Description

Technical Field

[0001] The present invention relates to the technical field of system performance research and test devices, and particularly to an experimental platform for testing the performance of a gas telemetry system for typical demolition and rescue scenarios. Background Art

[0002] After a disaster occurs, the toxic and harmful gases that may leak in the affected area pose a serious threat to the lives of the people at the scene. Therefore, timely, accurate, and safe detection of the gas concentration in the area is an important task before the rescue. However, the on-site rescue environment has characteristics such as suddenness, complexity, variability, and harshness. For example, changes in environmental parameters such as the scattering and absorption of aerosol particles at the scene and the absorption and scattering of powders have a significant impact on the attenuation of the beam transmission during the laser gas detection process, reducing the accuracy and reliability of the laser gas measurement. Therefore, there is an urgent need to invent an experimental platform for testing the performance of a gas telemetry system for typical demolition and rescue scenarios to provide a theoretical basis for improving the performance of the gas telemetry system.

[0003] However, the existing simulation environment experimental platform has insufficient environmental complexity and poor stability. It is difficult to effectively restore diverse parameters such as temperature, humidity, and dust concentration in the disaster scene in the simulation environment, lacks dynamic adjustment capabilities, may lead to insufficient representativeness and accuracy of the test results, and the stability of the simulation environment is insufficient. The existing equipment has limited stability control capabilities for the experimental environment and is easily affected by external interference, thus affecting the accuracy of laser detection. Summary of the Invention

[0004] In order to overcome the above technical problems, the purpose of the present invention is to provide an experimental platform for testing the performance of a gas telemetry system for typical demolition and rescue scenarios. The experimental platform simulates the on-site ground environment after a disaster and can change environmental factors such as the water mist concentration, haze dust concentration, smoke and dust concentration, and air temperature of the simulation experimental platform as needed, providing test conditions for the research of the laser gas detection system in the rescue environment.

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, it is ensured that the simulated environment meets the experimental test conditions;

[0013] The environmental condition generation module 22 is used to simulate typical demolition and rescue scenarios and provide 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 is used to analyze and process experimental data and dynamically control 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 to ensure the safety of experimental personnel and the cleanliness and stability of the environment.

The cross-section of each support column 10 is rectangular, with dimensions of 0.2×0.1×0.1 m (length×width×height) to ensure sufficient load-bearing capacity. One support column 10 is provided at each of the front and rear ends, and the other two support columns 10 are arranged at equal intervals in the middle part. This layout can effectively disperse the weights of the constant temperature sleeve 2 and the environmental simulation warehouse 4, enhancing the stability of the overall structure.

[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 duct 12, and the air flow is transported to the system through the air supply duct 12. The air supply duct 12 is connected to the fan 11 and the environmental simulation chamber 3, transporting the air flow 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 in position. The constant temperature air supply duct 13 is used to keep the temperature of the environmental simulation chamber 3 constant. The constant temperature air supply duct 13 transports the air flow, and then enters the constant temperature sleeve 2.

[0020] The powder particle processing device 9 is placed on the upper surface of the air-floating optical platform 1, which is used to process powder particles so as to separate the mixed particle components in the air flow. The humidifier 8 is placed adjacent to the powder particle processing device 9, which is used to increase the humidity in the air flow to ensure that the humidity condition of the experimental gas meets the experimental requirements. Multiple groups of air distribution systems 6 are located on the air-floating optical platform 1 and at the end of the constant temperature sleeve 2, which are used to control and adjust various components of the air flow to meet the multi-component requirements of the experiment.

[0022] The powder particle processing device 9 is a cuboid, mainly used for processing and distributing powder particles. The raw materials are processed into the required particle size by an internal particle grinder, and then a vibrating screen or a classification system is used to ensure that the particle size is uniform so as to mix them into the air flow of the environmental simulation warehouse 3.

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

[0024] The humidifier 8 generates the required water mist concentration based on a preset humidity and transports it to the environmental simulation chamber 3 through the blower 11.

