[0004] However, the above method of determining the volatile organic compound contribution value of each interior part or material to the air inside the vehicle only considers the performance of different interiors in emitting VOCs individually, and does not consider the actual situation that dozens of interiors in the entire vehicle emit VOCs at the same time, resulting in an extremely complex VOC diffusion concentration gradient.

[0024] In order to solve the above problems, the embodiments of the present disclosure provide a method for detecting and processing volatile organic compounds, which will be introduced below in conjunction with specific embodiments.

[0025] Figure 1 The present invention provides a flow chart of a method for detecting and processing volatile organic compounds, which can be performed by a device for detecting and processing volatile organic compounds, wherein the device can be implemented by software and / or hardware and can generally be integrated into an electronic device. Figure 1 As shown, the method includes:

[0026] Step 101 : obtaining a first organic matter volatilization concentration of a sampling container after a preset time period, wherein the sampling container contains a target interior and a preset organic matter volatilization device.

[0027] The sampling container may be any container such as a sampling bag or an environmental chamber, wherein the preset time period may be determined according to the preset VOC detection standard. For example, if the volatile organic compound contribution value specified in the VOC detection standard is a contribution value of 16 hours, then the corresponding preset time period is 16 hours; for another example, if the volatile organic compound contribution value specified in the VOC detection standard is a contribution value of 24 hours, then the corresponding preset time period is 24 hours, etc. In addition, if the preset VOC detection standard also specifies other environmental parameters, the environment is also adjusted in the sampling container according to the corresponding environmental parameters. For example, if the preset VOC detection standard also specifies that the detection temperature is 25 degrees, then when detecting the first organic volatile concentration, the temperature in the sampling container needs to be maintained at 25 degrees, etc.

[0028] It should be noted that the sampling container contains a target interior and a preset organic matter volatilization device, and the target interior can be any object in the vehicle containing organic materials, including but not limited to vehicle seats, carpets, etc. In one embodiment of the present disclosure, a first organic matter volatilization concentration of the sampling container after a preset time period is obtained, wherein the first organic matter volatilization concentration can be obtained by detecting the air in the sampling container through a VOC detector or the like.

[0029] Step 102 : obtaining a second organic matter volatilization concentration corresponding to a preset organic matter volatilization device and a preset time.

[0030] In this embodiment, the second organic volatilization concentration is predetermined. In one embodiment of the present disclosure, the correspondence between different time periods and the organic volatilization concentration of a preset organic volatilization device can be pre-stored, and the second organic volatilization concentration can be obtained based on the correspondence query.

[0031] Step 103 , obtaining a correspondence between the vehicle where the target interior is located and the preset volatile matter concentration of the preset organic matter volatilization device.

[0032] It should be emphasized that the preset organic volatilization device of the embodiment of the present disclosure has a fixed corresponding relationship with the organic volatilization concentration in the vehicle where the target interior is located, and the corresponding relationship is a preset volatile concentration corresponding relationship. For example, the corresponding relationship between the vehicle where the target interior is located and the preset volatile concentration of the preset organic volatilization device is a corresponding ratio relationship, for example, the ratio is 1.5, etc. Since the preset organic volatilization device and the organic volatilization concentration in the vehicle where the target interior is located have a preset volatile concentration corresponding relationship, the second organic volatilization concentration based on the preset organic volatilization device can indirectly simulate the VOC concentration environment under the joint action of all interiors in the vehicle.

[0033] Step 104 , calculating and processing the second organic matter volatile concentration according to the preset volatile matter concentration correspondence relationship to obtain a reference organic matter volatile concentration.

[0034] In one embodiment of the present disclosure, the second organic volatile concentration is calculated and processed according to the preset volatile concentration correspondence relationship to determine the reference organic volatile concentration, wherein the reference organic volatile concentration is obviously the VOC environmental concentration of the vehicle where the target interior is located. In some possible examples, if the preset volatile concentration correspondence relationship is a ratio relationship, the product value of the preset volatile concentration ratio and the second organic volatile concentration can be calculated to determine the product value as the reference organic volatile concentration. In some possible examples, the preset volatile concentration correspondence relationship between the vehicle where the target interior is located and the preset organic volatilization device is a preset functional relationship (for example, a linear functional relationship), then the second organic volatile concentration can be substituted into the preset functional relationship to determine the reference organic volatile concentration.

