Description

Technical field

The invention relates to security systems and can be used to protect various objects. For example, passenger aircraft, nuclear power plants, oil and gas pipelines, storage facilities, tankers, warehouses, banks, tunnels, subways, government agencies, private homes, computers and other facilities.

State of the art

Devices are known in which an electric current is used to deter a criminal from an object, by which, by means of electrodes mounted in a guarded object and appropriately arranged, electrodes are applied to a criminal, causing electric shock (US Patent No. 4821017, class B60R 15/00, 1989).

The advantages of these devices: effective psychological impact on the offender, high speed, lack of pollution of the surrounding space with gas or liquid.

Disadvantages: design complexity due to the need to install contact electrodes in the form of wires, metal grids, etc. In addition, it is necessary to use high voltage to influence the criminal, since his body is insulated with clothes, and his hands can be insulated with gloves. It is impossible to influence the criminal at a distance, the contact method is contact.

A device is known for scaring offenders from objects (RF patent No. 2084018, class 6 G08B 15/00, publ. 10.07.97).

It contains an electronic signaling device controlling a microwave generator with an antenna.

The advantage of the device is the ability to effectively protect the entire volume of the room or part of it through the formation of a powerful microwave field, effectively scaring offenders.

The disadvantages of the device are poor selectivity of the microwave barrier, the inability to quickly change the local exposure zone throughout the space of the protected object.

A device is described in the patent of the Russian Federation No. 47823, publ. September 10, 2005, Cl. B60R 25/00, which is a user identification system containing nodes of a friend or foe system - an electronic alarm system installed on a guarded object (electronic alarm system) and a mobile device with an independent power source (user transponder) located in another area of space ) These nodes perform the recognition function "friend or foe" for a certain time after turning on the system through wireless exchange between the said nodes of the encoded signals with the set control parameters for their comparison and making appropriate judgments.

The disadvantages of the system are the possibility of remote, unauthorized copying of codes of a friend or foe system and their subsequent use, for example, by criminal elements involved in car theft.

Disclosure of invention

The problem solved by the invention is to increase the effectiveness of counteraction to criminals.

The technical result that can be obtained by carrying out the invention is highly selective protection of the degree of impact on the offender and an increase in the speed of detection of the offender and his location.

An additional technical result that can be obtained is the protection of an object from harmful or dangerous living objects. For example, from rodents, insects, predatory animals, etc.

To solve the problem with the achievement of the specified technical solution in the known device protection device containing an electronic alarm device with at least one sensor connected to it and a generator with a radiator, while the output of the electronic alarm device is connected to the generator start input, the security the alarm is performed with the ability to automatically recognize a friend or foe for a certain time after turning on at least one alarm sensor by wireless exchange of encoded signals between nodes of a friend or foe system located in an electronic alarm device and nodes of a friend or foe system, removed to another area of space in the form of at least one mobile friend or foe with an independent power source. According to the invention, the security alarm is performed in the form of a combination of two friend or foe systems, differing in code or physical nature of the generated friend or foe signals.

This advantage, as well as the features of the present invention will become apparent during the subsequent consideration of the following examples and embodiments of the invention with reference to the accompanying drawings.

Brief Description of the Drawings

Figure 1 shows a functional diagram of a device according to the invention; figure 2 is a variant of the protection device of the aircraft.

The best embodiment of the invention

The object protection device (FIG. 1) contains an electronic alarm device 1, a generator 2, an emitter 3, a power supply 4, a sensor 5, a switch 6. The output of the electronic device 1 is connected to the start input of the generator 2.

The device also contains a stationary emitter 7 of the request signal and a stationary receiving element 8 of the response signal of the friend-or-foe system, connected with the output and input of the friend-and-foe system, which is part of the electronic alarm device 1. And also at least one mobile device 9 of the "friend or foe" system.

The mobile device 9 of the friend or foe system includes a transceiver 10 connected to a transceiver antenna 11 and a mobile power source 12.

