Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sensors, in particular to a sound and gas composite detection system. BACKGROUND

[0002] Some people with allergic reactions will produce an immune response when inhaling specific allergens, and excessive histamine is produced in the body to produce allergic symptoms. Excessive secretion of histamine can cause itching and pain in the human body or skin swelling, making the human body in a state of non-disease symptoms of pain. This state generally occurs when the human body contacts specific allergens.

[0003] CN104894278A discloses a rapid and efficient screening method for detecting food allergens. The screening method comprises the following steps: extracting DNA of the sample, performing PCR amplification detection on the DNA of the sample, screening 16 kinds of allergen components in a single reaction tube at one time based on the multi-channel property of the PCR instrument, and determining the allergen components through two rounds of PCR.

[0004] The prior art mainly detects the allergens of the human body. The subjective judgment of the human body avoids allergens that may harm the human body. Many allergens belong to substances that often appear in the living environment, such as pollen, willow catkins, and large particle dust.

[0005] For the monitoring method of allergen in the environment, the Chinese patent with publication number CN109147957A relates to a personalized monitoring method and device of allergen in air, the method is applied to an environmental monitoring equipment server, the environmental monitoring equipment server is in communication connection with an intelligent client, and the method comprises the following steps: obtaining the physical information of a user through the intelligent client, thereby obtaining the first allergen information of the user and the sensitivity information of the first allergen information; obtaining a first allergen database through the environmental monitoring equipment; obtaining the index information of the allergen in the first allergen database according to the first allergen database; obtaining the weighted value of the user to the first allergen according to the sensitivity information and the index information; and determining the first safety distance of the user to the allergen in air according to the weighted value. Alternatively, the Chinese patent with publication number CN106384008A discloses an allergic rhinitis prediction method based on an incremental neural network model, which comprises the following steps: establishing an allergic rhinitis daily data database; training a neural network model; collecting daily life data and sending it to a server and saving it to a user daily data record table; extracting the data of the day from the user daily data record table, forming an n-dimensional vector, and inputting the normalized data into an allergic rhinitis pathological neural network model to predict the probability of allergic rhinitis; an intelligent home allergic rhinitis care device judges whether the probability of allergic rhinitis is greater than 0.5; if the user is determined to have allergic rhinitis, the user goes to the hospital for examination, and the examination result is transmitted back to the server through the intelligent home allergic rhinitis care device, and the server judges whether the examination result is correct; when the examination result is incorrect, an incremental algorithm is executed to dynamically correct the neural network model. Due to the complexity of human living environment, the conversion error of the probability that the human body may touch the allergen is extremely large by summarizing the data of the daily environment. When the system makes a mistake, the use of wrong medicine will harm the human body.

[0006] Based on this, the present application relates to a sound gas composite detection system which can accompany the human body in the form of a mobile terminal and monitor the environment of the human body for allergens, and generate corresponding protection measure suggestions through the detection results of different volumes of allergens.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, the applicant has studied a large number of literatures and patents when making the present application, but due to the limited space, all the details and contents have not been listed in detail, which does not mean that the present application does not have these characteristics of the prior art, on the contrary, the present application has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0008] In view of the problems of the prior art, the present application provides a sound and gas composite detection method. The method comprises stress reaction risk assessment, which comprises first cognitive identification of the environment in which the tester is located, and finding stress reaction triggers of the tester based on the first cognitive identification result. The tester can master the changes in the environment in which he / she is located through real-time monitoring of the environment by the bionic sensory element formed by precise machinery, so as to timely respond to the changes in the environment that may appear allergens.

