[0002] Currently, highways carry a strong traffic capacity, facilitating people's travel and promoting economic development.

[0003] However, due to the large differences in the geographical environments of different highway sections on highways, geological disaster accidents such as slope collapses and ground collapses may occur in some highway sections. At this time, the dangerous early warning for geological disaster accidents is particularly important. A common method is to use a drone equipped with a camera to take pictures from the air, which has the advantages of flexible operation and low usage cost, and can provide image data within the target area in a short time. However, the inspection efficiency of this method is low, and the clarity of the obtained image data is easily affected by the weather, resulting in poor accuracy and timeliness of dangerous early warning.

[0033] Please refer to Figure 1 , Figure 1 which is a structural block diagram of a high-speed operation system provided by an embodiment of this application. As Figure 1As shown in the figure, the high-speed operation system 100 includes a server 110, a positioning tag 120, a radar device 130, and a terminal device 140. Among them, the positioning tag 120 can be any kind of positioning device on the market. Preferably, the positioning tag 120 is a Beidou positioning tag. The Beidou positioning tag is a positioning device integrating Beidou satellite navigation system technology. It uses the signals provided by the Beidou satellite system to perform precise position positioning. The Beidou positioning tag receives the navigation signals sent by Beidou satellites, uses satellite positioning technology to calculate its own geographical location information (also known as tag position information, specifically including longitude, latitude, altitude, etc.), and outputs this information in data form or transmits it to a specified location (i.e., the server 110) through the network. Among them, the radar device is used to collect radar images of the target area, and the specific collection process will be described in detail in the embodiments; and, the terminal device is an electronic device carried by the staff in the target area, specifically can be a mobile phone, a tablet, a smart wearable device (such as a wristwatch). Specifically, the server determines the observation positions near the highway where there are danger omens (the surface deformation amount is greater than the first deformation amount threshold) by obtaining the radar images of the target area regularly collected by the radar device, and then determines the target highway section that needs surface deformation monitoring. Then, through interaction with the terminal device of the staff, calibration positions are set for the target highway section to perform subsequent surface deformation monitoring, and dangerous warning operations adapted to the surface deformation of the target highway section are performed by regularly obtaining the tag position information collected by the positioning tag subsequently. A high-speed operation system 100 can serve one or more target areas. A high-speed operation system 100 can correspond to multiple servers 110 at the same time. One server 110 corresponds to multiple positioning tags 120. The positioning tags 120 are determined according to the actual environmental conditions of the determined target highway section. And one server 110 corresponds to one or more terminal devices 140 and radar devices 130. The numbers of the radar device 130 and the terminal device 140 are specifically determined by the needs of relevant staff.

[0034] Based on this, the embodiments of the present application provide a method for dangerous warning based on a highway section. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for dangerous warning based on a highway section provided by the embodiments of the present application. The method is applied to the server 110 in the high-speed operation system 100. The high-speed operation system 100 further includes a positioning tag 120, a radar device 130, and a terminal device 140. The radar device 130 is used to collect radar images of the target area, and the terminal device 140 is carried by the staff in the target area; the method includes:

[0036] Step S201: Obtain the radar images collected by the radar device according to the first acquisition period.

[0037] Among them, this step can use the Interferometric Synthetic Aperture Radar (InSAR) technology. Specifically, it is a remote sensing technology that uses the backscattering echo signals of the ground surface obtained by synthetic aperture radar for interferometric processing to extract three-dimensional information of the ground surface and high-precision deformation information. The specific steps for the radar device to collect radar images are as follows: The radar device is carried by a satellite or an aircraft. Then, the radar device emits microwave pulses to the ground and receives the echoes, thereby generating multiple high-resolution radar images corresponding to the target area at different time periods (the radar system has a clock corresponding to the first acquisition period, and the radar image acquisition operation is performed once in each first acquisition period). The phase difference between two or more radar images obtained from slightly different positions is used to accurately measure the ground surface deformation amounts occurring at multiple observation positions on the ground surface within the target area.

