[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Some embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] With the increasing popularity of outdoor sports, more and more people are choosing to travel and explore high-altitude areas. However, the thin air at high altitudes easily triggers altitude sickness, posing a serious threat to travelers, especially those engaged in outdoor activities. Portable oxygen concentrators can help hikers avoid this situation as much as possible, but in actual use, because the battery life and the individual's physical condition during the hike cannot be monitored in real time, the oxygen concentrator's battery life may not meet the requirements of hiking, thus creating potential risks during the hike.

[0035] Therefore, how to reduce or avoid the risks to hikers caused by insufficient oxygen concentrator battery life is a pressing technical problem that needs to be solved in this field. In other words, existing technologies suffer from insufficient and inaccurate monitoring of the dynamic battery life of oxygen concentrators.

[0036] Based on this, embodiments of the present invention provide an oxygen concentrator endurance control method, system, and oxygen concentrator to solve the technical problems of insufficient timeliness and low accuracy in monitoring the dynamic endurance of oxygen concentrators in the prior art.

[0037] To facilitate understanding of this embodiment, a detailed description of an oxygen concentrator's battery life control method disclosed in this invention will be provided first. The execution entity of this method is generally a smart device with a certain computing capability. This smart device may include, for example, a terminal device or an oxygen concentrator device with human-computer interaction functionality. The terminal device can be a user equipment (UE), mobile device, user terminal, terminal, personal digital assistant (PDA), handheld device, wearable device, etc. In some possible implementations, the oxygen concentrator's battery life control method can be implemented by a processor calling readable instructions stored in memory.

[0038] See Figure 1 The diagram shows a flowchart of an oxygen concentrator's continuous operation control method, which mainly includes the following steps S110 to S140:

[0039] S110: Based on the oxygen concentrator parameters and the hiker's total oxygen demand, determine the initial power of the oxygen concentrator to meet the first hiking objective;

[0040] The first hiking objective includes the planned total hiking time; in one embodiment, the first hiking objective also includes the planned hiking route and the corresponding altitude.

[0041] Prior to S110 above, the method may further include:

[0042] (S01) Determine the total amount of oxygen that the oxygen generator can provide based on the oxygen generator parameters;

[0043] (S02) Calculate the oxygen requirement of the first hiking target based on the hiker's metabolic parameters;

[0044] The metabolic parameters include basal metabolic oxygen demand (BMD), activity metabolic oxygen demand (MDO), and compensatory oxygen consumption. In this embodiment, step (S02) includes: first, calculating the BMD based on the hiker's basal metabolic rate; then, calculating the MDO based on the BMD and the activity intensity coefficient; next, determining the compensatory oxygen consumption based on the sum of the BMD and the MDO; and finally, determining the oxygen requirement based on the BMD, the MDO, and the compensatory oxygen consumption.

[0045] (S03) Calculate the total oxygen requirement of the hiker based on the oxygen requirement and the planned total hiking time.

[0046] In one embodiment, the total oxygen requirement is equal to the oxygen requirement multiplied by the total hiking time (i.e., total oxygen requirement O). need = Oxygen requirement * Planned total hiking time T total Oxygen demand needs to take into account basal metabolic oxygen demand, activity metabolic oxygen demand and compensatory oxygen consumption (i.e.: oxygen demand = basal metabolic oxygen demand + activity metabolic oxygen demand + compensatory oxygen consumption).

[0047] in, Where: BMR 高海拔 The values ​​represent the basal metabolic rate at the corresponding altitude, 24 for a 24-hour day, and 60 for a 60-minute hour. The oxygen quotient is 4.825 kcal / L (when the respiratory quotient is 0.8).

[0048] It should be noted that when determining a hiker's route (the primary hiking goal), the path and altitude shown on the map can be used as a reference. Generally, for every 1000 meters increase in altitude, the basal metabolic rate (BMR) increases by approximately 5-10%, that is:

[0049] BMR 高海拔 =BMR 海平面 ×(1+0.05×h / 1000); where, BMR 高海拔 BMR represents the basal metabolic rate of a typical hiker at a given altitude. 海平面 This represents the basal metabolic rate of a typical hiker at sea level.

