Only if the current time falls within the time zone set for the business, the I
This allows C card holders to enter and leave the room.

Specifically, for example, the owner of the IC card 1 whose entry/exit condition information is stored as job A is permitted to enter/exit the room only between 8:00 and 17:00.

Therefore, as mentioned above, by setting the time period for allowing entry and exit for each entry/exit permission information, it becomes possible for only appropriate persons to enter and exit the room according to the business hours.
It is possible to accurately prevent persons unrelated to work from entering and leaving the room.

Note that the gate control unit 13 controls the memory unit 3 of the IC card 1.
The entry/exit trace information is written in the room entry/exit trace information, and the entered/exit trace information is sent to the host computer 15. The host computer 15 stores the sent entry/exit trace information in a built-in storage device.

FIG. 3 shows the appearance of the room entry/exit control device 11.

That is, as mentioned above, the card reader/writer section 12
and a gate control section 13, which have a structure that can be separated from each other. On the front side of the card reader/writer unit 12, there is a card insertion slot 22 for a card reader/writer 21 that accepts the inserted IC card 1 and reads or writes data to the memory unit 3, and information such as a password.

47 is R that stores the control program of CPtJ45, etc.
OM, 48 is a RAM for data storage, and 49 is a serial input/output port, which are connected to the CPLJ 45. 50 is a host interface that connects the serial input/output port 49 and the host computer 15.

Next, the operation of such a configuration will be explained with reference to the chart shown in FIG. First, when a card user inserts his or her IC card 1 into the card insertion slot 22,
The card reader/writer 21 takes in the inserted IC card 1, reads out room entry/exit condition information, etc. in the memory section 3, and sends it to the CPLJ 31. The CPtJ 31 performs various checks, such as comparing the read entry/exit condition information with the entry/exit permission information in the RAM 33. For example, first, it is checked whether the IC card is usable or not.

If the IC card is unusable, the buzzer 41 sounds and a card return command is sent to the card reader/writer 21 to return the accepted IC cart to its insertion slot 22 and display a message to that effect on the liquid crystal display 25. indicate. If the IC card is usable and accident card information is stored in the RAM 33, a check is made to see if it is the accident card. Here, what is an accident card?
This is a card that must be registered by the card user when the card is lost or stolen. If it is an accident card, the buzzer 41 is sounded, the accepted IC card 1 is returned to the insertion slot 22, and the liquid crystal display 25 displays the fact.

If it is not an accident card, next check the card expiration date. If the expiration date has expired, the buzzer 41 will sound and the accepted IC card 1 will be inserted into its insertion slot 22.
, and a message to that effect is displayed on the liquid crystal display 25.

When it is determined that there is no abnormality in the IC card itself as described above, it is then confirmed that the user of the IC card is an authorized user. That is, the liquid crystal display 2
5, the user is guided to input the password, and when the password is input from the keyboard 23, the password is compared with the password stored in the memory section 3 of the IC card 1. If the passwords do not match, a buzzer 41 is sounded, the accepted IC card 1 is returned to its insertion slot 22, and a liquid crystal display 25 indicates the fact. If the PIN numbers match, it can be determined that the person attempting to enter or leave the room using IC card 1 is the authorized user of this IC card 1. Next, the entry/exit condition information is compared with the entry/exit permission information. , check if any of the information matches, and if it is necessary to check the time zone, confirm that the current time corresponds to the time zone corresponding to the matched information, and enter the following. Perform the exit process. The necessity of checking the time zone is determined because if the IC card 1 is like a master card or has no time limit, there is no need to restrict entry and exit based on time.

In the entry/exit process, CPtJ31 first uses IC card 1.
The entry/exit trace information at this time is written into the memory unit 3 of the controller. For example, write information such as when (year, month, day, time, etc.) you entered and left the project. In addition, year, month,
Day and time information is obtained from a clock circuit 34. Next, the CPU 31 checks whether this entry/exit trace information has been written normally or not. If there is an abnormality, the CPU 31 sounds the buzzer 41 and returns the accepted IC card 1 to its insertion slot 22. If it is normal, the CPU 31 returns the accepted IC card 1 to its insertion slot 22, unlocks the electronic ring 14, and makes the selection possible.

At the same time, the CPU 31 transfers the room entry/exit trace information to the post computer 15 and stores it in the host computer 15. That is, the entry/exit trace information is temporarily stored in a buffer area secured within the RAM 33. When a transfer request is received from the host computer 15, it is checked whether or not data exists in the buffer area. The data within the area is transferred to the host computer 15, and if the area does not exist, data indicating this is transferred to the host computer 15. The host computer 15 stores the transferred data (room entry/exit trace information) in a built-in storage device. Next, it is checked whether the data has been transferred normally to the Hoscodon computer 15, and if there is an error, the error data is stored in the buffer area.

