Any rule generates the approval number by a simple arithmetical operation rule, and an office employee keeps one of the approved rule in mind, and can enter a room since an electric lock by inserting through an ID card and inputting the same password as the approval number at the time of entering the room.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room entrance management device configured to permit entry into a room by confirming the identity of the person by the code number of an ID card and a personal identification number entered by a key.

[0002]

2. Description of the Related Art An entry management device which has been widely known in the past is a personal identification number input device having ten numeric keys 0 to 9 as disclosed in, for example, Japanese Patent Application Laid-Open No. 2-171815. And a card input means (reading means) that uses an IC card in which a personal identification number is recorded in a memory, and compares the four-digit personal identification number keyed in with the personal identification number read from the IC card. I was judging whether to allow or not to enter the room.

Further, in the case where the comparison of the above-mentioned personal identification numbers is inconsistent and the operation of the inconsistency continues three times in a row, the IC card is prohibited from use, and
The IC card, which was once prohibited, had a mechanism in which it was not permitted to enter the room even if the temporary security code was keyed in correctly, unless the administrator performed a special release operation on the room management system.

However, the room entrance management device configured as described above is effective when strict security management is required, such as room entrance management of a room in which important materials such as trade secrets are stored. It is possible to use it to exert a sufficient security effect, but in the case of entrance control where security management does not require so much strictness, that is, only employees who know the PIN are allowed to enter the room and do not know If the security management is simple enough to prevent employees from accidentally entering or mischievously entering the room, use the above-mentioned IC card or enter a 4-digit PIN from 0-9.
It is not necessary to make a combination of 10 numbers of
If a personal identification number input device using a C card or 10 keys is used, there is a problem that the entire structure of the entrance management device becomes complicated and expensive, and therefore improvement thereof has been desired.

Therefore, if such strict security management is not required, an ID card (employee card made of magnetic card) possessed by each employee is used without using an expensive IC card, It was considered that the ID code number, that is, the employee number is used as it is as the personal identification number to manage entry into the room. According to the entrance management device using this ID card, a personal identification number input device having at least four small keys can be used, and the personal identification number is purposely stored in the memory of the host computer (management device). Since there is no need and no need to use expensive IC cards, it has the economic advantage of being able to greatly reduce costs, and it has an ID.
In addition to the card, it is not necessary to carry an IC card dedicated to entering the room, and it is not necessary to remember each personal identification number for entering the room, so that an advantage of being able to easily perform complicated entrance management can be exerted.

[0006]

As described above, the ID
Entering a room using a card is very convenient for relatively moderate security management, but the ID code number of each employee can be easily known by others from the employee list or time card. Also, since the code number of each person magnetically written on the ID card (magnetic card) can be easily deciphered, the entry is managed only by the ID code number of each person who can easily know these. In that case, there was a problem that many unauthorized entrances occurred and security management could not be fully achieved.

Further, in order to enable the use of the card which has been prohibited due to the error of the personal identification number again, the manager of the entry management system is notified as described above, and the manager releases the prohibited state. However, in the case of the above-mentioned entry management system where security management is not so strict, it is rare to have an administrator on the spot, and if possible, it will be canceled without the intervention of the administrator. In particular, it is not preferable to attempt unauthorized entry, but in view of the high rate of card-use prohibition errors simply because the person who has forgotten his / her PIN number in the room, the prohibition of use is prohibited without administrator intervention. It was desired to be able to release it easily.

Therefore, the technical problem of the present invention is that it is possible to surely achieve the entrance control by using the ID card carried by each person, and to prohibit the use of the card based on the personal identification number error without the intervention of the administrator. It is to allow the person to release it relatively easily.

[0009]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows. I
An entrance management device configured to confirm the person by comparing the code number read from the D card with the personal identification number entered by the key, and open the electric lock to permit entry when both numbers match. And

(1) A personal identification number storage means for temporarily storing a personal identification number input by a key, and a permission number generation means for generating a permission number from the code number of the ID card described above according to a preset arithmetic processing rule. This permission number is compared with the above-mentioned temporarily stored personal identification number, and if they match, an electric lock is opened, and if they do not match, an entrance control means configured to issue an alarm.

(2) The arithmetic processing rule for generating the permission number from the code number of the ID card adds a positive number to the end of the ID code number, multiplies the ID code number by 10, or determines the reciprocal of the ID code number. Or, it should be configured by a relatively simple four arithmetic operation rule such as adding the reciprocal number to the end of the ID code number.

