Abstract

PROBLEM TO BE SOLVED: To completely prevent another person from passing through a gate with a registered person by simply detecting the camouflage of carrying another on one's back, in one's arms, on one's shoulders or tightly fitting two bodies to pretend one body so as to improve detecting precision whether only one person enters a gate zone. SOLUTION: A gate passage desiring person enters a gate zone between first and second gates 11 and 12 and inputs a retina pattern from an individual information input device 2 to receive collation between with registered patterns PatA, PatB.... The weight of the entering person is measured by a weight sensor 3 on a floor surface. When the pertinent registered patterns PatA, PatB exist, a registered weight corresponding to it (e.g. WtA=65kg at the time of PasA.) and the weight measured by the sensor 3 are evaluated and when it is within such an allowable value as is added with about the weight of the baggage, a final gate can be opened from the gate zone. At the time of being over the allowable value, it is possible that another person enters together and opening is not permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to security that can be applied to entrance and exit management of various facilities such as a laboratory, a computer room, a vault, an office, a store, a factory, a warehouse, an intelligent office building, a ladies 'apartment, and a members' club. Related to gate system.

[0002]

2. Description of the Related Art In recent years, in response to demands for maintaining high security, a gate zone for partitioning between two doors has been provided at the entrance of a facility, and a personal information input device comprising a retinal reader has been installed inside the gate zone. Under the condition that the number of entrants in the zone is limited to one by a sensor or a heart rate sensor, the entrants are distinguished by checking the retinal pattern to determine whether they are registered in advance or not. A system has been proposed that strictly excludes the entry of a room and the accompanying room with a registrant (Japanese Utility Model Laid-Open No. 8-819).

[0003]

In the above system,
With no keys or cards, you will be free from the risk of loss, theft, and forgery, and you can expect extremely high security. In fact, as compared with a so-called auto-lock system for an apartment or the like, no card is required, convenience and security are much higher, and entry to a rush-on flight can be almost eradicated. However, footprints and heartbeats are used to detect whether there is only one person in the zone.Footprint detection has a risk of not being able to detect impersonation due to piggybacks, hugs, shoulders, body contact, etc. There is a problem that the system is complicated and excessively complicated.

[0004] The main object of the present invention is to make it possible to effectively detect a single person impersonation due to a piggyback, a hug, a shoulder carriage, a close contact with the body, etc. without excessively complicating the system, and that only one person enters the gate zone. It is an object of the present invention to provide a security gate system that can increase the detection accuracy of the information, ensure that only the registrant alone passes through the gate, and ensure higher security.

[0005]

According to the first aspect of the present invention,
To achieve the above main purpose, as shown in FIG. 1 or 4,
A gate zone 1 partitioned between the first and second gates 11 and 12, a personal information input device 2 installed in the gate zone 1,
A weight sensor 3 that measures the weight of an intruding object that has entered the gate zone 1, and compares input personal information input from the personal information input device 2 with registered personal information under closed conditions of both gates 11 and 12. Weighting means 5 for evaluating whether or not the measured weight of the weight sensor 3 is within an allowable value based on the registered weight information corresponding to the registered personal information that matches and matches the matching personal information. And a gate opening permitting means 6 for permitting the opening operation of the passing front gate from the gate zone 1 on condition that the allowable value of the weight is provided.

Each of the gates 11 and 12 includes a door that rotates about a vertical axis, a door that slides horizontally or vertically, a so-called shutter and a circuit breaker, and the like.
The concept includes both automatic opening and closing. Also, the gate on the front side of the passage that is finally opened is the first gate 1
When entering the room from 1 through the second gate 12, the gate is the second gate 12, and when leaving the room, the gate is the first gate 11.
The personal information input device 2 includes a retinal reader that reads a blood vessel pattern of the retina, which is the innermost layer of the eyeball wall, using weak infrared light, an iris reader that reads an iris pattern between the cornea and the lens of the eyeball, and a fingerprint reader. , Voiceprint reader, signature handwriting reader, and the like.

