock part (6) is used for providing CLK clock signal to two IC-cards; Electronic cash register interface (7) (J1) is used for this device is linked to each other with electronic cash register.
Intellective IC card is the IC-card that has CPU, and its interface meets the ISO7816 standard, and the interface data line is the I/O bidirectional lines, after two doors through 7407 drive, is divided into two unidirectional lines and links to each other with 89F58 interface microcontroller line, carries out serial data transmission.According to the sequential of ISO7816 prescribed by standard, 89F58CPU sends the APDU order to two intellective IC cards respectively, and two IC-cards are carried out writing or reading of data.
Claims (4)
1. intellective IC card tax-controlling device that is used for electronic cash register, this device is made up of a single-chip microcomputer (U1), two intellective IC cards (CARD and SIMCARD) and an electronic cash register interface (J1), and the P1.4 that it is characterized in that single-chip microcomputer (U1) and P1.5 link to each other with the I/O line of external smart IC-card (CARD) by two doors of 7407; The P3.4 of single-chip microcomputer (U1) and P3.5 link to each other with the I/O line of internal authentication card (SIMCARD) by two doors of 7407; Single-chip microcomputer is read and write two IC-cards respectively by these lines.
2. device according to claim 1 is characterized in that employed intellective IC card is the IC-card that meets the ISO7816 standard, by bidirectional interface line I/O, links to each other with single-chip microcomputer (U1) through 7407 drivings.
