Description

Alarm system about a threat to personal safety or about a threat to the state of health (options)

Technical field

The invention relates to the field of informing a person of certain subjects about getting him (a person) in an emergency, sending these subjects an alarm, calling for help to a person who needs help.

State of the art

Technical solutions are known in the art for the design of wearable on the human body, including in the form of a ring or ring, alarm devices made with the function of secretly sending signals about help and about their location to response services or other personalities. The patents also describe the design features of such a device in a simplified scheme using a processor, means for transmitting signals over a distance, and an alarm button.

So, there are known methods and devices for alarm notification, in which the so-called "panic button" is used - a miniature radio transmitter on whose body a control button is installed. The radio transmitter is activated by pressing the control button when there is a danger to human life, health and material values, in particular when there is a threat to an employee of the corresponding power structure. The radio signal (alarm radio signal) emitted by the "panic button" is received at the central security center and, after processing and decryption, is encrypted in the form of an alarm message indicating the identification signs of the "panic button" that emitted the panic signal. When an alarm message is indicated in the indicated central protection points, sound and / or light alarm is applied. Various device options for technical implementations of this method are presented, in particular, in the application US 001/0052848, G08B21 / 00 and in the patent US JY "63 10539, G08B23 / 00.

It is also known a device for alarming threats to personal safety, made in the form of a ring or ring, that is, in the form of a conveniently and constantly wearable thing, which does not cause the aggressor to form a negative attitude or suspicion (US2008182547, Н04М 1 1/04. Publ. 3 1.07.2008).

This patent describes a personal security threat alarm device comprising a housing made in the form of an annular element carried on the user's finger, in the inner cavity of which a power source, a processor unit, a microphone, and a voice signal transmission unit are mounted via wireless communication to an externally located receiver of this voice signal — a mobile phone that, in relay mode, is connected to a subject that provides security for the user, as well as Ms from the housing a button for initiating the generation of said signal is a signal alerting the user of the personal security threat, when submitting a voice message through a microphone processor unit.

From the same source (US2008182547) there is a known method for alarming personal security threats, which consists in registering on a mobile computerized means of communication the identification data of a ring or a ring that is worn on a user's finger, equipped with a processor unit, a microphone and a signal transmission unit via wireless communication by pressing a physical button on this ring or ring, and when signs of a threat to personal safety appear, they press a physical button to initiate the processor unit, ofona and signal transmission unit, and then carried out a voice message into the microphone on the ring or rings and transmit it in wireless mode to a mobile computerized communication means, wherein in relay mode, they transmit a signal about a threat to personal security to an entity endowed with the functions of implementing user security.

The disadvantage of this method is that using a voice message is problematic, because it is not always possible due to the circumstances of the situation and to work with a microphone, you need to bring the ring to your lips, which is sometimes impossible, and when moving away from the lips you need to raise your voice, which is also not always feasible. In addition, the user is not informed that an alarm has been sent or that the device is operating. In a difficult situation of a possible threat, the lack of feedback does not correspond to the psychological state of a person.

There is also a known method of alarming about a threat to personal safety, which consists in programming through the use of a mobile computerized means of communication of the user of the processor of a ring or ring worn on the user's finger, equipped with a signal transmission unit via wireless communication when a physical button is pressed on this ring or ring, and when signs of a threat to personal safety, they press a physical button to initiate the processor to form a signal, which is a signal scrap of alarms about personal security threats, and transmitting this signal wirelessly to remote access to at least one computerized means of communication in the form of a cell or mobile phone or smartphone belonging to a third-party user (RU 162348, G08B25 / 00, published 10.06. 2016).

From the same source, a personal security threat alarm system is known that contains user-programmable rings or rings on the user's finger that are programmed by means of a mobile computerized communication device and equipped with a signal transmission unit via wireless communication when pressed a physical button on this ring or ring when there are signs of a personal security threat, which is an alarm signaling a personal security threat, and transmitting this signal wirelessly to a remote access centralized assistance system made with the function of receiving signals from a user’s ring or ring

This decision was made as a prototype for the claimed object. A feature of the known solution is that it operates in a mode of small distance from the alarm receiver, which is caused by the use of a communication system using the Bluetooth protocol. This is one of the reasons why the user is obliged to use the relay mode, that is, the transmission of a signal through computerized means by other nearby users. In this regard, it is initially assumed that in this area there always exists a group of people with such means of calling for help, and at least some of these tools operate in relay mode. And this is understandable, since the feeling of possible fear or apprehension always forms a response feeling aimed at helping another person. Therefore, the task of transmitting a signal for help is completely solvable and is achieved precisely by the algorithm for transmitting a signal through computerized means of other users. Such a relay signal may be received by a specialized rescue service. But for such a specialized service it is not possible to get in direct contact with the user due to the remoteness of the location and due to the lack of a reverse communication channel.

