Description

Technical Field

[0001] This application relates to the field of oxygen mask communication technology, and in particular to an oxygen supply control method, device, medium and product that integrates voice communication function. Background Technology

[0002] With increasingly stringent safety requirements in special working environments, oxygen supply equipment is being used more and more widely in fields such as fire rescue, chemical rescue, and mining operations. To ensure the personal safety and work efficiency of personnel, oxygen supply equipment not only needs to guarantee reliable oxygen supply but also needs to enable real-time communication with ground command personnel.

[0003] Currently, oxygen supply and communication functions for workers are mainly achieved in two ways: one is by wearing separate oxygen supply and communication devices, and the other is by integrating the communication function into the oxygen supply mask. The former suffers from numerous devices, inconvenient operation, and can restrict worker movement in confined spaces, increasing safety hazards. The latter uses an integrated oxygen supply mask, which includes a communication module, microphone, and speaker. The mask connects to the oxygen supply device via an air intake pipe to provide oxygen, while the microphone and speaker are installed inside the mask and connected to the communication module via a data cable, thus integrating oxygen supply and communication functions.

[0004] However, since the microphone and speaker are directly installed inside the oxygen supply mask, they are directly impacted by the airflow during the oxygen supply process. Especially during high-flow oxygen supply, this generates significant airflow noise, affecting the communication between operators and ground command personnel. As a result, the oxygen supply mask cannot maintain good communication quality during the oxygen supply process, leading to poor communication quality of the oxygen supply mask in related technologies. Summary of the Invention

[0005] This application provides an oxygen supply control method, device, medium, and product with integrated communication function, used to improve the communication quality of oxygen supply masks during the oxygen supply process.

[0006] In a first aspect, this application provides an oxygen supply control method for integrated voice communication, applied to the aforementioned electronic device. The method includes: when a voice signal is detected within a target mask, acquiring respiratory airflow field distribution parameters and oxygen concentration parameters within the target mask; determining a high-intensity airflow zone and a low-intensity airflow zone based on the respiratory airflow field distribution parameters, and determining the oxygen supply demand based on the oxygen concentration parameters; directing the oxygen supply flow into the high-intensity airflow zone according to the oxygen supply demand, and constructing a voice transmission channel in the low-intensity airflow zone; adjusting the flow parameters of the oxygen supply flow within the high-intensity airflow zone to generate a vortex airflow layer, wherein the vortex airflow layer is used to isolate the voice transmission channel; and real-time monitoring of the oxygen concentration in the high-intensity airflow zone to transmit the voice signal from the voice transmission channel to the target receiving end.

[0007] By employing the above technical solution, when a voice signal is detected within the target mask, respiratory airflow distribution parameters and oxygen concentration parameters are collected. Based on the respiratory airflow distribution parameters, high-intensity and low-intensity airflow zones are distinguished, and a voice transmission channel is constructed within the low-intensity airflow zone. By adjusting the flow parameters of the oxygen supply flow in the high-intensity airflow zone to generate a vortex airflow layer that isolates the voice transmission channel, dynamic shielding of the voice transmission channel can be achieved. Simultaneously, by real-time monitoring of the oxygen concentration in the high-intensity airflow zone, the transmission quality of the voice signal can be ensured, guaranteeing both oxygen supply effectiveness and preventing interference from the oxygen supply flow to voice transmission, thus achieving dynamic isolation between the oxygen supply flow and the voice signal. This solves the technical problem of poor communication quality in oxygen supply masks during oxygen supply in related technologies, achieving the technical effect of improving the communication quality of oxygen supply masks during oxygen supply.

[0008] Optionally, the high-intensity airflow zone and the low-intensity airflow zone are determined based on the respiratory airflow field distribution parameters. Specifically, this includes: collecting a sequence of airflow intensity distribution maps for multiple respiratory cycles within a preset time window, wherein the respiratory airflow field distribution parameters include the sequence of airflow intensity distribution maps; overlaying the sequence of airflow intensity distribution maps to obtain an overlay airflow intensity map; dividing the internal space of the target mask into multiple detection areas; determining the airflow fluctuation intensity of each detection area within the preset time window based on the overlay airflow intensity map; marking a first detection area with an airflow fluctuation intensity less than a first preset fluctuation threshold as a low-intensity airflow zone, wherein the multiple detection areas include the first detection area; and marking a second detection area with an airflow fluctuation intensity greater than a second preset fluctuation threshold as a high-intensity airflow zone, wherein the multiple detection areas include the second detection area.

[0009] By employing the above technical solution, airflow intensity distribution sequences from multiple respiratory cycles within a preset time window are collected and overlaid to obtain an airflow intensity overlay map. The internal space of the target mask is divided into multiple detection areas, and the airflow fluctuation intensity of each detection area is determined based on the airflow intensity overlay map. By marking areas with airflow fluctuation intensity less than a first preset fluctuation threshold as low-intensity airflow areas and areas with airflow fluctuation intensity greater than a second preset fluctuation threshold as high-intensity airflow areas, accurate identification of the airflow distribution inside the target mask is achieved, providing an accurate basis for subsequent airflow control based on area division.

[0010] Optionally, the oxygen supply demand is determined based on oxygen concentration parameters, specifically including: determining a first oxygen concentration change rate within a preset time window in a low-intensity airflow region, wherein the oxygen concentration parameters include the first oxygen concentration change rate; determining a second oxygen concentration change rate within a preset time window in a high-intensity airflow region, wherein the oxygen concentration parameters include the second oxygen concentration change rate; determining an oxygen concentration compensation coefficient based on the first and second oxygen concentration change rates; and determining the oxygen supply demand based on the oxygen concentration compensation coefficient and a preset baseline oxygen supply.

