[0066] According to the solution of the present invention, the server will determine the planning area around the river channel and obtain the planning elements in the planning area. Since each planning element may only occupy part of the planning area, the server will determine the element sub-areas occupied by the planning elements corresponding to different element types in the planning area. In addition, there may be a situation where the distribution between the element sub-areas is relatively dense. In order to facilitate the subsequent monitoring, the server will merge the element sub-areas with regional joint relationships along the extension direction of the river channel, so as to obtain the updated element sub-areas, which can reduce the configuration of subsequent monitoring equipment and thus reduce the corresponding cost. Then, the server will extract features from each element sub-area. After obtaining each feature data, the server will configure the monitoring unit for regional monitoring of each element sub-area according to the feature data, and control all monitoring units to perform real-time regional monitoring on each element sub-area, so as to timely configure the strategies of various intervention strategies according to the acquired real-time monitoring data, which can improve the monitoring efficiency to a certain extent.

[0071] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0072] Reasonable planning of rivers can not only prevent soil erosion and improve the ecological environment, but also improve the urban landscape, provide citizens with places for leisure, walking and other activities, and improve people's quality of life.

[0073] The existing monitoring method for river planning areas is to set up monitoring equipment beside the river, which requires manual review of the monitoring images. This not only wastes a certain amount of manpower and costs, but may also miss emergency situations due to negligence, causing corresponding impacts.

[0074] In order to solve the problems existing in the above-mentioned prior art, an embodiment of the present invention provides a design method for multi-dimensional attribute reference in the process of river construction. The method can be executed in a computing device, wherein the computing device can be understood as a terminal with data processing function, such as a mobile phone or a computer.

[0075] Figure 1 A flow chart of a method for designing a multi-dimensional attribute reference in a river channel construction process according to an embodiment of the present invention is shown, and the method is suitable for execution in a computing device.

[0076] like Figure 1 As shown, the purpose of this embodiment is to implement a design method for multi-dimensional attribute reference in the process of river channel construction, starting from step S102, in which the following contents are included:

[0077] A planning area located around a river channel is determined, and planning elements each corresponding to at least one element type located in the planning area are acquired.

[0078] For example, in this embodiment, the server will first determine the planning area located around the river, for example, the planning area can be a trail area for pedestrians, a vegetation area for planting vegetation, an equipment area for building equipment such as base stations, etc. Then, the server will obtain planning elements located in the planning area that correspond to at least one element type.

[0079] Furthermore, the above-mentioned “determining the planning area around the river” also includes the following steps:

[0080] Acquire a top view corresponding to the river channel, and determine an extension length corresponding to the river channel;

[0081] Dividing the river channel into points based on the extension length and along the extension direction of the river channel to obtain each river channel point;

[0082] Establishing vertical lines passing through each point of the river in a direction perpendicular to the extension direction of the river, and acquiring vertical pixel points constituting the vertical line of the same point based on the top view;

[0083] Perform pixel value difference calculations on each vertical pixel point that constitutes a vertical line at the same point and is located at adjacent positions to obtain each pixel difference, and divide two vertical pixel points whose corresponding pixel difference is less than or equal to a preset first value into the same pixel group to obtain each pixel group corresponding to the vertical line at the same point;

[0084] Determine the first end pixel point and the second end pixel point corresponding to different ends in the same pixel group in a direction perpendicular to the extending direction of the river channel, and arrange the end pixel points in sequence along the direction perpendicular to the extending direction of the river channel to obtain pixel sequences corresponding to vertical lines at each point position;

[0085] The end pixel points corresponding to the same pixel number in each pixel sequence are point-connected to obtain each division line segment, and the area composed of each division line segment located at adjacent positions is determined as a division sub-area to obtain a planning area composed of each division sub-area.

[0086] For example, in this embodiment, the server first obtains a top view of the river channel and determines the length of the river channel, that is, the extension length, and then divides the river channel into points according to the extension length of the river channel in the extension direction of the river channel, thereby obtaining various river channel points.

[0087] Next, the server will establish vertical lines passing through each point in the river channel in a direction perpendicular to the extension direction of the river channel, and then obtain the vertical pixel points that make up the same vertical line through the top view, and perform difference calculations on the pixel values ​​of each vertical pixel point that makes up the same vertical line and is located at adjacent positions, thereby obtaining the pixel difference.

