Description

The present invention relates to an admission management system using an IC tag.

Various entrance / exit management systems have been proposed to prevent unauthorized persons from entering the limited area and to grasp the number of personnel existing in the limited area. As shown in Patent Documents 1 and 2, an IC card having an IC tag with an ID is generally used for the entrance / exit management system. When an employee or the like who has the authority to enter the limited area tries to enter the limited area, the IC card reader attached to the door or the gate is made to read his / her own IC card. The entrance / exit management system reads the ID recorded on the IC tag of the IC card, and if it can be confirmed that the ID is permitted to enter the limited area, the door or gate is temporarily unlocked and opened. To allow employees to enter.

In addition, IC tags other than the card type have also been proposed. Patent Document 3 proposes that an IC tag is attached to a cloth product including clothing and the authentication is completed by the clothing. Further, it is proposed in Patent Document 4 that an IC tag is attached to a vehicle such as a forklift to control the entrance of the vehicle.

There are two types of IC tags: an active type that has a battery and transmits radio waves, and a passive type that does not have a battery and drives according to the radio waves from the reader. When attaching an IC tag to a card or clothes, a passive type is basically used. Radio waves in the HF band and UHF band are mainly used to read passive IC tags. In the HF band, a short wave of 13.56 MHz is mainly used, and it is read at a close distance of about 10 cm, which is a so-called touch type. Since the target person to be authenticated needs to perform touch operation, it is suitable for a system in a situation where an individual should be authorized. In the UHF band, ultra-high frequencies of around 900 MHz are mainly used and can be read at a distance of about several meters, so that it is effective for applications such as reading while passing through without performing a touch operation. Since it can be passed hands-free, it is also suitable for systems in situations such as checking each vehicle.

Japanese Patent No. 5251283 Japanese Patent No. 5681544 Japanese Unexamined Patent Publication No. 2008-15682 Japanese Unexamined Patent Publication No. 2016-066168

However, since the UHF band IC tag and the HF band IC tag use different frequency bands, these IC tags cannot be used together, and the management system using the UHF band IC tag and the HF band IC tag cannot be used together. There was no choice but to build it separately from the management system by. That is, a simple type of reader can be configured such that one door can be passed by either an HF band IC tag or a UHF band IC tag, or one door can be passed by only one band IC tag. It was not possible to do this, and two authentication systems corresponding to each band had to be introduced.

Therefore, the present invention makes it possible to use both UHF band IC tags and HF band IC tags in one admission management system, and to construct an environment in which these IC tags can be used together at low cost. The purpose.

Flowchart when an authorized person enters a limited area

Hereinafter, the present invention will be specifically described. The present invention is an admission management system that manages admission to a limited area, and a method for manufacturing the same.

An example of the first embodiment of the entrance management system according to the present invention is shown in FIG. The admission management program of the admission management device 11 constituting the present invention manages the opening and closing of the gate 15 that restricts admission to the limited section 13 that only authorized persons can enter. The admission management device 11 does not have to be a single server as hardware, and may be composed of a plurality of servers to realize the following functions. In addition, although authorized persons are collectively referred to as authorized persons here for convenience, the actual operation target of admission management is not limited to natural persons, and vehicles and other articles may be authorized. In that case, a person who owns other goods or boardes other goods will be temporarily able to enter.

Each of the above-mentioned authorized persons is given a unique identification ID as an identification code. In actual operation, the authorized person is distributed an IC tag recording the given identification ID. The distribution form of this IC tag is not particularly limited, but when the above-mentioned authorized person is a natural person, it is necessary to have a size that can be carried, and a commonly used card-type identification card can be used in the present invention as well. it can. For example, there is a name tag type identification card that is hung from the neck. Further, the IC tag may be loaded in the clothes and distributed so that it can be held over the gate reader 16 described later. Further, it may be attached to a vehicle traveling in the limited section 13 such as a forklift or a cart and distributed.

As the gate 15, a door having an electronic lock (door gate 15a) is shown in FIG. However, the actual form is not limited to this. For example, it may be an automatic ticket gate type opening / closing door, a revolving door, or an elevator or seat shutter (15b) that operates only under permitted conditions. The limited section 13 may be a room, a specific area of the building, a specific floor of the building, or the facility itself, and is not particularly limited. Further, the designated limited section 13 does not have to be one, and may be a plurality of places. Further, when a plurality of limited sections 13 exist, the persons who have the admission authority may be different for each limited section 13.

