Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention requires security functions such as a room for storing or manufacturing money or the like, a computer room, a data storage room, an information management room, an equipment management room, and a research laboratory. In particular, the present invention relates to a security system having a function of managing the number of occupants in a building and a security system for preventing forgetting to set a security system.

[0002]

2. Description of the Related Art Various security systems have been introduced for buildings requiring a security function, and confidential information, important articles and the like are managed. For example, ID
Verification is performed using numbers or ID cards, and access to the building is controlled and regulated. Such a conventional security system does not necessarily have a high security function. For example, the ID number, card theft, etc.
In some cases, unauthorized persons may enter the building by lending.

In response to such a problem, especially when entering and leaving a confidential area (building), biological personal information such as a fingerprint is registered in advance, and only the registered person (authorized person) enters. There are things that allow you to leave.

[0004]

However, even in the above-described management system, unauthorized use of IDs and entry of a non-permitted person into a confidential area (building) of a non-permitted person are prohibited. Intrusion may occur. One of the causes is that management is not performed on the authorized person, such as which authorized person entered and exited the room. Also,
If there is only one authorized person in the confidential area,
It is also conceivable that an unauthorized act such as theft by the authorized person occurs.

On the other hand, even if a security system such as a security system is introduced to prevent unauthorized access by unauthorized persons at night or the like, the last person who leaves the confidential area forgets to operate the security system. Would result in a situation where no security system exists,
As a result, there is a possibility that illegal intrusion may occur.

SUMMARY OF THE INVENTION An object of the present invention is to manage the number of occupants in a building and to prevent or suppress one occupant in the building from staying in the building in order to thoroughly control the entrance and exit of the permitted person. An object of the present invention is to provide a security system and a system for preventing a user from forgetting to set a security system or the like.

[0007]

In order to solve the above-mentioned problems, a security system having a function of managing the number of occupants in a building according to the present invention (Claim 1) comprises: Entry / exit monitoring means provided at a common or individual entrance / exit of a specific security area (hereinafter collectively referred to simply as a security area) and checking at least the number of entrances and exits in the security area;
The number of occupants in the security area is calculated by taking the difference between the number of occupants and the number of occupants by the entry / exit monitoring means, and the number of occupants is calculated by the number of occupants. And a one-person processing means for performing a one-person processing when the number of occupants becomes one.

In such a security system, when the number of occupants in the security area becomes one, the one-person processing means is performed. Therefore, the presence of one person in the security area is prevented or suppressed. It is possible to prevent theft by an insider. As the one-person processing means, for example, an occupancy history storage means is provided to store the fact that one person is occupied together with time information,
It is possible to adopt a method of notifying a management room or the like provided in an area different from the security area when one person has been in the room for a predetermined time or more. In addition, when the single occupant tries to leave the security area last time, a means for restricting the exit according to various conditions may be adopted as the one-person processing means. For example, there is an exit regulation system that regulates exit by forgetting to switch off electrical appliances, gases, and the like, and forgetting to set a security system, and allows exit to be permitted only after they are completed.

Further, the security system having a function of managing the number of occupants in a building according to the present invention (claim 2) is provided as one-person correspondence processing means according to the above-mentioned first aspect, wherein the single-person occupant is provided with the function. It is provided with warning output means for outputting warning information for notifying the fact and / or outputting warning information for urging a person in the room to leave the security area.

In this case, the warning output means can warn one occupant of the fact that the occupant is occupied, so that the occupancy of one person in the security area can be minimized. Become. As a result, security for the authorized person is enhanced, and an environment in which an insider's insider is less likely to perform an illegal action can be created.

According to the first and second aspects of the present invention, the entry / exit monitoring means includes an identity verification device for performing identity verification of the entered / exited person using a fingerprint, a retina, a key, a card, or the like, and an information indicating that the identity verification is qualified. Unlocking means for selectively unlocking the door based on a signal, wherein only a pre-registered entry permitting person is permitted to enter and exit the security area. The number of entering and exiting rooms may be checked based on the number.

In this case, only persons who have been registered in advance are allowed to enter and leave the security area by the door-type entry / exit permitting device, and the person who enters and exits is identified by the identity verification device. I understand. Therefore, it is possible to identify who is the occupant who has become one person, and it is possible to manage entry / exit for the person who is permitted to enter the room and manage the occupancy status in detail.

