Definitions

  • the invention relates to an electrical burglar protection device with a circuit for generating signals for switching on and off at least one electrical consumer according to the preamble of claims 1 and 2 respectively.
  • An electrical burglar protection device according to the preamble of claim 1 is known, for example, from FR-PS 2 585 482, in which a multiplicity of switches controllable via a programmable circuit is arranged between a collecting line and the individual lines leading to the consumers via fuses. It is considered a disadvantage of this burglar protection device that the circuit and the large number of switches in existing house distribution systems can only be installed by a specialist with considerable technical effort.
  • a disadvantage of such random circuits is that the individual consumers that are to be controlled are individually connected to the random circuit via power cables must be closed.
  • the random switching at the central point of the apartment or house is connected to a mains connection via a cable, and the consumers connected to it are controlled via individually laid cables. This results in a not inconsiderable need for cable lengths, especially for consumers far away.
  • Laying, connecting and re-stowing the random switch and the associated cables and consumers means that, in addition to the space required for the individual parts, each time an inconvenient and cumbersome procedure, so that this burglary protection is usually only used when the occupants are absent for a long time. In addition, this could be visible from the outside, in particular when wiring over several floors, so that the effect of the burglar protection device suffers.
  • the lights installed on the ceiling or on the wall cannot be controlled easily since they cannot be connected to the random switch with a cable without additional work. Additional consumers such as floor lamps, desk lamps and the like are therefore required, which means a not inconsiderable additional effort. The effectiveness of the known burglary protection is certainly worsened by the fact that not every consumer can be controlled.
  • the invention has for its object to provide an electrical burglar protection device of the type mentioned, which is inexpensive, easy to use and flexible to use.
  • random switching is to be interpreted generously. It is not only circuits that output signals that are randomly generated in a strictly mathematical sense, but also circuits that generate signal sequences with such high multi-periodicities or with so many possible combinations that when switching the consumers on and off an irregular one An impression is created for the observer, who therefore assumes that the house or apartment is inhabited.
  • electrical consumers is intended to cover all consumers that can be controlled with the random circuit.
  • these are, above all, radio and television sets of all kinds, and, as further examples, tape recorders with recorded voices or music, or motor-driven shutters or the like.
  • electrical domestic distribution device is to be understood quite generally to mean a device by means of which a main line or busbar carrying the mains voltage is distributed over a plurality of secondary lines and branches.
  • the random circuit used in the electrical burglar protection device for driving the consumer is designed in terms of size and nature so that it can be used as a replacement for a fuse that is then no longer required or in a reserve place instead of an additionally provided fuse a fuse and switch box can be installed.
  • the random circuit By installing the random circuit in a fuse box of an electrical home distribution device, there are considerable advantages over the prior art. So First, the inconvenient and time-consuming connection of the random circuit with the respective consumers is eliminated, since according to the invention the random circuit is already completely installed and connected, and only needs to be switched on if necessary.
  • the burglar protection device of the present invention also allows any electricity consumers to be controlled, for example ceiling lights, which not only leads to an improved burglar protection effect, but is also considerably cheaper than the known solution.
  • the fuse and switch box can be a distribution device for the entire house, or also the fuse box for a single apartment or separate apartment or for an even smaller section of the house.
  • the burglar protection device according to the present invention is alternatively designed for installation in conventional flush-mounted boxes of switches and sockets.
  • These refinements of the invention also have the aforementioned advantages with regard to easy installation.
  • the embodiment according to claim 2 has the advantage that it can be designed for smaller currents that enables the use of inexpensive components.
  • the random circuit When installing the random circuit instead of a fuse in the fuse box, the random circuit must be designed for the maximum permissible current of the respective fuse.
  • the circuit can be designed for the lower currents of the consumers connected or split.
  • Both variants of the present invention enable flexible use and extremely high availability.
  • the random circuits according to the invention can be retrofitted or at the same time as the electrical installation in the new building. Furthermore, both variants are inconspicuous and cannot be seen from the outside by any burglars.
