Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a mining simulation self-rescue device. Background Technology

[0002] Mining self-rescue devices are crucial life-saving equipment for miners in emergency situations underground. Equipped with an oxygen cylinder, these devices provide oxygen to the miner in case of danger, aiding in their escape. However, existing self-rescue devices are expensive and not reusable. Therefore, current coal mine safety training programs do not allow miners to practically operate these devices, leading to difficulties in correctly and quickly donning them in dangerous situations underground, thus threatening their lives. Therefore, it is necessary to provide a simulated mining self-rescue device that miners can actually operate.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In response to the problems mentioned in the background art, this utility model proposes a mining simulation self-rescue device that is low in cost, reusable, and allows miners to actually operate the simulation self-rescue device, thereby improving miners' life safety underground.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, a mine-use simulated self-rescue device is provided. The housing includes an upper housing and a lower housing, which are detachably connected. An inner support is disposed on the lower housing and located in the inner cavity of the housing. An air duct is formed on the inner support. A first operating switch and a second operating switch are disposed on the inner support. A first fan is configured to start when the first operating switch is turned on to guide outside air into the air duct. A second fan is configured to start when the second operating switch is turned on to guide outside air into the air duct. An airbag is connected to the inner support and communicates with the air duct.

[0006] In some embodiments of this application, the inner support includes a support body and a support extension; the support body is connected to the lower housing and is located in the inner cavity of the lower housing, and the air duct is formed inside the support body; the support extension is disposed on the top of the support body, and is exposed when the upper housing is separated from the lower housing, and the first operating switch and the second operating switch are disposed on the support extension.

[0007] In some embodiments of this application, an air bladder opening is provided at the top of the main body of the support, the air bladder opening is connected to the air duct, and the air bladder is connected to the air bladder opening.

[0008] In some embodiments of this application, the first fan and the second fan are disposed at the bottom of the lower housing, and an air inlet is provided at the bottom of the air duct.

[0009] In some embodiments of this application, the first fan and the second fan are arranged at intervals along the width direction of the lower housing; the air duct includes a vertical air duct and a horizontal air duct, the vertical air duct is connected to the horizontal air duct, the vertical air duct is located near the side of the main body of the support, the horizontal air duct is located at the bottom side of the main body of the support, the horizontal air duct extends along the width direction of the lower housing, the first air inlet of the horizontal air duct is near the first fan, and a second air inlet is provided at a lower position of the vertical air duct, the second air inlet being near the second fan.

[0010] In some embodiments of this application, a mounting cavity is formed inside the main body of the bracket, and a battery is disposed inside the mounting cavity.

[0011] In some embodiments of this application, a communication control board is provided on the main body of the bracket.

[0012] In some embodiments of this application, the airbag is provided with a mouthpiece, and an inner cover of the mouthpiece is detachably provided on the outside of the mouthpiece; a mouthpiece plug is provided on the outer cover of the mouthpiece, and the mouthpiece plug is detachably connected to the mouthpiece.

[0013] In some embodiments of this application, the outer cover of the mouthpiece is hemispherical, and when the mouthpiece plug is connected to the mouthpiece, the outer cover of the mouthpiece covers the mouthpiece.

[0014] In some embodiments of this application, the mouth plug and the mouthpiece are magnetically connected.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: The simulated self-rescue device of this application uses a first fan and a second fan instead of an oxygen cylinder as the air source. The cost of the fan is much lower than that of the oxygen cylinder, and the fan can be repeatedly started and used, reducing the overall cost of the equipment. At the same time, it realizes the reuse of the simulated self-rescue device, allowing miners to actually operate the simulated self-rescue device during training, and providing feasible equipment support for practical training.

[0016] This simulated self-rescue device simulates the oxygen supply process of a real self-rescue device through the coordination of an air duct, an airbag, and a fan. When the first operating switch is turned on, the first fan starts, and outside air enters the airbag through the air duct, causing the airbag to slowly inflate. When the second operating switch is turned on, the second fan starts, and both fans work simultaneously, causing the airbag to inflate rapidly. The wearer can directly perceive the change in air volume. This design realistically reproduces the state changes of a real self-rescue device under different operating steps, allowing miners to gain a near-realistic operating experience during training, helping them become familiar with the working process of the self-rescue device and improving their operational proficiency.

