The invention provides a positioning system time synchronization adaptive adjustment method and a positioning system and relates to the technical field of an ultra wideband. The ultra wideband positioning system comprises a control end and a receiving end. The control end sends a clock signal to the receiving end, so the receiving end carries out time synchronization according to the clock signal.Time deviation between the receiving end and the control end is determined by the control end. The receiving end carries out the time synchronization according to the time deviation. Through application of the adaptive adjustment method in the embodiment of the invention, the time deviation between the receiving end and the control end can be determined by the control end; and in a clock synchronization process, the delay between the control end and the receiving end can be determined according to the time deviation. The line length between the control end and the receiving end does not needto be determined, so a delay determination process in the clock synchronization process is simplified, the clock synchronization efficiency is improved, and certain fixed delay exists between the receiving end and the control end.
Description
technical field [0001] The present invention relates to the technical field of positioning systems, in particular to a positioning system time synchronization adaptive adjustment method and a positioning system. Background technique [0002] In an ultra wideband (Ultra Wideband, UWB) positioning system, clock synchronization needs to be performed on each positioning base station to improve positioning accuracy. However, each positioning base station needs to determine the line length between the positioning base station and the synchronization controller when performing clock synchronization with the synchronization controller. For a positioning system with a complex structure, the process of determining the line length is very cumbersome. Contents of the invention [0003] In view of this, the present invention provides a positioning system time synchronization adaptive adjustment method and a positioning system. [0004] The technical scheme provided by the invention i...