The allowable weight value is determined in a range of plus or minus (possibly plus only in some cases) several kg to several tens kg. Since the system coverage is likely to not include small children in the gate passers, approximately 20kg
The range may be up to 30 kg, for example, 30 kg. This is based on the fact that few adults weigh less than 30 kg and that baggage rarely exceeds 30 kg. That is, assuming that the registered weight information serving as a reference for a certain person is 65 kg, even if this person measures 90 kg by the weight sensor 3, that person happens to bring in 25 kg of extremely heavy baggage. Instead of being there, it seems that one-person access is being followed. And if the measured weight of the person is 100 kg, there is a possibility that there is a very thin accompanying person of 35 kg, and it is considered that a plurality of persons enter. In addition, if the weight is set at about 30 kg, the evaluation error caused by a sudden decrease or increase in weight in a short period does not cause a problem, and high evaluation accuracy is maintained only by updating the registered weight information about once every six months, one year, or several years. Also becomes possible.

However, if the carry-on of baggage is restricted by operation, a small allowable value of, for example, 5 to 10 kg, which can take into account a change in clothes at the most, can be added to the standard weight increase and decrease. By doing so, it is possible to thoroughly distinguish one person, including a child except an infant.

The invention according to claim 2 eliminates the problem that accurate weight measurement cannot be performed when an entrant in the gate zone 1 leans against a wall or touches a part of a body, and a companion is a ninja. Or sticking to the wall like a limb or hanging on the wall using suction equipment,
As shown in FIG. 1 or 4, in order to eliminate the adverse effect of evading the weight evaluation, as shown in FIG. 1 or 4, a distortion sensor 7 for detecting the distortion of the wall surrounding the gate zone 1, and when the sensor 7 detects the distortion, the passing front side gate is moved. Wall lean eliminating means 7 that cannot be opened
0 was provided. The wall surfaces surrounding the gate zone 1 include not only the partition walls 13 and 14 but also the gates 11 and 12 themselves and the ceiling. The distortion of the wall surface includes both positive distortion due to pressing force and negative distortion due to suction force.

[0010] The invention according to claim 3 is mainly for raising a caution and prompting a formal process when a companion is leaning or touching a wall without knowing it even though there is no companion. As shown in FIG. 1 or 4, a wall leaning alerting means 71 for outputting alerting information is provided in the gate zone 1 when the wall leaning elimination means 70 operates, in order to ensure smooth operation. . This alerting means 71
Includes various types of devices such as a device that outputs a voice message from a speaker, a device that warns with a chime or a buzzer, and a device that displays characters or lighting signs on a display or lamp arranged in the gate zone 1. .

According to a fourth aspect of the present invention, as shown in FIG. 4, when the weight sensor 3 is smaller than the gate zone 1 or when the gate zone 1 is too wide, the weight sensor 3. When there is a measurable area A and an unmeasurable area B, an unscheduled intruding object sensor 8 that senses an unscheduled intruding object in the unmeasurable area B to ensure accurate weight measurement and cut off accompanying persons. , This sensor 8
When an unscheduled intruder is detected in step (1), an unscheduled intruder removing means 80 that does not open the gate on the front side of the passage is provided. The unscheduled intruder sensor 8 is a CCD solid-state image sensor or an infrared thermal image sensor installed on the ceiling or the like of the gate zone 1, or a pressure sensor or a strain sensor laid or embedded in the unmeasurable area B on the floor surface. It consists of.

[0012] The invention described in claim 5 is mainly used in a case where a companion is straddling the unmeasurable area B without knowing that there is no companion, or a case where the companion is inadvertently accompanied by no malicious intent. As shown in FIG. 4, when the unscheduled intruding object elimination means 80 is activated, the alert information is displayed in the gate zone 1 so as to call attention and urge normal processing to ensure smooth operation. Is output. This alerting means 81 is also similar to the above,
Various types of devices, such as a device that outputs a voice message from a speaker, a device that issues an alarm with a chime or a buzzer, and a device that displays characters or lighting signs on a display or a lamp disposed in the gate zone 1 are included.

[0013] The invention according to claim 6 suppresses the original abnormality accompanied by a companion, and at the same time, even if there is no companion, an abnormal weight measurement occurs due to an improper position of the entrant or vibration or impact. In order to draw attention to the case and ensure smooth and proper operation, as shown in FIG. 1 or 4, when the measured weight deviates from the permissible value in the evaluation by the weight evaluation means 5, attention should be paid in the gate zone 1. An alerting means 51 at the time of deviating from an allowable value for outputting alerting information is provided. As described above, the alerting means 51 also sends a voice message from a speaker, issues a warning with a chime or a buzzer, or displays characters or lighting signs on a display or lamp arranged in the gate zone 1. Etc. are included.

