Description

  The present invention relates to an entrance / exit management system for managing traffic, and for example, relates to an entrance / exit management system for managing entrance / exit of a building.

  There is an employee management network system that ensures security by ensuring that checks are performed without waiting, such as when a business traveler enters or leaves a business establishment from one business establishment to another business establishment (for example, Patent Document 1).

  When an employee of the A office travels to the B office, information related to the business trip of the business traveler (traveler information) is transmitted from the employee management system of the A office to the employee management system of the B office. . In the employee management system of business office B, business trip information is temporarily registered in the temporary registration area. When a business traveler comes to the B office and the ID card carried by the business traveler is read at the entrance gate, the employee management system of the B office checks whether or not the information on the business traveler is registered and is registered. In some cases, the entrance gate is opened to allow entry.

JP 2002-73919 A (first page, FIG. 1)

  However, the conventional technique has the following problems. Since visitors from outside the company do not have information for identifying the visitor, entrance / exit management using the employee management system cannot be performed. Therefore, it is necessary for a visitor to perform a predetermined procedure at the counter of a guardhouse or the like when entering. For example, the visitor's company name, name, visitor, business, etc. are entered on the visitor form and the time stamp is stamped at the window. Furthermore, in order to open the entrance gate, it is necessary to use a visitor ID card or to be accompanied by a visitor who owns the ID card. After the request is completed, ask the visitor to stamp the previous visitor form, submit it to a counter such as a guardhouse, and leave. It was necessary to follow such annoying procedure.

Furthermore, visitors from other offices in the same business entity must satisfy the following three conditions.
1) A plurality of business establishments have an employee management system for managing the information (employee information) of their employees, and each employee carries an ID recording medium on which personal identification information is recorded. .
2) A network has been established so that the employee management systems at each office can communicate with each other.
3) An ID recording medium issued by each office and a card reading unit (hereinafter referred to as a card reader) that reads the ID recording medium are configured according to the same standard and can be read from each other.

  The above 1) and 2) are likely to become popular in large enterprises in the future, but are often not realized in small and medium enterprises. Further, in ID recording media (hereinafter referred to as ID cards), contactless IC cards have become widespread, but even though standardization is progressing, contactless IC cards are still not compatible between manufacturers. .

  In other words, in order to satisfy the above condition 3), ID cards and card readers of all offices must be ordered from the same manufacturer. Making the card reader and the ID card monopolized by one company causes the principle of price competition not to work and leads to rigid introduction costs. In addition, when introducing the system in order to all business sites, the business sites that are introduced later are subject to restrictions that must be matched to the standards of the first business site, and the latest technology at that time may be introduced. There is also a problem that it becomes impossible.

  The present invention was made in order to solve the above-described problems. For visitors who do not have personal identification information registered in the entrance / exit management system, the reception is eliminated to save labor and ensure security. The purpose is to obtain an entrance / exit management system.

The entrance / exit management system according to the present invention includes a personal identification code input unit for inputting a personal identification code and a personal identification code storage unit for storing use restriction information corresponding to the personal identification code, and the personal identification code input to the personal identification code input unit. Is an entrance / exit management system comprising a traffic management control unit for comparing traffic codes with password codes stored in the password code storage unit and performing traffic management based on the verification result and use restriction information. The management area is subject to a hierarchical structure consisting of a main management area and a plurality of sub-management areas within the main management area, and a PIN code input unit is provided for each management area, The personal identification code storage unit further stores the usage restriction information corresponding to the personal identification code for each management area corresponding to the personal identification code input unit, and the traffic management control unit includes the personal identification code. Collating the personal identification code stored in the PIN code and PIN code storage unit which is input to the de-input unit, and the verification results for each management area performs traffic management on the basis of the use restriction information set individually In traffic management in the main management area, verification is performed using all digits of the password, and in traffic management in a plurality of sub-management areas, verification is performed using some digits of the security code .

