Description

The invention relates to a mobile automated complex intended primarily for monitoring by lighting the situation on land and / or long sea sections of the border and creating conditions for observing the terrain at ranges of up to 5 km in the dark when working from unprepared positions, as well as for organizing communications and exchange of information with automated systems of technical control (ACC) for the situation at the border.

The closest analogue was not found during the search.

The technical problem, which this proposal is aimed at, is to create a new generation of mobile radio-electronic searchlight complex with tactical and technical characteristics that allow the protection of long objects and territories, including borders, to facilitate rescue and other events, as well as the creation of conditions for working people on the ground in the absence of visibility, for example in the dark.

In addition, this complex is characterized by relatively small sizes and allows to ensure the reliability, energy efficiency and speed of all its systems, as well as the convenience of using them.

The problem is solved in the invention by the following set of features.

A mobile searchlight complex contains a vehicle made primarily in the form of an all-wheel drive truck, in the back of which a spotlight installation is fixed and associated secondary power supply and radio control units, as well as a gas-electric generator, are located in the vehicle’s cabin: crew commander’s workstation, including a system automated control unit; communication and data transmission system; Remote control and monitor for a thermal imaging night driving system, the camera of which is located in the bumper or on the radiator of the car.

The radio control unit is designed to receive signals from the remote control and convert these signals into commands by drives and a projector lamp, and the automated control system includes a laptop that allows you to receive information about the situation via the radio channel and display it on a digital map of the area, and an integrated satellite navigation system, which is an electronic cartographic system with an integrated electronic magnetic comp catfish and an external antenna located on the roof of the car cabin.

The communication and data transmission system is made in the form of a VHF radio station with a built-in radio modem for connecting digital information transmission equipment.

The projection unit is configured to form a narrow high-intensity light beam of variable width and to move it in space in two planes.

The floodlight installation is located on a support frame pivotally connected to the side supports for fixing the floodlight installation in the stowed position.

The car body is equipped with a frame and a removable awning.

The invention is illustrated by drawings, where in Fig.1 schematically shows the proposed complex (side view in operating position); figure 2 is the same from the end of the open body.

Mobile searchlight complex 1 is a combination of technical equipment located on the base chassis 2, made, for example, in the form of an all-wheel drive truck UAZ-23602, designed for movement on all types of roads and terrain. The aforementioned car is distinguished by an elongated wheelbase, a double cabin and a loading platform, as well as a higher level of comfort and improved technical and economic performance.

Using the proposed complex, the terrain is illuminated by a controlled narrow beam of high-intensity light, and this creates the conditions for observing with the naked eye or optical instruments (binoculars, etc.) objects in the absence of optical visibility (at night).

In addition, the complex is equipped with auxiliary devices that ensure safe movement on rough terrain at night (with the headlights turned off), topographic reference to the terrain, voice-activated radio communications, and radio channel reception of information about the situation from the customer’s ASTK with its display on the commander’s workstation monitor (RMK) using digital terrain maps.

The design of the main functionally completed parts of the complex is made according to the cabinet-block principle and consists of several constructs interconnected by a cable network.

The power basis of the design is a welded support frame 3 made of a steel rectangular profile and placed in the body 4 of the base chassis, on which the projection unit 5 is fixed. In addition, a gas-electric generator 6, a secondary power supply unit (cabinet) 7 are placed in the body 4 of the base chassis, and radio controls and side supports 8 for fixing the searchlight in the stowed position (figure 2).

Spotlight installation 5 is designed to form a narrow light beam of high intensity of variable width (from 3 to 8 degrees) with the possibility of moving the beam in space in two planes. As such an installation, a stationary XS 3000 floodlight with the following characteristics can be used: the range of the light beam - at least 10 km (1 lux) in normal atmospheric transparency; power - 3 kW; weight - 63 kg; brightness - 130,000 lumens. The time of continuous illumination of the spotlight (before automatic shutdown) is no more than 20 minutes.

