Embodiment
A kind of two-way alternate communication method based on G3-PLC, it comprises the following steps：
Step 1：Mesh network networking, form the netted topological network of multi-hop；
Step 2：Lightweight demand distance vector routing algorithm of future generation is used in the netted topological network of multi-hop, is established two-way
Dynamic routing.
Mesh network networking described in step 1, forms the netted topological network of multi-hop, and its step includes：
Step 1.1 concentrator G3-PLC modules power-up initializing simultaneously creates a subnet, and it is as follows to create process：
(1) concentrator module electrification reset；
(2) concentrator sets the network identifier (subnet identifier) of primary module, and network identifier is defined as two bytes,
And it can not repeat.
(3) it is hexadecimal 0000 that primary module, which sets the module device indications of oneself,.
(4) self-administered ammeter archives are handed down to concentrator module by concentrator, form " the white name of concentrator module
It is single ", wherein ammeter archives must include electric meter address, and ammeter state is all engineering noise when initial, as follows：
(5) primary module creates subnet, waits slave module to initiate registration.
(6) when there is slave module to register, check whether the table address of the corresponding ammeter carried during slave module registration is reflecting
In firing table, as illustrated if, the table is one piece of table that this concentrator is responsible for, and receives application and by module corresponding to table address
Device identifier distributes to slave module, and connection status is changed to " activate " from default conditions " effective ".Otherwise refuse slave module to add
Subnet application.
Electric current journey initializes in step 1.2 slave module, and initialization flow is as follows：
(1) slave module electrification reset.
(2) slave module scanning subnet, overall network identifier is found, the best PAN nets of selection signal first add, such as quilt
Refusal will continue to select other PAN nets to add, such Xun rings.
(3) ammeter or device address initiate to add subnet application corresponding to slave module carrying.
(4) after adding subnet, primary module distributes a module device identifier (two bytes) and gives slave module, slave module root
According to network identifier and device identifier unique mark oneself.
It is double using the foundation of generation lightweight demand distance vector routing algorithm in the netted topological network of multi-hop described in step 2
To dynamic routing, its step includes：
Step 2.1 concentrator G3-PLC modules realize that lightweight demand distance vector route of future generation is calculated in 6LOWPAN layers
Method；
G3-PLC realizes lightweight demand distance vector routing algorithm of future generation in 6LOWPAN layers, and routing algorithm includes
Neighboar lists, routing table and route requests table；Neighboar lists have recorded the adjacent node that can be physically communicated with present node
Information, routing table, which have recorded present node, will reach destination node, the information such as address for the next-hop node to be passed through, route
Required list is interim table, for finding route and for keeping the tracking of certain route querying message.
Step 2.2 establishes two-way dynamic routing stage by stage；
1st stage：Route requests
Routing request packet (claiming RREQ afterwards) refers to a broadcast packet sent from source node S, if intermediate node receives,
Intermediate node will re-broadcast it once, and so repeatedly, until it reaches destination node D, route requests process is as follows：
(1) source node S produces a new RREQ message, and is broadcasted its neighbor node；
(2) if neighbor node finds there is route requests ID and source address all identicals in its route requests table
RREQ, then this RREQ message is abandoned, on the contrary this node will insert the RREQ message in route requests table, while
A routed path to origin node is created in routing table to record, and is then re-broadcast this RREQ message by the neighbor node
Go out；
(3) other intermediate node repeat step (2) steps；
(4) after destination node D receives this RREQ message, it will be checked whether in its corresponding route requests table
With the presence of route requests ID and source address all identical RREQ message, the routing cost if then comparing this two RREQ message
(there is the weak tendency link total number of cost=forward direction route cost+process on road), it is preferential relatively more preceding to route cost, if forward direction is route
Cost is identical, then the small routing cost of the weak tendency link total number passed through is smaller, if the latter's routing cost is smaller, will update the former
Forward direction route cost and process weak tendency link total number, retain the former if the latter's routing cost is bigger, i.e., route is kept
Optimal path, and the reverse route address in destination node routing table is updated simultaneously；
Second stage：Route replies
Route replies bag (claiming RREP afterwards) refers to a unicast packet sent by destination node D, by intermediate node along
Accessed path is forwarded to source node S, and route replies process is as follows：
(1) intermediate node receives unicast packet, checks the road whether having in the routing table of the intermediate node to source node S
Footpath, if abandoning this RREP message without if；
(2) whether intermediate node checks route requests ID and source address all identical RREP in its route requests table, if
This RREP message is not abandoned then, intermediate node compares the reverse route cost of this two RREP message if having, if after
Reverse route cost in person RREP more then abandons the RREP greatly, otherwise the reverse route cost in renewal route requests table, and
The RREP message is forwarded to its route requests table and route requests ID and source address all identical Message Records by the intermediate node
Reverse route address where node；
(3) if the link that at the same time RREP is passed through is weak tendency link, need to be passed through in the weak tendency link of the RREP message
Cross on the basis of bar numerical value plus 1, and the RREP is forwarded back on the path of source address from destination address, the value of reverse route cost
Hop-by-hop is cumulatively added, last intermediate node according to RREP in its routing table plus one its to destination node path record；
Now, source node S can actively send packet with destination node D and reach opposite end, i.e. source by this paths
Node S has the path to source node S into the routing table of the destination node D intermediate nodes passed through, also has to destination node D's
Path, therefore two-way dynamic routing is established, realize bi-directional data real-time interactive.Application in AMRS include with

Whether host node checks has in routing table to the path of the purpose ammeter, and amr frame is forwarded if having to the path
Next-hop node, if carrying out route discovery without if, purpose table path is arrived in foundation, and forwarding is given to the next-hop section in destination node path
Point.
Step 4.1.3 next-hop nodes check whether purpose table address is identical with Self address, and circulation is until amr frame arrives
Up to purpose ammeter：
Next-hop node receives the amr frame of host node forwarding, checks whether purpose table address is identical with Self address, if
It is identical, table where oneself is transmitted to, next-hop node is forwarded to if different.Circulation is until amr frame reaches purpose ammeter.

The path of host node, amr frame is forwarded, if carrying out route discovery without if, to be established to the next-hop node in the path to master if having
The path of node, after the completion of path is established, relay to the next-hop node for reaching host node path；
Step 4.3.2 next-hop nodes are reported to event packet up to concentrator：
After next-hop node receives the reporting events packet for wanting the ammeter node forwarding of reported event, purpose section is checked
Whether dot address is identical with the address of oneself (i.e. whether oneself is host node), and reporting events packet is passed through into this if identical
Ground serial ports is transmitted to concentrator, and next-hop node is forwarded to if different, and circulation repeatedly, collects until reporting events packet reaches
Middle device.
