Abstract

PROBLEM TO BE SOLVED: To surely discriminate and judge the passing priority order of passengers entering nearly simultaneously, and securely inform a passenger entering from the opposite side of the entry prohibition, in a noncontact card type gate device for a bidirectional passage. SOLUTION: When a passenger carrying an admission noncontact card 1a approaches a bidirectional gate device 2, a controlling means 6 receives and detects a radio wave emitted from the admission uncontact card 1a via an entrance directional antenna 3a, and the exit directional passage prohibition lamp 5b on the side opposite to the side where this radio wave is detected is turned on. By this operation, since the entry prohibition is securely informed to the passenger who would enter from the exit direction of the gate, the collision of the passengers in the way of passage can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate device for permitting / prohibiting traffic by wireless communication with a contactless card.

[0002]

2. Description of the Related Art Conventionally, in a gate device using a non-contact card such as an IC card, when a pedestrian carrying the card approaches the gate, the card data is read via an antenna installed at the gate to determine whether or not the pass is possible. Open and close doors such as the flapper installed in the gate passage to allow traffic
Prohibition. As such a non-contact card type gate device, a one-way one-way gate device is known.

On the other hand, in a gate device capable of two-way traffic that also serves as entrance and exit, a contact card type gate device is used in which a passerby passes a magnetic card or the like into a card insertion slot of the gate device. . In this gate device, which side of the entrance or exit the card was inserted into is detected by an optical sensor or the like at the time of card insertion, so that cards of passers-by entering the gate from the opposite side are not accepted. The opposite side of the card slot is closed with a shutter.

[0004]

The conventional contactless card type gate device has the following problems. That is, when a conventional non-contact card type gate device is used as a two-way gate device for both entrance and exit, if a pedestrian enters from both sides of the gate almost at the same time, there is a risk of collision in the middle of the passage.

[0005] The cause of this inconvenience is that in the conventional contactless card type gate device, the priority is given to the passage of the passerby carrying the communication-completed card after the communication between the card and the gate is established. This is because it is difficult to coordinate the control time and the communication time for simultaneous ingress from the vehicle, and control such as opening and closing the flapper cannot be made in time. In addition, even if an attempt is made to detect a passerby card that has entered the gate earlier to eliminate the above-mentioned inconvenience, the contactless card type gate device does not
For example, since the card passes such as a commuter pass in a pocket, unlike a contact card type gate device, the approach of the card itself cannot be reliably detected by an optical sensor or the like.

Further, since the non-contact card type gate device does not have a card insertion slot, there is no means for contact card type which blocks the card insertion slot and prohibits card acceptance and notifies entry prohibition. Not applicable. For this reason, a passerby entering from both sides of the gate almost simultaneously does not know whether or not the card carried by him / her has been accepted first, so that both enter directly and may collide in the middle of the passage.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a non-contact card type two-way traffic gate device, in which a traffic priority order of passers entering at almost the same time is surely identified and determined, and entry to passers from the opposite side is prohibited. Is to be surely notified.

[0008]

A gate device according to a first aspect of the present invention is a two-way traffic gate device for controlling traffic by wireless communication with a card carried by a pedestrian. And a sensing means for sensing a radio wave from the card via a communication antenna, and a notification means for notifying entry prohibition installed at both sides of the passage, and transmitting the radio wave first detected by the sensing means. The notification means provided at the entrance opposite to the entrance of the passerby carrying a notification of entry prohibition.

As a result, when the gate first detects the radio wave from the card, the traffic control is started, and the ban is notified to the pedestrian from the opposite side. The traffic priority order of the passer-by is definitely identified and determined, and the passer-by from the opposite side is securely notified of entry prohibition. A gate device according to a second aspect of the present invention is the gate device according to the first aspect, wherein the notification unit is at least one of a lamp lighting, a lamp blinking, an identification display, and an audio output.

[0010] Thus, a passerby entering from the opposite side is reliably notified that entry is prohibited. Invention 3
In the gate device according to the first aspect of the present invention, in the gate device according to the first aspect, the installation location of the notification unit is a communication antenna unit at the entrance on both sides of the passage or in the vicinity thereof. Accordingly, the entry prohibition is notified at a place where the passerby can easily notice, so that the entry prohibition is more reliably notified.

