Definitions

  • the invention relates to an alarm glass pane unit, a System composite of such alarm glass pane units and a Method for operating such a system network.
  • Such alarm glass units are generally based on the principle of operation, that facing on one of the inside Side of the disc, e.g. the inside of a single pane safety glass pane (Tempered glass), an alarm conductor loop e.g. is applied by screen printing.
  • the disc crumbled upon formation of a crack such as e.g. in places or attempted penetration of the disc always arises, exploding over the entire disk under training very much small glass fragments.
  • By destroying the whole Disc surface becomes the alarm conductor loop, even if it is from The point of violence is more distant and relative has small dimensions, destroyed, so that they are interrupted will or will change their resistance significantly.
  • the change of the resistance value This is generally directly as an alarm signal evaluated.
  • DE-PS 12 78 292 shows an insulating glass unit with a ESG disk facing on the disc space Inside carries an alarm conductor loop, which via connecting wires with a running outside of the disc, too an alarm transmitter leading line is connected.
  • alarm glass panes in a facade arise serious Disadvantages of this wiring.
  • the connection between an alarm glass and the to the Alarm device or an alarm center leading line system produced by a four-pin connection cable, which is connected to a End with the alarm glass, usually by a soldering of the Cable is connected to the alarm conductor loop, and on the other end has a plug connection to the line.
  • Two Phases of the cable are provided as a backup, the one Prevent bridging of the alarm conductor loop.
  • EP 0 058 348 A2 shows an alarm glass pane on which Inside an alarm conductor loop widened at their ends Pads is applied to the connecting wires are soldered.
  • the widened connection surfaces for the connection wires are in the outside of the distance frame lying Edge area of the toughened glass pane arranged and with the alarm conductor loop connected by line sections passing through the Covered metallic spacer frame or a protective layer are led to the outside.
  • the alarm conductor loop thus serves as Breakage sensor and as a supply line in the critical area of the edge seal.
  • DE 43 90 350 A1 describes an alarm transmitter arrangement with a coupled resonant circuit of a capacitor and a Kitchen sink.
  • the alarm device arrangement thus has one arranged in a movable element sensor-side resonant circuit and a stationary arranged Transmitter circuit, wherein a change in position of the movable Elementes by determining the energy consumption of the transmitter side Oscillatory circuit is detected.
  • Actuator for the Alarm is thus the power change in the inductive coupling two oscillating circuits.
  • Such inductive coupling can occur with other systems through the contacting Partially resolve problems; however, it is e.g. an unauthorized Coupling of another signal with subsequent destruction the glass panel carrying the alarm loop is possible.
  • a separate query of each window is also one larger glass window composite required by their own leads.
  • a general disadvantage of known alarm glass is at larger facades in their elaborate wiring with the alarm or the alarm center to see there, even if respectively a group of alarm glass panels connected in series to one Line is connected, a very thick wiring harness with a Lead per alarm glass group by often very long cable ducts must be performed and in later stages often not is more accessible. Such many lines also increase the Danger of cable breaks.
  • DE-US 28 09 436 describes a fuse arrangement for Glass panes with a capacitive coupling, in which an electric conductive border of the glass sheet as a covering of a capacity is switched on when approaching, touching or breaking Signal triggers. Even with such a system is not specific Detection of individual glass pane units in a larger one Composite possible.
  • the invention is based on the object over existing Systems to create improvements and in particular one to enable reliable detection of a breakage of the glass pane.
  • the invention is thus a coupling of three antennas provided, namely one outside the glass of the unit primary antenna, one running on the glass, at break of the glass pane destructible secondary antenna and a tertiary antenna connected to the transponder. At break The glass pane thus becomes the connection between the primary antenna and tertiary antenna interrupted.
  • As an actuator thus serves the Receiving the response signal of the transponder to the interrogation signal and not the output signal of e.g. capacitive or inductive sensor.
  • a Transponder with its own, unique, specific identifier provided that can not be changed, so that specific Queries and an accurate identification of the unit also in one larger composite are possible.
  • the transponder generates here advantageously a digital signal due to the specific Identification, so a bridging or abusive Replacement by an externally applied, inductively coupling System is not possible.
  • an encryption or cryptic ciphering of the transponder signal is not possible.
  • the transponder an analog query signal receives and outputs an analog response signal.
