An Indoor Location System Based on Matlab and Capacitance Induction

提出了一种基于Matlab和电容感应的室内三维定位系统的设计方法。该系统主要由三维电容极板、电容采集模块、信号频率采集模块、实时串口通信模块、Matlab显示模块等组成。系统依据电容感应原理,通过测量监测区域三维电容基板之间电容值的变化量,换算出被测物体相对极板的距离,并通过Matlab图像显示窗口显示被测物体对应的三维位置。该室内定位系统特别适用于对进入监测区域的活动物体进行实时定位监测。

A design method of a three-dimensional indoor location system based on Matlab and capacitance induction is proposed. The system is mainly composed by the following modules, namely three-dimensional capacitance plates, capacitive acquisition module, frequency of the signal acquisition module, real-time serial communication module, Matlab display module. Based on the capacitance induction theory, the system can monitor the capacitance change between the three-dimensional plates and convert the distances from plates. Then the corresponding three-dimensional position of the object is displayed in the Matlab image display window. The indoor location system is suitable for real-time location monitoring for the active object in monitoring area.