For such systems of warning of personal danger, the determination of the coordinates of the location of the signal source also becomes problematic. In addition, the recognition of a situation as alarming or critical - this property is closely related to the psychology of the user and is often determined by personal assessments and association with previous experience. it says that not all situations that a particular user considers dangerous for themselves, in fact, relate to those. Therefore, when receiving a signal for help, a spirit of tasks is required; determination of the coordinates of the signal source location and confirmation of the fact of compliance with the hazard category that has developed on the spot. A well-known solution does not allow this to be done in a timely manner, even if the geolocation data is automatically included in the signal format. It takes time for the police to arrive at the source, for example, and upon arrival circumstances may be established requiring assistance other than the assistance that the police can provide.

At the same time, the main problem is the precise determination of the origin of the signal. If such a signal is carried out in the conditions of a settlement, that is, in the conditions of some formed infrastructure with the exact coordinates of the houses, the path of the streets and driveways, etc., then detecting the signal source with modern means of modern geolocation is possible with sufficient accuracy., But it takes time and subsequent refinement or correction of the coordinates of the real location of the signal source. This is determined by the fact that there is always a reference to buildings, which allows even with vague coordinates to carry out correlation and reach conditionally reliable coordinates.

However, the situation changes dramatically when it comes to a signal source coming from a ground or underground structure, which is distinguished, for example, by number of storeys (in relation to a multi-story building) or by branching of corridors or labyrinth (for cellars and underground passages). For such structures, geolocation data shows the place, that is, the building itself, but does not show on which floor and in which part of the floor this source is located. As a rule, in such cases they comb all floors and basements until the reason for the search is will be detected. But such operations require a lot of people and it takes a lot of time.

In addition, situations are possible when a person searching cannot be in the building, for example, in the event of smoke due to fire or gas contamination and for other reasons. That is, sometimes there are restrictions on the presence of people in such structures and this requires the involvement of rescuers with special equipment. This also takes time, which can have a detrimental effect on the fate of the user who has sent the rescue signal. In addition, any rescue operations are accompanied by technical noise, the presence of which may frighten offender. To date, the search for people in structurally developed structures such as warehouses, factories, factories, or cellars extended in length and development is a complex and time-consuming task, the solution of which involves a large number of people.

The best embodiments of the invention

According to the present invention, there is considered a warning system about a threat to personal safety or a threat to a state of health (Fig. 1), based on the fact that some users carry with them, on their hands or on their hand, alarm devices about a threat to personal safety or a violation of their condition health. The system is considered both for a variant with an unlimited coverage area, and for a certain local territorial zone, which may represent some part of the territory in which these and other users are united according to one or more general characteristics (place of settlement, location, interest, or workflow )

In general, under the concept of “wearable user-programmed computer-based communication tools programmed by means of a mobile computerized communication device, equipped with a signal transmission unit via wireless communication by pressing a physical button on this tool or a touch button in the corresponding application on this computerized tool when there are signs of personal security risk "means communication means such as mobile and cell phones, smartphones, iPhones, etc. In addition, this concept includes a class of specialized means of communication related functionally to the means for issuing an alarm signal - rings or rings, bracelets, pendants, wearable items, accessories and any other forms of external performance, inside of which a processor controlled by the initiation button is mounted with a signal issuing unit on the air.

The computerized communications used by users are mobile or cell phones or iPhones or smartphones or other gadgets that allow communications. The computerized communication device worn by the user can be a ring or a ring worn on a user's finger or a bracelet or pendant worn on the hand, in the internal cavity of which a power source, a processor unit and a signal transmission unit are mounted via wireless communication to an externally located receiver of this signal, as well as physical button brought out of the case to initiate the generation of the specified signal, which is an alarm signal about a threat to personal safety user (or health status). The following is an example implementation using a ring or ring.

In addition, this device may be further provided with a location unit associated with the processor unit for transmitting in the signal packet an alarm signaling a threat to the user's personal safety and location coordinates. Or it can be additionally equipped with a signal receiving unit from a computerized means for inputting a signal to cancel sending a signal, which is an alarm signal about a threat to the user's personal safety. And as a signal transmission unit with an antenna, a unit using the Bluetooth protocol is used. Thus, a ring or ring are programmable by the application of a mobile computerized communication device worn on the finger of users of the device. In addition, such a ring-type tool may be equipped with an audio signal receiver with outputting an audio message to the speaker.

