Self-adaptive clock synchronous system

Abstract

The invention discloses a self-adaptive clock synchronous system which comprises a main service layer, a secondary service layer and a client layer, wherein the main service layer comprises one or more main time servers; the main time servers are externally connected with an atomic clock; the secondary service layer comprises a plurality of secondary time servers; one part of secondary time servers and the main time servers are subjected to time synchronization; the other part of secondary time servers are mutually subjected to time synchronization; the client layer comprises a plurality of terminals; and the terminals are used for sending time synchronization requests to the secondary time servers to carry out time synchronization. According to the invention, when a reference time source goes wrong, a suitable time source can be automatically searched, so that the system automatically completes the configuration of a synchronization network and the time synchronization network has sufficient stability and robustness and has strong self-adaptive capacity; and meanwhile, a self-adaptive clock synchronous system has higher safety. The self-adaptive clock synchronous system adopts a hierarchical system structure, has clear layers and clear layout as well as strong expandability and is suitable for growth of services.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an adaptive clock synchronization system. Background technique [0002] With the development of the times and the advancement of society, as well as the popularization of computers and communication networks, information technology and network technology have become more and more widely used in various fields, many of which require high-precision and high-reliability time synchronization. However, in practical applications, the clock of the computer is too unstable and is easily affected by external environments such as temperature and power. The computer clock is composed of a software clock and a hardware clock. Due to the physical performance of the clock itself and the influence of external factors, the punctual performance of the two clocks cannot meet the demand. However, with the rapid development of computer and network technology, there are more and more time-...
