Abstract

PURPOSE:To obtain the noncontact automatic ticket examination system which performs processes on a card normally even when the transmission and reception of data are in a bad condition by checking the matching of discrimination data when the transmission and reception of the data are restarted after being interrupted. CONSTITUTION:When the card C is inserted into a communication area, a response signal including the discrimination data of the card C is sent out of the card C to an antenna (a). Then the card ID is stored in the RAM 13 of a main body. When the transmission and reception of the data are interrupted after a data writing completion signal is received from the card C, and then restarted, a door is opened without writing the data on the card on condition that the card ID stored in the RAM 13 matches a card ID received at the restart and the card writing completion signal to the card is received. Therefore, when the card C is used as a stored fare card, an initial ride fare is not subtracted double at the time of entrance and an adjusted fare is not subtracted double at the time of exiting either.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact type automatic ticket gate system, and more particularly to a contactless automatic ticket gate system which can effectively deal with data transfer failure.

[0002]

2. Description of the Related Art Currently, the automatic ticket gates that are widely used are automatic ticket gates by inserting a ticket or a commuter ticket into the main body of the automatic ticket gate (hereinafter, referred to as the main body of the contactless automatic ticket gate). Is configured to be performed. However, this insertion-type automatic ticket gate has a problem that the commuter ticket user has to insert and remove the commuter ticket from the commuter ticket compartment each time the commuter ticket user passes through the ticket gate.

Therefore, in order to solve such a problem, data is exchanged between the main body and the commuter pass (card) in a non-contact manner, and the automatic ticket gate is inserted without inserting the commuter pass into the main body. There has been proposed a non-contact type automatic ticket gate capable of carrying out the above (for example, Japanese Patent Laid-Open No. 1-246687).

[0004]

By the way, since the card according to the above proposal is an IC card having a communication function, it has a feature that its storage capacity is remarkably larger than that of a conventional magnetic card. By utilizing this feature, it is possible to have a function of stored fair (hereinafter referred to as SF) in addition to the commuter pass so that it can be used directly by the non-contact automatic ticket gate outside the commuter pass section. .

However, in the case where the card can be directly used in a non-contact type automatic ticket gate, the door is closed and the ticket gate passage is closed when a data transfer failure occurs (hereinafter sometimes referred to as NG). There is a risk that only the boarding fare will be deducted even though the passengers cannot pass.

In order to explain the cause of the above-mentioned inconvenience, data transfer between the main body and the card will be described with reference to the processing sequence of FIG. 3 used in the embodiment of the present invention.

Now, when the user is about to enter and the card enters the communication area of the main body, a polling response is sent from the card to the main body in response to a polling command from the main body, and data exchange is started. (Fig. 3
(1), (2)).

Next, a read command for reading the data contents of the card is sent from the main body to the card,
On the other hand, the commuter pass section data, SF data and the like stored in the card are sent from the card to the main body ((3) and (4) in FIG. 3).

In the main body, the data obtained from the card is used to perform an operation for the ticket gate processing, and the new data of the operation result, that is, the entrance data, is written to the card in order to write the new data to the card side. To send. Then, in the card, when new data is written, the fact is sent to the main body side ((5) and (6) in FIG. 3).

When the main body receives the fact that the card has written new data, the main body sends a close command to the card to end the data transfer, and the card sends the close command to the main body in response to the close command. A close response is sent to the destination ((7) and (8) in FIG. 3).

When the main body receives a close response from the card side, the door is opened (when the main body is a normally open type, the door is open) when the operation result permits the automatic ticket gate, and the remaining amount of the card is insufficient. In such a case, if the automatic ticket gate cannot be permitted, the door is controlled to be closed.

The above description is for the case where the data is normally exchanged between the main body and the card. For example, after writing new data to the card, the main body writes the write response. If the reception of the message ends abnormally (see the X mark in Fig. 3), the main body cannot perform the subsequent processing, that is, the main body is in the NG state, so the door is closed and the passage of the user's ticket gate is blocked. To be done.

In this case, since new data has already been written to the card, when the card is used as an SF card, the initial fare is reduced even though the card cannot pass through the automatic ticket gate passage. It is in the state of being

As described above, when data transfer ends abnormally on the way, the card is brought close to the communication area for re-communication, but in this case, the initial fare is reduced again. As a result, the double pulling problem occurs. Further, although the above-mentioned example shows the entrance, the inconvenience of double withdrawal of the payment will occur in the case of exit.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and its purpose is to ensure that the processing in the card is performed normally even when the data transfer between the main body and the card is not good. It is to provide a contactless automatic ticket gate system that can be operated.

[0016]

In order to achieve the above object, a non-contact type automatic ticket gate system according to the present invention is a non-contact type automatic ticket gate that transfers data without contact between a main body and a card. In the contact-type automatic ticket gate system, the card has a written storage means for storing the written data when the data writing to the card is completed, and the main body includes:
Storage means for storing identification data of the card, door closing control means for driving the door to close when the transfer of data between the main body and the card is interrupted, and transfer of the data is resumed When the identification data stored in the storage means and the identification data received at the time of restart thereof match and the data writing completion signal is received, the data writing process to the card is not performed. It has a door opening control means for driving the door to open.

