UWB ultra high precision positioning system architecture

UWB Ultra high precision positioning system architecture diagram

UWB Ultra high precision positioning system uses wireless pulse signal , Achieve 30 Positioning function within cm , Whole UWB The ultra-high precision positioning system consists of the equipment layer 、 The network layer 、 Algorithm layer and application layer .

UWB The equipment layer of ultra-high precision positioning system includes UWB Location base station 、UWB Synchronous base station 、UWB The positioning tag and the wireless gateway are composed .UWB The positioning base station can detect UWB The distance of the label , According to multiple base stations , Complete one-dimensional or two-dimensional positioning ;UWB The purpose of synchronizing base stations is to solve the problem of time synchronization between different base stations , We adopt a wireless synchronization scheme , And one UWB The synchronous base station can adapt to all the positioning base stations within the coverage ;UWB The positioning tag is carried by the positioning object ; The function of wireless gateway is in places where weak current construction cannot be carried out , Complete the network erection .

UWB The network layer of ultra-high precision positioning system is the traditional common switch 、 Router 、 Firewall, etc .

UWB The algorithm layer of ultra-high precision positioning system mainly includes TOF and TDOA as well as DOA Three positioning algorithms , The corresponding is the flight time of single base station , Arrival time difference of multiple BTSs, etc .

UWB The application layer of ultra-high precision positioning system is the user interface that we finally present in front of users , We provide a desktop 、 Webpage 、 mobile phone APP And a variety of access methods for wechat applets .
