Abstract

PURPOSE:To prevent the illegal use of a commutation ticket by finding a illegal commu tation ticket such as the copied ones. CONSTITUTION:The device is provided with a collection section 18 discriminating 'suspicious' when commutation ticket information read at a ticket gate coincides with the ID number of any entrance commutation ticket information and when it is not matched with the ID number of any exit commutation ticket information by comparing entrance commutation ticket information with the exit commutation ticket information stored in a storage section 15. The collection section 18 obtains the differential time between the time required to read the matched entrance commutation ticket information and the time required to read new commutation ticket information as the degree of suspicion of the corresponding commutation ticket, and it stores the degree of suspicion in the storage device in the collection section 18 as well as the commutation ticket information. The time required to read the commutation ticket information stored in the storage section 15 is sent to a central collection center. The center acquires every information from the commutation ticket inspection machine of all stations, checking whether or not the same commutation ticket is used correctly in each station and discriminating the suspicious commutation ticket.

2. Description of the Related Art Conventionally, when ticketing a commuter pass at a station or the like, a ticket gate operator visually confirms the commuter pass or magnetically records information recorded on a magnetic material coated on the back side of the commuter pass. By reading it, the passenger boarding section of the commuter pass and the expiration date were confirmed. However, it is considered that the visual ticket gates impose a heavy burden on the ticket gates, and the certainty of the ticket may be deteriorated due to fatigue or the like. Also, with an automatic ticket gate that reads the information recorded on the magnetic material coated on the back side of the commuter pass, at the time of wicketing, the commuter pass is taken out of the passcase, for example, and then passed through the ticket gate to be put in the passcase again. Occurs. However, it is not preferable to carry the commuter pass as it is from the point of damage of the commuter pass.

In order to solve the above problems, the present inventor has disclosed, as Japanese Patent Laid-Open No. 01-219393, an image of a commuter ticket by illuminating the main surface of the commuter ticket on a transparent table with appropriate illumination. Is detected, the character strings of the boarding section and the expiration date are detected and recognized from the captured commuter ticket image, and if the recognized boarding section and the expiration date are not appropriate, the commuter ticket owner and station staff are informed of this fact. I proposed a commuter ticket gate device that does. This commuter ticket gate device has great advantages in terms of labor saving of ticket gates and convenience of users. However, because this commuter ticket gate device handles the image of the commuter ticket as it is,
There is a concern that fraud may occur due to copying of commuter passes. In particular, these concerns are increasing due to the recent spread of color copying, and countermeasures against them are strongly desired.

[0004]

As described above, in the conventional commuter ticket gate apparatus that automates the ticket inspection using the image of the commuter ticket, it is difficult to detect fraud due to color copying of the commuter ticket, etc. It was difficult to stop the act.

The present invention is intended to solve such a problem, and is a commuter pass ticketing apparatus which has a high credibility and can detect an illegal commuter pass such as a copy commuter pass to prevent an illegal boarding act. The purpose is to provide a commuter pass fraud check device.

[0006]

In order to achieve the above-mentioned object, the commuter ticket gate apparatus of the present invention captures an image of a commuter ticket, and from this commuter ticket image, the boarding section marked on the commuter ticket is valid. An entrance commuter ticket information storage that stores commuter ticket information read at the entrance ticket as entrance commuter ticket information together with a reading time in a commuter ticket inspection apparatus that reads commuter ticket information including a deadline and an ID number. Means, exit commuter ticket information storage means for storing commuter ticket information read at the exit ticket as exit commuter ticket information, commuter ticket information newly read at the entrance ticket and entrance commuter ticket stored in each of the storage means Means for comparing the information and the exit commuter pass information, and as a result of the comparison, the exit commuter ticket information that matches the entrance commuter ticket information newly read at the entrance ticket gate and which exit commuter ticket information If they do not match, a means for obtaining a difference time from the read time of the matched entrance commuter ticket information and the read time of the commuter ticket information newly read at the entrance ticket gate, and a commuter time when the difference time is newly read at the entrance ticket gate The suspiciousness of the ticket is stored together with the information of the commuter ticket.

