Abstract

PROBLEM TO BE SOLVED: To enable followup detection by providing a wide ranging detection performance without arranging many detection sensors by dividing one light source into plural parts, detecting the presence/absence of reflected light and judging the existence of object. SOLUTION: A flood beam 32 flooded from a flood element 41 as one light source is guided through a flood lens 33 to a slit 34 for flood beam division and divided in three, for example, and the light is flooded in the directions of detection at a wide angle while changing optical axes by 1st-3rd optical axis change boards 35-37. Then, 1st-3rd reflection boards 39-41 are arranged at respective positions on a counter wall surface 38 corresponding to the reflection for every optical axis, reflected received beams 42 are returned to the 1st-3rd optical axis change boards 35-37, guided to a photodetector lens 43 and photo-detector by 1st-3rd photodetectors 44-46 and three detection areas are detected. Thus, since the detection areas over the wide range can be formed by one light source, the positions and moving directions of objects such as luggage or person moving on a passage can be exactly detected. Besides, since one light source is dividedly utilized, beam interference can be canceled, it is not necessary to adjust the optical axes of respective beams, and also the number of sensors can be reduced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ticket gate installed at a ticket gate of a railway, an airport, an event venue, etc., and more particularly, a simplification and a high-performance detection structure for detecting a passerby who uses the ticket gate. The present invention relates to an automatic ticket gate having detection performance.

[0002]

2. Description of the Related Art An automatic ticket gate installed in station service will be described below as an example. As shown in FIGS. 12 and 13, for example, as shown in FIG. 12 and FIG.
The magnetic ticket inserted in the card is read and the passage outlet 122 is provided.
Further, when the contactless card is used at the ticket gate, the data is processed by making the communication control device 123 at the entrance of the passage correspond to the communication. In addition, in order to detect the passerby 124, usually four transmission type photoelectric detection sensors 125 are provided in the handrail frame 127 along the ticket passage 126, and the device main body 1 is provided.
Six of them are arranged in 28 to detect and confirm the passage of the passengers 124. In addition, the ticket gate 129 is accompanied by the data processing result of these magnetic tickets and non-contact cards and the detection confirmation of the passerby.
Opening and closing is controlled.

In this case, since the ticket processing is performed in such a manner that the movement of the magnetic ticket and the movement of the passerby are interlocked with each other, the ticket gate operation is performed in such a manner that the opening / closing operation timing of the ticket gate accurately corresponds to the passing state of the passerby. However, if one person inserts two tickets, a transit ticket and a transit ticket, and uses the ticket, or if such two passengers continue, forgetting to insert the ticket or inserting the next passenger If it is delayed, the correspondence between the customer and the ticket may not be taken accurately, and it may become undetectable.

Similarly, when a contactless card is used, there are various behaviors of the passenger at the ticket gate, such as the passenger temporarily evacuating from the ticket passage and reconsidering the contactless card. Correspondence between customer and card cannot be taken accurately,
It may become undetectable. For this reason, the door of the automatic ticket gate is likely to be congested, such as causing malfunction of the ticket gate or closing the door for an unnecessarily long time to obstruct the ticket gate of the next customer.

Therefore, as shown in FIG. 14, it is considered that a large number of detection sensors 142 ... Are arranged along the ticket gate passage 141 in the passage direction to accurately detect the movement of the passerby. Due to the influence of passengers' limbs, baggage, etc., it is difficult to judge the detection of passing passengers at the entrance / exit of the aisle, and a large change is required to install many detection sensors from the entrance to the aisle of the aisle. In addition, there is a problem that light interference occurs between the detection areas of the detection sensors, it is difficult to adjust the optical path of each of the detection sensors on the light emitting side and the light receiving side, and the cost is increased due to the additional configuration of the sensors.

[0006]

Therefore, the present invention focuses on the follow-up detection of an object moving in a passage, and does not provide many detection sensors but divides one light source to detect a wide area. It is an object of the present invention to provide an automatic ticket gate with performance and capable of detecting follow-up.

[0007]

According to the first aspect of the present invention,
Dividing means for dividing one light source into a plurality of parts, detecting means for detecting the presence or absence of reflected light with respect to the light divided by this dividing means, and determining the presence of an object based on the presence or absence of reflected light detected by this detecting means It is an automatic ticket gate equipped with a judging means for

According to a second aspect of the present invention, there is provided a splitting means for splitting an object moving in the passage so that it can be detected by any optical axis.

According to a third aspect of the present invention, there is provided a dividing means for dividing the light source so as to detect the opening / closing operation area of the door which opens / closes corresponding to the object moving in the passage.