[0035] Step 105 , calculating the difference between the first organic matter volatile concentration and the reference organic matter volatile concentration to obtain a volatile organic matter contribution value of the target interior.

[0036] It should be noted that the VOC contribution value in this embodiment can be positive or negative. In the case of a positive value, it indicates that the target interior emits VOC into the vehicle, and in the case of a negative value, it indicates that the target interior absorbs VOC in the vehicle. For example, if the VOC contribution value is 35 μg / m 3 , indicating that the target interior emits VOC into the car. If the volatile organic compound contribution value is -10μg / m 3 , indicating that the target interior adsorbs VOCs in the car.

[0037] After determining the reference organic volatile concentration, the volatile organic compound contribution value of the target interior is determined according to the first organic volatile concentration and the reference organic volatile concentration. For example, the difference between the first organic volatile concentration and the reference organic volatile concentration can be calculated, and the difference can be determined as the volatile organic compound contribution value. For example, if the preset time period is 16h, the determined first organic volatile concentration is C1, and the volatile organic compound contribution value of the target interior is C_16h, then C1-C_16h can be used as the volatile organic compound contribution value of the target interior. For example, the first organic volatile concentration and the reference organic volatile concentration can be input into a pre-built convolutional neural network model to obtain the volatile organic compound contribution value of the target interior output by the model.

[0038] Therefore, in the present technical solution, on the one hand, the interior contained in the sampling container is only a target interior, so the volatile organic compound contribution value can be determined for each individual interior, and the volatile organic compound contribution value of the target interior can be obtained by only measuring the target interior once in the sampling container, thereby avoiding the problem of VOC gradually emitting and consuming deviating from the initial state due to multiple measurements; on the other hand, the concentration environment of volatile organic compounds of all interiors in the vehicle is simulated based on the second organic matter volatilization concentration volatilized by the preset organic matter volatilization device, thereby ensuring that the target interior is determined under the influence of the concentration environment of volatile organic compounds of all interiors in the vehicle. The volatile organic compound contribution value of the interior decoration ensures the accuracy of the volatile organic compound contribution value of the target interior decoration; on the other hand, a relatively accurate volatile organic compound contribution value of each interior decoration to the VOC in the vehicle can be obtained in a relatively short time. For example, 10 interior decorations are placed in 10 sampling containers respectively, and a corresponding preset organic compound volatilization device is placed in each sampling container, wherein the corresponding relationship between the preset organic compound volatilization devices placed in different sampling containers and the preset volatile compound concentration of the vehicle may be completely the same or may not be completely the same. Therefore, the volatile organic compound contribution values ​​of 10 interior decorations can be obtained after the preset time period, with low cost and high efficiency.

[0039] In summary, the detection and processing method of volatile organic compounds in the embodiment of the present disclosure obtains the first organic matter volatilization concentration of the sampling container after a preset time period, wherein the sampling container contains a target interior and a preset organic matter volatilization device, obtains the second organic matter volatilization concentration corresponding to the preset time of the preset organic matter volatilization device, obtains the preset volatile matter concentration correspondence relationship between the preset organic matter volatilization device and the vehicle where the target interior is located, and then, according to the preset volatile matter concentration correspondence relationship, the second organic matter volatilization concentration is calculated and processed to obtain the reference organic matter volatilization concentration, and the first organic matter volatilization concentration and the reference organic matter volatilization concentration are calculated to obtain the volatile organic matter contribution value of the target interior. In this technical solution, the preset organic matter volatilization device is used to provide the target interior in the sampling container with a VOC environment that can simulate the whole vehicle, so that the VOC emission state of the target interior in the sampling container is the same as its emission state in the whole vehicle, and then the emission end point concentration of the VOC of the target interior after the preset time period is subtracted from the emission end point concentration of the VOC emission device in the preset time period to obtain the actual volatile organic matter contribution value of the target interior to the VOC in the vehicle. As a result, the efficiency and accuracy of determining the contribution value of volatile organic compounds in interior decoration are improved.

