Problems solved by technology

[0004] However, ultra-broadband has the characteristics of high transmission rate and short communication distance, which is not suitable for long-distance high-speed wireless communication; in addition, through the node communication of wired connection, each node needs to be connected to the synchronization controller by cable, and the line planning becomes complicated. , there are defects such as high deployment cost, poor scalability, and poor flexibility

Abstract

The invention relates to the field of ultra-wideband wireless communication, and discloses a self-adaptive networking time synchronization system based on ultra-wideband wireless communication. The system comprises at least one master node and at least one slave node, and is characterized in that the sending time of the master node is taken as the basis, and in order to prevent conflict of the sending time of different nodes, the sending time of other slave nodes takes a local identifier as the criterion; the other slave nodes adaptively select the synchronized nodes to perform time synchronization according to a level principle, a reliability principle and a distance principle in the system, and after the slave nodes and the synchronized nodes finish time synchronization, synchronizationinformation is sent to the adjacent nodes until all the nodes finish synchronization. The invention also provides a self-adaptive networking time synchronization method based on ultra-wideband wireless communication. The limitation of a node communication system in wired connection is broken through, nodes can be arranged at will, the flexibility and convenience of node arrangement and the precision of time synchronization are improved, and application is wide.

Description

technical field [0001] The invention relates to the field of ultra-wideband wireless communication, in particular to a time synchronization system and method based on adaptive networking of ultra-wideband wireless communication. Background technique [0002] With the continuous development of communication technology, the requirements for accurate and reliable communication are getting higher and higher. In a communication network, time synchronization is required between nodes. If the time synchronization is not handled properly, the success rate of transmission between nodes will be low or the connection will be disconnected directly, which cannot meet the business requirements of ultra-broadband. [0003] In current technology, such as figure 1 As shown, in order to improve the reliability of time synchronization, wired synchronization is usually used between nodes, and the synchronization controller is used to transmit time information to each node through wired communi...
