Abstract

PROBLEM TO BE SOLVED: To provide a management system for entering and leaving persons capable of accurately managing entrance and exit to/from a facility by combining an RFID with an intruder detector such as an infrared sensor even in the case authorized persons and unauthorized persons are present. SOLUTION: An RFID tag 4 is attached to an entering/leaving person. RFID unidirectional antennas 21 and 22, tag receivers 31 and 32 and intruder detectors 11 and 12 are installed at an entrance. The intruder detectors 11 and 12 are released or the detection of the intruder detectors 11 and 12 is nullified by receiving the passable ID of the tag 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance / exit management system, and more particularly to an RFID (Radio Frequency Ide) in a place without a door such as outdoors.
nifation (radio wave method recognition). In this specification, it is referred to as “RFID”. ) And an intrusion detector, such as an infrared sensor, by which an entrance / exit of a permitted person and a non-permitted person can be accurately managed.

[0002]

2. Description of the Related Art Conventionally, an entry / exit management system combines a contact-type or non-contact-type IC tag, and when an authorized person enters, confirms the ID of the IC tag and unlocks the door. Or to open and close automatic doors. In the outdoors, an intrusion detector such as an infrared sensor is used to indiscriminately detect an intruder and issue an alarm.

[0003]

However, in the above-mentioned conventional entrance / exit management system using an IC tag, it is not possible to identify a person passing through the gate outdoors or in a place without a door. There was a problem that you can not do. In addition, in the method of installing a detector such as an infrared sensor, in order to indiscriminately detect persons involved in the facility and outsiders, when the persons concerned pass, measures such as canceling the detector each time are taken. Is required, and there is a problem that the operation is troublesome.

The present invention has been made in view of the problems of the above-mentioned conventional entrance / exit management system, by combining an RFID and an intrusion detector such as an infrared sensor, etc., so that even authorized persons and non-authorized persons are mixed. It is another object of the present invention to provide a management system for a person who can enter and leave the facility accurately.

[0005]

In order to achieve the above object, a system for managing visitors according to the present invention is provided.
In addition to providing FID tags, RFID unidirectional antennas, tag receivers and intrusion detectors are installed at the entrance and exit, and the intrusion detector is released or the intrusion detector is detected by the received pass permission ID of the tag. It is characterized in that it is invalidated.

[0006] This entrance / exit management system assigns an RFID tag to the entrance / exit and also adds an RFID tag to the entrance / exit.
A unidirectional antenna, a tag receiver and an intrusion detector of D are arranged, and the intrusion detector is canceled or the detection of the intrusion detector is canceled by the received permission ID of the tag. When a person with an RFID tag is automatically permitted to enter or leave, if a person with an RFID tag without a pass permission ID or a person without an RFID tag attempts to enter or leave, an intrusion detector is activated, The entry / exit can be automatically prevented by a warning, closing a gate, photographing with a camera, or the like.

In this case, a pair of RFID unidirectional antennas and a tag receiver are arranged at the entrance and exit, and the detection range of each antenna is set so as to be shifted before and after the entrance and exit, and the order of reception of the tag receiver is set. Thus, entry and exit can be determined.

Thus, it is possible to manage entry and exit of a person only when entering or leaving.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an entrance / exit management system according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of a system for managing visitors according to the present invention. The entrance / exit management system assigns long-distance RFID tags 4 to entrances and exits, and RFID unidirectional antennas 21 and 22 and long-distance tag receivers 31 at entrances G of facilities and the like. , 32 and intrusion detectors 11, 12 such as infrared sensors, etc., and the intrusion detectors 11, 1,
2 is canceled or the detection of the intrusion detectors 11 and 12 is invalidated.

In the illustrated embodiment, an entrance G is provided between poles P1 and P2 which are erected at predetermined intervals, and an intrusion detector, such as an infrared sensor, for detecting intrusion or passage of the poles P1 and P2. 11 and 12 are arranged facing each other.

The poles P1 and P2 have a pair of RFID unidirectional antennas 21 and 22 and a tag receiver 3 respectively.
1 and 32, and each antenna 21, 2
The two detection ranges are set so as to be shifted before and after the entrance G, so that entry and exit can be determined based on the reception order of the tag receivers 31 and 32. In addition, RFI
The tag receivers 31 and 32 to which the D unidirectional antennas 21 and 22 are connected, respectively, are connected to a common receiver station 5.
It is connected to the.

Next, the operation of the entrance / exit management system will be described. When the person wearing the RFID tag 4 approaches the entrance G, the transmission from the RFID tag 4 is received by one of the unidirectional antennas 21 and 22. In this case, since the reception range of the RFID tag 4 is limited so as to be shifted back and forth,
The approach direction can be specified from the tag receivers 1 and 22 and the tag receivers 31 and 32. The unidirectional antennas 21 and 22
The ID (data) of the RFID tag received at is transmitted to the receiver station 5 via the tag receivers 31 and 32 connected to the unidirectional antenna. The receiver station 5 determines the direction of passage of the RFID tag 4 and identifies the ID of the RFID tag 4 to determine whether or not to permit the passage.
1 or 12 is canceled or the detection of the intrusion detectors 11 and 12 is invalidated, and the passage of the entrance G is permitted.

[0014] Further, if the entrance and exit does not have the RFID tag 4, or if it is determined that the ID of the RFID tag 4 is not permitted to pass, the intrusion detector is activated, and a warning is issued, or the entrance G The entrance and exit are automatically blocked by blocking the intruder or photographing the intruder with a camera.

In this case, a pair of RFID antennas 21,
By setting the detection range of 22 to be shifted before and after the entrance, and distinguishing entry and exit based on the order of reception of the tag receivers 31 and 32, it is possible to manage entry and exit of the person only at the time of entry or exit. it can.

[0016]

According to the entrance / exit management system of the present invention, an RFID tag is given to an entrance / exit and an RFID unidirectional antenna, a tag receiver and an intrusion detector are arranged at the entrance and exit. Since the intrusion detector is canceled or the detection of the intrusion detector is canceled by the received permission ID of the tag, the entry / exit of the person having the RFID tag of the permission ID is automatically permitted and the permission is given. If a person with an RFID tag without an ID or a person without an RFID tag attempts to enter or exit, the intrusion detector will be activated, and the entry and exit will be automatically performed by an alarm, closing the gate, shooting with a camera, etc. Can be blocked.

In addition, a pair of RFID unidirectional antennas and a tag receiver are disposed at the entrance and exit, and the detection ranges of the antennas are set so as to be shifted before and after the entrance and exit, and the entrance is performed in the order of reception by the tag receiver. And exit can be managed only at the time of entry or exit.
