Abstract

PURPOSE:To avoid the usage of a medium with the expired term of validity and to keep a smooth passage state by permitting a user to recognize that the terms of validity of his own medium is drawing near. CONSTITUTION:Data for judging passage propriety transmitted from the antenna 24a for transmitting of a commutation ticket 21 is received by a gate 1 and the control part 4 of the gate 1 compares term of validity data added in data for judging passage propriety with present date and time. When the difference between the both becomes under a specified value, it is displayed that the terms of validity is drawing near in a display 3. Together with this, warning data indicating that the terms of validity is drawing near is transmitted to the commutation ticket 21. The commutation ticket 21 receives this and a speaker 31 gives warning.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contactless pass gate system that wirelessly transmits and receives data for determining passability between a medium such as a commuter pass and a gate such as an automatic ticket gate.

0002

[Prior Art] Passgate systems, which are applied to ticket gate processing in stations and entry/exit management in companies, transmit and receive data wirelessly between media such as commuter passes and gates such as automatic ticket gates. A contactless passgate system has been proposed. In this contactless passgate system, a medium possessed by the user must be equipped with a data transmission/reception function, and it is considered that an IC card is used as a component of such a medium. By wirelessly transmitting and receiving data between the medium and the gate in this manner, it is possible to simplify the handling of the medium when the user passes through the gate.

0003

SUMMARY OF THE INVENTION An object of the present invention is to enable a medium and/or a gate to warn that the expiration date of the medium is approaching, and to alert users to the approaching expiration date of the media they own. To provide a non-contact pass gate system that can recognize and prevent expired media from being displayed at the gate, thereby maintaining smooth traffic conditions.

0004

[Means for Solving the Problems] A contactless passgate system of the present invention wirelessly transmits and receives data including an expiration date of the medium between a medium and a gate. The present invention is characterized in that it is provided with a comparison means for comparing the expiration date of the medium with the current date and time, and a warning means for issuing a warning when the comparison result of the comparison means is less than a predetermined value.

[0005]

In the present invention, the expiration date of the medium and the current date and time are compared by the comparison means, and when the comparison result is less than a predetermined value, the warning means issues a warning. Therefore, as the expiration date approaches and the difference between the current date and time decreases,
The user can be informed of this by the occurrence of the warning.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view of an automatic ticket gate to which a contactless pass gate system according to an embodiment of the present invention is applied. The automatic ticket gate 1 is installed at the ticket gate in the station, and the side 1
Configure the ticket gate passageway in b. An antenna 2 for wireless transmission and reception, a display 3, and a speaker 12 are provided on the top surface of the automatic ticket gate 1. The antenna 2 forms a communicable area within a predetermined range above it, and transmits data for determining passability between the commuter pass and prepaid card presented within the communicable area by users passing through the ticket gate. Send and receive. In addition, the display 3 displays data for determining passability read from a medium such as a commuter pass presented by the user. Furthermore, a sensor (not shown) is provided on the side surface 1b, and this sensor detects the state of passage of users in the ticket gate passageway. In addition, the automatic ticket gate 1 is equipped with a door (not shown) that can be freely opened and closed, and if it is determined that the passage is not possible, the door is closed to block the ticket gate passage. The speaker 12 is driven when issuing a warning in a process to be described later. The speaker 12 can be replaced with a warning light composed of an LED or the like, and can be omitted when the display 3 displays a warning.

FIG. 2 is a block diagram showing the configuration of an automatic ticket gate and a commuter pass that constitute the above-mentioned contactless pass gate system. The control unit 4 of the automatic ticket gate 1 includes a demodulation circuit 6,
A data creation section 7 and a display controller 10 are connected. The demodulation circuit 6 inputs the data received by the reception antenna 2a to the control unit 4. On the other hand, the control unit 4 outputs transmission data to the data creation unit 7 and
inputs this transmission data to the modulation circuit 8. A high frequency signal of a predetermined frequency is inputted to the modulation circuit 8 from the oscillation circuit 9, and the modulation circuit 8 modulates this high frequency signal with transmission data, and then transmits it from the transmission antenna 2b. Further, the control unit 4 outputs display data to the display controller 10, and the display controller 10 drives the display 3 according to this display data. The control section 4 includes a storage section 5 , and data input/output to/from the control section 4 is stored in a predetermined memory area of the storage section 5 . In addition, when the speaker 12 or the warning light is provided, these are connected to the control unit 4 via a drive circuit, and drive data is outputted from the control unit 4 to the drive circuit at a predetermined timing. Further, each electronic circuit included in the automatic ticket gate 1 is supplied with power from a power supply circuit 11 .

