Description

The invention relates to the field of information technology for alerting the public about emergencies in emergencies in hard-to-reach areas, about the current situation at the moment and transferring to the population the requirements and instructions from the civil defense services.

There are well-known outdoor advertising systems designed for advertising and informational support for sporting events - this is a “video display” with support for 65,536 colors and a frame rate of 30 frames per 1 from AD-ART ELEKTRONICS 3133 N. AD ART ROAD, P.O. BOX 8570 STOCKTON, CA 95208, (800) 350 - 7773, United States.

Lighting installations for image projection, visual effects during entertainment, laser shows were widely used. For example, a projection device (RU No. 2275664 C2, G03B 21/00, 2006), which is the closest prototype of the invention.

However, the disadvantages of these settings are the considerable time required to bring them from a transport position to a state of readiness for use, the lack of sound accompaniment of image broadcasting, the inability to work at low temperatures, and the transfer of information about monitoring the situation to control centers.

These shortcomings can be eliminated through the use of special mobile systems for informing and warning the population in the interests of ensuring life safety in everyday conditions and in emergency situations of peace and war.

A technically achievable result is an increase in the efficiency of warning the population about emergencies in hard-to-reach areas and in areas affected by flooding by means of prompt delivery to the place of use and ensuring the multifunctional operation of the mobile complex.

This is achieved due to the fact that in the mobile complex for informing and alerting people in hard-to-reach areas, consisting of a vehicle and a full-color LED screen, an amphibious vehicle (ATS) on an air cushion with a built-in video screen and sound devices is used as a vehicle being information carriers, a control device, a screen protection device, a power supply system, sources of video and audio information, as well as fully equipped with a system for monitoring and controlling the operation of the video screen through the control unit, a computer and a high-speed digital channel and containing an additional computer for the preparation of information clips, digital, sound, text and video information, while the method of transmitting (bringing) information for its visual and audio (auditory) perception is based on the installation on a vehicle (hovercraft) of an information carrier that forms a systematic video and sound series, while the range of distances arantirovannogo reception and recognition of information may vary depending on the number of people present, and local climatic conditions.

In FIG. 1 shows a General view of a mobile complex mounted on an amphibious vehicle (ATS), in FIG. 2 shows a diagram of a mobile complex in plan; FIG. 3 is a diagram of a comfortable passenger cabin for evacuated during emergency response, FIG. 4 - layout of a lifting-propulsion system, in FIG. 5 - embodiment of vibration isolators 18 and 19 of the lower suspension of the cabin, made in the form of coil springs with a built-in damper, which improves the comfort of the cabin.

A mobile complex for informing and alerting people in flood-affected areas is mounted on a vehicle (Figs. 1 and 2), which uses an amphibious vehicle (ATS) with an air cushion with a video screen and sound devices built into it (not shown shown), which are information carriers, a control device, a screen protection device, a power supply system, sources of video and audio information. The mobile complex is equipped with a system for monitoring and controlling the operation of the video screen through the control unit, a computer and a high-speed digital channel and contains an additional computer for the preparation of information clips, digital, sound, text and video information.

An amphibious vehicle (ATS) on an air cushion for evacuating victims in emergency situations (Fig. 1 - Fig. 4) contains a bottom platform of the hull 1, buoyancy units 2, engine 3, fan 4, transmission 5, propeller 6 in the aerodynamic ring 7, air rudders 8, brake flaps 9, reactive compensation grid 10 located between the propeller and rudders, flexible enclosure of the pressure zone 11, safety belt 12.