In order to achieve the above-mentioned object, the commuter pass fraud check device of the present invention captures an image of the commuter pass and performs image analysis, and from this commuter pass image, the boarding section marked on the commuter pass, A means for reading commuter ticket information including an expiration date and an ID number, and commuter ticket information read at the entrance ticket gate is stored as entrance commuter ticket information together with the reading time and commuter ticket information read at the exit ticket ticket is read as exit commuter ticket information. Each station has commuter pass information storage means for storing together with time, and entrance commuter pass information, exit commuter pass information stored in the commuter pass information storage means, and means for transmitting these reading times to a central collection center. A plurality of commuter pass ticket inspection devices installed in, a means for receiving information transmitted from each commuter pass ticket inspection device, a means for accumulating the received information, and an accumulation device. Inlet commuter pass information, and includes a central counting center having means for determining suspicious commuter ticket on the basis of outlet commuter pass information and their reading time, a.

[0008]

In the commuter ticket gate apparatus of the present invention, the commuter ticket information read at the entrance ticket gate is stored in the entrance commuter ticket information storage means together with the reading time as entrance commuter ticket information. The commuter ticket information read at the exit ticket gate is stored in the exit commuter ticket information storage means as exit commuter ticket information. During this period, the commuter ticket information read at the entrance ticket gate is compared with the entrance commuter ticket information and exit commuter ticket information stored in each of the storage means. As a result of the comparison, when it is determined that the commuter ticket information read at the entrance ticket matches some entrance commuter ticket information and does not match any exit commuter ticket information, a new ticket is newly acquired at the entrance ticket from the matching reading time of the entrance commuter ticket information. The difference time from the read time of the read commuter pass information is calculated.
Then, this difference time is stored together with the information of the commuter ticket as the suspicious degree of the commuter ticket newly read at the entrance ticket gate.

Therefore, according to the present invention, an illegal commuter pass such as a copy commuter pass can be determined together with its suspiciousness, which can contribute to the prevention of an illegal boarding act. Further, in the commuter pass fraud check device of the present invention, the entrance commuter ticket information, the exit commuter ticket information and their reading times accumulated by the commuter ticket gates installed at each station are collected at the central collection center, and this central collection is carried out. The center judges suspicious commuter tickets based on this information.

Therefore, according to the present invention, a fraud that cannot be found by a fraud check in one station, for example, a fraud where a copy commuter pass is used to get on and off in a boarding section different from the original commuter pass. You can judge.

FIG. 3 is a block diagram showing the structure of the above-described central collection center 100 and the connection between the central collection center 100 and the commuter ticket gate apparatus shown in FIG.

As shown in the figure, the central collection center 10
0 is connected to a commuter ticket gate installed at each station through a dedicated data transmission path 200. The central counting center 100 receives the commuter ticket information and the reading time transmitted from each commuter ticket gate device, and the receiving unit 10 receives the commuter ticket information and the reading time.

04 and a control unit 105 that controls the above-described units.

Next, the operation of the commuter ticket gate apparatus of this embodiment will be described. As shown in FIG. 1, when the pressure sensor attached to the transparent plate 1 senses that the commuter pass P or the pass case P containing the commuter pass is placed on the transparent plate 1, the flash 2 lights up and the commuter pass is turned on. The main surface of the ticket P is illuminated. At this time, the information of the commuter pass image captured by the ITV camera 3 is A / D.
The conversion unit 5 converts the multi-valued digital image information into, for example, 0 to 255, and temporarily stores it in the multi-valued image memory 6.

