Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to an ecological geological analysis and processing method and system based on remote sensing technology. Background Art

[0002] With global climate change and increasing human activities, the frequency and scale of geological disasters such as landslides, mudslides, and ground collapses are increasing. These disasters have had a serious impact on human society and the natural environment. Against this background, the importance of slope protection has become increasingly prominent.

[0003] At present, due to the complex and changeable geological structure of the slope and the continuous influence of natural factors such as rainfall, the risk of slope collapse has increased significantly. However, there are obvious deficiencies in the existing technology in monitoring slope collapse. Protection is often carried out only after the slope has collapsed or there are obvious signs of collapse. For example, after the slope collapses, concrete or mortar is sprayed on the slope surface to form a protective layer. However, due to the influence of environmental factors such as rain erosion and temperature changes, the protective layer may fall off, resulting in unsatisfactory protection effect, thereby reducing the safety of the slope.

[0004] Therefore, how to timely monitor the collapse risk of the slope based on the actual situation of the slope and ensure the stability and safety of the slope has become an urgent problem to be solved. Summary of the Invention

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0069] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0070] See also Figure 1 , is a schematic diagram of an ecological geological analysis and processing method based on remote sensing technology provided by an embodiment of the present invention, Figure 1 The execution subject of the method shown may be a software and / or hardware device. The execution subject of the present application may include but is not limited to at least one of the following: user equipment, network equipment, etc. Among them, user equipment may include but is not limited to computers, smart phones, personal digital assistants (PDAs) and the electronic devices mentioned above. Network equipment may include but is not limited to a single network server, a server group consisting of multiple network servers, or a cloud based on cloud computing consisting of a large number of computers or network servers, wherein cloud computing is a type of distributed computing, a super virtual computer composed of a group of loosely coupled computers. This embodiment does not limit this. It includes steps S1 to S4, as follows:

[0071] S1, obtaining a remote sensing image of a protection destination, and performing geological analysis on the remote sensing image according to a geological analysis model to obtain a risk area.

[0072] Among them, the protection destination refers to the place that needs to be protected from geological disasters, such as the slope next to the highway. The remote sensing image refers to the image corresponding to the slope surface obtained by remote sensing technology such as satellite remote sensing and aerial photography. The geological analysis model refers to a pre-trained model that can analyze remote sensing images. When performing geological analysis, the acquired remote sensing image can be input into the pre-trained geological analysis model. The geological analysis model can output the slope, height and other parameters corresponding to the slope, so that it can be judged whether there is a risk of collapse in the slope area based on these parameters. The risk area refers to the area where there may be a risk of collapse.

[0073] It is understandable that slope collapse is a manifestation of natural disasters, and its occurrence is often related to multiple factors such as geological structure and rainfall. Slope collapse not only poses a threat to people's lives and property, but also causes damage to transportation infrastructure. For example, falling rocks due to collapse may destroy roads, bridges, and other transportation facilities, resulting in traffic interruption. By taking effective protective measures to protect the slopes, such as setting up slope protection nets, the risk and loss of slope collapse can be significantly reduced.

[0074] This solution can determine the type of slope protection net and its corresponding configuration data based on the geological information of the slope, and can use different types of slope protection nets to reinforce and protect the slope in different ways, thereby reducing the risk of slope collapse and improving the safety of the slope. In addition, this solution can conduct regular inspections of the slope area to be protected, check the condition of the protection net and the rockfall situation, so that when the protection net is deformed or there are too many accumulated stones, it can be cleaned and repaired in time to ensure the effectiveness of the protection net and the stability of the slope.

[0075] Specifically, remote sensing technology, such as aerial photography, can be used to obtain remote sensing images corresponding to the destination where slope protection is required. By performing geological analysis on the remote sensing images using a pre-trained geological analysis model, the area corresponding to the slope in the protection destination, as well as data such as the height and slope of the area, can be analyzed from the remote sensing images. With these data, it can be determined whether there is a risk of collapse of the slope in the protection destination. If there is a risk of collapse, the area corresponding to the slope with the risk of collapse can be identified as a risk area, and the risk area can be protected subsequently.

[0076] In some embodiments, the specific implementation of step S1 may be:

[0077] S11, acquiring a slope area in a remote sensing image according to a geological analysis model, and performing geological analysis on the slope area to obtain geological parameters of the slope area, wherein the geological parameters include at least a slope gradient and a slope height.

[0078] The slope area refers to the slope area with a certain inclination angle in the remote sensing image. The geological parameters refer to the parameters that can describe the geological characteristics of the slope area, such as the slope gradient and height. The slope gradient refers to the inclination angle corresponding to the slope area. The slope height refers to the vertical distance between the uppermost edge and the lowermost edge of the slope.

[0079] When pre-training the geological analysis model, a large number of remote sensing images containing slope areas can be collected. These remote sensing images can cover different geological conditions and vegetation coverage. The collected remote sensing images are manually annotated to clearly mark the boundaries of the slope area. Then the annotated remote sensing images can be input into the model for training. By training the geological analysis model with a large number of remote sensing images, the geological analysis model can automatically identify and extract slope areas from the remote sensing images.

[0080] After obtaining the slope area, a geological analysis can be performed on the slope area to obtain the slope height and slope gradient corresponding to the slope area. Specifically, the digital elevation model data corresponding to the remote sensing image can be obtained. The remote sensing image and the digital elevation model data are matched in spatial coordinates. For any point in the remote sensing image, the corresponding elevation value can be found in the digital elevation model data. The slope height can be determined by the difference between the elevation values corresponding to the highest point and the lowest point in the slope area.

[0081] When obtaining the slope gradient, two points can be selected in the slope area as the upper and lower edges of the slope. According to the positions of the selected points, the corresponding elevation values are obtained from the extracted elevation data. According to the actual situation of the slope, a suitable inclination calculation method is selected. For example, a percentage method based on the elevation difference and the slope length can be selected. According to the selected calculation method, the inclination of the slope, that is, the slope gradient, can be calculated.

[0082] S12, obtaining vegetation parameters of the slope area, calculating a geological influence coefficient based on the geological parameters, and calculating a vegetation influence coefficient based on the vegetation parameters.

[0083] It is understandable that the geological parameters corresponding to the slope area will have an impact on slope collapse. The higher the slope gradient, the greater the inclination of the slope, and the more likely the soil and rock materials will slide under the action of gravity, so the risk of collapse may be greater. Similarly, the higher the slope height, the greater the pressure on the soil and rock materials above the slope, which may also increase the risk of collapse. In addition to the impact of geological parameters on slope collapse, the vegetation coverage rate of the slope area will also have an impact on the collapse. The slope surface lacking vegetation is more susceptible to weathering, resulting in the breakage and falling of soil and rocks, thereby increasing the risk of slope collapse. Therefore, when the vegetation coverage rate is low, the risk of slope collapse may be higher.