  The entrance / exit management system of the present invention is based on an input operation of a personal identification code by a visitor whose personal identification information is not registered in the entrance / exit management system having previously obtained a personal identification code necessary for entry. Can enter. Thereby, it is possible to obtain an entrance / exit management system that eliminates reception and saves labor while ensuring security.

Embodiment 1 FIG.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The entrance / exit management system in the following embodiment manages the entrance / exit of employees at a certain office, and also manages entrance / exit of visitors from outside and visitors from other offices (hereinafter referred to as visitors). It is related to the case of performing together. Moreover, the case where an ID card is used as an input means of the personal identification information assigned to the employee is shown. Further, in the following embodiments, a password is used as a security code used for visitor entrance / exit management, and the security code input unit and the security code storage unit are respectively a security code input unit and a security code storage unit. Are listed.

  FIG. 1 is a configuration diagram of an entrance / exit management system according to Embodiment 1 of the present invention. FIG. 2 is a diagram showing a management area for performing entrance / exit management according to Embodiment 1 of the present invention. First of all, I will explain the entrance / exit management for employees in the office (hereinafter referred to as employees). The employee already has an ID card 1 in which personal identification information is written. FIG. 1 and FIG. 2 show a case where entrance / exit management of an area composed of a toilet, office B, and office C is performed, and traffic management of three doors is performed. That is, a door 5a for entering and leaving the entire area, a door 5b for entering and leaving the office B, and a door 5c for entering and leaving the office C are provided, respectively. These traffic management will be performed.

  The doors 5a to 5c are provided with electric locks 4a to 4c, and are controlled to be opened and closed by the traffic management control unit 3. The employee has an ID card 1 in which personal identification information is written in advance. When unlocking the door, the employee causes the ID card 1 to be read by the personal information setting units 2a to 2c provided in the vicinity of the doors 5a to 5c. Here, the personal information setting units 2a to 2c are used as a general term for both the personal information reading unit and the personal identification number input unit, and details will be described later with reference to FIG.

  The traffic management control unit 3 includes a personal identification information storage unit (not shown) that stores personal identification information for permitting traffic. The traffic management control unit 3 collates the personal identification information in the ID card 1 read by the personal information setting units 2a to 2c with the personal identification information stored in the personal identification information storage unit. If the collation results match, the electric locks 4a to 4c corresponding to the personal information setting units 2a to 2c that have previously performed the reading operation of the ID card 1 are unlocked.

  Next, entrance / exit management for visitors will be described. The visitor does not have the ID card 1 in which personal identification information is written. In such a case, entrance / exit management using a personal identification number is performed as an alternative to personal identification information, and the following procedure is taken.

  An employee who accepts a visitor operates any of the personal computers 8a to 8c connected to the in-house network 7 to access the server 6 and inputs the number of visitors and usage restriction information. The usage restriction information includes data on the validity period and the number of validity for each password. The valid period is a period in which the password can be used, and the valid number is a number in which the code number can be used. Details of the usage restriction information will be described later with reference to FIG. The server 6 automatically generates passwords for the number of visitors based on the input information, and returns the passwords to the accessed personal computers 8a to 8c.

  At the same time, the server 6 transmits the security code and the usage restriction information corresponding to the security code to the travel management control unit 3. The traffic management control unit 3 stores a personal identification number and use restriction information corresponding to the personal identification number in a personal identification number storage unit (not shown).

  As described above, the employee can easily obtain the visitor's personal identification number by his / her own operation by utilizing the server 6. Furthermore, the use restriction information set by the employee is stored in the personal identification number storage unit, and the visitor entrance / exit management based on the use restriction information can be realized. Here, in order to ensure security, it is desirable to require the login name and password to be input when the employee accesses the server 6. Also, if the automatically generated password and the login name of the employee who notified it are stored as a set, it is possible to track who made fraud from the history at a later date when there is unauthorized use.

  The employee notifies the visitor in advance of the personal identification number acquired from the server 6 by telephone or e-mail. A visitor can obtain admission permission by inputting the personal identification number notified in advance to the personal information setting units 2a to 2c at the time of the visit.