[0025] The multi-group gas distribution system 6 is a cuboid. Inside the instrument, there are multiple independent gas sources, and each source is connected to the main air flow pipe through a pipeline and a regulating valve. Different components of gas are mixed through a swirl mixer to make them fully uniform 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 standards of a typical demolition and rescue environment condition.

[0027] The temperature and humidity sensing terminal 4 is located above the outer side of the constant temperature sleeve 2 and mainly uses a temperature and humidity sensor of model AM2302. The dust concentration sensing terminal 5 is located in the middle of the outer side of the constant temperature sleeve 2. The probe is placed into the environmental simulation chamber 3 through a hole, and the model is a laser scattering type sensor DustTrak II 8530.

[0028] The waste gas treatment module 24 includes a waste gas duct 14 and a waste gas treatment device 7. The waste 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 waste gas treatment device 7.

[0029] The waste gas duct 14 is a cuboid, with one side for air intake and the other side for air outlet. A filter screen is spaced in the middle to filter dust in the air flow.

[0030] The data processing module 25 includes a data line 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 for typical demolition and rescue scenarios. The data line 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 bench base 21 is used to place and fix various components for testing the performance of the gas telemetry system for typical demolition and rescue scenarios, realizing in-situ simulation of the environmental conditions of typical demolition and rescue scenarios. The floating optical platform 1 has vibration isolation performance and an automatic level adjustment function. The platform is customized with high-quality ferromagnetic stainless steel, and the panel has M6 screw holes.

[0032] The panel of the floating optical platform 1 is rectangular, and the panel of the floating optical platform 1 has M6 screw holes, which are easy to fix displacement stages, adjustment frames, optical elements, and systems. The vibration isolation support is welded by 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 by a small air compressor or a nitrogen cylinder, which is convenient for use in quiet occasions.

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

[0034] The overall shape of the constant temperature sleeve 2 is a cuboid, the cross-section is a square with a side length of 0.3 m, and the length is 1.2 m. The environmental simulation warehouse is a cylinder with a length of 1.4 m and a diameter of 0.2 m. The environmental simulation chamber 3 is located inside the constant temperature sleeve 2 and is wrapped by the constant temperature sleeve. The constant temperature sleeve provides a controlled temperature environment outside to stabilize the conditions inside the environmental simulation chamber. In the front view, the environmental simulation chamber 3 and the constant temperature sleeve 2 are in a coaxial or concentric position to ensure the flow and distribution of gas and particulate matter in a controlled constant temperature environment. Since the environmental simulation warehouse is 0.2 m longer than the constant temperature sleeve, its front and rear ends each extend 0.1 m beyond the constant temperature sleeve.

[0035] The constant temperature air supply duct 13 feeds the constant temperature air set according to the experimental requirements into the constant temperature sleeve 2; the powder particle processing device 9 pre-sets the powder particle size range according to the environmental conditions of typical demolition and rescue scenarios. After being started, it begins to break and screen the target powder particles, and sends the dust particles to the environmental simulation chamber 3 by controlling the wind speed and dust emission amount of the fan 11;

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

[0037] The fan 11 adopts a distributed automation 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 a distributed automation control system, and dynamically and step by step transports the temperature, humidity and dust particles to the environmental simulation chamber 3; the temperature and humidity sensing terminal 4 is connected to the inside of the environmental simulation chamber through a probe 18, and monitoring points 19 are arranged on the environmental simulation chamber 3.