[0084] In actual applications, there may be many slope areas, and not every slope area needs to be protected by a protective net. If the vegetation coverage rate of the slope area is high, a large amount of vegetation will provide certain protection to the slope area, and a protective net may not be needed for protection. However, if the slope area may have the risk of collapse and falling rocks, it can be protected by a protective net. Therefore, this solution can assess the risk of slope collapse by combining parameters of multiple dimensions such as slope gradient, slope height and vegetation coverage, thereby improving the accuracy of the assessment, and subsequently combining the data after the assessment to determine whether the slope area needs protection by a protective net and the type of protective net required.

[0085] Specifically, the vegetation parameters corresponding to the slope area can be obtained through remote sensing images. Based on the vegetation parameters, the degree of influence of the vegetation in the slope area on collapse, that is, the vegetation influence coefficient, can be calculated. Based on the geological parameters, the degree of influence of the slope area's slope and height on collapse, that is, the geological influence coefficient, can be calculated. Based on the influence coefficients of multiple dimensions, the collapse risk of the slope area can be assessed more accurately.

[0086] Among them, vegetation parameters refer to parameters that can be used to describe the vegetation coverage of the slope area, such as vegetation coverage rate; the geological influence coefficient is a coefficient that can reflect the degree of influence of geological parameters on the risk of slope collapse; and the vegetation influence coefficient is a coefficient that can reflect the degree of influence of vegetation coverage on the risk of slope collapse.

[0087] Based on the above embodiment, the specific implementation of step S12 may be:

[0088] S121 , determining the vegetation coverage of the slope area according to the vegetation parameters, and obtaining a coverage ratio based on a ratio of a reference coverage ratio to the vegetation coverage ratio.

[0089] Specifically, in remote sensing images, the pixel values corresponding to the pixels in the vegetation-covered area are different from the pixel values corresponding to the pixels in the non-vegetation-covered area. The pixel value interval corresponding to the vegetation-covered area can be pre-configured, for example, the pixel value interval corresponding to green. The pixel values corresponding to multiple pixel points in the slope area of the remote sensing image are compared with the pixel value interval. If the pixel value of the pixel point is within the pixel value interval, the corresponding pixel point can be considered as a pixel point in the vegetation-covered area. The number of pixel points located in the vegetation-covered area is counted, and the ratio of this number to the total number of pixel points corresponding to the slope area is calculated to obtain the vegetation coverage rate corresponding to the slope area. The higher the vegetation coverage rate, the lower the collapse risk corresponding to the slope area. By calculating the ratio of the pre-configured benchmark coverage rate to the vegetation coverage rate, the corresponding coverage ratio can be obtained.

[0090] Among them, vegetation coverage refers to the proportion of vegetation coverage in the slope area, benchmark coverage refers to a pre-configured value that can be used to represent the vegetation coverage degree of the slope area under standard conditions, and coverage ratio refers to the ratio of the benchmark coverage rate of the slope area to the vegetation coverage rate.

[0091] S122: Obtain the vegetation adjustment weight configured by the management terminal, and obtain a vegetation impact coefficient according to the product of the coverage ratio and the vegetation adjustment weight.

[0092] In practical applications, different factors may have different degrees of influence on slope collapse. For example, when assessing the risk of slope collapse, the influence of factors such as vegetation coverage, slope gradient, and slope height may all be different. Reasonable weights can be assigned to each factor to obtain more accurate collapse risk data. For example, if the vegetation coverage of the slope area has a greater impact on the collapse risk, a higher weight can be assigned to the vegetation coverage factor.

[0093] Specifically, managers can assign corresponding weight values, namely vegetation adjustment weights, to vegetation parameters based on their importance in assessing slope collapse risks. By multiplying the vegetation adjustment weights with the coverage ratio, the coverage ratio can be adjusted to obtain the corresponding vegetation impact coefficient. The larger the vegetation impact coefficient, the greater the impact of vegetation coverage on slope collapse risk.

[0094] Among them, the management end refers to the terminal held by the manager of the slope area, such as a computer, and the vegetation adjustment weight refers to a data indicator that can be used to measure the importance of vegetation coverage in assessing the risk of slope collapse.

[0095] S123: Obtain a side slope gradient ratio according to a ratio of the side slope gradient to a reference side slope gradient, and obtain a side slope gradient influence coefficient based on a product of a side slope gradient adjustment weight and the side slope gradient ratio.

[0096] Specifically, by calculating the ratio of the slope gradient to the pre-configured reference slope gradient, the corresponding slope gradient ratio can be obtained. The slope gradient ratio can reflect the degree of deviation of the actual slope gradient from the reference slope gradient. The larger the slope gradient ratio, the greater the degree of deviation of the actual slope gradient from the reference slope gradient, the lower the stability of the slope may be, and the higher the corresponding collapse risk of the slope may be.

[0097] After obtaining the slope gradient ratio, managers can also assign corresponding weight values, namely, slope adjustment weights, to the slope gradient according to its importance in assessing the risk of slope collapse. By multiplying the slope adjustment weight with the slope gradient ratio, the slope gradient ratio can be adjusted to obtain the corresponding slope gradient influence coefficient. The larger the slope gradient influence coefficient, the greater the impact of the slope gradient on the risk of slope collapse.

[0098] Among them, the reference slope gradient refers to a pre-configured standard slope that can be used to evaluate slope stability; the slope gradient ratio refers to the ratio of the slope gradient to the reference slope gradient; the slope adjustment weight refers to a data indicator that can be used to measure the importance of the slope gradient in evaluating the risk of slope collapse; and the slope gradient influence coefficient refers to a coefficient that can reflect the degree of influence of the slope gradient on the risk of slope collapse.

[0099] S124, obtaining a slope height ratio based on the ratio of the slope height to the reference slope height, obtaining a slope height influence coefficient according to the product of the slope height adjustment weight and the slope height ratio, and summing the slope gradient influence coefficient and the slope height influence coefficient to obtain a geological influence coefficient.

[0100] Specifically, by calculating the ratio of the slope height to the pre-configured reference slope height, the corresponding slope height ratio can be obtained. The slope height ratio can also reflect the degree of deviation of the actual slope height from the reference slope height. The larger the slope height ratio, the greater the degree of deviation of the actual slope height from the reference slope height, the lower the stability of the slope may be, and the higher the corresponding collapse risk of the slope may be.

[0101] After obtaining the slope height ratio, managers can assign corresponding weight values, namely, height adjustment weights, to the slope height according to its importance in assessing the risk of slope collapse. By multiplying the height adjustment weight by the slope height ratio, the slope height ratio can be adjusted to obtain the corresponding slope height influence coefficient. The larger the slope height influence coefficient, the greater the influence of the slope height on the risk of slope collapse. Since geological parameters include slope gradient and slope height, the corresponding geological influence coefficient can be obtained by summing the slope gradient influence coefficient and the slope height influence coefficient.

[0102] Among them, the reference slope height refers to a pre-configured standard height that can be used to evaluate slope stability; the slope gradient ratio refers to the ratio of the slope height to the reference slope height; the height adjustment weight refers to a data indicator that can be used to measure the importance of slope height in evaluating slope collapse risk; and the slope height influence coefficient refers to a coefficient that can reflect the degree of influence of slope height on slope collapse risk.

[0103] S13, summing the geological influence coefficient and the vegetation influence coefficient to obtain a risk coefficient, and determining a slope area where the risk coefficient is greater than or equal to a risk threshold as a risk area.

[0104] Specifically, by adding the geological influence coefficient and the vegetation influence coefficient, the risk coefficient corresponding to the slope area can be obtained. The higher the risk coefficient, the greater the risk of slope collapse. A risk threshold can be set in advance. When the risk coefficient exceeds the risk threshold, it can be considered that the corresponding slope area is very likely to collapse and there may be a risk of falling rocks. A protective net needs to be installed for protection. The corresponding slope area can be identified as a risk area. Subsequently, the risk of collapse and falling rocks can be further analyzed for the slopes that need protection, so that the specific type of protective net can be determined.

[0105] Among them, the risk coefficient refers to the coefficient used to indicate the risk of collapse in the slope area. The larger the risk coefficient, the greater the risk of collapse. The risk threshold refers to a pre-set threshold that can be used to determine whether there is a risk of collapse in the slope area. When the risk coefficient exceeds the risk threshold, it can be considered that the corresponding slope area has a risk of collapse. If the risk coefficient is less than the risk threshold, it can be considered that the corresponding slope area may not have a risk of collapse. The risk area refers to the slope area where the risk coefficient is greater than or equal to the risk threshold.

[0106] Through the above implementation, the risk assessment of slope collapse can be performed through parameters of multiple dimensions, thereby improving the accuracy of the assessment.

[0107] S2, determining the protection type of the risk area, which includes a single protection type and a combined protection type, and generating protection configuration data according to the protection type and sending it to the operation end.

[0108] Among them, the protection type refers to the type of protection for the risk area. The single protection type refers to the protection type with only one protection net, for example, it can be a protection type that only includes active protection nets, or it can be a protection type that only includes passive protection nets. The combined protection type refers to the protection type that includes two different protection nets, for example, it can be a protection type that combines active protection nets and passive protection nets. The protection configuration data refers to the specification and size data of the protection net, and the operation terminal refers to the terminal held by the staff who lay the protection net.

[0109] It is understandable that the geological information and vegetation coverage corresponding to different slope areas may be different, and the protection types required for different geological information and different vegetation coverage are also different. For example, for slope areas with low slope gradient, low slope height and high vegetation coverage, it can be considered that the corresponding slope area has higher stability and the risk of slope collapse and rockfall may be lower. At this time, a passive protection net can be used to simply intercept the small amount of rockfall that may occur below the slope area. For slope areas with high slope gradient or high slope height, the risk of collapse may be higher, and active protection nets can be used for protection. For slope areas with large slope gradient changes, different slope heights, and uneven vegetation coverage, it may be necessary to combine active protection nets and passive protection nets for comprehensive protection to ensure that the slope is comprehensively and effectively protected.

[0110] Specifically, in order to determine the type of protective net suitable for the risk area, it is possible to determine whether the protection type required for the risk area is a single protection type using one protective net, or a combined protection type requiring a combination of two protective nets, based on parameters such as the slope gradient, slope height, and vegetation coverage corresponding to the risk area. After obtaining the protection type corresponding to the risk area, the specifications of each protective net can be determined according to the protection type, and the corresponding protection configuration data can be generated and sent to the operation end.

[0111] In some embodiments, step S2 includes S21 to S25, which are specifically as follows:

[0112] S21, obtaining a risk area where the slope gradient is less than a slope threshold, the slope height is less than a height threshold, and the vegetation coverage is greater than a coverage threshold as a low-risk area.

[0113] Specifically, if the slope of the risk area is less than the slope threshold, it can be considered that the corresponding risk area is relatively gentle. At this time, the gravity component of the soil and rock along the slope direction of the slope is small, which means that the slope is not easy to slide or collapse due to gravity. Therefore, the collapse risk of the gentle slope is low. If the slope height of the risk area is less than the height threshold, it can be considered that the corresponding risk area is not very high. The lower slope height means that its gravitational potential energy is smaller. Even if a collapse occurs, the corresponding impact range will be relatively small. If the vegetation coverage rate of the risk area is greater than the coverage rate threshold, it can be considered that the corresponding vegetation in the risk area is more. More vegetation can improve the overall stability of the slope and reduce the risk of slope collapse. Therefore, when the above three conditions are met at the same time, it can be considered that the stability of the corresponding risk area is higher, the corresponding collapse risk is lower, and the corresponding risk area can be determined as a low-risk area.

[0114] Among them, the slope threshold refers to a pre-set value, which can be used to determine whether the inclination of the slope is within a stable range. When the slope of the slope is less than the slope threshold, it can be considered that the slope is relatively flat, its stability is high, and it is not prone to collapse. When the slope of the slope is greater than the slope threshold, it can be considered that the slope is relatively steep and its stability is low. The height threshold is a preset value, which can be used to determine whether the height of the slope is too high. When the height of the slope is less than the threshold, it can be considered that the height of the slope is not high and is not prone to collapse. When the height of the slope is greater than the threshold, it can be considered that the height of the slope is relatively high. The coverage rate threshold is also a preset value, which can be used to determine whether the vegetation coverage in the risk area is sufficient. When the vegetation coverage rate in the risk area exceeds the threshold, it can be considered that the vegetation coverage of the slope is good, and the collapse risk of the risk area can be considered relatively low. The low risk area refers to a risk area with a low collapse risk.

[0115] S22: Determine that the protection type of the low-risk area is a passive protection type in a single protection type, where the single protection type includes an active protection type and a passive protection type.

[0116] In practical applications, there are two types of single protection. One is the active protection type that lays an active protection net on the slope surface, which can limit the weathering and collapse of the rock on the slope surface, and actively reinforce and protect the slope. This type of protection is mainly suitable for slope areas with higher collapse risks. The other is the passive protection type that installs a passive protection net under the slope to intercept a small amount of falling rocks during collapse. This type of protection is suitable for slope areas with lower collapse risks. Therefore, when protecting the risk area, the corresponding protection type can be determined according to the type of risk area.

[0117] Specifically, when the risk area is determined to be a low-risk area, it can be considered that the collapse risk corresponding to the risk area is very small. For the low-risk area, a passive protection net can be installed under the slope area to intercept the small amount of falling rocks that may occur, thereby achieving protection for the slope area with a lower collapse risk. Therefore, it can be determined that the protection type corresponding to the low-risk area is the passive protection type.

[0118] Among them, the active protection type refers to the type of protection provided by an active protection net, and the passive protection type refers to the type of protection provided by a passive protection net.

[0119] S23, obtaining a risk area where the slope gradient is greater than or equal to the slope gradient threshold, the slope height is greater than or equal to the height threshold, or the vegetation coverage is less than the coverage threshold as a high-risk area.

[0120] Specifically, if the slope of the risk area is greater than the slope threshold, the corresponding risk area can be considered to be steeper. At this time, the force of the gravity component of the soil and rock along the slope direction also increases, causing the slope to be more susceptible to gravity and slide or collapse. Therefore, the collapse risk corresponding to the risk area can be considered to be higher. If the slope height is greater than or equal to the height threshold, the corresponding risk area can be considered to be higher. Since the higher the slope, the greater its potential gravitational potential energy, once the slope collapses, the corresponding impact range will be wider. If the vegetation coverage rate corresponding to the risk area is less than the coverage rate threshold, it can be considered that the vegetation in the risk area is less, and the soil on the slope may be more susceptible to weathering and erosion, resulting in reduced stability of the slope, and further leading to a higher risk of collapse in the risk area. When any one or more of the above three conditions are met, it can be considered that the stability of the corresponding risk area is lower, the risk of collapse is higher, and the corresponding risk area can be determined as a high-risk area.

[0121] Among them, high-risk areas refer to risk areas with higher collapse risks.

[0122] S24, determining that the high-risk area with a risk coefficient less than a high-risk threshold corresponds to the active protection type, and determining that the high-risk area with a risk coefficient greater than or equal to the high-risk threshold corresponds to the combined protection type.

[0123] In actual applications, when a risk area is determined to be a high-risk area, the corresponding risk degree is different due to the different risk coefficients corresponding to the high-risk areas. The larger the risk coefficient, the greater the degree of high risk. The protection requirements corresponding to high-risk areas are different depending on the degree of high risk. Therefore, the type of protection that should be adopted in high-risk areas can be determined according to the level of the risk coefficient.

[0124] Specifically, a high-risk threshold can be set in advance. When the risk coefficient is less than the high-risk threshold, it means that the high-risk level of the high-risk area is relatively low, and the slope can be protected by the active protection net. Therefore, the protection type of the corresponding high-risk area can be determined as the active protection type. When the risk coefficient is greater than or equal to the high-risk threshold, it means that the risk level of the high-risk area is high. Using an active protection net alone may not be able to meet the protection needs of the area. At this time, the passive protection net can be combined to form an interception net below the slope area with the risk of falling rocks, thereby further reducing the damage caused by falling rocks or sliding rock and soil to the area below. Therefore, the protection type of the corresponding high-risk area can be determined as a combined protection type.

[0125] Among them, the high-risk threshold refers to the threshold that can be used to measure the risk level of the high-risk area. If the risk coefficient of the high-risk area is greater than the high-risk threshold, it can be considered that the risk level of the corresponding high-risk area is high. If the risk coefficient of the high-risk area is less than the high-risk threshold, it can be considered that the risk level of the corresponding high-risk area is not high.

[0126] S25, determining the protective equipment corresponding to the risk area according to the protection type, the protective equipment including active protective equipment and passive protective equipment, determining the protection configuration data of the protective equipment according to the regional parameters of the risk area and sending it to the operation end.

[0127] Among them, protective equipment refers to equipment for protecting risk areas, such as protective nets. Active protective equipment can be active protective nets laid on the slope area to reinforce the rocks on the slope. Passive protective equipment can be passive protective nets laid under the slope area through brackets to intercept possible falling rocks. Area parameters refer to the specification parameters of the risk area, such as length, width, etc.

[0128] In actual applications, different protection types have corresponding protective equipment. Therefore, the corresponding protective equipment can be determined according to the protection type of the risk area. For example, when the protection type of the risk area is a passive protection type, the protective equipment corresponding to the risk area can be a passive protection equipment. When the protection type of the risk area is an active protection type, the protective equipment corresponding to the risk area can be an active protection equipment. When the protection type of the risk area is a combined protection type, the protective equipment corresponding to the risk area can include both active and passive protection equipment.

[0129] After determining the protective equipment corresponding to the risk area, it is necessary to determine the laying specifications of the protective equipment. Since the area sizes of different risk areas are different, the specifications of the required protective equipment are also different. Therefore, the laying length and laying width of the protective equipment can be planned according to the area size of the risk area, that is, the protection configuration data. The protection configuration data can be sent to the operation end, and the staff responsible for laying the protective net can refer to the protection configuration data to perform the corresponding protective net installation work.

[0130] Through the above implementation, the risk area can be accurately divided into low-risk areas and high-risk areas, and accurate protection of the risk area can be achieved, thereby minimizing the risk of slope collapse and improving the safety of the entire slope area.

[0131] In some embodiments, the specific implementation of step S25 may be:

[0132] S251 : Determine whether the passive protection type corresponds to the passive protection device, obtain the slope length of the risk area, and determine a first protection length of the passive protection device according to the slope length.

[0133] Specifically, if the protection type corresponding to the risk area is a passive protection type, then the corresponding protection equipment can be determined as a passive protection equipment. In order to determine the laying length of the passive protection equipment, the slope length of the risk area can be obtained according to the remote sensing image, and the slope length can be determined as the laying length of the passive protection equipment, that is, the first protection length.

[0134] Among them, the slope length refers to the regional length of the risk area, and the first protection length refers to the laying length of the passive protection net.

[0135] S252: Obtain a preset width corresponding to the geological parameters of the risk zone, and obtain protection configuration data of the passive protection device according to the first protection length and the preset width.

[0136] When planning the protection configuration data of passive protection equipment, in addition to determining the laying length of the passive protection net on the slope, it is also necessary to consider the width of the passive protection net to be laid. Since the higher the slope, the greater the potential energy of potential falling rocks or collapsed rocks, the possible ground impact range will also be correspondingly expanded. Similarly, the slope gradient will also affect the movement trajectory and speed of falling rocks, and thus affect the range of their impact on the ground. In order to ensure that the passive protection equipment can effectively intercept and reduce the impact of disasters on the ground when disasters such as collapse or falling rocks occur, the laying width of the passive protection equipment can be determined in combination with the slope height and slope gradient corresponding to the risk area.

[0137] Specifically, in order to more accurately determine the laying width corresponding to the passive protection equipment, a table can be pre-configured, which lists the preset width values corresponding to different slope and height combinations. By traversing the table according to the slope gradient and slope width of the risk area, a preset width that matches the slope gradient and slope height can be obtained. If the slope is higher or the height is larger, the impact range on the ground when collapse or rockfall occurs may be wider, so the corresponding preset width will also increase accordingly. The obtained preset width can be determined as the laying width of the passive protection equipment. Therefore, the protection configuration data of the passive protection equipment can be determined based on the preset width and the first protection length. The staff responsible for laying the protection net can refer to the protection configuration data to perform the corresponding passive protection equipment installation work.

