Description

Technical Field

[0001] This application relates to the field of detection, and in particular to a method for detecting gas concentration, electronic equipment, and computer-readable storage medium. Background Technology

[0002] Refrigerants such as R22 and R410A, widely used in existing household appliances like air conditioners and dehumidifiers, damage the ozone layer and contribute significantly to the greenhouse effect, thus requiring replacement. In contrast, naturally occurring compounds like R290 (propane) and R32 are environmentally friendly refrigerants that neither damage the ozone layer nor contribute to global warming. Therefore, R290 and R32 can replace R22 and R410A as refrigerants in household appliances such as air conditioners and dehumidifiers. However, R290 and R32 are flammable and explosive refrigerants, placing high safety requirements on systems using them. Currently, air conditioners using flammable and explosive refrigerants like R290 and R32 are typically equipped with refrigerant leak detection devices. When a leak is detected, the system automatically shuts down and vents the gas to prevent the leaked refrigerant from being ignited by electrical sparks from the air conditioner. Currently, there are three common types of devices for detecting refrigerant leaks: semiconductor, catalytic combustion, and infrared absorption. Among them, semiconductor sensors are widely used in the civilian sector due to their low cost and long lifespan. However, because of the broad spectrum of this type of sensor, it responds to both oxidizing and reducing gases. Therefore, other gases that may be present indoors, such as ethanol, acetic acid, methane, carbon monoxide, and formaldehyde, can trigger the semiconductor sensor's response, interfering with the sensor's accurate output of refrigerant information and leading to false alarms. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0015] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] Before introducing the technical solution of this application, a brief introduction to the relevant technical solutions will be given.

[0017] To address the issue of interfering gases affecting the sensor's output for the target gas, one approach is to add a filter to the sensor. This filter adsorbs easily adsorbed interfering gases such as ethanol, acetone, isopropanol, and methanol, preventing them from affecting the sensor's concentration determination. Another approach is to use gas-sensitive materials to significantly reduce the sensor's sensitivity to interfering gases, thereby minimizing their impact on the sensor's output concentration. Finally, a combination of gas-sensitive materials can be used to detect the concentration of different gases and differentiate between them.

[0018] In this application, the embodiments described below are applied to a detection system. This detection system includes two gas sensors, and the type of gas is determined based on the different response characteristics of the two gas sensors to the gas, helping to distinguish between target gas and interfering gas in the detection environment.

[0019] Reference Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the gas concentration detection method of this application. It includes the following steps:

[0020] S11: Obtain the first concentration detected by the first detection device in the environment to be tested, wherein the response rate of the first detection device to the target gas is higher than the response rate to the interfering gas.

[0021] The detection device used to obtain the first concentration has a higher response rate to the target gas than to the interfering gas. This indicates that the first detection device is more sensitive to the target gas than to the interfering gas, and its detection of the target gas is more accurate and better able to detect it. The response rate is the ratio between the sensor output and the corresponding input. For example, if there is a target gas with a concentration of 50 and an interfering gas with a concentration of 50 in the environment, and the detection device outputs a concentration of 60, including the target gas with a concentration of 50 and the interfering gas with a concentration of 10, then the response rate of the detection device to the target gas is 50 divided by 50, which is 100%, and the response rate of the detection device to the interfering gas is 10 divided by 50, which is 20%. In this environment, the response rate of the detection device to the target gas is higher than that to the interfering gas. The units of the concentration values ​​are the same.

[0022] S12: Obtain the second concentration detected by the second detection device in the environment to be tested, wherein the response rate of the second detection device to the interfering gas is higher than the response rate to the target gas.

[0023] The detection device used to obtain the second concentration has a higher response rate to interfering gases than to the target gas. This indicates that the first detection device is more sensitive to interfering gases than to the target gas, and its detection of interfering gases is more accurate and better able to detect them. The response rate is the ratio between the sensor output and the corresponding input. For example, if the environment contains a target gas with a concentration of 50 and an interfering gas with a concentration of 50, and the detection device outputs a concentration of 60 (including the interfering gas with a concentration of 50 and the target gas with a concentration of 10), then the response rate of the detection device to the interfering gas is 50 divided by 50, which is 100%, and the response rate to the target gas is 10 divided by 50, which is 20%. In this environment, the response rate of the detection device to the interfering gas is higher than that to the target gas. The units of the concentration values ​​are the same.

[0024] S13: Calculate the concentration of the target gas based on the first concentration and the second concentration.

