Description

  The present invention relates to a security device, a security method, and a security program. In particular, the present invention relates to a security device, a security method, and a security program that reduce false alarms.

  In security devices used for security of buildings such as buildings and houses, when sensors installed at entrances and passages of buildings detect abnormalities such as intruders, the abnormality is reported to the security center connected to the security device and the network. To do.

  However, if the user switches the operation mode of the security device from the security release mode to the security mode and at the same time the detection of abnormality by the sensor and the notification to the security center are enabled, the user switches the operation mode and then from the building Until the user leaves the building, the user is detected by the sensor, and an abnormality is reported to the security center. In addition, when a user enters a building where the security device is in the security mode, the user is detected by the sensor at the stage before the security device is switched from the security mode to the security release mode. Abnormality is reported. As a result, the security staff at the security center will be dispatched to the site in order to confirm the abnormality despite the false alarm.

  Therefore, normally, even if the sensor detects an abnormality for a predetermined time after the operation mode is switched from the security release mode to the security mode for a predetermined time and when the operation mode is in the security mode, the sensor detects the abnormality for a predetermined time. A grace time is set in the security device so that the security center is not notified.

  For example, Patent Document 1 discloses an invention in which the time required for switching the security mode is actually measured using a plurality of sensors, and the measured actual time is used as the timer time in the entrance timer function and the exit timer function. Has been.

  However, in the invention according to Patent Document 1, in the state where the timer time is set in advance using the actual measurement time measured without returning the exit route during the exit, for example, the user has left the store due to forgetting something. When the timer time is exceeded when returning to the inside of the building, an abnormality is reported to the security center.

  In this regard, Patent Document 2 discloses an invention in which a timer is stopped when a user has a portable terminal and the intensity of a radio wave received by the security device from the portable terminal exceeds a threshold value. .

It is a flowchart which shows the operation | movement flow of the security apparatus which concerns on embodiment of this invention.

[Concept of the Invention]
First, the concept of the present invention will be described in detail using the example shown in FIG. The example shown in FIG. 1 is a floor plan of an office in a building, and the office includes a store, an office, and a hallway. It is possible to enter and exit the office through the entrance 40-1 provided in the corridor and the entrance 40-2 provided in the store. A door 30-1 is provided between the hallway and the office, and a door 30-2 is provided between the hallway and the store. Infrared sensors 20-1 and 20-2 are provided on the ceilings of the office and the store, respectively, and can detect the presence of a person in the room. In addition, an image sensor 20-3 is provided in the hallway, and it is possible to detect the presence of a person in the hallway. It is assumed that the security device main body 10 is provided in the office. Each of the entrances 40-1 and 40-2 is provided with an electric lock, and the infrared sensors 20-1 and 20-2 provided on the ceiling of the office and the store are usually passive sensors. However, it can be replaced by providing an active sensor on the ceiling or wall of an office or store.

  Here, it is assumed that the user switches the operation mode of the security device from the security release mode to the security mode by operating the switching unit of the security device main body 10. In addition, the exit timer starts counting from the time of mode switching, and in the initial state, it times out in 5 seconds.

  In the example shown in FIG. 1, in addition to the above-described 5-second exit timer time, 5 seconds is extended each time each sensor detects the presence of a user.

  Specifically, when the user exits the route “Exit Route A” shown in FIG. 1, the exit timer is switched by switching the operation mode of the security device to the security mode using the switching unit of the security device body 10. First, since the infrared sensor 20-1 provided on the ceiling of the office detects the presence of the user, 5 seconds is added to the timer time. Next, when the user moves from the office to the corridor through the door 30-1, the image sensor 20-3 provided in the corridor detects the presence of the user, so another 5 seconds is added to the timer time. The As a result, when the user exits the “Exit Route A” route, the timer time is 15 seconds in total. If the exit is completed within 15 seconds, the security device will not notify the Security Center of an abnormality. Absent. (In this case, the operation mode in a period in which the abnormality is not notified to the security center even if the sensor detects an abnormality while in the security mode is also referred to as a “temporary security mode”.)

