Description

  The present invention relates to a security mode for a monitoring target, a warning mode for performing abnormality monitoring when the monitored area is unattended, a release mode for not performing abnormality monitoring, and a coordinator dispatched for coping with the monitoring target. The present invention relates to a security system capable of switching a countermeasure mode to be used.

  In the security system, in addition to a warning mode and a release mode, a response mode that is set during a response operation, such as a patrol mode for the security guard to perform an abnormal check, and a maintenance mode for the security guard or maintenance worker to perform a periodic check, etc. Is provided.

  A user of a property such as a building to be monitored possesses a unique user card for each property or for each user, and operates the card as necessary when entering or leaving the building. Switch.

  On the other hand, the countermeasure mode can be set by a countermeasure card possessed by the guard. A handling card is prepared for each property, and stored together with the property key in a waiting place or mounted on a handling vehicle having jurisdiction over the area. The security guard who has received a handling instruction from the monitoring center has the property key and the handling card in the waiting area or the handling vehicle, heads for the handling location, switches the security mode to the handling mode, and checks the inside and outside of the building for abnormalities. .

  Here, as shown in Prior Art Document 1, a method is known in which a password (password) can be used to switch to a handling mode instead of a handling card. Also, as shown in Prior Art Document 2, as a countermeasure when a password is leaked to a third party, a temporary usable password is issued at the monitoring center and the alert mode is canceled using this password. A system has also been proposed.

  Hereinafter, embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a schematic configuration of a security system 2 according to the first embodiment. The security system 2 includes a security device 4, a communication network 6 and a monitoring center 8, and the security device 4 is connected to the monitoring center 8 via the communication network 6. The security device 4 is basically installed for each property to be monitored, and a plurality of security devices 4 can be connected to the monitoring center 8.

  Although not shown in FIG. 1, a user card used when a user such as a building to be monitored switches a security mode that is an operation mode of the security device 4 also constitutes a part of the security system 2. Further, a coping person who performs a coping operation regarding the security device 4 switches a security mode of the security device 4 to a mode (coping mode) for the coping operation (corresponding card). Part of it.

  The security device 4 includes a sensor 10, an operation display unit 12, a reader unit 14, a notification unit 16, a communication unit 18, a storage unit 20, and a control unit 22. The sensor 10, the operation display unit 12, the reader unit 14, the notification unit 16, the communication unit 18, and the storage unit 20 are connected to the control unit 22 by wire or wirelessly.

  The sensor 10 is a device that detects an abnormality in the monitoring area. For example, the image monitoring sensor includes a camera and an image processing device, a human sensor that detects a human body by a change in infrared rays, fire, smoke, and the like. Such as a sensor. An output signal of the sensor 10 is input to the control unit 22.

  The operation display unit 12 includes a touch panel display. On the display, an operation guide for the security device 4 and a monitoring image are displayed from the control unit 22. The touch panel is an input means for a user or the like to perform various operations on the control unit 22. The input means is used, for example, for inputting a password (password: PW) and for switching the security mode. The operation display unit 12 may include other input means such as buttons, switches, and numeric keys.

  The reader unit 14 is a device that reads information recorded on a user card or a handling card. For example, the user card or the handling card is a non-contact type IC card in which authentication information or the like is recorded. In this case, the reader unit 14 is a non-contact type IC card reader, and reads information from the tricked card and controls the control unit 22. Output to.

  Since the operation display unit 12 and the reader unit 14 are operated at the time of entering or leaving the building to be monitored, the operation display unit 12 and the reader unit 14 are basically installed near the entrance of the building. The installation location may be inside or outside the entrance / exit. Further, the operation display unit 12 and the reader unit 14 can be configured as one module. In addition to the entrance / exit of the building, one reader unit 14 may be provided for each room boundary (area boundary) in the building. In this case, the user operates the reader unit 14 when entering and exiting the building and moving between areas.

  The notification unit 16 is a speaker or the like that outputs an alarm when an abnormality is detected, and operates based on an output signal from the control unit 22.

  The communication unit 18 is a communication interface between the control unit 22 and the monitoring center 8.

  The storage unit 20 stores various programs executed by the control unit 22 and necessary data. In particular, the storage unit 20 stores a property code 30 unique to each property to be monitored, user identification information (user ID 32), and identification information for handling work (handling ID 34). In addition, the storage unit 20 temporarily stores a password (handling PW 36) generated for handling work described later. The storage unit 20 also stores the currently set security mode 38, the currently occurring abnormal state, the sensor detection history, and the like. Furthermore, the memory | storage part 20 matches with user ID, and memorize | stores the occupancy state 40 of the user of the said ID. In the present embodiment, the storage unit 20 stores user qualification information 42 in association with the user ID.

