[0042] In order to make the technical solutions in the present application or prior art clearer, the accompanying drawings needed in the embodiments or prior art description will be briefly introduced. Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and all other embodiments obtained by a person of ordinary skill in the art without creative work based on the accompanying drawings also belong to the protection scope of the present application.

[0043] Figure 1 is a flowchart of a gas monitoring method provided by an embodiment of the present application. Referring to Figure 1 , the present application provides a gas leakage monitoring method, which can specifically include the following steps:

[0044] Step 101, a three-dimensional model of a to-be-monitored room provided with a gas pipeline is established; the to-be-monitored room is provided with a sound image device.

[0045] In actual application, a gas pipeline is usually arranged in the room for transporting gas, and the gas transported in the gas pipeline can be different in different application scenarios. The embodiments of the present application can monitor whether each type of gas transported in the gas pipeline leaks. For example, in a natural gas central heating scenario, a plurality of gas pipelines can be arranged in the room to transport natural gas to each owner's residence, and whether the natural gas leaks can be monitored. For another example, in a central air conditioning refrigeration scenario, a plurality of gas pipelines can be arranged in the room to transport cold air to each room, and whether the cold air leaks can be monitored. For another example, in an industrial scenario of processing and production, a gas pipeline can be arranged in the room to transport carbon monoxide, nitrogen and other gases to a processing reaction container, and whether the industrial gas leaks can be monitored.

[0046] The acoustic imaging device is placed in the room where the gas leakage needs to be monitored. The room and the gas pipeline arranged in the room can be scanned by a high-precision laser point cloud radar to obtain a spatial point dataset. The room and the gas pipeline in the room are modeled based on the spatial point dataset to obtain a three-dimensional model. In practice, a device with a model number of flukesv600 can be used as the acoustic imaging device.

[0047] In step 102, the coordinate information and the sound pressure value of each monitoring point output by the acoustic imaging device are obtained.

[0048] After the acoustic imaging device in the room is turned on and works, the sound pressure information of the room can be monitored. The acoustic imaging device can output the coordinate information and the sound pressure value of each monitoring point constituting a detection plane. Therefore, the coordinate information and the sound pressure value of each monitoring point constituting a detection plane output by the acoustic imaging device in real time can be obtained. In actual application, if a device with a model number of fluke sv600 is used as the acoustic imaging device, the acoustic imaging device can provide the coordinate information and the sound pressure value of 1728 monitoring points constituting a detection plane each time. The coordinate information can include an X-axis coordinate value, a Y-axis coordinate value and a Z-axis coordinate value. The east direction can be used as the X-axis, the north direction can be used as the Y-axis, and the upward direction can be used as the Z-axis.

[0049] In the embodiments of the present application, after the coordinate information and the sound pressure value of each monitoring point provided by the acoustic imaging device are obtained, whether the gas leaks can be monitored in real time based on the latest sound pressure value data, so as to timely warn the leakage risk and facilitate personnel to check and repair the leakage point online.

[0050] In step 103, the abnormal monitoring point with an abnormal sound pressure value is determined according to the sound pressure value of each monitoring point.

[0051] Specifically, after obtaining the sound pressure value of each monitoring point provided by the sound image device, the sound pressure value of each monitoring point can be compared with a preset sound pressure threshold, so that according to the comparison result, the monitoring point with an abnormal sound pressure value is determined from the plurality of monitoring points.

[0052] The embodiment of the present application can monitor whether various gases leak, and thus different sound pressure thresholds can be set according to different transport gases. For example, if the transport gas is gas A, the sound pressure threshold can be set as a; if the transport gas is gas B, the sound pressure threshold can be set as b.

[0053] In step 104, the abnormal monitoring point is converted into the three-dimensional model according to the coordinate information of the abnormal monitoring point.

[0054] After the abnormal monitoring point with an abnormal sound pressure value is determined, each abnormal monitoring point can be converted into a three-dimensional model according to the coordinate information of each abnormal monitoring point. In the embodiment of the present application, since the sound image device can output the latest coordinate information and sound pressure value data of the monitoring point in real time, the abnormal monitoring points displayed in the three-dimensional model are also dynamically changed in real time. For example, assuming that the abnormal monitoring points determined at the last moment are three points P1, P2 and P3, the three points are converted into the three-dimensional model; assuming that the abnormal monitoring points determined at the next moment are five points P1, P2, P3, P4 and P5, the five points are converted into the three-dimensional model.

[0055] In the embodiment of the present application, by converting the latest abnormal monitoring point into the three-dimensional model, the user can obtain the coordinate information and sound pressure value of the latest abnormal monitoring point in real time through the three-dimensional model, so as to timely check and repair offline.

