[0044] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0045] Example 1

[0046] This embodiment provides a monitoring method for an electro-purification component with a wire plate structure. The electro-purification component includes a plurality of filamentous emitters and a plate-shaped collector. Refer to Figure 1 , the monitoring method includes:

[0047] S11. Obtain a first image including the electro-purification component in a discharge state.

[0048] S12. Obtain the corona edge data of the emitter based on the first image.

[0049] S13. Obtain the initial corona edge data corresponding to the initial time point.

[0050] S14. Generate a discharge state monitoring result based on the corona edge data and the first distance range. The discharge state monitoring result is used to indicate whether the emitter is in a normal working state. The first distance range is determined by the distance between the initial corona edge and the axis of the corresponding emitter in the initial corona edge data. The first distance range is used to determine the range of the corona edge in the normal working state.

[0051] Among them, the first image can be captured by an image acquisition device (such as a camera or a webcam). The first image should include all the emitters and collectors in the electro-purification component. The first image reflects the image information of the emitters and collectors along their respective axis directions. Figure 2A The structure diagram of the electro-purification component B0 is shown. The emitter B1 can be a tungsten wire with a diameter not greater than 0.5 mm, and the collector B2 is a metal plate. The emitters B1 and collectors B2 are arranged at intervals. Due to the structure of the electro-purification component B0, after discharge, the emitter B1 is more likely to fail or be damaged relative to the collector B2.

[0052] Refer to Figure 2B , the bracket B3 of the electro-purification component B0 can be installed on the cavity C1 so that the electro-purification component B0 is inside the cavity C1. The opaque cavity C1 provides a darkroom environment for monitoring the electro-purification component B0. A detection window C2 is provided on the cavity C1. The image acquisition device C3 is arranged outside the cavity C1. The image acquisition device C3 captures the first image through the detection window C2. The dashed line in the figure represents the shooting range of the image acquisition device C3. The detection window C2 is provided at the bottom of the cavity C1, and the bottom surface of the cavity C1 forms a preset angle with the horizontal plane. When the electro-purification component B0 is in a discharge state, due to air ionization, the brightness of the air around the emitter B1 will increase and a corona will be generated. The image acquisition device C3 can adopt a suitable working mode according to actual needs, such as a non-infrared fill light working mode. The image acquisition device C3 sends the captured first image to the processor 31.

[0053] The initial time point refers to the time when the electro-purification component needs to be monitored for the first time (i.e., the first time it is in a discharge state). At the initial time point, the data of the discharge state of the electro-purification component at the first use (i.e., the initial corona edge data) is used as the reference for the normal state. Specifically, the first distance range is determined by combining the initial corona edge data with a correction factor. The correction factor can make the first distance range greater than the maximum distance to accommodate the influence of factors such as voltage fluctuations of the electro-purification component. The correction factor can be set according to actual needs.

[0054] The method for obtaining the initial corona edge data is similar to the method for obtaining the corona edge data, which will not be elaborated here.

[0055] If the electro-purification component is replaced, the initial corona edge data of the replaced electro-purification component needs to be obtained as the reference for the normal state of this electro-purification component. If part of the emitter of the electro-purification component is replaced, the initial corona edge data corresponding to the replaced emitter needs to be obtained as the reference for the normal state of this emitter.

[0056] In this embodiment, the monitoring result of the discharge state of the electro-purification component is generated according to the image of the discharge state of the electro-purification component, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, realizing real-time and effective monitoring of the electro-purification component, providing component failure warning and fault location prompt when the electro-purification component is abnormal, improving safety, and enhancing the user experience.

[0057] During specific implementation, refer to Figure 3 , step S12 includes:

[0058] S121. Perform image edge detection on the first image to obtain a second image.

[0059] S122. Traverse the data of the second image along two mutually orthogonal first direction and second direction to obtain corona edge data. Among them, the first direction is parallel to the axis of the emitter.

[0060] Among them, perform image edge detection on the first image T1 to obtain a second image T11, and traverse the image data T11 along the first direction (x-axis) and the second direction (y-axis) respectively to obtain corona edge data. The corona edge data can include the corona edge starting point coordinates of each emitter and the number of pixel points between corona edges, that is, obtain the coordinate positions of the corona edges of each emitter and the shape and size information of the corona.

[0061] In this embodiment, the edge of the corona is identified through image edge detection, and the corona edge starting point coordinates of each emitter and the number of pixel points between corona edges and other corona edge data are obtained through traversal in the first direction and the second direction.