  The occupancy state 40 is information indicating the presence or absence of the user in the monitoring target area, and indicates whether the user is in the monitoring target area or not. In the present embodiment, the presence state is expressed as “present” and the absence state is expressed as “absent”. In addition, information indicating where the user is in a plurality of areas such as in the building to be monitored may be stored as the presence state.

  The qualification information 42 is used to determine whether or not to switch to the handling mode with a password, which will be described later. For example, the qualification information 42 can store the position of each user in an organization such as a company and the position that allows the dispatched staff to respond. Further, the qualification information 42 may simply store the presence or absence of a qualification that allows switching to the handling mode.

  The control unit 22 is configured using a microprocessor or the like, and functions as an abnormality monitoring processing unit 50, a mode management unit 52, a password (PW) generation unit 54, an occupancy management unit 56, and the like according to a program to be executed.

  The abnormality monitoring processing unit 50 determines the occurrence of various abnormal events in the monitoring target and the security device 4. Abnormal events include, for example, detection of an intruder based on a detection signal from the sensor 10 (intrusion abnormality), a situation in which an emergency operation signal is issued by the operation display unit 12 or an emergency button (emergency abnormality), and security of the sensor 10 or the like. There is a situation (device abnormality) in which a detection signal such as a failure of the device of the device 4 is issued. If the abnormality monitoring processing unit 50 determines that there is an abnormality, it notifies the monitoring center 8 of the detected abnormality content together with the property code. In addition, the notification unit 16 may be operated to notify the abnormality report.

  The mode management unit 52 controls the switching of the security mode, and switches the security mode only when it is determined that the security mode switching operation for the security device 4 is appropriate. The mode management unit 52 stores the currently set security mode in the storage unit 20 and transmits it to the monitoring center 8.

  The guard device 4 basically has three guard modes: a guard mode, a release mode, and a countermeasure mode. The alert mode is a state in which an abnormality is monitored when the user is selected and set in a state in which the user leaves the area to be monitored and is unattended, and the area to be monitored is unattended. Specifically, abnormality monitoring including intrusion abnormality by the sensor 10 is performed. In the alert mode, when an abnormality occurs, a report is sent to the monitoring center 8 and a guard is dispatched to the property that is the report source.

  On the other hand, the release mode is a state in which the abnormality monitoring in the state of being unattended is released, and the sensor 10 is stopped or the intrusion detection signal is invalidated. The release mode is selected and set in a state where a user can exist in the monitoring target area. Incidentally, even in the release mode, if an emergency operation signal or a device abnormality detection signal is issued, a notification is sent to the monitoring center 8 and a security guard is dispatched to the property from which the notification was made.

  The coping mode is used by a person (cooperator) dispatched to coping work in a monitored property such as a security guard or a maintenance worker. During the countermeasure mode, the detection history of the sensor 10 is recorded in the storage unit 20, but abnormality determination / notification is not performed. For example, the countermeasure mode is used in an abnormal inspection performed by a guard visiting the property in charge or an abnormal inspection performed in response to a request from the monitoring center 8 when an abnormality occurs. Incidentally, in the abnormality check, for example, confirmation of an abnormality history recorded in the storage unit 20, confirmation of an alarm sensor and an alarm location, and the like are performed. The countermeasure mode is also used when the security device 4 is regularly inspected. Specifically, addition / deletion of the user ID registered in the security device 4 and other various setting changes are performed using the countermeasure mode at the time of system introduction and thereafter as needed. Also, maintenance, operation test, replacement, etc. of devices such as sensors are performed in the countermeasure mode.

  When switching the security mode, the mode management unit 52 authenticates the operator, confirms the authority given to the operator, and performs only switching within the authority. The user card and the handling card described above are used for the authentication. In these cards, a card ID is stored as card information serving as authentication information. For example, a user ID (user authentication information) that is a combination of a property code and a code (serial number or the like) that identifies a user in the property is stored as a card ID in the user card. In addition, the handling card stores a handling ID consisting of a combination of a property code and a code indicating that it is not a user's card but a handling work card as a card ID.