(3) When the mismatch judgment between the personal identification number entered by the key input and the generated authorization number occurs continuously for a certain number of times within a certain period of time, the code number of the used ID card is used as the prohibited number and data is used. An ID that is stored in memory and that prohibits the use of ID cards with this code number thereafter
Corresponding ID after a certain period of time has passed since the card prohibition method and the prohibited code number were last entered
Providing a means for canceling the prohibition of use of the card automatically.

[0013]

The above means operates as follows. Above (1)
According to the means described in, the code number written on the ID card is not used as it is as the personal identification number, but the permission number generated from this code number is used as the personal identification number in accordance with the pre-programmed arithmetic processing rule. Therefore, even if you know the ID code number of another person, you cannot calculate the permission number unless you know this calculation processing rule, and write both the calculation processing rule and the permission number on the ID card itself. This permission number, that is, the personal identification number cannot be deciphered even if the magnetic information is read because it is not embedded. Therefore, it is possible to perform entrance control with a high security effect using an ID card that is low in cost. To do.

According to the means described in (2) above, since the permission number is generated using various relatively simple four arithmetic operation rules based on each person's ID code number, the person entering the room can use this permission number. That is, it is possible to reduce the rate of forgetting or making a mistake in the personal identification number, and to minimize the occurrence of personal identification number errors.

According to the means described in the above (3), even if the use of the ID card is prohibited due to a personal identification number error, the use prohibition is automatically released after a certain period of time (for example, about 5 minutes), Since the prohibition of use of the ID card can be released without the intervention of the administrator, the release process when the password is temporarily forgotten or the key is entered by mistake is extremely easy and Allows you to do it quickly. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the above-mentioned entrance control apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a front view showing the external appearance of a personal identification recorder used in the present invention. The employee number (code number) of each person is attached to the front of the recorder 1 installed at the entrance of a room for managing entry. An insertion groove 2 for inserting an ID card (not shown) made of a magnetic card that has been written, and I inserted in the insertion groove 2
Magnetic reader 3 that reads the code number from the D card, and a total of 4
A keyboard 4 for inputting a personal identification number, which is composed of individual number keys
, An OK lamp 5 that lights up when the personal identification numbers input by the key and the card match, and an error lamp 6 that lights up when the personal identification numbers do not match.

FIG. 2 is a block diagram showing an electrical configuration of the recorder 1 and a CPU 7 forming the center of the control unit.
Is a ROM 9 which stores a system program via a bus 8 and a calculation processing rule for generating a permission number, which will be described later.
Also, it temporarily stores the personal identification number that is keyed in, and stores the ID code number that has an error or NG.
A memory including an AM 10, a timer device 11 for setting an error time, a key input time, or an NG time, which will be described later, an interface circuit 12, and a control circuit 13 for opening and closing an electric lock are connected, and further, an interface is provided. The circuit 12 is connected to the magnetic reader 3, the keyboard 4, the OK and error lamps 5 and 6 described above, and a sounding device 14 that sounds when an error occurs and notifies the error. Each is structured so that it is controlled and operated according to the system program stored in the ROM 9.

FIG. 5 shows an embodiment of an arithmetic processing rule for generating a permission number, that is, a personal identification number from an ID code number stored in advance in the ROM 9 described above. The second rule adds 1 to the end (last digit) of the ID code number read from the ID card to generate a permission number, and the second rule also multiplies the ID code number by 10 to generate a permission number. , The third rule also uses the reciprocal of the ID code number as the permission number, and the fourth rule adds the reciprocal of the ID code number to the end (final digit) of the ID code number. Therefore, each processing rule is structured to generate a permission number using the relatively simple four arithmetic operation rules as described above, and each employee remembers one of the preset arithmetic processing rules. Place, is hitting the entry, by performing the key input of the same security code as authorization number generated and inserted in the ID card by the processing rule, it has a mechanism comprising allow entry electric lock is open.

Next, the procedure for entering the room will be described in more detail with reference to the flow charts shown in FIGS. The illustrated process uses any one of the first, second, and fourth rules among the process rules shown in FIG. The ID code number written on the ID card is a four-digit number that is a combination of the numbers 1 to 4, but it goes without saying that all of these conditions are merely examples.

When entering a room, first step S1
Then, the error and the ID code number which has been NG are temporarily stored in the RAM 10 are cleared, respectively, and then the process proceeds to steps S2 and S3 to set the error time and the NG time of the timer device 11 to 0 seconds respectively, and further , The process proceeds to step S4, and an initial process for clearing the array K [], which is also temporarily stored in the RAM 10, that is, the permission number generated by the arithmetic processing rule, is performed, and then the process proceeds to step S5 to input the keyboard 4 It is the key input of the personal identification number or the I by inserting the ID card.
It is determined whether the D code number is input.

