  • the interface monitors the condition of various items related to the lock and the area around it, intelligently interpreting the conditions, reporting status to the external alarm system and providing control to external monitoring or information to display devices.
  • certain alarm and monitoring systems are triggered whenever motion is detected in or near a protected area, such as outside a safe.
  • a motion detector directly causes the alarm system to react, such as by calling the police or performing some other alarm response.
  • a motion detector could be used to cause a video tape recorder to begin recording events in the area.

  • the inventive interface intelligently interprets the conditions that are input to it, and reports status to the alarm system, and/or controls other devices or provides information to display devices.
  • the inventive interface's monitoring and intelligent interpretation reduces occurrences of false alarms, such as when an authorized individual routinely unlocks the lock after forgetting to disable the alarm system.
  • the inventive interface allows more appropriate control of other monitoring devices such as a video recorder, which can be controlled to record a video image only during certain events of interest.
  • This intelligently-controlled recording thereby minimizes the amount of storage required for the video recordings, and reduces the amount of time required for security personnel to locate an event of interest on the tape.

The opening and subsequent extension of the bolt to re-close the lock may be performed in any conventional manner, and details thereof need not be included in this discussion.
  • the lock provides a beep/LED signal on lines 106, 1 16 to the keypad.
  • This beep/LED signal causes a beeper or LED (not shown) on the keypad unit 1 10 to sound or to be illuminated, in response to a key closure, entry of an incorrect combination, low batteries, or other condition programmed into the lock ' s microcontroller.

  • data signals from the keypad unit 1 10 may be tapped from the data line passing through it, as may information from the beep/LED line from lock 100. This is in addition to the fact that the interface inputs the state of the "bolt extended” and “bolt retracted” indicators in lock 100.
  • inventive alarm interface 200 envisions that information from a variety of sources may be input, so as to monitor the condition of not only the lock system itself, but of other components as well.

  • Various other monitoring devices, and combinations thereof, are contemplated for use in conjunction with the inventive interface 200.
  • the door sensor 124 may be directly connected to alarm system 130, although this direct connection avoids some of the benefits of having the inventive alarm interface 200 in place between them.
  • the alarm interface 200 receives power from an external source such as alarm system 130 on path 160, although of course this is not a requirement of the invention. Based on its monitoring of the condition of the keypad, lock, lock bolt, motion detector, door sensor (and any other elements), the alarm interface provides several outputs, most of which are provided to alarm system 130.
  • Alarm system 130 may be of conventional design. Generally, such an alarm system 130 is connected to a control unit 132 that allows a user or other automated system to enable or disable the alarm system, or perform other programming tasks that the particular alarm system permits. Also, an alarm system normally operates with a display console 134 that provides visual or audible indications of the status of the alarm system or the area it protects. A common feature of alarm systems is an auto-dialer 136 that can telephone the police or a private security force in the event of an alarm condition. The alarm system can have many other components (not shown), including monitoring devices (such as motion detectors, still or video cameras, door position sensors, and the like), other display devices (local or remote), and other communication devices (such as a modem, audible or visible alarm, and so forth). In short, the details of the alarm system implementation are not essential to the inventive alarm interface 200, and further discussion not necessary.
  • the alarm interface 200 provides one or more bolt status indicator signals on paths 162. 164 to the alarm system 130, and are described in greater detail below.

  • a "disarm/enable” signal is provided on path 166 to the alarm system.
  • a “disarm” value of this signal indicates that the alarm system should not be recognizing an alarm condition (at least as far as interface 200 is concerned).
  • the "enable” value of the signal indicates that (as far as the interface 200 is concerned) the alarm system should be capable of recognizing an alarm condition associated with the interface.
  • the inventive alarm interface 200 provides more intelligently processed status information to the alarm system so that the alarm system's actions are commensurately more intelligent.
  • a conventional alarm interface might signal an alarm condition any time door 1 is opened, requiring a user to remember to disable the alarm system each time before he opens the door routinely using the keypad 1 12.
  • the inventive interface recognizes that opening the door using a proper combination entry at keypad 1 12 is a routine event that should not invoke an alarm condition, and, accordingly, the inventive interface does not signal an alarm condition when the door is sensed to be open after a routine correct combination entry.
  • the inventive interface also provides a VCR Control signal on path 168 to a visual image recording device such as video cassette recorder (VCR) 140.
  • VCR 140 continuously receives video signals from (for example) a video camera 142 that normally views the unprotected area 3 immediately outside the protected area 2.
  • VCR Control signal When the VCR Control signal is activated, the VCR records the video signal form camera 142, but when the VCR Control signal is inactive, the VCR does not record.
  • the inventive interface can intelligently reduce the amount of time that the VCR is recording, thus reducing the demand to store video cassettes and minimizing the amount of time security personnel must review the tapes in order to inspect an event of interest.
  • the inventive alarm interfaces activates the VCR Control signal for a period of time (such as ten seconds) after any key on keypad 112 is pressed (provided that the bolt extended at the end of the ten-second period).
  • This activation of the VCR Control signal causes anyone attempting to tamper with the keypad to be captured on video tape, while minimizing the amount of video tape that is consumed by routine openings of the lock by authorized individuals.
  • the inventive alarm interface can activate the VCR Control signal for given periods of time, in response to conditions than pressing of a key on the keypad (such as a signal from motion detector 122. a door sensor 124, or bolt retraction signal 102).

