BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contactless card type automatic ticket gate.

0002

[Prior Art] An automatic ticket gate sends out cyclic polling signals, and a passenger who is about to pass through the ticket gate approaches a designated communication area with an IC card (hereinafter simply referred to as a card) that has a communication function. When the ticket gate is opened, the automatic ticket gate sends the station name (station code) and date of the day, and the card that receives this determines the validity of the section and period, and sends the determination result to the automatic ticket gate. A contactless card-type automatic ticket gate has been proposed in which the automatic ticket gate controls passage through the ticket gate passage according to the determination result received by the automatic ticket gate.

0003

[Technical Problems to be Solved] One of the unresolved problems in such a contactless card type automatic ticket gate is the complete correspondence between card holders and persons whose passage through the ticket gate is restricted. In other words, in contactless card-type automatic ticket gates, unlike conventional card-type automatic ticket gates, the card is not inserted into the card slot and is simply passed through the communication area, so there is no need to enter the ticket gate passageway. If a passenger who enters first is blocked from passing through due to an error determination on the card or an empty ticket is detected and remains in the ticket gate aisle, if the subsequent passenger's card transmits a valid determination result, the passenger will be stopped in the ticket gate aisle. This results in the inconvenience that a passenger with an error determination or a person without a ticket is allowed to pass through, while a holder of a valid card is blocked from passing through.

[0004] In this way, the present invention allows the passenger for whom an error determination has been made or the person without a ticket to pass if the holder of a valid card succeeds the passenger or the person without a ticket for which an error determination has been made. The purpose of the present invention is to provide a contactless card-type automatic ticket gate device that can prevent such problems from occurring.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises an automatic ticket gate and an IC card, the automatic ticket gate is equipped with a passage control section and a communication control section, and the communication control section includes a passage control section and a communication control section. transmitting station name and date data from the card side, route determination and date determination based on the station name and date received on the card side, and transmitting the determination results to the communication control unit;
In the contactless card-type automatic ticket gate, the passage control unit allows or prohibits passage of a passenger through a ticket gate passageway according to a determination result inputted from the communication control unit. The present invention is characterized in that it is provided with a status monitoring means that constantly monitors whether or not the state is set and outputs a polling prohibition signal to the communication control section when the determination is prohibited.

[0006] Furthermore, if a polling prohibition signal is input to the communication control unit of an automatic ticket gate within a certain period of time after the communication control unit sends the data of the station name and the current day's date, a cancellation request signal is output. A request means is provided, and the card has the following information:
The present invention is characterized in that it includes a recovery means for returning to the state before the determination process when the cancellation request signal is received from the communication control unit.

[0007] If the card is capable of receiving a cancellation request signal during the validity determination, the cancellation request means outputs the cancellation request signal when the polling prohibition signal is input, and the card recovery means outputs the cancellation request signal during the validity determination. It is characterized in that the determination is canceled when a cancellation request signal is received.

[0008] Further, the cancellation requesting means may cancel the cancellation request from the card if a polling prohibition signal is input after the communication control unit of the automatic ticket gate sends out the data of the station name and the date of the day but before receiving the validity determination result from the card. The present invention is characterized in that a cancellation request signal is output upon reception of the validity determination result of the card, and the card restoration means rewrites the card to the state before the determination processing.

[0009]Furthermore, if the communication control unit of the automatic ticket gate does not receive the judgment result from the card within a certain period of time after transmitting the data of the station name and the date of the day, the cancellation requesting means cancels the request at the time when the certain period of time has elapsed. It is characterized by outputting a cancellation request signal.

0010

[Operation] The status monitoring means of the passage control section constantly monitors whether or not the automatic ticket gate is in the judgment prohibited state. The judgment prohibition state is when an error judgment result is received from the card and entry of a person into the ticket gate passageway is detected, or when entry of a non-tender is detected, and the next passenger's card is not valid. A state in which it is not possible to make a judgment. When the status monitoring means enters such a determination prohibited state, it outputs a polling prohibition signal to the communication control section. Therefore, the communication control unit does not send out polling. Therefore, there is no communication with the cards of subsequent passengers.

[0011] Furthermore, if a polling prohibition signal is input after transmitting the station name and current date data from the communication control unit of the automatic ticket gate (if a judgment prohibition state occurs),
The cancellation request means outputs a cancellation request signal. The communication control unit sends this to the card. If the card that receives this cancellation request signal is in the process of determining validity, it will stop the determination, and if the validity determination result has been sent, the card that has received this cancellation request signal will cancel the determination, and if the validity determination result has been sent, the card will cancel the validity determination (admission bit or Participation bit) is rewritten to the previous recorded content. That is,
Return to the state before the judgment process.