[0027] Reference Figure 1 This utility model provides an intelligent training system for operating mine self-rescue devices, comprising portable intelligent training devices 1, 2, and 3, an operator identification and portable intelligent training device matching unit 4, a data aggregation and analysis unit 5, and an information sharing unit 6. Data from the portable intelligent training devices 1-3 is transmitted to the operator identification and portable intelligent training device matching unit 4. The data aggregation and analysis unit 5 analyzes the data and transmits the analysis results to the information sharing unit 6. Of course, in other embodiments, multiple portable intelligent training devices can be configured.

[0028] Reference Figure 2The portable intelligent training device includes an upper housing 7, an inner support 8, and a lower housing 9. The inner support 8 is fixed inside the cavity of the lower housing 9, and the upper housing 7 covers the inner support 8. A latch 19 is installed on the outside of the upper housing 7. A communication control board 11, an air duct 12, a battery 14, a miniature fan 15, a miniature fan 16, an airbag opening 18, and a motion sensing sensor are installed on the inner support 8.

[0029] The rechargeable battery 14, motion sensing sensor, and communication control board 11 enable the acquisition of operational actions and the wireless transmission of data to the operator identity and portable smart training device matching unit 4.

[0030] A unique number 17 is set on the middle of the exterior of the lower shell 9. The number is Arabic numeral and the characters are large, making it easy for the carrier to observe and identify.

[0031] The portable intelligent training device uses two miniature fans for air supply. Miniature fan 15 is associated with opening the oxygen valve 10; miniature fan 2 16 is associated with pressing the supplemental air pressure plate 13. An air duct 12 connects miniature fan 15, miniature fan 2 16, and the air bladder opening 18 at both ends. Opening the oxygen valve 10 activates miniature fan 15; pressing the supplemental air pressure plate 13 activates miniature fan 2 16; releasing the pressure plate deactivates miniature fan 2 16; closing the oxygen valve 10 deactivates both miniature fan 15 and miniature fan 2 16. Both the oxygen valve 10 and the supplemental air pressure plate 13 are motion sensing sensors.

[0032] Reference Figure 3 The operator identification and portable smart training device matching unit 4 can communicate concurrently with multiple (e.g., forty) portable smart training devices and measure the real-time distance between them to perform image identification of operators who enter the matching unit within approximately 1.2 meters. It selects the corresponding number of the portable smart training device to establish a training device affiliation, facilitating data aggregation and analysis. The lower part of the operator identification and portable smart training device matching unit 4 has ten independent spaces 20, which can accommodate the simultaneous charging of 2-10 portable smart training devices.

[0033] Reference Figure 4 One end of the airbag 25 is connected to a mouthpiece 21, and the other end of the mouthpiece 21 is connected to the inner cover 24 of the mouthpiece. A mouthpiece plug 23 is disposed inside the outer cover 22 of the mouthpiece, and the mouthpiece plug 23 is detachably connected to the mouthpiece 21.

[0034] The outer cover 22 of the mouthpiece is made of soft silicone and is hemispherical, containing a mouthpiece plug 23. The mouthpiece 21 and the mouthpiece plug 23 are connected magnetically. The inner cover 24 of the mouthpiece is for single use only, avoiding direct contact between the operator and the mouthpiece 21. It is made of replaceable soft materials such as film or mask cloth to isolate the mouthpiece 21 and the mouthpiece plug 23. The outer cover 22 of the mouthpiece is for multiple uses.

[0035] Reference Figure 5 This utility model also provides an operation method for the intelligent training system for the operation of the mine self-rescue device, including the following steps: S1. Preparation: Turn on the portable smart training device, confirm that the wireless link communication is normal, identify, verify and confirm the operator's identity in the operator identity and portable smart training device matching unit 4, observe the number on the shell of the portable smart training device to confirm that the matching is successful, observe the information sharing unit 6 to confirm that the personal identity and the portable smart training device number correspond one-to-one and that operation is allowed.

[0036] S2. Simulation operation: Open the latch 19, open the top cover, turn on the oxygen valve 10, the miniature fan 15 starts to work, and the air bag 25 slowly inflates; remove the outer cover 22 of the mouthpiece, put the mouthpiece 21 and the inner cover 24 of the mouthpiece into the mouth, clip on the nose clip, press the supplemental air pressure plate 13, the miniature fan 26 starts to work, and the air bag 25 inflates rapidly.