  Here, the coping card is an authentication medium that can maintain security as in the case of the user card. Here, this is called a specific authentication medium. Specifically, the coping card is a unique authentication medium for each property to be monitored. In this respect, security is ensured compared to a so-called master key authentication medium that can operate multiple properties in common with a single card. Is easy. The coping card is possessed only by a limited number of coping personnel (specific coping personnel). For example, a handling card for a certain property is placed in a waiting area or a handling vehicle for a coordinator in charge of the property, and a counselor who is not in charge does not basically have a handling card. In this respect, security can be ensured.

  In the security system 2 according to the present invention, authentication information for the coping work used in the mode management unit 52 is generated by the PW generation unit 54 separately from the authentication information (first authentication information) stored in the coping card. Password is used. The password is basically intangible information and is used without going through a tangible authentication medium. In this respect, the password is authentication information (second authentication information) that can be given to an arbitrary coordinator, unlike the first authentication information recorded on the specific authentication medium that is a tangible “thing”. is there. For example, by using a communication means to inform the counselor who is close to the property to be monitored or the counselor who is available, the countermeasure can be started quickly and the waiting time of the property user can be reduced. Is possible.

  Here, the second authentication information such as a password is highly convenient, but has a problem that security is lowered. The mode management unit 52 restricts the switching of the security mode based on the second authentication information more than the first authentication information, thereby achieving both maintenance of security and quick response. Details of the control by the mode management unit 52 will be described later.

  The PW generation unit 54 generates a one-time password (temporary PW) as the above-described password for handling work (handling PW). For example, a password such as a personal identification number is generated according to a predetermined rule using the current time and the property code every predetermined time such as an interval of 30 minutes. Also, a new handling PW is generated even when the handling PW is used once. The generated countermeasure PW is temporarily stored in the storage unit 20, and when a new countermeasure PW is generated, the old countermeasure PW is deleted from the storage unit 20.

  The occupancy management unit 56 has a function as a presence / absence determination unit that determines the presence / absence of the user in the monitored area. The occupancy management unit 56 can determine the presence / absence based on the user authentication information read from the user card. The occupancy management unit 56 authenticates the user authentication information, and performs unlocking control of the door with the electric lock and opening control of the automatic door. Specifically, the occupancy management unit 56 collates the user ID read from the user card trapped by the reader unit 14 with the user ID 32 registered in advance in the storage unit 20. When the read user ID matches the registered user ID 32, the user ID is recognized as a traffic request, and traffic restriction means such as an electric lock is released. At the same time, the occupancy management unit 56 updates the occupancy status 40 of the user ID to “occupied” or “absent”. For example, it is possible to determine whether to move into the building (entrance) or to move out of the building (exit) depending on which of the reader cards 14 installed outside or inside the entrance / exit is deceived by the user card. Similarly, the movement source and the movement destination can be determined by movement between areas. Therefore, for example, if the user enters the building or moves within the building, the occupancy management unit 56 sets the occupancy state 40 to “in-room” (or “area” of the destination as information indicating “in-room”). Information), and if the user leaves the building, the occupancy state 40 is updated to “absent”.

  The monitoring center 8 is connected to a plurality of security devices 4 via the communication network 6. Specifically, the monitoring center 8 is provided with a monitoring table including an operation unit 60, a display unit 62, a communication unit 64, a storage unit 66, a control unit 68, and the like as a monitoring center device. The operation unit 60, the display unit 62, the communication unit 64, and the storage unit 66 are connected to the control unit 68.

  The operation unit 60 is a means for an operator (controller) of the monitoring center 8 to input various settings, information, instructions, and the like to the control unit 68. Examples of the operation unit 60 include a keyboard, a pointing device, and buttons.

  The display unit 62 is an image display unit such as a liquid crystal display, and displays an image from the sensor 10, an abnormality detection signal, a security mode of the property, presence / absence of abnormality detection, and the like.

  The communication unit 64 is a communication interface between the control unit 68 and the security device 4.

  The storage unit 66 stores various programs executed by the control unit 68 and necessary data.

  The control unit 68 is configured using a microprocessor or the like, and controls the operation of each unit of the monitoring center apparatus according to a program to be executed.

  For example, when the control unit 68 receives an abnormality report from any of the security devices 4, the control unit 68 displays the content of the abnormality and information related to the property on the display unit 62 as handling information. The controller confirms the displayed countermeasure information, selects an appropriate person in consideration of the status of the handler, and instructs the person to deal with the situation.

  The monitoring center device can be provided with a management function for coping personnel. For example, the status (such as the handling status) of the coordinator who belongs to each security service provision area is managed. Also, in the monitoring center device, a waiting place in which the key of each property and a handling card are stored and a mounted handling vehicle are registered and associated with the handling staff status.

  The management function may include a function that supports a handling instruction to the handling staff. For example, based on the countermeasure information, the monitoring center device extracts a coordinator who is using the vehicle loaded with the coping card for the property as a counselor candidate and displays it together with the status of the counselor. In addition, the coordinator waiting at the waiting place where the coping card of the same property is stored is displayed together with the status. Furthermore, in addition to the coping staff who can carry these coping cards, the status of coping staff belonging to the corresponding area and adjacent areas can be displayed. The controller selects an appropriate cooperator in consideration of the priority of coping, and transmits coping instruction information including property information and abnormality content to the portable terminal possessed by the counselor.

  Furthermore, the monitoring center device has a function of generating a password and notifying a coping person. Specifically, a temporary PW for handling is generated based on the property code of the handling destination and the current time. When the controller transmits the handling instruction information or receives an arrival notification indicating that the handling property has arrived from the coordinator's mobile terminal, the controller generates and displays a temporary PW as necessary. Send to the coordinator's mobile terminal. For example, the monitoring center device refers to the status of the coordinator who instructed the coping, and when the coping man is not linked to the vehicle with the corresponding coping card or the storage stand-by, the coping without the coping card described later To make it possible, a temporary PW is issued. In addition, the temporary PW can be updated by the operation of the controller at the end of the handling. Note that the controller may be notified of the temporary PW by telephone or wireless.

  Also in the security device 4, the same password is generated synchronously by the PW generator 54 with the same algorithm as the monitoring center 8. Therefore, the monitoring center device itself may not generate a password, but may acquire the password generated by the PW generation unit 54 from the security device 4.

  Next, security mode control in the security system 2 will be described. Table 1 is a table summarizing security mode transition processing, and shows the mode transition permitted for each mode switching operation method for each current security mode (current mode). The “operation method” is an operator authentication means when switching the security mode, and the user of the property performs authentication using a user card. For coping personnel, there are two types of authentication means: coping card and coping PW.

  FIG. 2 is a flowchart showing an outline of processing when the current mode is the alert mode or the release mode.

  The mode management unit 52 waits until an authentication operation for switching the security mode is performed (a loop process including the case of “No” in steps S2 to S6), and corresponds to the operation when the authentication operation for switching the security mode is performed. Processing is performed (in the case of “Yes” in any of steps S2 to S6).

  Specifically, as a switching operation when the current mode is the alert mode or the release mode, an operation with a user card (S2), an operation with a countermeasure card (S4), and an operation with input of a countermeasure PW (S6) are possible. is there.

  When the user card is deceived by the reader unit 14, the mode management unit 52 verifies the user ID read from the user card against the user ID 32 of the storage unit 20 and authenticates the user ID. If the authentication is successful, it is determined that an operation with the user card has been performed (“Yes” in S2). If the current mode is the warning mode, the mode is switched to the release mode. If the current mode is the release mode, the warning mode is set. (Step S8).

  In addition, when the mode is switched by the user card, the operation display unit 12 allows the operator to input an instruction to switch between the warning mode and the release mode, and confirms the operator's intention to prevent an erroneous operation. Also good. Further, the confirmation operation may be performed only when the warning mode is set.

  After switching by the user card, the mode management unit 52 returns to step S2 and continues the processing in the alert / cancel mode shown in FIG.

  When the handling card is trapped by the reader unit 14, the mode management unit 52 compares the handling ID read from the handling card with the handling ID 34 of the storage unit 20 and authenticates. If the authentication is successful, it is determined that an operation using the countermeasure card has been performed (in the case of “Yes” in S4), and the security device 4 is shifted to the countermeasure mode regardless of whether the current mode is the alert mode or the release mode ( Step S16). With the switching, the mode management unit 52 ends the processing in the alert / release mode shown in FIG. 2 and starts the processing in the handling mode shown in FIG.

  When the coping PW is input on the operation display unit 12 (in the case of “Yes” in step S6), the mode management unit 52 is in the release mode (in the case of “Yes” in step S10), If the occupancy status 40 of a user having specific qualification information 42 (hereinafter referred to as a specific user) is “in-room” (or “area” information) (“Yes” in step S12), input The handled PW is collated with the temporary PW stored in the storage unit 20 (the handled PW 36). Then, when the handling PW matches (in the case of “Yes” in step S14), the mode management unit 52 shifts the security device 4 to the handling mode (step S16). At this time, it is stored in the storage unit 20 that it is the countermeasure mode (the countermeasure mode with PW) set by the input of the countermeasure PW. With the switching, the mode management unit 52 ends the processing in the alert / release mode shown in FIG. 2 and starts the processing in the handling mode shown in FIG.

  On the other hand, when the handling PW input operation is performed in the alert mode (“No” in step S10), the handling PW input operation is performed in the absence of the specific user (in step S12). If “No”) and the input countermeasure PW does not match the temporary PW stored in the storage unit 20 (“No” in step S14), the mode management unit 52 is in the guard mode. The current mode is maintained on the assumption that the transition to (step S18) has failed. Since the current mode is maintained, the mode management unit 52 returns to the loop process of steps S2 to S6 and continues the process in the alert / release mode.

  Incidentally, the input operation of the coping PW itself may be rejected in the alert mode or in the absence of the specific user. For example, in the release mode and when the specific user is in the room, the operation menu displayed on the touch panel display of the operation display unit 12 is provided with an option for accepting the input of the coping PW, whereas the warning mode and absence It is possible to adopt a configuration in which the option is not displayed in the state.

  As described above, during the alert / release mode used by the user, the user card can be switched between the modes, and the cooperator can be switched to the coping mode. To do. When the counselor possesses a coping card with higher security than the coping PW, switching to the coping mode is permitted not only in the presence state of the user in the property but also in the absence state. Thereby, the coping person can perform various coping operations including intrusion abnormality. On the other hand, the setting of the handling mode by the handling PW is a function that is mainly required in a situation where a user is a monitoring target, with the main purpose of practicing quick handling in response to a user request. . Therefore, by making it possible to set the response mode by using the response PW without the need for a response card only for the presence status of users (especially users who have the authority to respond to the response personnel), various setting changes and device inspection / A quick response to a user's request such as exchange, and securing of security in a warning mode when the user is absent are suitably realized.

  Here, basically, when the user is in the room, the security mode is the release mode. On the other hand, even in the release mode, the user is not always in the room. The determination may be omitted, and it may be configured to determine whether or not to check the coping PW (S14) based on the presence / absence of the user (S12) regardless of the security mode.

  For example, there is a monitoring mode in which a warning mode (partial warning mode) is set for a part of the monitoring target such as the outer periphery of the building when there is a user in the building. In this mode, the partial warning mode can be treated as a kind of the warning mode in the determination in step S10, while the partial warning mode is based on the assumption that the user is in the room and is in the release mode. It can also be handled in the same way.

  FIG. 3 is a flowchart showing an outline of processing when the current mode is the coping mode.

  The mode management unit 52 waits until an operation for switching the security mode is performed (a loop process including “No” in steps S30 and S32). When an operation for switching the security mode is performed, a process corresponding to the operation is performed. (Yes in any of steps S30 and S32)

  Specifically, as the switching operation in the case where the current mode is the countermeasure mode, either an operation by the countermeasure card (S30) or an operation by input of the countermeasure PW (S32) is possible.

  When the handling card is trapped by the reader unit 14, the mode management unit 52 compares the handling ID read from the handling card with the handling ID 34 of the storage unit 20 and authenticates it. If the authentication is successful, it is determined that the operation using the countermeasure card has been performed (in the case of “Yes” in S30), and the operation display unit 12 instructs the operator to switch between the warning mode and the release mode. Let If the instruction is a request to shift to the release mode (“Yes” in S34), the mode management unit 52 places the security device 4 in the release mode (step S36), while the instruction shifts to the warning mode. If the request is to be made (in the case of “No” in S34), the security device 4 is set to the warning mode (step S38). As the countermeasure mode ends, the mode management unit 52 ends the process of FIG. 3 and starts the process in the alert / cancel mode shown in FIG. Note that the countermeasure card can be switched only to the alert mode, and the user card may be required to switch to the release mode.

  When the coping PW is input on the operation display unit 12 (“Yes” in step S32), the mode management unit 52 sets the coping mode (coping mode with PW) in which the current mode is set by inputting the coping PW. If so (if “Yes” in step S40), the input countermeasure PW is collated with the temporary PW stored in the storage unit 20 (the countermeasure PW36). If the coping PWs coincide (“Yes” in step S42), the mode management unit 52 shifts the security device 4 to the release mode (step S36).

