Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance / exit management gate apparatus, and relates to an improvement of an entrance / exit management gate apparatus suitable for, for example, an automatic ticket gate at a station.

<< Outline of the Invention >> In the entrance / exit management gate device of the present invention, a plurality of detecting means for detecting a passerby are arranged at intervals along the passage in the device body forming the passage, and the passage by the detecting means on the entrance side is passed. The passenger's luggage that is configured to stop the detection function of the entrance-side detection means from the time when the person is detected until the time when the passage-side detection means is detected by the exit-side detection means It is configured so that it does not detect, etc., and enables accurate counting of passersby.

<< Prior Art and Its Problems >> Conventionally, as an entrance / exit management gate device of this type, a passage for a passerby is formed by the main body of the device, and a detection sensor means composed of a light emitting / receiving element is arranged across the passage. A general configuration is to detect a passing person by shading the passing person.

However, in such a configuration, for example, when a passerby passes the luggage along with the back of the body at the height of the detection means, not only the passerby is detected but also the luggage is detected as another passerby. , There was a problem of miscounting.

<Object of the Invention> The present invention has been made to solve such a conventional drawback, and even if a passerby passes by with luggage or the like back and forth, the luggage is ignored and the passer is accurately identified. It is intended to provide an entrance / exit management gate device that can count.

<< Structure and Effect of the Invention >> In order to achieve such an object, the present invention, in an entrance / exit management gate device for detecting a passerby passing through a passage, is arranged in front and behind along the passage with a space, Two detection means for detecting a passerby passing through the passage;
When the front side detection means detects a passerby, the front side detection means stops the subsequent detection operation, and when the rear side detection means detects the passerby, the front side detection means A detection control unit that causes the detection unit to restart the detection operation.

Therefore, according to this entrance / exit management gate device, after the detection means provided on the front side, for example, the entrance side of the passage detects the passerby, the detection means provided on the rear side, for example, the center of the passage passes. Until the person is detected, the detection function of the detection means on the front side of the passageway is stopped, so even if there is a passer's baggage that continuously passes before and after the passerby,
The baggage and the like will no longer be detected, and the passing person can be accurately counted.

Therefore, the continuous passage of the passerby becomes smooth, and congestion at the time of passage can be eliminated.

<< Description of Examples >> Examples of the present invention will be described below.

1 and 2 are perspective views showing the appearance of an entrance / exit control gate apparatus of the present invention, and FIG. 2 is shown in an exploded manner for convenience.

In the figure, the entry / exit management gate apparatus of the present invention is configured by roughly arranging an entry gate apparatus 1 and a gate panel apparatus 3 in parallel with each other at an interval. A passage 5 is formed between them.

In the upper part of the entrance side of the case 7 of the introductory gate apparatus 1,
A card insertion slot 9 for inserting a card such as a ticket or a commuter pass in which predetermined information is stored in advance is arranged, and a card reader unit 11 for reading the contents of the inserted card is continuous to the card insertion slot 9. The card take-out port 13 is connected to the card reader unit 11 so that the read cards can be taken out along the passage 5.

On the exit side of the entrance gate device 1, a door portion 15 for opening and closing the passage 5 is openably and closably attached to the housing 7, and the passage 5 can be opened and closed by a predetermined control signal.

In the case 7 of the introductory gate apparatus 1, as shown in FIG. 2A, an entrance side light emitting part 17, a center light emitting part 19 and an exit side light emitting part 21 gate light at an entrance side, a central part and an exit side, respectively. The panel device 3 is arranged to fire.

Since the exit side light emitting section 21 is arranged inside the door section housing section of the housing 7, it is not visible in the figure.

On the other hand, in the gate panel device 3, as shown in FIG. 2B, the entrance side light emitting section 17, the central light emitting section 19 and the exit side light emitting section are provided in a portion of the housing 23 facing the passage 5. An inlet side light receiving section 25, a central light receiving section 27, and an outlet side light receiving section 29 that receive the light from 21 are arranged.

Then, at the entrance side, the central portion and the exit side, the entrance side light emitting / receiving sections 17, 25, the center light emitting / receiving sections 19, 27, the exit side light receiving / receiving section 2
The passerby is detected when the passerby passes through between 1 and 29 and blocks light.

Moreover, each of the entrance side light emitting / receiving parts 17, 25, the central light emitting / receiving parts 19, 27, and the exit side light emitting / receiving parts 21, 29 is composed of two light emitting elements and two light receiving elements facing each other in the passage direction. And substantially has two detection means.

Therefore, the passing direction of the passerby can be determined by the light-shielding order of the passerby. Furthermore, the light emitting / receiving unit on the entrance side
Numerals 17 and 25 form the detection sensors I ₁ and I ₂ to form an entrance side detection section C as a front side detection means.
Reference numeral 7 is a central detection portion D as a detection means on the rear side which forms detection sensors I ₂ and E ₃ , and further, an exit side light emitting and receiving portion 2
Numerals 1 and 29 form detection sensors E ₂ and I ₂ and serve as an outlet side detection portion E (see FIG. 3).