Such a computerized tool such as a ring or keychain, such as a device, includes the following configuration base, but not limited to: a power source (battery) 1, a vibration motor 2, a charge control board 3 power sources, a vibration motor control board 4, a processor unit 5, block 6 Bluetooth signal / reception transmission, antenna 7 for Bluetooth unit 6, physical button 8, LED (s) 9 (for visually demonstrations of ongoing processes - displayed on the inner side of the ring or ring splint), product body. An embodiment of the invention is possible in which the processor and the signal transmission unit via wireless communication are made in the form of a microprocessor board, which is a single-chip Bluetooth controller with an integrated processor that performs the functions of the processor and the signal transmission / reception unit via the antenna. A Bluetooth microprocessor module is understood, for example, as a Bluetooth chip CC2540 - a single-chip Bluetooth controller with an integrated processor that functions as a processor and signal transmission unit. Or, for example, AT76C551 is a single-chip controller designed to organize high-speed transmission of data over a radio channel over short distances in the allowed radio frequency range of ISM. The AT76C551 contains an RF processor. This processor performs all the processing, including modulation and demodulation, of the digital stream according to the Bluetooth standard. The device controls the transceiver and a predetermined speech coffee machine. The AT76C551 contains the ARM7TDMI microprocessor core, which supports working with external and internal memory via a standard microprocessor interface. Other layout solutions of the ring or ring are possible while maintaining the main components.

In addition, a cellular signal receiver can be mounted on the board, allowing you to input sound to the speaker, that is, receive sound (voice) messages and listen to them by the user.

All actions feed the battery. When you press the physical button 8 and hold it pressed for, for example, three seconds, the vibration motor 2, when interacting with the control board 4 of the vibration motor and the processor unit 5, vibrates all the time holding this button 8.

After, for example, three seconds, the processor unit 5 determines the expiration of this predetermined time and routes the signal through block 6, using antenna 7, aired. At this time, LED 9 can indicate system health. The device uses at least one LED that is displayed on the inner surface of the annular element next to the physical button 8. In this solution, the button for initiating the generation of a signal that is an alert signaling a threat to the personal safety of the user is brought out on the outer surface of the annular element in the second and the third quadrant in a clockwise direction. On the same side (from the side of the button) there is an LED indicator / indicator for light indication of the operating modes of the ring or ring.

Another embodiment of programmable via a mobile computerized communications application, wearable users can consider computerized communications equipped with a signal transmission unit via wireless communication by pressing a touch button in the corresponding application. These capabilities are available in most modern mobile communications such as smartphones 10, iPhones and some types of tablets. For these funds, you can use the appropriate mobile application or bind the existing native SOS button to this application.

A feature of the claimed invention is that the alarm signaling a threat to personal safety is sent to a centralized assistance structure 11 equipped with an interactive map of the area 12 for visual display on it of markers 13 corresponding to the coordinates of the location of the alarm source. It is significant that when using a Bluetooth microprocessor module in the ring or ring, the radius of action of such a transmitter is quite small (data transfer at speeds of up to 1 Mbit / s from 10 m to 100 m). In this regard, the means of receiving this signal, located at a distance of 300 meters or more, will not be able to respond to a signal for help, but these funds can communicate with each other in the mode of any distance. In this case, we are talking about distributed distantly relative to each other in some local territory (for example, a village, a sports camp, etc.) as separate signal receiving units, which are an alarm signal about a threat to the user's personal safety, or about a violation of his health and carrying data on the coordinates of the signal source. Under such means 14 can be considered the same rings or key chains or iPhones, smartphones made with the possibility of relaying signals. Since in the social community there is always a certain collective of people who are preoccupied or perplexed by a common problem, it can be said with a high degree of probability that in a certain area there will always be a person or persons who are in such radio access from each other that the signal sent to Bluetooth mode by one device will be caught by another device, etc. Thus, it is always possible to form a communication chain, through which a threat signal sent by one user through such repeaters will reach the rescue service located at a distance from the signal source that does not allow to directly receive this signal.

The centralized assistance system 11 is the generic name of such structures as the Ministry of Emergencies, the police, ambulance, rescue centers, etc. On this map, the marker system allows you to specify the area of the signal source by establishing the correspondence of the coordinates of the signal source with the location of specific objects on the ground in relation to the local infrastructure. On the map, there may also be real-time location markers of mobile assistance points, which will allow the operator of the centralized structure 11 to direct the corresponding patrol to the signal source zone without loss of time. This centralized assistance system 11 is configured to receive signals or phone calls from computerized means of communication of users, for which it is equipped with all necessary means of communication 15. Moreover, the centralized structure of assistance equipped at the location with at least one signal receiving unit, which is an alarm signal about a threat to personal safety or about the user's health condition,

Alternatively, if the computerized means of communication carried by users are equipped with a geolocation unit, and the alert signaling a threat to the user's personal safety carries data on the coordinates of the source of this signal, then the signal receiving unit, which is an alarm warning about the threat to the user's personal security, is in a centralized structure assistance is performed with the possibility of receiving a signal, which is an alarm signal about a threat to the personal safety of the user and Other data about the coordinates of the signal source.