  On the other hand, when the current mode is the coping mode set by the coping card (in the case of “No” in step S40), or when the inputted coping PW does not match the temporary PW stored in the storage unit 20 ( In the case of “No” in step S42, the mode management unit 52 maintains the coping mode assuming that the transition to the security mode has failed (step S44), and returns to step S30.

  Note that the determination process in step S40 is omitted, and it is possible to shift to the release mode by the handling PW regardless of whether the handling mode of the current mode is set by either the handling card or the handling PW.

[Second Embodiment]
Hereinafter, regarding the security system 2b according to the second embodiment of the present invention, the same components as those in the first embodiment are denoted by the same reference numerals, and the description in the first embodiment is used here. The description will be simplified, and the difference between the security system 2b of the second embodiment and the first embodiment will be mainly described.

  The schematic configuration of the security system 2b is the same as that shown in FIG. 1 for the security system 2 of the first embodiment. In this embodiment, when the monitoring center 8 dispatches a counselor who does not have a coping card to the coping work of the property, the monitoring center 8 performs coping work with the coping PW with respect to the security device 4 of the coping destination. A countermeasure command is transmitted as countermeasure approval information indicating approval. Specifically, the control unit 68 issues a countermeasure command to the security device 4 in response to the operation of the controller.

  The security device 4 receives the handling command via the communication network by the communication unit 18 and stores the handling command in the storage unit 20. In order to prevent the issued countermeasure command from being used in the alert mode, in the present embodiment, the storage of the received countermeasure command in the storage unit 20 of the security device 4 is temporarily limited. The holding time of the handling command in the storage unit 20 can be a predetermined time (for example, 10 minutes) or a time specified by the handling command.

  The mode management unit 52 of the security system 2b allows switching to the handling mode by the handling PW on condition that the occupancy state 40 of the specific user is “in-room” and the handling command is stored. This is different from the first embodiment. Referring to the flowchart of FIG. 2, in the first embodiment, when the handling PW is input (in the case of “Yes” in S6), the mode management unit 52 performs authentication by the handling PW (in S14). In the case of “Yes”), the security mode is the release mode (in the case of “Yes” in S10) and the occupancy status 40 of the specific user is “ ”(In the case of“ Yes ”in S12), but in this embodiment, it is an additional condition that the handling command is stored in the storage unit 20. When the condition is satisfied, the mode is shifted to the handling mode (S16), and when the handling command is not stored, the mode is not shifted (S18).

  Note that the determination in step S10 can be omitted as in the first embodiment. Further, the processing at the time of operation by the user card and the handling card in the alert / release mode is the same as the processing of the first embodiment described with reference to FIG. 2, and the processing in the handling mode has been described with reference to FIG. This is the same as the processing in the first embodiment.

  As the handling approval information sent from the monitoring center 8, a temporary PW generated by the monitoring center 8 using the same algorithm as the PW generating unit 54 of the security device 4 can be used. In this case, when the temporary PW generated by the PW generation unit 54 matches the temporary PW received from the monitoring center 8, the security device 4 allows the shift to the response mode by inputting the response PW for a predetermined time.

  Further, the security device 4 may store the temporary PW received from the monitoring center 8 for a predetermined time (for example, 10 minutes) without generating the temporary PW. As in the first embodiment, the coping person receives the temporary PW generated by the monitoring center 8 as the coping PW and inputs it to the security device 4. Therefore, in step S14 shown in FIG. 2, the mode management unit 52 collates the input countermeasure PW with the temporary PW received from the monitoring center 8 by the security device 4, and allows the transition to the countermeasure mode if they match. .

[Third Embodiment]
In the following, the security system 2c according to the third embodiment of the present invention uses the same reference numerals for the same components as those in the first embodiment, and uses the description in the first embodiment. The description will be simplified, and the differences between the security system 2c of the third embodiment and the first embodiment will be mainly described.

  The security system 2c has a configuration in which an electric lock is added to the configuration shown in FIG. The electric lock is installed on a door of the property and is locked / unlocked by an electric signal from the control unit 22.

  FIG. 4 is a flowchart showing an outline of processing when the current mode in the present embodiment is the alert mode or the release mode. In FIG. 4, steps that are the same as those in FIG. 2 are given the same reference numerals. The mode management unit 52 is different from the first embodiment in that the electric lock control is interlocked when the mode is switched by the authentication using the user card or the handling card.

