Title: TIME SYNCHRONIZATION METHOD AND DEVICE
Abstract:
Embodiments of the present application provide a time synchronization method and device. The method comprises: a first device generates a first time synchronization frame according to a first encoding mode, the first time synchronization frame comprising a first frame header and a first time of day (TOD), the first frame header carrying an identifier of the first encoding mode, and the first encoding mode defining a boundary of the first time synchronization frame and a location of the first TOD in the first time synchronization frame; the first device sends the first time synchronization frame to a second device by means of a first single line, so as to trigger the second device to identify the first time synchronization frame according to the identifier of the first encoding mode, obtain the first TOD from the first time synchronization frame, and track the time of the first device according to the first TOD. The time synchronization method and device in the embodiments of the present application can save line resources.
