Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reading characteristic point data of a human body and controlling passage permission at a predetermined place.

[0002]

2. Description of the Related Art In order to prevent persons other than those concerned from entering a specific area of a building, a door that can be opened and closed by an electric lock is provided at the passage or entrance to the specific area, and a door to the specific area is opened near this door. In some cases, a personal identification device for determining whether or not a person is permitted to pass is installed. As this personal identification device,
For example, as shown in Japanese Patent Laid-Open No. 61-255639, there is a device in which a fingerprint is detected to identify an individual.

This is because a fingerprint of a predetermined finger is picked up, density of the screen is converted into an electric signal, fingerprint information is output, and this is collated with pre-registered fingerprint information to see if they match. , Or whether there is a disagreement.
Then, when the door is closed, if the coincidence of the fingerprint information is determined, an unlock signal is output to the electric lock, and if the mismatch of the fingerprint information is determined, the unlock signal is not output.

There is also a method of using an identification card (hereinafter referred to as an ID card) such as an IC card or an optical card for registering fingerprint information. In this method, fingerprint information is registered in an ID card, and the fingerprint information input at the time of fingerprint collation and the registered fingerprint information are collated to determine whether they match or not. There are a contact type and a non-contact type for reading and writing information on the ID card. Characteristic points of the human body other than the fingerprint, such as voiceprint, face shape, retina, finger length, palm shape, handwriting, etc., are also used as the discrimination information.

[0005]

In the conventional traffic control device as described above, since the inputted human body information is collated with the registered human body information, there are few characteristic points of the human body (fingerprint. In this case, the collation result may be difficult to obtain when the fingerprint is light). Such a person may be judged to be inconsistent in the collation, and it is necessary to perform the collation operation many times, resulting in a long passage time and annoying the passerby.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a traffic control device capable of completing verification of human body information reliably and in a short time even when the human body information is unclear. To aim.

[0007]

The traffic control device according to the first aspect of the present invention collates the read characteristic point data of the human body with previously registered characteristic point data of the human body, and both are coincident with each other. In a device for judging whether or not a passage is permitted at a predetermined place, a passage count recording means for recording the number of passages and a reference change for lowering the coincidence determination criterion of feature point data when the passage count exceeds a predetermined number And means.

The traffic control device according to the second aspect of the invention is the traffic control device according to the first aspect of the invention, in which characteristic point data of a human body is registered,
In addition, an identification card is provided for recording the number of times of passage and reading this information at the time of matching the characteristic point data.

A traffic control device according to a third aspect of the invention is a traffic frequency recording means of the first invention, a difficulty level storage means for storing the difficulty level of determination of feature point matching of a human body, and a traffic frequency of a predetermined number or more. In the case of, the matching determination standard of the feature point data is lowered and the matching is performed, and when the result of the matching of the characteristic points of the human body is not matched, the matching determination criterion of the feature point data is lowered and the matching is performed according to the stored difficulty level. And are provided.

The traffic control device according to the fourth aspect of the present invention is the traffic control device according to any one of the first to third aspects of the invention, which stores personal information of a person including characteristic points data and history of the human body of the passerby. And a personal information display means for displaying the stored personal information when the result of the feature point comparison is still inconsistent even if the matching determination criterion of the feature points of the human body is lowered.

Further, in addition to the traffic control device according to the fourth invention, the traffic control device according to the fifth invention adds the number of traffic recorded when a traffic permission signal is input by an artificial operation after the operation of the personal information display means. The means for adding the number of passages is provided.

In the traffic control device according to the sixth aspect of the present invention, in the first to fifth aspects of the invention, a fingerprint reader is used as a device for reading the characteristic point data of the human body. Or, it is configured to be incorporated in a portion to be operated.

[0013]

In the first aspect of the present invention, when the number of times of passage exceeds a predetermined number of times, the matching criterion of the characteristic point data is lowered and the matching is performed. Therefore, the characteristic point data of the human body is correct according to the lowered criterion. Is judged.

