Description

The useful model belongs to training simulators, is a hardware and software complex for teaching and consolidating the skills of handling a fire extinguisher (the primary means of extinguishing fire) during the simulation of extinguishing fire sources of different 4 classes of fires and can be used in the training process of fire safety to gain practical experience of fire extinguishing indoor and outdoor fire extinguisher, as well as tests of acquired skills.

A large number of fires occur every day, the extinguishing of which with improvised means at the early stages of development would prevent significant material losses. Fire extinguishers are the primary means of extinguishing fires and are intended for use by employees of organizations, personnel of fire protection units and other persons to fight fires.

However, the staff of industrial facilities, public buildings, and social security facilities cannot always use a fire extinguisher correctly after training, or make mistakes in their work that lead to various injuries. Difficulties in the use of fire extinguishers are marked as ignorance of the principles of fire extinguishing, inability to apply knowledge in practice, fear of impressive fire factors. Thus, training the population to work safely with fire extinguishers is an important element of fire prevention.

Known devices allow for fire training of individuals, for example, training in controlled conditions of live fire. Due to high cost, high risk of injury, exposure to hazardous and environmentally hazardous substances, lack of quantitative and qualitative feedback, and lack of user manuals for the latest devices and systems, these systems are limited and often impractical for the private, commercial, and government sectors.

Accordingly, there is a need for a device, method, and system that addresses at least one of the above and other deficiencies in the field of individual fire training.

A training complex is known for practicing the actions of using fire extinguishers, consisting of a fire extinguisher simulator, which includes a fire extinguisher housing with a closing-starting device and a pressure gauge, in which a steam generator is attached to the fire extinguisher housing, which includes a heating element and a container filled with a substance for generating steam , connected to the power supply unit and the mixer in the form of a jet pump, which, in turn, is connected to the closing-starting mechanism of the fire extinguisher body, which serves for mixing

From steam and air and is under pressure in the body of the fire extinguisher simulator and their supply through a tube for releasing a stream of vapor-air mixture that simulates the release of a fire extinguishing substance, in a body made of moisture-resistant material with holes for air intake by fans and has a removable front panel made in the form of fine-cell nets, for simulating a fire and recording the correct performance of the exercise, a fire simulation and indication block is installed, which includes optical-electronic smoke detectors, remote optical signaling devices and light and sound alarms; at the same time, the elements of the fire simulation and indication block for control according to a preselected algorithm are connected to the control device; for the power supply of the power supply unit, which supplies the specified voltage to the steam generator, and the control device, they are connected to an autonomous power supply source (КИ 2773813 С1, IPC: 5098 9/00, publ. 06/09/2022, Bull. Mo 16).

A fire training device is known which includes a control unit that accepts input data and automatically provides output data according to the input data, and a firefighting training device that includes a flame generation unit coupled to the control unit

ИКА20070002046А, IPC: 098 19/00, publ. 07/31/20121.

Also known is a fire extinguishing training system with a monitor for displaying fire image information and fire extinguishing training, which includes a fire extinguishing signal simulator on a monitor that displays fire image information, a protective film that protects the monitor and receives a fire extinguishing signal to determine the position of the object, and for various fire situations, and a computer to locate the fire extinguishing signal and transmit as an image whether the fire is extinguished or not

ИКА20070091885 А, IPC: С09В 9/00, publ. 12.09.20071.

The above devices overcome at least one of the above and other disadvantages and, in particular, provide a training device and method for fire training that is optimal and effective.

However, the main disadvantage of these training complexes is the high cost, which limits the possibility of their use and does not ensure the effectiveness of the process of practicing the skills of using fire extinguishers.

A simulator for training firefighters and rescuers is known, which includes a thermal smoke chamber separated by partitions that form a labyrinth with different routes for its passage. Partitions have locks that are made in the form of electromagnetic locks with remote control. The thermal smoke chamber can be made mobile.

Electromagnetic locks through relay modules can be connected to microcontrollers that change the state of the lock according to the specified program KO 48092, (3098 9/00, 20051).

Such a simulator is intended only for training firefighters and rescuers in conditions close to the conditions of work at fires and disaster sites.

