Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing:

[0030] In the present invention, the star-shaped short-wave radio network includes a short-wave radio station located at a central node and Q short-wave radio stations located at peripheral nodes, where Q is a natural number greater than 1, and each short-wave radio station located at a peripheral node forms a short-wave radio station located at a central node. Two-way wireless communication connection. In the embodiment of the present invention, 4 short-wave radio stations located at peripheral nodes are taken as an example for illustration, refer to figure 1 , is a schematic diagram of the overall structure of the star-shaped shortwave radio station network in the embodiment of the present invention. In the star-shaped shortwave station network of the embodiment of the present invention, the central node is represented as a B node ( figure 1 Indicated by B), and the fou...

Abstract

The invention belongs to the technical field of communication clock synchronization of short-wave radio station networks, and particularly relates to a clock synchronization method of a star type short-wave radio station network. The method comprises specific steps as follows: in each synchronization cycle, each peripheral node sends a polling data packet to a central node, and a clock count value when each peripheral node sends the polling data packet is recorded; a clock count value when the central node receives each polling data packet is recorded, and an acknowledgement data packet is sent to each corresponding peripheral node; a clock count value when each corresponding peripheral node receives each corresponding acknowledgement data packet is recorded, and a time deviation value of each peripheral node and the central node is acquired; after each synchronization cycle is ended, the clock count value of each peripheral node is adjusted, and q short-wave radio stations located at the peripheral nodes and a short-wave radio station located at the central node are synchronized.

Description

technical field [0001] The invention belongs to the technical field of shortwave radio network communication clock synchronization, in particular to a clock synchronization method for a star-shaped shortwave radio network. Background technique [0002] In recent years, due to the rapid development and maturity of radio communication technology, embedded computing technology and integrated circuit technology, it has become a reality for shortwave radio stations to be organized into radio station networks through wireless links. Clock synchronization is an important supporting technology in wireless ad hoc networks. Applications such as communication between nodes, implementation of frequency hopping technology, collaborative work, and data interaction require nodes in the network to maintain a unified clock. For example, in target tracking applications, Outstation sensor nodes send information such as the position and time of the monitored moving target to the central node of...