[0038] Step S202: If it is determined from the radar images that the ground surface deformation amount at any one observation position is greater than the first deformation amount threshold, and the shortest distance between the observation position and the center line of the highway within the target area is less than the preset distance, then, with the target position on the center line of the road mapped by the shortest distance as the center, determine the highway with a preset monitoring length as the target highway section.

[0039] Among them, when it is determined from the radar images that the ground surface deformation amount at any one observation position is greater than the first deformation amount threshold, and the shortest distance from the observation position to the center line of the road is less than the preset distance, this indicates that there is a tendency for the ground surface change at this observation position to evolve into a geological disaster event. And the fact that this observation position is close to the highway means that if a geological disaster event occurs at this location, the highway will be affected, resulting in vehicles being unable to pass or causing traffic accidents. Therefore, a section of the highway is determined as the target highway section based on this observation position, and further and more accurate ground surface deformation monitoring is performed on this target highway section to ensure that the occurrence of geological disaster events can be detected in a timely manner and early warnings can be issued, avoiding greater losses to vehicles or highway sections and protecting traffic safety and personnel safety. Among them, the preset monitoring length can be determined according to the shortest distance. For example, the longer the shortest distance, the shorter the preset monitoring length; conversely, the shorter the shortest distance, the longer the preset monitoring length. In this way, the number and scope of subsequent positioning tags placed can be effectively reduced, and the consumption of personnel and resources as well as the amount of data that the server needs to process can be reduced. The minimum length of the preset monitoring length can be determined according to the specific ground surface deformation amount at this observation position, and the minimum length of the preset monitoring length is in a direct proportional relationship with the ground surface deformation amount.

[0040] Step S203: Determine the label setting information corresponding to the target highway section according to the radar image.

[0041] The label setting information is used to indicate the setting positions of multiple positioning labels required for surface deformation monitoring of the target highway section.

[0042] In a possible embodiment, determining the label setting information corresponding to the target highway section according to the radar image includes: if there is no slope area on the current side of the target highway section being processed, determine the area along the line within a preset interval distance from the guardrail on the current side of the target highway section as the monitoring area; and determine the setting positions of the positioning labels in the monitoring area according to the preset label interval distance; if there is a slope area on the current side of the target highway section being processed, determine the geological structure characteristics and slope deformation characteristics corresponding to the slope area according to the latest obtained radar image; determine multiple monitoring areas in the slope area and the monitoring level corresponding to each monitoring area according to the geological structure characteristics and slope deformation characteristics; determine the setting positions of the positioning labels in the corresponding monitoring area according to the preset label density corresponding to each monitoring level.

[0043] Among them, the preset label density has a positive correlation with the monitoring level.

[0044] The target highway section has two sides. The server executes different strategies according to whether there is a slope area on the current side being processed to determine the monitoring area of the positioning label and the number of positioning labels to be arranged in the monitoring area. Among them, if there is no slope area (which can be a mountain body) on the current side, determine the area along the line with a preset interval distance from the guardrail as the monitoring area, that is, lay positioning labels along the target highway section, and the interval distance between any two adjacent positioning labels is the same, which is the label interval distance. The label interval distance should be appropriate and can be determined according to the geological environment of the target highway section to avoid ineffective monitoring of surface deformation due to too far an interval and further danger warning. If there is a slope area on the current side, use the radar image to divide multiple monitoring areas and the monitoring level of each monitoring area on the slope area according to the geological structure characteristics and slope deformation characteristics of the slope area. The monitoring level can be understood as the danger level of the area and is used to characterize the probability of events such as collapse and landslide occurring in this monitoring area. By configuring more positioning labels (a higher preset label density) for the monitoring area with a higher monitoring level, the accuracy and precision of monitoring surface deformation are improved, and further the accuracy and timeliness of danger warning are improved.

