Description

Technical Field

[0001] The present invention belongs to the technical field of equipment control systems in the construction industry, and in particular relates to an intelligent control system for a pneumatic escape device and a control method thereof. Background Art

[0002] With the acceleration of urbanization, high-rise buildings are increasing, and the safety issues in their construction phase are becoming increasingly prominent. However, most of the existing relevant escape devices are used in already built buildings. Among them, some complex escape devices, such as slide escape devices, fixed escape ladders and suspended escape ladders, often need to be fixedly connected to the already built buildings, and are suspended or set on the outer wall of the building to provide sufficient support for the escapees to climb or control the escape descent speed by themselves, occupying a large structural space and expensive. At the same time, this type of escape device requires the escapees to control themselves, so it has high requirements for the psychological quality and control experience of the escapees themselves. For example, the slide escape device requires the escapees to enter the long bag-like object inside it from a high place and slowly slide down, and rely on their own weight and different postures to control the descent speed. Some simple escape devices such as escape slow descenders and emergency escape devices are often composed of hooks, slings, ropes, speed controllers, and sliding control mechanisms. They need to rely on the escapees' own weight to slowly settle, and have extremely high requirements for the escapees from wearing to controlling the speed. In an emergency, improper operation may lead to serious safety accidents.

[0003] In other words, most of the existing escape devices are slow-descent designs, which have disadvantages such as insufficient stability and slow escape speed, and most of these devices cannot be used in the construction stage for various reasons. Specifically, the existing escape devices have the following deficiencies, which limit their application in the construction stage:

[0004] 1. Existing escape devices are often designed for existing buildings and rely on the structure of the existing buildings themselves. They need to be supported by fixed installation points or specific building structures, which may not be established during the construction stage. If the fire has spread to the entire building, even if this type of slow-down device is used, there will still be a risk of falling and burns. Moreover, these escape devices basically need to be attached to high-rise buildings to work and lack independence. If the fire causes the building to collapse or the building's annexes to fall, this type of escape device will not be able to play a rescue role.

[0005] 2. In addition, the existing escape devices are complex to operate and require professional training, while construction workers may lack the corresponding training and experience, resulting in the inability to effectively use these devices in emergency situations. The dynamic environment of the construction phase further increases the complexity and risk of using these escape devices. At the same time, in the temporary structures or incomplete building environments during the construction phase, the psychological and behavioral characteristics of construction workers may lead to the inability to effectively use fire rescue escape devices, which lack stability and controllability.

[0006] 3. The single rescue carrying capacity of the existing escape device is also limited. It is mainly designed for individuals and cannot rescue multiple escapees at the same time. The escape efficiency is low. In addition, due to the use of rope structures such as safety belts, safety hooks, and wire ropes, there is a problem of mutual entanglement when multiple people use it at the same time. Especially when the construction reaches high-rise, these problems are more prominent. Environmental factors such as on-site temperature and ventilation conditions will affect the performance of the escape device.

[0007] Therefore, in order to solve the problem of high-rise workers having difficulty escaping when a dangerous situation occurs during the construction phase, it is urgent to develop and design an intelligent control system and a control method for a pneumatic escape device specifically suitable for the construction phase. In this design, a human ladder-shaped hanging basket platform is considered, combined with a pneumatic jacking device independent of the building, and controlled in conjunction with an intelligent control system to ensure the overall stability, safety and escape efficiency of the escape device during the jacking and descending processes.

