Description

Technical Field

[0001] This invention relates to the field of system performance research and testing equipment, and in particular to an experimental platform for testing the performance of a gas telemetry system in a typical demolition and rescue scenario. Background Technology

[0002] Following a disaster, the potential leakage of toxic and hazardous gases in the affected area poses a serious threat to the lives of personnel on site. Therefore, timely, accurate, and safe detection of gas concentrations in the area is a crucial task before rescue operations commence. However, the on-site rescue environment is characterized by its suddenness, complexity, variability, and harshness. For instance, changes in environmental parameters such as the scattering and absorption of aerosol particles and the absorption and scattering of powders significantly impact the beam transmission attenuation during laser gas detection, reducing the accuracy and reliability of laser gas measurements. Therefore, there is an urgent need to develop a performance testing platform for a gas telemetry system in typical demolition and rescue scenarios, providing a theoretical basis for improving the performance of gas telemetry systems.

[0003] However, existing simulated environment experimental platforms suffer from insufficient environmental complexity and poor stability, making it difficult to effectively reproduce diverse parameters such as temperature, humidity, and dust concentration at disaster sites in simulated environments. They also lack dynamic adjustment capabilities, which may lead to insufficient representativeness and accuracy of test results. Furthermore, the stability of the simulated environment is insufficient, and existing equipment has limited ability to control the stability of the experimental environment, making it susceptible to external interference, which in turn affects the accuracy of laser detection. Summary of the Invention

[0004] To overcome the above technical problems, the purpose of this invention is to provide a performance testing platform for a gas telemetry system in typical demolition and rescue scenarios. This testing platform simulates the ground environment after a disaster and can change environmental factors such as water mist concentration, haze concentration, smoke and dust concentration, and air temperature as needed, providing experimental conditions for the study of laser gas detection systems in rescue environments.

[0005] The technical solution adopted in this invention is:

[0006] An experimental platform for testing the performance of a gas telemetry system for typical demolition and rescue scenarios includes an experimental platform base 21, an environmental condition generation module 22, an environmental condition testing module 23, an exhaust gas treatment module 24, and a data processing module 25.

[0007] The environmental condition generation module 22 is used to simulate various environmental factors in typical demolition and rescue scenarios in situ.

[0008] It effectively recreates the temperature, humidity, dust concentration, and gas composition in a rescue scenario, thus providing a realistic experimental environment for testing the performance of a gas telemetry system;

[0009] The environmental condition testing module 23 is used to monitor various environmental parameters inside the environmental simulation chamber to verify whether the experimental environment meets the requirements of a typical demolition and rescue scenario, ensure that the experimental environmental conditions are consistent with the expected settings, and provide accurate environmental status records for subsequent data analysis.

[0010] The exhaust gas treatment module 24 is used to ensure that the experimental environment conditions are consistent with the expected settings and to provide accurate environmental status records for subsequent data analysis, ensuring the safety and environmental protection of experimental operations and protecting experimental personnel and the surrounding environment from pollution.

[0011] The data processing module 25 is used to record and analyze the environmental and detection data collected during the experiment, evaluate the actual performance of the gas telemetry system in the simulated rescue scenario, provide a basis for system optimization, and also realize dynamic feedback control of environmental conditions.

[0012] Among them, the environmental condition generation module 22, the environmental condition testing module 23, and the data processing module 25 form a closed-loop control system. While the environmental condition generation module 22 simulates typical demolition and rescue environmental conditions, the environmental condition testing module 23 and the data processing module 25 monitor and dynamically adjust the environmental simulation parameters in real time. Through the mutual control and adjustment of the above three modules, the simulated environment is ensured to meet the experimental test conditions.

[0013] The environmental condition generation module 22 simulates typical demolition and rescue scenarios, providing specific experimental conditions such as temperature, humidity, and dust concentration. The environmental condition testing module 23 monitors these environmental parameters in real time and feeds the data back to the data processing module 25 to ensure that the experimental environment meets the expected requirements. The data processing module 25 analyzes and processes the experimental data and dynamically controls the experimental environment by adjusting the environmental condition generation module 22. The waste gas treatment module 24 is responsible for purifying the harmful waste gas generated during the experiment, ensuring the safety of the experimental personnel and the cleanliness and stability of the environment. Through the coordinated cooperation of these modules, the experimental platform can accurately simulate complex rescue scenarios and monitor and adjust the experimental environment in real time.