[0045] Exemplarily, please refer to Figure 3 , Figure 3 which is a schematic diagram of the scenario for setting positioning labels for the target highway section provided by the embodiment of the present application. AsFigure 3 As shown, the type of the terminal device carried by the staff can be a square dial watch or a round dial watch. After the server determines the label setting information corresponding to the target highway section, the server will send the label setting information to the terminal device for displaying the corresponding label setting information. Among them, the content of the screen displayed on the smart watch is that the left side of the target highway section is the slope area, and the right side of the target highway section is the non-slope area. When the server determines the label setting information for laying the positioning labels in the non-slope area, it lays the positioning labels along the target highway section, and the interval distance between any two adjacent positioning labels is the same. When the server determines the label setting information for laying the positioning labels in the slope area, it first divides the slope area into multiple monitoring areas according to the geological structure characteristics and slope deformation characteristics of the slope area, that is Figure 3 the circular part in the middle slope area, and sets the positioning labels with different preset label densities according to the monitoring levels of each monitoring area. Figure 3 In the figure, the monitoring levels of the first monitoring area and the second monitoring area from top to bottom are the same, and the corresponding label density is two, while the monitoring level of the third monitoring area is higher, and its corresponding label density is four. Setting more positioning labels for the monitoring area with a high monitoring level can improve the accuracy and precision of monitoring the surface deformation.

[0046] It can be seen that in this example, the server executes different label laying strategies according to the different geological conditions on both sides of the target highway section to determine the monitoring range and the setting positions of the positioning labels within the monitoring range, improving the flexibility of the server in laying the positioning labels and the accuracy of subsequent surface deformation monitoring.

[0047] Step S204, after interacting with the terminal device to complete the label setting operation based on the set position, obtain the label position information collected by each positioning label according to the second collection period to determine the surface deformation information.

[0048] Among them, the cycle duration of the second collection period is less than the cycle duration of the first collection period.

[0049] Among them, since the accuracy of the positioning label collecting the label position information to determine the associated information of the surface deformation is significantly higher than that of determining the surface deformation by collecting the radar image of the target area through the radar device, therefore, by collecting the high-frequency label position information (that is, setting the cycle duration of the second collection period to be less than the cycle duration of the first collection period), the accuracy and timeliness of the server's danger warning for the target highway section can be effectively improved, the practicability of the server can be improved, and the impact of geological disasters on the highway and the driving vehicles can be reduced.

[0050] Specifically, the specific steps for the server to interact with the terminal device to complete the label setting operation based on the set position include: 1. The server sends a label setting request instruction carrying label setting information to the terminal device; 2. The terminal device receives the label setting request instruction to obtain the setting positions of multiple positioning labels near the target highway section to be arranged; 3. The staff arranges the positioning labels one by one through these setting positions; 4. The positioning labels calculate and record the label position information in real time; 5. After the staff finishes arranging the positioning labels, a label setting response instruction is sent to the server through the terminal device. The label setting response instruction is used to indicate that the staff has completed the arrangement of the positioning labels; 6. The server responds to the label setting response instruction to determine that the label setting operation has been completed.

[0051] Furthermore, the positioning label can be set as an Internet of Things communication beacon, and a positioning antenna can be set on the Internet of Things communication beacon. The functions of the Internet of Things communication beacon include: 1. Communication standard: The beacon is a communication standard that coordinates and integrates the operation of each part of the communication system according to certain technical specifications and protocols to ensure the accurate transmission and effective communication of information. This is an indispensable part of the Internet of Things communication, providing a basis for the smooth communication between various devices and systems. 2. Ensure accurate information transmission: By stipulating a unified information coding and processing method, the beacon can ensure that the information is not distorted or misunderstood during the transmission process, thereby improving the reliability and accuracy of communication. 3. Promote interoperability: In a diverse Internet of Things environment, devices following the same beacon can understand and communicate with each other, promoting the interoperability between different systems and devices. Combining with the positioning label can improve the positioning accuracy and reliability. The beacon provides a stable communication environment and a unified standard for the positioning label, reducing errors and interference in the positioning process, thereby improving the positioning accuracy. Since the beacon cannot communicate after being buried underground and the communication power consumption is relatively large, the following two solutions can be adopted: The first installation method is: the positioning label and the solar panel, and the solar panel can supply power to the positioning label, and the positioning label is installed above the ground; The second installation method is: install at the street lamp position of the target highway section, directly install on the lamp post or under the lamp post, the beacon is buried under the lamp post and powered by the lamp post, and the positioning antenna is exposed above the ground; The second installation method is: the beacon is buried under the lamp post, the beacon is buried in the soil, and uses Internet of Things communication to transmit signals outward. A gateway is installed on the lamp post every 1 kilometer to receive the Internet of Things communication signals.

[0052] In a possible embodiment, the surface deformation information includes first deformation information determined by monitoring the ground deformation on the first side of the monitored target highway section, and second deformation information determined by monitoring the ground deformation on the second side of the monitored target highway section. The first side is any one of the two sides divided by the road center line. Obtaining the tag position information collected by each positioning tag according to the second collection period to determine the surface deformation information includes: obtaining the initial position information of each positioning tag; according to the initial position information, determining the positioning tag located on the first side of the target highway section as the first tag, and determining the positioning tag located on the second side of the target highway section as the second tag; when it is detected that the second collection period ends, determining the first deformation information at the current moment according to the tag position information corresponding to the first tag obtained in the current period and the corresponding initial position information; and when it is detected that the second collection period ends, determining the second deformation information at the current moment according to the tag position information corresponding to the second tag obtained in the current period and the initial position information; integrating the first deformation information and the second deformation information into the surface deformation information.

[0053] Wherein, the initial position information is the tag position information with the earliest collection time collected by the corresponding positioning tag.

[0054] Wherein, in order to improve the accuracy of monitoring surface deformation, the server divides the positioning tags into the first tag and the second tag by obtaining the tag position information with the earliest collection time (i.e., the initial position information) corresponding to each positioning tag located on the first side or the second side of the target highway section. Each time when the second collection period ends, the surface deformation information on the first side of the target highway section is determined according to the tag position information of the first tag on the first side, and the surface deformation information on the second side of the target highway section is determined according to the tag position information of the second tag on the second side, and during the subsequent data processing, the surface on both sides of the road center line of the target highway section is also monitored and warned respectively, improving the accuracy of warning.

[0055] It can be seen that in this example, since there may be obvious differences in the geological environment and terrain structure on both sides of the target highway section, the server differentiates the positioning tags into the first tag on the first side and the second tag on the second side through the initial position information of each positioning tag, and then determines the first deformation information on the first side of the target highway section for the first tag respectively, and determines the second deformation information on the second side of the target highway section for the second tag respectively, improving the flexibility and accuracy of the server in performing surface deformation analysis, and improving the accuracy of subsequent danger warning operations.

[0056] In a possible embodiment, the first deformation information at the current moment is determined based on the tag position information corresponding to the first tag obtained in the current cycle and the corresponding initial position information, including: determining the tag displacement amount and the tag displacement direction according to the tag position information of each first tag and the corresponding initial position information; determining the first tag with a corresponding tag displacement amount greater than the preset displacement amount as the reference tag; determining the overall deformation amount on the first side, as well as the first deformation component of the overall deformation amount in the horizontal direction and the second deformation component of the overall deformation amount in the height direction according to the tag displacement amount and the tag displacement direction of the reference tag; determining the initial coverage area according to the initial position information of the reference tag, and determining the current coverage area according to the tag position information of the reference tag in the current cycle; determining the disaster-stricken coverage area located within the target highway section according to the initial coverage area, the current coverage area, the first deformation component, and the second deformation component; and determining the first deformation information according to the disaster-stricken coverage area, the overall deformation amount, the first deformation component, and the second deformation component.

[0057] Among them, this embodiment is a specific implementation manner for the server to determine the first deformation information based on the tag position information and the initial position information of the first tag. It should be noted that the specific manner for the server to determine the second deformation information based on the tag position information and the initial position information of the second tag is the same as this, and the content types in the first deformation information and the second deformation information are the same, only the specific numerical values of each item of data are different.

[0058] Among them, the calculation process for determining the tag displacement amount and the tag displacement direction according to the tag position information of each first tag and the corresponding initial position information is as follows:

[0059] Assume that the initial position coordinates (i.e., the initial position information) are P0(x0, y0, z0), and the current position (i.e., the tag position information) coordinates are P1(x1, y1, z1). Then the total displacement amount d can be obtained through the following formula:

[0060] d 2 =(x1 - x0)2 + (y1 - y0) 2 +(z1 - z0) 2 , where d is the displacement amount of the corresponding positioning tag, that is, the straight-line distance from the initial position coordinates to the current position;

[0061] The tag displacement direction is represented by the displacement vector ΔP, and ΔP can be obtained through the following formula:

[0062] ΔP = (x1 - x0, y1 - y0, z1 - z0).

[0063] Among them, in order to improve the efficiency of calculating the overall deformation amount, the server filters out reference tags with large deformation displacement amounts through a preset displacement amount, and calculates the overall deformation amount on the first side of the target highway section based on the tag displacement amount of the reference tags and their corresponding tag displacement directions. And in order to determine the disaster types of possible geological disaster events subsequently, the server also determines the deformation components in the horizontal direction and the height direction here. In addition, in order to improve the effectiveness of subsequent danger warnings, the server in this embodiment also predicts the disaster-affected coverage area, which is calculated by combining the initial coverage area delimited by the initial position information of the reference tags and the current coverage area delimited by the tag position information (i.e., the current position information) of the reference tags, and the first deformation component and the second deformation component.

[0064] It can be seen that in this example, the server calculates the tag displacement amount of each positioning tag according to the tag position information and the initial position information of the positioning tags on both sides of the target highway section respectively, and then filters out the reference tags to determine the deformation information on the corresponding side, specifically including the predicted disaster-affected coverage area, the overall deformation amount, and the deformation components in the horizontal direction and the height direction. The server executes the next calculation by determining the tags with tag displacement amounts greater than the threshold, improving the efficiency and accuracy of determining the surface deformation information, effectively filtering out the data of the positioning tags with small tag displacement amounts, and calculating various types of deformation information through the tag position information, improving the accuracy and practicality of subsequent execution of danger warning operations.

[0065] In a possible embodiment, determining the disaster-affected coverage area located within the target highway section according to the initial coverage area, the current coverage area, the first deformation component, and the second deformation component includes: determining a first interval distance in the horizontal direction and a second interval distance in the height direction according to the tag position information of the reference tags and the section position information of the target highway section; determining a first actual deformation component in the horizontal direction and a second actual deformation component in the height direction according to the initial coverage area and the current coverage area; determining a first ratio of the first actual deformation component to the first deformation component, and determining a second ratio of the second actual deformation component to the second deformation component; determining a horizontal derived distance by dividing the first interval distance by the first ratio, and determining a height derived distance by dividing the second interval distance by the second ratio; determining the disaster-affected coverage area according to the current coverage area, the horizontal derived distance, and the disaster-affected height distance.

[0066] Among them, by obtaining the monitored first deformation component and second deformation component, and determining the first ratio and second ratio with their corresponding actual displacement components (i.e., the first actual deformation component and second actual deformation component determined according to the initial coverage area and the current coverage area), the ratio is used for the numerical ratio of the actual deformation component to the reference deformation component of the monitored surface deformation amount under actual geological changes. Based on this, the actual horizontal derivative distance and height derivative distance corresponding to the first interval distance in the horizontal direction and the second interval distance in the height direction are determined, and then combined with the current coverage area determined by the current position information, the affected coverage area when the geological disaster event actually spreads to the target highway section is calculated.

[0067] Exemplarily, please refer to Figure 4 , Figure 4 which is a schematic diagram of a scenario for determining the affected coverage area provided by an embodiment of the present application. As Figure 4 shown, the highway operation platform is equipped with a server in the highway operation system, and the display screen of the highway operation platform will display the associated data in the data processing executed by the server. As Figure 4 shown, the display screen of the highway operation platform includes the system time in the lower right corner, the name and number of the highway, as well as the first collection period and the second collection period. In addition, the display screen also includes a line graph of the relationship between the overall deformation amount on the first side and the collection time, and the location of the target highway section, so as to facilitate relevant staff to view. In addition, the display screen mainly presents that when the server determines that a possible geological disaster event is detected in the slope area on the first side of the target highway section, the server will predict the affected coverage area in the target highway section that may be affected by the geological disaster event during the process of calculating the first deformation information on the first side. The initial coverage area is determined according to the initial position information of the first label 1, the first label 2, and the first label 3, and the current coverage area is determined according to the current position information (i.e., the label position information) of the first label 1, the first label 2, and the first label 3. Then, by combining the first deformation component and the second deformation component through the above calculation process, the affected coverage area in the target highway section is predicted, and then the location and range of the affected coverage area in the target highway section are determined.

[0068] It can be seen that in this embodiment, by the initial coverage area, the current coverage area, the first deformation component, and the second deformation component, the affected coverage area when the geological disaster event actually spreads to the target highway section is predicted, which improves the flexibility and practicality of the server in executing data processing and the comprehensiveness of executing the danger warning operation.

[0069] Step S205, perform a danger warning operation adapted to the surface deformation information.

[0070] Among them, in this step, if the surface deformation information indicates that there is no geological disaster event in the target highway section, there is no need to perform a danger warning operation. If the surface deformation information indicates that there is a geological disaster event in the target highway section, an appropriate danger warning operation needs to be performed.

[0071] In a possible embodiment, performing a danger warning operation adapted to the surface deformation information includes: obtaining the regional geological information of the target highway section, historical weather data and historical deformation information within a preset time period; determining the deformation trend information according to the historical deformation information; according to the regional geological information, historical weather data and deformation trend information, determining a second deformation quantity threshold corresponding to the first side and a third deformation quantity threshold corresponding to the second side, both the second deformation quantity threshold and the third deformation quantity threshold are greater than the first deformation quantity threshold; if the overall deformation quantity in the first deformation information is greater than or equal to the second deformation quantity threshold, and / or, the overall deformation quantity in the second deformation information is greater than or equal to the third deformation quantity threshold, then determining the corresponding first side and / or second side as the high-risk side; and, according to the first deformation component and the second deformation component of the high-risk side, determining the disaster type corresponding to the geological disaster event; performing a danger warning operation according to the disaster type and the affected coverage area corresponding to the high-risk side.

[0072] Among them, the historical deformation information includes a plurality of surface deformation information determined by the second acquisition cycle completed within a preset time period, and the deformation trend information is used to characterize the corresponding relationship between the deformation rates and the acquisition times corresponding to the first side and the second side respectively.

[0073] Among them, by calculating the deformation trend information of the surface deformation corresponding to the first side and the second side of the target highway section, as well as the regional geological information and historical weather data, the second deformation quantity threshold and the third deformation quantity threshold of the surface on both sides adapted to the target highway section are determined. Only when the overall deformation quantity of the first deformation information is greater than or equal to the second deformation quantity threshold and / or, the overall deformation quantity in the second deformation information is greater than or equal to the third deformation quantity threshold, that is, when one side of the two sides is a high-risk side and there is a danger of a geological disaster event occurring, will the server perform the subsequent danger warning operation. That is, if the overall deformation quantity in the first deformation information is less than the second deformation quantity threshold and the overall deformation quantity in the second deformation information is less than the third deformation quantity threshold, no danger warning operation will be performed to avoid frequently triggering the danger warning operation and affecting the normal passage of vehicles on the target highway section, causing unnecessary panic.

[0074] Among them, the types of geological disaster events that may occur on highways can include landslides, collapses (or cave - ins), debris flows, ground subsidence, etc. By analyzing the magnitude relationship between the surface deformation components in the horizontal and height directions of the surface deformation generated during historical geological disaster events and the possible ranges of the corresponding data, for example, for a mountaintop landslide, the surface deformation components in both the horizontal and height directions are large, for a collapse, the surface deformation component in the horizontal direction is small, while the surface deformation component in the height direction is large. Furthermore, combined with the currently determined first deformation component and second deformation component, the type of the geological disaster event that may occur in the current monitoring is determined.

[0075] It can be seen that in this example, the server determines the deformation amount thresholds for the first side and the second side of the target highway section respectively, and then determines the high - risk side and the type of geological disaster event that may occur, and then performs an adapted danger warning operation, improving the accuracy and effectiveness of the server's danger warning operation.

[0076] In a possible embodiment, determining the second deformation amount threshold corresponding to the first side and the third deformation amount threshold corresponding to the second side according to regional geological information, historical weather data, and deformation trend information includes: determining the rock and soil properties and rock and soil types according to regional geological information; determining the total rainfall, total irradiation duration, and average irradiation intensity between two consecutive collection times according to historical weather data; determining the reference water storage according to the total rainfall and permeability, and determining the evaporation amount according to the total irradiation duration, average irradiation intensity, and evaporation rate; and determining the water storage increment corresponding to two consecutive collection times; predicting the first soil saturation at the current moment corresponding to the first side and the second soil saturation at the current moment corresponding to the second side according to the deformation trend information and the water storage increment; determining the second deformation amount threshold and the third deformation amount threshold according to a preset set of numerical relationships associated with the rock and soil types, the first soil saturation, and the second soil saturation.

[0077] Among them, the rock and soil properties include permeability and evaporation rate, the water storage increment is determined by the reference water storage and evaporation amount between the corresponding two consecutive collection times, the set of numerical relationships is used to indicate the corresponding relationship between multiple reference soil saturations and multiple reference deformation amount thresholds, and there is a negative correlation between the soil saturation and the reference deformation amount threshold.

[0078] Among them, by combining historical weather data with the regional geological information on both sides of the target highway section, the server can estimate the water storage increment absorbed by the ground surface on both sides within any two consecutive acquisition times, and then, combined with the deformation trend information, the first soil saturation corresponding to the first side and the second soil saturation corresponding to the second side at the current moment can be predicted. Among them, the higher the soil saturation, the higher the deformation amount (higher deformation rate) affected by the same water storage increment. After that, based on the preset set of numerical relationships associated with the rock and soil types, the server can determine the second deformation amount threshold and the third deformation amount threshold corresponding to possible geological disaster events for different soil saturations. It should be noted that the higher the soil saturation, the smaller the soil suction, and the relatively smaller the deformation amount threshold; the lower the soil saturation, the greater the soil suction, and the relatively larger the deformation amount threshold; there is a certain difference between the second deformation amount threshold and the third deformation amount threshold and the ultimate ground surface deformation amount corresponding to the actual soil saturation, but the difference should not be too large to avoid causing a greater impact on the traffic of vehicles on the target highway section due to premature danger warning operations, that is, affecting the normal use of the target highway section.

[0079] It can be seen that in this example, the server determines the soil saturations of the first side and the second side by calculating the water storage increment and the deformation trend information of the ground surface on both sides corresponding to two consecutive acquisition times, and then determines the deformation amount threshold for each side, improving the flexibility of the server to perform data processing and the accuracy of warning of geological disaster events.

[0080] In a possible embodiment, the highway operation system further includes an alarm device; according to the disaster type and the disaster-affected coverage area corresponding to the high-risk side, perform a danger warning operation, including: obtaining a preset set of protection strategies; determining the corresponding reference protection strategy as the target protection strategy according to the disaster type; sending a protection request message carrying the target protection strategy for the high-risk side to the terminal device; and, according to the disaster-affected coverage area and the lane information of the target highway section, determining the passable lanes and the lane directions corresponding to the passable lanes; according to the lane directions, controlling the alarm devices with a distance greater than the preset alarm distance from the target highway section in the opposite direction of the lane directions to perform the alarm operation corresponding to the passable lanes; and, determining the cycle shortening time according to the coverage area of the disaster-affected coverage area to reduce the cycle duration corresponding to the second acquisition cycle.

[0081] Among them, the set of protection strategies includes the corresponding relationship between the disaster type and the reference protection strategy, and the alarm operation is used to prompt the vehicle driver to change lanes to the passable lanes in advance.

