Definitions

  • the invention relates to an alarm arrangement with a monitoring unit arranged on a movable glass pane or door to be monitored, with an alarm transmitter and with a fixed distributor which is inductively coupled to the transmission unit in the desired position of the glass pane or door and which is connected to a signaling center.
  • this arrangement has the disadvantage that the current flow in the coil of the distributor also depends on other sizes, such as the width of the air gap between the cores facing one another. This air gap can change, for example due to an expansion of the window depending on the season to change.
  • the coupling between the transmission unit and distributor is very good, because with a poorer coupling, a change in the coil resistance of the transmission unit in the current flow of the distributor coil can hardly be measured.
  • the coil current of the distributor coil is further influenced by the temperature drift of electrical components in the distributor.
  • separate transmission means for energy supply and information are required.
  • the distributor for the inductive coupling to a resonant circuit of the transmission unit has its own resonant circuit, which is connected by a clock-controlled changeover switch in a first switch position to a first oscillator to work as a transmitter, and one second switch position is connected to a signal evaluation circuit for signals emitted by the transmission unit in order to work as a receiver.
  • the distributor coil of the resonant circuit of the distributor works as a transmitter and induces an alternating voltage in the coil of the resonant circuit of the transmission unit.
  • the first oscillator arranged in the distributor generates a high-frequency signal which lies in the range of the resonance frequency of the resonant circuit of the distributor and the transmission unit. After a little more than half a cycle period, the clock-controlled toggle switch is switched to the second switch position.
  • the oscillating circuit of the transmission unit When the alarm device is in the normal state, the oscillating circuit of the transmission unit continues to oscillate for a short time induces an AC voltage in the resonant circuit of the distributor, which is fed to the signal evaluation circuit which is now switched on.
  • the signal evaluation circuit interprets this ringing as an acknowledgment signal, which characterizes a desired position of the transmission unit relative to the distributor and a normal state of the alarm transmitter.
  • the oscillating circuit of the transmission unit can be interrupted or short-circuited, whereby the oscillation of the oscillating circuit of the transmission unit and thus the acknowledgment signal is avoided.
  • the acknowledgment signal also remains off if the transmission unit is not in its target position (eg with the window open).
  • the transmission unit has a further two-way switch which, in a first switch position, has the resonant circuit provided for inductive coupling to the resonant circuit of the distributor with a signal detector circuit for a signal emitted by the distributor and a second switch position with a signal generating circuit for emitting an acknowledgment signal connects.
  • the transmission unit is then switched over in synchronization with the clock-controlled changeover switch of the distributor between a receiving and a transmitting state.
  • the transmission unit has a signal detector circuit which detects whether a voltage is induced in the resonant circuit of the transmission unit by the resonant circuit of the distributor.
  • the signal detector circuit remains connected to the resonant circuit of the transmission unit and the induced voltage of this resonant circuit is fed via a diode to a buffer capacitance to build up an operating voltage. If the signal detector circuit detects that after switching over the clock-controlled toggle switch of the distributor, no more voltage is induced in the resonant circuit of the transmission unit, it outputs a signal to the signal generation circuit for generating an acknowledgment signal and simultaneously switches the signal generation circuit to the voice coil of the transmission unit. A in the signal generating circuit monostable multivibrator generates a control signal with a fixed time t3 for a downstream oscillator.
  • the oscillator leads for the duration t3 of the control signal to the oscillating circuit an AC voltage signal, which is interpreted by the signal evaluation circuit of the distributor as an acknowledgment signal.
  • the signal detector circuit only triggers the oscillator of the signal generating circuit when the alarm transmitter is in the normal state at the same time. If the alarm device is triggered, the oscillator of the signal generating circuit is not triggered, and thus the acknowledgment signal is not emitted.
  • the signal evaluation circuit of the distributor then assumes an alarm state of the alarm transmitter.
  • the acknowledgment signal is also not output if the resonant circuit of the distributor and the resonant circuit of the transmission unit are moved far apart, which is the case when the window is opened or when the transmission unit is violently removed from the window.
  • an alarm state is also assumed by the signal evaluation circuit of the distributor.
  • An advantage of this development of the invention is the fact that a signal with a defined frequency is emitted as the acknowledgment signal, which signal can be clearly interpreted as an acknowledgment signal in the signal evaluation circuit of the distributor. This detection of the signaling state of the alarm transmitter works much more precisely than a measurement of the coil current of the distributor which is dependent on many parameters.
  • the signal generation circuit has an oscillator arrangement which emits an acknowledgment signal, the frequency of which is dependent on the output signal of the alarm transmitter. If the status of the alarm transmitter changes, the oscillator of the signal generating circuit is therefore not switched on, but an acknowledgment signal with a frequency that differs from the frequency of the signal in the normal state of the alarm transmitter is fed to the voice coil of the transmission unit and thus to the distributor.