[0014] The test bench base 21 includes an air-floating optical platform 1, a constant temperature sleeve 2, an environmental simulation warehouse 3, and a support column 10.

[0015] The constant temperature sleeve 2 is located on the upper surface of the air-floating optical platform 1, and the environmental simulation warehouse 3 is located inside the constant temperature sleeve 2; the external shape of the constant temperature sleeve 2 and the temperature and humidity sensing terminal 4 are both cuboids with square cross-sections.

[0016] Four support columns 10 are evenly arranged below the bottom along the length of the thermostatic sleeve 2. Each support column 10 has a rectangular cross-section with dimensions of 0.2 × 0.1 × 0.1 m (length × width × height) to ensure sufficient load-bearing capacity. One support column 10 is placed at each of the front and rear ends, and two more support columns 10 are equidistantly arranged in the middle. This layout effectively distributes the weight of the thermostatic sleeve 2 and the environmental simulation warehouse 4, enhancing the overall structural stability.

[0017] The environmental condition generation module 22 includes a constant temperature air supply duct 13, an air supply duct 12, a fan 11, a powder particle processing device 9, a humidifier 8, and multiple sets of air distribution systems 6.

[0018] The fan 11 is located on the air inlet side of the constant temperature sleeve 2. The fan 11 is connected to the air supply pipe 12, which delivers airflow to the system. The air supply pipe 12 connects the fan 11 and the environmental simulation chamber 3, delivering the airflow generated by the fan 11 and introducing it into the environmental simulation warehouse 3.

[0019] The constant temperature air supply duct 13 overlaps with the air supply duct 12. The constant temperature air supply duct 13 is used to maintain a constant temperature in the environmental simulation chamber 3. The constant temperature air supply duct 13 delivers airflow, which then enters the constant temperature sleeve 2.

[0020] A powder particle processing device 9 is placed on the upper surface of the air-float optical platform 1 to process powder particles and separate the mixed particulate components in the airflow. A humidifier 8 is placed adjacent to the powder particle processing device 9 to increase the humidity in the airflow and ensure that the humidity conditions of the experimental gas meet the experimental requirements. A multi-group gas distribution system 6 is located on the air-float optical platform 1 at the end of the thermostatic sleeve 2, and is used to control and adjust the various components of the airflow to meet the multi-component requirements of the experiment.

[0021] The constant temperature air supply duct 13 restores the ambient temperature conditions, the powder particle processing device 9 simulates the dust concentration information in the channel of the simulated environment warehouse 3, the humidifier 8 simulates the ambient humidity conditions of the simulated environment warehouse 3, and the multi-group gas distribution system 6 simulates the gas conditions of a typical demolition and rescue scenario in the simulated environment warehouse 3.

[0022] The powder particle processing device 9 is a cuboid and is mainly used for processing and distributing powder particles. The raw materials are processed into the required particle size by the built-in particle grinder, and then a vibrating screen or grading system is used to ensure that the particle size is uniform so that it can be mixed into the airflow of the environmental simulation warehouse 3.

[0023] The powder particle processing device 9 sends dust particles to the environmental simulation chamber 3 by controlling the wind speed and dust emission of the fan 11.

[0024] The humidifier 8 generates the required water mist concentration by preset humidity, and delivers it to the environmental simulation chamber 3 through the fan 11.

[0025] The multi-group gas distribution system 6 is a cuboid. The instrument contains multiple independent gas sources. Each source is connected to the main gas flow pipe through pipes and regulating valves. Through a vortex mixer, gases of different components are mixed to ensure that they are fully homogenized before entering the main experimental channel.

[0026] The environmental condition testing module 23 includes a temperature and humidity sensing terminal 4 and a dust concentration sensing terminal 5. The two terminals detect whether the temperature, humidity and dust particles meet the typical demolition and rescue environmental conditions.

