Emergency communication system and method

Abstract

The invention discloses an emergency communication system. The system consists of an on-scene communication unit, a relay system unit and a terminal station, wherein the on-scene communication unit is bi-directionally communicated with the relay system unit and the terminal station; the relay system unit comprises a backbone relay station which is prearranged at a high-altitude position; and a corresponding supplementary relay station is prearranged between the backbone relay station and an on-scene emitting station in the on-scene communication unit. Correspondingly, the invention also provides an emergency communication method. In the method, communication connection between the terminal station and the on-scene communication unit can be established at the first time so as to transmit an instruction and feed back information in real time. The system and the method have the advantages of rapid response capacity, strong maneuverability, high reliability and high cost performance.

Description

technical field [0001] The invention relates to the field of communication, in particular to an emergency communication system and method. Background technique [0002] When a sudden natural disaster strikes in an instant, the power, communication, transportation, energy and other infrastructure at the disaster site may be damaged. At this time, the most important thing is to establish contact between the disaster area and the outside world, and report the real situation of the disaster site in the first time period, so as to facilitate the disaster relief work. However, it may be impossible to obtain any communication with the outside world due to the paralysis of the public communication network, the inability to activate the original emergency communication tools, and the accident of relevant personnel. At the same time, it is very likely that vehicles will be difficult to pass due to damage to roads and bridges. Under such circumstances, it may be one of the most effect...

AI Technical Summary

Problems solved by technology

The airdrop method may be delayed due to airdrop review procedures, weather, night and other reasons; the application of roads (or waterways) and vehicles (or boats) may be restricted; the time delay of the walking method is obvious

[0007] Therefore, due to the uncertainty of the area of ​​sudden natural disasters, this kind of external force that calls the area under the jurisdiction of the disaster area has an uncertain time and space distance, and there are certain difficulties in operating procedures and time. Delays in management and delays in decision-making