Further, in the second aspect of the invention, since the feature point data of the human body is registered in the identification card and the number of times of passing is recorded, it is not necessary to store these data on the device side.

Further, in the third aspect of the invention, when the number of passages is a predetermined number of times or more, the feature point data matching criterion is lowered to perform the matching, and when the feature point matching results do not match, the feature point matching determination is performed. Since the matching criterion is lowered according to the degree of difficulty and the matching is performed, the feature point data of the human body is judged to be correct according to the lowered criterion.

Further, in the fourth aspect of the invention, even if the matching judgment criterion of the characteristic points of the human body is lowered and the matching is performed, the personal information of the passerby is displayed when the result of the characteristic point matching does not match. The clerk can judge whether the human body verification is correct or not by looking at the displayed personal information.

Further, in the fifth aspect of the invention, when the passage permission signal is artificially input after the personal information is displayed, the number of passages is added, so that the number of passages due to human judgment is also added once.

FIG. 3 is a block diagram, FIG. 3 is an operation flowchart of the first controller, FIG. 4 is an operation flowchart of the second controller, and the same reference numerals indicate the same parts.

In FIG. 1, (1A) and (1B) are doors provided at doorways, (2) is an electric lock that electrically locks and unlocks the door (1A), and (3A) is a door (1A). The first controller installed in the vicinity to control the electric lock (2) by collating the fingerprints of passersby, the (3B) is installed in the vicinity of the door (1B) and operated by the judgment of the attendant (4). It is a controller.

In FIG. 2, (6) is the CPU and (7) is the RO
M, (8) is RAM, (9) is a card reader / writer that reads data stored in an ID card carried by a passerby or stores data in the ID card, and (10) is a passerby puts a finger on the card. And a fingerprint reader for reading the fingerprint, and (11) is an A / D converter which is connected to the fingerprint reader (10) and converts the characteristic point data of the analog fingerprint to a digital value. (12) is an OK / NG display for displaying the fingerprint matching result, and (13) is an electric lock.
It is an interface connected to (2) and each of the above devices (6)
~ (13) are connected to each other by a bus (14).

(16) CPU, (17) ROM, (18) RA
M, (19) is a card reader / writer similar to the card reader / writer (9), (20) is a liquid crystal display for displaying personal information (described later), and (21) is determined by the attendant (4) to allow passage. This is an OK switch to be operated, and the above devices (16) to (21) are connected to each other by a bus (22).

Next, the operation of the first controller (3A) of the first embodiment will be described with reference to FIG. The program of this flowchart is stored in the ROM (7). In addition, ID
It is assumed that the card stores an ID number, fingerprint feature point data, and the number of passes. First, in step (31), the card reader / writer (9) stores the I stored in the ID card.
Wait for reading the D number, fingerprint feature point data, and the number of passes. After reading each of the above data, in step (32) I
It is judged whether the D number is positive, and if not, the step (33)
Then, "NG" is temporarily displayed on the OK / NG display (12) and the process returns to step (31).

If the ID number is positive, step (34) is OK.
/ NG display (12) temporarily displays "OK" and proceeds to step (35). Then, in step (35), the fingerprint reader (1
Wait for your finger to be placed at 0). When your finger is placed, step
At (36), the image analog signal of the fingerprint reader (10) is converted into a digital signal by the A / D converter (11), and at step (37), the characteristic points of the fingerprint are calculated. In step (38), the fingerprint feature point data calculated above is collated with the fingerprint feature point data read from the ID card, and it is determined whether the two match within the first predetermined range.

If the above collation results match, step (39)
Then, "OK" is displayed on the OK / NG display (12) in a blinking manner at a time, and the process proceeds to step (40). Then, in step (40), it is judged whether or not the number of traffic read in step (31) is N times, and if it is N times, an unlock signal is output to the electric lock (2) in step (41). Temporarily unlock the door (1A). Now passers-by can open the door (1A) to enter. If the number of traffic is not N, go from step (40) to step (42).
Then, the number of passages is incremented by 1 and written in the ID card through the card reader / writer (9), and the electric lock (2) is temporarily unlocked in step (41), and the process ends.