If it is determined in step S5 that the key input is made, the process proceeds to step S6 to set the key input time limit of the timer device 11 to 10 seconds, and then the process proceeds to step S7 where the sounding device 14 performs the key input. When a click sound is emitted and the key input of the personal identification number is completed in step S8, the process proceeds to step S9 and the personal identification number keyed is temporarily stored in the RAM 10 described above. Incidentally, step S
If no key is input within the time set in step 6, the process returns to step S4 and is reprocessed.

If it is determined in step S5 that the ID code number is read and input by inserting the ID card, the process proceeds to step S10, and the timer device 11 described above is entered.
The key input time of is reset to 0 seconds, and then the process proceeds to step S11, where the read ID code number is RAM10.
It is determined whether or not the ID code number that has been NG registered is matched, and if they do not match (when there is no registered data at the time of the first input operation, all do not match), the process proceeds to step S12 and key input is performed. The first 4 digits of the generated personal identification number are compared with the above ID code number, and the next step S1
The result is judged at 3. When the entrance process is performed using the third rule of the arithmetic processing rules shown in FIG. 5, the personal identification number is compared with the permission number generated in accordance with the rule in step S12, and step S described below is performed.
The processes of 14, S15 and S16 are omitted.

If it is determined in step S13 that the first four digits match, the process proceeds to the next step S14, and the secret code is executed in accordance with the first, second, or fourth rule of the arithmetic processing rules shown in FIG. The lower digit of the number is generated, and then the procedure proceeds to step S15, and the lower digit generated and the remaining digits of the keyed-in personal identification number, that is, 5 digits and subsequent digits are compared, and these digits are compared in the next step S16. If it is determined that the numbers match, the process proceeds to step S17, the control circuit 13 opens the electric lock to enable entry, and further, in step S18, the OK lamp 5 is lit for 2 seconds to enter the room. To finish.

On the other hand, when it is determined that the above-mentioned steps S13 and S16 do not match, step S2 shown in FIG.
Proceed to step 1 and the ID code number that is not matched is RAM
It is determined whether or not the ID code numbers that are registered in error in 10 match, and if they do not match (there is no match because there is no registered data during the first input operation), this ID code number is used. After registering the error ID code number in the RAM 10 and then proceeding to step S23 to set the error time of the timer device 11 to 60 seconds,
In step S24, the error lamp 6 is lit for 3 seconds, and the sounding device 14 warns that there is an error.

Further, when it is judged that the ID code numbers which are not matched in the above step S21 match the ID code numbers which are respectively error-registered in the RAM, that is, they are set in the above step S23. If it is determined that the same mistake as the first mistake has been repeated within the error time, the process proceeds to step S25, the ID code number having this mistake is registered in the RAM 10 as an NGID code number, and then to step S26. Then, the NG time of the timer device 11, that is, the NG release time is set to 5 minutes, and the process proceeds to the next step S27 to set the R
After clearing the error ID code number registered in the AM 10 as an error, and further resetting the error time of the timer device 11 to 0 seconds in step S28, the process proceeds to step S29 and the error lamp 6 is lit for 40 seconds, and The sounding device 14 warns that the use of the ID card is prohibited. For the ID card whose ID code number is NG registered in step S25, the NG registration is automatically released and reused after the NG release time set in step S26 has elapsed since the last input. It will be possible.

Further, when it is determined that the ID code number input in the above step S11 and the registered NGID code number match, it is determined in step S19.
Proceed to step 40 to turn on the error lamp 6 for 40 seconds, and warn that the sounding device 14 is forbidden to use, and then proceed to step S20 to set the NG set in step S26.
Reset the release time to 5 minutes. Therefore, when an ID card whose ID code number is NG registered and which is prohibited from use is reused within the NG release time, the NG release time is repeatedly reset.

[0027]

As described above, according to the entrance management apparatus of the present invention, the entrance management can be realized easily and at low cost by using the ID card possessed by each person. However, in the present invention, in particular, the ID code number written on the ID card is not used as the personal identification number as it is, but the permission number generated from this ID code number is used by using a relatively simple arithmetic processing rule. Since it is used as a personal identification number, the personal identification number cannot be calculated only by looking at or decoding the ID code number. Therefore, a relatively high security effect can be achieved for the simple structure in which the ID card is used as an input means. This is an advantage that can surely achieve entrance control, and even if NG registration due to a PIN error occurs, this NG registration after a certain period of time is automatically Is released, it became disabled ID
Coupled with the fact that the card can be reused without the intervention of the administrator, it can be used for entry control of various rooms where the administrator is not resident and does not require such strict security management. It is suitable for.