[0025] After obtaining the first and second concentrations, the first and second concentrations are calculated, the target gas is determined according to the response rate of the detection device, and the concentration of the target gas is calculated.

[0026] In this embodiment, by setting the first detection device and the second detection device to meet their respective response rate requirements, the first detection device has a higher response rate to the target gas than to the interfering gas, and the second detection device has a higher response rate to the interfering gas than to the target gas. Then, the first concentration detected by the first detection device and the second concentration detected by the second detection device in the environment under test are obtained. The target gas and the interfering gas in the environment under test are distinguished and judged by the detection concentrations of the detection devices with different gas response rates.

[0027] In one embodiment, before obtaining the first concentration detected by the first detection device in the environment to be tested, the first detection device is set at a first operating temperature and the second detection device is set at a second operating temperature, wherein the first operating temperature is different from the second operating temperature, so that the first detection device and the second detection device meet the corresponding response rate requirements.

[0028] To ensure that the detection devices meet their respective response rate requirements, a corresponding operating temperature is set for them so that at the corresponding temperature, the detection device is more sensitive to the target gas than to the interfering gas, or more sensitive to the interfering gas than to the target gas.

[0029] In one embodiment, the response rate requirement for the first detection device includes a ratio of the response rate of the first detection device to the target gas to the response rate to the interfering gas of not less than 2, and the response rate requirement for the second detection device includes a ratio of the response rate of the second detection device to the interfering gas to the response rate to the target gas of not less than 2. A larger response rate ratio indicates a greater difference in sensitivity to the target gas and the interfering gas, thus ensuring the accuracy of the gas concentration determination by the detection device after detection.

[0030] During testing, the operating temperature of the first detection device is typically adjusted. When the ratio of the response rate of the first detection device to the target gas to the response rate to the interfering gas reaches its maximum, this temperature indicates that it is the optimal detection temperature for the target gas, and this optimal detection temperature is used as the first operating temperature of the first detection device. Similarly, the operating temperature of the second detection device is adjusted. When the ratio of the response rate of the second detection device to the interfering gas to the response rate to the target gas reaches its maximum, this temperature indicates that it is the optimal detection temperature for the interfering gas, and this optimal detection temperature is used as the second operating temperature of the second detection device.

[0031] In one embodiment, the difference between the first operating temperature and the second operating temperature is not less than 40 degrees Celsius. The greater the difference between the operating temperatures of the detection device, the greater the difference in its sensitivity to the target gas and the interfering gas, and the more accurate the detection device is in determining the gas concentration after detection.

[0032] Reference Figure 2 , Figure 2 This is a schematic flowchart of the second embodiment of the gas concentration detection method of this application. This method is a further extension of step S13. It includes the following steps:

[0033] S21: Calculate the ratio of the first concentration to the second concentration.

[0034] S22: In response to a ratio less than or equal to a first threshold, the concentration of the target gas is set to zero; in response to a ratio greater than or equal to a second threshold, the first concentration is used as the concentration of the target gas; in response to a ratio between the first threshold and the second threshold, the first concentration and the second concentration are weighted based on the first threshold and the second threshold to obtain the concentration of the target gas.

[0035] The system acquires a first concentration detected by a first detection device and a second concentration detected by a second detection device. The ratio of the first concentration to the second concentration is compared with a preset threshold to determine the concentration of the target gas. The preset threshold includes a first threshold and a second threshold. When the ratio is less than or equal to the first threshold, it indicates the presence of only interfering gas. When the ratio is greater than or equal to the second threshold, it indicates the presence of only the target gas. When the ratio is between the first and second thresholds, it indicates the presence of both the target gas and the interfering gas.

[0036] The threshold can be determined and set using the methods described below.

[0037] In one embodiment, before calculating the concentration of the target gas based on the first concentration and the second concentration, a first response rate corresponding to the first concentration is determined based on the first response rate curve corresponding to the first detection device, and the first response rate is used as a first threshold, wherein the first response rate curve is used to characterize the ratio between the detection concentration of the first detection device and the concentration of the interfering gas when only the interfering gas is present; a second response rate corresponding to the second concentration is determined based on the second response rate curve corresponding to the second detection device, and the reciprocal of the second response rate is used as a second threshold, wherein the second response rate curve is used to characterize the ratio between the detection concentration of the second detection device and the concentration of the target gas when only the target gas is present.

