Description

Technical Field

[0001] The present application relates to the field of smart home technology, and more specifically, to an oxygen concentration detection system and method, a storage medium, and an electronic device. Background Art

[0002] In the current field of home oxygen concentrators, accurate testing of oxygen concentration is key to ensuring product performance and user safety. Traditional oxygen concentration testing methods usually rely on a single sensor (e.g. Figure 1 The oxygen concentration tester shown) is connected directly to an oxygen concentrator (e.g. Figure 2 The oxygen concentrator (as shown) is connected to the outlet pipe of the oxygen concentrator and the real-time oxygen concentration value is read on the display. However, this method has significant limitations. On the one hand, in the early stage of operation of the oxygen concentrator, the dynamic balance within the system has not yet been established, and the oxygen concentration at the outlet may fluctuate, resulting in unstable sensor readings. This volatility not only complicates the acquisition of test results, but also makes it more difficult to determine whether the oxygen concentration meets the regulations when it approaches the lower limit of the qualified standard, increasing the uncertainty of the test. On the other hand, the determination of data stability often relies on the experience and subjective judgment of the operator, and is easily affected by personal factors such as distraction and fatigue, which may lead to misjudgment of test results and affect the consistency and accuracy of product quality control.

[0003] With regard to the problem in related technologies that the concentration of oxygen generated by an oxygen concentrator cannot be accurately determined, no effective solution has been proposed so far.

[0033] In order to solve the above problems, an oxygen concentration detection system is provided in this embodiment. Figure 4 1 is a block diagram of an oxygen concentration detection system according to an embodiment of the present invention, the oxygen concentration detection system comprising:

[0034] Oxygen measuring chamber 20, first oxygen concentration detection sensor 30, second oxygen concentration detection sensor 40, processor 50;

[0035] The bottom air inlet of the oxygen measuring chamber is connected to the air outlet of the oxygen concentrator, the first oxygen concentration detection sensor and the second oxygen concentration detection sensor are both located inside the oxygen measuring chamber, the distance between the first oxygen concentration detection sensor and the bottom air inlet of the oxygen measuring chamber is less than a first preset threshold, and the distance between the second oxygen concentration detection sensor and the top air outlet of the oxygen measuring chamber is less than a second preset threshold;

[0036] The processor is connected to the first oxygen concentration detection sensor and the second oxygen concentration detection sensor, and is used to determine the concentration of oxygen generated by the oxygen concentrator based on the detection data of the first oxygen concentration detection sensor and the detection data of the second oxygen concentration detection sensor.

[0037] It should be noted that the processor is connected to the first oxygen concentration detection sensor and the second oxygen concentration detection sensor via a signal transmission line.

[0038] The above system ensures the stability and accuracy of oxygen concentration data through dual detection by a first oxygen concentration detection sensor at the bottom of the oxygen chamber and a second oxygen concentration detection sensor at the top, combined with processor analysis, solving the problem of being unable to accurately determine the concentration of oxygen produced by the oxygen concentrator under the traditional single sensor method.

[0039] It should be noted that the above system is able to more comprehensively monitor changes in oxygen concentration by setting two oxygen concentration detection sensors in the oxygen measuring chamber, respectively located near the inlet and outlet of the oxygen flow. This design not only increases the redundancy of detection and improves the reliability of the system, but also can detect the performance of the oxygen concentrator and the concentration changes during the oxygen transmission process by comparing the data of the two sensors, thereby ensuring accurate measurement of the oxygen concentration. For example, if the oxygen concentration of the oxygen concentrator is unstable during operation, the comparison of the data from the two sensors can help identify the problem, whether it is a problem with the oxygen concentrator itself or a loss during the transmission process. In this way, the present technical solution solves the problems of limited detection accuracy and insufficient fault detection capability of a single sensor, and achieves more accurate and reliable oxygen concentration detection.

[0040] In an exemplary embodiment, the processor is configured to determine the concentration of oxygen generated by the oxygen concentrator based on the detection data of the first oxygen concentration detection sensor and the detection data of the second oxygen concentration detection sensor in the following manner: drawing a first curve based on the detection data of the first oxygen concentration detection sensor, and drawing a second curve based on the detection data of the second oxygen concentration detection sensor, wherein the first curve and the second curve are both used to represent the correspondence between time and oxygen concentration; and determining the concentration of oxygen generated by the oxygen concentrator based on the first curve and the second curve.

