摘　　要：近年来,超宽带定位技术的快速发展,基于超带宽的定位系统被广泛应用于工业生产管控系统中;由于无线定位系统覆盖范围大、涉及场景多,所以需要根据工程实际情况将系统划分为多个定位区域,每个定位区域内分别完成定位,最后由系统完成区域结果的仲裁和切换;如果区域切换处理不当,会影响整个定位系统的性能效果,制约了无线定位系统的进一步推广;针对基于超带宽技术的多区域定位系统中的这个问题,设计了一种区域切换方法及相关流程,实现了区域切换的有效性、准确性以及实时性,并在实际的工程项目中进行了实测,测试结果顺利通过工程验证(定位频率为5 Hz,“切入”次数门限值为2,“切出”次数门限值为-2),满足工程需求,为多区域定位系统的设计提供了有效手段。In recent years,with the rapid development of the Ultra Wide Band(UWB)locating technique,the UWB locating systems are widely applied in industrial production control systems.Consequently,due to the covering large range and many scenes of wireless locating systems,it is necessary to divide the system into the multiple positioning areas according to the actual engineering situation.Each positioning area is separately carried out,finally,the system arbitrates and switches the regional results.If the area switching was handled improperly,it would affect the performance of the whole locating system and restrict its further promotion.Aiming at this problem,based on the UWB multi-area locating system,an area switching scheme is proposed,which realizes the effectiveness,accuracy and instantaneity of the scheme,by the practical engineering project test,the test result is verified by the engineer project(5Hz of location frequency,2 of switch-in counting threshold,and-2 of switch-out counting threshold),which meets the engineering requirements,and It provides an effective method for the regional positioning system design.