The invention according to claim 4 is characterized in that the reflected light from the return reflection plate provided on the other side facing the light source provided on the one side opposite to the light source is set as the reflected light. .

According to a fifth aspect of the present invention, there is provided follow-up detection means for detecting the moving direction of the object moving in the passage.

[0012]

According to the present invention, one light source is divided into a plurality of pieces by the dividing means, and the judging means detects the presence / absence of an object based on the detection means detecting the presence / absence of reflected light with respect to the divided light. to decide. Further, when dividing the light source, an object moving in the passage is divided so that it can be detected by any optical axis.

Similarly, when the light source is divided, the opening / closing operation area of the door that opens / closes corresponding to the object moving in the passage is divided so that the optical axis can be detected. Further, a light ray reflected from a regressive reflection plate provided on the other side facing the light source provided on the one side with the passage interposed therebetween is regarded as reflected light for detecting an object.

When detecting the presence of an object, the direction of movement of the object moving in the passage is detected by the follow-up detecting means to detect the presence of the object.

[0015]

As a result, since a wide range of detection area can be formed by one light source, it is possible to accurately detect the position and moving direction of an object such as baggage or a person moving in the passage. Also, because of the detection configuration that uses one light source separately,
The light beam interference can be eliminated, the optical axes of the respective detection light beams need not be adjusted, and the number of sensors installed in the entire passage can be reduced to reduce the cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIGS. 1 and 2 show an automatic ticket gate installed in railway station affairs. This automatic ticket gate has the ticket gates 12 and 12 at front and rear positions of the ticket gate body 11 in the direction of the ticket gate, and the magnetic ticket on the upper surface. A slot 14 for inserting / removing 13 and an outlet 15, a transmission control device 17 for reading the boarding data of the contactless card 16 in a contactless manner and processing a ticket gate, and a guide display for displaying the guide information at the ticket gate in characters. And a ticket gate passageway 19 formed between the ticket gate main bodies 11 that are parallel to the left and right.
The first to ninth passage detection sensors S1 to S9 are arranged along the route, and the passage control is performed based on the ticket data used at the ticket gate and the detection signal of the passerby 20 who used the passage.

The above-mentioned first to ninth traffic detecting sensors S1 to S
9 is the first passage detection sensor S1 on the front of the ticket gate body 11.
Is installed to detect the passerby 20 before entering the passage, and the second to sixth passage detection sensors S are provided in the passage direction on the inner side of the ticket gate body 11.
2 to S6 are provided to detect the passing passengers 20 in the ticket gate passage 19, and the seventh to ninth passage detection sensors S are mounted on the handrail frame 21 which is longly installed along the upper gate direction of the ticket gate main body 11.
Passengers 2 in the ticket gate passage 19 with 7 to S9 installed
0 is detected.

FIGS. 3 and 4 show the principle of detection of the first to ninth traffic detection sensors S1 to S9. This detection principle projects a light beam 32 projected from a light projecting element 31 as one light source. The light is guided through a lens 33 to a slit 34 for splitting a projected light beam, and for example, when divided into three, three projected light beams 32
The optical axes are changed by the first to third optical axis changing plates 35 to 37 to project the light in the wide-angle detection direction, and the first to third reflecting plates are provided at the respective positions of the opposing wall surface 38 corresponding to each optical axis. 39 to 41 are arranged, and the three light receiving lines 42 reflected from the reflecting plates 39 to 41 are returned to the original first to third optical axis changing plates 35 to 37 and guided to the light receiving lens 43 to receive the light. The first to third light receiving elements 44 to 46 are caused to receive light from the lens 43 to detect three detection areas. In this way, one light source can detect a plurality of three detection positions according to the number of divisions, so that one light source can detect a wide detection area.

FIG. 5 shows a reflector 39 composed of a prism or the like.
As an example, a wide-angle detection area can be easily set by setting an arbitrary angle. 6 and 7 show examples of the detection structure of the second and sixth passage detection sensors S2 and S6 arranged at the door position where particularly high detection accuracy is required even in the ticket gate passage. The three projected light beams 64 divided by changing the arrangement positions and the inclination angles of the optical axis changing plates 61 to 63 ...
Are concentrated on the door to ensure reliable detection. In addition, the first to detect the front of the entrance of the ticket gate passage 19
The traffic detection sensor S1 detects the reflected light from the passengers,
Detects that a passerby is approaching.

Therefore, even if baggage or a person's limbs are located at the entrance / exit of the passage, they can be accurately detected, and these sensors S1
-S9 can be combined to accurately detect the moving direction of passersby, and because one light source is divided and used for detection, there is no light beam interference, no optical axis adjustment is required, and one light source is effectively used. Therefore, the cost can be reduced.