[0009] The first cognitive identification is that the first cognitive module pre-identifies odor factors in the environment in which the tester is located based on the environment, which is used to obtain the odor factors in the environment in which the tester is located as the first early warning evaluation parameter for screening the stress reaction triggers of the tester. The first cognitive module sends the first early warning evaluation parameter and the past medical history of the tester obtained by sending a query request to the historical database with the permission of the tester to the risk management module of the tester. For changes in the environment, odor factors can be preferentially diffused and captured by odor sensors. The first cognitive module can monitor the odor factors in the environment in which the tester is located in real time. Based on the perception of the odor factors in the environment in which the tester is located, the tester can timely find the appearance of allergens. Specifically, the first cognitive module receives odor factors and generates first early warning evaluation parameters. The stress history or stress reaction trigger record of the tester is obtained through the historical database, so as to determine the stress reaction triggers of the tester, which can be allergens. Preferably, the first cognitive module is equipped with a gas sensor. The gas sensor collects odor molecules in the environment and generates different sizes of current corresponding to different odor molecules based on the influence of the odor molecules in the environment on the current transmission. The gas sensor can monitor the gas concentration, gas species or gas flow rate in the environment, so that the processing module in the back end can comprehensively evaluate the odor in the environment.

[0010] The odor detection can be passive detection based on chemical catalysts under certain technical choices, that is, only when specific odor molecules enter the first cognitive module and react with specific chemical catalysts will they be detected by the specific detection circuit of the first cognitive module, which means that the first cognitive module used in the present scheme is very power-saving even in the long-term search mode for odor molecules. For the living environment of the tester who needs to face real-time changes, the self-sustaining, endurance and maintenance-free of the device are greatly improved. At the same time, the first cognitive module needs to be equipped on a mobile terminal to monitor the environment in which the tester is located in real time, so the first cognitive module equipped on the mobile terminal can reduce the consumption of the power of the mobile terminal.

[0011] The risk management module assesses the stress level of the test subject based on the first early warning assessment parameter and the test subject's medical history, and confirms the coping measures that the test subject needs to take in the current environment based on the stress level. The stress reaction risk assessment based on the first cognitive identification includes the coping measures that the test subject needs to take in the current environment. The first cognitive module can access the historical database storing the medical history of the test subject based on the authorization of the test subject. The risk management module classifies the odor factor into three categories, i.e., odor factor of non-risk factor, odor factor of weakly associated risk factor, and odor factor of strongly associated risk factor, by comparing the odor factor with the historical data that can cause the medical history of the test subject.

[0012] The odor factor of non-risk factor is the odor factor that does not cause the stress reaction of the test subject. If the collected odor factor is neither the same nor the same category as the trigger of the medical history of the test subject, the odor factor is a non-risk factor.

[0013] The odor factor of weakly associated risk factor is the odor factor that is the same category as the trigger of the medical history of the test subject. Specifically, allergens account for a large part of the triggers that cause the stress reaction of the test subject, such as irritating gas. The gas can be the smell of disinfectant, paint, perfume, play dough, tire, etc. Based on the above-mentioned main chemical components, it is analyzed whether the components in the collected gas factor are the same category as the above-mentioned chemical components. When the collected chemical components are the same category as the trigger of the medical history, the odor factor is an odor molecule of weakly associated risk factor.

[0014] The odor factor of strongly associated risk factor is the odor factor that is the same as the trigger of the medical history of the test subject. By comparing with the trigger of the medical history, when the odor factor consistent with the trigger appears, the odor factor is an odor factor of strongly associated risk factor. For example, the smell of tire burning is the trigger of the stress reaction that the test subject has ever experienced. When the collected odor factor is consistent with the smell of tire burning, the odor factor is an odor factor of strongly associated risk factor.

[0015] According to a preferred embodiment, the coping measures include three categories. Based on the odor factor of different levels of risk factors, the test subject can take different protective measures. Each protective measure corresponds to an odor factor of a level of risk factor.

[0016] According to a preferred embodiment, the tester is in an environment containing odor factors of non-risk factors and voluntarily chooses to be in the environment based on the odor factor categories displayed by the detection system and perceives the environment with his five senses. The risk management module classifies the odor factors as non-risk factors based on the comparison of the triggers from the prior medical history with the collected odor factors. The risk management module is capable of sending the detection results of the environmental odor to the tester through the mobile terminal. When the odor factors in the environment are non-risk factors, the tester is able to stay in the environment for a long time without any risk of stress reaction.

