Field personnel safety guarantee method and system based on dynamic position sharing

Abstract

The invention relates to a field personnel safety guarantee method and system based on dynamic position sharing. The method comprises the following steps: acquiring position basic information of a team and the current position of each field person; determining the position of the shortest distance from the current position of the field personnel to an action route; drawing a circle around the position of the shortest distance with an allowable deviation range as a radius, and determining an initial geo-fence of the field personnel; determining a pointing vector according to the position basic information of the team and the current position of the field personnel; expanding the initial geo-fence by using the pointing vector; acquiring the position of the field personnel in real time, and monitoring the field personnel by using the expanded geo-fence; and returning to the step of acquiring the position basic information of the team and the current position of each field person. The safety of field personnel is improved.

Description

technical field [0001] The invention relates to the field of dynamic location information sharing, in particular to a method and system for ensuring safety of field personnel based on dynamic location sharing. Background technique [0002] In recent years, outdoor sports are gaining more and more people's favor. Because the environment of outdoor sports is very complex and there are many uncertain factors, the risk of people being left behind or even missing during outdoor sports is extremely high. Once such a dangerous situation occurs, not only will it be difficult for the left-behind members to understand their own status and take the initiative to get out of trouble, but other members of the team will not be able to detect that some members are behind and start rescue in time, which will easily cause greater losses. With the continuous development of the outdoor sports industry, it is very important to develop a personnel safety guarantee method that can be applied in t...

[0004] At present, most geo-fences are set with fixed boundaries, or use a fixed landmark as the center point to plan a circular area to set the range. This type of fence has fixed boundaries; the concept of dynamic geo-fences has also been proposed in the technical field, but It is often centered on the field personnel themselves, and is dynamically updated with the movement of the field personnel. This kind of fence cannot limit the range of activities of the field personnel. It is only equivalent to transferring the landmark detection performed by the fixed fence from the server to the field personnel

Neither fixed geo-fences nor dynamic geo-fences currently use team information as the basis for generation, and the purpose is to limit the range of activities of field personnel and its application
