Abstract: A low-power multi-mode positioning information mining lamp is designed. By the fusion of multi-mode radio frequency technology and radio frequency scheduling method, the mine can realize the seamless transition and upgrading from regional positioning to ultra wideband accurate positioning; PA power amplifier and LNA low noise amplifier are used to optimize the transmission distance and ranging accuracy of UWB radio frequency technology, so as to solve the base station capacity and economic cost of underground location service system; at the same time, the upgradable design can realize the differentiated customized use needs, and can better provide underground location information services for coal mines.