A modular simulator is known, which includes at least three modules divided into compartments and located on one metal frame. The first module contains a compartment where a fire simulator and fire extinguishing means are installed; in the technical compartment of this module, the regulators of the ignition hearth simulator, the smoke generator, supply and exhaust fans are installed; in the second module, a control unit for the ignition simulator regulators and smoke generators controlled by the operator is installed; the third module has an entrance door, an internal staircase and a corridor connected to the first module. The simulator may additionally include a fourth module, fifth and sixth modules identical to the first module. In this case, the fourth module is installed on the third module, the fifth module is adjacent to the first module, and the sixth module is installed on the fifth module. An identical seventh module can be installed on the third module, in which a corridor connected to the fourth and sixth modules is made. The equipment of the modules is connected to the control units by internal and external multicore cables. The modular simulator is easily assembled and disassembled, and can be quickly moved to a new location |ISA Me2086475,

Ab2S 39/00, 19931.

However, the specified simulator has limited functional capabilities and provides only practice of fire extinguishing techniques.

The closest thing to a useful model that is claimed is a simulator for practicing fire-fighting skills, which includes a fire extinguisher, the appearance of which is as similar as possible to the appearance of a real fire extinguisher, in which the fire extinguisher is electronic, in the body of which a fire extinguisher module is mounted, which is wirelessly connected through the server module with a personal computer, which is connected to a projector for displaying information on the screen by a wired connection, while the simulator contains a base, the module of which is connected via wireless communication with the server module and the electronic fire extinguisher module (ША 93830 0, IPC : Ab2C 2/00,

From publ. 10.10.2014, Bull. Mo 191.

However, this simulator has insufficient effectiveness of the training process, mobility and significant cost.

The useful model is based on the task of creating a hardware and software complex for learning and consolidating skills in handling a fire extinguisher, which would increase the effectiveness of the process of teaching the correct execution of the necessary procedure for extinguishing a fire with a fire extinguisher and practicing the skills of using fire extinguishers, significantly increasing the cyclical use of the proposed training complex , increasing its mobility and reducing its cost.

The task is solved by the fact that the hardware and software complex for teaching and consolidating the skills of handling a fire extinguisher, which includes a fire extinguisher dummy with a built-in module connected to an information processing unit and a system for displaying information on the screen, according to a useful model, is equipped with a virtual reality helmet with right and left controllers and a virtual reality headset with an internal operating system linked to a mobile application, where the left controller for controlling and inputting information for the mobile application includes an analog stick and X and Y keys, and the right controller acts as a transmitter of commands to a virtual reality helmet and a position marker connected by a loop wire through a connector with a fire extinguisher module,

The "SIM" hardware and software complex can be additionally equipped with an M/i-Gi-router for organizing a wireless UMi-Ri network and providing connected subscriber devices with access to the "Internet" network.

In the "SIM" hardware and software complex, a virtual reality headset can include simulators of wind direction, the presence of conditional current and the choice of a fire extinguisher.

Compared to the nearest analogue, the "SYM" hardware and software complex for training and consolidating skills in handling a fire extinguisher, which is claimed, has a smaller mass and is cheaper to manufacture.

It is possible to use the "SIM" hardware and software complex for teaching and consolidating fire extinguisher handling skills without a special expensive and bulky screen, only using a computer and a projector in any room.

A useful model is explained by illustrations, where: because - in fig. 1 shows a photo of an illustrative diagram of a fire extinguisher layout;

- in fig. 2 - a photo of the conventional diagram of the interaction of the wind with the jet of the fire extinguisher is shown; - in fig. C - a photo of the conditional extinguishing scheme against the wind is shown; - in fig. 4 - a photo of the analog drain is presented; - in fig. 5 - a photo of the working area of the analog drain is presented.

In fig. 1 presents an illustrative diagram of the layout of the VVK-3.5 fire extinguisher with a rubber stand for the VVK-3.5 fire extinguisher and a bell. At the same time, the bell can be disconnected from the fire extinguisher. Also, this illustrative diagram schematically shows the switch for the sound accompaniment when the trigger is pressed, the holder for the right controller Osshiv5 Optsevi2, the right controller Osshi5 Optsevi 2, the connecting wire loop, the power supply for batteries of the type

AA, trigger lever.

The design of the "SYM" hardware and software complex for training and consolidating skills in handling a fire extinguisher according to the claimed useful model meets the following requirements, according to the example of implementation.

The fire extinguisher module is mounted in the body of the model carbon dioxide fire extinguisher VKK 3.5 (SU-5) with a fixed nozzle, which can be disconnected during transportation.

The appearance of the fire extinguisher module is as similar as possible to the appearance of the original VKK 3.5 (SU-5) fire extinguisher.

When the trigger is pressed, a command is transmitted to the Osshi5 Otsevi 2 controller connected via a loop wire.