[0088] A preset first value is preset in the server. When the pixel difference is less than or equal to the preset first value, it means that the difference in pixel values ​​between the two vertical pixel points is not large. Therefore, the server will divide the two vertical pixel points whose corresponding pixel difference is less than or equal to the preset first value into the same pixel group, thereby obtaining pixel groups corresponding to the vertical lines at the same point.

[0089] Next, the server will determine the pixel points at the two ends of the same pixel group in a direction perpendicular to the extension direction of the river channel, namely the first end pixel point and the second end pixel point, and arrange the end pixel points in sequence along the direction perpendicular to the extension direction of the river channel, thereby obtaining pixel sequences corresponding to the vertical lines of each point position.

[0090] At this time, the server will connect the end pixels corresponding to the same pixel number in each pixel sequence, for example, connect the end pixel at the first position in each pixel sequence, so as to obtain each division line segment. Then, the server will determine the area composed of each division line segment at adjacent positions as a division sub-area, so as to obtain a planning area composed of each division sub-area.

[0091] This embodiment can determine the planned area around the river channel by taking advantage of the dimension that the pixel values ​​of different divided sub-areas are different, with a certain degree of accuracy.

[0092] Furthermore, the above method further comprises the following steps:

[0093] Acquire a center point of a corresponding river channel based on the upper view, and establish a center line of the river channel passing through the center point of the river channel along an extension direction of the river channel;

[0094] Determine the distances between each channel point and the centerline of the channel, and perform a difference calculation based on the point distances on each channel point located at adjacent positions to obtain each distance difference;

[0095] In response to any distance difference being greater than a preset second value, the distance difference is multiplied by a preset increase coefficient, and the obtained product result is integerized to obtain the number of points added;

[0096] Points are added between two river points corresponding to the distance difference based on the number of points added to obtain newly added river points.

[0097] For example, in this embodiment, since the river channel may not be straight but has certain bends, this will cause a certain height difference between the end pixel points corresponding to the same pixel number in different pixel sequences. In order to avoid affecting subsequent steps, the server will further add river channel points.

[0098] First, the server will obtain the center point of the river channel according to the top view, and establish a river centerline passing through the center point of the river channel along the extension direction of the river channel, and then determine the distance between each river channel point and the river channel centerline, that is, the distance between each point, and calculate the interval distance between each river channel point at adjacent positions, that is, perform a difference calculation based on the point distance, and obtain each distance difference.

[0099] A preset second value is preset in the server in advance. When any distance difference is greater than the preset second value, it means that the height difference between the two river points corresponding to the distance difference is large. Therefore, the server will multiply the distance difference with the preset increase coefficient and integerize the obtained product result to obtain the number of points added. At this time, the server will increase the number of points between the two river points corresponding to the distance difference according to the number of points added, thereby obtaining the newly added river points.

[0100] This embodiment can determine whether there is an area with a large degree of curvature in the river channel by calculating the distance differences, thereby adding points in the area with a large degree of curvature, so that the height difference of each added river channel point is smaller, which facilitates improving the corresponding accuracy of the server in determining each planning area.

[0101] Furthermore, the above-mentioned “obtaining planning elements corresponding to at least one element type in the planning area” further includes the following steps:

[0102] Determine the number of regions corresponding to each divided sub-region of the planned area, and perform the same number of image replications on the top view based on the number of regions to obtain replicated images;

[0103] Establishing image association relationships between each replicated image and different divided sub-regions respectively, and performing blank processing on sub-regions other than the divided sub-regions with which the replicated image has image association relationships, to obtain processed images corresponding to the divided sub-regions respectively;

[0104] Each processed image is input into a trained image recognition model to obtain planning elements corresponding to at least one element type located in each processed image.

[0105] For example, in this embodiment, the server will first determine the number of sub-areas divided in the planned area, and copy the same number of images of the upper view according to the number of areas, thereby obtaining each copied image. For example, if the number of sub-areas divided is 3, the server will copy the upper view into 3 copies, thereby obtaining 3 copied images.

