The surveillance controller does not cancel the abnormality determination in the predetermined time zone, particularly the surveillance controller quickly and reliably detects the occurrence of the abnormality, while disabling abnormality canceling and suppressing a false report, since the possibility of false report by the user is low and the possibility of intrusion by a thief is high when hitting the time zone when admission itself is restricted.

Description

  The present invention relates to a security device that detects an unauthorized entry into a monitored building and determines an abnormality.

  In recent years, security devices that monitor unauthorized intrusion into monitored buildings such as office buildings, condominiums, and detached houses, and notify abnormality to a remote monitoring center via a communication line when an abnormality occurs have become widespread. As a means for detecting unauthorized intrusion, various sensors such as an open / close detection sensor for detecting the opening / closing of a door / window at a building entrance and a space sensor for detecting a human body existing in the building are used. The security device generally has a security mode for performing intrusion monitoring and a release mode for not performing intrusion monitoring as the security mode. The release mode is set while a regular user enters the building and stays in the building, and the warning mode is set while all the users leave the building and the building is unattended. For example, when monitoring an office, the working hours when an employee is in a building are set to release mode, and the night mode from when the last employee leaves the company until the next employee leaves the company is set to watch mode. Is set. Note that the security mode switching setting is performed by inputting an IC card or a personal identification number possessed by a legitimate user.

  In the case of the security device as described above, even if a legitimate user accidentally enters during the security mode, it cannot be distinguished from an intrusion by a suspicious person, so that it is determined as an intrusion abnormality. Therefore, the conventional security device waits for a report cancel operation by a regular user for a certain period of time after the sensor detects an intrusion, and reports an abnormality when the cancel operation is not performed within a certain period of time. The occurrence of false alarms by regular users is suppressed (Patent Document 1).

JP 2002-352364 A

However, if the cancel operation is allowed without limitation, the security may be deteriorated. For example, when the probability of regular users entering the building is low, such as late at night, an intrusion abnormality reporting delay may occur more than necessary, or a suspicious person may be given a grace period to perform an illegal cancellation operation.
Then, an object of this invention is to provide the security device which can suppress the misinformation resulting from the act of a regular user appropriately.

In order to achieve the above object, the security device of the present invention is a security device that monitors unauthorized intrusion into a monitored building, and a sensor unit that detects and reports an intrusion action into the monitored building;
An operation unit for inputting a cancel operation, an abnormality determination according to the notification of the sensor unit, a monitoring control unit for canceling the abnormality determination when the cancel operation is input, and a predetermined preset And a storage unit for storing the time zone, wherein the monitoring control unit does not cancel the abnormality determination in the predetermined time zone.

  According to such a configuration, it is possible to normally recognize the intruding action by the suspicious person by making it possible to cancel the abnormality determination so as to prevent the false alarm and making the cancellation impossible in a predetermined time zone. That is, it is possible to provide a security device that can suppress misreporting caused by the actions of authorized users and that is highly safe.

  As the predetermined time zone, a time zone in which there is a low possibility of occurrence of false alarms due to the action of the authorized user to be monitored is set. For example, it is usually unlikely that a user will use a building at midnight hours when there are usually no employees in the office, or during daytime hours when the house is usually unattended for work or attending school. Refers to the time limit. The security device preferably reports an entry abnormality from the security device to a remote monitoring center when a legitimate entry action is made during the admission limit time period. Alternatively, it may be determined that the entrance is abnormal at the monitoring center that has received a notification that there has been a legitimate entry from the security device (for example, a release mode setting notification).

Further, in the above configuration, the monitoring control unit has at least a security mode that performs intrusion monitoring and a release mode that does not perform intrusion monitoring as the security mode, and the sensor unit issues a warning during the security mode, and the cancellation Abnormality is determined when no operation is input and a predetermined delay time has elapsed, and the abnormality is determined without waiting for the delay time in the predetermined time zone.
According to such a configuration, it is possible to quickly and surely determine an abnormality in a predetermined time period in which the possibility of being a suspicious person is high while giving a grace period for canceling the abnormal user for a predetermined delay time.