Embodiments Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of an automatic ticket gate G according to this embodiment. The illustrated example is of a bidirectional type. In other words, there are doors on the front and rear sides of the housing H to open and close the ticket gate passage so that passage can be restricted from the right to the left or from the left to the right in the drawing by switching a switch. 1a and 1b, and a display section 2 is provided on the front and rear sides of the housing to display possible passage directions to passengers. FIG. 1 shows a case where it is possible to pass from right to left. In addition, lamps 3 are provided at the top of the front and back sides to indicate whether or not the automatic ticket gate can be used. It lights red when the ticket gate cannot be used because ticket gate processing (allowing or blocking passage) for the preceding passenger has not been completed, or because a ticketless person has been detected, or because the automatic ticket gate is malfunctioning, and when it is available for use. lights up in blue.

Furthermore, a communication area 4 is provided at the front and rear upper portions of the housing for transmitting and receiving data by wireless communication with a card C held by a passenger. This communication area includes an antenna 4 connected to the communication control section described later.
A is facing me.

[0015] s is a human detector for detecting when a passenger enters, passes through, or exits the ticket passage formed between the adjacent automatic ticket gate, and is located on the side of the housing H and It is attached to arm 5. Speakers 6 are attached to both side surfaces of the housing H. This speaker is used when receiving an error judgment result from the card or when a non-tender is detected, to advise the passenger or non-tender to exit from the ticket gate passage. .

FIG. 2 shows the electrical configuration of the passage control section 7 and the card C. This automatic ticket gate has a passage control section 7 that controls passage regulation operations, and a communication control section 19. The passage control section 7 and the communication control section 19 are each configured using a microcomputer.

Central processing unit (CPU) 11 of passage control unit 7
performs arithmetic control processing using programs and data stored in the ROM 12 and data stored in the RAM 13. This CPU includes a door driver 15 that drives each door 1a, 1b via an I/O unit 14, a lamp driver 16 that controls lighting of the lamp 3, and a sensor driver 17 that receives a detection signal from the human detector s. , an audio driver 18 that drives the speaker 6, and a communication control section 19 that transmits and receives data to and from the card C are connected.

The CPU 11 of the passage control section 7 has status monitoring means in order to realize the functions necessary to achieve the object of the present invention. This status monitoring means constantly monitors whether or not this automatic ticket gate is in a judgment prohibited state. As mentioned above, the judgment prohibited state is when the ticket gate processing with the passenger has not been completed, when an error judgment result is received from the card via the communication control unit 19,
Or, in cases such as when a non-tender is detected, the validity of the next card is determined, and if the determination result is valid, the holder of that card has not actually passed through that ticket gate. However, there are cases where it would be unreasonable to perform judgment processing such as recording entry bits or exit bits.

The status monitoring means constantly monitors whether or not such a judgment prohibited state occurs, and outputs a logical value of 0 (L level) when it does not occur, and outputs a logical value of 1 when a judgment prohibited state occurs. (H level) is output to the communication control unit 19 as a polling prohibition signal. The communication control unit 19 is configured not to transmit polling while receiving the polling prohibition signal. Therefore, this automatic ticket gate does not communicate with the next card.

[0020] The storage unit (ROM) of the communication control unit 19 includes:
A system program necessary for communication with the card and data exchange with the passage control unit 7 and the station name (station code) of the station where this automatic ticket gate is installed are stored. Note that the communication method between the communication control unit 19 and the card C is not limited to the above-mentioned radio wave method, but may also employ an optical communication method, an electromagnetic coupling method, an electromagnetic induction method, or the like.

Furthermore, the CPU of the communication control section 19 has a cancellation request means in order to realize the unique functions of the present invention. This cancellation request means sends the passage control unit 7 of this automatic ticket gate within a predetermined time from the time when the communication control unit 19 sends the station code of the station where the automatic ticket gate is installed and the data of the current date to the communication area. It monitors whether a polling prohibition signal has been inputted or not, and outputs a cancellation request signal if a polling prohibition signal has been inputted. When this cancellation request signal is output, the communication control section 19 sends it out to the communication area.

Next, to explain the electrical configuration of the card C, this card, like a normal IC card, has an antenna 20 and a communication control section having the same function as the communication control section 19 of the automatic ticket gate G. 21, I/O unit 22, and CP
It has U23, memory 24 consisting of ROM and RAM, and power supply 25. Note that the power source 25 may not be provided inside the card C, but may receive power waves supplied from the communication control section 19 of the automatic ticket gate G to serve as a power source.

The ROM of the memory 24 stores reference data for determining the validity of the card, that is, data on sections and periods that define the valid range of the card. Further, in response to polling from the communication control unit 19 of the automatic ticket gate G, the CPU 23 transmits a response to the communication control unit 19 via the communication control unit 21, and further receives a response from the communication control unit 19. Based on the station code and today's date data, the validity of the card is determined using the reference data in the memory 24, and the communication control unit 21 is controlled to transmit the determination result.

