Description

  The present invention provides a security mode for a monitoring target, a warning mode set when there is no user in the monitored area, a release mode set when there is a user in the area, and the monitoring target. The present invention relates to a security system capable of switching a coping mode used by coping personnel dispatched to the coping operation.

  In the security system, in addition to a warning mode and a release mode, a response mode that is set during response operations, such as a patrol mode for security personnel to check for abnormalities, and a maintenance mode for security personnel and maintenance workers to perform periodic inspections, 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. .

  The security system detects an abnormal state by executing intrusion monitoring or the like during the warning mode. On the other hand, some abnormality monitoring is executed even in the release mode, and it may be necessary to deal with the detected abnormality even in the release mode.

  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.

  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 memorize | stores the time slot | zone (guard scheduled time slot | zone 40) by which the setting of alert mode is scheduled. In the scheduled security time zone 40, a time zone that should normally be set in the security mode is registered in advance. For example, a time period from when all employees leave work, such as from 23:00 to 5:00, until the first work is registered. Further, only the scheduled security start time may be registered as the scheduled security time zone 40.

  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, 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. Further, if the user does not set the alert mode even if the current time is in the scheduled security time zone, that is, if the release mode is maintained, the abnormality monitoring processing unit 50 determines that the situation is an unset abnormality (non-monitoring abnormality). judge. 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.

  Here, a more detailed operation of the abnormality monitoring processing unit 50 regarding an unset abnormality will be described. The abnormality monitoring processing unit 50 displays, for example, a guidance that informs the arrival of the scheduled start time of the guard when it is in the release mode when the scheduled start time of the security (or a time that precedes for a predetermined time such as 15 minutes before) has arrived. To do. In response to the guidance, the user can perform an extension operation to change the scheduled security start time. When extended, the abnormality monitoring processing unit 50 operates according to the changed scheduled time. If the security start scheduled time (or a time after a predetermined time such as 15 minutes elapses) has arrived, the abnormality monitoring processing unit 50 determines that the abnormality has not been set, and proceeds to the monitoring center 8. Notifying the unset abnormality and storing an unset abnormality state by setting an unset abnormality flag in the storage unit 20 or the like. Note that when the monitoring center 8 also performs monitoring based on the security mode transmitted from the security device 4, the notification of the unset abnormality from the security device 4 can be omitted. The abnormality monitoring processing unit 50 holds the determination that there is an unset abnormality until the state is shifted to the alert mode, the extension operation is performed, or the recovery operation is performed by the coping staff and the recovery signal is input.

  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 monitoring including an intrusion abnormality by the sensor 10 is performed, which is selected and set in a state where the user leaves the area to be monitored and becomes unattended. 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 that is selected and set in a state where a user can exist in the monitoring target area and the monitoring of the intrusion abnormality is released, and the sensor 10 is stopped or the intrusion detection signal is invalidated. . By the way, even in the release mode, if a detection signal such as an emergency operation signal, device abnormality, or unset abnormality is issued, the monitoring center 8 is notified, and a security guard is dispatched to the reporting source property.

  The coping mode is used by a person (coordinator) 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.

  Here, since the security system 2 performs intrusion monitoring during the security mode, the user who finally leaves the monitored property needs to switch from the release mode to the security mode using the user card. If this mode switching operation is forgotten, it will be left unattended in an unmonitored state. Therefore, when the security start scheduled time stored in the storage unit 20 has passed, the abnormality monitoring processing unit 50 detects that the abnormality has not been set when the release mode is left. When an unset abnormality is detected, for example, the controller of the monitoring center 8 confirms the user by telephone, and dispatches a coping person if the confirmation cannot be obtained or is suspicious. The coordinator sets the property to be monitored to the coping mode, checks the presence / absence of occupants, checks for abnormalities during the non-monitoring period (safety confirmation), etc., and if there is no problem, sets the alert mode to finish the coping.

  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 that includes 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 method to notify a counselor who is close to a monitored property or a counselor who is not available, you can quickly start dealing with the property and reduce the waiting time for the user of the property. 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 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. In particular, the storage unit 66 stores the current security mode sent from the security device 4 for each property to be monitored and whether or not the security device 4 has detected an abnormal state.

  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 an unset abnormality is detected (in the case of “Yes” in step S12), the input countermeasure PW is collated with the temporary PW stored in the storage unit 20 (determination PW36). 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 (in the case of “No” in step S10), when the unset abnormality is not detected (in the case of “No” in step S12), and If the input countermeasure PW does not match the temporary PW stored in the storage unit 20 (in the case of “No” in step S14), the mode management unit 52 determines that the transition to the security mode has failed and sets the current mode. Maintain (step S18). 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 coping PW input operation itself may be rejected in the alert mode or in the non-detection state of the unset abnormality. For example, in the release mode and the unset abnormal state, the operation menu displayed on the touch panel display of the operation display unit 12 has an option for accepting the input of the countermeasure PW, whereas the warning mode and the unset abnormal state are not detected. Then, it can be set as the structure which does not display the said choice.

  Since the security mode is basically the release mode while an unset abnormality is detected, the determination in step S10 can be omitted.

  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. If the counselor possesses a security card with higher security than the coping PW, not only the release mode where the user is basically located in the property but also that the user is basically absent in the property. Switching to the coping mode is permitted even in a possible alert mode. Thereby, the coping person can perform various coping operations including intrusion abnormality.

  Here, since the user is basically in the property in the release mode, the user's intention can be confirmed in the coping operation, and in some cases, the coping operation can be requested for cooperation. Specifically, when an unset abnormality is detected, for example, the supervisor of the monitoring center confirms the user by telephone, and if it can be confirmed, requesting the set of the warning mode when leaving, it is currently handled Can be judged as unnecessary. On the other hand, if the confirmation cannot be obtained or if it is suspicious, a coping staff is dispatched. The dispatched counselor sets the monitored property to the coping mode and performs the above-described safety check. At this time, as described above, the security system 2 can quickly cope with an unset abnormality by enabling the switching from the release mode to the handling mode by the handling PW without the handling card. In addition, by allowing switching to the handling mode in the handling PW only when an unset abnormality is detected in the release mode, security in the normal state in the release mode or in the alert mode It can be secured.

  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). 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). Then, when the countermeasure PW matches (in the case of “Yes” in step S42), the mode management unit 52 sets the security device 4 to the release mode or the warning mode in response to a request from the countermeasure in the operation display unit 12 (S34). Transition is made (steps S36, S38). In the handling work for an unset error, the coping person sets a warning mode and ends the handling. Note that the coping PW may be switched to only the alert mode, and a user card may be required to switch to the release mode.

  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.

  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 the security mode can be switched by the countermeasure PW regardless of whether the countermeasure mode of the current mode is set by either the countermeasure card or the countermeasure PW.

  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. 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. .

[Second Embodiment]
In the following description of 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 the present embodiment, when the control unit 68 of the monitoring center 8 dispatches a coping person who does not have a coping card to the coping process of the property, the coping work with the coping PW is performed on the security device 4 that is the coping destination. A countermeasure command is transmitted as countermeasure approval information indicating that the monitoring center 8 has approved.

  The security device 4 stores the received countermeasure command in the storage unit 20. The security device 4 deletes the response command from the storage unit 20 when the recovery operation by the response member is completed. Further, when it is detected that the monitoring center 8 has changed from the release mode to the warning mode based on the security mode received from the security device 4, a command for canceling the countermeasure command may be transmitted to the security device 4. The cancellation command may be transmitted in response to an operation by the controller, or may be automatically performed by the control unit 68.

  The mode management unit 52 of the security system 2b switches to the response mode by the response PW on the condition that the security mode is the release mode, an unset abnormality is detected, and the response command is stored. It differs from the first embodiment in that it is allowed. Referring to the flowchart of FIG. 2, in the first embodiment, the mode management unit 52 switches from the release mode to the handling mode when the handling PW is input (in the case of “Yes” in S6). When determining whether or not switching is possible (in the case of “Yes” in S10), in addition to authentication by the handling PW (S14), it is a condition that an unset abnormality is detected (in the case of “Yes” in S12) However, in this embodiment, in addition to the detection of an unset abnormality, an additional condition is 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).

  Further, the processing at the time of operation by the user card and the countermeasure 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 countermeasure mode is 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 S12 shown in FIG. 2, the mode management unit 52 collates the input countermeasure PW and the temporary PW received from the monitoring center 8 by the security device 4, and allows a 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 differences between the security system 2c of the third embodiment and the first embodiment will be mainly described.