Regardless of the embodiment, the gate 15 (15a, 15b) is provided with a gate reader 16 that controls opening and closing according to the entrance authority corresponding to the identification ID recorded on the IC tag 14 (14a, 14b). Here, the identification ID received by the gate reader 16 is managed in the authority table 22 of the entrance management device 11, and is uniquely determined in one system. Further, as the IC tag for which the identification ID is recorded in this system, two types of the HF band IC tag 14a and the UHF band IC tag 14b are used in combination.

In the case of the HF band, short-range wireless communication according to ISO15693 can be used. Authentication is performed by manually bringing the IC tag close to the gate reader 16 to a short distance of about 10 cm or less. In the case of the UHF band, it can recognize up to a distance of about 1 meter. In that range, the frequency is not particularly limited, and any standard can be selected and used.

For security reasons, it is preferable that the gate reader 16 is arranged at a position close to the gate 15. If the gate 15 is a door having an electronic lock (door gate 15a), it is preferably on the wall surface next to the door. If the gate 15 is a shutter type such as a sheet shutter 15b, it is preferable that the gate 15 is provided on a wall surface or the like near the shutter. If the gate 15 is an automatic ticket gate type opening / closing door, it may be provided on the upper surface or side surface of both side portions of the automatic ticket gate type. However, as will be described later, when the seat shutter 15b that allows passage only by the UHF band IC tag 14b is set, the gate reader 16 itself does not have to be in contact with a normal user, so that the gate reader 16 itself does not have to be in contact with a normal user. It may be installed.

The admission management device 11 may have an authorized person table 21 for recording the above identification ID. In addition to the identification ID, the authority table 21 may have specific information such as the name and address of an employee or the like to which each identification ID is assigned. In addition, the contents may be shared or diverted from the personnel management database used in other operations. Further, the content may be shared or diverted from the database of the article to be the authority.

The entrance management device 11 may have an authority table 22 for recording the entrance authority to the limited section 13 for the identification ID. When there are a plurality of limited sections 13, admission authority may be given to the above-mentioned identification ID that is different for each limited section 13. In addition to simple admission, other information such as limiting the time for admission may be included. The authority table 22 may be a table separate from the authority table 21 described above, or may be an integral table. In the case of a separate table, the above identification IDs may be grouped and authority may be set for each group.

The entrance management device 11 may have a table distribution means 30 that distributes a part or all of the information of the entrance authority possessed by the authority table 22 to the gate reader 16. By distributing the admission authority to the gate reader 16, the admission process at each gate 15 can be completed only by the gate reader 16 without making an inquiry to the admission management device 11 via the network each time. Therefore, the network load can be reduced, and even when an error such as a network disconnection occurs, the gate 15 can be operated if the individual gate readers 16 are operating, so that damage such as confinement can be less likely to occur. Here, when the information to be transmitted is not all but a part, only the information about the authorized person who has the entrance authority of the gate 15 possessed by the corresponding gate reader 16 may be transmitted to the gate reader 16. In this way, the amount of data transmitted and the amount of data used by the gate reader 16 can be reduced.

In addition to the above, the entrance management device 11 may have a history table 25 for recording the entry / exit history at each gate 15 for each identification ID. It is desirable for management to be able to execute the entry / exit history introduction means 31 that responds to the inquiry from the management terminal 17 or the dedicated terminal for checking the history with the information in the history table 25.

Further, the admission management system according to the present invention may be provided with a management terminal 17 for inputting data into the above-mentioned authority table 21 and authority table 22. When newly registering or canceling an employee or equipment to be an authorized person, or updating information, the employee or equipment is registered in the authorized person table 21. When changing the admission qualification to the limited section 13, it is registered in the authority table 22.

Further, the admission management system according to the present invention is a status confirmation terminal (which can access the above table to obtain information, such as checking for unauthorized use and checking the current admission status. (Not shown) may be connected. Further, the management terminal 17 may also have the function of the status confirmation terminal.

