The invention discloses a Bluetooth indoor navigation system, comprising: a preset number of Bluetooth devices which are dispersedly arranged in a target space and broadcast data packets of coordinate information; and a mobile terminal with Bluetooth, wherein the mobile terminal is internally provided with a target space map and target position information, is used for receiving a plurality of data packets at any position in a target space, obtaining coordinate information of the Bluetooth devices, calculating the current position of the mobile terminal and obtaining an optimal navigation route. The target space map and the target position information are preset in the mobile terminal, so that the situation that accurate and effective information cannot be obtained due to weak network signals after a user enters the target space is avoided; the Bluetooth device actively broadcasts the coordinate information and the occupation state information of each parking space, the mobile terminals in the range calculate the navigation route, connection with a server is not needed, and the problems that the underground parking lot is poor in communication quality, network connection is interrupted, navigation information feedback is not timely, and real-time position updating lags behind are solved.
本发明公开了一种蓝牙设备室内导航系统,包括:预设数量的蓝牙设备,蓝牙设备分散设置于目标空间,并广播坐标信息的数据包;带蓝牙的移动终端,移动终端内预设有目标空间地图及目标位置信息,移动终端用于在目标空间内任一位置接收多个数据包,获取蓝牙设备的坐标信息,计算移动终端的当前位置并获取最优导航路线。通过在移动终端内预设目标空间地图以及目标位置信息,避免使用者进入目标空间后网络信号弱无法获取准确有效的信息;本蓝牙设备主动广播其坐标信息和各个车位占用状态信息,由范围内的移动终端计算导航路线,无需与服务器进行连接,解决了地下停车场通信质量差网络连接中断导致的导航信息反馈不及时,实时位置更新滞后等问题。
