Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate management system suitable for use in managing entrance / exit of users at a ticket gate of a station, for example.

[0002]

2. Description of the Related Art FIG. 4 is a plan view showing a configuration of an example of a gate management system using a conventional magnetic card. As shown in FIG. 4, the gate 40 includes three gates 40a.
.About.40c are arranged in parallel. Further, in the figure, the F direction indicates the traveling direction of the user.

Information reading units 41a to 41c for reading information recorded in a magnetic recording unit (not shown) of a magnetic card used when a user enters and leaves each of the gates 40a to 40c are located on the right side of the entrances. It is provided in the vicinity. Further, each of the gates 40a to 40c is provided with an information writing section 42a to 42c for writing information in the magnetic recording section, respectively, near the right side of the exit, and further, in the vicinity of the exit of the gates 40a to 40c. Entry / exit permission / denial sections 43a to 43c for permitting entry / exit of persons are respectively provided.

As shown in FIG. 4, the effective length L of the gate 40 is
1 is set to a length of, for example, about 1.5 to 2 m. The user is required to set such a length at the gate 4
While passing 0 (while walking the effective length L1 of the gate 40), the information reading section 41 reads the information recorded in the magnetic recording section, and the control section reads the information.
Determine the validity of the information read by
This is for preparing information to be written in the magnetic recording unit.

The user reads information 41 in the gate 40.
After passing through, the information recorded in the magnetic recording section of the magnetic card of this user is read by the information reading section 41. The read information is a control unit (not shown)
And the validity (eg, expiration date) of the magnetic card is determined by this control unit. When the legitimacy of the magnetic card is confirmed, the information writing unit 42 writes information such as entry / exit record in the magnetic recording unit of the magnetic card of the user.

When the control unit determines that the information read by the information reading unit 41 is not valid (for example, when the expiration date of the magnetic card has already passed).
First, the control unit activates the entry / exit permission / denial unit 43. Figure 4
Is determined that the magnetic card of the user 51 is not valid, and the entry / exit permission / denial unit 43b shuts off the exit of the gate 40b,
It shows that the user 51 is prohibited from proceeding.

In contrast to the above-mentioned gate management system using a magnetic card, a gate management system using an IC card has been proposed. This system responds to the demand for smooth and high-speed gate management by eliminating congestion of users at gates where the majority of users go in and out, such as at ticket gates at stations. An integrated circuit (hereinafter referred to as IC
A module is called) and the card and the ticket gate exchange information without contact. in this way,
By using a non-contact method for exchanging information between the card and the ticket gate, it is possible to speed up the entry / exit management of the user's ticket gate.

FIG. 5 is a plan view showing the configuration of an example of the non-contact type gate management system described above. The same parts as those of the gate management system shown in FIG. 4 are designated by the same reference numerals, and duplicate description will be omitted as appropriate.

The gate management system shown in FIG. 5 is different from the gate management system shown in FIG. Information transfer units 55a to 55c are provided on the gates 40a to 40c, respectively. The information transfer unit 55 reads the information recorded in the IC module of the card, determines the read information, and the like,
It exchanges a series of information for writing predetermined information in the IC module.

When the user passes through the information transfer unit 55 of the gate 40, the information stored in the IC module of the user's card is read by the information transfer unit 55.
The read information is transmitted to a control unit (not shown) provided in the information transfer unit 55, and the control unit determines the validity of the card. When the authenticity of the card is confirmed by the control unit, the information transfer unit 55 writes information such as entry / exit records into the IC module of the user's card. The transfer of such information is performed in a short time (at substantially the same position) when the user passes through the information transfer unit.

When the control unit determines that the information read by the information transfer unit 55 is not valid (for example, when the expiration date of the card has already passed), the information transfer unit 55 sends and receives information. Gate 40
Block the exit and prohibit users from proceeding.

As described above, when the information is exchanged between the card and the ticket gate by the non-contact method, the reading and writing of the information can be performed at the same time in a short time. Therefore, the effective length L10 of the gate 40 is magnetic. It can be set shorter than that of using a card (effective length L1 shown in FIG. 4).

