With reference to figure 3-5, at this, suppose public transport 387 tunnel (also can be the traffic route of rail line or similar system here) by way of the station Beijing West Railway Station (A) is arranged, revives door station (B), station, Xizhimen (C) and station, Qinghe (D), consider that this public transport 387 tunnel stop to have a rest the back from Qinghe (D) at the station, Qinghe, by way of station, Xizhimen (C), revive door station (B) and get back to Beijing West Railway Station (A).As shown in Figure 3, regard once coming and going of public transport 387 tunnel as a circuit, i.e. A-B-C-D-D-C-B-A, and this bus will repeat above-mentioned driving route.For the purpose of simplifying the description, now to each station serial number, then become 1-2-3-4-5-6-7-8, each numbering all corresponding a concrete station physically, at this, with the last leg is that the 8th station is as the supposition terminus, generate the cost information at (i.e. 1 to 8 station) this supposition terminus (the 8th station) of getting on the bus in advance from each station, promptly get on the bus from the 1st station, suppose predesigned end point promptly the expense of the 8th station correspondence be 1.24, the corresponding expense of getting on the bus from the 2nd station is 1.0, the corresponding expense of getting on the bus from the 3rd station is 0.83, getting on the bus from the 4th station, (in fact the 4th station is a terminal station, have only the people to get off and have no talent and get on the bus, also can be understood as the expense at the 8th station of getting on the bus from the 4th station) corresponding expense is 0.62, the corresponding expense of getting on the bus from the 5th station is 0.62, the corresponding expense of getting on the bus from the 6th station is 0.4, the corresponding expense of getting on the bus from the 7th station is 0.2, getting on the bus from the 8th station, (in fact the 8th station is a terminal station, have only the people to get off and have no talent and get on the bus, also can be understood as the expense at the 8th station of getting on the bus from the 8th station) corresponding expense is 0.General bus all is to split simultaneously, and is therefore corresponding with station from A to D, has simultaneously and opens 387 road vehicles of standing to A from the D station.For the vehicle that this is split, it has become 5-6-7-8-1-2-3-4 by way of the Station XXX sequence, here suppose still that the 8th station is the terminus, the same cost information at (i.e. 1 to 8 station) the 8th station of getting on the bus that uses above-mentioned generation from each station, promptly get on the bus from the 5th station, suppose predesigned end point promptly the expense of the 8th station correspondence be 0.62, the corresponding expense of getting on the bus from the 6th station is 0.4, the corresponding expense of getting on the bus from the 7th station is 0.2, the corresponding expense of getting on the bus from the 8th station is 0, and the corresponding expense of getting on the bus from the 1st station is 1.24, and the corresponding expense of getting on the bus from the 2nd station is 1.0, the corresponding expense of getting on the bus from the 3rd station is 0.83, and the corresponding expense of getting on the bus from the 4th station is 0.62.
When passenger's first from the 2nd station when getting on the bus, first is at vehicle-mounted inlet IC-card read write line place brush IC-card, this vehicle-mounted inlet IC-card read write line is deducted above-mentioned corresponding cost 1.0 from IC-card, and in IC-card, writing inception point, starting time, train number 387 and (first) riding information such as deduct the fee, first riding information can comprise all or part of information that exemplifies here.Help like this finding whether passenger's the interior remaining sum of card may enough pay, if can not enough pay, can take alternate manner to cover the loss such as artificial mode of collecting the charges, help like this shortening the dwell time, avoid charge hastily again behind the vehicle pull-in, and can avoid the loss of stealing a ride.In addition, for example can write the IC-card read write line by existing sound broadcast system triggers and with the vehicle information of arriving at a station by steward or driver, can certainly by steward or driver directly by input media for example button trigger and the vehicle information of arriving at a station accurately read to be used for subsequent treatment from the storage unit of read write line, perhaps can opening by the sensor car door or/and close with this and trigger aforementioned read operation, certainly consider that car door may repeatedly open and close at a station, this can judge whether to trigger by the mistiming of closing the door action and open the door between the action next time, for example, when this mistiming is in 30 seconds, do not trigger, when it then triggers during more than or equal to 30 seconds, this mistiming can be set according to the different situations of reality, it for example can be 10 seconds, it also can be 40 seconds, preferably at 5-60 between second.