[0106] Then, the server will establish image association relationships between each copy image and different sub-regions, that is, each copy image has an image association relationship with a sub-region. Next, the server will blank out the sub-regions in each copy image except for the sub-regions with which it has an image association relationship, and obtain processed images corresponding to each sub-region, that is, only one sub-region will be displayed in each processed image, and the area positions of the other sub-regions will be blank, so that after the server inputs each processed image into the trained image recognition model, it can obtain the planning elements corresponding to at least one element type in each processed image, and can also improve the recognition accuracy.

[0107] In step S104, the following contents are included:

[0108] The element sub-regions respectively occupied by the planning elements corresponding to different element types in the planning area are determined, and the element sub-regions having a regional joint relationship with each other are merged along the extension direction of the river channel to obtain updated element sub-regions.

[0109] For example, in this embodiment, since the planning elements corresponding to different element types in the planning area may not occupy the entire area of ​​the planning area, for example, only a small number of devices may be placed, and a certain distance may be left between each device, the area occupied by each device can be understood as an element sub-area, that is, the server will determine the element sub-areas occupied by each planning element corresponding to different element types in the planning area.

[0110] Since the element sub-regions may be densely distributed, in order to facilitate the subsequent server monitoring, the server will merge the element sub-regions that are close to each other along the extension direction of the river, that is, merge the element sub-regions with regional joint relationships, so as to obtain updated element sub-regions.

[0111] This embodiment can merge the element sub-regions that have a regional joint relationship with each other along the extension direction of the river channel, so that when the updated element sub-regions are subsequently monitored, the setting of certain monitoring equipment can be reduced, thereby improving the corresponding monitoring efficiency and reducing certain costs.

[0112] Furthermore, the above-mentioned "determining the element sub-areas occupied by the planning elements corresponding to different element types in the planning area, and merging the element sub-areas having a regional joint relationship with each other along the extension direction of the river channel to obtain updated element sub-areas" also includes the following steps:

[0113] Establishing an image coordinate system corresponding to the top view, wherein an X-axis of the image coordinate system is parallel to the centerline of the river channel;

[0114] Based on the image coordinate system, each element coordinate group constituting each planning element is obtained, and an X-axis coordinate point and a Y-axis coordinate point corresponding to an X-axis extreme value and a Y-axis extreme value respectively located in the same element coordinate group are determined;

[0115] Generate a planning outline surrounding the planning element based on the X-axis coordinate points and the Y-axis coordinate points located in the same element coordinate group, and determine the area located in the planning outline as the initial sub-area corresponding to the planning element, to obtain initial sub-areas corresponding to each planning element;

[0116] Expanding each initial sub-region based on a preset coefficient, and determining each initial sub-region after the expansion as each element sub-region corresponding to each planning element;

[0117] Based on the horizontal joint strategy, each element sub-region is determined based on the horizontal joint region, and each element sub-region that has a horizontal joint relationship with each other is divided into the same preliminary screening group, so as to obtain preliminary screening groups corresponding to different horizontal joint relationships;

[0118] Based on the vertical union strategy, each element sub-region in the same preliminary screening group is determined based on the vertical union region, and each element sub-region having a vertical union relationship with each other is merged to obtain updated element sub-regions.

[0119] For example, in this embodiment, the server will establish an image coordinate system corresponding to the upper view, and the X axis of the image coordinate system is parallel to the center line of the river channel. The server will obtain the element coordinate groups that constitute each planning element according to the image coordinate system, and determine the X axis coordinate point corresponding to the X axis extreme value and the Y axis coordinate point corresponding to the Y axis extreme value in the same element coordinate group.

[0120] The server generates a planning outline surrounding the planning element according to the X-axis coordinate points and the Y-axis coordinate points in the same element coordinate group, and determines the area in the planning outline as the initial sub-area corresponding to the planning element, thereby obtaining initial sub-areas corresponding to each planning element.

[0121] Since each initial sub-region obtained by the above method is obtained based on the planning outline generated by the X-axis coordinate point and the Y-axis coordinate point in the same element coordinate group, that is, each initial sub-region is closely fitted with the edge of each planning element, the server will expand each initial sub-region according to the preset coefficient, so that each initial sub-region after the expansion can be larger than the outer contour of each planning element. If part of the area of ​​each initial sub-region after the expansion is located outside the divided sub-region, the server will intercept each initial sub-region after the expansion according to the area contour of the divided sub-region, so as to obtain each element sub-region corresponding to each planning element within the divided sub-region.