[0017] According to a preferred embodiment, the tester is in an environment containing odor factors of weakly associated risk factors with the triggers from the tester's prior medical history and receives the suggestion of physical protection provided by the risk management module based on the odor factor categories displayed by the detection system, thereby reducing the aggregated concentration of the odor factors of risk factors with the triggers from the tester's prior medical history in the tester's respiratory system. When there are odor factors of weakly associated risk factors in the current environment, it means that some or all of the odor factors in the environment have the potential to cause stress reaction in the tester. For example, the chloride in 84 disinfectant is the main component in 84 disinfectant that causes allergic reaction. When the collected odor factor is similar in structure or is of the same family as the chloride, the odor factor has the potential to cause stress reaction in the tester, but because the structural similarity is not complete, the respiratory reaction is not sensitive in the early stage and in small quantities. When the odor factor reaches a certain quantity and aggregates in the respiratory system, the odor factor causes stress reaction. For this odor factor, the most effective protective measure is to physically isolate the odor factor from the respiratory tract. Because the detection precedes the generation of allergic symptoms, effectively isolating the odor factor from the respiratory tract through medical devices can reduce the occurrence of stress reaction. Preferably, the way to determine odor factors of the same family can be that the basic chemical formula is the same, for example, odor factors composed of benzene ring and odor factors composed of isomers of benzene ring (including chiral molecules) are of the same family. Chemical substances such as chiral molecules in isomers are (S)-carvone with coriander flavor and (R)-carvone with spearmint flavor.

[0018] Even if two chemical molecules produce different tastes, but due to their structures mostly derived from the same basic chemical formula, such as benzene or trihydroxy, these substances can produce special effects on human body, and the mechanism of the two chemical molecules acting on human body is the same. Both of the two chemical molecules can cause the stress reaction of human body in a stable environment. The present application improves the detection accuracy and coverage of allergens of the tester by analyzing the chemical formula of the odor factor causing the stress reaction of human body and classifying it, and then classifying by similarity of the same family. When dealing with complex living environment, the classification basis of the stress reaction inducer is not the type of living goods, but the chemical formula of allergen. On the one hand, such classification method can greatly improve the detection accuracy, avoid the same chemical substance in different living goods which cannot be found, and lead to the situation that the tester cannot be prompted to avoid allergen in time; on the other hand, due to the increase of environmental complexity, the comparison of living goods as stress reaction inducer will increase the storage space of the system and the system operation time for comparison and evaluation, and further complicate the processing process of the system.

[0019] According to a preferred embodiment, the tester completes the physical and drug protection coping measures of stress reaction based on the odor factor type displayed by the detection system when the tester is in an environment containing odor factors with the same risk factors as the inducer of the tester's past medical history, so as to block the occurrence of the stress reaction of the tester. The odor factor with the same risk factors as the inducer of the tester's past medical history has directly induced the stress reaction of the tester in the past, so when the tester contacts the odor factor of this type again, the odor factor can directly induce the stress reaction of the tester. When the collected odor factor is the same as the inducer of the tester's past medical history, the risk management module generates a corresponding suggestion of protection measures. In order to prevent the occurrence of the stress reaction of the tester, on the one hand, the possible immune overreaction in the body of the tester is blocked by taking medicine; on the other hand, the odor factor causing the stress reaction is prevented from entering the respiratory system of the tester by wearing a mask and other physical blocking means. Based on the detection result sent by the risk management module to the mobile terminal, the tester can also change the route of travel to avoid excessive inhalation of odor factors and aggravate the stress reaction.

[0020] The accumulation of the amount of odor factors in the respiratory system of the tester can cause the stress reaction of the tester to be aggravated. For some routes of odor factors that can cause the stress reaction of the tester to be aggravated, the tester mostly needs to select another route with less or even no odor factors. When encountering such odor, the tester can only perceive the existence of the odor by inhaling. When judging the dispersion direction and concentration of such odor factors by the sense of smell, the tester has already accumulated a certain amount of such odor factors in the respiratory system, so even if the tester knows how to walk to avoid the odor factors causing the stress reaction, it is useless.

