A multi-terminal access method based on wifi230mhz

Abstract

The invention relates to a WIFI230MHz-technology-based multi-terminal access method. The method comprises: S1, registration of all terminal information in a single unit network is carried out and an AP determines the number of terminals, data contents of the terminals, and access priorities in a network under jurisdiction according to a terminal information registration table; S2, a group of terminals initiate access applications carrying ID information of terminals, and the AP searches the access priorities and data contents of the terminals based on the terminal ID information and distributes proper time slices; S3, the polled terminal carries out data information interaction with the AP within the distributed time slice, and connection with the AP is released after ending of the time slice; S4, after releasing of connection of the group of terminals, a next group of terminals are connected to the AP and data interaction is carried out according to an equal flow; and S5, the AP is connected to terminals in the network circularly according to the terminal information registration table and updates interactive terminal information continuously, so that the network works in real time. Therefore, instability of the system due to multi-terminal competition can be avoided.

Description

technical field [0001] The invention relates to the field of wireless communication equipment, in particular to a WIFI230MHz-based multi-terminal access method. Background technique [0002] In recent years, WIFI technology based on the IEEE802.11 standard group has been developed and applied very fast, and has a complete industrial chain and low construction costs. 230MHz is the frequency band used in my country's energy, forest and other fields. On the stage of energy Internet and other network construction needs, WIFI technology has the opportunity to be more widely used. At present, WIFI technology is mainly used in the scenario of local area network and a small number of terminal access, while the WIFI 230MHz technology based on Energy Internet should be applied in the scenario of wide coverage and a large number of terminals. If the competitive access method of WIFI technology is copied, it is difficult to ensure stable access of multiple terminals. [0003] At prese...

AI Technical Summary

Problems solved by technology

The competition mechanism is applied to WIFI230MHz with wide coverage, multiple terminals, and data bandwidth rules. , leading to a limited number of access terminals; 2. In the competition mechanism, the terminal communication bandwidth depends on the number of access terminals and their own channel quality, and terminals with poor channel conditions cannot guarantee stable communication
