Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring system for monitoring buildings, houses, and the like, and more particularly, to a monitoring system in which an access control device for managing traffic at an entrance and a security device for monitoring illegal intruders and the like are integrated.

[0002]

2. Description of the Related Art In a conventional access control apparatus, an electric lock or the like of an entrance door is locked or unlocked only for a person who is permitted to enter or exit a managed building. The identification of the authorized person is performed by collation of information input by an ID card, collation of information input by a fingerprint collation device, and the like. In addition, there is a security device that monitors and guards an entrance and a window of the same building that is managed by the access control device from a security perspective. In the security device, the monitoring target building is placed in a monitoring state, and when an illegal intruder or the like is detected in the monitoring target building, an alarm signal is sent to a remote security center. There is a security release mode in which the security is released and the security center is not notified. In the operation of shifting from the security release mode to the security set mode, the person who exits the last from the monitored building or the like performs a security start operation (hereinafter referred to as “security set operation”), and conversely, from the security set mode to the security release mode. The operation to shift to can be performed by a person who first enters the building performing an operation of releasing security (hereinafter, referred to as a “security release operation”). The security set / security release operation is an important operation for mutually transferring management responsibilities of a monitored building or the like from a user to a security company or from a security company to a user. For this reason, the security set / security release operation can be performed only by a specific person among the users of the monitored building, and the specific transfer operation permitted person is identified by collation of an ID card or fingerprint. I was In the conventional access control device and security device, even the same management / monitoring object is operated independently of each other. This is because a group of authorized persons (including a singular person) that the access control device recognizes as the authorized person of the authorized access and a group of authorized persons that acknowledge that the security device is the authorized transfer operation authorized person ( (Including singularity) does not always match, and furthermore, the registration change manager groups (including singularity) of the respective permitter information may not match. In other words, in the case of an access control device, it is desirable to be able to freely control permission and refusal to enter and exit the entrance and exit for all users to be managed, while security devices are required from the viewpoint of crime prevention.
This is because it is desirable to designate a specific person among the users or a specific person other than the user as the manager and permit the security mode transition operation. In addition, in the access control device, since there is a possibility that the user of the managed object changes relatively frequently, the administrator of the managed object can easily identify the authorized person in order to respond flexibly to increase or decrease. Registration changes and the like can be made. On the other hand, security devices are considered to be operated jointly by the administrator of the monitored object and the security company, and that the shift of the security mode of the monitored object is an important procedure to shift the management responsibility. The procedure for changing the registration of the security mode transition operation permitter requires a stricter and more complicated procedure than the access control device. Therefore, conventionally, the access control device and the security device have been independently installed and operated on the same management / monitoring object.

[0003]

As described above, conventionally,
Although the access control device and the security device were the same control / monitoring target, they were operated independently of each other. For this reason, when an authorized user of a building or the like in the access control device enters from the entrance during the security set mode, there is a problem that the security device determines the user as an intruder and reports an abnormality to the security center. . Some security devices control an electric lock of an entrance door in addition to normal security control. However, in the case of this type of security device, it is necessary to issue an ID card to all users of the monitored object, and it is difficult to limit the transition operators in the security set mode / security release mode. There is a problem that the registration procedure for changing the user becomes complicated. Therefore, the present invention provides a monitoring system that integrates and manages an access control device and a security device, allows a part of information to be shared, and secures the independence of both operations and registration change procedures. The purpose is to:

[0004]

According to the present invention, there is provided a security device having a security set mode for setting a monitoring target in a monitoring state and a security release mode for releasing the monitoring status of the monitoring target. A monitoring system having an access control device for controlling passage permission and rejection of an entrance to and exit from the entrance, wherein the security device is a mode transition operation unit for performing a security mode transition operation, and whether or not the security mode transition operation is permitted. Has a security device communication unit that communicates with the access control device, and a security device control unit that sends security mode information from the security device communication unit to the access control device. The access control device includes a passer-by verification unit that checks whether or not the person is permitted to pass through the entrance, an access control device control unit that controls permission and refusal of access to the entrance, and a communication with the security device. An access control device communication unit that performs access control, and controls traffic permission to the entrance when it is determined that the vehicle is a traffic permitr during the security release mode, and determines that the vehicle is a traffic permitter by the traffic pass verification unit during the security set mode. Then, an authentication code that can be collated by the security device is sent to the security device,
It is possible to solve the problem by a monitoring system characterized in that permission and rejection of traffic to an entrance and exit are controlled in accordance with collation result information received from the security device. According to the monitoring system of the present invention, in the security set mode,
Even if it is determined that the person is a permitted person in the passer-by collation unit of the access control device, the person is checked and controlled by the security mode information from the security device. I ca n’t get into things,
Therefore, the person who is allowed to enter and exit the door is not erroneously detected as an intruder by the security terminal device.

