Abstract

The invention provides an indoor positioning method and system based on UWB, and the method comprises the steps: employing a TWR positioning method, a positioning server calculating the position of alabel according to the distance between a base station and the label, and achieving the positioning of the label. According to the technical scheme provided by the invention, the white list base station is arranged for the label, so that the label can be positioned within the shortest time, and meanwhile, the mutual conflict between UWB signals is effectively avoided. Moreover, according to the technical scheme of the invention, the white list base station is adjusted according to the distance between the base station with the white list and the label, the positioning network is optimized, andthe positioning precision is ensured. According to the technical scheme, no complex requirement is needed for arrangement of the base station, the construction difficulty is low, the positioning precision is high, and good application value and popularization value are achieved.

Description

Technical field [0001] The invention relates to the field of wireless communication and positioning systems, in particular to an indoor positioning method and system based on UWB. Background technique [0002] UWB is a carrier-free communication technology that uses non-sine wave narrow pulses from nanoseconds to picoseconds to transmit data. By transmitting extremely low-power signals over a wide frequency spectrum, UWB can achieve data transmission rates of hundreds of Mbit / s to several Gbit / s within a range of about 10 meters. Its anti-interference performance is strong, the transmission rate is high, the system capacity is large, and the transmission power is very small. Communication equipment can achieve communication with a transmission power of less than 1mW. Its electromagnetic radiation has little impact on the human body and has a wide range of applications. Especially in the field of indoor personnel positioning, this technology is widely used and is one of the mos...
