UWB Wireless Ranging

 

UWB wireless pulse ranging base stations can be used for long-distance mutual ranging, for crane positioning, bucket wheel positioning and ranging, and track equipment ranging and positioning to achieve collision avoidance and automatic control.


Ranging principle: As shown in the figure below, a ranging request pulse will be initiated from the base station to the master station at T1 time, and the ranging request pulse will reach the master base station at T2 to complete a ranging, and the flight time of the pulse between the master and slave base stations is T2 minus From the result of removing T1, it is known that the pulse movement speed is approximately the speed of light C, so that the distance between the master and slave base stations is D=C*(T2-T1).

 



Source of ranging error: The first ranging principle shows that the distance between master and slave base stations is D=C*(T2-T1), C is a fixed value, and the cause of D error is mainly caused by flight time error. The presence of obstacles between the base stations will cause the time difference to increase and cause ranging errors. The occlusion mentioned here should mainly avoid the occlusion of metals, solid walls and human bodies. These occlusions will cause the ranging error to become larger. Because the ranging pulse uses ultra-wideband pulses, its diffraction ability is poor. If there are close antennas The occlusion of the distance will inevitably lead to a larger distance error.

Ranging mode: The one-to-many ranging mode can realize the ranging from one base station to multiple base stations. The distance between the main base station and each slave base station will be output from the main base station. The many-to-many ranging mode will be able to realize the ranging of multiple master stations and multiple slave base stations, and output the distance from the master base station to the slave base station.

Precautions for equipment installation


• The installation height of the equipment is not less than 1 meter;


•Equipment installation can be fixed with screws or hoop;


• Ensure that the master and slave base stations, especially the antennas, need to see each other;


• There should be no obstruction between the base stations, especially between the antennas.
