Description

Technical Field

[0001] The present application relates to the field of leakage alarm technology, and in particular to a method, device, electronic equipment and medium for identifying VOCs unorganized leakage alarm. Background Art

[0002] Unorganized leakage of volatile organic compounds (VOCs) in chemical parks can lead to material loss, environmental pollution, and even huge casualties and damage accidents. In related technologies, distributed monitoring arranged inside the park can achieve real-time online monitoring of unorganized VOCs leakage, with high spatial and temporal resolution, and is also a hot spot for the development of VOCs monitoring technology.

[0003] However, since all monitoring points and leakage sources are usually in the same space, and the direction of unorganized leakage diffusion is affected by changes in the local wind field and is uncertain, when a leakage source leaks, not only one sensor will alarm, but multiple sensors nearby will alarm. When receiving alarms from multiple sensors, how to accurately confirm whether the alarming sensor is a joint alarm for the same leakage source or an independent alarm for different leakage sources has become an urgent problem to be solved. Summary of the invention

[0004] In order to accurately identify VOCs unorganized leakage alarms, the present application proposes a VOCs unorganized leakage alarm identification method, device, electronic equipment and medium.

[0005] In the first aspect of the present application, a method for identifying VOCs unorganized leakage alarms is proposed, the method comprising: obtaining a first monitoring point where an alarm occurs within a preset time; if the number of the first monitoring points is greater than one, then based on a preset coordinate system, determining a second monitoring point whose coordinate distance from the first monitoring point is less than a preset distance threshold; judging whether there is a third monitoring point between the second monitoring points where no alarm occurs; if so, judging whether the second monitoring point is a joint alarm based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system.

[0006] By adopting the above technical solution, after obtaining the first monitoring point where an alarm occurs within a preset time, if there is only one first monitoring point, it can be confirmed that the first monitoring point is an independent alarm. If the number is greater than one, it is necessary to perform distance judgment on every two monitoring points in the first monitoring point. The distance judgment is completed based on a preset coordinate system. The coordinate distance between every two monitoring points in the first monitoring point is calculated, and the monitoring point in the first monitoring point whose coordinate distance is less than the preset distance threshold is determined to be recorded as the second monitoring point. At this time, the second monitoring point can be pre-judged as a joint alarm, but the accuracy is not high at this time, and further confirmation is required. It is necessary to determine whether there is a third monitoring point between every two monitoring points of the second monitoring point where no alarm occurs. If not, it can be determined that the two monitoring points are a joint alarm. If there is a third monitoring point, it is necessary to determine whether the second monitoring point is a joint alarm based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system. In this way, it can be more accurately determined whether the monitoring point where the alarm occurs is a joint alarm or an independent alarm.

[0007] Preferably, determining whether there is a third monitoring point between the second monitoring points where no alarm occurs includes: obtaining coordinates corresponding to the third monitoring point in the preset coordinate system;

[0008] By determining whether the coordinates of the third monitoring point exist in a rectangular area formed by every two of the second monitoring points as diagonals, it is determined whether there is a third monitoring point between the second monitoring points where no alarm occurs.

[0009] Preferably, judging whether the second monitoring point is a joint alarm based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system includes:

[0010] Obtaining the dominant wind direction within the preset time;

[0011] Based on the preset coordinate system, determining a coordinate vector of every two monitoring points in the second monitoring points;

[0012] Calculating the angle between the dominant wind direction and the coordinate vector;

[0013] Whether the second monitoring point is a joint alarm is determined based on whether the absolute value of the angle is less than or equal to a preset angle threshold.

[0014] Preferably, the method further comprises: if there is no monitoring point between the second monitoring points where no alarm occurs, determining that the second monitoring point is a joint alarm.

[0018] The second judgment module is used to judge whether the second monitoring point is a joint alarm based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system when there is a third monitoring point between the second monitoring points where no alarm occurs.

[0019] Preferably, the first determination module is specifically used for:

[0020] Obtaining the coordinates corresponding to the third monitoring point in the preset coordinate system;

[0021] By determining whether the coordinates of the third monitoring point exist in a rectangular area formed by every two of the second monitoring points as diagonals, it is determined whether there is a third monitoring point between the second monitoring points where no alarm occurs.

[0022] Preferably, the second judgment module is specifically used for:

[0023] Obtaining the dominant wind direction within the preset time;

[0024] Based on the preset coordinate system, determining a coordinate vector of every two monitoring points in the second monitoring points;

[0025] Calculating the angle between the dominant wind direction and the coordinate vector;

[0026] Whether the second monitoring point is a joint alarm is determined based on whether the absolute value of the angle is less than or equal to a preset angle threshold.

