Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic ticket gate such as that installed at a ticket gate of, for example, a railway or an airport. More specifically, the present invention relates to an automatic ticket gate that accurately detects adults, children, and passers with large behaviors having different sizes.
[0002]
[Prior art]
In general, this type of automatic ticket gate detects the pass-by state of a passer by a plurality of photoelectric detection sensors disposed on the inner surface of the passage of the ticket gate body.
Further, depending on the installation position of the automatic ticket gate such as adjacent to the staff counter, as shown in FIG. 15, a barless type ticket gate main body 151 is provided, so that the detection direction is not in the horizontal direction but in the ticket gate passage 152. An appropriate passer-by 154 who properly passes through the center of the passage is detected by an inclination detection sensor 153 for detecting the height in which the detection direction is set to be inclined toward the upper center.
[0003]
However, in this case, when the passerby is biased to one side of the ticket gate passage 152, the passerby 155 deviates from one of the inclination detection areas 153 a and cannot be detected as a person. In addition, even when an unpaid infant or child 156 is biased, it enters the other inclination detection area 153b and is erroneously detected as an adult.
[0004]
In this way, when detected by the inclination detection sensor for height detection used in the automatic ticket gate, this detection output is detected by the binary value of ON / OFF, and only the presence or absence of paying customers is detected, so the detection area is adjusted. If it is not set strictly, there is a possibility that the automatic ticket checker malfunctions due to an erroneous detection of the detection sensor by an object or a person outside the passage of the automatic ticket checker. In addition, there was a risk that two free children traveling side by side were mistakenly judged as one paying customer and the door unexpectedly hit the passerby.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention not only detects the presence or absence of a vehicle, but also incorporates the detection distance from the detection sensor to the vehicle to the detection condition, so that various passers-by such as biased traffic and child-lined traffic can be used. The purpose is to provide an automatic ticket gate with improved safety to accurately detect the traffic state of the car.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 is an automatic ticket gate that controls ticket gates based on traffic detection data of a detection sensor that detects a passing body passing through the ticket gate passage, wherein the detection sensor detects diagonally upward or substantially horizontally. Measuring means for calculating the detection distance in the passage width direction to the passing body based on the acquired traffic detection data, and the detection distance is an internal invalidity detection near the detection sensor. And determining means for determining that the traffic detection data is valid if it is within an effective detection distance excluding the area and the external invalidity detection area in the external space from the ticket gate passage .
[0007]
According to a second aspect of the present invention, the detection sensor detects the traffic detection data obliquely upward, the measurement means calculates the height of the traffic body based on the traffic detection data, and the determination means. Is characterized in that the traffic detection data is determined to be valid if the determination condition is satisfied and the height is equal to or higher than a preset pay height .
[0008]
According to a third aspect of the present invention, the detection sensors are provided on both the left and right sides of the ticket gate, and the measuring means also calculates a lateral width of the vehicle based on the traffic detection data by the detection sensors on the left and right sides, and the determination The means is characterized in that the traffic detection data is determined to be valid if the determination condition is satisfied and the horizontal width is equal to the number of persons permitted to use the ticket gate .
[0009]
According to a fourth aspect of the present invention, the determination means determines whether or not the passing body passes through the central portion of the ticket gate passage based on the detection distance in the passage width direction, and determines that the passage is passing through the central portion. In this case, it is determined that the ticket gate usage state is appropriate .
[0010]
[Action and effect of the invention]
According to the present invention, when the detection sensor detects a passing body that passes through the ticket gate passage, the measurement means calculates the detection distance to the passing body, and the detection distance includes the internal invalid detection area near the detection sensor and the above-described detection distance. The traffic detection data is determined to be valid only when it is within the effective detection distance excluding the external invalidity detection area in the external space from the ticket gate . Therefore , it is determined that the vehicle is in a proper traffic state when it is used appropriately, and in other cases , it is handled as invalid data and the detection data can be handled accurately.
[0011]
Also, when calculating the detection distance to the vehicle, the height of the vehicle is calculated based on this, and if the setting is made to determine the effectiveness of the vehicle according to this height calculation result, the height difference The distinction between adults and children with different age can be accurately judged.
[0012]
Also, when calculating the detected distance to the traffic body, this was calculated the width of the traffic object based, is set to determine the effectiveness of traffic body in accordance with the width calculation result, the width of the passage body Can be accurately captured.
[0013]
Furthermore, when the detection distance to the vehicle is calculated , the width-direction traffic position of the vehicle is calculated based on the detection distance, and if the vehicle is set to determine the effectiveness of the vehicle according to the traffic position, The traffic condition in the width direction can be accurately detected.