[0013]

However, the above-mentioned conventional gate management system has the following problems. First, in the gate management system using the magnetic card shown in FIG. 4, when the number of users entering and leaving the gate 40 increases, as shown in FIG. It will come into the L1 path. Therefore, when the user 51 is prohibited from proceeding as shown in FIG. 4, the users 52 and 53 following the user 51 are also prevented from proceeding.

In this way, if the progress of one user is prohibited, the progress of the user who has already entered the gate following this user is also hindered, so that smooth entrance / exit management of the gate can be performed. There was a problem that it could not be done. Therefore, there is a problem in that it is impossible to ensure high-speed gate access control.

In the gate management system using the IC card shown in FIG. 5, the effective length of the gate can be set shorter than that using the magnetic card. However, reading and writing of information in the IC module is possible. Since it is performed in a short time, there is a problem that a lot of information cannot be read and written.

Further, for example, when the information of the IC card is encrypted in order to improve the confidentiality of the IC card, it takes a long time to perform the encryption process. Therefore, the gate is effective to secure this processing time. There is a problem that the length cannot be set short and the advantage of using the IC card is lost.

Further, there is a problem that the structure of the information transfer unit 55 including the control unit for judging the read information becomes complicated and the information transfer unit 55 is burdened.

The present invention has been made to solve the above-mentioned problems, and in a gate management system using an IC card, it is possible to manage the entrance / exit management of a user's gate smoothly and at high speed. , It aims to provide a gate management system capable of reading and writing a lot of information.

[0019]

In order to achieve the above-mentioned object, a first solution of the gate management system according to the present invention is a gate management system for transmitting and receiving information in a contactless manner with a card having an information recording medium. A first gate (10) having a first information processing section (11) for reading information recorded on the information recording medium of the card; and a first gate (10) provided at a predetermined distance from the first gate, First
A second information processing section (2) for writing information corresponding to the information read by the gate of the card into the information recording medium of the card.
And a second gate (20) having 1).

The second solution of the gate management system is
The first information processing unit has a passage information writing unit that writes passage information indicating that the first gate has passed through to the information recording medium of the card, and the second information processing unit includes the passage information. It is characterized in that it has a passage information reading means for reading information.

The third solution of the gate management system is as follows.
A plurality of the first gates and the second gates are provided, and the first information processing unit of each of the first gates includes the second information processing of all of the second gates. It is characterized by exchanging information with the department.

The fourth solution of the gate management system is
The second gate includes an entrance / exit approval / disapproval unit (22) for controlling approval / disapproval of the entrance / exit of the user based on information read from the card of the user who has passed through the first gate. The path length (L3) between the entrance of the second gate and the entry / exit permission / denial section is formed to have a length occupied by one of the users.

[0023]

In the first solution of the above gate management system, the first information processing unit of the first gate reads the information on the card, and the second information processing unit of the second gate reads the information on the card. Is written. Therefore, since the information reading unit and the information writing unit are separately configured, the effective length from the entrance to the exit of the gate can be shortened, and a gate management system suitable for speeding up can be provided. Further, the first information processing unit and the second information processing unit
Since they are installed across a predetermined distance, it is possible to secure enough time to prepare the information to be written on the card, and it becomes possible to perform encryption processing of information and to store a lot of information. You can also write on the card.

In the second solving means of the gate management system, the passage information writing means writes the passage information indicating that the passage has passed the first gate, and the passage information reading means of the second gate passes the passage information. Information is read. Therefore, the second information processing unit can quickly search the information to be written on the card by reading the passage information, and can shorten the information search time. Further, when different cards are used at the first gate and the second gate, it is possible to easily discriminate them from the passage information, so that it is possible to suppress unauthorized use of the card.

In the third solving means, the first information processing unit of each first gate exchanges information with the second information processing units of all the second gates. Therefore, since the user who has passed through the first gate can pass through the arbitrary second gate, smoothing and speeding up / out of the gate can be achieved.

In the fourth solving means, when the user is prohibited from proceeding by the entrance / exit permission / prohibition section provided in the second gate, the subsequent user promptly moves to another second gate. You can move. Therefore, the entrance and exit of the gate can be facilitated.