[0027] Preferably, the device further comprises:

[0028] The second determining module is used to determine that the second monitoring points are joint alarms when there is no monitoring point between the second monitoring points where no alarm occurs.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Unorganized leakage of volatile organic compounds (VOCs) in chemical parks can lead to material loss, environmental pollution, and even huge casualties and damage accidents. In related technologies, distributed monitoring arranged inside the park can realize real-time online monitoring of unorganized leakage of VOCs, with high spatial and temporal resolution, and is also a hot spot for the development of VOCs monitoring technology. The VOCs distributed online monitoring system reasonably arranges distributed sensor points for the leakage sources that need to be monitored in the park. The sensors can collect the concentration of toxic and harmful gases in the air near them in real time and upload them to the cloud. Based on the VOCs concentration monitored in real time by these sensors, the location of the leakage source is calculated by designing a traceability model.

[0039] However, since all monitoring points and leakage sources are usually in the same space, and the direction of unorganized leakage diffusion is affected by changes in the local wind field and is uncertain, when a leakage source leaks, not only one sensor will alarm, but multiple sensors nearby will alarm. When receiving alarms from multiple sensors, how to accurately confirm whether the alarming sensor is a joint alarm for the same leakage source or an independent alarm for different leakage sources has become an urgent problem to be solved.

[0048] Figure 2 The flowchart of the VOCs unorganized leakage alarm identification method in the embodiment of the present application is shown. Figure 2 , the method comprising:

[0049] Step S201, obtaining the first monitoring point where an alarm occurs within a preset time.

[0050] In an embodiment of the present application, monitoring points have been pre-set in the park, and sensors are arranged at each monitoring point to collect the VOCs concentration in the surrounding air, and send the collected VOCs concentration to the cloud in the form of a concentration time series signal. The preset time can be pre-set according to the overall location layout of the monitoring points in the park. If the setting distance between the monitoring points is generally short, a shorter time period can be selected as the preset time, and the specific length is not limited. For example, in another feasible method, in the process of monitoring the concentration time series signals sent by the monitoring points in the park, it is found that an alarm event from the monitoring point begins at 12:00 on March 15, 2022, and continues until 13:00, and no new monitoring points with alarms are added. Then 12:00 to 13:00 on March 15, 2022 can be selected as the preset time.

[0051] In an embodiment of the present application, a reasonable concentration threshold is set in advance, and the concentration timing signal of each monitoring point is inspected in real time to obtain the interval segments where the concentration increases. The monitoring points corresponding to these interval segments are the first monitoring points where an alarm occurs. The number of first monitoring points can be one or more.

[0052] In some application embodiments, before inspecting the concentration timing signal, it also includes cleaning the concentration timing signal when it is received from the sensor at the monitoring point. This is because the sensor may enter erroneous data and some typical abnormal data based on its principle and performance when in use. The concentration timing signal data collected in real time is cleaned according to abnormal value deviation and preset cleaning rules to remove outliers and ensure that the collected concentration timing signal is correct and valid.

[0053] Step S202: if the number of the first monitoring points is greater than one, then based on a preset coordinate system, a second monitoring point whose coordinate distance among the first monitoring points is less than a preset distance threshold is determined.

[0054] In an embodiment of the present application, it is necessary to identify the first monitoring point where an alarm occurs to confirm whether the first monitoring point is an independent alarm or a joint alarm, wherein an independent alarm means that the leakage source detected by the monitoring point where the alarm occurs does not cause alarms at other monitoring points, and a joint alarm means that the leakage of one leakage source causes alarms at multiple monitoring points.

[0055] If the number of the first monitoring point is 1, it can be directly confirmed that the first monitoring point is an independent alarm monitoring point; if the number of the first monitoring point is greater than one, such as Figure 3 As shown in the figure, the circular mark represents the monitoring point, the blue mark represents the monitoring point without alarm, and the red mark represents the monitoring point with alarm; the hexagonal star mark represents the leakage source, and the alarm is SL1 , S L2 , S L3 There are three monitoring points, which constitute the first monitoring point of this application. It is necessary to identify the monitoring points for joint alarm and the monitoring points for independent alarm in the first monitoring point.

[0056] In step S202, a coordinate system is preset in the image of the distribution of the leakage source and monitoring points in the park. The coordinates of each monitoring point in the first monitoring point can be determined according to the preset coordinate system, and then the coordinate distance between every two monitoring points in the first monitoring point is calculated, and the coordinate distance is compared with the preset distance threshold, and the monitoring point whose coordinate distance is less than the preset distance threshold is determined to be recorded as the second monitoring point. At this time, the second monitoring point can be pre-judged as a joint alarm, but the accuracy is not high at this time, and further confirmation is required. If there are other monitoring points after removing the second monitoring point from the first monitoring point, the other monitoring points can be determined as independent alarm monitoring points.

[0057] Step S203, determining whether there is a third monitoring point between the second monitoring points where no alarm occurs.

[0058] In the embodiment of the present application, the determined second monitoring point needs to be further confirmed to more accurately determine which of the second monitoring points is the monitoring point for the joint alarm. The determination method is as in step S203 and step S204.

