Description

The present invention relates to an entrance / exit management system using a laundry 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 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 card, and if it can be confirmed that the ID is permitted to enter the limited area, the doors and gates are temporarily unlocked and opened for employees. Allow staff to enter.

However, in areas where there is concern about contamination or removal of specific foreign substances, such as factory manufacturing sites, uniforms themselves and non-pockets are recommended. Naturally, the IC card hung from the neck with a string not only has a risk of foreign matter being mixed in, but also has a risk of involving the IC card hanging from the neck if there is a rotating device or the like.

On the other hand, as in Patent Documents 3 and 4, it has been proposed to attach a laundry IC tag to a cloth product containing clothes and to complete the authentication by clothes (FIGS. 1, [0008] [0014]. etc). In Patent Document 3, a wash-resistant data carrier (laundry IC tag) is enclosed in a bag-shaped body attached to the inside of clothes so that it can be washed. As a result, the authentication function can be continuously provided without any problem even after cleaning. Patent Document 4 proposes to use an electronic tag attached to the upper arm. However, Patent Document 4 aims to control washing in terms of radiation control in nuclear facilities.

Applying this, a method has been proposed in which a plurality of dedicated uniforms are distributed to each individual and the information of the IC tag attached to the uniform is associated with the information of the ID card in advance (Non-Patent Document 1). If you authenticate with an ID card when you enter the changing room and have the reader read the IC tag of the uniform you wear that day when you enter the limited area from the changing room, only that uniform will be temporarily IDed. It allows you to enter as a substitute for a card.

Monthly Food Factory Manager September 2016 Issue "Special Feature: Food Defense Measures"

However, if uniforms are provided to each employee as a special item and then an attempt is made to use the entrance / exit management system using uniforms, the burden of the number of uniforms will increase. There are many unused uniforms, and it is not possible to lend or borrow as needed. This is the same whether the company buys the uniform when it is introduced or leases (rents) it from a company that rents the uniform. Especially in an environment where there are many short-term part-time workers and part-time workers, and the number of staff changes and increases and decreases rapidly, it is desirable to share uniforms except when wearing them in order to reduce costs.

Therefore, the present invention is an IC that should be carried by the free uniform that is temporarily lent to the individual when necessary while sharing and managing the free uniform that has the IC tag for laundry and is not associated with the individual. The purpose is to provide an entrance / exit management system that can be used as a substitute for a card.

The present invention includes an entrance / exit management server, a deregistration terminal, a gate, and a gate reader.
The entrance / exit management server can be entered / exited by the employee ID recorded on the employee IC tag attached to the identification card, the uniform ID recorded on the uniform IC tag attached to the free uniform, and the gate. Enter the admission authority for the restricted area
The employee ID and the uniform ID are temporarily linked via the deregistration terminal.
Regarding the uniform ID read by the gate reader, the above problem is solved by determining the presence or absence of the above authority information for the employee ID from the above association and determining whether or not the gate can be opened. I did.

As a constitution of this invention, the following form was created.
As hardware
Entrance / exit management server and
The employee ID recorded on the employee IC tag attached to the identification card and the uniform ID recorded on the uniform IC tag attached to the free uniform can be read by short-range wireless communication, and the above entrance / exit management server. A deregistration terminal capable of transmitting the above employee ID and the above uniform ID to
A gate that restricts entry and exit into the limited area, which is opened according to the response from the entrance / exit management server.
A gate reader that is attached to the gate, reads the employee ID and uniform ID, and sends them to the entrance / exit management server.
Have. In addition, there may be a controller with or attached to a gate and a gate reader.