According to a preferred aspect of the surveillance system of the present invention, when the access control device determines that the passer is a permitted person in the security set mode, the access control device compares the security device with the security device by the security device. Send out possible authentication codes. According to this preferred aspect, even in the security set mode, it is possible to give a traffic permit to a person who is permitted to pass through.

According to a preferred aspect of the monitoring system of the present invention, the collation result information is security release mode information. According to this preferred aspect, the security mode information can be used as it is as the collation information.

Further, according to a preferred aspect of the monitoring system of the present invention, the access control device transmits an authentication code that can be collated by the security device to the security device when the access control device determines that the person is a traffic permitter. In the security release mode, if the authentication code input from the access control device within a predetermined time after the security set transition operation in the mode transition operation unit is of a mode transition permitting person, the security set mode information is If the authentication code transmitted to the access control device and received during the security set mode is that of a mode transition permitting person, security release mode information can be sent to the access control device. According to this preferred aspect, only the mode transition permitting person can change the security mode of the security device from the access control device.

Further, according to a preferred aspect of the present invention, there is provided means for converting a pass-permitted person code for specifying a pass-permitted person of the access control device into an authentication code used for collating a mode transition operator of the security device. You can also. By using this conversion means, it is possible to easily realize the setting of the access control device and the security device.

The present invention also relates to a security device used for the monitoring system or an access control device used for the monitoring system.

Have been. The number and types of monitoring systems connected to the central security device 6 are not limited. The monitoring system according to the present invention comprises:
At least one of the monitoring systems a, b, and c
Could be one. The object to be managed and guarded may be the whole or part of an ordinary building (for example, a building, a factory, or a general house), or may be a unit of management and security.
The security object may consist of a plurality of buildings.

FIG. 2 is a block diagram of a monitoring system a according to the present invention. The monitoring system a includes a security device 10
And a fingerprint collation device 2 as an access control device. The security device 10 includes a security terminal device 1 to which an intrusion sensor 4 appropriately disposed on a window or the like is connected in order to detect an intruder into the management / security object A. The fingerprint collation device 2 identifies the user by fingerprint collation, and controls the electric lock 3 at the entrance door to unlock the authorized user (authorized user) if the user is authorized (passenger authorized). Otherwise, keep the locked state and deny passage. Further, as in the embodiment shown in FIG. 2, in the monitoring system according to the present invention, the data converter 7 for maintaining consistency between the data used in the fingerprint collation device 2 and the data used in the security terminal device 1 and the security mode are set. A card reader 8 for reading magnetic card data in which the ID of the transfer operator is stored when the change is made can be provided.

FIG. 3 is a block diagram of a security terminal device 1 that can be used as a security device in the monitoring system of the present invention. The security terminal device 1 communicates with the central security device 6 via the communication line 5 such as a general public line, and a notification unit 17, and communicates with the fingerprint collation device 2 via the card reader 8 and the data converter 7. Local communication I / F 12 that performs
A mode shift operation unit 13 for performing an operation for shifting to the security mode, a sensor I / F 14 for receiving a detection signal from the intrusion sensor 4, and a display unit 15 for displaying current security mode information, presence / absence of abnormality, and the like. , A storage unit 16 comprising a ROM / RAM for storing an operation program of the security system, security mode information, an authentication code (for example, an ID code) for identifying a security mode transition operator, and a CPU for controlling these. And a control unit 11 composed of The mode transition operation unit may be, for example, a key switch, and the display unit may include, for example, an LED.
Or LCD. This security terminal device 1
When a detection signal is received from the sensor 4 via the sensor I / F 14 during the security set mode, an abnormal signal is reported from the reporting unit 17 to the central security device 6 of the security center via the communication line 5.

Here, a security mode transition operation in the security device 10 will be described. First, an operation of shifting from the security release mode to the security set mode will be described. First, the security mode shift operation permitter performs an operation for mode shift, for example, presses a security set operation key on the mode shift operation unit 13. With this security set operation,
In the security terminal device 1, the state of the connected sensor 4 is confirmed, and if there is no sensor in the detection state, a message that the security setting is possible is displayed on the display unit 15. At this time, at the same time as the display, it is preferable to start timing of a predetermined shiftable time (for example, 20 seconds) by a timing means (not shown). On the other hand, if any of the sensors 4 is in the detection state, the fact is displayed on the display unit 15. Here, the detection state of the sensor 4 means that, for example, a window or the like is open and the state should not be shifted to the security set mode state. In this case, processing such as closing the window is made to enable the security setting, and the mode shift operation unit 13 is operated again (for example, the security setting operation key is pressed). At this time as well, it is preferable to start counting the possible transition time in the same manner as described above. The security mode shift operation permitting person who has confirmed on the display unit 15 that there is an indication that the security setting is possible inputs his / her own authentication code. This input can be performed, for example, by operating the ID card in which the self-authentication code is stored from the card reader 8 to input the card data. When the security terminal device 1 receives an authentication code (for example, card data of an ID card) via the local communication I / F 12, the transfer operation authorized person registration table stored in the storage unit 16 (see FIG. 7 described later) ) And verify the authentication code. In the monitoring system of the present invention, the security mode of the security device can be shifted from the security release mode to the security set mode based on the authentication code input from the access control device, which will be described later. .

In the case where an authentication code (for example, card data of an ID card) is not registered in the transfer operation permitted person registration table, or when the security mode cannot be changed even if the authentication code is registered ( After the predetermined settable time elapses from the security setting operation, or after the security setting operation, the mode change is not performed, and the fact is displayed on the display unit 15. On the other hand, if the transition possible time has not elapsed since the security set operation and the authentication code is registered as the transition operation permitter in the transition operation permitter registration table, the security device 10 is switched to the security set mode. At the same time, a security set signal is transmitted from the local communication I / F 12 to the fingerprint collation device 2 and, if necessary, a lock signal is transmitted to the electric lock 3.

On the other hand, the operation of shifting from the security set mode to the security release mode is performed in the same manner as the operation of shifting from the security release mode to the security set mode. It can be implemented by a combination of the key press) and the input of the authentication code. However, since the process of confirming the detection state of the sensor 4 is unnecessary, the mode transition operation unit 13 does not need to perform the mode transition operation, It is preferable that the security mode transition operation permitted person can perform the operation only by inputting his / her own authentication code. As described above, the input of the authentication code can be performed by, for example, operating the ID card on the card reader 8 and inputting the card data of the ID card. When the security terminal device 1 receives an authentication code (for example, card data of an ID card) via the local communication I / F 12, the security terminal device 1 refers to the transfer operation permitted person registration table stored in the storage unit 16 and performs authentication. Check the code. If the authentication code is registered as the transfer operation permitted person in the transfer operation permitted person registration table, the security device 10 is shifted to the security release mode and the security release mode is transmitted from the local communication I / F 12 to the fingerprint collation device 2. Send a signal. At this time, the control unit 11 can also be set to send an unlocking signal to the electric lock 3 at the same time. In the monitoring system of the present invention, the security mode of the security device can be shifted from the security set mode to the security release mode based on the authentication code input from the access control device, and this will be described later.

FIG. 4 shows a fingerprint collation device 2 which is an embodiment of an access control device which can be used in the monitoring system of the present invention.
It is a block diagram of. The fingerprint matching device 2 includes an information input operation unit 2 for inputting information such as registration and deletion of a person who is permitted to enter and exit the doorway.
2, a fingerprint reader 23 for reading fingerprint data, a storage unit 24, a display unit 27 for displaying a security mode and an operation method guidance to an operator passing through the entrance and exit, and a local communication I / O for communicating with the security terminal device 1. F25, an electric lock I / F 26 for controlling opening and closing of the electric lock of the entrance door, and a control unit 21 including a CPU and the like for controlling these. The information input operation unit 22 can be composed of, for example, a numeric keypad, and can also input a personal identification code of an administrator who performs a data registration change operation. The fingerprint reader 23 can be composed of, for example, a camera and a prism. The storage unit 24 is composed of, for example, a ROM / RAM, and stores an operation program, a current security mode, fingerprint data of a person who is permitted to enter and exit, and data for converting the fingerprint data (see FIG. 5 described later). be able to. In addition, the display unit 27 may be formed of, for example, an LED or an LCD.

