摘　　要：在CC2431定位实践应用中,基于三角加权质心定位,硬件部署不易实现,精度不能满足实际的需要.文章使用四点定位方法,对算法进行了可行性的优化,解决了基于三角加权质心定位不精确的问题.改进后的方法在实现二维定位的同时提高了定位精度.Based on triangular weighted centroid localization and hardware deployment easy,the positioning accuracy of CC2431 position cannot meet the actual needs in practical application.Using four point positioning method,the feasibility of locating algorithm optimization for CC2431 positioning,which solves the inaccuracy based on triangular weighted centroid localization issues.This improved method not only fit the two-dimensional location,but also improve the positioning accuracy.
