Personnel Positioning and Management System Based UWB in Shipyard

There are many people and various functional areas in large shipyard, and the space of shipyard is relatively closed, so it is necessary to know the positioning information of the people in the shipyard to carry out more fine management. Indoor positioning technology based on UWB has the advantages of high positioning accuracy and strong anti-interference ability. A personnel positioning management system based on UWB in shipyard has been studied and designed in the paper. An improved positioning algorithm based on trilateral location algorithm and a hybrid network architecture of WIFI and TCP/IP have been proposed. The indoor positioning system porotype has been built in Rockwell laboratory of our school, and the performance verification test has been carried out. The experimental results show that the error of fixed-point is about 14cm and the error of trajectory experiment is about 20cm.
