[0072] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0073] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0074] The main solutions of the embodiments of this application are:

[0075] In this embodiment, for the convenience of description, the following description is made by taking the identification of gas safety inspection as the execution subject.

[0076] Due to the existing technology, when testing the gas to be tested, the staff can only test the gas concentration and gas composition in the current area to be tested. When gas abnormalities are detected, the staff cannot take timely precautions, and the construction safety is low.

[0077] The present application provides a solution to obtain the gas to be detected, use a gas sensor to detect the gas to be detected, obtain multiple gas types contained in the gas to be detected and the current gas concentration corresponding to each gas type, predict the future gas concentration of each gas type based on a preset gas concentration prediction model, the multiple gas types and the current gas concentration, and determine the gas safety inspection result of the gas to be detected based on the multiple gas types, the current gas concentration and the future gas concentration. The present application predicts the future gas concentration by using a preset gas concentration prediction model, and obtains the gas safety inspection result of the gas to be detected based on the future gas concentration and the current gas concentration. As a result, the staff can detect gas anomalies in advance and improve construction safety.

[0078] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a gas safety inspection device, etc. The following takes the gas safety inspection device as an example to illustrate this embodiment and the following embodiments.

[0079] Based on this, the present application embodiment provides a gas safety inspection method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the gas safety inspection method of the present application.

[0080] In this embodiment, the gas safety inspection method includes steps S100 to S400:

[0081] Step S100, obtaining the gas to be detected;

[0082] In this embodiment, the execution subject is a gas safety inspection device, which can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The gas safety inspection device includes a gas inspection sensor.

[0083] In this embodiment, the specific application scenario may be:

[0084] In a large enclosed space (construction area), the staff needs to conduct gas detection in the construction area to determine whether the gas in the construction area is safe. Then, the staff clicks the "Gas Safety Inspection" button. After the gas safety inspection device detects that the staff clicks the "Gas Safety Inspection" button, the gas safety inspection device uses a gas sampling device to sample gas (gas to be inspected) from the construction area, where the gas sampling device includes but is not limited to a gas sampling pump, an aspiration sampler, and the like.

[0085] Specifically, the step of obtaining the gas to be detected further includes steps S110 to S130:

[0086] Step S110, obtaining the area to be inspected;

[0087] It can be understood that the area to be inspected is the construction area.

[0088] Step S120, dividing the area to be inspected into blocks based on a preset area size to obtain multiple target areas;

[0089] It is understood that, first, the gas safety inspection equipment collects detailed data of the area to be inspected. The detailed data may include data of geographical and physical features such as terrain, buildings, roads, rivers, etc. The detailed data can be obtained through field measurements, satellite images, aerial photography, laser scanning (LiDAR), etc.

[0090] After the gas safety inspection equipment collects detailed data of the area to be inspected, the collected detailed data needs to be processed to extract useful information, and then, according to the useful information, the area to be inspected is divided into blocks to obtain multiple target areas;

[0091] It is understandable that before starting the block division, it is necessary to determine the size of each target area (preset area size). The preset area size can be set based on specific standards, needs or planning requirements. For example, in gas safety inspections, different area sizes may be preset based on the concentration of the gas and the error size of the gas safety inspection results. For a larger area, the gas is inspected using inspection equipment, and the error of the gas safety inspection result is larger and the reference is lower. For a smaller area, the gas is inspected using inspection equipment, and the error of the gas safety inspection is smaller, but the efficiency of the gas safety inspection is lower. Therefore, selecting a suitable target area can not only ensure the reliability of the inspection results, but also improve the inspection efficiency.

[0092] Step S130: extracting gas from any one of the multiple target areas to obtain gas to be detected.

[0093] It can be understood that after the gas safety inspection equipment divides the plan into blocks to obtain multiple target areas, the location for collecting gas in each target area is determined, and the gas safety inspection equipment uses a gas sampling device to extract gas at the gas collection location, and extracts gas from each target area to obtain the gas to be tested, wherein the gas extracted from each target area is stored separately.

[0094] Step S200, using a gas sensor to detect the gas to be detected, and obtaining multiple gas types contained in the gas to be detected and the current gas concentration corresponding to each gas type;

[0095] It is understood that, first, the gas sensor is placed in the gas to be tested so that it can contact the gas to be tested. After the gas sensor detects the gas, the gas sensor determines the type of gas based on the characteristics of the gas. For example, a certain gas sensor may be specifically used to detect carbon monoxide (CO), while another may be used to detect methane (CH4). After determining the gas type, the sensor also measures the concentration of each gas, that is, the proportion or content of each gas in the gas to be tested.