[0011] By employing the above technical solution, the oxygen concentration change rate within a preset time window is determined for both the low-intensity and high-intensity airflow zones. An oxygen concentration compensation coefficient is then determined based on these two rates. Combined with a preset baseline oxygen supply, the oxygen demand is determined, enabling precise control of the oxygen supply. By monitoring oxygen concentration changes in different zones in real time and dynamically adjusting the oxygen supply, the oxygen supply process becomes more precise and controllable, thereby ensuring the oxygen needs of the workers are met.

[0012] Optionally, the oxygen supply flow is directed into the high-intensity airflow zone according to the oxygen supply demand, and a voice transmission channel is constructed in the low-intensity airflow zone. Specifically, this includes: determining the first spatial location information of the low-intensity airflow zone based on the first detection area; determining the second spatial location information of the high-intensity airflow zone based on the second detection area; determining the first position setting information of the oxygen supply guide channel within the high-intensity airflow zone based on the second spatial location information; adjusting the opening of the oxygen supply valve according to the first position setting information to ensure that the oxygen supply flow is directed into the oxygen supply guide channel according to the oxygen supply demand; determining the second position setting information of the voice acquisition device based on the first spatial location information; and constructing a voice transmission channel based on the second position setting information. The voice transmission channel includes an input channel for acquiring voice signals and an output channel for transmitting voice signals.

[0013] By adopting the above technical solution, the first spatial location information of the low-intensity airflow zone and the second spatial location information of the high-intensity airflow zone are determined according to the first and second detection areas, respectively. Based on these spatial location information, the first position setting information of the oxygen supply guide channel and the second position setting information of the voice acquisition device are determined, thereby adjusting the opening of the oxygen supply valve and constructing a voice transmission channel that includes an inlet channel and an outlet channel. This optimizes the spatial layout of the oxygen supply flow and the voice transmission channel, ensuring the effective separation of the oxygen supply function and the voice transmission function in physical space.

[0014] Optionally, the flow parameters of the oxygen supply flow are adjusted in the high-intensity airflow region to generate a vortex airflow layer. Specifically, this includes: determining the rotation axis of the oxygen supply flow based on the first position setting information and the second position setting information; adjusting the tangential and axial flow velocities of the oxygen supply flow along the rotation axis to make the oxygen supply flow flow in a spiral shape; and adjusting the rotation speed of the oxygen supply flow when it is determined that the oxygen supply flow flows in a spiral shape to form a vortex airflow layer in the high-intensity airflow region.

[0015] By adopting the above technical solution, the rotation axis of the oxygen supply flow is determined based on the first position setting information of the oxygen supply guide channel and the second position setting information of the voice acquisition device. The tangential and axial flow velocities of the oxygen supply flow are adjusted to induce a spiral flow. Adjusting the rotation speed of the oxygen supply flow creates a vortex airflow layer in the high-intensity airflow region. This vortex airflow layer effectively blocks airflow disturbances, providing a stable isolation barrier for the voice transmission channel.

[0016] Optionally, the oxygen concentration in the high-intensity airflow zone is monitored in real time to transmit the voice signal from the voice transmission channel to the target receiver. Specifically, this includes: real-time detection of the oxygen concentration in the high-intensity airflow zone; comparison of the oxygen concentration with a preset standard oxygen concentration to obtain the oxygen concentration deviation; determination of the isolation status of the vortex airflow layer based on the oxygen concentration deviation; determination of the signal transmission time window of the voice transmission channel based on the isolation status; and transmission of the voice signal from the voice transmission channel to the target receiver within the signal transmission time window.

[0017] By employing the above technical solution, the oxygen concentration in the high-intensity airflow zone is detected in real time and compared with a preset standard oxygen concentration. The isolation status of the vortex airflow layer is determined based on the oxygen concentration deviation. The signal transmission time window for the voice transmission channel is determined based on the isolation status, and the voice signal is transmitted within the optimal time window. The isolation effect is evaluated by monitoring oxygen concentration, and the best signal transmission timing is selected to further improve the quality of voice transmission.

[0018] Optionally, if a voice signal is detected inside the target mask, respiratory airflow distribution parameters and oxygen concentration parameters inside the target mask are collected. Specifically, this includes: deploying airflow parameter sensors and voice detection sensors inside the target mask; collecting the voice signal detected by the voice detection sensors; performing voiceprint feature extraction processing on the voice signal to determine whether there is voice input from the target object; and, if it is determined that there is voice input from the target object, continuously collecting respiratory airflow distribution parameters and oxygen concentration parameters inside the target mask during the voice input process.

[0019] By employing the above technical solution, airflow parameter sensors and voice detection sensors are deployed inside the target mask. The detected voice signals are processed to extract voiceprint features, determining whether there is voice input from the target object. After confirming voice input, respiratory airflow distribution parameters and oxygen concentration parameters are continuously collected, achieving accurate recognition of voice signals and intelligent triggering of parameter acquisition. This avoids unnecessary data collection and processing, improving overall operational efficiency.

The oxygen supply control method for the integrated call function provided in this application collects respiratory airflow field distribution parameters and oxygen concentration parameters when a voice signal is detected inside the target mask. Based on the respiratory airflow field distribution parameters, it distinguishes between high-intensity and low-intensity airflow zones and constructs a voice transmission channel in the low-intensity airflow zone. By adjusting the flow parameters of the oxygen supply flow in the high-intensity airflow zone to generate a vortex airflow layer to isolate the voice transmission channel, dynamic shielding of the voice transmission channel can be achieved. Simultaneously, by real-time monitoring of the oxygen concentration in the high-intensity airflow zone, the transmission quality of the voice signal can be ensured, guaranteeing both oxygen supply effectiveness and preventing interference from the oxygen supply flow to voice transmission, thereby achieving dynamic isolation between the oxygen supply flow and the voice signal.

