Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system that enables wireless communication between an IC card having a function such as a commuter pass and a stored fair (SF) card and an automatic ticket gate.
[0002]
[Prior art]
In recent years, automatic ticket gates using magnetic tickets have been installed at the ticket gates of each station in the Tokyo metropolitan area, contributing to smooth ticket and ticket collection operations. Currently installed automatic ticket gates insert a ticket and mechanically transport it, read and write data during the transport period, and display guidance on the automatic ticket gate, but pass permission determination It may take a certain amount of time and may not be able to respond quickly when there are many passengers. Moreover, since the ticket is mechanically transported, troubles in the transport system are likely to occur. As a countermeasure against this, the present applicant has already proposed a system that enables communication between an IC card and an automatic ticket gate and automatically performs a contactless ticket gate (Japanese Patent Application No. 9-100172).
[0003]
[Problems to be solved by the invention]
By the way, the proposed automatic ticket gate system using the IC card has an advantage that the IC card has a memory function and an arithmetic function and the contents can be rewritten and can be used repeatedly. Utilizing these functions will enable further diversification of services to passengers. However, at present, sufficient measures are not always taken. Also, in the unlikely event that the contents of an IC card are tampered with or a counterfeit is used, there is a risk of causing serious damage, so it is required to take countermeasures.
[0004]
The present invention is to solve the above-mentioned problems. In an automatic ticket gate system using an IC card, the function of the IC card can be fully utilized to provide further services to passengers and improve security. The purpose is to plan.
[0005]
[Means for Solving the Problems]
The present invention is an automatic ticket gate system that enables wireless communication between an IC card having a ticket function and an automatic ticket gate for performing ticket gate processing, wherein the IC card has a deposit storage area for each company line. Subtract the boarding fee calculated by the automatic ticket gate from the deposit amount in the corresponding deposit storage area, and when the remaining amount in the deposit storage area is insufficient, the shortage amount from the remaining amount in the deposit storage area of other company lines It is characterized by the fact that it is compensated and processed.
In addition, the present invention compensates by distributing the shortage amount to the multiple company lines when the remaining amount does not satisfy the shortage amount for each of the other company lines and the total amount of the remaining amount of the other multiple company lines exceeds the shortage amount. It is characterized by a settlement process.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
1 is a conceptual diagram of the system of the present invention, FIG. 2 is a diagram for explaining the main configuration of an automatic ticket gate, FIG. 3 is a diagram for explaining the contents of an IC card memory, and FIG. 4 is a diagram for explaining points in the present invention. It is.
In FIG. 1, an automatic ticket gate 1 is provided with an antenna and a reader / writer at a predetermined position (not shown). When the IC card 2 provided with an antenna coil (not shown) is held at a predetermined position, the automatic ticket gate 1 By wireless coupling between the antenna and the coil of the IC card, the data of the IC card can be read without contact, or the data can be written to the IC card and the collected bill can be contacted without contact. Of course, it is possible to collect tickets using magnetic tickets.
[0008]
As shown in FIG. 2, the automatic ticket gate 1 includes a control unit 11 that controls each part such as guidance display, opening and closing of a door, and conveyance of a magnetic ticket, a fee calculation means 12 that performs fee calculation and settlement processing, a boarding distance A calculating means 13, a means 14 for calculating points for giving a predetermined benefit to the user according to the boarding distance, and a determining means 15 for determining whether or not the IC card is authentic are provided.
[0009]
As shown in FIG. 3, the IC card 2 has an ID code, has a stored fair (SF) area and a commuter pass area, and functions as an SF boarding pass and commuter pass. Furthermore, in the present invention, the boarding history is stored, and points are calculated based on this history.
[0010]
As shown in FIG. 4, for example, one point is added every 50 km, and when 100 points are reached, the purchase price of a ticket or commuter pass is discounted, or a free invitation ticket for a specific event is given. It is intended to give the user a predetermined benefit according to the boarding distance, and the relationship between the boarding distance and the points may be changed as appropriate, and not only the boarding distance but also the designated ticket, green Tickets may also be added. In the above description, the point calculation is performed on the automatic ticket gate side. However, since the IC card also has a calculation function, it may be obtained on the IC card side. Can reduce the processing load.
[0011]
A method of giving points will be described with reference to the processing flow of FIG.
Points are awarded during entry ticket processing in an automatic ticket gate. When the IC card is held over the automatic ticket checker, the automatic ticket checker reads data from the IC card, calculates the necessary fee, and performs a settlement process (steps 1 and 2). At this time, the distance corresponding to the fee is obtained, added to the boarding distance of the read IC card, and points are calculated from the integrated boarding distance (steps 3 and 4). Next, the points up to the previous time are updated with the calculated points, and the result is written in the IC card (steps 5 and 6). In addition, as a point calculation method, you may make it add a point for every boarding distance which a point increases, without calculating | requiring integrated boarding distance.
[0012]
Next, an example in which a single IC card can be boarded on a plurality of lines and can be settled will be described.
FIG. 6 is a diagram showing the SF area of an IC card, and there are areas for Company A, Company B, Company C, and Company D. Each company deposits a desired amount in advance by using a deposit machine. It can be done. When performing automatic ticket gates on each company line using this IC card, as shown in FIG. 7, the company line ID is set in the automatic ticket gate, and the company line ID of the automatic ticket gate is set on the IC card side. The recognizing means 21 recognizes the company line ID, and performs a settlement process using the deposit in the SF area of the predetermined company line. By the way, for example, when boarding the Company A line and trying to pass the automatic ticket gate, there may be a case where the amount of SF area of the Company A line is insufficient and the Company B line has a margin. At this time, it is inconvenient if the automatic ticket gate cannot be passed. Therefore, in the present invention, the inter-company settlement means 22 is provided in the IC card 2 to settle the shortage amount from the SF area of the B company line. In this case, since the settlement is only on numbers, the shortage amount for the A company line is separately received from the B company line by intercompany settlement.