Using such a ring or ring, it is possible to implement a method of alarming notification of a threat to personal safety or a violation of a state of health. This method consists in programming, using a mobile computerized means of communication, the user of the processor, a ring or a ring worn on the user's finger, equipped with a signal transmission unit via wireless communication when a physical button is pressed on this ring or ring, and when there are signs of a threat to personal safety, a physical button is pressed to initiate a processor for generating a signal, which is an alert signaling a threat to personal safety, and transmitting and this signal by wireless communication in remote accessibility to at least one computerized unit belonging to a centralized infrastructure aid. In this case, the signal is transmitted through means 14.

The user, to initiate the processor and the signal transmission unit to generate a signal about a threat to personal safety, presses the physical button on the ring or ring and hold it pressed state N seconds, after which the processor generates a signal and transfers it to the signal receiving unit for broadcasting. In this case, the user receives a response of the ring or ring due to the sound and / or light and / or vibrational alarm about the arrival of this signal in the radius of action of the receiving unit of the ring or ring of the user.

The centralized system 11 first receives a signal that has been relayed through computerized communications and records the receipt of the signal as a reason for turning on the hardware systems. A signal for help is sent at the initiative of the user. The receipt by the centralized system 11 of an alarm signal (about a life threat or a deterioration in the state of health) is perceived by this system as a reason for turning on the hardware systems.

In the framework of solving the first problem, two options are possible. The first is receiving a signal for help, in the data set of which the coordinates of finding the source of this signal have already been entered. This is possible if the computerized means of communication carried by users have an appropriate application or a built-in communication program with a coordinate determination system (iPhone, iPad, etc.). Upon receipt of such a signal on an interactive map of the area 12, these coordinates are programmatically stored in memory and visually displayed in the form of a marker 13, clearly showing the correspondence of the coordinates of the location of the alarm source to the terrain plan. If the received signal does not carry information on geolocation, then the software and hardware centralized system 11 automatically determines these coordinates by taking indicators from distantly located towers to obtain a coverage area of 100 m 2 to 1 km 2 In this regard, it is mandatory the fact that the centralized assistance structure should be equipped at the location with at least one signal receiving unit, which is an alarm signal made with the possibility of implementing the function of determining the geolocation of the source of this signal.

Upon receipt of exact or conditional (not accurate) coordinates of the location of the alarm source and comparing them with the plan of the area (city, forest, park, residential quarter, etc.), it becomes necessary to obtain reliable information about the event to clarify the type of assistance and accept measures to provide this assistance (or to establish the fact of a user's erroneous assessment of an alarm event). For this purpose, the centralized aid assistance structure has at its disposal a fleet of unmanned aerial vehicles 16 (drones) and is equipped with a control unit 17 for at least one unmanned aerial vehicle 16, which is equipped with a video recording tool and an audio recording tool for sounding environmental signals (audio recording means, in particular , the microphone may have a performance protected from the noise of the aircraft’s engines, that is, these noises are not perceived and are not reflected in the recording). Means of video recording and audio recording are not shown. When establishing the location coordinates of the source of the alarm signal from the control panel of the centralized assistance structure, the drone sends a signal to the drone to turn on the engines and make a flight (for example, in automatic piloting mode) to the zone of the location of the source of the alarm signal via control channel 19. The issues of automatic piloting of the drone have already been resolved today and practice shows that such piloting is possible if the drone program includes a map of the terrain, reference points and the position of buildings (i.e. obstacles), etc. relative to which in the drone’s memory there is a base of flight routes, the choice of each of which directly depends on the coordinates of the end point of the flight. In this regard, the control unit 18 of at least one unmanned aerial vehicle of a centralized assistance structure 11 is configured to receive data on geolocation of the signal source and the direction of the unmanned aerial vehicle in the zone of the signal source.

When the source of the alarm signal is in the coordinate zone, the drone starts to record and record the environment and transmits these records via the data transfer channel 20 through the real-time control unit 18 to the emergency assessment center of a centralized assistance structure. In this regard, the centralized structure for providing assistance is configured to receive real-time broadcast signals from video recording and audio recording audio signals when the unmanned aerial vehicle is in the area where the signal source is located. The drone's route in the area of the location of the alarm source may be circular in order to fully cover this area. In addition, at the time of the broadcast, the operator of an emergency assessment center of a centralized structure can make adjustments to the piloting or hovering of the drone and manually change the altitude of its flight. In twilight or night conditions, it is possible to use a lighting device on the drone. The appearance of the drone at the scene of the event also prevents a number of serious violations, as it is direct evidence of control by the relevant public order services.

Obtaining real video information, accompanied by sounds of the external environment, allows you to quickly assess the current situation around the user and take appropriate assistance measures. In particular, the drone (unmanned aerial vehicle) is equipped with a communications signal repeater (not shown). And the centralized structure for providing assistance is made with the possibility of receiving in real time the transmitted signals from video recording and audio recording audio signals at the time the unmanned aerial vehicle is in the area where the signal source is located, determining a real picture of what is happening and the issuance of a control signal to turn on the repeater on the unmanned aerial vehicle in the user’s area for direct communication of the signal sender with the helpdesk and transmission of voice messages for the user from the rescue service in cellular mode. This allows you to issue instructions to the victim to provide advisory and advisory assistance before the arrival of a mobile group of rescuers. The use of a repeater on the drone allows direct remote radio communication with a specialized structure and communication, for example using short-range Bluetooth communications, with the user.

For such warning systems about personal danger threats, it becomes problematic to determine the location coordinates of the signal source. In addition, the recognition of a situation as alarming or critical - this property is closely related to the psychology of the user and is often determined by personal assessments and association with previous experience. This suggests that not all situations that a particular user considers dangerous for themselves, in fact, relate to those. Therefore, when receiving a signal for help, a spirit of tasks is required; determination of the coordinates of the signal source location and confirmation of the fact of compliance with the hazard category that has developed on the spot. A well-known solution does not allow this to be done in a timely manner, even if geolocation data are automatically included in the signal format. It takes time for the police to arrive at the source, for example, and upon arrival circumstances may be established requiring assistance other than the assistance that the police can provide.

At the same time, the main problem is the precise determination of the origin of the signal. If such a signal is carried out in a settlement, that is, in the conditions of some formed infrastructure with the exact coordinates of the location of the houses, the trajectory of streets and thoroughfares, etc. etc., the detection of the signal source by modern means of modern geolocation is possible with sufficient accuracy., but it takes time and subsequent refinement or correction of the coordinates of the real location of the signal source. This is determined by the fact that there is always a reference to buildings, which allows even with vague coordinates to carry out correlation and reach conditionally reliable coordinates.

But the situation is greatly complicated when it comes to unfamiliar terrain. The concept of unfamiliar is understood as a locality that does not have map-fixed reference points (forest, village away from the city, location of the sports camp, people went camping, etc.). That is, for a centralized aid structure, such an area is on the map, but it does not apply to an area with structured infrastructure.

For such areas or such a locality, receiving a signal for help indicating the coordinates of the signal source is a solution to the problem of combing through a fairly large area.

For example, a simple indication of the coordinates on the map is not suitable, because the error of the geotags reaches 200 mV - a person could come along the coordinates in search of a small thing, but it turned out that there were still hundreds of steps to the place. When using modern cell phones with a built-in compass and GPS, the checks showed the following maximum accuracy we obtained under good reception conditions:

• iPhone 4 — Hume,

• iPhone 4s and 5-5m.

This accuracy was requested from the phone itself through location.horizontalAccuracy, and the location was received from LocationManager at maximum accuracy and refresh rate. But in many instructions write that good conditions also imply the absence of trees. It turns out that when the phone does not pick up GPS, then ± 1414 meters are displayed in location.horizontalAcuracy using information from the operator’s base station. Such accuracy is produced by GSM networks. If there are Wi-Fi points nearby, according to which geographical coordinates are set, then, as a rule, accuracy increases to hundreds of meters, if there is only one Wi-Fi point, or tens of meters if there are several. Thus, the picture of the difficulty in determining the exact coordinates in poor communication conditions or in the absence of GPS is clearly visible (article "Where is the iPhone buried or how accurate is GPS?", By Max Goncharov, 03/01/2013, posted on the Habrahabr website on the Internet address: https://habrahabr.ru/post/171117/) The spread of ± 1414 is approximately a site in 2 square meters. km If this site falls on difficult rugged terrain or on a piece of forest, then the search for the source can be very long. It should be borne in mind that without knowledge of the roads and ways of access to this site, the movement of mobile means of assistance can be greatly complicated.

A signal for help is sent at the initiative of the user. The receipt by the centralized system 11 of an alarm signal (about a life threat or a deterioration in the state of health) is perceived by this system as a reason for turning on the hardware systems. A second example of the execution of the system (Fig. 2), which ensures the exact position of the alarm source, is considered.

In the framework of solving the first problem in this example, two options are possible. The first is receiving a signal for help, in the data set of which the coordinates of finding the source of this signal have already been entered. This is possible if the computerized means of communication carried by users have an appropriate application or a built-in communication program with a coordinate determination system (iPhone, iPad, etc.). When receiving such a signal on an interactive map of the area 12, these coordinates programmatically stored in memory and visually displayed in the form of a marker 13, visually showing the correspondence of the coordinates of the location of the alarm source to the terrain plan. If the received signal does not contain information on geolocation, then software and hardware centralized system 11 automatically determines these coordinates by taking indicators from distantly located towers to obtain coverage from 100 m to 1 km. In this regard, it is imperative that that the centralized assistance structure should be equipped at the location with at least one signal receiving unit, which is an alarm signal configured to alizatsii GEOGRAPHICLOCATION source determination function of this signal.