[0037] S3. Data transmission: The portable intelligent training device collects operation actions and transmits the data wirelessly to the operator identity and portable intelligent training device matching unit 4. The wireless method adopts the UWB communication mechanism to achieve a ranging accuracy of about 0.3m. The operator identity and portable intelligent training device matching unit 4 communicates concurrently with forty portable intelligent training devices and measures the real-time distance between them.

[0038] S4. Data Analysis: The data aggregation and analysis unit 5 aggregates the data of multiple operators and the portable intelligent training device matching unit 4, analyzes the detailed operation time of each action, the completeness of the actions, whether the total time is within 30 seconds, and whether all personnel meet the standard, and sends the analysis results to the information sharing unit 6.

[0039] S5. Result Display: Information sharing unit 6 collects video of the entire operation process, identifies and reconfirms the operator's identity, displays the operation results, and dynamically updates the current operator's results in real time for the operator to view.

[0040] Data from multiple multi-user matching units (4) is aggregated and shared. Within a shared camera range and on a unified large screen, each operator can observe and confirm their identity, the binding status with the training device, and the operation results. In the one-person-one-screen-one-camera mode, each operator stands in a designated position and operates using a dedicated camera and screen. All operators operate in parallel, and the entire process is captured by the camera.

[0041] In some embodiments of this application, the portable intelligent training device described above is the simulated self-rescue device 33. Figure 6 This is a structural diagram simulating the self-rescue device 33. Figure 7 This is a structural diagram simulating the self-rescue device 33 after opening its upper casing 7. Figure 8 This is a cross-sectional view simulating the self-rescue device 33 after the upper housing 7 is opened. Figure 9 This is a structural diagram of an internal support 8.

[0042] The simulated self-rescue device 33 includes a housing 32, which comprises an upper housing 7 and a lower housing 9, detachably connected. The upper housing 7 and lower housing 9 are vertically joined. A latch 19 is directly installed between the upper housing 7 and lower housing 9, configured to lock them together. To operate the simulated self-rescue device 33, first open the latch 19 and remove the upper housing 7.

[0043] The simulated self-rescue device 33 includes an internal support 8. Figure 9 This is a structural diagram of the inner support 8. The inner support 8 is fixedly mounted on the lower housing 9 and is located within the inner cavity of the housing 32. The inner support 8 serves as a mounting carrier for other components of the housing 32.

[0044] The simulated self-rescue device 33 includes an air duct 12, which is formed on the inner support 8. The air duct 12 serves as a gas delivery channel.

[0045] The simulated self-rescue device 33 includes an airbag 25, which is connected to the inner support 8 and communicates with the air duct 12. Outside air enters the airbag 25 through the air duct 12. Figures 7 to 9 The airbag 25 was omitted from the text.

[0046] The simulated self-rescue device 33 includes a first operating switch and a second operating switch, both of which are mounted on the inner support 8. The first operating switch is the oxygen valve 10 mentioned earlier, and the second operating switch is the air supply pressure plate 13 mentioned earlier. Motion sensing sensors are installed on both the first and second operating switches. For example, the motion sensing sensors are omnipolar Hall effect sensors.

[0047] The simulated self-rescue device 33 includes a first fan configured to activate when the first operating switch is turned on to guide outside air into the air duct 12. The first fan is the aforementioned miniature fan 15. When the operator triggers the first operating switch, the first fan turns on, that is, the miniature fan 15 turns on, and outside air enters the air duct 12 and then into the airbag 25.

[0048] The simulated self-rescue device 33 includes a second fan configured to activate when the second operating switch is turned on, thereby drawing outside air into the air duct 12. This second fan is the aforementioned miniature fan 16. When the operator triggers the second operating switch, the second fan activates, i.e., the miniature fan 16 activates, allowing outside air to enter the air duct 12 and then into the airbag 25.

[0049] The first operating switch is designed in the shape of an oxygen valve, and the second operating switch is designed in the shape of a gas replenishment pressure plate. These designs visually correspond to the key operating components of a real self-rescue device. This design facilitates operators' understanding of the connection between simulated operation and real self-rescue device operation during training. When encountering danger underground and wearing the actual self-rescue device, operators can quickly and accurately identify and operate the corresponding components, reducing delays in escape time due to unfamiliarity with the operation, improving the accuracy of operation in dangerous situations, and thus ensuring the safety of miners' lives.