In the above configuration, the operation unit is a unit for setting and operating the security mode, and the monitoring control unit performs the canceling operation for setting the release mode performed during the measurement of the delay time. Recognize as
According to such a configuration, if the authorized user forgets to perform the release mode setting operation and accidentally reports the sensor unit, the cancellation can be canceled by performing the release mode setting operation again within the delay time. it can.

In the above configuration, the sensor unit includes a plurality of sensors including an entrance sensor that monitors the entrance of the building and other intrusion sensors, and the operation unit is provided outside the entrance of the building, The monitoring control unit determines the abnormality without waiting for the delay time regardless of the predetermined time zone when the other intrusion sensor reports, and the predetermined time zone when the entrance sensor reports. Otherwise, the cancel operation is determined to be abnormal after waiting for the delay time, and the predetermined time zone is determined to be abnormal without waiting for the delay time.
According to such a configuration, it is possible to quickly and surely determine an abnormality by identifying an intrusion act that is not a normal admission act by allowing only a report to be canceled along with an admission act of a regular user.

  According to the present invention, it is possible to provide a security device that can suppress misreporting due to an act of a legitimate user and has high safety by making it impossible to cancel an abnormality in a preset time zone in which the possibility of misreporting is low. be able to.

It is a functional block diagram which shows schematic structure of the security apparatus in this embodiment. It is a figure which shows the example of installation of the security apparatus to the building of the monitoring object. It is a flowchart which shows operation | movement of the security apparatus in alert mode.

  Hereinafter, an embodiment relating to a security system to which the security device of the present invention is applied will be specifically described with reference to the drawings.

The security system according to the present embodiment includes a security device installed in a building to be monitored and a monitoring center connected to the security device via a communication network.
The security device is installed for each building to be monitored, and monitors the invading action of the bandits into the building using a predetermined range including the inside of the building or the outside of the building as a monitoring area. When an intrusion abnormality is detected, an abnormality report is sent to the monitoring center. As the security mode, a security mode that performs intrusion monitoring and a release mode that does not perform intrusion monitoring can be set, and the security mode is switched based on an authentication operation by an authorized user allowed to enter the building. Then, the monitoring center is notified that the security mode has been switched.

  The monitoring center manages and manages a plurality of security devices. When an abnormality report is received from the security device, the controller makes a request for countermeasures to a security guard or police agency that stands by in the vicinity of the monitored building. Further, when the monitoring center receives a notification that the release mode is set from the security device during the entrance time limit preset for each security device, the monitoring center determines that the entrance is abnormal. If an admission abnormality is detected, the controller will check the reason for admission by telephone. If you cannot confirm that you are a legitimate user, or if you cannot confirm a valid reason, make an emergency call to the manager of the building, or make a request for countermeasures to a guard or police organization.

  Here, even a legitimate user may cause an intrusion abnormality due to erroneous entry during the alert mode. In order to prevent such a false report from an authorized user from being reported to the monitoring center, the security device has an operation means for canceling the detection of the intrusion abnormality. The user can cancel the report of the intrusion abnormality by authenticating that the user is an authorized user using the operation means. However, it is assumed that the cancel function is invalidated during a time period when a normal user is unlikely to use a building, and an intrusion abnormality is promptly and reliably performed to the monitoring center.

Hereinafter, the configuration and operation of the security device will be described in detail.
FIG. 1 is a functional block diagram showing a schematic configuration of the security device. Moreover, FIG. 2 is a figure which shows the example of installation of the security apparatus to the building of the monitoring object.
The security device 1 includes an intrusion sensor 10, a card reader 20, and a control terminal 30. The control terminal 30 includes a sensor I / F 32, a notification unit 34, a reader I / F 36, a clock unit 38, a notification unit 40, a storage unit 42, and a monitoring control unit 44.

