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...

Problems solved by technology

[0005] The disadvantages of the existing technology are: the existing multimedia communication equipment for mines has a single function, and the wireless transmission power consumption, transmission bandwidth and transmission distance indicators are all restricted by each other, and cannot well support the real-time and reliable transmission of multimedia communication services

Although the existing terrestrial WiFi wireless Mesh network has the advantages of supporting IP interconnection technology, high bandwidth, multi-hop transmission, network self-organization, dynamic routing and self-learning, etc., it is limited by the power supply mode and power capacity used in mines

Although we have proposed a multi-functional wireless Mesh routing device for multi-RF mining, there is still a lack of a gateway device that can match the multi-functional wireless Mesh routing device for multi-RF mining in the prior art, and it is required to support multiple communication networks The integration of multimedia communication services can meet the real-time and reliable transmission of multimedia communication services, and can adapt to the limitations of mine underground power supply methods and power capacity