[0024] 2. The oxygen supply control method for the fusion communication function provided in this application collects and overlays airflow intensity distribution map sequences of multiple breathing cycles within a preset time window to obtain an airflow intensity overlay map. The internal space of the target mask is divided into multiple detection areas, and the airflow fluctuation intensity of each detection area is determined according to the airflow intensity overlay map. By marking areas with airflow fluctuation intensity less than a first preset fluctuation threshold as low-intensity airflow areas and areas with airflow fluctuation intensity greater than a second preset fluctuation threshold as high-intensity airflow areas, accurate identification of the airflow distribution inside the target mask is achieved, providing an accurate basis for subsequent airflow control based on area division.

[0025] 3.

[0029] This application provides an oxygen supply control method for integrated call functionality, see reference. Figure 1 , Figure 1 This is a flowchart illustrating an oxygen supply control method for integrating call functionality in an embodiment of this application, comprising the following steps: Step S101: When a voice signal is detected inside the target mask, collect the respiratory airflow field distribution parameters and oxygen concentration parameters inside the target mask; Step S102: Determine the high-intensity airflow zone and the low-intensity airflow zone based on the respiratory airflow field distribution parameters, and determine the oxygen supply demand based on the oxygen concentration parameters. Step S103: According to the oxygen supply demand, the oxygen supply flow is directed into the high-intensity airflow zone, and a voice transmission channel is built in the low-intensity airflow zone. Step S104: Adjust the flow parameters of the oxygen supply flow in the high-intensity airflow zone to generate a vortex airflow layer, wherein the vortex airflow layer is used to isolate the voice transmission channel. Step S105: Real-time monitoring of oxygen concentration in the high-intensity airflow zone is performed to transmit the voice signal from the voice transmission channel to the target receiving end.

[0030] In the above embodiments, the target mask is a sealed breathing device or equipment that provides oxygen supply to the user; the voice signal refers to the sound wave signal generated by the user's voice inside the mask; the breathing airflow field distribution parameter represents the distribution characteristics of the airflow intensity and direction generated by the user's breathing behavior inside the mask; the oxygen concentration parameter refers to the oxygen content level in different areas inside the mask; the high-intensity airflow area represents the detection area where the airflow fluctuation intensity is greater than a second preset fluctuation threshold; the low-intensity airflow area represents the detection area where the airflow fluctuation intensity is less than a first preset fluctuation threshold; the voice transmission channel refers to the path used to transmit the voice signal; the vortex airflow layer refers to the barrier layer formed by the spirally rotating airflow; and the target receiving end refers to the voice signal receiving device. The oxygen supply flow refers to the airflow output from the oxygen supply device to provide the oxygen required for breathing; the flow parameter represents the comprehensive parameters of the physical characteristics of the airflow, such as speed, pressure, and direction.

[0031] In the above embodiment, it is assumed that eight airflow parameter sensors and two oxygen concentration sensors are installed inside the target mask. Considering the structural characteristics of the human face and the distribution pattern of respiratory airflow, four airflow parameter sensors are arranged within a 120-degree range on both sides of the nostrils, with a sensor spacing of 30 degrees; four airflow parameter sensors are evenly arranged within the remaining 240-degree range, with a sensor spacing of 60 degrees. The two oxygen concentration sensors are located in the upper breathing zone and the lower exhalation zone of the mask, respectively. When the voice detection sensor detects a voice signal, the airflow parameter sensors collect respiratory airflow field data at a sampling frequency of 20Hz, and the oxygen concentration sensors collect oxygen concentration data at a sampling frequency of 1Hz. After collecting data for three complete respiratory cycles (approximately 12 seconds, calculated based on a respiratory rate of 15 breaths / min), the airflow intensity distribution map is generated from the data obtained by the airflow parameter sensors. Based on facial anatomical features and respiratory airflow dynamics, the interior of the mask is divided into eight non-uniform fan-shaped detection areas: four fan-shaped detection areas on both sides of the nostrils, each area being 30 degrees, totaling 120 degrees; and the remaining four fan-shaped detection areas, each 60 degrees, totaling 240 degrees. By calculating the airflow fluctuation intensity in each region, areas with airflow fluctuation intensity below 0.3 m / s are marked as low-intensity airflow zones, and areas with airflow fluctuation intensity above 0.6 m / s are marked as high-intensity airflow zones. Simultaneously, based on data collected by oxygen concentration sensors, when the oxygen concentration detected by any sensor is below 20%, the oxygen supply demand is set to 6 L / min.