  • a preferred embodiment of the inventive interface is designed to avoid needless false alarms and unnecessary consumption of video tapes and inte ⁇ rets these other inputs appropriately before signalling the alarm system or VCR.
  • the inventive alarm interface 200 also provides G and R indicator signals on paths 170. 172 to a lock status panel 150, which may be located near the door or, alternatively, in a remote monitoring post.
  • Lock status panel 150 has green and red indicator LEDs 152. 154 that are illuminated in response to the G and R signals, respectively.
  • the G and R signals are provided when the lock's bolt is extended (to lock the door) and retracted (door unlocked), respectively.

  • the motion detector signal on path 123 and the door sensor signal on path 125 pass through respective buffers 223, 225 that filter and condition the respective signals to make them compatible with the microcontroller's inputs.
  • a conventional opto-isolator 216 extends with a current-limiting resistor between +V on path 208 and the beep/LED signal on path 206 so that the microcontroller can recognize when a beep/LED signal is being sent, without interfering with the signal.
  • a conventional regulator 260 provides an interface between the alarm system voltage signal 160 and the power input of the microcontroller.

  • the flow charts refer to operation of the device at a high level of functionality rather than referring to non-essential details of implementation; for example, the flow charts refer to whether the "lock is locked” rather than to whether the '"bolt extended' sensor is closed.” This is to emphasize that the functional operation of the device does not demand the particular hardware implementation that is described above, and that the scope of the invention should not be limited to disclosed embodiments.
  • FIG. 3 is a high-level flow chart indicating major functional features performed by the inventive alarm interface. After the alarm interface is powered up (at 310), an initialization routine 320 is executed.

