Description

technical field [0001] The invention relates to the field of multimedia wireless communication in mines, in particular to a multi-RF mine-used multifunctional wireless Mesh gateway device and a control system thereof. Background technique [0002] Mine safety production accidents and natural disasters occur frequently in our country. In order to facilitate the mine’s daily investigation of potential safety hazards and prevent them before they happen, and to avoid natural disasters in mines and serious and serious safety production accidents and disasters, emergency rescue forces can be quickly organized and done. It is of great and urgent practical significance to develop mine multimedia wireless communication equipment in order to make command decisions such as search and rescue. [0003] Traditional mine multimedia emergency communication is mainly wired. However, with the development of short-distance communication technologies such as underground wireless sensor networks...