[0008] The lifting and lowering of existing pneumatic lifting devices are often limited by their design and performance, resulting in unstable lifting and difficult speed control. Too slow a rise or descent speed may delay rescue time; and blindly pursuing a fast but unstable rise process may cause abnormal stress on certain component structures of the escape device, resulting in equipment damage and affecting its normal function, which is fatal in emergency fire disasters; in addition, when the descent speed is too fast, it will not only exceed the safety threshold of the escape device design, causing damage or failure of the device, but may also cause the escapee to be severely impacted when reaching the ground, causing fractures, internal organ damage and other serious injuries, and may even lead to death. Therefore, it is particularly critical to ensure that the escape device always maintains an appropriate and stable lifting speed and ensures the operating safety of the escape device itself through a reliable intelligent control system. Summary of the invention

[0009] In order to solve the problems existing in the prior art mentioned above, the purpose of the present invention is to provide an intelligent control system and a control method for a pneumatic escape device, which greatly improves the rescue efficiency, safety and applicability by realizing intelligent control in multiple links such as jacking, descending, monitoring and diagnosis, and has the effect of energy saving and environmental protection; and, through sensors and intelligent algorithms, it also ensures the smooth and efficient operation of the device under various working conditions, and through real-time data processing and analysis, provides intelligent decision-making support for the escape process, effectively solving the problem of high-level workers quickly escaping from the scene when a dangerous situation occurs during the construction stage and the construction elevator cannot be used.

The fixing socket has a shape matching the shape of the fixing pile head 141, so as to facilitate the assembly and fixation between the two structural outer frames 11 of the upper and lower adjacent layers.

[0067] The telescopic limit assembly 12 is horizontally distributed on the inner side of the structural outer frame 11 along the height direction of the structural outer frame 11; the telescopic limit assembly 12 includes a plurality of limit telescopic rods 121, and each of the limit telescopic rods 121 in any of the telescopic limit assemblies 12 is located on the same horizontal plane, and the rear ends of the limit telescopic rods 121 are fixed on the inner side wall of the structural outer frame 11, and the front ends of the limit telescopic rods 121 are each provided with a sliding roller 122; preferably, the distance from the limit telescopic rod 121 to the inner side wall of the nearest structural outer frame 11 is greater than the distance from the outer side wall of the air cylinder at the current height of the air pressure lifting device 4 to the inner side wall of the nearest structural outer frame 11, thereby ensuring that after the limit telescopic rod 121 performs telescopic movement, the rolling pulley can always contact the outer side wall of the air cylinder at the same height.

[0074] The pressure sensor is arranged inside the first-stage air cylinder 43 to monitor the air pressure inside the multi-stage air cylinder, thereby ensuring the normal operation of the air pressure lifting device and avoiding the direct influence of the lifting capacity of the air pressure lifting device 4 due to the change of air pressure.

[0081] The gas detector is arranged on the top of the hanging basket 22 for real-time monitoring of the concentration of specific gases in the environment, specifically, monitoring the smoke concentration in the air and possible harmful gases in the smoke, such as carbon monoxide, to ensure the safe evacuation of personnel and assist in disaster management.

[0082] The data collection and analysis unit includes a local data processing module and a cloud analysis and processing platform.

[0083] The local data processing module is connected to the monitoring unit and the control and adjustment unit 8 by signal, and is used to collect real-time data transmitted from each sensor of the monitoring unit, and perform local instant data processing and calculation analysis; the real-time data includes air pressure, speed, load, height, fire source, temperature, smoke concentration, and concentration of harmful gases in the smoke, and then the data obtained by calculation and analysis are transmitted to the corresponding module in the adjustment and control unit, and the air pressure pump 41 and the air relief valve 42 in the air pressure lifting device 4, the telescopic limit assembly 12 in the structural outer frame 11 unit 1, the fine-tuning suspension mechanism 23 in the suspension rescue basket unit 2, and the spray device 5 are respectively regulated by the adjustment and control unit to realize the height adjustment and lifting mode switching of the air pressure escape device, and realize the spray mode switching at the same time; in addition, the data transmitted by each sensor of the monitoring unit collected by the local data processing module and the data obtained by calculation and analysis are transmitted to the visualization module, and are synchronously uploaded to the cloud analysis and processing platform. Specifically, the local data processing module adopts an edge computing architecture to place data processing and computing tasks close to the data source, that is, to perform them at the "edge", that is, to place data processing and computing tasks close to the data source and perform them at the "edge", rather than in a centralized data center. By decentralizing rather than centralizing edge computing in the local data processing module, the path length of data transmission to the cloud analysis and processing platform or central server can be effectively reduced, the response speed can be improved, the delay can be reduced, and the burden on the data center can be reduced. At present, edge computing is generally used in scenarios with extremely high requirements for data processing speed, such as Internet of Things (IoT) devices, self-driving cars, and real-time video analysis, but it is rarely used in escape devices.

