一种局部地面定位系统的研究与探索

Research and Exploration of Local Ground Positioning System

针对传统定位技术定位精度低、稳定性较差,无法在室内环境定位以及定位对象局限于数字设备的缺点,提出一种依靠物体对地面产生压力进行定位的方法。该方法通过在地面下铺设经过改进的矩阵扫描电路,实时获得地面所有物体踩压位置数据,将该数据通过互联网发送至用户智能终端实现定位。首先介绍了定位系统的原理,接着介绍局部地面定位系统中的一些参数,然后对智能终端程序进行流程分析并进行数据仿真,模拟了人在地面向各个方向行走时地面数据的变化并总结了其规律;最后,制作了相关硬件并根据仿真得出的算法进行了手机端软件的编写,完成了整个系统的开发,实现了局部地面定位系统在定位导航、安防监控、信息输入方面的功能。

Aiming at the low accuracy and low stability of the traditional positioning technology,the disadvantages of unable to locate in indoor environment and positioning objects are limited to digital devices,a local ground positioning system（ LGPS） was put forward which based on the theory that the position of ground object is related to where it produces pressure on ground. With the matrix scanning circuit under the ground tile,scanning data can be easily got in real-time in a section and send them back to the user＇ s intelligent terminal via Internet. First,the theory of positioning system was introducd and then described some parameter support LGPS,and then the process of the intelligent terminal program was analyzed and simulated the data change when people walk in every direction on the ground and find out the algorithm pattern. Finally,all the hardware and software were developed in the LGPS and realized its function in positioning,navigation,security and message input.