  A plurality of intrusion sensors 10 are installed everywhere in the building that is the monitoring area, and detects an intrusion action into the monitoring area. When an intrusion is detected, a detection signal with its own identification code is output to the control terminal 30. As the intrusion sensor 10, for example, a space sensor that generates an alarm by detecting infrared rays emitted from a human body, an infrared sensor that generates an alarm by detecting a blockage of infrared rays between light projecting and receiving units, and a door being opened. An open / close detection sensor or the like is used to detect and report. The intrusion sensor 10 is roughly classified into an entrance sensor 10q that monitors the entrance of a building and other general intrusion sensors 10p.

  In the installation example of FIG. 2, intrusion sensors 10-1 to 10-4 that detect opening and closing of windows are provided on windows that can be an intrusion route into a building. In addition, an intrusion sensor 10-5 that detects opening and closing of the door is provided at the entrance of the building. Furthermore, intrusion sensors 10-6 to 10-8 that detect a human body existing in each room are provided inside the building. Among these intrusion sensors 10-1 to 10-8, an intrusion sensor 10-5 that monitors an entrance door that is a normal entrance route corresponds to the entrance sensor 10q, and the other intrusion sensors 10-1 to 10-4. And 10-6 to 10-8 correspond to the intrusion sensor 10p. An intrusion sensor 10-6 that monitors the vicinity of the entrance may be included in the entrance sensor 10q.

  The card reader 20 is an input means for authenticating that the user is an authorized user, and is installed near the entrance outside the building as shown in FIG. The card reader 20 communicates with an IC card lent to an authorized user in advance without contact, and acquires a card-specific identification code stored in the IC card. The card reader 20 transmits an inquiry signal having a predetermined frequency to the vicinity of the front surface, and receives a response signal of an IC card existing in this range. Then, the identification code of the IC card included in the response signal is extracted.

  The card reader 20 is provided with an operation button for selecting a security mode. When the card reader 20 reads the IC card after the warning mode setting button is operated, the card reader 20 sends the acquired identification code of the IC card and a setting request signal to the warning mode to the control terminal 30. When the IC card is read after the release mode setting button is operated, an identification code and a release mode setting request signal are sent to the control terminal 30. It is also possible to omit the release mode setting button and send the identification code and the release mode setting request signal to the control terminal 30 simply by reading the IC card. The card reader 20 is provided with a display means such as an LED, and displays the authentication result received from the control terminal 30 and the current security mode. The card reader 20 functions as a setting unit for setting and operating a security mode and an operation unit for inputting a cancel operation in the present invention.

  The control terminal 30 is connected to each intrusion sensor 10 and the card reader 20, and performs monitoring processing such as setting of a security mode and abnormality determination based on signals input from the respective intrusion sensors 10 and the card reader 20. As shown in FIG. 2, the control terminal 30 is installed in a building to be monitored.

The sensor I / F 32 functions as an interface that receives the detection signal output from each intrusion sensor 10 and passes the signal to the monitoring control unit 44.
The notification unit 34 is a means for notifying the surroundings of the occurrence of an abnormality, and is configured by a speaker, a lamp, or the like.
The reader I / F 36 functions as an interface for communicating between the monitoring control unit 44 and the card reader 20.
The clock unit 38 is a means for measuring the current time.
The reporting unit 40 is a communication adapter such as a modem that performs communication with the monitoring center via the communication network.

  The storage unit 42 stores various programs for operating the control terminal 30, and stores the registration identification code, the currently set security mode, the admission limit time zone, and sensor information in an updatable manner. The registered identification code is an identification code given to an IC card possessed by a legitimate user. The entrance restriction time zone is usually a time zone in which a regular user does not plan to use the building. For example, “00:00 to 05:00”, which is a midnight time zone, is set. Further, the sensor information is an identification code unique to each intrusion sensor 10 and makes it possible to distinguish whether each intrusion sensor 10 is an entrance sensor 10q or another intrusion sensor 10p.