If it is determined in step (38) that the collation results do not match, the process proceeds to step (43), and it is determined in step (31) whether or not the number of passages read is N or more. For example, in step (44), the fingerprint feature point data calculated above is collated with the fingerprint feature point data read from the ID card, and both are within a second predetermined range wider (loose) than the first predetermined range. Determine if they match. If the collation results match, "OK" is displayed on the OK / NG display (12) in step (45).
Is temporarily blinked, the electric lock (2) is temporarily unlocked in step (41), and the process ends. If the collation results do not match, in step (46), the OK / NG display (12) temporarily blinks "NG" and the process ends.

The passer-by indicated by "NG" in step (46) goes to the door (1B) and is re-verified in the presence of the attendant (4). Here, the step (42) constitutes a passage count recording means, and the steps (43) and (44) constitute a reference changing means.

Next, the operation of the second controller (3B) will be described with reference to FIG. The program of this flowchart is stored in the ROM (17). First, in step (51), the card reader / writer (19) waits for the number of passages stored in the ID card (personal information storage means) and the personal information of the person to be read. Here, personal information includes nationality, age,
Gender, date of birth, height, facial contour, facial features (eyes, mouth,
The information is peculiar to an individual such as nose, ear, etc.) and other information only known to the person (for example, date of marriage).

Then, in step (52), the read personal information is displayed on the liquid crystal display (20). The clerk (4) observes the passers-by while viewing the displayed personal information, and judges the pass-through permission based on the question and answer. When it is determined that the passage is permitted, the OK switch (21) is operated. O in step (53)
It is judged whether or not the K switch (21) is operated to input the passage permission signal. If it is input, the number of passages is set to 1 in step (54).
Only increase the number and write to the ID card through the card reader / writer (19). However, when it is N times, it is kept N times. Then, in step (55), the personal information on the liquid crystal display (20) is erased and the process ends. Now the passerby is the door (1B)
You will open and enter.

When the clerk judges that the passage is not permitted, the OK switch (21) is not operated, so the process proceeds from step (53) to step (56) to erase the personal information on the liquid crystal display (20) after a predetermined time. After that, the clerk (4) guides the unauthorized person to another room in order to investigate whether there is any illegal traffic. Here, the step (52) constitutes a personal information display means, and the step (54) constitutes a passage count addition means.

In this way, the fact that the number of passes is large is
Since it means that the number of times of passage permission has been increased, the matching criterion of the fingerprint feature point data is lowered to facilitate the collation, and the processing time is shortened so that the passage can be performed faster. In the case of collation mismatch, the clerk (4) will judge, but at this time, the personal information is displayed to lighten the burden on the clerk (4). Further, since the fingerprint is stored in the ID card, it is suitable for processing a large number of people.

Example 2. FIG. 5 is a diagram showing an embodiment of the third invention of the present invention, and is a partial view of the operation flowchart of FIG. Note that FIGS. 1, 2, and 4 are also used in the second embodiment. In the second embodiment, step (48) is added to FIG. In the second embodiment, the difficulty level of distinguishing the characteristic points of the fingerprint is divided into several ranks, and the difficulty level of the fingerprint at the time of registering the fingerprint is
The difficulty storage means (not shown) writes the ID card. The degree of difficulty is set to high rank (easy to collate) when the amount of feature point data is large, and low rank (difficult to collate) when the amount of characteristic point data is small.

At the time of fingerprint collation, the number of passages is N in step (43).
If it is judged to be less than the number of times, in step (48) the matching criterion is changed according to the rank of the above-mentioned difficulty level and re-matching is carried out. If they match, in step (45) the OK / NG display (12) is displayed. Blinks "OK" on the display for a moment, and then proceed to step (41) to turn on the electric lock.
Temporarily unlock (2). If they still do not match, the routine proceeds to step (46), where "NG" is temporarily blinked and displayed on the OK / NG indicator (12), and the processing is terminated. Where step (43)
(44) and (48) constitute standard changing means.