[0084] In actual work, the local data processing module performs calculation and analysis based on the data processing calculation model of air pressure change, lifting rate, load weight and feedback from the cloud analysis and processing platform, and obtains the target working power that the air pressure pump 41 currently needs to adjust or the target opening degree that the air relief valve 42 currently needs to adjust. At the same time, the local data processing module performs intelligent analysis of the fire hazard level through intelligent hazard judgment technology based on the environmental data of the flame sensor, temperature sensor and gas detector, that is, based on the environmental data of the fire source, temperature, smoke concentration and the concentration of harmful gases in the smoke, and accurately captures the location of the fire source and high temperature area through laser positioning and thermal imaging technology, so as to achieve accurate directional spraying, significantly reduce the waste of water resources, and ensure the maximum efficiency of fire extinguishing and protection. At the same time, the environmental data is analyzed in real time through edge computing, and the analysis results are transmitted to the spray control module, and the spray control module controls the spray device 5 to switch the corresponding spray mode, and controls the spray device 5 to spray water mist downward, and dynamically adjusts the spray intensity and coverage to adapt to the continuous changes in the dangerous environment.

[0085] The cloud-based analysis and processing platform is used to collect data from the local data processing module and process and analyze it through high computing power. The processing and analysis through high computing power includes but is not limited to the training and optimization of deep learning models, analysis of long-term trends, and mining of historical data, so as to continuously optimize the algorithm model. At the same time, it also supports deep learning of large-scale data sets, improves the intelligence level of the control system of the pneumatic escape device, and feeds back the optimized data processing calculation model to the local data processing module, so as to continuously optimize the calculation and analysis capabilities of the local data processing module. For example, a cloud-based analysis and processing platform can be used to provide a multi-stage pressure relief mode for the control system, and the deflation rate at each stage can be accurately controlled based on the real-time height position of the escaped personnel and the on-site building height monitored by the height sensor; when the height position is on the high floors of the building, the control system switches to the high-speed escape mode, and accelerates the escape process through rapid pressure relief; when the height position is on the middle floors of the building, the control system switches to the uniform-speed pressure relief mode, and improves stability through uniform speed control in the middle; when the height position is on the low floors of the building, the control system switches to the low-speed descent mode, and ensures a soft landing through terminal deceleration control, which not only improves the overall descent efficiency, but also significantly enhances safety; specifically, in the low-speed descent mode, the system automatically achieves a soft landing by gradually reducing the deflation rate at the end of the descent, thereby significantly reducing the impact force and improving the safety and comfort of landing.

[0086] The visualization module includes a display screen, which receives data from the local data processing module and displays it on the display screen in real time. Through the visualization interface of the display screen, the environmental data of the pneumatic escape device, the working status of the pneumatic escape device, and the height of the current position of the escapee can be displayed in real time; the environmental data include temperature, smoke concentration and the concentration of harmful gases in the smoke, which can confirm the degree of danger of the environment in which the personnel are located in real time; the working status of the escape device includes the current mode of the pneumatic jacking device 4, the working power of the pneumatic pump 41, the air pressure in the first-level pneumatic cylinder 43, the opening degree of the air relief valve 42, and the current mode of the spray device 5, so as to ensure the stable operation of the escape device. At the same time, it can also track and display the height of the current position of the escapee in real time to confirm the progress of the escape; further, in other embodiments, the display screen adopts graphical display, so that the changes in each data are displayed more intuitively and clearly.

[0087] The control and adjustment unit 8 is used to control the switching and adjustment of the air pressure pump 41, the air intake valve 47, the air release valve 42, the air outlet valve, the positioning fixing pin 46, the telescopic limit assembly 12, the fine-tuning suspension mechanism 23 and the spray device 5 in the pneumatic escape device, and includes an air intake control module, an air release control module, a guide adjustment module, a hanging basket fine-tuning module and a spray control module.

[0088] The air intake control module is connected with the air pressure pump 41, the air intake valve 47 and the positioning fixing pin 46 by signal, and is used to synchronously control the start and stop of the air pressure pump 41 of the air pressure lifting device 4 located on the left and right sides and to inject gas into each level of air pressure cylinder in turn to provide lifting power. At the same time, it is used to synchronously adjust the working power of the air pressure pump 41 of the air pressure lifting device 4 located on the left and right sides according to the data calculated and analyzed by the local data processing module to control the speed of the air pressure lifting device 4 during the lifting process. It is also used for the switch control of the corresponding air intake valve 47 and the extension control of the positioning fixing pin 46 when each level of air pressure cylinder is lifted into place, so as to ensure the step-by-step lifting of the air pressure lifting device 4.

It is also used to control the switch of the corresponding air outlet valve and the contraction of the positioning fixing pin 46 when the air pressure cylinders of each level are lowered into place, so as to ensure the step-by-step descent of the air pressure lifting device 4.

[0090] The guide adjustment module is connected to the telescopic limit component 12 by signal, and is used to control the telescopic limit component 12 to perform horizontal telescopic movement to adjust the telescopic length of the telescopic limit component 12, so that the front end of each telescopic limit component 12 contacts the outer side wall of the pneumatic jacking device 4 at the same height, so as to provide auxiliary guide support for the pneumatic jacking device 4, which is used to limit the pneumatic cylinders of each stage in the pneumatic jacking device 4 and assist the vertical lifting of the pneumatic cylinders of each stage.

[0091] The hanging basket fine-tuning module is connected to the signal of the fine-tuning suspension mechanism 23, and is used to control the fine-tuning motor 231 in the fine-tuning suspension mechanism 23 to rotate forward or reverse, and drive the hanging basket 22 for people to move up and down to adjust the height of the hanging basket 22 for people to move.

[0092] Specifically, the fine-tuning suspension mechanism 23 includes a fine-tuning motor 231, a fine-tuning pulley 232 and a fine-tuning suspension rope 233. The lower end of the fine-tuning motor 231 is fixedly connected to the top of the upper hanging basket 22, and the upper end of the fine-tuning motor 231 is provided with the fine-tuning pulley 232. The lower end of the fine-tuning suspension rope 233 passes through the fine-tuning pulley 232 and is wound and fixed on the fine-tuning motor 231. The upper end of the fine-tuning suspension rope 233 is fixed on the top suspension beam 21. The motor 231 is connected to the signal of the hanging basket fine-tuning module, and the hanging basket fine-tuning module controls the fine-tuning motor 231 to perform forward or reverse movement, so that the fine-tuning suspension rope 233 is tightened or loosened with the forward and reverse rotation of the fine-tuning motor 231, thereby driving the upper hanging basket 22 to move up and down, realizing fine-tuning control of the height of the upper hanging basket 22, ensuring that the height of the telescopic pedal 221 on the upper hanging basket 22 is consistent with the height of the exit of the floor to be escaped, thereby ensuring the smooth escape of the escapee.

[0093] The spray control module is connected to the spray device 5 by signal, and is used to control the start and stop of the spray device 5, and control the spray device 5 to switch between three different spray modes: fire extinguishing mode, cooling mode, and smoke isolation mode.

[0094] In a preferred embodiment, a telescopic pedal 221 is further provided at the bottom of the upper hanging basket 22, and the telescopic pedal 221 is used to provide a foothold for escapees, so that it is more convenient for escapees to enter the upper hanging basket 22 from each floor when the pneumatic escape device is in use; at the same time, the control and adjustment unit 8 also includes a pedal telescopic adjustment module, and the pedal telescopic adjustment module is connected to the telescopic pedal 221 by signal, and is used to control the telescopic length of the telescopic pedal 221 to adjust the length of the telescopic pedal 221 extending from the edge of the upper hanging basket 22, so that the length of the telescopic pedal 221 extending from the edge of the upper hanging basket 22 is greater than the distance from the side of the upper hanging basket 22 against the wall 6 to the wall 6, thereby ensuring that the telescopic pedal 221 can be overlapped at the exit of the floor to be escaped. Specifically, a displacement sensor is provided at the front end of the lower end surface of the telescopic pedal 221, and the displacement sensor is used to monitor the telescopic length of the telescopic pedal 221 in real time, and the displacement sensor is connected to the pedal telescopic adjustment module by signal.

[0095] The system also includes an automatic alarm module, which is signal-connected to the local data processing module. When a fire occurs, the local data processing module receives real-time data from the monitoring unit and intelligently identifies and determines the fire hazard, and then generates a real-time report through the automatic alarm module and sends it to relevant government departments or fire alarm platforms.

[0096] The system also includes a communication module, which uses the TCP communication protocol to achieve data transmission between the above modules, and to achieve data transmission between the local data processing module and the cloud analysis and processing platform and the fire alarm platform.

[0097] Example 2

[0098] This embodiment provides a control method for a pneumatic escape device intelligent control system applied to Embodiment 1, comprising the following steps:

[0099] S1. After the pneumatic escape device is installed for the first time, the pneumatic lifting device 4 is fully lifted, and the telescopic limit assembly 12 is controlled by the guide adjustment module to perform horizontal telescopic movement, so that the front end of each telescopic limit assembly 12 contacts the outer side wall of the pneumatic lifting device 4 at the same height.

[0100] S2. When a fire occurs, the lifting height of the air pressure lifting device 4 and the height of the upper hanging basket 22 are determined according to the floor where the fire occurs and the single-story height of the building input in advance, ensuring that the upper hanging basket 22 is not lower than the floor where the fire occurs.

[0101] S3, lift the air pressure lifting device 4 through the air intake control module until the air pressure lifting device 4 is not lower than the lifting height determined in step S2; monitor the gas pressure and lifting speed in real time, calculate and adjust the working power of the air pressure pump 41 for smooth lifting.

[0102] According to the determined lifting height, the air intake control module starts the air pressure pump 41 and opens the air intake valves 47 of each level of air pressure cylinder and extends the positioning fixing pin 46 from the outside to the inside, so that the air pressure lifting device 4 is lifted until the lifting height of the air pressure lifting device 4 is not lower than the lifting height determined in step S2; during the lifting process, the local data processing module receives data on gas pressure and lifting speed monitored in real time by the pressure sensor and the rate sensor, and determines the target working power of the air pressure pump 41 through calculation and analysis, and then feeds back to the air intake control module to adjust the power of the air pressure pump 41 to ensure that the air pressure lifting device 4 rises smoothly.

[0103] S3-1. According to the determined lifting height, the air intake control module controls the air pressure pump 41 to open, and opens the air intake valves 47 and the positioning fixing pins 46 of the air pressure cylinders of each level in the air pressure lifting device 4 from the outside to the inside, until the air pressure lifting device 4 is not lower than the determined lifting height.

[0104] During operation, when the air pressure lifting device 4 is lifting, the air intake control module controls the air pressure pump 41 to open; then, the air intake control module controls each level of air pressure cylinder to open the corresponding air intake valve 47 in sequence from the outside to the inside, until the current air pressure cylinder is lifted into place, controls the positioning fixing pin 46 to extend and fix the current air pressure cylinder, and then continues to open the air intake valve 47 corresponding to the next level of air pressure cylinder 43, and so on, until the target lifting height is reached. If a small height deviation occurs, the height of the hanging basket 22 is adjusted through the hanging basket fine-tuning module in the subsequent steps.

