MASTER CLOCK DEVICE, SLAVE CLOCK DEVICE AND TIME SYNCHRONIZATION METHOD

摘要

The present application belongs to the field of artificial intelligence, and in particular, to a master clock device, a slave clock device and a time synchronization method. The master clock device provided in the present application is configured to provide a clock time for a slave clock device, comprising: a first clock unit configured to provide a first master clock time on the basis of a real-time clock signal; and a second clock unit configured to provide a second master clock time on the basis of a time included in first positioning data in a satellite signal or on the basis of the real-time clock signal. The present application further provides a method for accurate synchronization between a master clock device and a satellite time, and a method for time synchronization between the master clock device and various slave clock devices. The solutions provided in the present application can eliminate the negative impact of time hopping on a time-sensitive part of an application system, whilst ensuring that the application system has a time following the real world, which is particularly applicable to applications such as self-driving of smart vehicles and automatic operations of robot systems.