[0122] Next, the server will determine the regions of each element sub-region based on the horizontal joint strategy, and divide the element sub-regions that have a horizontal joint relationship with each other into the same preliminary screening group, thereby obtaining preliminary screening groups corresponding to different horizontal joint relationships. Then, based on the vertical joint strategy, the server will determine the regions of each element sub-region in the same preliminary screening group based on the vertical joint strategy, and merge the element sub-regions that have a vertical joint relationship with each other, thereby obtaining updated element sub-regions.

[0123] Furthermore, the above-mentioned "determining the regions of each element sub-region based on the horizontal joint strategy, and dividing the element sub-regions having a horizontal joint relationship with each other into the same preliminary screening group, to obtain preliminary screening groups corresponding to different horizontal joint relationships", further includes the following steps:

[0124] Mapping each element sub-region to the center line of the river channel along a direction perpendicular to the center line of the river channel to obtain each lateral mapping line corresponding to each element sub-region.

[0125] Determine whether there is an overlapping relationship between the horizontal mapping lines, and divide the element sub-regions respectively corresponding to the horizontal mapping lines with overlapping relationships into the same preliminary screening group, and divide the element sub-regions respectively corresponding to the horizontal mapping lines without overlapping relationships into different preliminary screening groups, to obtain preliminary screening groups;

[0126] Merging the horizontal mapping lines corresponding to the element sub-regions in the same initial screening group to obtain updated horizontal mapping lines;

[0127] The line segment distances between adjacent transverse mapping lines are determined, and the initial screening groups corresponding to the transverse mapping lines whose corresponding line segment distances are less than or equal to the third preset value are merged to obtain updated preliminary screening groups.

[0128] For example, in this embodiment, the server will map each element sub-area onto the center line of the river along a direction perpendicular to the center line of the river, thereby obtaining each lateral mapping line corresponding to each element sub-area, such as Figure 2 As shown, the four element sub-areas are mapped onto the center line of the river channel respectively, thereby obtaining the corresponding lateral mapping lines.

[0129] Next, the server will determine whether there is an overlapping relationship between the horizontal mapping lines, and divide the element sub-areas corresponding to the horizontal mapping lines with overlapping relationships into the same preliminary screening group, and divide the element sub-areas corresponding to the horizontal mapping lines without overlapping relationships into different preliminary screening groups, thereby obtaining preliminary screening groups.

[0130] At this time, the server will merge the line segments of each horizontal mapping line corresponding to each element sub-region in the same initial screening group, so as to obtain an updated horizontal mapping line. Then, the line segment distance between each horizontal mapping line located at an adjacent position is determined. When the line segment distance is less than or equal to the third preset value, it means that the line segment distance of the two horizontal mapping lines is close. Therefore, the server will merge the initial screening groups corresponding to each horizontal mapping line whose corresponding line segment distance is less than or equal to the third preset value, so as to obtain updated preliminary screening groups.

[0131] Furthermore, the above-mentioned “determining the regions of each element sub-region in the same preliminary screening group based on the vertical union strategy, and merging the element sub-regions having a vertical union relationship with each other to obtain updated element sub-regions” also includes the following steps:

[0132] Generating a vertical line of the river channel along a direction perpendicular to the center line of the river channel, and dividing the vertical line of the river channel into segments based on each divided sub-area to obtain each vertical sub-segment;

[0133] Mapping each element sub-region in the same preliminary screening group to the vertical line of the river channel along a direction perpendicular to the vertical line of the river channel, respectively, to obtain each vertical mapping line corresponding to each element sub-region;

[0134] Determine the positional relationship between each vertical mapping line and each vertical sub-line segment, and merge each vertical mapping line located in the same vertical sub-line segment and / or each vertical sub-line segment located between adjacent positions to obtain updated vertical mapping lines;

[0135] The preliminary screening groups are split based on each vertical mapping line to obtain updated preliminary screening groups corresponding to each vertical mapping line;

[0136] Each element sub-region located in the same preliminary screening group is merged to obtain updated element sub-regions.

