Title: DATA PROCESSING METHOD AND RELEVANT DEVICE
Abstract:
The embodiments of the present invention disclose a data processing method and a relevant device for improving the accuracy of a system time difference between time systems in a time synchronization system. The method in the embodiments of the present invention comprises: a host acquiring a moment T2 from a control command, wherein the moment T2 is a moment when a first device sends a first signal to a second device, and the first signal is a signal with the air duration for transmitting the first signal in a wireless channel being a fixed duration; the host receiving first data sent by the second device and carrying a moment T3, wherein the moment T3 is a moment when the second device receives the first signal sent by the first device; and according to the moment T2, the moment T3 and a pre-set △IR, the host determining a system time difference between time systems respectively corresponding to the first device and the second device, wherein the △IR is the fixed air duration for the first device to send the first signal to the second device.