[0050] When using the simulated self-rescue device 33, first open the latch 19; then remove the upper shell 7; turn on the first operating switch, the first fan turns on, and outside air enters the airbag 25 through the air duct 12, and the airbag 25 slowly inflates; remove the plug of the airbag 25 and put the mouthpiece 21 of the airbag 25 into your mouth; turn on the second operating switch, the second fan turns on, and outside air enters the airbag 25 through the air duct 12. At this time, both fans are working, the airbag 25 inflates rapidly, and the wearer can directly feel the change in air volume.

[0051] Existing self-rescue devices are expensive and non-reusable due to the inclusion of oxygen cylinders, making it difficult for miners to practice using them in safety training. The simulated self-rescue device 33 of this application uses a first and second fan instead of an oxygen cylinder as the air source. The cost of the fans is far lower than that of the oxygen cylinders, and the fans can be repeatedly started and used, reducing the overall cost of the equipment. At the same time, it enables the simulated self-rescue device 33 to be reused, allowing miners to practically operate the simulated self-rescue device 33 during training, providing feasible equipment support for hands-on training.

[0052] The simulated self-rescue device 33 of this application simulates the oxygen supply process of a real self-rescue device through the cooperation of the air duct 12, the airbag 25, and the fan. When the first operating switch is turned on, the first fan starts, and outside air enters the airbag 25 through the air duct 12, causing the airbag 25 to slowly inflate. When the second operating switch is turned on, the second fan starts, and the two fans work simultaneously, causing the airbag 25 to inflate rapidly, allowing the wearer to directly perceive the change in air volume. This design realistically reproduces the state changes of a real self-rescue device under different operating steps, allowing miners to gain a near-realistic operating experience during training, helping them become familiar with the working process of the self-rescue device and improve their operational proficiency.

[0053] In some embodiments of this application, the inner support 8 includes a support body 801 and a support extension 802. The support body 801 is fixedly connected to the lower housing 9, and the support body 801 is located in the inner cavity of the lower housing 9. The air duct 12 is formed inside the support body 801. The support extension 802 is disposed on the top of the support body 801. When the upper housing 7 is separated from the lower housing 9, the support extension 802 is exposed. The first operating switch and the second operating switch are disposed on the support extension 802.

[0054] When the miner unlocks latch 19 and removes the upper housing 7, the support extension 802 separates from the upper housing 7 and becomes exposed. At this point, the first and second operating switches located on the support extension 802 are directly exposed within the operator's field of vision. This structural design closely matches the operating scenario of a real self-rescue device. In a real self-rescue device, the core operating components are also exposed after the outer shell is opened. Therefore, this design can guide miners to develop a conditioned reflex during training to see the operating components immediately upon opening the cover, shortening the reaction time from opening the housing to performing the operation and strengthening muscle memory for emergency operations.

[0055] The main body 801 of the support frame is fixedly connected to the lower shell 9, and an air duct 12 is formed inside it. This makes the air duct 12 an integrated part of the inner support frame 8, avoiding airflow leakage or loose installation problems that might occur if the air duct 12 and the support frame were separate. After the fan is started, outside air is stably transmitted to the airbag 25 through the air duct 12 inside the main body, ensuring the continuity and stability of the air volume during the inflation process of the airbag 25. This ensures that the miner can more accurately perceive the difference in air volume between the initial oxygen supply and the enhanced air replenishment stages, thereby improving the realism of the simulation training.

[0056] In some embodiments of this application, the top of the main body 801 of the support is provided with an air bladder opening, referred to as the first air bladder opening 181. The first air bladder opening 181 is connected to the air duct 12, and the air bladder 25 is connected to the first air bladder opening 181.

[0057] The support extension 802 is located on one side of the support body 801, and the first airbag opening 181 is located on the other side of the support body 801. Installation space for the airbag 25 is reserved beside the support extension 802. This left-right separation layout effectively avoids structural interference between the first and second operating switches and the airbag 25 during installation and use. When the airbag 25 is connected to the air duct 12 and deployed, its expansion space is not limited by the support extension 802 and the operating switches. It can naturally inflate and maintain a stable shape, accurately simulating the working state of the airbag 25 in a real self-rescue device, ensuring that the miner's perception of the airbag 25's wearing and operation during training is consistent with the actual scenario.