[0038] When the first detection device operates at a first operating temperature, it is placed in an environment containing only interfering gases, and its detection outputs at different concentrations of interfering gases are obtained. The ratio of the output concentration to the corresponding input concentration of the interfering gas indicates the percentage of interfering gas in the output of the first detection device at the first operating temperature that is identified as the target gas; this is equivalent to the identification conversion rate of the interfering gas as the target gas at the first operating temperature. This ratio is also used as the first response rate obtained by comparing the output of the first detection device with the corresponding input in this environment. When the second detection device operates at a second operating temperature, it is placed in an environment containing only the target gas, and its detection outputs at different concentrations of the target gas are obtained. The ratio of the output concentration to the corresponding input concentration of the target gas indicates the percentage of the target gas in the output of the second detection device at the second operating concentration that is identified as the interfering gas; this is equivalent to the identification conversion rate of the target gas as the target gas at the second operating temperature. This ratio is also used as the second response rate obtained by comparing the output of the second detection device with the corresponding input in this environment.

[0039] Furthermore, the first response rate is set as the first threshold, and the reciprocal of the second response rate is set as the second threshold. The first threshold and the second threshold can serve as the boundary for determining the target gas and the interfering gas.

[0040] In one embodiment, when the ratio of the first concentration to the second concentration is between a first threshold and a second threshold, it indicates the presence of both the target gas and interfering gases. In this case, a weighted average is needed to obtain the concentration of the target gas. The weighted average can be achieved using the following formula:

[0041] C=C1-C2[(M2-C1 / C2) / (M2-M1)]*k1,

[0042] Where C is the concentration of the target gas, C1 is the first concentration, C2 is the second concentration, M1 is the first threshold, M2 is the second threshold, and k1 is the first response rate corresponding to the first detection device.

[0043] The concentration of interfering gases can also be calculated in a similar way, or by subtracting the concentration of the target gas from the total concentration of the target interfering gases.

[0044] In this embodiment, the application configures the first and second detection devices to meet their respective response rate requirements. The first detection device has a higher response rate to the target gas than to the interfering gas, and the second detection device has a higher response rate to the interfering gas than to the target gas. Then, the first concentration detected by the first detection device and the second concentration detected by the second detection device in the test environment are obtained, and the ratio of the first concentration to the second concentration is compared with a preset threshold. The preset threshold is determined based on the response rates of the detection devices to the target gas or interfering gas under different response characteristics. Therefore, the target gas and interfering gas can be distinguished based on the comparison result of the ratio of the first concentration to the second concentration and the preset threshold. When both the target gas and interfering gas are present in the detection environment, the concentration of the target gas can also be determined based on the preset threshold and the response rates of the detection devices to the target gas or interfering gas under different response characteristics.

[0045] The following specific embodiment will be used to illustrate the technical solution of this application in more detail.

[0046] First, perform step one: calibrate the sensor response rate.

[0047] Adjust sensor S1 to the optimal operating temperature of the target gas. In an environment containing only interfering gas, when the concentration of the interfering gas is C, sensor S1 outputs a concentration of C1. The contribution rate of the interfering gas to the target gas, i.e., the recognition conversion rate of the interfering gas being identified as the target gas, is k1 = C1 / C. Contribution rate curves at different concentrations are then obtained. Similarly, adjust sensor S2 to the optimal operating temperature of the interfering gas. In an environment containing only the target gas, when the concentration of the target gas is C, sensor S2 outputs a concentration of C2. The contribution rate of the target gas to the interfering gas, i.e., the recognition conversion rate of the target gas being identified as the target gas, is k2 = C2 / C. Contribution rate curves at different concentrations are then obtained.

[0048] k1 represents the first response rate corresponding to the first detection device, and k2 represents the second response rate corresponding to the second detection device.

[0049] After calibration is completed, step two can be carried out to detect the gas to be tested.

[0050] Adjust sensor S1 to the optimal operating temperature of the target gas and maintain it, and adjust sensor S2 to the optimal operating temperature of the interfering gas and maintain it.

[0051] A first threshold is set as k1, representing the first response rate of the first detection device. A second threshold is set as 1 / k2, representing the reciprocal of the second response rate of the second detection device. The target gas is then identified based on these thresholds.

[0052] When the ratio of the output concentration CT1 of sensor S1 to the output concentration CT2 of sensor S2 satisfies condition A: CT1 / CT2 >= 1 / k2, it is determined that there is no interfering gas in the environment to be detected.