[0040] As mentioned in the above embodiments, the preset organic volatilization device is used to indirectly simulate the VOC environment of the vehicle. Therefore, it is very important to ensure the reliability of the corresponding relationship between the preset organic volatilization device and the preset volatile concentration of the vehicle where the target interior is located. In the actual application scenario, the sampled organic volatilization concentration of the vehicle in multiple sampling time periods is preliminarily determined, and the organic volatilization device is made based on the sampled organic volatilization concentration. The organic volatilization device is used to simulate the organic volatilization environment of the preset vehicle. Among them, it should be emphasized that if the preset vehicle belongs to the research and development stage, it is considered that the organic volatilization trend of the vehicle over time is similar, but the absolute value of the concentration is different (the absolute value of the concentration can be obtained by any possible method such as simulation model calculation). For example, at 25 degrees, different models basically reach the highest concentration at 16h, and the concentration change trend is first fast and then slow. Therefore, by constructing the preset volatile concentration corresponding to different models, it can be realized that even if there is no real vehicle to provide the sampled organic volatilization concentration, the organic volatilization environment can be simulated. Furthermore, after setting up the preset organic matter volatilization device, a new preset organic matter volatilization device and the target interior are placed in the sampling container to obtain the contribution value of the target interior to the volatile organic matter in the whole vehicle.

[0041] How to set up the organic matter volatilization device is described below with reference to specific embodiments.

[0042] In one embodiment of the present disclosure, referring to Figure 2 Before obtaining the corresponding relationship between the preset organic matter volatilization device and the preset volatile matter concentration of the vehicle where the target interior is located, the method further includes:

[0043] Step 201 : determining a plurality of sampling time periods, wherein the length of each sampling time period is less than or equal to the length of a preset time period.

[0044] It can be understood that in the embodiments of the present disclosure, the time length of multiple sampling time periods is less than or equal to the time length of the preset time period, that is, the time length of the preset time period is divided into multiple sampling time periods, wherein the multiple sampling time periods can be determined according to the VOC concentration change trend in the vehicle, and the VOC concentration change trend curve corresponding to the preset time period is determined, and the VOC concentration change trend curve corresponds to the VOC concentration at each time point in the preset time period. For example, a feature point with a large concentration change rate of VOC in the vehicle can be determined according to experimental data, and the sampling time period is determined according to the time point corresponding to the feature point. For another example, multiple feature points can be determined according to a preset time interval, and the sampling time period can be determined according to the time point corresponding to the feature point.

[0045] For example, refer to Figure 3 If the preset time period is 16 hours, the VOC concentration trend is as follows Figure 3As shown in the middle curve, sampling points 1-7 can be selected from the curve. In particular, the time point corresponding to sampling point 1 is 0h, the time point corresponding to sampling point 2 is 2h, the time point corresponding to sampling point 3 is 4h, the time point corresponding to sampling point 4 is 6h, the time point corresponding to sampling point 5 is 8h, the time point corresponding to sampling point 6 is 12h, and the time point corresponding to sampling point 7 is 16h.

[0046] Step 202 , collecting the concentration of volatile organic matter sampled in each sampling time period in the vehicle.

[0047] After the sampling time period is determined, the concentration of sampled organic volatiles in the vehicle after each sampling time period is collected. For example, the concentration of sampled organic volatiles in the air in the vehicle is collected at different times such as 0h, 2h, 4h, 6h, 8h, 12h, and 16h to obtain C_0h, C_2h, C_4h, C_6h, C_8h, C_12h, and C_16h.

[0048] Step 203, adjusting the preset organic volatilization device according to the sampled organic volatilization concentration, so that the correspondence between each sampled organic volatilization concentration and the third organic volatilization concentration is the preset volatile concentration correspondence, wherein the third organic volatilization concentration is the adjusted organic volatilization concentration of the preset organic volatilization device in the corresponding sampling time period.

[0049] In this embodiment, the preset organic volatilization device is adjusted according to the sampled organic volatilization concentration, so that the correspondence between each sampled organic volatilization concentration and the third organic volatilization concentration of the adjusted preset organic volatilization device after the corresponding sampling time period is the preset volatile concentration correspondence. In other words, it is ensured that the preset organic volatilization device not only satisfies the preset volatile concentration correspondence with the VOC concentration environment in the vehicle in the preset time period, but also satisfies the preset volatile concentration correspondence with the VOC concentration environment in the vehicle at multiple time points reaching the preset time period, that is, the preset organic volatilization device also simulates the VOC emission trend in the vehicle, thereby ensuring the accuracy of the volatile organic contribution value of the target interior obtained by the above measurement.