I constituting the commuter pass which is the medium of this invention
A demodulation circuit 25 , a data creation section 28 , and a speaker driver 30 are connected to the control section 22 of the C card 21 .

The demodulation circuit 25 inputs the data received by the reception antenna 24b to the control section 22. This control section 22
outputs transmission data to the data creation section 28. The data creation section 28 inputs this transmission data to the modulation circuit 26. A high frequency signal of a predetermined frequency is inputted to the modulation circuit 26 from an oscillation circuit 27 . The modulation circuit 26 modulates this high frequency signal with transmission data and transmits it from the transmission antenna 24a.

The control unit 22 for the speaker driver 30
Drive data is output at predetermined timing in processing to be described later. The speaker driver 30 drives the speaker 31 based on this drive data. Data input and output to the control unit 22 is temporarily stored in the storage unit 23. The storage unit 23 also stores data for determining passability, such as the riding section, expiration date, gender of the user, start date and time of use, and user name. Electric power is supplied from a power supply circuit 29 to each electronic circuit constituting these IC cards 21 . The power supply circuit 29 may be supplied with power via a power carrier wave transmitted from the automatic ticket gate 1.

FIG. 3 is a flowchart showing the processing procedure of the automatic ticket gate and the IC card control section. When the IC card 21, which is a commuter pass, detects that it has been presented within the communicable area of the automatic ticket gate 1 by the user, it transmits recognition data including its own ID code (n21). A reading signal is transmitted from the automatic ticket gate 1 at regular time intervals, and the IC card 21 receives this reading signal and knows that the IC card 21 has entered the communicable area. In addition, IC card 21
If the IC card 21 is to be supplied with power by a power carrier wave transmitted from the automatic ticket gate 1, the processing procedure may be programmed so that the recognition data is transmitted after the IC card 21 is activated. When the automatic ticket gate 1 receives this recognition data, it transmits confirmation data to that effect (n1, n2), and the IC card 21 that received the confirmation data
transmits the passability determination data stored in the storage unit 23 (n22, n23).

[0012] The automatic ticket gate 1 receives data for determining passability transmitted from the IC card 21, and executes a passability determination based on this data. In this judgment process, the door is opened or closed depending on whether the data is appropriate (n
4-n5). After the determination of passability is completed, the control unit 4
reads the current date and time from a timer not shown, and subtracts the current date and time from the expiration date included in the passability determination data (n7). Next, this daily difference is set to a predetermined standard value k.
(n8), and if the daily difference is less than the reference value k, a warning is displayed using the display 3, a speaker, or a warning light, and warning data is transmitted to the IC card 21 (n9). This n8 corresponds to the comparison means of this invention, and n9 similarly corresponds to the warning means. The IC card 21 that has received this warning data drives the speaker 31 via the speaker driver 30 (n24, n25). The warning display in the automatic ticket gate 1 and the transmission of warning data are continuously executed while the user is inside the ticket gate passage (n
10→n4). Note that the control unit 4 of the automatic ticket gate 1 waits for transmission of recognition data from the next IC card 21 until an operation end command is input from the host device (n11→n
1).

As described above, according to this embodiment, I
The automatic ticket gate 1 detects that the IC card 21 is about to expire based on the expiry date data included in the passability determination data sent from the C card 21, and the automatic ticket gate 1 and the IC card 21 A warning will be displayed to make the user aware of this.

Note that a warning may be displayed on either the automatic ticket gate 1 or the IC card 21.

[0015]

According to the present invention, it is possible to warn the medium and/or the gate that the expiration date of the medium is approaching, so it is possible to prevent an expired medium from being presented at the gate, and to facilitate smooth passage. It has the advantage of being able to maintain its condition.
