Flow management method based on synchronization system

Abstract

The invention discloses a flow management method based on a synchronization system, which comprises the following steps: in a star network, periodically issuing a synchronization signal to each terminal through a centralized controller for the terminal to calibrate and update, and dividing time into different time slots, namely, the start and the end of all communication have predictable start and end time points. The conflict probability is reduced, the stability and controllability of communication are guaranteed, the time slots are distinguished, the requirements of two-way communication are met, the scheduling management of high-priority equipment and low-priority equipment on communication opportunities is also met, and meanwhile, through the arrangement of the uplink non-competitive sub-time slots, the data is transmitted or the transmission is abandoned according to the management strategy, the transmission opportunity is increased for each terminal in each time slot, the channel waste is avoided, and the terminal equipment in the current time slot or different time slots does not compete.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a traffic management method based on a synchronization system. Background technique [0002] Wireless communication technology has developed rapidly in the recent period; although many important communication systems still use wired connections, in many non-critical applications, wireless communication is becoming more and more popular because of its convenient installation and little impact on the deployment environment. The more it is adopted; for example, in smart home systems, through wireless networking technologies, such as ZigBee, Thread, Bluetooth Mesh, different household appliances are interconnected, and users can connect sensor lights, smart sockets, Sensors and other devices can be powered, that is, an intelligent control network can be established without laying communication cables in advance; or after the household appliances embedded with wireless ...

[0002] Wireless communication technology has developed rapidly in the recent period; although many important communication systems still use wired connections, in many non-critical applications, wireless communication is becoming more and more popular because of its convenient installation and little impact on the deployment environment. The more it is adopted; for example, in smart home systems, through wireless networking technologies, such as ZigBee, Thread, Bluetooth Mesh, different household appliances are interconnected, and users can connect sensor lights, smart sockets, Sensors and other devices can be powered, that is, an intelligent control network can be established without laying communication cables in advance; or after the household appliances embedded with wireless intelligent controllers are powered on, the controllers can automatically connect to the wireless network, at any time Receive the user's control at home or remotely; although wireless communication is very convenient, and the network can be quickly established through advanced networking technology, but compared with traditional wired connections, there is a certain communication failure rate; wired connection technology is based on Each cable is equivalent to a dedicated line connection to uniformly connect the controlled device to the master device; the communication between the master device and a controlled device will hardly be affected by other controlled devices; The openness of the medium, when the master control device communicates wirelessly with a certain controlled device, the wireless reception of other controlled devices will also be affected; if multiple devices initiate wireless communication at the same time, the wireless signals will interfere with each other at the receiver , leading to communication failure; therefore, there is an urgent need to solve the above technical problems based on traffic management methods in synchronous systems
