[0002] In recent years, the number of people employed in specialized occupations in my country has continued to increase. Workers in workplaces such as geological exploration, power transmission, chemical production, and emergency rescue operations following fires and explosions are often exposed to harsh environments, including extreme high and low temperatures, high and low air pressure, radiation, and rain or snow. These working environments not only impact worker efficiency but can also pose significant health risks in the event of long-term exposure. Furthermore, these hazards arise from the combined effects of multiple hazards under specific environmental conditions, making them complex and unpredictable.

[0003] With the comprehensive development of electronic communications, mechanical manufacturing and other fields, in order to prevent the occurrence of occupational hazards and protect the lives of workers, it is necessary to propose a new technical solution to determine the degree of hazard of various hazard factors in a disaster environment either alone or in coupling, or to evaluate the protective performance of individual protective equipment in a disaster environment, and provide scientific guidance for the pre-evaluation of occupational hazards and the improvement of individual protective equipment.

DETAILED DESCRIPTION

[0030] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0031] Example 1

[0032] The technical solution adopted in this embodiment is as follows Figures 1 to 9As shown, a coupled disaster scenario human physiological parameter analysis system in different operating states includes a coupled disaster scenario simulation system, different operating state simulation components, and a human physiological parameter acquisition and analysis system; wherein the coupled disaster scenario simulation system includes a disaster simulation cabin, a disaster scenario generation system, a disaster factor monitoring system, and a disaster control and display system, which can quantitatively control coupled disaster scenarios such as high and low temperature, hypoxia, high and low air pressure, strong wind, rain, snowfall, and fire in the simulation cabin;

When compressed, the inner rod is fixed in the outer rod through threads. When extended, the inner rod is pulled out and connected to the outer rod by the threads and screw fixing interfaces of the connecting part, so that the length, width and height of the cabin can be adjusted to simulate disasters of different sizes; the detachable walls and top plates are spliced ​​together by rectangular plates and covered on the outside of the retractable skeleton. The rectangular plates include an outer layer and an inner layer. The outer layer is SDJK insulation material and the inner layer is waterproof and fireproof gypsum plate, which improves the thermal insulation and fireproof performance of the disaster simulation cabin.

[0034] In addition, the bottom plate of the disaster simulation cabin can be a terrain simulation platform, which includes a landing surface, a strut cylinder and a driver. The landing surface can be made into various terrain undulations by adjusting the height of each strut cylinder through the driver. The driver is controlled by a computer and a programmable controller. The computer receives terrain data and proportionally reduces the coordinate data therein and sends it to the programmable controller. The programmable controller controls the opening or closing of the hydraulic oil in the strut cylinder according to the reduced data, thereby realizing the simulation of various terrains of the landing surface and meeting the needs of some special terrains.

[0035] The disaster scenario generation system includes a hot and cold air circulation system 37, a pressure pumping system 311, an oxygen control device, a rainfall system, a snowfall system, a lighting simulation system, a noise simulation system and a humidity control system.

[0036] like Figure 1As shown, the hot and cold air circulation system 37 includes an air circulation pipe, an electromagnetic switch valve, a turbine, an air-to-air heat exchanger, a water-cooled heat exchanger and an electric compressor; the cold air flow 39 flows in from the air-to-air heat exchanger port, forms a cycle through the compressor, water-cooled heat exchanger, compressor, water-cooled heat exchanger, and air-to-air heat exchanger, and flows out from the turbine port; the hot air flow 38 flows in from the turbine port, passes through the water-cooled heat exchanger, compressor, water-cooled heat exchanger, and compressor, and flows out from the air-to-air heat exchanger port; the air circulation pipe is connected to the disaster simulation cabin through the third interface 314, and is regulated by an electromagnetic switch valve.

The blower is located at the air supply duct 14 at one end of the reaction chamber, and the air supply duct 14 at the other end of the reaction chamber is connected to the disaster simulation chamber body through a second interface 313; the disaster simulation chamber is also provided with a one-way air outlet valve used in conjunction with the oxygen control device, and the one-way air outlet valve sends out the original air in the reaction chamber until the oxygen concentration in the disaster simulation chamber is reduced to a preset concentration to simulate a low oxygen environment.

