摘　　要：现有移动终端算法易丢失信号,且定位精度低,无法在局域网状态下满足定位到店铺的商铺推销等增值服务的需求,为此,基于终端信号强度差值定位算法解决上述问题。不直接使用信号值,采用信息量很小的信号差值,减弱环境对信号传输造成的损耗,降低不同类型终端对接收性能造成的影响;只需现有终端的信号强度数据就可以精确定位,数据量小、精度高且不需安装额外的定位模块,降低生产成本,具有广泛的推广价值。The existing mobile terminal algorithm is easy to lose the signal,and the positioning accuracy is low,so it cannot meet the demand of new value-added services,such as the promotion of shops,etc.The algorithm based on the terminal signal intensity difference can solve the above problems well.The algorithm did not use the signal directly,but used the small signal difference,which reduced the loss caused by the environment and the impact of different types of terminals on the receiving performance.Only the signal intensity data of the existing terminal were needed to achieve the accurate positioning.The precision is high,and the positioning cost do not need to be installed,which greatly reduces the production cost and has wide popularization value.