[0137] For example, in this embodiment, the server generates a vertical line of the river along the direction perpendicular to the center line of the river, and divides the vertical line of the river into segments according to each divided sub-area, thereby obtaining each vertical sub-segment. Then, each element sub-area in the same preliminary screening group is mapped onto the vertical line of the river along the direction perpendicular to the vertical line of the river, thereby obtaining each vertical mapping line corresponding to each element sub-area, such as Figure 3 As shown, the four element sub-areas are mapped onto the vertical lines of the river channel respectively, thereby obtaining corresponding vertical mapping lines.

[0138] The server determines the positional relationship between each vertical mapping line and each vertical sub-line segment, and merges each vertical mapping line located in the same vertical sub-line segment and / or each vertical sub-line segment located between adjacent positions, thereby obtaining updated vertical mapping lines.

[0139] Next, the server will split the preliminary screening groups according to the vertical mapping lines, thereby obtaining updated preliminary screening groups corresponding to the vertical mapping lines, and then merge the element sub-regions in the same preliminary screening group, thereby obtaining updated element sub-regions.

[0140] This embodiment further determines the vertical joint relationship of each element sub-region, thereby obtaining updated element sub-regions to facilitate subsequent corresponding monitoring thereof.

[0141] In step S106, the following contents are included:

[0142] Features are extracted for each element sub-region, and monitoring configuration of monitoring units for performing regional monitoring on each element sub-region is performed based on the obtained feature data.

[0143] For example, in this embodiment, the server will extract features from each element sub-region, such as obtaining the area size of the element sub-region, etc., so as to obtain various feature data, and then configure the monitoring unit for regional monitoring of each element sub-region according to the feature data, that is, configure the monitoring camera.

[0144] Furthermore, the above-mentioned “extracting features from each element sub-region, and performing monitoring configuration of a monitoring unit for performing regional monitoring on each element sub-region based on the obtained feature data” further includes the following steps:

[0145] Extracting features from each element sub-region to determine the number of regions of the divided sub-regions occupied by each element sub-region and the lateral size corresponding to the extension direction of the river channel;

[0146] Calculate the ratio of the horizontal dimension to the preset monitoring dimension, and multiply the obtained dimension ratio by the number of regions to obtain the monitoring number;

[0147] A monitoring configuration is performed on each element sub-area with a number of monitoring units that is the same as the monitoring number.

[0148] For example, in this embodiment, the server will extract features from each element sub-region, so as to determine the number of areas of the divided sub-regions occupied by each element sub-region. For example, when part of an element sub-region is located in one divided sub-region and the rest of the area is located in another divided sub-region, the number of areas of the divided sub-regions occupied by the element sub-region is 2. In addition, the server will also determine the lateral size of each element sub-region corresponding to the extension direction of the river channel.

[0149] The server has a preset second value preset in advance, and the server will calculate the ratio of the horizontal size to the preset monitoring size to obtain the size ratio, and then multiply the size ratio by the number of regions to obtain the monitoring number. At this time, the server will configure each element sub-region with the same number of monitoring units as the monitoring number. For example, if the monitoring number is 3, the server will configure 3 monitoring units for the element sub-region.

[0150] This embodiment can determine the number of monitoring units that need to be configured according to the number of areas of the divided sub-areas occupied by each element sub-area and the lateral size corresponding to the extension direction of the river channel, thereby ensuring the integrity of the monitoring area.

[0151] In step S108, the following contents are included:

[0152] All monitoring units are controlled to perform real-time regional monitoring of each element sub-area, and different intervention strategies are configured based on the acquired real-time monitoring data.

[0153] For example, in this embodiment, the server controls all monitoring units to perform real-time regional monitoring of each element sub-area respectively, so as to configure different intervention strategies according to the real-time monitoring data obtained, so that when there are similar situations such as pedestrians in the equipment area, corresponding intervention can be carried out in time.

[0154] Furthermore, the aforementioned “the element types include vegetation types, pedestrian types, and equipment types;

[0155] Control all monitoring units to perform real-time regional monitoring on each element sub-region respectively, and configure different intervention strategies based on the acquired real-time monitoring data", and also include the following steps:

[0156] Acquire the regional attributes corresponding to each divided sub-region, and control all monitoring units to perform real-time regional monitoring on each element sub-region, wherein the regional attributes include passage attributes and restricted access attributes;

[0157] Determine the divided sub-areas where the planning elements corresponding to the vegetation types are located;

[0158] When the area attribute of the divided sub-area is a pass attribute, a vegetation clearing signal is sent to the vegetation management terminal;