The gate reader 16 attached to the gates (gates 15a and 15b) has a short-range reading means 26 for reading the identification ID from the IC tag (HF band IC tag 14a) corresponding to the HF band using radio waves in the HF band. .. In addition to reading, information may be written to the HF band IC tag 14a. For example, the admission record may be written at the time of admission, and the admission record may be deleted at the time of confirmation of exit.

The gate reader 16 has a copy authority table 23 which is a copy of a part or all of the entrance authority managed by the entrance management device 11. Here, the admission authority managed by the admission management device 11 is the recorded content of the authority table 22 and is distributed by the table distribution means 30. The gate reader 16 may execute the authority synchronization means 33 that reflects a part or all of the transmitted authority table 22 information in the copy authority table 23. This may be that the authority synchronization means 33 is periodically executed to request transmission to the admission management device 11, or the table distribution means 30 is executed when the authority table 22 to be the master is changed. Then, when the data is transmitted, the authority synchronization means 33 may be passively executed. If only the record for the identification ID of the authorized person having the entrance authority who can pass through the gate 15 (15a, 15b) is held, the entrance may be refused if there is a request by the other identification ID. it can. Therefore, even a part of the admission authority works sufficiently. In addition, you may have all the information of authority table 22. In this case, the operation is always synchronized and has excellent backup performance.

The gate reader 16 has an entrance authority confirmation means 29 that refers to the copy authority table 23 for the identification ID recorded in the UHF band IC tag 14b or the HF band IC tag 14a. Of these, the identification ID recorded on the HF band IC tag 14a is referred to based on the data read by the short-range reading means 26 of the gate reader 16. On the other hand, the identification ID recorded in the UHF band IC tag 14b is referred to based on the data for which the identification ID is received via the reception interface 27 described later. Specifically, the reference is to confirm whether or not the authorized person having the identification ID has the authority to pass through the gate 15 provided with the gate reader 16.

The gate reader 16 has an entrance authority instruction means 28 that instructs the gate 15 whether or not to open the copy authority table 23 according to the reference result of the copy authority table 23 by the entrance authority confirmation means 29. That is, if the authorized person having the identification ID has the authority to pass through, the opening is possible, and if the authorized person does not have the authority, the opening is not. When the gate 15 can be opened, the electronic lock is unlocked, the screen or shutter is raised, or the automatic door is opened for the attached gate 15. If the door is not open, the electronic lock may be kept closed, the screen or shutter may be lowered or lowered, and the automatic door may be closed or kept closed.

The gate reader 16 may have an entry / exit temporary history table 32 that records the history of entry into the limited section 13 by the identification ID that allows entry when opening is possible. In the case of the entrance-specialized gate 15, it is sufficient to keep only the record of passing, and when the gate 15 allows both entry and exit, it is preferable to record both entry and exit. In this case, it is preferable to provide a pair of gate readers 16 on the exit side and share the history and management of entering and exiting with the paired gate leaders 16. Further, regarding the recorded history, it is advisable to execute the entrance / exit history transmission means 31 that sends the recorded history to the entrance management device 11 as needed. Although the entrance management device 11 is not in real time, the entrance / exit for each identification ID is recorded in the history table 25 at a required timing to grasp each entrance / exit.

Each table of the gate reader 16 is recorded in an internal storage device. Further, each means is executed by the arithmetic unit according to the recorded program. The gate reader 16 naturally has a storage device and an arithmetic unit, but they are omitted in the drawings.

If the gate reader 16 does not have the copy authority table 23, or if there is an error in the copy authority table 23, the gate reader 16 enters the entrance management device 11 via the network with respect to the identification ID for determining whether or not to enter. An admission authority inquiry means (not shown) that inquires about authority may be executed. In this case, the admission management device 11 refers to the authority table 22 which is the master, and executes the admission authority reply means (not shown) for returning the result of approval / disapproval to the gate reader 16.

When a plurality of gate readers 16 can be connected to each other, only some gate readers 16 may have the copy authority table 23. In this case, the gate reader 16 having no copy authority table 23 inquires the gate reader 16 having the copy authority table 23 for the admission authority. Upon receiving the inquiry, the gate reader 16 refers to the copy authority table 23 and returns the result.

Further, the gate reader 16 has a receiving interface 27 for receiving the identification ID transmitted from the UHF reader 18. This may be a physical port, an infrared port, or a wireless interface using a wireless LAN. However, the data sent from the UHF reader 18 may be in the same format as the UHF band IC tag 14b, and the information corresponding to the identification ID may be appropriately extracted or composited from the format. It is preferable to have software.

