An image capture device refers to a video camera. The image capturing device, in this case a video camera, is located in such a way as to continuously receive real-time video data from the control zone in which a person or several people are located. Computer systems are understood as any computing systems built on the basis of software and hardware interconnected technical means. The data processing device can be a processor, microprocessor, graphics processor, computer (electronic computer), PLC (programmable logic controller) or an integrated circuit configured to execute certain commands (instructions, programs) for data processing. The memory device configured for data storage can be, but is not limited to, hard disk drives (HDD), flash memory, server, ROM (Read Only Memory), Solid State Drives (SSD), optical storage media, etc. . Image capture devices continuously receive video data in real time, which are recorded in the system archive (to enable further analysis on archived data), and also transmitted to the data processing device.

The disadvantage of the above invention is the functional limitation due to the impossibility of using it for gas and smoke protection service, since it cannot function in conditions of limited visibility caused by strong environmental smoke, as well as at elevated temperatures inside the object and does not have moisture protection.

The principle of operation of the proposed hardware-software complex for gas and smoke protection is as follows.

Gas and smoke protectors put on personal protective equipment (PPE), a breathing apparatus with compressed air (DASV), equipped with the inventive hardware and software complex for a gas and smoke protector with a radio wave transmitter 1.

The gas and smoke protector turns on the toggle switch of the proposed complex, after which the system boots (the program starts). Chassis 2 is equipped with I/O ports for connecting display device 3.

After turning on the proposed complex, the computing unit 4 (with a Wi-Fi transmitter), made with a power source 5 and with the ability to exchange information with an information display device 3 and a gesture recognition device 6, begins collecting information from pressure sensors 7 with radio modules, a gas analyzer 8, a heart rate monitor (not shown in figure 1), temperature sensors (not shown in figure 1), receiving a video stream from at least one video camera 9 or thermal imager 10. The computing unit 4 is made with a cooling system built into the breathing mixture supply system. The hardware-software complex for the gas and smoke protector may contain a Wi-Fi signal repeater 11 to increase the communication range.

At the same time, by means of the vertical course device 12, located in the housing 2 for fastening technological equipment, or in the gesture recognition device 6 (for example, made in the form of a wrist bracelet), the complex monitors the position of the gas and smoke protector in space and its route by changing its trajectory in space and transmits information to the computing unit 4 via a radio signal or a wired connection.

The gesture recognition device 6 is designed to transmit commands from the gas and smoke protector to the computing unit 4 and is equipped with a gyroscope to track the positioning of the device in order to work more accurately and determine the position of the hand.

Computing unit 4 information processing is made with the ability to recognize objects that captures the video camera 9 due to the software.

The computing unit 4 processes data received from pressure sensors 7 with radio modules, gas analyzer 8, at least one video camera 9 and/or thermal imager 10 using a neural network, and determines objects and obstacles in front of the gas and smoke protector, outputs information to an information display device 3 equipped with prismatic lenses 13, designed to expand the field of view of the gas and smoke protector. The hardware-software complex for the gas and smoke protector can be configured to voice control the system through a microphone 14 connected to the computing unit. In this case, the information display device 3 is a projector 15 that projects an image onto prismatic lenses 13.

Previously, the neural network is trained to recognize objects and images according to the principle of "measure of weights". After training, the neural network can determine the location of victims and fires based on information about the temperature of objects and the environment coming from the thermal imager 10.

At the same time, information is being transmitted (via wi-fi or via radio channel) to the sentry to the security post, located outside the zone unsuitable for breathing. The safety of the gas and smoke protector is ensured due to the fact that the claimed complex informs it about critical parameters, for example, about the threshold ambient temperature, about the remaining air (breathing mixture) in the cylinder, about the approach of a dangerous object. Warning video signals are output to the information display device 3 for warning.

Information about the consumption of the respiratory mixture by the gas and smoke protector, transmitted to the computing unit 4 from the pressure sensor 7 installed in the breathing apparatus, is processed with the help of software taking into account the consumption of the respiratory mixture by the gas and smoke protector, individually calculating the actual operating time depending on the level of physical activity and other known parameters.

The use of 3 prismatic lenses 13 in the complex of the information display device, on which the image is projected at an angle, allows the gas and smoke protector to see the environment due to the fact that the transparent lens does not limit its field of view. The hardware-software complex for the gas and smoke protector is configured to project onto a prismatic object by using a projector 14 built into the information display device 3. A gesture recognition device 6, a gas analyzer 8, a thermal imager 10, and a microphone 14 contain radio modules.

Thus, the claimed hardware-software complex for a gas and smoke protector allows you to collect and process information to improve the perception and identification of threats by a gas and smoke protector, as well as to formalize and automate the process of identifying threats and confirming previously identified threats in a dynamically changing environment in conditions of collapse, blockages, leaks of hazardous substances , destruction of technological equipment, limited visibility, fires, accidents.