  • a plurality of consumers can be switched with a flush-mounted circuit. If the random switch is installed instead of a conventional light switch, at least two consumers can usually be switched without any additional installation, since the supply line to a light switch is usually three-wire, of which only two lines or poles are required. The unused pole or the unused line can therefore be used by another consumer, e.g. B. another lamp or a socket located in the room can be used. The installation effort for this is minimal, since all electrical lines leading into a room usually open into the room at a common point under the ceiling and branch out from there and from this point or from this flush-mounted box also the lines to the respective light switches branch off.
  • the random circuit is combined with a dimmer circuit. Since circuit components of the dimmer circuit, such as. B. dimmer IC, triac, etc. can be used both for dimmer switching and for random switching, you get a device with two functions with only minor additional effort.
  • the random circuit according to the invention can be controlled via a sensor device.
  • the random switching can only take place via a twilight circuit then be turned on as soon as it gets dark. Since the time of twilight fluctuates from day to day, this form of actuation of the random switching leads to a further non-periodic component and thus to an improved effectiveness of the burglar protection device.
  • the sensor device can be actuated mechanically.
  • the mechanical sensor can be designed in such a way that it detects unauthorized changes and processes on outer shutters and windows or doors, and then actuates the random switch.
  • the sensor device can advantageously also be provided in the form of motion detectors, which are attached to the outside of the house and can detect the movement of people, for example, via infrared radiation.
  • Another possibility for controlling the random circuit via a sensor device is the possibility of remote control of the random circuit.
  • all devices are to be understood that can be actuated, for example, by a third party who is spatially far from the random circuit.
  • All of the above-mentioned embodiments of the invention are "active" burglary protection devices, since they are active, i.e. work by initiating or simulating processes that the house occupant normally performs.
  • the construction of the random circuit with a so-called zero-crossing switch is particularly advantageous.
  • the use of a zero-cross switch advantageously eliminates the chokes required for radio interference suppression in other switches.
  • a zero crossing switch also replaces a separate power supply with a transformer of the circuit according to the invention, since a Zero crossing switch can provide direct current in the order of 150 mA.
  • the random circuit is provided with an on-off switch. This measure enables the burglar protection device according to the invention to be activated in a simple manner if necessary, while the function as a fuse or switch or socket etc. is ensured in the non-activated state.
  • the random switching can be controlled via a time switch, so that it is switched on and off, for example, daily at certain times.
  • the random circuit has a random number arrangement with a memory device in the form of a PROM or EPROM in which values forming a random sequence are stored.
  • a memory device in the form of a PROM or EPROM in which values forming a random sequence are stored.
  • Such a solution is on the one hand very inexpensive and on the other hand it can be used to simulate realistic switch-on sequences. For example, the time sequence and duration can be easily simulated when a person turns on the light in the stairwell, goes to the first floor, turns on the light in the bedroom, stays in the bedroom for some time and finally returns to the living room .
  • FIG. 1 shows an electrical burglar protection device with a random circuit 1 for generating signals for actuating at least one electrical consumer 2, the random circuit 1 being arranged within or in the immediate vicinity of an electrical domestic distribution device 3.

  • the random circuit 1 controls the four consumers 2a, 2b, 2c and 2d. These loads are normally connected to the busbar 5 via the associated fuses 4c, 4d, 4e and 4f, and the random circuit 1 is switched off. If the house residents are absent for a long time, the fuses 4c, 4d, 4e and 4f only need to be opened or unscrewed and the corresponding consumers 2a, 2b, 2c and 2d switched on, so that they can only be connected to the busbar 5 via the random switch 1 . After operating a switch 9 (Fig. 2), the random circuit 1 is supplied with current from the busbar 5 and is ready for use.
  • the random circuit 1 generates a random pattern of signals on the basis of which the consumers 2a, 2b, 2c and 2d are connected to the busbar 5 via the corresponding lines 10a, 10b, 10c and 10d, and individually switched on and off in accordance with the random pattern generated will.
  • the random switch 1 is simply switched off via the switch 9 and the fuses 4c, 4d, 4e and 4f are actuated, so that the respective consumers 2a, 2b, 2c and 2d again directly from the busbar 5 with current be supplied.
