[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] With the popularity of outdoor sports, more and more people choose to travel and explore in high-altitude areas. However, the oxygen is thin in high-altitude areas, which is likely to cause altitude sickness, and this phenomenon poses a serious threat to travelers, especially those engaged in outdoor sports. Portable oxygen generators can enable hikers to avoid the above situation as much as possible. However, in the actual use process, due to the inability to track the endurance and the actual situation of the human body during hiking in real time, the endurance of the oxygen generator cannot meet the requirements of hiking, thus causing potential risks during hiking.

[0035] Therefore, how to reduce or avoid the occurrence of personnel risks caused by insufficient battery life of the oxygen generator during hiking is a technical problem that urgently needs to be solved in this field. That is to say, the existing technology has technical problems of untimely and inaccurate monitoring of the dynamic battery life of the oxygen generator.

[0036] Based on this, the embodiments of the present invention provide an oxygen generator battery life control method, system and oxygen generator to solve the technical problems of untimely and inaccurate monitoring of the dynamic battery life of the oxygen generator in the existing technology.

[0037] To facilitate the understanding of this embodiment, first, a detailed introduction to an oxygen generator battery life control method disclosed in the embodiments of the present invention is given. The execution subject of this method is generally an intelligent device with certain computing capabilities. Such intelligent devices include, for example: terminal devices or oxygen generator devices with human-computer interaction functions. The terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a personal digital assistant (PDA), a handheld device, a wearable device, etc. In some possible implementation manners, the oxygen generator battery life control method can be implemented by a processor calling readable instructions stored in a memory.

[0038] See Figure 1 the flowchart of an oxygen generator battery life control method shown in the figure. This method mainly includes the following steps S110 to S140:

[0039] S110: Based on the oxygen generator parameters and the total oxygen demand of the hiker, determine that the initial power of the oxygen generator meets the first hiking goal;

[0040] Among them, the first hiking goal includes the planned total hiking time; in one embodiment, the first hiking goal further includes the planned hiking path and the corresponding altitude.

[0041] Before the above S110, this 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 demand of the first hiking goal according to the metabolic parameters of the hiker;

[0044] Among them, the metabolic parameters include: basal metabolic oxygen demand, activity metabolic oxygen demand, and compensatory oxygen consumption; in this embodiment, this step (S02) includes: first calculating the basal metabolic oxygen demand according to the basal metabolic rate of the hiker; then calculating the activity metabolic oxygen demand according to the basal metabolic oxygen demand and the activity intensity coefficient; then determining the compensatory oxygen consumption according to the sum of the basal metabolic oxygen demand and the activity metabolic oxygen demand; and finally determining the oxygen demand based on the basal metabolic oxygen demand, the activity metabolic oxygen demand, and the compensatory oxygen consumption.

[0045] (S03) Calculate the total oxygen demand of the hiker according to the oxygen demand and the planned total hiking time.

[0046] In one embodiment, the total oxygen demand is equal to the oxygen demand multiplied by the total hiking time (i.e., total oxygen demand O need = oxygen demand * planned total hiking time T total ), and the oxygen demand needs to comprehensively consider the basal metabolic oxygen demand, the activity metabolic oxygen demand, and the compensatory oxygen consumption (i.e., oxygen demand = basal metabolic oxygen demand + activity metabolic oxygen demand + compensatory oxygen consumption).

[0047] Among them, In the formula: BMR 高海拔 is the basal metabolic rate at the corresponding altitude, 24 is 24 hours a day, 60 is 60 minutes per hour, and the oxygen valence = 4.825 kcal / L (when the respiratory quotient is 0.8);

[0048] It should be noted that when determining the hiking route (the first hiking goal) of the hiker, the path shown on the map and the altitude can be used. Generally, for every 1000-meter increase in altitude, the basal metabolic rate (BMR) increases by about 5-10%, that is:

[0049] BMR 高海拔 = BMR 海平面 ×(1 + 0.05×h / 1000); where BMR 高海拔 represents the basal metabolic rate of a general hiking object at the corresponding altitude, and BMR 海平面 represents the basal metabolic rate of a general hiking object at sea level.