The UHF reader 18 comprises one or more devices. A transmission interface 35 having a medium-range reading means 36 that reads the identification ID from the IC tag corresponding to the UHF band using at least UHF band radio waves, and transmits the read identification ID to the reception interface 27 of the gate reader 16. Have. FIG. 1 shows an embodiment in which the control box 19 and the UHF antenna 20 are attached as separate housings. The control box 19 has a transmission interface 35, and the UHF antenna 20 has a medium range reading means 36.

The medium-range reading means 36 and the transmission interface 35 may be integrated in one housing. Further, a plurality of UHF antennas 20 may be connected to one control box 19. If the position and height of the UHF band IC tag 14b are different depending on the case, such as when it is installed on a vehicle such as a forklift or when it is attached to human clothing, a plurality of UHF antennas 20 are used. It is good to cover the required range evenly.

Next, a method of manufacturing an admission management system according to the present invention will be described by utilizing the infrastructure of the admission management system that does not correspond to the present invention. That is, it is a method of modifying the entrance management system. A functional block diagram of an admission management system that does not correspond to the present invention is shown in FIG. The entrance management device 11 is the same as the embodiment shown in FIG. On the other hand, instead of the gate reader 16, a non-compatible gate reader 41 is attached. The non-compatible gate reader 41 is compatible with the HF band IC tag 14a, and can read the identification ID by emitting radio waves in the HF band by the short-range reading means 26. On the other hand, it does not have the receiving interface of the gate reader 16 and does not have the means for receiving the identification ID of the UHF band IC tag 14b.

The following steps (1) to (3) are executed in no particular order for this admission management system. (1) As a step, a UHF reader 18 that reads the identification ID from the UHF band IC tag 14b corresponding to the UHF band using radio waves in the UHF band is added. It is necessary to install the hardware having the medium-range reading means 36 for reading the UHF band IC tag 14b in the UHF band. The installation is basically performed in the vicinity of the seat shutter 15b that allows passage by the UHF band IC tag 14b. If the seat shutter 15b is not within the reading range of the antenna by the medium-range reading means 36, it will have to move to the reading range for passing, which will take extra time and effort. Further, as a step (2), a receiving interface 27 for receiving the identification ID transmitted from the UHF reader 18 is added to the gate reader. This may be changed to the gate reader 16 by introducing the receiving interface 27 by modifying the non-compatible gate reader 41, or the non-compatible gate reader 41 may be replaced with the gate reader 16 in whole hardware. Further, as a step (3), the identification ID of the UHF band IC tag 14b corresponding to the UHF band is recorded in the admission authority. This means that a large amount of UHF band IC tags 14b will be introduced in order to make it possible to newly use UHF band IC tags 14b in a system that has used only HF band IC tags 14a until then. The identification ID of the UHF band IC tag 14b is recorded in the authority table 22 of the entrance management device 11, and together with the information in the authority table 21, the identification ID of each UHF band IC tag 14b allows the passage of which gate 15 to pass. Register whether or not it is permitted. If all the default values are rejected and the identification IDs of the UHF band IC tags 14b to be started to be used are registered in order, the load at the time of system introduction can be reduced.

As another step before and after steps (1) to (3), a step of replacing the door gate 15a for the HF band IC tag 14a with a hands-free gate such as a seat shutter 15b may be performed.

By performing the above steps (1) to (3), the admission management system shown in FIG. 1 (a) can be manufactured from the admission management system of FIG. The fact that the steps (1) to (3) are in no particular order means that the order of each step may be changed back or forth, or may be performed in parallel. Since the basic network wiring connecting each gate 15 to the entrance management device 11 can be used as it is, the wiring work only needs to be performed on a limited part around the gate 15, and the time and cost required for the work are the system and the cost. It can be compressed more than a complete network replacement.