[0058] The first airbag opening 181 is directly connected to the air duct 12, and the airbag 25 achieves a sealed connection with the air duct 12 through the first airbag opening 181. This structural design reduces bends and gaps in the airflow transmission path. When the first fan or the second fan is activated, outside air can directly and efficiently enter the airbag 25 through the air duct 12, avoiding air volume loss or airflow turbulence caused by unreasonable connection structure. At the same time, the stable connection between the airbag 25 and the first airbag opening 181 ensures that the airbag 25 will not fall off due to airflow impact during inflation, further ensuring the realism of air volume change perception in simulated training.

[0059] In some embodiments of this application, the first fan and the second fan are disposed at the bottom of the lower housing 9, and the bottom of the air duct 12 is provided with an air inlet.

[0060] Specifically, the first fan and the second fan are arranged at intervals along the width direction of the lower housing 9.

[0061] The air duct 12 includes a vertical air duct 121 and a horizontal air duct 122, with the vertical air duct 121 communicating with the horizontal air duct 122. The vertical air duct 121 is located near the side of the main support body 801. The horizontal air duct 122 is located on the bottom side of the main support body 801. The horizontal air duct 122 extends along the width direction of the lower housing 9. The first air inlet 123 of the horizontal air duct 122 is near the first fan. A second air inlet 124 is located at a lower position of the vertical air duct 121, near the second fan.

[0062] When the first fan starts, the airflow can directly and quickly enter the air duct 12 through the first air inlet 123 of the horizontal air duct 122. When the second fan starts, the airflow can efficiently converge through the second air inlet 124 of the vertical air duct 121, avoiding the airflow dispersion problem caused by the misalignment of the fan and the air inlet. This ensures that the inflation response speed and air volume change of the airbag 25 in both operating states meet the design expectations, and improves the realism of the simulated oxygen supply process.

[0063] The spacing of the fans and the branching design of the air duct 12 (the horizontal air duct 122 and the vertical air duct 121 are connected) ensure independent airflow transmission when a single fan is working, and also achieve effective superposition of airflow when two fans are working. The airflow of the first fan is mainly transmitted through the horizontal air duct 122, while the airflow of the second fan merges into the main air duct 12 through the vertical air duct 121. The two airflows merge within the air duct 12 but do not interfere with each other, making the difference between the slow inflating of the airbag 25 when a single fan starts and the rapid inflating of the airbag 25 when two fans start more significant.

[0064] The first and second fans are located at the bottom of the lower housing 9, making full use of the unused space at the bottom of the lower housing 9 and avoiding structural conflicts with the upper components such as the inner support 8 and the airbag 25.

[0065] In some embodiments of this application, a mounting cavity is formed inside the main body 801 of the bracket, and a battery 14 is disposed within the mounting cavity. The battery 14 is a rechargeable battery, which supplies power to electrical components such as operating switches and fans. A charging port (not shown) is provided on the lower housing 9, through which the battery 14 is charged. The main body 801 of the bracket integrates the air duct 12 and the battery 14, resulting in a compact structure.

[0066] In some embodiments of this application, a communication control board 11 is provided on the main body 801 of the bracket. The communication control board 11 is connected to a first operating switch, a second operating switch, a first fan, and a second fan. The main body 801 of the bracket also serves as a mounting carrier for the communication control board 11, resulting in a compact structure.

[0067] When the operator triggers the first operation switch, the switch signal can be transmitted to the communication control board 11 in real time, and the control board then drives the first fan to start; when the second operation switch is triggered, the signal is also processed by the control board and drives the second fan to start.

[0068] In some embodiments of this application, reference is made to Figure 4 An air bladder 25 has an air bladder opening, designated as the second air bladder opening 182, on its bottom side. The second air bladder opening 182 connects to the first air bladder opening 181 of the air duct 12, thus connecting the air bladder 25 to the air duct 12. A mouthpiece 21 is located on the top side of the air bladder 25, and a removable inner cover 24 is provided on the outer side of the mouthpiece 21. The inner cover 24 is made of a disposable, replaceable flexible material and covers the mouthpiece 21. When the mouthpiece 21 is placed in the mouth, the inner cover 24 prevents the operator from directly contacting the mouthpiece 21, ensuring cleanliness and hygiene. Furthermore, in multi-person training scenarios, each operator can replace the inner cover 24 before use, avoiding direct contact with the surface of the mouthpiece 21 and effectively preventing cross-contamination.