When the passenger gets off, the place swipes the card at vehicle-mounted outlet IC-card read write line, the IC-card read write line optionally reads starting point, starting time, card number, remaining sum in the card, information such as starting point deducts the fee, when having relevant information records such as starting point deducts the fee in the IC-card sheet, inquiry is handled to small change expense that should endpoint information and to relevant informations such as the starting point in the IC-card sheet deduct the fee, for example delete or give a certain parameter zero setting etc., as long as can be as judging whether the foundation of small change, any processing can, this is in order to realize for pre-payment each time, only do small change one time, overcharge the expense of getting for passenger's small change simultaneously, in addition, for example can be with card number, starting point, starting time, remaining sum in the card, starting point deducts the fee, terminal point small change expense, terminal point, riding informations such as terminal time (riding information of origin-to-destination) store in the storage unit of read write line, for follow-up clearing, clearance, the use of inquiry etc.Particularly, when passenger's first was got off at the 3rd station, the small change expense was 0.83 (i.e. the expense of the 3rd station correspondence).At this, each station (1-8 station) that for example can store aforementioned formation in vehicle-mounted inlet IC-card read write line and vehicle-mounted outlet IC-card read write line is to the cost information database of supposition terminus (the 8th station), and realizes charge to the user by aforesaid starting point deduction and terminal point small change.Certainly, the present invention is not limited to this, for example also can vehicle-mounted outlet IC-card read write line store each station (1-8) stand between possible various pay imformations, expense such as the 2nd to the 3rd station, and when the passenger swipes the card at vehicle-mounted outlet IC-card read write line place, deduct the fee and the expense at the 2nd to the 3rd station calculates terminal point small change expense by starting point, and the user is carried out small change.In addition, acousto-optic hint or led display unit are shown to the user with the information of necessity such as remaining sum in the card.
As mentioned above, the cost information of being stored in vehicle-mounted inlet IC-card read write line and the vehicle-mounted outlet IC-card read write line is identical, also all is to be used for inquiry.
For the riding information data of storing in the vehicle-mounted outlet IC-card read write line, can be regularly such as gathering by the infrared harvester or the jumbo IC-card that are easy to carry about with one every day, and be transferred to Bus Card subsystem settlement center or track traffic smart card subsystem settlement center, all-purpose card liquidation center by acquisition station.
Therefore most of identical among embodiment 2 and the embodiment 1, omitted same section at this, only different parts is described in detail.
Since among the embodiment 1 all the time with the 8th station as the supposition terminus, therefore, when vehicle-mounted inlet IC-card read write line deducts the fee, the expense of being deducted is greater than the actual expense that will pay of passenger all the time, and this may cause also having in the card user of 0.62 yuan of remaining sum can't use the IC-card defrayment when get on the bus in the 1st station.In order to alleviate this problem, the invention provides a kind of optimal way.
With reference to figure 3-5, at this, suppose public transport 387 tunnel (also can be the traffic route of rail line or similar system here) by way of the station Beijing West Railway Station (A) is arranged, revives door station (B), station, Xizhimen (C) and station, Qinghe (D), consider that this public transport 387 tunnel stop to have a rest the back from Qinghe (D) at the station, Qinghe, by way of station, Xizhimen (C), revive door station (B) and get back to Beijing West Railway Station (A).As shown in Figure 3, regard once coming and going of public transport 387 tunnel as a circuit, i.e. A-B-C-D-D-C-B-A, and this bus will repeat above-mentioned driving route.For the purpose of simplifying the description, now to each station serial number, then become 1-2-3-4-5-6-7-8, each numbering all corresponding a concrete station physically, at this, in fact the 4th station and the 8th station all are the terminus, as shown in Figure 5, when physically terminus (the 4th station and the 8th station) of supposition when being the terminus, generating cost information and 8 stations, the 5th station to that the from the 1st to 4 station is respectively the 4th station to the predesigned end point station in advance is the cost information at the 8th station to the predesigned end point station respectively, and is stored in the storage unit of IC-card read write line.Particularly, get on the bus from the 1st station, suppose predesigned end point promptly the expense of the 4th station correspondence be 0.62, the predesigned end point of getting on the bus from the 2nd station i.e. expense of the 4th station correspondence is 0.38, the predesigned end point of getting on the bus from the 3rd station i.e. expense of the 4th station correspondence is 0.21, the predesigned end point of getting on the bus from the 4th station i.e. expense of the 4th station