[0032] In the above embodiment, an oxygen supply guide channel with a diameter of 8mm is installed in the determined high-intensity airflow zone, and the channel inlet is connected to the oxygen supply valve. The oxygen supply guide channel is made of medical-grade silicone material with appropriate flexibility. Two voice acquisition devices are arranged in the low-intensity airflow zone. The pickup head of the acquisition device has a diameter of 5mm, and the distance between the two devices is set to 50mm. The opening of the oxygen supply valve is automatically adjusted according to the oxygen demand and the oxygen supply pipeline pressure (0.2MPa under standard conditions). The inner wall of the oxygen supply guide channel is provided with a spiral guide vane with a spiral angle of 45 degrees and a pitch of 16mm. The tangential flow velocity of the oxygen supply flow is adjusted to 1.2m / s and the axial flow velocity to 0.8m / s by the guide vane structure, so that the oxygen supply flow forms a spiral flow. When the rotational speed of the oxygen supply flow stabilizes at 40rad / s, a stable vortex airflow layer is formed in the high-intensity airflow zone, and the thickness of the vortex airflow layer is approximately 15mm. An oxygen concentration sensor is used to monitor the oxygen concentration in the high-intensity airflow zone in real time at a frequency of 1Hz. When the detected oxygen concentration deviates from the preset standard oxygen concentration (21%) within ±0.5% for more than 2 seconds, the vortex airflow layer is confirmed to be in a stable isolation state. At this time, a signal transmission time window (20ms duration) is opened, and the voice signal is transmitted from the voice transmission channel to the target receiver. If the oxygen concentration deviation exceeds the range, the system will automatically adjust the oxygen supply parameters within 200ms. Through the above specific implementation method, the oxygen concentration in the high-intensity airflow zone can be stably maintained within the range of 20.5% to 21.5%, the voice signal recognition accuracy reaches over 95%, and the airflow noise is below 30dB, a reduction of 80% compared to when no vortex airflow layer isolation is used. Furthermore, the time from detecting the voice signal to establishing a stable call state does not exceed 2 seconds. It should also be noted that the examples of the actual values ​​of the above parameters are merely exemplary embodiments, and the actual values ​​of the parameters are not limited to the examples above, and can be adjusted according to specific needs in practical applications.

[0033] Through the above steps, when a voice signal is detected inside the target mask, respiratory airflow distribution parameters and oxygen concentration parameters are collected. Based on the respiratory airflow distribution parameters, high-intensity and low-intensity airflow zones are distinguished, and a voice transmission channel is constructed in the low-intensity airflow zone. By adjusting the flow parameters of the oxygen supply flow in the high-intensity airflow zone to generate a vortex airflow layer to isolate the voice transmission channel, dynamic shielding of the voice transmission channel can be achieved. Simultaneously, by monitoring the oxygen concentration in the high-intensity airflow zone in real time, the transmission quality of the voice signal can be ensured, guaranteeing both oxygen supply effectiveness and preventing interference from the oxygen supply flow to voice transmission, thus achieving dynamic isolation between the oxygen supply flow and the voice signal. This solves the technical problem of poor communication quality of oxygen supply masks during oxygen supply in related technologies, achieving the technical effect of improving the communication quality of oxygen supply masks during oxygen supply.

[0034] The entity performing the above steps may be a system or device with oxygen supply and communication capabilities, such as an oxygen supply mask, or a controller or processor in the device or system, or a standalone controller or processor, or other processing devices or processing units with similar processing functions, but is not limited to these.

[0035] In an optional embodiment, determining high-intensity and low-intensity airflow regions based on respiratory airflow field distribution parameters specifically includes: acquiring a sequence of airflow intensity distribution maps for multiple respiratory cycles within a preset time window, wherein the respiratory airflow field distribution parameters include the sequence of airflow intensity distribution maps; overlaying the sequence of airflow intensity distribution maps to obtain an overlay airflow intensity map; dividing the internal space of the target mask into multiple detection areas; determining the airflow fluctuation intensity of each detection area within the preset time window based on the overlay airflow intensity map; marking a first detection area with an airflow fluctuation intensity less than a first preset fluctuation threshold as a low-intensity airflow region, wherein the multiple detection areas include the first detection area; and marking a second detection area with an airflow fluctuation intensity greater than a second preset fluctuation threshold as a high-intensity airflow region, wherein the multiple detection areas include the second detection area.

[0036] In the above embodiments, the preset time window represents a pre-set continuous sampling time; the breathing cycle refers to the time interval between one inhalation and exhalation by the user of the target mask; the airflow intensity distribution map sequence refers to a set of distribution maps formed in chronological order, recording the distribution of airflow intensity at various locations inside the mask during each breathing cycle; the airflow intensity overlay map refers to a statistical characteristic map of airflow intensity in multiple detection areas obtained by overlaying and averaging the airflow intensity data of the same detection area over multiple breathing cycles; multiple detection areas represent several independent regional units obtained by dividing the internal space of the target mask; airflow fluctuation intensity refers to the variation range of airflow intensity within a specific area; the first preset fluctuation threshold and the second preset fluctuation threshold represent the upper and lower limit reference values ​​used to divide the airflow intensity areas, respectively. The first detection area represents the detection area marked as a low-intensity airflow area; the second detection area represents the detection area marked as a high-intensity airflow area.

[0037] In the above embodiment, high-intensity and low-intensity airflow zones are determined based on respiratory airflow field distribution parameters. A preset time window is set to 10 seconds. Based on a normal human respiratory rate of 15 breaths / min, airflow intensity distribution map sequences for three complete respiratory cycles can be collected. Twelve airflow parameter sensors are positioned at the edge of the target mask. Considering the structural characteristics of the human face and the distribution pattern of respiratory airflow, six sensors are positioned within a 120-degree range on both sides of the nostrils, spaced 20 degrees apart. Six sensors are evenly distributed within the remaining 240-degree range, spaced 40 degrees apart. The airflow parameter sensors sample at a frequency of 20Hz. Each sensor collects approximately 80 data points per respiratory cycle, totaling approximately 240 data points over three respiratory cycles, forming the airflow intensity distribution map sequence. After collecting the airflow intensity distribution map sequence, it is averaged. A regional cumulative averaging method is used, summing the airflow intensity data collected by each airflow parameter sensor location within the entire preset time window and dividing by the number of sampling points to obtain the average airflow intensity value for that location. Based on the average airflow intensity values ​​from 12 airflow parameter sensors, a superimposed airflow intensity map covering the entire internal space of the mask is generated using a cubic spline interpolation algorithm. The internal space of the target mask is divided into 8 non-uniform fan-shaped detection regions. Four fan-shaped detection regions are set on both sides of the nostrils, each region being 30 degrees, totaling 120 degrees. The remaining four fan-shaped detection regions are each 60 degrees, totaling 240 degrees. This fan-shaped detection region division scheme ensures that each detection region has at least one sensor providing direct data. The key areas on both sides of the nostrils are configured with 1-2 sensors per detection region, maintaining data continuity between adjacent regions.