[0014]
In this way, because it has a high detection capability to detect a passing object using the detection distance to the passing object as a detection condition, it does not require strict adjustment of the detection area, and it eliminates false detections and malfunctions naturally, and safety High automatic ticket gates are possible.
[0015]
【Example】
An embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a barless type automatic ticket gate 11, and this barless type automatic ticket gate 11 is configured with a ticket gate passage 14 between an opposing part of one ticket gate main body 12 and the other ticket gate main body 13 facing left and right. In addition, doors 15 that open and close are disposed on the inner surfaces of the passages at both ends of both of the ticket gate bodies 12 and 13, and a ticket, a commuter pass, etc. A ticket insertion slot 16 for inserting the boarding ticket is opened, and a ticket discharge slot for discharging the ticket and a guidance display for displaying the ticket gate usage guide are provided on the back side of the upper surface.
[0016]
Further, reflection type upper detection sensors Sr and Sl for photoelectric detection from the right and left sides of the ticket gate main body 12 and 13 are arranged on the upper side of the ticket gate passage 14 from the left and right sides. The space is photoelectrically detected.
[0017]
In this case, both upper detection sensors Sr and S1 set the central upper space of the ticket gate passage 14 to the effective detection area A1, and the inclination detection light beams 17 and 18 photoelectrically detect the effective detection area A1. An external space that is invalid for detection other than the effective detection area A1 is set as the external invalidity detection area A2, and a wall near the detection invalidity near the sensor is set as the internal invalidity detection area A3.
[0018]
In setting the effective detection area A1, the effective detection distances of the tilt detection light beams 17 and 18 are measured and set.
Effective detection distance corresponding to the effective detection area A1: L1
External invalidity detection distance corresponding to external invalidity detection area A2: L2
Internal invalid detection distance corresponding to internal invalid detection area A3: L3
Then, this effective detection distance L1 is
L3 <L1 <L2
Is required.
[0019]
For this reason, it is handled as valid data only when the effective detection distance L1 is measured, and it is handled as invalid data when the external invalid detection distance is not less than L2 and the internal invalid detection distance is not more than L3. Can be handled. Therefore, when the ticket gate passage 14 is detected, it is possible to automatically select the detection element of the detection data and confirm that the data is appropriate.
[0020]
The barless type automatic ticket gate 11 has a common ticket gate function that allows the ticket gate 14 to be checked from both sides, and a similar detection function can be provided regardless of whether the passer is passing in the normal direction or the reverse direction. Work and accurately detect passers-by.
[0021]
FIG. 2 shows a control circuit block diagram of the barless type automatic ticket gate 11. The CPU 21 controls each circuit device in accordance with a program stored in the ROM 22 and stores the control data in a readable manner in the RAM 23.
[0022]
The upper detection sensors Sr and S1 disposed on the left and right sides detect the passage state of the upper space of the ticket gate passage obliquely above, and the lower detection sensor 24 disposed on the lower inner surface of the ticket gate passage 14 also detects the lower space of the ticket gate passage. Detect the traffic condition of. In addition, the ticket gate guidance information of the passers-by is displayed on the guidance display device 25 disposed on the upper surface of the ticket gate main body.
[0023]
The ticket processing unit 26 reads the magnetic data of the ticket inserted into the ticket insertion slot 16 to determine its validity. When it is determined to be valid, the ticket processing operation such as magnetic data processing, printing processing, punch hole formation, etc. Execute. Further, the entrance door processing unit 27 and the exit door processing unit 28 open / close each door 15 based on the door control signal of the CPU 21 to allow / restrict passers-by who use the ticket gate.
[0024]
By the way, when the left and right upper detection sensors Sr and Sl acquire the detection data, the CPU 21 calculates the detection distance from the sensor to the detection position at the same time, and if the calculated value is recognized as the effective detection distance L1, the detection is performed. It is determined that the data is valid, and the detection operation is performed after confirming an appropriate detection target. In addition, the height and width of the passerby passing through the ticket gate and the passage position in the passage width direction can be accurately obtained. Therefore, it is possible to identify and catch only the passerby using the ticket gate 14 and to accurately detect the passing state.
[0025]
The ticket gate processing operation of the barless type automatic ticket gate 11 configured as described above will be described with reference to the flowchart of FIG.
Now, when a passer-by passes through the ticket gate 14 and uses the ticket gate, not only the lower detection sensor 24 but also the upper detection sensors Sr and Sl detect the passer-by, and at this time, the CPU 21 detects the sensor based on the upper detection data. Calculate the detection distance in the passage width direction from the side of the passage of Sr, Sl to the passerby (step n1),
When it is determined that a passerby exists in the effective detection area A1 detected at the appropriate effective detection distance L1 as a result of the calculated detection distance (steps n2 to n3),
The CPU 21 can determine that the person is a legitimate person to be detected that passes through the ticket gate 14 and can accurately detect the person by checking the person who has passed (steps n4 to n5).