[0027] The temperature and humidity sensing terminal 4 is located on the upper part of the outside of the thermostatic sleeve 2, and mainly uses the AM2302 model temperature and humidity sensor; the dust concentration sensing terminal 5 is located in the middle of the outside of the thermostatic sleeve 2, and the probe is inserted into the environmental simulation chamber 3 by drilling a hole. The model is the DustTrak II 8530 laser scattering sensor.

[0028] The exhaust gas treatment module 24 includes an exhaust gas duct 14 and an exhaust gas treatment device 7; the exhaust gas duct 14 is installed at the tail end of the environmental simulation chamber 3 and is used to connect the environmental simulation warehouse 3 and the exhaust gas treatment device 7.

[0029] The exhaust gas duct 14 is a cuboid with one side for air intake and the other side for air exhaust, and a filter screen in the middle to filter dust in the airflow.

[0030] The data processing module 25 includes a data cable 17 and a data processing terminal 16. The data processing terminal 16 records and analyzes experimental data and analyzes the performance of the gas telemetry system used in typical demolition and rescue scenarios. The data cable 17 is connected to the data processing terminal 16, and the other end is mainly connected to the temperature and humidity sensing terminal 4 and the dust concentration sensing terminal 5.

[0031] The experimental platform base 21 is used to place and fix various components for testing the performance of the gas telemetry system in typical demolition and rescue scenarios, so as to realize the in-situ simulation of the environmental conditions of typical demolition and rescue scenarios. The floating optical platform 1 has vibration isolation performance and automatic leveling function. The platform is made of high-quality magnetic stainless steel and the panel has M6 screw holes.

[0032] The floating optical platform 1 has a rectangular panel with M6 screw holes for easy fixing of the displacement stage, adjustment frame, optical components and system. The vibration isolation support is welded from steel pipes. The standard configuration pressure regulating filter valve will ensure the long-term effective operation of the air spring. The air source is supplied through a small air compressor or nitrogen cylinder, which is convenient for use in quiet environments.

[0033] The support column 10 is used to fix and support the environment simulation chamber 3 and the constant temperature sleeve 2; the environment simulation chamber 3 is made of polycarbonate and is customized into a circular chamber; the constant temperature sleeve 2 is made of aerogel insulation board.

[0034] The thermostatic sleeve 2 is rectangular in shape with a square cross-section of 0.3m on each side and a length of 1.2m. The environmental simulation chamber is a cylinder with a length of 1.4m and a diameter of 0.2m. The environmental simulation cabin 3 is located inside the thermostatic sleeve 2 and is enclosed by the thermostatic sleeve. The thermostatic sleeve provides a controlled temperature environment externally to stabilize the conditions inside the environmental simulation cabin. In the front view, the environmental simulation cabin 3 and the thermostatic sleeve 2 are coaxial or concentric, ensuring the flow and distribution of gases and particulate matter within the controlled thermostatic environment. Since the environmental simulation chamber is 0.2m longer than the thermostatic sleeve, its front and rear ends each extend 0.1m beyond the thermostatic sleeve.

[0035] The constant temperature air supply pipe 13 is set to supply constant temperature air into the constant temperature sleeve 2 according to the experimental requirements; the powder particle processing device 9 is pre-set to the particle size range of the powder particles according to the environmental conditions of typical demolition and rescue scenarios. After starting, it begins to crush and screen the target powder particles. By controlling the wind speed and dust emission of the fan 11, the dust particles are sent to the environmental simulation chamber 3.

[0036] The humidifier 8 generates the required water mist concentration by preset humidity, and delivers it to the environmental simulation chamber 3 through the fan 11;

[0037] The fan 11 adopts a distributed automated control system, including a variable speed air box 11-2, an electric regulating valve 11-1, and a precision control system 11-4. The fan 11 has a dual-channel input function, including a humidity channel 11-5 and a dust particle channel 11-3. Each dust particle channel 11-3 is controlled by the distributed automated control system to dynamically and stepwise deliver temperature, humidity, and dust particles to the environmental simulation chamber 3. The temperature and humidity sensing terminal 4 is connected to the interior of the environmental simulation chamber through a probe 18. Monitoring points 19 are arranged on the environmental simulation chamber 3. After the platform is started, the temperature and humidity inside the environmental simulation chamber 3 are monitored in real time. The dust concentration sensing terminal 5 is connected to the dust concentration sensing monitoring points inside the environmental simulation chamber 3 through the probe 18. There are a total of 7 monitoring points 19. The multi-group gas distribution system 6 provides detection gas for the target gas area in a typical demolition and rescue scenario. It pre-mixes multiple components of gas in a certain proportion and delivers them to the interior of the environmental simulation chamber through the gas conduit 15.