[0053] When the ratio of the output concentration CT1 of sensor S1 to the output concentration CT2 of sensor S2 satisfies condition B: CT1 / CT2 <= k1, it is determined that there is only interfering gas in the environment to be detected.

[0054] When the ratio of the output concentration CT1 of sensor S1 to the output concentration CT2 of sensor S2 satisfies condition C: k1 < CT1 / CT2 < 1 / k2, it is determined that both the target gas and the interfering gas exist in the environment to be detected.

[0055] After completing the detection of the gas to be measured, step three can be implemented to calculate and obtain the concentration of the target gas.

[0056] When condition A is satisfied, there is no interfering gas in the environment to be detected, and the concentration of the target gas is CT1, which is equal to the detection output concentration of the first detection device.

[0057] When condition B is satisfied, there is only interfering gas in the environment to be detected, and the concentration of the target gas is 0.

[0058] When condition C is satisfied, both the target gas and the interfering gas exist in the environment to be detected, and the concentration of the target gas is calculated to be approximately CT1 - [CT2(1 / k2 - CT1 / CT2) / (1 / k2 - k1)] * k1.

[0059] When the technical solution described in this application is used, there is no need to install a filtering device for the sensor. Only relying on the response characteristics of the sensor itself, different sensors with different response characteristics are used to detect the environment to be detected, so as to identify and determine the target gas and / or interfering gas according to their respective output concentrations. Since the different response characteristics of the sensor to the gas are utilized, the detection device used in this application does not need to rely on specific sensitive materials and can be applicable to various scenarios with interfering gases. When the sensor works and detects at the optimal detection temperature of the target gas or the interfering gas, the accuracy of the judged gas concentration is higher.

[0060] In this application, when the response characteristics of the detection device to multiple interfering gases are similar, they can be classified into one type of interfering gas for calculation. For example, when a detection device detects multiple interfering gases and finds that their corresponding optimal detection temperatures are very close, they can be classified into the same type of interfering gas, and then the overall concentration determination and calculation of this type of interfering gas are carried out. <{

[0061] Such as Figure 3 shown, Figure 3 is a schematic structural diagram of an embodiment of the electronic device of this application.

[0062] The electronic device includes a processor 110 and a memory 120.

[0063] Processor 110 controls the operation of electronic devices. Processor 110 may also be referred to as a CPU (Central Processing Unit). Processor 110 may be an integrated circuit chip with signal sequence processing capabilities. Processor 110 may also be a general-purpose processor, a digital signal sequence processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. A general-purpose processor may be a microprocessor or any conventional processor.

[0064] The memory 120 stores the instructions and program data required for the processor 110 to operate.

[0065] The processor 110 is used to execute instructions to implement the methods provided by any embodiment and possible combination of the gas concentration detection methods described above in this application.

[0066] like Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of an embodiment of the computer-readable storage medium of this application.

[0067] One embodiment of the readable storage medium of this application includes a memory 210 that stores program data that, when executed, implements the method provided by any embodiment and possible combination of the gas concentration detection method of this application.

[0068] The memory 210 may include a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk, or other media that can store program instructions. Alternatively, it may be a server that stores the program instructions, which can send the stored program instructions to other devices for execution or execute the stored program instructions itself.

[0069] In summary, this application sets the first and second detection devices to meet their respective response rate requirements, such that the first detection device has a higher response rate to the target gas than to the interfering gas, and the second detection device has a higher response rate to the interfering gas than to the target gas. Then, it obtains the first concentration detected by the first detection device and the second concentration detected by the second detection device in the environment under test. The target gas and interfering gas in the environment under test are distinguished and judged by the detection concentrations of the detection devices with different gas response rates.

[0070] Furthermore, this application eliminates the need for a filter in the detection device; it only requires setting the operating temperature to achieve different gas response characteristics. Because it utilizes the different gas response characteristics of the sensors, it eliminates the need for sensitive materials to distinguish between individual gases. During gas concentration calculation, the preset threshold is determined based on the response rate of the detection device to the target gas or interfering gas under different response characteristics. This allows for the differentiation of the target gas and interfering gas based on the comparison between the ratio of the first concentration to the second concentration and the preset threshold. Even when both the target gas and interfering gas are present in the detection environment, the concentration of the target gas can be determined based on the preset threshold and the response rate of the detection device to the target gas or interfering gas under different response characteristics. The calculation steps are simple and highly accurate.