[0041] It's important to note that by plotting two curves, the processor can intuitively analyze the changing trends of oxygen concentration over time, helping to identify fluctuations and potential anomalies. For example, if the two curves exhibit similar fluctuation trends within a target time period, with a high degree of overlap, the oxygen concentration can be considered stable during that period, thus determining the average oxygen concentration. This analytical method, combining time series analysis with data comparison, more accurately reflects the true state of oxygen concentration and addresses the problem of traditional point measurement methods being unable to capture oxygen concentration fluctuations.

[0042] Optionally, the first curve and the second curve are as follows: Figure 5 and Figure 6 As shown, in which Figure 5 and Figure 6 In the figure, the upper curve is the first curve and the lower curve is the second curve.

[0043] In an exemplary embodiment, the processor is configured to determine the concentration of oxygen generated by the oxygen concentrator based on the first curve and the second curve in the following manner: when the degree of overlap between the sub-curve corresponding to the first curve and the sub-curve corresponding to the second curve in a target time period is greater than a third preset threshold, determine the concentration of oxygen generated by the oxygen concentrator based on detection data of the first oxygen concentration detection sensor in the target time period and detection data of the second oxygen concentration detection sensor in the target time period.

[0044] It should be noted that the time interval between the start time of the target time period and the start time of the oxygen concentrator is greater than the preset time interval, that is, the target time period is not the period immediately after the oxygen concentrator is started.

[0045] It should be noted that using the curve overlap as a basis for judgment can ensure accurate measurement when the oxygen concentration is stable. For example, when the oxygen concentrator is operating stably and oxygen is evenly distributed in the oxygen measurement chamber, the detection data from the two sensors should show a high degree of consistency. At this time, by comparing the overlap of the two curves, measurement errors caused by uneven airflow distribution or sensor failure can be effectively identified and eliminated. This technical solution solves the problem of accurate oxygen concentration detection in complex airflow environments and achieves more accurate concentration measurement.

[0046] In an exemplary embodiment, the processor is configured to determine the concentration of oxygen generated by the oxygen concentrator based on detection data of the first oxygen concentration detection sensor and detection data of the second oxygen concentration detection sensor during the target time period in the following manner: calculating an average value of the detection data of the first oxygen concentration detection sensor during the target time period to obtain a first average value; and calculating an average value of the detection data of the second oxygen concentration detection sensor during the target time period to obtain a second average value; and determining the average value of the first average value and the second average value as the concentration of oxygen generated by the oxygen concentrator.

[0047] It's important to note that calculating the average concentration effectively eliminates the impact of transient fluctuations on oxygen concentration measurements, providing more stable and reliable oxygen concentration data. For example, when oxygen concentration in an oxygen concentrator fluctuates significantly over a short period of time, calculating the average of the two sensor data can filter out these transient fluctuations and produce an average value closer to the true concentration. This technical solution addresses the issue of transient fluctuations in oxygen concentration measurement and achieves more stable concentration measurements.

[0048] In an exemplary embodiment, the processor is further used to: determine whether the concentration value detected by the first oxygen concentration detection sensor at a target time is greater than the concentration value detected by the second oxygen concentration detection sensor, wherein the target time is a time before the target time period; if the concentration value detected by the first oxygen concentration detection sensor at the target time is greater than the concentration value detected by the second oxygen concentration detection sensor, determine that the first oxygen concentration detection sensor and the second oxygen concentration detection sensor are not faulty.

[0049] It should be noted that by comparing the detection values ​​of the two sensors at the target time, sensor failure status can be effectively detected. For example, at the beginning of the oxygen concentrator's operation, the oxygen concentration gradually increases from low to high. If the concentration value of the first sensor (near the oxygen inlet) is always higher than the concentration value of the second sensor (near the oxygen outlet), it can be assumed that both sensors are working properly and there is no fault. This fault detection mechanism combines the natural change trend of oxygen concentration to accurately determine the operating status of the sensor and avoid measurement errors caused by sensor failure.

[0050] In an exemplary embodiment, the first oxygen concentration detection sensor and the second oxygen concentration detection sensor both have a temperature compensation function for adjusting an internal oxygen concentration detection algorithm according to the ambient temperature.