correspondence is 0, the predesigned end point of getting on the bus from the 5th station i.e. expense of the 8th station correspondence is 0.62, the predesigned end point of getting on the bus from the 6th station i.e. expense of the 8th station correspondence is 0.4, the predesigned end point of getting on the bus from the 7th station i.e. expense of the 8th station correspondence is 0.2, the predesigned end point of getting on the bus from the 8th station i.e. expense of the 8th station correspondence is 0 (in fact only have under the people at the 4th station and the 8th station, and on nobody).General bus all is to split simultaneously, and is therefore corresponding with station from A to D, has simultaneously and opens 387 road vehicles of standing to A from the D station.For the vehicle that this is split, it has become 5-6-7-8-1-2-3-4 by way of the Station XXX sequence, here still supposition terminus (the 4th station and the 8th station) physically is the terminus, the same cost information at (i.e. 1 to 8 station) get on the bus the 4th station or the 8th station that uses above-mentioned generation from each station, promptly get on the bus from the 5th station, suppose predesigned end point promptly the expense of the 8th station correspondence be 0.62, the corresponding expense of getting on the bus from the 6th station is 0.4, the corresponding expense of getting on the bus from the 7th station is 0.2, the corresponding expense of getting on the bus from the 8th station is 0, the corresponding expense of getting on the bus from the 1st station is 0.62, the corresponding expense of getting on the bus from the 2nd station is 0.38, the corresponding expense of getting on the bus from the 3rd station is 0.21, and the corresponding expense of getting on the bus from the 4th station is 0.
By being stored in this database in the storage unit, can solve the problem that begins to mention effectively.Promptly, generate each station and the first supposition terminal point 4 or second expense of supposing between the terminal point 8 in advance by serving as the supposition terminal point with physically terminus respectively.

As the method for being analyzed in embodiment 1 or 2, can be implemented in the prepayment IC-card read write line that uses identical configuration on the public bus network, (if vehicle-mounted small change IC-card read write line, a circuit can use identical vehicle-mounted small change IC-card read write line so equally also can to use the small change IC-card read write line of roughly the same configuration; For the small change IC-card read write line of station, significantly, station number information difference, the configuration that is to say the station number parameter is different).But actual situation may not be to charge to the distance of starting point according to terminal point, for example, has starting to charge, or the generation of various situations such as ceiling price.Below will describe the solution of these problems in detail.
For example, being arranged on the station with small change IC-card read write line is example, but be not limited to the situation of this embodiment, No. 725 bus starting fare a=1 units, 0.1 yuan of every kilometer unit price (starting fare a also has 2 yuan situation certainly, and then every kilometer unit price is with 0.2 yuan of calculating), ceiling price b=1.8 unit (can certainly price limit 1.5 or 3.0 yuan etc., can differently be provided with according to the needs of actual conditions), station along the line comes and goes and amounts to 30.For example the physical end station is the 14th and the 30th station, suppose 1-14 stand supposition terminal point the 14th station distance, suppose that distance that the 15-30 stop spacing supposes terminal point the 30th station as shown in Figure 8, only is accurate to 1 kilometer at this, can certainly be more accurate.
At this, with every kilometer 0.1 yuan of calculating, 20 kilometers altogether, maximal value is 2 yuan, suppose regulation starting fare a=1.0 unit, 1.8 yuan of ceiling prices (also can for 2 yuan etc.), and past journey (the 1st to the 14th station) check code is A, return (29 stations, the 15th station to the) check code is B.At this, as long as check code (being called for short the inspection sign indicating number) past, that return distinguishes just passable.
According to the raw data among Fig. 8, with 0.1 yuan every kilometer is unit price, generate corresponding expense and the check code information table (as shown in Figure 9) in every station in advance, and it is stored in the storage unit of prepayment IC-card read write line and small change IC-card read write line, and parameter informations such as train number 725, starting fare a=1.0 also are stored in the lump in the storage unit of prepayment IC-card read write line; Also store starting price a=1.0, ceiling price b=1.8, train number 725, car station number parameter informations such as (immobilizing) in the small change IC-card read write line AT STATION simultaneously.For example the car station number in the station small change IC-card read write line at the 13rd station is always 13.At this, the relevant information that can store many circuits in the storage unit of this station small change IC-card read write line, for example except 725 times, also stored the relevant information of air-conditioning 727 tunnel, such as parameters such as train number 727, starting price a=2.0, ceiling price b=7.0, car station number 5, expense, check codes.