[0039] The grid plate 13 is composed of thin compressed cotton plates arranged vertically. The compressed cotton component polyvinyl alcohol (PVA) has a continuous porous molecular structure and has strong absorbency and water retention. The spray device 11 is composed of multiple nozzles located above the grid plate 13, which spray ferrous sulfate solution onto the thin compressed cotton. When in use, the blower 15 and the electromagnetic switch valve installed on the pipeline are turned on. When the air flows through the grid plate 13, the oxygen contained in the air is absorbed by the ferrous sulfate solution in the thin compressed cotton. The remaining main component nitrogen flows through the compressed cotton net 19 to dry and enters the disaster simulation cabin through the second interface 313. The ferrous sulfate solution continues to flow from the nozzle to the compressed cotton through the delivery pipe. Ferrous sulfate solution is sprayed onto grid plate 13. The ferrous sulfate solution reacts with oxygen to form a solution containing trivalent iron, which then leaves the compressed cotton and flows through return pipe 17 into reduction water tank 110. The solution is reduced by the internal corrugated pure iron mesh to form a divalent iron solution. The solution is then sprayed out of the nozzle again through ferrous sulfate solution delivery pipe 12. When the color of the solution changes from blue-green to yellow, the solution and the corrugated iron mesh 18 are replaced. The solenoid valve, air supply pipe 14, ferrous sulfate solution delivery pipe 12, spray device 11, return pipe 17, liquid supply pump 16, and the interior of reduction water tank 110 are all coated with PVDF, an anti-corrosion material, to extend the service life of the device.

Specifically, a ferric sulfate solution is contained in a reduction water tank, the positive electrode of the primary cell is a graphite rod, and the negative electrode is a zinc rod, and the two electrodes are connected by a wire; the solution containing trivalent iron generated by the reaction with oxygen separates from the compressed cotton and flows through the return pipe 17 to the reduction water tank 110, where it is reduced to a divalent iron solution, which is then sprayed out of the nozzle again through the ferrous sulfate solution delivery pipe 12.

Water enters the pipe network guide pipe through the second water inlet pipe 41 and is fully mixed with the high-pressure air delivered through the high-pressure airflow delivery pipe 47 in the pressure-type atomizing nozzle 46, generating fine droplet spray and exchanging heat with the cold air to form snowfall. The second water inlet pipe 41 and the high-pressure airflow delivery pipe 47 are respectively connected to the top of the disaster simulation cabin through the fifth interface 316 and the sixth interface 317; a first electromagnetic flow switch 43 for controlling the flow rate is also provided on the pipe between the chiller 45 and the second water inlet pipe 41, and a second electromagnetic flow switch 48 for controlling the airflow flow rate is provided on the high-pressure airflow delivery pipe 47.

It is mainly used to input the type and intensity of disaster factors that need to be simulated, and transmit the signal to the disaster factor control system, as well as receive monitoring data from the disaster factor monitoring system, and display the intensity of various disaster factors in the disaster simulation cabin in real time.

[0046] The different working state simulation components include an electric climber and a treadmill and a matching resistance device located in the working activity area 36 of the disaster simulation cabin, which are used to simulate different working methods and labor intensities;

[0047] like Figure 5 and Figure 6 As shown, the electric climber includes a steel frame 516, a first drive motor 54, a second drive motor 55, an upper and lower electric drive shaft 514, an upper and lower connecting rod 52, two arc-shaped hydraulic telescopic rods 56, a safety rope 515, a ring 517, a steel bottom plate 59, a steel load-bearing plate 510, a rubber pad 511, a belt 51 with irregularly distributed stepping blocks 53, a display screen support rod 58, a display screen control panel 57, a connecting steel block 513, and a rotating shaft 512. The drive motors are connected to the upper and lower connecting rods 52 and the steel frame 516 between the upper and lower electric drive shafts 514, respectively. The first drive motor 54 and the second drive motor 55 drive the belt 51 through the upper and lower electric drive shafts 514. The upper and lower electric drive shafts 514 drive the belt 51 through two arc-shaped telescopic rods with a telescopic range of 65 degrees to 90 degrees. The hydraulic telescopic rod 56 is connected to the steel base plate 59, and the steel frame 516 is connected to the base plate through a connecting steel block 513 with a rotating shaft 512. The steel load-bearing plate 510 is welded to the lower side of the base plate to bear the weight of the electric climber. There are four rubber pads 511 on the lower side of the steel load-bearing plate 510 to reduce shock and stabilize the electric climber. The belt 51 is fixed with irregularly distributed stepping blocks 53 of appropriate size for trainees to climb. The display screen console 57 is connected to the base plate through a support rod. The operator can control the telescopic arc of the arc-shaped hydraulic telescopic rod 56 and the power of the motor through the console to control the climbing slope and climbing speed. After wearing the safety rope 515, the trainee performs climbing training at a speed relative to the downward movement of the belt 51, and adjusts the simulated climbing speed and slope according to the training intensity requirements.

