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

[0034] Based on this, an embodiment of the present application provides a danger warning method based on a highway section, and the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0035] See also Figure 2 , Figure 2 1 is a flow chart of a danger warning method based on a highway section provided in an embodiment of the present application. The method is applied to a server 110 in a highway operation system 100. The highway operation system 100 also includes a positioning tag 120, a radar device 130 and a terminal device 140. The radar device 130 is used to collect radar images for a target area. The terminal device 140 is carried by a staff member in the target area. The method includes:

[0036] Step S201: Acquire a radar image collected by a radar device according to a first collection cycle.

[0037] Among them, this step can use the Interferometric Synthetic Aperture Radar (InSAR), which is specifically a remote sensing technology that uses the surface backscatter echo signal obtained by the synthetic aperture radar for interference processing to extract the three-dimensional information and high-precision deformation information of the surface. The specific steps of the radar equipment to collect radar images are: the radar equipment is carried by a satellite or an aircraft, and then the radar equipment transmits microwave pulses to the ground and receives echoes, thereby generating multiple high-resolution radar images corresponding to the target area in different time periods (the radar system has a built-in clock corresponding to the first acquisition cycle, and each first acquisition cycle performs a radar image acquisition operation once), and the phase difference between two or more radar images obtained from slightly different positions is used to accurately measure the surface deformation amount occurring at multiple observation positions on the surface of the target area.

[0038] Step S202: If the radar image determines that the surface deformation amount of any 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 in the target area is less than a preset distance, then the target position mapped on the center line of the road with the shortest distance is taken as the center, and the highway with a preset monitoring length is determined as the target highway section.

[0039] Among them, when the radar image determines that the surface deformation variable of any observation position is greater than the first deformation variable threshold, and the shortest distance between the observation position and the middle line of the road is less than the preset distance, this indicates that the surface change of the observation position has a trend of evolving into a geological disaster event, and the observation position is close to the highway, which means that if a geological disaster event occurs there, the highway will be affected, resulting in vehicles being unable to pass or causing traffic accidents. Therefore, based on the observation position, a section of the highway is determined as the target highway section, and further and more accurate surface deformation monitoring is performed on the target highway section to ensure that the occurrence of geological disaster events can be discovered in time, and early warnings are made to avoid large losses to vehicles or highway sections, and protect traffic safety and personnel safety. Among them, the preset monitoring length can be determined based on the shortest distance, for example, the longer the shortest distance, the shorter the preset monitoring length, and vice versa, the shorter the shortest distance, the longer the preset monitoring length; in this way, the number and range of subsequent placement of positioning tags can be effectively reduced, and the consumption of personnel and resources and the amount of data that the server needs to perform data processing can be reduced. The minimum length of the preset monitoring length can be determined according to the specific surface deformation amount of the observation position, and the minimum length of the preset monitoring length is proportional to the surface deformation amount.

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

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

[0042] In one possible embodiment, label setting information corresponding to the target expressway section is determined based on the radar image, including: if there is no slope area on the current side of the target expressway section being processed, then the area along the line within a preset interval distance from the guardrail on the current side of the target expressway section is determined as the monitoring area; and according to the preset label interval distance, the setting position of the positioning label in the monitoring area is determined; if there is a slope area on the current side of the target expressway section being processed, then the geological structure characteristics and slope deformation characteristics corresponding to the slope area are determined based on the latest acquired radar image; based on the geological structure characteristics and the slope deformation characteristics, multiple monitoring areas in the slope area and the monitoring level corresponding to each monitoring area are determined; according to the preset label density corresponding to each monitoring level, the setting position of the positioning label in the corresponding monitoring area is determined.

[0043] Among them, the preset label density is positively correlated with the monitoring level.

