Definitions

  • This invention relates to recording apparatus and more particularly to a device for identifying patrols made by security personnel.
  • SUBSTITUTE SHEET In terms of the accompanying block diagram it may basically comprise a light sensitive diode or pulsed infrared sender unit 1 which is adapted to be mounted inside a window.
  • an event logger circuit 2 is fed into an event logger circuit 2 and thence to a memory circuit 3 where it is stored agaist a specific date and time as provided by clock 4.
  • a liquid crystal display 5 is also incorporated into the recorder so that the user may subsequently observe the date and time for each of a series of prior recorded events ie. security patrols.
  • provision may also be made for hard printouts of event times and dates.
  • an inhibiting switch 6 may also fitted. This prevents separate recordal of events less than say one minute apart.
  • the memory circuit 3 is not limited to any specific capacity it is envisaged that an abitity to record and store data for several patrol events per day over a two week period would be sufficient for most applications.
  • Adhesive strip 45 x 15 mm, 3 mm from top and bottom
  • Memory Record 256 events, with date and time Clock: Resetable " date and time
  • Light Sensor Light sensitive diode
  • the client At the end of a selected period the client would then be able to confirm that the contracted number of patrols have in fact taken place by simply activating the readout through either the liquid crystal display or printout.
  • the electronics are mounted on two printed circuit boards, one for the display, mounting LCD1 and U3, and the other for the remaining electronics, mounting Ul, U2, U4 , U5 and their associated components .
  • the keypad mounts on the back panel .
  • 68HC11 microprocessor Ul operating from an 8 MHz crystal XI.
  • the 68HC11 is configured for single chip mode, having no external address and data lines.
  • This microprocessor has onboard a 2K X 8 EEPROM which can be written to and read by the microprocessor and is non-volatile, allowing storage of events .
  • a real time clock is provided by U4 , operating from a 32.768 KHz crystal X2. Date and time setting and reading is carried out from the microprocessor via serial lines CLK, SIO and SRST. This RTC is battery backed with battery Bl to give a 10 year clock data retention. During normal operation this battery is trickle charged from the system power line via Dl and R6.
  • a four digit data display is provided by the LCD display LCD1 and its controller chip U3. This chip continually scans each segment of each digit of the LCD, updating its display. Data to be displayed is entered into the controller chip by the microprocessor on lines Dl to D , whilst DSl to DS4 are used to set the digit to be updated with this data.
  • An event detector is provided by light detection diode D3 and its associated amplifier U5.
  • the output of this amplifier is fed to the microprocessor onboard A-D converter via line PS.
  • the microprocessor continually monitors this line, converting the analog signal to an 8 bit digital value. Over a period of time a background light level is established that provides a reference against which a guards torch is compared.
  • Event and Power indications are provided by LEDs LI and L2, driven from the microprocessor by lines EV and PO. In case of external power failure when the unit runs from battery these LEDs can be turned off to conserve power .
  • This unit On power up the system hardware is set to a known state by the reset circuit provided by U2 and the reset switch SI.
  • This unit also contains a watchdog which may be enabled by strapping LKl pins 2 and 3 or disabled by strapping LKl pins 1 and 2.
  • the processor When the watchdog is enabled the processor will provide pulses on line WD to keep the watchdog from timing out and resetting the system,
  • this invention at least in the form of the embodiment disclosed provides a novel and unique improvement to existing methods for recording security patrols.
  • the example described is only the currently preferred form of this ' invention and a wide variety of modifica ions may be made which would be apparent to a person skilled in the art.
  • the invention extends to other electrically equivalent types of circuits and is not limited to any particular design of housing for the apparatus. Apparatus may also within the scope of this invention be adapted for use in applications outside the security industry .

Abstract

Appareil d'enregistrement et d'affichage photosensible d'heure et de date, conçu pour être monté derrière une paroi transparente en un endroit choisi afin d'enregistre les heures et les dates auxquelles des patrouilles de sécurité sont effectuées. L'appareil peut être activé par une torche portative du type porté par le personnel de sécurité. Le détecteur de passage de patrouille de l'appareil peut comprendre une diode photosensible ou un organe (1) émetteur à infrarouge et à impulsions monté derrière une fenêtre. Le signal provenant du détecteur (1) est introduit dans un circuit de mémoire (3) où il est mémorisé par rapport à une heure et une date spécifiques fournies par l'horloge (4). Un affichage à cristaux liquides (5) est également incorporé dans le dispositif d'enregistrement afin que l'utilisateur puisse ultérieurement vérifier l'heure et la date de chacune d'une série de patrouilles de sécurité précédentes.
