Description
Technical field
The present invention relates to a kind of networking technology, more particularly to a kind of power line carrier mould applied to power information collection
The network-building method of block, belong to power-line carrier communication field.
Background technology
Power line carrier communication is the technology that information transfer is carried out using existing power transmission line, and it is without wiring
A kind of inexpensive valid data communication mode.
At present, power-line carrier communication has in fields such as power information collection, smart home, wisdom street lamps and answered
With especially in power information collection field, the electric energy meter more than 80% is that power information is realized by the way of power line carrier
Upload.
In power information collection field, concentrator needs to carry out the electric energy meter in institute's compass of competency information gathering, electricity
Line of force carrier module just realizes writing to each other between concentrator and electric energy meter.In transmitting terminal, power line carrier module receives
The information of electric energy meter, and will be transmitted on modulates information to power line；In receiving terminal, power line carrier module will have from power line
Effect information, which demodulates, to be come, and transmits information to concentrator.Before power information collection is carried out, it is necessary to complete host node to from
The management of node, that is, host node and the networking from node are completed, also wants selected part from node as via node, to extend letter
The transmission range of breath.Due to the unstability of power line transmission channel, after networking completion, it is also necessary to which network is safeguarded
And reconstruct, to form a carrier communication network that can dynamically change network topology.
At present, more commonly used networking technology is a kind of dynamic routing networking technology based on flooding network, and the technology has
There is the features such as self-forming, self- recoverage, self-organizing, all nodes are full-function devices in network, and each node can do other
The relaying of node, it can communicate between any two node.So this latticed form is more flexible, but route technology is also relatively multiple
It is miscellaneous.
The networking initialization procedure of the dynamic routing networking technology based on flooding network, comprises the following steps：
In step 1, network from node, networking request signal is sent in the form of broadcast after the power-up, other nodes connect
Receive the signal increases this node address afterwards, and the signal is continued to forward, until host node receives the request signal；
Step 2, host node receive the broadcast singal sent from node, and select Optimization route, and are asked back networking
Complex information is sent back to from node by the Optimization route of selection, that is, completes the networking from node；
Step 3, host node set specific register to store selected Optimization route, between later stage master and slave node
The transmission of information will be directly completed using selected Optimization route, without selecting to route using the mode of flooding.
The network operation process of the dynamic routing networking technology based on flooding network, comprises the following steps：
On the path of Optimization route is chosen to be, all nodes are by periodic broadcasting heartbeat message, and current un-activation
Route on node need not then broadcast.Active node by broadcast heartbeat message notify its neighbor node it still locate
In state of activation.And receive the neighbor node of heartbeat message, i.e., think accordingly it with broadcast the heartbeat message neighbor node it
Between link be intact.If within the defined time, a certain node does not receive certain in its neighbor node again
Any information that individual node is sent, then, just it is set as that the route between the node and the neighbor node is damaged, will carries out
Localroute-repair.
The network restoration process of the dynamic routing networking technology based on flooding network, comprises the following steps：
Step 1, a certain out of touch from node, next stage node on the route is by broadcast route request message, examination
Figure finds new path and leads to host node, if success will receive the routing reply message of host node, completes route repair；
Step 2, if it fails, all nodes downstream are sent message by the node, the reason for informing routing failure,
Downstream node will re-broadcast networking request message, and application networks.
However, at least there is following three shortcomings in the existing dynamic routing networking technology based on flooding network：
1st, each sends networking request message in the form of broadcast after power-up from node, and the networking is asked
Message have passed through multiple forwarding, and this mode causes the busy of whole network channel；And host node will receive it is same from
The a plurality of networking solicited message of node, host node need to select an optimal path from numerous paths, add main section
The computational burden of point.
2nd, in the process of networking, each is required to overseas broadcast and forwarding message, multiple busy channel from node；For
Avoid conflicting, need to be monitored channel from node, and the busy channel by the way of competition.Each needed from node multiple
Busy channel adds the work load from node, it is necessary to be repeatedly at war with.
3rd, network active maintenance mechanism is lacked.The characteristic of channel of power line communication changes with the change of power load, together
Shi Yitian is to have periodic feature in the cycle, therefore the optimal path in network is also changing, and above-mentioned scheme loses in node
The reparation that can be route after contact, but lack the route assessment to whole network, Optimization route is selected again.
The shortcomings that above-mentioned 1 and shortcoming 2 cause network organizing overlong time, it is generally the case that a host node management
100 from node, it is necessary to which the networking time of about 24 hours, has had a strong impact on engineering efficiency；And shortcoming 3 does not then utilize power line
Periodic feature path is reappraised, communication is not made full use of Optimization route, had a strong impact on power information
The speed of collection.
