Problems solved by technology

At this stage, most UWB-based positioning systems use time-of-arrival (TOA) and time-difference-of-arrival (TDOA) positioning methods. In order to obtain high-precision position information, the system needs at least 3 or 4 base stations, and depends on the topology of these base stations. At the same time, the positioning system adopts wired data transmission, which leads to the increase of system equipment cost and layout cost, and there is a problem of low system flexibility

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a device and a positioning system integrating UWB single base station positioning and wireless data transmission. Background technique [0002] With the advent of the Internet of Everything era, people's demand for location information is increasing day by day, from outdoor positioning based on the Global Positioning System (GPS) to indoor positioning based on various wireless technologies, high-precision location information has brought people more and more More and more convenience. GPS adopts RTK method in an open outdoor environment to meet the needs of high-precision positioning, but satellite signals are easily affected by obstacles such as buildings and trees, resulting in a decrease in positioning accuracy or even failure to locate. Therefore, various wireless positioning technologies have been born, such as wireless local area network (Wireless Fidelity, WIFI), Bluet...