[0021] The first cognitive module involved in the detection system can monitor the amount of odor factors, i.e. odor concentration, in the environment. Preferably, the first cognitive module is circumferentially assembled with a plurality of odor sensors. The circumferentially distributed odor sensors can monitor the odor spreading in 360° direction. Since the first cognitive module is assembled on the mobile terminal, the handheld mobile terminal can monitor the odor concentration in the three mutually perpendicular coordinate axes X, Y and Z directions formed in the position centered on the tester. As shown in Figure 1 the figure, the gas spreads in the three-dimensional space. The first cognitive module one or more odor sensors collect the amount of such odor factors, so as to confirm the coordinate position of the odor factors on the X axis and the Y axis. When the height of the mobile terminal is lowered, it can still obtain the coordinate position of the odor factors on the X axis and the Y axis. By judging the source of the odor factors, the tester can avoid the position coordinates. Preferably, the first cognitive module is a passive detection module, i.e. as the tester moves, it can update the spreading position and concentration value of the odor factors that cause the tester's stress reaction in real time. According to the concentration value and position change of the odor factors, the tester can effectively avoid the spreading source of the odor factors to reduce the amount of inhaled odor factors.

[0022] According to a preferred embodiment, the stress reaction of the tester includes allergic symptoms, respiratory system rejection symptoms and cold symptoms.

[0023] IU / ml is a commonly used medical measurement unit, which refers to the number of serum specific IgE international units per milliliter. The allergen value and grade refer to the classification of the measured value of the measured specific IgE. According to the standard calibration of the World Health Organization (WHO), the measured value is classified into 0-Ⅵ grades, with the unit of IU / ml. Specifically, the following grades are classified:

[0024] 0 grade: <0.35 IU / ml, no or undetectable serum specific IgE, clinically indicating no allergy to the allergen;

[0025] Grade I: 0.35-0.7 (IU / ml), low serum specific IgE content, clinically indicating suspected or mild allergy to the allergen;

[0026] Grade II: 0.7-3.5 (IU / ml), serum specific IgE level is medium, clinically indicating mild allergy to the allergen;

[0027] Grade III: 3.5-17.5 (IU / ml), high serum specific IgE level, clinically indicating moderate allergy to the allergen;

[0028] Grade IV: 17.5-50 (IU / ml), the serum specific IgE level is very high (+), and the clinical significance is that the patient has moderate to severe allergy to the allergen;

[0029] Grade V: 50-100 (IU / ml), the serum specific IgE level is very high (++), and the clinical significance is that the patient has severe allergy to the allergen;

[0030] Grade VI: > 100 (IU / ml), the serum specific IgE level is very high (+++), and the clinical significance is that the patient has particularly severe allergy to the allergen.

[0031] When the odor factor is the same species of allergen that can cause the patient to have moderate or severe allergy, even if the tester inhales a small amount of odor factor, the tester can also have an allergic reaction. The main manifestation of the allergic reaction is that the tester sneezes.

[0032] When the temperature is low or the individual immunity of the tester is weak, the tester will also sneeze due to a cold. Unlike the continuous sneezing caused by an allergic reaction, the number of sneezes caused by a cold is within three, and the duration is not long.

[0033] According to a preferred embodiment, the tester provides permission to send a query request to the historical database, which includes the following steps:

[0034] The comparison between the tester's identity information and the face information and / or fingerprint information of the tester's mobile terminal is completed; when the comparison result shows that the operator of the query request is consistent with the identity information of the object stored in the historical database, the historical database allows the first cognitive module to query the case content stored therein; when the comparison result shows that the operator of the query request is not consistent with the identity information of the object stored in the historical database, the historical database rejects the query request of the first cognitive module and sends a personal information error prompt based on the mobile terminal.