[0056] In an actual scenario, if a plurality of sound image devices are arranged in a room to be monitored with a similar internal environment, for example, the internal environment of the room to be monitored is a square pattern, and gas pipelines are arranged at four corners, and a sound image device is arranged at each corner for monitoring. At this time, the real-time picture content provided by the sound image device is extremely similar, and the position of the gas leakage cannot be quickly and accurately positioned only through the real-time picture provided by the sound image device. In the embodiment of the present application, by converting the abnormal monitoring point into the three-dimensional model according to the coordinate information of the abnormal monitoring point, the user can obtain the coordinate information of the abnormal monitoring point through the three-dimensional model, so as to quickly and accurately position the position of the gas leakage.

[0057] In step 105, the abnormal monitoring point is prewarned in the three-dimensional model; the prewarning mark is used to prewarn the gas pipeline from leaking.

[0058] Specifically, after each abnormal monitoring point is converted into the three-dimensional model, the maximum abnormal sound pressure value and the minimum abnormal sound pressure value can be determined from the abnormal sound pressure values of each abnormal monitoring point, and the abnormal sound pressure values can be normalized to the range of [0, 255], and finally a warning identification map is generated.

[0059] Figure 2 A warning identification schematic diagram is provided for the embodiment of the present application. Refer to Figure 2 Since the gas leakage occurs near the gas pipeline, the abnormal monitoring points with abnormal sound pressure values are concentrated in a region, the stronger the warning identification is, the greater the sound pressure abnormal value is, and the closer the distance to the leakage point is. In a specific implementation, a red identification can be used for the region range with the maximum sound pressure abnormal value, and a blue identification can be used for the region range with the minimum sound pressure abnormal value.

[0060] In the embodiment of the present application, a three-dimensional model of a to-be-monitored room provided with a gas pipeline can be established, coordinate information and sound pressure values of each monitoring point output by a sound image device arranged in the to-be-monitored room can be acquired, abnormal monitoring points with abnormal sound pressure values can be determined according to the sound pressure values of each monitoring point, the abnormal monitoring points can be converted into the three-dimensional model according to the coordinate information of the abnormal monitoring points, and the abnormal monitoring points can be warning identified in the three-dimensional model, which is used for warning the leakage of the gas pipeline. The embodiment of the present application can timely warn that the gas pipeline of the room currently has a gas leakage abnormality by determining the abnormal monitoring points and warning identifying the abnormal monitoring points in the three-dimensional model, which is beneficial for personnel to timely find the leakage risk; by converting the abnormal monitoring points into the three-dimensional model of the room, a three-dimensional spatial structure view can be obtained, which is beneficial for personnel to quickly locate the position of the leakage point in the room offline and timely make a repair.

[0061] In an optional embodiment, the abnormal monitoring points with abnormal sound pressure values can include: traversing each monitoring point, judging whether the sound pressure value of the currently traversed monitoring point is greater than a preset sound pressure threshold; if the sound pressure value of the currently traversed monitoring point is greater than the preset sound pressure threshold, determining that the currently traversed monitoring point is an abnormal monitoring point with an abnormal sound pressure value.

[0062] In actual application, the three-dimensional model established can include a gas pipeline, since the gas leakage occurs near the gas pipeline, after the gas leakage, the sound will be transmitted to the detection surface of the sound image device, causing the sound pressure values monitored by each monitoring point on the detection surface to be different. By traversing all the monitoring points, judging whether the sound pressure value of each monitoring point is greater than a preset sound pressure threshold, the abnormal monitoring points with abnormal sound pressure values can be determined, and a set of abnormal monitoring points can be obtained.

[0063] In the embodiment of the present application, by setting the sound pressure threshold for gas leakage monitoring, the monitoring point with abnormal sound pressure value can be determined, so that the current gas leakage abnormality of the room can be timely warned.

[0064] In an optional embodiment, the sound image device is connected with a holder; after the three-dimensional model of the room to be monitored provided with the gas pipeline is established, the device model coordinates of the sound image device relative to the origin of the three-dimensional model can be associated, the rotation attitude information of the holder connected with the sound image device can be acquired, and the transformation matrix of the sound image device and the holder can be constructed according to the device model coordinates and the rotation attitude information of the holder.

[0065] Specifically, the sound image device can be connected with a 360° rotating holder, and after the connection, the sound image device can rotate with the holder, so as to monitor the sound pressure information of the room in all directions.

[0066] After the three-dimensional model of the room to be monitored is established, the device model coordinates of the sound image device relative to the origin of the three-dimensional model can be associated, wherein the device model coordinates are used to represent the position coordinates of the sound image device in the three-dimensional model coordinate system. Since the holder can rotate continuously, the rotation attitude of the holder also changes continuously, so in the process of real-time monitoring, the rotation attitude information of the holder connected with the sound image device needs to be acquired in real time, so as to construct the transformation matrix of the sound image device and the holder based on the device model coordinates and the rotation attitude information of the holder.

[0067] In the embodiment of the present application, by constructing the transformation matrix of the sound image device and the holder according to the device model coordinates and the rotation attitude information of the holder, the position of the sound image device in the three-dimensional model can be more accurately located, so as to improve the positioning accuracy of the leakage point.

