Description

The invention объектов Object protection complex based on a lighting device ʺ relates to directional beam emitting lighting equipment, and more particularly, to the field of optical means of preventing unauthorized access to protected objects and protecting objects from using weapons with visual-optical and optoelectronic guidance systems on them.

The use of floodlight lighting devices to protect objects (search and detection of persons trying to penetrate a protected object) is quite widespread. Such devices as mandatory elements contain a light source, a power supply unit of the source and an optical system for generating a radiation pattern, for example [1]. As the development and improvement of such devices, they also became entrusted with the tasks of interfering exposure (temporary dazzle) on the organs of vision of violators [2], as well as on optoelectronic devices operating both in the visible and infrared ranges of the spectrum [3 ... 6]. Such devices have found application to protect not only stationary objects, but they have also begun to be used to protect aircraft, ships and mobile ground objects. For this purpose, remotely controlled rotary mechanisms and remote control panels [3 ... 7] were introduced into the composition of the devices. To change the angular divergence of the emitted flux in these devices, various light converters are used, for example, in the form of a mechanism for shifting the emitting lamp relative to the focus of the specular reflector [3, 4].

Known devices can operate in continuous mode or in a pulsed mode. When operating in pulsed mode, the frequency of modulation of the emitted light flux is selected based on the need to ensure maximum interference effect on the human senses and optoelectronic weapon control systems [8].

The energy level of the emitted light flux is chosen so that in the working range of the device application distances, along with ensuring the required level of interference, the possibility of irreversible damage to the organs of vision of people is excluded.

A device "Spotlight" [9], adopted as a prototype. The main distinguishing features of this prototype are:

- the implementation of the source of optical radiation from at least two xenon lamps installed in parallel;

- the use of a light shaper in the form of optical wedges;

- the use of a liquid cooling device in the form of a consecutive coverage of radiating lamps with temperature sensors;

- equipping the emitter with a rotary device with azimuthal and elevation electric drives with end angle sensors and switches.

The main advantages of the prototype, in comparison with other known devices, are higher reliability due to the use of several emitting lamps instead of one, as well as lower weight and size characteristics due to the use of a liquid cooling system using polymethylsiloxane as a heat carrier.

Along with the noted advantages, both the prototype and other known devices have a number of disadvantages. In particular:

In known devices, a necessary condition for pointing the emitter to the target is to enable the operator to visually observe the target and the spatial position of the light flux emitted by the device. The device control panel is installed permanently in the control center of the protected object, which can be an office building, ship cabin or other command post, having, if possible, the maximum viewing area of space by the control operator. The emitter of the device, mounted on a remotely controlled rotary mechanism, is located outside in places that provide maximum working sectors of target irradiation. The operator’s viewing areas of the space and the target irradiation sector by the emitter may not coincide for a number of reasons, for example, the configuration of the protected object, the presence of shading zones, significant separation between the control point and the location of the emitter, etc. This circumstance makes it difficult for the operator to remotely aim the device and limits the possibility of using the device in those sectors where the working sector of the emitter and the operator’s field of view do not match.

Another disadvantage of the known devices is that in their composition there are no means of determining the distance to the suppressed object. As a result of this, when using them, the device operator does not have the information to select the optimal values of the angular divergence and the radiated power of the light flux, providing, on the one hand, the necessary level of irradiation in the plane of the object, on the other hand, the maximum size of the irradiated zone.

The constructions of all known protection devices of protected objects are designed for the autonomous use of these devices, therefore, they do not provide for their connections with any external control systems, for example, with an automated control system for the facility’s protection means. If it is necessary to turn on the devices in one of the operating modes in accordance with with a general plan for protecting the object, or turning them off, including for the blackout of the protected object, for pointing the emitter in a given direction, changing angularly the divergence of the emitted light flux all the necessary commands operators, servicers, on oral instructions from superiors performed manually using the controls located on the control panel. Such an organization of device management requires the mandatory presence of a special operator, significant time spent on manual input of the necessary commands and does not exclude the possibility of erroneous operator actions.

The use of control panels as part of known devices is provided only for turning them on and off, controlling the rotary mechanism, transferring the devices to one of two operating modes - continuous or pulsed interfering radiation, changing the angular divergence of the emitted light flux. At the same time, the presence in the device structure of powerful directional optical emitters capable of operating in continuous and pulsed modes would allow the device to be used as light-signaling means, which would significantly expand their field of application, for example, in ship conditions. However, the composition of the known object protection devices and their control panels lacks radiation switching organs by the operator in the dot-dash mode. The control panels also lack any display elements, indicating the operating modes of the devices and the execution of incoming control commands.

In the case of using a single emitting lamp as part of the device, its operability is quite simply controlled by visual observation of the presence or absence of a glow at the emitter's output. If several emitting lamps are used in the emitter, this method of monitoring their operability is unsuitable, since if not all emitting lamps fail, a glow at the emitter’s output will be observed. As part of the known devices there are no structural elements designed to monitor and display the state of health of the emitting lamps, accounting for the operating time of the device.

A significant disadvantage of the prototype, affecting its reliability, is the fact that the liquid cooling system is made in the form of a consecutive pipeline for all emitting lamps. As a result, a malfunction in the operation of the cooling circuit of any of the lamps (for example, depressurization, overheating, clogging) leads to failure of the entire cooling system, i.e. all lamps, and therefore the device itself.

The present invention allows to increase the efficiency of use of the optical radiation device, expand the range of conditions for its use and the list of tasks solved by the device, increase its reliability, quality control performance, improve operational capabilities.