  • signals on the lines 10a, 10b, 10c, 10d can directly switch the random fuses 4c, 4d, 4e, 4f on and off, as a result of which only the random circuit 1 has to be switched on.

  • the switching unit 13 has the switch 9, which is additionally controllable via a sensor device 17 arranged outside the random circuit 1. 2, the sensor device 17 is shown by way of example as a twilight detection circuit with a photosensitive resistor (LDR).
  • LDR photosensitive resistor
  • the random number generator 14 can be electrically connected to the voltage supply 12 via the switching unit 13.
  • the random number generator 14 represents a digital circuit that generates time-sequential combinations of a 4-bit code on the output side.
  • the number of possible combinations of different 4-bit codes is 16.
  • the chronological sequence of the 4-bit codes can be set internally in the random number generator 14.
  • the random generator 14 is clocked, for example, at a frequency of 100 Hz (twice the mains frequency).
  • the 4-bit code generated in the random number generator 14 is applied on the input side to the counter 15, which counts these pulses and processes them further.
  • the counter 15 is designed such that it has a specific illumination pattern on the basis of the 4-bit code entered outputs on the output side via lines 18a, 18b, 18c and 18d to corresponding driver circuits.
  • the values of the successive on-off times of the individual signals going out to the driver circuits 16a to 16d are substantially larger, preferably 15 to 120 minutes.
  • Each driver circuit 16a to 16d can be controlled individually and separately from the other driver circuits via the associated line 18a to 18d.
  • each driver circuit 16a to 16d consists of a relay Re1 to Re4 which can be controlled via a transistor T1 to T4 and which actuates a switch which connects the corresponding consumer 2a, 2b, 2c, 2d via line 10a, 10b, 10c, 10d and the connection 11 with the busbar 5.
  • the counter 15 can be designed such that shorter switch-on times are provided on certain lines, for example the line 18a, so that the corresponding consumer, for example a ceiling lamp 2a in the bathroom of the house, is generally switched on in a shorter time within the lighting pattern.
  • the counter 15 is also designed such that it is reset after a certain time (for example after four hours), and the consumers 2a, 2b, 2c and 2d are only activated again after a further, longer period of time (for example after 20 hours).
  • the times for switching the random circuit 1 on and off can also be controlled additionally via the sensor device 17.
  • the random circuit has a microprocessor with memory and program, so that the burglar protection device can be operated in a user-specific manner.
  • the point in time at which the random circuit 1 is switched on is determined by the change in the resistance value of a light-sensitive resistor when the twilight begins.
  • Movement detectors and / or mechanical sensors can also be connected to the switching unit 13, so that the random circuit 1 is activated, for example, immediately after these sensors are activated and certain consumers are switched on.
  • the random circuit 20 consists of three main components, namely a random number circuit 22, a zero crossing switch 24 and a triac 26 for switching the respective electrical consumer on and off, which is shown schematically in FIG. 3 by a resistor R L.
  • the use of triacs and also thyristors offer the advantage that they can be controlled electronically in a simple manner, but also have the disadvantage that they can generate high-frequency interference which spreads over the network and has harmful side effects, such as B. Picture disturbances on television, flickering room lighting etc.
  • the zero crossing switch 24 has six connections P1 to P6. At the terminal P1, the zero switch 24 outputs a sawtooth voltage, the frequency of which is determined by a capacitor C1, which is connected to ground and the terminal P2. The zero crossing of the AC voltage is detected via the connection P8, which is connected to the pole 29 of the AC voltage via a resistor R syn . The level of the voltages present at the connections P3 and P4 determines whether the ignition current is supplied to the triac 26 via the connection P6 or not. The necessary operating voltage is generated by the zero-cross switch 24 via the ground connection P7 and the connection P5, which is connected via a resistor R v and a diode D to the pole 29 of the AC voltage. The connections P5 and P7 are directly connected to a capacitor C2. The operating voltage V cc generated by this internal voltage supply is also used for the remaining components of the random circuit 20.
