一种智能设备室内定位系统和方法
摘要：
本发明公开了一种智能设备室内定位的系统和方法，属于室内定位技术领域，包括信标和应用软件。信标间隔向外广播信号，广播内容包括信号强度和身份标识UUID。智能设备软件由信号采集、测距、室内地图部分组成。信号采集部分利用智能设备自带的加速度计、陀螺仪、地磁传感器、蓝牙、WIFI等采集手机周围信标的信号强度，加速度，方向等信息。测距是指利用信号强度与加速度梯度融合的测距算法，计算信标到智能设备的距离；地图部分包括室内地图和信标地理位置，当获得运动方向、速度和距离信标的距离时，通过查询地图，获得相应的地理信息，实现智能设备的室内定位。
摘要（英）：

The invention discloses a smart device indoor positioning system and a smart device indoor positioning method, and belongs to the technical field of indoor positioning. The system comprises a beacon and application software. The beacon broadcasts a signal to the outside at intervals, and the broadcast content includes signal strength and identity UUID. The smart device software is composed of a signal acquisition part, a ranging part and an indoor map part. The signal acquisition part acquires the signal strength, acceleration, direction and other information of a beacon around a mobile phone through an accelerometer, a gyroscope, a geomagnetic sensor, Bluetooth and WIFI of the smart device. Ranging refers to the calculation of the distance from the beacon to the smart device based on a signal intensity and acceleration gradient fused ranging algorithm. The map part includes an indoor map and the geographical location of the beacon. When the moving direction and speed and the distance from the device to the beacon are obtained, corresponding geographic location information is obtained by querying the map, and thus, indoor positioning of the smart device is completed.
