基于无线传感网络的井下定位系统设计与实现

Design and implementation of UNDERGROUND POSITIONING SYSTEM BASED ON WIRELESS SENSOR NETWORK

针对传统定位系统井下定位精度低的问题,设计了一种基于无线传感网络的井下定位系统。系统硬件利用无线传感网络,优化了传感器与控制器;系统软件在IAREW8051环境内开发,利用质心定位算法,实现井下人员位置的精准获取。通过实验分析的方式,确定基于无线传感网络定位系统的有效性,进行井下定位工作时,具备较高的定位精度。

To solve the problem of low precision of traditional positioning system, a new positioning system based on Wireless sensor network is designed. The hardware of the system optimizes the sensors and the controller by using the Wireless sensor network;the system software is developed in the IAR EW8051 environment, using the centroid localization algorithm to achieve the precise acquisition of the position of the underground personnel. Through experimental analysis, the validity of the Wireless sensor network based positioning system is determined, and it has higher positioning accuracy when the underground positioning is carried out.