[0026]
When the CPU 21 calculates the detection distances of the upper detection sensors Sr and Sl, if it is greater than or equal to the external invalid detection distance L2 outside the ticket gate passage 14, it is treated as invalid data because it is outside the valid detection distance L1, and from the ticket gate passage 14 as well. When the internal invalid detection distance L3 near the sensor in front is less than the effective detection distance L1, it is handled as invalid data (steps n6 to n7).
[0027]
FIG. 4 shows a single barless type automatic ticket gate 41. This single barless type automatic ticket gate 41 has a reflection type upper detection sensor 44 attached to a bar 43 standing on the upper part of one of the bar-equipped ticket gate main bodies 42, and this upper part. The upper space of the ticket gate passage 45 is photoelectrically detected from the detection sensor 44 substantially horizontally.
[0028]
In this case as well, when setting the effective detection area A1, the effective detection distance of the horizontal detection light ray 46 is measured and set.
Effective detection distance corresponding to the effective detection area A1: L1
External invalidity detection distance corresponding to external invalidity detection area A2: L2
Internal invalid detection distance corresponding to internal invalid detection area A3: L3
Then, this effective detection distance L1 is
L3 <L1 <L2
Is required.
[0029]
Thus, even if it is applied to the one-barless automatic ticket gate 41, since the detection distance is set as the detection condition, the detection data can be handled accurately and the same effect can be obtained.
[0030]
FIG. 5 shows a bar-type automatic ticket gate 51. The bar-type automatic ticket gate 51 has a reflection-type upper detection sensor 54 attached to a bar 53 standing on the upper side of one of the ticket gate main bodies 52. Photoelectric detection is performed toward the upper space of the ticket gate passage 55.
[0031]
In this case as well, when setting the effective detection area A1, the effective detection distance of the horizontal detection light beam 56 is measured and set.
Effective detection distance corresponding to the effective detection area A1: L1
External invalidity detection distance corresponding to external invalidity detection area A2: L2
Internal invalid detection distance corresponding to internal invalid detection area A3: L3
Then, this effective detection distance L1 is
L3 <L1 <L2
Is required.
[0032]
Thus, even when applied to the bar-type automatic ticket gate 51, since the detection distance is set as the detection condition, the detection data can be handled accurately and the same effect can be obtained.
[0033]
Next, the processing operation when one paying customer uses the ticket gate and two free children simultaneously using the ticket gate using the barless type automatic ticket gate 11 will be described with reference to the flowchart of FIG.
Now, when the passerby uses the ticket gate, the upper detection sensors Sr and Sl in addition to the lower detection sensor 24 acquire detection data at the time of passing, and at this time, the CPU 21 passes the passages of the sensors Sr and Sl based on the upper detection data. Calculate the detection distance in the passage width direction from the side to the passerby (steps n11 to n12)
Further, the CPU 21 calculates the height of the passer-by based on the calculated detection distance. In this case, as shown in FIG. 7, whether or not the passerby 71 has a width W of one person based on the data of both detection distances obtained from the left and right, and whether the passerby 71 is taller than the paying height H or not. Whether or not (steps n13 to n14),
If it is determined that the passer has a width W for one person and has a height equal to or higher than the paying height H, the ticket gate is confirmed to be used by one paying customer (step n15). At this time, if it is determined that the paying customer uses the ticket gate without a ticket, the gate on the exit side is closed to restrict the ticket gate (steps n16 to n18).
[0034]
On the other hand, when a ticket is used by a paying passenger, a ticket gate is used based on the ticket data (step n19).
[0035]
When the left and right upper detection sensors Sr and Sl detect a passerby whose height is less than or equal to the paid height, the left and right detection data are compared (step n20),
If only the data of one upper detection sensor can be obtained, it is determined that one free child has used the ticket gate (step n21).
[0036]
On the other hand, when the detection data of the left and right upper detection sensors Sr and Sl are obtained, as shown in FIG. 8, the passers-by 81 are two children in parallel based on the data of both detection distances obtained from the left and right. After confirming that the width is equal to W, it is determined that two free children have used the ticket gate simultaneously (step n22).
[0037]
Therefore, in this case, until the two free children in parallel pass through the ticket gate 14, the door 15 is held open and the ticket gate is safely passed (step n 23).
[0038]
Next, refer to the flowchart of FIG. 11 for processing operations when one paying customer uses the ticket gate and two paying customers use the ticket gate simultaneously using the bar-type automatic ticket gate 91 shown in FIGS. To explain.