The above entrance / exit management server
An employee table that records the above employee ID and
For the employee ID, an authority table that records the authority to enter the limited area, and
A uniform table that records the above uniform ID,
A usage table that can temporarily associate the employee ID and the uniform ID,
Have.
On top of that, the above entrance / exit management server
Upon receiving an instruction to temporarily associate the pair of the employee ID and the uniform ID sent from the registration cancellation terminal, an immediate association registration means for registering the information of the pair in the usage table, and
Upon receiving an instruction to cancel the temporary association of the uniform ID sent from the registration cancellation terminal, an immediate association release means for releasing the pair of information including the uniform ID in the usage table, and
Can be executed.
Furthermore, the above entrance / exit management server
For the uniform ID sent from the gate reader, the corresponding employee ID is requested in the usage table, and based on the record of the authority table for the employee ID, the entrance authority for instructing whether or not to open the gate is instructed. Instruction means and
A table distribution means for transmitting a copy of the used table and the authority table to the gate, the gate reader, or a controller attached thereto, and
Have at least one of. When the entrance / exit management server has the entrance authority instruction means, an inquiry is made to the entrance / exit management server via the network when opening the gate. When the entrance / exit management server has the table distribution means, the gate, the gate reader, or a controller attached thereto holds the gate without inquiring to the entrance / exit management server when opening the gate. By referring to the copy of the above table, it is judged whether or not to release it on the spot.

The uniform ID is not associated with the employee ID in the normal state, and each uniform is treated as a shared state that does not belong to the individual employee. Such uniforms that do not belong to an individual are referred to as free uniforms in the present invention. Before entering the limited area, the employee is made to read the employee ID of the identification card and the uniform ID of the free uniform to be worn on that day into the above-mentioned deregistration terminal so as to be paired. The deregistration terminal sends an instruction to temporarily associate this pair with the entrance / exit management server. The entrance / exit management server records this temporary association in the usage table. After that, until this link is released, employees can pass through the gate by having the gate reader read the uniform ID of the free uniform instead of the identification card when entering the gate. Become. The entrance / exit management server, or the gate, the gate reader, or the controller attached to the gate, the gate reader, or the controller attached to the gate to which a copy of the usage table and the authority table related to the entrance authority is transmitted and written in advance corresponds to the uniform ID. The employee ID is obtained from the usage table, the entrance authority at the location where the gate reader is installed is determined for the employee ID, and the gate is instructed whether or not to enter.

The instruction that the entrance / exit management server temporarily associates the pair of the employee ID and the uniform ID transmitted from the registration cancellation terminal was about the employee ID recorded in the usage table. In some cases, more efficient operation becomes possible if there is an immediate linking overwriting means that overwrites the existing pair of information. When the employee corresponding to the employee ID changes his / her free uniform, when the uniform ID of the new free uniform is temporarily linked to the employee ID, the uniform ID of the free uniform that he / she was wearing until then Since the ties can be released, it is possible to prevent an intruder who tries to enter the above-mentioned limited area by wearing a free uniform that the employee has taken off. As a result, the free uniforms that the employees have changed can be safely sent out for cleaning, and the possibility that the free uniforms that have been taken off will be misused can be greatly reduced.

The present invention eliminates the risk of hanging identification cards for entry into restricted areas and internal activities, while distributing only the required number of uniforms for use without having them dedicated to individual employees. Entrance / exit management with free uniforms can be realized.

In addition, even if the association is not released, the authority of this free uniform can be released within a certain period of time by setting, so that the abuse of the free uniform can be prevented.

A functional block diagram showing a third embodiment of the entrance / exit management system according to the present invention.

Hereinafter, the present invention will be specifically described. The present invention relates to an entrance / exit management system that manages human entry into a limited area, an entrance / exit management server that provides the function, an entrance / exit management program that operates servers and terminals, readers, and gates according to the means. It is an entrance / exit management method that is the operation procedure of. The entrance / exit management program does not correspond to a single device, but is a group of programs that operate in conjunction with a plurality of devices.

An example of the first embodiment of the entrance / exit management system according to the present invention is shown in FIG. The entry / exit management program of the entry / exit management server 11 constituting the present invention manages the opening / closing of the gate 15 that restricts entry to the limited section 13 that only authorized persons can enter. The entrance / exit management server 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 employees here for convenience, the actual operation target is not limited to employees.