[0038] In the above embodiment, the airflow fluctuation intensity is calculated within each fan-shaped detection area. The airflow fluctuation intensity is calculated as follows: Sampling data from all airflow parameter sensors within the fan-shaped detection area are taken within a preset time window. The root mean square deviation (RMS) of the sampled data relative to the average value is calculated, and this RMS deviation is used as the airflow fluctuation intensity of the fan-shaped detection area. Fan-shaped detection areas with airflow fluctuation intensity less than 0.25 m / s are marked as low-intensity airflow areas (first detection area); fan-shaped detection areas with airflow fluctuation intensity greater than 0.5 m / s are marked as high-intensity airflow areas (second detection area). The airflow fluctuation intensity thresholds of 0.25 m / s and 0.5 m / s are determined based on the airflow change characteristics within the mask during normal human breathing. 0.25 m / s corresponds to the airflow fluctuation level during calm breathing, and 0.5 m / s corresponds to the airflow fluctuation level during forced breathing. Through the above specific implementation method, airflow distribution identification and area division within the mask can be completed within a preset time window of 10 seconds. The spatial resolution reaches 30 degrees in key areas on both sides of the nostrils, and 60 degrees in other areas. The calculation error of airflow fluctuation intensity is controlled within ±0.02 m / s. This non-uniform region division scheme correctly identifies the airflow distribution characteristics within the mask in over 98% of cases, providing a stable and reliable basis for region division for oxygen supply control and voice transmission. It should also be noted that the examples of the actual values ​​of the above parameters are merely exemplary embodiments, and the actual values ​​of the parameters are not limited to the examples given above, and can be adjusted according to specific needs in practical applications.

[0039] In an optional embodiment, determining the oxygen supply demand based on oxygen concentration parameters specifically includes: determining a first oxygen concentration change rate within a preset time window in a low-intensity airflow region, wherein the oxygen concentration parameter includes the first oxygen concentration change rate; determining a second oxygen concentration change rate within a preset time window in a high-intensity airflow region, wherein the oxygen concentration parameter includes the second oxygen concentration change rate; determining an oxygen concentration compensation coefficient based on the first and second oxygen concentration change rates; and determining the oxygen supply demand based on the oxygen concentration compensation coefficient and a preset baseline oxygen supply.

[0040] In the above embodiments, the first oxygen concentration change rate represents the ratio of the change in oxygen concentration in the low-intensity airflow region to time within a preset time window; the second oxygen concentration change rate represents the ratio of the change in oxygen concentration in the high-intensity airflow region to time within a preset time window; the oxygen concentration compensation coefficient refers to the correction parameter used to adjust the oxygen supply, calculated based on the first and second oxygen concentration change rates; the preset baseline oxygen supply represents the basic oxygen supply flow rate preset under standard conditions; and the oxygen supply demand refers to the actual required oxygen supply flow rate obtained after adjustment by the compensation coefficient.

[0041] In the above embodiment, the oxygen demand is determined based on the oxygen concentration parameter. A preset time window is set to 6 seconds. One oxygen concentration sensor is placed in each of the low-intensity and high-intensity airflow zones within the target mask, with a sampling frequency of 5Hz. Each oxygen concentration sensor in both zones collects 30 data points within the preset time window. The oxygen concentration change trend is calculated using the least squares method to accurately reflect the changes in oxygen demand in different zones. The 30 data points collected from the oxygen concentration sensor in the low-intensity airflow zone within 6 seconds are fitted using the least squares method to obtain the rate of change of oxygen concentration over time, determining the first oxygen concentration change rate. For example, when the oxygen concentration decreases from 21% to 20.9% within 6 seconds, the first oxygen concentration change rate is calculated as -0.017% / s. The same method is used to process the data from the oxygen concentration sensor in the high-intensity airflow zone to obtain the second oxygen concentration change rate. For example, when the oxygen concentration decreases from 21% to 20.7% within 6 seconds, the second oxygen concentration change rate is calculated as -0.05% / s. An oxygen concentration compensation coefficient is determined based on the ratio of the oxygen concentration change rates of the two zones. The specific calculation method is as follows: when the absolute ratio of the oxygen concentration change rates of the two regions is not greater than 1.5, the compensation coefficient is set to 1.0; when the ratio is greater than 1.5 but not greater than 2.5, the compensation coefficient is set to 1.2; when the ratio is greater than 2.5, the compensation coefficient is set to 1.5. |Second Change Rate / First Change Rate| = 2.94 (|-0.05% / s| / |-0.017% / s| = 2.94), which is greater than 2.5, therefore the compensation coefficient is determined to be 1.5. The preset baseline oxygen supply is set to 5 L / min. Multiplying the preset baseline oxygen supply by the oxygen concentration compensation coefficient yields an oxygen demand of 7.5 L / min. This oxygen demand falls within the reasonable oxygen supply range of 3–8 L / min, meeting actual usage requirements. The oxygen supply is precisely controlled in 0.5 L / min adjustment steps. Through the above specific implementation method, accurate calculation and dynamic adjustment of the oxygen demand can be achieved. A 5Hz sampling frequency and a 6-second time window ensure data reliability and timely response, while the segmented compensation coefficient calculation method effectively avoids over-compensation of oxygen supply. In practical applications, the preset baseline oxygen supply can be personalized according to the user's physical condition and activity intensity, and the calculation method of the oxygen concentration compensation coefficient can also be optimized according to actual needs. It should also be noted that the examples of the actual values ​​of the above parameters are merely exemplary embodiments, and the actual values ​​of the above parameters are not limited to the examples given above, and can be adjusted according to specific needs in practical applications.