Spotlight installation 5 structurally consists of:

- a molded case in which communication elements, elevation and azimuthal drives and a motion control unit are located. The housing of the rotary device contains two motors: one for vertical movement, the other for horizontal movement, and a heating element driven by a thermostatic relay. The heating element serves to ensure the operation of the searchlight at low ambient temperatures;

- a illuminator, which is a cylindrical casing, inside of which there is a lamp, a nickel-rhodium reflector, an anti-interference filter and a focusing engine for adjusting the light beam, and two rectangular forced air cooling units are placed on the casing outside. The body of the illuminator is made of aluminum, resistant to the influence of environmental factors, welded and protected by an organosilicon coating;

- attachment points of the illuminator to the housing and connecting cables.

The power supply system of the complex is built on a decentralized scheme that ensures the most economical use of electricity.

The power supply system includes:

- benzoelectric alternator;

- a secondary power supply unit with a voltage of 24 V - voltage converter type EX-100D / 1;

- rechargeable batteries of the base chassis;

- built-in rechargeable batteries of devices.

The main source of electricity for the equipment of the complex is a gas-electric generator 6. As such a generator, for example, a HONDA / EP 5000 СХ gas-electric station with a mass of 82 kg, a tank capacity of 25 l and a maximum generator power of 4.5 kW can be used.

Part of the equipment is powered by a voltage of 12 V, which is produced by the batteries of the base chassis. These consumers include either appliances and equipment that must operate on the go, or low-power consumers, such as:

- VHF radio station;

- satellite navigation system;

- night driving system.

Two consumers of electric power have built-in rechargeable batteries: an external remote radio control of a searchlight installation and an RMK laptop. The satellite navigation system (if necessary) can also be powered by built-in rechargeable batteries.

High-power consumers are connected to a secondary power supply unit generating 24 V DC voltage, the input of which is supplied with an alternating voltage of 220 V, 50 Hz, generated by a generator.

Block 7 provides the formation of the voltage necessary to power the projector 5, the radio control unit of the projector, which receives information from the remote control of the projector and converts the commands of this remote into control signals of the drives and lamp of the projector.

The radio control unit is designed to receive control signals from the remote control via radio channel, as well as converting control signals and generating commands to the searchlight. The unit is powered by 24 V DC from the secondary power supply unit and allows you to perform the following functions:

- azimuthal movement (PS / STB);

- moving in elevation (up / down);

- adjustment of the focal length (narrow / wide beam);

- inclusion of a lamp;

- turning on and off the main power supply.

The equipment of block 7 (Fig. 2) is located in a heated cabinet type RECW 156 AV. This unit, made in the form of a cabinet, is an anti-vandal design of increased strength. The central section of the cabinet is made of two solid sheets of metal connected to each other by a ceiling and a bottom without welds. Thus, neither cryogenic processing nor impacts lead to the destruction of welds and penetration into the cabinet.

The mechanical strength of the design of the searchlight installation in the stowed position (during transportation) is ensured by means of two supports 8 located on each side of the searchlight installation, each of which consists of two pairs of frames located at a distance from each other, each pair of which is pivotally connected to each other and with support frame 3.

Pads covered with elastic material (porous rubber) are fixed in the upper part of the end sections of the frames of the side supports 8, which serve to contact the illuminator of the spotlight in the stowed position while the side supports located on the sides of the searchlight are connected by a metal cable, which tension is regulated by a turnbuckle.

In order to reduce the impact on the searchlight of mechanical influences (shock, vibration) that occur during the movement of the base chassis, as well as during the operation of the generator (vibration), the searchlight and the generator are mounted on the frame using shock absorbers.

The complex is equipped with a removable awning 13, located on the frame 9 (figure 2), consisting of rungs and racks attached to the sides of the car body and allowing to protect the equipment located in it from the effects of rain and dust during movement and deployment of the complex.

Also, with partial folding of the tent, it allows you to limit the supply of the light beam of the searchlight in undesirable directions.