Now, when the passer-by 92 uses the ticket gate 93, the upper detection sensors Sr and Sl in addition to the lower detection sensor acquire the detection data at the time of passing. At this time, the CPU detects the same sensor based on the upper detection data. Calculate the detection distance in the passage width direction from the side of the passage of Sr, Sl to the passerby (steps n31 to n32),
Further, based on the calculated detection distance, the CPU determines whether or not a passerby has a lateral width W1 based on both detection distance data obtained from the left and right (steps n33 to n34).
As shown in FIG. 9, if it is determined that the width is W1 for one person, it is confirmed that the ticket gate is used by one paying customer (step n35).
[0039]
On the other hand, as shown in FIG. 10, if the passerby 101 determines that the width W2 is equal to two, it is confirmed that two paying customers use parallel ticket gates (step n36).
When one paying passenger uses a ticket, the ticket gate is used based on the ticket data (steps n37 to n39).
[0040]
On the other hand, if two paying passengers use a parallel ticket gate, check whether two tickets have been inserted and confirm that two passengers have been inserted. The use of the parallel ticket gate is permitted (step n40).
If only one ticket is inserted when using this parallel ticket gate, it is determined that two paying passengers are illegally using the ticket gates, and ticket gates are restricted even if one paying passenger is an invalid ticket ( Step n41).
[0041]
Next, processing operations when a paying customer uses a ticket gate using the bar-type automatic ticket gate 121 shown in FIGS. 12 and 13 will be described with reference to the flowchart of FIG.
Now, when the passer-by 122 uses the ticket gate 123, the upper detection sensors Sr and Sl in addition to the lower detection sensor acquire detection data at the time of passing. At this time, the CPU detects the same sensor based on the upper detection data. The detection distance in the passage width direction from the passage side surface of Sr, Sl to the passerby is calculated (steps n51 to n52),
At this time, from the calculated detection distance, the CPU determines whether or not the passer-by 122 is passing through the central portion of the ticket gate passage 123 (step n53),
As shown in FIG. 12, when it is determined that the passer-by 122 is passing through the central part of the ticket gate passage 123, a normal gate control is performed by synchronizing the left and right doors for proper use of the ticket gate. Permit or restrict ticket gates (step n54).
[0042]
On the other hand, when the passer-by 122 passes in the width direction of the ticket gate passage 123, for example, when it is determined that the passer is biased to the right side of the ticket gate passage 123, it is necessary to control the ticket gate for the passer-by. Occasionally, the closing speed of the right door is slowed, door opening / closing control is performed in accordance with the passing state of the passerby, and ticket gate regulation is performed for the safety of the passerby (steps n55 to n56).
[0043]
Also, as shown in FIG. 13, if the passer-by 122 is biased to the left side of the ticket gate passage 123, the closing speed of the left door is slowed when the ticket gate restriction is required, and the passer-by state The door opening / closing control is performed in accordance with the control of the ticket gates for the safety of passers-by (step n57). In addition to the slow closing operation of the door, the door opening / closing control corresponding to the passage position in the passage width direction of the passerby can be performed by changing the door closing angle. The risk of hitting the door can be reduced.
[0044]
As described above, when the upper detection sensor detects the inside of the ticket gate divided into a certain area, the detection distance in the passage width direction from the side of the passage to the object to be detected is measured at the same time, and this detection distance measurement Since it is possible to determine whether the detection data is valid or invalid based on the result, it can be confirmed in advance that the detection data is appropriate. For this reason, the height of the passers through the ticket gate, the width of the passers and the passage position in the direction of the passage width are accurately known, and the opening / closing operation of the automatic ticket checker is accurately detected by accurately detecting the pass state of the passers. It can be carried out. In particular, if it is determined that the traffic detection data is valid and handled only when the effective detection distance of the passer is measured, it is determined that the traffic is properly used when it is used properly, and invalid for other invalid detection distances. Can be handled as data.
[0045]
In addition, when measuring the detection distance to the passerby, the height of the passer is calculated based on this, and if the effectiveness of the passer is determined according to this height calculation result, Can distinguish children accurately. In addition, when the distance to the passerby is measured, the lateral width of the passer is calculated based on this, and if the passerby's effectiveness is determined according to the result of the lateral width calculation, the lateral width of the passer is accurately captured. be able to. Further, when the detection distance to the passer is measured, the passer's width direction pass position is obtained based on this, and if the passer's effectiveness is determined according to the passer's position, the passer's width pass is determined. The state can be accurately detected. In this way, because it has a high detection capability to detect the passerby using the detection distance to the passerby as a detection condition, it does not require strict adjustment of the detection area, and it eliminates false detections and malfunctions naturally, and safety High automatic ticket gates are possible.
