Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic ticket gate apparatus installed at a railway station or the like.
[0002]
[Prior art]
FIG. 17 is a schematic side view showing an example of a conventional automatic ticket gate. The automatic ticket gate 100 includes a pair of upper and lower sensors 101a and 101b provided on the entrance side (right side in the figure), a pair of upper and lower sensors 102a and 102b provided in the center, and the exit side (left side in the figure). And a pair of upper and lower sensors 103a and 103b. These sensors are composed of optical sensors, and when the upper and lower sensors are simultaneously shielded from light, it is detected that a person has reached that position. Reference numeral 104 denotes an entrance-side gate door, and 105 denotes an exit-side gate door.
[0003]
When the automatic ticket gate 100 is a contact type automatic ticket gate using a magnetic card as a boarding medium, a passenger inserts a magnetic card into a ticket slot (not shown) of the automatic ticket gate 100 and passes there. When 100 is a non-contact type automatic ticket gate device using a non-contact IC card as a boarding medium, the passenger passes by holding the non-contact IC card over the antenna portion (not shown) of the automatic ticket gate device 100. In this case, first, the entrance side sensors 101 a and 101 b are simultaneously shielded from light, and it is detected that the passenger has entered the automatic ticket gate 100. When the passenger proceeds through the passage, the sensors 101a and 101b on the entrance side change from the light shielding state to the light transmitting state. When the passenger reaches the central portion, the sensors 102a and 102b in the central portion are simultaneously shielded from light, thereby detecting that the passenger has reached the central portion. Thereafter, when the passenger proceeds toward the exit, the sensors 102a and 102b in the central portion change from the light shielding state to the light transmitting state, and when the passenger reaches the exit, the sensors 103a and 103b on the exit side simultaneously enter the light shielding state. When the passenger exits from the exit, the exit-side sensors 103a and 103b change from the light-shielding state to the light-transmitting state, and the exit of the passenger is detected.
[0004]
On the other hand, a correct ticket counter is provided in the control unit in the automatic ticket gate 100. The initial value of the correct ticket counter is 0. If it is determined that the boarding medium thrown in (or held by) the passenger is a normal ticket, the value of the correct ticket counter is +1. A state where the correct ticket counter is +1 means that one passenger is allowed to pass. When the sensors 102a and 102b change from the light shielding state to the light transmitting state, that is, when it is detected that the passenger has passed through the central portion, the value of the correct bill counter is decremented by 1 and returned to 0. .
[0005]
As a prior art relating to passenger traffic management using such a genuine ticket counter, there is Patent Document 1 below. In the automatic ticket gate described in this document, the position of the upper outlet sensor among the upper and lower outlet sensors near the outlet is set lower than the position of the central upper sensor. When the passerby is an adult, the correct ticket counter is subtracted by simultaneously shielding light from the upper and lower sensors in the center. Further, when the passerby is a child, even if the upper and lower sensors in the center are not shielded simultaneously, the upper exit sensor detects the child and shields it, thereby subtracting the correct ticket counter.
[0006]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-143687 (paragraphs 0029, 0041 to 0043, FIGS. 1 and 8)
[0007]
[Problems to be solved by the invention]
In the automatic ticket gate 100 shown in FIG. 17, passenger traffic is detected by simultaneous shielding of a pair of upper and lower sensors. Therefore, when a child who does not shield the upper and lower sensors at the same time passes using a normal vehicle, The ticket counter is not subtracted, and the correct ticket counter remains. As a result, the passenger following the child can pass without a bill. In addition, not only children but also the upper and lower sensors may not be shielded simultaneously depending on the posture of the passenger. In this case as well, there is a problem in that the subsequent passengers are allowed to pass through without bills.
[0008]
On the other hand, in the above-mentioned Patent Document 1, when the child passes, even if the center upper sensor is not shielded from light and the correct bill counter is not subtracted, the exit sensor provided at a position lower than the upper sensor When a child reaches the exit for detection, the ticket counter is subtracted if the ticket is a child ticket, preventing the next customer from passing through without a bill due to the remaining ticket counter remaining. be able to.
[0009]
However, the automatic ticket gate apparatus of Patent Document 1 has the following problems. That is, if a child is detected by only one point of the upper exit sensor among the exit sensors, it is determined that the child has been detected even if the upper exit sensor is shielded from light by a passenger's baggage, etc. Due to detection, the correct ticket counter of the child ticket issuer may be unnecessarily subtracted. Since the upper exit sensor is provided at a height of 115 cm, there is a possibility that the correct ticket counter may be subtracted without detecting the child depending on the posture of the short child ticket inserter. On the other hand, if the child is detected by simultaneous shielding of the upper exit sensor and the lower exit sensor, the above-mentioned problem of false detection due to noise is reduced, but simultaneous shielding is not achieved depending on the posture of the child ticket holder. There is a possibility that the correct ticket counter will be decremented.
[0010]
Moreover, in the automatic ticket gate device of Patent Document 1, since the ticket counter is subtracted when the exit sensor detects the child, the adult without a bill who is the next customer reaches the center before the child reaches the exit. Then, this adult can pass without a bill. To explain this step by step, first, when the child, who is a guest, inserts a child ticket, the ticket counter is incremented by one. However, even if the child reaches the center, the upper and lower sensors in the center are not shielded simultaneously. The correct ticket counter is not subtracted, and the counter value remains at 1. And if the unpaid adult who is the next customer reaches the center before the child reaches the exit, the upper and lower sensors in the center are shielded simultaneously, and the correct ticket counter is normally subtracted from 1 to 0. This next customer is not judged as a billless customer and is treated as a normal customer. That is, since the automatic ticket gate device does not recognize that a no-card abnormality has occurred, it keeps the gate door open. When the child reaches the exit and is detected by the exit sensor, the ticket counter is already 0 and is not decremented, but the gate door remains open because no billless abnormality has occurred. Children can leave the exit. Similarly, when a subsequent adult is detected by the exit sensor, the correct ticket counter is not subtracted in the same manner, but since this adult is not determined to be a no-ticket customer, the gate door remains open and the adult follows the child. You can leave the exit. In this way, the adult following the child can pass without a bill.
[0011]
SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic ticket gate device that can eliminate the occurrence of the above-described problems, accurately perform traffic management, and reliably prevent illegal traffic without a bill.
[0012]
[Means for Solving the Problems]
In the present invention, in an automatic ticket gate device that controls the opening and closing of the gate door by determining the suitability of the boarding medium and permits or prohibits passage, the first detection means for detecting the position of the human and the adult / child are detected. A second detection means. The first detection means is composed of a plurality of sensors installed at a height that can detect a passerby of the minimum age who needs a child ticket, and these sensors are arranged in a row in the direction of travel. Further, the interval between adjacent sensors is set to an interval at which one person is detected simultaneously. A 2nd detection means distinguishes and detects an adult and a child based on a passer's height. Then, the position of the passer-by is tracked by the first detection means, and the passer-by is managed as an adult or a child based on the detection result of the second detection means.
[0013]
In this way, it is possible to accurately track and manage humans with the first detection means, and to detect adults / children based on the height of the passersby by the second detection means. Adult / pediatric management. As a result, erroneous traffic management is caused due to erroneous detection due to noise as in the case of detection with only one sensor (for example, when a genuine bill counter is used as in Patent Document 1, the counter is unnecessary) Will not subtract). Further, by separating the first detection means for position detection and the second detection means for adult / children detection, the detection timing by the first detection means, Even if a deviation occurs between the detection timing of the first detection means and the second detection means, once the adult is detected, the first detection means can track and manage the customer as an adult. For this reason, it is possible to accurately detect and track adults / children even if the conventional vertical sensor is in a traffic state where simultaneous light shielding is not established. There is no problem that a child is detected and missed by his / her posture. Further, by separating the first and second detection means and using the second detection means only for adult / child discrimination, the position of the second detection means in the passage direction is not restricted, The second detection means can be provided at an arbitrary position.
[0014]
The “row” as used in the present invention refers to a case where a plurality of sensors are alternately arranged in a staggered manner in addition to a case where a plurality of sensors are arranged in a straight line. It also includes the case where they are arranged in a shape. Moreover, the case where the height from the floor surface of some sensors among a plurality of sensors is shifted in the vertical direction is also included.
[0015]
In the present invention, the second detection means is provided near the entrance of the passage, the detection result of the second detection means is stored, and the second detection means is moved to a predetermined position closer to the center of the passage than the second detection means. When the first detection means detects that a passerby has arrived, the detection result of the second detection means is referred to and the passage process is performed based on the detection result. According to this, in addition to being able to cope with the unnatural posture of the passerby by separating the first and second detection means, the second detection means is provided near the entrance of the passage, so that an adult / child can be at an early stage. Can be confirmed. That is, when the passer-by arrives at the predetermined position, the adult / child discrimination has already been completed, so that it is possible to immediately perform pass-through processing such as no-card determination and gate door opening / closing at the predetermined position. As a result, for example, when traffic management is performed using a ticket counter, the ticket counter can be subtracted when the child who has inserted the child ticket reaches a predetermined position. When the no-bed adult reaches the center, there is no remaining ticket counter. At that time, the adult can be judged as a no-ticket customer, the gate door can be closed, and traffic can be prohibited. Therefore, unlike the patent document 1, since the previous customer cannot be determined as a child until reaching the exit, there is no problem that the next customer is allowed to pass without a bill.
[0016]
Further, in the present invention, it is determined whether or not there is a front customer within a certain distance in front of the passerby. If there is no front customer within a certain distance, the detection range by the second detection means is widened and within a certain distance. When there is a front customer, the detection range is switched so as to narrow the detection range by the second detection means. When the distance from the previous customer is far, there is a low possibility of erroneous detection of adults / children between the front and rear customers, but there is a feature that each person can easily take a free passage posture. Therefore, in this case, widening the detection range enables accurate detection regardless of the passer's posture. On the other hand, when the distance from the front customer is close, it is difficult for each person to take a free passage posture, but there is a high possibility that an adult / child may be erroneously detected between the front and rear customers. Therefore, in this case, by narrowing the detection range, there is no possibility of erroneous detection of adults / children before and after even when an adult and a child are consecutive. By switching the detection range in this way, optimal detection can be performed according to the situation.
[0017]
In the present invention, a management table is provided for managing the position information of the passers and the determination information of the boarding medium for each passerby. According to this, inconsistency does not occur in the number of passing people, and it becomes possible to perform traffic management without using the calculation by the correct bill counter.
[0018]

[0019]
The automatic ticket gate 50 as described above is installed in a station or the like, and when a passenger holds the non-contact IC card over the antenna 54, the data of the non-contact IC card read by the antenna 54 is provided inside the main body 51. The control unit determines whether the boarding medium is appropriate and controls the opening and closing of the gate doors 52 and 53, and permits or prohibits passage. Here, a contactless automatic ticket gate using a contactless IC card as a boarding medium is taken as an example, but the present invention is a contact type automatic ticket gate using a magnetic card, a magnetic card and a contactless IC. The present invention can also be applied to a hybrid automatic ticket gate that can use both cards.
[0020]
FIG. 2 is a side view showing a state in which the cover 59 of the side plate 57 of the automatic ticket gate 50 on the right side in FIG. 1 is removed. Reference numerals 1 to 16 are position sensors for tracking the human position arranged in a straight line in the direction of travel, and here are constituted by transmissive optical sensors. In addition, the side plate 57 in the automatic ticket gate 50 on the left side of FIG. 1 is also provided with a transmission type optical sensor at a position facing each of the position sensors 1 to 16 with the passage 61 interposed therebetween. In each automatic ticket checker 50, the light projecting elements and the light receiving elements constituting the sensor are alternately arranged in the passing direction, and the light projecting element of one automatic ticket checker 50 and the other automatic ticket checker 50 are arranged. 50 light receiving elements face each other across the passage 61. As a result, compared to the case where only the light projecting elements are arranged in one automatic ticket gate device 50 and only the light receiving elements are arranged in the other automatic ticket gate device 50, the interval between adjacent light projecting elements is doubled. Even if the number of sensors increases, it is possible to prevent light interference between sensors and avoid malfunction. L1 in FIGS. 3 and 4 indicates the optical axis of light projected from the light projecting element to the light receiving element. In FIG. 2, the interval y between the position sensors 1 to 16 is set to an interval smaller than the front-rear width of the human torso, for example, 8 cm. As a result, adjacent sensors (for example, sensor 8 and sensor 9) are simultaneously shielded by one person and output detection signals. The position sensors 1-16 mentioned above comprise an example of the 1st detection means of this invention. Of these position sensors, sensors 4, 5, and 6 and sensors 11, 12, and 13 are billless detection sensors. In this embodiment, the automatic ticket gate device 50 is a ticket gate dual-purpose machine that can be entered from both directions, and the sensors 4, 5, and 6 are sensorless detection sensors when a passenger enters from the right direction in FIG. Sensors 11, 12, and 13 are sensorless detection sensors when a passenger enters from the left in FIG. 2.
[0021]
The first detection means of the present invention is not limited to the position sensors 1 to 16 shown here, and for example, a reflection type optical sensor can be used as the detection means. Further, in FIG. 2, 16 position sensors 1 to 16 are arranged in a row, but this is an example, and the number of sensors may be appropriately selected according to the passage length of the automatic ticket gate device 50. In FIG. 2, the position sensors 1 to 16 are arranged in a straight line, but the heights of adjacent sensors from the floor are slightly different, and a plurality of sensors are alternately arranged in a staggered pattern. May be. Furthermore, for the convenience of the housing design of the main body 51, the height from the floor of some of the position sensors 1 to 16 (for example, the sensor near the antenna 54) may be shifted in the vertical direction. Good.
[0022]
Reference numerals 21 and 22 in FIG. 2 denote adult / children sensors for discriminating between adults and children provided at positions slightly above the row of position sensors 1 to 16, which are the second detection means of the present invention. It constitutes an example. One adult / child sensor 21 is a passenger sensor that is provided near the entrance of the automatic ticket gate 50 and enters from the right side of the figure. The other adult / child sensor 22 is a sensor for passengers that is provided in the vicinity of the exit of the automatic ticket gate 50 and enters from the left in the figure. These adult / child sensors 21 and 22 are composed of reflective optical sensors, and project light obliquely upward to receive light reflected by a passerby. L4 in FIG. 4 indicates the optical axes of the adult / children sensors 21 and 22. When the passerby is an adult, because the height is high, the light projected obliquely upward from the adult / child sensor 21, 22 is irradiated and reflected by the adult, and the sensor 21, 22 receives the reflected light. The sensor output is turned on. Thereby, it is detected that the passerby is an adult. On the other hand, when the passerby is a child, because the height is low, the light projected obliquely upward from the adult / child sensor 21, 22 is not irradiated to the child, and the sensor 21, 22 does not receive the reflected light. The sensor output is turned off. Thereby, it is detected that the passerby is a child. That is, the angle of the optical axis L4 is set so that the adult / children sensors 21 and 22 can detect and distinguish between adults and children based on the height of the passersby. Note that the adult / children sensors 21 and 22 may be constituted by transmissive optical sensors. In this case, a transmissive optical sensor that projects light in the horizontal direction may be attached at a position higher than the attachment position of the adult / child sensors 21 and 22 in FIG. In the case of a transmissive sensor, the sensor output is turned on when the light is shielded, and the sensor output is turned off when the light is transmissive (non-shielded).
[0023]
In FIG. 2, 31, 32, 41 are door part child detection sensors provided in the vicinity of the entrance of the automatic ticket gate 50, and the door part child detection sensors 31, 32 are positions above the gate door 52. It is also used as an entry / exit detection sensor. The door part child detection sensor 41 is disposed at a lower position of the gate door 52. Reference numerals 33, 34, and 42 are door part child detection sensors provided near the exit of the automatic ticket gate device 50, and the door part child detection sensors 33 and 34 are located above the gate door 53. It is arranged and also serves as an entry / exit detection sensor. The door child detection sensor 42 is disposed at a lower position of the gate door 53. Each of these sensors 31 to 34, 41, and 42 is composed of a transmissive optical sensor, like the position sensors 1 to 16. 4 indicates the optical axes of the sensors 31 to 34, and L3 indicates the optical axes of the sensors 41 and 42.
[0024]
In FIG. 2, the position sensors 1 to 16 are installed at a height that can detect a passer of the minimum age (first grader) who needs a child ticket. Here, the installation surface of the automatic ticket gate device 50 ( It is installed at a height of about 90 cm from the floor. This height can be detected statistically, for example, so that almost all infants just before entering elementary school can be detected.
h = Average height of a 5-year-old child-3σ (σ: standard deviation)
Is a value lower than the height h calculated from the above. Therefore, the position sensors 1 to 16 can detect both adults and children, and can track each position. Further, even a short child can be reliably detected without being affected by the passing posture. On the other hand, the sensors 31 to 34 are installed at a height of about 70 cm from the installation surface, and the sensors 41 and 42 are installed at a height of about 40 cm from the installation surface. Further, in the case of a reflective sensor that projects obliquely upward as shown in FIG. 4, the adult / child sensors 21 and 22 are installed and adjusted so that a passerby whose height is approximately 120 cm or more can be detected. In addition, when a transmissive sensor that projects light in the horizontal direction is used as the adult / child sensor 21, 22, the sensor is installed at a height of about 120 cm. However, these are only examples, and the installation height of each sensor may be set to an optimum value as necessary.

[0027]
FIG. 6 is a diagram showing an example of the contents stored in the management table 73. In the management table 73, an ID number 73a, position information 73b and 73c, direction information 73d, contact information 73e, determination information 73f, large / small discrimination information 73g, traffic information 73h, and the like are recorded. The ID number 73a is an identification number assigned to each passenger who enters the automatic ticket gate 50. The position information 73b and 73c is information representing the position of the passenger by the status described later. The position information 73b is position information based on the current (updated) status, and the position information 73c is the previous (before update) status. Based location information. The direction information 73d is information indicating which direction the passenger has entered from the automatic ticket gate 50, and in the case of a ticket gate dual-purpose machine, information indicating whether the passenger has entered from the ticket gate side or the ticket collector side. It is. The contact information 73e is information representing the number of people in contact (the number of contacts) and the order in which they are in contact (contact order) when a plurality of passengers come in contact. The determination information 73f is information related to determination of a ticket, and includes a sequence number assigned to the processing of a single ticket, a determination result of validity / invalidity of a ticket, and a distinction between an adult ticket and a child ticket. . The large / small discrimination information 73g is information obtained from the detection results of the adult / children sensors 21 and 22 in FIG. 2, and is information indicating whether the passenger is an adult or a child. The traffic information 73h is information about normal passengers and other abnormal passengers. If the passenger did not present a ticket, a no-passenger, a ticket was presented, but it was not a valid ticket In the case (when the determination result of the determination information 73f is “invalid”), the invalid passenger, in the case of a passenger who has entered from the opposite direction to the permitted entry side, the reverse entry passenger, the passenger's ticket (non-contact) When the ticket processing is not completed because communication between the medium 81) and the automatic ticket gate 50 is interrupted, each flag is set as an unfinished customer, and both are handled as abnormal customers. All other cases are treated as normal customers.
[0028]
With the management table 73 as described above, the position of a person passing the automatic ticket gate 50 is managed in real time for each person. Further, in this management table 73, the location information 73a, 73b of the passers and the determination information 73f of the boarding medium are linked and managed for each passer, so that the number of passing people is inconsistent. No, it becomes possible to perform traffic management without using the calculation by the correct ticket counter. However, the present invention can also be applied to the case where a genuine ticket counter is used, and the presence or absence of the genuine ticket counter is not an essential matter for the present invention.
[0029]
Further, as described above, the position sensors 1 to 16 are arranged in a row at a height of about 90 cm that can detect almost all passers of the minimum age (first graders) who need a child ticket. Children of less than 120 cm (90 cm or more) that cannot be detected by the adult / children sensors 21 and 22 can be tracked and managed. That is, when the passport is a child ticket, if the passerby is not detected as an adult by the adult / child sensor 21, 22, the management table 73 of the child being tracked for the determination information of the ticket ( By linking “children” to the large / small discrimination information 73g), the passerby can be managed as a child, thereby eliminating the inconsistency in the number of passing people, as in the case of subtracting the correct ticket counter. Can do. In addition, by using a bill counter instead of such a determination information link method, it is possible to manage a person who is less than 120 cm (90 cm or more) as a child who cannot be detected by the adult / child sensor 21, 22 as described above. Therefore, the correct ticket counter can be accurately subtracted.
[0030]
Next, the principle of human detection in the automatic ticket gate 50 described above will be described. 7 to 9 are diagrams for explaining statuses and their transitions. The status is position information that groups a plurality of sensors and assigns each group corresponding to the sensor position. For example, as shown in FIG. 7A, the sensor 1 and the sensor 31 provided at intervals in the vertical direction constitute one group, and the status ST1 is assigned to the group. Further, as shown in FIG. 7B, adjacent sensors 1, 2 and sensor 31 constitute one group, and status ST2 is assigned to the group. Further, as shown in FIG. 7C, the adjacent sensors 2 and 3 and the sensor 32 constitute one group, and the status ST3 is assigned to the group. Similarly, as shown in FIG. 7D, the adjacent sensors 3 and 4 and the sensor 32 constitute one group, and status ST4 is assigned to the group.
[0031]
The following statuses ST5 to ST13 are assigned as shown in FIGS. 7 (e) to (f), FIGS. 8 (g) to (l), and FIG. 9 (m). That is, two adjacent sensors constitute one group, and statuses ST5, ST6, ST7,... ST13 are sequentially assigned to each group. In addition, statuses ST14 to ST17 are assigned in the same manner as statuses ST4 to ST1. That is, as shown in FIG. 9 (n), the adjacent sensors 13 and 14 and the sensor 33 constitute one group, and the status ST14 is assigned to the group. Further, as shown in FIG. 9 (o), the adjacent sensors 14 and 15 and the sensor 33 constitute one group, and the status ST15 is assigned to the group. Similarly, as shown in FIG. 9 (p), adjacent sensors 15 and 16 and sensor 34 form one group, and status ST16 is assigned to the group. Finally, as shown in FIG. 9 (q), the sensor 16 and the sensor 34 constitute one group, and the status ST17 is assigned to the group.
