Abstract

The present application discloses UWB (Ultra-Wide Band) fine positioning method, device and equipment and a computer-readable storage medium. The method comprises the steps of balancing an optimal observation solution and an estimated solution through Kalman filtering by fully utilizing motion information to obtain a Kalman estimated solution; and compensating error caused by modeling and uncertain noise, of the Kalman filtering, through a BP (Back Propagation) neural network at the same time to obtain an optimal final estimated solution. The method has the advantages that the positioning result is more accurate and the technical problem that large error exists in a conventional UWB precise positioning method is solved.

Description

technical field [0001] The present application relates to the technical field of wireless positioning, and in particular to a UWB precise positioning method, device, equipment and computer-readable storage medium. Background technique [0002] Power field operation management is an important part of electric power production safety. The environment of electric power field operations is complex and dangerous. There may be risks such as electric field workers entering live areas by mistake, touching live equipment by mistake, and risky operations. Therefore, There needs to be strong supervision of workers working on electrical sites. Although the power grid company has used technical means such as physical fences, electric inspection tools, and proximity alarms to prevent, but due to insufficient implementation of on-site safety measures, it is still unable to solve the potential risks of on-site operations. It needs to be precisely positioned. The existing GPS positioning te...