[0044] Wherein, the target expressway section has two sides, and the server executes different strategies to determine the monitoring area of ​​the positioning tag and the number of positioning tags to be deployed in the monitoring area according to whether there is a slope area on the current side being processed. Wherein, if there is no slope area on the current side (which can be a mountain), the area along the line with a preset spacing distance from the guardrail is determined as the monitoring area, that is, the positioning tags are laid along the target expressway section, and the spacing distance between any two adjacent positioning tags is the same, which is the label spacing distance. The label spacing distance should be moderate, and the label spacing distance can be determined according to the geological environment of the target expressway section to avoid the inability to effectively monitor the surface deformation due to too long spacing, and further danger warning. If there is a slope area on the current side, the radar image is used to divide the slope area into multiple monitoring areas according to the geological structure characteristics and slope deformation characteristics of the slope area, and the monitoring level of each monitoring area. The monitoring level can be understood as the danger level of the area, which is used to characterize the probability of collapse, landslide and other events in the monitoring area. By configuring more positioning tags (higher preset tag density) for monitoring areas with higher monitoring levels, the accuracy and precision of monitoring surface deformation can be improved, thereby improving the accuracy and timeliness of danger warnings.

[0045] For example, see Figure 3 , Figure 3 Schematic diagram of a scenario for positioning tags set for a target highway section provided by an embodiment of the present application. Figure 3 As shown, the type of terminal device carried by the staff can be a square dial watch or a round dial watch. After the server determines that the label setting information corresponding to the target highway section is completed, the server will send the label setting information to the terminal device to display the corresponding label setting information. Among them, the content of the screen displayed by the smart watch is: 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 out the positioning tags in the non-slope area, the positioning tags are laid along the target highway section, and the interval distance between any two adjacent positioning tags is the same. When the server determines the label setting information for laying out the positioning tags 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 circle part in the middle slope area, and according to the monitoring level of each monitoring area, set positioning tags with different preset tag densities, Figure 3 From top to bottom, the first and second monitoring areas have the same monitoring level, and the corresponding label density is two, while the third monitoring area has a higher monitoring level, and its corresponding label density is four. Setting more positioning labels for monitoring areas with high monitoring levels can improve the accuracy and precision of monitoring surface deformation.

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

[0047] Step S204, after interacting with the terminal device to complete the tag setting operation based on the setting position, the tag position information collected by each positioning tag is obtained according to the second collection cycle to determine the surface deformation information.

[0048] The period length of the second collection period is shorter than the period length of the first collection period.

[0049] Among them, since the accuracy of the positioning tag collecting tag position information to determine the associated information of the surface deformation is significantly higher than the accuracy of determining the surface deformation by collecting radar images of the target area through radar equipment, the high-frequency collection of tag position information (that is, setting the cycle duration of the second collection cycle to be shorter than the cycle duration of the first collection cycle) can effectively improve the accuracy and timeliness of the server's danger warning for the target highway section, improve the practicality of the server, and reduce the impact of geological disasters on highways and moving vehicles.

[0050] Specifically, the specific steps for the server to interact with the terminal device to complete the label setting operation based on the setting location 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 locations of multiple positioning tags near the target highway section that needs to be deployed; 3. The staff deploys the positioning tags one by one through these setting locations; 4. The positioning tags calculate and record the label location information in real time; 5. After the staff has finished deploying the positioning tags, the terminal device sends a label setting response instruction to the server, and the label setting response instruction is used to indicate that the staff has completed the deployment of the positioning tags; 6. The server responds to the label setting response instruction to confirm that the label setting operation is completed.

