Title:
TIME SYNCHRONIZATION SYSTEM, LEARNING DEVICE, INFERENCE DEVICE, AND TIME SYNCHRONIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/075276
Kind Code:
A1
Abstract:
In the present invention, a model learning unit (401) executes a learning process for estimating the time-of-day of a grand master from time synchronization information of a subgrand master. An inference unit (402) estimates, using a trained model obtained through the learning process, the time-of-day of the grand master from the time synchronization information of the subgrand master. A synchronization control unit (204) performs time synchronization in accordance with an acquired time-of-day when the time-of-day is acquired from the grand master, and performs time synchronization in accordance with the time-of-day estimated by the inference unit (402) when the time-of-day is not acquired from the grand master.
