基于超声波测距的室内定位设计

Indoor positioning design based on ultrasonic ranging

针对目前行业内对高精度室内定位设计的迫切需求,文中设计了一种可以用于室内定位或者室外短距离移动物体定位的定位系统。超声波定位设计主要采用对射式测距的方法,这就需要有若干个接收器和一个发射器相配合,几个接收器在空间上相对静止。通过测量超声波收发两端的距离,再利用三边定位的方法计算出被测目标的位置,进而得到发射器和接收器之间相对位置的坐标。同时改进发射系统和接收系统,得到了一种盲区小,精确度高的室内定位设计。

A positioning system that can be used for indoor positioning or outdoor short-distance moving object positioning is designed in view of the urgent need for high-precision indoor positioning design in the industry,The ultrasonic positioning design mainly adopts the method of on-beam ranging,which requires several receivers and one transmitter to cooperate,and several receivers are relatively static in space. By measuring the distance between the two ends of the ultrasonic transmission and reception,the position of the measured object is calculated by the method of three-side positioning,and the coordinates of the relative position between the transmitter and the receiver are obtained. At the same time,the transmitting system and the receiving system are improved,and an indoor positioning design with small blind area and high precision is obtained.