[0048] like Figure 7 As shown, the treadmill 613 and the resistance device include a bottom symmetrical connecting rod 68, a symmetrical steel vertical rod 61, a pulley 65, an axle 64, a fixing hole 62, a fixing screw 612, a polyester rope 66, a rope loop / handle 63, a plug hole 69, a plug nail 67, and several steel load blocks 610 of the same mass; the bottom symmetrical connecting rod 68 is fixed to the base of the treadmill 613 by a fixing screw 612, the symmetrical steel vertical rod 61 is vertically fixed to the end of the bottom symmetrical connecting rod 68 by a connecting screw 611, the pulley 65 is fixed to the fixing hole 62 on the equally spaced steel vertical rod by the axle 64, and the pulling angle of the trainee can be adjusted by moving the height of the fixed position of the axle 64, the lower end of the polyester rope 66 is connected with a plug nail 67, and the steel The load blocks are arranged side by side on the symmetrical steel vertical rods, and the steel load blocks are movably arranged on the symmetrical steel vertical rods. Under normal circumstances, the steel load blocks are located at the lower part of the symmetrical steel vertical rods under the action of gravity. Each steel load block is provided with a plug hole 69 used in conjunction with the plug nail 67. The plug nail 67 can be inserted into the plug hole 69 on the corresponding load block according to the load size. The upper end of the polyester rope 66 is connected with a rope loop or a handle, and the rope loop or the handle can be used by trainees to simulate shoulder-carrying and hand-pulling actions during running. There are 10 steel load blocks 610 of the same mass, each with a mass of 10 kg and a plug hole 69. The tester can achieve simulation tests of different training intensities by adjusting the load weight, the pace of the treadmill 613 and the inclination height.

[0049] like Figure 8 and Figure 9 As shown, the human physiological parameter collection and analysis system includes a wearable physiological parameter collection kit, a central control monitoring unit and an analysis and display terminal. It can collect human body temperature, blood pressure, pulse, respiration, electrocardiogram and other physiological parameters in a non-invasive manner without affecting the working state and perform real-time analysis and display.

[0050] The wearable physiological parameter collection kit is a wearable tight-fitting elastic vest, which reflects the changes and frequency of the tester's chest and abdominal volume through the changes in the area of ​​the tight-fitting elastic material, and then quantifies the tester's breathing intensity under different working conditions or oxygen content; the vest is used in conjunction with a wireless sensor network, which includes wireless sensor nodes. The wireless sensor nodes include a body temperature sensor 71, a blood oxygen sensor 72, an electrocardiogram sensor 73 and a pulse sensor 74, which can realize the acquisition and preliminary processing of body temperature, blood oxygen, pulse wave, electrocardiogram and blood pressure parameters.

[0051] The body temperature sensor nodes are several data acquisition units of thermistor sensors. Since the temperature data at different positions of the human body may be different, the average value of multiple data acquisition units is taken for calculation; the A / D processing unit converts physical parameters into digital signals, and the transmission unit transmits signals and conducts two-way transmission with the central monitoring aggregation node. When the transmission unit receives the initial command from the central control monitoring unit, it starts the monitoring command. When the human body temperature changes, it will cause the changes in the thermistor characteristics and then the changes in the circuit parameters. Each body temperature measurement sensor node transmits the measured human body temperature data to the central monitoring aggregation node through a wireless module.

[0052] The blood oxygen and pulse wave measurement node includes a photoplethysmography data acquisition unit based on the Lambert-Beer law, a data processing unit, and a radio frequency signal transmission unit. When the pulse wave measurement sensor emits light of a certain wavelength onto tissue containing blood vessels, the optical path of the incident light penetrating the vessels changes due to the periodic changes in vessel diameter, causing periodic variations in the reflected light intensity. This periodic variation in light intensity reflects the heart's pulsation cycle. This cyclical variation in light intensity is detected to reflect the heart's pulsation cycle, which is then converted by the sensor into a PPG signal. The RF signal transmission unit then sends it to a central monitoring convergence point, where the pulse wave is analyzed graphically. Because blood oxygen levels can differ between the proximal and distal ends of the body, it is possible to interpolate values ​​between local arteries and veins over a specific period of time to reflect local oxygen consumption.

