Internet era, the indoor positioning has become a technology link of the construction of the Internet of things, to really play to the value of the location data, you need to collect location data has enough precision, cloud and cool science and technology research and development of UWB personnel positioning system has been widely applied in the field of Internet of things industry personnel positioning and asset management, in this small make up to take you to understand the factors influencing the UWB positioning precision of the obstructions,
Mask mainly refers to the obstacle between UWB positioning base station and UWB positioning labels, hindered the signal is received each other directly, thereby affect the UWB positioning,
1 solid wall
Solid wall block is deployed at the scene of the location area when UWB positioning system is one of the more common type of obstructions, a solid wall of the cover will make UWB signal attenuation 60-70%, positioning accuracy error up 30 centimeters, two or more than two wall entity wall block, will make UWB positioning can not be achieved,
So in the process of deployment of UWB base station, should avoid the solid wall block; Especially in the corner of the place, the deployment of the UWB base station was a little tight,
2 steel
Steel plate cover the uptake of UWB positioning pulse signal is severe, will make UWB positioning cannot be achieved completely, so be sure to keep in mind the deployment of UWB positioning base station should steer clear of steel block,
3 pole or trees
Poles or trees shade need to see the distance between them when UWB base station or the distance of the label, and UWB base stations and the relative distance of the tags are very small, for example, UWB base station and locate the label distance of 50 meters, right in the middle of the two poles or trees, 25 meters, what this shade, there is no influence, such as close to the base station or the label distance is less than 1 meter, influence is very big,
Above these three effects on UWB positioning accuracy is larger, the deployment of base station and the label for UWB should be considered in the process, the following two mask for the UWB positioning is small, the influence of most of the time under the influence of negligible,
Glass
Glass block for UWB positioning precision is not too big effect,
Board or clapboard
Average thickness of about 10 cm of wood or cardboard for UWB positioning precision is not too big effect,
Above that influence factors of UWB positioning accuracy and attenuation properties of UWB signals, cloud cool technology mainly for electric power, chemical industry involves the research and development personnel positioning system, in the field of positioning accuracy under the same construction investment performance is good, with the deep understanding of industry, let cloud cool technology personnel positioning system can play the most ideal result,
