Problems solved by technology

according to image 3 As shown, every time each meter reading message passes through one more PCO site during transmission, the PHY layer needs to receive the DATA layer for processing and forwarding, and the meter reading message is sent and responded according to the original path, which is a waste of time. Consume resources
In the actual scenario, the communication quality between the site with TEI of 8 and the CCO is actually very good, but the site with TEI of 8 chooses the site with TEI of 2 as its relay site, and then copies it. When the table is used, it will cause waste of air interface transmission, long acquisition cycle, and low efficiency.

Embodiment 1

[0112] Embodiment 1: This embodiment is a preferred embodiment of the broadband micropower wireless intelligent meter reading initial routing structure of the present invention. See Figure 8 and Figure 9 ( Figure 8 Represents the CCO initial routing construction flow diagram, Figure 9 A STA initial routing construction flow chart), the route construction method of the present embodiment includes the routing structure of the CCO and the routing of the STA:

[0113] CCO routing structure:

[0114] 1) After the CCO is powered on, obtain the MAC address, configure the white list, broadcast beacon frame and network notification packets, and wait for the receiving site request to enter the network;

[0115] 2) After the CCO receives the request to enter the network, parse the MAC address and routing relationship in the message and assign TEI;

[0116] 1) CCO determines whether the network maintenance message sent by the Network Maintenance Timer is turned on if the network maintenance t...

Embodiment 2

[0130] Example 2: This embodiment is a preferred embodiment of a proxy change request for broadband micro power wireless intelligence of the present invention, see Figure 10 ~ 13 .

[0131] 1) Site timing traversal route in the table is better than the current path, if there is existence, pick it out, such as the sort table is waiting for sorting;

[0132] 2) Site for sorting and starting from 1 setting equal level value, selecting the smallest level value as the new route, the number of the same level value exceeds 5, then select 5 paths.

[0133] 3) Site Select new route, construct and initiate a proxy change request message, wait for the receiving agent change request confirmation message;

[0134] 4) After the CCO receives the proxy change request message, parses the new agent site and the old site carried in the message, and determines if the proxy changes are allowed. If allows, select a new agent site constructor change request confirmation result field to fill in 1 And sen...

Embodiment 3

[0137] Example 3: This example is a network topology after the broadband micro power wireless smart meter meter agent change is completed, see Figure 12 . This network topology is only used to illustrate the method of applying the agent change of the intelligent meter reading network of the present invention, and is not limited to the application scenarios of the present invention, which will apparent to those skilled in the art. Compared Figure 7 The network topology and network topology after the start of the network Figure 13 Complete the network topology after the agent, add a compact, large number of PCOs between sites, reduce the level of the site, so that the efficiency of the meter reading and reduces the congestion transmitted in the null.

Abstract

The invention relates to a method for forming a cluster network based on proxy change, and belongs to the technical field of wireless communication. The method comprises the following steps: S1, a CCO forms a whole network topology and establishes an initial route; S2, a station establishes an initial route; S3, the station actively initiates a proxy change request message; S4, the CCO receives the proxy change request message, updates network topology and routing information, and constructs a proxy change confirmation message; and S5, the station receives the proxy change confirmation message and updates the routing information. According to the invention, the hierarchies of the station are reduced through a proxy change method, a cluster network is formed, and the network topology is more compact, so that the number of relay stations required when the information of the station is acquired is reduced, the time overhead and the number of downlink messages are reduced, and the acquisition efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of wireless communication, and it is directed to a method based on a proxy change to form a cluster network. Background technique [0002] The smart meter reading technology in the user's electricity message collection system includes two types of limited networks and wireless networks. The amount of wired network wiring is large, the broadband is increasing, causing the linear and closer, and the solid line is easy to damage, a little Error has to change the whole line, and it is more difficult to maintain it. The wireless transmission network avoids the difficulty of wiring and is more simple, and the networking is more flexible, and the network is self-organized. Therefore, the system uses a wireless transmission. [0003] In order to realize the user's electricity information acquisition system, rapid collection, processing, and real-time monitoring of power users' power information, thereby proposing a proxy s...
