Abstract

The invention discloses a wireless positioning method and system. The wireless positioning system comprises at least one synchronous base station, a plurality of positioning base stations and at leastone positioning label and further comprises network communication equipment and a computing server. the synchronous base stations can also be used as positioning base stations at the same time, and the synchronous base stations and the positioning base stations further comprise high-precision clocks. The method comprises the following steps: a synchronization base station sends a synchronizationsignal at an interval of a period of time; the positioning base station receives the synchronization signal and uploads the data to the computing server; the computing server performs time synchronization on every two positioning base stations; whe positioning tag broadcasts a positioning signal once every other period of time; the positioning base station receives the positioning signal and uploads the data to the computing server; and the computing server computes the coordinates of the positioning tag.

Description

technical field [0001] The invention relates to the field of sensor measurement, in particular to a wireless positioning method and system. Background technique [0002] With the development of emerging fields such as the Internet of Things and robots, high-precision indoor positioning technology has attracted more and more attention. The traditional indoor positioning accuracy based on WiFi, Bluetooth and other technologies is poor, and the positioning accuracy is usually only a few meters, which cannot meet the needs of high-precision positioning. Influenced by the environment and occluders, the practicability is poor. [0003] Ultra-wideband technology (UWB) has the advantages of low power consumption, strong anti-interference ability, and strong anti-multipath effect ability. It has been widely used in high-precision indoor / outdoor positioning in recent years. Among them, the UWB positioning scheme based on TOF (Time of Flight) is the most used, which is characterized ...