[0138] The preset width refers to a pre-configured width value corresponding to the parameters of the risk zone, and the first protection length refers to the laying width of the passive protection equipment corresponding to the passive protection type.

[0139] S253, determining that the active protection type corresponds to the active protection device, determining a second protection length and a second protection width of the active protection device according to the slope length and the slope height, and obtaining protection configuration data of the active protection device based on the second protection length and the second protection width.

[0140] If the protection type corresponding to the risk area is active protection type, then the corresponding protection equipment can be determined as active protection equipment. Since when the risk area is protected by active protection equipment, the active protection equipment is laid on the slope surface to reinforce the slope, the laying specifications of the active protection equipment can be determined according to the length and width of the risk area.

[0141] Specifically, the laying length of the active protection equipment can be determined according to the length of the slope. Since there may be protruding rocks or irregular terrain on the slope surface, a certain reserved length can be added on the basis of the slope length to ensure that the protection equipment can fully cover the risk area. The sum of the slope length and the reserved length can be determined as the second protection length of the active protection equipment. When determining the laying width of the active protection net, the oblique length of the slope surface can be determined according to the slope height and slope gradient. The laying width of the active protection net can be determined according to the oblique length of the slope surface. Similarly, in order to ensure that the protection equipment can fully cover the risk area, a certain reserved width can be added on the basis of the oblique length of the slope surface. The sum of the oblique length of the slope surface and the reserved width can be determined as the second protection width of the active protection equipment. The protection configuration data corresponding to the active protection equipment can be determined according to the second protection length and the second protection width. The operators responsible for laying the protection net can refer to the protection configuration data to perform the corresponding installation work of the active protection equipment.

[0142] When the oblique length of the slope surface can be determined based on the slope height and slope gradient, the slope gradient and slope height of the slope are known, and the sine function in the trigonometric function can be used to calculate to obtain the oblique length of the slope surface, and the second protection width of the active protection device can be determined based on the oblique length of the slope surface.

[0143] The second protection length refers to the length of the active protection device corresponding to the active protection type, and the second protection width refers to the width of the active protection device corresponding to the active protection type.

[0144] S254, determining the combined protection type corresponding to the combined protection equipment, determining the active equipment specifications of the combined protection equipment according to the slope length and slope height, obtaining the reinforcement area in the risk area, and determining the passive equipment specifications of the combined protection equipment according to the area length of the reinforcement area.

[0145] In actual applications, when the protection type of the risk area is a combined protection type, it can be determined that the protection equipment corresponding to the risk area includes both active protection equipment and passive protection equipment. Active protection equipment can be laid for protection of the entire risk area. Therefore, the specifications of the active protection equipment can be determined according to the slope length and slope height of the risk area. Since the slope area may be long, not all areas are at risk of falling rocks. This solution can perform passive protection on a certain section of the area with the risk of falling rocks, thereby achieving targeted reinforcement protection. Therefore, the reinforcement area in the risk area can be obtained first, and the specifications of the passive protection equipment can be determined according to the area length of the reinforcement area.

[0146] Among them, the active equipment specifications refer to the length and width of the active protection equipment corresponding to the combined protection type, the reinforcement area refers to the area that requires passive protection equipment for reinforcement and protection, the area length refers to the length of the reinforcement area, and the passive equipment specifications refer to the length and width of the passive protection equipment corresponding to the combined protection type.

[0147] In some embodiments, step S254 of "determining the active equipment specifications of the combined protective device according to the slope length and slope height, obtaining the reinforcement area in the risk area, and determining the passive equipment specifications of the combined protective device according to the area length of the reinforcement area" includes the following steps:

[0148] S2541 , determining a third protection length and a third protection width of the active protection device in the combined protection device based on the slope length and the slope width, and obtaining active device specifications according to the third protection length and the third protection width.

[0149] Specifically, when obtaining the specifications corresponding to the active protection device in the combined protection device, the third protection length and third protection width corresponding to the active protection device can be determined in the same way as obtaining the second protection length and second protection width, and then the corresponding active device specifications can be obtained.

[0150] The third protection length refers to the length of the active protection device in the combined protection device, and the third protection width refers to the width of the active protection device in the combined protection device.

[0151] S2542: Determine the length direction corresponding to the slope length, draw a plurality of determination lines perpendicular to the length direction at predetermined intervals in the length direction, and divide the risk area into a plurality of determination areas according to the determination lines.

[0152] In actual applications, the risk zone may be long and complex, and directly assessing the rockfall risk of the entire area may not be accurate enough. In order to more accurately determine the area with a higher risk of rockfall, the risk zone can be divided into multiple small areas, so that a more detailed risk assessment can be performed on each area.

[0153] Specifically, the risk area can be divided into regions based on remote sensing images. The extension direction of the slope can be determined according to the remote sensing images, and the extension direction can be determined as the length direction. In the length direction, multiple judgment lines perpendicular to the length direction are generated at pre-set intervals, and the risk area is divided into multiple smaller judgment areas. The vegetation coverage rate of each area can be evaluated separately subsequently, so that the rockfall risk can be judged more accurately.

[0154] Among them, the length direction can be the extension direction of the slope area, the preset distance refers to the distance between adjacent pre-set judgment lines, the judgment line refers to the line that can be used to divide the risk area into regions, and the judgment area refers to multiple areas obtained after dividing the risk area into regions.

[0155] S2543, obtain the vegetation coverage rate of each of the judgment areas, determine that the judgment area with the vegetation coverage rate less than the low coverage threshold is the reinforcement area, obtain the area length of the reinforcement area in the length direction, and determine the fourth protection length of the passive protection equipment in the combined protection equipment according to the area length.

[0156] Specifically, for the entire risk area, the vegetation coverage rate may be uneven, and the vegetation coverage rates corresponding to different judgment areas may be different. In order to more accurately assess the rockfall risk of each judgment area, the vegetation coverage rate corresponding to each judgment area can be obtained through remote sensing images. The lower the vegetation coverage rate, the weaker the protective effect of the soil and the greater the risk of rockfall. When the vegetation coverage rate is too low, the soil is easily eroded by rain and wind, the stability of the slope is poor, and the risk of rockfall is high. In this case, passive protection nets can be added for reinforcement and protection. In order to determine whether the vegetation coverage rate of the judgment area is too low and whether passive protection nets need to be added for reinforcement and protection, a low coverage threshold can be pre-configured. When the vegetation coverage rate of the judgment area is lower than the threshold, it can be considered that the soil protection effect of the judgment area is weak, the vegetation coverage rate is too low, the rockfall risk may be high, and passive protection nets need to be added for interception and protection. Therefore, the judgment area can be determined as a reinforcement area.

[0157] See also Figure 2 , which is a schematic diagram of determining a reinforcement area provided by an embodiment of the present invention, such as Figure 2 As shown in , in the length direction, the risk area can be divided into determination area 1, determination area 2 and determination area 3 by multiple determination lines perpendicular to the length direction, and the vegetation coverage rate corresponding to each determination area can be obtained. It is obvious that the vegetation coverage rate of determination area 1 and determination area 2 is low, and the vegetation coverage rate of determination area 3 is relatively high. When the vegetation coverage rate of determination area 1 and determination area 2 is less than the low coverage threshold, determination area 1 and determination area 2 can be determined as reinforcement areas.

[0158] After obtaining the reinforcement area, the length of the reinforcement area in the longitudinal direction can be obtained, and the length of the area can be determined as the laying length of the passive protection device in the combined protection device, that is, the fourth protection length. It is worth noting that if there are adjacent reinforcement areas in the risk area, the adjacent reinforcement areas can be merged, and the fourth protection length corresponding to the passive protection device can be determined according to the length of the merged area, for example Figure 2As shown in , since both determination area 1 and determination area 2 are determined as reinforcement areas, the two reinforcement areas can be merged to obtain the area length of determination area 1 and the area length of determination area 2, and the corresponding area lengths are added together to determine the fourth protection length of the passive protection device.

[0159] S2544, determine the maximum height and reinforcement slope of the reinforcement area, obtain a geological parameter correspondence table, traverse the geological parameter correspondence table according to the maximum height and reinforcement slope, and determine that the preset width corresponding to the maximum height and reinforcement slope is the fourth protection width.

[0160] In actual applications, after the risk area is divided into regions, the slopes and heights corresponding to different judgment areas may be different. Since the slope and height of the slope will affect the impact range of falling rocks on the ground, when determining the laying width of passive protection equipment, it can be determined based on the highest height and slope of the reinforced area.

[0161] Specifically, a pre-configured geological parameter correspondence table can be retrieved, which can be consistent with the pre-configured table when obtaining the first protection width, and the geological parameter table can be presented in the form of a two-dimensional table. The horizontal axis represents the slope range, and the vertical axis represents the height range. Each intersection corresponds to a preset width value. The slope gradient and slope height corresponding to each reinforcement area can be obtained based on the remote sensing image. In order to ensure that the passive protection equipment can protect the reinforcement area more comprehensively, the maximum slope height can be determined as the maximum height, and the maximum slope gradient can be determined as the reinforcement slope. According to the maximum height and the reinforcement slope, the geological parameter correspondence table is traversed, and the most matching height range and slope range are found in the geological parameter correspondence table, so that the corresponding preset width value can be determined, and the corresponding preset width can be determined as the laying width of the passive protection equipment, that is, the fourth protection width.

[0162] For example, in the geological parameter table, the height interval 1 is 0m-15m, the height interval 2 is 15m-30m, the slope interval 1 is 0°-15°, and the slope interval 2 is 0°-15°. When the highest height of the reinforcement area is 21m and the reinforcement slope is 18°, the geological parameter table is traversed in combination with the highest height and the reinforcement slope, and it can be determined that the corresponding height interval is height interval 2, and the corresponding slope interval is slope interval 2. Therefore, the preset width value corresponding to the height interval 2 and the slope interval 2 can be determined as the fourth protection width of the passive protection equipment.

[0163] Among them, the highest height refers to the maximum height corresponding to the reinforcement area, the reinforcement slope refers to the maximum slope corresponding to the reinforcement area, the geological parameter correspondence table refers to a pre-configured table containing multiple height intervals, multiple slope intervals and their corresponding preset widths, and the fourth protection width refers to the width of the passive protection device in the combined protection device.

[0164] S2545, obtaining specifications of passive equipment according to the fourth protection length and the fourth protection width, wherein the geological parameter correspondence table includes a plurality of preset height intervals, preset slope intervals, and preset widths corresponding to the preset height intervals and the preset slope intervals.

[0165] Specifically, after the fourth protection width is obtained, the specification corresponding to the passive protection device in the combined protection device, ie, the passive device specification, can be obtained according to the fourth protection length and the fourth protection width.

[0166] Among them, the passive equipment specifications refer to the laying specifications corresponding to the passive protective equipment in the combined protective equipment, the preset height interval refers to the pre-configured height interval, and the preset slope interval refers to the pre-configured slope interval.

[0167] Through the above implementation method, comprehensive protection of the entire risk area is achieved, and targeted reinforcement and protection are carried out for reinforced areas with higher rockfall risks, thereby reducing the potential harm caused by disasters such as slope collapse and rockfall to the areas below.

[0168] S255 , obtaining protection configuration data of the combined protection device according to the active device specifications and the passive device specifications, wherein the area parameters include slope length, slope height, and slope gradient.

[0169] Specifically, after obtaining the passive device specifications, the protection configuration data of the combined protection device can be obtained by combining the active device specifications and the passive device specifications. The operators responsible for laying the protection net can refer to the protection configuration data of the combined protection device to perform the corresponding installation work of the combined protection device.

[0170] Through the above implementation, it can be ensured that the protective equipment matches the actual protection needs of the risk area, thereby improving the effectiveness and pertinence of the protection.

[0171] S3, determining an inspection strategy according to the protection type, and acquiring on-site data collected by monitoring equipment on the risk area based on the inspection strategy.

[0172] In actual applications, after installing the corresponding protective equipment, in order to be able to monitor the protective status of the protective net in real time, the monitoring equipment, such as drones, can be controlled to regularly inspect the risk area, so that when the protective status of the protective net is abnormal, timely processing can be carried out. For example, the protective net may accumulate falling rocks or deform. In addition, for different protection types, the corresponding inspection strategies are also different. For example, when there is only one protective device in the risk area, the monitoring equipment can be controlled to collect data on the protective status of one protective device. When there are multiple protective devices in the risk area, the monitoring equipment can be controlled to collect data on the protection conditions of multiple different protective devices. Therefore, the corresponding inspection strategy can be determined according to the protection type of the risk area. Combined with the corresponding inspection strategy, the monitoring equipment can be controlled to collect data on the protective status of the protective equipment, and the corresponding on-site data can be obtained. The on-site data can be analyzed later to determine whether the status of the protective equipment is abnormal.

[0173] Among them, the inspection strategy refers to the method of inspecting the risk area, the monitoring equipment refers to the equipment that can monitor the protection status of the risk area, such as a drone, and the field data refers to the image data corresponding to the risk area collected by the monitoring equipment.

[0174] Based on the above embodiment, the specific implementation of step S3 may be:

[0175] S31, determining that the single protection type corresponds to a single inspection strategy, and obtaining multiple inspection points corresponding to the protection equipment in the risk area according to the single inspection strategy.

[0176] Specifically, when the protection type corresponding to the risk area is a single protection type, it means that there is only one type of protective equipment in the risk area. It can be considered that the monitoring equipment only needs to collect data on the protection status of one type of protective equipment, and the corresponding inspection strategy can be determined as a single inspection strategy. When collecting data on the protection status of the protective equipment, since the risk area may be large, in order to collect more comprehensive on-site data of the protective equipment, the management personnel can pre-configure multiple points for data collection of the protective equipment, namely inspection points, and the shooting height and shooting posture at each inspection point are pre-set. Therefore, after determining a single inspection strategy, multiple inspection points corresponding to the protective equipment in the risk area can be obtained, and the monitoring equipment can be controlled to go to multiple inspection points for data collection.

[0177] Among them, a patrol inspection strategy refers to a strategy for collecting data on the protection status of a protective device, and a patrol inspection point refers to a point where data on the protective device is collected.

[0178] S32, generating a patrol route according to the patrol points, and controlling the monitoring device to sequentially go to each patrol point based on the patrol route to capture images and obtain the on-site data.

[0179] After obtaining multiple inspection points, an efficient inspection path can be generated based on the distribution of multiple inspection points and combined with the path optimization algorithm. Figure 3 , is a schematic diagram of a patrol route provided by an embodiment of the present invention, such as Figure 3 As shown in , the path starting point and the path ending point can be selected from multiple inspection points, for example Figure 3 In the example, inspection point 1 can be used as the starting point of the path, and inspection point 2 as the end point of the path. Starting from the starting point of the path, the closest inspection points are sequentially connected to generate a single inspection path. The generated single inspection path is the optimal inspection path, ensuring that the monitoring device can access all inspection points by the shortest path, improving inspection efficiency. After obtaining the single inspection path, the monitoring device can be controlled to sequentially travel along the single inspection path to each inspection point to capture images and obtain the corresponding field data. Among them, the single inspection path refers to the inspection path corresponding to a single protective device under the single inspection strategy.

[0180] S33, determining that the combined protection type corresponds to a multiple inspection strategy, obtaining inspection points corresponding to each protection device based on the multiple inspection strategy, and generating multiple inspection paths according to each inspection point.

[0181] Specifically, when the protection type corresponding to the risk area is a combined protection type, it means that there are multiple types of protective equipment in the risk area. It can be considered that the monitoring equipment needs to collect data on the protection status of multiple types of protective equipment, and the corresponding inspection strategy can be determined to be a multiple inspection strategy.

[0182] Under the multiple inspection strategy, the inspection points pre-configured by the management personnel for each protective device can be obtained respectively. Similarly, based on the distribution of multiple inspection points corresponding to each protective device and combined with the path optimization algorithm, multiple inspection paths corresponding to each protective device can be generated. Since there are multiple inspection devices, multiple multiple inspection paths can be obtained.

[0183] The multiple inspection strategy refers to a strategy for inspecting multiple protective devices, and the multiple inspection paths refer to the inspection paths corresponding to each protective device under the multiple inspection strategy.

[0184] S34, controlling the monitoring device to take images of each of the protective devices based on the multiple inspection paths to obtain on-site data of each of the protective devices.

[0185] Specifically, after obtaining multiple inspection paths, the monitoring equipment can be controlled to follow each inspection path and go to each inspection point on the inspection path in turn to take images, so as to obtain the field data corresponding to each protective device.

[0186] Through the above implementation, more comprehensive on-site data of the protective equipment can be collected, and the efficiency of data collection can be improved.

[0187] S4, performing protection status analysis on the field data based on the status analysis model, obtaining inspection result data and sending it to the management end.

[0188] After obtaining the on-site data, the on-site data can be analyzed to determine whether the protective net is deformed or whether there are too many fallen rocks on the protective net. If deformation occurs or there are too many fallen rocks, the corresponding personnel can be dispatched in time to deal with it.

[0189] Specifically, a pre-trained state analysis model can be called up, which can identify and analyze key information in the image data, such as the shape of the protective net, the outline of the falling rock, etc. By inputting the field data into the state analysis model, the state analysis model can perform a protection status analysis on the field data to determine whether there is an abnormality in the protective net, thereby obtaining the inspection result data, and sending the inspection result data to the management end. The management personnel at the management end can dispatch corresponding personnel for processing based on the inspection result data.

[0190] Among them, the status analysis model is a pre-trained model that can analyze the protection status of the protection net, and the inspection result data refers to the abnormal data of the protection net obtained after the protection status analysis of the on-site data.

[0191] Based on the above embodiment, the specific implementation of step S4 may be:

[0192] S41 , when the protective device is a passive protective device, extracting a rockfall profile corresponding to the field data based on the state analysis model.

[0193] Specifically, when the protective device is a passive protective device, by inputting field data corresponding to the passive protective device into the state analysis model, the outline of the falling rock on the passive protective device can be extracted from the field data.

[0194] The rockfall profile refers to the profile of the rockfall on the passive protection equipment extracted from the field data.

[0195] S42, counting the total rockfall area of the rockfall contour, obtaining the total protection area of the passive protection equipment in the field data, and obtaining the rockfall load ratio according to the ratio of the total rockfall area to the total protection area.

[0196] Specifically, when obtaining the on-site data of the passive protection equipment, since there are multiple inspection points, the on-site data contains image data of multiple inspection points, and the corresponding rockfall contours can be extracted from each image data. In order to ensure that the rockfall situation on the entire passive protection equipment can be accurately and comprehensively evaluated, the image data can be spliced according to the acquisition order of each image data to obtain the complete image data corresponding to the passive protection equipment. Then, the area of the rockfall contour in the complete image can be counted to obtain the corresponding total rockfall area. According to the complete image data corresponding to the passive protection equipment, the total area corresponding to the passive protection equipment can be obtained, that is, the total protection area. By calculating the ratio of the total rockfall area to the total protection area, the corresponding rockfall load ratio can be obtained.

[0197] Among them, the total rockfall area refers to the area corresponding to all rockfall contours on the passive protective equipment, the total protection area refers to the total area corresponding to the passive protective equipment, and the rockfall load ratio refers to the proportion of rockfall on the passive protective equipment.

[0198] S43, determining that the passive protection device with the rockfall load ratio greater than or equal to the reference load ratio is an abnormal protection device, and determining that the passive protection device with the rockfall load ratio less than the reference load ratio is a normal protection device.

[0199] Specifically, if the rockfall load ratio is greater than or equal to the benchmark load ratio, it can be considered that there are too many rocks falling on the passive protection device, and the passive protection device may be in an abnormal protection state. The corresponding passive protection device can be determined as an abnormal protection device. If the rockfall load ratio is less than the benchmark load ratio, it can be considered that there are not many rocks falling on the passive protection device, and the passive protection device is in a normal protection state. The corresponding passive protection device can be determined as a normal protection device.

