Realization of Bidirectional Communication Positioning Base Station Based on UWB and SUB-GHz

在智能供电站、官网隧道、石化工厂、智慧施工、体育训练和司法监狱等室内设施复杂的应用领域,传统定位基站对复杂区域尤其是工业领域等存在三维感知需求方面存在一定的短板,不能很好地表现精细定位。因此,提出了一种基于超宽带(UWB)和SUB-GHz技术相融合的双向通信定位基站的方案,在无线通信方面主要采用DW1000和SI4438射频芯片,配套对应的定位标签和定位引擎,以实现对复杂区域的定位感知和分层分区,为客户提供智能化、精细化管理及更多智能化业务的创新。实验数据表明,基于UWB和SUB-GHz双向通信的定位基站可以很好地实现对三维的感知,达到预期效果。

In the application field of complex indoor facilities such as intelligent power supply stations,official network tunnels,petrochemical plants,intelligent construction,sports training and judicial prisons,the traditional positioning base station has some shortcomings in terms of the demand for three-dimensional perception of complex areas,especially industrial areas,and it can not perform fine positioning very well.Therefore,a bi-directional communication positioning base station scheme based on the combination of UWB and SUB-GHz technologies is proposed.In wireless communication,DW1000 and SI4438 radio frequency chips are mainly adopted,and corresponding positioning tags and positioning engines are equiped to realize positioning awareness and hierarchical division of complex areas,and provide customers with intelligent,refined management and more intelligent business innovation.The experimental data shows that the positioning base station based on UWB and SUB-GHz bidirectional communication can well realize three-dimensional perception and achieve the desired effect.