FIG. 5 shows an entrance / exit permitted person registration table 51 stored in advance in the storage unit 24. The entrance / exit authorized person registration table 51 includes a fingerprint data area 52 for verification. In some cases, a management number area 53 of the fingerprint data for collation and a permission / prohibition data area 54 of entrance / exit traffic can be included. Fingerprint data area for verification 5
2 needs to store at least the fingerprint data of all the authorized persons of the access control device according to the present invention. When a management number is assigned to each of the matching fingerprint data, the management numbers are assigned to the management number area 5.
3 is stored. The management number is a conversion code sent to the data converter 7 and used to replace the security number with the authentication code for the security device, as described later. After being registered as a person who is allowed to enter and exit, the fingerprint data for verification of the person whose traffic is prohibited can be registered as a change in entry / exit prohibition by deleting the fingerprint data for verification itself. In the case of a temporary entrance / exit traffic prohibition measure or the like, it is preferable to perform control by storing control data of prohibition of traffic in the permission / prohibition data area 54.

In the embodiment shown in FIG. 5, for example, a management number 0001 is assigned to the fingerprint data for collation of the user A and registered. Further, since no prohibited data is registered in the permitted / prohibited data area 54 of the user A, entrance / exit traffic is permitted. On the other hand, a management number 0002 is registered for the fingerprint data for verification of the user B, and a prohibition registration is performed in the permission / prohibition data area 54. The prohibition registration is to make a prohibition registration when the user B is no longer a user of the management / monitoring object, so that the registered user B cannot enter the management / monitoring object. It was made.

The registration change of the entrance / exit permitting person registration table 51 can be performed in the same manner as a general fingerprint collation apparatus. An example of the usual method will be briefly described. The data registration change is preferably performed by the person in charge of the management / monitoring object. When registering data, for example, the manager inputs his / her personal identification code at the operation unit 22 and reads his / her fingerprint from the fingerprint reader 23. The control unit 21 compares the input personal identification code and the fingerprint data with the personal identification code and the fingerprint data stored in the storage unit 24, and determines that they are the same. Move to registration mode. In the data registration mode, for example, various data can be registered in accordance with the display on the display unit 27. In this way, the fingerprint collation device 2 can change the registration of the user or the like after recognizing that the person is in charge of managing the management / monitoring target.

FIG. 6 shows a conversion table 61.
1 can be stored in the data converter 7.
The conversion table 61 is a list showing a correspondence between conversion data (for example, a management number) given to each collation fingerprint data and an authentication code (for example, card data of an ID card) used in the security device. is there. In the conversion table 61 shown in FIG. 6, card data corresponding to each of the management numbers stored in the management number area 62 is stored in the card data area 63. For example, in the data converter 7, when the management number “0001” of the user A is transmitted via the local communication I / F 25 of the fingerprint collation device 2, the data converter 7 refers to the conversion table 61 shown in FIG. User A for data
Authentication code (card data of ID card) "abcd
ef ”and transmits the card data“ abcdef ”to the security terminal device 1. Thus, the security terminal device 1
Then, the data specifying the user of the fingerprint collation device 2 can be obtained as card data that is authentication data that can be authenticated by the security terminal device 1. Therefore, even when the security terminal device 1 and the fingerprint collation device 2 use separate and independent data structures, authentication data recognizable by the security device (for example, the security terminal device 1 of the security device 10) is used. ,
Accurate one-to-one compatibility with fingerprint data that can be collated by the access control device (for example, the fingerprint collation device 2) can be ensured. In the embodiment shown in FIGS. 2 to 6, the security terminal device 1 and the fingerprint collation device 2 use different data structures, and the case where the data converter 7 is interposed between them has been described. The same data structure (for example, card data of an ID card or fingerprint data) can be used by the security device and the access control device. In this case,
There is no need to use a data converter.

FIG. 7 shows an example of the transfer operation permitted person registration table 71. The transfer operation permitted person registration table 71 can be stored in the storage unit 16 of the security terminal device 1. In the transfer operation permitted person registration table 71, a card data section 72 for storing recognition data of each user (for example, card data of an ID card), and a person who is permitted to perform a security mode transfer operation are permitted. There is a transfer operation permission / prohibition area 73 for storing a person who does not exist. FIG. 7 shows a user (management number) area 74, which is provided merely for convenience of description, and is not actually included in the transfer operation authorized person registration table 71. Absent.

