Abstract

The invention relates to search and rescue systems intended for providing prompt assistance to persons who are in life-threatening situations. A search and rescue system includes: a base object equipped with a receiver/direction-finding device and an omnidirectional antenna for receiving an emergency signal from a person in distress; a life-saving flotation means having a receiver/direction-finding device; and also a compact radio transceiver secured to a person and linked via a radio channel to the omnidirectional antenna and receiver/direction-finding devices of the base object and the life-saving flotation means. The life-saving floatation-means is a robotic floatation means equipped with an engine, a transceiver and an automatic control system. The base object is additionally equipped with perimeter monitoring means, a device for releasing a lock and automatically ejecting the flotation means, a transceiver, and a command device which, upon receiving a signal indicating that the perimeter has been crossed and/or a signal from a radio identifier of a person in distress, controls release of the lock and the automatic ejection of the robotic life-saving flotation means. The possibility of instantaneous rescue of persons falling from base objects is achieved.

Description

Search and rescue system.

The search and rescue system is designed to provide operational assistance to people who find themselves in life-threatening conditions. This system can be used in search and rescue operations, for example, at sea.

A marine rescue system and a method of its application are known, comprising a life jacket with a radio transmitter on a person in distress, a lifeboat (boat) with a radio receiver that is connected via GPS to a radio receiver of a life jacket (Application R 1020160036714), which begins to send distress signals after a person gets in in a life jacket into the water. The radio receiver of the rescue craft is connected to a device that ensures its movement upon receipt of distress signals, as well as a navigation system that provides the movement of the rescue vehicle to a person in distress in a life jacket, whose radio transmitter continues to send distress signals.

The disadvantage of the analogue is the connection between the rescue craft and those being saved using the GPS global geo-positioning system, since the speed and accuracy of the system depends on the current situation with the presence of a sufficiently stable and high-speed signal from a sufficient number of satellites in a particular place in the world's oceans and, as a result, can always provide sufficient speed and accuracy of the rescue operation.

A search and rescue system is also known (Application for the invention of the Russian Federation N ° 93007485), containing the base craft, on which there is a ship radio with an omnidirectional antenna, mounted on the mast for receiving an alarm from a distressed person, additionally contains a small rescue craft with a manual receiver-direction finding device, a manual receiving-and-direction finding device on the base boat and a radio identifier mounted on the body of a person in distress, while the radio identifier is connected by p radio channel with an omnidirectional antenna and hand-held direction finders both on the base vessel and on a small craft. The disadvantage of the prototype is the inability to provide an automatic response to the fall of a person overboard and thereby accelerate the delivery to him in an automatic mode of life support equipment, primarily thermal protection.

This system is closest in combination of essential features to the claimed and adopted as a prototype.

Since emergencies with people in distress at sea occur, in most cases, when they fall overboard any next vessel at sea or when falling over the perimeter fence, for example, offshore oil platforms or coast stations, the most urgent problem it remains to detect and provide them with life support equipment, primarily maintaining afloat and thermal protection in the very near future after they fall into the water beyond the perimeter of these marine objects (ships, platforms), since more than 60% of the surface The World Ocean has a temperature below 25 ° С, at which hypothermia conditions are created, at a temperature of 2-3 ° С, a stay of more than 15 minutes can become fatal, and at a temperature of 0 to -2 ° С, a fatal outcome occurs after five to eight minutes.

The task of the claimed invention is to significantly accelerate the delivery of life support equipment to a person, primarily thermal protection, by creating an automatic response system and auto-reset of rescue floating equipment, by instantly (up to 60 sec) detecting the fact that a person crosses the perimeter of these offshore (base) facilities, auto-dumping (up to 120 sec) from the base facility and the direction to them of a robotic rescue floating craft, which is located at the facility itself before the emergency. In this case, the following effect is achieved - for example, at a ship speed of up to 60 km / h (32.4 knots), the maximum distance between a person in the water and a robotic rescue craft will be up to 3 km, which in turn will greatly simplify the search for a person and speed up raising it to a life-saving floating vehicle or delivering to it life-support equipment in the form of a hydro-thermal suit, NZ, means of maintaining it afloat and independent movement.

In practice, it is possible to achieve a significantly shorter distance between a robotic rescue floating craft and a person to 0.5-1 km or less by reducing the response time of the rescue detection system and dropping a robotic rescue floating craft to 30 seconds or less.

The claimed technical result is achieved by the fact that rescue floating equipment before an emergency, in the form of a person falling overboard, is located at the base object where people are located, and after a person gets outside the vessel or the base object, the robotic rescue rescue auto-reset -facilities equipped with thermal protection, which in turn, by reducing the distance between the person and the rescue tool, accelerates the delivery of thermal protection to him and significantly increases the chances of survival in cold waters.

The proposed search and rescue system consists mainly of three components.

1. The base facility, which is equipped with the means:

- tracking the perimeter of the base object (guarded perimeter);

-auto-reset of active robotic rescue floating craft;

-tracking on objects, both for rescue equipment, and for rescued people;

-possible control and adjustment of the movement and manipulation of a robotic rescue floating craft;

-automatic return of the robotic rescue floating craft to the base object.

2. A robotic rescue floating craft that contains the following systems:

-Bringing into working condition after auto-reset;

-control drives the start and operation of the engine and turning means;

-controlling all additional equipment, for example, manipulators;

- determining the location of the rescued;

-exchange of data with the base object, other rescue ships and rescued; -Approach in automatic mode to the rescued;

- deliveries to the salvage life support kit including thermal wetsuit, emergency kit;

- transportation of the rescued either automatically or semi-automatically (according to the program entered by the rescued —shore, base object, rescue boat), or in manual mode to collective rescue equipment, ship, shore, etc.