[0062] During specific implementation, the corona edge data includes pixel points on the corona edge of each emitter that reach a preset brightness threshold and the coordinates of the pixel points.

[0063] The initial corona edge data includes initial pixel points on the corona edge of each emitter that reach a preset brightness threshold and the maximum initial distance of the axis corresponding to the distance determined by the initial pixel points of each emitter. The first distance range is determined by the corresponding maximum initial distance.

[0064] Refer to Figure 4 , step S14 includes:

[0065] S141. For each emitter, when the pixel points are all within the first distance range from the corresponding axis, the discharge state monitoring result indicates that the corresponding emitter is in a normal working state.

[0066] In this embodiment, the ionization edge of the emitter in the discharge state is determined by brightness. According to the position of the ionization edge, that is, whether the position of the pixel points on the ionization edge is within the first distance range from the corresponding axis, it is determined whether the corresponding emitter is in a normal working state, and further the risk state of the emitter is determined. Then, corresponding processing is performed according to the risk state, realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault position prompt, improving safety and enhancing the user experience.

[0067] During specific implementation, the discharge state monitoring result includes an abnormal level and the coordinates of the abnormal points.

[0068] Refer to Figure 5 , step S14 further includes:

[0069] S142. For each emitter, when there are pixel points exceeding the first distance range from the corresponding axis, count the number of pixel points exceeding the first distance range, output the abnormal level according to the number and a preset number threshold, and output the coordinates of the pixel points exceeding the first distance range.

[0070] Among them, the more the number of pixel points exceeding the first distance range, the greater the degree of air ionization and the greater the degree of abnormality. A number threshold can be preset in advance to divide the abnormality into two abnormal levels. Or n number thresholds (n is an integer greater than 1) can be set to divide the abnormality into n + 1 abnormal levels.

[0071] The pixel points exceeding the first distance range are the abnormal points. This embodiment can also output the coordinates of the abnormal points to provide a fault position prompt.

[0072] In this embodiment, the ionization edge of the emitter in the discharge state is determined by brightness, the number of pixel points on the ionization edge exceeding the first distance range is counted, the abnormal level is determined according to this number, the risk state of the emitter is further determined, and then corresponding processing is carried out according to the risk state, realizing real-time and effective monitoring of the electro-purification component. When the electro-purification component is abnormal, it can provide component failure warning and fault location prompt, improving safety and enhancing the user experience.

[0073] The following is an example of a method for monitoring an electro-purification component with a wire plate structure.

[0074] Taking Figure 2A and 2B the shown electro-purification component and the layout of monitoring the electro-purification component as an example, an image containing the electro-purification component can be taken by an image acquisition device, and this image reflects the discharge state in the axial direction of the electro-purification component.

[0075] When the electro-purification component is started for the first time, a first initial image P1 containing the electro-purification component in the discharge state is acquired (i.e., taken), the first initial image P1 is subjected to image edge detection to obtain a second initial image P11. The second initial image P11 includes initial pixel points that reach a preset brightness threshold. The data of the second initial image P11 is traversed along two mutually orthogonal first directions (x-axis) and second directions (y-axis) to obtain initial corona edge data. The initial corona edge data is an array P110[n] composed of (A xi , A yi , △A xi , 0), where i represents the serial number of the emitter, A xi represents the x-axis coordinate of the initial pixel point of the corona edge of emitter i, A yi represents the y-axis coordinate of the initial pixel point of the corona edge of emitter i, △A xi represents the maximum initial distance of the corona edge of emitter i mapped to the x-axis, n represents an integer of N - 1 and satisfies i < n, and N represents the number of emitters of the electro-purification component. P110[n] can be stored in an independent data storage area.

[0076] Set the correction coefficient to 2.5, and the first distance range is determined to be 2.5 * △A xi .

[0077] When the electro-purification component is working, the image acquisition device takes a first image T1 containing the electro-purification component in the discharge state at a fixed frequency f, the first image T1 is subjected to image edge detection to obtain a second image T11. The second image T11 includes pixel points that reach a preset brightness threshold. The data of the second image T11 is traversed along two mutually orthogonal first directions (x-axis) and second directions (y-axis) to obtain corona edge data. The corona edge data is (Txi , T yi , △T xi , 0) to form an array T110[n], where i represents the serial number of the emitter, T xi represents the x-axis coordinate of the pixel point at the corona edge of emitter i, T yi represents the y-axis coordinate of the pixel point at the corona edge of emitter i, △T xi represents the maximum distance that the corona edge of emitter i is mapped to the x-axis, n represents an integer where n = N - 1 and satisfies i < n, and N represents the number of emitters of the electrostatic purification component. T110[n] can be stored in an independent data storage area.