In this way, even a person with a light fingerprint and few feature points can be collated with a lower criterion, so that a correct result can be obtained, and an opportunity to seek the attendance of a clerk at each collation mismatch. It becomes possible to reduce.

Example 3. Embodiment 3 shows one embodiment of the sixth invention of the present invention, and although not shown in particular, the fingerprint reader (10) is used as a knob of the door (1A), a horizontal bar of a revolving door (not shown), etc. It is built in. In this case, since the fingerprint reader (10) is normally located at a portion to be touched or operated without requiring a passerby to perform a special operation,
It is not necessary to inform the passerby that the fingerprint discrimination is being performed, and it is possible to prevent the passerby from feeling useless caution.

Other Embodiments. In addition to the above embodiments, the following implementations are possible. (1) Instead of writing the number of times of passing on the ID card, another counter (not shown) provided on the side of the first and second controllers (3A) and (3B) is used for counting. (2) A door without an attendant (4), for example, the first controller (3A) of the door (1A) of FIG. 1, is also provided with a liquid crystal display or the like to display personal information. Then, when the collation does not match, the clerk (4) can judge by looking at the personal information. Also, the personal information can be displayed on all the doors (1A) (1B) regardless of the presence or absence of the attendant (4).

(3) First and second doors on all doors (1A) (1B)
Only one of the controllers (3A) and (3B) is provided. (4) A magnetic card, an IC card, an optical card, a holography card, or the like is used as the ID card. (5) Doors should be applied to all gates such as normal manual doors, automatic doors and revolving doors. (6) Not only fingerprints but also voiceprints, retinas, finger lengths, palm shapes, handwritings, face shapes, weights, etc. are used as data for human body verification. Also, by using these together, if any of them is positive, it is determined that the collation matches. (7) Instead of using an IC card, enter the password with a numeric keypad. Also, both are used together.

[0038]

As described above, according to the first aspect of the present invention, when the number of times of passage exceeds a predetermined number of times, the matching judgment criterion of the feature point data is lowered and collation is performed, so that the feature point data of the human body is lowered. Whether or not it is correct is determined based on the determined criterion, and there is an effect that the processing time of a passerby who has been permitted to pass many times can be shortened and the passerby can be made to pass earlier.

Further, in the second aspect of the invention, since the feature point data of the human body is registered in the identification card and the number of times of passing is recorded, it is not necessary to store these data on the side of the device, and it is possible for a large number of people to store the data. There is an effect that it can be made suitable for processing.

According to the third aspect of the invention, when the number of times of passage is a predetermined number of times or more, the matching judgment criterion of the characteristic point data is lowered to perform the matching, and when the result of the characteristic point matching does not match, the determination of the characteristic point matching is difficult. Since the matching criterion is lowered according to the degree of matching, the feature point data of the human body is judged to be right or wrong according to the lowered criterion, and it is possible to reduce the chance of requiring the attendant to be present at each matching mismatch. There is an effect.

Further, in the fourth aspect of the present invention, even if the matching judgment criterion of the characteristic points of the human body is lowered and matching is performed, the personal information of the passerby is displayed when the result of the characteristic point matching does not match. The clerk can judge whether the human body verification is correct or not by looking at the displayed personal information, which facilitates the clerk's determination and reduces the trouble that the passage is not permitted even though the human body verification is correct. is there.

Further, in the fifth aspect of the invention, when the passage permission signal is artificially input after the personal information is displayed, the number of passages is added. There is an effect that can improve the traffic qualification of.

Further, in the sixth aspect of the invention, since the fingerprint reader is incorporated in a portion which a passerby normally contacts or operates, a fingerprint can be input without requiring the passerby to perform a special operation. This makes it possible to prevent a passerby from feeling useless.