  The schematic configuration of the security system 2c is the same as that shown in FIG. 1 for the security system 2 of the first embodiment. However, the mode management unit 52 of the security system 2c allows the switching to the countermeasure mode by the countermeasure PW on condition that an abnormality is detected by the abnormality monitoring even if the guard mode is the alarm mode. This is different from the first embodiment.

  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. In the first embodiment, the mode management unit 52, when the countermeasure PW is input (in the case of “Yes” in S6), when the security mode is the alert mode (in the case of “No” in S10). However, in this embodiment, when the security mode is the warning mode (in the case of “No” in S10), the abnormality monitoring processing unit 50 detects an abnormality. If “Yes” in S50, the transition to the handling mode is permitted by authentication by the handling PW (in the case of “Yes” in S14). On the other hand, when no abnormality is detected in the warning mode (in the case of “No” in S50), and when abnormality is detected in the warning mode, the input coping PW is equal to the temporary PW in the storage unit 20. If not (No at S14), no mode transition is performed (step S18).

  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. 2, and the processing in the countermeasure mode is in the first embodiment described with reference to FIG. It is the same as the process.

  The features of this embodiment can also be applied to the security systems 2b and 2c of the second and third embodiments.

[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 first embodiment will be mainly described.

  The security system 2d 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. 5 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. 5, the same steps as those in FIG. 2 are denoted by 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.

  Further, 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 coping 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.

  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 the present 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 when the user is in a release mode, and there is no user response. Since entrance is restricted, user requests can be handled quickly and security can be ensured.

  The features of this embodiment can also be applied to the security systems 2b and 2c of the second and third embodiments.

[Fifth Embodiment]
Hereinafter, regarding the security system 2e according to the fifth 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 of the security system 2e of the fifth embodiment from the above embodiment will be mainly described.

  The general configuration of the security system 2e 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 the present embodiment and the second embodiment is that the control unit 68 of the monitoring center 8 deals only when the security device 4 to be dealt with is in the release mode and an unset abnormality is detected. The point is to issue a command.

  Specifically, 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 of the security device 4 stored in the storage unit 66 and the detected abnormal state, and the security device 4 to be dealt with is set to the release mode, Furthermore, when an unset abnormality is detected, issue of a countermeasure command is permitted. On the other hand, if no unset abnormality is detected even in the release mode, or if the alert mode is set, 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 an unset abnormality is detected. In the process of switching to the countermeasure mode by the countermeasure PW in FIG. 2, the determination whether or not the mode is the release mode (S10) and the determination of whether or not an unset abnormality has been detected (S12) It is replaced with the determination of whether or not it is stored. 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).

[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 may 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) When an unset abnormality occurs, the monitoring center 8 may contact the user for confirmation, so that the user may perform an extension operation or a warning mode setting. In this case, dispatch of coping personnel and coping operations are not required. Therefore, the mode management unit 52 may accept the handling PW for the first time after a predetermined delay time (for example, 20 minutes) has elapsed after the abnormality monitoring processing unit 50 determines that the unset abnormality has occurred.

  (4) Although the abnormality monitoring processing unit 50 of the security device 4 monitors the occurrence of an unset abnormality in the above embodiment, the monitoring may be performed by the monitoring center 8. Specifically, a security scheduled time zone is registered for each property in the monitoring center 8, and a security device that has not received a mode transition signal for notifying the setting of the security mode even when the time has arrived is not set. The abnormality is determined and displayed, and the security device 4 is notified of the unset abnormality. In addition, you may perform the monitoring of an unset abnormality separately in both the monitoring center 8 and the security apparatus 4. FIG.

  (5) It is good also as a condition that the occupant is not detected by the occupant check when the scheduled security start time arrives or after the scheduled time. For example, the security device 4 recognizes that there is no occupant if a state in which a human body is not detected by a space sensor or the like continues.

  (6) In the above embodiment, a configuration has been described in which switching to the countermeasure mode is permitted by the countermeasure PW due to an unset abnormality. Here, in place of an unset abnormality, a configuration in which switching to the countermeasure mode is permitted by the countermeasure PW in another abnormal state in the release mode of the security device 4 to enable quick countermeasures to these abnormal states. You can also. Examples of the abnormal state include emergency abnormalities, emergency abnormalities, fire abnormalities, and other equipment abnormalities and equipment abnormalities that are considered difficult for the user to respond and confirm.