Upon receipt of exact or conditional (not accurate) coordinates of the location of the alarm source and comparing them with the terrain plan, it becomes necessary to obtain reliable information about the event to clarify the type of assistance and take measures to provide this assistance (or to establish the fact of an erroneous assessment by the user of an alarm event) . For this purpose, the centralized aid assistance structure has at its disposal a fleet of unmanned aerial vehicles 16 (drones) and is equipped with a control unit 17 for at least one unmanned aerial vehicle 16, which is equipped with video or photo capture means for creating two-dimensional or three-dimensional digital images and means fixing the height at which each digital image is taken, the angle of rotation of the video or camera, and the longitude and latitude data corresponding to the position of the unmanned aerial vehicle in moment of receipt of each digital picture. In addition, such a drone is equipped with a real-time transmitter of digital image files directly to the server 21 of the centralized assistance structure 11 or to the cloud storage, to which the centralized assistance structure has access to download these files to the server 21 of this structure. All of these tools are not shown.

When establishing the location coordinates of the source of the alarm signal from the control panel of the centralized assistance structure, the drone sends a signal to the drone to turn on the engines and make a flight (for example, in automatic piloting mode) to the zone of the location of the source of the alarm signal via control channel 19. The issues of automatic piloting of the drone have already been resolved today and practice shows that such piloting is possible if the drone program includes a map of the terrain, reference points and position of obstacles, etc. relative to which in the drone’s memory there is a base of flight routes, the choice of each of which directly depends on the coordinates of the end point of the flight. In this regard, the control unit 18 of at least one unmanned aerial vehicle of a centralized assistance structure 11 is configured to receive data on the geolocation of the signal source and direct the unmanned aerial vehicle to the zone of the signal source.

When the source of the alarm signal is in the coordinate zone, the drone starts making video or photo recordings of the environment and transmits these records via the data transfer channel 20 through the real-time control unit 18 to the emergency assessment center of a centralized assistance structure. In particular, there are two possible options for data transfer: directly to the server 21 of the centralized assistance structure 11 or to the cloud storage, from where the server has the ability, in accordance with its capacity, to transfer data and process it in specialized software to obtain 3D model 22 (bulk) terrain on the flight path of the drone.

The drone's route in the area of the location of the alarm source may be circular in order to fully cover this area. Besides, in The moment of the broadcast, the operator of the emergency assessment center of a centralized structure can make adjustments to the piloting or hovering of the drone and change the altitude of its flight manually. In twilight or night conditions, it is possible to use a lighting device on the drone. At the same time, terrain images can be captured by the drone’s equipment not continuously from the beginning of the flight, but by receiving a control signal to turn on video or photo fixation means in the user's area and transfer them to the centralized assistance structure for creating a 3D terrain model in software location coordinates of the alarm source to determine the exact location of this source. Two-dimensional shooting from a height makes it possible to evaluate the plan of the location of objects on the terrain, but does not give an idea of the relief of this terrain. And the signal source can be located in a zone closed or covered by the same tree or building or in a ravine. Therefore, a three-dimensional terrain model allows you to better assess reality and suggest the exact location of the signal source. This is also important because such a model allows you to clearly understand the possibilities of approaching this place or landing a helicopter.

Obtaining real video information allows you to quickly assess the current situation around the user and take appropriate assistance measures. All digital data (digital images) is received in real time by a centralized assistance structure, where server 21 programmatically generates fragments of a 3D terrain model in the coordinates of the location of the alarm signal source.

In 2016, it became known (article “3D Drones Robotics will be able to create 3D terrain models”, posted on 03/10/2016 u / on the DRONE2.RU website on the Internet at: http: //drone2.ra/news/ 33-drony-3d-robotics-smogut- sozdavat-3d-modeli-mestaosti.html), which is part of the solution to the important problem of 3D Robotics, together with Sony and the Autodesk software company, created the Solo unmanned aerial vehicle, which scans the terrain on the fly and immediately uploads the already built Ze-model to the cloud storage. As an example, the Solo drone monitors bridges and overpasses for their deformation and displacements. So far, the Solo drone has been working with GoPro cameras, but new versions will receive a special Sony UMC-R10C camera, which will be complete in the corporate version of the drone. The camera will allow you to take better pictures and videos, as well as upload files to the cloud without the need for landing, as described above. The drone is equipped with a Sony tablet with pre-installed special FORGE software from Autodesk. And the company for the production of flying radio-controlled devices DJI took up the development of the drone Agras MG-1 for working with fields and crops.

On June 19, 2016, it became known that for the Solo drone, an aircraft with built-in intelligence, 3DR on its website published software designed to control Solo. The user, using a minimum number of actions, will be able to collect data, process it and send it to any of the popular programs for working with 3D data: AutoCAD, Civil 3D, InfraWorks or Revit. At the same time, the company provides a convenient online service through which data is processed. For example, in Autodesc ReCap 360, you can create three-dimensional digital terrain models, as well as adjust the data of a point cloud obtained during the scan (article "3DR company drone for 3d terrain scanning", posted on 06/19/2016 u / on the 3D-DAYLI website on the Internet at: https: // 3d- daily.ru equipment / 3dr-dron-named-solo.html).