3. One or more objects in the form of a life jacket or bracelet that are on the salvage and are equipped with signaling devices in the form of radio transmitters, and are intended for:

-signal of a signal to the facility of the base object about the intersection of its perimeter (signal "man overboard-MOV");

-activation of the auto-reset system of a robotic rescue floating craft; - determine the location of the rescued and exchange data with the robotic rescue vehicle and the base object.

The life jacket can be additionally equipped with a detachable and helium-filled shell, inside which a corner reflector made of a metallized film is fixed. The shell, if necessary, can be filled with gas, for example helium, since it is lighter than air, and such a balloon can serve as an additional means for detecting the rescue. The cord-suspension of the shell is connected with the lifting line of the lifejacket, which allows you to lift a person on board the life-saving tool. The sheath material can be given properties that allow it to be detected in the infrared and optical ranges in order to use near-detection systems.

In FIG. 1 is a block diagram of a search and rescue system, FIG. 2 - scheme of the search and rescue system.

The search and rescue system consists of the base object 1 (vessel, oil platform, coast station), equipped with perimeter sensors around the perimeter 1.1, the signal from which is recorded in the adder 1 .2 (guarded perimeter of the base object). When an object crosses the perimeter, sensors 1.1 transmit a signal through the adder 1.2 to the command device 1.3 of the base object, which issues a command to the auto-reset means 1.4 of the rescue floating means 2, which is in the non-operational state on the base object until the auto-reset. The base object also contains a control and adjustment system for movement 1.5 of the robotic rescue floating craft 2, which can duplicate, in exceptional cases, a control and correction system installed on the rescue floating craft 2. To receive and execute commands, the systems of the base facility are equipped with a receiver - transmitting device 1 .6 associated with the command device 1.3.

The second element of the search and rescue system is a robotic rescue floating craft 2 (boat, liferaft, etc.), which is equipped with a 2.1 engine with a control system 2.2. including the direction of movement of the rescue floating craft 2. It also has a navigation system 2.3 installed on it, which allows it to receive signals from the transceiver located on the rescue facility 3 and through the control system 2.2 direct the robotic rescue floating craft 2 to rescue facility 3. On the tool 2 may be located additional equipment, such as a manipulator, which is controlled by system 2.4 control additional equipment. Since the rescue floating craft 2 is inoperative on the base object 1, then, after dumping it into the water, using the system to bring it into working condition 2.5 after the auto-reset, the rescue floating craft it is brought into working condition, for example, a gas-filled raft is filled with gas from a compressed gas cylinder built into it. All commands from the systems are sent to the command device 2.6. To receive and execute the commands of the base object 1 and the salvage object, the Zrobotized rescue floating vehicle 2 is equipped with a transceiver 2.7 associated with the command device 2.6. On the rescue floating craft 2, a life support kit 2.8 for the rescued, including a thermal wetsuit, and an emergency kit can be placed.

The third element of the search and rescue system is the rescue itself, which should be dressed in a life jacket with a transceiver at the time it gets into water or equipped with a so-called alarm bracelet with a transceiver (personal rescue equipment known from the prior art). In these means 3 there are: a signaling system to the facility of the base object about the intersection of its perimeter 3.1, a system 3.2 for signaling the auto-reset of the rescue craft 2 (as a backup system 1.4 of the base facility 1) and a signaling system 3.3 for determining the location of the rescued . All three systems are tied to a transceiver 3.4 or can act separately.

All three components of the search and rescue system are interconnected via transceivers 1.6, 2.7 and 3.4.

The constituent parts of all three elements of the claimed search and rescue system are known from the level, including rescue, of the equipment that currently exists in the world.

Search and rescue system operates as follows.

In the work scheme (Fig. 2), presented for the base object 1 in the form of a vessel, it follows the course determined by the dashed line. Guarded perimeter of the vessel - 1.1. On board the vessel there is a rescue floating vehicle 2 and people potentially affected by falling into the water in individual rescue equipment 3. At point A, a person falls overboard crossing the guarded perimeter 1.1 of the vessel (base facility 1). The signal about the intersection of the perimeter is transmitted to the command device 1.3 of the vessel, which issues a command to the auto-reset means 1.4 of the rescue craft 2. At point B, the rescue craft is reset. When splashed down (before splashdown), with the help of the system to bring into working condition 2.5 after auto-reset, the rescue floating craft is brought into working condition, for example, a gas-filled raft is filled with gas from a cylinder with compressed gas built into it. Navigation system 2.3 determines the direction (location) of a person according to the signals of the transceiver located, for example, in a life jacket. After determining the location of a person, the control system 2.2 includes engine 2.1 and a certain direction, the rescue floating tool 2 moves toward a person. In FIG. 2 dashed circle shows the area of interaction of the rescue vehicle and the person overboard. When the rescue vehicle is brought closer to and in contact with the person, the rescued person is placed on board, including with the help of a manually lowered ladder or with the help of a manipulator, the rescued person who is unconscious is automatically captured, and upon a signal from the ship or in manual control, the rescue floating vehicle is sent to a ship or another facility. An individual rescue vehicle may include, for example, a signaling system for the facility of the base object to intersect its perimeter and a signaling system for the auto-reset of the rescue craft, which are duplicates of the similar systems present on the vessel and increase the likelihood of helping the rescued to man. Also, life support equipment can be placed on a rescue floating craft -

Using the proposed search and rescue system as a robotic rescue complex will allow providing emergency assistance to people in cases where they are left overboard, and this assistance is rendered without the participation of a human operator in order to exclude the so-called “during human factor ”and reduce delivery time primarily thermal protection.