According to a seventh aspect of the present invention, the permission to open the front gate on the passing side is canceled in a fixed time, and a prompt action is required to maintain the security strictly. Also in this case, as shown in FIG. 1 or 4, in order to eliminate the trouble of having to go out of the gate zone 1 and start over from the beginning, as shown in FIG. The gate cannot be opened, and if the gate zone 1 is not empty at this time, a back-up back-up means 9 is provided to enable re-verification of personal information under the closed condition of both gates 11 and 12. Whether the gate zone 1 is empty or not can be easily determined based on whether or not the output of each of the sensors 3, 7, 8 is 0 (none).

[0015]

According to the first aspect of the present invention, as shown in FIG. 1 or 4, a person who wants to pass through the gate enters the gate zone 1 defined between the first and second gates 11 and 12.
The personal information is input from the personal information input device 2, and the registered personal information PatA, PatB,.
・ Check with. The weight of the entrant is measured by the weight sensor 3. There is applicable registered personal information,
When the collation matches, the registered weight information (WtA) corresponding to the collated registered personal information (for example, PatA) is obtained.
= 65 kg) is an evaluation standard for the weight measured by the weight sensor 3. Then, the reference value and the measured weight of the weight sensor 3 are evaluated by the weight evaluation means 5, and if the difference between the two is small and within the allowable value, the gate opening permitting means 6 causes the passing front side gate from the gate zone 1 to pass. Can be opened. Conversely, when the difference between the two is large and deviates from the allowable value, there is a possibility that a companion is present, and the gate on the front side of the passage cannot be opened.

In this way, by combining the reliable and simple distinction means of collating personal information and evaluating weight,
Without overcomplicating the system, only one registered person can pass through the gate, effectively seeing piggybacks, hugs, shoulders, body contact, etc., and strictly cut off accompanying persons for high security. Can be secured.

According to the second aspect of the present invention, as shown in FIG. 1 or 4, if the resident of the gate zone 1 leans against the wall, accurate weight measurement cannot be performed. This is sensed, and the wall lean eliminating means 70
As a result, the front gate on the passing side does not open. For this reason, evaluation errors due to inaccurate weight measurement can be eliminated, and high security can be ensured. Also, even if a companion tries to escape the weight evaluation by sticking his limbs to the wall like a ninja, or hanging on the wall using suction devices or the like, the sensing by the strain sensor 7 and the wall lean elimination means 70 are also possible. As a result, the front gate on the passing side is not opened, and higher security can be ensured.

According to the third aspect of the invention, when there is a wall leaning without a companion, a wall leaning with a companion, or the above-mentioned ninja act, the wall leaning alerting means 71 alerts the inside of the gate zone 1. Is done. It is possible to encourage legitimate behavior to a legitimate single independent entrant without a companion, and ensure smooth operation. In the case of a fraud with a companion, the fraudulent act is restrained.

According to the fourth aspect of the present invention, as shown in FIG. 4, when a resident of the gate zone 1 crosses over the area B where the weight sensor 3 cannot measure, accurate weight measurement cannot be performed. This is sensed by the unscheduled intruding object sensor 8, and the unscheduled intruding object elimination means 80 does not open the passing front side gate. For this reason, evaluation errors due to inaccurate weight measurement can be eliminated, and high security can be ensured. Also, when the accompanying person is in the measurement impossible area B,
Due to the detection by the unintended intruder sensor 8 and the elimination means 80, the passing front gate is not opened, and complements the case where the measurable area A of the weight sensor 3 with respect to the gate zone 1 is relatively small to provide high security. Can be kept.

According to the fifth aspect of the present invention, as shown in FIG. 4, when there is an intruder in the unmeasurable area B, the unexpected intruder alerting means 81 alerts the inside of the gate zone 1. You. It is possible to encourage legitimate behavior to a legitimate single independent entrant without a companion, and ensure smooth operation. In the case of a fraud with a companion, the fraudulent act is restrained.

According to the sixth aspect of the present invention, as shown in FIG. 1 or 4, there is no accompanying person, but when the weight evaluation is abnormal due to the improper position of the entrant or the influence of vibration or impact, When the weight evaluation is abnormal due to the presence of a companion, a warning is issued in the gate zone 1 by the permissible value deviation warning device 51. It is possible to encourage legitimate behavior to a legitimate single independent entrant without a companion, and ensure smooth operation. In the case of a fraud with a companion, the fraudulent act is restrained.