[0050] Activity metabolic oxygen demand = basal metabolic oxygen demand * activity intensity coefficient; where the activity intensity coefficient for hiking is generally 1.6-1.8; in high-altitude environments, oxygen consumption increases due to increased metabolic rate and respiratory compensation, and the compensatory oxygen consumption is generally 10%-20% of (basal metabolic oxygen demand + activity metabolic oxygen demand).

[0051] In one embodiment, the step of determining the total amount of oxygen that the oxygen concentrator can provide based on the oxygen concentrator parameters in step (S01) includes: firstly determining the battery endurance based on the battery parameters; and then determining the total amount of oxygen that the oxygen concentrator can provide based on the battery endurance and the set oxygen production capacity.

[0052] In this embodiment, the oxygen concentrator parameters include battery parameters and a set oxygen production capacity. The battery parameters include battery capacity and a power consumption curve corresponding to the set oxygen production capacity. The formula for calculating the total amount of oxygen the oxygen concentrator can provide includes:

[0053] O sup =Q set ×T bat ×60;

[0054] Among them, T bat The formula for calculating battery life is as follows:

[0055]

[0056] Among them, C bat P(Q) represents battery capacity, measured in Wh. set () is the power consumption curve corresponding to the set oxygen production capacity.

[0057] In one embodiment, the step of determining whether the initial power of the oxygen concentrator meets the first hiking goal based on the oxygen concentrator parameters and the hiker's total oxygen demand in S110 includes:

[0058] Determine whether the total amount of oxygen that the oxygen concentrator can provide is greater than or equal to the total amount of oxygen required by the hiker to complete the first hiking goal; if so, determine whether the battery life of the oxygen concentrator is greater than or equal to the planned total hiking time; if so, the initial power of the oxygen concentrator meets the first hiking goal.

[0059] In other words, in the example above, if Q sup ≥Q need And T bat ≥T total If the battery life meets the requirements, it indicates that the user can begin hiking. In actual use, this oxygen concentrator requires the battery to be fully charged to reduce the possibility of potential risks.

[0060] S120: Based on real-time monitoring of hikers' blood oxygen saturation and heart rate during the hike, the oxygen generator's oxygen production efficiency is dynamically adjusted, and the current runtime of the oxygen generator is determined according to the oxygen production efficiency.

[0061] In one embodiment, the steps of S120 described above include:

[0062] (S21) Determine the hiker's real-time blood oxygen saturation and real-time heart rate during the hike;

[0063] (S22) When the real-time blood oxygen saturation is lower than a preset first threshold and / or the real-time heart rate is higher than a preset second threshold, the oxygen generator’s set oxygen production capacity is adjusted; the first threshold may be, but is not limited to, set to blood oxygen saturation <90%;

[0064] The first threshold is a set minimum blood oxygen saturation threshold, and the second threshold is a set maximum heart rate threshold, such as, but not limited to, a heart rate > 120 beats / minute. When the real-time blood oxygen saturation is lower than the set minimum blood oxygen saturation threshold, and / or the real-time heart rate is higher than the set maximum heart rate threshold, the oxygen generator's set oxygen production is adjusted to provide sufficient oxygen.

[0065] (S23) Calculate the current operating time of the oxygen generator in real time based on the adjusted set oxygen production capacity.

[0066] In this embodiment, the step of calculating the current operating time of the oxygen concentrator in real time based on the adjusted set oxygen production capacity (S23) includes:

[0067] (S231) Calculate the remaining battery power of the oxygen concentrator based on the set oxygen production capacity; the formula for calculating the remaining battery power is:

[0068] Among them, C bat For battery capacity, Q set To set the oxygen production rate;

[0069] (S232) Calculate the current battery life based on the remaining battery power. The formula for calculating the current battery life is:

[0070] Wherein, P(Q) set (t) represents the current power consumption rate, and is related to the set oxygen production rate Q. set In this embodiment, the power consumption of the oxygen generator to maintain basic control functions is excluded. Since this power consumption is relatively low, it will not have a substantial impact on the result of the remaining power calculation.

[0071] S130: When the current battery life of the oxygen concentrator is insufficient to meet the second hiking goal, a timely return trip reminder will be issued.