The movement of the ATS on water and land is carried out on an air cushion using a lifting and propulsion system (Fig. 4), consisting of an air cooling engine 3, a fan 4, a propeller 6 and air rudders 8. An air cushion is created by blowing air 4 into the zone increased pressure limited by a flexible enclosure 11. Buoyancy, stability and safety of the ATS on water are ensured by a sealed enclosure 1 and buoyancy units 2, which are made in the form of two floats placed on the sides orpus 1. A flexible guard and a safety belt 12 are attached to the outer contour of the buoyancy units 2 on the removable brackets 12. To improve controllability and increase safety, the ATCs use brake flaps 9 controlled from the driver’s cab (Fig. 1), consisting of a set of flexible plates of variable section, guide knives rigidly fixed at the ends of the lower plates, brake spikes, elastically fixed at the ends of the upper plates with elastic elements, pneumatic cylinders actuating the brake flaps, and pneumatic corrugated chambers with flexible air hoses that actuate (exhaust) brake spikes (not shown in the drawing). When interacting with the surface of the earth, water, snow, ice, guide knives provide the necessary travel stability, prevent the vehicle from skidding on turns, slopes, and provide a turn in place. However, the braking effect of the guide knives, especially on ice and frozen soils, is insufficient. To enhance the braking effect, at the command of the driver, the drive of the brake flaps and the drive of releasing the brake spikes are simultaneously actuated, which ensures the necessary exchange of vehicles on the course and effective braking. For better adaptability to the relief of the abutment surface and to increase their survivability, the brake flaps are spaced symmetrically in plan terms with respect to the longitudinal axis of the ATC at a distance “B” equal to 0.3-0.5 of the height of the airbag and are interconnected by an elastic spring (not shown in the drawing shown). The distance between the brake flaps is selected from the condition of laying in the center of the body of the flexible keel section of the air cushion (not shown in the drawing).

The propeller 6 is connected by transmission 5 to the shaft of the engine 3 and, for safety, is placed in a ring 7 having an aerodynamic cross-section in order to increase the efficiency of the propulsion device (screw). In the air stream in the area of the propeller to control the movement of the ATS in the horizontal plane, air rudders 8 are installed, which have several vertically arranged blades to increase efficiency. Between the propeller 6 and the air rudders 8 there are horizontal blades 10 of the jet grid deflecting the air flow behind the propeller upward and creating a reactive moment relative to the center of gravity of the ATC, directed in the opposite direction of the tilting moment of the screw.

The drive for controlling the position (angle of inclination) of the blades of the reactive lattice and, as a result, the leveling of the longitudinal roll of the reactive moment housing are kinematically connected with a contact roll sensor (not shown in the drawing) installed in the bow of the housing under the bottom. When lowering the bow of the ATC housing by an amount exceeding the permissible safety conditions for movements and touching the fifth foot of the roll sensor of the surface of water, snow or ice, a signal is automatically issued to increase the angle of inclination of the blades of the reactive grid, the reactive moment increases and the ATC case is leveled.

To reduce energy costs and increase the efficiency of an amphibious vehicle, especially at high speeds, the hull, buoyancy units and a flexible guard have streamlined aerodynamic contours in plan and longitudinal sections.

To increase the strength and reliability of the ATS, the support structure is additionally equipped with a spatial elastic-damping frame structure (Fig. 2), connecting the platform-bottom of the housing 1 and the buoyancy blocks 2, on which two elastic plates 13 are located, located on the sides of the housing 1, which are elastically-damped couplers 14, consisting of two rigid parts connected in the middle by a damping element (not shown in the drawing), are pivotally connected to the platform-bottom of the housing 1.

A comfortable passenger compartment for evacuated during emergency response (Fig. 3) is a metal die-welded frame 20, consisting of supporting profile structures (not shown in the drawing), inside of which there are packages of soundproofing elements 24, each of which includes layers of vibration damping material on a bitumen basis and at least one layer of porous sound-absorbing material and a perforated decorative panel, moreover, between the panel and the layer of porous sound-absorbing material, An air gap (not shown). Inside the cabin, piece sound absorbers are attached to the ceiling and walls (not shown in the drawing). The cabin frame 6 is connected to the supporting structures 15 of the vessel by means of a vibration isolation system consisting of an upper suspension, including at least two rubber vibration isolators 16 and 17 of the upper suspension of the cabin and at least two vibration isolators 18 and 19 of the lower suspension of the cabin, made in the form of cylindrical or conical coil springs. Inside the cabin there is a table 21, a chair 22 and a bed 23 for personnel serving the vessel, and the fastening of these items to the frame 20 of the cabin can be carried out rigidly or through vibration damping pads (not shown). The cabin is equipped with a suspended acoustic ceiling (not shown in the drawing).

Packages of sound insulation elements 24 can be made either solid or consisting of elements (not shown in the drawing) inscribed in the outline of the cabin frame 20 and consisting of a front with slotted perforation and a rear wall made of stainless steel or galvanized sheet with a thickness of 0.7 mm with a protective and decorative polymer coating of the Pural type with a thickness of 50 microns or Polyester with a thickness of 25 microns, or an aluminum sheet with a thickness of 1.0 mm and a coating thickness of 25 microns. In this case, the front and rear walls of the packages can be made of structural materials, with a layer of soft vibration-damping material, for example, VD-17 mastic or “Gerlen-D” type material applied on its surface from one or two sides, and the ratio between the cladding thickness and vibration-damping coating lies in the optimal range of values - 1: (2.5 ... 3.5).