Currently, there are more than a dozen programs, both domestic and foreign, allowing you to create 3D reconstructions from images. Among them: Agisoft Photoscan, Photomod, pix4d and others. For example, in the pix4d program, information about each photo is recorded in an EXIF file: at what height it was taken, at what angle the camera was rotated, and what data is longitude and latitude. The program uses machine vision and photogrammetry technology to find common points in many photographs. To learn the geo data and the angle of rotation of the camera, each pixel is searched for color matching in other photos. Every match becomes a key point. If a key point is found in three photos or more, the program builds this point in space. The more key points, the easier it is to determine the coordinates of a point in space. From here follows the main rule - to maintain a large intersection between photos. Program developers recommend an intersection of 60 to 80%.

The spatial coordinates of each point are calculated by the method of triangulation: a line of sight or ray is automatically drawn from each survey point to the selected point, and their intersection gives the desired value. The algorithms used in photogrammetry are aimed at minimizing the sum of squares of the set of errors, usually solved using the Levenberg-Marquardt algorithm (or the bundle method), based on the solution of non-linear equations by the least squares method.

The collection of all 3D points is called a point cloud. During photo processing, an expanded point cloud is created that is used to generate a surface composed of triangles (polygons, meshes). The last step is to calculate the resolution (pixel size) and which pixels in the photo correspond to which mesh. To do this, the 3D model is deployed in a 2D plane and then the 3D position of the point is mapped to the original photo to set the color.

Photographing is carried out on any camera: soap dishes, DSLRs, GoPro, Canon 5D Mark III and even a thermal imager. Pix4d command Collaborates with many manufacturers of multirotors and gliders - such as SenseFly, Aeryon, 3DR, Delair Tech, Skydrones - which come with their software products for setting automatic mission parameters and use pix4d technology. The protocol MAVlink (Micro Air Vehicle Link), intended for data exchange between the control system inside the drone, as well as between the drone and the ground station, unites them all. The protocol is used to transmit GPS spatial position, drone orientation and speed. The automatic mission currently has the following characteristics: height 50 meters, area size: from 10x10 to 200x120 - this restriction is caused by the battery life and the level of Wi-Fi signal reception, the drone speed is 2-5 m / s, it takes off every 10 meters, the angle camera tilt from 0 to 90 °. The accuracy of the shooting depends on the height difference of the rented area and the presence of buildings and trees. With an automatic mission, the GSD is approximately 2.2 cm / pixel. GSD is the distance between the centers of the pixels measured on the surface. The higher the photographs are taken, the higher this value and the less details are visible.

Using images in the infrared and red colors, you can get a dynamic picture of the processes of changing the boundaries and characteristics of various types of vegetation (monthly variations, seasonal variations, annual variations), as well as the places of cutting and attack of insect pests or, conversely, observe the process of vegetation restoration . Such capabilities allow the use of drones at any time of the year and in any weather conditions to create a three-dimensional model of the place of origin of the alarm signal source.

Thus, the centralized structure 11 is able to obtain a three-dimensional model of the terrain by the first coordinates of the location of the source and determine the correlatively exact location of this source. After that, information about the exact location (point coordinates) of the location of the signal source, and therefore the user, along with a three-dimensional map of the terrain, according to its 3D model, they are transmitted to the mobile unit 23 of this structure, which is already directed or will be directed along these point coordinates to assist the user. In addition, in conditions of rough terrain or terrain with an unfamiliar terrain or for terrain not suitable for movement (lack of expensive, snowy or watery) according to the 3D terrain model, we can assume an optimized route along which the moving unit can reach a given point or even reach her.

Below is a third example of the system (Fig. 3)

Upon receipt of exact or conditional (not accurate) coordinates of the location of the alarm source and comparing them with the terrain plan, it becomes necessary to obtain reliable information about the event to clarify the type of assistance and take measures to provide this assistance (or to establish the fact of an erroneous assessment by the user of an alarm event) . In this case, we are talking about receiving a signal for help coming from, for example, a multi-story building. The received signal indicates its presence in this building, but it is not known in which part of it, on which floor and in which part of the floor. That is, there is a problem with several unknowns, the solution of which must be completed in a short time and without involving a large number of technical people. As a rule, the centralized structure for providing assistance at the place of its location in a city or settlement or in a region has a limited staff of specialists in the normative time allotted for this. But these standards are designed for regular situations, that is, those for which the place of the event and its appearance are precisely defined. But these forces are not enough if the situation is abnormal and requires the need to resolve it as soon as possible.