[0013] Further, the entry / exit monitoring means is provided with two sheets arranged at a predetermined space on the assumption that only one person can exist in order to prevent two or more persons from passing at the same time. A door and one or more combinations of personal identification devices such as fingerprints, retinas, keys, cards, and weight sensors that are provided between the two doors and enter the space within the two doors And an unlocking means for selectively unlocking the two doors based on a signal indicating that the identity verification is qualified, and an identity verification system for performing identity verification of one person in the space of the two doors. And checking the number of persons entering and exiting the room based on room entrance / exit information from a room entrance / exit permitting apparatus with two doors that sequentially passes the two doors one by one after personal identification.

As described above, when the entry / exit is monitored based on the entry / exit information from the two-door type entry / exit permission device, the entry / exit of only one person who has been permitted to enter / exit by the two-door type entry / exit permission device. Permission can be granted, and it is virtually impossible to enter a room with a non-permitted person. Therefore, the number of occupants can be surely managed, and the occupants who have become one can be specified, and thorough management can be performed on the persons permitted to enter the room.

On the other hand, in order to solve the above problems, the security system for forgetting to set a security system according to the present invention comprises a security area in a building or a specific security area in the building (hereinafter, these are collectively simply referred to as security area). Crime prevention or disaster prevention on holidays and other absences (hereinafter simply referred to as crime prevention)
Security system for the last exited person is set in the security system, provided at the entrance of the security area, and at least entry / exit monitoring means for checking at least the number of entrances and exits in the security area. The number of occupants in the security area by counting the difference between the number of occupants and the number of occupants by the entry / exit monitoring means; When the number of occupants becomes one, the occupant only detects that the security set signal generated by setting the security system is on, and then the last occupant leaves the room. And a leaving permission device that is in a possible state.

With the introduction of the security system for forgetting to set the security system, the last person who remains in the security area cannot leave the room unless the security system is set (operated). Forgetting to set is prevented. Therefore, it is possible to prevent intrusion, theft, and the like due to forgetting to set the security system.

In the security system for preventing forgetting to set the crime prevention system, the exit permission device is provided with a door-type entrance / exit permission device or a two-way exit permission device, similarly to the security system having the function of managing the number of occupants in the building. A single door type entrance / exit permission device can be provided. Also in this case, the reliability of the management of the number of occupants is increased, and the system for preventing forgetting to set the security system can be correctly operated.

[0018]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a security system having a function of managing the number of occupants in a building according to the present invention;
It is the schematic which shows the installation example of each apparatus which comprises a security system and forgetting to set a security system. At the entrance of the security area 100 shown in the figure, a two-door type entrance / exit permission device 1 is provided, and the two-door type entrance / exit permission device 1 prevents two or more persons from passing at the same time. for,
A predetermined space is provided between two doors on the assumption that only one person can exist.

Also, in the vicinity of the two-door type entry / exit permission device 1, when the number of occupants in the security area 100 becomes one, a warning for informing the occupants of the fact is provided. Information and / or security area 1
A warning output device 2 for outputting warning information for urging the user to leave the room from 00 is provided, and a crime prevention system 3 for crime prevention or disaster prevention at night, on holidays, or in the absence of another person is provided.

The warning output device 2 automatically outputs a voice or a dial tone from a speaker, or outputs a voice of a manager or the like who is present in a management room or the like provided in an area different from the security area 100. It is possible to adopt a method of flowing through a speaker. In addition, the security system 3 employs a detection sensor such as an infrared sensor for detecting an unauthorized intruder or the like as a security device, and is provided with alarm means for receiving a detection signal from the sensor and generating an alarm sound or the like.

FIG. 2 is a block diagram showing the configuration of a security system having a function of managing the number of occupants in the building of FIG. 1 and a security system for preventing forgetting to set a security system.
The control unit 10 controls the two-door entry / exit permission device 1, the warning output device 2, and the security system 3. The control unit 10 performs the result of the personal verification by the personal verification device (the personal identification device 5 and the weight sensor 11) provided in the space between the two doors (inside the two-door box) of the two-door access permission device 1. In response to this, there is provided an application program (AP) for issuing an instruction to open and close the electric locks 15 and 17 to the two-door type entrance / exit apparatus 1 and an operation program (OS) for operating the application. ing.

