Description

Security gate system

This invention relates to a security gate system.

In the security gate system, the reader receives radio waves from the tag possessed by the user. Based on the radio wave, the reader transmits identification information and the like to the controller. Based on the identification information, the controller specifies the user. If the user is authenticated, admission from the security gate is permitted. If the user is not authenticated, entry from the security gate is not permitted (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 7-21421 Japanese Unexamined Patent Publication No. 2010-176223 Japanese Unexamined Patent Publication No. 2000-331202 Japanese Unexamined Patent Publication No. 2004-297292

However, radio waves from tags and radio waves from mobile phones may interfere with each other. In this case, the reader cannot correctly recognize the identification information and the like. As a result, even a user who should be authenticated may not be authenticated. In this case, the user must authenticate again. That is, the user must reenter the security gate. As a result, the security gate becomes crowded.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a security gate system that can alleviate congestion of security gates.

The security gate system according to the present invention outputs a first radio wave that forms an authentication area at the entrance of the gate, and a second radio wave that forms a pre-authentication area on the front side of the authentication area with respect to the entrance of the gate. And a main authentication that receives the identification information from the detection unit and performs an authentication process on the identification information when the detection unit receives the identification information by radio waves from a tag in the authentication area. A pre-authentication unit that performs an authentication process on the simple information when the detection unit receives simple information having a smaller information amount than identification information by radio waves from a tag in the pre-authentication area, and the pre-authentication A notification unit that notifies the tag that transmitted the simple information of whether or not the gate can pass based on the authentication result of the simple information by the unit.

The security gate system according to the present invention outputs a radio wave that forms an authentication area at the gate entrance, and outputs a radio wave that forms a pre-authentication area on the near side of the authentication area to the gate entrance. And when the detection unit receives identification information by radio waves from a tag in the authentication area, the authentication unit receives the identification information from the detection unit and performs an authentication process on the identification information, and When the detection unit receives simple information having an information amount smaller than the identification information by radio waves from the tag in the pre-authentication area, the pre-authentication unit that performs authentication processing on the simple information and the pre-authentication unit A control unit that moves a detection area of a sensor provided in the gate in a direction away from the entrance of the gate.

In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a security gate system according to Embodiment 1 of the present invention.

As shown in FIG. 1, the security gate 1 includes a pair of

casings

1a and 1b. A photoelectric post 1 c is provided on one side of the entrance of the security gate 1. An intrusion sensor 2 is provided in the center of the casing 1a in the longitudinal direction. For example, the intrusion sensor 2 is an infrared sensor. The intrusion sensor 2 has an intrusion detection area 2a. Intrusion sensor 2 is formed to be movable in the longitudinal direction of housing 1a.

An entrance reader 3 is provided in front of and above the security gate 1. The ingress reader 3 outputs first and second radio waves having different intensities from one HF (hands-free) antenna (not shown). The ID authentication area 3a is formed by the first radio wave. The ID authentication area 3a is formed at the entrance of the security gate 1. The pre-authentication area 3b is formed by the second radio wave. The pre-authentication area 3b is formed so as to cover the ID authentication area 3a. That is, the pre-authentication area 3b extends to the near side of the entrance of the security gate 1 with respect to the ID authentication area 3a.

A controller 4 is connected to the intrusion sensor 2 and the incoming reader 3. The controller 4 has a function of controlling the intrusion sensor 2 and the incoming reader 3.

User possesses tag 5 using RFID. The tag 5 stores ID information (identification information) and simple information. The ID information is information unique to the user who possesses the tag 5. The simple information includes an information amount that is smaller than the information amount of the ID information. For example, the simple information includes expiration date information. The expiration date information consists of information corresponding to the expiration date of the tag 5.

Next, the operation of the security gate system will be described with reference to FIG.
FIG. 2 is a flowchart for explaining the operation of the security gate system according to the first embodiment of the present invention.

In step S1, the user who has the tag 5 enters the pre-authentication area 3b from the front side of the security gate 1. At this time, the incoming reader 3 receives a radio wave from the tag 5 as a detection unit. Then, it progresses to step S2 and the entrance side reader | leader 3 performs the process of the pre-authentication with respect to simple information as a pre-authentication part.

For example, the ingress reader 3 determines whether the radio wave from the tag 5 interferes with the radio waves of other devices based on the received expiration date information or the like as an interference power determination unit. In other words, the ingress reader 3 determines whether or not communication that is equal to or lower than a preset communication error rate has been established. For example, the ingress reader 3 determines whether or not the expiration date of the tag 5 has expired based on the received expiration date information.

At this time, the ingress reader 3 identifies the number of users in the pre-authentication area 3b and grasps the degree of congestion of the security gate 1. When there are many users, the incoming reader 3 determines that the possibility of interference from the tag 5 is high. In this case, the process proceeds to step S3. If the expiration date of the tag 5 has expired, the process proceeds to step S3.

In step S3, the incoming reader 3 expands the pre-authentication area 3b. In this case, the intensity of the second radio wave increases at the same position. As a result, radio wave interference of the tag 5 is suppressed. Then, it returns to step S1.