[0069] A mouthpiece plug 23 is provided on the outer cover 22 of the mouthpiece, and the mouthpiece plug 23 is detachably connected to the mouthpiece 21. The outer cover 22 and the mouthpiece plug 23 form a plugging assembly. When the mouthpiece 21 is not in use, the mouthpiece plug 23 is connected to the mouthpiece 21, and the outer cover 22 serves to shield the mouthpiece 21 from dust. When it is necessary to put the mouthpiece plug 23 into the mouth, the mouthpiece plug 23 is removed.

[0070] In some embodiments of this application, reference is made to Figure 4 The outer cover 22 of the mouthpiece is hemispherical. When the mouthpiece plug 23 is connected to the mouthpiece 21, the outer cover 22 of the mouthpiece covers the mouthpiece 21, thereby achieving the function of shielding and preventing dust from the mouthpiece 21.

[0071] In some embodiments of this application, the mouth plug 23 and the mouthpiece 21 are magnetically connected.

[0072] In some embodiments of this application, a training system for simulating the operation of a mine self-rescue device is provided, including a training all-in-one machine 26 and a simulated self-rescue device 33. Figure 3 This is a structural diagram of the training all-in-one machine 26, and the simulated self-rescue device is the simulated self-rescue device 33 mentioned above.

[0073] The training all-in-one machine 26 is equipped with a screen 31, a camera 30, and multiple independent compartments 20. The independent compartments 20 serve as charging and storage compartments for the simulated self-rescue device 33. When the simulated self-rescue device 33 needs charging, it is placed inside the independent compartment 20, and the charging plug on the independent compartment 20 connects to the charging port on the simulated self-rescue device 33 to charge the battery 14. When not in use, the simulated self-rescue device 33 can also be placed inside the independent compartment 20 as storage space.

[0074] The training all-in-one machine 26 communicates wirelessly with the simulated self-rescue device 33. The camera 30 simultaneously captures the operation process of multiple simulated self-rescue devices 33 within a set range (e.g., 1.2m) of the training all-in-one machine 26 and displays it on the screen 31.

[0075] The training system described in this application utilizes multiple independent spaces 20 within the training all-in-one machine 26 to simultaneously store and retrieve multiple simulated self-rescue devices 33. It also employs cameras 30 to synchronously capture the operation processes of multiple simulated self-rescue devices 33 within a set range, displaying multiple operation screens in real-time on a screen 31. This training system supports multiple miners conducting parallel practical training within the same timeframe, significantly shortening the total training time for batches and effectively improving training efficiency. It is particularly suitable for large-scale centralized training scenarios for miners in mines.

[0076] The independent space 20 of the training all-in-one machine 26 has both charging and storage functions. When the simulated self-rescue device 33 is not in use, it can be stored inside to avoid loss or damage caused by random placement of the equipment. When needed, the charging plug of the independent space 20 is connected to the charging port of the simulated self-rescue device 33 to complete the charging and ensure that the equipment is always fully charged and usable.

[0077] Camera 30 can simultaneously capture the operation process of multiple simulated self-rescue devices 33 within a set range, and display multiple operation screens synchronously on screen 31. The display function of screen 31 enables visual review of the operation process, helping miners intuitively understand their own operational shortcomings and enhance training effectiveness.

[0078] The simulated self-rescue device 33 is reusable, avoiding the high training costs associated with the single-use of real self-rescue devices. Simultaneously, the wireless communication design between the training all-in-one machine 26 and the simulated self-rescue device 33 reduces cable connection limitations, allowing for more flexible training scenario setups and adaptability to different site conditions. Combined with real-time data acquisition from the camera 30 and feedback from the screen 31, miners complete training in a near-realistic operating environment, reducing unit training costs while ensuring a realistic operational experience, thus helping to improve miners' operational proficiency in actual emergency scenarios.

[0079] In some embodiments of this application, the training all-in-one machine 26 includes a lower body 28 and an upper body 27. The upper body 27 is provided with the screen 31 and the camera 30. The lower body 28 is provided with the independent space 20. An identity recognition area 29 is provided between the upper body 27 and the lower body 28.