  • FIG. 2 microcontroller 210
  • routines are illustrated in a given order in FIG. 4, it is envisioned that the order in which the routines are executed may be varied in accordance with principles known to those skilled in the art. Further, it is envisioned that the functions performed by the routines may be performed in parallel rather than in series, depending on the hardware architecture of the system involved. Moreover, one or more of the described routines may be omitted, and additional routines may be included, while still remaining within the scope of the invention. Accordingly, it is to be understood that the following functional descriptions are made by way of illustration and do not limit the scope of the invention.
  • Control enters the routine and a decision block 610 determines whether there has been a change in the position of the lock ' s bolt since the last time this decision block has been visited. If there has been no change in the position of the bolt (retracted-to-extended, or extended-to-retracted), then control pass directly out of routine 600. However, if it is determined that there has been a change in the position of the bolt, then control passes to a decision block 620.
  • Decision block 620 represents the microcontroller ' s determination of whether the bolt is being retracted. This may be determined by reading whether the "extend" signal on path 102 from the lock has just been deactivated. If it is determined that the bolt has not just been retracted (indicating that the lock is locked), then control passes directly to decision block 640.
  • Block 622 indicates the microcontroller's sending of a "disable alarm” signal on path 166 (FIGS. 1 and 2).
  • block 624 indicates the microcontroller's setting of an internal "alarm timer" to a predetermined time interval (one second in the preferred embodiment).
  • the alarm timer ensures that, for the given time interval, the alarm system receives a disarm signal of sufficient duration to disable the alarm before receiving a bolt retraction signal, and does not treat a routine authorized bolt retraction as an alarm condition. This feature prevents false alarms when people fail to disarm the alarm system before unlocking the safe.
  • control passes to decision block 640.
  • Decision block 640 indicates the microcontroller's comparison of the two signals received from the lock, the "extended” signal on path 101 and the "retracted” signal on path 102 (FIGS. 1 and 2). Three comparison results are possible, as follows. First, if the "retracted” signal is active but the "extended” signal is not active, this indicates that the bolt is retracted; in this event, control passes to block 642, in which the microcontroller repeatedly toggles the R signal on path 172 (FIGS. 1 and 2) and a red light flashes on the status board 150. Second, if conversely, the "retracted” signal is not active but the "extended” signal is active, control passes to block 644.
  • the microcontroller repeatedly toggles the G signal on path 170 (FIGS. 1 and 2) and a green light flashes on the status board 150.
  • the two signals are the same, an anomalous or temporary condition is occurring; in this event, the R and G signals are alternately activated to cause both the red and green lights to flash.
  • blocks 646 or 650 control passes from the bolt sensing routine.
  • VCR control routine 700 Control enters the routine and enters decision block 710.
  • Decision block 710 indicates the microcontroller's determination of whether the VCR timer (set in block 520 in FIG. 5) has expired. If the VCR timer has not expired, control passes directly out of the VCR control routine 700 so that the VCR 140 (FIG. 1) continues to record.
  • Control enters the routine and enters decision block 810.
  • Decision block 810 indicates the microcontroller's determination of whether or not the bolt status delay (set in FIG. 6 block 646) has expired. If the bolt status delay has not expired control passes immediately out of bolt status delay routine 800. However, if the bolt status delay has expired, control passes to block 820. In block 820, the microcontroller outputs on paths 162, 164 the bolt status, either locked or unlocked (as had been determined in FIG. 6 block 640) before exiting the routine. In this manner, the status of the bolt is not reported to the external alarm system 130 until after a given time period (such as a half-second) after the bolt is either retracted or extended.
  • a given time period such as a half-second
  • This half-second delay in reporting changes of the position of the bolt ensures that the alarm has adequate time to be disabled by a disarm signal on path 166, so that the bolt status does not erroneously trigger what the external alarm system 130 may wrongly consider to be an alarm condition.
  • Decision block 910 reflects the microcontroller's determination of whether or not the internal alarm timer (set in FIG. 6 block 624 to be one second) has expired. If the alarm timer has not expired, control passes directly out of the alarm timer routine. However, if decision block 910 determines that the alarm timer has expired (indicating the end of the exemplary one-second alarm timer interval), control passes to block 920.
  • Block 920 indicates the microcontroller's activating of the alarm enable signal on path 166 (FIGS. 1 and 2).

Accordingly, the particular manner of implementing the above-described functions is not essential to the invention that is claimed, and the scope of the invention should not be limited except by the language of the claims.

  • the bolt position signal is deactivated the same short time period after the "extended” signal 101 is activated. In this manner, the signal indicating the position of the bolt is delayed by one-half second to allow the disable alarm signal 166 to prevent false alarms.

Abstract

Une interface intelligente entre un système de serrure et un système d'alarme (130) surveille l'état de divers points relatifs au système de serrure et à la zone associée à ce dernier. L'interface (200) surveille si le pêne de serrure(100) est rentré ou sorti, si une tentative d'ouverture de la serrure (124) est en cours, si la porte fermant une zone protégée est ouverte ou fermée (150), si un détecteur de mouvement (122) a détecté la présence d'une personne et ainsi de suite. L'interface (200) de l'invention interprète intelligemment les conditions entrées dans celui-ci, en informe le système d'alarme (130), commande d'autres dispositifs et fournit des informations aux dispositifs d'affichage (134). La surveillance et l'interprétation intelligente (200) assurées par l'interface permettent de réduire les occurences de fausses alarmes, comme c'est le cas lorsqu'une personne autorisée débloque la serrure(100) comme à son habitude mais sans désactiver le système d'alarme. Par ailleurs, une commande mieux adaptée d'autres dispositifs de surveillance, tels qu'un magnétoscope (140), est prévue de sorte que des images vidéo ne soient enregistrées que lorsque certains événements déterminés surviennent. L'enregistrement commandé intelligemment (210) permet ainsi la réduction au minimum de du volume de mémoire nécessaire pour les enregistrements vidéo et de réduire le temps requis pour que le personnel de sécurité localise un événement intéressant sur la bande.