[0059] In some application embodiments, determining whether there is a third monitoring point between the second monitoring points where no alarm occurs is achieved by:

[0060] Step A1, obtaining the coordinates corresponding to the third monitoring point in the preset coordinate system.

[0061] Based on the preset coordinate system, the coordinates of all monitoring points in the third monitoring point are obtained.

[0062] Step A2, judging whether there is a third monitoring point between the second monitoring points where no alarm occurs, by judging whether there is a coordinate of the third monitoring point in a rectangular area formed by every two second monitoring points as diagonals.

[0063] In the preset coordinate system, a rectangle is formed by connecting every two monitoring points in the second monitoring point as a diagonal line, and it is determined whether the coordinates of the third monitoring point exist in the rectangle. In one example, Figure 4 As shown, it is necessary to determine whether point A and point B in the second monitoring point are joint alarms, then determine whether the rectangle formed by point A and point B contains the monitoring point T in the third monitoring point. The determination method is as follows: the point coordinates of point A are (x 1 ,y 1 ), the coordinates of point B are (x 2 ,y 2), the coordinates of point T are (x, y), to determine whether point T is in the rectangle formed by points A and B, we need to check whether it satisfies: Max(x 1 , x 2 )>x>Min(x 1 , x 2 ) and Max(y 1 ,y 2 )>y>Min(y 1 ,y 2 ).

[0064] Step S204: if it exists, determine whether the second monitoring point is a joint alarm based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system.

[0065] Taking the judgment of whether point A and point B in the second monitoring point are joint alarms as an example, after the point judgment in step S203, it is obtained that there are one or more points in the third monitoring point in the point rectangle composed of point A and point B. Because the distance between the two monitoring points of point A and point B is less than the preset distance threshold, the distance meets the joint alarm point. However, since there is a third monitoring point in the point rectangle composed of the two points where no alarm has occurred, from the distance perspective, the third monitoring point located in the middle of the point rectangle composed of point A and point B should also be a joint alarm with point A and point B. However, at this time, no alarm has occurred at the third monitoring point. Therefore, it is necessary to combine the dominant wind direction at that time to determine whether point A and point B are truly joint alarms.

[0066] In some application embodiments, reference Figure 4 Based on the dominant wind direction and the coordinate vector of the second monitoring point in the preset coordinate system, the following method is used to determine whether the second monitoring point is a joint alarm:

[0067] Step B1, obtaining the dominant wind direction within a preset time.

[0068] Because the alarm at the second monitoring point occurs within the preset time, the dominant wind direction θ wind It should also be the dominant wind direction at a preset time point. In the embodiment of the present application, the dominant wind direction θ wind It is obtained by relying on the wind direction sensor at the midpoint of the park or by fluid simulation.

[0069] Step B2: determining the coordinate vector of every two monitoring points in the second monitoring points based on a preset coordinate system.

[0070] Similar to the determination of whether there is a third monitoring point between every two monitoring points in the second monitoring points in step S203, here, based on the preset coordinate system, the coordinate vector between every two points in the second monitoring points is determined. Taking the two monitoring points A and B in the second monitoring points as an example, the coordinate vector is

[0071] Step B3, calculating the angle between the dominant wind direction and the coordinate vector.

[0072] Calculating vectors and the dominant wind direction θ wind The angle Δθ is obtained by calculating the vector of each two monitoring points in the second monitoring point and the dominant wind direction θ. wind Angle.

[0073] Step B4, judging whether the second monitoring point is a joint alarm according to whether the absolute value of the angle is less than or equal to a preset angle threshold.

[0074] Then determine whether the absolute value of Δθ obtained in step B3 is less than or equal to the preset angle threshold. In the embodiment of the present application, the preset angle threshold is preferably 5 degrees. If the absolute value of Δθ is less than or equal to the preset angle threshold, it can be determined that the two monitoring points corresponding to Δθ are joint alarms. If the absolute value of Δθ is greater than the preset angle threshold, it is determined that the two monitoring points corresponding to Δθ are independent alarms. After judging all Δθ, it can be determined which of the second monitoring points are independent alarms. Because this application only determines whether every two monitoring points are joint alarms, which points are joint alarms are determined based on the correlation between each monitoring point. In an example, through the above judgment, point A is a joint alarm with point B and point C respectively, then it can be determined that point A, point B and point C are joint alarms.

[0075] In some application embodiments, if there is no monitoring point between the second monitoring points where no alarm occurs, the second monitoring point is determined to be a joint alarm.

[0076] If there are two monitoring points in the second monitoring points without a third monitoring point between them, the two monitoring points can be directly determined as joint alarms. Combined with the joint alarm monitoring points determined in step S204, the monitoring points in the second monitoring points that are independent alarms and the monitoring points that are joint alarms are obtained.

[0077] Through the above steps, the independent alarm monitoring points and the joint alarm monitoring points in the first monitoring point where the alarm occurs at the preset time can be determined. The alarm identification of the present application is more conducive to the subsequent tracing of the leakage source of the alarm event.