[0096] It should be noted that a gas sensor is a device that can convert the concentration of a gas into an electrical signal. It interacts with the gas in a physical or chemical manner, thereby detecting the presence and concentration of the gas. There are many types of gas sensors, and in this application, an electrochemical type gas sensor is used.

[0097] In addition, it should be noted that the gas sensor may be interfered by other gases during the actual detection process. Therefore, in this application, a gas sensor that only detects fixed gases is used, such as a gas sensor specifically for detecting carbon monoxide, a gas sensor specifically for detecting ammonia, etc.

[0098] Step S300, predicting the future gas concentration of each gas type based on a preset gas concentration prediction model, the multiple gas types and the current gas concentration;

[0099] It should be noted that the preset gas concentration prediction model is a mathematical model used to predict future gas concentrations based on input data (such as current gas concentration).

[0100] Step S400: determining a gas safety inspection result of the gas to be detected based on the multiple gas types, the current gas concentration and the future gas concentration.

[0101] It is understandable that after obtaining the multiple gas types, the current gas concentration, and the future gas concentration, the gas safety inspection device determines the concentration of oxygen in the gas to be inspected, determines whether there is toxic gas in the gas to be inspected, and determines the concentration of the toxic gas. Based on the oxygen concentration, whether there is toxic gas, and the concentration of the toxic gas when there is toxic gas, the inspection result of the gas to be detected is determined.

[0102] It should be noted that there are three types of gas test results, namely hypoxic gas, dangerous gas, and safe gas. Among them, hypoxic gas indicates that there is no non-toxic gas in the gas to be detected, or the concentration of toxic gas in the gas to be detected is within the safe concentration range, but the oxygen content is too low and not suitable for the survival of workers; dangerous gas indicates that there is toxic gas in the gas to be detected; safe gas indicates that the oxygen concentration in the gas to be detected is suitable for the survival of workers, and there is no non-toxic gas in the gas to be detected, or the concentration of toxic gas in the gas to be detected is within the safe concentration range.

[0103] Specifically, the step of determining the gas safety inspection result of the gas to be detected based on the multiple gas types, the current gas concentration and the future gas concentration further includes steps S410 to S440:

[0104] Step S410, judging whether there is toxic gas in the gas to be detected based on the multiple gas types;

[0105] It is understandable that toxic gases are those that are harmful to human health. They may cause damage to the respiratory system, nervous system, cardiovascular system, etc., and can even be fatal at a certain concentration. Toxic gases include: carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), ammonia (NH3), chlorine (Cl2), hydrogen cyanide (HCN), hydrogen sulfide (H2S).

[0106] It should be noted that toxic gases will only have an impact on human health when the concentration reaches a certain level. The impact of toxic gases with lower concentrations on human health is almost negligible.

[0107] Step S420, if it exists, determine whether the current concentration of the toxic gas is greater than or equal to the preset toxic gas concentration threshold, if the concentration of the toxic gas is greater than or equal to the preset toxic gas concentration threshold, determine that the inspection result of the current gas is dangerous gas; or, if the current concentration of the toxic gas is less than the preset toxic gas concentration threshold, determine the oxygen concentration in the current gas concentration, determine whether the oxygen concentration is less than the preset oxygen concentration threshold, if the oxygen concentration is less than the preset oxygen concentration threshold, determine that the inspection result of the current gas is hypoxic gas, if the oxygen concentration is greater than or equal to the preset oxygen concentration threshold, determine that the inspection result of the current gas is safe gas;

[0108] It can be understood that in this embodiment, when toxic gas exists in the gas to be detected and the concentration of the toxic gas is greater than or equal to the preset toxic gas concentration threshold, the test result is determined to be a dangerous gas, wherein the preset toxic gas concentration threshold refers to the minimum concentration value at which the toxic gas affects human health.

[0109] In this embodiment, when there is toxic gas in the gas to be detected, but the concentration of the toxic gas is less than the preset toxic gas concentration threshold, it is determined whether the oxygen concentration in the current gas concentration is less than the preset oxygen concentration threshold. If it is less than, the test result is determined to be hypoxic gas; if it is greater than or equal to, the test result is determined to be safe gas.

[0110] Step S430, obtaining a current gas safety inspection result based on the safe gas, the dangerous gas and the hypoxic gas;

[0111] It can be understood that after the test result is determined, the test result is saved as the current gas safety test result.

[0112] Step S440, determining the inspection result of the gas to be detected based on the current gas safety inspection result, the multiple gas types and the future gas concentration.

[0113] Specifically, the step of determining the inspection result of the gas to be detected based on the current gas safety inspection result, the multiple gas types and the future gas concentration further includes steps S441 to S442:

[0114] Step S441, determining a future gas safety inspection result based on the multiple gas types and the future gas concentration, wherein the future gas safety inspection result includes safe gas, dangerous gas and hypoxic gas;

[0115] It should be noted that the method for determining the second test result is the same as the method for determining the first test result. Please refer to the above introduction and will not be repeated later.