[0038] The dust particle channel 11-3 is an independent conveying pipe with a cylindrical shape, used to convey powder particles from the powder particle processing device to the environmental simulation chamber 3. The inner surface of the channel may be made of a smooth material to reduce particle adhesion and ensure smooth conveying of particulate matter.

[0039] The humidity channel 11-5 is also cylindrical in shape and is used to introduce humid air into the environmental simulation chamber 3. The inner wall material of the channel should have a certain degree of corrosion resistance to prevent the humid air from affecting the pipe material;

[0040] The precision control system includes a central control module that receives and processes data from various sensors (such as temperature and humidity sensors, dust concentration sensors, etc.). This module is programmed to set target parameters and automatically adjusts the outputs of each subsystem (such as humidity, temperature, particle concentration, etc.) to maintain a stable experimental environment. It primarily employs a closed-loop control method, using a feedback loop to monitor changes in experimental conditions in real time. When humidity, temperature, or particle concentration deviates from the set values, the system automatically adjusts accordingly to ensure that all experimental parameters remain within the set range.

[0041] A method for using a gas telemetry system performance testing platform for typical demolition and rescue scenarios includes the following steps;

[0042] The temperature and humidity sensing terminal 4, dust concentration sensing terminal 4, multi-group gas distribution system 6, humidifier 8, fan 11 and exhaust gas treatment device 7 are inspected, the platform power is turned on, and the experimental equipment is ensured to be in good working condition.

[0043] Before the official start, multiple sets of gas distribution systems need to be turned on to conduct an air quality baseline test;

[0044] The air quality baseline detection system primarily utilizes various gas sensor modules, such as carbon dioxide (CO2), carbon monoxide (CO), and nitrogen oxides (NO). x Sensors for hydrogen sulfide (H2S) and real-time particulate matter (such as PM2.5 and PM10) are used to monitor air quality in real time.

[0045] Confirm that there are no leaks of flammable or explosive gases or other harmful gases in the laboratory;

[0046] Set the environmental parameters required for the experiment, start the fan 11, and introduce the constant temperature sleeve 2 at the temperature set according to the performance test requirements; turn on the humidifier 8 and set the target humidity to generate the required water mist concentration;

[0047] By controlling the wind speed and dust emission, the fan 11 is started to control the dust particle concentration, and the smoke and dust concentration is adjusted to the set value in the same way; ensure that the temperature and humidity sensing terminal 4, the dust concentration sensing terminal 5 and the data processing terminal 16 are in monitoring state and start collecting and recording data in real time.

[0048] After the experiment was completed, we first confirmed that the experimental data was accurately recorded and saved by the system. We then used the collected data to evaluate the performance of the gas telemetry system under different conditions in order to analyze the experimental results.

[0049] At the end of the experiment, turn off the power to the humidifier, air conditioner, and other equipment in sequence to ensure that all equipment stops operating. Finally, clean up the site to remove any possible residue. After ventilating the simulated environment chamber for 10 minutes, turn off the fan and exhaust gas treatment device to maintain a clean, stable, and safe experimental environment within the simulated environment chamber. Finally, conduct a comprehensive safety inspection of the experimental platform.

[0050] The beneficial effects of this invention are:

[0051] This invention adopts a combination of an experimental platform base 21, an environmental condition generation module 22, an environmental condition testing module 23, an exhaust gas treatment module 24, and a data processing module 25. The environmental condition generation module 22 and the environmental condition testing module 23 realize in-situ simulation of typical demolition and rescue scenarios. The experimental platform base 21 keeps the environmental simulation chamber stable and ensures the stable performance testing of the gas telemetry system. The exhaust gas treatment module 24 realizes waste treatment and protects the experimental personnel and the surrounding environment. The data processing module 25 controls the internal conditions of the environmental simulation chamber through parameters such as temperature, humidity, and dust particles.