On the other hand, in the two-door type entrance / exit permitting apparatus 1, a ten-key unit (also simply referred to as a ten-key) 14 is provided at the lower gate (generally the entrance side) of the two-door when entering the area 100. An electric lock 15 is provided, and a numeric keypad 16 and an electric lock 17 are provided at a gate on an upper side (generally, an exit side).

An instruction for opening and closing the electric locks 15 and 17 from the control unit 10 is transmitted to a two-door control board 13 provided inside the two-door type entrance / exit permitting device 1, and is transmitted to the two-door control board. A driver 13 drives the electric locks 15, 17 and the display devices 29, 31, 32, 34 (described later) shown in FIG. Note that when entering and exiting the security area, entry into the two doors is performed by key input of an ID number on the ten keys 14 and 16.

The control unit 10 stores the entry / exit history of the individual identified by the personal identification device of the two-door type entry / exit permission device 1 to check the number of entry / exit in the security area 100. Exit monitoring means, number of occupants calculating means for calculating the number of persons occupying the security area 100 by taking the difference between the number of occupants and the number of exits, and storing the temporal change of the number of occupants. Data storage means.

More specifically, the control unit 10 includes an I / O port 10a, a CPU 10b, a ROM 10c, a RAM 10d
And the above-described operation system (OS) and application program (AP) are written in the ROM 10c. The RAM 10d is assigned an entry / exit history memory 10f for storing individual entry / exit history, and an occupant number counter (memory) 10e for storing the occupant number. The occupant number counter 10e may be, for example, an up-down counter, and is incremented for each entry history and decremented for each exit history to store the latest number of occupants. . CPU 10b
Reads out this count value, for example, at each exit process, and when the exit value is permitted, the count value is “1” (when the number of occupants becomes 1) or “0” (the last When one person leaves the room), a later-described warning or room exit restriction is performed in accordance with the aforementioned AP (program). In this example,
Mainly, the counter 10e serves as the number of occupants calculation means and the number of occupants data storage means.
Function as an entry / exit monitoring unit, and the AP (program) and the CPU 10b executing the AP constitute a one-person correspondence unit and an exit permission device.

It is to be noted that, instead of the above-mentioned up-down type occupant number counter (memory), an occupant number counter (memory) for storing the total number of occupants per day, for example, It is also possible to provide a number-of-leaves counter (memory) for storing the total number of persons (total number), and the CPU reads out both to calculate the difference and confirm the current number of occupants.

When the number of occupants calculated by the occupant number calculating means of the control unit 10 becomes one, the control unit 1
0 indicates that a warning information output command is issued to the warning output device 2. Also, when the number of occupants becomes one, the control unit 10 sets the security system 3 (to activate the same) when the number of occupants becomes one. A security system that allows the user to leave the device 1 is provided with a system for preventing forgetting to set. The security system 3 is set by operating the operation switch 3a, and the security device 3b such as an infrared sensor is activated. Further, it is also possible to adopt a central batch system in which the control unit 10 is provided in a management room or the like on another floor.

On the other hand, a central control unit 9 is connected to the control unit 10, and the central control unit 9 performs overall control together with other security systems (not shown) (for example, provided in security areas on different floors). I have. The central control unit 9 inputs and stores information such as the expiration date of personal information such as a fingerprint, a retina, a key, a card, and weight related to the personal identification device, or the use history of each device. Manages all information related to the use of the system. Specifically, the personal information is registered in the central control unit 9 and distributed to the control unit 10 or each personal verification device. The personal information may be registered and stored in each personal verification device.

Next, the passage of the two-door type entrance / exit permission device 1 will be described with reference to FIG. Security area 1
At the time of entering the room at 00, the passer-by A enters the key of the ID number using the numeric keypad 14 provided near the gate entrance of the two doors, and the gate is unlocked by the collation,
Entry into the two-door box is permitted. Passenger A checks the biometric characteristics by the personal identification device 5 in the two-door box and the weight by the weight sensor 11, and if the verification is qualified, the gate is unlocked and the security area is released. Entry to 100 is allowed.

