摘要

摘要: 针对目前超宽带TOF井下精确定位技术中对称双边双向测距（SDS-TWR）方法测距效率低、扩展性差，多次回应非对称双边双向测距（ADS-TWR-MA）方法测距效率及定位系统容量仍有提升空间的问题，提出了多标签多锚节点同时测距（ADS-TWR-MTMA）方法。该方法在多次回应非对称双边双向测距（ADS-TWR-MA）方法的基础上，进一步复用非对称双边双向测距过程中的测距消息，可以让多标签与多锚节点同时进行TOF测距，在保证测距精度的前提下大大提高了测距效率和定位系统容量。在机车接近探测系统和精确定位系统中的应用验证了ADS-TWR-MTMA方法在测距消息条数、测距耗时及系统容量上均优于SDS-TWR方法和ADS-TWR-MA方法。

Abstract: In view of problems that symmetric-double-sided two-way ranging (SDS-TWR) method had low ranging efficiency and poor expansibility and there was still room for improvement in the ranging efficiency and positioning system capacity of asymmetric-double-sided two-way ranging multi-ack(ADS-TWR-MA)method in current ultra-wideband TOF underground accurate positioning technology, a method of asymmetric-double-sided two-way ranging multi-tag multi-anchor (ADS-TWR-MTMA) was proposed. On the basis of ADS-TWR-MA method, the method further multiplexes ranging message in asymmetric-double-sided two-way ranging process, so that multiple tags and multiple anchor nodes can be used for TOF ranging simultaneously. The method greatly improves ranging efficiency and capacity of positioning system under premise of ensuring ranging accuracy. The application in locomotive proximity detection system and accurate positioning system verifies that the ADS-TWR-MTMA method is superior to SDS-TWR method and ADS-TWR-MA method in number of ranging messages, ranging time and system capacity.