When the electronic ring 14 is unlocked, time monitoring is performed. That is, the entry/exit time is set, and if the electronic ring 14 is not opened within the set time after being unlocked, the electronic ring 14 will be locked. Furthermore, after opening the electronic ring 14, the buzzer 41 is made to sound unless the set time has elapsed until the electronic ring 14 is closed, and continues to sound until the electronic ring 14 is closed. Finally, when you close the electronic K114, it will be automatically locked.

Next, as a result of checking the entry/exit condition information, if there is an abnormality etc., the operation after sounding B', l'-41 and returning the IC card 1 will be explained with reference to Fig. 6 (d'). do. After returning the IC card 1, the CPtJ31 creates an error status and temporarily stores it in a buffer area in the RAM33. And host computer 1
When there is a transfer request from 5, it is checked whether data exists in the buffer area, and if it exists, it is transferred to the buffer area.
The data within the area is transferred to the host computer 15, and if the area does not exist, data indicating this is transferred to the host computer 15. The host computer 15 stores the transferred data in its built-in storage device. next,
It is checked whether the data has been transferred normally to the host computer 15, and if it is normal, the process ends, and if it is an error, the error data is stored in the buffer area.

By storing entry/exit trace information such as the entry/exit time in the memory of the IC card, and unlocking the electronic door for entry/exit, the above-mentioned room entry/exit trace information is transferred to the post computer and stored. , it is possible to memorize and leave traces of entry and exit, allowing for strict entry and exit management.

In the embodiment described above, the time zone information is registered in the gate control unit 13, but it may be included in the entry/exit condition information stored in the IC card 1.

That is, to explain in detail with reference to FIG. 7, the IC card contains information on the entry/exit conditions for entering and exiting rooms, each of which has different entry/exit permission information set. Time zone information for time-limiting entry and exit is stored in each of these, and when entering and leaving the room, it is necessary to ensure that the work as entry/exit condition information in the IC card 1 matches the entry/exit permission information. In addition to this, the IC card holder is only allowed to enter or leave the room if the current time falls within the time zone set for the matching business. Specifically, for example, according to entry/exit condition information for work A, entry/exit to the corresponding room is permitted between 81:00 and 17:00.

In such a configuration, when the aforementioned IC card 1 is inserted into the card reader/writer section 12, the card reader/writer section 12 reads at least one entry/exit condition stored in the memory section 3 of the IC card 1. The information is read and sent to the gate control section 13.

The gate control unit 13 checks at least one entry/exit condition information sent from the card reader/writer unit 12 with pre-registered entry/exit permission information, and determines whether any of the information matches. It detects that the current time is included in the time zone information set in the corresponding entry/exit condition information, and unlocks the C electronic screen 14.

Therefore, as described above, by setting the time period for allowing entry and exit for each room entry/exit condition information, only appropriate people can enter and leave the room according to the business hours, and It is possible to accurately prevent unauthorized persons from entering and leaving the room. In addition, by doing this, by storing multiple pieces of entry/exit condition information in the IC card 1, a person entering/exiting the room can enter/exit a room with different required entry/exit permission information using only one IC card. This makes it possible to eliminate the need to own multiple magnetic cards.

Furthermore, in this embodiment described above, a time element is added to the entry/exit condition information or entry/exit permission information for gate control, but the element is not limited to this. For example, as shown in FIG. elements may be added. Specifically, F
indicates that entry/exit permission information is stored for his work A that allows him to enter and exit the room on days other than Sundays and holidays. Furthermore, Mr. G is shown to have stored entry/exit permission information that allows him to enter and exit the room on Mondays, Wednesdays, Fridays, and Saturdays, excluding holidays, for his work B. Similarly,
This indicates that Mr. H has stored entry/exit permission information that allows him to enter and exit the office from February 1st to May 30th, excluding holidays, regarding his work C.

[Effect of the invention 1] As described in detail above, according to the present invention, the permission information storage means stores entry/exit permission information and information indicating the effective time of verification in each of these, and the information is stored within the set effective time. Entry/exit is permitted by detecting a match between entry/exit condition information read from a portable electronic device and entry/exit permission information; Entering/exiting condition information and information indicating valid verification times for each of these are stored, and the entering/exiting conditions information read from a portable electronic device within the set valid time and pre-registered entry/exiting permission are stored. Since entering and exiting the room is permitted by detecting a match with the information, it is possible to add the element of time to the control of entry and exit, and it is possible to perform more strict entry and exit management than in the past.

Further, according to the present invention, the entry/exit condition information including the entry/exit permission date is stored in the portable electronic device, and is registered in advance with the entry/exit condition information read from the portable electronic device on the entry/exit permission date. Since entry and exit is permitted by detecting a match with the entry/exit permission information provided, strict room entry/exit management can be performed similarly.