  The traffic management control unit 3 determines whether the personal identification number acquired from the personal information setting units 2a to 2c matches the personal identification number transmitted from the server 6 in advance, and is set corresponding to the personal identification number. Judge whether the usage restriction information is satisfied. When all the usage restriction information is satisfied, the traffic management control unit 3 unlocks the corresponding electric locks 4a to 4c and opens the doors 5a to 5c. Thereby, it is possible to enter a desired area based on the use restriction information.

  In the present embodiment, the personal identification information and the personal identification number are both identification information for performing traffic management control, but there are basically the following differences between the two. The personal identification information is written on the ID card 1 distributed to the employee, and although it has a valid period, there is no limit on the number of times it can be used, and it is possible to enter and exit the permitted location any number of times. On the other hand, the personal identification number is assigned to each visitor, and the validity period is individually set according to the visitor. In addition, by restricting the number of times the PIN can be used, the entrance / exit of visitors is restricted to ensure security. Rather than having a predetermined password for each door 5a-5c, a password is assigned to each visitor, and traffic management control is performed with additional usage restrictions.

  Furthermore, the present embodiment is provided with a first feature that according to the management area where entrance / exit management is performed, whether to use all digits of the password or whether to use some digits is used. In FIG. 2, for the door 5a, all areas of the toilet, the office B, and the office C correspond to the management area (hereinafter, the main management area A). On the other hand, only the office B in the main management area A corresponds to the management area (hereinafter referred to as sub management area B) for the door 5b, and only the office C in the main management area A for the door 5c. This corresponds to a management area (hereinafter referred to as sub-management area C).

  Therefore, in the door 5a of the main management area A corresponding to all areas, permission to enter / exit is determined based on all digits of the password. In the door 5b of the sub management area B after the door 5a is once opened and entered into the main management area A, permission of entry / exit is determined based on a part of the digits of the password. Similarly, also in the door 5c of the sub management area C after entering the main management area A, permission to enter / exit is determined based on some digits of the password.

  As described above, changing the number of digits of the personal identification number used for verification by the traffic management control unit 3 according to the management area has the following merit. When entering the main management area A, it is possible to prevent the visitor who does not know the password from entering and to improve the security by performing an input check using all digits of the password.

  On the other hand, when the visitor once enters the main management area A and then enters the sub management area B or sub management area C, it is after the input check at the door 5a has already been performed. Input check is performed only for some digits. This can reduce the number of digits of the password stored for verification. Further, in the sub management area B or the sub management area C, the same number can be assigned to a plurality of visitors as a part of the code number, and the storage capacity for storing the code number is further reduced. Can do.

  In order to distinguish between visitors who are permitted to enter / exit only the sub-management area B and visitors who are permitted to enter / exit only the sub-management area C, a part of the code number for performing the input check is used. Assign different numbers as digits. As a result, it is possible to easily prevent the visitor from entering or leaving the sub-management area where entry / exit is not permitted. Conversely, in order to allow a visitor to enter and exit both the sub-management area B and the sub-management area C, the number that can be used in common in both sub-management areas is the same as the PIN number for input check. By assigning them as a part of the digits, it is possible to easily manage entry / exit to both sub-management areas.

  Furthermore, changing the number of digits of the personal identification number used for verification by the traffic management control unit 3 according to the management area has the following merit in terms of the operation of the visitor. That is, when entering the main management area A, it is necessary to input all the digits of the password, but in the sub-management areas B and C where there is a possibility of entering and leaving the room several times, a part of the password is entered. You can easily enter and leave the room by entering only the digits.

  Furthermore, the present embodiment has a second feature in that the number of times the same password can be used is limited according to the management area where entrance / exit management is performed. For example, in the door 5a of the main management area A corresponding to all areas, the number of times the same password can be used is limited to one. It is assumed that the same personal identification number can be used any number of times in the door 5b of the sub management area B once the door 5a is opened and enters the main management area A. Similarly, the same personal identification number can be used any number of times in the door 5c of the sub management area C after entering the main management area A.

