Abstract

The invention discloses a team exploration auxiliary communication and management method based on a wireless sensor network. A plurality of unpredictable losses of individuals, teams and even the whole society can be occurred caused by the fact that various extreme climates and bad natural environments are inevitable in team exploration. The method is a feasible scheme for exploring and solving communication and management in the team exploration. Based on the WSN (Wireless Sensor Network) technology, the method applies a ZigBee network to realize transmission of voice short messages in the team, and provides high-efficiency and energy-conservation positioning service through analyzing relative position information among general member nodes, enhanced member nodes and team leader nodes and assisting by GPS (Global Positioning System) positioning information which is provided by anchor nodes after the nodes and the information are synthetically processed. Under various extreme environments of existing systems incapable of working effectively, the method can reduce risk, avoids possible accidents, and improves the success rate of processing abnormal accidents.

Description

technical field

[0001] The present invention is based on the application scheme of wireless sensor network (Wireless Sensor Networks: WSN) technology in team exploration, which provides an important solution to solve the problem of difficult guarantee of instant communication in team exploration, and belongs to the technology of Internet of Things field. Background technique

[0002] Team expeditions often face challenges from various extreme environments, so it is of great significance to ensure smooth communication and reliable management during team expeditions. However, because traditional communication solutions cannot guarantee their reliability and availability in various extreme environments, they cannot reduce the risks brought about by harsh external environments. After investigation, it is found that the existing team expedition communication scheme mainly has the following problems:

[0003] (1) Excessive reliance on the Global Positioning System (GPS) for posi...
