1. Product use
The KT609 mine wireless communication system is a supplement to the coal mine's wired communication system, realizing mobile monitoring and inspection, emergency dispatch and other applications.
Provide a data transmission channel for the inconvenient installation of fixed mobile wireless terminal equipment underground. In the case where there is an explosive mixture of methane and coal dust but no corrosive gas that destroys the insulation layer, the computer system software can realize the monitoring of key locations in the coal mine. Video surveillance and voice communication support for underground personnel in coal mines.