[0032]
The CPU 71 monitors the detection signals from the sensors 1 to 16 and the sensors 31 to 34 in the human detection unit 78, and when all the plurality of sensors in one group are outputting detection signals, that is, one group. When the AND condition for the light shielding state of the sensor is established, it is determined that the person is located in the status of the group. The number of sensors shielded by one person varies depending on the width of the human torso, but in the following, for simplicity of explanation, two sensors shielded by one person are adjacent to each other. Assuming only the sensor of
[0033]
Considering the case where a passenger enters from the entrance side of the automatic ticket gate 50, since the sensors 1 and 31 at the entrance are simultaneously shielded from light at the same time, the CPU 71 at this point indicates that the current position of the human is FIG. It is determined that the status ST1 is (a). When the passenger travels along the passage 61, the sensor 2 is in a light-shielded state next. However, as described above, the distance between the sensor 1 and the sensor 2 is smaller than the front and rear width of the human torso, so The sensors 1, 2 and 31 are simultaneously shielded from light, and a detection signal is output from each sensor. Therefore, the CPU 71 determines that the current position of the person is the status ST2 in FIG.
[0034]
When the passenger further proceeds through the passage 61, the sensors 3 and 32 are next in a light-shielded state. However, since the distance between the sensor 2 and the sensor 3 is smaller than the front-rear width of the human torso, the sensor 2 maintains the light-shielded state. Thus, the sensors 2, 3 and 32 are simultaneously shielded from light, and detection signals are output from the sensors. Therefore, the CPU 71 determines that the current position of the person is the status ST3 in FIG. Similarly, when the passenger further proceeds through the passage 61, the sensors 3, 4 and 32 are simultaneously shielded from light, and the CPU 71 determines that the current position of the person is the status ST4 in FIG. When the passenger further proceeds through the passage 61, the sensors 4 and 5 are simultaneously shielded from light, and the CPU 71 determines that the current position of the person is the status ST5 in FIG.
[0035]
Similarly, as the passenger advances through the passage 61, the status changes to ST6, ST7,... ST13 (FIG. 7 (f) to FIG. 9 (m)). When the passenger approaches the vicinity of the exit, the three sensors (13, 14, 33, etc.) including the horizontal sensor and the vertical sensor are simultaneously shielded from light as shown in FIGS. 9 (n) to 9 (p). Thus, the status transits to ST14, ST15, and ST16. Finally, when the passenger reaches the exit, the upper and lower sensors 16, 34 are simultaneously shielded from light as shown in FIG. 9 (q), and the status is determined to be ST17. Thereafter, when the passenger exits the exit, the sensors 16 and 34 are in a translucent state, and the CPU 71 determines that the passenger has left the automatic ticket gate 50.
[0036]
By the way, in the above process, when the CPU 71 determines the status ST1, the CPU 71 assigns an ID number to the passenger who has entered the automatic ticket gate 50, and records the assigned ID number 73a in the management table 73 (FIG. 6). . Further, the CPU 71 manages the position of the person having the ID number with the front end status and the rear end status. That is, when a person passes in the direction of travel from the entrance to the exit, the position where the sensor first changes from the light-transmitting state to the light-blocking state is the front end status, and the position where the sensor first changes from the light-blocking state to the light-transmitting state is End status. The front end status corresponds to the front side of the fuselage, and the rear end status corresponds to the back side of the fuselage. For example, when the sensors 9, 10, and 11 indicated by black circles in FIG. 10 are shielded by humans, the front end status is ST11 and the rear end status is ST10. FIG. 10 shows an example in which the front end position and the rear end position of the passerby are managed by two statuses. However, when the torso width of the passerby is small, one status is used as in the examples of FIGS. In some cases, the front end and rear end can be managed. When the torso width of the passerby is large, the front end and the rear end are managed based on the top and last status among the three or more statuses. The front end status and the rear end status as described above are recorded in the management table 73 as position information 73b and 73c. In this case, the latest status is recorded in the position information 73b, and the previous status is recorded in the position information 73c.
[0037]
Next, status update will be described. The status always transitions one by one in the forward direction or the backward direction, and the CPU 71 updates the status when it is determined that the current status has transitioned to the status of the previous group or the next group. For example, in FIG. 11, the front end status will be described as an example. When the current status is ST11, the next status is ST12 (forward direction) or ST10 (reverse direction), so the status transits to ST12 or ST10. When the status changes to one of the statuses, the status ST11 is updated to the changed status.
[0038]
When the front end status changes from ST1 to ST2 to ST3, and then the rear end status changes from ST1 to ST2, the CPU 71 determines that one person has entered the automatic ticket gate device 50. Further, after the rear end status transitions from ST15 → ST16 → ST17, when ST17 is not established, that is, when one or both of the sensors 16, 34 are in a translucent state, the CPU 71 is one person. Is determined to have left the automatic ticket gate 50.
[0039]
As described above, in the above-described embodiment, the sensor interval (here, 8 cm) is set so that the adjacent sensors of the sensors 1 to 16 detect one person at the same time, and include the adjacent sensors. By grouping a plurality of sensors and assigning status as position information for each group, the status sequentially changes with human traffic. By tracking this transition, the CPU 71 tracks the human position. It can be managed in real time. In addition, since the front end position and the rear end position of a passing person are managed based on the front end status and the rear end status, the sensor position is reached by the front end position, and the sensor position is detected by the rear end position. Each separation can be managed, and the position of a person can be accurately detected.
[0040]
Next, traffic control of the automatic ticket gate 50 will be described with reference to FIGS. 12 and 13. Each figure has shown the detection condition of the sensor when the passer-by M walks the passage, and among the sensors 1-16, 31-34, the black sensor detects the passer-by M and outputs a detection signal. It is a sensor. In each figure, the sensor arrangement corresponds to that in FIG. 2, but the passerby M is viewed from above for convenience.