A block diagram of a second embodiment of the admission management system according to the present invention is shown in FIG. FIG. 3A is a diagram showing an arrangement relationship with the limited section 13, and FIG. 3B is a simplified functional block diagram. Unlike the embodiment of FIG. 1, the gate reader 16 is not apparently installed in the gate 15 (seat shutter 15b) provided with the UHF reader 18. The transmission interface 35 of the control box 19 of the UHF reader 18 transmits the identification ID read from the UHF band IC tag 14b to the entrance management device 11. The admission management device 11 executes the admission authority confirmation means 51 to confirm the admission authority registered in the authority table 22 for the identification ID. When the admission authority is permitted, the admission management device 11 executes the admission authority instruction means 52 and transmits an instruction to release the seat shutter 15b to the gate reader 16 which can issue an unlocking instruction to the seat shutter 15b. .. The gate reader 16 is attached to the gate 15 (door gate 15a) and reads the HF band IC tag 14a, but also has wiring that can control gates other than the seat shutter 15a, and the instructed seat shutter 15b. Control is performed so as to open the door. In this embodiment, as the network infrastructure to be installed, the existing wiring from the entrance management device 11 to the gate reader 16 can be effectively utilized, and the network and individual hardware can be added to the existing wiring.

An example of a procedure when an authorized person uses the entrance management system according to the present invention is as follows. A gate 15 that can be opened / closed or unlocked electronically as hardware is attached to the doorway of the limited compartment 13. Among the gates 15, the gate reader 16 is attached near the doorway of the door gate 15a that should be passable by the HF band IC tag 14a. In addition, a seat shutter 15b that should be passable by the UHF band IC tag 14b is installed at any of the entrances and exits. Then, the UHF reader 18 is connected to the gate reader 16 so that the medium-distance reading means 36 of the UHF reader 18 can read the UHF band IC tag 14b approaching the entrance of the seat shutter 15b. The UHF reader 18 is wired so that the identification ID can be transmitted to the nearest gate reader 16 or the entrance management device 11.

As a preliminary preparation on the software, first, the identification IDs of employees and equipment are recorded in the authorized person table 21 through the management terminal 17 for the entrance management device 11 which is a server. For each limited section 13, the entry authority is recorded in the authority table 22 so that the admission authority is set for each identification ID or for each group in which the identification IDs are grouped by some division. Further, each of the gates 15 for entering the limited section 13 is provided with some kind of closing means, and a gate reader 16 having an entrance authority instructing means 52 for unlocking the closing means is attached. Information including the identification ID of the authorized person who is permitted to enter the limited section 13 is copied from the authority table 22 and distributed to each gate reader 16 by the table distribution means 30 of the entrance management device 11. The gate reader 16 executes the authority synchronization means 33 for copying the distributed admission authority to the copy authority table 23 in advance.

The procedure for the authorized person to use the admission management system executably manufactured by the above procedure will be described together with the flow chart of FIG. The admission management system to be executed is the first embodiment, that is, the embodiment of FIG.

First, the authorized person reaches the gate 15 which is restricted from entering the limited section 13 (S100). When the IC tag possessed by the authorized person is the HF band IC tag 14a (S101 → HF), the authorized person holds the HF band IC tag 14a over the gate reader 16 of the gate 15 to read it (S102). The short-range reading means 26 reads the identification ID from the HF band IC tag 14a (S103). On the other hand, when the IC tag possessed by the authorized person is the UHF band IC tag 14b (S101 → UHF), the authorized person approaches the detection range by the antenna of the UHF reader 18 provided near the gate 15 (S106). The identification ID is read from the UHF band IC tag 14b by the medium-range reading means 36 (S107). The UHF reader 18 transmits the read identification ID from the transmission interface 35 to the gate reader 16 (S108).

The gate reader 16 executes the entrance authority confirmation means 29 that refers to the copy authority table 23 (S111) for the read or transmitted identification ID. If the identification ID is not found (S111 → No), the admission authority instruction means 28 transmits to the gate 15 that the closure is instructed (S121). The same applies when the identification ID is found in the copy authority table 23 and there is no admission authority (S111 → Yes → S112 → No) (S121). When the identification ID is in the copy authority table 23 and there is an entrance authority (S112 → Yes), the entrance authority instruction means 28 transmits to the gate 15 that the opening is instructed (S113). As a result, the electronic lock of the gate is unlocked, or the shutter or the like is opened to allow entry (S114).

The standard adopted between the gate reader 16 and the UHF reader 18 and the IC tag 14 used in the present invention is a frequency band selected by a general standard used in RFID (radio frequency identifier) and NFC (Near Field Communication).