On the other hand, when the user leaves the security area 100 (in FIG. 3, the traffic passes in the opposite direction),
Numeric keypad 16 provided near the gate entrance of two doors
Thus, the user inputs the ID number by key, and thereafter, the same operation as when entering the room is performed, and the exit is permitted.

As the personal identification device 5, a fingerprint identification unit 20 as shown in FIG. 4 can be employed.
The fingerprint identification unit 20 includes a numeric keypad 23 and the fingerprint identification device 2.
The passer-by A enters the ID number into the numeric keypad 23 and touches the fingerprint recognition unit 21 of the fingerprint identification device 22 with a finger to input the fingerprint. The numeric keypad 23 is provided because the fingerprint information of the individual is stored in association with the ID number of the individual. When the ID number is input by the numeric keypad 23, the fingerprint information corresponding to the ID number is compared. The fingerprint information is recognized as one (registered fingerprint information), and the actually input fingerprint information is used as the other, and the two are compared (match determination). A retinal discriminator 1 as shown in FIG.
2 can also be used.
An ID number is key-input to 2b, and the retina detecting unit 12a detects (inputs) its own retina. Numeric keypad 12 in this case
b is also because the individual's retinal information is stored in association with the individual's ID number, and when the ID number is input using the numeric keypad 12b, the retinal information corresponding to that ID number is compared with one of the comparisons (registered and registered). (Retina information), and the actually input retinal information is used as the other, and the two are compared (match determination). The above fingerprint identification unit 2
The retinal identifier 0 and the retinal discriminator 12 compare input information with fingerprint and retinal data registered in advance for each device.

Although a method of collating a fingerprint and a retina is a known technique, its content will be briefly described. There are various methods for fingerprint identification, for example, a feature point extraction method can be adopted. In the feature point extraction method, first, feature points such as an end point and a branch point of a fingerprint, which are generally said to be about 200 for a human, are extracted from a fingerprint image, and the image data is stored. The method of extracting feature points is performed by capturing a scanned image with a sequence of digital lines and thinning the pixels of such a sequence. That is, the number of links in the point sequence is calculated. For example, if the number of links is 0, it can be eliminated as an isolated point (noise). If the number of links is 1, it is extracted as an end point of a feature point. The surrounding pixels are extracted as the branch points of the feature points. If the number of connections is 2, it is a connection line (not a feature point) and is not extracted as a feature point. If the number of connections is 4 or more, it is an intersection and is not extracted as a feature point. In this manner, image data is stored for each feature point. On the other hand, similar feature point extraction is performed on the input image, and a plurality of (e.g., eight) feature points are extracted therefrom. It is determined whether or not it matches the feature point of the stored image data. In the determination method, at a certain feature point (for example, a branch point), stored registered image data and input image data of an input branch point are compared by a specific algorithm, and a threshold value (for example, the total number of pixels) is determined. If the number of matching pixels is equal to or greater than (80% of the above), it is determined that the feature points match. Then, of a plurality of (eg, eight) feature points extracted from the input image, a fixed value (eg, three)
When it is determined that the feature points match, the fingerprint matching is determined. In the feature point extraction method, it is said that, for example, if about 12 or more out of about 200 feature points match, a matching match may be made.

Regarding the retina matching method, first,
For example, light is generated by a pulse-weighted (for example, DC 5 V) incandescent tungsten lamp, and a spiral near-infrared ray that rotates around a pupil of the eye at a predetermined lead angle (for example, 10.3 degrees) into a column shape. create. This weak light passes through the iris and is reflected and absorbed by the retinal vascular pattern, which differs for each individual. The reflected light returning to the same light emission path hits the beam splitter, travels to the detector, is analyzed by the detector, and becomes an analog signal that is the basis of retinal pattern data. The signal detector sends the analog signal to an A / D converter where the signal is digitized, processed into, for example, 96 bytes of pixel data and stored in a file. At the time of registration, for example, five measurements are performed to ensure more reliable reproducibility, and the average value is registered data. When the reading operation after registration is performed in the same manner, the A / D converter sends a digital signal to the comparator, and a specially programmed search algorithm is used.
It is checked whether registered data stored in the nonvolatile memory matches input data at the time of identification. Actually, if the input data input and the stored registration data have the number of matching pixels equal to or more than a threshold value (for example, 80% of the total number of pixels), it is determined that the retinal collation matches. I do.
In such a retinal discriminator, the data is stored in a small memory of, for example, 96 bytes, so that the misrecognition rate at the time of personal discrimination is extremely low, and has a high accuracy of about once per million or less. As described above, the personal identification using the retina has a low instability factor, and the biological characteristics are held in the eyes and cannot be seen from the outside. Therefore, problems such as forgery, loss, and theft are solved.