The shape and design of the mobile device 9 "friend or foe" can be varied. Such a device can be made in the form of a watch, ring, necklace, mobile phone, keychain, fountain pen, watch rim, tablet, headgear, police badge, etc.

According to the invention, the electronic device 1 is configured to automatically recognize "friend or foe" through the wireless exchange of information between stationary and mobile nodes of the "friend or foe" system. These nodes are in various places.

Sources 4, 12 may be of any known type.

The device operates as follows.

Using the switch 6, the electronic device 1, which can be used as any known alarm device, is put into standby mode.

The switch 6 can be implemented in any known form. For example, together with an alarm delay timer in the form of a remote control, an interactive control system, etc.

While in standby mode, the electronic device 1 consumes little energy, and the generator 2 is turned off. There is no radiation inside the guarded object.

When approaching a protected room or when an unauthorized person enters a room, a sensor 5 detects the appearance of corresponding signals.

The sensor 5 can be made in the form of any known sensor 5 or a combination thereof, for example, a push-button switch, a sensor that records changes in the structure of an electric, magnetic, electromagnetic, ultrasonic field, a video camera, an infrared sensor, etc. By means of the sensor 5, the electronic device 1 (transmitter) is activated and at its output, intended for connection to the emitter 7 of the friend-or-foe detection device, a request signal is generated.

The request signal may be implemented in any known form. For example, in the form of an encoded radio signal or infrared radiation. For example, it is similar to a signal generated manually from the TV remote control or to disarm and arm a car alarm.

Through the emitter 7, the request signal is distributed in the desired area inside the protected object or near the protected object. This radiation can be carried out in all directions or only in a certain local area in accordance with the radiation pattern of the emitter 7 and the place of its installation.

For example, radiation can be generated mainly in the area of the driver’s car seat, in front of the driver’s door of the car, in the lobby of the building, near the safe, near the piping for pumping gas, oil, water, near the poles of power lines, etc.

If the registered object or subject has with it a corresponding mobile device 9 of the friend or foe system, which is in the on state by the switch 13 (in some embodiments, the switch 13 may be absent), then by the transmitting node of the mobile device 9 in response to the request signal to In automatic mode, a response signal is quickly generated. This signal is received by means of a stationary receiving device 8 and is processed (decrypted). As a result of such processing, a decision is made in a short time. His or her alien.

If this is “your”, then the output of the electronic device 1, designed to start the operation of the generator 2, does not generate a signal to start the generator 2 to work and scare away or damage the detected object or subject.

While the object is in the protected area and somehow manifests itself, initiating the activation of the sensor or sensors 5, the further algorithm of the system may have a variety of options.

For example, after confirming that it is “your own”, the sensor 5 is turned off for a while, for example for 15-30 seconds. Or, for each subsequent operation of the sensor 5, the next friend-or-foe request is immediately sent. Moreover, the code of such a request can be constant or variable, for example, gradually increasing in the first category by one, in the second category by two, in the third by three, etc. And so on, until the source initiating the inclusion of the sensor 5 is removed from the protected object or transferred to another area of the protected object, where other sensors 5 will react to it.

If an incorrect code is received as a result of processing and decoding the received signal, then a decision is made that it is “alien”, and a signal is generated at the output of the electronic device 1, which includes the generator 2 in operation.

This may also include additional signal generators. For example, a shaper of a phone call to the police, sound or light alarm, information messages for a detected object, etc.

Generator 2 can be made emitting microwave signals, sound, infrasound, ultrasonic waves.

As the generator 2 and the emitter 3, you can use the "generator of mechanical signals" - an engine or mover, kinematically connected with some mechanical device. For example, a trap, a controlled barrier, a protruding obstacle, controlled doors, gates, etc.

