METHOD AND DEVICE FOR ENERGY-SAVING EXTERNAL SYNCHRONIZATION OF CLOCKS IN A DISTRIBUTED REAL-TIME COMPUTER SYSTEM

摘要

A kind of method of the present invention is used for an external time reference of the node computer in distributed real-time systems of synchronous clock, such as GPS time, needs the smallest energy consumption, and for constructing sparse time reference. By considering the cycle of oscillation of the local oscillator of physical environment parameter variations influence, the section remained in office when must occur according to these external syncs, can dynamically determine that frequency can be significantly reduced with the outer synchronization process of energy intensive.