If there is no problem in checking the simple information in the pre-authentication in step S2, the process proceeds to step S4. In step S4, the incoming reader 3 stores the ID information of the tag 5. Thereafter, the ingress reader 3 transmits, as a notification unit, a radio wave for notifying the user that pre-authentication is not a problem toward the tag 5. Based on the radio wave, the tag 5 vibrates or makes a sound.

Thereafter, the process proceeds to step S5, and the user enters the ID authentication area 3a. At this time, the incoming reader 3 receives the radio wave from the tag 5 again. Then, it progresses to step S6 and the entrance side reader | leader 3 checks a pre-authentication result. Thereafter, the incoming reader 3 determines whether or not the ID information based on the radio wave matches the ID information stored at the time of pre-authentication.

If the ID information does not match in step S6, the process returns to step S1. In this case, when the user proceeds through the security gate 1, the intrusion sensor 2 detects the unauthorized intrusion of the user.

If the ID information matches in step S6, the process proceeds to step S7. In step S7, the incoming reader 3 determines that it is not an unauthorized intrusion by the user. In this case, the controller 4 moves the intrusion sensor 2 in a direction away from the entrance of the security gate 1 as a control unit.

Thereafter, the process proceeds to step S8, where ID authentication is performed. Specifically, the controller 4 determines, as the authentication unit, whether the ID information matches the ID information stored in advance.

If the ID information matches in step S8, the process proceeds to step S9. In step S9, the user is permitted to enter from the security gate 1. That is, the controller 4 determines that the user normally passes through the security gate 1. In this case, the controller 4 ignores the detection of the user by the intrusion sensor 2 or stops the operation of the intrusion sensor 2.

If the ID information does not match in step S8, the process proceeds to step S10. In step S10, the user is not permitted to enter from the security gate 1. That is, the controller 4 determines that the user enters the security gate 1 illegally. In this case, when the user proceeds through the security gate 1, the intrusion sensor 2 detects the unauthorized intrusion of the user.

According to Embodiment 1 described above, pre-authentication is performed before ID authentication. For this reason, when there is a problem in pre-authentication, a user who is assumed not to be authenticated during ID authentication can be prevented from entering the ID authentication area 3a. That is, the number of authentication failures in ID authentication can be reduced. As a result, the congestion of the security gate 1 can be reduced in the morning or the like.

In addition, when authenticated by pre-authentication, the intrusion sensor 2 moves away from the entrance of the security gate 1. As a result, the intrusion detection area 2a moves to the back side of the security gate 1. For this reason, it can prevent being detected by the intrusion sensor 2 during ID authentication. As a result, it is possible to prevent a user to be authenticated from being authenticated.

In this case, the security gate 1 may be a gate that can also use an IC card. According to the gate, it is possible to prevent the user who has been authenticated by the IC card from being illegally intruded during the ID authentication of the user who possesses the tag 5.

Note that the frequency of the first radio wave and the frequency of the second radio wave may be different from each other. Further, the first radio wave and the second radio wave may be output alternately. In these cases, interference between the first radio wave and the second radio wave can be prevented.

Further, it may be notified to the user by lighting the photoelectric post 1c that it has been authenticated by the pre-authentication.

Also, a plurality of intrusion sensors 2 may be arranged in the longitudinal direction of the security gate 1. In this case, in normal times, the intrusion sensor 2 on the front side of the security gate 1 may detect the unauthorized intrusion. What is necessary is just to detect an unauthorized intrusion with the intrusion sensor 2 in the back | inner side of the security gate 1 when it authenticates by pre-authentication. Also in this case, the intrusion sensor 2 can be prevented from being detected during ID authentication. As a result, it is possible to prevent a user to be authenticated from being authenticated.

Also, the tag 5 may be notified that there is a problem in pre-authentication without notifying the tag 5 that there is no problem in pre-authentication. In this case, when the tag 5 vibrates or makes a sound, the user can be made aware of the abnormality.

Embodiment 2. FIG.
FIG. 3 is a configuration diagram of the security gate system according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and description is abbreviate | omitted.

The ingress reader 3 of the first embodiment outputs the first radio wave and the second radio wave so that the ID authentication area 3a and the pre-authentication area 3b overlap. On the other hand, the ingress reader 3 according to the second embodiment outputs the first radio wave and the second radio wave so that the ID authentication area 3a and the pre-authentication area 3b do not overlap.

Specifically, the ingress reader 3 includes a first antenna 6a and a plurality of second antennas 6b. The first antenna 6a outputs a first radio wave. Each of the second antennas 6b outputs a second radio wave. At this time, adjacent pre-authentication areas 3b are formed so as to contact each other. As a result, the ID authentication area 3a is covered with a plurality of pre-authentication areas 3b from the front side of the entrance of the security gate 1.

According to the second embodiment described above, the ID authentication area 3a and the pre-authentication area 3b do not overlap. For this reason, even if the first radio wave and the second radio wave are simultaneously output at the same frequency, interference between the first radio wave and the second radio wave can be prevented.

As described above, the security gate system according to the present invention can be used for a system that alleviates congestion of security gates.