[0200] Among them, the benchmark load ratio is a pre-set proportional value, which can be used to evaluate whether there are too many falling rocks on the passive protective equipment. The abnormal protective equipment refers to the passive protective equipment in the abnormal protection state, and the normal protective equipment refers to the passive protective equipment in the normal protection state.

[0201] S44: When the protective device is an active protective device, extracting a protective net contour corresponding to the field data based on the state analysis model.

[0202] When the protective device is an active protective device, whether it is abnormal can be determined by judging whether the shape of the active protective device has changed. Specifically, by inputting the field data corresponding to the passive protective device into the state analysis model, the outline of the protective net corresponding to the active protective device can be extracted from the field data. Subsequently, whether the shape of the active protective device has changed can be judged based on the outline of the protective net.

[0203] Among them, the protective net outline refers to the outline of the active protective net.

[0204] S45, obtaining the current deformation degree of the protection net contour, obtaining the measurement parameters collected by the inspection device according to the current deformation degree, and determining whether the active protection device is a normal protection device or an abnormal protection device based on the comparison result of the measurement parameters and the initial parameters.

[0205] After obtaining the outline of the protective net, if the outline of the protective net changes significantly compared to the initial outline of the protective net, it can be considered that the corresponding area may have accumulated fallen rocks due to a landslide. If there are too many accumulated fallen rocks, their weight and impact force may exceed the carrying capacity of the protective net, which may cause damage to the protective net. The current deformation degree of the protective net outline can be obtained, and the protection status of the active protection equipment can be judged based on the current deformation degree.

[0206] Specifically, in order to more accurately evaluate the protective status of the active protective equipment, the measurement parameters collected by the inspection equipment can be obtained based on the current deformation degree. By comparing these measurement parameters with the preset initial parameters, the comparison results can more accurately determine whether the active protective equipment is normal or abnormal.

[0207] The current deformation degree refers to the deformation degree of the protective net at the current moment, the measurement parameter refers to the measurement data of the bulge of the accumulated fallen rocks, and the initial parameter refers to the measurement data when there is no accumulated fallen rocks.

[0208] In some embodiments, the specific implementation of step S45 may be:

[0209] S451, retrieve the historical field data corresponding to the inspection point, and extract the historical protection network outline in the historical field data.

[0210] Specifically, the inspection equipment can regularly go to each inspection point to collect image data of the protective net. Therefore, each inspection point has corresponding historical field data. The historical field data corresponding to the inspection point can be retrieved for reference. By extracting the contour of the protective net from the historical field data, the corresponding historical protective net contour can be extracted.

[0211] The historical field data refers to the image data of the protective net collected by the inspection equipment at the inspection point at the historical time point, and the historical protective net outline refers to the outline of the protective net in the historical field data.

[0212] S452: Obtain the contour similarity between the contour of the protection net and the contour of the historical protection net, and determine a preset deformation degree corresponding to the contour similarity as a current deformation degree.

[0213] Specifically, the contour similarity comparison between the current protective net contour and the historical protective net contour can be performed to obtain the contour similarity between the protective net contour and the historical protective net contour. Then, this solution can pre-configure a table, which contains multiple similarity intervals, and each similarity interval has a corresponding preset deformation degree, and the greater the similarity, the smaller the corresponding preset deformation degree. After obtaining the contour similarity, the contour similarity can be compared with the pre-set table, and the similarity interval where the contour similarity is located can be obtained. The preset deformation degree corresponding to the similarity interval can be determined as the current deformation degree corresponding to the protective net contour.

[0214] S453: When the current deformation degree is greater than the deformation threshold, control the inspection device to go to the inspection point based on a preset height to perform distance measurement to obtain measurement parameters.

[0215] If the current deformation degree is greater than the deformation threshold, it can be considered that the current protective net contour has changed significantly, and the change may be caused by rockfall. In order to further determine whether there are too many rockfalls accumulated in the corresponding area, the inspection equipment can be controlled to go to the inspection point to measure the distance at a pre-set height to obtain the corresponding measurement parameters. If there is rockfall accumulation at the inspection point, the accumulated rockfall will cause the ground height of the area to change, so that the distance measurement result is different from that when there is no rockfall accumulation. For example, the measurement parameters of the corresponding area will be smaller than the parameters when there is no rockfall. Therefore, the severity of the rockfall accumulation can be evaluated based on the measurement parameters later.

[0216] Among them, the deformation threshold refers to a pre-set threshold that can be used to determine whether the outline of the protective net has changed significantly. If the current deformation degree is greater than the deformation threshold, it can be considered that the outline of the protective net has changed significantly. If the current deformation degree is less than the deformation threshold, it can be considered that the outline of the protective net has not changed significantly. The measurement parameter refers to the distance parameter obtained by the inspection equipment when measuring the distance to the inspection point.

[0217] S454, retrieve the initial parameters corresponding to the inspection point, obtain the distance difference between the measured parameters and the initial parameters, determine that the active protection equipment with the distance difference greater than or equal to the distance threshold is an abnormal protection equipment, and determine that the active protection equipment with the distance difference less than the distance threshold is a normal protection equipment.

[0218] Specifically, the distance measurement results when there is no accumulation of fallen rocks at the inspection point, that is, the initial parameters, can be retrieved. By comparing the measured parameters with the initial parameters, the distance difference between the two can be calculated. If the distance difference is greater than or equal to the distance threshold, it means that the ground height at the inspection point has changed significantly. It can be considered that there are a lot of fallen rocks accumulated at the inspection point. At this time, the active protection equipment may be in an abnormal protection state. The corresponding active protection equipment can be determined as an abnormal protection equipment. If the distance difference is less than the distance threshold, it means that the ground height at the inspection point has not changed significantly. At this time, it can be considered that the active protection equipment is in a normal protection state. The corresponding active protection equipment can be determined as a normal protection equipment.

[0219] The distance threshold refers to a pre-set threshold that can be used to measure whether the ground height at the inspection point has changed significantly. If the distance difference is greater than or equal to the distance threshold, it can be considered that the ground height at the inspection point has changed significantly. If the distance difference is less than the distance threshold, it can be considered that the ground height at the inspection point has not changed significantly.

[0220] Through the above implementation, the protection status of the active protection equipment can be evaluated more accurately.

[0221] S46, determining the protection position of the abnormal protection device, generating inspection result data according to the protection position, and sending it to the management end.

[0222] Specifically, each protective device has a corresponding protective position. If a protective device is determined to be an abnormal protective device, the protective position corresponding to the abnormal protective device can be obtained. According to the protective position, the corresponding inspection result data can be generated and sent to the management end. The management personnel of the management end can dispatch corresponding personnel to the corresponding position for processing.

[0223] Through the above implementation, the protection status of the protection equipment can be judged more accurately.
