Shown in flow chart Fig. 6 of the proving program of card.The algorithm of the checking routine of used card is shown in testing for Fig. 7 cards Card routine is described in figure, and the checking routine of Fig. 6 cards is carried out in following sequence.The card reset command sends (25).Answer Position response (ATR) order from clamping receive and with the ATR (26) of storage.20 answers that ought be received are to be the discovery that correctly, card Security setting examined validity and correctness (27).When the answer received is not to be the discovery that correctly the card has Effect property is checked and blocked invalid (30).Card will be identified, and it is dead card to release

The safety method of security setting (code) basis, such as one of DES-3, exchanged by the support of the smart card (27) and logical Meter and smart card respectively are crossed, is checked.When security setting (code) is correct, the sequence number (SN) of meter and card number code is by from card (29) Read.When 5 security settings (code) be it is incorrect, it be examined with find detect card crash whether be detect first card Event of failure (28).When the card failure detected is the first card failure event for detecting, the card is reset (25).When detecting Card failure be not for the first time detection card break down, then the card it is invalid or card be revoked.Card will be identified and draw Enter as dead card (30).

Card number is read for identifying copy card, if applicable (29).Card will be identified and introduce as dead card (30).The sequence number of the sequence number of ammeter and the card read from card examined correctness and reliability (31).It is correct when finding From card read instrument sequence number, then from card read card sequence number with from instrument read inspection correctness (34) sequence number of card 15 compares.When the sequence number of the card for the sequence number reading that card is read from card and from ammeter is identical , it is judged as effective credit card in card.When the sequence number not phase that the card that the sequence number of card is read is read from card and from ammeter Together, then card is considered as expired and is deactivated.

When finding the incorrect sequence number that instrument is read from card, then the sequence number of the instrument is checked, with look-up table Sequence number whether be equal to it is set in advance value (32).When the sequence number of instrument is equal to preset value, then the sequence number blocked is carried out Check whether be equal to zero in the value of instrument card number with discovery or do not have.When card number value be equal to zero, the card is identified as neocaine. The card is judged as first and effectively card (33).When the value in instrument card number is equal to zero, the card is accepted as first card of meter Piece.The algorithm of oneself it can be assigned to without others card except copy card after instrument.When the value in instrument card number In zero, then the sequence number blocked is checked, with find to the sequence number of card whether correctness (35).When the value in instrument card number It is found to be correctly not equal to zero, and in the sequence number of card, then card is designated as a duplicate card and is considered as effective with card Card.When the value in instrument card number is not equal to zero, and it is found to be incorrect in the sequence number of card, it is invalid that the card is judged as Card.When the sequence number of instrument is not equal to preset value, then card is considered as dead card.

Fig. 7 shows the flow chart of the data transfer process between card based on 15.Carried out in following sequence Data transmission procedure between meter and card.The card is examined to find whether the card is the first card or copy card (36).When card quilt It is the discovery that first card or copy card, then acquired and data that are calculating are written into card.When card be not the first card or Not copy card, card data are read (37).The credit value being stored in card is read and checked, to find stored credit value Whether be on the occasion of or do not have.When the credit value stored in the card is to be kept on the occasion of remaining credit, remaining credit value, and in card Credit be added to the credit datas of instrument (38).Next credit interval is displaced in the remaining credit value of card.It is residual Remaining credit is added to new credit (being specified in card) and is stored as result to count new credit.When the credit value stored is In the negative residual credit of instrument, remain in card this negative credit and be ignored, remain in meter credit and be set equal to remaining card (39) credit.Then, new credit (being specified as blocked) is stored as increasing credit newly in instrument.Whole data include electrically with hydraulic pressure joining Number is transferred and recorded in card (40) from instrument card.