As the gate 15, a door having an electronic lock 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 a seat shutter 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 is attached with a gate reader 16 capable of reading an IC tag. The target that can be read here does not have to be limited to the following uniform IC tags, and other IC tags may also be readable and can be used together. From the viewpoint of security, it is preferable that the gate reader 16 is arranged at a position close to the gate 15. If the door has an electronic lock, it is preferably on the wall surface next to the door. In the automatic ticket gate type opening / closing door, it is preferable that the door is provided on the upper surface or the side surface of both side portions of the automatic ticket gate type.

In operating the present invention, it is more preferable that the gate reader 16 is provided at a position where the uniform IC tag attached to the free uniform described later can be easily read. When the uniform IC tag is attached to the free uniform on the sleeve portion of the long sleeve, the degree of freedom in the installation position of the gate reader 16 is increased. On the other hand, when the uniform IC tag is provided on a portion of the free uniform that is difficult to move, such as the flank, it is preferable to provide the gate reader 16 at a location where it can be easily read.

Each of the above employees is given a unique employee ID as an identification code. In actual operation, the employee is distributed an identification card including an employee IC tag recording the given employee ID. The shape of the identification card is not particularly limited, but it needs to be portable, and a commonly used card-type identification card can also be used in the present invention. For example, there is a name tag type identification card that is hung from the neck.

The employee will be temporarily provided with the free uniform. Here, "temporary" means the working hours of the day at the longest, and in principle, it is desirable for security to be returned at the end of work. Free means that the management or ownership may be a company or an organization, but it is not exclusive to a specific employee or the like in terms of normal use and handling management. Here, the uniform is a uniform or an accessory to the uniform in the workplace where the limited section 13 is located. From the viewpoint of convenience, it is preferable to include upper body clothing such as a shirt, but it is not particularly limited, and it can also be used with arm covers, shoes, hats, and the like. However, the merits of the present invention can be maximized on the top and bottom of clothes that are not particularly dangerous to fall or get caught.

The free uniform used in the present invention has a uniform IC tag that can read the recorded uniform ID by short-range wireless communication at some places. In the case of the above-mentioned free uniform which is divided into two or more such as an arm cover, shoes, a shirt and trousers, it may be attached to one of the parts. In particular, it is preferable that the sleeve is provided near the wrist because it is easy to handle when authenticating with the gate reader 16. The uniform IC tag needs to have water resistance to the extent that it does not break down even in an environment such as washing with water to be cleaned. Further, it is desirable that the uniform IC tag is fixed with sufficient strength such as being put in a small bag and sewn so that the uniform IC tag is not separated from the free uniform in normal washing.

When the above-mentioned employee enters the limited section 13, not only the entrance authority can be authenticated by the identification card by the employee IC tag on which the employee ID is recorded, but also the uniform of the free uniform worn at that time. The process of enabling authentication by the IC tag is performed by the entrance / exit management server 11 and the registration cancellation terminal 12 capable of network communication with the server 11. That is, the present invention can be used even in an environment in which a person who does not wear a free uniform but is authorized to enter the room exists. The situation may be such that the uniform IC tag can also be used for admission. On the other hand, it is possible to completely limit the target of admission to those who wear the above free uniforms without any problem in operation.

The entrance / exit management server 11 has an employee table 21 for recording the above-mentioned employee ID. The employee table 21 may have specific information such as an employee's name and address in addition to the employee ID. In addition, the contents may be shared or diverted from the personnel management database used in other operations.

The entrance / exit management server 11 has an authority table 22 for recording the entrance authority to the limited section 13 for the employee ID. When there are a plurality of limited sections 13, admission authority may be given to the employee 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 employee table 21 described above, or may be an integrated table. In the case of a separate table, the above employee IDs may be grouped and authority may be set for each group.

