In the UWB positioning system, the layout of the positioning base station determines the dimensions of UWB positioning (zero-dimensional, one-dimensional, two-dimensional, and three-dimensional). The positioning base station can be set in two situations: fixed and mobile.

 

There are two main ways to communicate between UWB positioning base stations and positioning tags: ToF and TDoA.

 

ToF (Time of Flight) is a time-of-flight ranging method. By measuring the time from departure to return of the pulse signal, multiplying by the propagation speed (the propagation speed of the pulse signal in the air is a fixed value v=300 000km/s), the round trip is obtained. The distance once divided by 2 is the distance between the UWB positioning tag and the positioning base station.

 

TDoA (Time Difference of Arrival) Time Difference of Arrival method, a method of calculation using time difference. Accurate absolute time is relatively difficult to measure. By comparing the time difference between signals reaching each UWB positioning base station and calculating the distance difference between the signal and each positioning base station, a hyperbola can be made with the positioning base station as the focus and the distance difference as the long axis. Three The intersection point of the set of hyperbolas is the position of the positioning label. ToF is a two-way ranging technology, while TDoA is a one-way ranging technology.

Yint electronics provides effective circuit protection for UWB positioning base stations: 

 

  • DC power supply: The power supply of UWB positioning base station is mainly 12~48V DC power supply, and some are equipped with POE power supply port. For 12V~48VDC power supply, Yinte Electronics recommends an industrial-grade two-level surge protection solution. The protection circuit is as follows:
