Embodiment 1
FIG. 1 is a block diagram of an entry and exit management system according to a first embodiment of the present invention.
In FIG. 1, 1 is a management area such as a building. The user of the management area 1 carries the authentication medium 2. The authentication medium 2 comprises a portable magnetic recording member and a memory. A unique card ID number is stored in the authentication medium 2 as personal identification information for identifying an identification target. The authentication medium 2 may store a unique user ID, a personal identification number, a user's date of birth, an expiration date, etc. as personal identification information.

The management area 1 is divided into a plurality of management areas (not shown). Each control area is provided with an entrance (not shown). Each entrance is provided with a door (not shown). Each door is provided with an electric lock (not shown). In the vicinity of each entrance and exit, an authentication terminal 3 is provided corresponding to each electric lock. Each authentication terminal 3 is connected to the management device 5 via the communication network 4.

Next, the authentication terminal 3 will be specifically described.
The authentication terminal 3 includes a terminal I / F unit 3a, a communication I / F unit 3b, an electric lock I / F unit 3c, a storage unit 3d, and a terminal control unit 3e.

The terminal I / F unit 3 a has a function of reading personal identification information from the authentication medium 2. The communication I / F unit 3 b has a function of communicating with the outside via the communication network 4. The electric lock I / F unit 3c has a function of controlling the associated electric lock. The storage unit 3 d has a function of storing a program for entry and exit management. The terminal control unit 3e has a function of performing entry and exit management by reading and executing the program of the storage unit 3d.

Next, the management device 5 will be specifically described.
The management device 5 comprises a computer such as a server or a personal computer. The management device 5 includes a communication I / F unit 5a, an operation input unit 5b, a screen display unit 5c, a storage unit 5d, and a management control unit 5e.

The communication I / F unit 5 a has a function of communicating with the outside via the communication network 4. The operation input unit 5b includes a keyboard, a mouse and the like. The screen display unit 5c comprises a display device such as a CRT or an LCD. The screen display unit 5c has a function of displaying various information necessary for entry and exit management and an unauthorized operation occurrence alarm when an unauthorized operation (illegal passage) is detected.

The storage unit 5d functions as a storage unit that stores various data used in various processes. Specifically, the storage unit 5d stores the traveling time table 5f and the operation history table 5g. The movement time table 5 f stores a reference time for movement between the authentication terminals 3. In the operation history table 5g, the ID of the authentication terminal 3 that has performed the operation and the operation time are stored in association with each other for each user ID of the personal identification information.

The management control unit 5e has a function of performing various processes related to entry and exit of each management area. Specifically, the management control means 5e functions as an authentication means for authenticating the user based on the travel time table 5f and the operation history table 5g.

Next, the basic operation of the room access control system will be described.
First, the case where the user enters the management area 1 for the first time and the case where the system is reset will be described. In this case, the user holds the authentication medium 2 over the terminal I / F unit 3a of the authentication terminal 3 corresponding to any of the control areas. The terminal I / F unit 3a of the authentication terminal 3 reads personal identification information from the authentication terminal 3.

The personal identification information read is transmitted to the communication I / F unit 5 a of the management device 5 via the communication I / F unit 3 b of the authentication terminal 3 and the communication network 4. The storage unit 5d of the management device 5 stores the ID of the operated authentication terminal 3 and the operation time (identification time) in the operation history table 5g in association with the user ID of the transmitted personal identification information.

Thereafter, the user moves to another management area, and holds the authentication medium 2 over the terminal I / F unit 3a of the authentication terminal 3 corresponding to the management area of the movement destination. The terminal I / F unit 3a of the authentication terminal 3 of the movement destination reads the personal identification information from the authentication medium 2. The personal identification information thus read is transmitted to the communication I / F unit 5 a of the management apparatus 5 via the communication I / F unit 3 b of the authentication terminal 3 of the moving destination and the communication network 4.

The management control unit 5e of the management device 5 receives an operation notification from the authentication terminal 3 of the movement destination via the communication I / F unit 5a. Thereafter, based on the user ID of the personal identification information, the management control unit 5e of the management device 5 acquires the ID of the authentication terminal 3 operated immediately before by the user as the ID of the movement source authentication terminal 3, The operation time at the movement source authentication terminal 3 is also acquired.

After that, the management control unit 5e of the management device 5 uses the operation time at the move source authentication terminal 3 and the operation time at the move destination authentication terminal 3 to set the time difference between the operations at both authentication terminals 3 as the estimated movement time. calculate.

After that, the management control unit 5e of the management device 5 refers to the moving time table 5f based on the ID of the moving source authenticating terminal 3 and the ID of the moving destination authenticating terminal 3, and the reference time between both the authenticating terminals 3 get. Thereafter, the management control unit 5e of the management device 5 compares the estimated movement time with the reference time.

For example, if the estimated movement time is shorter than the reference time, it means that the user has moved between both authentication terminals 3 in a time shorter than the reference time. This move is not realistic. Therefore, the management control unit 5e of the management device 5 determines that there is an unauthorized operation. In this case, the electric lock in the control area of the movement destination is not unlocked. This prevents unauthorized entry into the managed area to the destination.

As described above, it is necessary to register the reference time in the movement time table 5 f in association with the IDs of the authentication terminal 3 of the movement source and the movement destination. In order to register this reference time in advance, it is necessary to measure in advance the moving time required to move between the authentication terminals 3. Therefore, when the number of the authentication terminals 3 is large, when the arrangement of the authentication terminals 3 is changed, and when the authentication terminal 3 is newly added, the effort for registering the reference time is very large.

Therefore, in the present embodiment, the management apparatus 5 is provided with moving time table creation changing means (updating means) 5h, and based on the statistical value of the difference in the identification time of each user ID at different authentication terminals 3 I updated the time. Hereinafter, the method of updating the reference time will be described.

First, the travel time table 5f of the present embodiment will be described using FIG.
FIG. 2 is a diagram for explaining a moving time table of the entry and exit management system according to the first embodiment of the present invention.

As shown in FIG. 2, in the transfer time table 5f, the ID of the authentication terminal 3 of the transfer source is associated with the ID of the authentication terminal 3 of the transfer destination. A pointer value is also associated with these associations. A difference between recognition times of the authentication terminal 3 at the movement source and the authentication terminal 3 at the movement destination is stored as an actual measurement value corresponding to these pointer values.

The moving time table creation changing means 5h calculates statistical values of these actual measured values. Specifically, moving averages, standard deviations, and coefficients of variation are calculated as statistical values. These statistical values are stored in the moving time table 5f in association with the authentication terminal 3 of the movement source and the authentication terminal 3 of the movement destination.

As an example, the case where the first terminal is a movement source and the second terminal is a movement destination will be described. In this case, the actual measurement values corresponding to the respective pointer values are "300" (seconds), ... "308" (seconds). The average at this time is 303.0 (seconds). The standard deviation at this time is 16.6. The coefficient of variation at this time is 5.48.

Next, the method of calculating the statistical value will be specifically described with reference to FIG.
FIG. 3 is a flow chart for explaining the operation of the room entry and exit management system according to the first embodiment of the present invention.

First, in step S1, the travel time table creation / change unit 5h receives an operation notification via the communication I / F unit 5a of the management apparatus 5 and the management control unit 5e. Thereafter, the moving time table creation changing means 5h acquires the user ID in the operation notification and the ID of the authentication terminal 3, and stores the ID of the authentication terminal 3 as the ID of the movement destination authentication terminal 3 of the user. Thereafter, the process proceeds to step S2, and the moving time table creation changing means 5h determines whether or not there is a history before the received user ID in the operation history table 5g.

If there is no history before the received user ID, the moving time table creation changing means 5h ends the operation. If there is a history before the received user ID, the process proceeds to step S3. In step S3, the moving time table creation changing means 5h acquires the ID of the authentication terminal 3 at that time, and stores it as the ID of the movement source authentication terminal 3.

Thereafter, the process proceeds to step S4, and the moving time table creation changing means 5h calculates the moving time by calculating the difference between the operation time at the moving source authentication terminal 3 and the operation time at the moving destination authentication terminal 3. Thereafter, the process proceeds to step S5, and the moving time table creation changing means 5h refers to the pointer value of the row to which the ID of the moving source authenticating terminal 3 and the ID of the moving destination authenticating terminal 3 in the moving time table 5f respectively correspond.

Thereafter, the process proceeds to step S6, the moving time table creation changing means 5h changes the value of the column corresponding to the pointer value by the actual measurement value of the corresponding row of the moving time table 5f to the calculated moving time. Thereafter, the process proceeds to step S7, and the moving time table creation changing means 5h performs a pointer value update process. Specifically, the moving time table creation changing means 5h determines whether the referred pointer value is smaller than N or not.

If the pointer value is smaller than N, the process proceeds to step S8. In step S8, the moving time table creation changing means 5h increases the pointer value by one. Thereafter, the process proceeds to step 9, and the moving time table creation changing means 5h updates the pointer value of the corresponding line of the moving time table 5f. Thereafter, the process proceeds to step S10, the moving time table creation changing means 5h recalculates the moving average, the standard deviation and the variation coefficient as statistical values, and stores the calculation result in the corresponding line of the moving time table 5f.

On the other hand, if the pointer value referred to in step S7 is N, the process proceeds to step S11. In step S11, the moving time table creation changing means 5h sets the pointer value to 1. Thereafter, the process proceeds to step S9, and the moving time table creation changing means 5h returns the pointer value of the corresponding line of the moving time table 5f to 1. Thereafter, the process proceeds to step S10, the moving time table creation changing means 5h recalculates the moving average, the standard deviation and the variation coefficient as statistical values, and stores the calculation result in the corresponding line of the moving time table 5f.