In addition, the tent serves to mask the complex in a stowed position. As such an awning, a regular removable awning of the UAZ-23602 car, made of a moisture-proof durable material, can be used.

The time of deployment of the complex and its transfer from the marching position to the working position by two calculation members does not exceed 10 minutes.

An automated workstation of the crew commander with an integrated satellite navigation system, which is an electronic cartographic system, which displays information about objects of interest for lighting that is received through the data channel, is formed in the cabin 10 of the base chassis of the car.

A communication and data transmission system is also located in the cockpit of the base chassis, which serves to provide voice communication between the crew and other subscribers, as well as for two-way exchange of digital information about the location of the complex and the location of objects of interest for lighting.

Inside the cab 10 of the base chassis the following equipment is placed:

- a processor unit (laptop) of the commander’s workplace, mounted with special brackets on the dashboard of the base chassis;

- VHF radio station with built-in radio modem for connecting digital information transmission equipment installed in the cassette for the car radio;

- monitor night driving system;

- remote remote control (removable);

- programmable channel module autonomous PKM-A;

- satellite navigation system, for example, a personal GPSMAP 76 / 76S navigator.

The aforementioned processor unit allows you to receive information on the situation on the border area via radio channel, display it on a digital map of the area and perform other operations. In order to increase the efficiency and effectiveness of aiming the spotlight beam at the objects selected by the operator, the equipment of the RMK complex is interfaced informationally with the automated systems of technical control of the Strip series.

The power supply of the equipment of the RMK is carried out from the batteries built into the laptop.

On the RMK screen are displayed:

- digital map of the area;

- location of ground moving targets taken by ACK sources for escort;

- targets forms (number, range, azimuth, course, speed);

- service graphic and text information.

The RMK control menu allows you to:

- change the scale of the image on the screen, including the map;

- measure the range, azimuth, latitude and longitude of the marks from the targets;

- determine the distance between two points;

- determine the time the moving target reaches the straight line segment on the map;

- determine the time of the meeting of moving targets;

- automatically detect and display radar visibility zones on the MSC.

The communication and data transmission system includes a VHF radio station, for example, such as VERTEX 3000 or ERICA - 201-026, with an integrated radio modem and a programmable channel module autonomous. The communication and data transmission system is intended for:

- organization of voice radio communication between the calculation of the complex and the customer units;

- organization of voice radio communication between the calculation of the complex and the customer’s units and two-way exchange of information between the RMK products and the complex of automation equipment of the ASTK “Strip” series according to special codograms of information exchange.

The proposed mobile searchlight complex is used for its intended purpose mainly at night and often from unprepared positions.

The screens of the monitors of the night-driving system and RMK can rotate relative to two axes in space and be fixed in a position convenient for operation.

The complex includes a night-driving thermal imaging system designed to ensure the safe movement of a vehicle with an off-road projection system in conditions of limited visibility (at night), including the possibility of hidden extension of the complex to a position at night without headlights. For this purpose, for example, the PathFindIR night driving system can be used, which is a small infrared thermal imaging camera built into the bumper of a car 11 or placed on its radiator 12, and a monitor in the driver's cab to display the situation on the road.

When placing the camera in the bumper of the car, the driver displays an image of the terrain (path) directly in front of him at a distance of about 200 meters and the situation to the right and left of the vehicle's course of movement.

The night driving system uses a miniature front-view thermal imaging camera, such as the Thermal-Eye G100, which is a barium-structure-titanium (BST) detector. The camera provides a clear image, is easily integrated into the vehicle’s structure, providing continuous operation, and has effective protection from exposure to light sources without the use of additional filters.

As a satellite navigation system, a 12-channel GPSMAP 76 / 76S personal navigator with an integrated electronic magnetic compass and an external antenna located on the roof of the car cabin is used. In one of the complex options, the satellite navigation system implements all the functions associated with the navigation of a moving object with the display of information on its own built-in monochrome display.