According to the seventh aspect of the present invention, as shown in FIG. 1 or 4, even if the gate opening permission is issued by the gate opening permitting means 6, the gate opening permission is terminated after a certain period of time, and prompt action is required. While maintaining high security, if the vehicle stops in the gate zone 1 and does not actually pass through the gate, it is not necessary to go out of the gate zone 1 and start over from the beginning, and the back-up means 9 has a slackness.
Thus, it is possible to pass through the gate after re-checking by re-entering personal information while staying in the gate zone 1.

Further, when the measured weight deviates from the allowable value in the evaluation by the weight evaluating means 5, a warning message indicating, for example, "Please stand at the correct position" is output in the gate zone 1 as well. 51 are provided. Furthermore, the second gate 12 cannot be opened after a lapse of a fixed time period of about several seconds to several minutes from the issuance of the gate opening permission by the gate opening permission means 6, and at this time, there is an output from any of the sensors 3 and 7, If the zone 1 is not empty, a back-up backup means 9 is provided to enable the personal information to be re-verified under the closed condition of the gates 11 and 12.

A series of entry management is performed according to the procedure shown in FIG. First, the person who intends to enter the room enters a correct password using the numeric keypad 10 (steps a and b), unlocks the first gate (c), opens it (d), and opens the gate zone 1
(E), and the first gate 11 is closed (f). By pressing the unlock button 15 (g) from the inside of the gate zone 1, the first gate 11 can be opened (h) to go out.

In the gate zone 1, the retinal pattern is read from the personal information input device 2 (i), and is compared with the registered patterns PatA, PatB... (J). If there is no corresponding registered pattern and matching cannot be obtained, it is possible to go outside without entering the room via the pressing of the unlock button 15 in step g.

When the collation matches, the identification number confirmed by the collation (for example, the identification number IDA of Mr. A who collated with PatA), the measured weight Wt of the weight sensor 3,
The output of the strain sensor 7 is transferred to the calculation unit for the subsequent processing (k).

When the distortion is sensed (m), a message "Please do not lean on the door or wall" is output from the wall holding alerting means 71 (p), the process returns to step g, and re-verification (i or less) is performed. Or go out (h) not to enter the room.

If there is no distortion sensing, the identified identification number I
It is evaluated whether the difference between the registered weight information (WtA = 65 kg) corresponding to the DA and the measured weight Wt is within a predetermined allowable value (30 kg) (s). If the measured weight Wt is 100 kg, the difference from the reference value 65 kg is 35 kg and the allowable value is 30 kg.
In order to deviate from the allowable value, a message "Please stand at the correct position" is output from the permissible value departure warning means 51 (t), and the process returns to the step g. You can choose.

If the measured weight Wt is more than 35 kg and less than 95 kg, it is determined that Mr. A is alone and the second gate 12 is permitted to be opened (u). The entrant A can enter the room by pressing the unlock button 16. When a predetermined time of, for example, about 20 seconds elapses from the issuance of the opening permission of the second gate 12 (v), the opening permission once issued is canceled,
The second gate 12 is locked (w). During this time, if the vehicle stays in the gate zone 1 and stops, the sensor 3
7 (x), the process returns to step g, and a backup can be made by selecting re-matching (i or less) (backup backup means 9).

FIG. 4 shows a second embodiment in which the weight sensor 3 is smaller than the gate zone 1,
This is an application example in a case where there is a measurable area A and a non-measurable area B by the weight sensor 3 in the gate zone 1 due to circumstances such as a case where is too wide. In this example, an unscheduled intruder sensor 8 composed of a CCD type solid-state image sensor mounted on a ceiling for sensing an unscheduled intruder in the unmeasurable area B,
When an unscheduled intruder is detected in the above, the unscheduled intruder removing means 80 which does not open the second gate 12 is activated.
There is provided an unscheduled intruder alerting means 81 for outputting an alerting message from the alerting output body 200 such as a speaker, "An object other than the person has been detected. Please leave anyone other than the person."

In this case, as shown in FIG. 5, after judging the presence or absence of distortion detection (step m), the presence or absence of an unscheduled intruder by the unscheduled intruder sensor 8 is determined (q). If yes, the above-mentioned message is output from the unscheduled intruding object alerting means 81 (r), and the process returns to step g, so that re-verification (i or less) or going out (h) not entering the room can be selected. The other points are the same as those in FIG. 3 except that the sensor output includes the unscheduled intruder sensor 8 in steps k and x.

In the above, the first gate 11 to the second gate 11
The entrance management toward the gate 12 has been described.