FIG. 8 shows a block diagram of a control circuit of the automatic ticket gate. The CPU 81 controls each circuit device according to a program stored in the ROM 82, and the control data is stored in the RAM.
It is readablely stored at 83.

The magnetic ticket processing device 84 includes an insertion opening detection sensor 84a, an insertion opening shutter mechanism 84b, and an insertion opening shutter mechanism 84b between the ticket conveyance paths.
The magnetic head 84c, the ticket pool mechanism 84d, and the ejection opening detection sensor 84e are provided, and the inserted magnetic ticket 13 is processed into magnetic data and ejected to the ejection opening 15.

In this case, since the CPU 81 can open and close the slot 14 by controlling the slot shutter mechanism 84b, the shutter of the slot 14 is temporarily closed to regulate the slot at the time of the ticket processing of the magnetic ticket 13 which is frequently used for the ticket. , A smooth ticket wiping process of the magnetic ticket 13 is performed according to the usage state of the wicket such as continuous wicket / non-continuous wicket.

Further, since the magnetic ticket 13 inserted by the ticket pool mechanism 84d can be temporarily pooled, the magnetic ticket 1
When the use of the ticket of No. 3 is concentrated, the magnetic ticket 13 is temporarily pooled and the release timing of the magnetic ticket 13 is slightly delayed. Passengers who use the ticket will be processed smoothly.

Further, the CPU 81 drives the door opening / closing device 85 based on the judgment result of judging the ticket gate data to open / close the ticket gates 12, 12. At this time, when traffic is restricted due to transmission abnormality, card abnormality, magnetic ticket abnormality, or the like, an alarm sound is emitted by the alarm device 86 to inform the passing passenger that the ticket is not suitable.

Incidentally, the CPU 81 takes correspondence between the passerby and the magnetic ticket 13 or the contactless card 16 prior to the ticket examination processing, and confuses the ticket examination processing with the corresponding relationship even in the continuous ticket examination processing. Instead, it is set so that the ticket can be processed smoothly by taking the correct correspondence.

This is the first for the entire area of the ticket gate passage 19.
~ A large number of detection areas are set by using the ninth traffic detection sensors S1 to S9, and the number of detection areas can detect the following passengers from the entrance to the exit of the ticket gate passage 19, so that the behavior of the passengers Even if there are various types, it is possible to accurately deal with customers and tickets. In particular, since one light source can be divided and the optical axis can be set in any direction to be detected, it is possible to reliably detect the entrance and exit of the passage that requires high detection performance, and it is possible to reliably follow and detect from adults to infants. In accordance with this, the doors can be opened / closed and the safe door control for all the passersby 20 can be performed.

Next, the processing operation of the automatic ticket gate will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. Passengers 2 now
When 0 uses the ticket gate, the first passage detection sensor S1 detects the presence of a customer approaching to enter the ticket passage 19, and the second passage sensor S2 detects that the customer has entered the passage.
The detection is confirmed in S3 (step n1).

At this time, when it is detected that the magnetic ticket 13 or the contactless card 16 used at the ticket gate is used at the entrance of the passage, the CPU 81 determines the type of ticket used (step n2).
), When one magnetic ticket 13 is used, the one insertion is detected by the slot detection sensor 84a, and the suitability of using the ticket with this one magnetic ticket 13 is determined (step n).
3).

Further, when a plurality of magnetic tickets are used, such as a combination of a passenger ticket and a connecting ticket, the slot detection sensor 84a is used.
The CPU 81 detects the insertion of a plurality of magnetic tickets and determines the suitability of using the ticket from the plurality of magnetic tickets 13 ... And the CPU 81 receives the plurality of magnetic tickets 13 and starts the ticket gate data processing (steps n4 to n5).

Furthermore, when the contactless card 16 is used,
The transmission control device 17 communicates with the card 16 in a contactless manner and starts using the ticket gate with the contactless card 16 (step n6).

At the time of using the ticket gate, the CPU 81 reads the ticket data and determines the validity of the ticket use medium (step n7), the CPU 81 determines that the ticket use medium is valid, and the corresponding passenger 20 The passage position is detected by the passage detection sensor. In the vicinity of the passage entrance, it is detected that the third passage detection sensor S3 has moved after the second passage detection sensor S2, and the start confirmation from the passage entrance is confirmed by the confirmation of the seventh passage detection sensor S7. (Step n8).