The entrance / exit management server 11 has a uniform table 23 for recording the uniform ID. In addition to the uniform ID, other information such as the shape, size and color of the free uniform, cleaning history, and the like may be included.

The entrance / exit management server 11 has a usage table 24 for temporarily associating and recording the employee ID and the uniform ID. The use table 24 may be a table integrated with the employee table 21. However, the association information of the usage table 24 can be rewritten and is not associated by default. By each means described later, the association is registered when the above uniform is used, updated when the free uniform is changed, and the association is released when the use of the free uniform is completed. However, the past association information may be left as the usage history of the free uniform.

Further, in addition to the above, the entrance / exit management server 11 may have a history table 25 for recording the entry / exit history at each gate 15 for each employee ID.

The registration cancellation terminal 12 for performing the link registration to the usage table 24 is connected to the network connected to the entrance / exit management server 11. If the registration cancellation terminal 12 is provided in or near the changing room, the above-mentioned immediate linking can be performed when the free uniform is provided or when the change of clothes is completed, so that the operation of the personnel can proceed smoothly.

Further, in order to input data to the employee table 21, the authority table 22, and the uniform table 23, it is preferable that the management terminal 17 is connected to the network separately from the registration cancellation terminal 12. When a new employee is registered or canceled, or information is updated, the employee is registered in the employee table 21. When changing the admission qualification to the limited section 13, it is registered in the authority table 22. When a free uniform is newly introduced, washed, or disposed of, it is registered in the uniform table 23. However, the deregistration terminal 12 may also have these functions.

Furthermore, the above network has a status confirmation terminal (not shown) that can access the above table to obtain information, such as checking for unauthorized use and checking the current admission status. It may be connected. Further, the management terminal 17 may also have the function of the status confirmation terminal.

Furthermore, if the network has an IC card reader that reads the uniform ID and is provided with a release-dedicated terminal 18 that instructs the entrance / exit management server 11 to release the association of the uniform ID, at the end of work. It is preferable in the congestion of. At the end of work, the free uniform must be taken off and the association must be released, but congestion can be alleviated if the immediate release means described later can be executed simply by reading the uniform ID.

A procedure example of the operation method in the first embodiment of the entrance / exit management system having the above configuration and each means executed by the entrance / exit management program on the server and the terminal will be described below. First, as a preliminary preparation, the employee ID of the employee is recorded in the employee table 21 through the management terminal 17. Further, the free uniform has already been introduced, and the uniform ID is recorded in the uniform table 23. Each employee ID is set to belong to one or more groups, and the limited section 13 is recorded in the authority table 22 so that the entrance authority is set for each of the above groups. The table 24 used is not temporarily linked.

Employees who come to work at the start of work will be lent a shared free uniform. Which free uniform to rent is not employee-specific. However, free uniforms may be distinguished by size, color, etc. For example, in the changing room, the employee immediately associates the employee ID of the employee IC tag given to the identification card with the uniform ID of the rented free uniform. The flow at this time is shown in FIG.

First, (S101), the registration cancellation terminal 12 is displayed on the screen so as to read the employee IC tag of the identification card. The employee causes the IC card reader 12a connected to the registration cancellation terminal 12 to read the employee IC tag accordingly (S102). The registration cancellation terminal 12 executes an employee registration inquiry means for inquiring to the entrance / exit management server 11 whether or not the employee ID recorded in the employee IC tag is registered. Upon receiving the inquiry, the entrance / exit management server 11 executes an employee registration confirmation means for searching the employee table 21 for whether or not the employee ID is normally registered, and registers the result of the correctness. The employee registration reply means to be transmitted to the release terminal 12 is executed. The registration cancellation terminal 12 that receives the result of this correctness (S103), if it is not properly registered (S103 → No), displays an error on the screen and ends the immediate association (S104).

