Abstract

The invention discloses a mining emergency rescue communication method based on a Mesh network technology. The mining emergency rescue communication method is characterized by comprising the following steps: using Mesh routers as a base to constitute a communication network; networking the Mesh routers according to a Mesh protocol to dynamically and automatically establish network-like wireless links; transmitting data according to the distances of the Mesh routers; if the nearest Mesh router is jammed, according to the flow of each of the Mesh routers, selecting the Mesh router with the lowest flow to transmit a data packet; connecting the Mesh routers with mining intrinsic safety type cameras to acquire video image information and with mining mobile terminals to perform voice communication. The mining emergency rescue communication method disclosed by the invention is flexible and convenient for network construction, so as to greatly reduce the network infrastructure cost.

Description

technical field [0001] The invention relates to a mine emergency rescue communication method based on Mesh network technology. Background technique [0002] At present, the communication system of coal mines has evolved from traditional voice telephones (explosion-proof telephones) to network-based wired and wireless communication methods, and the content of communication has also evolved from traditional voice to data services such as video surveillance, environmental monitoring, and automatic control. For collaborative operations, and in the event of disasters or other emergencies, it is convenient for relevant personnel to communicate quickly, organize rapid rescue and evacuation, so as to improve production efficiency and reduce accidents. The existing cellular network cannot meet the needs of the coal mining industry because of its large deployment overhead. Therefore, most of the existing underground wireless communications in coal mines are communication systems base...