[0052] In actual measurement process:

[0053] 1. Simulates in situ typical demolition and rescue scenarios, including temperature, humidity, and powder particles of the same type and concentration; 2. Can mix multiple gases, such as combustible gases and toxic gases, and maintain their stability, for testing the sensitivity and accuracy of gas telemetry systems; 3. Can perform real-time dynamic and continuous measurement; 4. Can dynamically adjust environmental conditions in real time according to the data processing module to accurately detect the performance of gas telemetry systems.

[0054] 1. In-situ simulation of typical demolition and rescue scenarios, including temperature, humidity, and similar types and concentrations of powder particles:

[0055] The ambient temperature is primarily replicated through the constant-temperature air supply duct 13. Following experimental requirements, it directs airflow at a constant temperature into the constant-temperature sleeve 2, thereby maintaining a stable temperature within the environmental simulation chamber 3. The humidifier 8 simulates ambient humidity conditions. By pre-setting a target humidity level, it generates the required water mist concentration and delivers it to the environmental simulation chamber via the fan 1, precisely controlling the humidity level within the chamber. The powder particle processing device 9 simulates the type and concentration of dust particles. Based on the requirements of typical demolition and rescue scenarios, the particle size range is pre-set. Upon startup, the device crushes and filters the target powder particles and, by controlling the fan speed and dust emission, sends the dust particles into the environmental simulation chamber 3. The fan 1, in conjunction with the above equipment, delivers temperature, humidity, and dust particles to the environmental simulation chamber through the dust particle channel 11-3 and humidity channel 11-5, achieving precise control of temperature, humidity, and dust concentration.

[0056] 2. It can mix multiple gases, such as combustible gases and toxic gases, and maintain their stability, which can be used to test the sensitivity and accuracy of gas telemetry systems.

[0057] The system primarily uses a multi-group gas distribution system 6 to simulate gas conditions in typical demolition and rescue scenarios. This system contains multiple independent gas sources, each connected to the main gas flow pipe via pipelines and regulating valves. Using an internal vortex mixer, gases of different components are thoroughly mixed according to a preset ratio, and then delivered to the environmental simulation chamber 3 via gas conduit 15, ensuring the stability and accuracy of gas concentration.

[0058] 3. Capable of real-time, dynamic, and continuous measurement:

[0059] The environmental condition testing module 23 primarily utilizes temperature and humidity sensors 4 and dust concentration sensors 5. These sensors are connected via probes 18 to multiple monitoring points 19 inside the environmental simulation chamber (a total of 7 monitoring points) to monitor parameters such as temperature, humidity, and dust concentration in real time. The data processing module 25 consists of a data cable 17 and a data processing terminal 16. The data cable connects the sensors and the data processing terminal, transmitting the collected environmental data in real time. The data processing terminal records and analyzes the data collected during the experiment, enabling real-time dynamic and continuous measurement of environmental parameters.

[0060] 4. The environmental conditions can be dynamically adjusted in real time according to the data processing module to accurately detect the performance of the gas telemetry system: The precision control system 11-4 receives real-time data from the temperature and humidity sensing terminal and the dust concentration sensing terminal. Based on this data, the system automatically adjusts the wind speed of the variable speed fan 11-2 and the opening of the electric regulating valve 11-1 to control the temperature, humidity, and dust particle delivery rate. While analyzing and processing the experimental data, the data processing module 25, through linkage with the precision control system, dynamically adjusts the parameters of various subsystems (such as humidifiers, powder particle processing devices, and multi-group gas distribution systems) in the environmental condition generation module 22 based on the real-time monitored data.

[0066] Figure 1 This is a schematic diagram of the architecture of the present invention; Figure 2 This is the 3D modeling platform of the present invention; Figure 3 This is a top view of the platform of the present invention; Figure 4 This is a front view of the platform of the present invention; Figure 5 This is a schematic diagram of the fan structure of the present invention; a schematic diagram of a gas telemetry system performance testing platform for a typical demolition and rescue scenario in the present invention is shown below. Figure 1 As shown, it includes an experimental platform base 21, an environmental condition generation module 22, an environmental condition testing module 23, an exhaust gas treatment module 24, and a data processing module 25.