  For example, when the mode management unit 52 determines that the authentication with the user card is successful and the operation with the user card has been performed (“Yes” in S2), the mode management unit 52 switches the security mode from the security mode to the release mode. The electric lock is unlocked for a predetermined time (for example, 10 seconds) to allow the user to enter the building. Here, when the door transitions from the open state to the closed state, the electric lock is automatically locked again.

  In addition, when the mode management unit 52 determines that the authentication with the countermeasure card has succeeded and the manipulation with the countermeasure card has been performed (“Yes” in S4), the countermeasure is taken regardless of whether the current mode is the alert mode or the release mode. Although the mode is set to be shifted (step S62), the electric lock is unlocked for a certain period of time together with the shift set to the countermeasure mode, and the counselor is allowed to enter the building (step S64).

  The processing in other cases in the alert / release mode is the same as the processing in the first embodiment described with reference to FIG. That is, when the countermeasure PW shifts to the countermeasure mode (step S16), the electric lock is not linked and is not unlocked. The determination in step S10 can be omitted as in the first embodiment.

  Note that the processing in the handling mode is the same as the processing of the first embodiment described with reference to FIG.

  According to this embodiment, in a system configuration in which card authentication and electric lock control are linked, it is possible to set a handling mode without a handling card only in the presence state of the user, and if there is no handling card, the user's response Since admission without permission is restricted, it is possible to respond quickly to user requests and secure security.

  The features of this embodiment can also be applied to the security system 2b of the second embodiment.

[Fourth Embodiment]
In the following, the security system 2d according to the fourth embodiment of the present invention is given the same reference numerals for the same components as those in the first embodiment, and the description in the first embodiment is used here. The description will be simplified, and the difference of the security system 2d of the fourth embodiment from the above embodiment will be mainly described.

  The schematic configuration of the security system 2d is the same as that shown in FIG. 1 for the security system 2 of the first embodiment. This embodiment is common to the second embodiment in that a countermeasure command is transmitted from the monitoring center 8 to the security device 4. The main difference between this embodiment and the second embodiment is that the control unit 68 of the monitoring center 8 is limited to the case where the security device 4 to be dealt with is in the release mode and the presence of the user is detected. And issue a countermeasure command.

  Specifically, in the security device 4, the mode management unit 52 transmits the currently set security mode to the monitoring center 8, and the occupancy management unit 56 indicates the current occupancy state 40 of the specific user. 8 to send. In the monitoring center 8, the control unit 68 issues a countermeasure command to the security device 4 in response to the operation of the controller. At that time, the control unit 68 refers to the current security mode and occupancy state of the security device 4 stored in the storage unit 66, the security device 4 to be dealt with is set to the release mode, and the specific use is further performed. When the person's occupancy state 40 is “in-room”, the issue of the countermeasure command is permitted. On the other hand, even in the release mode, if the occupancy state 40 of the specific user is “absent” or is set to the alert mode, the issuance of the countermeasure command is prohibited.

  The coping command of the present embodiment is issued after the monitoring center 8 confirms that the security device 4 is in the release mode and the occupancy status 40 is “occupied”. In the process of switching to the handling mode by the handling PW in the / release mode, it is determined whether or not the mode is the release mode shown in FIG. The determination is made as to whether or not the handling command is stored in the storage unit 20. That is, with reference to the flowchart of FIG. 2, when the handling PW is input (in the case of “Yes” in S6), the mode management unit 52 stores the handling command in place of steps S10 and S12. 20 is determined. When the countermeasure command is stored, if the countermeasure PW matches (if “Yes” in S14), the mode management unit 52 shifts the security device 4 to the countermeasure mode (S16). On the other hand, if no coping command is stored, mode transition is not performed (S18).

  Note that, as a configuration corresponding to the configuration in which the determination in step S10 described in the first embodiment is omitted, the monitoring center 8 has the occupancy state 40 regardless of whether the security mode is the security mode or the release mode. If it is “in the room”, it may be configured to allow issuing of a countermeasure command.

[Modification]
(1) In the above embodiment, the configuration example in which the first authentication information unique to the monitoring target is recorded and the countermeasure card is used as an example of a specific authentication medium possessed only by a limited number of the countermeasure members has been described. . However, the specific authentication medium may be other items prepared for each property, and for example, a mobile terminal that communicates with the security device 4 or an RFID tag can be used.

  (2) In the above embodiment, the configuration example in which the handling PW is used as the second authentication information that can be given to any coping staff has been described. However, the second authentication information is not limited thereto, and for example, gestures, biometric information used for biometric authentication, and the like can be used.