[0041]
FIG. 12A shows a state immediately after the passerby M enters the passage from the entrance ENT of the automatic ticket gate device 50. At this time, the sensors 1 and 31 closest to the entrance ENT are in a light-shielded state, and the entry of the passerby M is detected. FIG. 12B shows a state where the passer-by M has traveled along the passage and has come to the position of the adult / children sensor 21. At this time, the sensors 2 to 4 and 32 are shielded from light and output a position detection signal. If the passer-by M is an adult, as described above, the adult / child sensor 21 receives the reflected light from the passer-by M and outputs an adult detection signal (ON signal). On the other hand, if the passer-by M is a child, the adult / child sensor 21 does not receive the reflected light from the passer-by M and does not output an adult detection signal. As will be described later, the determination of adult / child is performed based on the sensor output (ON signal) of the adult / child sensor 21, the position of the front passenger, and the position condition of the passerby M.
[0042]
FIG. 13C shows a state in which the passer-by M further travels through the passage and reaches the no-tag detection position. The no-tag detection position is a reference position for determining whether or not the passerby M is a no-card customer, and is set between the center CNT of the passage and the entrance ENT. In the present embodiment, when the front end status of the passerby M reaches ST6 (sensors 5 and 6 light-shielded) and the rear end status reaches ST5 (sensors 4 and 5 light-shielded) as shown, Judgment is made. The no-tag determination is performed based on the presence / absence of the boarding medium determination and the adult / child identification result. For example, when the passerby M (adult) passes the non-contact medium 81 without holding it over the antenna 54, or when the medium information cannot be read because the holding method is not appropriate (hereinafter, this is referred to as "skipping motion"). The determination result of the adult / child is “adult” and the determination result of the boarding medium is “none”, so that the passer-by M is determined to be a billless customer. Processing when it is determined that the customer is a no-tag customer will be described later. In the present embodiment, it is assumed that only the adult non-ticket customers are prohibited from closing the gate door among the non-ticket customers and the non-prohibited traffic is not permitted for the child non-ticket customers. This is because it is difficult to distinguish between a safety reason that closing the gate door itself is dangerous and an infant that does not require a ticket (under 1st grade).
[0043]
FIG. 13D shows a state in which the passer-by M further travels along the passage and approaches the center CNT of the passage. In the present embodiment, it is determined that the passer-by M has reached the center CNT when the front end status of the passer-by M becomes ST8 (sensors 7, 8 light-shielded). At this time, if the passer-by M is an adult and the passenger is determined to be a no-card passenger at the no-tag detection position in FIG. 13C, the exit-side gate door 53 is closed and the passer-by M Unauthorized traffic is prohibited. On the other hand, if the passer-by M is not determined to be a billless customer, the passer-by M is permitted to pass while the gate door 53 on the exit side is left open. Although the case where a passenger enters from the right direction of FIG. 2 has been described above, the detection / determination process is performed based on the same principle as described above even when the passenger enters from the left direction of FIG.
[0044]
FIG. 14 is a diagram for explaining another embodiment of the present invention. In the present embodiment, the detection ranges of the adult / child sensors 21 and 22 are switched between wide and narrow according to the interval between the passerby and the previous customer. As a reference for the interval in this case, it is checked here whether or not the rear end status of the front customer M1 is within ST6 (sensors 5 and 6 shielded). As shown in FIG. 14A, if the rear end status of the front customer M1 is, for example, ST10, the front customer M1 is at a position sufficiently away from the entrance. Absent. Accordingly, in this case, for the next customer M2, a wide range from the position where the front end status is ST1 to the no-tag detection position where the front end status is ST6 and the rear end status is ST5 is defined as a detection range Za. The CPU 71 monitors the output of the adult / child sensor 21 in each status of the detection range Za. If the output of the adult / child sensor 21 is ON (light receiving state) in any status, the CPU 71 determines that an adult is detected at that timing.
[0045]
On the other hand, as shown in FIG. 14B, if the rear end status of the front customer M1 is, for example, ST6, the front customer M1 is close to the entrance. There is a risk of misidentifying children. Specifically, for example, when an adult and a child approach in this order, the subsequent child may be misclassified as an adult due to the posture of the adult of the front customer. Therefore, in this case, for the next customer M2, the narrow range from the position where the front end status is ST3 to the position where the rear end status is ST4 is set as the detection range Zb, and the adult / child in each status of this detection range Zb The CPU 71 monitors the output of the sensor 21. For example, the detection range Zb corresponds to a sensor position passing range when a passenger passes through the installation position of the adult / child sensor 21. If the output of the adult / child sensor 21 is ON (light receiving state) in any status, the CPU 71 determines that an adult is detected at that timing.
[0046]
In the above example, the detection range of the adult / child sensor 21 or 22 is switched according to the timing range in which the CPU 71 refers to the output of the adult / child sensor 21, but can be detected as the adult / child sensor 21, 22. You may make it switch a detection range using the sensor which can adjust an area. As such a sensor, for example, a multi-beam sensor can be used. The multi-beam sensor is a sensor for projecting a plurality of light beams at a predetermined angle to detect reflected light from an object, and sensor output of the plurality of light beams (ON with an object, OFF without an object) The detection range can be switched depending on which beam sensor output is to be referred to. For example, in the case of a multi-beam sensor having three light beams, when the previous customer and the next customer are approaching and it is desired to narrow the detection range, only the central one beam is referred to. In addition, when the previous customer and the next customer are separated and it is desired to widen the detection range, it is determined that an adult has been detected by referring to all three beams and if the sensor output of at least one beam is ON. . When a multi-beam sensor is used, since the detection range of the sensor itself has a width, it is sufficient to fix the position for referring to the sensor output. For example, when the front end status of a passenger reaches ST3, the multi-beam sensor is used. What is necessary is just to refer to the output of the sensor. Instead of this, it is also possible to adopt a method of changing the reference position as described above.