When under the supervision of passenger the steward when pre-payment is got on the bus at the 2nd station, pre-payment x from IC-card, x=max (cost information at the 2nd station, a)=max (1.9,1.0)=1.9 yuan, at this, the pre-payment number of times is not done any qualification, and the passenger that the steward should initiatively accuse swipes the card once only, many brushes are pre-payment repeatedly, and prepayment IC-card read write line to information (first riding information) such as major general's train number 725, check code A, pre-payment x are recorded in the IC-card simultaneously; Because the expense of deduction is more than or equal to the riding fee usefulness of reality, steward's active this moment prompt passengers is got off and must initiatively be removed the station small change; For example when the passenger gets off small change at the 14th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code mates, whether there is not small change, mate at train number, check code coupling and do not have also that (the judgement order here can be adjusted under the situation of small change, also can judge simultaneously), according to pre-payment x=1.9, terminal charge 0 (our station i.e. the expense of the 14th station correspondence), starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=1.9-min{max[(1.9-0), 1.0], 1.8}=1.9-min{1.9,1.8}=0.1, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
For example, when the passenger when get on the bus in the 20th station, check code is B, pre-payment x=max (cost information at the 20th station, a)=max (1.3,1.0)=1.3; When getting off at the 24th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code B mates, whether there is not small change, mate at train number, check code mates and does not also have under the situation of small change, according to pre-payment x=1.3, expense 0.8, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=1.3-min{max[(1.3-0.8), 1.0], 1.8}=1.3-min{1.0,1.8}=0.3, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
For example, when the passenger when get on the bus in the 8th station, check code is A, pre-payment x=max (cost information at the 8th station, a)=max (0.8,1.0)=1.0; When getting off at the 9th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code A mates, whether there is not small change, mate at train number, check code mates and does not also have under the situation of small change, according to pre-payment x=1.0, expense 0.8, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=1.0-min{max[(1.0-0.8), 1.0], 1.8}=1.0-min{1.0,1.8}=0.0, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
The present invention is not limited to above-mentioned preferred embodiment, for example can remove in the present embodiment about the content of check code, and such technical scheme also can satisfy actual demand.In addition, for vehicle-mounted outlet small change IC-card read write line, because the car station number can as one man change (being that the car station number changes) with the car station number in the vehicle-mounted prepayment IC-card read write line, so in vehicle-mounted outlet small change IC-card read write line, need to store complete cost information and check code table, to be used to providing different stations corresponding data message, in this case, just do not need to judge whether train number has mated yet, because be on same bus, so train number must mate, in addition, can remove the related content of check code equally.
In addition, for track traffic, inlet pre-payment and outlet small change IC-card read write line all are not move, and promptly their station number is fixed, so, with such scheme similarly, can realize the track traffic smart card subsystem with simple proposal more.
When under the supervision of passenger the steward when pre-payment is got on the bus at the 2nd station, pre-payment x from IC-card, x=max (the cost information at the 2nd station, a)=max (1.9,1.0)=1.9 yuan, at this, the pre-payment number of times is not done any qualification, the passenger that the steward should initiatively accuse, swipe the card only once, many brushes are pre-payment repeatedly, and prepayment IC-card read write line to information (first riding information) such as major general's train number 725, check code A, inception point are recorded in the IC-card simultaneously, at this, increased inception point information in the first information and removed prepayment information; Because the expense of deduction is more than or equal to the riding fee usefulness of reality, steward's active this moment prompt passengers is got off and must initiatively be removed the station small change; For example when the passenger gets off small change at the 14th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code mates, whether there is not small change, mate at train number, check code coupling and do not have also that (the judgement order here can be adjusted under the situation of small change, also can judge simultaneously), according to starting point is the expense 1.9 at second station, terminal charge 0, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, y=max (starting point expense, a)-and min{max[(starting point expense-terminal charge), a] and, b}=1.9-min{max[(1.9-0), 1.0], 1.8}=1.9-min{1.9 1.8}=0.1 is at this, the starting point expense by from the cost information table of storage, obtain (this with embodiment 6 in be different, be to obtain among the embodiment 6 by first riding information in the IC-card), simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
Similarly, when the passenger when get on the bus in the 8th station, check code is A, pre-payment x=max (cost information at the 8th station, a)=max (0.8,1.0)=1.0; When getting off at the 9th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code A mates, whether there is not small change, mate at train number, check code mates and does not also have under the situation of small change, according to starting point expense 0.8, terminal charge 0.8, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, y=max (starting point expense, a)-and min{max[(starting point expense-terminal charge), a] and, b}=max (0.8,1.0)-min{max[(0.8-0.8), 1.0], b}=1.0-min{1.0,1.8}=0.0, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
More simply and since the station number of each concrete station small change read write line for example the 4th station be changeless, therefore, can be 1.6 and the check code B that stores the 4th station correspondence in advance simply, improve the efficient of system more.
