RSSI Improved Localization Algorithm in Train Blind Location based on ZigBee

为了能够对隧道内行驶的列车进行全程实时定位、弥补卫星导航定位系统存在定位盲区的不足,提出了基于Zig Bee技术的RSSI改进质心定位算法和改进加权质心定位算法,并利用Zig Bee系统芯片CC2530组建了无线传感器网络,完成了软硬件设计与实现,最后通过实验验证了该算法的可行性.

In order to real-time positioning of train tunnel driving to make up for the inadequacy of existing positioning satellite navigation and positioning system blind area,the RSSI improved centroid localization algorithm is proposed based on Zig Beetechnology and improving the weighted centroid localization algorithm,and the Zig Bee system chip CC2530 is used to form the wireless sensor network（ WSN）. The design and implementation of hardware and software are completed,and the feasibility of the algorithm is verified by experiment.