[0050] The activity metabolic oxygen demand = basal metabolic oxygen demand * activity intensity coefficient; among them, the activity intensity coefficient of hiking is generally 1.6-1.8; in a high-altitude environment, due to the increase in metabolic rate and respiratory compensation, the compensatory oxygen consumption is generally 10%-20% of (basal metabolic oxygen demand + activity metabolic oxygen demand).

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

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

[0053] O sup = Q set × T bat × 60;

[0054] where T bat is the battery endurance, and its calculation formula is:

[0055]

[0056] where C bat is the battery capacity, in Wh; P(Q set ) is the power consumption curve corresponding to the set oxygen production amount.

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

[0058] Judging whether the total amount of oxygen that the oxygen generator can provide is greater than or equal to the total oxygen demand of the hiker to complete the first hiking goal; if so, judging whether the battery endurance of the oxygen generator is greater than or equal to the planned total hiking time; if so, the initial power of the oxygen generator meets the first hiking goal.

[0059] That is to say, in the above example, if Q sup ≥ Q need , and T bat ≥ T total , it indicates that the battery endurance meets the requirements, prompting the user to start the hiking trip. The battery endurance meets the requirements. In actual use, this oxygen generator requires the battery to be fully charged to reduce the possibility of potential risks.

[0060] S120: Dynamically adjusting the oxygen production efficiency of the oxygen generator based on the blood oxygen saturation and heart rate of the hiker monitored in real time during the hiking process, and determining the current endurance time of the oxygen generator according to the oxygen production efficiency;

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

[0062] (S21) Determine the real-time blood oxygen saturation and real-time heart rate of the hiker during the hiking process;

[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, adjust the set oxygen production amount of the oxygen generator; the first threshold can be but is not limited to being set to a blood oxygen saturation < 90%;

[0064] Among them, the first threshold is the set lowest blood oxygen saturation threshold, and the second threshold is the set highest heart rate threshold. For example but not limited to being set to a heart rate > 120 beats per minute. When the real-time blood oxygen saturation is lower than the set lowest blood oxygen saturation threshold, and / or, the real-time heart rate is higher than the set highest heart rate threshold, adjust the set oxygen production amount of the oxygen generator to provide sufficient oxygen.

[0065] (S23) Calculate the current battery life of the oxygen generator in real time according to the adjusted set oxygen production amount.

[0066] In this embodiment, the step of calculating the current battery life of the oxygen generator in real time according to the adjusted set oxygen production amount in the above (S23) includes:

[0067] (S231) Calculate the remaining power of the oxygen generator battery according to the set oxygen production amount; the formula for calculating the remaining power is:

[0068] Among them, C bat is the battery capacity, and Q set is the set oxygen production amount;

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

[0070] Among them, P(Q set (t)) is the current power consumption rate and is related to the set oxygen production amount Q set ; in this embodiment, the power consumption for the oxygen generator to maintain the basic control function is excluded. Since this power consumption is relatively low, it will not have a substantial impact on the result of calculating the remaining power.

[0071] S130: When the current battery life of the oxygen generator cannot meet the second hiking goal, send a return reminder in a timely manner.

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

[0073] Among them, the second hiking goal includes: the current remaining estimated hiking time and the current remaining hiking mileage.

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

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

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

[0077] In this embodiment, when the battery life cannot meet the complete hiking route, a return reminder is sent in a timely manner. That is, the calculation formula for the remaining distance: S rem = S total - S covered ; The calculation formula for the remaining time: T route = S rem / V avg ; where V avg is the current average hiking speed to calculate the remaining time; if T rem < T route , then send a return reminder.