[0047]
By switching the detection range as described above, when the distance from the front passenger is long, the detection range can be widened to enable accurate detection regardless of the passer's posture. That is, when the passerby is an adult, a deviation occurs between the timing when the position sensors 1 to 16 detect the position and the timing when the adult / child sensor 21 detects the adult due to an unnatural posture. Even if the adult / child sensor 21 does not output an adult detection signal when the status is ST3, if the adult / child sensor 21 outputs an adult detection signal when the front end status is ST5, for example, Can be determined. On the other hand, when the distance from the front passenger is close, narrowing the detection range eliminates the possibility of erroneous detection of adults / children before and after the passenger as described above, and enables accurate detection. .
[0048]
FIG. 15 is a flowchart showing the operation of the automatic ticket gate 50, showing the procedure executed by the CPU 71 in accordance with the control program PRG. The CPU 71 first checks the detection outputs of the sensors 1 to 16, 31 to 34 (step S1), and determines whether or not there has been a status transition based on the presence or absence of the detection output (step S2). If there is no status transition (step S2: NO), the process returns to step S1 to continue checking the detection output of the sensor. If there is a status transition (step S2: YES), the current position information 73b and the previous position information 73c in the management table 73 are updated (step S3). In this case, the front end status and the rear end status recorded in the current position information 73b immediately before the update are moved to the previous position information 73c, and the latest (current) front end status is always included in the current position information 73b. And the trailing end status is recorded.
[0049]
Next, with reference to the front end and rear end statuses of the updated current position information 73b, it is determined whether or not the current position of the passenger is between the entrance and the no-tag detection position (step S4). If the current position is between the entrance and the no-tag detection position (step S4: YES), it is determined whether the passer is an adult or a child based on the outputs of the adult / child sensors 21 and 22 ( Step S5). This discrimination result is recorded in the management table 73 as size discrimination information 73g. Details of step S5 will be described later. If the current position is not between the entrance and the no-tag detection position (step S4: NO), step S5 is skipped. Next, it is determined whether or not the current position of the passenger is a no-tag detection position (step S6). As described above, when the front end status reaches ST6 and the rear end status reaches ST5, it is determined that the passenger has arrived at the no-tag detection position. In step S6, is this condition satisfied? Check whether or not. If the passenger's current position is not the tagless detection position (step S6: NO), it is next determined whether or not the passenger's current position is the center position (step S7). In the present embodiment, when the front end status reaches ST8 as shown in FIG. If the current position is not the center position (step S7: NO), it is subsequently determined whether or not the vehicle has left (step S8). As described above, after the rear end status transits to ST17, it is determined that the vehicle has exited when ST17 is not established due to the light transmission of the sensors 16, 34. If the exit has not been completed (step S8: NO), the process returns to step S1 and the above-described procedure is repeated.
[0050]
If it is determined in step S6 that the current position is the no-tag detection position (step S6: YES), then it is checked whether the antenna 54 reads the boarding medium (non-contact medium 81) to determine whether or not the vehicle can pass. (Step S9). If the boarding medium is normally held over the antenna 54, the data such as the boarding section recorded in the boarding medium is read to determine whether or not the vehicle is allowed to pass (step S9: YES). 73 is recorded as determination information 73f (step S10). On the other hand, when the above-mentioned idling motion occurs because the boarding medium is not held over the antenna 54 or the way of holding is not appropriate, the data of the boarding medium is not read and determination is not performed (step S9: NO). It is determined that the passenger is entering without a bill, and the large / small discrimination information 73g of the management table 73 is referred to (step S11). As a result, if the passenger is an adult (step S11: YES), the passenger is treated as a no-ticket customer (occurrence of no-card anomaly), and the no-ticket customer flag in the traffic information 73h of the management table 73 is turned ON. The message display unit 56 displays a guide indicating that there is no bill (step S12). At this time, an alarm chime may be sounded together with the display. Alternatively, instead of the guidance display or in addition to the guidance display, it may be guided by voice that there is no bill. After executing Step S10 or Step S12, the process returns to Step S1. On the other hand, if the large / small discrimination information 73g is not an adult in step S11 (step S11: NO), it is considered that the child has entered without a bill and is not treated as a billless customer, and the process returns to step S1.
[0051]
Note that at the stage where it is determined that there is no bill in step S9, the gate door 53 is not yet closed and is kept open. And if the passenger who knew that there was no bill by the guidance display of the message display unit 56, retreats in the passage, returns to the entrance side, holds the boarding medium over the antenna 54, and if the determination result is normal, the passenger It is possible to exit from an exit through which the gate door 53 is open. Here, after displaying the billless guidance, it is up to the position of the passenger that the passenger moves backward in the aisle, and whether or not the redo is permitted depends on the specifications of the device. For example, the specification may be such that the passenger once exits the passage completely and restarts the riding medium, or the passenger can perform the holding operation again at a position slightly returned without exiting the passage completely. .
[0052]
When the passenger who has passed through the no-tag detection position reaches the center position (step S7: YES), referring to the traffic information 73h recorded in the management table 73, whether the passenger is a no-card passenger who does not have a boarding medium. Is determined (step S13). The passenger who arrived at the center position did not notice that there was no bill without seeing the guidance display on the message display section 56, or the adult passenger who saw the guidance display but ignored it and tried to pass If the passenger is a passenger, since the no-tag customer flag of the traffic information 73h is ON, the determination in step S13 is YES, the gate door 53 is closed and traffic is prohibited (step S14), and the process returns to step S1. Thereafter, the same processing as described above is executed. On the other hand, if it is determined in step S13 that the customer is not a billless customer (step S13: NO), the passage is permitted (the gate door 53 is left open) and the process returns to step S1. After that, if it is determined that the user has left in step S8 through steps S2 to S7 (step S8: YES), the process is terminated.
