Problems solved by technology

Among them, the restoration of power supply is a key link, but it is very dependent on the delivery of power supplies for emergency repairs. However, natural disasters also caused great damage to communication lines, making it difficult for conventional communication methods to function, which further led to the instability of on-site information in disaster areas. Passed back to the rear, making it impossible to plan a fast and reliable transport path

Embodiment 1

[0058] Path navigation method in disaster area scene

[0059] Such as figure 1 As shown, the path navigation method in the disaster area scene includes the following steps:

[0060] Step 1: Based on the original electronic map and individual excavation trajectories, establish an emergency augmented electronic map.

[0061] The present invention adds individual soldier excavation tracks on the basis of existing electronic maps to generate emergency augmented electronic maps, wherein the sources of individual soldier excavation tracks include two situations, one is similar to internal roads and other sources that are not recorded in existing electronic maps The other is the situation where it is difficult to form a road itself, but it can ensure the passage of emergency transport vehicles after treatment, such as open spaces where walls can be opened, farmland where vehicles can pass, etc. The data in both cases can be reflected in the trajectory points collected and returned ...

Abstract

The present invention relates to a path navigation method and device in a disaster area scene. Based on the original electronic map and individual soldier excavation tracks, an emergency augmented electronic map is established; based on the emergency augmented electronic map, a roadblock avoidance strategy and a staggered repair strategy are established; The roadblock avoidance strategy and the time-staggered emergency repair strategy establish a repair path planning model and an offline shortest path model; based on the emergency repair path planning model, calculate and obtain an optimal emergency repair path; based on the offline shortest path model, calculate and obtain an optimal transportation route . The invention can obtain the optimal repair route and the optimal transport route, and ensure that the transport team can reach the demand point of emergency repair materials quickly and reliably.

Description

technical field [0001] The invention relates to a route navigation method and device in a scene of a disaster area. Background technique [0002] In order to reduce the losses caused by natural disasters as much as possible, the efficiency of post-disaster work must be guaranteed. Among them, the restoration of power supply is a key link, but it is very dependent on the delivery of power supplies for emergency repairs. However, natural disasters have also caused great damage to communication lines, making it difficult for conventional communication methods to function, and further leading to unstable on-site information in disaster areas. Back to the rear, so it is impossible to plan a fast and reliable transportation path. [0003] The existing individual soldier system can go deep into the disaster area for data mining and collection, obtain a large amount of on-site data, and transmit the data back to the rear through communication methods such as Beidou short messages. ...