[0116] Step S442, based on the current gas safety test result and the future gas safety test result, determine the gas safety test result of the gas to be tested, wherein if the current gas safety test result and the future gas safety test result contain dangerous gas, then determine that the test result of the gas to be tested is dangerous gas; if the current gas safety test result and the future gas safety test result are both safe gas, then determine that the test result of the gas to be tested is safe gas; if the current gas safety test result and the future gas safety test result contain hypoxic gas, and no dangerous gas is present, then determine that the test result of the gas to be tested is hypoxic gas.

[0117] One or more technical solutions proposed in this application have at least the following technical effects:

[0118] The present application proposes a gas safety inspection method and related equipment. In the related technology, when inspecting the gas to be inspected, the staff can only inspect the gas concentration and gas composition of the current area to be inspected. When a gas abnormality is detected, the staff cannot take timely prevention measures, and the construction safety is low. In the present application, first, the gas safety inspection equipment obtains the gas to be detected, and then, the gas safety inspection equipment uses a gas sensor to detect the gas to be detected, and obtains the multiple gas types contained in the gas to be detected and the current gas concentration corresponding to each gas type. Furthermore, the gas safety inspection equipment predicts the future gas concentration of each gas type based on a preset gas concentration prediction model, the multiple gas types and the current gas concentration. Finally, based on the multiple gas types, the current gas concentration and the future gas concentration, the gas safety inspection result of the gas to be detected is determined.

[0119] It can be understood that in the present application, the gas safety inspection equipment uses a preset gas concentration prediction model to predict the future gas concentration, and obtains the gas safety inspection results of the gas to be detected based on the future gas concentration and the current gas concentration. As a result, the staff can detect gas abnormalities in advance and improve construction safety.

[0120] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 Before step S300, the gas safety inspection method further includes steps S310 to S360:

[0121] Step S310, obtaining a first gas concentration and a second gas concentration, wherein the second gas concentration is a gas concentration after n minutes of the first gas concentration;

[0122] It is understood that n can be 1, 2, 3, 4, 5, etc.

[0123] Step S320, determining a current gas concentration prediction model;

[0124] Step S330, predicting a third gas concentration n minutes after the first gas concentration based on the current gas concentration prediction model and the first gas concentration;

[0125] Step S340, subtracting the third gas concentration from the second gas concentration to obtain a gas concentration difference;

[0126] Step S350, determining whether the gas concentration difference is greater than a preset gas concentration threshold, and if the gas concentration difference is greater than the preset gas concentration threshold, adjusting the parameters of the current gas concentration prediction model;

[0127] It can be understood that if the gas concentration difference is greater than the preset gas concentration threshold, it indicates that the prediction ability of the current gas concentration prediction model does not meet the requirements; if the gas concentration difference is less than or equal to the preset gas concentration threshold, it indicates that the prediction ability of the current gas concentration prediction model meets the requirements.

[0128] Step S360, based on the current gas concentration prediction model after adjusting the parameters, returns to the step of predicting the third gas concentration n minutes after the first gas concentration based on the current gas concentration prediction model and the first gas concentration, until the gas concentration difference is less than or equal to the preset gas concentration threshold, and the preset gas concentration prediction model is obtained.

[0129] In this embodiment, the current gas concentration prediction model is trained to reduce the difference between the prediction result of the current gas concentration prediction model and the actual result, thereby improving the accuracy of the prediction value.

[0130] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those of the first and second embodiments can be referred to the above description, and will not be described in detail later. Figure 3 Before step S400, the gas safety inspection method further includes step A10:

[0131] Step A10, constructing an interface for displaying the gas safety inspection result of the gas to be detected, wherein the interface displays the gas safety inspection result of the gas to be detected, the multiple gas types, the current gas concentration, and the future gas concentration.

[0132] It can be understood that in this embodiment, the gas safety inspection equipment constructs an interface to display the gas safety inspection results of the gas to be detected, and the page displays the gas safety inspection results of each target area, the multiple gas types, the current gas concentration, and the future gas concentration.

[0133] It should also be noted that if the gas safety test result is a target area for hazardous gas, the target area will be marked in red; if the gas safety test result is a target area for oxygen-deficient gas, the target area will be marked in yellow; if the gas safety test result is a target area for safe gas, the target area will be marked in green.

[0134] In this embodiment, the gas safety inspection results of each target area are directly displayed, which is more intuitive and also makes it easier for the staff to understand the changes in the gas in the target area.

[0135] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the gas safety inspection method of the present application.