Next, the operation of the automatic ticket gate will be explained with reference to a flowchart. FIG. 3 shows the CP of the passage control section 7.
It is a flow chart explaining operation of U. Program execution starts when the power is turned on, and first, the communication control unit 19
Check whether the judgment result has been input from (step 31
. Hereinafter, a step will be represented by S. ). When you enter
It is checked whether the content of the determination result is OK (S32). When the content of the determination result is valid, the passage control unit 7 returns to the first step and performs ticket inspection processing (
S33). This ticket inspection process is the same as the processing operation performed when a conventional automatic ticket inspection machine determines that a magnetic card is valid. That is, in the case of a normally open type, even if entry is detected, the door remains open until passage is detected, allowing passage. In addition, in the case of a normally closed type, if the door is opened to allow passage, and the validity judgment result for the next card is not received when passage is detected, a drive signal is output to the door driver and the door is closed. Go through the motions.

On the other hand, when the determination result from the communication control unit 19 is NG (error determination) (No in S32), the lamp 3 is turned on in red, and a polling prohibition signal is sent from the status monitoring means to the communication control unit 19. Output to. Further, the speaker 6 makes an announcement to the effect that the user should leave the passage. Then, it is determined whether or not the person has left based on the input of the human detector 3 (S35), and when it is determined that the person has left, the lamp 3 is turned on in blue, and then the polling prohibition signal is output from the status monitoring means. and cancels the judgment prohibition state (S36).

Further, if the judgment result is not received in step 31, a routine for checking the entry of a non-tender is executed, and the input status from the sensor driver 17 is checked to determine whether or not a non-tender has entered the ticket gate passage. (S37)
). Normally, if the passenger does not present the card, step 31 →
The operation is repeated along the flow from 37 to 31. When the entry of a non-bidding person is detected, the process proceeds to step 34, the lamp 3 is turned on in red, a judgment prohibition state is entered, and a polling prohibition signal is output. In this case as well, a recommendation to exit the ticket gate and an announcement to the effect that the card should be used to pass through are made. When exit is detected (S35 affirmative), the polling prohibition signal output is stopped (determination prohibition state is canceled) and the process returns to the first step.

FIG. 4 is a flowchart illustrating the operation of the CPU of the communication control section 19 of the automatic ticket gate G. When the communication control unit is started by turning on the power, it first checks the status of the automatic ticket gate (S41). That is, the status is OK depending on whether the input from the status monitoring means of the passage control section 7 is at L level or H level.
or NG. If the status is OK, polling is sent out (S42). If the status is NG, it is determined that a determination prohibition state has occurred, and the status check is repeated without sending polling. For example, if the status becomes NG because there is a person in the ticket gate passage at the time of startup, when that person exits the ticket gate passage, the status becomes OK and the judgment prohibition state is canceled, so polling is sent.

[0028] When a passenger approaches the ticket gate passageway and passes the card into the communication area while the blue lamp is on, the card transmits a response when it receives polling. Therefore, the communication control unit 19 waits for reception for, for example, 0.1 seconds from the time when the polling is sent (S43), and then checks whether or not a response has been received (S44). If the response is not received, a status check step is performed. Return to

When a response is received from the card, data including the station name and today's date is transmitted (S45), and the system waits for reception (S46). On the card side that passes through the communication area,
After sending the response, the CPU 23 stores the station name and date data received from the communication control unit 19 of the automatic ticket gate G in the RAM, and uses the station name data and the stored route data to determine the station name indicated by the route data. The validity of the route is determined by determining whether it is within the valid section, and the validity of the period is determined using date data and period data. Then, the determination result is transmitted from the communication control unit 21 of the card (C). When the communication control unit 19 receives the determination result from the card, it transfers it to the passage control unit 7 (S47).

As will be described later, before a card sends out a validity determination result, an entry bit or an exit bit is recorded on the card as a ticket gate process. In other words, the communication control unit 19 of the automatic ticket gate transmits data identifying whether the automatic ticket gate is for entry or exit, as well as the station name and the date of the day, so the card is sent based on the received identification data. If the determination result is valid, the entry bit or exit dot, which is the identification data received at that time, is recorded.

However, in the automatic ticket gate, it is possible that the judgment is prohibited immediately after transmitting the station name and current date data based on the response received from the card. In this case, the card holder cannot pass through the ticket gate even though the card is valid, so after the judgment prohibition status is lifted,
If an attempt is made to pass through the same ticket gate passage, since the entry bit or exit bit has already been recorded on that card, the judgment result will be NG and passage through that ticket gate passage will be blocked.