In this way, there is the following merit to restrict the number of uses of the password entered by the visitor according to the management area. When entering the main management area A, by restricting the code number so that it can be used only once, it is possible to prevent a plurality of visitors from entering with the same code number and to improve security. On the other hand, in the sub-management area, the visitor can go to the toilet or go to another sub-management area by limiting the number of times the PIN code entered by the visitor is used (or no limit). Can be re-entered after

  In addition, although the case where the set value is changed for each management area with respect to the number of effective times in the usage restriction information has been described, the set value can be changed for each management area with respect to the effective period. In this way, for example, in the management area of FIG. 2, the main management area A is continuously given a valid period of 4 days of entry / exit permission, and the sub management area B is given on the first and second days. For the sub-management area AC, the entrance / exit management with different effective periods for each sub-management area is possible, such as the third day and the second day for the sub-management area AC. Furthermore, in the present embodiment, the two layers of the main management area and the sub management area have been described, but the management area composed of three or more layers is also based on the use restriction information corresponding to the management area as described above. Entrance / exit management can be performed, and the same effect can be obtained.

  Here, the usage restriction information will be described in detail with reference to FIG. FIG. 3 is an explanatory diagram of the usage restriction information stored in the personal identification number storage unit according to Embodiment 1 of the present invention. As the usage restriction information, information on the valid period and the number of valid times is provided for each password. The validity period limits the period during which the PIN can be used. In FIG. 3, the valid period can be set separately for the year, month, day, time zone, and day of the week. Further, the valid number is the number of times that the personal identification number can be used, and the number of use is limited by the set value. The traffic management control unit 3 limits the number of times of use by adding up the number of times the password is used, updating the count value of the valid number, and comparing it with the set value of the valid number.

  For example, a visitor assigned with a personal identification number “11111111” in FIG. 3 is permitted to use the personal identification number only once during 24 hours on Friday, August 1, 2003. ing. Visitors who are assigned a personal identification number “222222222” are permitted to use the personal identification number only once a day on Saturdays and Sundays of September 1st, 2003 and between 8:00 and 20:00. It means that The count value of the effective number can be permitted to enter the next day by resetting the count value to 0 every day.

  The usage restriction information shown in FIG. 3 is for a certain management area. By having such use restriction information individually for each management area, the traffic management control unit 3 can realize the second feature described above based on the individual use restriction information corresponding to the management area. For example, in the main management area, the effective number is limited to one, but in the sub management area, the effective number can be set to 2 or more. The original usage restriction information is set individually by the employee from the personal computers 8a to 8c according to the visitors.

  Furthermore, the traffic management control unit 3 can realize the first feature described above based on the use restriction information for each management area stored in the personal identification number storage unit. In other words, depending on the management area where entrance / exit management is performed, it is possible to select whether to use all digits of the password or only some of the digits. Some digits to be used can be determined in advance for each management area or each hierarchy of management areas.

  Next, reading processing of personal identification information and decoding processing of a personal identification number by the personal information setting units 2a to 2c will be described with reference to FIGS. FIG. 4 is a configuration diagram of the personal information setting unit according to Embodiment 1 of the present invention. FIG. 5 is a flowchart showing the flow of the personal identification information reading process and the personal identification number decoding process in the first embodiment of the present invention. In FIG. 4, as a representative example of the personal information setting units 2a to 2c, description will be made using reference numerals without the subscripts a to c. In FIG. 5, the portion surrounded by the alternate long and short dash line indicates processing in the traffic management control unit 3.

  The personal information setting unit 2 in FIG. 4 has both an ID card reading unit 10 corresponding to a personal information reading unit and a personal identification number input unit 9. Here, the personal identification number input unit 9 has two functions as means for reading the personal identification number. The first means is a numerical value input means for inputting the personal identification number with the numeric keypad 11, and the second means is an image input means for inputting the personal identification number as an image from the camera 15.