The transfer operation permitted person registration table 71 is used when determining whether or not the security mode transfer operation is permitted. For example, in the case of the user A who is a user of both the security device and the fingerprint collation device, the card data “abcdef” as the authentication data is registered as “OK” in the transfer operation permission area 73. The card data "ab
When “cdef” is input, it is determined from the transfer operation permitted person registration table 71 that the user A is a permitted person of the security mode transfer operation. Further, for example, users T and U who do not have fingerprint data in the fingerprint collation apparatus can use those card data “gtjnop” and “jyop”.
Since “OK” has been registered for “k”, it is determined that the user is permitted to perform the security mode shift operation. On the other hand, for example, the card data “jkkyop” of the user S is registered as “impossible” in the migration operation permission / prohibition area 73, so if the card data “jkkyop” is input, It is determined that S is not the authorized person of the security mode shift operation. In addition, since the card data of the users B, C, and D having the fingerprint data in the fingerprint collation device are registered as “impossible”, the users B, C,
Even if the card data of D is input from the access control device (for example, the fingerprint collation device) to the security device, it is determined that the person is not the authorized person of the security mode shift operation.

The transfer operation permitted person registration table 71 indicates that the time limit is set only within a predetermined transferable time during which time measurement is started after the mode transfer operation (for example, the operation of pressing the security set operation key) in the mode transfer operation section 13. It is preferable to set the control unit 11 so as to be referred to and used. With this setting, it is possible to prevent the security mode from being shifted even if the authentication code of the authorized shift operation person is input other than within the allowable shift time.

It is preferable that the registration change of the transfer operation permitted person registration table is set so that the person in charge of crime prevention of the management / monitoring object and the employee of the security company cooperate. Specifically, for example, when the security mode of the security device 10 is the security set mode, the security manager of the management / monitoring target shifts the security device 10 to the security release mode. Also,
When the security mode of the security device 10 is the security release mode, it can be determined that there is a security manager at the site of the management / monitoring target, so that the operation by the security manager can be omitted. Next, an employee of the security company operates. For example, an employee of a security company operates an ID card for a security officer on the card reader 8 and inputs card data from the ID card. If the card data is valid, the security terminal device 1 can be changed to the registration change mode. In the registration change mode, the guidance of the registration change operation is displayed on the display unit 15. While watching the guidance, the security manager of the management / monitoring target or an employee of the security company can change the registration of the card data or change the security. It is possible to change the registration of whether or not the mode can be shifted. Therefore, only when the security manager of the control / monitoring object and the employee of the security company agree, the data can be changed, etc., and in other cases, the data cannot be changed. .

Next, in the monitoring system of the present invention, when the security device and the access control device (for example, the fingerprint collation device) are in operation, the access control device (for example, the fingerprint collation device) for the management / monitoring object is operated. The operation in the case where the user performs an unlocking operation on the entrance and exit for the device) will be described with reference to the embodiment shown in FIGS. FIG. 8 is a processing flow of the fingerprint matching device 2. When the user's finger is placed on the fingerprint reader 23, the fingerprint matching device 2 reads the fingerprint data of the user (step S1 in FIG. 8). Then, the fingerprint data for collation registered in advance in the fingerprint data area 52 for collation of the entrance / exit permitted person registration table 51 (FIG. 5) of the storage unit 24 and the fingerprint reader 23
The data is compared with the data from the control unit 21 (step S2 in FIG. 8). If the fingerprint data that matches the input fingerprint data is not registered as a result of the collation, the user is determined not to be a traffic permitter, and a display indicating that collation is not possible (for example, a display of "cannot enter the room") is displayed. It is displayed on the display unit 27 (step S4 in FIG. 8), and waits until the next fingerprint is read. In this case, the electric lock 3 is not unlocked and remains locked. As a result of the collation (step S2 in FIG. 8), even if fingerprint data that matches the inputted fingerprint data is registered, the permission / prohibition data area 54 of the entrance / exit permitting person registration table 51 is registered. If the fingerprint data has been prohibited from being registered, a similar unmatchable display is displayed on the display unit 27 (step S4 in FIG. 8).
Wait for the next fingerprint reading. Also in this case, the electric lock 3
Is not unlocked.

