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

A kind of multiple terminals based on WIFI230MHz cut-in method

Technical field

The present invention relates to field of wireless communication devices, particularly relate to a kind of multiple terminals based on WIFI230MHz cut-in method.

Background technology

In recent years, WiFi technology based on IEEE802.11 standard group has obtained development and the application being exceedingly fast, and has possessed perfect industrial chain and relatively low construction cost.230MHz is the use frequency range in the fields such as China's energy, forest, and on the stage of the networking demands such as energy the Internet, WiFi technology has an opportunity to be more widely used.The scene that WiFi technology is mainly used in LAN at present, a small amount of terminal accesses, WIFI230MHz technology based on energy the Internet then to be applied in wide covering, the scene of great amount of terminals.If the contention access method indiscriminately imitating WiFi technology is difficult to ensure that multiple terminals is stably accessed.

At present, WiFi technology uses competition mechanism to process multiple terminals access request, first accesses with first requestor and channel width is preferentially assigned as accessing principle, as shown in Figure 1.Competition mechanism is applied on the regular WIFI230MHz of wide coverings, multiple terminals, data bandwidth, have a disadvantage in that 1, in competition mechanism, the terminal that channel condition is good is easily accessed and bandwidth-hogging, the very difficult access of terminal that channel condition is bad, causes number of access terminals limited；2, in competition mechanism, terminal communication bandwidth depends on number of access terminals and itself channel quality, and the bad terminal of channel condition can not ensure stable communication.

Summary of the invention

In view of this, it is an object of the invention to provide a kind of multiple terminals based on WIFI230MHz cut-in method, for polling access method, the systematic jitters that multi-terminal competition is brought can be avoided, to meet the demand that WIFI230MHz great amount of terminals accesses.

The present invention uses below scheme to realize: a kind of multiple terminals based on WIFI230MHz cut-in method, specifically includes following steps:

Step S1: registered by all end messages in individual unit network, AP is according to the terminal quantity in end message registration table, clearly linchpin lower network, the data content of terminal and the priority of access；

Step S2: a collection of terminal is initiated to access application, the id information with terminal is applied in accessing of described terminal, and AP searches access priority and the data content of terminal according to terminal ID info, distributes reasonable time sheet；

Step S3: the terminal being polled to is in the timeslice of distribution and AP interaction data information, after timeslice terminates, release and the connection of AP；

Step S4:AP, after the release of upper batch terminal connects, accesses lower batch terminal, returns step S2, by equal flow processing data interaction；

Step S5:AP, according to terminal in end message registration table circulation access network, constantly updates interactive terminal information, so that network is in a kind of real time operation.

It is also preferred that the left the access terminal of energy the Internet has does the network planning in advance, the structure of network and end message can be registered by computer network unification management completely.

In the application of energy the Internet, the data interaction of each terminal needs priority support, roll-call access mechanism proposed by the invention can preferably solve following problem: 1, in polling mechanism, as long as channel meets most basic communication condition, even the communication bandwidth that can be provided by is the least, as long as having suitable timeslice, also can completely interaction data.2, in polling mechanism, terminal quantity is unrestricted, and acquired bandwidth fluctuation is little, and communications status is stable.3, in polling mechanism, there is the terminal of registration all to have corresponding timeslice to access AP and carry out data interaction, it is to avoid the state to be accessed such as be constantly in.

Compared with prior art, present invention achieves WIFI230MHz technology and access the system availability of scene in multiple terminals, polling access method compares more original contention access method, can reach following remarkable result: 1, use polling access method, number of access terminals is unrestricted, can ensure that all terminals can timely and effective access network.2, the timeslice mechanism of polling access method can make all terminal energy and network carry out effective data interaction.3, polling access method can make wireless network bandwidth more effectively utilize, and improves the efficiency of operation of whole network.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.

The present embodiment provides a kind of multiple terminals based on WIFI230MHz cut-in method, as in figure 2 it is shown, specifically include following steps:

Step S1: registered by all end messages in individual unit network, AP is according to the terminal quantity in end message registration table, clearly linchpin lower network, the data content of terminal and the priority of access；

Step S2: a collection of terminal is initiated to access application, the id information with terminal is applied in accessing of described terminal, and AP searches access priority and the data content of terminal according to terminal ID info, distributes reasonable time sheet；

Step S3: the terminal being polled to is in the timeslice of distribution and AP interaction data information, after timeslice terminates, release and the connection of AP；

Step S4:AP, after the release of upper batch terminal connects, accesses lower batch terminal, returns step S2, by equal flow processing data interaction；

Step S5:AP, according to terminal in end message registration table circulation access network, constantly updates interactive terminal information, so that network is in a kind of real time operation.

It is also preferred that the left the access terminal of energy the Internet has does the network planning in advance, the structure of network and end message can be registered by computer network unification management completely.

The key point of the present invention is to introduce the polling access method of a kind of WIFI230MHz, by this method, improve the insoluble number of access terminals of original contention access method limited and access instability problem, to reach the realization in energy internet, applications of the WIFI230MHz technology.