Also, when the trigger is pressed, an audiovisual accompaniment sounds in the form of a noise similar to that produced by a real VKK 3.5 (OU-5) fire extinguisher in operation. The volume is comfortable, average.

The horn should respond to touching it with a bare hand. The touch command goes along the loop wire to the Osshii5 controller and Otsevi 2. The bell itself must be disconnected from the fire extinguisher for ease of transportation and storage.

The electronic accessories of the fire extinguisher module consist of: - holder for the right controller Osshi5 Otsevi 2, - mount for installing the controller, which acts as a transmitter of commands on the MK-helmet and a position marker; the controller and the fire extinguisher are connected by a loop wire through a connector in the middle of the wire - a removable bell, in which a touch sensor is mounted for registering touches with bare hands that the student can make during training; there is a special sound effect switch on the inner wall of the cut; the acoustic system can be mounted both in the bell and in the body of the fire extinguisher itself, - an acoustic accompaniment mounted in the bell or the body of the fire extinguisher, - an acoustic system that emits the sound of the fire extinguisher when the trigger is pressed, - a block for two AA batteries (1.5 m), fixed on the case under the controller holder.

Performs the role of power supply for all electronic fire extinguisher systems.

The "SIM" hardware and software complex for training and consolidating fire extinguisher handling skills includes a fire extinguisher dummy with a built-in module connected to an information processing unit (server) and a system for displaying information on the screen and consists of hardware and software: - Mega Otsevzi 2 - MK-helmet set, which is the basis of the system. Consists of MK-helmet and two controllers (left and right); - fire extinguisher module - VVK-3.5 fire extinguisher dummy for practicing skills and interactive interaction. A right controller is attached to the dummy, which will transmit all telemetry and the position of the fire extinguisher to the Meia Otsevi 2. The fire extinguisher responds to pressing the trigger and bare hand contact with the bell. The electronic equipment of the fire extinguisher communicates with the controller through a loop; - NOMI adapter Soodie Spgotesavzi NO or 4K - Broadcast image to TV or any display with NOMI input. The adapter needs an external power supply to the ZV-port 5M 1.5A; - controller - control and input device for Meia Ocevi 2; - Mi-Ri router - a device for organizing a wireless UmMi-Ri network and providing connected subscriber devices with access to the "Internet" network.

Auxiliary hardware includes: - M/-Ri-access point - perhaps the MK-helmet will not be able to directly (for example, with the help of UMi-RI rigs) see the Ssoodie Spgotesavi adapter, so it will be necessary to organize the M/-Ri-network to which these devices must be connected. If SIM-3 is deployed in a place where there is a UMi-Ri access point with good coverage, this is not a problem. And if there is no such network in the room, you will need a modern smartphone with the function of distributing the Internet via UmMi-Ri or a mobile-stationary Umi-Ri router. The selected device should be in close range of Meia Ocevi 2 and Soodie Spgotesavi during operation of "SYM-3". It is advisable to keep the mobile access point connected to the charging unit.

It is also desirable that the M/i-Ri access point works in the UMi-Gi 5 standard (802.11ac), since the standard Umi-Ri (802.11B/d/p) is overloaded in most cases in crowded places and offices. This can negatively affect the stability of the connection and delays in the broadcast of the video stream on Soodie Spgotesava.

The smartphone provides auxiliary function control and management of the Meia MK-helmet

Ocezi 2 is implemented through the Meia Ocezi mobile application. It can be installed on a smartphone based on Apagoii or 05. The application allows you to monitor the battery level of Meia devices

Otsevi 2 and it is more convenient to turn on the broadcast on Soodie Spgotesava.

The software includes: - Meia Oievi 2 - General name of the product, MK solution from the Meia company, - application "SYM-3" - installed on Meia Otsevi 2, an application that is a program for extinguishing various types of fires in the format of an interactive ZO, - Soodie Sptotesabi - the general name of the product, the Soodie company's solution for transferring content from mobile devices to a large TV screen via the UMi-RI wireless network.

The "SYM-3" application is a simulator program for extinguishing various types of fires in the format of an interactive ZO, with conditional sources of ignition: office; car workshop; kitchen: electric switchboard.

