Description

The invention relates to security systems, in which various intruders can be used to detect intruders into protected property objects, such as garden and holiday homes, guest houses, public buildings, gun depots, apartments, garages, cars and more. detectors or sensors. The quantity, type and arrangement of their individual elements make it possible to detect the appearance of an intruder in the protected area and to influence the alarm and intruder deterrent devices with their output signals. The deterrent is used to deter the intruder from intentionally altering the environmental conditions in the protected space. Examples of such measures include smoke curtains, paint splashes, bright light flashes, siren screams, annoying fluid or gas flow, and so on.

Intruder protection systems that are prevalent in many countries vary in their design, depending on the size, importance, and use of legitimate means of protection.

Known German patent no. OS 41 3310 issued to the authors of an anti-theft system. In the system, a sensor actuated electric actuator for the lever connected to the annoying gas valve valve head provides a oscillating movement and opens said valve. The sophisticated electric drive mechanism and the unsafe start-up and shutdown of the system itself do not ensure sufficient system reliability and user-friendliness.

Also known from U.S. Pat. 5,034,730; and British Patent GB-A-5,257, of the same author 2 239 970 describes a security system device that automatically starts gas when a solenoid in a special sliding bearing is pushed by an electromagnet actuated from an intrusion sensor electronic circuit, the valve head being necessarily replaced by a tube with an open end inserted into a housing nozzle the expanding opening is adapted to disperse the exhaust gas.

Such a construction is complicated and requires qualified service, and the impact of the electromagnet on the can reduces the reliability of the device.

According to the essence of the technical solution, the closest to the invention is an automatic gas injection device according to US patent no. No. 5,349,335, which triggers an annoying gas when a sensor detects a criminal act and issues a control signal. There are two holes in the front wall of the device attached to the bracket, one for inserting a dispenser, the other for electronics and electromagnet power. Instead of a standard canister valve, a solenoid valve tube with a pressure indicator attached to the rear housing wall is inserted here, just like a power supply voltage indicator light.

The main disadvantage of this device is the complexity of the preparation, the need to use special equipment to avoid unintended gas dispersion when replacing the valves in the cylinders. In addition, such a device has limited capabilities and is not suitable for the protection of larger premises, not only because of the small number of deterrents in it, but also because of the security of those using such devices. a pre-set delayed time for the on-mode standby. It must be sufficient to leave the security room, but it must not be too large to prevent the intruder from damaging the security system.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a security system with a deterrent device without the drawbacks known in the state of the art.

This problem is solved by a protective system described below, in which the actuator of the deterrent actuator comprises a rack kinematically connected to an electric motor shaft, one end of which is coupled to a free end by a lever which is interposed on a stationary axis and with a deterrent-filled dispenser valve head such that said tongue may open said valve when said electric motor is engaged and said actuator may pull said rack and free lever end from its initial position and close said valve when said electric motor to a power source connected in the opposite direction of rotation may return the rack and the free end of the lever to its original position. It also has a remote control unit control code infrared transmission circuit and a control code infrared receiver to switch the security system from on standby to delayed standby using the first code combination for infrared encoding, remote control [ a signal transmitting circuit, an intruder deterrent transponder magnetic signal transceiver utilizing a second code combination to switch the system from delayed-on to off-mode. It also has at least one intruder deterrent device remote from the main intruder deterrent that can be released.

FIG. 1 shows a security system with an intruder deterrent device, wherein the intruder deterrent device 1 with presence and movement sensors 2, a deterrent trigger device 3 with its control circuit 4 is connected to a processor 5, like the device control code infrared receiver 6, receiver transmitter 7. Power supply 8 with voltage indicator 9 connected to backup power supply 10 in case of system autonomous operation, when power supply 10 power parameters do not match. The operating and signal circuit assembly 11 is coupled to a backup power supply 10 and a processor 5 having a warning speaker 13 and an indicator 14 for determining the amount of deterrent and the voltage of the deterrent power supply. The continuous control device 15 has an infrared control code signal transmission circuit 16 with an LED. Said circuit 16 is coupled to a supply circuit 17 which comprises a power supply control circuit 18 with an LED via an output signal circuit 19 to which a control code magnetic signal transmission circuit 20 is connected to form a first control code combination from the code memory unit 21 to the output signal circuit. 19 may enter via switch 22 on request from processor 23 and modulate control code infrared transmission circuit 16 when remote control unit 15 is connected to power supply 25 of said unit 15 when button 24 is released, code memory unit 21 may form a second control unit. the remote control device 15 is brought in contact with the antenna coil 7 of the magnetic code receiver transmitter 7 of the intruder deterrent device 1 control code. The inductive communication between it and the antenna coils of the control code magnetic signal transmission circuit 20 enables the carrier high-frequency voltage to be supplied to the power supply circuit 17 through the output signal circuit 19, from which it is powered and filtered to power the CPU 23, code memory 21, and The output signal circuit node 19 can shunt the antenna coil 20 of the control code magnetic signal transmission circuit 20 via the code signal frequency transmitted by the switch and processor 23, thereby modulating the RF frequency of that coil. The infrared control code signal circuit 16, through the output signal circuit 19, may limit the maximum magnitude of the high frequency voltage induced in the antenna coil of this circuit.

Optional remote deterrent device 26 is provided with its own separate deterrent trigger device 27 with control and signaling circuits 28 to which audible 29 and light 30 beacons are connected, and an on-demand siren is connected. By switching the deterrent dispenser 31, the key-off switch 32 enables the autonomous power supply 33 to be switched off, and thus the remote remote deterrent device 26 itself. Occasionally, for the convenience of the users, system control at the entrance of the room is desired using a remote control code magnetic signal receiver 36 connected to the processor 5, whose antenna coil can receive and transmit high frequency control code magnetic signals. In this case, the magnetic code receiver of the control code contained in the deterrent device is disconnected by a switch 36. The processor 1 of the device provides for the possibility of connecting a video and audio recorder 37 which facilitates the search for criminals. The radio and / or telephone paging system connected to the processor 5 enables the event notification to be accelerated in the protected room. Additional presence and movement sensors 39 allow the controlled area of the protected room to be expanded.