[0035] Based on the differentiation of different types of stress reactions of the tester, to determine whether the tester needs to avoid the odor factor transmission source, the system also includes a second cognitive module capable of second cognitive identification. The second cognitive module can collect sound information in the environment. Preferably, the second cognitive module comprises a sound sensor. The sound sensor can collect the sound in the environment and convert the collected sound signal into data that can be recognized by the back-end processing module.

[0036] According to a preferred embodiment, the stress reaction risk assessment further comprises a second cognitive appraisal, the second cognitive module monitors the frequency of the stress reaction of the subject based on the stress level assessment. The second cognitive module collects the sound information generated by the subject and sends the sound information to the risk management module. The risk management module judges the frequency of the repetitive sound segment (i.e. the frequency of sneezing) and confirms that the subject sneezes due to allergy rather than cold when the frequency or repetition rate exceeds a second threshold. When the collected chemical factors are determined to have a weak correlation with the allergen in the case content based on the comparison of the chemical structure, the second cognitive module collects the sneezing sound of the subject to confirm whether a stress reaction occurs. When the subject sneezes continuously for more than 30 seconds, the risk management module generates a second cognitive appraisal confirming that the subject has an allergic stress reaction based on the sound collected by the second cognitive module. The stress reaction risk assessment confirms that the subject has an allergic stress reaction based on the first cognitive appraisal and the second cognitive appraisal. The stress level assessment is divided into three levels, namely non-risk, weak correlation and strong correlation.

[0037] According to a preferred embodiment, the physical protection is to isolate the sensory organs and external odor factors connected to the respiratory system by physical means. Preferably, the subject wears a mask to isolate the sensory organs and external odor factors connected to the respiratory system.

[0038] According to a preferred embodiment, a sound-gas composite detection system. The system at least includes a first cognitive module and a risk management module, wherein the first cognitive module and the risk management module are configured to perform a stress reaction risk assessment, the stress reaction risk assessment at least includes a first cognitive appraisal for the subject in the environment, and finds the stress reaction inducement of the subject based on the first cognitive appraisal result. The first cognitive appraisal is that the first cognitive module pre-appraises the odor factors in the environment based on the subject in the environment, which is used as the first early warning assessment parameter for screening the odor factors in the environment where the subject is located as the inducement for the occurrence of stress reaction of the subject. The first cognitive module sends the first early warning assessment parameter and the past medical history of the subject obtained by sending a query request to the historical database with the permission provided by the subject to the risk management module of the subject. The risk management module realizes the stress level assessment of the subject based on the first early warning assessment parameter and the past medical history of the subject, and confirms the coping measures to be taken by the subject in the current environment based on the stress level. The stress reaction risk assessment generated based on the first cognitive appraisal contains the coping measures to be taken by the subject in the current environment. BRIEF DESCRIPTION OF DRAWINGS

[0039] Figure 1 is a schematic diagram of the gas collection provided by the present application. DETAILED DESCRIPTION

[0040] The following will be described in detail in conjunction with the drawings. The following will be described in detail in conjunction with the drawings.

[0041] In recent years, the incidence of allergic rhinitis shows a trend of increasing year by year. About 10% to 40% of people in the world are troubled by rhinitis, 20% of adults in the United States suffer from allergic rhinitis, the prevalence rate in China has increased from 11.1% to 17.6%, and Japan has as high as 25%, which is called a rhinitis country. Among the symptoms of allergic rhinitis, the allergic symptoms caused by dust or pollen are often concerned by people, while the gas allergic symptoms are often ignored, the main reason is that dust and pollen, such as allergens, are in granular form and the phenomenon is more obvious, which can be observed by naked eye, while gas allergy cannot be observed by naked eye. When people perceive the existence of allergen gas through the nasal cavity, the allergen has entered the human respiratory system. The unrecognizability of gas allergen makes people unable to avoid it in advance through sensory judgment, so gas allergy often occurs secretly and quickly.

[0042] There is a paint brush painting scene in the environment.

[0043] The first cognitive module collects odor factors of the environment where the tester is located. The collected odor factors are sent to the risk management module as the first early warning evaluation parameter.