As a generator 2 and emitter 3, you can use an electric discharger (capacitor), a laser or any other known signal generator 2 and the corresponding emitter 3, which is able to scare away, seize a criminal, an animal or disable a durable mechanical device that has invaded a guarded object. For example, a reconnaissance robot, a terrorist robot, a car or other foreign object.

To counter extremists in transport, it is possible to install emitters 3 in the ceiling and in the floor in the aisle between the seats so that the entire aisle between the seats becomes broken into small zones. For example, as shown in FIG. 2.

In each local security zone, one or several generators 2 with emitters 3 (for example, lasers), radiation absorbers 14, as well as, for example, sensors 5 made in the form of optocouplers 15, and a sensor made in the form of a video camera 16 can be installed.

As an electronic security device 1, you can use a computer with appropriate software.

By dividing the entire space of the aisles, for example, in the aircraft cabin into small zones, the impact on people in the aisle 17 who have a friend or foe system (stewardesses, pilots, marshals) and do not have such a system of people 18 - extremists, hooligans can be produced selectively and very dynamically.

For automatic on-line analysis of the current situation (signals coming from sensors 5) and “friend or foe” request and response signals, you can use a computer and an appropriate program that allows, for example, to cyclically, in accordance with the hazard level chosen by the pilot, form the process of neutralizing people in areas where there are no signals of the "friend or foe" system.

Using such a system, in a split second you can quickly analyze the locations of extremists and neutralize them without harming people with a friend or foe system and all other passengers who sit in their places and do not show acts of aggression that are not safe for flight airplane ground.

The main advantages of such a system are the absence of negative consequences that may occur when using traditional technical means of protecting aircraft with firearms, as well as the exclusion of the possibility of hitting passengers with crazy marshals 'bullets or criminals' weapons.

In order for extremists not to take over the friend or foe system, mobile devices 9 of the system can be made in the form of simple, small-sized devices such as pills or tablets with a short duration.

Devices 9 can be made in the form of disposable devices. Their activation and programming of the "friend or foe" code can be carried out before each new flight of the aircraft.

The durable plastic case of the device 9 protects the user from side effects and is removed from the human body in a natural way, for example, like a watermelon seed.

The proposed device can be used to protect almost all known vehicles (cars, planes, boats, yachts, motorcycles).

For example, a car security system may have a single-level or two-level security system.

The first level security system can send a request signal "friend or foe" when approaching a person’s car or touching the driver’s door handle.

The second system, which generates a request signal "friend or foe", for example, already with a different code and a different physical nature of the signals, can be installed inside the car.

This system can be activated by another sensor or sensors 5. For example, a penetration sensor or several sensors (opening a door, causing pressure on the seat, etc.). The coverage area of the "friend or foe" system of the internal security alarm can be very small - in the area of the driver's seat.

The combination of two such devices eliminates the possibility of intercepting the code even near the car and dramatically increases the protection of the car due to constantly updated codes during penetration into the car and during exit from it. At the same time, a driver who has a mobile device "friend or foe" does not need to press any buttons and climb into the pocket of his trousers or jacket behind a security key fob.

Using such a device makes the traditional ignition key unnecessary. In newly manufactured cars, it can be replaced with a simple electric button or an interactive (voice) car control system.

A car equipped with such a system is almost impossible to steal. Total search and selection of codes is impossible, because you need to know the two codes "internal" and "external". Due to the small amount of time allotted for the response of the requested signal, it is impossible to manage to transmit more, for example, just one code message. This time may be, for example, of the order of 0.001 sec. And after registering the incorrectly sent code, the car security system activates and, for example, begins to progressively increase the blocking time to re-enable the "friend or foe" system.

If the car was opened in a barbaric way, for example, by breaking a window or opening the door with a crowbar, then it will be impossible to get into the car in order to open the hood cover and try to start and drive off the car bypassing regular electrical circuits due to the effect of a powerful electric discharge high voltage or, for example, due to narrowly focused radiation of a microwave device in the area of the driver's seat and a blinding criminal of laser radiation.