  When using biometric authentication, the biometric information of the coping person is registered in the monitoring center 8 in advance. Then, when the monitoring center 8 instructs the coping person to deal with, the biometric information of the coping person is notified to the security device 4, and the security device 4 may temporarily store this in the storage unit 20 for authentication.

  In addition, data recorded on a common handling card (so-called master-type authentication medium) that is not unique to each property and can be used in a plurality of properties is used as second authentication information, and each coping member possesses the common handling card. It can also be configured. The common handling card cannot be used in the property in the alert mode, but the property in the release mode can be used for shifting to the handling mode, so that security can be ensured. Moreover, since it can be made to have arbitrary counselors, it can respond quickly.

  (3) In the above embodiment, “in-room” is determined for a specific user based on the qualification information 42 in step S12, but the user who is determined to be “in-room” is not limited to a specific user. It can also be. That is, if any user's occupancy state 40 is “occupied”, the coping PW may be switched to the coping mode. In this case, for example, two or more users such as two or more predetermined users may be present in the room.

  (4) In the above embodiment, the configuration in which the specific user is determined based on the qualification information 42 stored in advance in the storage unit 20 has been described. On the other hand, the specific user may be specified under other conditions. For example, the user who requested the coping work (handling request) to the monitoring center 8 can be a specific user, and the presence of the person can be made a condition in step S12.

  In this case, the security device 4 acquires the request information generated in response to the handling request and stores it in the storage unit 20. The request information includes the user ID of the countermeasure requester, and the user ID is specified from, for example, a user card read at the time of the countermeasure request operation via the security device 4. Further, in response requests made by the user to the monitoring center 8 by telephone or the like, the monitoring center 8 confirms the identity of the user, specifies the user ID of the user, and sends it to the security device 4 as request information. The data is transmitted and stored in the storage unit 20.

  (5) In the above-described embodiment, the occupancy state 40 is acquired and updated based on the result of reading the user card by the reader unit 14 when the user enters and leaves or moves to the area. Acquisition / update of the occupancy state 40 may be performed in other forms.

  For example, attendance and attendance registration information can be used to acquire / update the occupancy status 40. That is, each user performs attendance registration and attendance registration at the time of attendance and leaving work, and the security device 4 acquires this registration information and switches the user's occupancy status 40 to “in-room” according to the attendance registration, Switch to “absence” according to the leave registration. Further, when the user has an outing registration function when going out, the user switches to “absent” according to the outing registration, and switches to “in-room” according to the return registration when returning to the office. For example, a computer system or the like provided separately from the security device 4 is used to input the attendance / attendance registration information by the user, and the system and the security device 4 are connected to be communicable to be in the room in conjunction with the attendance / attendance registration information. It can be set as the structure which acquires the state 40. FIG. Note that the operation for attendance and attendance registration may be performed using the reader unit 14 of the security system 2 or the like.

  The other example which acquires the information regarding a user's occupancy state from the system and apparatus outside the security system 2 is shown. One of them obtains login information of a user to a personal computer connected to the intranet, and sets the occupancy state 40 to “in-room” for the logged-in user. The other one determines the presence / absence of the user from the power consumption in the monitored building or room. When the amount of power used per unit time is equal to or greater than a predetermined value or when the amount of fluctuation in power consumption is equal to or greater than a predetermined value, the user is recognized as being in the room.

  Moreover, the detection information of the sensor 10 with which the security apparatus 4 is provided can also be utilized for acquisition of the occupancy state 40. For example, if a state in which no detection signal is issued in all the monitoring sensors has continued for the past 15 minutes, the building to be monitored is determined to be unattended, and the user recognizes the absence. On the other hand, if any sensor reports, it switches from absence to occupancy. In this case, the mode management unit 52 determines whether or not the monitoring target itself is “manned” instead of “occupied” / “absent” of the specific user as the presence / absence determination of the user in the monitoring target area (S12). It is determined whether or not the handling PW can be used. It should be noted that occupant monitoring may be executed by some monitoring sensors, such as limiting to space sensors in a building.

  The user card of the above embodiment uses an RFID (radio frequency identifier) that performs short-distance communication, and reads the information by tampering with the reader unit 14, but if an RFID that performs longer-distance communication is used, the reader unit It is possible to detect the presence / absence state 40 by detecting the presence / absence of a user in a building without detecting 14 or by installing the reader unit 14 in various places to detect an area where the user exists. Become.