It is for this purpose that the centralized aid structure has at its disposal a fleet of unmanned aerial vehicles 16 devices (drones) or at least one, and is equipped with a control unit 17 for at least one unmanned aerial vehicle 16, which is equipped with video or photo fixation means for creating two-dimensional or three-dimensional digital images and means for fixing the height at which each digital image, the angle of rotation of the video or camera, and data longitude and latitude corresponding to the position of the unmanned aerial vehicle at the time of receipt of each digital image. In addition, such a drone is equipped with a real-time transmitter of digital image files directly to the server 21 of the centralized assistance structure 11 or to cloud storage, to which the centralized assistance structure has access to download these files to the server 21 of this structure. Also, these drones are equipped with means to control the distance to wall obstacles (for example, rangefinders, ultrasonic sensors - as used in parking systems for cars) and the transmission of digital images and data on distances to wall obstacles. All of these tools are not shown.

When establishing the coordinates of the source location, the alarm signal, that is, the address of the building, and from the control panel of the centralized assistance structure, to the block 18, a drone signal is transmitted via the control channel 19 to turn on the engines and make a flight (for example, in automatic pilot mode) to the area of the source location alarm The issues of automatic piloting of the drone have already been resolved today and practice shows that such piloting is possible if the drone program includes a map of the terrain, reference points and position of obstacles, etc. relative to which in the drone’s memory there is a base of flight routes, the choice of each of which directly depends on the coordinates of the end point of the flight. In this regard, the control unit 18 of at least one unmanned aerial vehicle of a centralized assistance structure 11 made with the possibility of obtaining data on the geolocation of the signal source and the direction of the unmanned aerial vehicle in the area of the signal source.

When the source of the alarm signal is in the coordinate zone, the drone starts making video or photo recordings of the environment and transmits these records via the data transfer channel 20 through the real-time control unit 18 to the emergency assessment center of a centralized assistance structure. In particular, there are two options for transferring data: directly to the server 21 of the centralized assistance structure 11 or to cloud storage, from where the server has the ability, in accordance with its capacity, to transfer data and process it in specialized software to obtain a 3D model (volume) of the building.

In particular, when approaching a building, a drone scans this building and transmits the scan results 24 and digital images to recreate the appearance of the building 25 and determine the place of possible penetration into this building

The drone's route in the area of the location of the alarm source may be circular in order to fully cover this area. In addition, at the time of the broadcast, the operator of an emergency assessment center of a centralized structure can make adjustments to the piloting or hovering of the drone and manually change the altitude of its flight. In twilight conditions or at night, it is possible to use a lighting device or a thermal imager on the drone. At the same time, terrain images can be fixed by the drone’s equipment not continuously from the beginning of the flight, but by receiving a control signal for turning on video or photo fixation means in the user's area and transferring them to the centralized assistance structure for creating a 3D model of the building in the software coordinates of the location of the alarm source. Obtaining real video information allows you to quickly assess the current situation around the user and take appropriate assistance measures. All digital data (digital images) is received in real time by a centralized assistance structure, where server 21 programmatically generates fragments of a 3D terrain model in the coordinates of the location of the alarm signal source.

Using images in the infrared and red colors, you can get a dynamic picture of the processes of changing the boundaries and characteristics of various types of coatings on a building. Such capabilities allow the use of drones at any time of the year and in any weather conditions to create a three-dimensional model of the place of origin of the alarm signal source.

When finding the opening, the drone penetrates into the building and begins to fly indoors 26 on the basis of indications of wall obstacles. Such flights are naturally justified if there are open openings between the rooms in the building, which allows the drone to scan not a separate room or hall, but a group of rooms or a whole floor. In any case, the drone makes it possible to very quickly (at a speed of 20 m / s) take a photo of a large area and give an idea in 3D about the presence or absence of the user on this area. Currently, there is open information about the creation of drones that can move at speeds of less than 20 m / s, which allows the drones to freeze or move slowly in order to more accurately detail the object.

Today it is already known that the American company TiaLinx introduced a model of the unmanned aerial vehicle Phoenix 40-A, which is designed to patrol territories and detect living creatures. Phoenix 40-A is equipped with a motion detector, video cameras, a night vision device and a UWB-radio scanner with Sense- technology Through-the-Wall (STTW). This device pierces through concrete and can catch the breath of a person hiding inside. In addition, a remote-controlled drone can study the layout of the building. Thus, the use of the drone in the structure of the building’s premises allows you to quickly identify the location of the user and, therefore, the source of the alarm signal (see the article “The new drone can recognize human breathing inside the building”, 03.22.2011, posted on the Geektimes website in Internet at: https://geeknmes.ru/post/! 15988 /).

Thus, the centralized structure 11 is able to obtain a three-dimensional model of not only the building from the outside, but also the premises inside the building. After that, information about the exact location (point coordinates) of the signal source, and therefore the user, along with a 3D map of the building and the premises using 3D models of the ground or underground structure is transmitted to the mobile unit 23 of this structure, which is already directed or will be sent along the specified route to point coordinates to assist the user.