The collation / passing procedure in the two-door type entrance / exit permission apparatus 1 will be described with reference to FIG. At the gate, when an ID number is input to the numeric keypad 14 by key input, collation with data registered in the numeric keypad 14 is performed. If the collation is appropriate, the electric lock 15 is unlocked and the gate can pass. Whether or not the matching is possible is indicated by the gate entry display lamp 29 (for example, of the two lamps,
One lighting indicates verification OK, and the other lighting indicates non-verification).

With the above operation, entry into the two-door box is permitted, and after entry, the personal identification device 5 is operated by locking (automatically) the electric lock 15 at the gate. At this time, if the gate is not locked, the personal identification device 5 is not operated. When a biometric feature is input to the personal identification device 5, the personal identification device 5 compares the input information with identification data registered in advance, and the result of the comparison is transmitted to the control unit 10. In addition, this collation result
It is also possible to transmit to the control unit 10 via the two-door control board 13.

When the collation result of the personal identification device 5 is negative, the control unit 10 sends the "error lamp display", "error announcement execution", and "gate unlock" commands to the two-door control board 13. . The two-door control board 13 unlocks the electric lock 15 of the gate, displays an error message on the gate entry display lamp 32, and announces the error in the box via the audio board 28. , To encourage you to leave the box. Note that it is also possible to make an announcement prompting the execution of re-matching up to a specific number of times (for example, three times), and to still leave the box if the matching result is negative.

On the other hand, if the collation result of the personal identification device 5 is acceptable, the control section 10 identifies the individual of the passer-by A from the registered data, and registers the individual's registered weight (control within a predetermined range). And the weight sensor 11).
Is further collated with the weight information from, and it is strictly identified that there is only one passer-by. If the above verification is qualified (possible), the control unit 10 sends a command to unlock the gate electric lock 17 to the two-door control board 13 and the two-door control board 13 17 will be unlocked. Through the above process, the passer-by A is permitted to enter the security area 100.
The verification of the body weight of the individual and the verification of biological characteristics such as the retina may be performed by the former and then the latter, or both may be processed simultaneously.

The passing process of the two-door type entrance / exit apparatus 1 when entering / leaving the room will be described below with reference to FIGS. 7 and 8 while referring to FIG. In this passing process, the number of occupants management function and the system for preventing forgetting to set the security system are operated.

First, upon entering the room, in S1 of FIG. 7, when an ID number is entered by a key on the numeric keypad 14 of the gate, collation with registered data is performed (S2). If the collation is appropriate, the process proceeds to S4, where the electric lock 15 of the gate is unlocked, and it becomes possible to enter the two-door box (S4).
Five). If the verification is ineligible, an error message is issued in S3 and the electric lock 15 remains unlocked, so that entry to the security area 100 is disabled.

After entering the two-door box, the electric lock 15 of the gate is locked (automatically) in S6. The locking causes the personal identification device 5 to operate, and in S7, a biometric feature such as a fingerprint or a retina is input to the personal identification device 5 and it is confirmed whether or not it matches the data registered in advance (S7).
8). If the collation result of the personal identification device 5 is negative, an error message is issued in S15, the gate remains unlocked, the gate is unlocked, and the exit from the two-door box is prompted, and the security area 100 is entered. Becomes impossible (S16).