  • This can be realized, for example, by arranging two oscillators connected in parallel, which are switched on by the alarm transmitter and the monostable multivibrator via upstream AND gates. One oscillator is switched on when the alarm transmitter is in the normal state and the other oscillator is switched on when the alarm transmitter is in the alarm state.
  • FIG. 1 illustrates the inside of a window sash 6 which is installed in a wall 2 and is pivotably articulated via hinges 4.
  • This sash comprises a glass pane 8 and a window frame 10.
  • An alarm arrangement e.g. a glass break detector, which is provided with the reference number 12, serves to record and evaluate the signaling states of an alarm transmitter and / or the opening state of a window. It consists of two separate parts, namely a monitoring unit 14 on the window sash 6 and a wall-side distributor 16, which is connected to a reporting center (not shown) via supply lines 18 and reporting lines 20. A large number of such alarming arrangements can be connected to the signaling center.
  • the monitoring unit 14 comprises a passive glass break sensor 22 which is glued directly onto the glass pane 8.
  • An electronic circuit arrangement 24 is connected downstream of the glass break sensor 22 and processes the output signals of the glass break sensor 22 for further processing. It is connected to a coupling electronics 26, via which a wireless exchange of energy and information to the distributor 16 takes place.
  • the monitoring unit 14 is arranged on the edge of the glass pane 8 or the window sash 6.
  • the distributor 16 is located directly opposite the coupling electronics 26, so that the wireless transmission path is kept as short as possible.
  • this transmission path is interrupted, for example by the fact that the monitoring unit 14 has been improperly removed, that it has detached itself automatically from the glass pane 8 or that the window sash 6 is open, this condition is determined by the control center via the detection lines 20. If the alarm center is armed, the alarm center triggers an alarm. In the unset state, arming is hereby excluded because the glass break detector 12 cannot work properly.
  • the function of the glass break detector 12 is described in detail below with reference to the block diagram in FIG. 2.
  • the distributor 16 contains an oscillating circuit 28, which consists of a parallel connection of a first coil 30 and a first capacitance 32.
  • One connection of the resonant circuit 28 is at ground (0V), while the other connection is connected to a clock-controlled changeover switch 34 which is switched between a first switch position and a second switch position by a clock generator 36.
  • the resonant circuit 28 of the distributor 16 is connected to a first oscillator 38 which emits a higher-frequency output signal f 1 than the clock frequency of the clock generator 36, which is in the region of the resonant frequency of the resonant circuit 28.
  • the distributor 16 works as a transmitter and the transmission unit 14 coupled via the coupling electronics 26 as a receiver in the manner described below.
  • the distributor 16 functions as a receiver and the transmission unit 14 functions as a transmitter in the manner described in more detail below, the signal evaluation circuit 40 receiving an acknowledgment signal from the transmission unit 14 received by the resonant circuit 28 of the distributor 16 for derivation evaluates an alarm or non-alarm signal.
  • the signal evaluation circuit 40 has at its input a voltage detector circuit 42 which rectifies the signals induced in the voice coil 28 of the distributor 14.
  • the output of the voltage detector circuit 42 is connected to a switching stage 44 designed as a bistable multivibrator.
  • the output of the bistable multivibrator 44 leads via a first diode 46 and a first resistor 48 to an integrating RC element which consists of a second resistor 50 and a second capacitor 52.
  • the binary signal coming from the bistable multivibrator 44 is thus integrated into an analog signal by the RC element 50, 52, which is led to a second switching stage 54 with Schmidt trigger behavior.
  • the output of the Schmidt trigger 54 switches from logic high to logic low and thus causes a light-emitting diode 56 and a relay 58 to be switched on, which closes a line circuit of the alarm lines 20 connected to the alarm center.
  • the alarm center detects an alarm state of the glass break sensor 22 and the measures provided for this can be initiated.
  • the transmission unit 14 is coupled with its own resonant circuit 60 to the resonant circuit 28 of the distributor 16 when the window sash 6 on which the transmission unit 14 is arranged is closed.
  • the resonant circuit 60 of the transmission unit 14 consists of a third capacitance 62 and a second coil 64.
  • This resonant circuit 60 is connected by a further changeover switch 66 in a first switch position to a signal detector circuit 68 and in a second switch position to a signal generating circuit 70.
  • the clock-controlled changeover switch 34 of the distributor 16 When the clock-controlled changeover switch 34 of the distributor 16 is in its first switch position and the first oscillator 38 is connected to the oscillating circuit 28 of the distributor 16, the further changeover switch 66 of the transmission unit 14 is also in the first switch position shown.