In addition, for the ease of statistics, prepayment IC-card read write line numbering also can be stored in the riding information record.In addition, can directly add up income by the pre-payment and the small change information of final storage in the small change IC-card read write line.Certainly, also can add up income according to the small change sum in sum of the pre-payment in the prepayment IC-card read write line and the station small change IC-card read write line.
By top system and method, can realize and level and smooth combination of existing public transport charge system, and also can select to remove according to the by bus mileage charge of reality the regulation of starting fare, ceiling price, in fact, the system that removes after these regulations is higher with efficient.
In addition, for vehicle-mounted small change IC-card read write line, just there is not the problem of check code coupling and train number coupling, and can realize the scheme of starting fare or ceiling price similarly with said method.
Among the embodiment 6 and 7, for small change, all the time more than or equal to zero.Can be perceived under which kind of situation small change by the user so inevitably is to be zero, and particularly for user on and off duty, what they took is identical circuit, and easier grasp rule just causes user's initiatively small change of being unwilling.In embodiment 8, all the time greater than the system of minimum small change value d, d＞0 for example is that minimum small change value d equals 0.1,0.5,0.8,1.0 with a kind of small change of explanation, and this can be provided with voluntarily according to concrete needs, certainly, has been exactly the situation of embodiment 7 when d=0.Be that example is elaborated below with d=1.0.
As shown in accompanying drawing 13, according to minimum small change value d, every kilometer unit price, to distance (only being accurate to kilometer) the generation expense and the check code information table of supposition terminal point at this, promptly all added d on the data of Fig. 9, for example first stop is 2.0 in Fig. 9, and has become 3.0 in Figure 11.In the present embodiment, with the information table among this information table replacement embodiment 6 or 7.
For example, when under the supervision of passenger the steward when pre-payment is got on the bus at the 2nd station, pre-payment x from IC-card, the cost information at x=max[the 2nd station, (a+d)]=max (2.9,2.0)=2.9 yuan, at this, the pre-payment number of times is not done any qualification, the passenger that the steward should initiatively accuse, swipe the card only once, many brushes are pre-payment repeatedly, and prepayment IC-card read write line to information (first riding information) such as major general's train number 725, check code A, pre-payment x are recorded in the IC-card simultaneously; Because the expense of deduction is greater than the riding fee usefulness of reality, steward's active this moment prompt passengers is got off and must initiatively be removed the station small change; For example when the passenger gets off small change at the 14th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code mates, whether there is not small change, mate at train number, check code coupling and do not have also that (the judgement order here can be adjusted under the situation of small change, also can judge simultaneously), according to pre-payment x=2.9, expense 1.0, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=2.9-min{max[(2.9-1.0), 1.0], 1.8}=2.9-min{1.9,1.8}=1.1, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
For example, when the passenger when get on the bus in the 20th station, check code is B, pre-payment x=max (cost information at the 20th station, a+d)=max (2.3,2.0)=2.3; When getting off at the 24th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code B mates, whether there is not small change, mate at train number, check code mates and does not also have under the situation of small change, according to pre-payment x=2.3, expense 1.8, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=2.3-min{max[(2.3-1.8), 1.0], 1.8}=2.3-min{1.0,1.8}=1.3, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false, then small change failure.
For example, when the passenger when get on the bus in the 8th station, check code is A, pre-payment x=max (cost information at the 8th station, a+d)=max (1.8,2.0)=2.0; When getting off at the 9th station, at first, station small change IC-card read write line reads first riding information in the IC-card, and judge according to data information stored in self storage unit whether train number 725 mates, whether check code A mates, whether there is not small change, mate at train number, check code mates and does not also have under the situation of small change, according to pre-payment x=2.0, expense 1.8, starting fare a=1.0, ceiling price b=1.8, obtain this time actual should small change y, the y=x-min{max[(x-expense), a], b}=2.0-min{max[(2.0-1.8), 1.0], 1.8}=2.0-min{1.0,1.8}=1.0, simultaneously, IC-card is done " small change " mark; If above-mentioned condition is false (in other cases promptly), then small change failure.