[0067] The experimental platform base 21 includes an air-floating optical platform 1, a constant-temperature sleeve 2, an environmental simulation warehouse 3, and a support column 10. The air-floating optical platform 1 ensures stable overall system testing, and the constant-temperature sleeve 2 maintains the ambient temperature. The material is polycarbonate, which has good heat insulation and high-temperature resistance, reducing testing errors. The environmental condition generation module 22 includes a constant-temperature air supply duct 13, an air supply duct 12, a fan 11, a powder particle processing device 9, a humidifier 8, and multiple gas distribution systems 6. The constant-temperature air supply duct 13 restores the ambient temperature conditions, the powder particle processing device 9 simulates dust concentration information in the channel, the humidifier 8 simulates ambient humidity conditions, and the multiple gas distribution systems 6 simulate on-site gas conditions.

[0068] During the simulation, the types of gases to be simulated and their target concentration ratios are first determined based on information transmitted from the field. Then, corresponding gas sources are prepared; these sources can be independent containers containing specific types of gases. The flow rate of each gas is controlled by a mass flow controller and precision regulating valves to ensure that each gas is accurately proportioned according to a preset ratio.

[0069] Furthermore, the mixed gases are transported through pipes to a cyclone mixer, a crucial mixing component that utilizes internal rotation and turbulence to ensure thorough mixing of various gas components. The design of cyclone mixers typically incorporates turbulence enhancement features to ensure uniform gas distribution before entering the main experimental channel, thereby simulating the complex gas environment in real-world conditions.

[0070] To ensure the uniformity and stability of the mixed gas, the mixed gas is delivered to the environmental simulation chamber 3 through gas conduit 15, where it is evenly distributed to simulate the real-world gas environment. Throughout the process, the system monitors the composition and concentration of the mixed gas in real time, and uses data processing module 25 and precision control system 11-4 for closed-loop control, dynamically adjusting the flow rate of each gas based on feedback to ensure accurate simulation and stable maintenance of gas conditions.

[0071] The environmental condition testing module 23 includes a temperature and humidity sensing terminal 4 and a dust concentration sensing terminal 5. These two terminals detect whether the temperature, humidity, and dust particles meet the typical demolition and rescue environmental conditions. The waste gas treatment module 24 mainly includes a waste gas duct 14 and a waste gas treatment device 7. The waste gas treatment device 7 uses a specific breathable membrane material to separate gases based on molecular size or chemical properties, and then performs deep treatment and conversion on the separated waste gas. The data processing module 24 mainly includes a data cable 17 and a data processing terminal 16. The data processing terminal 16 mainly records and analyzes experimental data, analyzes the performance of the gas telemetry system used in typical demolition and rescue scenarios, and provides ideas for optimizing the device.

[0072] In this invention, the method of use involves checking the temperature and humidity sensing terminal 4, dust concentration sensing terminal 5, multi-group gas distribution system 6, humidifier 8, fan 11, and exhaust gas treatment device 7, etc., starting the platform power supply, and ensuring that the experimental equipment is in good working condition; before officially starting, the multi-group gas distribution system 6 also needs to be turned on to conduct an air quality baseline test to confirm that there are no flammable or explosive gas leaks or other harmful gases in the laboratory. Set the required environmental parameters for the experiment, start the fan 11, and introduce the gas into the thermostatic sleeve 2 at the temperature set according to the performance test requirements; turn on the humidifier 8 and set the target humidity to generate the required water mist concentration; control the dust concentration by starting the fan 11 and adjusting the dust concentration to the set value in the same way by controlling the wind speed and dust emission; ensure that the temperature and humidity sensor terminal 4, dust concentration sensor terminal 5, and data processing terminal 16 are in monitoring mode and start collecting and recording data in real time; after the experiment, first confirm that the experimental data has been accurately recorded and saved by the system, and use the collected data to evaluate the performance of the gas telemetry system under different conditions to analyze the experimental results; at the end of the experiment, turn off the power to the humidifier, air conditioner, and other equipment in sequence to ensure that all equipment stops operating; finally, clean up the site, remove all possible residues, ventilate the simulated environment chamber for 10 minutes, and then turn off the fan and exhaust gas treatment device to maintain the cleanliness, stability, and safety of the experimental environment in the simulated environment chamber. Finally, conduct a comprehensive safety inspection of the experimental platform;