[0072] In one embodiment, a reminder can also be set to be issued when the current battery life is less than 30 minutes.

[0073] The second hiking objective includes: the current estimated hiking time and the current remaining hiking distance.

[0074] In one embodiment, S130 above includes the following steps:

[0075] (S41) Determine the current estimated remaining hiking time based on the current remaining hiking distance and the current average hiking speed;

[0076] (S42) Determine whether the current battery life of the oxygen concentrator is less than the current estimated remaining hiking time. If so, issue a return trip reminder.

[0077] In this embodiment, if the battery life is insufficient to complete the entire hiking route, a return trip reminder will be issued promptly. The formula for calculating the remaining distance is: S rem =S total -S covered The formula for calculating the remaining time: T route =S rem / V avg ;where V avg Given the current average hiking speed, calculate the remaining time; if T rem <T route If so, a return trip reminder will be issued.

[0078] Since actual usage may differ from the aforementioned theoretical conditions, potentially leading to oxygen deficiency, this oxygen concentrator calculates the remaining time based on the user's actual situation, combines the user's heart rate, blood oxygen, and other parameters to calculate the actual oxygen consumption, and can promptly remind the user to return.

[0079] In the above embodiments, the setting and selection of some parameters can be obtained from empirical values ​​or from existing technologies.

[0080] The following is a detailed explanation of this embodiment using a specific example, as follows: the assumed hiking parameters and conditions include:

[0081] Hiking distance: 5km; Hiking time: 1.5h; Altitude range: 5000m-5500m.

[0082] Hiker physiological parameters:

[0083] Gender: Male; Age: 30; Weight: 70kg; Height: 175cm.

[0084] Oxygen concentrator parameters: O max =5L / min; C bat =150 watt-hours; P(Q) = 20QW; initial oxygen production capacity Q set = 1L / min.

[0085] The specific calculation process for step S110 and the relevant parameters used in this step is as follows:

[0086] First, calculate the oxygen requirement (Oxygen requirement = Basal metabolic oxygen demand + Activity metabolic oxygen demand + Compensatory oxygen consumption), that is:

[0087] (1) Calculate the basal metabolic rate (BMR): BMR = 10 x 70 + 6.25 x 175 - 5 x 30 + 5 = 1648.75 kcal / day;

[0088] (2) High-altitude correction BMR: At an altitude of 5000 meters, BMR increases by 25% (5% increase per 1000 meters): BMR at high altitude = 1648.75 × 1.25 = 2060.94 kcal / day;

[0089] (3) Calculate basal metabolic oxygen demand:

[0090]

[0091] (4) Active metabolic oxygen demand = 0.296 * 1.7 = 0.504 L / min;

[0092] (5) Oxygen demand (L / min): 0.296 + 0.504 + (0.296 + 0.504) * 10% = 0.88 L / min;

[0093] Then calculate the total oxygen demand (total oxygen demand O). need = Oxygen requirement * Planned total hiking time T total That is: 0.88L / min * 1.5 * 60 = 79.2L;

[0094] Next, we calculate the total amount of oxygen the oxygen concentrator can provide: Battery life:

[0095] Total oxygen supply of oxygen concentrator: O sup =1 × 7.5 × 60 = 450L;

[0096] Conclusion: Q sup ≥Q need The battery life meets the requirements.

[0097] The specific calculation process for step S120 is as follows:

[0098] Since a hiker's breathing rate and speed can be reflected in parameters such as blood oxygen saturation (SpO2) and heart rate (HR), this embodiment mainly focuses on calculating the core parameters. Adding too many reference variables would cause mutual interference between parameters, resulting in redundant and cumbersome algorithms. Therefore, in this embodiment, the inventors filtered out parameters with lower weights, retaining only blood oxygen saturation (SpO2) and heart rate (HR).

[0099] Assume the hiker's blood oxygen saturation (SpO2) and heart rate (HR) change per minute as follows (data is hypothetical):

[0100] Time (minutes) <![CDATA[SpO2(%)]]> Heart rate (HR) in bpm 0 95 80 1 94.8 81 2 94.5 82 … … … 30 90 90 60 85 100 90 80 110

[0101] The oxygen production rate is dynamically adjusted, and the adjustment rules are set as follows:

[0102] When SpO2 is less than 88%, the oxygen production rate increases by 1 L / min.

