摘　　要：为了满足面向室内定位中基站部署的优化设计需求,该文设计了一种测距型基站布网优化系统,研究和提供了室内基站定位优化部署模型。依据读入的基站配置信息,提供基站最佳部署方案,实现最优化基站部署,满足定位精度等性能要求,支撑室内定位、位置服务等业务应用的顺利实现。根据系统设计的基站最优化部署模型,研究了平面设置2~4个基站条件下的定位精度变化规律,得到最优化部署原则。结果表明,对于平面设置2个基站的情况,基站与观测中心间夹角90°或270°时,基站正交分布为最优部署;对于平面设置3个基站的情况,基站与观测中心间夹角120°时,基站围绕观测中心均匀分布为最优部署;对于平面设置4个基站的情况,基站与观测中心间夹角90°时,基站围绕观测中心均匀分布为最优部署。In order to fulfill the requirements of the optimal layout of base stations in indoor positioning,this paper provided an optimized distribution model of base stations,and designed a networking optimization software.At first,the base stations’configuration information was input.Secondly,the optimal layout strategy was provided for the base stations distribution to realize the indoor positioning requirement such as positioning precision.Consequently,the indoor positioning,and other location services with the base stations were supported by the optimal layout strategy and networking optimization software.According to the optimal distribution model supplied by this work,the positioning precision distribution and variation over the service area were analyzed under the conditions of 2,3,and 4 base stations deployment.The results showed that,in the case of two base stations on a plane,the angle between the base stations around the observation center was suggested to be 90°or270°,and the orthogonal distribution was the optimal layout of the base stations;in the case of3 base stations on a plane,the angle between the base stations was suggested to be 120°;in the case of 4 base stations on a plane,the angle betweenthe base stations was suggested to be 90°.As the optimal layout,the base stations were evenly distributed around the observation center.