As shown in FIG. 3, the inlet side detection unit C, the central detection unit D, and the outlet side detection unit E are connected to a CPU 33 functioning as a detection control unit or the like via an interface 31.

The CPU 33 is connected to the host controller 37, the card reader unit 11, and the door unit 15 through the interface 35, and has a function of executing a predetermined process described below using the RAM 41 according to a program stored in the ROM 39 in advance. Besides, for example, the door portion 15 is opened and closed based on the information from the card reader portion 11.

The CPU 33 has an entrance counter and an exit counter, and has a function of turning on / off the entrance sensor disregard flag according to the detection output of the entrance side detection unit C and the central detection unit D.

The input counter counts the number of passers-by on the entrance side from the center of the device, and the exit counter counts the number of passers-by on the exit side from the center of the device.
Further, the entrance sensor disregard flag is controlled so that the entrance side detection unit C ignores the detection of a passerby while the flag is ON.

In addition, the operation of the entrance / exit management gate apparatus of the present invention will be clarified by the following processing procedure.

The control means shown in FIG. 3 is housed in the entrance gate device 1 described above, for example.

FIG. 4 shows the operation of the entrance / exit management gate apparatus of the present invention, particularly the operation of the control means centering on the CPU 33.

When the entrance / exit control gate device operates and a card is inserted in step 100, the card is determined in step 101, and if it is NO because it is an inappropriate card, the door part
The processing procedure returns to step 100 while the path 15 is still closed.

When an appropriate card is inserted and step 101 becomes YES, the door 15 is opened in step 102, the entrance counter and exit counter in the CPU 33 are set to "0" in the next step 103, and the entrance sensor is ignored. The flag is set to OFF and the routine proceeds to step 104.

In step 104, it is determined whether or not a passerby is detected in the entrance side detection unit C, and if NO, step 105
Then, it is determined whether or not a passerby is detected by the central detecting section D.

In the case of NO, it is further determined in step 106 whether or not the exit side detection unit E has detected. Step
If 106 is NO, the process returns to step 104.

That is, in any of the entrance side detection unit C, the central detection unit D, and the exit side detection unit E, steps are performed until detection is performed.
Repeat steps 104 through 106.

The passerby invades with luggage behind and step 104 is Y
When it becomes ES, the entrance sensor ignore flag is set to O in step 107.
It is determined whether or not N, and if YES, step 104
If NO, in step 108, "1" is added to the entrance counter.

Next, at step 109, the entrance sensor ignore flag is set to ON, and the process returns to step 104.

That is, when a passerby intrudes with luggage behind the body and only the passerby is detected, the entrance sensor ignore flag is set to OF.
Since it is F, the entrance counter is set to "1", the entrance sensor ignore flag is set to ON, the operation of the entrance side detector C is stopped, and the operations of steps 104 to 106 are repeated.

Then, the parcel passes through the entrance-side detection unit C, and the step 10
Even if 4 is YES, step 107 is YES and it is not detected as an intruder of a passerby.

When the passerby passes through the central detection unit D and step 105 becomes YES, it is judged at step 110 whether or not the entrance counter is "0", and if YES, the process returns to step 104 and NO.
In the case of the
While "1" is added, "1" is added to the exit counter. In the following step 112, the entrance sensor ignore flag is set to OFF, and the process returns to step 104.

That is, when the passing detector is detected by the central detector D, the entrance sensor ignore flag is set to OFF.
The operation of the entrance-side detector C is started. Moreover, although the parcel passes through the central detection unit D, since the entrance counter is "0", the entrance / exit counter and the entrance sensor ignore flag are not changed.

When a passerby is detected by the exit side detection unit E, step 106 returns Y.
When it becomes ES, it is determined in step 113 whether or not the output counter is "0", and the passerby has finished passing through the exit side detection unit E.
If YES, the process ends, and if the passerby does not complete the pass and is NO, "-1" is added to the output counter in step 114 and the process proceeds to step 115.

In step 115, for example, a 5-second timer is started,
In step 116, it is determined whether or not the timer has timed out. If NO, the process returns to step 116 to continue counting, and if YES, the door portion 15 ends for the time being in step 117.

Therefore, the door portion 15 closes the passage 5 five seconds after the passerby passes through the passage 5, and the door portion 15 is closed during passage.
Fifteen is designed not to hit passersby or passersby luggage.

As described above, in the entrance / exit management gate device of the present invention, even if a passerby carrying a baggage passes, the baggage is regarded as a part of the passerby and ignored, and the correct number of passages can be detected. .