The sound-absorbing material of the acoustic insulation elements is made in the form of a plate made of rockwool basalt mineral wool or URSA type mineral wool or P-75 basalt wool or glass wool lined with glass wool or foamed polymer, such as polyethylene or polypropylene, moreover, the sound-absorbing element over its entire surface is lined with an acoustically transparent material, for example, fiberglass type EZ-100 or polymer type "Poviden." Sound-absorbing material can also be made of rigid porous sound-absorbing material, such as foam aluminum or cermets, or metal foam, or a shell rock with a degree of porosity in the range of optimal values: 30 ... 45% (not shown in the drawing). Sound-absorbing material 6 can be made in the form of crumbs from solid vibration-damping materials, for example elastomer, polyurethane, or plastic compound such as Agate, Anti-Vibrate, Shvim, and the size of the fractions of the crumb lies in the optimal range of values: 0.3 ... 2, 5 mm (not shown in the drawing).

Conducted full-scale tests of the claimed amphibious vehicle on an air cushion showed good stability of the ATS on water and land, good maneuverability at high and low speeds, sufficient protection of the propeller.

The storage medium 26 (Fig. 1 and Fig. 5), made in the form of a video screen, is placed on an amphibious vehicle in a rectangular frame 25, the perimeter of which is made equidistant to the perimeter of the video screen and mounted on the PBX by attaching its lower part to one of the elastic plates 13 connected by elastically damped couplers 14 with the platform-bottom of the housing 1 and buoyancy units 2 on which these plates are rigidly fixed, and the rectangular frame 25 of the video screen is attached to the elastic plate with the upper part, opposite located in relation to the video screen by connecting with screeds 27 and 28, adjustable length.

The storage medium is delivered to crowded places. As the information carrier, a full-color video screen 26 (type AC 012SM.24) is used, manufactured using LED technology and equipped with a protective device in the form of an automatically lowering or rising sealed cover (not shown in the drawing). The screen protector allows you to protect the LED screen from external sources of pollution that occur during transportation and storage. The screen protection device can be structurally made in the form of a lowering curtain with its own electric drive. The control device is designed to control the operation of the video screen 26 through the control unit and the connected personal computer through a high-speed digital channel. Installation of an additional computer allows the preliminary preparation of information clips, text and other information coming from peripheral sources directly from the operator of the complex (not shown in the drawing). Computers connected to a common network have the ability to connect to an external information network using Wi-Fi, WiMAX, GPRS, 3G technologies or via satellite connection.

A mobile complex for informing and alerting people in flood-affected areas works as follows.

The amphibious vehicle is operated in the following way: the power plant is started, the air cushion and propeller are turned on, the ATS rises to its working height and movement begins on land or on water. In this case, the brake flaps, depending on traffic conditions, are either removed into the corresponding platform niche (not shown in the drawing), or used in the process of movement. The force of pressing the brake flaps on the supporting surface (earth, snow, water, ice) and their holding ability are regulated by the driver during movement by changing the force of pressing the control (brake pedal).

A comfortable passenger compartment works as follows.

Packages soundproofing elements 24 reduce the structural and reverberation components of noise. Polyurethane foam gaskets effectively dampen high-frequency air vibrations, the source of which is the sound pressure flow energy. Polyurethane foam is at the same time a reliable heat insulator due to its high porosity, insulated on both sides by a thin melted polyurethane foam film.

Decorative perforated wood-fiber board is a good damper. The transition of sound energy into thermal energy (dissipation, energy dissipation) occurs in the pores of the sound absorber, which are the Helmholtz resonator model, where energy losses occur due to friction of the mass of air in the resonator neck oscillating with the excitation frequency against the wall of the neck itself, which has the form branched network of pore sound absorbers. To prevent the eruption of a soft sound absorber, a fiberglass fabric, for example, type EZ-100, is located between the sound absorber and the perforated wall.

In an emergency, for example, if the air bag crashes, the supporting structure is a spatial elastic-damping frame structure (Fig. 2), connecting the platform-bottom of the housing 1 and the buoyancy blocks 2, on which two elastic plates 13 are connected rigidly, coupled by elastic-damped tie rods 14 with hull 1, will prevent damage to hull 1 and the comfortable passenger compartment (cabins or cabins) located in it for those evacuated during emergency response.

