Method and apparatus for preventing dispersion of team members

Abstract

The invention discloses a method and apparatus for preventing dispersion of team members. The method comprises the following steps: acquiring, by a monitoring terminal, wireless signals transmitted bybeacons of the team members; respectively calculating the distances between the beacons and a monitoring terminal according to the signal strength of a plurality of wireless signals; and judging whether the team members fall behind according to a plurality of calculated distances, and performing alarm when it is judged that the team members fall behind. By adoption of the technical scheme of theinvention, a method for preventing dispersion of team members based on the radio signal ranging technology is provided, the method is not affected by the positioning conditions of location informationor network facilities, real-time computing is performed, the computing error is small, and the algorithm difficulty is low.

Description

Technical field [0001] This application relates to the field of communication technology, and specifically to a method and device for preventing the separation of team members. Background technique [0002] In scenes such as traveling in groups (such as walking and cycling), the team is often disturbed by other people or the environment, which can easily lead to the separation of team members. Especially in the process of marching, the team leader needs to keep abreast of the situation of the team members in time to prevent members from getting lost or falling behind in an unfamiliar environment, which requires more energy to pay attention to the progress of the entire team. For a team with a large number of people, it is very difficult to count the number of people manually in real time because the travel process is fluid. Especially in the scene where the team travels with bicycles and other tools, the team leader is responsible for leading the way and taking care of it. The s...

Problems solved by technology

However, there are the following problems in relying on the acquisition of user location information: (1) there is a deviation in the calculation distance

However, due to the interference of geographical factors during the journey, it is sometimes impossible to obtain accurate geographic location information

For example, during rock climbing activities, the relative position of the team members is in a vertical relationship, and the GPS satellite positioning will be distorted; another example, in the deep mountains where the base station cannot cover, it is difficult to obtain location information through the base station, which will lead to distance calculation results Deviation on

(2) Complicated calculation method

(3) High equipment requirements

In addition, in the existing method, the location information of the first user needs to be sent to the center. Therefore, when the network signal is not good, there will be problems such as signal delay or failure to send to the center, resulting in deviations in the alarm time.

The existing team anti-dispersion method is limited by the collection method of location information and surrounding environmental conditions, which will lead to time deviations in calculation results and affect the real-time performance of alarms