[0051] Furthermore, the positioning tag can be set as an IoT communication beacon, and a positioning antenna can be set on the IoT communication beacon. The functions of the IoT communication beacon include: 1. Communication standard: The beacon is a communication standard that coordinates and integrates the operation of various parts of the communication system in accordance with certain technical specifications and protocol regulations to ensure accurate transmission and effective communication of information. This is an indispensable part of IoT communication and provides a basis for smooth communication between various devices and systems. 2. Ensure accurate transmission of information: By stipulating a unified information encoding and processing method, the beacon can ensure that the information is not distorted or misunderstood during transmission, thereby improving the reliability and accuracy of communication. 3. Promote interoperability: In a diversified IoT environment, devices that follow the same beacon can understand and communicate with each other, promoting interoperability between different systems and devices. Combining with positioning tags can improve positioning accuracy and reliability. The beacon provides a stable communication environment and unified standards for positioning tags, reducing errors and interference in the positioning process, thereby improving 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: positioning tags and solar panels, the solar panels can power the positioning tags, and the positioning tags are installed on the ground; the second installation method is: installation at the street light position of the target highway section, directly installed 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 the Internet of Things communication is used to transmit signals to the outside, and a gateway is installed on the lamp post every 1 kilometer to receive the Internet of Things communication signal.

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

[0053] The initial position information is the earliest tag position information collected by the corresponding positioning tag.

[0054] Among them, in order to improve the accuracy of monitoring surface deformation, the server obtains the earliest collection time of each positioning tag corresponding to the tag location information (i.e., initial location information) located on the first side or the second side of the target expressway section, so as to divide the positioning tags into first tags and second tags. At the end of each second collection cycle, the surface deformation information of the first side of the target expressway section is determined according to the tag location information of the first tag on the first side, and the surface deformation information of the second side of the target expressway section is determined according to the tag location information of the second tag on the second side. In the subsequent data processing process, the target expressway section is also monitored and warned on both sides of the road center line, so as to improve the accuracy of the 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 distinguishes each positioning tag into a first tag located on the first side and a second tag on the second side through the initial position information of each positioning tag, and then determines the first deformation information of the first side of the target highway section for the first tag, and determines the second deformation information of the second side of the target highway section for the second tag, thereby 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 according to the tag position information and the corresponding initial position information corresponding to the first tag obtained in the current period, including: determining the tag displacement and the tag displacement direction according to the tag position information and the corresponding initial position information of each first tag; determining the first tag whose corresponding tag displacement is greater than the preset displacement as the reference tag; determining the overall deformation of the first side, as well as the first deformation component of the overall deformation in the horizontal direction and the second deformation component of the overall deformation in the height direction according to the tag displacement 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 current period of the reference tag; determining the affected coverage area located in the target expressway section according to the initial coverage area, the current coverage area, the first deformation component and the second deformation component; determining the first deformation information according to the affected coverage area, the overall deformation, the first deformation component and the second deformation component.

[0057] Among them, this embodiment is a specific implementation method in which the server determines 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 method in which the server determines the second deformation information based on the tag position information and the initial position information of the second tag is identical thereto, and the content type in the first deformation information and the second deformation information is the same, and only the specific numerical value of each data item differs.

[0058] The calculation process of 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] Assuming that the initial position coordinates (i.e., initial position information) are P0 (x0, y0, z0), and the current position coordinates (i.e., tag position information) are P1 (x1, y1, z1), the total displacement d can be obtained by the following formula:

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

[0061] The displacement direction of the tag is represented by the displacement vector ΔP, which can be obtained by 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, the server selects the reference tags with large deformation displacement through the preset displacement, and calculates the overall deformation of the first side of the target expressway section through the tag displacement of the reference tag and its corresponding tag displacement direction, and in order to subsequently determine the disaster type of the possible geological disaster event, the server here will also determine the deformation components in the horizontal direction and the height direction. And, in order to improve the effectiveness of subsequent danger warnings, in this embodiment, the server will also predict the disaster-affected coverage area, which is the initial coverage area defined by the initial position information of the reference tag and the current coverage area defined by the tag position information (i.e., current position information) of the reference tag, combined with the first deformation component and the second deformation component.