[0103] When the HR is greater than 100 bpm, the oxygen production also increases by 1 L / min (maximum not exceeding 5 L / min).

[0104] Based on blood oxygen and heart rate data every minute, the oxygen production needs to be dynamically adjusted every minute, and battery consumption needs to be calculated.

[0105] 1. The first 30 minutes:

[0106] Between 0 and 30 minutes, blood oxygen gradually decreased to 90%, and heart rate gradually increased to 90 bpm. During this period, neither blood oxygen nor heart rate reached the threshold, therefore the initial oxygen production rate Q was maintained. set＝ 1L / min, no adjustment required.

[0107] In the first 30 minutes, the battery consumption is: Power consumption = P(Q) set ) = 20 x 1 = 20W;

[0108] The amount of electricity consumed is: Electricity consumption = 20 x 30 / 60 = 10Wh;

[0109] Remaining battery capacity: C rem (30) = 150 - 10 = 140Wh;

[0110] 2. 30-60 minute phase: Starting from the 31st minute, as blood oxygen levels drop below 88% (reaching 85%) and heart rate rises to 100 bpm, oxygen production is adjusted. The oxygen production rate is increased from 1 L / min to 2 L / min.

[0111] Power consumption from 31 to 60 minutes: P(Q) set ) = 20 x 2 = 40W;

[0112] Battery consumption over 31-60 minutes: Power consumption = 40 x 30 / 60 = 20Wh;

[0113] Remaining battery capacity after 60 minutes: C rem (60) = 140 - 20 = 120Wh;

[0114] 3. The 60-minute to 90-minute stage:

[0115] Starting from the 61st minute, as blood oxygen levels further dropped to 80% and heart rate rose to 110 bpm, the oxygen production was adjusted back to 3 L / min.

[0116] Power consumption from 61 to 90 minutes: P(Q) set ) = 20 x 3 = 60W;

[0117] Battery consumption over 61-90 minutes: Power consumption = 60 x 30 / 60 = 30Wh;

[0118] Remaining battery capacity after 90 minutes: C rem (90) = 120 - 30 = 90Wh.

[0119] Calculate the remaining battery life and route time, i.e.:

[0120] Remaining battery life: Oxygen production maintained at 3L / min, power consumption P(Q) set =60W, current remaining battery capacity C rem =90Wh; Remaining battery life is:

[0121] Remaining route time:

[0122] Assuming there are 2 kilometers left to walk, and the hiking speed is 3 km / h, then the remaining time for the route is:

[0123] Ultimately, after adjusting the oxygen production in real time, the remaining battery life T rem = 1.5 hours, with a remaining hiking time of 0.67 hours, so the battery life is sufficient to support the completion of the remaining journey.

[0124] By monitoring human physiological indicators, oxygen production can be adjusted more precisely and timely responses can be made to changes in hikers' physiological parameters, thereby ensuring that oxygen supply matches battery endurance requirements during high-altitude hiking.

[0138] The oxygen concentrator's battery life control method, oxygen concentrator, oxygen concentrator system, oxygen concentrator battery life control system, oxygen generation system, storage medium, and UE device program products employ a dynamic evaluation and adjustment strategy for battery life. Furthermore, by combining oxygen concentrator parameters with the oxygen content and oxygen demand at corresponding altitudes, the battery life of the oxygen concentrator can be dynamically evaluated. This aligns with the battery life evaluation method, which calculates battery life based on battery capacity and device power consumption.

[0139] During the hike, the oxygen concentrator can adjust its oxygen production efficiency based on real-time data to optimize battery usage, demonstrating the technology's dynamic adjustment capabilities. It also monitors the hiker's blood oxygen saturation and heart rate, dynamically adjusting the concentrator's efficiency accordingly. If the battery life is insufficient for the entire hike, a timely return-to-base reminder is issued. This mechanism ensures the hiker's safety at high altitudes, showcasing the technology's real-time monitoring and early warning functions.