[0051] It's important to note that the temperature compensation function ensures that the oxygen concentration sensor provides accurate results in varying temperature environments. For example, chemical reactions or the performance of electronic components within the oxygen concentration sensor can be affected by temperature fluctuations. The built-in temperature compensation algorithm allows the sensor to adjust detection parameters in real time to offset the effects of temperature on test results. This technical solution addresses the impact of temperature fluctuations on oxygen concentration accuracy and enables concentration measurement in a wider range of environments.

[0052] In an exemplary embodiment, an airflow guiding structure is provided inside the oxygen measuring chamber, and the airflow guiding structure is used to guide the oxygen entering from the bottom air inlet to reach the positions of the first oxygen concentration detection sensor and the second oxygen concentration detection sensor.

[0053] It's important to note that the design of the airflow guidance structure optimizes the distribution of oxygen within the oxygen measurement chamber, ensuring that both sensors receive consistent oxygen concentrations, thereby improving detection accuracy. For example, by installing guide plates or airflow channels within the chamber, oxygen can be effectively directed evenly to both sensors, avoiding detection errors caused by localized uneven airflow. This technical solution solves the airflow distribution issue in oxygen concentration detection, achieving more uniform and accurate concentration measurements.

[0054] It should be noted that, in this embodiment, an oxygen concentration detection method is provided, which is applied to an oxygen measuring chamber, wherein a first oxygen concentration detection sensor and a second oxygen concentration detection sensor are both located inside the oxygen measuring chamber, and a bottom air inlet of the oxygen measuring chamber is connected to an air outlet of an oxygen concentrator. The distance between the first oxygen concentration detection sensor and the bottom air inlet of the oxygen measuring chamber is less than a first preset threshold, and the distance between the second oxygen concentration detection sensor and the top air outlet of the oxygen measuring chamber is less than a second preset threshold. Figure 7 This is a flow chart of an oxygen concentration detection method according to an embodiment of the present invention, which includes the following steps S702-S704:

[0055] Step S702: Acquire detection data of the first oxygen concentration detection sensor and detection data of the second oxygen concentration detection sensor;

[0056] Step S704: Determine the concentration of oxygen generated by the oxygen concentrator according to the detection data of the first oxygen concentration detection sensor and the detection data of the second oxygen concentration detection sensor.

[0057] The above steps ensure the stability and accuracy of oxygen concentration data through dual detection by the first oxygen concentration detection sensor at the bottom of the oxygen chamber and the second oxygen concentration detection sensor at the top, combined with processor analysis, and solve the problem of being unable to accurately determine the concentration of oxygen generated by the oxygen concentrator under the traditional single sensor method.

[0058] It should be noted that, for the description of the features in the embodiment corresponding to the oxygen concentration detection method, reference can be made to the relevant description of the embodiment corresponding to the oxygen concentration detection system, which will not be repeated here.

[0059] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all the embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present invention. Specifically:

[0060] The related technology measurement is just a simple sensor + data display, without the function of analyzing and judging the stability of data. In addition, the readings are volatile, and the stability of the data is difficult to read. This application can automatically obtain two data through two sensors and a computer program curve, obtain a stable value, and automatically calculate the average value, solving the reading difficulties and the difficulty of subjective data fluctuations. Specifically, optionally, as Figure 8 As shown, the oxygen concentration tester is mainly composed of an oxygen measuring chamber, a sensor, a computer and data processing software.

[0061] 1) Oxygen sensors M1 and M2 use sensors of the same specifications.

[0062] 2) Oxygen from the oxygen generator enters the oxygen measurement chamber through the conduit. The oxygen measurement chamber inlet is located at the bottom, and the weight of the oxygen is greater than that of the air, which will gradually expel the air from the oxygen measurement chamber, and finally only oxygen is left.

[0063] 3) The oxygen sensor M1 at the inlet first tests the oxygen, and gradually increases the oxygen concentration with time. The M2 sensor contacts the oxygen from the oxygen generator, and the test concentration also gradually increases with time.

[0064] 4) When the air in the oxygen measurement chamber is gradually expelled, the value curves of the M1 and M2 oxygen sensors gradually merge. When M1 and M2 are completely coincident, the air in the oxygen chamber has been completely expelled at this time.

[0065] 5) The oxygen concentration test curve is shown in Figure 5 and Figure 6 When the M1 and M2 curves are completely coincident, and are stable for 1-10 minutes (the time can be set by software), at this time the data in this segment is selected to automatically calculate the average value. The data tested at this time is the oxygen concentration test data.