[0082] Among them, the types of geological disaster events that may occur on highways can include landslides, collapses (or cave - ins), debris flows, ground collapses, etc. The server determines the target protection strategy based on the types of disasters determined on the first side and the second side of the target highway section, and then sends the target protection strategy for the corresponding high - risk side to the terminal device through a protection request message so that the staff can execute the corresponding protection strategy for the high - risk side corresponding to the target highway section, achieving effective prevention of possible disaster types.

[0083] Exemplarily, the protection strategy set contains the reference protection strategies corresponding to each of the above - mentioned disaster types, which can be specifically the following: 1. The reference protection strategy corresponding to a landslide includes engineering measures: taking engineering means such as drainage, weight reduction, and counter - pressure to enhance the slope stability; vegetation restoration: by means such as afforestation to increase the slope vegetation coverage rate and enhance the soil consolidation force. 2. The reference protection strategy corresponding to a collapse includes slope cutting and load reduction: cutting the slope of the potential collapse body to reduce its potential energy; anchoring and reinforcement: using engineering means such as anchor rods and cables to reinforce the dangerous rock mass; blocking measures: building rock - blocking walls, rock - falling platforms, etc. to intercept the falling debris. 3. The reference protection strategy corresponding to a debris flow includes a combination of biological and engineering measures: by means such as afforestation and building sediment - retaining dams to reduce the debris source and energy of the debris flow; adjusting the flow path: using engineering measures such as drainage ditches and sedimentation ponds to adjust the flow path and deposition site of the debris flow. 4. The reference protection strategy corresponding to a ground collapse includes engineering measures: taking engineering means such as drilling grouting and jet grouting reinforcement to reinforce the potential collapse area.

[0084] Further, the lane information specifically includes the number of lanes, the range of each lane, and the lane direction. Based on the predicted disaster - affected coverage area and lane information, the server can determine the lanes that will not be affected by the disaster (i.e., passable lanes) and the lane directions of the passable lanes. By controlling the alarm devices at a relatively long distance in the opposite direction of the lane direction to perform alarm operations, vehicles heading towards the target highway section can effectively and timely change lanes to the passable lanes to avoid in advance the disaster - affected coverage area affected by the occurrence of geological disaster events, effectively reducing casualties and property damage. In addition, the server can also improve the monitoring frequency of surface deformation by reducing the cycle duration corresponding to the second collection cycle, so as to achieve the effect of timely notifying the terminal device and regional warning when a geological disaster occurs.

[0085] Exemplarily, please refer to Figure 5 , Figure 5 is a schematic diagram of a scenario where the server in an embodiment of the present application performs a danger warning operation. As Figure 5As shown, the types of alarm devices include warning signs and horn devices set on highways. The server determines that the geological disaster event that may occur is a debris flow. The server determines the reference protection strategy corresponding to the debris flow as the target protection strategy by querying the protection strategy set, and then sends the target protection strategy to the staff carrying the terminal device for execution to prevent possible geological disaster events and reduce the impact on the target highway section due to the disaster. Also, according to the disaster-affected coverage area, the server can determine that only the first lane on the right is the passable lane, and then perform the alarm operation corresponding to the passable lane, control the horn device to broadcast a message to instruct the driver to change lanes to the first lane on the right, and display the passable lane and the non-passable lane on the warning sign, and display relevant copy for reminder. The content of the copy is "Debris flow may occur in the left two lanes 500 meters ahead. Please change lanes to the first lane on the right."

[0086] It can be seen that in this example, the server realizes notifying the staff carrying the terminal device to execute the corresponding protection strategy by determining the disaster type and the disaster-affected coverage area corresponding to the high-risk side, and enabling the vehicle to effectively bypass the disaster-affected coverage area, improving the practicality and diversity of the server's execution of danger warnings, as well as the accuracy and timeliness of the execution of danger warnings and alarm operations.

[0087] It can be seen that Figure 2 is a schematic flowchart of a method for danger warning based on a highway section provided by an embodiment of the present application. The server determines the target highway section by monitoring the radar images collected by the radar device, and performs a danger warning operation adapted to the surface deformation information based on the positioning tag for the target highway section, improving the flexibility and efficiency of the server's data processing, as well as the accuracy of the danger warning.