[0053]
In the example of FIG. 15 described above, the gate door 53 is not closed when the no-tag is determined at the no-tag detection position, and when the no-card customer reaches the center position, the gate door 53 is closed and the no-card customer. However, it is also possible to close the gate door 53 and prohibit the passage of no-tag customers when no-tag is determined at the no-tag detection position. In this case, when the passer-by reaches the no-tag detection position and the determination result in step S9 is NO (no-ticket customer), the large / small discrimination information 73g of the management table 73 is referred to, and the passer-by If it is an adult, the gate door 53 may be closed immediately.
[0054]
In the example of FIG. 15, the no-ticket customer flag of the traffic information 73h of the management table 73 is set to ON only in the case where the no-tag is an adult in step S11. The tagless customer flag is turned on and managed as a child ticketless customer. In the determination of step S13 at the central position, the large / small discrimination information 73g and the tagless flag of the traffic information 73h are referred to with an AND condition. Thus, the gate door 53 may be closed when the large / small discrimination information 73g is “adult” and the no-tag customer flag of the traffic information 73h is “ON”.
[0055]
FIG. 16 is a flowchart showing the procedure of the adult / children discrimination process in step S5 in FIG. First, it is checked whether or not the outputs of the adult / children sensors 21 and 22 are ON (step S21). In the case of a reflective sensor, the outputs of the adult / child sensors 21 and 22 are ON when the sensor is in a light receiving state and OFF when the sensor is in a non-light receiving state. If the sensor output is OFF (step S21: NO), the process is terminated without performing the subsequent processes, and the process proceeds to step S6 in FIG. If the sensor output is ON (step S21: YES), it is determined that an adult has entered, and then whether or not the rear end status of the front customer is within ST6 based on the detection outputs of the position sensors 1-16. Is determined (step S22).
[0056]
If the rear end status of the front customer is not within ST6 (step S22: NO), it is determined based on the detection outputs of the position sensors 1 to 16 whether or not the position of the customer who has entered satisfies the condition 1 (step S25). ). Here, the condition 1 is that the position of the customer who has entered from the position at which the front end status has reached ST1 to the position at which the front end status has reached ST6 and the rear end status has reached ST5 (no-tag detection position). It means that it is in the section. If the position of the customer who has entered is anywhere in this section (step S25: YES), “adult” is recorded in the large / small discrimination information 73g of the management table 73 (step S24). In this case, adult detection is performed for the wide detection range Za in FIG. If the position of the entering customer is not within the section of condition 1 (step S25: NO), the adult / child sensor 21, 22 detected in step S21 is a baggage, the head of the previous customer, etc., not an adult. (The detected output is regarded as noise and ignored), and the process ends without executing step S24, and proceeds to step S6 in FIG. In addition, in the large / small discrimination information 73g of the management table 73, “child” is recorded in the initial state, and “child” is rewritten to “adult” when an adult is detected. Therefore, until the adult / child sensor 21, 22 detects an adult, the CPU 71 manages the passerby as a child.
[0057]
On the other hand, if the rear end status of the front customer is within ST6 in step S22 (step S22: YES), it is determined based on the detection outputs of the position sensors 1 to 16 whether or not the position of the customer that has entered corresponds to the condition 2. (Step S23). Here, the condition 2 indicates that the position of the customer who has entered is within the section from the position where the front end status has reached ST3 to the position where the rear end status has reached ST4. If the position of the customer who has entered is in any one of the sections (step S23: YES), “adult” is recorded in the large / small discrimination information 73g of the management table 73 (step S24). In this case, adult detection is performed for the narrow detection range Zb in FIG. If the position of the entering customer is not within the section of condition 2 (step S23: NO), the adult / child sensor 21, 22 detected in step S21 is a baggage, the head of the previous customer, etc., not an adult. (The detected output is regarded as noise and ignored), and the process ends without executing step S24, and proceeds to step S6 in FIG.
[0058]
In the embodiment described above, the position and the adult / child are not discriminated by simultaneous shading of the upper and lower sensors as in the prior art, but the position of the passerby is detected and tracked by the columnar position sensors 1 to 16, The adult / children sensors 21 and 22 are used only for discrimination of passersby adults / children. By separating the position detection sensor and the adult / child discrimination sensor in this manner, the position detection timing by the position sensors 1 to 16 and the adult / child sensor 21 and 22 are determined according to the passing posture of the passerby. Even if there is a deviation from the adult detection timing, once the sensors 21 and 22 detect an adult, the position sensors 1 to 16 can track and manage the customer as an adult. Therefore, for example, it is possible to accurately detect and manage adults / children even for passengers who travel in an unnatural posture.
[0059]
Further, by separating the position detection sensor and the adult / children discrimination sensor, the positions of the adult / children sensors 21 and 22 in the passage direction are not restricted, and the adult / children sensor 21 is located near the entrance of the passageway. , 22 can be provided. As a result, when the passer-by reaches the no-tag detection position or the center position, since the discrimination of adult / child is already completed, it cannot be determined that the passenger is a child until the previous passenger reaches the exit as in Patent Document 1. Therefore, it is possible to reliably prevent illegal traffic due to no bills.
[0060]
【The invention's effect】
As described above, according to the present invention, it is possible to reliably prevent unauthorized traffic without a bill by accurately performing traffic management.