[0032] In the second embodiment of the present invention, in order to prevent such a malfunction when the judgment prohibition state occurs immediately after data transmission from the automatic ticket gate, the communication control unit 19 of the automatic ticket gate
A cancellation request means is provided for immediately transmitting a cancellation request signal to the card.

CPU of the communication control unit 19 in this embodiment
The operation will be explained using the flowchart of FIG. From the start of program execution, status check (S51), polling (S52), waiting for reception (S53), response reception (
The operations up to S54) and sending data after receiving the response (S55) are the same as the operations in S41 to S45 of the previous embodiment shown in FIG. In this embodiment, after data transmission, the timer of the cancellation request means is activated (S56), and it is then checked whether or not a determination result has been received from the card (S57).
. When the determination result is received, it is checked whether the content of the determination result is OK or NG (S58), and if it is OK, then the status at that time is checked (S59), and if it is OK, the passage control unit 7 The validity determination result is transferred to (S51
0). Also, when the determination result is NG, the determination result is output to the passage control section.

On the other hand, when the determination result is OK and the status is NG, that is, when the determination is prohibited, the cancellation request means is activated and outputs a cancellation request signal. Based on this, the communication control unit 19 transmits the cancellation request signal to the card (S511).
. In addition, in the step of waiting for reception of the determination result (S57), if the timer does not receive the result before the timeout (S57),
512 negative), it is checked whether the card has been repeatedly received, but if the timeout occurs without reception (S512 positive), the status at that time is checked (S513), and if OK, the card is outside the communication area. Judging that it is in
Returning to the first step (S51), the next polling is sent out. However, if the status is NG, the cancellation request means also operates in this case and sends a cancellation request signal to the card.

Next, the flow of the operation of the card's CPU will be explained based on FIG. 6.

It starts when the power is turned on, and first checks whether or not polling has been received (S61). When the polling is received, that is, when the card enters the communication area of the automatic ticket gate G, a response is sent (S62). ), then when the station name, date data, and entry/exit identification data are received from the automatic ticket gate (S63 affirmative), the section data, period data, and entry/exit bits registered in the card are used to identify the section and exit. Validity determination is made regarding the period and whether there is any overlap in entry or exit (S64). Next, while the determination is not completed (S6
5 (No), it is checked whether a cancellation request signal has been received from the communication control unit 19 (S66), and if it has not been received, the determination operation is continued, but if a cancellation request signal is received during the determination. If so, cancel the determination (S67).
, return to the first step (S61).

[0037] Also, when the determination is completed (S65 affirmative)
If the judgment result is NG, the first step (S
61), if the determination result is OK, the entry/exit record, that is, the entry bit or exit bit is recorded based on the identification data received from the communication control unit of the automatic ticket gate with which communication was made (S59). Further, the communication control unit of the card sends a validity determination signal, which is the determination result, to the communication control unit of the automatic ticket gate G (S610). Next, the card returns to the first step and waits for polling reception, but at the same time it also checks whether a cancellation is sent, and when a cancellation is received, the entry bit or exit bit recorded immediately before is changed to the state before the judgment process. (S612).

[0038] Therefore, if the automatic ticket gate G enters the judgment prohibition state immediately after the card is passed through the communication area and the validity determination result is transmitted, a cancellation request is sent from the automatic ticket gate G, and the cancellation request is sent. When the card receives the information, the card is returned to the state before the determination process, that is, the state before it was passed through the communication area. Of course, when the automatic ticket gate G, which is in the determination prohibited state, detects a person entering the ticket gate passage, it determines that the person does not have a ticket and prevents the person from passing through.

[0039]

Effects of the Invention As described above, according to the present invention, when a passenger who first enters the ticket gate is prevented from passing through due to an error determination of the card or due to detection of a non-bill card, a subsequent passenger may enter the ticket gate passage. Even if you pass the card through the communication area, the automatic ticket gate will output a judgment prohibition signal and subsequent polling will be prohibited, so there will be no ticket processing for the subsequent card, so if the ticket gate does not stop in the ticket gate passage. Passengers for whom an error determination has been made or those who do not have a ticket are prevented from being allowed to pass. Further, since the subsequent card is not subjected to determination processing, if the card is valid for the section and period, it can be passed through the communication area again.

[0040] Furthermore, if the automatic ticket gate becomes in a judgment prohibited state within a certain period of time from when the judgment data is sent, it immediately sends a cancellation request signal to the card, and when the card receives the cancellation request signal, , the judgment will be canceled, or after the judgment is completed, the state will be returned to the state before the judgment process, so even if a judgment prohibited state occurs immediately after the automatic ticket gate sends the judgment data to the card, the card will not be able to be used after that. It is possible to avoid a problem in which judgment processing is performed without permission and subsequent ticket gate processing becomes impossible.