Thereafter, the multi-valued digital image information stored in the multi-valued image memory 6 is binarized by the binarization unit 7 and stored in the binary image memory 8. Here, the binarization is performed by converting the character portion of the commuter pass image into a value of "1" and the other background portions into a value of "0". Specifically, for example, FIG.
As shown in, fixed threshold values are set in advance for multiple values (0 to 255), and "0" is set for parts below the threshold and "1" for parts exceeding the threshold. Binarization is performed by converting each. An example of the binarized commuter pass image is shown in FIG.

Next, the character string detecting unit 11 detects and cuts out a main character string from the binarized commuter pass image. As shown in FIG. 5, the character strings to be detected are the boarding section a, the expiration date b, and the ID number c.

Here, since the character string of the boarding section a composed of Kanji requires the process of integrating the separated components, the character string of the expiration date b which is composed of numbers without the separated components and has a large size is most suitable. Easy to detect. Therefore, first, the character string of the expiration date b is detected, and then the area in which the character string of the boarding section a and the character string of the ID number c exist is identified from the relative positional relationship with the character string of the expiration date b. To do. The details will be described below. First, labeling processing is performed on the binary image in FIG. In the labeling process, for example, as shown in FIG. 6, a binary image is divided into a plurality of connected areas 61, 62, 63 connected by a value of “1”, and each connected area 61,
It is performed by giving numbers (1, 2, 3) to 62 and 63.

Next, a rectangle circumscribing each connected region 61, 62, 63 is obtained, and the coordinates of each rectangle and the vertical and horizontal sizes are obtained as its shape data. here,
Since the size of the number indicating the expiration date is limited within a certain range, for example, from the detected rectangular areas, for example, the vertical / horizontal size is the closest to the number size indicating the expiration date of the month / day. 7 by selecting, as shown in FIG. 7, a rectangular area 71 of each number indicating the expiration date of the month / day,
72 and 73 are detected. After that, the detected rectangular areas 71, 72, 73 of the respective numbers are integrated into the area 81 of one character string as shown in FIG.

Further, as shown in FIG. 9, rectangular areas 91, 9 in which the year number of the expiration date exists from the relative positional relationship with the detected month / day character string area 81 of the expiration date.
2 is specified, and similar processing is performed for the rectangular areas 91 and 92. As a result, as shown in FIG. 10, all the character string areas 101 and 81 indicating the expiration date and the year / month / day are detected.

Next, character string areas 101 and 8 indicating the expiration date
11, the rectangular areas 111 to 123 in which the character elements indicating the boarding section and the ID number are present are detected from the relative positional relationship with 1. Here, the boarding section is composed of Chinese characters having a separated component. Therefore, as shown in FIG. 12, the distance in the arrangement direction between the rectangular regions is measured,
For rectangular areas that are less than a predetermined distance, by performing a process of unifying them, kanji such as "Kawa" and "Kichi" are put together.

After that, as shown in FIG. 13, the rectangular areas after integration are integrated as areas 131 and 132 of one character string for each boarding section and ID number.

The character string thus detected and cut out is sent to the character recognition unit 12. The character recognition unit 12 performs character recognition on each input character by, for example, matching with a dictionary pattern, and sends the result to the verification unit 13 as commuter pass information.

The verification unit 13 verifies from the acquired commuter pass information whether the boarding section is appropriate or whether the expiry date has not passed, and if both the boarding section and the expiry date are appropriate, it is shown in FIG. As described above, the end of the commuter pass P or the pass case P accommodating the commuter pass is attached to the movable lever 14 on the transparent plate 1.
Lift by 1. This makes it easier for the owner to take the commuter pass P or pass case P.

Further, when both the boarding section and the expiration date are proper, all the commuter pass information including the ID number is stored in the storage unit 15. At this time, the current time indicated by the timer-16 is accumulated in the accumulating unit 15 as the reading time together with the commuter pass information. However, the accumulation of the commuter pass information and the reading time in the accumulation unit 15 is unconditionally performed at the exit ticket gate, but is performed after the processing of the counting unit 19 described later at the entrance ticket gate.