[0078] Since the actual usage situation may not match the aforementioned theoretical situation, it is easy to cause a potential risk of hypoxia; therefore, this oxygen generator calculates the remaining time based on the actual situation of the user, calculates the actual oxygen consumption in combination with parameters such as the user's heart rate and blood oxygen, and can timely remind the user to return.

[0079] In the above embodiment, the setting and selection of some parameters can be obtained according to empirical values or according to the prior art.

[0080] Next, the present embodiment will be described in detail with reference to a specific case. Specifically, the assumed hiking parameters and conditions are as follows:

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

[0082] Hiker's physiological parameters:

[0083] Gender: male; Age: 30 years old; Weight: 70 kg; Height: 175 cm.

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

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

[0086] First, calculate the oxygen demand (oxygen demand = basal metabolic oxygen demand + activity metabolic oxygen demand + compensatory oxygen consumption), that is:

[0087] (1) Calculate the basal metabolic rate BMR: BMR = 10x70 + 6.25x175 - 5x30 + 5 = 1648.75 kcal / day;

[0088] (2) Correct BMR for high altitude. 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 the basal metabolic oxygen demand:

[0090]

[0091] (4) Activity 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 demand * total planned hiking time T total ), that is: 0.88 L / min * 1.5 * 60 = 79.2 L;

[0094] Next, calculate the total oxygen that the oxygen generator can provide: Battery life:

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

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

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

[0098] Since the breathing rate and movement speed of the hiker can be reflected in the blood oxygen saturation (SpO2) and heart rate (HR) parameters, in this embodiment, the calculation is mainly carried out for the core parameters. After adding too many reference variables, it will cause mutual influence between the parameters, resulting in algorithm redundancy and complexity. Therefore, the inventor filtered the parameters with lower weights in this embodiment and only retained the blood oxygen saturation (SpO2) and heart rate (HR) parameters.

[0099] Assume that the changes in blood oxygen saturation (SpO2) and heart rate (HR) of a hiker per minute are as follows (the data are assumed):

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

[0101] Dynamically adjust the oxygen production amount, and set the adjustment rules as follows:

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

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

[0104] According to the blood oxygen and heart rate data per minute, it is necessary to dynamically adjust the oxygen production amount per minute and calculate the battery consumption.

[0105] 1. The first 30 - minute stage:

[0106] From 0 to 30 minutes, the blood oxygen gradually drops to 90%, and the heart rate gradually rises to 90 bpm. During this time period, neither the blood oxygen nor the heart rate reaches the threshold, so the initial oxygen production amount Q set＝ 1 L / min is maintained without adjustment.

[0107] In the first 30 minutes, the battery consumption is: Power consumption = P(Q set ) = 20x1 = 20 W;

[0108] The consumed electric quantity is: Electric quantity consumption = 20x30 / 60 = 10 Wh;

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

[0110] 2. The 30 - minute to 60 - minute stage: Starting from the 31st minute, as the blood oxygen drops below 88% (reaching 85%) and the heart rate rises to 100 bpm, the oxygen production amount adjustment is triggered. Increase the oxygen production amount from 1 L / min to 2 L / min.

[0111] Power consumption from 31 - 60 minutes: P(Q set ) = 20x2 = 40 W;

[0112] Battery consumption from 31 - 60 minutes: Electric quantity consumption = 40x30 / 60 = 20 Wh;

[0113] The remaining battery capacity at 60 minutes: C rem (60) = 140 - 20 = 120 Wh;

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

[0115] Starting from the 61st minute, as the blood oxygen further drops to 80%, the heart rate rises to 110 bpm, so the oxygen production is adjusted to 3 L / min again.

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

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

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

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

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

[0121] Remaining route time:

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

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

[0124] By monitoring the human physiological indicators, the oxygen production can be adjusted more precisely and the changes in the physiological parameters of the hiker can be responded to in a timely manner, so as to ensure that the oxygen supply in high-altitude hiking matches the battery life requirements.

This mechanism ensures the safety of the hiker in a high-altitude environment, demonstrating the real-time monitoring and early warning functions of the technology.
