SELF-RESCUER SIMULATOR FOR MINING INDUSTRY Russian patent published in 2024 - IPC A63B23/18 G09B9/00 A62B7/00 

FIELD: training models or simulators.

SUBSTANCE: invention relates to training models or simulators, in particular to life-saving breathing apparatus simulators, as well as to training devices specifically designed to improve respiratory function. Self-rescuer simulator for the mining industry includes a self-contained breathing apparatus, a subsystem for assessing the state of a trainee, a subsystem for calculating physical loads and visual representation of space. Self-contained breathing apparatus consists of a front part, a cartridge, a breathing bag, a corrugated tube, a heating element and a control module. Control module regulates the breathing resistance and distribution of gas flows from the atmosphere and the breathing bag and maintains the breathing parameters. Subsystem for assessing the state of the trainee consists of sensors of blood pressure, pulse frequency, temperature, registration of pneumotachograms and a first processor. First processor is configured to process the data on the physiological state of the user recorded by the sensors of the subsystem for evaluating the state of the trainee. Subsystem for calculating physical loads and visual representation of space consists of a user interaction module, a visualization module, a sound module and a second processor. User interaction module includes a treadmill, a mouse and a joystick. Visualization module includes a panoramic screen and virtual reality glasses. Second processor forms virtual reality and maintains its normal functioning using a sound module for input and output of audio signals. Visualization module is used for realistic display of the calculated scenes with the possibility of simulating emergency situations, explosions and fires, presentation of the main processes occurring in self-contained breathing apparatus during their operation. Hollow cartridge of the self-contained breathing apparatus comprises a rigidly fixed all-metal gas mixer with one inlet solenoid valve and two outlet solenoid valves. Inlet solenoid valve is connected to inner end of corrugated tube to provide flows of inhaled and exhaled air. Outer end of the corrugated tube is located in the front part of the self-contained breathing apparatus and is equipped with a mouthpiece. Connection between mouthpiece and corrugated tube is tight, but quick-detachable. First air quality sensor is located inside the corrugated tube. First outlet solenoid valve is connected by means of a flexible sealed air hose to a breathing bag. Breathing bag is equipped with a safety relief valve. Second outlet solenoid valve is connected by means of a flexible sealed air hose and a first inlet of a pneumatic T-joint to a two-way electric air pump rigidly fixed inside the hollow cartridge, which by means of a flexible sealed air hose is connected to a branch pipe protruding from the front part of the self-contained breathing apparatus for suction of atmospheric air and removal of part of the waste air. Second input of the pneumatic T-joint is connected to the internal air intake by means of a flexible sealed air hose. Internal air intake comprises an electromagnetic valve, as well as a second air quality sensor and provides for air replacement inside the hollow cartridge. Matrix of Peltier elements is mounted inside hollow cartridge on outer surface of all-metal gas mixer. Heat-conducting paste fills the space between the outer surface of the gas mixer and the matrix of Peltier elements. Control module of the self-contained breathing apparatus is connected to the matrix of Peltier elements by means of an electric signal switch. In order to switch from the cooling element mode to the heating element mode, the possibility of reversing the polarity of the matrix of Peltier elements is provided. All solenoid valves of gas mixer and air intake, air pump, first and second air quality sensors are electrically connected to control module. Module for interaction with the user of the subsystem for calculating physical loads and visual representation of space contains a virtual reality tracker for interactive change of the displayed scenes.

EFFECT: increasing the efficiency of use by reducing the time it takes to return the self-rescuer simulator to its original state.
