Abstract

The embodiment of the invention provides a network communication path selection method of a same-frequency relay emergency system, and aims to solve the problem that a good network communication path cannot be established rapidly and effectively in a short time in wireless networking. The method in the embodiment of the invention comprises the following steps: acquiring signal field intensity of each networking node of a same-frequency relay radio station; acquiring a data error rate of each networking node of the same-frequency relay radio station; and confirming a communication path of the networking according to the signal field intensity and the data error rate. The embodiment of the invention also provides a same-frequency relay emergency system, and a wireless emergency communication network which is flexible for networking and only needs a single-frequency link.

Description

technical field [0001] The invention relates to the field of emergency communication, in particular to a same-frequency relay emergency system and a network communication path selection method thereof. Background technique [0002] In today's society, the increasing number of large-scale gatherings and various emergencies such as earthquakes, fires, and terrorist incidents are constantly testing the government and its corresponding functional agencies. The emergency communication system assumes the role of "vanguard" in delivering first-hand information in a timely, accurate and smooth manner when urban operations encounter sudden disasters or accidents. It is the central nerve for decision makers to correctly direct emergency rescue and disaster relief. [0003] Emergency communication support has the characteristics of uncertain time, uncertain location, and uncertain scope. The system needs autonomous networking and rapid configuration functions. Each node can be flexibly...