As a result of the collation (step S2 in FIG. 8), fingerprint data that matches the inputted fingerprint data is registered.
If the user has not been registered as a prohibition, it is determined that the user is a traffic permitter, and the process proceeds to the next security set mode determination (step S3 in FIG. 8). In this security set mode determination, the security mode information stored in the storage unit 24 is
It is determined whether or not the security setting mode is set.

In this security set mode determination (step S3 in FIG. 8), if it is determined that the security set mode is not in progress (that is, it is determined that the security is released).
The electric lock 3 is unlocked from the electric lock I / F 26 (step S5 in FIG. 8), and at the same time, regarding the fingerprint data that matches the inputted fingerprint data, the management number area 53 in the entrance / exit traffic permitter registration table 51 (FIG. 5). Is transmitted from the local communication I / F 25 to the data converter 7 (step S6 in FIG. 8). The electric lock 3 is unlocked in response to the unlock control signal, and is automatically locked after a predetermined unlock time has elapsed.

The data converter 7 selects card data corresponding to the management number from the conversion table (FIG. 5), and transmits the card data to the security terminal device 1. Here, the processing flow of the security terminal device 1 that has received the card data is shown in FIG. When receiving the card data (step S21 in FIG. 9), the security terminal device 1 receives the card data within a predetermined shiftable time (for example, within 20 seconds) from the mode shift operation by the mode shift operation unit 13. Is determined (step S22 in FIG. 9). If the received data is within the predetermined transferable time, whether or not the received card data is the card data of the security mode transfer operation permitted person,
The determination is made based on the transfer operation authorized person registration table 71 (FIG. 7) (step S23 in FIG. 9). If it is determined that the user is a mode shift operation permitter, the management / monitoring object is shifted to the security set mode (step S24 in FIG. 9), and the security set signal is transmitted from the local communication I / F 12 to the data converter 7
Is transmitted to the fingerprint collation device 2 via the terminal (step S in FIG. 9).
25).

On the other hand, when it is determined in step S22 in FIG. 9 whether the reception is within the transferable time or not, it is determined that the reception is not within the transferable time. (Step S2 in FIG. 9)
In 3), if it is determined that the user is not the security mode shift operation permitter, the security terminal device 1 does not perform any processing (steps S26 and S27 in FIG. 9). As described above, during the security release mode, the electric lock can be controlled only by the collation result in the fingerprint collation device 2, and when the user wants to shift to the security set mode, the user performs the setting operation in the security terminal device 1, If the fingerprint collation device 2 performs the collation operation within a predetermined time, the security mode transition can be performed only by the person who is permitted to enter the security mode.

Referring again to FIG. 8, the fingerprint collation device 2
Returning to the operation of (1), the fingerprint collation device 2 unlocks the electric lock 3 (step S5 in FIG. 8), and stores the management number in the data converter 7.
(Step S6 in FIG. 8), the security terminal 1
Then, it is determined whether or not the security set signal (see step S25 in FIG. 9) is received within a predetermined time (for example, 3 seconds) (step S7 in FIG. 8). When the security set signal is received, the security set mode is stored in the storage unit 24 (FIG. 8).
Step S8), the display in the security set mode is displayed on the display unit 27, and the process stands by until the next fingerprint reading. On the other hand, if it is determined that the security set signal has not been received within a predetermined time in the determination whether the security set signal has been received (step S7 in FIG. 8), the next security protection state is maintained. Wait for fingerprint reading.

Next, returning to the security set mode determination (step S3 in FIG. 8), if it is determined that the security set mode is in effect in this security set mode determination,
Regarding fingerprint data that matches the entered fingerprint data,

9). The data converter 7 selects the card data corresponding to the management number from the conversion table (FIG. 5) and transmits the card data to the security terminal device 1. Here, the processing flow of the security terminal device 1 that has received the card data is shown in FIG. Upon receiving the card data (step S31 in FIG. 10), the security terminal device 1 determines whether or not the received card data is the card data of a security mode transition operation permitter by a transition operation permitter registration table 71 (FIG. 10). 7) (step S32 in FIG. 10). If it is determined that the user is a mode shift operation permitter, the management / monitoring object is shifted to the security release mode (step S33 in FIG. 10), and
A security release mode transition signal is transmitted from the local communication I / F 12 to the fingerprint collation device 2 via the data converter 7 (step S34 in FIG. 10). On the other hand, it is determined whether or not the user is a security mode shift operation permitting person (step S32 in FIG. 10).
If it is determined that the user is not a security mode shift operation permitter, the security terminal device 1 does not perform any processing (step S35 in FIG. 10).