These operations are performed each time each user operates each authentication terminal 3. For this reason, every time different authentication terminals 3 successively identify the identification target, the movement time table 5 f stores the difference in the identification time between the corresponding authentication terminals 3.

Next, an example of a method of setting the reference time will be described.
In the present embodiment, a value of average value−standard deviation × 3 is set as the minimum moving time. On the other hand, a value of average value + standard deviation × 3 is set as the maximum moving time. The minimum travel time and the maximum travel time are calculated corresponding to each combination of the authentication terminal 3 of the movement source and the authentication terminal 3 of the movement destination. These calculation results are stored in the movement time table 5f in association with each combination of the authentication terminal 3 of the movement source and the authentication terminal 3 of the movement destination.

Based on the reference time set in this way, the management control unit 5e of the management device 5 determines whether or not an unauthorized operation has been performed. Specifically, the management control unit 5e of the management device 5 determines that there is an unauthorized operation when the calculated movement time is shorter than the minimum movement time or longer than the maximum movement time.

According to the first embodiment described above, the reference time corresponding to the actual movement time is automatically set based on the statistical value of the difference in the identification time of the authentication terminal 3. For this reason, it can be unnecessary to measure the movement time between the authentication terminals 3 in advance. Moreover, when the arrangement of the authentication terminal 3 is changed, there is no need to measure the reference time again. Furthermore, the reference time is updated. Therefore, the accuracy of the reference time can be improved.

If it is determined that the movement time is incorrect, the movement time may not be stored in the movement time table 5f. In this case, singular values can be excluded from the population when obtaining the statistical value. As a result, the accuracy of the statistical values in the moving time table 5f is improved. Therefore, it is possible to further improve the accuracy of entering and leaving management.

Also, statistical values may be calculated for each user, for each gender, for each age, for each user attribute such as wheelchair user, etc. In this case, it is possible to set a reference time that matches the user's attribute. At this time, when setting the minimum moving time, the statistical value of the attribute of the user assumed to have a high moving speed is used, and when setting the maximum moving time, the attribute of a user assumed to have a low moving speed By using the statistical value of, it is possible to more reliably prevent unauthorized entry into the control area.

Further, in the first embodiment, the reference time is set using N moving averages to simplify the calculation. However, the reference time may be set using a simple arithmetic mean. Also in this case, the same effect as that of the first embodiment can be obtained.

In addition, until N actual measurement values of the operation time difference between the authentication terminals 3 are aligned, one of the actual measurement values may be copied to be another actual measurement value. In this case, entry and exit can be managed with a certain degree of accuracy from the beginning of the introduction of the system. On the other hand, if the judgment of the unauthorized operation is inhibited until N actual measurement values of the difference in operation time between the authentication terminals 3 are aligned, the probability of erroneously determining the unauthorized operation can be lowered.

Further, the setting of the reference time may be changed in consideration of the arrangement of each authentication terminal 3. For example, when moving between controlled areas facing a straight path, in principle, you will move on foot. For this reason, the variation in travel time between controlled areas is considered to be relatively small. In this case, the difference between the minimum travel time and the maximum travel time may be set relatively small. On the other hand, when moving between control areas on different floors, stairs, escalators, elevators, etc. can be considered as means of movement. In this case, the variation in travel time between controlled areas is considered to be relatively large. In this case, the difference between the minimum travel time and the maximum travel time may be set relatively large. In these cases, it is possible to set a reference time suitable for the arrangement of each authentication terminal 3.

In addition, biometric identification may be used to identify an identification target. Also in this case, the same effect as that of the first embodiment can be obtained.

Second Embodiment
FIG. 4 is a block diagram of a room entry and exit management system according to a second embodiment of the present invention. The same or corresponding portions as in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

The management apparatus 5 according to the second embodiment is the management apparatus 5 according to the first embodiment to which the unauthorized passage determination means 5i is added. Whether or not to determine the unauthorized operation (illegal passage) using the reference time with reference to an index (for example, a variation coefficient) indicating the variation of the difference in identification time between the authentication terminal 3 whether or not the unauthorized passage determination means 5i Have the function of determining Specifically, the illegal passage determination unit 5i functions as a prohibiting unit that prohibits the determination of the unauthorized operation based on the statistical value when the referred index is larger than a predetermined determination reference value.

According to the second embodiment described above, the management device 5 determines the unauthorized operation only between the authentication terminals 3 having a small variation in difference in identification time. Therefore, it is possible to reduce the probability of misjudgment of the illegal operation.

In addition, among the authentication terminals 3 having a large variation in identification time, the minimum value of the actual measurement values corresponding to the authentication terminals 3 is set as the minimum moving time, and the maximum value of the actual measurement values corresponding to the authentication terminals 3 Should be set to the maximum travel time. In this case, it is possible to manage entering / leaving with a certain degree of accuracy even between authentication terminals 3 having a large variation in identification time difference.

As described above, the entry and exit management apparatus according to the present invention and the entry and exit management system using the same can be used for an entry and exit management apparatus and system.
