Precise space-time travel flow regulation system
— be based on UWB Ultra high precision positioning system
The accurate space-time travel flow regulation system of Benliu positioning is based on UWB Ultra high precision positioning system ,UWB Ultra wideband pulse , Can achieve 30 Precise positioning of CM . Only one synchronous base station and three positioning base stations are needed TDOA Algorithm can realize ultra-high precision positioning system . Facing different scenes , Ben Liu positioned UWB Ultra high precision positioning system is compatible TOF And so on , It can realize zero dimensional existence monitoring and one-dimensional linear positioning . With precise location , We can provide accurate flow adjustment , Provide effective tools and weapons for scientific protest .
- 1.2 System architecture
Ben Liu's precise positioning, space-time travel flow regulation system is composed of UWB The equipment layer of ultra-high precision positioning equipment 、4/5G Or the network layer composed of local LAN 、TDOA and TOF And the algorithm layer composed of a variety of filtering algorithms, including real-time positioning 、 Track playback 、 The application layer of close connection statistics .
- Equipment layer
The positioning accuracy of the equipment layer reaches 30 Centimeter UWB Location base station 、 The time accuracy reaches 1 Microsecond synchronous base station and standby for half a month UWB The positioning label consists of .
- The network layer
The network layer includes switches that summarize all positioning data to the server 、4/5G Transmission module 、 Wireless gateway, etc .
- Algorithm layer
The algorithm layer mainly includes the core TDOA and TOF Location algorithm 、 Independently developed by Benliu Z Curve trilateration Algorithm 、 Deep neural smoothing filtering algorithm .
- application layer
The application layer includes the Benliu map engine that can independently plan scenes 、 Positioning system data display module 、 Precise time and space travel flow adjustment business logic and open business data interface .
- 1.3 System Overview
Ben Liu positioning accurate space-time travel flow adjustment system mainly has real-time positioning 、 The track of history 、 Flow control 、 Close query 、 Epidemic hot spots 、 Follow up after the epidemic 、 Seven functions of automatic visualization .
- Real-time location
Real time query of all personnel in the current field and their specific locations
- The track of history
Playback the historical track of a person in different time periods
- Flow control
Preset the maximum number of people in a building or area , And control
- Close query
If positive , The system automatically determines the close connection and secondary close connection