[0105] Specifically, the air intake control module controls the air pressure pump 41 to open, and controls the air intake valve 47 at the bottom of the first-stage air pressure cylinder 43 to open, while ensuring that the air intake valves 47 at the bottom of the other stages of air pressure cylinders remain closed; at this time, the air pressure in the first-stage air pressure cylinder 43 increases, and the second-stage air pressure cylinder 44 in the first-stage air pressure cylinder 43 is lifted up, until the second-stage air pressure cylinder 44 is fully extended, and the air intake control module controls the positioning and fixing pin 46 at the bottom of the second-stage air pressure cylinder 44 to extend, so that the second-stage air pressure cylinder 44 is fixed; then, the air intake control module controls the positioning and fixing pin 46 at the bottom of the second-stage air pressure cylinder 4 The air intake valve 47 at the bottom of the second-stage air pressure cylinder 4 is opened, and the air intake valves 47 at the bottom of other stages of air pressure cylinders are kept closed, the air pressure of the second-stage air pressure cylinder 44 increases, and the third-stage air pressure cylinder located in the second-stage air pressure cylinder 44 is lifted up, until the third-stage air pressure cylinder is fully extended, the air intake control module controls the positioning and fixing pin 46 at the bottom of the third-stage air pressure cylinder to extend, so that the third-stage air pressure cylinder is fixed; and so on, the air intake control module controls the lifting of other stages of air pressure cylinders until the rescue height is reached, and the air intake control module controls the air pressure pump 41 to be closed. At this time, the height of the top suspension beam 21 is not lower than the rescue height.

[0106] S3-2. At the same time, during the lifting operation of the pneumatic escape device, the gas pressure and lifting rate of the pneumatic lifting device 4 are monitored in real time through the pressure sensor and rate sensor in the lifting monitoring module, and the real-time air pressure data and real-time lifting speed are transmitted to the local data processing module. The local data processing module calculates the air pressure change rate according to the lifting rate and the real-time air pressure, and analyzes to obtain the target working power that the air pressure pump 41 currently needs to adjust. The local data processing module feeds back the target working power data that the air pressure pump 41 currently needs to adjust to the air intake control module, thereby controlling and adjusting the working power of the air pressure pump 41 through the air intake control module to achieve a smooth rise of the pneumatic lifting device 4.

[0107] S4. Adjust the height of the hanging basket 22 through the hanging basket fine-tuning module until the height of the hanging basket 22 is consistent with the height of the hanging basket 22 determined in step S2. At the same time, analyze the data of the environmental monitoring module and determine the spray mode through the local data processing module, and control the spray device 5 to switch the corresponding spray mode through the spray control module.

[0108] S4-1, control and adjust the height of the hanging basket 22 for the person getting on the person through the hanging basket fine-tuning module, until the height of the hanging basket 22 for the person getting on the person monitored in real time by the height sensor in the lifting monitoring module is consistent with the height of the hanging basket 22 for the person getting on the person determined in step S2.

[0109] S4-2. At the same time, the flame sensor, temperature sensor and gas detector in the environmental monitoring module are used to monitor the environmental data in real time, and the fire source location, temperature, smoke concentration and harmful gas concentration monitored in real time are transmitted to the local data processing module. The local data processing module analyzes and determines the spray mode that needs to be adjusted for the spray device 5 at present. The local data processing module feeds back the spray mode that needs to be adjusted for the spray device 5 at present to the spray control module, thereby controlling the switching of the spray mode of the spray device 5 through the spray control module; specifically, the spray modes include fire extinguishing mode, cooling mode and smoke isolation mode.

[0110] When a sudden fire occurs, the flame intensity and spreading direction are identified by the flame sensor, and the fire information processing module switches the sprinkler device 5 to the fire extinguishing mode after analysis and judgment; in the fire extinguishing mode, the sprinkler device 5 quickly extinguishes the fire source through high-pressure water mist spraying; and, when the fire is a local fire, concentrated spraying can be carried out on the fire source and high-temperature area to quickly reduce the flame temperature while avoiding water mist interference with other operations; in the fire extinguishing mode, the water mist particles sprayed by the sprinkler device 5 are tiny and can quickly cover the flame surface, cut off the oxygen supply and reduce the combustion temperature, thereby effectively controlling the spread of the fire and ensuring safety within the range of the hanging basket 22; at the same time, the spraying process can also absorb heat, reduce the ambient temperature of the fire source and the high-temperature area, and reduce the threat of high temperature to personnel and escape devices.

[0111] When the surface temperature of the escape path or equipment exceeds the safety threshold, the fire information processing module switches the spray device 5 to the cooling mode after analysis and judgment; in the cooling mode, the spray device 5 cools the high temperature environment through low-pressure spraying; in the cooling mode, the water flow of the low-pressure spray of the spray device 5 evenly covers the surface of the escape device and the surrounding environment, effectively preventing the escape device from failing due to overheating, and at the same time providing comfortable cooling protection for the escapees to avoid dangers such as heat burns.

[0112] When the smoke concentration exceeds the standard or a harmful gas leak is detected, the smoke isolation mode is switched to first. In the smoke isolation mode, the spray device 5 releases a high-density water mist barrier to quickly dilute the smoke and harmful gases in the air, thereby reducing the risk of the respiratory system of the escapee being exposed to a dangerous environment. At the same time, the water mist can also react with some chemical substances to reduce the toxic concentration, provide cleaner air for escape, ensure that the upper hanging basket 22 is not affected by smoke and dust within a certain range during use, and ensure the safety of the escapee and the escape device, thereby buying more time for escape. In addition, the smoke and reduced visibility generated by the fire will limit the escapee's field of vision, thereby affecting the escapee's choice of escape route and escape speed. The high-density water mist spraying in the smoke isolation mode can ensure that the escapee can quickly locate the position of the upper hanging basket 22, thereby improving the escape efficiency.

[0113] S5. After the escapee enters the interior of the hanging basket 22, the air pressure lifting device 4 is lowered through the air release control module until the height data of the height sensor on the hanging basket 22 drops to 0.

[0114] When the escapee enters the interior of the hanging basket 22, the deflation control module opens the deflation valve 42 and opens the outlet valves of the air pressure cylinders at each level from the outside to the inside and retracts the positioning fixing pin 46, so that the air pressure lifting device 4 descends until the height data of the height sensor on the hanging basket 22 drops to 0; during the descent, the local data processing module receives data on gas pressure, lifting speed and load weight monitored in real time by the pressure sensor, rate sensor and load sensor, calculates and analyzes and determines the target opening degree of the deflation valve 42 that needs to be adjusted, and then feeds back to the deflation control module to adjust the opening degree of the deflation valve 42 to ensure that the descent rate is always kept within a safe range (such as 2-5m / s), so as to ensure that the air pressure lifting device 4 descends smoothly and effectively prevents the risks caused by descent too quickly; specifically.

[0115] S5-1. After the load weight of the load sensor is stable, the deflation control module controls the deflation valve 42 to open, and opens the air outlet valves and positioning fixing pins 46 of the air pressure cylinders at each level in the air pressure lifting device 4 from the outside to the inside, until the height data of the height sensor on the hanging basket 22 drops to 0.

[0116] During operation, when the pneumatic lifting device 4 descends, the air release control module controls the air release valve 42 to open, and the air release control module controls the retraction of the positioning fixing pins 46 corresponding to each level of pneumatic cylinders from the outside to the inside, and controls the opening of the air outlet valves corresponding to each level of pneumatic cylinders in turn, and ensures that the air inlet valves 47 at the bottom of each level of pneumatic cylinders remain closed at this time until the current pneumatic cylinder descends into place, and then continues to open the positioning fixing pins 46 and the air outlet valve corresponding to the next level of pneumatic cylinder 43, and so on, until the man-mounted hanging basket 22 reaches the ground 7, that is, the height data of the height sensor of the man-mounted hanging basket 22 drops to 0.