[0013]
This intercompany settlement process will be described with reference to the process flow of FIG.
Assuming that the ticket gate is now on board the Company A line, it is first determined whether the remaining deposit amount in the SF area of the Company A line is insufficient for the fare (step 11). A settlement process is performed (step 20). If it is insufficient, a shortage amount α is calculated (step 12). Next, it is checked whether the remaining amount of the B to D company lines is greater than or equal to α, and if the B company line has room, it is set as (B−α) (subtract α from the SF area of the B company line), and C (C-α) if the company line has room, (D-α) if the company D line has room (steps 13 to 18), and (A + α) at the same time (SF area of the company A line) (Step 19) is settled (step 20). In this way, even if the deposit amount in the SF area of the Company A line is insufficient, if there is a surplus in the deposit amount in the SF area of the other company's line, it can be used for the settlement process.
[0014]
In the above explanation, the case where the shortage can be covered by another company line has been explained, but the remaining amount of each other company line is less than the shortage amount, but the total amount of the balance of multiple company lines exceeds the shortage amount Can also be settled. In this case, it is sufficient to apportion the shortage amount to multiple company lines as appropriate. As a method of apportionment, the entire remaining amount is allocated sequentially from the company line with the largest remaining amount, and the last fraction is the smallest remaining amount. A method such as assigning to a company line may be taken.
[0015]
An example of the intercompany settlement method is described below.
When (B-α) is calculated in step 16 of FIG. 8, the reduced amount α is stored as a data structure as shown in FIG. That is, in the ticket gate machine, information is collected based on the amount information (α) transferred between the companies, the information of the company (B company in the example of FIG. 8) and the company used (company A in the example of FIG. 8). . If you do this, it will be recorded how much money other companies used from the deposit of one company, so this information is raised to the upper ticket gate management system and the settlement process between each company is carried out If this is the case, it is possible to easily and strictly perform settlement between companies. As a result, “payment” and use of the IC card can be freely performed.
[0016]
Next, security measures in an automatic ticket gate system using an IC card will be described with reference to FIGS.
As shown in FIG. 10, each of the automatic ticket gates 1 ₁ , 1 ₂ ... 1 _n is connected to the host computer 3, and for example, when the power is turned on first in the morning, a security code (SC) is distributed. It has become. This security code is collectively managed on the host computer side.
[0017]
As shown in FIG. 2, the automatic ticket checker has a determination means, and performs a predetermined calculation from the distributed security code and the read ID code of the IC card, and the IC card is authentic. It is determined whether or not.
[0018]
Next, a process for determining whether or not the IC card is authentic by the determining means will be described with reference to FIG.
The automatic ticket checker reads the ID code from the IC card and performs predetermined calculation processing using the security code distributed from the host computer (steps 21 and 22). Next, it is determined whether or not the ID code is correct (step 23). Here, for convenience of explanation, a simple method will be described. For example, SC0, SC1,..., SCn, f are predetermined function forms, and k is an integer.
SC0 = f (ID) mod (k)
SC1 = f (ID) mod (k + 1)
……………
SCn = f (ID) mod (k + n)
Distribute a security code that satisfies Whether the ID code is correct, that is, whether or not the IC card is authentic is determined by whether or not the above formula is satisfied (step 23), and if it is correct, automatic ticket gate processing is performed (step 24). Since the ID code with a different system is used, it is determined that the IC card is not a genuine IC card, and the automatic ticket gate processing is stopped (step 25).
[0019]
The determination of whether or not the IC card is authentic is not limited to the above method, and an appropriate method such as a method using a random number, a public key method, a secret key method, or the like may be adopted. Further, if the security code distributed from the host computer is changed at predetermined intervals, the security can be further improved. Although the security code distributed to the automatic ticket checker is collectively managed by the host computer, it may be considered that there is no possibility of falsification in the automatic ticket checker after being distributed. However, it cannot be said that there is no possibility of such tampering. In that case, the host computer reads and checks at a predetermined interval, and if it has changed, a different security code is immediately distributed. What should I do?
[0020]
【The invention's effect】
As described above, according to the present invention, the accumulated distance can be accumulated by the memory function of the IC card. Therefore, a point system that gives profits to the user can be adopted, and the service can be further improved. be able to.
Further, a plurality of company lines can be used with one IC card, and in this case, settlement between companies can be easily and strictly performed. In this case, the user's merit can be understood as the total amount of the remaining amount, and any company can freely get in and out of any company, making it easy for users to enter an aging society. A railway system can be provided. In addition, there is no hassle to buy cash tickets at the station, and at the same time, there is less cash coming in and out of the station, making the station service a simple operation system and allowing you to use the railway at a low price. Become.
[0021]
In addition, a security code that is collectively managed by the host computer is distributed to each automatic ticket checker and the IC card ID code is used to determine whether or not the IC card is authentic. Can be prevented. Further, it is possible to further improve the security by changing the security code to be distributed at a predetermined interval or reading and checking the distributed security code every predetermined time.
[0022]
In addition, as shown in FIG. 10, when a fraudulent card is detected, the host computer is automatically notified so that a user can be specified and noted. By registering it in the computer and notifying each ticket gate of the ID code of this card, the automatic ticket gate stops when the lost card is automatically detected and can confirm the user.