When the boarding section or the expiration date is not appropriate, the verification unit 13 notifies the owner of the commuter pass P and the station staff by the notification device 14 by, for example, a warning message.

By the way, most of the commuter pass users are those who commute to work or attend school, and they repeatedly get on and off at the same station every day. Therefore, if the commuter pass confirmed at the entrance ticket gate in a certain station is subsequently confirmed at the entrance ticket gate without being confirmed at the exit ticket gate, it will not be in tune. Of course, it is not unthinkable to return by another means of transportation and pass through the entrance ticket gate for some reason, but it seems suspicious that the same thing will continue for several days.

Therefore, in the commuter pass ticket inspection apparatus of this embodiment, at the entrance ticket gate, the verification unit 13 determines that the boarding section and the validity period of the commuter pass are appropriate, and then the following commuter pass fraud checks are totaled. This is done in section 18.

FIG. 15 is a flow chart showing the procedure of this commuter pass fraud check.

At the entrance ticket gate, the read commuter pass information A is sent to the counting unit 18 before being stored in the storage unit 15. After obtaining the commuter pass information A (step 1
501), and the current time at that time is obtained as the reading time T1 of the commuter pass information A from the timer 16 (step 1502).

Next, the counting unit 18 reads out from the storage unit 15 as the commuter pass information that has already been stored as read at the entrance ticket gate, that is, the entrance commuter pass information B (step 1503), and further this entrance commuter pass information B. The reading time T2 stored in association with is read (step 15).
04).

After that, the counting unit 18 compares the commuter pass information A read at the entrance ticket gate with the entrance commuter pass information B read from the storage unit 15 (step 1505). As a result of this comparison, the ID number of a certain entrance commuter pass information B read from the storage unit 15 is I of the commuter pass information A read at the entrance ticket gate.
If it coincides with the D number, the counting unit 18 subsequently reads out the commuter pass information stored as the one already read at the exit ticket gate, that is, the exit commuter pass information C from the storage unit 15 (step 1506).

Next, the counting section 18 compares the exit commuter ticket information C with the commuter ticket information A read at the entrance ticket gate (step 1507). As a result, if the ID number of any exit commuter pass information C does not match the ID number of the commuter pass information A (step 1508), it is determined that the commuter pass read at the entrance ticket this time is suspicious, Step 150
The difference time between the read time T2 of the entrance commuter pass information B and the read time T1 of the commuter pass information A that match in 4 is obtained as the suspicious degree of the commuter pass (step 1509). Thereafter, the obtained suspiciousness degree is recorded in the storage device in the counting unit 18 together with the commuter pass information A (step 1510).

Further, as a result of the comparison in step 1505,
ID number of commuter pass information A is which ID of entrance commuter pass information B
If the number does not match (step 1511), the commuter pass information A is recorded in the storage unit 15 as the new entrance commuter pass information B together with the reading time T1 (step 151).
2). Further, when the comparison result in step 1507 shows that the ID number of the commuter pass information A matches the ID number of the exit commuter pass information C, the commuter pass information A is read as new entrance commuter pass information B as well. Storage unit 15 together with time T1
(Step 1512).

The contents of the storage unit 15 are reset in a predetermined time period, for example, every day from the end of the train operation work to the start of the first train operation.

As a result, it becomes possible to detect fraudulent use of the copy commuter pass by the commuter pass ticketing device in one station. For example, if a high suspiciousness degree is recorded for the same commuter pass for several days by looking at the record of the counting unit 18, it can be considered that the commuter pass has an extremely high credibility and is illegal. Note that the suspiciousness is higher as the value is smaller.

Furthermore, in the commuter pass ticket examination apparatus of this embodiment, before the contents of the accumulation unit 15 are reset, the transmission unit 17 transmits the accumulated contents to the central counting center 100.
When the central counting center 100 obtains the commuter ticket information and the reading time from the commuter ticket gates of all stations connected through the dedicated data transmission path 200, the commuter ticket of the following one cannot be found by the commuter ticket gate of one station. Check for unauthorized use of.

