摘　　要：针对高密度部署的实时定位系统(Real-Time Locating Systems,RTLS)中对于动态业务的新节点接入场景,提出了一种基于泊松分布的高密度RTLS新节点接入方法。监听区域内所有可用的业务信道信息,利用泊松分布模型计算可用业务信道在单位时间内拥有足够新节点接入时间的概率,根据可用信道表完成新节点接入。仿真结果表明,新节点接入后的平均信道利用率可达到40.08%。所提方法对系统中原有业务的影响较低,且新节点接入后的信道利用率较高。For the new node access scenario of dynamic services in the high-density deployment of real-time locating systems(RTLS),a high-density RTLS new node access method based on Poisson distribution is proposed.Poisson distribution is used to calculate the probability that the available service channel has enough new node access time per unit time by monitoring all available service channel information in the area,and completes the new node access according to the available channel table.Simulation results show that,the average channel utilization after the new node is connected can reach 40.08%.It has a lower impact on the original business in the system,and the channel utilization rate after the new node access is higher.