[0038] The dust particle channel 11-3 is an independent conveying pipeline, in the shape of a cylinder, used to transport powder particles from the powder particle processing device to the environmental simulation chamber 3. The inner surface of the channel may adopt a smooth material to reduce particle adhesion and ensure the smooth transportation 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 certain corrosion resistance to prevent the influence of humid air on the pipeline material;

[0040] The precision control system includes a central control module for receiving and processing data from various sensors (such as temperature and humidity sensors, dust concentration sensors, etc.). This module sets target parameters through programming and automatically adjusts the outputs of each subsystem (such as humidity, temperature, particle concentration, etc.) to maintain a stable experimental environment. It mainly adopts a closed-loop control method and monitors the changes in experimental conditions in real time through a feedback loop. When it detects that the humidity, temperature, or particle concentration deviates from the set value, the system will automatically make corresponding adjustments to ensure that all experimental parameters always remain within the set range;

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

[0042] Inspect the temperature and humidity sensing terminal 4, dust concentration sensing terminal 4, multi-group gas distribution system 6, humidifier 8, fan 11, and waste gas treatment device 7, and start the platform power supply to ensure that the experimental equipment is in good working condition;

[0043] Before the formal start, it is also necessary to turn on the multi-group gas distribution system for an air quality baseline detection;

[0044] Among them, the air quality baseline detection system mainly configures a variety of gas sensor modules, such as carbon dioxide CO2, carbon monoxide CO, nitrogen oxides NO x , hydrogen sulfide H2S, and real-time detection particulate matter (such as PM2.5, PM10) sensors to detect the real-time monitored air quality;

[0045] Confirm that there is no leakage of flammable and explosive gases or other harmful gases in the laboratory;

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

[0047] By controlling the wind speed and dust emission amount, start the fan 11 to control the dust particle concentration, and adjust the concentration of smoke and dust to the set value in the same way; ensure that the temperature and humidity sensing terminal 4, dust concentration sensing terminal 5, and data processing terminal 16 are in the monitoring state, and start to collect and record data in real time;

[0048] After the experiment is completed, first confirm that the experimental data is accurately recorded and saved by the system. Use the collected data to evaluate the performance of the gas telemetry system under different conditions to analyze the experimental results;

[0049] At the end of the experiment, turn off the power of the humidifier, air conditioner and other equipment in sequence to ensure that all equipment stops running; finally, conduct on-site cleaning, remove all possible residues, ventilate the simulated environmental chamber for 10 minutes, then turn off the fan and waste gas treatment device to keep the experimental environment in the simulated environmental chamber clean, stable and safe. Finally, conduct a comprehensive safety inspection of the experimental bench.

After startup, the device breaks and screens out the target powder particles, and through controlling the wind speed of the fan and the dust emission amount, the dust particles are sent into the environmental simulation chamber 3. The fan 1 cooperates with the above-mentioned devices and transports the temperature, humidity, and dust particles to the environmental simulation chamber through the dust particle channel 11-3 and the humidity channel 11-5 to achieve precise control of the temperature, humidity, and dust concentration.

[0057] It mainly uses the multi-group gas distribution system 6 to simulate the gas conditions in typical demolition and rescue scenarios. This system contains multiple independent gas sources, and each gas source is connected to the main air flow pipe through pipelines and regulating valves. Using the internal swirl mixer, gases with different components are fully mixed in a preset ratio and then transported to the environmental simulation chamber 3 through the gas conduit 15 to ensure the stability and accuracy of the gas concentration;

[0058] 3 can perform real-time dynamic continuous measurement:

[0059] It mainly uses the temperature and humidity sensing terminal 4 and the dust concentration sensing terminal 5 in the environmental condition test module 23. These sensing terminals are connected to multiple monitoring points 19 inside the environmental simulation chamber through the probe 18. There are a total of 7 monitoring points, which can monitor parameters such as the temperature, humidity, and dust concentration in the chamber in real time. The data processing module 25 consists of a data line 17 and a data processing terminal 16.

By connecting multiple gas supply sources, the flow rate of each gas is precisely adjusted through a mass flow controller. The multi-component gases are pre-mixed in a certain proportion in advance and transported to the inside of the environmental simulation chamber through a gas conduit 14. The difference value between the preset target gas concentration and the detected gas concentration is used as one of the performance evaluation indicators of the gas telemetry system by comparative analysis.

