Background Art

[0002] The mainstream navigation systems in the market can provide a relatively accurate forecast of the congestion ahead of the vehicle.

[0027] The following is a description of the implementation of the present application by specific specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] It should be noted that the steps in the claims and description of the present application may be executed substantially in parallel or in reverse order under appropriate circumstances, depending on the functions involved.

[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] An embodiment of the present application provides a method for real-time identification and early warning of road geological disasters based on abnormal changes in elevation displacement trajectory of navigation software, referring to Figure 1 , Figure 1 A flowchart of a method for real-time identification and early warning of road geological disasters based on abnormal changes in the elevation displacement trajectory of navigation software is provided in at least one embodiment of the present application. It should be understood that the method may also include additional boxes not shown and / or the boxes shown may be omitted, and the scope of the present application is not limited in this respect.

[0031] In step 101, the vehicle's travel elevation and displacement real-time trajectory are monitored, and the vehicle's travel elevation data and displacement real-time trajectory data are acquired in real time.

[0032] At step 102, based on the acquired vehicle travel elevation data and displacement real-time trajectory data, when it is determined that the vehicle elevation displacement trajectory is abnormal, the type of geological disaster that has occurred is determined through a collision trajectory model and a parabolic trajectory model.

[0033] At step 103, the abnormal change of the vehicle's elevation displacement trajectory, the type of geological disaster and the corresponding warning information are transmitted in real time to the vehicle behind the vehicle.

[0034] Specifically, vehicle elevation monitoring: using the vehicle's GPS or Beidou satellite positioning system combined with map data to record and calculate the elevation changes of the vehicle in real time during driving. This is crucial for identifying abnormal changes in the vertical direction of the road (such as landslides and road subsidence). Real-time displacement trajectory monitoring: combining the vehicle's speed, acceleration sensor and GPS trajectory to analyze subtle changes in the vehicle's driving path, especially deviations in unexpected directions, which helps capture abnormalities in the horizontal direction of the road (such as road blockages or deviations caused by landslides and mudslides).

[0035] In some embodiments, the vehicle driving elevation data and displacement real-time trajectory data are obtained from navigation software.

[0036] In some embodiments, after transmitting the warning information to the vehicle behind the vehicle in real time, the following steps are included:

[0037] The following vehicle is reminded through the buzzer alarm mode of the navigation device and the red emergency stop signal on the navigation device screen, and the geological disaster analysis results are fed back to the local emergency management department in real time.

[0038] In some embodiments, when the vehicle elevation displacement trajectory is a collision trajectory model, the type of geological disaster is determined to be a landslide, collapse, or mudslide occurring above the road.

[0039] In some embodiments, when the vehicle elevation displacement trajectory is a parabolic trajectory model, the type of geological disaster is determined to be the collapse of the road itself or the collapse or landslide under the road.

[0040] Specifically, the type of geological disaster is analyzed in real time through the abnormal patterns and characteristics of the displacement and elevation trajectory of the vehicle that has had an accident (such as the collision trajectory model - inverting the types of geological disasters such as landslides, collapses, and mudslides occurring above the road; the parabolic trajectory model - inverting the collapse of the road itself, or the types of geological disasters such as collapses and landslides occurring below the road); the abnormal changes of the leading vehicle, the analyzed geological disaster types and early warnings are used to force the rear vehicles to be reminded in real time, and the following vehicles are prevented from repeating the same mistakes through the buzzing alarm mode of the navigation device and the red emergency stop signal on the navigation device screen; and the results of the geological disaster analysis are fed back to the local emergency management department in real time to promptly initiate the disaster prevention, mitigation and rescue plan.

[0042] The data resource layer is used to build an integrated data center that can open and share data with navigation software, and to construct a professional monitoring module, which is used for real-time trajectory monitoring of vehicle driving elevation and displacement.

[0043] The business application layer includes a real-time road geological disaster identification module and a refined risk real-time warning module. The real-time road geological disaster identification module is used to determine the type of geological disaster that has occurred through a collision trajectory model and a parabolic trajectory model when the vehicle's elevation displacement trajectory changes abnormally based on the vehicle's driving elevation data and real-time displacement trajectory data obtained by the professional monitoring module; the refined risk real-time warning module is used to transmit the vehicle's elevation displacement trajectory changes, the geological disaster type and the corresponding warning information to the vehicle behind the vehicle in real time.

[0044] In some embodiments, it also includes: forcibly reminding the rear vehicles through the buzzer alarm mode of the navigation device, the red emergency stop signal on the navigation device screen, etc., and feeding back the results of the geological disaster analysis to the local emergency management department in real time, so as to promptly initiate the disaster prevention, mitigation and rescue plan.

[0045] In some embodiments, the road geological disaster real-time identification module is used to analyze and identify the type of geological disasters in real time, and the specific methods include:

[0046] When the vehicle elevation displacement trajectory is a collision trajectory model, the geological disaster type is determined to be a landslide, collapse, mud-rock flow or other geological disaster types occurring above the road.

[0047] In some embodiments, the road geological disaster real-time identification module is used to analyze and identify the type of geological disasters in real time, and the specific method also includes:

[0048] When the vehicle elevation displacement trajectory is a parabolic trajectory model, the geological disaster type is determined to be the collapse of the road itself or the collapse, landslide and other geological disaster types occurring under the road.

[0049] In some embodiments, the system is connected to an infrastructure layer, which is used to support the operation and services of the system, specifically including a 5G network, a navigation platform, a GIS platform, an Internet of Things platform, and a cloud computing platform.

[0050] Specifically, as the cornerstone of data transmission, 5G network provides low-latency, high-bandwidth communication capabilities, ensuring real-time transmission of vehicle driving data and rapid response of the system; the navigation platform provides vehicles with accurate positioning and navigation services, and at the same time serves as an important channel for the release of early warning information, ensuring that information can be accurately and promptly conveyed to drivers; GIS platform: Geographic Information System (GIS) is used to process and analyze geospatial data, providing the system with map display, spatial analysis and other functions to help users intuitively understand the location of the disaster and its surrounding environment; the Internet of Things platform connects various sensors and monitoring equipment to realize data collection, transmission and preliminary processing, and provide raw data support for upper-level applications; the cloud computing platform provides powerful computing power and data storage capabilities, supports large-scale data processing and complex algorithm operation, and ensures efficient and stable operation of the system.

[0053] The real-time identification and early warning system for road geological disasters based on abnormal changes in elevation displacement trajectory of navigation software provided by this application has the following advantages:

[0054] According to the user's elevation displacement change trajectory data collected by the user terminal, the user's current geological disaster type is automatically analyzed, and the geological disaster information and warning of the user's current location are transmitted to the rear vehicle in real time. The navigation device buzzer alarm mode and the red emergency stop signal on the navigation device screen are used to force the rear vehicle to be reminded, and the geological disaster analysis results are fed back to the local emergency management department in real time to start the disaster prevention, mitigation and rescue plan in time. The idea is novel and the method is innovative.
