Wireless synchronization method and system

Abstract

The invention discloses a wireless synchronization method and system. The wireless synchronization method comprises that a master wireless device respectively builds connections with slave wireless devices needing synchronization; the master wireless device stores the MAC addresses and corresponding connection verification information of the slave wireless devices; a time synchronization step comprises that the master wireless device sends connection requests and synchronization frames to the slave wireless devices according to the stored MAC addresses of the slave wireless devices; the slave wireless devices update own clock information according to the synchronization frames sent by the master wireless device and then disconnect with the master wireless device immediately; a synchronization control step comprises that the master wireless device sends control instructions to the slave wireless devices; after the slave wireless devices receive the control instructions, the slave wireless devices disconnect with the master wireless device immediately and execute the instructions. The wireless synchronization system is used for applying the wireless synchronization method. The system comprises a master wireless device and at least two slave wireless devices. The method and the system are the synchronization realization mechanism of an application layer and are rapid in realization and low in synchronization power consumption. The method and the system can be widely applied in the field of wireless synchronization as the wireless synchronization method and system.

Description

technical field [0001] The present invention relates to the field of wireless synchronization, in particular to a wireless synchronization method and system. Background technique [0002] The development of science and technology and the needs of social life promote the rapid development of wireless communication technology and apply it to various fields. Wireless communication technology is a communication method that uses the characteristics that electromagnetic wave signals can propagate in free space for information exchange. It solves the problems of weak scalability of wired communication, difficult construction, high cost, and cable restrictions. The 802.11 standard is a wireless local area network standard formulated by the IEEE. It mainly specifies the physical layer (PH) and the medium access control layer (MAC) of the network, among which the regulation of the MAC layer is the key point. Wireless communication technologies based on IEEE802.11 include WIFI, Bluet...

AI Technical Summary

Problems solved by technology

Wireless communication technology has a certain number of connections and synchronization difficulties, but in many application fields it is necessary to break through the number restrictions and synchronization control requirements, so a variety of synchronization mechanisms and methods have been proposed, but these synchronization methods are based on the first wireless device As a benchmark, other wireless devices synchronize based on the first wireless device, which requires connection maintenance and physical layer implementation

When the demand for synchronization accuracy is not large, this approach is very power-hungry
