UWB personnel precise positioning and wiring-free centimeter-level high-precision positioning system

UWB personnel precise positioning, wiring-free centimeter-level high-precision positioning system

UWB-based solutions for safe positioning of power grid personnel, personnel positioning in nursing homes, underground personnel positioning, tunnel personnel positioning, children's amusement park personnel positioning, Hospital personnel positioning, and scenic area personnel positioning realize real-time positioning of personnel; stay alarms for electronic fences, and cross-border Alarm; work attendance; inspection and inspection; material inventory; and other functions. The system topology diagram is as follows:

Zero-dimensional positioning: A positioning base station implements presence induction detection of tags, which can be used in closed rooms and potholes. Xi'an Samsung Pool, Chengdu Maintenance Section, etc.

One-dimensional positioning: Two positioning base stations realize distance positioning of tags, which can be applied to tunnels, comprehensive pipe corridors, corridors, and park roads. Xiamen Pipe Gallery, Hengqin Pipe Gallery, Xining Pipe Gallery, Zhengzhou Metro, etc.

Two-dimensional positioning: Four positioning base stations perform coordinate positioning of tags, which can be applied to chemical plants, high-speed rail stations, substations, etc.

Positioning system composition

base station

To use UWB technology for indoor positioning in a space, a positioning base station needs to be installed in the space in advance. Installation and configuration Xiaowang Technology positioning base station communicates with the positioning tag through UWB signals to realize the positioning function of the tag.

  Label

Positioning tags are divided into personnel positioning tags and Asset positioning tags. People or assets to be located wear or install Xiaowang positioning tags. The tag emits UWB signals, communicates with the base station, and confirms the coordinate axis data so that the tag itself can be positioned.

Gateway

Collect the coordinate information sent by the positioning tag and send the data to the positioning engine through Ethernet.

Positioning engine

The positioning tag sends raw data to the Xiaowang data gateway in real time, and the data gateway sends the collected data to the positioning engine (located on the local server or sent to the cloud via MQTT). The positioning engine runs the positioning algorithm and calculates the coordinate position with the positioning tag in real time.

Display terminal

Display terminal: The tag coordinates calculated by the positioning engine are presented on the display terminal through the B/S architecture. Users can remotely log in and manage through any device with a browser such as PC, tablet, mobile phone, etc.

Solution advantages

Positioning software

Provides basic functions such as real-time display and various extended functions. Users can choose to match the extended functions according to actual needs.

Industry application

Each indoor positioning technology has broad prospects in the personnel positioning industry, and also has its own usage scenarios and user groups. UWB positioning technology has higher accuracy than RFID positioning technology, and is more suitable for industries that require higher positioning accuracy, such as chemical industry personnel positioning, coal mine personnel positioning, power energy personnel positioning, manufacturing personnel positioning, and public security and judicial personnel. Positioning, tunnel personnel positioning, etc.
