The invention provides a positioning base station clock synchronization calibration method and device, and relates to the technical field of positioning. The method comprises the following steps of: obtaining clock information T0 when the main positioning base station sends a first clock synchronization signal, receiving clock information Ti when the first clock synchronization signal is receivedfrom the positioning base station, the main positioning base station receives clock information t0 when receiving a third-party signal; the slave positioning base station receives clock information tiwhen the third-party signal is received, the third-party signal is sent by third-party equipment; based on T0, Ti, t0 and ti, determining a measurement distance difference between the third-party device and the slave positioning base station and a measurement distance difference between the third-party device and the master positioning base station, and determining a system clock difference between the master positioning base station and the slave positioning base station based on the measurement distance difference, the system clock difference being used for synchronizing a system clock of the slave positioning base station. The clock synchronization calibration method and device can reduce the complexity and cost of clock synchronization calibration of the positioning base station.
Description
technical field [0001] The present disclosure relates to the field of positioning technology, and in particular, to a method and device for clock synchronization calibration of a positioning base station. Background technique [0002] The positioning base station refers to the radio transceiver station that transmits information with the positioning terminal in a certain radio coverage area. With the development of communication technology, positioning base stations have been widely used in a variety of positioning scenarios, and in order to reliably interact with other positioning base stations and provide related services for positioning terminals, it is necessary to monitor the system clocks of multiple positioning base stations. Perform synchronization calibration. [0003] In the prior art, multiple positioning base stations can be connected to a dedicated clock signal generator, and each positioning base station receives the clock signal sent by the clock signal gener...