[0042] In an optional embodiment, the oxygen supply flow is directed into a high-intensity airflow zone according to the oxygen supply demand, and a voice transmission channel is constructed in a low-intensity airflow zone. Specifically, this includes: determining first spatial location information of the low-intensity airflow zone based on a first detection area; determining second spatial location information of the high-intensity airflow zone based on a second detection area; determining first position setting information of the oxygen supply guide channel within the high-intensity airflow zone based on the second spatial location information; adjusting the opening of the oxygen supply valve according to the first position setting information to direct the oxygen supply flow into the oxygen supply guide channel according to the oxygen supply demand; determining second position setting information of the voice acquisition device based on the first spatial location information; and constructing a voice transmission channel based on the second position setting information. The voice transmission channel includes an input channel for acquiring voice signals and an output channel for transmitting voice signals.

[0043] In the above embodiments, the first spatial location information represents the relative positional relationship and regional distribution range of the low-intensity airflow zone inside the target mask; the second spatial location information represents the relative positional relationship and regional distribution range of the high-intensity airflow zone inside the target mask; the oxygen supply guide channel refers to a specific channel used to guide the flow of oxygen supply; the first location setting information represents parameters such as the installation position and orientation of the oxygen supply guide channel within the high-intensity airflow zone; the oxygen supply valve refers to a regulating device used to control the flow rate of the oxygen supply; the voice acquisition device represents a sensor device used to acquire voice signals; the second location setting information represents parameters such as the installation position and orientation of the voice acquisition device within the low-intensity airflow zone; the sound inlet channel refers to a channel used to acquire the user's voice; and the sound outlet channel refers to a channel that transmits the acquired voice signals outward.

[0044] In the above embodiment, the oxygen supply flow is directed into the high-intensity airflow zone according to the oxygen demand, and a voice transmission channel is constructed in the low-intensity airflow zone. First, the spatial location information of each zone is determined using data collected by airflow parameter sensors. Based on the division of eight non-uniform fan-shaped detection zones within the mask, the first detection zone of the low-intensity airflow zone is located within a 60-120 degree range on the left side of the mask, with an airflow fluctuation intensity of 0.15% / s; the second detection zone of the high-intensity airflow zone is located within a 240-300 degree range on the right side of the mask, with an airflow fluctuation intensity of 0.65% / s. Based on the location information of the high-intensity airflow zone determined by the second detection zone, the layout scheme of the oxygen supply guiding channel is designed. The oxygen supply guiding channel uses a 10mm inner diameter medical-grade silicone tube, with the inlet end connected to the oxygen supply valve and the outlet end located at the center of the high-intensity airflow zone, i.e., 270 degrees on the right side of the mask. A spiral guide vane is installed on the inner wall of the channel, with a spiral angle of 45 degrees and a pitch of 16mm. When the oxygen demand is 7.5L / min, based on the standard pressure of the oxygen supply pipeline of 0.2MPa and the cross-sectional area of ​​the channel of 78.54mm², the opening of the oxygen supply valve should be set to 50%. At this time, the tangential velocity of the oxygen supply flow is 1.1m / s, the axial velocity is 0.9m / s, and the total velocity is about 1.42m / s.

[0045] In the above embodiment, based on the location information of the low-intensity airflow zone determined by the first detection area, two voice acquisition devices are arranged at a 90-degree angle to the left of the mask. The pickup head of the acquisition device has a diameter of 5mm, and the distance between the two devices is set to 50mm. The voice transmission channel consists of an inlet channel and an outlet channel: the inlet channel uses a 5mm inner diameter sound guide tube, which is directly connected to the pickup head; the outlet channel uses a 6mm inner diameter transmission tube, one end of which is connected to the voice processing module, and the other end extends to the communication device outside the mask. Both the inlet and outlet channels are made of sound-attenuating material with a wall thickness of 2mm. Through the above specific implementation method, effective isolation between the oxygen supply flow and the voice signal can be achieved. Under the condition of an oxygen supply demand of 7.5L / min, a stable vortex airflow layer with a thickness of about 15mm is formed in the high-intensity airflow zone, maintaining the oxygen concentration in this area within the range of 20.5% to 21.5%. The voice acquisition device in the low-intensity airflow zone can stably acquire voice signals, with a transmission intelligibility rate of over 95%, and the airflow noise is below 30dB. The response time is no more than 2 seconds, and the oxygen supply adjustment accuracy reaches 0.5L / min, meeting practical usage requirements. It should also be noted that the examples of the above parameters are merely illustrative embodiments; the actual values ​​are not limited to these examples and can be adjusted according to specific needs in actual applications.

