摘　　要：当前分布式无线通信系统数据采集节点定位的数据搜索模式呈现单向性,导致节点定位极易中断,且信道储存容量较低,因此提出一种新的分布式无线通信系统数据采集节点自动定位方法。根据当前分布式通信系统数据的原始信息序列和数据源信息,构建最高积累分布函数,整合当前系统数据信息,降低信道占有率。建立BTREE索引,利用BTREE索引对当前整合数据进行双向搜索,调用当前通信系统的预设引擎数据接口创建数据序列,在时间重组序列表的驱动下,将采集数据引入通信系统静态存储器中,确定OE信号,将其先拉低再升高,明确比例关系,按照路径比例长度确定当前系统数据采集节点位置。实验数据表明,本文方法在进行节点定位时中断率始终维持在25%以下,信道储存容量高于传统方法11%,定位准确度始终在95%左右,具有实用性。At present,the data search mode of data acquisition node location in distributed wireless communication system is one-way,which leads to easy interruption of node location and low storage capacity of channel.Therefore,a new automatic location method of data acquisition node in distributed wireless communication system is proposed.According to the original information sequence and data source information of the current distributed communication system data,the highest accumulation distribution function is constructed to integrate the current system data information and reduce the channel share.Building BTREE index,BTREE indexes are used to search integration of the data bidireclional search for the curment intergration data,and the the default engine data interface of the communicution system is used to create data sequence.Driven by the time reorganization sequence table, the collected data is introduced into the static memory of the communication system to determine the OE signal, which is first pulled down and then raised, to clarify the proportion relationship, and to determine the current system data acquisition node location according to the path proportion length.Experimental data show that the interruption rate of the proposed method is always below 25%,the storage capacity of the channel is 11% higher than that of the traditional method,and the positioning accuracy is always around 95%.