  On the other hand, “Exit Route B” shown in FIG. 1 is a route when the user notices something forgotten in the middle of leaving, enters the store, and then leaves. Similar to the case of exiting from the “Exit Route A” route, the operation of the security device is switched to the security mode using the switching unit of the security device main body 10 to start the exit timer first. Since the infrared sensor 20-1 provided on the ceiling of the office detects the presence of the user, 5 seconds is added to the timer time. Next, when the user moves from the office to the corridor through the door 30-1, the image sensor 20-3 provided in the corridor detects the presence of the user, so another 5 seconds is added to the timer time. The Thereafter, when the user notices a forgotten thing and enters the store, the infrared sensor 20-2 provided on the ceiling of the store detects the presence of the user, and therefore, 5 seconds is further added to the timer time. After that, when the user goes out again through the door 30-2, the image sensor 20-3 provided in the corridor detects the presence of the user again, so that another 5 seconds is added to the timer time. The As a result, when the user exits the “Exit Route B” route, the timer time is 25 seconds in total. If the exit is completed within 25 seconds, the security device will not notify the Security Center of an abnormality. Absent.

  Regardless of whether the user leaves the exit route “Exit Route A” or “Exit Route B”, when the exit timer reaches 0 seconds, the operation mode of the security device is the above-mentioned “temporary security”. Instead of “mode”, when the sensor detects an abnormality, the operation mode is to report the abnormality to the security center. (This is also referred to herein as “actual security mode”.)

  The above is the concept that forms the gist of the present invention.

[First Embodiment]
Next, the configuration of the security device 100 according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 2, the security device 100 includes a control unit 110, sensors 120-1 to 120-n, an electronic lock control unit 130, a storage unit 140, a switching unit 150, a notification unit 160, a holding unit 170, and an extension unit 180. Timer 190 is included.

  The control unit 110 is a part that controls the entire security device 100 and may include a CPU that processes various signals, a ROM that stores a boot program and an application program, and a work RAM.

  The sensors 120-1 to 120-n are sensors for detecting an abnormality, and specifically, are sensors that detect the presence of a person using, for example, infrared rays or images. Here, these sensors 120-1 to 120-n may be collectively referred to as “sensor 120”.

  The electronic lock control unit 130 is a part that controls the electronic lock 300 according to the operation mode or the like of the security device 100.

  The storage unit 140 stores system data such as a report history / report destination, maintenance history, and the like, and can be realized using, for example, an EEPROM.

  The switching unit 150 is a part that switches the operation mode of the security device 100 between the security mode and the security release mode. The operation mode may be switched by a human operating the switching unit 150, but the operation mode may be automatically switched using, for example, a timer 190 described later.

  The reporting unit 160 is a part connected to the security center 250 via the network 200 shown in FIG. 2, and when any of the sensors 120-1 to 120-n detects an abnormality, the abnormality is guarded. This is the location that reports to the center 250.

  The holding unit 170 detects an abnormality with any of the sensors 120-1 to 120-n while the exit timer is counting down, that is, when the timer time is not 0 seconds, by the timer 190 described later. Even if it does, it is a part which suspends the report of the abnormality to the security center 250 by the report part 160. FIG.

  When the extension unit 180 detects an abnormality in any of the sensors 120-1 to 120-n while the exit timer is counting down by the timer 190 described later, the extension timer 180 is configured as described above. This is the place where the time corresponding to the sensor that detected the abnormality is added to the time. The addition time may be equal for each timer or may be different for each sensor.

  The timer 190 is a timer that starts a countdown from the initially set number of seconds when the operation mode of the security device 100 is switched from the security release mode to the security mode. As long as the number of seconds of this timer is not 0, the reporting unit 160 reports the abnormality to the security center 250 even if any of the sensors 120-1 to 120-n detects an abnormality as described above. The time corresponding to the sensor that detected the abnormality is added to the timer time.