Ground similar to Example 7 in first riding information that IC-card transmits, can replace prepayment information with starting point station number information, and by y=max (x, a+d)-min{max[(x-expense y), a], b} calculates the small change expense.At this, the starting point expense is by obtaining from the cost information table of storage.
In addition, the technical scheme among the embodiment 1-5 also can certainly, in the present invention, can only be considered starting fare according to actual conditions, or only consider ceiling price in conjunction with the related content of starting fare, ceiling price.
Embodiment 9
Usually, starting fare a should still, comprise a kind of special situation less than ceiling price b in embodiment 6,7,8, when starting fare a equates with ceiling price b (for example a=b=1.0), has just become the situation of the public transport of flat fare.
In addition, the situation of handling common all-purpose card card (abbreviation generic card) has only been described in embodiment 1-8, and generic card is come pre-payment by the meter volume, but, in the situation of reality, consider the interests of looking after city low-income groups, also need various monthly ticket cards (or be called " metering IC-card "), the metering IC-card with the difference of meter volume IC-card is: the former charges by deducting the number of times of riding, and the latter waits according to concrete mileage by bus to charge.To hold the metering IC-card the same with the passenger of meter volume IC-card in order to make, and can consume in the system among the embodiment 1-8, can be by following scheme realization.
At this, the major part in the present embodiment is identical with embodiment 1-8 or similar, only describes the difference with them here.
For example, here the card application type is divided into metering IC-card and meter volume IC-card (can certainly distinguish in more detail) according to the characteristics of customer group, in order to make the pre-payment module among the embodiment 1-8 handle meter volume IC-card and metering IC-card compatiblely, the pre-payment module can comprise meter volume submodule and the metering submodule that is used to deduct pre-payment.Similarly, the small change module can comprise meter volume submodule and the metering submodule that is used for small change.
When getting on the bus, if run into meter volume IC-card, the prepayment IC-card read write line is then deducted pre-payment (amount of money) by meter volume submodule from IC-card, and stores first riding information in IC-card; If run into the metering IC-card, the prepayment IC-card read write line is then deducted pre-payment (number of times) by the metering submodule from IC-card, for example can unify be: the deduction 2 times of getting on the bus when swiping the card pre-payment, the small change 1 time of getting off when swiping the card writes first riding information in the IC-card simultaneously;
When getting off, if run into meter volume IC-card, the small change IC-card read write line assigned address from the storage unit of IC-card earlier reads first riding information, and passes through meter volume submodule to the IC-card small change, then the riding information of storage origin-to-destination in the storage unit of small change IC-card read write line; If run into the metering IC-card, small change IC-card read write line earlier reads first riding information from the IC-card storage unit, and by the metering submodule to IC-card small change (number of times).This metering submodule for example if according to train number and pre-payment (first riding information) judge whether train number mates, whether the metering IC-card do not have small change, if train number mates and also do not have small change then to metering IC-card small change.
In addition, preferably, because the EEPROM that MIFARE 1 card adopts comprises 16 sectors, each sector is 4, every 16 bytes, take the piece as access unit, and each sector has independently one group of password and access control, so can realize the different data of different assigned address read-writes from an IC, for example for a monthly ticket IC-card, both can the Stored Value district of metering be read and write, in metering district insufficient in amount, can read and write the data in meter volume Stored Value district by microprocessor.But, on the whole, just count two kinds of situations of volume and metering,, then make the volume module of using tricks, then use the metering module for the metering card for meter volume card.Certainly, as previously mentioned, the IC-card sheet may have meter volume Stored Value district again in existing metering Stored Value district, so just can set: be only to read and write metering Stored Value district, or only read and write meter volume Stored Value district according to different needs, or the Stored Value of read-write metering earlier district, when the metering Stored Value district amount of money is not enough, just read and write meter volume Stored Value district or the like.
The difference of the present invention and prior art has more than been described, pass through present embodiment, can realize that sectional fare car, flat fare car adopt identical pre-payment module and small change module, and also can choose employing identical pre-payment module and small change module with the metering IC-card for meter volume IC-card.In addition, present embodiment is the preferred version among the 1-8 in conjunction with the embodiments, and for example vehicle-mounted prepayment IC-card read write line can be provided with a plurality of car doors place onboard or the like.