On the other hand, if the collation result is acceptable, the individual who wishes to pass is identified in S9 and the weight sensor 1
The weight measurement according to 1 is performed (S10). In S11, the measured weight is compared with the registered weight range of the individual identified in S9. If verification is not possible (such as when two people enter the room with two doors together), an error message is issued in S15, the gate remains unlocked, the gate is unlocked, and exit from the two door box is performed. Be prompted.
If the collation is possible, the process proceeds to S12, where the entry history is stored together with the personal information in the entry / exit monitoring means (entry / exit history memory 10f) of the control unit 10. Thereafter, the electric lock 17 of the gate is unlocked in S13, and the security area is set. The entry to the room 100 is permitted (S14).

Next, regarding the passing process at the time of leaving the room, first, in S50 of FIG.
When the D number is input by a key, the number of occupants is calculated by the occupant number calculating means (occupant number counter 10e) of the control unit 10, and whether or not the passing applicant is the last occupant (last occupant) is determined. Is confirmed (S51).

If it is determined that the person has finally left the room, the process proceeds to S52, where a check is made in the control section 10 as to whether the security system 3 has been set.
And the electric lock 17 at the gate remains unlocked. The error message in this case is
A message prompting the user to set the security system 3 is output. After the security system 3 is set, the process from S50 is performed again. If the security system 3 is set, the process proceeds to S54, where it is checked whether the input ID number matches the registered ID number.

On the other hand, if it is determined in step S51 that the user is not the last exit, the process proceeds to step S54, where the ID is compared with the registered ID number. If the verification is qualified, the process proceeds to S55, where the electric lock 17 of the gate is unlocked, and it becomes possible to enter the two-door box (S56). If the verification is ineligible, an error message is issued in S53 and the electric lock 17
Remains unlocked, and it is not possible to leave the security area 100. The error message in this case is
This is a message for notifying the ID number collation mismatch, and the process from inputting the ID number in S50 is performed again. This ID number input is performed a plurality of times (for example, three times).
If the registration does not match the registered ID number, a warning device or the like may be activated.

After entering the two-door box, the electric lock 17 of the gate is locked (automatically) in S57. The locking causes the personal identification device 5 to operate, and in S58, the personal identification device 5 checks biometric features such as fingerprints and retinas, and identifies an individual from pre-registered data (S58).
59). Further, the weight is measured by the weight sensor 11 in S60, and the measured weight is collated with the registered weight range of the individual identified in S59 (S61). If collation is impossible (such as simultaneous exit from two persons), an error message is displayed by the gate exit display lamp 31 in S62, the gate remains unlocked, the gate is unlocked, and the exit from the two-door box is urged. Then, it is impossible to leave the security area 100 (S68). If the collation is possible, the process proceeds to S63, where the exit history is stored together with the personal information in the entry / exit monitoring means (entrance / exit history memory 10f) of the control unit 10. Thereafter, the electric lock 15 of the gate is unlocked in S64, and the security area is set. Exit from the room 100 is permitted (S65).

Further, after the person desiring to pass through the room, in step S66, the number of occupants calculation means (the number of occupants counter 1)
Referring to 0e), the control unit 10 checks whether the number of occupants in the security area 100 is only one. If there is only one occupant, a warning output device 2
Is activated to output warning information such as urging the occupants to leave the room (S67).

The two-door type entrance / exit permission device 1 as described above,
A security system having a function of managing the number of occupants in a building according to the present invention including a warning output device 2 and a security system 3;
By introducing the security system and forgetting to set the security system, it is possible to prevent or suppress the presence of only one person in the security area 100, and to prevent crime by insiders. In addition, since the entry / exit monitoring means is configured to check the number of persons based on the entry / exit history from the two-door type entry / exit permission device 1 in which entry / exit of only one person is surely performed, the number of persons entering / exiting can be checked. Be more strict. Also,
Since the person who has entered or exited the room can be specified with certainty, it is also possible to know who was alone in the security area 100 and when.

On the other hand, by introducing the security system, the last person who remains in the security area 100 cannot leave the room unless the security system 3 is set. Intrusion, theft, etc. can be prevented.

The number of occupants over time calculated by the occupant number calculation means (occupied number counter 10e) of the control unit 10 causes, for example, when one occupant is present in the security area 100, for example. You can always check if it has become.

The entry / exit permission device is most preferably a two-door type in order to surely collate one entry / exit person, but a single-door entry / exit permission device with a collation device is preferred. It is also possible to adopt.
