domestic hazardous chemicals tend to be stacked in the warehouse without effective methods of monitoring stacking distance
distance from the wall
zenith distance and column spacing. Compared with other positioning technology
UWB technology can get a relatively accurate position of goods
but not accurate enough to meet the existing regulatory requirements. Combining with storage characteristics of hazardous chemicals
the research analyses positioning principles and the main factors that affects positioning accuracy of UWB (ultra-wide band) technology and suggests to monitor positioning of hazardous chemicals in the warehouse by UWB technology. The Thiessen polygon vectors compensation method is proposed to improve the positioning accuracy of hazardous chemicals in the warehouse. It is proved by experiments that this method can effectively improve the positioning accuracy and is suitable for the positioning and monitoring of hazardous chemicals.
