[0059] Figure 1 An instant warning method after a road collapse or a bridge collapse is provided in an embodiment of the present invention and is applied to a vehicle-mounted terminal. The method includes:

[0060] S11, obtaining metadata features on the road to be warned, collecting road maintenance features of the road to be warned, and determining candidate risk areas for road identification based on the road maintenance features;

[0061] Specifically, the metadata feature belongs to the road to be warned, and the metadata feature can be a construction unit or management unit feature. The metadata feature is associated with the attribute tag of the road to be warned, so that the metadata feature can be obtained to obtain the maintenance feature of the road to be warned, but the data of other roads to be warned will not be obtained. The vehicle terminal can be an APP installed on the mobile terminal.

[0062] The maintenance characteristics of roads to be warned include road life deviation value, road material, construction and maintenance level, climate level, accurate risk area level, similarity of no-traffic history, similarity of maintenance external environment layout, etc. Indicators to be warned can be increased based on actual needs.

[0063] S12, obtaining the road identification candidate risk area to obtain the corresponding associated risk area set and the assessment warning risk area set, and delineating the accurate risk area according to the associated risk area set and the assessment warning risk area set;

[0064] After obtaining the metadata features on the road to be warned through the vehicle terminal, the associated risk area set and the assessment warning risk area set are obtained on the vehicle terminal. The associated risk area set can be obtained on the left side of the acquisition interface of the vehicle terminal, and the assessment warning risk area set can be obtained on the right side of the acquisition interface. In addition, the associated risk area set can also be obtained on the upper part of the acquisition interface, and the assessment warning risk area set can be obtained on the lower part of the acquisition interface.

[0065] The set of associated risk areas includes: road life associated risk areas, road material associated risk areas, construction and maintenance associated risk areas, climate associated risk areas, maintenance external environment associated risk areas, and serious disaster associated risk areas.

[0066] The associated risk area set and the assessment warning risk area set can be set based on actual needs. By obtaining the associated risk area set and the assessment warning risk area set, users can conveniently learn the indicators to be associated that can be warned.

[0067] S13, collecting vehicle navigation information of a set of traveling vehicles, and laying out circuits and warning facilities in the accurate risk area according to the vehicle navigation information;

[0068] The vehicle navigation information is a specific lane navigation request of the vehicle, which includes a specific road area to be passed through, and performs detection and early warning of relevant risks on the road area;

[0069] Specifically, the acquisition interface of the vehicle terminal is a touch screen. You can directly click on the associated risk area operation to configure the associated risk area. You can select one associated risk area and one assessment and warning risk area to associate; you can also select several associated risk areas. When two or more associated risk areas are selected, only one assessment and warning risk area can be selected. When two or two associated risk areas are selected in the assessment and warning risk area, only one associated risk area can be selected.

[0070] The identification and division of potential disaster risk areas on roads can be determined based on the existing technical theories and practical experience of the road and bridge industry, mainly including the following sections of roads where disaster risk areas may occur:

[0071] (1) Filled road sections that may experience landslides or collapses due to roadbed filling, especially high fill sections and fill sections with steep cross slopes of the original terrain.

[0072] (2) Unfavorable geological sections where roadbed slippage, collapse, and subsidence may occur due to adverse geological reasons, including sections with weak sliding surfaces, weak interlayers, and groundwater seepage.

[0073] (3) Road sections where natural disasters around roads and bridges may cause roadbed sliding and collapse, which may lead to bridge collapse, including sections that are seriously threatened by floods, mud-rock flows, rockfalls, landslides, etc.

[0074] (4) Road sections where the bridge beam may break or collapse due to natural disasters at high altitudes on the side of the bridge, including sections with high risk of falling rocks, landslides, etc. at high altitudes on the side of the bridge.

[0075] (5) Road sections where roadbed sliding and collapse may occur due to other reasons around roads and bridges, which may lead to bridge collapse, including sections near areas where disasters such as explosions, collisions, and other serious disasters may occur.

[0076] For example, if the configured associated risk area is a road life associated risk area, the associated degree is the road life deviation value; or if the selected associated risk area is a road life associated risk area and a road material associated risk area, the associated degree is the road life deviation value and the road material.

[0077] The classification of road potential disaster risk areas is based on the general method of current industry risk area classification, and the risk areas are divided into Level I (low risk area), Level II (medium risk area), Level III (high risk area), and Level IV (extremely high risk area). Level I, II, III, and IV risk areas are marked in green, yellow, orange, and red, respectively.

[0078] Level I, low risk area: The risk level is acceptable, current response measures are effective, and there is no need to take additional technical or management preventive measures.

[0079] Level II, moderate risk area: The risk level is conditionally acceptable, and the project needs to further implement preventive measures to improve safety. Take certain measures according to the actual situation of the project, such as strengthening the treatment of unfavorable geology, using good filling materials, improving the safety of the structure, and reducing the possibility of roadside risk areas.

[0080] Level III, high risk area: The risk level is conditionally acceptable, and measures to reduce safety risk areas must be implemented, and emergency plans need to be prepared. Measures must be taken, including strengthening the treatment of poor geology, using good filling materials, improving the safety of structures, and reducing the possibility of roadside risk areas.

[0081] Level IV, extremely high risk area: The risk level is unacceptable and effective response measures must be taken to reduce the risk level to Level III or below.

[0082] On road sections where accurate risk areas may occur, the potential risk areas are divided into the following sections based on the scope of impact of the potential risk areas and taking into account the needs of driving safety.

[0083] Potential disaster area: The area where serious disasters such as roadbed collapse, roadbed sliding, roadbed subsidence, and bridge collapse may occur, which is determined based on the accurate identification results of the risk area.

[0084] Safety buffer zone: The distance outside the potential disaster area, including safety distance, vehicle turning around, emergency rescue, etc.

[0085] Deceleration and braking zone: The distance outside the safety buffer zone, determined by the stopping sight distance corresponding to the driving speed on different road sections. It is the distance required for normally traveling vehicles to brake and decelerate to stop after receiving the warning information. The stopping sight distance is specified in accordance with the parameters of the current industry technical specifications.

[0086] Normal driving area: the normal driving area outside the deceleration and braking area.

[0093] S32, associating one or more accurate risk areas associated with the one or more accurate risk area types from an associated history database, wherein the associated history database is set in the vehicle-mounted terminal;

[0094] S33. Based on the first association indicator, obtain one or more third accurate risk areas associated with the first association indicator in the one or more accurate risk areas as accurate risk areas associated with the configured assessment warning risk area, wherein each of the one or more accurate risk areas includes a third accurate risk area.

[0095] In one embodiment, various accurate risk areas may also be set in the cloud platform. Therefore, when various accurate risk areas are set in the cloud platform, and when one or more associated risk areas and one assessment warning risk area are configured in step S12, such as Figure 4 As shown, step S12 includes the following steps:
