In the positioning architecture, the most typical is two kinds of architecture, one is the server architecture, that is, all the calculation is
completed in the background server, terminal architecture, location calculation is completed in the terminal. Hybrid mode is to locate
the base sample in the terminal, but through the data transmission channel, back to the server for calculation. These are described
below.
Server architecture
In this architecture, after the target is located and the base station interacts, the base station sends the sampled data back to the
server for position calculation. The architecture has the following features:
1, the calculation is carried out on the server;
2, the terminal does not need to know its own location, or even if necessary, there is no strict requirement in timeliness;
3, the terminal power consumption requirements are very strict;
System architecture
Typical technology applications:
UWB ToF is located
UWB upstream TDoA positioning
BLE AoA positioning
BLE Signal strength positioning based on gateway
ZigBee gateway based signal strength location
Terminal architecture
In the terminal architecture, the positioning terminal and the base station/anchor carry out data interaction (or only receive, no interaction)
and calculate their own position according to the obtained information.
This architecture has the following features:
1, do not limit the capacity of the terminal;
2. The base station/anchor basically has no interaction with the label, and the base station/anchor only sends;
3, the label is its own position;
4, due to the receiving time is relatively long, the terminal power consumption is not low;
5, the base station/anchor side may be battery-powered, simplifying the construction and reducing the difficulty of deployment.
System architecture:
Typical application architecture:
Satellite Positioning System (GPS/ Beidou/Galileo/Glonass)
BLE Beacon
BLE AoD
The most typical terminal here is a mobile phone.
Mixed mode
The hybrid model is generally mixed in the second mode. After the terminal collects the data, it does not calculate the position itself,
but calculates the position through the background server.
System architecture:
For our local scenario application, it can be
GPS location
BLE Beacon
GPS and Beacon integration positioning, etc
It can be widely used in chemical plants, construction sites and other scenarios.