[0011]

FIG. 1 is a block diagram showing an embodiment of the present invention. The gate device according to the present invention includes an attendant non-contact card 1a carried by an attendant, an exit contactless card 1b carried by an exit person, and a two-way gate device 2. Here, the bidirectional gate device 2 is a pair of gates having entrances and exits and facing each other across a passage. The contactless card is a portable card or tag such as an IC card that can transmit and receive data wirelessly.

The following devices are mounted on the bidirectional gate device 2. An entry direction antenna 3a for wireless communication with the contactless card 1a carried by the visitor, and an exit direction antenna 3 for wireless communication with the contactless card 1b carried by the exit person.
b, a storage means 4 composed of a RAM or a ROM for storing various control data, an entry direction no-going lamp 5a and an exit direction no-going lamp 5b for notifying passers-by of no entry from the entrance side of the gate, and , A control means 6 including a CPU connected to the above-described devices and controlling the entire gate.

FIG. 2 is a flowchart showing the main operation of the gate device according to the present invention. The operation will be described with reference to FIG. When the visitor carries the contactless card 1a and approaches the entrance of the bidirectional gate device 2, the contactless card 1a stands by to receive a carrier (radio wave) transmitted from the gate (step S10). Detecting the carrier transmitted from the entrance direction antenna 3a (branch Y),
The predetermined data such as the ID stored in the card is transmitted (step S11).

The bidirectional gate device 2 is also waiting for carrier detection from the card (step S20), and when the radio wave from the non-contact card 1a is received via the entry direction antenna 3a (branch Y). Then, the exit direction no-prohibition lamp 5b on the opposite side to the detection of the radio wave is turned on (step S21). With this operation, it is possible to notify a passerby entering from the exit direction of the gate that entry of the traffic is prohibited.

In addition, as a notification method of the traffic prohibition, a lamp is turned on or flashing, or an indicator such as an LED (light emitting diode) or a liquid crystal display is installed in an antenna installation portion or a place where a pedestrian can easily notice. "X" or "-"
For example, identification and display may be performed using symbols, illustrations, and characters, and announcements and warnings may be output as audio. Next, the control means 6 communicates with the visitor non-contact card 1a via the entrance direction antenna 3a (step S22), and judges whether or not the vehicle can pass based on the received card data (step S2).
3). If the passage is possible (branch Y), the entrance flapper is opened (step S24), and after the passage of the passerby or after a predetermined time (step S25, branch Y), the entrance flapper is closed (step S26). Further, the exit direction no-go lamp 5b, which indicates no-go traffic, is turned off (step S2).
7) Return to step S20, and wait for reception of a carrier from the card on both sides of entry and exit (steps S20, S20).
28).

In the above description, the case where the visitor non-contact card 1a approaches the gate has been described, but the operation is the same for the exit person non-contact card 1b. That is, when the exited non-contact card 1b approaches the gate, the entrance direction no-going lamp 5a is turned on to display the no-going to the attendant side (steps S28 and S29), and the traffic operation is performed in the same manner as described above. (From step S30 to S
34), the entrance direction no-go lamp 5a is turned off (step S27), and the process returns to step S20.

According to the above operation, in the contactless card type two-way traffic gate device, even if a pedestrian enters the gate almost at the same time, the priority order of the traffic can be reliably identified and determined, and the traffic from the opposite side can be determined. It is possible to reliably notify a person that entry is prohibited.

[0018]

According to the present invention, the traffic control is started not at the time of the conventional communication between the card and the gate but at the time when the gate first receives the radio wave from the card, and the traffic from the opposite side is started. Therefore, even if a non-contact card type two-way gate device is used, the priority order of traffic can be reliably determined, and a person coming from the opposite side of the gate can be reliably notified of the prohibited traffic. As a result, even if a passerby enters from both sides of the gate almost at the same time, it is known whether or not his or her card has been accepted first, and the passerby will wait for entry, so there is a possibility that it will be hit in the middle of the passage. Disappears.

Further, if the notification means is at least one of lamp lighting, lamp blinking, identification display, and voice output, a conventional contact card type is used to notify the entry inhibition by covering the card insertion slot. In a manner similar to the method described above, it is possible to reliably notify a passerby that entry is prohibited. Furthermore, if the notification means is installed at the communication antenna section or in the vicinity of the entry section on both sides of the passage, the passerby always approaches the card when passing, so that the entry prohibition notification can be more reliably notified.