  These control unit 110, sensors 120-1 to 120-n, electronic lock control unit 130, storage unit 140, switching unit 150, notification unit 160, holding unit 170, extension unit 180, and timer 190 are mutually connected via a bus. It is possible to send and receive signals.

  Next, the operation flow of the security device 100 according to the first embodiment of the present invention will be described with reference to FIG.

  First, in step S11, the switching unit 150 sets the operation mode of the security device 100 to the security mode. As described above, a human may manually operate the switching unit 150 to switch the operation mode, or the switching unit 150 may automatically switch the operation mode.

  Next, in step S12, the timer 190 is started. Specifically, the timer 190 counts down from the initial number of seconds.

  Next, in step S13, it is determined whether the sensor 120 has detected an abnormality.

  When an abnormality is detected in step S13 (S13: Yes), in step S14, the control unit 110 determines whether the timer 190 has timed out, that is, whether the countdown is completed or the count is continuing.

  If the timer 190 has not timed out in step S14, that is, if the count is being continued (S14: No), the timer 190 extends the timer time in step S15. That is, the time corresponding to the sensor 120 that detected the abnormality is added to the current timer time. Thereafter, the process returns to step S13.

  If the timer 190 has timed out in step S14, that is, if the countdown has ended (S14: Yes), the reporting unit 160 reports an abnormality to the security center 250 in step S16.

  In step S13, if the sensor has not detected an abnormality (S13: No), the timer 190 continues to count down in step S17.

  Next, in step S18, it is determined whether or not the timer 190 has timed out. When the time-out has occurred (S18: Yes), the security device 100 ends the operation in the “temporary security mode” and shifts to the operation in the “actual security mode”.

  In step S18, when the timer 190 has not timed out (S18: No), the process returns to step S13, and the operation in the “temporary security mode” is continued.

  By using the security device 100 according to the present embodiment, it is possible to reduce false alarms that occur when the user behaves differently from normal exit, and to reduce the security burden. In addition, it is preferable from the viewpoint of security that the time until the security mode is changed from being unattended is preferable from the viewpoint of security, but by using the security device 100 according to the first embodiment, the exit timer time has a margin in advance. Even if the time is not set, the necessary amount of time is added, so that security can be improved.

[Other Examples]
In the description of the above-described embodiment, the specific sensor is not specified, but some of the plurality of sensors may be image sensors. In particular, an image sensor having a face authentication function may be used, and the timer time is extended only when an image authenticated by the face authentication function can be collated with user data stored in the storage unit 140 in advance. It is good. In addition, the timer time may be extended for a longer time than when other sensors detect an abnormality, for example, the presence of a human being.

  Thereby, it is possible to extend the extension time of the timer according to the accuracy of the detected human being a normal user.

  Further, the extended time when an abnormality is detected in a sensor relatively far from the building entrance may be longer than the extended time when an abnormality is detected in a sensor relatively close to the building entrance. This corresponds to the longer time required to leave the building, the farther the user is from the building entrance.

  In the description according to the above embodiment, the electronic lock control method is not specifically described. Alternatively, the electronic lock 300 may be unlocked, and the electronic lock 300 may be locked when the “temporary security mode” is completed and the state is shifted to the “actual security mode”.

  In the above embodiment, a plurality of sensors are present. However, the present invention can be applied to a security device including only a single sensor.

  Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

  Each part of the security device can be realized by either hardware, software, or a combination thereof. Also, the security method performed by the security device described above can be realized by either hardware, software, or a combination thereof. Here, being realized by software means that the computer reads and executes a program, or that hardware realizes operation according to microcode corresponding to the program.

  The program may be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-ROMs. R, CD-R / W, semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)). The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire and an optical fiber, or a wireless communication path.