The storage medium 26, placed on a vehicle, is delivered to crowded places. Information transfer through the screen and loudspeaker can be carried out both at stops, and during the movement of the vehicle.

The choice of the place of transmission of information and the distance to the objects for obtaining information is carried out depending on local conditions and the presence of crowds. The transmission of information when the vehicle is moving is carried out continuously, regardless of local and climatic conditions. The reading range of video information depends on the characteristics of the screen and ranges from 6 to 100 m (12-300 m).

The ranges of perception of sound information and sirens depend on the power of loud-speaking devices and are:

for voice information - up to 60 m;

for sirens - up to 300 m.

Changing the range of perception of video and audio information depends on climatic and local conditions, as well as the time of day. Information is transmitted to the video screen (video screen control) and sound devices by the operator from the ship’s premises, where the input sources, control devices, converting and transmitting data are installed.

Used LED (LED-Light Emission Diode - from the English light-emitting diode) screen allows you to display a television image, computer graphics, animation, photographs, etc. In this case, almost any video device can serve as a video signal source - a video or TV camera, VCR, computer , DVD player, conventional or satellite TV antenna with tuner.

The information and warning device allows you to promptly alert the population in places of mass stay of people in various crisis situations; during the emergence of threats of a military, technological and natural nature; to inform the population on issues of civil defense and protection against emergencies of various nature, as well as to carry out various video and alphanumeric information of high brightness, which ensures its effective use at any time of the day.

A possible embodiment of the vibration isolators 18 and 19 of the lower suspension of the cabin, made in the form of coil springs with a built-in damper (Fig. 5).

A cylindrical coil spring with a built-in damper comprises a cylindrical coil spring consisting of two parts 31 and 32 with opposite ends 34 and 33 of the respective turns of these springs. Support rings 29 and 30 are made on the support turns of the spring for strong and reliable fixation of the ends of the springs during their operation.

The first part of the coil spring 33 is made with coils of rectangular (or square) section with rounded edges, and the second part 32 of the spring is hollow, for example of circular cross section, while the opposite direction 34 of the first spring part is placed in the cavity of the opposite direction second spring part with the end 33, while its second end, mounted on the support ring 30, is sealed, for example, using a screw plug (not shown).

In the cavity of the second spring part 32, made of a hollow circular cross section, formed on four sides, relative to the rectangular cross section of the first spring part 31, the gaps 35 of the segment profile in a section perpendicular to the axis of the contacting parts 31 and 32 of the spring.

The first part 31 of the coil spring, made with turns of rectangular (or square) section with rounded edges, covers the tube 26 of a damping material, such as polyurethane. The gaps in the first part 31 of a coil spring made with coils of rectangular cross section, which is covered by a tube 26 of damping material, are filled with crumbs of friction material (not shown in the drawing).

A variant is possible when the gaps in the first part of a coil spring made with coils of rectangular cross section, which are covered by a tube of damping material, are filled with crumbs of friction material made of a composition comprising the following components, in their ratio, in wt. %: a mixture of rezol and novolac phenol-formaldehyde resins in the ratio - 1: (0.2 ÷ 1.0), in the amount of 28 ÷ 34%; fibrous mineral filler containing glass roving or a mixture of glass roving and basalt fiber in the ratio - 1: (0.1-1.0), in the amount of 12 ÷ 19%: graphite in the amount of 7 ÷ 18%; a friction modifier containing carbon black in the form of a mixture with kaolin and silicon dioxide in an amount of 7 ÷ 15%; barite concentrate in an amount of 20 ÷ 35%; talc in the amount of 1.5 ÷ 3.0%.

Combined spring with integrated damper works as follows.

The spring stiffness is adjusted by shortening or lengthening the spring height. When the support rings 29 and 30 rotate, the coil of the spring moves relative to each other in mutually opposite directions relative to the longitudinal axis of the spring, i.e. screwed in or out. In the first case (when screwing in), the stiffness of the spring increases, and in the second case (when unscrewing) it decreases, which makes it easier to adjust the stiffness of the spring.

Thus, due to its selective properties, the spring provides effective spatial vibration isolation of the cabin in all six directions of vibrations (along the three axes X. U, Z and rotary vibrations around these axes) with vibration damping at resonance and under various operating conditions, which can significantly increase the comfort of the cabin .