[0117] Specifically, the deflation control module controls the air inlet valve 47 at the bottom of each level of the air pressure cylinder to remain in a closed state, and controls the air outlet valve at the bottom of the first-level air pressure cylinder 43 to open, and at the same time, the air circuit control module controls the positioning and fixing pin 46 at the bottom of the second-level air pressure cylinder 44 to retract; at this time, the air pressure in the first-level air pressure cylinder 43 decreases, and the second-level air pressure cylinder 44 descends until the second-level air pressure cylinder 44 is completely descended and recovered into the first-level air pressure cylinder 43; then, the deflation control module controls the air outlet valve at the bottom of the second-level air pressure cylinder 44 to open, and at the same time controls the positioning and fixing pin 46 at the bottom of the third-level air pressure cylinder to retract, and the third-level air pressure cylinder descends; and so on, the deflation control module controls the other levels of air pressure cylinders to descend until the levels of the air pressure lifting device 4 are completely retracted. If a small amount of height deviation occurs, resulting in the suspension rescue basket device not touching the ground 7 at this time, the height of the man-mounted hanging basket 22 is adjusted by the hanging basket fine-tuning module until the suspension rescue hanging basket device is completely on the ground 7, so as to ensure the stability of personnel during movement.

[0118] S5-2. At the same time, during the descent of the pneumatic escape device, the pressure sensor, rate sensor and load sensor in the lifting monitoring module monitor the gas pressure, descent rate and actual load weight of the pneumatic lifting device 4, and transmit the real-time air pressure data and real-time descent speed to the local data processing module. The local data processing module calculates the air pressure change rate according to the descent rate and real-time air pressure, and in combination with the actual load weight of the hanging basket 22, and analyzes to obtain the target opening degree of the relief valve 42 that currently needs to be adjusted. The local data processing module feeds back the target opening degree data of the relief valve 42 that currently needs to be adjusted to the relief control module, thereby controlling the opening degree of the relief valve 42 through the relief control module, thereby controlling the pressure in the pneumatic cylinder, controlling the descent rate of the escape device, and ensuring the comfort and safety of the personnel.

[0119] S6, after the escapees leave the upper hanging basket 22, that is, after the load weight of the load sensor in the upper hanging basket 22 becomes 0, repeat steps S2 to S5 until all the escapees have escaped.

[0120] In a preferred embodiment, in step S4-1, after the height of the hanging basket 22 is adjusted to the right position, the extension of the telescopic pedal 221 is controlled by the pedal telescopic adjustment module until the length of the telescopic pedal 221 extending out of the edge of the hanging basket 22 as monitored in real time by the displacement sensor is greater than the distance from the side of the hanging basket 22 close to the wall 6 to the wall 6; and, in step S5-1, after the load weight of the load sensor is stable, the contraction of the telescopic pedal 221 is controlled by the pedal telescopic adjustment module to avoid the risk of interference between the telescopic pedal 221 and the wall 6 during the descent, thereby reducing the shaking of the hanging basket 22.

[0121] The system has three air pressure operation modes, which include normal operation mode, energy-saving mode and overload protection mode. In step S3 and step S5, when the load is light or does not need to be lifted quickly, the system switches to energy-saving mode and controls the working power of the air pump 41 to be reduced through the air intake control module to reduce energy consumption, while reducing the wear of the device components and extending the overall service life of the equipment, which not only reduces the operating cost but also improves the reliability of the equipment in long-term use. In steps S3 to S6, when it is detected that the gas pressure inside the air cylinder is too high, the system will immediately switch to the overload protection mode, and control the air relief valve 42 to open for pressure relief through the air relief control module, quickly reduce the pressure in the cylinder, and prevent the equipment from being damaged due to overload, until it returns to normal and switches back to the normal operation mode. The three air pressure operation mode mechanisms can not only effectively avoid the safety threats to personnel caused by the loss of control of the pneumatic escape device, provide multi-level protection for the stable operation of the pneumatic escape device, but also cope with various complex usage scenarios. It has the characteristics of precise control, energy saving and high efficiency, safety and reliability, and provides a solid guarantee for the application and promotion of pneumatic escape devices. From the multiple dimensions of equipment performance, user experience and safety, it improves rescue efficiency and operational safety.