The failure of a standard battery, for example, by punching its body with a metal pin through an opening in the front grille, will also not have an effect. A separate source or power sources can be used to power the burglar alarm, connected to the electric circuit of the car through decoupling diodes and disguised inside the car or other protected vehicle.

Such systems are effective for the protection of various buildings and premises. For example, for the protection of government agencies, strategically important facilities, summer residences, private houses, greenhouses, farms for power transmission poles, etc.

For example, if criminal elements or dangerous animals got into the guarded premises, then there is no need to call the police and engage in combat with uninvited guests until the police arrive. The system itself will carry out their selective search and neutralization.

For example, during the invasion of criminal elements in the bank's vault, the impact on criminals will be selective - only in those places where unauthorized persons are not supposed to be. At the same time, bank employees and visitors will not suffer. There is no need to shoot at criminals, endangering the lives of others.

Employees of companies engaged in the maintenance of such guarded facilities should have mobile devices 9 of the "friend or foe" system, for example, structurally located in the helmet of a working electrician.

It is important that the mobile devices 9 of a friend or foe system at the right time are on the employees of the protected object or on its owner.

Protection of oil pipelines and gas pipelines can be carried out using 2 generators and 3 emitters of microwave emitters, lasers or electroshock devices as generators.

The design of such a pipe is, for example, multilayer in the form of a main steel body, anti-corrosion, dielectric coating, electrode system with sensors 5 and a power supply line of the security system and an external dielectric protective layer.

When you touch such a pipe with your hand or body, or when significant pressure appears on the pipe surface, sounds characteristic of drilling the pipe, the corresponding local sensors 5 are turned on, and in a small area of protection near the location of this sensor, an electric shock device is turned on.

High-voltage current flows mainly along the path of least resistance - through an attacker touching the pipe and the ground on which it stands, and partially through the internal insulation resistance of the pipe.

The stun device can be equipped with a protection system.

Laser supports, microwave transmitters, local security devices, distribution transformers, powerful loudspeakers or sirens that repel criminals from an object near an activated sensor 5 can be installed in the pipeline supports, as well as radio alarm emitters and pipeline malfunction sensors (strong vibration sensors during explosion, sensors of the temperature of the pipeline body, its integrity, etc.).

The mobile device 9 may have a power control system and in time to signal to the user about the need to recharge it.

Most preferably, the device 9 is produced in the form of widespread small-sized, portable electronic devices: electronic watches, mobile phones. This additionally increases the secrecy of the security system and expands its capabilities due, for example, to promptly automatically call the police when the security alarm is triggered and broadcast audio and visual information from the crime scene.

In an embodiment, a stationary electronic security device 1 can be configured to generate sound signals explaining to the criminal the most optimal patterns of his behavior in order to reduce the degree of negative consequences for him. For example, that he should stay motionless until he is arrested, or scare the criminal, explaining to him that he has already been discovered and is already in the role of the potential criminal whom the security service is looking for.

When developing a unified protocol for the exchange of "friend or foe" data in household (home or car) security systems intended for a wide range of users, mobile and stationary security devices can be manufactured by various manufacturers and have various functional capabilities. However, they can be fully compatible. For example, in one electronic wristwatch several devices 9 of the friend-or-foe system can be located - to protect various protected objects. For example, a private store, cars, safe, yacht, home, cottage, computer, etc.

Synchronization and start-up of such devices can be carried out by the user according to the instructions at the time of initial installation and start-up of the alarm system by entering the same initial request and response codes and, for example, the conversion code in each stationary alarm device 1 and in any number of mobile devices 9.

Industrial applicability

An object protection device can be used to protect various objects: computers, vehicles, nuclear power plants, oil and gas substations, highways, storages, government buildings and institutions, banking facilities, museums, warehouses, farms, summer cottages, tunnels, subways, military facilities.
