The invention provides a cluster risk avoiding method, a system, a computer readable storage medium and a server. The cluster risk avoiding method comprises the steps of obtaining geographical location information of a disaster area, the position information of all vehicles in the disaster area; depending on location information of a vehicle, clustering vehicles, dividing all vehicles into a plurality of area classes; circularly executing the operation of electing a leader from each region class; planning an optimal escape route for the leader by taking other vehicles in the area class as followers, and planning an escape route for all followers according to a preset escape rule by taking the optimal escape route of the leader as a reference until all vehicles reach a safe area. Accordingto the cluster risk avoiding method and system, the computer readable storage medium and the server, all users in one cluster can be guided to quickly and orderly leave a dangerous area when facing sudden situations such as natural disasters, so that the life and property safety of the users is guaranteed.

The invention provides a method and a system for preventing natural disasters in a small watershed based on emergency plan visualization and rapid mapping. The method comprises the following steps: acquiring various information of the small watershed; carrying out rapid drawing to form a 3D simulation map; optimizing the 3D simulation map, and speculating the occurrence category and the occurrence possibility of the natural disaster so as to propose a preliminary emergency plan; and adjusting and optimizing the initial emergency plan to form a final emergency plan. A 3D simulation map is constructed and optimized through various types of information of the small watershed, so that the possibility, the occurrence area, the occurrence category and the occurrence time of the natural disasters in the small watershed area can be automatically calculated, and the prevention efficiency of the natural disasters in the small watershed area is improved; besides, the 3D simulation map can visually display the deduction process, so that people can visually and clearly observe the layout of the area where natural disasters possibly occur, the harm caused by the disasters and the like, and reference and auxiliary effects are achieved on prevention of the natural disasters. The problem of how to prevent small watershed natural disasters is solved.

The present application relates to the technical field of VR and natural disaster handling, and in particular, to a VR natural disaster scene interaction system, method and cloud platform. The landslide warning VR terminal that has been upgraded exists in all landslide warning VR terminals corresponding to the landslide warning area. If there is a landslide early warning VR terminal that has not been upgraded, the landslide early warning monitoring information reported by the upgraded landslide early warning VR terminal is forwarded to the preset monitoring information cache device, which can avoid some landslides remaining in the landslide early warning monitoring information database. The landslide early warning and monitoring information before the upgrade of the early warning VR terminal and the landslide early warning monitoring information after the upgrade of some landslide early warning VR terminals will cause a large error in the record of the landslide early warning and monitoring information, thereby improving the accuracy of the record of the number of landslide disaster events in the landslide early warning area. Therefore, efficient landslide warning and monitoring can be carried out based on accurate records of the number of landslide disaster events.