[0064] It can be seen that in this example, the server calculates the label displacement of each positioning tag according to the label position information and initial position information of the positioning tags on both sides of the target expressway section, and then screens out the reference tags to determine the deformation information of the corresponding side, including the predicted disaster-stricken coverage area, the overall deformation amount, and the deformation components in the horizontal and height directions. The server performs the next step of calculation by determining the tags with label displacements greater than the threshold, thereby improving the efficiency and accuracy of determining the surface deformation information, effectively screening out the data of positioning tags with smaller label displacements, and calculating various types of deformation information through label position information, thereby improving the accuracy and practicality of subsequent danger warning operations.

[0065] In one possible embodiment, the affected coverage area within the target highway section is determined based on the initial coverage area, the current coverage area, the first deformation component, and the second deformation component, including: determining the first spacing distance in the horizontal direction and the second spacing distance in the height direction based on the tag position information of the reference tag and the section position information of the target highway section; determining the first actual deformation component in the horizontal direction and the second actual deformation component in the height direction based on 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 derivative distance based on the first spacing distance divided by the first ratio, and determining a height derivative distance based on the second spacing distance divided by the second ratio; determining the affected coverage area based on the current coverage area, the horizontal derivative distance, and the affected height distance.

[0066] Among them, by obtaining the monitored first deformation component and the second deformation component, and the actual displacement components corresponding to them (that is, the first actual deformation component and the second actual deformation component determined according to the initial coverage area and the current coverage area), a first ratio and a second ratio are determined. The ratio is used for the numerical ratio of the actual deformation component under actual geological changes to the reference deformation component of the monitored surface deformation. Based on this, the actual horizontal derivative distance and the height derivative distance corresponding to the remaining 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 disaster-stricken coverage area when the geological disaster event is actually derived to the target highway section is calculated.

[0067] For example, see Figure 4 , Figure 4 Schematic diagram of a scenario for determining a disaster-affected coverage area provided by an embodiment of the present application. Figure 4 As shown, the high-speed operation platform is equipped with a server in the high-speed operation system, and the display screen of the high-speed operation platform will display the related data in the data processing performed by the server. Figure 4 The display screen of the high-speed operation platform shown includes the system time in the lower right corner, the name and number of the highway, and the first acquisition cycle and the second acquisition cycle. In addition, the display screen also includes a line graph of the relationship between the overall deformation amount of the first side and the acquisition time, as well as the location of the target highway section, so that relevant staff can view it. In addition, the display screen also focuses on presenting that when the server determines that the slope area on the first side of the target highway section monitors a possible geological disaster event, the server will predict the disaster-affected coverage area in the target highway section that may be affected by the geological disaster event during the calculation of the first deformation information of 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., label position information) of the first label 1, the first label 2 and the first label 3, and then the first deformation component and the second deformation component are combined through the above calculation process to predict the disaster-affected coverage area in the target highway section, and then determine the location and range of the disaster-affected coverage area in the target highway section.

[0068] It can be seen that in this embodiment, the disaster-stricken coverage area when the geological disaster event actually derives to the target highway section is predicted through the initial coverage area and the current coverage area as well as the first deformation component and the second deformation component, thereby improving the flexibility and practicality of the server in executing data processing and improving the comprehensiveness of executing danger warning operations.

[0069] Step S205, executing 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 on 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 on the target highway section, an adapted danger warning operation needs to be performed.

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

[0072] The historical deformation information includes a plurality of surface deformation information determined by a second acquisition cycle completed in a preset time period, and the deformation trend information is used to characterize the corresponding relationship between the deformation rate and acquisition time 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 expressway section, as well as the regional geological information and historical weather data, the second deformation value threshold and the third deformation value threshold suitable for the surface on both sides of the target expressway section are determined. Only when the overall deformation value of the first deformation information is greater than or equal to the second deformation value threshold and / or the overall deformation value in the second deformation information is greater than or equal to the third deformation value threshold, that is, when one of the two sides is a high-risk side and there is a danger of a geological disaster, the server will perform the next danger warning operation, that is, if the overall deformation value in the first deformation information is less than the second deformation value threshold, and the overall deformation value in the second deformation information is less than the third deformation value threshold, the danger warning operation will not be performed, so as to avoid frequent triggering of the danger warning operation and affecting the normal passage of vehicles on the target expressway section, causing unnecessary panic.

[0074] Among them, the types of geological disasters that may occur on highways may include landslides, collapses (or collapses), mudslides, ground subsidence, etc. By analyzing the size relationship between the surface deformation components in the horizontal and height directions of the surface deformations generated when geological disasters occurred in history and the possible range of corresponding data, for example, the surface deformation components in the horizontal and height directions corresponding to the mountaintop landslide are large, the surface deformation component in the horizontal direction corresponding to the collapse is small, and the surface deformation component in the height direction is large. Then, the type of the geological disaster event that may occur in the current monitoring is determined in combination with the currently determined first deformation component and the second deformation component.

[0075] It can be seen that in this example, the server determines the deformation thresholds for the first side and the second side of the target highway section respectively, and then determines the high-risk side and disaster type where geological disasters may occur, and then performs adaptive danger warning operations to improve the accuracy and effectiveness of the server's danger warning operations.

[0076] In a possible embodiment, a second deformation value threshold corresponding to the first side and a third deformation value threshold corresponding to the second side are determined based on regional geological information, historical weather data and deformation trend information, including: determining geotechnical properties and geotechnical types based on regional geological information; determining the total rainfall, total illumination time and average illumination intensity between two consecutive acquisition times based on historical weather data; determining a reference water storage capacity based on total rainfall and permeability, and determining evaporation based on total illumination time, average illumination intensity and evaporation rate; and determining a water storage increment corresponding to two consecutive acquisition times; predicting a first soil saturation corresponding to the first side at the current moment and a second soil saturation corresponding to the second side at the current moment based on deformation trend information and water storage increment; and determining a second deformation value threshold and a third deformation value threshold based on a preset set of numerical relationships associated with geotechnical types, the first soil saturation and the second soil saturation.

[0077] Among them, the geotechnical properties include permeability and evaporation rate, the water storage increment is determined by the reference water storage and evaporation between two corresponding consecutive acquisition times, and the numerical relationship set is used to indicate the correspondence between multiple reference soil saturations and multiple reference deformation thresholds. The soil saturation and the reference deformation threshold are negatively correlated.

[0078] Among them, by combining historical weather data with regional geological information on both sides of the target highway section, the server can estimate the water storage increment absorbed by the surface on both sides during 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 increased by the same water storage increment (the higher the deformation rate). After that, the server can determine the second deformation amount threshold and the third deformation amount threshold corresponding to different soil saturations that may cause geological disasters according to the preset numerical relationship set associated with the rock and soil type. It should be noted that the higher the soil saturation, the smaller the soil suction, and the deformation amount threshold should be relatively small; the lower the soil saturation, the greater the soil suction, and the deformation amount threshold should be relatively large; there is a certain difference between the second deformation amount threshold and the third deformation amount threshold and the limit surface deformation amount corresponding to the actual soil saturation, but the difference is not easy to be too large, so as to avoid premature danger warning operations from causing a large impact on the passage of vehicles on the target highway section, 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 saturation on the first side and the second side by calculating the water storage increment and deformation trend information of the surface on both sides corresponding to two consecutive acquisition times, and then determines the deformation threshold on each side, thereby improving the flexibility of the server in executing data processing and the accuracy of warning of geological disaster events.

[0080] In one possible embodiment, the highway operation system also includes an alarm device; according to the disaster type and the disaster-stricken coverage area corresponding to the high-risk side, a danger warning operation is performed, 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 lane information of the disaster-stricken coverage area and the target highway section, determining the passable lane and the lane direction corresponding to the passable lane; according to the lane direction, controlling the alarm device in the opposite direction of the lane direction whose interval distance from the target highway section is greater than the preset alarm distance to perform the alarm operation corresponding to the passable lane; and, determining the cycle shortening time according to the coverage area of ​​the disaster-stricken coverage area to reduce the cycle duration corresponding to the second collection cycle.

[0081] Among them, the protection strategy set includes the correspondence between disaster types and reference protection strategies, and the alarm operation is used to prompt the vehicle driver to change lanes to a passable lane in advance.

[0082] Among them, the disaster types of geological disaster events that may occur on the highway may include landslides, collapses (or collapses), mudslides, ground collapses, etc. The server determines the target protection strategy based on the disaster types determined by the first side and the second side of the target highway section, and then sends the target protection strategy corresponding to the high-risk side to the terminal device through a protection request message so that the staff can execute the corresponding protection strategy on the high-risk side corresponding to the target highway section, so as to effectively prevent the possible disaster types.

[0083] Exemplarily, the reference protection strategies corresponding to the above-mentioned disaster types included in the protection strategy set may be as follows: 1. Reference protection strategies corresponding to landslides include engineering measures: adopting engineering means such as drainage, weight reduction, and counterpressure to enhance slope stability; vegetation restoration: increasing slope vegetation coverage and enhancing soil consolidation through afforestation and other means. 2. Reference protection strategies corresponding to collapse include slope cutting and load reduction: cutting the slope of potential collapse bodies to reduce their potential energy; anchoring reinforcement: using engineering means such as anchor rods and anchor cables to reinforce dangerous rock bodies; blocking measures: building rock-blocking walls, rockfall platforms, etc. to intercept collapse objects. 3. Reference protection strategies corresponding to debris flows include a combination of biological and engineering measures: reducing the source and energy of debris flows through afforestation, building sand dams, etc.; adjusting the flow path: using engineering measures such as drainage ditches and siltation sites to adjust the flow path and siltation sites of debris flows. 4. The reference protection strategy corresponding to ground collapse includes engineering measures: adopting engineering means such as drilling grouting and rotary jet reinforcement to reinforce the potential collapse area.

[0084] Furthermore, 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), as well as the lane directions of passable lanes. By controlling the alarm operation of the longer-distance alarm device in the opposite direction of the lane direction, vehicles heading to the target highway section can effectively and timely change lanes to passable lanes, so as to avoid the disaster-affected coverage area affected by the geological disaster event in advance, and effectively reduce casualties and property damage. In addition, the server can also increase the monitoring frequency of surface deformation by reducing the cycle length corresponding to the second acquisition cycle, so as to achieve the effect of timely notification of terminal equipment and regional early warning when a geological disaster occurs.

[0085] For example, see Figure 5 , Figure 5 Schematic diagram of a scenario in which a server performs a danger warning operation provided by an embodiment of the present application. Figure 5As shown, the types of alarm equipment include warning lights and horn equipment installed on the highway. The server determines that the possible geological disaster event is a mudslide. The server determines the reference protection strategy corresponding to the mudslide 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 to prevent possible geological disaster events and reduce the impact of the disaster on the target highway section. In addition, according to the disaster coverage area, the server can determine that only the first lane on the right is a 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 lanes and impassable lanes on the warning light board, and display relevant text for prompting, the text content is "mudslides may occur in the two left 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 determines the disaster type and the disaster-stricken coverage area corresponding to the high-risk side to notify the staff carrying terminal equipment to implement corresponding protection strategies, and enables vehicles to effectively bypass the disaster-stricken coverage area, thereby improving the practicality and diversity of the server's execution of danger warnings, as well as the accuracy and timeliness of danger warnings and alarm operations.

[0087] visible, Figure 2 It is a flow chart of a danger warning method based on a highway section provided in an embodiment of the present application. The server determines the target highway section by acquiring radar image monitoring collected by the radar equipment, and monitors the surface deformation of the target highway section based on the positioning tag to perform danger warning operations adapted to the surface deformation information, thereby improving the flexibility and efficiency of the server in executing data processing, and improving the accuracy of danger warning.