[0044] The tester uses the mobile terminal carried by himself to authorize the query request sent by the first cognitive module. The mobile terminal includes a mobile phone, a tablet or a host. The tester scans the facial information or the fingerprint information, thereby confirming the authorization access permission to the first cognitive module. When the characteristic information of the tester is the same as the identity of the person stored in the historical database, it is considered that the authorization permission is authorized by the person himself, and the historical database allows the first cognitive module to query the case content of the tester stored in the historical database. The case content includes the allergic history of the tester, the allergen causing the allergic history, and the allergen detected by medical means. The first cognitive module obtains information related to the case content of the tester, and sends the information to the risk management module.

[0045] The risk management module obtains the odor factor information of the environment where the tester is located and the case content of the tester.

[0046] The risk management module compares the case content of the tester and the collected odor factor information. In this embodiment, there are three possible comparison results between the paint odor and the past medical history of the tester.

[0047] The first is that the allergen in the case content of the tester is completely different from the paint odor, that is, the paint odor will not cause the stress reaction of the tester. The collected odor factor in this result is determined as a non-risk factor odor factor.

[0048] The second is that the paint smell is the same as the allergen in the case content of the testee. The paint smell is mainly benzene and benzene series. Benzene and benzene series can also exist in glue, paint and adhesive. Benzene and benzene series existing in different daily use products can be the same compound or different isomers with benzene ring structure, which can cause stress reaction as an odor factor. When the test allergen or the allergen causing over-stress reaction in the case content of the testee is glue, paint and adhesive, the paint smell can be listed as the same substance inducing stress reaction by the risk management module. The collected odor factor in the result is determined as a weakly associated risk factor.

[0049] The third is that the paint odor factor is the same as the allergen in the case content of the testee. In the case content, the testee has a case of stress reaction caused by inhaling paint odor. The collected odor factor is the same as the allergen in the case content in chemical properties. The collected odor factor in the result is determined as a strongly associated risk factor.

[0050] Based on the transmitted information of the first cognitive module, the risk management module generates a first cognitive identification result. Based on the first cognitive identification result, the risk management module provides corresponding suggestions for the testee to avoid stress reaction.

[0051] According to a preferred embodiment, when the risk management module generates an odor factor of a weakly / strongly associated risk factor in the environment where the testee is located, the testee is suggested to change the route.

[0052] The method at least includes stress reaction risk assessment, which at least includes first cognitive identification for the environment where the testee is located, and finding the stress reaction inducement of the testee based on the first cognitive identification result.

[0053] Further, the stress reaction risk assessment can also include the second cognitive identification generated by the second cognitive module collecting the sound of the testee. Especially when the odor factor in the environment is the same as the allergen in the case content of the patient, it is difficult for the testee to determine whether to avoid the current environment. The second cognitive module collects the sound of the testee. When the odor factor collected by the first cognitive module is weakly associated with the case content, the second cognitive module starts to work.

[0054] The second cognitive module sends the collected sound to the risk management module. When the tester produces a continuous sneeze sound with a duration exceeding 30 seconds, the risk management module judges that the stress reaction of the current tester is an allergic reaction caused by an allergen as a trigger, and generates a second cognitive identification. The stress reaction risk assessment is based on the first cognitive identification and the second cognitive identification to judge that the tester produces a stress reaction caused by an allergen, and considers that the weakly associated odor factor is the trigger. The risk management module generates a suggestion. The suggestion content includes prompting the tester to wear a gas mask and detour.

[0055] According to a preferred embodiment, the physical protection is to isolate the sense organ connected to the respiratory system and the external odor factor by physical means. Based on the fact that the odor factor is a small molecule in free state, in this embodiment, the mask worn by the tester can be a gas mask provided with activated carbon, which can effectively isolate the sense organ connected to the respiratory system and the external odor factor.