[0076] To more clearly illustrate the present invention, the following corresponding 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 generating module, the environmental condition testing module, and the data processing module, precise control and monitoring of the gas environment are achieved. The data processing module is used to analyze and process experimental data, and dynamically control the experimental environment by adjusting the environmental condition generating module. The waste gas treatment module is responsible for purifying the harmful waste gas generated during the experiment to ensure the safety of experimental personnel and the cleanliness and stability of the environment. The entire experimental platform includes an experimental bench base, an environmental condition generating module, an environmental condition testing module, a waste gas treatment module, and a data processing module. Each module is organically combined to jointly achieve the goal of the simulation experiment.

[0078] In this embodiment, the environmental condition generating module simulates the gas, temperature and humidity, and dust environment in the experiment. The constant temperature air supply pipe and the fan system in the module are used to send the constant temperature air flow into the constant temperature sleeve to maintain the constant temperature in the environmental simulation chamber. The fan consists of a variable speed air box, an electric regulating valve, and a precision control system, and has a dual-channel input function, which can separately control the humidity and dust concentration in the air. The precision control system automatically adjusts the fan speed and valve opening through feedback data to achieve the preset experimental environmental conditions. The powder particle processing device simulates the dust environment on site by generating and maintaining a certain concentration and particle size of dust particles. The humidifier generates water mist through high-frequency vibration, controls the concentration of the water mist by adjusting the vibration frequency or power, and transports it to the simulation chamber to ensure that the humidity of the environment meets the preset requirements. The multi-component gas distribution system simulates different gas conditions. This system contains multiple independent gas sources. Each gas controls its flow rate through a mass flow controller and an adjusting valve, and is fully mixed through a swirl mixer to achieve the required experimental gas ratio.

[0079] In this embodiment, before the experiment starts, all sensing terminals and subsystems are checked to ensure that they are in a normal working state. Then the platform power supply is started, and an air quality baseline detection is carried out to ensure that there are no flammable, explosive, or other harmful gases in the laboratory. When the experiment is officially running, the environmental condition generating module starts the fan and the humidifier according to the preset temperature, humidity, and dust concentration conditions, sends the constant temperature air flow into the constant temperature sleeve, and the humidifier generates and sends the water mist with the target humidity into the environmental simulation chamber. At the same time, the powder particle processing device transports the dust particles to the environmental simulation chamber by controlling the fan speed and the dust emission amount to form a dust concentration that meets the requirements. The multi-component gas is transported to the swirl mixer through the pipeline to ensure that different gas components are evenly mixed before entering the environmental simulation chamber.

[0080] In this embodiment, during the experiment, the data processing module performs real-time analysis on the collected experimental data and uses a closed-loop control system to ensure the stability of each parameter. When deviations in temperature, humidity, or dust concentration are detected, the system automatically adjusts according to the feedback data to maintain the accuracy and stability of the experimental conditions. The multi-component gas in the environment is transported to the environmental simulation chamber through pipelines. The system controls the flow rate of each gas through a mass flow controller and mixes them in proportion to ensure that the concentration of different gases in the environment meets the experimental requirements. Moreover, a closed-loop control is performed using the data processing module and the precision control system to dynamically adjust the flow rate and ensure the stability of the gas composition and concentration;

[0081] In this embodiment, after the experiment, the humidifier, the fan, and other subsystems are turned off in sequence, and the exhaust gas treatment module thoroughly treats the exhaust gas generated during the experiment to ensure that no harmful gases remain. A comprehensive safety inspection is carried out on the experimental bench to ensure that all equipment has been turned off. After ventilating the simulation chamber for ten minutes, the fan is turned off to ensure the cleanliness and safety inside the chamber. Finally, through the mutual cooperation and precision control of these modules, the experimental platform achieves an accurate simulation of the gas environment in a typical demolition and rescue scenario, successfully provides a real and stable test environment for the gas telemetry system, thereby verifying the performance of the gas telemetry system and providing data support for its optimization.