[0080] Before using the simulated self-rescue device 33, miners can complete identity verification in the identification area 29 (such as swiping their ID card or miner's badge). The system automatically links the operator's information with subsequent operation data. When returning the device after operation, the identification area 29 can reconfirm the identity, forming a closed-loop record. This design ensures that each practical training session is accurately assigned to an individual, providing a data foundation for establishing training records.

[0081] In some embodiments of this application, reference is made to Figures 6 to 9 The simulated self-rescue device 33 includes a housing 32, an inner support 8 within the inner cavity of the housing 32, an air duct 12 formed inside the inner support 8, an airbag 25 mounted on the inner support 8 and communicating with the air duct 12, and an operating switch mounted on the inner support 8. The simulated self-rescue device 33 also includes a fan configured to activate when the operating switch is turned on to guide outside air into the air duct 12. Motion sensing sensors are mounted on the housing 32, the airbag 25, and the operating switch.

[0082] Motion sensors on each component enable precise capture of operational details. Sensors on the housing 32 detect the separation state of the upper housing 7 and lower housing 9, such as the opening of the latch 19 and the removal of the upper housing 7, ensuring that the initial step of opening the cover is accurately recorded. Sensors on the airbag 25 detect whether the airbag 25 is placed in the mouth. Sensors on the operating switch accurately identify the switch's trigger state. The coordinated operation of multiple sensors forms a complete data chain of actions from opening the cover to completion of wearing the device, avoiding missing steps due to a single sensor's failure to detect.

[0083] The motion data collected by the motion sensing sensor can be linked with the control and analysis module of the training all-in-one machine 26 to generate a multi-dimensional operation evaluation report. After this data is associated with the personal information bound to the identity recognition area 29, it can provide miners with personalized operational shortcomings analysis and instructors with statistics on the overall weaknesses of the team, making training guidance more targeted.

[0084] In some embodiments of this application, a communication control board 11 is provided on the inner support 8, the training all-in-one machine 26 includes a control analysis module, the motion sensing sensor is connected to the communication control board 11, and the communication control board 11 is connected to the control analysis module.

[0085] The motion sensing sensors transmit the motion signals collected by components such as the housing 32, airbag 25, and operating switches to the communication control board 11 in real time. The communication control board 11 then sends the data wirelessly to the control and analysis module of the training all-in-one machine 26. Even when multiple simulated self-rescue devices 33 are operating simultaneously, the control and analysis module can still quickly receive and process the data, providing support for real-time monitoring and feedback. After receiving the sensor data, the control and analysis module uses algorithms to analyze and determine whether the operation is standardized.

[0086] The structural configurations of the housing 32, inner bracket 8, air duct 12, operating switch, and fan have been described previously and will not be repeated here. The specific configuration of the motion sensing sensor is as follows: A first motion sensing sensor is provided on the upper housing 7. The first motion sensing sensor determines whether the step of "removing the upper housing 7" has been completed by detecting the separation state between the upper housing 7 and the lower housing 9.

[0087] The housing 32 is provided with a latch 19, and a second motion sensing sensor is provided on the latch 19. The second motion sensing sensor is specifically used to identify the locked / unlocked state of the latch 19 and determine whether the "unlocking latch 19" step has been completed.

[0088] The airbag 25 is equipped with a mouthpiece 21, and the mouthpiece 21 is equipped with a third motion sensing sensor. The third motion sensing sensor detects whether the mouthpiece 21 is placed in the operator's mouth.

[0089] The first operating switch is equipped with a fourth motion sensing sensor, and the second operating switch is equipped with a fifth motion sensing sensor. The fourth and fifth motion sensing sensors respectively capture the trigger signals of the two switches, distinguishing between the initial oxygen supply and the enhanced oxygen replenishment operation commands. Combined with fan speed data, this verifies the operator's understanding of the oxygen supply intensity adjustment logic and prevents operational errors caused by confusing the switch functions.

[0090] The control and analysis module can calculate the time taken from unlocking to opening the lid by combining data from the first and second motion sensing sensors, thus assessing the operator's emergency response speed. By comparing the trigger intervals of the fourth and fifth motion sensing sensors, it can determine the operator's ability to grasp the timing of gas replenishment. After these detailed data are linked with identification information, a personal training profile can be generated, including the compliance rate of procedures, the distribution of time taken, and weaknesses. This provides data support for targeted training and solves the subjective problem of experience-based assessment in traditional training.

[0091] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0092] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