[0159] When the area attribute of the divided sub-area is a no-entry attribute, performing morphological acquisition on the planning element, determining a vegetation state corresponding to the planning element, and sending a vegetation management signal carrying the vegetation state to the vegetation management terminal when the vegetation state is an abnormal state;

[0160] and / or,

[0161] Determine a planning sub-area where a planning element corresponding to the pedestrian type is located;

[0162] When the area attribute of the planned sub-area is a no-entry attribute, controlling a broadcast unit arranged in the river to play a reminder voice;

[0163] and / or,

[0164] Determine a planning sub-area where a planning element corresponding to the equipment type is located;

[0165] When the area attribute of the planned sub-area is a traffic attribute, sending a device check signal to the device management terminal;

[0166] When the area attribute of the planned sub-area is a restricted attribute, the planning element is morphologically acquired, the device status corresponding to the planning element is determined, and when the device status is an abnormal state, a device management signal carrying the device status is sent to the device management terminal.

[0167] For example, in this embodiment, the element types include vegetation types, pedestrian types, and equipment types. The server will obtain the area attributes corresponding to each divided sub-area, and the area attributes include the passage attributes that allow pedestrians to pass and the restricted attributes that do not allow pedestrians to pass. The server will control all monitoring units to perform real-time area monitoring on each element sub-area.

[0168] The server will determine the divided sub-area where the planning element of the corresponding vegetation type is located. When the area attribute of the divided sub-area is the access attribute, it means that vegetation has grown into the trail area, which may cause certain obstacles to the passage of pedestrians. Therefore, the server will send a vegetation cleaning signal to the vegetation management end, so that the vegetation management end can trim the vegetation growing into the trail area accordingly; when the area attribute of the divided sub-area is the restricted attribute, the server will obtain the morphology of the planning element to determine the vegetation status corresponding to the planning element. When the vegetation status is abnormal, the vegetation may be tilted or withered. Therefore, the server will send a vegetation management signal carrying the vegetation status to the vegetation management end, so that the vegetation management end can understand the vegetation status in a timely manner and quickly make corresponding processing.

[0169] The server will also determine the planning sub-area where the planning elements corresponding to the pedestrian type are located. When the area attribute of the planning sub-area is a restricted area attribute, it means that a pedestrian has walked into a prohibited equipment area or vegetation area. At this time, the server will control the broadcasting unit installed in the river to play a reminder voice to allow the pedestrian to return to the trail area for walking.

[0170] The server will also determine the planning sub-area where the planning element of the corresponding equipment type is located. When the area attribute of the planning sub-area is a traffic attribute, it is possible that the workers have forgotten the equipment in the trail area. At this time, the server will send a device check signal to the equipment management end, so that the equipment management end can take timely action; when the area attribute of the planning sub-area is a restricted attribute, the server will perform morphological acquisition on the planning element to determine the equipment status of the planning element, and send a device management signal carrying the equipment status to the equipment management end when the equipment status is abnormal, so that the equipment management end can check the equipment status in a timely manner.

[0171] This embodiment can make corresponding interventions by judging the regional attributes of the divided sub-areas where the planning elements corresponding to different element types are located, so that the vegetation management end and the equipment management end can timely understand the vegetation status and the equipment status and make corresponding processing, and can also ensure the safety of pedestrians.

[0172] According to the solution of the present invention, the server will determine the planning area around the river channel and obtain the planning elements in the planning area. Since each planning element may only occupy part of the planning area, the server will determine the element sub-areas occupied by the planning elements corresponding to different element types in the planning area. In addition, there may be a situation where the distribution between the element sub-areas is relatively dense. In order to facilitate the subsequent monitoring, the server will merge the element sub-areas with regional joint relationships along the extension direction of the river channel, so as to obtain the updated element sub-areas, which can reduce the configuration of subsequent monitoring equipment and thus reduce the corresponding cost. Then, the server will extract features from each element sub-area. After obtaining each feature data, the server will configure the monitoring unit for regional monitoring of each element sub-area according to the feature data, and control all monitoring units to perform real-time regional monitoring on each element sub-area, so as to timely configure the strategies of various intervention strategies according to the acquired real-time monitoring data, which can improve the monitoring efficiency to a certain extent.