[0078] The distance D from the pixel point to the axis of emitter i can be obtained from the x-axis coordinate T xi of the pixel point at the corona edge of emitter i. xi Usually, D xi ≤ 0.5 * △T xi , for simplicity of calculation, 0.5 * △T xi can be used as the maximum value of D xi for calculation.

[0079] Analyze the discharge state of each emitter:

[0080] When the pixel points at the corona edge of emitter i are all within the first distance range from the corresponding axis, that is, D xi < 2.5 * △A xi (when simplifying the calculation, △T xi < 2 * 2.5 * △A xi ), the electrostatic purification component is in a normal working state. Among them, through the correction coefficient, the first distance range is made larger than the maximum distance to accommodate the influence of factors such as voltage fluctuations of the electrostatic purification component.

[0081] When the pixel points at the corona edge of a certain emitter i exceed the first distance range from the corresponding axis, that is, D xi ≥ 2.5 * △A xi (when simplifying the calculation, △T xi ≥ 2 * 2.5 * △A xi ), count the number CNT of pixel points exceeding the first distance range. If CNT < 10 (the quantity threshold is set to 10), local ionization intensification occurs in the electrostatic purification component, and the coordinate information of the abnormal points (pixel points exceeding the first distance range) is output, and the electrostatic purification component needs to be repaired, such as removing burrs on the corresponding emitter or replacing the corresponding emitter.

[0082] When the pixel points at the corona edge of a certain emitter i exceed the first distance range from the corresponding axis, that is, D xi≥2.5*△A xi When (simplified calculation, △T xi ≥2*2.5*△A xi ), count the number of pixels CNT that exceed the first distance range. If CNT ≥ 10 (the number threshold is set to 10), it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component increases, air ionization intensifies, and there is a possibility of ozone exceeding the standard and emitter breakage, posing a risk of electric shock.

[0083] Example 2

[0084] This embodiment provides a monitoring system for an electric purification component of a wire-plate structure. The electric purification component includes a plurality of wire-shaped emitters and plate-shaped receivers. Figure 6 The monitoring system includes: an image acquisition module 1, a corona edge data calculation module 2, an initial data acquisition module 3 and a monitoring result generation module 4.

[0085] The image acquisition module 1 is used to acquire a first image including the electric purification component in a discharge state.

[0086] The corona edge data calculation module 2 is used to obtain the corona edge data of the emitter based on the first image.

[0087] The initial data acquisition module 3 is used to acquire initial corona edge data corresponding to an initial time point.

[0088] The monitoring result generating module 4 is configured to generate a discharge state monitoring result based on the corona edge data and the first distance range, wherein the discharge state monitoring result is used to indicate whether the emitter is in a normal working state, and the first distance range is determined by the distance between the initial corona edge in the initial corona edge data and the axis of the corresponding emitter.

[0089] The first image can be captured by an image acquisition device (such as a camera or a webcam), and the first image should include all emitters and receivers in the electrical purification component. The first image reflects the image information of the emitters and receivers along their respective axis directions. Figure 2A The structure of the electrical purification component B0 is shown. The emitter B1 can be a tungsten wire with a diameter no greater than 0.5 mm, and the receiver B2 is a metal plate. The emitter B1 and receiver B2 are spaced apart. Due to the structure of the electrical purification component B0, the emitter B1 is more susceptible to failure or damage than the receiver B2 after discharge.

[0090] Reference Figure 2B, the bracket B3 of the electric purification component B0 can be installed on the cavity C1 so that the electric purification component B0 is inside the cavity C1. The opaque cavity C1 provides a darkroom environment for monitoring the electric purification component B0. A detection window C2 is provided on the cavity C1. The image acquisition device C3 is arranged outside the cavity C1. The image acquisition device C3 takes a first image through the detection window C2. The dotted line in the figure represents the shooting range of the image acquisition device C3. The detection window C2 is arranged at the bottom of the cavity C1, and the bottom surface of the cavity C1 forms a preset angle with the horizontal plane. When the electric purification component B0 is in the discharge state, due to air ionization, the brightness of the air around the emitter B1 will increase and corona will be generated. The image acquisition device C3 can adopt a suitable working mode according to actual needs, for example, adopt a working mode without infrared supplementary lighting. The image acquisition device C3 sends the taken first image to the processor 31.

[0091] The initial time point refers to the time when the electric purification component to be monitored is first used (i.e., first in the discharge state). At the initial time point, the data of the discharge state of the electric purification component at the first use (i.e., the initial corona edge data) is used as the reference basis for the normal state. Specifically, a first distance range is determined by combining the initial corona edge data with a correction factor. The correction factor can make the first distance range greater than the maximum distance to accommodate the influence of factors such as voltage fluctuations of the electric purification component. The correction factor can be set according to actual needs.

[0092] The method for obtaining the initial corona edge data is similar to the method for obtaining the corona edge data, which will not be elaborated here.

[0093] If the electric purification component is replaced, the initial corona edge data of the replaced electric purification component needs to be obtained to be used as the reference basis for the normal state of this electric purification component. If some emitters of the electric purification component are replaced, the initial corona edge data corresponding to the replaced emitters needs to be obtained to be used as the reference basis for the normal state of this emitter.

[0094] In this embodiment, the discharge state monitoring result of the electric purification component is generated according to the image of the discharge state of the electric purification component, the risk state of the emitter is determined, and then corresponding processing is carried out according to the risk state, realizing real-time and effective monitoring of the electric purification component, providing component failure warning and fault location prompt when the electric purification component is abnormal, improving safety, and enhancing the user experience.

[0095] Specifically in implementation, the corona edge data calculation module 2 includes: an edge detection unit 21 and a traversal unit 22.

[0096] The edge detection unit 21 is used to perform image edge detection on the first image to obtain a second image.

[0097] The traversal unit 22 is used to traverse the data of the second image along the first direction and the second direction that are orthogonal to each other to obtain corona edge data. Among them, the first direction is parallel to the axis of the emitter.

[0098] Among them, the second image T11 is obtained by performing image edge detection on the first image T1, and the corona edge data is obtained by traversing the image data T11 along the first direction (x-axis) and the second direction (y-axis) respectively. The corona edge data may include the corona edge starting point coordinates of each emitter and the number of pixel points between the corona edges, that is, the coordinate positions of the corona edges of each emitter and the shape and size information of the corona are obtained.

[0099] In this embodiment, the edge of the corona is identified by image edge detection, and the corona edge data such as the corona edge starting point coordinates of each emitter and the number of pixel points between the corona edges is obtained by traversing in the first direction and the second direction.

[0100] Specifically, in implementation, the corona edge data includes the pixel points that reach the preset brightness threshold of the corona edge of each emitter and the coordinates of the pixel points.

[0101] The initial corona edge data includes the initial pixel points that reach the preset brightness threshold of the corona edge of each emitter and the maximum initial distance from the axis corresponding to the distance determined by the initial pixel points of each emitter. The first distance range is determined by the corresponding maximum initial distance.

[0102] For each emitter, the monitoring result generation module 4 is specifically configured to generate a discharge state monitoring result when the pixel points are all within the first distance range from the corresponding axis, and the discharge state monitoring result indicates that the corresponding emitter is in a normal working state.

[0103] In this embodiment, the ionization edge of the emitter in the discharge state is determined by brightness, and according to the position of the ionization edge, that is, whether the position of the pixel points on the ionization edge is within the first distance range from the corresponding axis, it is determined whether the corresponding emitter is in a normal working state, and further the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, realizing real-time and effective monitoring of the electro-purification component, providing component failure warning and fault position prompt when the electro-purification component is abnormal, improving safety, and enhancing the user experience.

[0104] Specifically, in implementation, the discharge state monitoring result includes an abnormal level and abnormal point coordinates.

[0105] For each emitter, the monitoring result generation module 4 is further specifically configured to, when there are pixel points exceeding the first distance range corresponding to the axis of the distance, count the number of pixel points exceeding the first distance range, output an abnormal level according to the number and a preset number threshold, and output the coordinates of the pixel points exceeding the first distance range.

[0106] Among them, the more the number of pixel points exceeding the first distance range, the greater the degree of air ionization and the greater the degree of abnormality. A number threshold can be preset in advance to divide the abnormality into two abnormal levels. Or n number thresholds (n is an integer greater than 1) can be set to divide the abnormality into n + 1 abnormal levels.

[0107] The pixel points exceeding the first distance range are abnormal points. This embodiment can also output the coordinates of the abnormal points to provide a fault location hint.