To achieve the technical result, the claimed facility protection system based on a lighting device, in addition to an emitter of several gas discharge lamps arranged in parallel and placed in a sealed enclosure with a liquid cooling system and a light shaper mounted on a rotary device, also contains such specified products as a control panel for remote control of the rotary device, a DVR (television or thermal imaging camera) and a laser emit spruce mounted on a rotary device and oriented in parallel with radiating lamps. In this case, the light shaper is made in the form of a zoom lens with a remotely controlled mechanism for changing the focal length, and the control panel is additionally equipped with bodies for monitoring the state of the device’s operability, controlling the operation of an incoherent emitter in light-signal mode, as well as the operation of a laser emitter and a television / thermal imaging camera, a video monitor and an information-command channel communication with the automated system of object protection. In addition, the remotely controlled rotary device is equipped with angle sensors in the horizontal and vertical planes

Salient features of the claimed complex of protection against the prototype and other known devices for this purpose are:

1. The presence of a DVR (television and / or thermal imaging camera), oriented parallel to the direction of radiation of discharge lamps. As a result, the device control operator has the opportunity at any time of the day to observe on the monitor screen of the control panel the suppressed object and the position relative to it of the spot of the light flux emitted by the device, even in cases where the working sector of the emitter and the operator's field of view do not match.

2. The presence of a laser emitter oriented parallel to the direction of radiation of the discharge lamps. In this case, the laser radiation can be used as a “pointer” for pointing the emitter to the target, as well as for creating interference in the daytime with optoelectronic devices operating in the visible and near infrared spectral ranges. In addition, the laser emitter, in the presence of a photodetector, can be used to measure the distance to the irradiated object.

3. The use of a zoom lens (zoom lens) as a light shaper, which, unlike a light shaper in the form of optical wedges, allows you to smoothly change the divergence of the emitted light flux depending on the size of the area to be irradiated.

4. The use of a liquid cooling system for gas-discharge lamps is not in the form of a consecutive coverage pipeline for all emitting lamps, but in the form of separate cooling circuits for each lamp. As a result, a malfunction in the operation of the cooling circuit of one of the lamps does not lead to failure of the device as a whole.

5. The use of structural elements in the control panel that provide the panorama, the observed television and / or thermal imaging camera (monitor), the control and management bodies for the television and / or thermal imaging camera and laser, the switch of gas discharge lamps in the "dot-dash" mode (light-signal mode), indicators of serviceability of gas-discharge lamps in the radiation mode (the presence of an acceptable current level in the lamp circuits), the time counter of the device in the radiation mode to control and the expenditure of the resource of the device. The presence of these elements allows the operator to remotely point the emitter to suppressed objects that are outside its visibility range, use the emitter in the light-signal mode, monitor the operability of the main elements of the complex, and keep track of operating time in the radiation mode.

6. The presence of channels of electrical interface with the central point of protection of the object (its ACS) and the angle sensors of the remotely controlled rotary device in horizontal and vertical planes. The presence of these elements allows you to broadcast to the central point of protection a visual image of the irradiated object and its angular coordinates, to receive control commands from the central point of protection, to guide the emitter in a given direction in angular coordinates.

Thus, the patented protection package is a product containing several specified products designed to perform interrelated operational functions.

The illustration shows a block diagram of a variant of the complex.

The complex contains a radiator 1, a control panel 2 and a power supply 10. The emitter 1 consists of a remotely controlled rotary device 3 with angle sensors in the horizontal and vertical planes 4. On the remote controlled rotary device 3 there is a block of gas-discharge emitting lamp modules 5 placed in a sealed casing (at least two modules, each of which has its own liquid cooling circuit), the radiation of which is output into space through a lens with a remotely adjustable focal length 6. Also, on a remotely controlled rotary device 3 there are a laser emitter 7 with a photodetector and a video recorder (television and / or thermal imaging camera) 8, oriented in the same direction as the module block of gas-discharge emitting lamps 5. All of the listed components of the emitter 1 have inputs and outputs for providing information and command communications with the control panel 2. The control panel 2 contains a monitor displaying video information, including a panorama, observed by the DVR 8, controls and command execution controls by a remotely controlled rotary device 3, lamp module 5, lens 6, laser 7, video recorder 8, indicators of the device’s health status and time counter for its operation in radiation mode. The control panel 2 has inputs and outputs for information-command communication with the emitter units and the hierarchically superior centralized control equipment for guarding the object 9, which is not part of the device.

The complex as a whole and its components work as follows. If an attempt to penetrate an object, an armed attack on it, a potential threat of security breach or for preventive purposes is detected, the complex is turned on and the emitter is guided in the direction of the actual or potential threat. Guidance can be carried out by the operator from the control panel 2 according to the observation by him using the DVR 8 of the panorama of the threatened area on the monitor of the console, or by the angular coordinates of the threatened area entered from the centralized security control equipment of the facility. For preliminary guidance of the emitter on the irradiated object, a laser 7 operating in the "pointer" mode can be used. It can also be used as a range finder for determining the distance to the irradiated object and assigning, based on these data, the angular divergence of the emitted interference signal, which is adjusted by changing the focal length of the lens 6. Moreover, the angular divergence of the light flux emitted in the interfering mode by the lamp module 5 should provide reliable “covering” of the threatened area with a light spot while ensuring a level safe for the organs of vision, but sufficient for their temporary blindness nya interference exposure at a distance of the location of the irradiated object.

If it is necessary to transmit light-signaling information, the operator directs the emitter to the desired object, setting the divergence of the light flux emitted by gas-discharge lamps at a level that ensures reliable irradiation of the object, and transmits information using the point-to-dash radiation switch located on the remote control management.

The above descriptions of the design of the claimed complex of protective equipment and its action (work) indicate the possibility of implementing this invention at the modern technical level and achieve the technical result for which it is intended. All components and components that make up the complex are individually known and mastered in serial production. In general, the inventive device allows to increase the efficiency of protection of protected objects.