The monitoring control unit 44 controls each unit and executes monitoring processing.
The monitoring control unit 44 sets a security mode according to a user operation via the card reader 20 and registers the current security mode in the storage unit 42. In the present embodiment, the security mode includes a security mode and a release mode. The security mode is a security mode in which when a user is in an unattended state that is not in a building in the monitoring area, an intrusion action to the building is monitored and an abnormality is reported. For example, when an office building is targeted for monitoring, it is set by the employee who leaves the office last, and is used at night and on holidays when the employee does not exist in the building. The release mode is a security mode in which intrusion monitoring is not performed so that the user can freely move in and out of the monitoring area in and out of the building when the user is in a manned state in the monitoring area. For example, when an office building is to be monitored, it is used during normal working hours when employees enter or leave the building.

  When the monitoring control unit 44 receives the setting request signal for the warning mode from the card reader 20, the monitoring control unit 44 checks the ID code of the sent IC card with the registered identification code registered in advance in the storage unit 42. If so, the security mode is switched to the warning mode. Then, the authentication result and the fact that the warning mode is set are returned to the card reader 20. If it is already in the alert mode, the setting request is ignored. Similarly, when a setting request signal for the release mode is received from the card reader 20, the setting is switched to the release mode after collating with the registered identification code. In addition, when the security mode is switched, the monitoring control unit 44 notifies the monitoring center via the reporting unit 40. When the release mode is set, a release setting notification is performed, and when the warning mode is set, a warning setting notification is performed.

  The monitoring control unit 44 performs an abnormality determination process based on the detection signal from the intrusion sensor 10 and the setting request signal from the card reader 20, the current security mode registered in the storage unit 42, sensor information, and the admission limit time zone. Execute. When it is determined that the intrusion has occurred by the bandit, the intrusion abnormality is reported to the monitoring center.

The monitoring process in the monitoring control unit 44 will be described with reference to FIG.
FIG. 3 is a flowchart showing the operation of the security device 1 during the security mode.
When the alert mode is set in response to the setting request from the card reader 20, the monitor controller 44 executes the following monitoring process. The monitoring control unit 44 monitors the input of the setting request signal to the release mode from the card reader 20 and the detection signal from the intrusion sensor while being set in the alert mode (S102 to S104). When a release mode setting request signal based on the operation of the authorized user is received (Yes in S102), the security mode is switched to the release mode (S106), and the monitoring center is notified that the release mode has been set. (S108). When the monitoring center receives the notification of switching to the release mode, the monitoring center determines whether or not the entrance is abnormal based on whether or not the current time is within a preset entrance time limit.

  When a detection signal is received from the intrusion sensor 10 (Yes in S104), the received intrusion sensor 10 is collated with the sensor information in the storage unit 42, and the intrusion sensor 10 that has been notified is the entrance sensor 10q. It is determined whether or not (S110). If it is not the entrance sensor 10q but another intrusion sensor 10p (No in S110), that is, if an intrusion from a window or the like different from the user's entrance route or a human body is detected in the building, it is determined that the intrusion abnormality is caused by a bandit. Then, the intrusion abnormality is immediately confirmed (S118). Then, the notification unit 34 is activated to display an alarm, and an intrusion abnormality report is sent to the monitoring center (S120).

When the reported sensor is the entrance sensor 10q (Yes in S110), it is subsequently determined whether or not the current time is within the admission limit time zone (S112).
If it is not in the admission limit time zone (No in S112), the intrusion abnormality is not confirmed immediately, and the intrusion abnormality is made after waiting for the canceling operation by the user for a predetermined time in order to remedy the misinformation due to the forgotten operation by the authorized user. To confirm. In other words, there is a possibility that a legitimate user has forgotten to set the release mode without noticing that it is in the alert mode. Only for a predetermined time, the abnormality can be canceled. Specifically, it is monitored whether or not the setting operation of the release mode by the authorized user is performed by the card reader 20 between the detection by the entrance sensor 10q and the elapse of a predetermined delay time ( S114 to S116).