[0046] In an optional embodiment, adjusting the flow parameters of the oxygen supply flow within the high-intensity airflow region to generate a vortex airflow layer specifically includes: determining the rotation axis of the oxygen supply flow based on first and second position setting information; adjusting the tangential and axial flow velocities of the oxygen supply flow along the rotation axis to make the oxygen supply flow flow in a spiral shape; and, when the oxygen supply flow is determined to flow in a spiral shape, adjusting the rotation speed of the oxygen supply flow to form a vortex airflow layer within the high-intensity airflow region.

[0047] In the above embodiments, the axis of rotation refers to the central axis when the oxygen supply flow forms a vortex motion; the tangential velocity refers to the velocity component of the airflow moving in a circle around the axis of rotation; the axial velocity refers to the velocity component of the airflow moving along the direction of the axis of rotation; the spiral flow refers to the flow state in which the airflow has both rotation and axial motion; the rotational speed refers to the angular velocity of the oxygen supply flow rotating around the axis of rotation; and the vortex airflow layer refers to the fluid layer with an isolating effect formed by the spiral airflow.

[0048] In the above embodiment, the flow parameters of the oxygen supply flow are adjusted within the high-intensity airflow zone to generate a vortex airflow layer. The rotation axis of the oxygen supply flow is determined based on the location information of the oxygen supply guide channel. The outlet of the oxygen supply guide channel is located 270 degrees to the right of the mask, with the channel centerline making a 60-degree angle with the mask surface, and the rotation axis coinciding with the channel centerline. The channel inner diameter is 10 mm, and a spiral guide vane is installed on the inner wall of the channel. The spiral angle of the guide vane is 45 degrees, and the pitch is 16 mm. When the oxygen supply demand is 7.5 L / min, the airflow motion is controlled by adjusting the structural parameters of the guide vane. The oxygen supply flow is decomposed into tangential and axial components within the channel by the guide vane; the tangential velocity is set to 1.2 m / s, and the axial velocity is set to 1.0 m / s. The total airflow velocity is √(1.2² + 1.0²) ≈ 1.56 m / s, and its matching relationship with the oxygen demand and channel cross-sectional area is 7.5 L / min = 125 mL / s = 1.56 m / s × π × (5 mm)² = 125000 mm³ / s. After exiting the guide channel, the airflow forms a spiral flow under the action of centrifugal force and Coriolis force. To ensure the stability of the vortex airflow layer, the rotational speed of the oxygen supply flow needs to be precisely controlled. Based on the channel geometry and airflow velocity, the initial rotational angular velocity ω = tangential velocity / channel radius = 1.2 m / s ÷ 0.005 m = 240 rad / s is calculated. Considering airflow diffusion and energy loss of about 40%, the actual rotational speed at the channel outlet is approximately 144 rad / s. At this point, the characteristic parameters of the vortex airflow layer are: vortex airflow layer thickness 15mm, vortex airflow layer outer diameter 35mm, vortex airflow layer inner diameter 20mm, and vortex airflow layer radial velocity gradient 0.1 (m / s) / mm. Under these parameter configurations, the vortex airflow layer exhibits good stability and isolation effect. The vortex airflow layer can sustainably maintain a stable state, with the oxygen concentration in the high-intensity airflow zone remaining within the range of 20.5% to 21.5%, effectively isolating it from the surrounding environment. Test results show that the formation time of the vortex airflow layer does not exceed 0.5 seconds, and the stability index is better than 90%. The airflow parameters can be automatically adjusted according to changes in oxygen demand to ensure the dynamic stability of the vortex airflow layer. It should also be noted that the examples of the actual values ​​of the above parameters are merely exemplary embodiments, and the actual values ​​of the parameters are not limited to the examples given above, and can be adjusted according to specific needs in practical applications.

[0049] In an optional embodiment, the oxygen concentration in the high-intensity airflow zone is monitored in real time to transmit the voice signal from the voice transmission channel to the target receiver. Specifically, this includes: real-time detection of the oxygen concentration in the high-intensity airflow zone; comparing the oxygen concentration with a preset standard oxygen concentration to obtain the oxygen concentration deviation; determining the isolation state of the vortex airflow layer based on the oxygen concentration deviation; determining the signal transmission time window of the voice transmission channel based on the isolation state; and transmitting the voice signal from the voice transmission channel to the target receiver within the signal transmission time window.

[0050] In the above embodiments, oxygen concentration represents the actual oxygen content per unit volume of air in the high-intensity airflow zone; preset standard oxygen concentration represents a pre-set reference value for oxygen content; oxygen concentration deviation represents the difference between the actual oxygen concentration and the preset standard oxygen concentration; isolation state represents the isolation effect of the vortex airflow layer on the voice transmission channel; and signal transmission time window represents the time period suitable for voice signal transmission.