The power supply to the satellite navigation system is provided by the vehicle’s on-board network and built-in batteries, which allows the use of the GPSMAP 76 / 76S receiver both at the position (in the stationary position of the complex) and in motion.

In the cabin of the base chassis there is also a remote remote control of the projector, allowing you to control the modes of its operation both from the cabin of the base chassis and from anywhere outside the vehicle from a distance of 200 meters.

The complex works as follows.

Before deploying the complex, if possible, a relatively flat horizontal platform is chosen, which is designed to provide convenience in aiming the spotlight beam at the target. Then, partially or completely, the awning 13 is removed from the car body. In case of heavy rain and snow, the awning is folded down only to the middle of the body. Open the rear side of the car body and rise into the body. Using the rotation of the lanyards, weaken the stretch marks of the front and rear side supports 8 of the searchlight. Tilt the mechanical support of the searchlight to the side, leaning them against the sides of the car. Run the generator 6.

Then turn on the remote control, which leads to power on the spotlight 5 and the control unit, while the voltage is not supplied to the lamp. After a radio link has been established between the remote control and the radio control unit, the light comes on. Adjust the beam width. At the smallest beam width (3 degrees), the lamp energy is concentrated in a smaller solid angle and the range of the beam increases. Along with this, the level of illumination in the area created by the spotlight beam also increases. As the beam width increases, its delivery range decreases, but the area of illumination on the ground increases.

After adjusting the power, the electric lamps regulate the speed of the engine of horizontal rotation of the searchlight using a potentiometer located on the radio control unit in the block (cabinet) 7.

At small values of the horizontal rotation speed of the searchlight, the time of pointing the searchlight to a given direction in space increases, but the accuracy of pointing increases due to the decrease in the fluctuations of the searchlight when it is stopped.

At high speeds, the guidance time decreases, however, due to the overshoot effect, several (2-3) oscillations of the searchlight in the horizontal plane arise, which makes it difficult to accurately point the beam at the object.

The movement of the beam in space has limitations: in the vertical plane, the beam can be controlled within an angle of ± 25 degrees from the horizon, and in the horizontal plane ± 170 degrees from the zero (stowed) position.

In a communication and data transmission system, the operator has the ability to work only with a VHF radio station.

When the PKM-A module is installed in the complex, it is constantly connected to the power supply circuits, operates in automatic mode and does not require operator intervention. The radio station can work both in the static position of the complex and on the go.

After turning on the power, an image of the terrain immediately in front of the car and on the shoulders to the left and right of the direction of movement of the car will be displayed on the monitor screen in front of the driver.

A night vision system can also help in fog if it is not dense enough.

In conditions of lowered (negative) ambient temperatures, the spotlight heater turns on automatically when the power is turned on to block 7.

Switching off and curtailing the product is carried out in the following sequence:

- by entering the “Mode” submenu, correctly exit the RMK software and turn off the power to the laptop;

- press the latch of the monitor screen, turn it counterclockwise and lay it on the laptop case with the screen down, snap the monitor in the stowed position;

- turn off the power switch of the night driving system;

- turn off the power of the GPS-receiver and lower its body vertically down, fixing it in the holder;

- turn off the radio station;

- using the buttons of the remote control to set the spotlight to zero position horizontally and vertically;

- turn off the spotlight;

- turn off the AC switch / fuse;

- having opened the door of the power and control cabinet, put the differential current circuit breaker in the lower position;

- set the engine switch and fuel cock to the “OFF” position;

- after turning off the complex equipment, raise the mechanical side supports of the searchlight to a position in which the pads (base plates) fit snugly against the body of the searchlight;

- connect cables with lanyards;

- turn the lanyards to pull the cables to the position at which the spotlight is securely fixed;

- close the rear side of the car;

- stretch and fasten the awning of the car on the frame and on the sides of the body.

After that, the complex is in a stowed position and is ready to move.