[0017]

In the above structure, the door opening control means, when the data transfer is resumed after the data transfer is interrupted and the door is closed, the identification data stored in the storage means and the restart time On the condition that the received identification data matches, the door is opened without performing the data writing process on the card.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the main body G as seen from the ticket gate passage side, and has doors 1a and 1b for opening and closing the ticket gate passage on the front and rear side surfaces of the housing H, and the upper surface of the housing H. Is provided with a display unit 2 for displaying a predetermined guide to the user. Further, a communication area 3 for transmitting and receiving data to and from the card C carried by the user by wireless communication is provided on the upper part of the front of the housing H. An antenna a connected to a communication control unit described later faces this communication area 3.

S is a human detector for detecting a user's entry into the ticket gate passage, exit from the ticket gate passage, or passage, and is attached to the side surface of the housing H and the arm 4. A speaker 5 for broadcasting a predetermined guide to the user is attached to the side surface of the housing H.

Reference numeral 6 denotes a controller for controlling the operation of the main body G, the structure of which is shown in FIG. That is, the central processing unit (CPU) 11 of the controller 6 performs arithmetic control processing using the program data stored in the ROM 12 and the working data stored in the RAM 13.
This CPU is connected to each door 1 via the I / O unit 14.
a door driver 15 that drives a and 1b, a display driver 16 that controls the display content of the display unit 2, an amplifier 17 that amplifies the detection signal of the human detector S and takes it in, and an audio driver 18 that drives the speaker 5. , And a communication control unit 19 that transmits and receives data to and from the card C.

The communication controller 19 is a CPU different from the controller 6.
Like the well-known non-contact type automatic ticket gate, a predetermined interrogation signal is sent from the main body G to the card C through the antenna a, for example, a polling command signal sent at a fixed time interval. And card C
When the communication with is started, entry and participation data, that is,
It has the function of transmitting data such as station name and date of the day. The communication method between the main body G and the card C is
Not limited to the above-mentioned radio wave system, an optical communication system, an electromagnetic coupling system, an electromagnetic induction system, or the like can be adopted.

Next, the structure of the card C will be described. This card C is similar to a normal IC card having a communication function, an antenna 20, a communication control unit 21 having the same function as the communication control unit 19 of the main body G, and an I / O unit 2.
2, a CPU 23, a memory 24 including a ROM and a RAM, and a power supply 25. This memory 24 stores SF data in advance in addition to predetermined commuter pass data for a boarding section and the like, and is provided with a storage unit for storing the writing state of the data of the card C. Note that the power supply 25 may not be provided inside the card C, but may be configured to receive radio waves for power supply from the main body G and use it as a power supply.

The control operation of the automatic ticket gate system according to this embodiment will be described with reference to the processing sequence of FIG. Now, it is assumed that the main body G is in operation and the signal of the polling command is transmitted from the antenna a (FIG. 3 (1)). At this time, when the card C is inserted into the communication area 3, a response signal including identification data of the card C (hereinafter, referred to as a card ID) corresponding to the signal of the polling command,
The data is sent from the card C to the antenna a, and the card ID is stored in the RAM 13 of the main body G (FIG. 3 (2)). As a result, the main body G and the card C are brought into a communicable state.

Therefore, the main body G requests the card data for the card C (board section data, SF data, etc. stored in the memory 24 of the card C), and the card C responds to the request. Is sent to the main body G (FIGS. 3 (3) and 3 (4)).

The CPU 11 of the main body G performs arithmetic processing for entry and exit based on the card data obtained via the control unit 19, and the new arithmetic result is sent to the card C side. Then, in the card C, the new data is written in the memory 24, and the fact that the writing is normally performed is stored in a predetermined storage unit of the memory 24 (FIG. 3).
(5), (6)).

Of course, when the above-mentioned calculation result does not permit entry and exit, the door 1a is closed and
The display unit 2 displays that the entry and exit cannot be made due to expiration, overtaking, shortage of balance, etc., and the fact is broadcast via the speaker 5.

Now, in the case where the calculation result can permit entry and exit, that is, when the determination is OK, after the data writing to the card C is normally performed, the main body G is in an NG state for some reason. Then, the data transfer between the card C and the main body G cannot be performed thereafter. Therefore, transmission / reception indicating that the series of data processing is completed is not performed ((7) and (8) in FIG. 3). Therefore, since the main body G is in the same state as the failure, the door 1a
Operates to close the ticket gate.

When the main body G becomes NG, guidance for reapproaching the card C to the communication area 3 is given via the display section 2 and the speaker 5. Therefore, when the user brings the card C closer to the communication area 3 again, in response to the polling from the antenna a, the card C sends a polling response including the card ID to the main body G (FIG. 3).
(1 '), (2')). At this time, the data-written signal is also sent from the card C.

The CPU 11 of the main body G, on the condition that the card ID received this time and the card ID received before NG match, and the data writing process on the card C side is completed, From the main body G to the card C, data indicating that a series of data transfer is completed, that is, a close command is transmitted without taking in data from the device and writing new data to the card C, and corresponding to the data. When receiving the close response from the card C, the door 1a is opened.

Therefore, when the card C is used as an SF card, the initial fare will not be doubled when entering, and the settlement amount will not be doubled when entering.

In the above-described embodiment, the initial fare is reduced at the time of entry, but the reduction process may not be performed at the time of entry, but the payment may be made at the time of exit based on the entry station data.

[0032]

According to the non-contact type automatic ticket gate system of the present invention, the memory means for storing the card ID and the data transfer are interrupted after receiving the data written signal from the card,
When the data transfer is restarted again, the card ID stored in the storage means and the card I received at the restart
Since it has a door opening control means for opening the door without performing the data writing process to the card when D matches and the data writing signal to the card is received, When the card is used as an SF card, double-drawing can be prevented and automatic ticket gates can be performed.
