基于UWB的船厂物流室内定位系统设计

为解决传统基于全球导航卫星系统(Global Navigation Satellite System,GNSS)的船厂物流定位解决方案无法在室内应用的问题,设计一种基于超宽带(Ultra Wide Band,UWB)的船厂物流室内定位系统。通过添加运动传感器芯片,动态调整UWB标签的工作时间,延长其续航。采用到达时间差(Time Difference of Arrival,TDOA)定位算法,减少标签与基站间单次定位需要的通信次数,降低坐标解算的复杂度,提升系统的易用性和可扩展性。该系统配合企业制造执行系统(Manufacturing Execution System,MES),可为船厂物流运输管理、托盘集配管控等生产环节提供新思路。

Design of Shipyard Logistics Indoor Positioning System Based on UWB

In order to solve the problem that the traditional shipyard logistics positioning solution based on Global Navigation Satellite System (GNSS) can not be applied indoors, a shipyard logistics indoor positioning system based on Ultra Wide Band (UWB) is designed. By adding the motion sensor chips, the working time of UWB tag can be adjusted dynamically to extend its endurance. The Time Difference of Arrival (TDOA) positioning algorithm is adopted to reduce the communication times required for a single positioning between the tag and base station, decrease the complexity of coordinate calculation, and improve the usability and scalability of the system. In the cooperation of the enterprise Manufacturing Execution System (MES), the system can provide a new train of thought for the shipyard logistics transportation management, pallet distribution control and other production links.