[0056] The substance capable of causing stress reaction of human body involved in the present application can also be an odor harmful to the tester, such as smoke dust or burnt smell related to fire. The detection system in the present application can be used in a fire scene to provide information for identifying and judging the danger source for firefighters or other personnel participating in fire extinguishing. For example, a firefighter carries the system with him into a fire scene. The first cognitive module monitors the odor in the environment where the firefighter is located. The second cognitive module monitors the sound in the environment where the firefighter is located. When the firefighter enters the fire scene, the first cognitive module can provide visual route guidance for the firefighter through monitoring of smoke dust and burnt smell, i.e. when the firefighter's purpose is to enter the fire scene for rescue, the first cognitive module can provide a route away from a position with high concentration in the fire scene, so that the firefighter can avoid the danger source. When the second cognitive module detects a sound of a person calling for help, the risk management module generates a route with relatively low smoke or odor concentration based on the direction of propagation of the sound of a person calling for help, to help the firefighter quickly reach the calling position. Some fires may have electric sparks. In a visualized fire scene with relatively low concentration or other disaster scenes (such as explosion), the firefighter may not be able to perceive the danger of electric discharge on the route of travel at a safe distance, resulting in a decrease in the apparent distance of the firefighter in the disaster scene and a risk. The second cognitive module can monitor the discharge sound in the environment where the firefighter is located in real time. When the firefighter travels along the route generated by the risk management module based on the first cognitive identification generated by the first cognitive module, the second cognitive module generates a second cognitive identification to provide a basis for the risk management module to judge other danger sources in the environment. The risk management module generates a danger prompt of electric discharge based on the second cognitive identification, so that the firefighter can timely avoid the risk.

3. The system of claim 1, wherein, The first cognitive module can monitor the number of odor factors in the environment, i.e. the odor concentration, wherein the first cognitive module circumferentially comprises a plurality of odor sensors to monitor the odor propagating in 360° direction.

4. The system of claim 1, wherein, The coping measures match the stress level, so that the risk management module can generate corresponding coping measures based on each stress level. The coping measures match the stress level, so that the risk management module can generate corresponding coping measures based on each stress level.

5. The system of claim 1, wherein, The first cognitive module sends the past medical history of the tester obtained by sending a query request to the historical database by the tester to the risk management module of the tester, wherein the tester sending a query request to the historical database comprises the following steps: The tester's face information and / or fingerprint information of the mobile terminal are compared with the tester's identity information; when the comparison result shows that the operator sending the query request is consistent with the identity information of the object stored in the historical database, the historical database allows the first cognitive module to query the case content stored therein; when the comparison result shows that the operator sending the query request is inconsistent with the identity information of the object stored in the historical database, the historical database rejects the query request of the first cognitive module and sends a personal information error prompt based on the mobile terminal.

6. The system of claim 1, wherein, The stress reaction includes allergic symptoms, respiratory system rejection symptoms and cold symptoms.

7. The system of claim 1, wherein, The physical protection is to isolate the sensory organs and external odor factors connected with the respiratory system by physical means.

8. A method of using the sound gas compound detection system according to any one of claims 1 to 7, characterized in that, The method at least comprises: The stress reaction risk assessment at least comprises a first cognitive identification of the environment where the tester is located and a second cognitive identification generated by the second cognitive module collecting the tester's voice, and the stress reaction risk assessment confirms the occurrence of allergic stress reaction of the tester based on the first cognitive identification and the second cognitive identification; The first cognitive identification is a pre-identification of odor factors in the environment by the first cognitive module based on the environment where the tester is located, and the first cognitive module is used to obtain the odor factors in the environment where the tester is located as the first early warning evaluation parameter for screening the stress reaction occurrence inducement of the tester, and sends the first early warning evaluation parameter and the past medical history of the tester obtained by sending a query request to the historical database by the tester to the risk management module of the tester; The risk management module realizes the stress level assessment of the tester based on the first early warning evaluation parameter and the past medical history of the tester, and confirms the coping measures needed by the tester in the current environment based on the stress level; Based on the stress level assessment, the second cognitive module monitors the frequency of the occurrence of the stress reaction of the tester.