  • the voltage signal induced by the resonant circuit 28 of the distributor 16 in the second coil 64 of the transmission unit 14 is applied to a second voltage detector 72 located at the input of the signal detector circuit 68.
  • the voltage signal is converted there into a DC voltage signal and fed to a third switching stage 74, which is designed as a comparator and compares the DC voltage signal with a reference voltage.
  • the voltage signal induced by the second coil 64 is also applied via a second diode 76 to a buffer capacitance 78, which provides the operating voltage for the signal detector circuit 68, the signal generation circuit 70 and the glass break sensor 22 for a limited period of time.
  • the voltage is not induced signals in the second coil 64, for example because the clock generator 36 switches the clock-controlled toggle switch 34 of the distributor 16 from the first switch position to the second switch position, the DC voltage present at the output of the second voltage detector 72 drops. If it falls below a predetermined value, the comparator 74 switches the further changeover switch 66 and supplies an input of the signal generating circuit 70 with an enable pulse.
  • a monostable multivibrator 80 arranged at the input of the signal generating circuit 70 is triggered by the release pulse only when the glass break sensor 22 connected to a further input of the monostable multivibrator 80 is in a normal or non-alarm state.
  • an oscillator 82 arranged downstream of it is activated for the switching period t 3 of the monostable multivibrator 80.
  • the output signal of the downstream oscillator 82 is then fed to the resonant circuit 60 of the transmission unit 14 as an acknowledgment signal.
  • the voltage signal thereby induced in the resonant circuit 28 of the distributor 16 is then evaluated in the signal evaluation circuit 40 of the distributor 16 in the manner already described.
  • the operating voltage supplied by the buffer capacitance 78 has dropped so far that the comparator 74 falls back into its starting position and switches the further changeover switch 66 into the first switch position. It is also possible to switch the further changeover switch 66 into the second switch position by means of a monostable multivibrator, as a result of which the switch back to the first switch position would take place automatically after a predetermined time (not shown).
  • FIG. 3 schematically shows the structure of a signal generation circuit 84 which, like the signal generation circuit 70 from FIG. 2, is provided for generating an acknowledgment signal as a function of the output signals of the signal detector circuit 68 and the alarm transmitter 22.
  • a signal generation circuit 84 which, like the signal generation circuit 70 from FIG. 2, is provided for generating an acknowledgment signal as a function of the output signals of the signal detector circuit 68 and the alarm transmitter 22.
  • identical circuit parts are provided with identical reference numerals.
  • the signal detector circuit 68 detects a change in the activity of the distributor 16 from the send to the receive function, the signal detector circuit 68 emits a pulse which causes the monostable multivibrator 80 to emit an output pulse with a predetermined time t 3.
  • This output pulse is applied to the first inputs of two downstream AND gates 86,88 connected in parallel.
  • the output signal of the alarm transmitter 22 is applied to the second input of the first AND gate 86 and the inverting second input of the second AND gate 88.
  • the first AND gate 86 is connected to a first oscillator 90 and the second AND gate 88 is connected to a second oscillator 92.
  • the oscillation frequency of the two oscillators 90, 92 is different from one another.
  • the outputs of the two oscillators 90, 92 are brought together and can be connected to the resonant circuit 60 of the transmission unit 14 via the further changeover switch 66.
  • either the first oscillator 90 or the second oscillator 92 is triggered for the trigger time t 3 of the monostable multivibrator for the time t 3 to emit an acknowledgment signal.
  • the distributor 16 can then recognize by means of a signal evaluation circuit which detects the frequency of the acknowledgment signal whether the detector is in the triggered or non-triggered alarm state.
  • the signal evaluation circuit 40 of the distributor 16 is able to distinguish whether a window is open (no acknowledgment signal), whether the window is closed and the alarm transmitter reports a normal state (delivery of a Acknowledgment signal with a first frequency by the first oscillator 90) or whether the window is closed and the alarm transmitter reports an alarm state (delivery of an acknowledgment signal with a second frequency by the second oscillator 92).
  • oscillator arrangement with many to measure the analog measured value, for example of a vibration detector perform oscillators connected in parallel with different oscillation frequencies. These oscillators would then have to be individually controlled via an upstream A / D converter. It would also be possible to use an oscillator adjustable in frequency by an analog control, which would then be triggered directly by a monostable multivibrator and the alarm device, the oscillation frequency being set by the analog output signal of the alarm device.
  • the different frequencies could be evaluated directly in the signal evaluation circuit of the distributor to derive an alarm or non-alarm state. However, it is also conceivable to transmit the signals of different frequencies present at the signal evaluation circuit to the signaling lines to the signaling center for evaluation there.