[0051] In the above embodiment, the oxygen concentration in the high-intensity airflow zone is monitored in real time to control the transmission of voice signals. An oxygen concentration sensor is installed in the high-intensity airflow zone, with a sampling frequency of 20Hz, collecting data every 50ms. The sensor's measurement accuracy is ±0.1%, and its response time is less than 25ms, enabling rapid and accurate measurement of oxygen concentration. The oxygen concentration sensor detects the oxygen concentration value in the high-intensity airflow zone in real time, and the system compares the detected oxygen concentration with a preset standard oxygen concentration of 21%. An oxygen concentration deviation threshold of ±0.5% is set, meaning that when the detected oxygen concentration is within the range of 20.5% to 21.5%, the oxygen concentration is considered to be within an acceptable range. The specific method for calculating the oxygen concentration deviation is as follows: using 21% as the baseline value, the difference between the measured value and the baseline value is calculated. For example, when the detected oxygen concentration is 20.8%, the oxygen concentration deviation is -0.2%. The isolation status of the vortex airflow layer is determined based on the continuously monitored oxygen concentration deviation. The specific determination method is as follows: when the oxygen concentration deviation remains within ±0.5% for 30 sampling points (i.e., 1.5 seconds), the vortex airflow layer is determined to be in a stable isolation state. If the oxygen concentration deviation exceeds ±0.5% during monitoring, the timing restarts. The isolation state determination result is updated every 50ms. Once the vortex airflow layer is confirmed to be in a stable isolation state, the signal transmission time window of the voice transmission channel is opened. The duration of the signal transmission time window is set to 20ms, the signal sampling rate is 44.1kHz, and 882 voice signal sampling points are collected in each transmission window. If the oxygen concentration deviation remains within the allowable range for three consecutive transmission windows (a total of 60ms), voice signal transmission continues; if the oxygen concentration deviation is detected to exceed the range, the transmission window is closed within 25ms. Through the above specific implementation method, stable and reliable voice signal transmission can be achieved. The oxygen concentration monitoring accuracy reaches ±0.1%, and the accuracy rate of vortex airflow layer isolation state determination exceeds 98%. Under normal call conditions, the voice signal transmission delay does not exceed 50ms, and the transmission recognizability reaches over 95%. When oxygen concentration becomes abnormal, the system's response time is less than 25ms, enabling timely interruption of signal transmission and preventing call quality degradation. It should also be noted that the examples of the above parameters are merely illustrative embodiments; the actual values ​​are not limited to these examples and can be adjusted according to specific needs in practical applications.

[0052] In an optional embodiment, when a voice signal is detected inside the target mask, respiratory airflow field distribution parameters and oxygen concentration parameters inside the target mask are collected. Specifically, this includes: deploying airflow parameter sensors and voice detection sensors inside the target mask; collecting the voice signal detected by the voice detection sensors; performing voiceprint feature extraction processing on the voice signal to determine whether there is voice input from the target object; and, if it is determined that there is voice input from the target object, continuously collecting respiratory airflow field distribution parameters and oxygen concentration parameters inside the target mask during the voice input process.

[0053] In the above embodiments, the airflow parameter sensor represents a detection device for collecting airflow characteristic data; the voice detection sensor represents an audio sensing device for collecting voice signals; the voiceprint feature represents acoustic features extracted from the voice signal to characterize the unique properties of the voice, including timbre, pitch, intensity, etc.; and the target object is the user of the target mask.

[0054] In the above embodiment, airflow parameter sensors and voice detection sensors are installed inside the target mask. Two voice detection sensors, employing electret condenser microphones with a frequency response range of 20Hz-20kHz, sensitivity of -38dB, and a signal-to-noise ratio greater than 65dB, are deployed inside the target mask. The two voice detection sensors are located on the left and right sides of the mask, respectively, at a distance of 40mm from the user's mouth. Simultaneously, eight airflow parameter sensors, employing thermal airflow sensors with a sensitivity of 0.01m / s and a response time of 20ms, are also deployed. The voice detection sensors acquire sound signals at a sampling rate of 44.1kHz. When the detected sound signal intensity exceeds -30dB, voiceprint feature extraction processing is initiated. Voiceprint feature extraction employs the MFCC method. The input speech signal undergoes pre-emphasis processing with a pre-emphasis coefficient of 0.97. Framing is then performed with a frame length of 20ms and a frame shift of 5ms. A Hamming window is applied to each frame, followed by a Fast Fourier Transform (FFT) to obtain the signal spectrum. This spectrum is then passed through a 24-Melbourne filter bank, logarithmic operations are performed, and a Discrete Cosine Transform (DCT) is conducted to extract the first 13 coefficients as the voiceprint feature vector. Voiceprint feature templates for the target object are pre-stored, and a Dynamic Time Warping (VTW) algorithm is used for feature matching. A matching threshold of 0.80 is set; when the feature matching degree exceeds the threshold, the speech input is confirmed as belonging to the target object. The feature matching computation time is less than 50ms, meeting real-time recognition requirements.

[0055] In the above embodiment, after confirming the presence of voice input from a target object, airflow parameter acquisition is initiated. Eight airflow parameter sensors synchronously acquire respiratory airflow field data at a sampling frequency of 20Hz, with a measurement range of 0-3m / s. Each sensor acquires one data point within 50ms, with a data resolution of 0.01m / s. The airflow field distribution parameters acquired by the system include airflow velocity, airflow direction, airflow fluctuation intensity, and airflow turbulence. The airflow velocity range is 0-3m / s with a resolution of 0.01m / s, the angular resolution of the airflow direction is 5 degrees, the airflow fluctuation intensity is expressed using the root mean square value, and the airflow turbulence is obtained by calculating the ratio of the pulsation velocity to the average velocity. Simultaneously, two oxygen concentration sensors acquire oxygen concentration data at a frequency of 20Hz, with a measurement range of 19%–23% and an accuracy of ±0.1%. The system calculates the concentration change rate every 50ms and the concentration distribution uniformity every 100ms. The system continuously acquires data until the voice input ends. Through the above specific implementation method, accurate recognition of the target object's voice and real-time acquisition of relevant parameters can be achieved. The voiceprint recognition accuracy reaches over 95%, with a false recognition rate of less than 1%. The acquisition delay for airflow parameters and oxygen concentration is no more than 50ms, and the data integrity exceeds 99%. Overall operation is stable and can meet the data requirements for subsequent oxygen supply control and voice transmission. It should also be noted that the examples of the above parameters are merely illustrative embodiments, and the actual values ​​of the parameters are not limited to the examples given above, and can be adjusted according to specific needs in practical applications.
