基于北斗及蓝牙的室内外无缝连续定位系统设计

Design of Indoor and Outdoor Seamless and Continuous Positioning System Based on Beidou and Bluetooth

在航空物流领域,主要采用航空容器集装设备及无动力装置车辆(拖斗车)进行货物航空运输及地面流行性运输,其在货站内及机场之间进行转运。在室外,可以采用卫星定位的方式对其位置进行监控,但在货站内无法获取其卫星定位位置,因此设计了一种基于北斗及蓝牙到达角(AOA)技术的高精度定位方式,实现了室内外无缝连续定位系统。该系统的建设通过科技创新的技术手段提高航空货运物流领域面临的货物流动性无法确认的相关难题,以室内外位置定位为引领,以服务于业务场景为系统根本,极大地提高了航空货物运输领域的生产效率。

In the field of aviation logistics,air container equipment and unpowered vehicles(trailers)are mainly used for air transportation of goods and popular ground transportation.When the transfer is conducted between the cargo station and the airport,the location can be monitored by satellite positioning when outdoors,but the satellite positioning cannot be obtained in the cargo station.Therefore,a high-precision positioning method based on Beidou and Bluetooth AOA technology is designed,realizing an indoor and outdoor seamless and continuous positioning system.Through the technological innovation,the problem of the unconfirmed cargo mobility is solved in the air cargo logistics field by the system,with the indoor and outdoor positioning as the guidance and providing service for the business scenario system as the basis.Finally,the production efficiency in the air cargo transportation field has been greatly improved.