  First, it is determined whether the numeric keypad 13 has been pressed (S501). If the numeric keypad 13 is pressed, it is determined that the code number is input by the key input means, and the input from the numeric keypad 11 is read as the code number (S502). On the other hand, if the numeric keypad 13 is not pressed in step S501, it is determined whether the camera button 12 is pressed (S503). If the camera button 12 is pressed, it is determined that the password has been input by the image input means, and the password is read from the camera 15 (S504).

  If the camera button 12 has not been pressed in step S503, it is determined whether the ID card 1 has been read (S505). An employee holding the ID card 1 can read the personal identification information in the ID card 1 by holding the ID card over the ID card reading unit 10.

  If the ID card 1 cannot be read in step S505, the process returns to step S501 and waits for a new input. On the other hand, when the ID card 1 is read in step S505, the personal information setting unit 2 reads the personal identification information in the ID card 1 (S506). Further, the read personal identification information is sent to the travel management control unit 3 (S507).

  The traffic management control unit 3 determines whether the personal identification information sent from the personal information setting unit 2 matches the personal identification number already registered in the personal identification information storage unit in order to permit the traffic ( S508). If they match, the doors (corresponding to the doors 5a to 5c in FIG. 1) are opened for a certain period of time by unlocking the electric locks (corresponding to the electric locks 4a to 4c in FIG. 1) (S509). On the other hand, if they do not match, the process returns to step number S501 without performing the unlocking process and waits for a new input.

  Next, the subsequent processing when the personal identification number is read in step number S502 or step number S504 will be described. When the personal information setting unit 2 reads the input of the personal identification number from the visitor (S502 or S504), the personal information setting unit 2 sends the input personal identification number information to the travel management control unit 3 (S510).

  When the traffic management control unit 3 receives the password, it determines the installation location of the personal information setting unit 2 (2a to 2c) that is the transmission source, and identifies whether the area to be managed is the main management area or the sub management area ( S511). If it is determined in step S511 that the area is the main management area, it is determined whether all the digits of the input password are the same (S512). If they do not match, the process returns to step S501 to wait for a new input.

  If all the digits of the code number match in step S512, it is further determined whether the entered code number is within the validity period and whether this code number is used for the first time. (S513). That is, based on the data stored in the personal identification number storage unit, the usage restriction information regarding the corresponding main management area is checked. If any of the conditions is not satisfied, the process returns to step number S501 and waits for a new input. Here, the limit on the number of times of use is one time, but it is also possible to set two or more times depending on the application.

  When these two conditions are satisfied at step S513, the traffic management control unit 3 unlocks the electric lock (corresponding to the electric locks 4a to 4c in FIG. 1), thereby opening the door (the door 5a in FIG. 1). (Corresponding to ˜5c) is opened for a certain time (S509). As a result, it is possible to enter and leave the main management area.

  On the other hand, if it is determined at step number S511 that it is a sub-management area, it is determined whether some digits of the input personal identification number match (S514). If they do not match, the process returns to step S501 to wait for a new input.

  If part of the digits of the personal identification number matches in step S514, it is further determined whether the inputted personal identification number is within the valid period and the valid number of times (S515). That is, the usage restriction information is checked based on the data of the corresponding main management area stored in the personal identification number storage unit. In step S515, the area to be managed is a sub-management area, and the number of valid passwords can be set to two or more, thereby allowing multiple entry / exit. When the condition is not satisfied in step S515, the process returns to step S501 and waits for a new input.

  When the condition is satisfied in step S515, the traffic management control unit 3 unlocks the electric lock (corresponding to the electric locks 4a to 4c in FIG. 1), thereby opening the door (to the doors 5a to 5c in FIG. 1). Corresponding) is opened for a certain time (S509). As a result, it is possible to enter and leave the sub management area. Although the usage restriction information is checked in step S515, since the usage restriction information has already been checked in the main management area, it is possible to omit the usage restriction information check in the sub management area. is there.

  According to the first embodiment, the visitor can enter and leave the room without the processing at the reception by using the personal identification number notified in advance. By restricting the number of times the password is used, it is possible to prevent a plurality of visitors from entering with the same password in the main management area, thereby improving security. On the other hand, in the sub-management area, the visitor can go to the toilet or go to another sub-management area by limiting the number of times the PIN code entered by the visitor is used (or no limit). Re-entry is permitted. Furthermore, by changing the number of digits of the password used for collation according to the management area, it is possible to improve the operability of the visitor and prevent the visitor who does not know the password from entering. Furthermore, it is possible to prevent entry / exit outside the effective period by providing an effective period as the use restriction information corresponding to the personal identification number.

Embodiment 2. FIG.
In the first embodiment, the case where the employee obtains the personal identification number by accessing the server 6 in advance has been described. In the second embodiment, a new password is registered based on a simple operation from the personal information setting unit 2 without the server 6, and will be described with reference to FIG. 1 to 4 used in the description of the first embodiment are commonly used in the second embodiment, but the description thereof is omitted. FIG. 6 is a flowchart showing the flow of the personal identification information reading process, the personal identification number decoding process, and the registration process according to the second embodiment of the present invention.

  Step numbers S501 to S515 in FIG. 6 are the same as step numbers S501 to S515 in FIG. The process of performing simple registration of a personal identification number is described in step numbers S601 to S605, and will be described in detail below.

  If the camera button 12 has not been pressed in step S503, it is determined whether the registration button 14 has been pressed (S601). Here, the registration button 14 corresponds to registration mode switching means. If the registration button 14 has not been pressed, the processing after step number S505 is performed in the same manner as in the first embodiment.

  When the registration button 14 is pressed in step S601, the personal information setting unit 2 enters the registration mode for a certain period of time. Furthermore, the personal information setting unit 2 determines whether specific personal identification information has been read from the ID card reading unit 10 in the registration mode (S602). If a new password can be set simply by pressing the registration button 14, anyone can register a new password and enter or leave the room, and security is lowered. Therefore, in the present embodiment, as a specific operation after the registration button 14 is pressed, input for registering a new personal identification number is permitted for the first time by reading specific personal identification information. When a specific operation is not performed at step number S602 (that is, when specific personal identification information is not read), the process returns to step number S501 and waits for a new input.

The specific operation in the registration mode is, for example, as follows.
1) When the ID card 1 of two or more employees is continuously read by the ID card reading unit 10.
2) When the ID card reading unit 10 reads the ID card 1 including the personal identification information of the person in charge of entering and leaving the room.

  In the method 1), the use of ID cards 1 of two or more employees has an effect of preventing unauthorized use. In the method 2), since a new password can be registered only by using the ID card 1 of the manager in charge, security is maintained. If it is determined in step S602 that the specific operation has been performed (that is, the specific personal identification information has been read), the input of the password by the numeric keypad 11 is accepted (S603). Furthermore, the personal information setting unit 2 transmits the entered password to the bank management control unit 3 (S604). The traffic management control unit 3 registers the personal identification number received from the personal information setting unit 2 in the storage unit as a new personal identification number for permitting admission (S605).

  In the second embodiment, only a new password is registered based on a simple operation from the personal information setting unit 2, and no usage restriction information is set. However, the use restriction information can be set in advance for a password newly registered from the personal information setting unit 2. For example, the valid period is uniform and valid only for one day, and the default number of times for the main management area and the sub management area for the effective number of times is one, so that the entrance / exit management taking into account usage restriction information can be performed. realizable.

  According to the second embodiment, a new password can be registered based on a simple operation from the personal information setting unit 2 without the server 6 by such a series of operations. Furthermore, registration of a new password is permitted based on a specific operation, and security can be ensured. Furthermore, entrance / exit management can be performed based on predetermined use restriction information.

  In the first and second embodiments, the case where a personal identification number is used as the personal identification code has been described. However, as the personal identification code, a character code such as an alphabet can also be used in addition to numerals.