For example, as shown in FIG. 16, when the boarding section of a certain commuter pass is from station A to station E, the commuter pass user can get on and off at any station A to E. Therefore, it is possible that the original commuter pass holder gets from A station and gets off at E station, and the copy commuter pass holder gets from B station and gets off at D station.

FIG. 17 is a flow chart showing the procedure of the commuter pass fraud check carried out by the central totaling center 100.

When the reception of the commuter pass information and the reading time from all the stations is completed (steps 1701, 1702),
The central counting unit 103 in the central counting center 100 extracts commuter pass information and reading time for each commuter pass (step 1703). Then, it is checked whether or not the commuter pass has passed through the entrance ticket gate and the exit ticket gate in the correct order along the time flow indicated by each reading time (step 17).
04). That is, if the same commuter pass passes through the entrance ticket gate twice in succession, or if the same commuter pass passes through the exit ticket gate twice in succession, it is determined to be suspicious. When the suspicion is judged, the commuter pass information is recorded in the storage device in the central totaling unit 103 as a suspicious commuter pass candidate (step 1705). After that, when the fraudulent check is completed for all the commuter passes (step 170)
6), the operation of the central totalizing unit 103 ends.

After the above fraudulent check is executed for a predetermined period, the suspicious commuter pass candidates accumulated in the storage device in the central counting unit 103 are output through the output device 104. Then, from this output result, the number of times the same suspicious commuter pass candidate is recorded is checked to identify the fraudulent commuter pass.

If the wrong person is caught wrongly, it may become a serious human rights problem. Therefore, it is desirable that the above-mentioned fraudulent check be performed over a long period of time and finally be visually confirmed. Therefore, for a commuter pass determined to be suspicious after a certain period of time, when this is detected at the entrance ticket gate, multi-valued image information after A / D conversion is stored in the image storage unit 9, and the display unit This is displayed at 10 for visual confirmation.

As described above, according to the commuter ticket gate apparatus of the present embodiment, it is possible to detect an illegal commuter ticket such as a copy commuter ticket with extremely high credibility, and to prevent an illegal boarding act. It can be useful.

As another embodiment of the present invention, the boarding time and the alighting time are estimated from the time when the commuter ticket is read based on the timetable, and the "on" and "out" of the same commuter ticket are roughly estimated. May be used and the result may be used as supplementary information for the commuter pass fraud check. For example, in FIG.
In the case where the commuter pass holder who got on at A station at 9:00 and got off at E station at 9:30, got on from B station at 9:10 and got off at D station at 9:25, Obviously, the commuter pass can be identified as being illegally used.

When a suspicious commuter pass such as a copy commuter pass is detected at the ticket gate, the notification device 14 notifies only the staff member of the fact, and an image of the commuter pass user is recorded by, for example, a security camera. It is also possible.

Although a fixed threshold value is used in this embodiment as a binarization method, a binarization method using a floating threshold value which varies the threshold value depending on the situation is also conceivable.

Further, as the character string detecting method, the labeling process is used in the present embodiment, but a method using the projection information of the image may be considered.

In addition to the warning sound, a method using a warning light or voice rule synthesis can be considered as the notification method.

Further, as for the procedure of the irregularity check of the commuter pass carried out at the central totaling center, various methods other than this embodiment can be considered.

[0052]

As described above, according to the commuter pass ticket inspection apparatus of the present invention, the commuter pass confirmed at the entrance ticket gate within one station is confirmed again at the entrance ticket gate before being confirmed at the exit ticket gate. By determining the case as suspicious, it is possible to find an illegal commuter pass such as a copy commuter pass.

Further, according to the commuter pass fraud check device of the present invention, fraud that cannot be detected only by fraud check in one station, for example, a copy commuter pass is used for getting on and off in a boarding section different from the original commuter pass. It is possible to judge such fraud.