If it is properly registered (S103 → Yes), the registration cancellation terminal 12 displays the uniform IC tag so as to be read by the IC card reader 12a. The employee reads the uniform IC tag according to the attached instruction (S111). The registration cancellation terminal 12 provides an immediate linking instruction means for instructing the entrance / exit management server 11 to temporarily link the pair of the user ID recorded in the uniform IC tag and the previous employee ID. Execute. Upon receiving the instruction, the entrance / exit management server 11 executes the uniform association confirmation means for determining whether or not the record of the uniform ID exists in the use table 24, that is, whether or not the record of the uniform ID is already associated with the employee ID. If it is already linked, multiple registration will be performed, so the linking existence notification means for transmitting an error to the registration cancellation terminal is executed (S113 → Yes). The deregistration terminal that has received the error displays on the screen that the free uniform has already been linked, and immediately ends the linking (S104). If not linked, the entrance / exit management server 11 registers the paired information in the usage table 24 according to the instruction for temporarily linking the pair of the uniform ID and the employee ID. Is executed (S115). After registering the paired information, the entrance / exit management server 11 transmits to the registration cancellation terminal 12 that the association is complete. Upon receiving the completion, the registration cancellation terminal 12 displays the registration completion on the screen (S120).

Further, FIG. 3 shows a flow in which another process is added to this registration flow. If the uniform ID has not been linked (S113 → No) after executing the above uniform linking confirmation means (S113), the employee ID is further linked to another uniform ID in the use table 24. Execute the employee association confirmation means for confirming whether or not there is any (S114). If it is not linked (S114 → No), the employee is not lent a free uniform at this time, so the process is performed in the same manner as in the flow of FIG. 2 (S115 → S120). On the other hand, if it is tied (S114 → Yes), it means that the employee has already been lent a free uniform and will change into a new free uniform. Therefore, from the use table 24, the information of the pair of the employee ID and the previous uniform ID is cleared, and the information of the pair of the employee ID and the new uniform ID is overwritten on the use table. 29 is executed (S116, S121). As a result, even if the free uniform that has been taken off is left unlinked without being unlinked, it will not be illegally invaded by the free uniform.

After registration, even if the employee does not carry the identification card and keeps it in a locker in the changing room, he / she can enter the limited section 13 where the employee is allowed to enter by authentication with the uniform ID. The processing at that time will be described together with the flow of FIG.

First, the employee reaches the gate 15 which is restricted from entering the limited section 13 (S201). The employee holds the uniform IC tag over the gate reader 16 provided attached to the gate 15 and reads it by short-range wireless communication (S202). The gate reader 16 transmits the read uniform ID to the entrance / exit management server 11 in order to inquire whether the corresponding gate 15 can be unlocked and admission is permitted.

The entrance / exit management server 11 executes a linked search means for obtaining the corresponding employee ID in the usage table 24 for the transmitted uniform ID (S203). If the temporary linking record for the uniform ID is not found (S203 → No), the uniform is not linked, and the entrance / exit management server 11 returns to the gate 15 that it refuses to open. Execute the lock refusal notification means. Upon receiving the refusal, the gate 15 maintains the locked state without opening and sounds an error sound (S204). If a record of association is found in the usage table 24 (S203 → Yes), the record of the authority table 22 regarding the entry authority to the limited section 13 corresponding to the gate 15 for the employee ID corresponding to the uniform ID. The admission authority confirmation means for requesting is executed (S211). The entrance / exit management server 11 executes the entrance authority instruction means 28 for instructing the gate 15 whether or not to open the gate 15 based on the record in the authority table 22. That is, if the employee ID has the authority to enter the limited section 13 corresponding to the gate 15, a signal to the effect that the opening is permitted is sent to the gate 15 (S211 → Yes → S212). If the employee ID does not have the authority to enter the limited section 13 corresponding to the gate 15, a signal indicating that the opening is refused is transmitted to the gate 15 (S211 → No → S204). In addition to the judgment in units of employee IDs, it may be requested whether or not the employee ID can be opened depending on whether or not the employee ID belongs to the group having the authority to open the gate 15. Upon receiving the signal to permit opening, the gate 15 makes an unlocking sound and unlocks the electric lock of the gate 15 (S213).

The entrance / exit management server 11 may record the contents and results of inquiries from the above gate 15, the fact that admission is permitted, the time, and the like as a history. In FIG. 1, a table for recording this history is described as a history table 25. It is desirable for management to be able to execute the entry / exit history introduction means 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.

At the end of work, the employee will break the link between the uniform ID and the employee ID and return the free uniform. The registration cancellation terminal 12 whose setting has been changed to the mode for accepting cancellation, or the cancellation-only terminal 18 is used. Here, the registration cancellation terminal 12 will be described as an example. The employee causes the IC card reader 12a of the registration cancellation terminal 12 to read the uniform ID. At this time, it is not necessary to read the identification card. The registration cancellation terminal 12 executes an association cancellation instruction means for transmitting an instruction to temporarily release the association of the read uniform ID to the entrance / exit management server 11. Upon receiving this instruction, the entrance / exit management server 11 executes the immediate link release means 27 that releases the paired information including the uniform ID in the use table 24. As a result, it is not possible to enter with a free uniform whose paired information has been released, and it is possible to safely take it out to the outside, such as cleaning and disposal.

In addition, when canceling the registration cancellation terminal 12 and the cancellation dedicated terminal 18, in order to prevent the association of the uniform ID that was read by mistake from being released, once the uniform ID is read, it is not sent immediately and is confirmed on the screen. May be displayed, and the touch panel or mouse of the registration cancellation terminal 12 and the cancellation-only terminal 18 may be operated to approve the request, and then the above-mentioned association cancellation instruction means may be executed. Further, instead of approval, the above-mentioned unassociation instruction means may be executed by reading the same uniform IC tag when a confirmation request is displayed on the screen. In the latter case, no particular operation is required, and the IC card reader only needs to read the card twice, which makes it easier to deal with congestion at the end of work.

As the standard adopted in the gate reader 16 and the IC card reader 12a used in the present invention, general standards used in RFID (radio frequency identifier) and NFC (Near Field Communication) can be used. The corresponding IC tag can be used for the employee IC tag and the uniform IC tag.

Specifically, the uniform IC tag, the employee IC tag, and the wireless standard of the gate reader that reads them may be in the UHF band or the HF band. In the case of the HF band, short-range wireless communication according to ISO15693 can be used. The uniform IC tag and the employee IC tag are manually brought close to each other to a short distance of about 10 cm or less for authentication. 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.

On the other hand, in the case of the UHF band, since it can be read even if there is a certain distance from the gate reader, it is installed in a passage or door, and when an employee passes through it, the uniform IC tag or the employee is automatically used. So-called hands-free authentication can be realized by reading the IC tag and enabling automatic authentication. Especially in a work environment where hands are easily blocked, such as when carrying in luggage or operating a machine tool, it may be difficult to read the uniform IC tag very close to the gate reader even if it is placed on the sleeve, so the convenience of the UHF band. Highly sexual. In addition, even at a site where authentication is performed while riding on a forklift or cart, it is difficult to approach the gate reader 16 near the wall while riding, so a UHF band that can be read from a slightly distant place is effective. However, since the UHF band inevitably has a wide authentication range, there is a risk that a third party may get mixed in and authenticate, or authentication of a plurality of persons may be accepted in parallel and cause a malfunction. Therefore, when the gate reader in the UHF band is used, it is preferable that the gate reader, the controller, and the like are installed in a narrow space so that a plurality of people do not enter the detection range.

Next, a second embodiment of the present invention will be described with reference to FIG. The difference from the first embodiment is that first, a copy of the master table of the authority table 22 and the usage table 24 held by the entrance / exit management server 11 is periodically made by the table distribution means 30, or each gate 15 as needed. It is at the point where it is transmitted to the controller 19 of. The controller 19 is either an integral housing with the gate 15 or the gate reader 16 or is directly connected by a very short distance cable. FIG. 5 shows an example in a separate housing. The signal between them does not require at least network communication such as Ethernet and can operate independently of the network. However, it is connected to the network for communication with the entrance / exit management server 11.