[0073] In this invention, the experimental platform base 21 is used to place and fix various components for testing the performance of a gas telemetry system used in typical demolition and rescue scenarios, including an air-floating optical platform 1, a constant-temperature sleeve 2, an environmental simulation chamber 3, and a support column 4, to achieve in-situ simulation of environmental conditions in typical demolition and rescue scenarios. The air-floating optical platform 1 has vibration isolation performance and automatic leveling function. The platform is made of high-quality magnetic stainless steel, and the panel has M6 screw holes to fix the displacement stage, adjustment frame, optical components, and system, so as to achieve stable emission of detection laser by the gas telemetry system in typical demolition and rescue scenarios, avoid laser deviation, and reduce experimental errors. The support column 10 uses M6 nuts to fix and support the environmental simulation chamber and the constant-temperature sleeve. The environmental simulation chamber 3 is made of polycarbonate and is customized into a circular chamber. The constant-temperature sleeve 2 is made of aerogel insulation board material, which provides extremely high thermal insulation performance and reduces the impact of external temperature fluctuations on the environmental simulation chamber.

[0074] In this invention, the environmental condition generation module 22 includes a constant temperature air supply duct 13, an air supply duct 12, a fan 11, a powder particle handling device 9, a humidifier 8, and multiple sets of air distribution systems 6, used for in-situ simulation of typical demolition and rescue scenarios; the fan 11 system includes a variable speed air box 11-2, an electric regulating valve 11-1, and a precision control system 11-4, forming a distributed automated control system with dual-channel input function, mainly including a humidity channel 11-5 and a dust particle channel 11-3. Each channel independently controls the humidity and powder particles in the air. Through the electric regulating valve 11-1 and the precision control system 11-4, the variable speed air box 11-2 coarsely and finely adjusts the air volume and wind speed of the two channels to achieve the required environmental conditions. The control system utilizes sensor feedback data. The system automatically adjusts the fan speed and valve opening to ensure the internal environment of the environmental simulation chamber meets predetermined temperature, humidity, and dust concentration, providing accurate environmental simulation for the performance testing of the gas telemetry system. The powder particle processing device 9 is used as a dust simulation device, generating and maintaining dust particles of a certain concentration and size through a specific dust generator. The particle size range is preset according to the environmental conditions of typical demolition and rescue scenarios. After startup, it begins to crush and screen the target powder particles. By controlling the wind speed and dust emission of the fan 11, the dust particles are sent to the environmental simulation chamber. The humidifier 8 is preset with humidity and generates the required water mist concentration through high-frequency vibration. At the same time, the vibration frequency or the power of the vibrating plate can be adjusted to change the water mist output. The target water mist concentration is delivered to the environmental simulation chamber through the fan.

[0075] In this invention, the environmental condition testing module 23 is used to monitor the internal environmental conditions of the environmental simulation chamber. It includes a temperature and humidity sensing module 4, a dust concentration sensing terminal 5, and multiple gas distribution systems 6. The module dynamically adjusts the internal environmental conditions of the environmental simulation chamber in real time based on the displays on each terminal. The temperature and humidity sensing terminal 4 is connected to the interior of the environmental simulation chamber via probe 18. There are seven monitoring points 19, each equipped with a high-precision temperature and humidity sensor to collect temperature and humidity data at its location in real time. The probe 18 is connected to the monitoring points 19 via cable 20, transmitting the data to the temperature and humidity sensing terminal through the probe. The dust concentration sensing terminal 5 is connected to the dust concentration sensing and monitoring points inside the environmental simulation chamber via the probe 18. There are a total of 7 monitoring points 19, and their working principle is the same as that of the temperature and humidity sensing terminal. The multi-group gas distribution system 6 provides detection gas for the target gas area in a typical demolition and rescue scenario. By connecting multiple gas supply sources, the flow rate of each gas is precisely adjusted by a mass flow controller. The multi-component gases are mixed in a certain proportion in advance and transported to the interior of the environmental simulation chamber through the gas conduit 14. The difference between the preset target gas concentration and the detection gas concentration is used as one of the performance evaluation indicators of the gas telemetry system.

[0076] To more clearly illustrate the present invention, the following description is provided in conjunction with specific embodiments:

[0077] In this embodiment, the experimental system of the present invention simulates the complex gas environment in a typical demolition and rescue scenario. Through the coordinated operation of the environmental condition generation module, environmental condition testing module, and data processing module, precise control and monitoring of the gas environment are achieved. The data processing module analyzes and processes experimental data, dynamically controlling the experimental environment by adjusting the environmental condition generation module. The waste gas treatment module is responsible for purifying the harmful waste gases generated during the experiment, ensuring the safety of experimental personnel and the cleanliness and stability of the environment. The entire experimental platform includes an experimental platform base, an environmental condition generation module, an environmental condition testing module, a waste gas treatment module, and a data processing module. These modules are organically combined to jointly achieve the goal of the simulation experiment.

[0078] In this embodiment, the environmental condition generation module simulates the gas, temperature, humidity, and dust environment in the experiment. The constant-temperature air supply duct and fan system in the module are used to deliver constant-temperature airflow into the constant-temperature sleeve to maintain a constant temperature within the environmental simulation chamber. The fan consists of a variable-speed airbox, an electric regulating valve, and a precision control system, featuring dual-channel input functionality to separately control the humidity and dust concentration in the air. The precision control system automatically adjusts the fan speed and valve opening based on feedback data to achieve the preset experimental environmental conditions. The powder particle processing device simulates the dust environment on-site by generating and maintaining dust particles of a certain concentration and size. The humidifier generates water mist through high-frequency vibration, controlling the concentration of the water mist by adjusting the vibration frequency or power, and then delivers it to the simulation chamber to ensure that the humidity of the environment meets the preset requirements. The multi-group gas distribution system simulates different gas conditions. This system contains multiple independent gas sources, each with its flow rate controlled by a mass flow controller and regulating valves, and is thoroughly mixed by a cyclone mixer to achieve the required experimental gas ratio.

[0079] In this embodiment, before the experiment begins, all sensing terminals and subsystems are checked to ensure they are in normal working order. Then, the platform power is turned on, and an air quality baseline test is performed to ensure there are no flammable, explosive, or other harmful gases in the laboratory. During the actual experiment, the environmental condition generation module activates the fan and humidifier according to preset temperature, humidity, and dust concentration conditions, channeling constant-temperature airflow into the constant-temperature sleeve. The humidifier generates water mist at the target humidity and sends it into the environmental simulation chamber. Simultaneously, the powder particle processing device controls the fan speed and dust emission rate to transport dust particles to the environmental simulation chamber, achieving the required dust concentration. Multi-component gases are transported through pipelines to a cyclone mixer to ensure uniform mixing of different gas components before entering the environmental simulation chamber.

[0080] In this embodiment, during the experiment, the data processing module analyzes the collected experimental data in real time and uses a closed-loop control system to ensure the stability of each parameter. When deviations are detected in temperature, humidity, or dust concentration, the system automatically adjusts based on feedback data to maintain the accuracy and stability of the experimental conditions. Multi-component gases from the environment are transported to the environmental simulation chamber via pipelines. The system controls the flow rate of each gas and mixes them proportionally using a mass flow controller to ensure that the concentrations of different gases in the environment meet the experimental requirements. Furthermore, closed-loop control using the data processing module and a precision control system dynamically adjusts the flow rate to ensure the stability of gas composition and concentration.

[0081] In this embodiment, after the experiment, the humidifier, fan, and other subsystems were sequentially shut down. The exhaust gas treatment module thoroughly treated the exhaust gas generated during the experiment to ensure no harmful gases remained. A comprehensive safety check was conducted on the experimental platform to ensure all equipment was switched off. After ventilating the simulated chamber for ten minutes, the fan was turned off to ensure cleanliness and safety within the chamber. Ultimately, through the coordinated operation and precise control of these modules, the experimental platform achieved accurate simulation of the gas environment in a typical demolition and rescue scenario. This successfully provided a realistic and stable testing environment for the gas telemetry system, thereby verifying its performance and providing data support for its optimization.