  When the cancel mode setting request signal is received from the card reader 20 within the delay time and it is determined that the request is from a legitimate user (Yes in S114), the security mode is shifted to the cancel mode (S106), and monitoring is performed. The center is notified of switching to the release mode (S108). If the delay time has passed without the release mode setting operation being performed (Yes in S116), it is determined that the intrusion has occurred due to the bandit (S118), and the intrusion abnormality is confirmed (S118), and the intrusion abnormality notification is sent to the monitoring center ( S120).

  On the other hand, even if the entrance sensor 10q is informed, if it is in the entrance restriction time zone (Yes in S112), it is a time zone in which the authorized user does not use the building in the first place. Hard to think. Therefore, the monitoring control unit 44 invalidates the cancel operation at the time corresponding to the entrance restriction time zone. Specifically, without waiting for the delay time for the setting operation to the release mode, the intrusion abnormality is immediately determined (S118), and the intrusion abnormality notification is performed (S120). In other words, even if the release mode setting operation is performed after the entrance sensor 10q issues a warning, the abnormality is not canceled.

  As described above, according to the security device of the present embodiment, it is possible to remedy an erroneous report caused by a normal user forgetting to set the release mode and opening the entrance door, etc. by a cancel operation, while an erroneous report by an authorized user. In the admission restriction time zone where there is a low possibility of emergency, the cancel operation is invalidated and the intrusion abnormality is immediately confirmed to make an emergency call promptly and reliably. Thereby, it is possible to realize a security service that combines convenience and safety.

  In the above embodiment, the cancel mode setting operation within the delay time is also used as the cancel operation for the abnormality. However, the cancel operation for cancel operation is provided on the card reader, and the cancel operation is performed separately from the cancel mode setting operation. It can also be configured to perform. In this case, the user who has accidentally reported the entrance sensor once performs a cancel operation using the cancel button and the IC card with a card reader, and then enters the release mode setting operation again.

  In addition, the IC card is used to authenticate the user when the security mode is set or canceled, but biometric authentication such as fingerprints or authentication using a personal identification number may be used instead of the IC card. Good. In this case, an operation device that accepts reading of biometric information or input of a personal identification number may be used instead of the card reader.

  Further, in the above embodiment, an explanation has been given of an example of abnormal cancellation when the entry sensor is forgotten for the cancellation mode setting operation, but the present invention is not limited to this example, and is within the scope of the present invention. It can be applied to various scenes. For example, it is possible to use a configuration in which the notification of all sensors can be canceled for a certain period of time using a portable canceling operator or the like, and the canceling operation is invalidated only in a predetermined time zone set in advance. This configuration is a case where intrusion monitoring is performed using only intrusion sensors on the outer periphery of the building (windows, doors, etc.) while a user is present in a building such as a dwelling unit. It can be applied to a use in which a time period in which only a user stays or a time period in which a user is not active, such as midnight, is canceled and priority is given to a quick abnormality report.

  Further, in the above embodiment, the configuration in which the monitoring center determines whether or not an abnormal entry of the authorized user during the entrance restriction time period is exemplified, but the security device performs this determination and notifies the monitoring center of the occurrence of the entrance abnormality. Also good. In this case, when it is determined in S <b> 102 that there is a release operation in the operation flowchart illustrated in FIG. 3, the security device subsequently determines whether or not the current time is within the admission limit time zone. If it is not in the admission time limit, release mode setting and switching notification will be performed as usual. On the other hand, when it falls within the immigration limit time zone, the mode is set to the release mode and the monitoring center is notified that an entrance abnormality has occurred.

  Moreover, although the said embodiment demonstrated the structure which waits for delay time for cancellation operation when an intrusion sensor alert | reports, abnormality is fixed, It is not limited to this. For example, a configuration may be adopted in which, after an abnormality is confirmed / abnormally reported in response to a notification from the intrusion sensor, the confirmed abnormality is canceled and a cancellation notification is issued when a cancel operation is performed within a predetermined time.