The controller 19 has a copy table of the authority table 22 and the use table 24. Further, when a new table is distributed as a response to the push distribution by the table distribution means 30 of the entrance / exit management server 11 or the table distribution request means that requests copying from the controller 19 side (not shown), the data is updated as appropriate. To do. Then, when the gate reader 16 reads the uniform ID of the uniform IC tag or the employee ID of the employee IC tag, the gate 15 does not need to contact the entrance / exit management server 11 every time to determine the opening authority of the gate 15. By executing the entrance authority instruction means 28 of the controller 19, the gate 15 can be opened according to the authority without going through the network. By adopting the structure of this second embodiment, even if the network or server is temporarily down, authentication can be performed based on the information immediately before that, and operation with high durability against troubles becomes possible. ..

Further, in this embodiment, the load on the entrance / exit management server 11 can be reduced. In the present invention, since the free uniforms are temporarily linked, the load on the server tends to be relatively large, but in this embodiment, the controller 19 accesses the server at the time of individual entry / exit. Since the processing can proceed without any problems, the load on the entrance / exit management server 11 can be greatly reduced. The controller 19 may transmit when the records of the temporary entry / exit history table 32 are accumulated to some extent, and if the frequency of synchronization is appropriately suppressed, the network traffic can be reduced.

The controller 19 enters / exits information such as the employee ID or uniform ID inquiring about entry to the directly connected gate 15, the employee ID or uniform ID that has been permitted to open, and their time. It is recorded in the temporary history table 32. On top of that, if the entry / exit history transmission means 31 that is periodically sent to the entry / exit management server 11 is executed, it is preferable that the management of the movement and placement of employees and the like can be synchronized. The entrance / exit management server 11 to which this is sent updates the information in the history table 25 as appropriate.

Further, a third embodiment, which is another embodiment of the present invention, will be described with reference to FIG. Similar to the second embodiment, the entrance / exit management server 11 executes the table distribution means 30 that distributes a copy of the authority table 22 and the usage table 24 periodically or upon request. This copy is held by the gate reader 16a via the controller 19. In this embodiment, the entrance authority according to the read employee ID or uniform ID can be determined by independently executing the entrance authority instruction means 28 only by the gate reader 16a. Therefore, it can be driven independently in normal times. Although not shown, if a battery is mounted so that the gate 15 can be unlocked with a minimum amount of electric power, it is possible to determine unlocking while maintaining security even in the event of a power failure. On the other hand, the read employee ID, uniform ID, time information, and the like are temporarily recorded in the entry / exit temporary history table 32 of the controller 19. The controller 19 executes the entry / exit history transmission means 31 that appropriately transmits in response to the network traffic and the load of the entry / exit management server 11.

In FIG. 6, the gate reader 16a emits radio waves in the UHF band to generate an area in front of the gate 15 where the IC tag can be read, and the employee IC tag or the uniform IC tag that has entered this area is displayed. It shows an example of automatically reading and enabling hands-free use.

Although not shown as another form, the gate 15 itself may have these functions in addition to the gate reader 16 having the authority table 22, the use table 24, and the entrance authority instruction means 28. Further, the gate reader 16 and the gate 15 itself may be integrated, and similarly, the authority table 22, the use table 24, and the entrance authority instruction means 28 may be provided.

As yet another form, in the case of battery drive, by limiting to short-range communication using radio waves in the HF band instead of the UHF band, it is possible to suppress battery consumption and enable long-term independent drive.

The entrance / exit management system according to the present invention may be operated integrally with another system using recognition by an IC tag. For example, it may be operated together with an employee ID and a mobile machine entry / exit management system that manages entry of a machine such as a forklift. Further, since it is a system that manages employee IDs, it may be combined with an employee attendance / leaving management system together with entrance / exit.