  • the analog response signal can z. B. processed in the primary antenna be, preferably a resistance of the entire unit set depending on the result determined so that the entire unit will fail if the transponder signal changes their resistance.
  • the alarm glass pane unit according to the invention can be with or be formed without a frame. It can e.g. a frameless Glass door and / or a laminated glass pane with a glass pane and a plastic film applied thereon between which the transponder is arranged with Tertiärantenne.
  • the alarm glass pane unit an insulating glass pane unit with an outer pane, a Inner pane and a space formed between them be, wherein at least the outer pane of the thermal prestressed safety glass is made and on its the intermediate space facing the secondary secondary antenna is attached, and arranged the transponder in the space is.
  • the primary antenna outside be provided of the space.
  • the primary antennas may be ferrite antennas or rod antenna coils be. They can be connected in series and from one common high-frequency data line are supplied. At a serial circuit is the query of the various transponders about their specific identifiers required, with the query the identifiers then pulsed over a multiplexer. Furthermore, the primary antennas can also be connected in parallel be queried and via separate cables.
  • the tertiary antenna can carry both a rod and a coil or ferrite antenna.
  • the secondary antenna runs advantageously such that a good coupling with both the Primary and tertiary antenna.
  • a normal operating mode for checking the alarm glass units e.g. be carried out during the day, in which a closed State of an open state, z. B. tilted, pivoted or deferred alarm glass unit, can be distinguished.
  • This opening detection can also be performed on systems which have further adjustable components without a glass substrate, e.g. Doors, flaps or hatches with corresponding antenna designs.
  • the alarm glass pane unit 1 has according to this embodiment further comprising a circumferential frame 7, through a Glasfalzmann 8 is closed to the interior.
  • the two glass sheets 2, 3 are by means of an adhesive 13, for. As silicone, glued into the frame 7.
  • a block bridge 10 is inserted on the the glass sheets 2, 3 stand up.
  • the only symbolically drawn Primary antenna can basically be a ferrite antenna or coil antenna or even a rod antenna.
  • a conductor loop Secondary antenna 18 is applied, e.g. screen-printed printed or glued on.
  • a Transponder chip 20 with a preferably designed as a conductor coil Tertiary antenna 21 glued on.
  • the tertiary antenna 21 is in this case sufficiently away from the primary antenna 22, so that she can not pick up a signal from this one.
  • the signal transmission between the primary and tertiary antenna is only through the intervening switched secondary antenna 18 possible.
  • the Transponder chip 20 with tertiary antenna 21 on one of the primary antenna 22 opposite side of the outer pane 2 is provided be, as indicated in Fig. 1a.
  • a signal transmission, however, only on the intermediate secondary antenna 18 is possible.
  • the secondary antenna 18 can span a larger area of the outer pane 2 extend or only in a small area between the tertiary antenna 21 and the primary antenna 22 be, it extends over a sufficiently large Area of the outer pane 2, so they break at the ESG outer pane 2, which is to a substantially complete Crumbling leads, is destroyed, causing the signal transmission interrupted by the alarm center 14 to the transponder chip 20 becomes.
  • FIGS. 2a, 2b, 2c show advantageous embodiments, in which each Tertiärantenne 21 formed as a coil is and transponder chip 20 and the tertiary antenna 21 in one circular area of the secondary antenna 18 is arranged are, wherein in Fig. 2a, b, the position of the transponder chip 20 and the tertiary antenna 21 is only hinted at.
  • - Primary antenna 22 extends the secondary antenna 18th as in Fig. 2b, c all along the edge of the disc 2 or how in Fig. 2a partially at the edge of the disc. 2
  • the transponder chip 20 is a passive transponder without its own Energy source. Thus, the energy is only from the alarm center 14 generated, via the radio frequency data line 12, Primary antenna 22 and the secondary antenna 18 as a signal to the Tertiärantenne 21 and thereby passed to the transponder chip 20.
  • a specific identifier is stored, for processing by the alarm center 14th output signal is used, so that a digital Response signal output from the transponder chip 20 and over the Tertiärantenne 21 and the secondary antenna 18 from as well Receiving device serving primary antenna 22 is received.
  • This signal can also be cryptically encoded.
  • Alternatively to this is also a signal recording via an additional primary receiving antenna possible to send the recorded signal to the alarm center 14 passes.