The effectiveness of the security system can also be enhanced by connecting 40 additional acoustic deterrents to the processor's separate output, which in some cases can even replace the basic ones provided in the system's operating manual. If a security system with an intruder deterrent is to be entered into a protected space inside the building to which another door with a door and a person responsible for guarding it is located, a button or similar device connected to the external activation circuit of the security system may be provided. According to the effect on the system, interconnection corresponds to the intrusion response of the presence and movement sensors. The button connected to the circuit 41 can be used if the responsible person sees an intruder, for example, through a window climbing into a protected room. The bottom 42 of the housing 42 of the steel flat deterrent device 1 has threaded sleeves 43 for the screws 44 (Fig. 5) and for attaching the metal pallet 45 (Fig. 3). At the corners of the building wall or other stable support, holes are made at appropriate corners in the corners 42. Signal loudspeaker 13 attached to bottom flap 42 13. Dispenser 47 with bolts 48 attached to tray 45. Tray 45 and electric drive mechanism 49. It has a gear 52, kinematically coupled to a shaft 51 of an electric motor 50, having a lever at one end coupled to a free end. 53, the other end of which is pressed onto a stationary axis 54. Near this axis 54, the lever 53 has a tongue 55 that can interact with the deterrent ball valve 46 on the valve head 56. The tongue 55 may open the valve when it actuates the valve head 56 when the electric motor is running. 50 and the electric drive mechanism 49 may pull the rack 52 and the free end of the lever 53 from the initial position to the second position where the tongue 55 holds the valve head 56 in place while the electric motor 50 is off. The tongue 55 pressed against the valve head 56 may be released when the drive electric motor 50 coupled in the opposite direction of rotation can return the rack 52 and the free end of the lever 53 to the original position in which the valve is closed. The backup power supply 10 and the siren 31 are attached to the long edge of the metal tray 45. Below the elongated dark glass screen 58 of the electronics unit 57, a row of control code infrared receiver 6 photodiode 59, control code magnetic signal transmitter transmitter 7 antenna coil 60, power supply voltage indicator LED 9 and digital deterrent indicator 14 are mounted in a row in control box 58. The larger hood of the enclosure 44 is equipped with lenses and antenna for infrared and SAD sensors 2. The deterrent outlet box 61 is provided at the corner of the enclosure 44 at the valve head 56 of the dispenser 46.

FIG. 6 shows a metal tray 45 'of an additional remote deterrent device 26 on which is mounted a deterrent actuator similar to the device mounted in the intruder deterrent device 1. The structure comprises the same functional units and details, see Figs. , rack 52 ', lever 53', axle 54 ', tongue 55', balloon 46 ', clamp 47', siren 3Γ and others. The position of the power supply 10 'and the dimensions of the electronics unit 57 are different. The additional remote deterrent device 26 is incorporated into a relatively smaller housing having a structure similar to that of the device 1.

FIG. 7 shows a remote control 15. The infrared transmitter control button 24 and the power supply 25 indicator 64 are embedded in the cover 63 of the casing bottom 62. The infrared diode 65 and the control code magnetic transmission roller are mounted in the rear region of the housing.

The system is powered by remote control via infrared signals. Receiver 6 transmits the photodiode output signal to processor 5 and, after a set time sufficient to leave the protected room, transmits the system to a ready standby mode where the sensor output signals can trigger a deterrent trigger 3 if after a set time the sensors 2 detect presence and movement. in a secured room. When activated, the deterrent device 3 operates for a set period of time and turns on again if, after a specified period of time, the sensors re-detect the intruder's movement in the protected room. The control code infrared signals from the remote control unit 15 toggle the system from On Mode to Standby Time-On, where the system remains for a time sufficient to access intruder deterrent device 1 and toggle the system off when remote control device 15 is approached. work standby mode. If the control code magnetic signal receiver 35 is installed prior to the entrance of the room, the system does not need to be switched from standby to delayed standby. The output of the sensors 2 disables the system intruder deterrent device 1 without delay if it detects an intrusion. In this case the transmitter 7 of the control code magnetic signal receiver is switched off. The control code infra-red signal receiver 6 no longer needs to be activated. The system is serviced by audible signals: when the system is switched from off mode to delayed mode, a high-pitched signal is given, the duration of the cell being equal to the set time of this mode. The nature of this signal changes if the protected room enters or remains in the protected room for a longer period of time. Audible Alarm Accompanying Alarms: The digital indicator light alarms in their duration about the on mode of operation indicate the relative amount of deterrents used by the power source 8 indicated by the LED 9, which also indicates the system's transition to the on mode. An additional remote deterrent device 26 is used when the system is installed in larger rooms. To ensure the reliable operation of this device, the power supply wires connecting the device to the device provide power signals from the processor 5 to charge the backup power supply, and in the event of an intrusion, the same wires feed a series of modulated pulses equal to the idle time 26 automatically enters the deterrent mode if communication wires are low. If those wires come at a high level, the device automatically switches to operating mode with device 1. In the event that system sensors 2 have transmitted intrusion signals, an additional remote deterrent 26 triggers deterrents in addition to a separate command from the processor 5 when cutting the connecting wires. . The wiring is signaled by the signal loudspeaker 13 and the LED 30 stops blinking.