[0053] Similarly, when the photoelectric sensor of the blood oxygen sensor node emits incident light with wavelengths of 660 and 940 mm and passes through human tissue, the different absorption abilities of Hb and HbO2 in venous blood and arterial blood for specific incident light will lead to different outgoing light intensities. The blood oxygen content can be obtained through mathematical calculation by the processing unit and sent to the central monitoring aggregation node by the radio frequency signal transmission unit.

[0054] The ECG sensor node includes wearable ECG electrodes, a data processing unit and a radio frequency signal transmission unit. The wearable ECG electrodes are composed of an outer protective layer, a middle elastic filling layer, an inner sensing pad and a conductive connection plate; the data processing unit includes an AD620 signal amplifier, a compensation circuit, etc. Cardiac activity will produce a closed circuit action, causing current to flow in the chest volume conductor. This potential change can be measured on the body surface. The AD620 instrument amplifier with a high common-mode rejection ratio is used to detect the interference noise caused by the change in contact impedance between the wearable electrode and the skin, and the interference compensation circuit is used to suppress the common-mode interference of the electrode. The ECG signal after preliminary processing is transmitted to the central aggregation node by radio frequency communication.

[0055] Blood pressure is measured using a new cuffless blood pressure measurement method that does not require a dedicated sensor node. Instead, the blood pressure can be determined by data analysis of the obtained ECG signal and pulse wave PPG signal graph. Both systolic pressure (SBP) and diastolic pressure (DBP) can be determined by the time Pwwt from the R-wave peak of the ECG signal at the moment of cardiac contraction to the pulse wave PPG signal peak.

[0056] The central control and monitoring unit and analysis and display terminal enable real-time monitoring of human health in changing environments. The central control and monitoring unit includes a central monitoring aggregation node, a NAND flash + SDRAM processor, a data graphical display, and a remote wireless communication GPRS module. After the central control and detection unit issues a startup command to the wireless sensor network, it wirelessly transmits the control information and sampling information from the wireless sensor nodes to the central monitoring aggregation node. The aggregation node of the central control and monitoring unit receives the information from the wireless sensor network and uses the NAND flash + SDRAM processor to compress, fuse, and encapsulate the information. Finally, the processed data is sent to the analysis and display terminal via the remote wireless communication module. The communication transmission module uses the GPRS system to remotely transmit data between the central control unit and test personnel over a wireless wide area network.

[0057] Example 2

[0058] The changes in the physiological parameters of firefighters when using indoor electric climbing devices were measured in strong light, high temperature, low pressure and rainfall environments. Figure 1 The medium noise simulator, xenon lamp and humidity controller are used to set the noise decibel, light intensity and humidity parameters in the simulated environment. After the settings are completed, the temperature, rainfall and air pressure parameters are selected on the disaster factor input display device. The disaster factor control system receives signals to control the electromagnetic switch valves of the hot and cold air circulation system, pressure pumping system, oxygen control device and rainfall system. The air pressure sensor, temperature sensor and rainfall measurement sensor in the disaster simulation cabin work and feed back the measured air pressure, temperature and rainfall data to the disaster factor input display device. The disaster factor input display device automatically updates the data and the system automatically compares it with the parameter setting value. If the parameters of each hazard factor in the disaster simulation cabin do not reach the set value, they will be further adjusted until the required environmental requirements are met.

[0059] After the environment is set up, the testers enter the disaster simulation cabin while wearing physiological parameter collection suits, and conduct simulated training of the climber in the activity training area. They are divided into four levels according to the labor intensity index grading standards, and the training simulation is carried out in turn.

[0060] Before the test personnel start training, the power of the central control detection control unit is connected. The central control detection control unit issues a start command. After receiving the command, the wireless sensor node network starts monitoring and obtains initial parameters as a control. During the test personnel's indirect action simulation training at different intensity levels, the test personnel's body temperature, blood oxygen, electrocardiogram, blood pressure and pulse data are obtained in real time by wearing a vest. After receiving the information from the wireless sensor network, the aggregation node of the central monitoring control unit compresses, fuses and encapsulates the information through the NANDflash+SDRAM processor. Finally, the processed data is transmitted to the background service terminal using the GPRS communication protocol. Through the analysis of human physiological parameters, the changes in the human physiological state under the influence of the coupled catastrophic environment are determined, and the degree of harm caused by the coupled environment is quantitatively evaluated.

After knowing the contents described in the present invention, ordinary technicians in this technical field can make several equivalent changes and substitutions without departing from the principles of the present invention.