In accordance with the detection confirmation, the CPU 81 determines that the ticket gate is used smoothly if the ticket use data and the movement of the customer are not abnormal, and allows the next customer to receive the medium (step n9).

Further, in the vicinity of the center of the passage, it is detected that the fourth passage detecting sensor S4 has moved following the third passage detecting sensor S3, and the passage of the vicinity of the center of the passage is confirmed by confirming the detection by the eighth passage detecting sensor S8. It is detected and confirmed (step n10).

Further, in the vicinity of the passage exit, it is detected that the fifth passage detection sensor S5 follows the fourth passage detection sensor S4, and the passage has been confirmed by the eighth passage detection sensor S8. This is detected and confirmed (step n11).

Further, the passerby 20 is the door 12 on the exit side of the passage.
When approaching, the fifth passage detection sensor S5 and then the sixth passage detection sensor S6 are detected to move, and the position of the ticket gate 12 on the exit side of the passage is confirmed by the confirmation of the ninth passage detection sensor S9. The movement is detected and confirmed (step n12).

Immediately before passing through the ticket gate passage 19, the CPU 8
1 emits the inserted magnetic ticket 13, and the guide display 1
The ticket usage guide for the next customer is displayed at 8 and the ticket is switched to the next customer (step n13).

Finally, when the passage to the exit direction is confirmed from the detection information of the sixth passage detection sensor S6 at the end of the passage, it is judged that the use of the ticket gate of one person is completed, and the ticket control of the next customer is switched to (step). n14 to n15).

By the way, immediately after detecting the passerby 20 who has entered the ticket gate passage 19 and when the movement in the backward direction is detected and the detection is finally undetected, it is determined that the passerby 20 retreats and has evacuated. At that time, the medium used at the ticket gate is returned to invalidate the acceptance. In addition, even when the passerby temporarily evacuates from the ticket gate passage 19 or shows irregular behavior such as reconsidering and re-operating the non-contact card 16, each pass detection sensor S1
Since the forward / backward movement can be detected from the detection data of S9 to S9, the movement of the passerby 20 in the ticket passage 19 can be accurately detected and a correspondence with the ticket utilization medium can be taken (steps n16 to n17). ).

If the CPU 81 determines that the ticket-utilizing medium is invalid (steps n18 to n19), it guides the fact that the ticket is invalid on the guidance display 18, and the ticket is regulated by the customer from the ticket passage 19. After confirming the evacuation, it is reset and prepared for the next passenger to use the ticket gate (step n).
20-n22).

When it is determined that the magnetic ticket 13 is invalid due to being forgotten to be inserted, the fact is displayed on the guide display 18 to guide the re-operation (steps n23 to n24), and the re-operation is performed. The CPU 81 executes a ticket processing operation according to the ticket utilizing medium (step n25).

At this time, even if the passerby 20 tries to pass through the ticket gate in an unsuitable state without re-operating, the ticket gate is regulated (step n26), and when the contactless card 16 is judged to be invalid due to communication failure, the same applies. Then, the fact is displayed on the guidance display device 18 to guide the re-operation (step n27).

As described above, since one light source can form a wide detection area, the position and moving direction of baggage or a person moving in a passage can be accurately detected, and one light source is divided and used. Light interference is eliminated due to the configuration,
No optical axis adjustment is required, and the entire ticket gate passage is used as a detection area, and the number of sensors arranged in the entire detection area can be reduced to achieve cost reduction. In particular, since the optical axis can be divided into arbitrary inclination directions so that the entrance and exit of the passage can be detected reliably, regardless of various behaviors of the passerby such as the passerby returning, the correspondence with the passerby can be taken accurately. The position and moving direction of the passerby can always be detected accurately. In addition, one light source can be effectively used to widen the detection area, so if multiple light sources are installed in the entire passage, it can be detected reliably from adults to infants, and the door can be opened / closed accordingly. If operated, safe door control for all passersby is possible.

In the correspondence between the present invention and the configuration of the above-described embodiment, the light source of the present invention is the light projecting element 31 of the embodiment.
Corresponding to the above, similarly, the splitting means includes the slit 34 for splitting the projected light beam, the first to third optical axis changing plates 35 to 37, 61 to.
63, the reflected light corresponds to the light receiving line 42, the detecting means corresponds to the first to third light receiving elements 44 to 46, the object corresponds to the passerby 20, and the judging means corresponds to the CPU 81. Correspondingly, the doors correspond to the ticket gates 12 and 12, the return reflection plates correspond to the first to third reflection plates 39 to 41, and the follow-up detection means are the first to ninth passage detection sensors S1 to S9. However, the present invention is not limited to the configuration of the above-described embodiment.
