CONSTITUTION:In a host 1, entering or leaving room conditions for respective terminal equipments 4a, 4b are set, and tables for the conditions are created. By gate IC cards, the tables according to the entering or leaving room conditions are read out of the host, and function as media for transmitting the entering or leaving room conditions according to the terminal equipments, but by fitting the gate IC cards in the terminal equipments, the entering or leaving room conditions according to the terminal equipments are read out of the gate IC cards by the terminal equipments, and conditions are set, and the conditions can be easily set by the terminal equipments. Besides, the capacity of the gate IC card is very large, and so the table of a large scale can be stored, and by reading the table once the conditions of a plurality of the terminal equipments can be set.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system for controlling entry and exit in a large number of areas such as a building and each room therein. The present invention relates to an IC card entry/exit management system in which an entrance/exit is unlocked by installing a terminal W and attaching an IC card as a key to the terminal.

[Conventional technology]

Conventionally, systems are known in which a card is used as a key to a room or the like. This is because a terminal device that is a league writer for the card is installed at the entrance of the room, etc., and the PIN number is stored on this terminal.The PIN number is also stored on the card, and this card is inserted into the terminal device. These passwords are compared, and when they match, the terminal operates the door unlocking means to unlock the door.

Conventionally, magnetic cards have been generally used as cards in this case, but there are problems in terms of data confidentiality, and the use of IC cards has also been proposed (
For example, see Japanese Patent Application Laid-Open No. 61-49081.

By the way, in such a system, there is no problem in cases where there is one-on-one correspondence between rooms and people using the rooms, such as in hotels, but, for example, in research institutes and factories,
If one person uses many rooms, a card for each room is required, and the more rooms are used, the more difficult it becomes to manage the cards, and the more difficult it becomes to find the card you want to use. It takes time and effort.

Therefore, as a way to deal with this, each terminal stores the PIN number of the card used for it, and when a card with a PIN number that matches one of these is inserted,
A system that unlocks the door, or a host side that manages the cards that can be used for each terminal, and when a card is inserted into the terminal, the terminal can unlock the door by installing this card. A system has been proposed in which the host side determines whether or not to lock the lock. According to these systems, a user can use one card as a key for multiple required doors.

[Problem to be solved by the invention]

However, with the above-mentioned conventional system that memorizes the PIN numbers of multiple cards used in the terminal, the number of PIN numbers that can be memorized is limited, and the PIN numbers can be entered one by one by operating the keyboard of the terminal. If there are a large number of terminals, it will take a great deal of effort and time to make the system usable. .

In addition, although the conventional system described above, in which each terminal is managed by the host side, may save the above effort, there is still a limit to the number of cards that can be identified, and furthermore, the host and terminal This requires wiring between terminals, which poses problems when installing the system, and it is not easy to add terminals or change the installation location.

SUMMARY OF THE INVENTION An object of the present invention is to provide an IC card person leaving room management system that solves these problems and allows work to be performed off-line and without much effort to make the IC card usable.

[Means to solve the problem]

In order to achieve the above object, the present invention sets a large exit condition that allows the host to unlock the entrance/exit for each area, and allows terminals in the area to communicate with the entry/exit conditions set for the area. A table indicating the correspondence is created, the table is read by the gate IC card, and by attaching the gate IC card to the terminal, the entry/exit conditions for the area where the terminal is installed are set according to the gate IC. It is read from the card and stored in the terminal.

[Effect]

In the host, entry/exit conditions are set for each terminal,
A table will be created for this. This major exit condition is assigned to each terminal one by one, and the amount of information is small.

The gate IC card reads this table from the host and functions as a medium to transmit the entry/exit conditions corresponding to the terminal, but by attaching this gate IC card to the terminal, The exit conditions are read from the gate IC card into this terminal and set, making it easy to set the conditions on the terminal. Moreover,
Since the gate IC card has a very large capacity, it can store large tables and can set conditions for a large number of terminals by reading the table once.

Furthermore, by setting entry/exit conditions for the terminal in this way, it becomes possible to unlock user IC cards that meet these conditions, and there is no limit to the number of user IC cards that can be used.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the IC card person exit management system according to the present invention, in which 1 is a host, 2 is a system card, 3 is a user card, 4a+4b are entry/exit terminals, and 5 is an electrical A lock controller, 6 is an electric lock, 7 is an automatic door controller, and 8 is an automatic door.

In the figure, entry/exit terminals are installed at the entrances and exits of security areas that require control of people's access, such as factories where specific people such as employees are allowed to enter and exit, and rooms where only a limited number of people can enter and exit. Here, it is assumed that the entry/exit terminal 4a is provided at the entrance of the club room, and the entry/exit terminal 4b is provided at the side gate of the building where this room is located.

In addition, entry/exit terminals are installed at all entrances and exits of the security area, but each entrance also has an entrance that enters the security area from outside this entrance and an entrance that enters the security area from here inside this entrance. A exit terminal for each person is installed on the exit side that goes outside. However, in FIG. 1, only two gate terminals 4a and 4b are shown, and the large exit terminal 4a is located on the entrance side of the club room entrance.
It is assumed that the room entry/exit terminals 4b are provided on the entrance side of the side gate of the building in which this room is located.

By the way, when considering the above rooms and buildings, generally,
Entrances and exits to and from the rooms in this building are strictly controlled. In other words, although there are relatively loose restrictions on the number of people who can enter and exit the building, there are strict restrictions on the number of people who can enter and exit the rooms within the building. Also, although they are on the same site, depending on the building inside, people may be able to come and go in and out slowly or strictly. In this way, when the access of people is strictly restricted, it is said to be high security, and conversely, when it is loosely restricted, it is said to be low security, and these high and low security levels are expressed as security levels.

Therefore, a security level is set for the entry/exit terminal according to the security level of the security area in which it is installed, but here, the entry/exit terminal 4a has a higher security level than the entry/exit terminal 4b. It turns out.

An electric lock controller 5 and an electric lock 6 are installed on the door of the room in which the entrance/exit terminal 4a is installed, and the entrance/exit terminal m4
A corresponds to the keyhole of this lock. In addition, the entrance/exit terminal 4b
An auto door controller 7 is provided at the side gate where the auto door 8 is set. 1'l
However, the entry/exit terminal 4b also corresponds to the keyhole of the key that turns the automatic door 8 into an operating state.

The user card 3 corresponds to these keys. This user card 3 is an IC card, and has the same security level as the room entry/exit terminal. A user card with a high security level can generally be unlocked in a security area with a high security level.

For example, if the security level of the user card 3 is higher than the security level of the large exit terminal R4a, the electric lock 6 can be unlocked by attaching the user card 3 to the entrance/exit terminal 4a. Instead, by attaching the same user card 3 to the entry/exit terminal 4b, the auto door controller 7 can also enable the auto door 8 to be activated. However, if the security level of the user card 3 is higher than that of the entry/exit terminal 4b but lower than that of the large exit terminal 4a, the auto door 8 is activated by attaching the user card 3 to the entry/exit terminal 4b. However, even if the user card 3 is attached to the entry/exit terminal 4a, the electric lock 6 will not be unlocked.

In this way, a security level is set for the user card 3, and when this security level is used, a comparison is made between this security level and the security level of the entry/exit terminal. Eligibility checks will be conducted for entry and exit.

Furthermore, with this user card 3, each time you enter or exit a security area,
An entry/exit terminal installed on the exit side writes data such as the number of the security area entered and exited, date and time of entry/exit, and records entry/exit history.

The security level settings for the user card as described above are performed on the host 1 terminal, and the user card 3
The entry/exit history recorded in the host 1 is transferred to the host 1, where it can be managed.

On the other hand, there are three types of system cards 2, which are IC cards: gate cards, alarm cards, and data cards. The gate card is used to set terminal conditions such as the security level of the exit terminals 4a and 4b for each person. These terminal conditions are created by the host 1 for each large exit terminal 4a, 4b, and written on the gate card. This gate card is attached to the entry/exit terminal for which terminal conditions are to be set, and the terminal conditions are read out from the gate card by operating the keyboard and stored in this large exit terminal. As a result, a security level is set on the entry/exit terminal.

Furthermore, each entry/exit terminal 114a, 4b records seven records of entry/exit (user card number, date/time of entry/exit based on the user card number, etc.). A data card, which is the system card 2, is used to collect the recorded entry/exit data from each large exit terminal and transfer it to the host 1.

If a user card is lost or stolen, in order to prevent unauthorized use of this user card by a third party, an entry/exit terminal that can use this user card will display a message indicating that this user card is an accident card. be registered. A user card registered as an accident card cannot be used at the emergency exit terminal. It is the alarm card as the system card 2 that registers the accident card in this large exit terminal. If there is an accident with the user card in this way, the data regarding the accident is input into the terminal of the host 1, read out, and written into the alarm card. Then, by attaching this to a predetermined room entry/exit terminal and performing a predetermined keyboard operation, the accident card is registered in this large exit terminal.

As described above, the IC card as the system card 2 functions as an information transmission medium between the host 1 and the room entry/exit terminals 4a and 4b. This allows the system to be taken offline, eliminates the need for wiring between the host 1 and each entry/exit terminal, and simplifies installation, making it easy to add more entry/exit terminals or change the installation location. become.

Next, the security level of the room entry/exit terminal and the user card in this embodiment will be explained.

The security level of the security area can be arbitrarily set in consideration of the relationship between the security areas, the level of entry/exit conditions for the security area, and the like. For security areas that need to be related to each other, the level of the security area with higher security is set to a higher level to create a relationship between high and low security levels. This is done by grouping into mutually related security areas, and assigning the above levels to each group. Therefore, each security area is associated in a tree structure.

FIG. 2 shows a specific example of a tree structure in which security areas are shown in association with each other.

In the figure, for example, it is assumed that Room A, Person B, Room B, Room C, and Warehouse are related, and the areas related to each other are grouped into one block. Then, each block is related in a tree structure by making sure that blocks that are related to the large exit condition are connected to one technique, and blocks that are not related to the entering and leaving conditions are connected to different techniques. There is.

In the tree structure shown in the figure, there are seven branches, and these techniques are coded 1, 2, 3..., 7 in order from the left.
Let us express it as In addition, each technique is classified according to the degree of entry/exit conditions, and these classifications are ranked 1, 2, 3, etc. from the top. ..., it is set to 6. Therefore, the entrance to room 9 is the entrance to room B.

The block consisting of room C1 warehouse has a code of 5 and a rank of 4.

For each block, the number written above the name of each area represents the number of the large exit terminal (gate terminal number) provided at the entrance/exit of this area. For example, the gate terminal number at the entrance and exit of Hall A, which is divided into blocks of code 1 and rank 5, is 1. Gate terminal numbers are sequentially assigned to the entry/exit terminals in each area.

Further, each block is numbered in order of area. This is the number enclosed in a circle below the area name, and is hereinafter referred to as setting gate N.

That's what it means. For example, the entry/exit terminal in Hall A is code 1, rank 5 block, and the set gate number is ■.

As described above, each area is divided and the relationship between each area is set, but between blocks that are connected to the same technique (same code), the lower the rank, the higher the security, and the lower the rank, the higher the security. This means that the security level of the entry/exit terminal is high.

User card 3, which is the key to the entrance and exit of the area (Figure 1)
The same level as the classification shown in FIG. 2 is also assigned. For example, when using user card 3 as the key to the entrance to room A of gate terminal No. 39, code 5. Set rank 4 data. This results in
User card 3 can be used as the key to the entrance to room A, but
Furthermore, it can also be used as a key for Room B Entrance 1 Room C1 Warehouse on the same level, and it can also be used for each area of the code 5, rank 5 block, code 5, rank 6 block on the lower level. It can also be used as a key.

The above are general functions of user cards, but even if the area is at the same level or a lower level,
It is possible to prohibit the function as a key. In addition, in general, the user card 3 cannot be used as a key for areas of blocks that are connected to other techniques (codes), but depending on the designation on the user card 3, it is not possible to use the user card 3 as a key for areas that are blocks of other codes. can also act as a key to designated areas. These matters will be explained in detail later.

In FIG. 2, only the IC card as a master key is at rank 1, and it is possible to unlock the entrances and exits of all areas. Also, at rank 2 are IC cards that serve as submasters for each code (S key, L key, M key, N key, A key, Q key).

Next, each card will be explained.

FIG. 3 shows the format of the user card 3 in FIG. 1.

The user card 3 includes an area where data serving as a heading for the card is stored (Fig. 3(a)), a storage area for basic key information [(Fig. 3(b)), and a storage area for key information (Fig. 3(b)). Figure (C)), option key information storage area (3rd
Figure (d)) and history information storage area (Figure 3 (e))
is provided.

First, in the heading storage area (Fig. 3(a)), the item No.
, Item No. 1 stores the business ID of Hiko 1 who owns this user card 3, Item No. 2 stores the expiration date of the business, and Item No. 003 stores the start date of use of the business.
0 item No. 2 is also the expiration date of this user card 3
, 4 is the level set for this user card 3 (item N
This is a field for specifying large exit terminals at the entrances and exits of areas where unlocking is prohibited in blocks of lower rank than (set in the rank and code field of 5), and a maximum of six terminals can be specified.

In item No. 5, first, the card status for identifying the system card or user card and the issue number of this card are stored. The level of this user card in FIG. 2 is set by the rank and code.

In history override, when the number of data stored in the history information storage shown in FIG. 3(e) exceeds a specified number (here, 40 pieces), one piece of old history information is deleted and new history information is stored. This flag instructs whether overrides are possible, such as writing new history information or prohibiting writing of new history information. In addition, the number of key information stored in the key information storage area shown in FIG. 3(c) and the number of option key information stored in the option key information storage area shown in FIG. 3(d) are also stored. , When issuing a new user card by Thiryu, etc., the card issue N of the old user card
o.

is stored as the accident card number.

In addition, in the case of a newly issued user card, by attaching it to the entry/exit terminal, this accident card no.
is registered in this large-leave terminal, and even if the old user card is found, it cannot be used thereafter on this large-leave terminal.

The basic key information storage area shown in FIG. 3(b) has the same code as the code set in item No. 5 in FIG. Information regarding the terminal is stored. The stored information includes the number of the entrance/exit terminal (gate terminal NO), entry/exit classification information indicating whether this large exit terminal is on the entrance or exit side of the area, and unlocking conditions. This information includes the flag, expiration date, start date of use, and time zone. These are provided for each stored gate terminal NO.

The unlocking condition flag indicates whether a PIN is required to unlock the lock.
This is a flag that determines whether an expiration date, start date of use, and time zone should be set, and one bit is used for each. These settings are independent of each other; for example, if the unlocking condition flag specifies that a password is only required, the lock can be unlocked at any time by using the password. Further, assuming that a password and a time period are determined by the unlocking condition flag, the door can be unlocked if the password is used within the set time period. Therefore, using the unlocking condition flag, it is possible to restrict the use of the user card based on the password, expiration date, and time of day. Note that the key usage start date represents the date when this user card is first attached to the terminal.

Among these low-rank entry/exit terminals, for large exit terminals whose use is particularly prohibited, please refer to item N in Figure 3 (a).
Specified by 084.

In the key information storage area shown in FIG. 3(c), the key information storage area shown in FIG.
), the information on the unlockable entry/exit terminals in the block at the same level as the code and rank set in item No. 5 is stored in the same format as in FIG. 3(b). Entry/exit terminals with the same code and the same rank that are not stored in this area cannot be unlocked with this user card.

In the option key information storage area shown in FIG. 3(d),
Other than the entry/exit terminal with the same code as the code set in item N015 of FIG. 3(a) and below the set rank,
For entry/exit terminals that need to be able to be unlocked at the same time,
Information regarding this large exit terminal is stored as an option key.

The format of this storage area is also the same as that in FIG. 3(b), but the amount of information stored therein is limited, and here,
A maximum of 10 areas are possible.

The numbers of large exit terminals stored in the above key information storage area and option key information storage area are shown in FIG. 3(a).
Item No. 5 is stored as the number of key information items and the number of option key information items.

In the history information storage area shown in FIG. 3(e), information indicating the entry/exit terminals that have been unlocked so far and their dates and times is stored as history information. The information stored includes the gate terminal No. 1 of the large exit terminal used to unlock the room, whether the large exit terminal is installed on the entrance or exit side of the area, the date of use, and the hour, minute, and second information. It is. There is also a limit to the amount of information that can be stored in this storage area, and here it is limited to 40 times of entering and exiting the area. Every time history information is recorded in this storage area, the history information pointer of item No. 5 in FIG. 3(a) is designated as a history information recording counter.

Information writing in the areas shown in FIGS. 3(a) to 3(d) of this user card is performed by the host 1 (FIG. 1) (however, the history information pointer of item N005 in FIG. 3(a) is Excluding <), information writing in the area shown in Figure 3(e), 3rd
Item No. in Figure (a).

Writing of the history information pointer No. 5 is performed when this user card is attached to the large exit terminal and the door is unlocked.

In addition, 1. This user card is used for the entry/exit terminals written in the area of Figure 3(b) (excluding the entry/exit terminals presented in item No. 4 of Figure 3(a)). ) and the third
The entry/exit terminals written in the areas shown in Figures (c) and (d) can be used for unlocking. Thus, for example, if a user card contains the code 5. in FIG. If rank 4 is set, the information in the area shown in Figure 3(b) allows code 5 to be used to unlock the room using the entrance/exit terminal in areas lower than ranks 5 and 6; )
If there is information in item No. 4, depending on this information, some areas may not be unlocked even at lower levels. Also, code 5. Even if it is a rank 4 area, the area shown in Figure 3 (c
) If there is no instruction in the area, unlocking in that area is not possible. Furthermore, if the option key information is present in the area shown in FIG. 3(d), it becomes possible to unlock even an area with a different code, for example, the entrance/exit terminal in hall A of gate terminal No. 1.

FIG. 4 shows the format of the gate card as the system card 2 of FIG.

As described above, this gate card is for transmitting information on the entry/exit conditions for each entry/exit terminal set at the host 1 to each entry/exit terminal. Although this gate card also has a heading area, the area for storing information on entry/exit conditions will be described here.

FIG. 4 shows this area, in which information for 50 entry/exit terminals can be stored. The information to be stored includes the gate terminal number of the entry/exit terminal, entry/exit discrimination information indicating whether this entry/exit terminal is installed on the entrance side or exit side of the area, and this information. Setting game in the block shown in Figure 1 of the entrance/exit terminal) No (■.

■, ...), the code, rank, M history overwrite permission flag, rank code management table, and whether or not the above information has been registered in the entry/exit terminal in Figure 1 of this entry/exit terminal. This is a check code indicating.

Each entry/exit terminal has a fixed storage capacity for historical information.
For example, let this be 500 items. The history overwrite permission flag is a flag that instructs what to do when the number of stored history information reaches 500 items. For example, when this flag is 1, when the number of stored history information reaches 500 items, new storage information will not be stored, and at the same time, this entry/exit terminal will not be usable. Furthermore, when this flag is 0, even if the number of stored history information reaches 500 items, new information can be stored (overwritten) while erasing old information, and a message is also output.

The rank code management table contains codes for entry/exit terminals of lower ranks relative to the set rank.

This is a table for managing ranks.

When the gate card with information stored in this way is attached to the entrance/exit terminal and the gate terminal number of this entrance/exit terminal is input, the information for this gate terminal No. stored in Fig. 4 is read out. Registered on the entry/exit terminal. Then, in the gate card, a check code (FIG. 4) indicates that information has been registered for this gate terminal number.

When this check code indicates that it has been registered, it is no longer possible to read the gate terminal number information for this check code, and as a result, the same gate terminal number is set for multiple entry/exit terminals. This can be prevented. Furthermore, the check code allows checking whether there is any information that has been omitted from registration.

FIG. 5 shows the format of the data card as the system card 2 in FIG.

As explained above, this card is a card for reading the history information stored in the entry/exit terminal and sending it to the host.

This data card has the heading ell shown in Figure 5(a).
It has an MA and a storage area for history information shown in FIG. 5(b).

When the data card is attached to the entry/exit terminal, the history information stored therein is sequentially read and sequentially written into the storage area shown in FIG. 5(b). At this time, Fig. 5(a)
In the heading area, the gate terminal number of the entry/exit terminal from which this history information is read is written in item No. 3, and when the information reading of this entry/exit terminal is completed, the number of history information read is also written. It will be done.

There are limits to the number of historical information that this data card can store and the number of entry/exit terminals, and here the former is 380 and the latter is 3. Therefore, when the number of stored history information reaches 380, it is no longer possible to write the history information, and when the number of stored history information reaches 380, Once read, history information can no longer be read.

If you want to read further historical information, you can either use another data card, or attach the data card to the host, transfer the historical information to the host, clear the contents of this data card, and reuse it. good.

FIG. 6 shows the format of the alarm card as the system card 2 in FIG.

As explained earlier, this card is used to set this information in the entry/exit terminal in the event that the user card is lost, stolen, or otherwise. area, an accident card storage area shown in FIG. 6(b), and a registration flag area shown in FIG. 6(C).

In the accident card storage area (FIG. 6(b)), for each accident card, the accident card number and the number of entrances and exits in the area that this card can be used to unlock (number of registered gates) are stored. Here, it is assumed that the information of six accident cards can be stored.

In the area shown in FIG. 6(C), a registration flag is set for each entry/exit terminal, and the area shown in FIG. 6(b) is equal to the number of accident cards that can be stored (i.e., 6). It is provided. In each area, 999 registration flags from 001 to 999 can be set, and each registration flag corresponds one-to-one with the gate terminal number of each entry/exit terminal.

Now, looking at the accident card registered first in Figure 6(b), there are several entry/exit terminals that this accident card can be used to unlock, and there are several entry/exit terminals that this accident card can be used to unlock. Set these entry/exit terminals. For this purpose, the registration flags corresponding to these entry/exit terminals in the area shown in FIG. 6(c) are set to 1. Registration flags corresponding to entry/exit terminals other than these entry/exit terminals are 0. In this way, after setting the registration flag for each accident card, when this alarm card is attached to the entry/exit terminal that can use the accident card, this entry/exit terminal is determined by the registration flag, and the accident card is is registered. When this registration is completed, the registration flag corresponding to this room entry/exit terminal becomes 2, and at the same time, the contents of the counter in FIG. 6(b) are incremented by 1.

In the same manner, when the accident card is registered in the necessary entry/exit terminal, the registration flag becomes 1-2 and the contents of the counter are incremented. When the contents of this counter match the number of registered gates, this This means that the accident card has been registered in all necessary entry/exit terminals. Therefore, it can be determined whether registration is completed by comparing the contents of the counter and the number of registered gates, and unregistered entry/exit terminals can be confirmed from the registration flag in FIG. 6(C).

Note that even a user card registered as an accident card can be made reusable. In this case, the information of this user card is similarly stored in the area shown in FIG. 6(b), and the registration flag in FIG. 6(C) corresponding to the entry/exit terminal used by this user card is set to 3. Make it. After this information is registered in the entry/exit terminal, the corresponding registration flag becomes 2, indicating that the registration has been completed.

In addition, a user card that specifies a deadline and cannot be used after this period can be treated as a similar accident card, and if this is registered in the entry/exit terminal,
When this period has elapsed, this user card becomes an accident card and cannot be used at this entry/exit terminal.

The formatting of the user card and system card has been described above, and now the operation of this embodiment will be described.

(Start-up Process) This process is a process for setting entry/exit conditions for each entry/exit terminal, and will be explained below with reference to FIG.

First, as explained in FIG. 4, when a gate card on which information on entry/exit conditions is written for each entry/exit terminal is attached to the entry/exit terminal (step 700), the system stored in this gate card A password check is performed (step 701).

This password consists of, for example, a password managed by the manufacturer and a password managed by the person purchasing and using the product. If this password is not correct (step 702), it is determined that the gate card is incorrect and an error message is output (step 71).
1) Eject the card (step 712).

If the password is correct, it is determined whether the card is an accident or not and whether the expiration date has passed (step 703). If the card cannot be used (step 704), an error message is displayed. output and eject the card. If the card is usable, it is determined whether this card is a gate card or another card (step 705), and if it is other than a gate card, an error message is output and the card is ejected. Entry/exit terminals that have not been processed for start-up will not accept anything other than gate cards.

If it is determined that the gate card is correct, a message to input the gate terminal number is output (step 706), and in response to this, the gate terminal number to be set to this large exit terminal is input by keyboard operation. (
Step 707), it is determined whether this gate terminal number is correct or not (step 708). As already explained in the figure, the process returns to step 706 to prompt the user to input the correct gate terminal number (this can be determined using the check code).

When the correct gate terminal number is input, information on the corresponding entry/exit conditions is read from the gate card (FIG. 4) (step 709) and written into the memory of this large exit terminal (step 710).

This completes the setting of entry/exit conditions for this large exit terminal (startup process), and the gate card is ejected (step 712).

The above startup process is performed for each entry/exit terminal. 5
If there are 0 or more entry/exit terminals, after starting up multiple gate cards or 50 entry/exit terminals, the host will request entry/exit conditions for other entry/exit terminals. All you have to do is read the information and perform the above process again for other entry/exit terminals.

(Card Processing) This process determines the type of card and performs processing accordingly, and is a process performed during actual use after the start-up process shown in FIG. 7. This process will be explained below with reference to FIG.

In the figure, steps 801 to 806 from inserting the card into the exit terminal to checking the accident card are steps 700 to 70 in Figure 7 for the previous gate card.
It is the same as 4.

If the inserted card is not an accident card (step 8)
07), the type of card is determined (step 808).

If this card is a user card, proceed to step 809; if this card is a gate card, proceed to step 810;
In the case of an alarm card, the process proceeds to step 811, and in the case of a data card, the process proceeds to step 812, and after predetermined processing is performed, the card is ejected (step 816).

Also, if the installed card is an accident card,
Step 81: Output alarm buzzer and error message
3), the contents of the card are destroyed (step 814).
) is discharged.

(Details of Step 809 in FIG. 8) When it is determined in step 80B of FIG. 8 that the card is a user card, the process proceeds to step 809 and user card processing is performed. This processing will be explained below with reference to FIG. 9.

First, it is determined whether the number of history information stored in the large exit terminal has reached the maximum number (500 in the above example) (step 900), and if it has not reached the maximum number, step 902)
If it has been reached, it is determined whether override is possible or not based on the history overwrite permission flag shown in FIG. 4 (step 901).

If override is possible, proceed to step 902;
If override is prohibited, a message is output (step 926) and the card is ejected (step 816 in FIG. 8).

Regarding the user card, the number of history information and whether override is possible or not are determined in the same way (step 902.90).
3).

Next, read rank and code information from the heading area of the user card (FIG. 3(a)) (step 904);
Next, these ranks, codes and gate cards (Figure 4)
Compare the rank and code set for this major exit terminal with step 905), and this major exit terminal is
Is it the same code and lower rank as the user card (this is called "card dominance"), is it the same code and rank as the user card (this is called "equivalent to the card"), or is it something other than these (this is called "card dominance")? This is called "out of card control") (step 906).

In the case of "card control", the main exit terminal of the prohibited lower rank is identified by item No. 4 in the heading area of the user card (FIG. 3(a)) (step 907), and then,
In the basic key information area of the user card (FIG. 3(b)), the unlocking condition flag is processed for major exit terminals other than the entry/exit terminals of the lower rank of prohibition (step 90).
8).

If it is "equivalent to the card", the key information area (FIG. 3(C)) of the user card is searched (step 909), and if no information is stored there (step 910), step 912 If the key information area stores information on another entry/exit terminal with the same code and rank, the unlocking condition flag for this major exit terminal is processed (step 911).

Additionally, if the card is out of control, or step 910
If the information cannot be found, the presence or absence of the option key information area (FIG. 3(d)) of the user card is determined (step 912); if there is no option key information area,
A message is output (step 926), the card is ejected (step 816 in FIG. 8), and even if there is an option key information area, this area is searched (step 91).
3) Even when information cannot be obtained (step 914), a message is output and the card is ejected. If information about a major exit terminal is found in the option key information area, an unlocking condition flag for this major exit terminal is processed (step 915).

In step 908, 911 or 916, the unlocking condition flag is processed, and this flag is used to advance the process shown in FIG.
As explained in b) to (d), when the expiration date is set to 1 hour, etc. (step 916), the basic key information area (FIG. 3(b)) and the -t--1 information area ( Figure 3 (C
)) or whether or not this user card has been used within the three-hour period within the expiration date set in the option key information area (FIG. 3(d)) (steps 917 to 9)
2o), and as long as these are satisfied, proceed to the next step 921. If none of the one-hour expiration dates are set according to the unlocking condition flag in step 916, the process directly advances to step 921.

In step 921, it is determined whether the unlocking condition flag requires the use of a password. If this is not requested, the entrance/exit is unlocked immediately (step 924), but if a PIN is requested, the PIN is input using the keyboard of the entry/exit terminal (step 922). and the password stored in the user card are verified in the user card (step 923), and when they match, the entry/exit terminal allows the entrance/exit to be unlocked (step 924).

If the two do not match, a message is output and the card is ejected.

After that, in the large exit terminal, the history information of the use of this user card is written in the memory, and the user card also has the history information of the unlocking performed with this large exit terminal. It is written into the history information area (FIG. 3(e)) (step 925).

(Details of step 810 in FIG. 8) This step 810 is for changing the entry/exit conditions of the entry/exit terminal using a gate card, and will be explained below with reference to FIG. 10.

The format of the gate card in this case is the same as that shown in FIG.

The gate card stores a PIN number, and when the PIN number is entered into the terminal by keyboard operation (step 1000), this is compared with the PIN read out from the gate card (step 1001). If these do not match, output a message (step 1
005) Eject the gate card (step 8 in Figure 8)
16).

If the above-mentioned PIN numbers match, 1, search for the gate terminal number set in this entrance/exit terminal in the area shown in FIG. ),
Information regarding entry/exit conditions for this room is read out and rewritten in the memory of this entry/exit terminal (step 1004). As a result, new entry/exit conditions are set in this entry/exit terminal. Search for this gate terminal N.

If the card cannot be found, a message is output (step 1005) and the card is ejected (step 81 in Figure 8).
6).

(Details of step 811 in Fig. 8) This step 8
11 is a process of registering an accident card in the entry/exit terminal using an alarm card, which will be explained below with reference to FIG.

The alarm card also stores the PIN number, and the 10th
The PIN number is verified in the same way as shown in the figure (step 11).
00.1101), and if the password is -, the entry/exit terminal reads out the number of accident card registrations from the heading area of the alarm card (FIG. 6(a)).Step 1102)
, determine whether this number is O (step 1103),
If it is 0, a message is output (step 111).
2) Eject the card (step 816 in Figure 8).

When the number of registered accident force and -do is not 0, the accident card number is read from the area shown in Figure 6(b) of the alarm card.
Step 1104) to read out the registration flag for the entry/exit terminal to which this alarm card is attached from the area shown in FIG. 6(C) Step 1105) It is determined whether the registration flag is 1 (step 1106).
When , the accident card No. is registered in the entry/exit terminal (Step 1107), and when the registration flag is 3, the registration of the user card as an accident card on the entry/exit terminal is canceled (Step 1108), respectively. The corresponding registration flag in the area shown in FIG. 6(c) on the alarm card is set to 2.

If the registration flag is other than 1.3, directly go to step 11.
Proceed to step 10.

After that, the count (I\N) is incremented by 1 (step 1110), and if this value N does not match the number of registered accident cards (step 1111), the next accident card number is read out and the same process is performed again. .and,
When the registration of all accident cards is completed, the cards are ejected.

(Details of step 812 in FIG. 8) This step 812 is a process of reading history information of the entry/exit terminal into a data card, and will be explained below with reference to FIG. 12.

The data card also has a PIN number, and first, the PIN number is verified in the same way as the previous cards (steps 1200 and 1201). Next, the number of history information and the number of room entry/exit terminals stored in the data card are read from the heading area (FIG. 5(a)), and it is determined whether or not this data card can be used (step 1201). If it is not available, send a message (step 120).
9) Eject the card (step 816 in Figure 8).

Step 1203: If the data card can be used, read the history information stored in this entry/exit terminal.
), written to the data card (step 1204), and the total number of history information written to the data card is 3.
80 (step 1205) and whether all the history information of this entry/exit terminal has been written to the data card (step 1206), and when either of these is satisfied, the number of entry/exit terminals is determined. (step 1207), and write this and the number of history information on the data card in the area shown in FIG. The number is also written to this data card at the same time (step 120B).

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to set the conditions for each terminal offline, and the work of setting the conditions is simple, and there is no limit to the number of user cards that can be used. can be obtained.
