Effective position tracking system in exhibition environment

Abstract

The present invention provides an efficient location tracking system in an exhibition environment that enables indoor positioning of a target node through cooperative positioning of anchor nodes and virtual anchor nodes. The system comprises: one or more anchor nodes configured to transmit Bluetooth signals; one or more virtual anchor nodes, wherein the virtual anchor nodes are configured to send a Bluetooth signal to a target node; and a target node which is configured to receive Bluetooth signals from the anchor node and the virtual anchor node, and determine the indoor position of the target node according to the received Bluetooth signals from the anchor node and the Bluetooth signals from the virtual anchor node. 本发明提供一种展览环境中的有效位置跟踪系统，其通过锚节点和虚拟锚节点的合作定位来实现对目标节点的室内定位，该系统包括：一个或多个锚节点，所述锚节点被构造为发送蓝牙信号；一个或多个虚拟锚节点，所述虚拟锚节点被构造为向目标节点发送蓝牙信号；以及目标节点，所述目标节点被构造为从所述锚节点和从所述虚拟锚节点接收蓝牙信号，并根据所接收到的来自锚节点的蓝牙信号和来自所述虚拟锚节点的蓝牙信号，来确定所述目标节点在室内的位置。