Referring again to FIG. 8, the fingerprint collation device 2
Returning to the operation of the above, the fingerprint collating apparatus 2 transmits the management number to the data converter 7 (step S9 in FIG. 8), and shifts from the security terminal device 1 to the security release mode within a predetermined time (for example, 3 seconds). It is determined whether a signal (see step S34 in FIG. 10) has been received (step S10 in FIG. 8). When the security release mode transition signal is received, the electric lock I / F
The electric lock 3 is unlocked from 26 (step S11 in FIG. 8).
Then, the security release mode is stored in the storage unit 24 (Step S12 in FIG. 8), and the display in the security release mode is displayed on the display unit 27, and then the process stands by until the next fingerprint reading. Electric lock 3
Is unlocked in response to an unlock control signal, and is automatically locked after a predetermined unlock time has elapsed. On the other hand, it is determined whether a security release mode transition signal has been received (step S10 in FIG. 8).
If it is determined that the security release mode transition signal has not been received within a predetermined time, a display indicating that the verification is impossible is displayed on the display unit 27 (step S4 in FIG. 8), and the process waits until the next fingerprint is read. . In the security terminal device 1,
Judgment as to whether or not the received card data is card data of a person permitted to enter the security mode (step S3 in FIG. 10)
In 2), when it is determined that the user is a mode change operation permitter, the security terminal device 1 transmits a security release mode change signal to the fingerprint collation device 2 from the local communication I / F 12 (step S34 in FIG. 10). ), It can be set to transmit an unlock control signal for the electric lock 3 at the same time.

As described above, during the security set mode,
Only after the verification result in the fingerprint verification device 2 and the confirmation of the security mode shift operation permitted person in the security terminal device 1 can the electric lock be controlled. Only a registered person who is registered in advance as a security mode shift operation permitting person of the security device can shift the security mode and unlock the electric lock 3. In other words, other persons cannot unlock the electric lock 3, and as a result, cannot enter the object to be managed / monitored. Will not be erroneously detected as an intruder.

In the above embodiment, the data converter 7 is interposed between the security end device 1 and the fingerprint collation device 2. However, a device having the same function as either the security terminal device or the fingerprint collation device is used. It can also be configured by incorporating. Also,
In the above embodiment, the information exchange between the security terminal device 1 and the fingerprint collation device 2 is realized by transmitting and receiving the security mode signal, but the mode of the information exchange is not limited to this. That is, in the present specification, “communication” means transmitting a state to another (that is, communication in a broad sense). For example, only communication by an output signal (for example, security mode information or unlock / lock control signal) is performed. In addition, communication by voltage or current of the relay contact state is also included. Specifically, for example, the security terminal device is directly connected to the fingerprint collation device, and a relay contact is provided in the security terminal device. In the security terminal device, control is performed according to the security mode, for example, to short-circuit the relay contact in the security set mode and to open the relay contact in the security release mode. On the other hand, the security mode may be recognized by monitoring the state of the relay contact with a fingerprint or collation device using current or voltage. In this case, it is not always necessary to store the security mode in the fingerprint matching device. In this specification, it should be understood that such a method of recognizing the security mode using the relay contact is also included in one type of the communication method. Further, in the above embodiment, the case where the security mode signal and the control signal of the electric lock are separately transmitted is mainly described. However, the security mode information and the control signal of the electric lock are added to one signal. Can also. In the above embodiment,
Although the case where the fingerprint collation device is used as the access control device has been described, the access control device is not limited to this, and a magnetic card, an IC card, or various biometric information (for example, retina) verification devices may be employed. it can. Furthermore,
In the above embodiment, the electric lock is exemplified as the means for controlling the entrance of the management / monitoring object, but the entrance control means is not particularly limited, and may be, for example, an automatic door or an elevator.

[0035]

As described above, in the surveillance system according to the present invention, the entrance control can be freely controlled by the access control device in the security release mode, and the control of the entrance in the security set mode can be restricted. it can. For this reason, a legitimate user of the access control device cannot be mistakenly entered during the security set mode, and is not detected as an intruder by the security device. In addition, with the access control device according to the present invention, only the user of the management / monitoring object can easily and flexibly change the registration of the user.