A virtual reality headset when simulating a fire includes the ability to turn on the wind, which should interact with the jet of the fire extinguisher. The wind can be in the following directions (Fig. 2): - tail wind (from the student's position to the center of the fire) - does not give any interaction with the jet; - perpendicular wind (from the left or right) - gradually deflects - the jet at an angle of 20" in the direction of the wind at a distance of 1-1.5 m, as shown in Fig. 2 below. - oncoming wind (from the center of the fire to the position of the student) - visually does not give no interaction with the jet, but there is a logical condition:

If extinguishing was started in a 30" zone in each direction relative to the line between the direction of the wind and the center of the fire, in detail in Fig. 3, where:

Fire extinguisher B1 is placed almost in a straight line between the direction of the wind and the source of the fire. When extinguishing starts in this zone, the student will receive an error.

Fire extinguisher B2 is located behind the intersection of the wind direction and the fire source. Extinguishing in this area is permitted according to fire safety regulations

The virtual reality headset for simulating a fire includes the ability to choose a fire extinguisher from several types of fire extinguishers - C types and C variants of containers.

Since there is one controller on the model of the VVK-3 fire extinguisher (which will be used tactilely by the students), the system will see the fire extinguisher as a monolithic object, and the implementation of a spray nozzle on a long hose is impossible.

Therefore, fire extinguishers of larger capacities will be displayed by models of smaller types. In models where there is a hose, it can be made short and straight.

Types of fire extinguishers are shown in Table 1

Table 1

Characteristics of fire extinguishers displayed in the hardware and software complex for training and consolidating fire extinguisher handling skills

VVK (carbon dioxide fire extinguisher) - sprays a thick white stream of carbon dioxide foam from the nozzle with an emission angle of 30". When in contact with the surface, it covers everything with frost and snow.

Visually, in the simulator, the surface touched by the jet should be covered with white traces of foam.

VP (powder fire extinguisher) - sprays a thick white jet of powder from the nozzle on the hose with an emission angle of 60". Visually in the simulator, the surface touched by the jet should be covered with white traces of powder.

VP (water fire extinguisher) - sprays water vapor from the nozzle with an emission angle of 60". Upon contact with the surface, it makes it wet. Visually in the simulator, the surface touched by the jet should be covered with a wet sheen of water vapor.

When extinguishing with all fire extinguishers, it should be accompanied by a slight emission of gray vapor from the source of ignition.

The application is controlled by the left controller using the analog stick (photo in Fig. 4) and the X and M keys, which is illustrated in Fig. 5. The analog drain must be triggered from a slope greater than 50 95, that is, have a dead zone of half the working zone. This will prevent false starts and extend the operating time after the appearance of light-medium backlash of drains

The claimed utility model is a "SIM" hardware and software complex for teaching and consolidating skills in handling a fire extinguisher (primary means of fire extinguishing) during the simulation of extinguishing fires of different 4 classes of fires. This complex was created as a further development of the previous versions of the "SYM-1" and "SYM-2" complexes, taking into account the experience gained, eliminating shortcomings and adding new ideas on a new hardware basis.

The hardware and software complex "SIM" has several iterations of development from "SIM-1" to "SIM-3". "SYM-2" differed from "SYM-1" by a complete transition to the virtual reality format, which significantly deepens the effect of presence and gives students a completely new experience. "SYM-3" is a further evolutionary development of "SYM-2" and has differences in design, convenience and cost optimization.

The "SYM-2" hardware and software complex is based on the connection: MA-helmet (Meia Osshiv5 Vii

CM) and a computing module, which is a powerful gaming laptop. The software part is calculated and visualized on a laptop. Then the image in stereo format is transmitted by

From the cable to the MA-helmet. The MA-helmet has a number of sensors and communication with controllers, the data from them are transmitted via feedback via a cable back to the laptop, for processing by the "SYM-3" program. Also, complete sensors are placed on the table with the laptop at a certain distance to track the position of the helmet and controllers. To deploy the entire system, a table with a width of at least 1 m is required.

The "SYM-3" hardware and software complex is based on a new version of the MV-helmet (Meia Osshtsiv5

Osgezi 2). The helmet is a completely mobile device, has its own power supply, computing equipment with its own operating system and a specially adapted version of the SIM-3 program on board. The system no longer requires an expensive gaming laptop. Everything works directly in the MA helmet itself. Also, you no longer need to place the sensors on the table opposite. The picture from the helmet can be broadcast via M/I to the screen of a computer, laptop, smart TV or Soodie Spgote set-top box.

The "SIM" complex is relatively easy to deploy and configure by any person without special technical knowledge who will act as an operator accompanying the student.

Navigation and scenario selection in the program is performed by the operator with the left controller. Also, the "SIM" complex has the ability to broadcast the picture to an external TV.