[0068] In an optional embodiment, the transformation matrix of the sound image device and the holder can be constructed according to the device model coordinates and the rotation attitude information of the holder, which can include: constructing a first transformation matrix of the sound image device according to the device model coordinates; and constructing a second transformation matrix of the sound image device after the rotation of the holder by rotating the first transformation matrix according to the rotation attitude information of the holder.

[0069] The attitude information of the holder can include yaw angle, pitch angle, roll angle and the like. Specifically, first, the device model coordinates of a device relative to the origin of the three-dimensional model of the room can be associated according to different rooms, and the transformation matrix M1 of the sound image device can be constructed according to the device model coordinates; then, the transformation matrix M2 of the sound image device after the rotation of the holder can be constructed by rotating the transformation matrix M1 according to the rotation attitude information of the yaw angle, the pitch angle and the roll angle of the holder.

[0070] In this embodiment of the invention, by using the coordinates of the device model and the rotation attitude information of the pan-tilt unit connected to the audio-visual equipment, the actual offline audio-visual equipment can be intuitively viewed through a three-dimensional model as the pan-tilt unit rotates in a room containing gas pipes.

[0071] In one optional embodiment, the step of transforming the abnormal monitoring point into the three-dimensional model based on the coordinate information of the abnormal monitoring point may include: multiplying the coordinates of the abnormal monitoring point with the second transformation matrix to transform the coordinates of the abnormal monitoring point into the coordinate system of the three-dimensional model.

[0072] Specifically, the coordinate information of the monitoring points output by the audio-visual equipment is relative to the center point of the audio-visual equipment itself. After constructing the transformation matrix M2 after the audio-visual equipment is rotated by the pan-tilt unit, the coordinates of each abnormal monitoring point can be multiplied by the transformation matrix M2, thereby transforming the coordinates of each abnormal monitoring point into the coordinate system of the three-dimensional model.

[0073] In this embodiment of the invention, by multiplying the coordinates of the abnormal monitoring points with the transformation matrix of the audio-visual equipment after rotation by the pan-tilt unit, the coordinates of the abnormal monitoring points are transformed into the coordinate system of the three-dimensional model. All abnormal monitoring points can be transformed into the three-dimensional model, so that the position of each abnormal monitoring point in the room containing gas pipes can be viewed intuitively through the three-dimensional model.

[0074] In an optional embodiment, after marking the abnormal monitoring point in the three-dimensional model with an early warning sign, the method may further include: drawing a ray from the center point of the audio-visual equipment in the three-dimensional model through the abnormal monitoring point; and determining the point where the ray intersects with the three-dimensional model as the gas pipeline leak point.

[0075] After traversing all monitoring points and identifying the set of abnormal monitoring points with abnormal sound pressure values, a ray can be drawn from the center point of the audio-visual equipment, passing through the abnormal monitoring points. This ray will intersect the 3D model at a single point, which is the corresponding gas pipeline leak point. The coordinates of the leak point can be displayed in the 3D model. Since there are multiple abnormal monitoring points, multiple rays can be drawn, each intersecting the 3D model to obtain its corresponding gas pipeline leak point. For example, assuming there are three abnormal monitoring points P1, P2, and P3, a ray L1 can be drawn from the center point of the audio-visual equipment, passing through P1 and intersecting the 3D model at point A; a ray L2 can be drawn from the center point of the audio-visual equipment, passing through P2 and intersecting the 3D model at point B; and a ray L3 can be drawn from the center point of the audio-visual equipment, passing through P3 and intersecting the 3D model at point C. Therefore, the gas pipeline leak points are at points A, B, and C.

[0076] In this embodiment of the invention, by determining the gas pipeline leak point based on the location of the abnormal monitoring point in the three-dimensional model, the problem that current audio-visual equipment can only provide real-time video monitoring and cannot provide spatial information of the actual leak point can be avoided, thereby enabling personnel to quickly locate the leak point offline for repair.

[0077] In this embodiment of the invention, a three-dimensional model of the room to be monitored, containing gas pipelines, can be established. The coordinate information and sound pressure value of each monitoring point output by the audio-visual equipment installed in the room can be obtained. Abnormal monitoring points with abnormal sound pressure values ​​are determined based on the sound pressure values ​​of each monitoring point. Based on the coordinate information of the abnormal monitoring points, these points are converted into the three-dimensional model, and warning markers are added to the three-dimensional model to indicate potential gas pipeline leaks. By identifying abnormal monitoring points and adding warning markers to them in the three-dimensional model, this embodiment of the invention can promptly warn of gas pipeline leaks in the room, facilitating timely detection of leak risks. Furthermore, by converting the abnormal monitoring points into the three-dimensional model of the room, a three-dimensional spatial structure view can be obtained, allowing personnel to quickly locate the leak point within the room and promptly carry out repairs.

Furthermore, by converting the abnormal monitoring points into the three-dimensional model of the room, a three-dimensional spatial structure view can be obtained, allowing personnel to quickly locate the leak point within the room and promptly carry out repairs.