[0108] In this embodiment, the ionization edge of the emitter in the discharge state is determined by brightness, the number of pixel points on the ionization edge exceeding the first distance range is counted, the abnormal level is determined according to this number, the risk state of the emitter is further determined, and then corresponding processing is performed according to the risk state, realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location hint, improving safety and enhancing the user experience.

[0109] The following is an example of a method for monitoring an electric purification component with a wire plate structure.

[0110] Taking Figure 2A and 2B the shown electric purification component and the layout of monitoring the electric purification component as an example, an image containing the electric purification component can be taken by an image acquisition device, and this image reflects the discharge state in the axis direction of the electric purification component.

[0111] When the electric purification component is started for the first time, a first initial image P1 containing the electric purification component in the discharge state is acquired (i.e., taken), the first initial image P1 is subjected to image edge detection to obtain a second initial image P11. The second initial image P11 includes initial pixel points reaching a preset brightness threshold. The data of the second initial image P11 is traversed along the first direction (x-axis) and the second direction (y-axis) that are orthogonal to each other to obtain initial corona edge data. The initial corona edge data is an array P110[n] composed of (A xi , A yi , △A xi , 0), where i represents the serial number of the emitter, A xi represents the x-axis coordinate of the initial pixel point of the corona edge of emitter i, A yi represents the y-axis coordinate of the initial pixel point of the corona edge of emitter i, △Axi represents the maximum initial distance at which the corona edge of emitter i is mapped to the x-axis, n represents N - 1 and is an integer satisfying i < n, and N represents the number of emitters of the electrostatic purification component. P110[n] can be stored in an independent data storage area.

[0112] Set the correction factor to 2.5, and the first distance range is determined to be 2.5 * △A xi .

[0113] When the electrostatic purification component is working, the image acquisition device takes the first image T1 of the electrostatic purification component in the discharge state at a fixed frequency f, performs image edge detection on the first image T1 to obtain the second image T11. The second image T11 includes pixel points that reach a preset brightness threshold. Traverse the data of the second image T11 along the mutually orthogonal first direction (x-axis) and second direction (y-axis) to obtain corona edge data. The corona edge data is an array T110[n] composed of (T xi , T yi , △T xi , 0). Among them, i represents the serial number of the emitter, T xi represents the x-axis coordinate of the pixel point of the corona edge of emitter i, T yi represents the y-axis coordinate of the pixel point of the corona edge of emitter i, △T xi represents the maximum distance at which the corona edge of emitter i is mapped to the x-axis, n represents N - 1 and is an integer satisfying i < n, and N represents the number of emitters of the electrostatic purification component. T110[n] can be stored in an independent data storage area.

[0114] The distance D of the pixel point from the axis of emitter i can be obtained from the x-axis coordinate T xi of the pixel point of the corona edge of emitter i xi . Usually, D xi ≦0.5 * △T xi . For simplicity of calculation, 0.5 * △T xi can be used as the maximum value of D xi for calculation.

[0115] Analyze the discharge state of each emitter:

[0116] When all the pixel points of the corona edge of emitter i are within the first distance range from the corresponding axis, that is, D xi <2.5 * △A xi (when simplifying the calculation, △T xi <2 * 2.5 * △A xi ), the electrostatic purification component is in a normal working state. Among them, the first distance range is made larger than the maximum distance through the correction factor to accommodate the influence of factors such as voltage fluctuations of the electrostatic purification component.

[0117] When the pixel points at the corona edge of a certain emitter i exceed the first distance range from the corresponding axis, i.e., D xi ≥2.5*△A xi When (for simplified calculation, △T xi ≥2*2.5*△A xi When), count the number CNT of pixel points exceeding the first distance range. If CNT < 10 (the quantity threshold is set to 10), local ionization intensification occurs in the electro-purification component, and the coordinate information of the abnormal points (pixel points exceeding the first distance range) is output. It is necessary to repair the electro-purification component, for example, remove the burrs on the corresponding emitter or replace the corresponding emitter.

[0118] When the pixel points at the corona edge of a certain emitter i exceed the first distance range from the corresponding axis, i.e., D xi ≥2.5*△A xi When (for simplified calculation, △T xi ≥2*2.5*△A xi When), count the number CNT of pixel points exceeding the first distance range. If CNT ≥ 10 (the quantity threshold is set to 10), it is recommended to replace the electro-purification component. There is an increase in the curvature of some emitters in the electro-purification component, intensification of air ionization, the possibility of ozone exceeding the standard and emitter breakage, and there is an electric shock risk.