[0050] For example, if the preset volatile matter concentration correspondence is a preset volatile matter concentration ratio, and the preset time period is 16 hours, then the time points corresponding to the sampling time period are 0 hours, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, and 16 hours, and the preset organic matter volatilization device includes a preset organic matter volatilization device 1, a preset organic matter volatilization device 2, and a preset organic matter volatilization device 3, wherein the ratio of the VOC concentration environment in the vehicle to the preset volatile matter concentration of the preset organic matter volatilization device 1 is 1, the ratio of the VOC concentration environment in the vehicle to the preset volatile matter concentration of the preset organic matter volatilization device 1 is 0.5, and the ratio of the VOC concentration environment in the vehicle to the preset volatile matter concentration of the preset organic matter volatilization device 1 is 1.5. As shown in Table 1 below, the corresponding relationship between the sampled organic matter volatile concentration collected in each sampling time period and the third organic matter volatile concentration of the adjusted preset organic matter volatilization device after the corresponding sampling time period is the preset volatile matter concentration corresponding relationship:

[0051] Table 1

[0052]

[0053]

[0054] Therefore, in this embodiment, when the preset organic volatilization device is the preset organic volatilization device 3, after the second organic volatilization concentration is obtained, C_16h*0.5 can be calculated to obtain the reference organic volatilization concentration and the like.

[0055] It should be noted that in different application scenarios, the method of adjusting the preset organic volatilization device according to the sampled organic volatilization concentration is different. In some possible embodiments, the initial organic volatilization concentration of the volatile organic reagent contained in the preset organic volatilization device is determined, and the initial organic volatilization concentration is related to the type of the volatile organic reagent. According to the initial organic volatilization concentration, the sampled organic volatilization concentration and the corresponding sampling time period, the preset organic volatilization device is adjusted. For example, the initial organic volatilization concentration, the sampled organic volatilization concentration and the corresponding sampling time period can be input into the corresponding preset deep learning model, and the element operation parameters of the organic contribution rate adjustment element corresponding to each sampling time period output by the deep learning model are determined, and the organic contribution rate adjustment element is adjusted according to the element operation parameters, wherein the organic contribution rate adjustment element can include a gas semipermeable membrane, and the corresponding element operation parameters can include the porosity and number of layers of the gas semipermeable membrane, etc., and the organic contribution rate adjustment element can include a container cover, and the corresponding element operation parameters can be the container cover opening and closing angle, etc.

[0056] For example, the initial volatile organic contribution rate of the volatile organic reagent can be obtained, the concentration difference between the initial organic volatilization concentration and the sampled organic volatilization concentration can be calculated, the actual volatile organic contribution rate of the volatile organic reagent can be calculated according to the concentration difference and the corresponding sampling time period, and the preset organic volatilization device can be adjusted according to the initial volatile organic contribution rate and the actual volatile organic contribution rate. For example, the component operation parameters of the organic contribution rate adjustment component in the preset organic volatilization device can be determined according to the initial volatile organic contribution rate and the actual volatile organic contribution rate, and the organic contribution rate adjustment component can be adjusted according to the component operation parameters, wherein the ratio of the concentration difference and the corresponding sampling time period can be calculated, and the ratio is the actual volatile organic contribution rate, the difference between the initial volatile organic contribution rate and the actual volatile organic contribution rate is calculated, and the component operation parameters of the organic contribution rate adjustment component are adjusted according to the difference to ensure that the adjusted organic contribution rate of the preset organic volatilization device is the actual volatile organic contribution rate, etc.

[0057] In summary, the detection and processing method of volatile organic compounds in the disclosed embodiment makes a preset organic volatilization device that conforms to the VOC change trend in the whole vehicle, and uses this device to simulate the whole vehicle VOC environment for the relevant interior in the sampling container, so that the VOC emission state of the interior in the sampling container is the same as its emission state in the whole vehicle, and then the endpoint concentration of the preset organic volatilization device is subtracted from the endpoint concentration of the VOC emission of the interior after a preset time period to obtain the actual volatile organic compound contribution value of the relevant interior to the vehicle. The efficiency and accuracy of determining the contribution value of volatile organic compounds are improved.

[0058] In order to implement the above embodiments, the present disclosure also proposes a volatile organic compound detection and processing device.
